Actions and BMP Status Report
EXECUTIVE SUMMARY
The purpose of this report is to document the stormwater and erosion control actions that have been completed to comply with the requirements of the Conditions of Approval (COAs) for the Permanente Quarry Reclamation Plan Amendment (RPA) during the period of July 1, 2018 to June 30, 2019.
Between July 1, 2018 and June 30, 2019, Lehigh Hanson completed several actions that
ensured compliance with various COAs at the Quarry. This report lists those actions
completed and previously reported to Santa Clara County (County) and describes those
actions that have been initiated, and/or completed since the last submittal (October 1, 2018).
Actions include installation of erosion control Best Management Practices (BMPs) in order to
prevent soil erosion in areas of topsoil stockpiling; maintenance and repair of previously
installed BMPs; and the diversion of stormwater runoff to containment basins. Figures
depicting erosion control BMP installations and compliance activities from the 2018-2019
reporting year are provided in Appendix A. Further actions are ongoing as required by the RPA and COAs.

1.0 INTRODUCTION
The RPA for Lehigh Permanente Quarry (Quarry) located at 24001 Stevens Creek Boulevard, in
unincorporated Santa Clara County, amends and supersedes the previously approved 1985
Permanente Quarry Reclamation Plan for a 20-year period to satisfy the reclamation
requirements of the Surface Mining and Reclamation Act (SMARA) of 1975. The
RPA encompasses 1,238.7 acres within the Mine Operator’s 3,510-acre ownership.
Reclamation activities are being implemented in three phases over an estimated 20-year
period. The Quarry is currently in Phase I, which involves reclamation activities in the East
Material Storage Area (EMSA) and the Permanente Creek Restoration Area (PCRA) and
continuation of existing mining activities in the Western Material Storage Area (WMSA) and
Quarry Pit.
2.0 PURPOSE
The purpose of this compliance actions report is to document the stormwater and erosion
control actions that have been completed to comply with the requirements of the Santa Clara
County Conditions of Approval (COAs), approved by the Planning Commission, June 7, 2012
and modified by the Board of Supervisors on June 26, 2012. This compliance actions report
includes those actions that have been ongoing or completed since the last submittal and refer to
past actions submitted in previous reports.
3.0 REPORTING REQUIREMENTS
Generally, the COAs call for an annual report to be completed by the County by December 1 of
the year and for the mine operator, Lehigh Hanson (Lehigh), to present all data and compliance
actions to the County by October 1. To inform the annual report, Lehigh wishes to present a
report of the stormwater and erosion control actions carried out to date in order to comply with
the COAs. This report will serve to provide a record to the County and track the reclamation
actions that have been completed to date.
4.0 COMPLIANCE ACTIONS
4.1 Compliance Actions Reported in Previous Submittals
Stormwater and erosion control actions taken to address COA compliance began immediately
after RPA finalization in June 2012 and continue to present. Actions taken to address COA
compliance are required to be reported annually as per COA #8. Lehigh has submitted annual
reports of COA compliance actions as required per COA #8.
4.2 Compliance Actions Completed Since 2017-2018 Annual Report Submittal
All erosion control BMPs previously reported from previous annual reports have been
maintained and repaired as needed. Lehigh has worked with WRA, GEI, ECI (Ecological
Concerns Inc.) and Liberty Industrial to maintain effective and timely BMP management. To date,
only BMPs that have been deemed entirely non-essential have been removed or left in place.
As per COA #33, sedimentation basins are routinely inspected and cleaned of vegetation and
sediment, when necessary, to maintain good condition and proper function.Hydroseeding was
applied to areas in the Rock plant, EMSA and the Yeager Yard (see attached memo). From July
2018 – June 2019, approximately 75 cubic yards of silt was cleaned out from the silting basin in
WMSA & Rock plant areas. The silt was deposited in WMSA.
4
4.3 Planned Future Compliance Actions
Beyond the routine inspection and maintenance of existing BMPs, actions are already planned
to take place during the 2019-2020 reporting year for COA compliance. This is not meant to be a
complete list of next year’s actions and actions taken during the upcoming year will follow the
adaptive management process. Actions to complete or advance the fulfillments of the COAs
that are planned to take place during the 2019-2020 reporting year are described below.
4.3.1 Planned Hydroseeding
In order to comply with COAs #27 and #78b, Lehigh plans to hydroseed all new cleanfill
stockpiles to be used for reclamation and interim reclaimed areas that directly or indirectly drain
to Permanente Creek. Planned hydroseeding areas will receive either the “erosion control seed
mix”.
4.3.2 Potential BMP Removal
Select BMP’s, such as silt fences and straw wattles, are expected to be removed or left in
place, rather than replaced after the 2019-2020 rainy season. BMP inspections will be
performed by Lehigh’s Contractor to determine the effectiveness of BMP’s and recommend removal or leave in place.
5.0 SUMMARY
During the 2018-2019 reporting year, Lehigh provided dedicated in-house staff to regularly
oversee the erosion control BMPs and their efficacy. Lehigh preemptively addressed any
maintenance or additions needed ahead of storm events, enhancing the ability to comply with
the requirements of the COAs and the RPA in a timely manner. All BMPs and stormwater
controls were fully functional throughout the 2018-2019 rainy season. Monitoring will
continue to take place, and actions will continue to be implemented in all areas to keep within
compliance.

Subject: Permanente Quarry – September 2018 Erosion Control Inspection
Per COA 78 of the Final Conditions of Approval (COA), the Mine Operator shall:
“…regularly inspect all stormwater and erosion controls, especially before and
following qualifying rain events. Inspections shall be documented and periodically
reported. Any violations shall be corrected immediately.” And
“Ensure that all stormwater, erosion, and sediment control BMPs are installed,
inspected, maintained, and repaired under the direction of either a California
certified engineer, geologist, or landscape architect, a registered professional
hydrologist, or a certified erosion control specialist.”
WRA has been actively inspecting stormwater, erosion, and sediment control BMPs in the RPA.
WRA reports monthly on the inspections of the various BMP’s which include:
During the month of September 2018, David Zwick, WRA’s QSD conducted one monthly COA
site inspection at Permanente Quarry. The monthly COA inspection occurred on September 29,
2018 near the end of the month to assure that no unforeseen rain events may occur and affect
results of the inspection. Areas within the Lehigh Permanente Quarry inspected during WRA’s
site visit included:
The inspection noted that previous deficiencies around Pond 30, had been remedied and were
adequately addressed. The silt fence installed along the road adjacent Pond 30 was repaired. In
addition, the oil and fuel spills within this area were properly cleaned. Within the quarry, where
several slides were observed during the previous inspection, wire backed silt fence was installed
on the downhill slope of Rock Crusher Road to address the deficiencies.
BMP’s around the topsoil pile in the EMSA are inadequate. The erosion control contractor
attempted to repair previously noted deficiencies around the topsoil pile. However, repairs to the
noted deficiencies were not made to the California Stormwater Quality Association (CASQA) BMP
standard; and thus, inadequate. Specifically, the silt fence around the topsoil pile is only partially
keyed in. Erosional gullying was observed in the Yaeger Yard. The County’s suggested remedy
to minimize additional gullying was to hydroseed the area but because the rainy season has not
yet occurred, hydroseeding is still on hold.
New observed deficiencies included silt fences within the EMSA around topsoil piles, within or
beyond capacity. Material within silt fences should not accumulate to beyond 50% of the height
of the silt fence. During the time of the inspection, silt fences were observed at 60% to 85% of
the height of the silt fence. Accumulated material should be removed, or new fencing installed.
The September inspection occurred during the dry season. No qualifying rain events (>0.25
inches of rain in 24 hours) and no rainfall of any amount was recorded.
WRA will continue to perform monthly site inspections to ensure that any deficiencies that develop
in existing erosion control materials are addressed and fixed in a timely manner.

Subject: Permanente Quarry – October 2018 Erosion Control Inspection
Per COA 78 of the Final Conditions of Approval (COA), the Mine Operator shall:
“…regularly inspect all stormwater and erosion controls, especially before and
following qualifying rain events. Inspections shall be documented and periodically
reported. Any violations shall be corrected immediately.” And
“Ensure that all stormwater, erosion, and sediment control BMPs are installed,

WRA has been actively inspecting stormwater, erosion, and sediment control BMPs in the RPA.
WRA reports monthly on the inspections of the various BMP’s which include:
During the month of October 2018, David Zwick, WRA’s QSD conducted one monthly COA site
inspection at Permanente Quarry. The monthly COA inspection occurred on October 29, 2018
near the end of the month to assure that no unforeseen rain events occurred that may affect
results of the inspection. Areas within the Lehigh Permanente Quarry inspected during WRA’s
site visit included:
Hydroseeding and new BMP’s had been installed in two areas since the previous months
inspection. Hydroseeding and new BMPs were installed around top soil stockpiles and
unvegetated slopes located within the EMSA and WMSA. All new BMPs were properly applied
or installed prior to any rain events.
Previously noted deficiencies are still in need of repair including re-keying in of silt fence, or
replacement of filled silt fence around the topsoil pile in the EMSA required to meet the California
Stormwater Quality Association (CASQA) BMP standards. The QSD recommends re-keying the
silt fence, or replacing filled silt fences before the onset of the seasonal rains.
No qualifying rain events (>0.25 inches of rain in 24 hours) and no rainfall of any amount was
recorded in the month of October 2018, therefore no additional pre or post event inspections were
required.
As of October 31, 2018, WRA will no longer be performing monthly site inspections for compliance
with COA 78 at Permanente Quarry.

Dear Mr. Shivalingappa:
Re: Sediment Control and Best Management Practices (BMPs) Inspections
Lehigh Southwest Cement Company
Cupertino, California
GEI Consultants, Inc. is pleased to submit the November 2018 Sediment Control and BMPs
Inspections Report regarding the erosion controls and Best Management Practices (BMPs) at the
Lehigh Southwest Cement Company plant in support of condition No. 78 items j and l under the
“Hydrology and Water Quality” section of the Final Conditions of Approval from June 7, 2012,
which state that the Mine Operator shall:
“…regularly inspect all storm water and erosion controls, especially before and following
qualifying rain events. Inspections shall be documented and periodically reported. Any
violations shall be corrected immediately.” And,
“Ensure that all storm water, erosion, and sediment control BMPs are installed, inspected,
maintained, and repaired under the direction of either a California certified engineer,
geologist, or landscape architect, a registered professional hydrologist, or a certified
erosion control specialist.”
GEI Consultants, Inc. inspected the existing erosion control and BMPs at the Lehigh Southwest
Cement Company plant before and after the qualifying rain event in November. A qualifying rain
event is defined as “any event that produces 0.5 inches of precipitation or more with a 48-hour or
greater period between rain events.” (Construction General Permit, 2009-0009-DWQ).
The Lehigh Cement Quarry weather station gauge logged a cumulative measurement of 1.9
inches of rain between November 21 and November 24, 2018 resulting in a qualifying event.
During the month of November, approximately 4 inches of rain were measured at the quarry’s
gauge. GEI Consultants performed two field inspections at Lehigh Cement Quarry in November:
November 16, 2018: Monthly Inspection Report
• November Monthly Inspection and Pre-Rain Event Inspection
November 27, 2018: Post-rain Event Inspection Report
• Post-Rain Event Inspection for the November 21 through November 24 rain event.
January 4, 2019

During these inspections, the BMPs onsite were observed and evaluated for performance. A
summary of the inspection observations and deficiencies observed during the inspections can be
found in the attached Daily Field Reports (DFRs). The attached Site Map depicts the location
where deficiencies were observed.
BMP Deficiencies and Recommendations
The BMP deficiencies observed during the November 2018 inspections are listed on Table 1
below and were assigned a “WORK NEEDED” status in the DFRs.
Table 1. BMP Inspection Overview of Deficient Areas
Review attached DFRs and Site Maps for photos and specific locations
During the November 27 post-rain-event inspection, the BMPs throughout the site remained in
place with no immediate need for repairs. The location of BMPs’ deficiencies identified on
November 16 with a status of “WORK NEEDED” were given a status of “MONITOR FOR
CHANGES” in the November 27 DFR since the repairs were scheduled to take place in
December.
Deterioration of silt fences, especially following rain events, can lead to gaps in the fence
alignment and coverage. We recommend that Lehigh Southwest Cement Company staff regularly
monitor the silt fences and other BMPs identified in the DFRs with a status of “MONITOR FOR
CHANGES” since these BMPs are vulnerable to sedimentation and storm water flows during rain
events and their performance may become compromised.
Table 1 and the recommendations hereby included are intended to be used by Lehigh staff to
monitor the performance of and address the recommended corrective actions to the BMPs.
If you have any questions, please feel free to contact Hugo Velasquez at 510-350-2905 or Faith
Moore at 510-350-2921.

Dear Mr. Shivalingappa:
Re: Erosion and Sediment Control Best Management Practices (BMPs) Inspections
December 2018 Monthly Report
Lehigh Southwest Cement Company–Permanente Plant
Cupertino, California
GEI Consultants, Inc. is pleased to submit the December 2018 Erosion and Sediment Control
Best Management Practices (BMPs) Inspections Report regarding the implementation of BMPs at
the Lehigh Southwest Cement Company plant in support of condition No. 78 items j and l under
the “Hydrology and Water Quality” section of the Final Conditions of Approval from June 7,
2012, which state that the Mine Operator shall:
“…regularly inspect all storm water and erosion controls, especially before and following
qualifying rain events. Inspections shall be documented and periodically reported. Any
violations shall be corrected immediately.” And,
“Ensure that all storm water, erosion, and sediment control BMPs are installed, inspected,
maintained, and repaired under the direction of either a California certified engineer,
geologist, or landscape architect, a registered professional hydrologist, or a certified
erosion control specialist.”
GEI Consultants, Inc. inspected the existing erosion and sediment control BMPs at the Lehigh
Southwest Cement Company plant before and after the qualifying rain events in December. A
qualifying rain event is defined as “any event that produces 0.5 inches of precipitation or more
with a 48-hour or greater period between rain events.” (Construction General Permit, 2009-0009-
DWQ).
The Lehigh Cement Quarry weather station gauge logged a cumulative measurement of
2.14 inches of rain between December 1 and December 25, 2018 that constituted a total of three
(3) qualifying events. GEI Consultants performed two field inspections at Lehigh Cement Quarry
in December:
December 6, 2018: Post-rain Event Inspection Report
• Qualifying Rain Event from December 4 to December 6, 2018: 0.55 inches
• Month-to-date Cumulative Rain as of December 6, 2018: 0.79 inches
January 29, 2019
-2-
December 28, 2018: Post-rain Event Inspection Report
• Qualifying Rain Event from December 16 to December 17, 2018: 0.80 inches
• Qualifying Rain Event from December 24 to December 25, 2018: 0.53 inches
• Month-to-date Cumulative Rain as of December 28, 2018: 2.14 inches
As part of these inspections, the BMPs onsite were observed and evaluated for performance. A
summary of the inspection findings, BMPs’ deficiencies, and recommendations based on the
observations from the inspections can be found in the attached Daily Field Reports (DFRs). A
Site Map detailing the locations where deficiencies were observed is appended to this report.
BMPs Deficiencies and Recommendations
Based on the observations from the December 2018 inspections, BMPs at the Lehigh SW Co.
Permanente Plant are generally in good condition. BMPs identified as deficient in certain
locations were assigned a status of “Work Needed” in the respective Daily Field Report (DFR).
All recommended repairs to address the BMPs’ deficiencies identified during the December 2018
inspections have been addressed and repairs completed.
Deficiencies in BMPs that were assigned a status of “Work Needed” within either of the two
December 2018 Daily Field Reports (DFR) are tracked in Table 1 below. One BMPs deficiency
identified during the November 2018 inspections is also included in Table 1 as repairs were
completed in December 2018. Table 1 presents a brief summary of the locations, status, and
recommendations for areas where deficiencies in the implementation of erosion and sediment
control measures and implementation of BMPs were identified.
Table 1. BMPs Inspection Overview of Deficient Areas1
1 Review attached DFRs and Site Maps for photos and specific locations
2 BMPs deficiency has been addressed and repairs completed. Deficiency will be removed from Table 1 on the January 2019 report.
3 GEI to corroborate repairs during January 2019 inspection.
The status column in Table 1 reflects the most recent status identified during the December 2018
inspections by GEI; that is, if repairs were completed during December, the “Work Needed”
status has been superseded by a “Monitor for Changes” or “Good” status. Once repairs are
completed and reported by GEI regarding a particular BMPs deficiency, the deficiency is
removed from the subsequent reports—in this case, no deficiencies from December 2018 will be
included in the January 2019 report as all deficiencies were addressed and repairs completed.
No deficiencies with a status of “Work Needed” remained at the end of December; although, GEI
is to corroborate the completion of repairs during the next inspection in January since the repairs
were documented via e-mail by Lehigh staff.
We recommend that Lehigh Southwest Cement Company staff monitor the silt fences and other
BMPs assigned a status of “MONITOR FOR CHANGES” regularly since these BMPs are
vulnerable to sedimentation and storm water flows during rain events and their performance may
become compromised.
Table 1 and the recommendations hereby included are intended to be used by Lehigh staff to
monitor the condition and performance of erosion and sediment control BMPs, and to address the
recommended corrective actions to the BMPs deficiencies.

Dear Mr. Shivalingappa:
Re: Erosion and Sediment Control Best Management Practices (BMPs) Inspections
January 2019 Monthly Report
Lehigh Southwest Cement Company–Permanente Plant
Cupertino, California
GEI Consultants is pleased to submit the January 2019 Erosion and Sediment Control Best
Management Practices (BMPs) Inspection Report regarding the implementation of BMPs at the
Lehigh Southwest Cement Company plant in support of condition No. 78 items j and l under the
“Hydrology and Water Quality” section of the Final Conditions of Approval from June 7, 2012,
which state that the Mine Operator shall:
“…regularly inspect all storm water and erosion controls, especially before and following
qualifying rain events. Inspections shall be documented and periodically reported. Any
violations shall be corrected immediately.” And,
“Ensure that all storm water, erosion, and sediment control BMPs are installed, inspected,
maintained, and repaired under the direction of either a California certified engineer,
geologist, or landscape architect, a registered professional hydrologist, or a certified
erosion control specialist.”
GEI Consultants inspected the existing erosion and sediment control BMPs at the Lehigh
Southwest Cement Company plant before and after the qualifying rain events in January. A
qualifying rain event is defined as “any event that produces 0.5 inches of precipitation or more
with a 48-hour or greater period between rain events” (Construction General Permit, 2009-0009-
DWQ).
The Lehigh Cement Quarry weather station logged a cumulative measurement of 7.87 inches of
rain between January 1 and January 22 accounting for three qualifying rain events. The total
cumulative rainfall logged at the Lehigh Quarry weather station in January is 8.49 inches. GEI
Consultants performed one field inspection at the Lehigh Cement Quarry in January:
January 22, 2019: Monthly Inspection and Post-rain Event Inspection Report
• Qualifying Rain Event from January 5 to January 11, 2019: 3.41 inches
• Qualifying Rain Event from January 14 to January 17, 2019: 3.96 inches
• Qualifying Rain Event from January 20 to January 21, 2019: 0.5 inches

As part of this inspection, the BMPs onsite were observed and evaluated for performance. A
summary of the inspection findings, BMPs’ deficiencies, and recommendations based on the
observations from the inspection can be found in the attached Daily Field Report (DFR). A Site
Map detailing the location of the BMPs’ deficiencies observed is included with this report.
BMPs Deficiencies and Recommendations
Based on the observations from the January 2019 inspection, BMPs at the Lehigh SW Co.
Permanente Plant are generally in good condition. BMPs identified as deficient were assigned a
status of “Work Needed” in the DFR. All repairs associated with deficiencies from December
2018 had been completed. Recommendations of repairs to address the BMPs’ deficiencies and
other vulnerabilities identified during the January 2019 inspection are included in the DFR.
Deficiencies in BMPs that were assigned a status of “Work Needed” in the January 2019 monthly
inspection DFR are tracked in Table 1 below. Two BMPs’ deficiencies were identified during the
inspection on January 22. Table 1 presents a brief summary of the location, status, and
recommendations for the areas where the deficiencies in the implementation of erosion and
sediment control BMPs were identified.
Table 1. BMPs Inspection Overview of Deficient Areas1
1 Review attached DFR and Site Map for photos and specific locations
We recommend that Lehigh Southwest Cement Company staff monitor the silt fences and other
BMPs assigned a status of “MONITOR FOR CHANGES” regularly since these BMPs are
vulnerable to sedimentation and storm water flows during rain events and their performance may
become compromised.
Table 1 and the recommendations hereby included are intended to be used by Lehigh staff to
monitor the condition and performance of erosion and sediment control BMPs, and to address the
recommended corrective actions to the BMPs’ deficiencies.

• Qualifying Rain Event from February 12 to February 17, 2019: 5.5 inches
• Qualifying Rain Event from February 26 to February 27, 2019: 1.25 inches
As part of these inspections, the BMPs onsite were observed and evaluated for performance. A
summary of the inspection findings, BMPs’ deficiencies, and recommendations based on the
observations from the inspections can be found in the attached Daily Field Reports (DFRs). A
Site Map detailing the location of the BMPs’ deficiencies observed is included with this report.
BMPs Deficiencies and Recommendations
Based on the observations from the February 2019 inspections, BMPs at the Lehigh SW Co.
Permanente Plant are generally functional. BMPs identified as deficient were assigned a status of
“Work Needed” in the DFRs. Some repairs associated with deficiencies identified in January
2019 had not been completed due to the continuing rainfall and the potential impact of earthwork
in these conditions. Recommendations of repairs to address the BMPs’ deficiencies and other
vulnerabilities identified during the February 2019 inspections are included in the DFRs.
Deficiencies in BMPs that were assigned a status of “Work Needed” in the February 2019
inspection DFRs are tracked in Table 1 below. Two BMPs’ deficiencies were identified during
the inspections in January 2019 which we continue to track since they had not been addressed in
whole. Table 1 presents a brief summary of the location, status, and recommendations for the
areas where the deficiencies in the implementation of erosion and sediment control BMPs were
identified.

BMPs Deficiencies and Recommendations
Based on the observations from the March 2019 inspections, BMPs at the Lehigh SW Co.
Permanente Plant are generally functional and, collectively, in good condition. BMPs identified
as deficient were assigned a status of “Work Needed” in the DFRs. Some repairs associated with
deficiencies identified in February 2019 at the Rock Plant were under construction at the time of
the March inspections. These repairs resulted from sediment and debris clogging the sediment
basin discharge pipe line. Recommendations of repairs to address the BMPs’ deficiencies and
other vulnerabilities identified during the March 2019 inspections are included in the DFRs.
Deficiencies in BMPs that were assigned a status of “Work Needed” in the March 2019
inspection DFRs are tracked in Table 1 below. Two BMPs’ deficiencies were identified during
the inspections in February 2019 which we continue to track since they had not been addressed in

Re: Erosion and Sediment Control Best Management Practices (BMPs) Inspections
May 2019 Monthly Report
Lehigh Southwest Cement Company–Permanente Plant
Cupertino, California
GEI Consultants is pleased to submit the May 2019 Erosion and Sediment Control Best
Management Practices (BMPs) Inspection Report regarding the implementation of BMPs at the
Lehigh Southwest Cement Company plant in support of condition No. 78 items j and l under the
“Hydrology and Water Quality” section of the Final Conditions of Approval from June 7, 2012,
which state that the Mine Operator shall:
“…regularly inspect all storm water and erosion controls, especially before and following
qualifying rain events. Inspections shall be documented and periodically reported. Any
violations shall be corrected immediately.” And,
“Ensure that all storm water, erosion, and sediment control BMPs are installed, inspected,
maintained, and repaired under the direction of either a California certified engineer,
geologist, or landscape architect, a registered professional hydrologist, or a certified
erosion control specialist.”
GEI Consultants inspected the existing erosion and sediment control BMPs at the Lehigh
Southwest Cement Company plant once since there were no qualifying rain events during the
month of May 2019. A qualifying rain event is defined as “any event that produces 0.5 inches of
precipitation or more with a 48-hour or greater period between rain events” (Construction
General Permit, 2009-0009-DWQ).
Without any qualifying rain events during May 2019, GEI Consultants performed a single
inspection May 30, 2019 as the monthly inspection.
As part of the inspection, the BMPs onsite were observed and evaluated for performance. A
summary of the inspection findings, BMPs’ deficiencies, and recommendations based on the
observations from the inspection can be found in the attached Daily Field Report (DFR). A Site
Map detailing the location of the BMPs’ deficiencies previously observed and resolved during
May 2019 is included with this report.

BMPs Deficiencies and Recommendations
Based on the observations from the May 2019 inspection, BMPs at the Lehigh SW Co.
Permanente Plant are generally functional and, collectively, in good condition. No deficiencies
were encountered during the May 2019 inspection.
Repairs associated with deficiencies identified in early 2019 at the Rock Plant were completed
following the April 2019 inspection. One deficiency in BMPs was assigned a status of “Work
Needed” in the April 2019 inspection report and remained tracked in Table 1 below to note that
the repairs were completed. These repairs included the removal of sediment and debris clogging
the sediment basin discharge pipe line and the replacement of a pipe segment with a riprap apron
and swale at the point of discharge.
Table 1 presents a brief summary of the location, status, and recommendations for the Rock Plant
area, where the implementation of erosion and sediment control BMPs was identified as deficient.

Re: Erosion and Sediment Control Best Management Practices (BMPs) Inspections
June 2019 Monthly Report
Lehigh Southwest Cement Company–Permanente Plant
Cupertino, California
GEI Consultants is pleased to submit the June 2019 Erosion and Sediment Control Best
Management Practices (BMPs) Inspection Report regarding the implementation of BMPs at the
Lehigh Southwest Cement Company plant in support of condition No. 78 items j and l under the
“Hydrology and Water Quality” section of the Final Conditions of Approval from June 7, 2012,
which state that the Mine Operator shall:
“…regularly inspect all storm water and erosion controls, especially before and following
qualifying rain events. Inspections shall be documented and periodically reported. Any
violations shall be corrected immediately.” And,
“Ensure that all storm water, erosion, and sediment control BMPs are installed, inspected,
maintained, and repaired under the direction of either a California certified engineer,
geologist, or landscape architect, a registered professional hydrologist, or a certified
erosion control specialist.”
GEI Consultants inspected the erosion and sediment control BMPs at the Lehigh Southwest
Cement Company plant once since there were no qualifying rain events during June 2019. A
qualifying rain event is defined as “any event that produces 0.5 inches of precipitation or more
with a 48-hour or greater period between rain events” (Construction General Permit, 2009-0009-
DWQ). Without any qualifying rain events during June 2019, GEI Consultants performed a single
inspection June 25, 2019 as the monthly inspection of BMPs.
As part of the inspection, the BMPs onsite were observed and evaluated for performance. A
summary of the inspection findings, BMPs’ deficiencies, and recommendations based on the
observations from the inspection can be found in the attached Daily Field Report (DFR). A Site
Map identifying the various locations of the BMPs inspected on June 25th is included with this

RECLAMATION PLAN AMMENDMENT AND FINAL CONDITIONS OF APPROVAL ANNUAL
WORKER TRAINING
Lehigh Southwest Cement Company
24001 Stevens Creek Boulevard
Cupertino, California 95014

Memo
To: Ms. Tressa Jackson From: Manjunath Shivalingappa
Copy: NA Date: 09-23-2019
Subject: RPA Training Topics
RECLAMATION PLAN AMENDMENT AND FINAL CONDITIONS OF APPROVAL
TRAINING TOPICS
Per the Final Conditions of Approval number 11 (COA 11), Lehigh shall annually train all mining
staff, including outside vendors, contractors, or consultants who are responsible for
implementation of any part of the mine operations or reclamation at Permanente Quarry, on the
requirements and provisions of the RPA, the conditions of approval, and the MMRP.
Reclamation Plan Amendment (RPA) and Provisions
Approval of the project would amend the existing reclamation plan for the Quarry and would
result in the reclamation of an approximately 1,238-acre project area within the Applicant’s
overall 3,510-acre ownership. The Project is designed to make the reclaimed lands suitable for
future open space uses. It includes site-specific activities to satisfy the reclamation requirements
of the Surface Mining and Reclamation Act of 1975 and the County’s surface mining ordinance
and surface mining and land reclamation standards. The Project would be implemented in three
phases over an approximately 20-year period, expected to begin in 2012 and conclude with final
reclamation by approximately 2030.
As part of the RPA approval process, mitigation measures and provisions were agreed upon for
the project. The Project Draft Environmental Impact Report (EIR) and Final EIR describe the
various conditions and activities that the quarry must adhere to through the project. Quarry staff
shall be aware of the conditions of approval that correspond to their job descriptions and
responsibilities. These are listed and described throughout the Reclamation Plan Amendment,
which is available for all quarry staff to view as needed.
Final Conditions of Approval
The County issued a Final Conditions of Approval which contains 89 different Conditions of
Approval which shall be met by the Quarry. Quarry staff shall be aware of the COA’s and be
knowledgeable in those COA’s which correspond to their job descriptions and responsibilities. A
copy of the Final COAs is available for all quarry staff to view as needed.

PREVENTION OF TRIGGERING DEBRIS SLIDES
As a condition of approval for the Reclamation Plan Amendment, the County has mandated that
mine operators shall be trained in the prevention of triggering debris slides. This is targeted at
keeping sediment, especially limestone-based materials, from entering Permanente Creek and
PCRA areas.
Please discuss the following topics with all employees:
1. General awareness of the causes and impacts of debris slides.
Debris slides can occur on steep hillsides where consolidation of the substrate
cannot support the loads above. Slides usually happen where fill slopes are steep and
composed of loose materials. Any loosening or disturbance of supporting materials can
cause a debris slide.
2. Maintaining thorough and adequate erosion control measures.
Controls to prevent materials from sloughing off include debris/silt fencing placed on
outer edge of grading and excavation operations, back-sloping excavations to prevent
grade slope towards the creek, operations buffer areas, and berms along the outer
extent of operations closest to the creek.
At the Permanente Quarry, the main control is the haul road berms to prevent
materials from entering the PCRA. Secondary controls are installed on the slopes below the
haul road berm in various subareas on the creek slopes including erosion control matting,
straw wattles, and wire-backed silt fencing.
3. Prevention of actions that may cause or exacerbate debris slide conditions
Avoid unnecessarily removing vegetation, boulders and other substrates. Restrict
vehicle operations to maintained roads. Stockpile fill and other debris in appropriate
areas as designated with the haul road berms.
4. Regularly inspect areas with a high potential for slides and report any suspected
conditions that might cause a debris slide into Permanente Creek and PCRA areas.
Memo to: Ms. Tressa Jackson

EROSION CONTROL TRAINING TOPICS
Erosion control is the practice of preventing or controlling wind or water erosion in agriculture,
land development and construction. Effective erosion controls are important techniques in
preventing water pollution and soil loss. Erosion controls are used in natural areas, agricultural
settings or urban environments. Erosion controls often involve the creation of a physical barrier,
such as vegetation or rock, to absorb some of the energy of the wind or water that is causing
the erosion. On construction sites they are often implemented in conjunction with sediment
controls such as sediment basins and silt fences.
On the Permanente Quarry Site, the main erosion controls include:
• Haul road berms to keep water out of the creek and directed toward siltation basins or
ponds
• Siltation basins or ponds to settle out sediment and control waters leaving the site
• Silt fences, straw wattles, and erosion control blankets on the creek side of the haul road
berms in select locations
• Silt fences, straw wattles, and erosion control blankets on the topsoil stockpiles
6 Goals Of Erosion Control
1. No Sediment Leaves the Site
2. Lines of Defense Everywhere & Always
3. Cover Quickly
4. Protect the Swale, Ditch ,and Channel
5. Keep Clean Water Clean
6. Inspect, Clean & Fix
Inlet Barriers (i.e.: sand bags, gutter buddies, straw wattles)
• Is the structure deteriorating
• Is sediment >1/2 the height of structure?
• Evidence of water/sediment getting around or under barrier?
• Are there other structures that require inlet barriers?
Sediment Barriers (i.e.: haul road check dams, ditch checks)
• Are they trenched in or falling down?
• Evidence of sediment/water getting around or under barrier?
• Is sediment more than 1/2 height of structure?
• Are there areas where more sediment barriers are required or need extended?
Perimeter Control (i.e.: Haul road berms, silt fence, straw wattles)
• Is all the off-site water being diverted where applicable?
• Evidence of water/sediment getting around or under barrier?
• Are there areas that need extended or additions to other locations?
• Are the barriers in good condition or in need of repair?
• Straw Blankets-are they deteriorating and need replaced?
• Are the haul road berms preventing water from entering the creek?
Memo to: Ms. Tressa Jackson
09-23-2019
Page 2
Stabilized Construction Entrance
• Evidence of sediment being tracked off site onto public streets?
Soil and Fines Stockpiles
• An earth berm must be constructed upstream around the area to prevent runoff from
contacting stockpile and a downstream ditch to prevent waters from leaving the stockpile
site
Sediment Basins
• Note the basin depth. Is the basin more than half full of sediment from original design?
• Condition of basin side slopes
• Evidence of water overtopping embankments
• Condition of outfall
General Site Conditions
• Trash barrels-any evidence of trash lying around site
• Location of portable restrooms
• Leaking vehicles
• Concrete Washouts Designated

STORM WATER POLLUTION PREVENTION PLAN: BMP’S
Best Management Practices (BMPs) are practices used to reduce the amount of pollution
entering surface waters. Based on the potential pollutant areas identified at the facility, existing
and recommended BMPs for the facility are discussed below.
Please discuss the following areas with all employees:
1) Truck Loading Areas
a. Continue to immediately cleanup any spilled cement or aggregate.
2) Raw Material Storage
a. Any total suspended solids (TSS) generated by stormwater contact with the
aggregate storage areas is directed to detention ponds or basins which are
designed to remove TSS prior to discharge. BMP in these areas would be to
insure that stormwater runoff from aggregate storage or cement loading areas
does not leave the property, but indeed goes to ponds or basins.
b. Maintain bag houses to prevent dust from cement. Immediately cleanup any spill
material to limit exposure to stormwater.
3) Secondary Containment Storage
a. Secondary containment walls should be maintained, inspected and repaired
when necessary to prevent leaks. Secondary containment is defined as spill
containment for the contents of the single largest tank plus sufficient freeboard
to allow for a 25 year, 24 hour storm event.
b. Maintain the equipment and hoses within the containment area used to transfer
the materials. Clean inside walls when necessary.
4) Diesel Tanks
a. Fuel overflows during storage tank filling can be a major source of spills.
Watch the transfer constantly to prevent overfilling and spilling.
b. Clean up any spills or drips immediately.
c. Verify that drain plug is installed.
d. Discourage topping off of fuel tanks.
e. Properly protect portable fuel tanks, pumps and hoses from contact with trucks
and other mobile equipment.
f. Install secondary containment around tank pump and piping if not already done,
this would prevent a leak or spill from entering ponds, basins or from leaving the
property.
5) Oil Storage Areas
a. Place all drums and lubricants on drip containment pallets.
b. Clean up any spills or drips with sorbent materials immediately.
c. Maintain valves to prevent leaks.
d. Clean out within containment when necessary. Inspect for residue prior to
rainwater release. Remove old & unused barrels
Memo to: Ms. Tressa Jackson
09-23-2019
Page 2
6) Ponds and Basins
a. Inspect basins regularly for damage, erosion, waste, and sediment buildup.
b. Clean out basins when necessary to prevent a stormwater overflow.
c. Reduce amount of sediment and processed water to keep basins level low.
d. Inspect outfall regularly for dry weather discharge.
7) Sediment Drying Areas
a. Inspect area regularly for damage, erosion, waste, and sediment buildup.
b. Clean out area when necessary to prevent a stormwater overflow.
c. Reduce amount of sediment to keep sediment levels low.
8) Equipment Wash Areas
a. Continue to wash mobile equipment to the basins and direct all wash water to
prevent it from leaving the containment area
b. Keep area swept and free of aggregates, fines and trash that could enter the
ponds, basins or leave property.
c. Inspect area regularly for damage and erosion.
REMEMBER:
Keep tanks inside secondary containment.
• Prevent a leak or spill from entering the ponds, basins or leaving the property.

CULTURAL RESOURCES IDENTIFICATION AND PRESERVATION
Because cultural artifacts have been encountered on the Quarry site, mine operators shall be
trained in the identification of archaeological artifacts and preservation of those resources.
Please discuss the following topics with all employees:
1. General awareness of COA 65.
If cultural resources are encountered the Mine Operator shall notify the Planning
Manager and all activity within 100 feet of the find shall stop until the cultural resource is
evaluated by a qualified archaeologist and a Native American representative. Ground
disturbance shall not resume within 100 feet of the find until an agreement has been
reached as to the appropriate treatment of the find
2. Identification of Cultural Resources:
a. Prehistoric Archaeological Materials might include:
i. Obsidian and chert flaked-stone tools (e.g., projectile points, knives,
scrapers) or toolmaking debris;
ii. Culturally darkened soil (“midden”) containing heat-affected Rocks,
artifacts, or shellfish remains;
iii. Stone milling equipment (e.g., mortars, pestles, handstones, or milling
slabs); and battered stone tools, such as hammerstones and pitted
stones.
b. Historic-period materials might include:
i. stone, concrete, or adobe footings and walls;
ii. filled wells or privies;
iii. deposits of metal, glass, and/or ceramic refuse.

Golder Associates Inc. (Golder) has prepared this technical memorandum to document the activities
completed at the Lehigh Permanente Quarry from July 1, 2018 through June 30, 2019 related to the
Reclamation Plan Condition of Approval (COA) 76. COA 76 pertains to water quality monitoring and states the
following:
Within ninety (90) days of RPA approval, the Mine Operator shall begin and continue throughout the
backfilling and reclamation phases and for 5 years following completion of reclamation and for 5 years
following the start of groundwater discharge from the Quarry Pit into Permanente Creek as described on
page 4.10-39 of the Final Environmental Impact Report, a Verification and Water Quality Monitoring
Program. The Mine Operator shall implement the following:
a. Collect quarterly Quarry pit water samples and analyze for general water chemistry and dissolved and
total metals, including selenium.
b. Perform quarterly electrical conductivity and pH measurements of the Quarry water.
c. Measure and record daily volume of any water that is pumped from the pit area.
d. Conduct annual seep surveys in March or April of each year within the Quarry pit. Any seeps shall be
sampled for general water chemistry and minerals and dissolved metals, and the seep flow rate shall
be estimated.
e. Perform routine testing of each of the various rock types that comprise the overburden to further
characterize bulk and leachable concentrations of key metal constituents (selenium in particular).
Such testing shall be performed until the average concentrations and the variability within a rock type
is no longer changing significantly as new data are gathered.
f. Sample and test runoff from the EMSA and WMSA throughout and following reclamation to confirm
the concepts and closure plans (i.e., that cover with non-limestone material and re-vegetation results
in runoff water quality that meets Basin Plan Benchmarks and all other applicable water quality
standards, including, but not limited to, a site specific NPDES permit for the Quarry and a TMDL for
selenium in Permanente Creek). Stormwater runoff monitoring and sampling shall be conducted
following the placement and final grading of the 1 foot run-of-mine non-limestone cover material to
ensure that surface water discharging from this cover does not contain selenium at concentrations
exceeding Basin Plan Benchmark values. Three rounds of representative surface water samples shall
be collected and analyzed to verify rock cover performance prior to the placement of the vegetative
growth layer.

g. Sample and test groundwater discharge from the Quarry Pit into Permanente Creek following
reclamation as described on page 4.10-39 of the Final Environmental Impact Report to confirm that
water quality in discharge meets Basin Plan Benchmarks and all other applicable water quality
standards.
h. The data obtained through this mitigation measure shall be used to reevaluate the water balance
components such as runoff and groundwater inflow and the water quality associated with these within
the last five years of active mining. Based on the results of any refined water balance and water
quality projections, the Mine Operator shall also review and refine the water management procedures.
(Implements Mitigation Measures 4.4-5 and 4.10-1b.). All testing data shall be submitted to the
Planning Office with the Annual Report by October 1 of each year.
The following provides a summary of tasks completed:
a. Collect quarterly Quarry pit water samples and analyze for general water chemistry and dissolved
and total metals, including selenium.
From July 1, 2018 through June 30, 2019, samples were collected from the effluent of the EFF-001U and
EFF-001L discharges from the final treatment systems (Table 1). The influent includes water from the Quarry, Cement Plant Reclaim Water, and the Pond 30 drainage. The samples were analyzed for total metals and/or general water chemistry parameters.
Table 1 also includes the discharge data from Ponds 9, 13b, 17, and 30 from July 1, 2018 through June 30, 2019. Ponds 13b and Pond 30 did not discharge during this time period.
b. Perform quarterly electrical conductivity and pH measurements of the Quarry water.
Electrical conductivity (EC) measurements were not taken as samples were analyzed for TDS directly (i.e., EC is a surrogate for TDS laboratory data). Total dissolved solids (TDS) and pH measurements are included on
Table 1.
c. Measure and record daily volume of any water that is pumped from the pit area.
Daily records of volume of water, including water pumped from the pit, and treated and discharged through permitted discharge points EFF-001U (by Pond 4) and EFF-001L (by Pond 1) are included on Table 1 under EFF-001U and EFF-001L.
d. Conduct annual seep surveys in March or April of each year within the Quarry pit. Any seeps shall
be sampled for general water chemistry and minerals and dissolved metals, and the seep flow rate
shall be estimated.
On April 30, 2019, Golder performed a seep survey within the Quarry pit. Three seeps were identified during the survey similar to last year:
Manjunath Shivalingappa Project No. 1655230-03
Lehigh Southwest Cement Company 9/24/2018

Golder did not identify any additional seeps within the Quarry pit. During the seep survey, the identified seeps were sampled and analyzed for general water chemistry and dissolved metals. The results of the sampling and the estimated flow rates are shown on Table 2. Selenium results from the three samples ranged from 2.6 micrograms per Liter (μg/L) from Seep-750 to 41 μg/L from Seep-1200. Nickel results ranged from 6.1 μg/L to 61 μg/L. The estimated flow rate of the seeps ranged from 3 gallons per minute (gpm) for Seep-750 to 200 gpm for Seep-850.
e. Perform routine testing of each of the various rock types that comprise the overburden to further
characterize bulk and leachable concentrations of key metal constituents (selenium in particular).
Such testing shall be performed until the average concentrations and the variability within a rock type
is no longer changing significantly as new data are gathered.
Samples of the primary overburden materials located within the quarry were collected and analyzed in 2014.
The samples were collected of the Santa Clara Formation, greenstone, and graywacke and were submitted for laboratory analysis for total selenium and for leaching potential via the waste extraction test (WET). Total selenium was not detected above the laboratory method detection limit of 0.022 milligrams per kilogram (mg/kg). WET results ranged from non-detect to 1.5 μg/L.
Lehigh completed additional characterization work in 2018.1 Included with this characterization work were the collection and analysis of samples of the overburden material consisting of greenstone and graywacke. The work was completed in part to provide information on acid rock drainage (ARD) potential, chemical and mineralogical composition, and leaching potential via the California modified WET analysis with DI water. The rock samples were collected from drill core and surface locations and included the following:
The results were consistent with previous work and are included as Tables 3 and 4. Total selenium was not detected above the laboratory method detection limit of 0.022 milligrams per kilogram (mg/kg); WET results ranged from non-detect to 1.8 μg/L.
f. Sample and test runoff from the EMSA and WMSA throughout and following reclamation to confirm
the concepts and closure plans (i.e., that cover with non-limestone material and re-vegetation results
in runoff water quality that meets Basin Plan Benchmarks and all other applicable water quality
standards, including, but not limited to, a site specific NPDES permit for the Quarry and a TMDL for
selenium in Permanente Creek). Stormwater runoff monitoring and sampling shall be conducted
following the placement and final grading of the 1 foot run-of-mine non-limestone cover material to
ensure that surface water discharging from this cover does not contain selenium at concentrations
exceeding Basin Plan Benchmark values. Three rounds of representative surface water samples shall
be collected and analyzed to verify rock cover performance prior to the placement of the vegetative
growth layer.
During the 2018/2019 wet season, Lehigh managed stormwater runoff in the EMSA by pumping accumulated water in the collection vault to Pond 11 and the Cement Plant reclaim water system for treatment by the final treatment system prior to discharging to Permanente Creek under Lehigh’s NPDES permit.2 A total of 6,543,261 gallons, of which 3,116,100 gallons originated from the French drain, was pumped to Pond 11 from 1 Golder Associates, Preliminary Closure Plan, Lehigh Southwest Cement Company Permanente, June 2019 2 Golder Associates, Memorandum, EMSA Stormwater Management Update, Lehigh Permanente Facility, Santa Clara County, CA, February 1, 2019

the collection vault. Lehigh collected samples for selenium analysis from the vault and the French drain
throughout the wet season prior to transferring the water to Pond 11 for treatment prior to being discharged.
The results are summarized below:
Table 5: Operations Summary Table
Golder completed the wet season monitoring program, which included the collection of water samples from similar locations as previous years (Figure 1). Under the direction of a California Professional Geologist, Golder personnel collected samples from 14 locations in January and February 2019 during three rain events.
Golder attempted to collect samples during a late season rain event in April 2019; however, the sample
locations were dry. Additionally, several of the previous locations were dry during all or some of the sampling events.
Golder inspected the EMSA for runoff and/or sheet flow to target these areas for sampling. Similar to previous years, rainfall appeared to readily infiltrate the EMSA material in locations where no significant runoff or sheet flow was observed by field staff during the storm events. Most of the samples were collected of water that accumulated on the non-limestone interim cover material cover material, where water appeared to be emanating as seeps from the toe of the EMSA slopes, and from the drainage conveyance system. The type of sample and results are noted on Table 2. Selenium detected in samples of water that accumulated on the non-limestone interim cover material ranged from non-detect to 2.8 μg/L. Results from samples collected along the toe of the EMSA slopes (e.g., EC-16) ranged from 18 μg/L to 75 μg/L. These samples are considered more representative of seeps emanating from the toe of the slopes than direct runoff of the cover material. Samples were collected from the drainage swale and the upstream conveyance system, including Ponds 31A and 31B. Results ranged from 8.1 μg/L to 56 μg/L. The higher results were noted from sample locations along the drainage swale just west of Pond 30.
As part of the wet season monitoring program, sediment samples were collected from three of the locations that were sampled previously: eastern edge of Pond 30 (PD30-SD3), along the eastern portion of the drainage swale (Swale-SD1) and form the western portion of the drainage swale (Swale-SD2). Sample locations are Manjunath Shivalingappa Project No. 1655230-03

shown on Figure 1. Samples were not collected from all of the previous Pond 30 locations because of safety concerns accessing the pond. At each location, Golder collected a surficial sample and then a deeper sample from one foot below ground surface (bgs). The deeper sample was collected to evaluate potential differences with depth. The samples were collected with a hand auger or shovel and plastic scoops and placed in laboratory provided glass jars. Samples were transported to a certified analytical laboratory where the laboratory analyzed the samples for total selenium. Based on the total results, two samples were analyzed for leaching potential via the California modified WET analysis with DI water
The total selenium concentrations were non-detect for all samples except from the shallow sample collected at from Pond 30 where selenium was detected at an estimated value of 1.4 milligram per kilogram (mg/kg) (Table 5). Both samples from PD30-SD3 were selected for WET analysis. WET selenium results were 0.0074 mg/L (7.4 μg/L) from the shallow interval and non-detect from the deeper interval. The WET data along with the total results suggest that the sediment is not a primary source of selenium in water, consistent with previous years.
g. Sample and test groundwater discharge from the Quarry Pit into Permanente Creek following
reclamation as described on page 4.10-39 of the Final Environmental Impact Report to confirm that
water quality in discharge meets Basin Plan Benchmarks and all other applicable water quality
standards.
This task is to be completed after reclamation activities are complete.
h. The data obtained through this mitigation measure shall be used to reevaluate the water balance
components such as runoff and groundwater inflow and the water quality associated with these within
the last five years of active mining. Based on the results of any refined water balance and water
quality projections, the Mine Operator shall also review and refine the water management procedures.
(Implements Mitigation Measures 4.4-5 and 4.10-1b.). All testing data shall be submitted to the
Planning Office with the Annual Report by October 1 of each year.
This task is ongoing.

1.0 INTRODUCTION
Golder Associates Inc. (Golder) has prepared this Stormwater Pollution Prevention Plan (SWPPP) for the Lehigh
Southwest Cement Company’s Permanente Plant (Facility) located at 24001 Stevens Creek Blvd., Cupertino,
Santa Clara County, California. The Facility is a limestone quarry and cement production facility that also
produces construction aggregate. Lehigh Southwest Cement Company operates the Facility, which is owned and
Hanson Permanente Cement, Inc., (Lehigh) owns.
The Facility’s surface water discharges, including stormwater, are regulated by waste discharge requirements
(WDRs) in Order Number R2-2014-0010 and amended per Order No. R2-2017-0030, National Pollutant
Discharge Elimination System (NPDES) Permit Number CA0030210 (NPDES Permit).
The NPDES permit prohibits any process water-related discharges except through a single, treated, discharge
point (Discharge Point 001, Pond 4A), such that all remaining discharge points are comprised of stormwater
and/or authorized non-stormwater.,
Golder has prepared this SWPPP on behalf of Lehigh consistent with Provision C.6.a of the NPDES Permit. The
NPDES Permit requires Lehigh to prepare a SWPPP that contains information and describes measures
consistent with the requirements in Waste Discharge Requirements for Discharges of Storm Water Associated
with Industrial Activities Excluding Construction Activities, NPDES General Permit No. CAS000001 (State Water
Board Order No. 97-03-DWQ), Section A, Storm Water Pollution Prevention Plan Requirements (General Permit).
The NPDES Permit Provision VI.C.6 also provides SWPPP requirements.
The NPDES prohibitions limit discharges from Discharge Point Nos. 002 – 006 (Ponds 13B, 9, 17, 20, and 30)
except as a result of precipitation, or to discharge stored water and the effluent limitations include numerical limits
applied to total suspended solids (TSS), oil and grease (O&G), pH, settleable matter, and turbidity. The NPDES
Permit also includes stormwater action levels for certain metals, conductivity, visible oil, and visible color that will
be considered in this SWPPP.
Stormwater in several drainage areas, or catchment areas, of the Facility are comingled with process waters, and,
therefore, the NPDES Permit requires that these catchment areas be discharged through a single, treated
discharge point (Discharge Point No. 001). Discharge Point No. 001 is covered under different facility plans.
The purpose of the SWPPP is to protect surface water quality by reducing the amount of pollutants in stormwater
runoff for Discharge Point Nos. 002 through 006. The industrial activities at the Facility generally include mining,
processing of minerals, production of Portland cement, storage of construction aggregates.
The SWPPP has two major objectives:
Preparation of this SWPPP does not guarantee compliance with the NPDES Permit. It is the responsibility of Lehigh to implement the necessary BMPs and recommendations set forth in this document.
October 15, 2018 1665523002
2
This SWPPP has been prepared by Golder for the exclusive use of Lehigh. Golder prepared this SWPPP based
upon information provided by Lehigh and a site visit conducted by George Wegmann and Mark Naugle, PE of
Golder on April 21, 2014 and Mark Naugle on October 2, 2018. This SWPPP is revised as needed.
2.0 STORMWATER PLANNING AND ORGANIZATION
This section of the SWPPP identifies specific individuals that comprise the Lehigh Pollution Prevention Team
(PPT) that are responsible for developing, implementing, and revising the SWPPP. The PPT will review the
SWPPP annually and update the SWPPP as necessary. This SWPPP is a public domain document.
2.1 Position Responsibilities
The Plant Manager provides overall management of the implementation of this SWPPP. The Stormwater Team
Leader/ Environmental Manager provides coordination of the implementation of this SWPPP.
2.2 Pollution Prevention Team
The PPT will help the Plant Manager implement the SWPPP, identify necessary SWPPP revisions, and conduct
required monitoring activities. The Lehigh PPT is further described in the following sections.
Table 1: Pollution Prevention Team
2.2.1 Team Responsibilities
The PPT is comprised of several key individuals as shown in Table 1. Each member is listed in the table along
with his/her job title and responsibilities. The PPT is responsible for:
October 15, 2018 1665523002

2.2.2 Responsible Persons
Keith Krugh, plant manager, is the Responsible Person (RP) for stormwater pollution prevention at this facility,
and is responsible for oversight of:
The designated Alternate RP, environmental engineer Manju Shivalingappa, will perform these duties in the
absence of the RP.
2.3 Other Requirements and Existing Facility Plans
The Facility’s air emissions are regulated by a Title V – Major Facility Review Permit issued by the Bay Area Air Quality Management District (BAAQMD). According to BAAQMD Condition 24621, Lehigh maintains and implements a Fugitive Dust Control Plan (Lehigh 2010) consistent with the Title V permit. Control measures identified in this plan will reduce the generation of particulates that could be exposed to stormwater at the Facility.
The NPDES Permit requires that Lehigh develop a Facility Reliability Assurance Plan (FRAP) no later than May 16, 2014 that describes measures in place to ensure the reliability of the Facility’s system in preventing inadequately treated wastewater from being discharged and in preventing catastrophic failures of ponds.
Wastewater will be referred to herein as process water and includes process water from the Reclaim Water System, Quarry, and Primary Crusher and stormwater which comingles with process water.
The NPDES Permit requires that Lehigh maintain a BMP Plan in usable condition and available for reference and use by all appropriate personnel. The BMP Plan shall be developed and implemented to minimize the potential impact of periodic discharges to Permanente Creek, to prevent the accidental release of toxic or hazardous substances into the environment, and to minimize and mitigate the effects of any such releases using equipment and techniques available and practical for such use. The BMP Plan will be consistent with U.S. EPA’s Guidance Manual for Developing Best Management Practices (October 1993, EPA 833-B-93-004) and will, at minimum, include BMPs described in NPDES General Permit No. CAS000001 (State Water Board Order No. 97-03-DWQ), Section A, Storm Water Pollution Prevention Plan Requirements.
Other plans that describe the management of materials and practices at this facility, which may affect the management of stormwater include the following (these plans are NOT a part of the SWPPP).
3.0 FACILITY DESCRIPTION
The following sections describe the Facility layout, industrial activities, and significant materials. Significant
materials are those materials that should be considered when assessing potential stormwater pollutants.
October 15, 2018 1665523002
4
3.1 Facility Location and Layout
The Facility is located at 24001 Stevens Creek Road in the southern San Francisco Bay Area, in the foothills of
unincorporated western Santa Clara County, just west of the City of Cupertino, California, as shown on Figures 1
and 2. The climate of the southern San Francisco Bay Area is Mediterranean, characterized by mild, wet winters,
and warm, dry summers.
Lehigh mines and processes minerals at the Facility and produces Portland cement from limestone and stone
quarried onsite. As shown on Figure 2, the Facility consists mainly of an active mining area (quarry), primary
crusher, a cement plant, rock plant, material storage areas, roads, and a conveyor system for transporting the
processed materials.
3.2 Surrounding Activities and Structures
Land to the west of the Facility is open space. Stevens Creek Quarry is located to the south of the Facility
(Figure 2) along with rural residential areas and small agricultural operations including some vineyards. Land uses
to the east of the Facility include open space and recreational areas along with residential subdivisions. North of
the Facility is open space and recreational areas. The areas surrounding the Facility that might produce run-on
include vegetated slopes.
3.3 Site Drainage
The Facility lies within the Permanente Creek watershed. Permanente Creek discharges into southern San
Francisco Bay. Precipitation that falls within the Facility is managed within six catchment areas. These catchment
areas are shown on Figure 3. The catchment areas are identified by the retention basins or ponds where
stormwater runoff within the catchment areas is captured. The ponds discharge via standpipe and culverts to
Permanente Creek.
The stormwater discharges are identified in the NPDES permit as Discharge Point Nos. 002 through 006. The
stormwater related catchment areas and associated discharge locations are listed below:
Each of the stormwater drainage areas is described in the following sections. As noted previously, stormwater in
several catchment areas (Reclaim Water System including the Cement Plant and Truck Wash) of the Facility are
comingled with process waters and is treated and discharged under Discharge Point No. 001. Since 2014, Lehigh
has made numerous Facility improvements to divert more stormwater to the Reclaim Water System from the
stormwater discharge catchments (Discharge Point Nos. 002 through 006).
3.3.1 Pond 13B (Discharge Point No. 002)
Pond 13B is located upgradient of the north bank of Permanente Creek. Stormwater runoff runs down the slope to
Pond 13B. The location of Pond 13B and the associated catchment are provided in Figure 4.
October 15, 2018 1665523002
5
Water in Pond 13B is typically retained, evaporates, and/or infiltrates. Pond 13B also has an overflow pipe to
allow direct discharge to Permanente Creek if the water level in the pond reaches the elevation of the overflow
pipe. The inlet to the overflow pipe is at the top of the pond side slope at the downgradient end of the pond. The
overflow pipe is a 24 inch corrugated metal pipe (CMP) that conveys the overflow waters down the slope,
approximately fifty feet, in a controlled fashion, into Permanente Creek. Since at least May 2007, no direct
discharge from Pond 13B through this overflow pipe has been observed.
3.3.2 Pond 9 (Discharge Point No. 003)
Pond 9 is located adjacent to a road, near the north bank of Permanente Creek, south of the cement plant. The
location of Pond 9 is provided in Figure 5. Formerly, Pond 9 received stormwater runoff from upgradient roads
and hillsides, the Surge Pile, the cement plant stockpile storage, upper equipment storage area, and pumped
water from the Dinky Shed Catchment. Pond 9 also formerly received excess process and/or stormwater from the
Reclaim Water System that was pumped from Pond 11, (which was permitted under the CDO until October 1,
2014).
Because of the presence of the California red-legged frog (a threatened species) discovered in Pond 9, Lehigh
has worked to redirect any stormwaters flowing through process areas from reaching the pond. The pond only
receives stormwater from adjacent slopes, and upwelling ground or creek water from beneath the pond. A
groundwater seep originating near the western portion of the rock plant may reach Pond 9 via a half CMP and
drainage swale. The permit was amended to reflect this change, modify the sampling requirements, and remove
the effluent limitations and stormwater action levels for this discharge.
The Dinky Shed Catchment may receive stormwater runoff that has been diverted from Pond 9, as well as water
from a lower section of the Facility’s Rock Plant access road. (Runoff from the upper section of the road flows to
Pond 17.) Water from the Dinky Shed Catchment is pumped to Pond 1.
3.3.3 Pond 17 (Discharge Point No. 004)
Pond 17 was designed to discharge stormwater flows from the Rock Plant area into Permanente Creek. The Rock
Plant stormwater is diverted toward the Dinky Shed, through Pond 20 (Discharge Point No. 005), and/or
Discharge Point No 004 (Figure 6).
In the southern part of the Rock Plant is a haul road that heads south upslope towards Stevens Creek Quarry to
the south as shown on Figure 8. The road is graded to drain along a ditch on the west side of the road. About
halfway down the road there is a catch basin that collects water in the ditch and discharges to a drain pipe that
conveys runoff down the slope and discharges at the bottom of the slope. Runoff from the road then flows
overland to Pond 20 or could be diverted to Pond 17.
The stormwater in this area includes rain falling directly on the Rock Plant and the haul road; stormwater from
portions of the adjacent hillsides is diverted by pipeline B as to prevent run-on from entering the Rock Plant area.
3.3.4 Pond 20 (Discharge Point No. 005)
Pond 20 is located at the base of a slope south of the historical, non-operational, former Aluminum Plant and
general plant entry road. The location of Pond 20 and the associated catchment is provided in Figure 7. Pond 20
is a shallow depression that receives stormwater runoff from the slope, a small section of the road opposite to
former Aluminum Plant, and the entry road directly or from Pond 19, which drains the same catchment area. Pond
20 also receives some water from the Rock Plant road. The discharge from Pond 20 continues to flow easterly
through vegetation, including Pond 21, and enters Permanente Creek near the entry road overpass. The Pond 20
October 15, 2018 1665523002
6
area contains many BMPs including a lined inlet with multiple gabion basket check dams, flocculent logs, and
sodium bisulfite for pH correction. Water diversion speed bumps and sand bags separate process water from
industrial stormwater and minimize contact with impurities.
3.3.5 Pond 30 (Discharge Point No. 006)
Pond 30 receives stormwater from the East Materials Storage Area (EMSA) and access roads. The location of
Pond 30 and the associated catchment is provided in Figure 8. Stormwater runoff from the access road starting
near the cement plant is conveyed downslope alongside the access road and is collected in detention basins
(Ponds 31A and 31B) near the top of the slope and is conveyed via pipeline and drainage swales down to Pond
30. The operational areas around the eastern portion of the EMSA have been redirected to route flow into Pond
30. There is an outlet standpipe in Pond 30 that overflows through an underground pipe to a vault equipped with
pumps to transport the stormwater to Pond 11 (Reclaim Water System). The stormwater is then treated and
discharged via Discharge Point No. 001.
A French drain has been constructed adjacent to Pond 30 and the inlet ditch to intercept underground water flows.
This water is also collected in the vault and pumped to Pond 11 for treatment before discharge.
3.3.6 Reclaim Water System
The Reclaim Water System is a combination of industrial stormwater and process water from the Quarry, Primary
Crusher, Cement Plant, and Truck Wash. Further detail about the Reclaim Water System sources is included in
the Pollution Prevention Plan.
3.4 Locations of Exposed Industrial Activities and Industrial Materials
Significant industrial activities and materials that could be exposed to stormwater in catchment areas for
Discharge Point Nos. 002, 004, 005, and 006 include:
The locations of these activities and materials are shown on Figure 3.
3.5 Erosion Potential
The Facility is primarily unpaved, except for in the cement plant area. Erosion of non-vegetated areas can cause
sediment mobilization and increased sediment loading in stormwater discharges. Additional sources of disturbed
sediments include erosion from haul roads. Most of the drainage pathways at the Facility flow toward retention
ponds or are pumped from low lying areas into the respective retention ponds.

4.0 DESCRIPTION AND ASSESSMENT OF INDUSTRIAL ACTIVITIES AND
MATERIALS, POTENTIAL POLLUTANT SOURCES, AND
POLLUTANTS
The NPDES Permit establishes the monitoring program for stormwater and includes discharge limitations or action levels for the following potential stormwater pollutants:
Industrial activities and materials at the facility that are potential sources of these pollutants include: materials the facility mines, crushes, transports, and processes; materials storage; equipment fueling and maintenance; truck and equipment transport, repairs, maintenance, and washing; settled dust and particulate matter resulting from facility operations; and wastewater treatment.
Lehigh mines and processes limestone at the facility and produces Portland cement. Overburden and limestone that are not suitable for cement manufacturing is deposited in materials storage areas. Finished Portland cement is shipped by bulk truck or trucked in bags to offsite commercial markets. Additionally, regulated hazardous materials are stored at the facility for use in all aspects of facility operations. An HMBP for the facility has been prepared and a copy is kept onsite and provided to local enforcement agencies.
Table 2 lists materials used outside of the Reclaim Water System and Discharge Point 001 that could be potential stormwater pollutants. The table provides a summary of industrial activities where stormwater run-off could originate along with potential sources of pollutants, potential pollutants, and the BMPs to prevent pollutants from entering the stormwater discharges. (Note, the Reclaim Water System and Discharge Point 001 are included in the PPP and BMP Plan). The most likely sources of stormwater pollutants are industrial processes that result in the release of dust and particles, oil and grease, metals, and high pH liquids. Potential pollutant sources are discussed further by area and process in the following sections.
4.1 Quarry, Primary Crusher, and Cement Plant
As discussed in Section 1.0 and 3.3, the catchment areas that include stormwater from the Quarry, and Cement
Plant are not included in this SWPPP; however, dust generated from activities in these areas can migrate to other
October 15, 2018 1665523002
8
catchment areas, settle on exposed surfaces and potentially pollute stormwater. Fugitive dust emissions are controlled by implementing the Fugitive Dust Control Plan (Lehigh 2010). Also, as identified in Table 3, the Facility
frequently sweeps paved areas to remove settled dust.
4.2 Surge Pile Rock sourced from the quarry operation is stockpiled in the Surge Pile. Stormwater contacting the Surge Pile can be exposed to pollutants including TSS, high pH, settleable matter, turbidity, conductivity, and metals. Stormwater runoff is conveyed through a drainage ditch along an access road to Dinky Shed and/or Pond 20. Several rock
check dams within the ditch slow the runoff flows to reduce the particulate loading in this runoff water.
4.3 Rock Plant Equipment and Material Storage
The Facility stores inactive vehicles, tires, and equipment including process equipment in this area, which is located along the western portion of the Rock Plant. The Facility also stores aggregate material mainly at the western and southern portions of it. The equipment and material are stored outdoors and exposed to stormwater.
Stormwater in this area may be exposed to TSS, O&G, settleable matter, turbidity, conductivity, metals, visible oil, and visible color. Stormwater from this area flows to either Pond 17, Dinky Shed or Pond 20. The Facility maintains BMPs to reduce the flow velocity to reduce the amount of particles in the stormwater. As part of good housekeeping procedures outlined in Section 5.0, these materials will be removed or covered.
4.4 Rock Plant Haul Road
The haul road is located south of the Rock Plant and heads south, upslope, towards Stevens Creek Quarry.
(Figure 9). The road is graded to drain along a ditch containing check dams, on the west side of the road. About halfway down the road there is a catch basin that collects water in the ditch and discharges to a drain pipe that conveys runoff down the slope and discharges at the bottom of the slope. Conveying runoff in a pipe reduces erosion of the ditch. Exposed slopes created during construction of the road have been hydroseeded and straw wattles have been placed perpendicular to the slopes to reduce erosion and sediment migration.
4.5 EMSA
Soils and rock types not used in the cement process that are also mined are collectively described as overburden.
Overburden and any unsuitable limestone have been deposited in the EMSA according to a design described in the Quarry Reclamation Plan. Stormwater contacting the EMSA may be exposed to pollutants including TSS, high pH, settleable matter, turbidity, conductivity, and metals. Stormwater runoff from the EMSA flows through two retention ponds (Ponds 31A and 31B), drainage ditches, and culverts to Pond 30 to settle particles and reduce potential pollutants before discharge. The entire EMSA was covered with non-limestone materials and hydroseeded in 2016 to reduce the risk of stormwater exposure to limestone. EMSA has multiple rock check boxes and water bars along the roads.
As noted previously, the Pond 30 discharge is diverted to the Reclaim Water System.
4.6 Truck and Equipment Maintenance Heavy equipment and trucks are used, repaired, and maintained at the Facility. Routine fueling and maintenance are performed in specific maintenance and fueling areas that are in catchment areas not included in this SWPPP; however, repairs and maintenance can occur at any location of the facility due to equipment malfunction or due to operational constraints. Materials stored in the covered fuel and maintenance area or on the quarry service trucks that may pollute stormwater include diesel fuel, new and used motor oil, miscellaneous lubricants, hydraulic fluids,
October 15, 2018 1665523002
9
and anti-freeze. These materials are delivered to the site on an as-needed basis. The site maintains an SPCC plan in regard to spill prevention of petroleum materials, including providing SPCC procedures to third party suppliers.
Leaks and spills of oil from containers and filters during transfer operations can expose stormwater to pollutants.
Leaks and spills of oil from the tanks or drums could expose these materials to stormwater. Oil and fluid leaks
from equipment during Facility operations could expose these materials to stormwater. The potential sources of
stormwater pollutants from truck and equipment maintenance include:
4.7 Truck Washing Area
The Facility maintains wheel and vehicle washers near the Facility entrance. The washwater is collected and
pumped to the Reclaim Water System. Customer vehicles and/ or equipment pass through the washers to prevent
track-out onto public roads. Facility vehicles also pass through the washer before exiting the Facility. This area is
routinely inspected to ensure washwater is contained and properly conveyed to the Reclaim Water System.
4.8 Former Aluminum Plant Equipment Storage
In an area directly northwest of the former Aluminum Plant, the Facility stores process equipment. The equipment
is stored outdoors and is exposed to stormwater. Stormwater in this area appears to pond adjacent to the Former
Aluminum Plant and may be exposed to TSS, O&G, settleable matter, turbidity, conductivity, metals, visible oil,
and visible color.
4.9 Additional Areas
4.9.1 QC Laboratory
The Facility includes a materials testing or Quality Control (QC) Laboratory located along the northeast portion of
the site (Figure 3). Chemical storage is indoors; however, raw materials including gravel are currently stored
outdoors at the QC Laboratory Parking Lot.
4.9.2 Wastewater Treatment Plant
The Facility operates a small wastewater treatment plant to treat domestic wastewater (sewage). This plant is
permitted, and discharges effluent to a thickener tank to be used as part of the Reclaim Water System. Sodium
Hypochlorite and Chlorine tablets are stored within this plant under cover and in secondary containment. While
not anticipated to be significant in amount, any stormwater runoff from the Wastewater Treatment Plant will be
directed to the western access road and discharged through Pond 20.
4.10 Non-Stormwater Discharges
The Facility will implement measures to ensure non-stormwater process water discharges in contact with
industrial areas do not occur.
October 15, 2018 1665523002
10
5.0 BEST MANAGEMENT PRACTICES
Non-structural, or operational, BMPs generally consist of processes, prohibitions, procedures, schedule of
activities, etc., that reduce potential for exposure of stormwater discharges. The following BMPs are applicable to
Facility activities within catchments for Discharge Points Nos. 002 through 006. The Facility activities and
associated BMPs are summarized on Table 3. Additionally, as noted in Section 2.3, a separate BMP Plan will be
prepared and maintained at the Facility.
5.1 Good Housekeeping
The Facility will implement the good housekeeping BMPs described below.
Good housekeeping measures are implemented in the maintenance areas to avoid spills or leaks being tracked outside. Per the Facility’s SPCC Plan (LFR Inc. 2006), the following activities occur:
October 15, 2018 1665523002
11
Additionally, per the Reclamation Plan, the BMPs within the reclamation plan boundary are inspected during the rainy season at least once a month and after any significant rain event1.
5.2 Preventative Maintenance
The Facility implements the preventative maintenance procedures described below.
5.3 Spill and Leak, Prevention and Response
The Facility implements the spill prevention procedures described below consistent with the Facility SPCC and
HMBP.
1 Completed by facility environmental personnel, contractor personnel, or both
October 15, 2018 1665523002
12
Facility personnel properly label and use lids to seal cans and drums storing liquids and use spigots, pumps, and
funnels to dispense and transfer liquids to reduce the possibility of spills. Drip pans or other protective devices are
used for liquid transfer operations to catch incidental spillage and drips from dispensing products from drums,
barrels, or dispenser pumps. Used liquids, including petroleum hydrocarbons and coolant, are stored under cover
and within secondary containment pending removal by a hazardous waste disposal contractor. Containers of
products like paint, solvents, or cleaners are completely emptied before disposal in the solid waste garbage,
returned to the supplier, or handled as hazardous waste if not empty. Spill cleanup kits are maintained near the
material storage areas consistent with the SPCC.
If required, spills must be immediately reported to proper authorities. Reporting is required for spills of oil or
hazardous substances greater than the reportable quantities described in CFR Title 40, Parts 302.4 and 117 and
the Facility’s SPCC and HMBP. Forms for describing significant spills and leaks and recording response
procedures are included in the Facility’s SPCC and HMBP.
5.4 Material Handling and Waste Management
The following material handling and waste management procedures are implemented as described below.
Equipment leak prevention and spill cleanup procedures are discussed in Sections 5.2 and 5.3.
5.5 Fuel, Oil, Used Oil, and Antifreeze Delivery and Pickup
Fuel, oil delivery and used oil and used antifreeze pickup are attended by a Facility representative. The lowermost
drain and outlets of delivery vehicles are inspected for evidence of leakage prior to filling and prior to
departure. The ground surface is inspected for spills and drips and corrective action is taken as needed. The
drains and outlets are tightened, adjusted, or replaced to prevent liquid discharge while in transit. If a spill due to a
hose connection/equipment failure were to occur, the spilled material would be contained using spill kit material,
and the resulting contaminated clean-up materials would be transferred to a storage container for off-site disposal.
These procedures as well as a notification to vendors providing these services are included in the Facility’s SPCC
plan.
October 15, 2018 1665523002
13
5.6 Leakage of Oil from Stored Equipment and Vehicles
Occasionally fuel, hydraulic oil, or engine oil may drip from stored vehicles and equipment. Any such leakage
should be identified during daily inspection of the Facility and reported to the Stormwater Team Leader so that
corrective actions can be taken to:
5.7 Equipment/Vehicle Fueling
Equipment and vehicle fueling activities have the potential to contribute spillage of gasoline or diesel fuel. To
ensure this activity does not contribute to hydrocarbon contamination of stormwater, the following BMPs are
implemented and these activities are performed consistent with the Facility’s SPCC:
5.8 Erosion and Sediment Control
The majority of the Facility ground surface is unpaved. To prevent soil erosion and sediment transport in
stormwater, the Facility implements the erosion and sediment control procedures described below to the extent
practicable.
5.9 Employee Training Program
The Facility implements the employee training program procedures described below and consistent with the
SPCC and HMBP.
October 15, 2018 1665523002
14
The Facility has an established training program. The PPT will provide annual training for current and future
employees. The PPT will provide training for new employees within 30 days. This training will include good
housekeeping procedures, preventive maintenance, spill prevention and response, BMP maintenance, and record
keeping.
Facility employees that have direct responsibilities in areas of the Facility that have the potential to impact
stormwater will receive SWPPP training annually. More frequent training will be conducted as necessary to
address employee turnover. All PPT and employee training is to be documented and the records will be stored
with the SWPPP. Records of employee training are to be kept for at least 5 years. Employee training records may
be kept on the form provided in Appendix B.
5.10 Quality Assurance and Record Keeping
The Facility implements the quality assurance and record keeping procedures described below.
The PPT or plant manager is responsible for ensuring that all elements of the SWPPP are implemented, that BMP
implementation is tracked and recorded, and that all records required by the NPDES Permit and SWPPP are
maintained for a minimum of 5 years. Quality assurance activities undertaken will be documented and entered
into the SWPPP records.
6.0 ADVANCED STRUCTURAL, SOURCE CONTROL, AND TREATMENT
BMPS
Structural BMPs are to be considered when non-structural BMPs have been ineffective. Structural BMPs consist
of structural devices that reduce or prevent pollutants in stormwater discharges. Examples include:
discharged from the site
The following structural controls are implemented at the Facility.
6.1 Overhead Coverage
The Facility stores petroleum products and other fluids and materials associated with equipment maintenance
under cover to the extent practicable. This overhead coverage reduces or prevents the potential for stormwater
pollutants associated with these activities from contacting or entering stormwater. These potential pollutants
include TSS, O&G, metals, and visible oil.
6.2 Stormwater Detention Basins
Several stormwater detention basins are located at the Facility: Pond 9, Pond 13B, Pond 17, Pond 30, Pond 31A,
Pond 31B, and SB-7. The locations of the stormwater detention basins are shown on Figure 3 and more detailed
views are shown on Figures 4 through 9. Pond 20, given its configuration as a drainage throughput, and not a
traditional “pond,” and does not contain freeboard necessary to accomplish retention of stormwater flows.
Detention basins allow particulates to settle before stormwater is discharged. Potential pollutants mitigated by the
retention basins include TSS, settleable matter, turbidity, conductivity, and metals. Annual sediment removal from
these basins should be performed to maintain retention capacity and reduce potential pollutant exceedances
associated with particulates.
6.3 Particle Filtration
The Facility implemented BMPs to aid in the filtration of stormwater runoff. For example, several gravel check
dams were installed along Discharge Point No. 005 drainage to promote filtering of the stormwater prior to
discharge.
6.4 Secondary Containment
The Facility uses secondary containment for the storage of petroleum products and other fluids and materials
associated with equipment maintenance and hazardous materials. The secondary containment reduces or
prevents the potential exposure of these materials to stormwater.
6.5 Advanced Erosion and Sediment Control
Activities that generate the potential for erosion and sediment migration include transport and storage of
limestone, unsuitable limestone, and overburden rock and soil. Operations at the site expose slopes and access
roads to erosion. Erosion or sediment controls are generally commenced as soon as practicable following
completion of soil/ rock disturbing activities. The storm water drainage systems in place have been designed to
divert storm water away from operational areas and to stormwater retention basins.
Specific narrative descriptions of BMPs that are implemented at the Facility, to the extent practicable, are listed by
category in each of the following sections. Additionally, a copy of the California Stormwater Quality Association
(CASQA) BMP Handbook fact sheets for erosion and sediment control BMPs for implementation guidance and
reference is attached as Appendix C.
October 15, 2018 1665523002
16
6.5.1 Erosion Control
Erosion control, also referred to as soil stabilization, consists of source control measures that are designed to
prevent soil particles from detaching and becoming transported in stormwater runoff. Erosion control BMPs
protect the soil surface by covering and/or binding soil particles. The Facility will incorporate erosion control
measures that are effective and result in the reduction of sediment related pollutants in stormwater discharges.
The Facility will implement the following practices for effective temporary and longer-term erosion control during
soil disturbing activities:
Sufficient erosion control materials will be maintained on-site to allow implementation in conformance with the
SWPPP. This includes implementation of BMPs in active areas and non-active areas before the onset of rain.
The BMPs that should be considered for implementation to prevent erosion include:
October 15, 2018 1665523002
17
6.5.2 Sediment Control
Sediment controls are structural measures that are intended to complement and enhance the selected erosion
control measures and reduce sediment discharges from disturbed soil areas. Sediment controls are designed to
intercept and settle out or filter soil particles that have been detached and transported by the force of water.
Sufficient quantities of temporary sediment control materials will be maintained on-site to allow implementation of
temporary sediment controls in the event of predicted rain and for rapid response. This includes implementation
requirements of BMPs in active areas and non-active areas that require deployment before the onset of rain. The
BMPs that should be considered for implementation to prevent sediment migration from disturbed soil areas
include:
7.0 MONITORING AND REPORTING PROGRAM
The monitoring and reporting program (MRP) is provided in Attachment E to the NPDES Permit. The NPDES
Permit Section VI.C.6.a includes requirements for this SWPPP and an annual report. According to VI.C.6.b, the
Annual Stormwater Report must be submitted by July 1 providing data for the previous wet weather season. The
Annual Stormwater Report will include, at a minimum, the following:

Subject: Annual Reclamation Plan Amendment Activities Greenhouse Gas Inventory
Annual analysis of the Greenhouse Gas Emissions (GHG) associated with Reclamation Plan
Amendment activities at the Lehigh Southwest Cement Company’s Permanente Quarry
(Quarry) in Santa Clara County, California. This inventory is pursuant to Conditions of Approval
(COA) 71, 72, and 73 of the 2012 Reclamation Plan Amendment, for the reporting period of July
1, 2018 through June 30, 2019.
Methods and Thresholds
The methodology used in this memo to analyze the project’s contribution to global climate
change includes a calculation of GHG emissions associated with Reclamation Plan Amendment
Activities, beyond baseline levels as described in the EIR1, and a comparison of GHG emissions
with the thresholds set forth in the COA. GHG emission would be considered significant and
require mitigation if they exceed 1,100 metric tons of Carbon Dioxide equivalent (CO2e) within a
year. Reclamation Plan Amendment activities included, but not limited to, the following:
• Reclamation of slope, grading, and hauling of materials
• Maintenance of erosion control features
• Hydroseeding activities
• Sediment basin maintenance
The Bay Area Air Quality Management District (BAAQMD) recommends use of the California
Emissions Estimator Model™ (CalEEMod) to estimate GHG emissions associated with
construction of individual development projects and operational GHG emissions.2 CalEEMod is
a statewide land use emissions computer model designed to provide a uniform platform for
government agencies, land use planners, and environmental professionals to quantify potential
criteria pollutant and GHG emissions associated with both construction and operations from a
variety of land use projects.3 The mobile source emission factors used in the model
(EMFAC2011) includes the Pavley standards and Low Carbon Fuel standards into the mobile

source emission factors. The model was developed in collaboration with the air districts of
California. Default data (e.g., emission factors, trip lengths, meteorology, source inventory, etc.)
have been provided by the various California air districts to account for local requirements and
conditions.
GHG emissions associated with the projects were modeled using CalEEMod version 2013.2.2
using general project information provided to WRA. Project inputs and assumptions are
summarized in the Table 1 below.
Table 1. Off-Road Reclamation Activities Diesel Equipment
Greenhouse Gas Inventory Results
An inventory of reclamation activity emissions was taken for the period of July 1, 2018 through
June 30, 2019. Total emissions for the study period were 688.34 metric tons of CO2e. Emissions
were below the threshold of 1,100 metric tons of CO2e as set in COA 71. Therefore, no offset or
additional actions are required to mitigate for GHG emissions.

Subject: Improved Reclamation Plan Boundary Demarcation
In order to maintain compliance with Santa Clara County Final Conditions of Approval number
22, the T-posts that served to demarcate the EMSA, WMSA, and Rock Plant Reclamation Plan
Amendment (RPA) Boundaries were repainted with high visibility orange spray paint. This was
done to improve the visibility of the demarcation boundary (see Demarcation Maps, Figures 1-
3).
Conditions of Approval Requirements
Conditions of Approval (COA) number 22 of the Santa Clara County Final Conditions of
Approval specify the measures to be taken to maintain the demarcation of the EMSA, WMSA,
and Rock Plant Reclamation Plan Amendment Boundary.
The relevant COA is summarized below:
COA 22. Maintain Demarcation of EMSA, Rock Plant, and WMSA RPA Boundaries.
Within 60 days of RPA approval, the RPA limit of disturbed area surrounding the
northern and eastern edges of the EMSA, the northern and western edges of the
WMSA, and the perimeter of the Rock Plant area shall be clearly demarcated in the field
and shall remain in place until final reclamation has been completed. On an annual
basis, demarcation shall be modified to encompass the RPA boundaries nearest the
areas subject to surface mining and reclamation, as shown on aerials submitted per
Condition number 23. Demarcated areas shall be located and marked in the field by a
licensed land surveyor or registered civil engineer authorized to practice land surveying.
Demarcation shall use orange construction fencing or other brightly colored material
acceptable to the Planning Manager.
EMSA, Rock Plant, and WMSA RPA Boundary Demarcation Improvements
On July 24, 2019 Lehigh repainted the existing T-post markers, which demarcated the EMSA,
Rock Plant, and WMSA RPA boundaries. The T-posts were painted with high visibility orange
paint. The demarcation boundary did not move as quarry activities are not planned in or near
those areas and there are no plans in place to go beyond the demarcation line. Additional
Memo to: Tressa Jackson
09-23-2019
Page 2
markers were not needed in other areas because future quarry activities are not scheduled to
be located near other portions of the RPA boundary.
Summary
In order to maintain compliance with COA 22, improvements to the durability and visibility of the
RPA Boundary were made by repainting the existing T-posts. All T-posts were observed to be
standing in the exact locations as when they were placed.
Per the Final Conditions of Approval, all requirements for maintaining the demarcation of the
EMSA, Rock Plant, and WMSA RPA Boundaries have been met.

(i.e., increase of disturbed acres, increase of depth, increases in amount of equipment and/or facilities, required corrective actions, etc.)
Current operations at the site include a quarry (Main Pit/North Quarry) that consists of a cut-face with
a series of benches and multiple material storage areas – East Material Storage Area (EMSA) and
West Material Storage Area (WMSA). Reclamation at the quarry is conducted on an annual basis for
areas at final grade and not subject to further disturbance. In 2012, reclamation work commenced in
the Permanente Creek Reclamation Area (PCRA), the installation of BMP’s and hydroseeding was
completed in Subareas 4, 5 and 6. Current grading activities are taking place in Phase 1A of the
approved mine plan. The majority of the 639.6-acre RPA footprint is found in a fully disturbed
condition with little evidence of vegetative cover. An exception to this includes areas where
reclamation has begun or areas that have naturally revegetated. In total, approximately 546 acres are
currently disturbed at the site. There is also a rock plant, cement plant, and various pieces of mobile
equipment on the site.
It is expected that mining will continue to progress in Phase 1 of the Main Pit during the next 12
months.
The total cost has increased as a result of pipeline removal costs that were added to this year’s
estimate and increased labor, equipment, and revegetation costs.

At this time, plant removal would involve demolishing and transporting the Rock Plant, including
conveyors, crushers, screens, wash plants, scales, storage tanks, and miscellaneous structures to an
offsite location. This also includes the removal of the overland conveyor that extends from the Main
Pit to the Cement Plant (approx. 8,900 feet). In addition to demolition and removal of these structures,
all foundations must be demolished and removed, and compacted surfaces must be ripped to prepare
the site for revegetation.
At the conclusion of mining operations, all equipment, structures, and other infrastructure
improvements will need to be removed from the site.
This estimate assumes the use of a crane, excavators with steel shear and grapple attachments, frontend
loaders, trucks with low bed trailers, and dump trucks for dismantling and removing the plant
equipment and structures. The steel structures will be cut into manageable pieces with an excavator
mounted with a steel shear, with pieces placed on an over-the-road truck for removal to a scrap yard
for recycling. It is estimated that there is approximately 1,000 tons of recyclable steel onsite. Current
market value of scrap steel is $160 per ton (Alco Metals, San Jose). Other non-recyclable materials
will be put into roll-off dumpsters (CDR Dumpster Rental) and hauled off site. Some structures will be
dismantled by shearing, cutting using a cutting torch, or simply unbolting the equipment from the
support structures prior to demolition. Also, there are currently 30 pieces of mobile equipment
(loaders, dozers, trucks, etc.) that would need to be loaded and hauled off site to a resale dealer. This
estimate assumes two (2) hours per piece of equipment. Once the equipment is removed, it will be
necessary to demolish all concrete footings and foundations. Concrete will be broken up using an
excavator and a hydraulic hammer and hauled to a recycling yard. This estimate assumes that there
is approximately 2,950 cubic yards of concrete to be demolished and removed from the site. Also,
approximately 28,110 linear feet of water pipeline will need to be dismantled and removed from the
site.

Backfilling Main Pit
Current Site Conditions:
VI. PRIMARY RECLAMATION ACTIVITY :
Use multiple sheets as necessary to estimate the cost of each activity required. Provide documentation showing that rates, prices, and wages are available
locally to the lead agency and/or the Department if necessary.
Provide Quantities:
Overburden and topsoil, cut and fill, import or export (cubic yards), area (acres), haul distance (feet), equipment production rates (cubic
yards/hour, or as applicable), etc.
Describe tasks, methods, equipment, etc:
Decompaction, cut, fill, haul, slope reduction, compaction, grading, topsoil placement, drainage work, soil amendment, special requirements,
etc. Separate sheets may be used for each task if necessary.
Reclamation Plan Performance Standard (End Use):
This estimate’s restoration scenario incorporates backfilling of the Main Pit to buttress past
instabilities. To accomplish this, the West Materials Storage Area (WMSA) will be used as the primary
source of backfill material, since mining byproducts (unused mined material) will not be available. A
stockpile located west of the Rock Plant, that contains approximately 300,000 tons of crushed rock,
will also be relocated to the main pit. Material used for backfilling is to be amended with organic
matter (approximately 63,000 tons). Measures to protect surface water quality during reclamation
activities consist of isolating runoff from limestone materials in the Main Pit backfill, WMSA, and
EMSA. This will be accomplished during reclamation by capping reclaimed areas with a 1-foot thick
layer of run-of-mine non-limestone rock (i.e., greywacke, chert, and greenstone).
Reclamation requirements for the site include the development of a benched quarry face with an
overall slope gradient of 1H:1V (horizontal: vertical), while the overburden fill slopes will be reclaimed
at a maximum overall slope inclination between 2.5H:1V to 2.6H:1V. The proposed end use for the
quarry after reclamation is complete is open space.
A conveyor system will be utilized to transport backfill material from the WMSA to the Main Pit and
place material directly into the pit. Oversized material will be reduced by a jaw crusher to six (6) inch
minus prior to loading onto the conveyor. This estimate assumes the purchase of a crusher,
conveyor, and stacking system (See Attachment 1 for cost estimate). Operation and maintenance
costs to run the system have been included in the tables below. Stockpiled material near the Rock
Plant will be relocated to the Main Pit by using haul trucks that are loaded with a front-end loader.
Organic material would be delivered to the WMSA from an offsite source and added to backfill material
with a loader. Distribution of non-limestone material for capping will utilize a variety of equipment. A
combination of dozers, scrapers, loaders, and haul trucks will be utilized to distribute the nonlimestone
capping material.
After analyzing the existing and proposed topography, the total volume required for backfilling the Main
Pit is estimated at 29,845,648 cubic yards (See Attachment 2 for volume estimate memo from Stantec
Consulting Services, Inc.). This volume accounts for material that was removed from the pit during the
past year (846,773 cubic yards). During the past year, most mining activity occurred in the southern
portion of the Main Pit. The conveyor system would extend approximately 10,000 feet to the WMSA.
Backfilling of the Main Pit will also include grading of approximately 6,700,000 cubic yards of nonlimestone
material that has been identified as the “Main Slide.” Materials originating from the Main
Slide will be removed using a D10 bull dozer (See Attachment 3 for production rates). This estimate
assumes production rates of 1,027.5 cubic yards per hour for the D11 bulldozer and 1,380 cubic yards
per hour for the conveyor system. To optimize production from the dozers, the conveyor system will
be relocated as grading progresses; average push distances will be kept at approximately 300 feet.
For stockpiled material near the Rock Plant, a Cat 992 front-end-loader will load the material into haul
trucks while a water truck and grader will be utilized to maintain the road network and suppress dust.
It is estimated that there is 200,000 cubic yards of stockpiled material (using 1.5 tons per CY). Organic
material would be delivered by trucks to the WMSA, near the hopper for the portable conveyor system,
and a 938 loader will feed the material into the hopper. Approximately 710,000 cubic yards of nonlimestone
material will be used for capping reclaimed areas of the site. Caterpillar production rates for
a 651 Scraper are provided in Attachment 4.

Permanente Creek Reclamation Area
This section describes the reclamation costs of historic mining disturbance adjacent to Permanente
Creek, described as the Permanente Creek Reclamation Area (“PCRA”). The PCRA is divided into
seven different subareas (numbered one through seven) with customized reclamation treatments for
each subarea. In 2012, after approval of the RPA, reclamation work commenced in Subareas 4, 5
and 6 and was completed in late October. Work completed included installation of BMPs as well as
hydroseeding of disturbed areas. In total, approximately nine (9) acres in the PCRA was reclaimed in
2012. In 2016, the application for permitting the restoration work with ACOE and CDFW was
submitted and is in process.
Removing a concrete half culvert located in the proposed restored stream channel is one aspect of the
Permanente Creek Restoration. The concrete half culvert is located just downstream from Pond 13
and covers a length of approximately 375 feet. The reclamation plan also calls for restoration of about
2,500 linear feet of Permanente Creek. Material from historic mining has collected in the creek
channel. The reclamation plan calls for removal of this material and creation of a reconfigured creek
channel that is roughly 50 feet wide with a 10-foot bottom and 3:1 side slopes. A number of limestone
boulders have found their way into Permanente Creek as a result of historic mining operations. These
boulders range in size from approximately 10″ to 3′ in diameter. Once removed from the creek,
boulders will be loaded onto off-road haul trucks and hauled to the North Quarry for final placement.
After grading work has been completed and prior to revegetating the site temporary and permanent
BMPs will be installed to manage stormwater runoff. Lastly, slopes located in Subareas 2 and 3 of the
PCRA are comprised of loose unconsolidated fill material. In an effort to reduce erosion from these
slopes and to provide more favorable surfaces for seed propagation, the slopes will be compacted.
According to the CAT Handbook, an H120c hydraulic hammer attached to a 315L excavator can
demolish approximately 230 cubic yards of reinforced concrete within 8 hours. Once the concrete
culvert has been broken into pieces 2-feet in diameter or smaller, the excavator will be used to load
the material into haul trucks. Material will be removed from the creek with an excavator, loader, and
articulated haul trucks. Small boulders will be removed using hand labor, while larger boulders will be
removed with an excavator and/or loader. Construction laborers will install straw waddles and silt
fencing to manage stormwater runoff. Slopes located within Subareas 2 and 3 will be compacted with
a D8 dozer, towing a sheep’s foot, that is moved up and down the slopes by a winch.
It is estimated that approximately 130 cubic yards of concrete will need to be demolished and removed
to complete removing the concrete half culvert. There is an estimated 17,500 cubic yards of material
that will be removed from the channel to create the reconfigured channel. This estimate also assumes
that 200 boulders are located within the inundation limits of Permanente Creek.

Provide documentation showing that rates, prices, and wages are available locally to the lead agency and/or the Department.
(add additional pages as needed)
After final grading is completed, disturbed areas of the site will be revegetated with seed mixes and
container stock to achieve the goals of the reclamation plan. Previous restoration planting at the
Quarry has been used as a guide for revegetation planning. Also, approximately 2 acres were
hydroseeded near the Rock Plant during the past year. These revegetated areas will serve as a basis
for anticipated revegetation success. Native species common in revegetated areas include California
buckwheat, coyote brush, buckbrush and sagebrush. At this time, 13.7 acres of hydroseeding would
be necessary within the PCRA and 502 acres of hydroseeding would be required on the remaining
areas of the site. An additional 1.5 acres of the PCRA and 28 of the remaining reclamation area will
require hand planting of container stock.
The goal for revegetation efforts is native community restoration. This refers to the reclamation of
disturbed lands to a self-sustaining community of native species which would visually integrate with
surrounding lands. Revegetation is designed to control erosion and stabilize slopes against long-term
erosion using plant materials capable of self-regeneration without continued dependence on irrigation,
soil amendments or fertilizer.
Prior to revegetation, growth medium will be applied to approximately 498 acres of the site. Of the
498 acres that will receive growth medium, a thickness of six inches of topsoil will be distributed over
28 acres of the site and a thickness of three inches of topsoil will be distributed over 470 acres for a
total volume of 212,152 CY. To transport the material around the site, a team of off-road haul trucks
will be utilized and D8 dozer will be used to spread the material. A dozer is preferred to distribute the
topsoil over a wheel type tractor because its track impressions will imprint final slopes to retain seeds
and increase water retention and infiltration, thereby increasing the potential for revegetative success.
Using mechanical hydroseeding equipment, areas will be seeded, mulched, and composted in a single
application. A hydromulch mix will contain compost, organic mulch, fertilizer and the seed mix. See
Attachments 5 and 6 for seed quotes from Pacific Coast Seed. Freedlun Hydroseeding provided a
conservative cost quote for the hydroseed applications (Attachment 7). Planting shrubs and trees will
require the efforts of four common laborers and two pickup trucks along with the oversight of a
revegetation specialist.

Prices and deliveries are all over the place. In general factories are somewhat busy with reduced staff, handing
one project at a time. There is no consistency in the market. This being said we realize this is a long term
project; currently complete shipment would be accomplished in a 6 – 8 month period.
Our invoice EQ16118 for services in relation to this project is attached.
We trust this meets your requirements and that you will not hesitate in contacting us if you need additional
information.
Very truly yours,

Example problem:
Determine average hourly production of a D8T/8SU
(with tilt cylinder) moving hard-packed clay an average
distance of 45 m (150 feet) down a 15% grade,
using a slot dozing technique.
Estimated material weight is 1600 kg/Lm3
(2650 lb/LCY). Operator is average. Job efficiency
is estimated at 50 min/hr.
Uncorrected Maximum Production — 458 Lm3/h
(600 LCY/hr) (example only)
Applicable Correction Factors:
Hard-packed clay is “hard to cut” material –0.80
Grade correction (from graph) . . . . . . . . . .–1.30

Average operator . . . . . . . . . . . . . . . . . . . . .–0.75
Job efficiency (50 min/hr) . . . . . . . . . . . . . .–0.83
Weight correction . . . . . . . . . . .(2300/2650)–0.87

To obtain production in metric units, the same
procedure is used substituting maximum uncorrected
production in Lm3.

I. FACILITY INFORMATION
Information describing the Lehigh Southwest Cement Company’s (Discharger’s) Permanente Plant
(Facility) is summarized in Table 1 and Fact Sheet (Attachment F) sections I and II.
II. FINDINGS
The California Regional Water Quality Control Board, San Francisco Bay Region (Regional Water
Board), finds the following:
A. Legal Authorities. This Order serves as WDRs pursuant to California Water Code article 4,
chapter 4, division 7 (commencing with § 13260). This Order is also issued pursuant to federal
Clean Water Act (CWA) section 402 and implementing regulations adopted by U.S. EPA, and
Water Code chapter 5.5, division 7 (commencing with § 13370). It shall serve as a National
Pollutant Discharge Elimination System (NPDES) permit authorizing the Discharger to
discharge into waters of the United States as listed in Table 2 subject to the WDRs in this Order.
B. Background and Rationale for Requirements. The Regional Water Board developed the
requirements in this Order based on information the Discharger submitted as part of its
application, information obtained through monitoring and reporting programs, and other
available information. The Fact Sheet (Attachment F) contains background information and
rationale for the requirements in this Order, and is hereby incorporated into and constitutes
findings for this Order. Attachments A through E, G, and S are also incorporated into this Order.
C. Provisions and Requirements Implementing State Law. No provisions and requirements in
this Order are included to implement State law only.
D. Cease and Desist Order. The Regional Water Board adopted Cease and Desist Order
No. R2-2014-0011 (later amended through Order No. R2-2017-0031) to enforce foreseeable
violations of Order No. R2-2014-0010 (later amended through Order No. R2-2017-0030)
(previous order). The Cease and Desist Order required full compliance with the previous order
by October 1, 2017, and this Order rescinds the previous order. Therefore, the Cease and Desist
Order is no longer needed and can be rescinded.
E. Technical Information Requirement. On August 1, 2018, the Executive Officer ordered the
Discharger to provide technical information about Facility discharges and their effects on
Permanente and Stevens creeks pursuant to Water Code section 13267. The Monitoring and
Reporting Program (MRP) (Attachment E) incorporates and updates those information
requirements; therefore, the August 1, 2018, order is no longer needed and can be rescinded.
F. Notification of Interested Parties. The Regional Water Board notified the Discharger and
interested agencies and persons of its intent to prescribe these WDRs and rescind the Cease and
Desist Order, and provided an opportunity to submit written comments and recommendations.
The Fact Sheet provides details regarding the notification.
G. Consideration of Public Comment. The Regional Water Board, in a public meeting, heard and
considered all comments pertaining to the discharge. The Fact Sheet provides details regarding
the public hearing.

analyses.
2. Effluent Characterization Study and Report
a. Study Elements. The Discharger shall characterize and evaluate the discharges from
Discharge Point Nos. 001 and 007, as required by the MRP, to verify that the reasonable
potential analysis conclusions of this Order remain valid and to inform the next permit
reissuance.
The Discharger shall evaluate on an annual basis if concentrations of any of the priority
pollutants listed in Attachment G, Table B, significantly increase over past performance.
The Discharger shall investigate the cause of any such increase. The investigation may
include, but need not be limited to, an increase in monitoring frequency, monitoring of
process streams, and monitoring of influent sources. The Discharger shall establish
remedial measures addressing any increase resulting in reasonable potential to cause or
contribute to an excursion above applicable water quality criteria. This requirement may
be satisfied by including the constituent in the Discharger’s Pollutant Minimization
Program, described in Provision VI.C.3.
b. Reporting Requirements
i. Routine Reporting. The Discharger shall report the identity of pollutants detected at
or above applicable water quality criteria (see Fact Sheet Table F-6 for the criteria) in
the transmittal letter for the self-monitoring report associated with the month in which
samples were collected.
ii. Annual Reporting. The Discharger shall summarize the data evaluation and source
investigation in the annual self-monitoring report.
3. Pollutant Minimization Program
a. The Discharger shall develop and conduct a Pollutant Minimization Program as further
described below when there is evidence that a priority pollutant is present in the effluent
above an effluent limitation (e.g., sample results reported as detected but not quantified
[DNQ] when the effluent limitation is less than the method detection limit [MDL],
sample results from analytical methods more sensitive than those methods required by
this Order, presence of whole effluent toxicity, health advisories for fish consumption, or
results of benthic or aquatic organism tissue sampling) and either:
i. A sample result is reported as DNQ and the effluent limitation is less than the
Reporting Level (RL); or
ii. A sample result is reported as not detected (ND) and the effluent limitation is less
than the MDL using definitions in Attachment A and reporting protocols described in
the MRP.

Pollutant Minimization Program shall include, but not be limited to, the following actions
and submittals:
i. Annual review and semi-annual monitoring of potential sources of the reportable
priority pollutants, which may include fish tissue monitoring and other bio-uptake
sampling, or alternative measures when source monitoring is unlikely to produce
useful analytical data;
ii. Quarterly monitoring for the reportable priority pollutants in the influent to the
Facility. The Executive Officer may approve alternative measures when influent
monitoring is unlikely to produce useful analytical data;
iii. Submittal of a control strategy designed to proceed toward the goal of maintaining

Attachment A – Definitions A-1
ATTACHMENT A – DEFINITIONS
A
Arithmetic Mean (μ)
Also called the average, the sum of measured values divided by the number of samples. For ambient
water concentrations, the arithmetic mean is calculated as follows:
Arithmetic mean = μ = Σx / n where: Σx is the sum of the measured ambient water
concentrations, and n is the number of samples.
Average Monthly Effluent Limitation (AMEL)
The highest allowable average of daily discharges over a calendar month, calculated as the sum of all
daily discharges measured during a calendar month divided by the number of daily discharges measured
during that month.
Average Weekly Effluent Limitation (AWEL)
The highest allowable average of daily discharges over a calendar week (Sunday through Saturday),
calculated as the sum of all daily discharges measured during a calendar week divided by the number of
daily discharges measured during that week.
Bioaccumulative
Taken up by an organism from its surrounding medium through gill membranes, epithelial tissue, or
from food and subsequently concentrated and retained in the body of the organism.
Carcinogenic
Known to cause cancer in living organisms.
Coefficient of Variation
Measure of data variability calculated as the estimated standard deviation divided by the arithmetic
mean of the observed values.
Daily Discharge
Either: (1) the total mass of the constituent discharged over the calendar day (12:00 am through
11:59 pm) or any 24-hour period that reasonably represents a calendar day for purposes of sampling
(as specified in the permit) for a constituent with limitations expressed in units of mass; or (2) the
unweighted arithmetic mean measurement of the constituent over the day for a constituent with
limitations expressed in other units of measurement (e.g., concentration).
The daily discharge may be determined by the analytical results of a composite sample taken over the
course of one day (a calendar day or other 24-hour period defined as a day) or by the arithmetic mean of
analytical results from one or more grab samples taken over the course of the day.
For composite sampling, if 1 day is defined as a 24-hour period other than a calendar day, the analytical
result for the 24-hour period is considered the result for the calendar day in which the 24-hour period
ends.
Detected, but Not Quantified (DNQ)
Sample result less than the RL, but greater than or equal to the laboratory’s MDL. Sample results
reported as DNQ are estimated concentrations.
Dilution Credit
Amount of dilution granted to a discharge in the calculation of a water quality-based effluent limitation,
based on the allowance of a specified mixing zone. It is calculated from the dilution ratio or determined
by conducting a mixing zone study or modeling the discharge and receiving water.
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment A – Definitions A-2
Effluent Concentration Allowance (ECA)
Value derived from the water quality criterion/objective, dilution credit, and ambient background
concentration that is used, in conjunction with the CV for the effluent monitoring data, to calculate a
long-term average (LTA) discharge concentration. The ECA has the same meaning as wasteload
allocation (WLA) as used in U.S. EPA guidance (Technical Support Document for Water Quality-based
Toxics Control, March 1991, second printing, EPA/505/2-90-001).
Enclosed Bay
Indentation along the coast that encloses an area of oceanic water within a distinct headlands or harbor
works. Enclosed bays include all bays where the narrowest distance between the headlands or outermost
harbor works is less than 75 percent of the greatest dimension of the enclosed portion of the bay.
Enclosed bays include, but are not limited to, Humboldt Bay, Bodega Harbor, Tomales Bay, Drake’s
Estero, San Francisco Bay, Morro Bay, Los Angeles-Long Beach Harbor, Upper and Lower Newport
Bay, Mission Bay, and San Diego Bay. Enclosed bays do not include inland surface waters or ocean
waters.
Estimated Chemical Concentration
Concentration that results from the confirmed detection of the substance below the ML value by the
analytical method.
Estuaries
Waters, including coastal lagoons, located at the mouths of streams that serve as areas of mixing for
fresh and ocean waters. Coastal lagoons and mouths of streams that are temporarily separated from the
ocean by sandbars are considered estuaries. Estuarine waters are considered to extend from a bay or the
open ocean to a point upstream where there is no significant mixing of fresh water and seawater.
Estuarine waters include, but are not limited to, the Sacramento-San Joaquin Delta, as defined in Water
Code section 12220, Suisun Bay, Carquinez Strait downstream to the Carquinez Bridge, and appropriate
areas of the Smith, Mad, Eel, Noyo, Russian, Klamath, San Diego, and Otay rivers. Estuaries do not
include inland surface waters or ocean waters.
Inland Surface Waters
All surface waters of the state that do not include the ocean, enclosed bays, or estuaries.
Instantaneous Maximum Effluent Limitation
Highest allowable value for any single grab sample or aliquot (i.e., each grab sample or aliquot is
independently compared to the instantaneous maximum limitation).
Instantaneous Minimum Effluent Limitation
Lowest allowable value for any single grab sample or aliquot (i.e., each grab sample or aliquot is
independently compared to the instantaneous minimum limitation).
Maximum Daily Effluent Limitation (MDEL)
Highest allowable daily discharge of a pollutant, over a calendar day (or 24-hour period). For pollutants
with limitations expressed in units of mass, the daily discharge is calculated as the total mass of the
pollutant discharged over the day. For pollutants with limitations expressed in other units of
measurement, the daily discharge is calculated as the arithmetic mean measurement of the pollutant over
the day.
Median
Middle measurement in a set of data. The median of a set of data is found by first arranging the
measurements in order of magnitude (either increasing or decreasing order). If the number of
measurements (n) is odd, then the median = X(n+1)/2. If n is even, then the median = (Xn/2 + X(n/2)+1)/2
(i.e., the midpoint between n/2 and n/2+1).

PERMANENTE PLANT NPDES No. CA0030210
Attachment A – Definitions A-3
Method Detection Limit (MDL)
Minimum concentration of a substance that can be reported with 99 percent confidence that the
measured concentration is distinguishable from method blank results, as defined in in 40 C.F.R.
part 136, Appendix B.
Minimum Level (ML)
Concentration at which the entire analytical system gives a recognizable signal and acceptable
calibration point. The ML is the concentration in a sample that is equivalent to the concentration of the
lowest calibration standard analyzed by a specific analytical procedure, assuming that all the method
specified sample weights, volumes, and processing steps have been followed.
Mixing Zone
Limited volume of receiving water allocated for mixing with a wastewater discharge where water
quality criteria can be exceeded without causing adverse effects to the overall water body.
Not Detected (ND)
Sample results less than the laboratory’s MDL.
Persistent Pollutants
Substances for which degradation or decomposition in the environment is nonexistent or very slow.
Pollutant Minimization Program
Program of waste minimization and pollution prevention actions that include, but are not limited to,
product substitution, waste stream recycling, alternative waste management methods, and education of
the public and businesses. The goal of the Pollutant Minimization Program is to reduce all potential
sources of a priority pollutant through pollutant minimization (control) strategies, including pollution
prevention measures as appropriate, to maintain the effluent concentration at or below the water qualitybased
effluent limitation. Pollution prevention measures may be particularly appropriate for persistent
bioaccumulative priority pollutants where there is evidence that beneficial uses are being impacted. Cost
effectiveness may be considered when establishing the requirements of a Pollutant Minimization
Program. The completion and implementation of a Pollution Prevention Plan, if required pursuant to
Water Code section 13263.3(d), is considered to fulfill Pollutant Minimization Program requirements.
Pollution Prevention
Any action that causes a net reduction in the use or generation of a hazardous substance or other
pollutant that is discharged into water and includes, but is not limited to, input change, operational
improvement, production process change, and product reformulation (as defined in Water Code section
13263.3). Pollution prevention does not include actions that merely shift a pollutant in wastewater from
one environmental medium to another environmental medium, unless clear environmental benefits of
such an approach are identified to the satisfaction of the State Water Board or Regional Water Board.
Reporting Level (RL)
ML (and its associated analytical method) chosen by the Discharger for reporting and compliance
determination from the MLs included in this Order, including an additional factor if applicable as
discussed herein. The MLs included in this Order correspond to approved analytical methods for
reporting a sample result that are selected by the Regional Water Board either from SIP Appendix 4 in
accordance with SIP section 2.4.2 or established in accordance with SIP section 2.4.3. The ML is based
on the proper application of method-based analytical procedures for sample preparation and the absence
of any matrix interferences. Other factors may be applied to the ML depending on the specific sample
preparation steps employed. For example, the treatment typically applied in cases where there are
matrix-effects is to dilute the sample or sample aliquot by a factor of ten. In such cases, this additional
factor must be applied to the ML in the computation of the RL.

Source of Drinking Water
Any water designated as having a municipal or domestic supply (MUN) beneficial use.
Standard Deviation (σ)
Measure of variability calculated as follows:
where:
x is the observed value;
μ is the arithmetic mean of the observed values; and
n is the number of samples.
Toxicity Reduction Evaluation (TRE)
Study conducted in a step-wise process designed to identify the causative agents of effluent or ambient
toxicity, isolate the sources of toxicity, evaluate the effectiveness of toxicity control options, and then
confirm the reduction in toxicity. The first steps of the TRE consist of the collection of data relevant to
the toxicity, including additional toxicity testing, and an evaluation of facility operations and
maintenance practices, and best management practices. A Toxicity Identification Evaluation (TIE) may
be required as part of the TRE, if appropriate. A TIE is a set of procedures to identify the specific
chemicals responsible for toxicity. These procedures are performed in three phases (characterization,
identification, and confirmation) using aquatic organism toxicity tests.

13267, 13383.)
G. Bypass
1. Definitions
a. “Bypass” means the intentional diversion of waste streams from any portion of a
treatment facility. (40 C.F.R. § 122.41(m)(1)(i).)
b. “Severe property damage” means substantial physical damage to property, damage to the
treatment facilities, which causes them to become inoperable, or substantial and
permanent loss of natural resources that can reasonably be expected to occur in the
absence of a bypass. Severe property damage does not mean economic loss caused by
delays in production. (40 C.F.R. § 122.41(m)(1)(ii).)
2. Bypass not exceeding limitations. The Discharger may allow any bypass to occur which
does not cause exceedances of effluent limitations, but only if it is for essential maintenance
to assure efficient operation. These bypasses are not subject to the provisions listed in
Standard Provisions – Permit Compliance I.G.3, I.G.4, and I.G.5 below. (40 C.F.R.
§ 122.41(m)(2).)
3. Prohibition of bypass. Bypass is prohibited, and the Regional Water Board may take
enforcement action against a Discharger for bypass, unless (40 C.F.R. § 122.41(m)(4)(i)):
a. Bypass was unavoidable to prevent loss of life, personal injury, or severe property
damage (40 C.F.R. § 122.41(m)(4)(i)(A));
b. There were no feasible alternatives to the bypass, such as the use of auxiliary treatment
facilities, retention of untreated wastes, or maintenance during normal periods of
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment D – Standard Provisions D-3
equipment downtime. This condition is not satisfied if adequate back-up equipment
should have been installed in the exercise of reasonable engineering judgment to prevent
a bypass that occurred during normal periods of equipment downtime or preventive
maintenance (40 C.F.R. § 122.41(m)(4)(i)(B)); and
c. The Discharger submitted notice to the Regional Water Board as required under Standard
Provisions – Permit Compliance I.G.5 below. (40 C.F.R. § 122.41(m)(4)(i)(C).)
4. Approval. The Regional Water Board may approve an anticipated bypass, after considering
its adverse effects, if the Regional Water Board determines that it will meet the three
conditions listed in Standard Provisions—Permit Compliance I.G.3 above. (40 C.F.R.
§ 122.41(m)(4)(ii).)
5. Notice
a. Anticipated bypass. If the Discharger knows in advance of the need for a bypass, it shall
submit prior notice, if possible at least 10 days before the date of the bypass. The notice
shall be sent to the Regional Water Board. As of December 21, 2020, a notice shall also
be submitted electronically to the initial recipient defined in Standard Provisions –
Reporting V.J below. Notices shall comply with 40 C.F.R. part 3, 40 C.F.R. section
122.22, and 40 C.F.R. part 127. (40 C.F.R. § 122.41(m)(3)(i).)
b. Unanticipated bypass. The Discharger shall submit a notice of an unanticipated bypass
as required in Standard Provisions – Reporting V.E below (24-hour notice). The notice
shall be sent to the Regional Water Board. As of December 21, 2020, a notice shall also
be submitted electronically to the initial recipient defined in Standard Provisions –
Reporting V.J below. Notices shall comply with 40 C.F.R. part 3, 40 C.F.R. section
122.22, and 40 C.F.R. part 127. (40 C.F.R. § 122.41(m)(3)(ii).)
H. Upset
Upset means an exceptional incident in which there is unintentional and temporary noncompliance
with technology based permit effluent limitations because of factors beyond the reasonable control
of the Discharger. An upset does not include noncompliance to the extent caused by operational
error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive
maintenance, or careless or improper operation. (40 C.F.R. § 122.41(n)(1).)
1. Effect of an upset. An upset constitutes an affirmative defense to an action brought for
noncompliance with such technology based permit effluent limitations if the requirements of
Standard Provisions – Permit Compliance I.H.2 below are met. No determination made
during administrative review of claims that noncompliance was caused by upset, and before
an action for noncompliance, is final administrative action subject to judicial review.
(40 C.F.R. § 122.41(n)(2).)
2. Conditions necessary for a demonstration of upset. A discharger who wishes to establish
the affirmative defense of upset shall demonstrate, through properly signed,
contemporaneous operating logs or other relevant evidence that (40 C.F.R. § 122.41(n)(3)):
a. An upset occurred and that the Discharger can identify the cause(s) of the upset
(40 C.F.R. § 122.41(n)(3)(i));
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210

b. The permitted facility was, at the time, being properly operated (40 C.F.R.
§ 122.41(n)(3)(ii));
c. The Discharger submitted notice of the upset as required in Standard Provisions—
Reporting V.E.2.b below (24-hour notice) (40 C.F.R. § 122.41(n)(3)(iii)); and
d. The Discharger complied with any remedial measures required under Standard
Provisions—Permit Compliance I.C above. (40 C.F.R. § 122.41(n)(3)(iv).)
3. Burden of proof. In any enforcement proceeding, the Discharger seeking to establish the
occurrence of an upset has the burden of proof. (40 C.F.R. § 122.41(n)(4).)
II. STANDARD PROVISIONS—PERMIT ACTION
A. General
This Order may be modified, revoked and reissued, or terminated for cause. The filing of a request
by the Discharger for modification, revocation and reissuance, or termination, or a notification of
planned changes or anticipated noncompliance does not stay any Order condition. (40 C.F.R.
§ 122.41(f).)
B. Duty to Reapply
If the Discharger wishes to continue an activity regulated by this Order after the expiration date of
this Order, the Discharger must apply for and obtain a new permit. (40 C.F.R. § 122.41(b).)
C. Transfers
This Order is not transferable to any person except after notice to the Regional Water Board. The
Regional Water Board may require modification or revocation and reissuance of this Order to
change the name of the Discharger and incorporate such other requirements as may be necessary
under the CWA and the Water Code. (40 C.F.R. §§ 122.41(l)(3), 122.61.)
III.STANDARD PROVISIONS—MONITORING
A. Samples and measurements taken for the purpose of monitoring shall be representative of the
monitored activity. (40 C.F.R. § 122.41(j)(1).)
B. Monitoring must be conducted according to test procedures approved under 40 C.F.R. part 136
for the analyses of pollutants unless another method is required under 40 C.F.R. chapter 1,
subchapter N. Monitoring must be conducted according to sufficiently sensitive test methods
approved under 40 C.F.R. part 136 for the analysis of pollutants or pollutant parameters or
required under 40 C.F.R. chapter 1, subchapter N. For the purposes of this paragraph, a method
is sufficiently sensitive when:
1. The method minimum level (ML) is at or below the level of the effluent limitation
established in the permit for the measured pollutant or pollutant parameter, and either (a) the
method ML is at or below the level of the applicable water quality criterion for the measured
pollutant or pollutant parameter, or (b) the method ML is above the applicable water quality
criterion but the amount of the pollutant or pollutant parameter in a facility’s discharge is
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment D – Standard Provisions D-5
high enough that the method detects and quantifies the level of the pollutant or pollutant
parameter in the discharge; or
2. The method has the lowest ML of the analytical methods approved under 40 C.F.R. part 136
or required under 40 C.F.R. chapter 1, subchapter N, for the measured pollutant or pollutant
parameter.
In the case of pollutants or pollutant parameters for which there are no approved methods under
40 C.F.R. part 136 or otherwise required under 40 C.F.R. chapter 1, subchapter N, monitoring
must be conducted according to a test procedure specified in this Order for such pollutants or
pollutant parameters. (40 C.F.R. §§ 122.21(e)(3), 122.41(j)(4), 122.44(i)(1)(iv).)
IV. STANDARD PROVISIONS—RECORDS

V. TOXICITY TESTING REQUIREMENTS
The Discharger shall monitor acute and chronic toxicity at Monitoring Locations EFF-001 and
EFF-007, and chronic toxicity at Monitoring Locations RSW-001, RSW-004, and RSW-005.
A. Monitoring Locations EFF-001 and EFF-007
1. Acute Toxicity
a. Compliance with the acute toxicity effluent limitations shall be evaluated by measuring
survival of test organisms exposed to 96-hour static renewal bioassays.
b. Test organisms shall be rainbow trout (Oncorhynchus mykiss). The Executive Officer
may specify a more sensitive organism or, if testing a particular organism proves
unworkable, the most sensitive organism available.
c. All bioassays shall be performed according to the most up-to-date protocols in 40 C.F.R.
part 136, currently Methods for Measuring the Acute Toxicity of Effluents and Receiving
Water to Freshwater and Marine Organisms, 5th Edition (EPA-821-R-02-012).
d. If the Discharger demonstrates that specific identifiable substances in the discharge are
rapidly rendered harmless upon discharge to the receiving water, compliance with the
acute toxicity limit may be determined after test samples are adjusted to remove the
influence of those substances. Written acknowledgement that the Executive Officer
concurs with the Discharger’s demonstration and that the adjustment will not remove the
influence of other substances must be obtained prior to any such adjustment. The
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment E – MRP E-11
Discharger may manually adjust the pH of whole effluent acute toxicity samples prior to
performing bioassays to minimize ammonia toxicity interference.
e. Bioassay water monitoring shall include, on a daily basis, residual chlorine, pH, dissolved
oxygen, ammonia (if toxicity is observed), temperature, hardness, and alkalinity. These
results shall be reported. If a violation of an acute toxicity limit occurs, the bioassay test
shall be repeated with new fish as soon as practical and shall be repeated until a test fish
survival rate of 90 percent or greater is observed. If the control fish survival rate is less
than 90 percent, the bioassay test shall be restarted with new fish and shall continue as
soon as practical until an acceptable test is completed (i.e., control fish survival rate is
90 percent or greater).
2. Chronic Toxicity
a. Monitoring Requirements
i. Sampling. The Discharger shall collect 24-hour composite effluent samples at
Monitoring Locations EFF-001 and EFF-007 on consecutive or alternating days for
critical life stage toxicity testing as indicated below.
ii. Test Species. The test species shall be water flea (Ceriodaphnia dubia) unless a more
sensitive species is identified. If using this species proves unworkable, the Executive
Officer may specify a different species in writing upon the Discharger’s request with
justification.
The Discharger shall conduct a screening chronic toxicity test as described in
Appendix E-1, or as described in applicable State Water Board plan provisions that
become effective after adoption of this Order, following any significant change in the
nature of the effluent after implementation of the final treatment system. If there is no
significant change in the nature of the effluent, the Discharger shall conduct a
screening test for each discharge point and submit the results with its application for
permit reissuance. Upon completion of the chronic toxicity screening, the Discharger
shall use the most sensitive species to conduct subsequent monitoring.
iii. Frequency. Chronic toxicity monitoring shall be as specified below:
(a) The Discharger shall monitor routinely as indicated in Table E-2.
(b) The Discharger shall accelerate monitoring to monthly after exceeding either a
single-sample maximum of 2.0 TUc or a three-sample median of 1.0 TUc. The
Executive Officer may specify a different frequency to ensure that accelerated
monitoring provides useful information.
(c) The Discharger shall return to quarterly monitoring if accelerated monitoring does
not exceed either trigger in (b), above.
(d) If accelerated monitoring confirms consistent toxicity in excess of either trigger
in (b), above, the Discharger shall continue accelerated monitoring and initiate
toxicity reduction evaluation (TRE) procedures in accordance with section
V.A.2.c, below.
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment E – MRP E-12
(e) The Discharger shall return to routine monitoring after implementing appropriate
elements of the TRE, and either the toxicity drops below the triggers in (b),
above, or, based on the TRE results, the Executive Officer determines that
accelerated monitoring would no longer provide useful information.
(f) Monitoring conducted pursuant to a TRE satisfies the requirements for routine
and accelerated monitoring while the TRE is underway.
iv. Methodology. Sample collection, handling, and preservation shall be in accordance
with U.S. EPA protocols. In addition, bioassays shall be conducted in compliance
with Short-term Methods for Estimating the Chronic Toxicity of Effluents and
Receiving Waters to Freshwater Organisms, currently fourth Edition (EPA-821-R-
02-013). If these protocols prove unworkable, the Executive Officer and the
Environmental Laboratory Accreditation Program may grant exceptions in writing
upon the Discharger’s request with justification, provided that the revised protocols
are equally protective. If the Discharger demonstrates that specific identifiable
substances in the discharge are rapidly rendered harmless upon discharge to the
receiving water, compliance with the chronic toxicity limit may be determined after
test samples are adjusted to remove the influence of those substances. Written
acknowledgement that the Executive Officer concurs with the Discharger’s
demonstration and that the adjustment will not remove the influence of other
substances must be obtained prior to any such adjustment.
v. Dilution Series. The Discharger shall conduct tests at 100%, 75%, 50%, 25%, 12.5%,
and 0%. The “%” represents percent effluent as discharged. Test sample pH may be
controlled to the level of the effluent sample as received by the laboratory.
b. Reporting Requirements
i. The Discharger shall provide toxicity test results for the current reporting period in
the self-monitoring report and shall include the following, at a minimum, for each
test:
(a) Sample date
(b) Test initiation date
(c) Test species
(d) End point values for each dilution (e.g., number of young, growth rate, percent
survival)
(e) No Observable Effect Level (NOEL) values in percent effluent. The NOEL shall
equal the IC25 or EC25 (see MRP Appendix E-1). If the IC25 or EC25 cannot be
statistically determined, the NOEL shall equal to the No Observable Effect
Concentration (NOEC) derived using hypothesis testing. The NOEC is the
maximum percent effluent concentration that causes no observable effect on test
organisms based on a critical life stage toxicity test.
(f) IC15, IC25, IC40, and IC50 values (or EC15, EC25, EC40, and EC50) as percent
effluent
(g) TUc values (100/NOEL) and upper and lower confidence intervals.
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment E – MRP E-13
(h) Mean percent mortality (±s.d.) after 96 hours in 100% effluent (if applicable)
(i) IC50 or EC50 values for reference toxicant tests
(j) Available water quality measurements for each test (e.g., pH, residual chlorine,
dissolved oxygen, temperature, conductivity, hardness, salinity, and ammonia)
c. Toxicity Reduction Evaluation (TRE)
i. The Discharger shall prepare a generic TRE work plan within 90 days of the effective
date of this Order to be ready to respond to toxicity events. The Discharger shall
review and update the work plan as necessary so that it remains current and
applicable to the discharge and discharge facilities.
ii. Within 30 days of exceeding either chronic toxicity trigger in section V.A.2.a.iii.(b),
above, the Discharger shall submit a TRE work plan, which shall be the generic work
plan revised as appropriate for this toxicity event after consideration of available
discharge data.
iii. Within 30 days of completing an accelerated monitoring test observed to exceed
either chronic toxicity trigger in section V.A.2.a.iii.(b), above, the Discharger shall
initiate a TRE in accordance with a TRE work plan that incorporates any and all
comments from the Executive Officer.
iv. The TRE shall be specific to the discharge and be in accordance with current
technical guidance and reference materials, including U.S. EPA guidance materials.
The Discharger shall conduct the TRE as a tiered evaluation as summarized below:
(a) Tier 1 shall consist of basic data collection (routine and accelerated monitoring).
(b) Tier 2 shall consist of evaluation of treatment process optimization, including
operational practices and in-plant process chemicals.
(c) Tier 3 shall consist of a toxicity identification evaluation (TIE).
(d) Tier 4 shall consist of evaluation of options for additional effluent treatment
processes.
(e) Tier 5 shall consist of evaluation of options for modifications of in-plant treatment
processes.
(f) Tier 6 shall consist of implementation of selected toxicity control measures, and
follow-up monitoring and confirmation of implementation success.
v. The Discharger may end the TRE at any stage if monitoring finds there is no longer
consistent toxicity (i.e., chronic toxicity drops below both triggers in section
V.A.2.a.iii.(b), above).
vi. The objective of the TIE shall be to identify the substance or combination of
substances causing the observed toxicity. The Discharger shall employ all reasonable
efforts using currently available TIE methodologies.
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment E – MRP E-14
vii. As toxic substances are identified or characterized, the Discharger shall continue the
TRE by determining the sources and evaluating alternative strategies for reducing or
eliminating the toxic substances from the discharge. The Discharger shall take all
reasonable steps to reduce toxicity to levels below the triggers in section
V.A.2.a.iii.(b), above.
viii. Many recommended TRE elements parallel required or recommended efforts related
to source control, pollution prevention, and stormwater control programs. TRE efforts
should be coordinated with such efforts. To prevent duplication of efforts, evidence of
complying with requirements or recommended efforts of such programs may be
acceptable to demonstrate compliance with TRE requirements.
B. Monitoring Locations RSW-001, RSW-004, and RSW-005
1. Monitoring Requirements
a. Sampling. The Discharger shall collect samples for chronic toxicity testing as indicated
in Tables E-4 and E-6.
b. Test Species. The test species at Monitoring Locations RSW-001, RSW-004, and
RSW-005 shall be water flea (Ceriodaphnia dubia) and algae (Selenastrum
capricornutum).
c. Methodology. The Discharger shall use single-concentration toxicity tests (i.e., 100%
ambient water collected on the sampling day as a single grab). Once a toxicity test has
concluded, the Discharger shall evaluate organism performance (control vs. ambient
sample) using Surface Water Ambient Monitoring Program’s (SWAMP’s) standard
statistical protocol, which involves the examination of significant differences in test
organism performance by a one-tailed t-test (α = 0.05) or Test for Significant Toxicity
(TST), and a categorization of the performance of organisms exposed to the ambient
sample as either greater or less than 80 percent of the control performance (SWAMP
Toxicity Work Group Recommendation for Evaluating Toxicity Data, SWAMP, 2014;
Introduction to Toxicity Test Methodology and Applications, SWAMP, 2016; Final
Quality Assurance Program Plan, SWAMP, 2017). For purposes of receiving water
testing, a sample is considered toxic only when there is a significant t-test or TST result
and performance below the 80 percent threshold of the control is observed.
2. Reporting Requirements
a. The Discharger shall provide toxicity test results for the current reporting period in the
self-monitoring report and shall include the following, at a minimum, for each test:
i. Sample date
ii. Test initiation date
iii. Test species
iv. End point values for each dilution (e.g., number of young, growth rate, percent
survival)
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment E – MRP E-15
v. No Observable Effect Concentration (NOEC) values, derived using hypothesis
testing, in percent effluent. The NOEC is the maximum percent effluent concentration
that causes no observable effect on test organisms based on a critical life stage
toxicity test.
vi. TUc values (100/NOEC)
vii. Mean percent mortality (±s.d.) after 96 hours in 100% effluent (if applicable)
viii. IC50 or EC50 values for reference toxicant tests
ix. Available water quality measurements for each test (e.g., pH, residual chlorine,
dissolved oxygen, temperature, conductivity, hardness, salinity, and ammonia)
3. Toxicity Reduction Evaluation (TRE)
a. Monitoring Locations RSW-001 and RSW-004. The Discharger shall conduct a TIE
when it observes toxicity at Monitoring Location RSW-001 or RSW-004 and the
following circumstances exist:
i. the Discharger is not currently conducting a TRE for discharges from Discharge Point
Nos. 001 or 007,
ii. discharges from Discharge Point Nos. 001 or 007 are not otherwise identifiable as
causes of the observed toxicity (e.g., are not toxic concurrently with the receiving
water), and
iii. the percent effect in the receiving water sample is at least 50 percent and statistically
significant.
The Discharger shall conduct the TIE using the same sample and affected species. The
Discharger shall also follow MRP section V.A.2.c to investigate toxicity at Discharge
Point Nos. 001 and 007.
The Discharger shall select TIE treatments based on weight of evidence (e.g., nature of
the toxicity observed, historical TIE results, and concurrent analytical test results for
metals, minerals, suspended solids; etc.). The Discharger shall describe its rationale for
TIE treatment selection in the appropriate SMR.
The Discharger may conduct the TIE using a single species if more than one species
exhibits toxicity and the same cause is suspected. The Discharger may also conduct the
TIE on a sample from one monitoring location if toxicity is observed at both monitoring
locations and there is continuous flow between them. The Discharger shall describe its
rationale for species and monitoring location selection in the appropriate SMR.
The Discharger is not required to conduct a TIE if the cause of toxicity can be identified
based on weight-of-evidence using previous TRE or TIE data (e.g., there is a consistent
chemical signal associated with the observed toxicity). The Discharger shall report its
rationale for not conducting a TIE and identifying the cause of toxicity in the appropriate
SMR.
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment E – MRP E-16
If the percent effect in the receiving water sample is less than 50 percent but statistically
significant, the Discharger shall analyze possible causes of toxicity based on available
data (e.g., trace metals, mineral content, turbidity, or test-related quality assurance or
quality control data) and report the results in the appropriate SMR.
b. Monitoring Location RSW-005. If the Discharger observes toxicity at Monitoring
Location RSW-005 and is not currently conducting a TRE for discharges from Discharge
Point Nos. 001 or 007, the Discharger shall assess whether the toxicity could be due to
stormwater discharged from Discharge Point Nos. 002, 004, 005, or 006. The Discharger
may also evaluate other possible sources, such as contaminated runoff entering the creek
downstream of the Facility, that may be causing the toxicity.
VI. REPORTING REQUIREMENTS
A. General Monitoring and Reporting Requirements
The Discharger shall comply with all standard provisions (Attachments D, G, and S) related to
monitoring, reporting, and recordkeeping.
B. Self-Monitoring Reports (SMRs)
1. SMR Format. The Discharger shall electronically submit SMRs using the State Water
Board’s California Integrated Water Quality System (CIWQS) Website

4. RL and MDL Reporting. The Discharger shall report with each sample result the Reporting
Level (RL) and Method Detection Limit (MDL) as determined by the procedure in 40 C.F.R.
part 136. The Discharger shall report the results of analytical determinations for the presence
of chemical constituents in a sample using the following reporting protocols:
a. Sample results greater than or equal to the RL shall be reported as measured by the
laboratory (i.e., the measured chemical concentration in the sample).
b. Sample results less than the RL, but greater than or equal to the laboratory’s MDL, shall
be reported as “Detected, but Not Quantified,” or DNQ. The estimated chemical
concentration of the sample shall also be reported.
For purposes of data collection, the laboratory shall write the estimated chemical
concentration next to DNQ. The laboratory may, if such information is available, include
numerical estimates of the data quality for the reported result. Numerical estimates of
data quality may be percent accuracy (+/- a percentage of the reported value), numerical
ranges (low to high), or any other means the laboratory considers appropriate.
c. Sample results less than the laboratory’s MDL shall be reported as “Not Detected” or
ND.
d. The Discharger shall instruct laboratories to establish calibration standards so that the
minimum level (ML) value (or its equivalent if there is differential treatment of samples
relative to calibration standards) is the lowest calibration standard. At no time is the
Discharger to use analytical data derived from extrapolation beyond the lowest point of
the calibration curve.
5. Compliance Determination. Compliance with effluent limitations for priority pollutants
shall be determined using sample reporting protocols defined above and in the Fact Sheet and
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment E – MRP E-19
Attachments A, D, and G. For purposes of reporting and administrative enforcement by the
Regional Water Board and State Water Board, the Discharger shall be deemed out of
compliance with effluent limitations if the concentration of the priority pollutant in the
monitoring sample is greater than the effluent limitation and greater than or equal to the
reporting level (RL).

CHRONIC TOXICITY
DEFINITION OF TERMS AND SCREENING PHASE REQUIREMENTS
I. Definition of Terms
A. No observed effect level (NOEL) for compliance determination is equal to IC25 or EC25. If
the IC25 or EC25 cannot be statistically determined, the NOEL shall be equal to the NOEC
derived using hypothesis testing.
B. Effective concentration (EC) is a point estimate of the toxicant concentration that would
cause an adverse effect on a quantal, “all or nothing,” response (such as death,
immobilization, or serious incapacitation) in a given percent of the test organisms. If the
effect is death or immobility, the term lethal concentration (LC) may be used. EC values may
be calculated using point estimation techniques such as probit, logit, and Spearman-Karber.
EC25 is the concentration of toxicant (in percent effluent) that causes a response in 25 percent
of the test organisms.
C. Inhibition concentration (IC) is a point estimate of the toxicant concentration that would
cause a given percent reduction in a nonlethal, nonquantal biological measurement, such as
growth. For example, an IC25 is the estimated concentration of toxicant that would cause a 25
percent reduction in average young per female or growth. IC values may be calculated using
a linear interpolation method such as U.S. EPA’s Bootstrap Procedure.
D. No observed effect concentration (NOEC) is the highest tested concentration of an effluent or
a toxicant at which no adverse effects are observed on the aquatic test organisms at a specific
time of observation. It is determined using hypothesis testing.
II. Chronic Toxicity Screening Phase Requirements
A. The Discharger shall perform screening phase monitoring:
1. Subsequent to any significant change in the nature of the effluent discharged through
changes in sources or treatment, except those changes resulting from reductions in
pollutant concentrations attributable to source control efforts, or
2. Prior to permit reissuance. Screening phase monitoring data shall be included in the
NPDES permit application for reissuance. The information shall be as recent as possible,
but may be based on screening phase monitoring conducted within 5 years before the
permit expiration date.
B. Design of the screening phase shall, at a minimum, consist of the following elements:
1. Use of test species specified in Appendix E-2, attached, and use of the protocols
referenced in those tables.
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment E – MRP E-21
2. Two stages:
a. Stage 1 shall consist of a minimum of one battery of tests conducted concurrently.
Selection of the type of test species and minimum number of tests shall be based on
Appendix E-2 (attached).
b. Stage 2 shall consist of a minimum of two test batteries conducted at a monthly
frequency using the three most sensitive species based on the Stage 1 test results.
3. Appropriate controls.
4. Concurrent reference toxicant tests.
5. Dilution series of 100%, 50%, 25%, 12.5%, 6.25%, and 0 %, where “%” is percent
effluent as discharged, or as otherwise approved the Executive Officer if different
dilution ratios are needed to reflect discharge conditions.
C. The Discharger shall submit a screening phase proposal. The proposal shall address each of
the elements listed above. If within 30 days, the Executive Officer does not comment, the
Discharger shall commence with screening phase monitoring.

A. Lehigh Southwest Cement Company operates the Permanente Plant (Facility), a limestone quarry
and cement production facility that also produces construction aggregate. Hanson Permanente
Cement, Inc., owns the property on which the Facility is located at 24001 Stevens Creek Road.
Together, Lehigh Southwest Cement Company and Hanson Permanente Cement, Inc., are
hereinafter referred to as the “Discharger.” Site operations commenced in 1939.
For the purposes of this Order, references to the “discharger” or “permittee” in applicable federal
and State laws, regulations, plans, or policies are held to be equivalent to references to the
Discharger herein.
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment F – Fact Sheet F-3
B. The Facility discharges wastewater to Permanente Creek, a water of the United States tributary
to San Francisco Bay within the Santa Clara Basin watershed. The Facility also discharges
stormwater runoff associated with industrial activities to Permanente Creek. Attachment B
provides a map of the Facility and area around the Facility. Attachment C provides a site flow
and treatment process schematic for the Facility.
The Discharger is regulated pursuant to National Pollutant Discharge Elimination System
(NPDES) Permit No. CA0030210. The Discharger was previously subject to Order No.
R2-2014-0010, which the Regional Water Board amended through Order No. R2-2017-0030
(together, the previous order). The Discharger filed a Report of Waste Discharge and submitted
an application for reissuance of its Waste Discharge Requirements (WDRs) and NPDES permit
on August 1, 2018.
The Discharger is authorized to discharge subject to the WDRs in this Order at the discharge
locations described in Table 2 of this Order. Regulations at 40 C.F.R. section 122.46 limit the
duration of NPDES permits to a fixed term not to exceed five years. Accordingly, Table 3 of this
Order limits the effective period for the discharge authorization. Pursuant to California Code of
Regulations, title 23, section 2235.4, the terms and conditions of an expired permit are
automatically continued pending reissuance of the permit if the Discharger complies with all
federal NPDES regulation requirements for continuation of expired permits.
C. The Discharger is also subject to Regional Water Board Order No. 94-038 for treatment and onsite
discharge and reuse (or reclamation) of treated sanitary wastewaters. This Order does not affect
Order No. 94-038.
D. When applicable, State law requires dischargers to file a petition with the State Water Resources
Control Board (State Water Board), Division of Water Rights, and receive approval for any change
in the point of discharge, place of use, or purpose of use of treated wastewater that decreases the
flow in any portion of a watercourse. The State Water Board retains separate jurisdictional authority
to enforce such requirements under Water Code section 1211. This is not an NPDES permit
requirement.
II. FACILITY DESCRIPTION
The Discharger mines and processes minerals at the Facility and produces Portland cement and
construction aggregate from limestone and other stone quarried onsite. It produces several types of
wastewater, including quarry dewatering water, truck and equipment wash water, aggregate crushing
and washing water, cement manufacture process wastewater, and industrial stormwater. This Order
addresses all wastewater (including industrial stormwater) associated with quarrying, crushed rock
mining and processing, and cement manufacture at the Facility.
The Facility consists of an active mining area, a quarry pit, a cement manufacturing plant, several
crushers and mills, a pre-calcining tower, and roads and a conveyor system for transporting mined
raw materials. Wastewater and industrial stormwater are collected and managed through a system of
berms, ditches, pipes, and ponds. The ponds discharge to Permanente Creek at several locations.
Runoff also occurs as sheet flow from undisturbed areas.

Attachment F – Fact Sheet F-4
A. Discharge Points and Receiving Waters
The Facility discharges to Permanente Creek, a freshwater stream tributary to San Francisco
Bay. All the Facility’s discharges are shallow water discharges. The discharge points are located
in the Santa Clara Basin watershed, as indicated below:
Table F-2. Outfall Locations
Discharge Point Latitude (North) Longitude (West) Receiving Water
001 37.31713° -122.11165° Permanente Creek
002 37.31674° -122.10167° Permanente Creek
004 37.31431° -122.08893° Permanente Creek
005 37.31899° -122.08716° Permanente Creek
006 37.32241° -122.08551° Permanente Creek
007 37.31778° -122.08750° Permanente Creek
B. Existing Wastewater Treatment and Controls
The Facility’s industrial wastewater treatment system, called the Final Treatment System (FTS),
consists of two treatment trains, the Upper Treatment System (FTS-Upper), located near Pond 4A at
the quarry pit crest, and the Lower Treatment System (FTS-Lower), located near Pond 11 and the
Cement Plant (see Attachment B, Water System and Piping figure). Each treatment train includes
ultrafiltration/reverse osmosis (UF/RO) units to remove dissolved solids and bioreactors to remove
selenium and other metals. The bioreactors are a proprietary anaerobic attached growth system with
a final filtration step. The FTS-Upper treatment capacity is 66,000 gallons per hour (gph); the
FTS-Lower treatment capacity is 72,000 gph. The FTS-Upper discharges at Discharge Point
No. 001; the FTS-Lower discharges at Discharge Point No. 007.
During normal operations, the Discharger pumps quarry dewatering water and stormwater collected
in the quarry pit either to Pond 1250, then to the FTS-Upper; or to Tank 950, then to the FTS-Lower
(see Attachment C). The Discharger may also use water from Pond 1250 for dust suppression on
quarry roads. The Discharger directs process wastewater from the Cement Plant, Rock Plant, and
Truck Wash, and stormwater from the Dinky Shed basin and Cement Plant area, to Pond 1, then to
Pond 11. (The Dinky Shed basin collects stormwater from the Rock Plant access road and
surrounding areas, along with stormwater from nearby roads.) The Discharger sends industrial
stormwater from the Pond 30 area and Eastern Materials Storage Area (EMSA), subsurface flow
intercepted by the EMSA French drain, bioreactor and UF/RO backwash water, and UF/RO
concentrate directly to Pond 11. The Discharger either reclaims water collected in Pond 11 for use
as process water or sends it to the quarry pit for treatment at either the FTS-Upper or FTS-Lower.
During the rainy season, the Discharger may use the quarry pit as equalization storage to store water
for later treatment and discharge.
The Discharger discharges stormwater that does not require treatment at the FTS to Permanente
Creek at four other locations: Discharge Point Nos. 002 (from Pond 13B), 004 (from Pond 17), 005
(from Pond 20), and, as necessary, 006 (from Pond 30). Stormwater flows to these discharge points
from the areas listed in Table 1 and are treated using stormwater Best Management Practices
(BMPs). The Discharger has eliminated all process and industrial stormwater discharges to Pond 9;
therefore, this Order no longer authorizes discharges from former Discharge Point No. 003
(Pond 9).

C. Summary of Existing Requirements and Monitoring Data
The table below presents the previous order’s effluent limitations and representative monitoring
data from the previous order term. There were no discharges from Discharge Point Nos. 002 or
007, so those discharge points are omitted from the table. The table includes metals data for
Discharge Point Nos. 003 through 006, although those discharge points did not have effluent
limits for metals.

D. Compliance Summary
The Discharger’s compliance record is summarized below:
1. Cease and Desist Order. Cease and Desist Order R2-2014-0002, as amended through Order
No. R2-2017-0031, required tasks and a schedule for the Discharger to comply with the
previous order by October 1, 2017. The tasks were corrective actions for foreseeable future
violations and included the following:
• Pilot-testing an Interim Treatment System (ITS) to treat Facility process wastewater,
quarry water, and industrial wastewater discharges as necessary to meet the previous
order’s effluent limits, particularly for selenium, at Discharge Point No. 001.
• Operating the ITS for up to 400 gallons per minute.
• Constructing a Final Treatment System (FTS), based on the ITS, to treat all Facility
discharges as necessary to comply with the previous order’s effluent limits.
• Reconfiguring Facility flows to send all water needing treatment to the FTS and
Discharge Point No. 001, and to discharge only stormwater not needing further treatment
at Discharge Point Nos. 002 through 006.
• Installing and operating the FTS.
The Cease and Desist Order also imposed interim limits while the Discharger completed
these tasks.
2. Administrative Civil Liabilities

[1] This violation was detected in the effluent from the Upper FTS.
[2] This violation was detected in the effluent from the Lower FTS.
On May 21, 2019, the Regional Water Board issued Order No. R2-2019-1014, fining the
Discharger $6,000 for the November and December 2017, and March 2018 violations above.
Enforcement for the April 2019 violations is pending.
The Discharger also discharged 2,250 gallons of untreated truck wash water from Discharge
Point No. 005 on May 8, 2018. This unauthorized discharge was caused by leaking fittings
on a pipeline that was to convey truck wash water to Pond 1 and then to the FTS. The fittings
had been loosened during pipeline maintenance and not re-tightened. The Discharger noticed
the leaking fittings about one hour after completing the maintenance, tightened the fittings,
and stopped the leak.
III.APPLICABLE PLANS, POLICIES, AND REGULATIONS
A. Legal Authorities. This Order serves as WDRs pursuant to Water Code article 4, chapter 4,
division 7 (commencing with § 13260). This Order is also issued pursuant to Clean Water Act
(CWA) section 402 and implementing regulations adopted by U.S. EPA, and Water Code
chapter 5.5, division 7 (commencing with § 13370). It shall serve as an NPDES permit
authorizing the Discharger to discharge into waters of the United States at the discharge locations
described in Table 2 subject to the WDRs in this Order.

B. California Environmental Quality Act. Under Water Code section 13389, this action to adopt
an NPDES permit is exempt from the provisions of the California Environmental Quality Act
(CEQA), Public Resources Code division 13, chapter 3 (commencing with § 21100).
C. State and Federal Regulations, Policies, and Plans
1. Water Quality Control Plan. The San Francisco Bay Regional Water Board (Regional
Water Board) adopted The Water Quality Control Plan for the San Francisco Bay Basin
(hereinafter Basin Plan) that designates beneficial uses, establishes water quality objectives,
and contains implementation programs and policies to achieve those objectives for all waters
addressed through the plan. Requirements in this Order implement the Basin Plan. In
addition, State Water Board Resolution 88-63 established State policy that all waters, with
certain exceptions, should be considered suitable or potentially suitable for municipal or
domestic supply. Permanente Creek does not meet any of the exceptions under State Water
Board Resolution 88-63. Therefore, the municipal or domestic supply beneficial use applies.
Beneficial uses applicable to Permanente Creek are as follows:

2. National Toxics Rule (NTR) and California Toxics Rule (CTR). U.S. EPA adopted the
NTR on December 22, 1992, and amended it on May 4, 1995, and November 9, 1999. About
40 criteria in the NTR apply in California. On May 18, 2000, U.S. EPA adopted the CTR.
The CTR promulgated new toxics criteria for California and incorporated the previously
adopted NTR criteria that applied in the State. U.S. EPA amended the CTR on February 13,
2001. These rules contain water quality criteria for priority pollutants.
3. State Implementation Policy. On March 2, 2000, the State Water Board adopted the Policy
for Implementation of Toxics Standards for Inland Surface Waters, Enclosed Bays, and
Estuaries of California (State Implementation Policy or SIP). The SIP became effective on
April 28, 2000, with respect to the priority pollutant criteria U.S. EPA promulgated for
California through the NTR and the priority pollutant objectives the Regional Water Board
established in the Basin Plan. The SIP became effective on May 18, 2000, with respect to the
priority pollutant criteria U.S. EPA promulgated through the CTR. The State Water Board
adopted amendments to the SIP on February 24, 2005, that became effective on July 13,
2005. The SIP establishes implementation provisions for priority pollutant criteria and
objectives, and provisions for chronic toxicity control. Requirements of this Order implement
the SIP.
4. Antidegradation Policy. Federal regulations at 40 C.F.R. section 131.12 requires that state
water quality standards include an antidegradation policy consistent with the federal policy.
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment F – Fact Sheet F-10
The State Water Board established California’s antidegradation policy through State Water
Board Resolution 68-16, which is deemed to incorporate the federal antidegradation policy
where the federal policy applies under federal law. Resolution 68-16 requires that existing
water quality be maintained unless degradation is justified based on specific findings. The
Basin Plan implements, and incorporates by reference, both the State and federal
antidegradation policies. Permitted discharges must be consistent with the antidegradation
provisions of 40 C.F.R. section 131.12 and State Water Board Resolution 68-16. (See Fact
Sheet § IV.D.1 Antidegradation.)
5. Domestic Water Quality. In accordance with Water Code section 106.3, it is the policy of
the State of California is that every human being has the right to safe, clean, affordable, and
accessible water adequate for human consumption, cooking, and sanitary purposes. This
Order complies with that policy by requiring discharges to meet maximum contaminant
levels (MCLs) designed to protect human health and ensure that water is safe for domestic
use.
6. Anti-Backsliding Requirements. CWA sections 402(o) and 303(d)(4) and 40 C.F.R. section
122.44(l) restrict backsliding in NPDES permits. These anti-backsliding provisions require
that effluent limitations in a reissued permit be as stringent as those in the previous permit,
with some exceptions in which limitations may be relaxed. (See Fact Sheet § IV.D.2 Anti-
Backsliding.)
7. Endangered Species Act Requirements. This Order does not authorize any act that results
in the taking of a threatened or endangered species or any act that is now prohibited, or
becomes prohibited in the future, under either the California Endangered Species Act (Fish
and Game Code §§ 2050 to 2097) or the Federal Endangered Species Act (16 U.S.C.A.
§§ 1531 to 1544). This Order requires compliance with effluent limits, receiving water limits,
and other requirements to protect beneficial uses, including protecting rare, threatened, or
endangered species. The Discharger is responsible for meeting all applicable Endangered
Species Act requirements.
8. Mercury Provisions. On May 2, 2017, the State Water Board adopted Resolution 2017-
0027, which approved Final Part 2 of the Water Quality Control Plan for Inland Surface
Waters, Enclosed Bays, and Estuaries of California—Tribal and Subsistence Fishing
Beneficial Uses and Mercury Provisions (Mercury Provisions), thereby establishing water
quality objectives for mercury in most State waters. The Mercury Provisions (section III.D.3)
supersede the freshwater mercury water quality objectives in Basin Plan Table 3-4.
Requirements of this Order implement the Mercury Provisions.
D. Impaired Waters on CWA 303(d) List. In April 2018, U.S. EPA approved a revised list of
impaired waters prepared pursuant to CWA section 303(d), which requires identification of
specific water bodies where it is expected that water quality standards will not be met after
implementation of technology-based effluent limitations on point sources. Where necessary, the
Regional Water Board plans to adopt Total Maximum Daily Loads (TMDLs) for waters on the
303(d) list to establish wasteload allocations for point sources and load allocations for nonpoint
sources and thus achieve the water quality standards. Permanente Creek is listed as impaired due
to selenium, diazinon, toxicity, and trash:
1. Selenium. Available information suggests that Facility discharges are the predominant
source of selenium in Permanente Creek. The Regional Water Board intends to resolve the
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment F – Fact Sheet F-11
selenium impairment by adopting this Order, which contains effluent limitations and requires
implementation of BMPs sufficient to achieve water quality standards in Permanente Creek.
This Order also contains monitoring and reporting requirements to allow the Regional Water
Board to evaluate progress toward achieving the water quality standards and eliminating the
impairment.
2. Diazinon and Toxicity. On May 16, 2007, U.S. EPA approved a TMDL for diazinon
(a pesticide) and pesticide-related toxicity in urban creeks as set forth in Basin Plan
section 7.1.1. The TMDL allocates the entire wasteload allocations for diazinon and
pesticide-related toxicity to municipal stormwater. Available data do not indicate that Facility
discharges contain diazinon or pesticide-related toxicity. As explained in Fact Sheet section
IV.C.3.f, Facility discharges do not pose a reasonable potential to cause or contribute to
exceedance of the Basin Plan’s toxicity objective. Nevertheless, this Order requires toxicity
monitoring to ensure that any potential sources of toxicity other than pesticides are identified
and resolved.
3. Trash. Facility discharges are not a source of trash to Permanente Creek. The Regional
Water Board addressed the trash impairment when it reissued the Municipal Separate Storm
Sewer System NPDES permit (NPDES Permit No. CAS612008).
IV. RATIONALE FOR EFFLUENT LIMITATIONS AND DISCHARGE SPECIFICATIONS
The Clean Water Act requires point source dischargers to control the amount of conventional, nonconventional,
and toxic pollutants discharged into waters of the United States. The control of
pollutants discharged is established through effluent limitations and other requirements in NPDES
permits. There are two principal bases for effluent limitations: 40 C.F.R. section 122.44(a) requires
that permits include applicable technology-based limitations and standards; and 40 C.F.R. section
122.44(d) requires that permits include water quality-based effluent limitations to attain and
maintain applicable numeric and narrative water quality criteria to protect the beneficial uses of
receiving waters.
A. Discharge Prohibitions
1. Prohibitions in this Order
a. Discharge Prohibition III.A (No discharge other than as described in this Order): This
prohibition is based on 40 C.F.R. section 122.21(a), duty to apply, and Water Code
section 13260, which requires filing an application and Report of Waste Discharge before
discharges can occur. Discharges not described in the permit application and Report of
Waste Discharge, and subsequently in this Order, are prohibited.
b. Discharge Prohibition III.B (No flow above 167,000 gph at Discharge Point Nos. 001
and 007 combined): This prohibition ensures that wastewater flows do not exceed the
design capacity of the wastewater treatment system.
c. Discharge Prohibition III.C (No discharge other than that due to precipitation at
Discharge Point Nos. 002 and 004 through 006): This prohibition ensures that these
discharge points only discharge stormwater.
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment F – Fact Sheet F-12
d. Discharge Prohibition III.D (No discharge of kiln exhaust cooling water): This
prohibition ensures that elevated temperature wastewater will not be discharged to
Permanente Creek. During normal plant operations all kiln exhaust cooling water is
evaporated. Because this Order includes this prohibition, an effluent temperature
limitation is unnecessary.
2. Exception to Shallow Water Discharge Prohibition. Basin Plan Table 4-1, Discharge
Prohibition 1, prohibits discharges not receiving a minimum of 10:1 initial dilution. Basin
Plan section 4.2 provides for exceptions under certain circumstances:
• An inordinate burden would be placed on the Discharger relative to the beneficial uses
protected, and an equivalent level of environmental protection can be achieved by
alternate means;
• A discharge is approved as part of a reclamation project;
• Net environmental benefits will be derived as a result of the discharge; or
• A discharge is approved as part of a groundwater cleanup project.
The Basin Plan further states:
Significant factors to be considered by the Regional Water Board in reviewing
requests for exceptions will be the reliability of the discharger’s system in
preventing inadequately treated wastewater from being discharged to the
receiving water and the environmental consequences of such discharges.
This Order grants an exception for discharges to Permanente Creek for the following reasons:
a. An inordinate burden would be placed on the Discharger relative to the beneficial uses
protected to require the discharge to achieve 10:1 dilution in Permanente Creek.
Upstream flow in Permanente Creek is insufficient to achieve 10:1 dilution consistently
throughout the year, and constructing and operating a deepwater outfall to provide
consistent dilution (e.g., in San Francisco Bay) would require construction and operation
of a discharge pipe several miles long.
b. For treated wastewater discharges from Discharge Point Nos. 001 and 007, the
Discharger will provide an equivalent level of environmental protection through
advanced treatment to minimize pollutants and comply with this Order’s stringent
effluent limitations. Furthermore, the Discharger will be able to contain untreated or
partially treated wastewater in the quarry pit in case of possible treatment upset, allowing
it to be re-routed for treatment prior to discharge.
c. For stormwater discharges from Discharge Point Nos. 002 and 004 through 006,
Provision VI.A.3 of this Order and Attachment S require the Discharger to provide an
equivalent level of environmental protection by developing and implementing BMPs
reflecting best industry practice considering technological availability and economic
practicability to comply with effluent limits and minimize pollutants in stormwater.

Attachment F – Fact Sheet F-13
B. Technology-Based Effluent Limitations
1. Scope and Authority
CWA section 301(b) and 40 C.F.R. section 122.44 require that permits include conditions
meeting technology-based requirements at a minimum and any more stringent effluent
limitations necessary to meet water quality standards. The discharges this Order authorizes
must meet minimum federal technology-based requirements based on U.S. EPA-promulgated
Effluent Limitations Guidelines for the Cement Manufacturing Point Source Category at
40 C.F.R. section 411 and the Mining Point Source Category at 40 C.F.R. section 436. The
effluent limitations established by these codes and their applicability to the discharges
permitted by this Order are summarized below and in Table F-5:
• Regulations at 40 C.F.R. section 411 subpart A (Nonleaching Subcategory) apply to
process wastewater from nonleaching cement manufacturing directed to Discharge Point
Nos. 001 and 007.
• Regulations at 40 C.F.R. section 411 subpart C (Materials Storage Piles Runoff
Subcategory) apply to Discharge Point Nos. 001, 002, and 004 through 007 because these
discharges contain runoff from raw materials, intermediate products, finished products, or
waste materials.
• Regulations at 40 C.F.R. section 436 subparts B (Crushed Stone Subcategory) and C
(Construction Sand and Gravel Subcategory) apply to Discharge Point Nos. 001 and 007
because these discharges contain mine dewatering water or wastewater associated with
mining and processing crushed stone, such as the limestone used in cement
manufacturing and the construction aggregate produced at the Facility.
The requirements of these Effluent Limit Guidelines are summarized below. The Basin Plan
contains additional requirements for certain pollutants.

[2] Untreated overflow from facilities designed, constructed, and operated to treat the volume of runoff from materials storage
associated with a 10-year 24-hour rain event is not subject to this limitation. Because none of the Facility’s ponds meet these
conditions, all discharges covered by this Order are subject to this limitation.

PERMANENTE PLANT NPDES No. CA0030210
Attachment F – Fact Sheet F-14
2. Effluent Limitations
Rationales for this Order’s technology-based effluent limitations are presented below:
a. Discharge Point Nos. 001 and 007
Discharges from Discharge Point Nos. 001 and 007 are subject to the Effluent Limitation
Guidelines as set forth in Table F-6.
i. Total Suspended Solids (TSS). The TSS effluent limitation applies to the combined
discharge from Discharge Point Nos. 001 and 007, monitored at Monitoring
Locations EFF-001 and EFF-007, and is based on the rate of cement production in
accordance with 40 C.F.R. section 411 subpart A (Non-leaching Subcategory). The
Discharger’s Report of Waste Discharge reports its production rate as 11,520,000
pounds (lbs) of Portland cement per day. The maximum daily TSS limit is therefore
calculated as follows:
11,520,000 lbs cement /day x 0.005 lbs TSS / 1,000 lbs cement = 58 lbs/day TSS
This Order does not contain the TSS effluent limitations in Basin Plan Table 4-2
because the Basin Plan states, “[the TSS limits] will not be used to preempt Effluent
Guideline Limitations.”
ii. Oil and Grease. The oil and grease effluent limitations are based on Basin Plan
Table 4-2.
iii. pH. The pH effluent limitations are based on Basin Plan Table 4-2, which is more
stringent than 40 C.F.R. sections 411 and 436.
iv. Total Residual Chlorine. The total residual chlorine effluent limitation is based on
Basin Plan Table 4-2. Chlorine may be present when potable water is used onsite as
make-up Primary Crusher wash water, Rock Plant wash water, Truck Wash water, or
dust suppression water.
v. Settleable Matter. The settleable matter effluent limitations are based on Basin Plan
Table 4-2.
b. Discharge Point Nos. 002, 004, 005, and 006
Discharges from Discharge Point Nos. 002, 004, 005, and 006 are subject to the Effluent
Limitation Guidelines in 40 C.F.R. section 411 subpart C (Materials Storage Piles Runoff
Subcategory).
i. Total Suspended Solids (TSS). The TSS effluent limitation is based on 40 C.F.R.
section 411, Subpart C (Materials Storage Piles Runoff Subcategory). This Order
does not contain the TSS effluent limitations in Basin Plan Table 4-2 because the
Basin Plan states, “[the TSS limits] will not be used to preempt Effluent Guideline
Limitations.”
ii. Oil and Grease. The oil and grease effluent limitations are based on Basin Plan
Table 4-2.
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment F – Fact Sheet F-15
iii. pH. The pH effluent limitations are based on Basin Plan Table 4-2, which is more
stringent than 40 C.F.R. sections 411 and 436.
iv. Settleable Matter. The settleable matter effluent limitations are based on Basin Plan
Table 4-2.
C. Water Quality-Based Effluent Limitations
1. Scope and Authority
This Order contains water quality-based effluent limitations (WQBELs) that protect
beneficial uses. CWA section 301(b) and 40 C.F.R. section 122.44(d) require that permits
include limitations more stringent than federal technology-based requirements where
necessary to achieve applicable water quality standards. According to 40 C.F.R. section
122.44(d)(1)(i), permits must include effluent limitations for all pollutants that are or may be
discharged at levels that have a reasonable potential to cause or contribute to an exceedance
of a water quality standard, including numeric and narrative objectives within a standard.
Where reasonable potential has been established for a pollutant, but there is no numeric
criterion or objective, WQBELs must be established using (1) U.S. EPA criteria guidance
under CWA section 304(a), supplemented where necessary by other relevant information;
(2) an indicator parameter for the pollutant of concern; or (3) a calculated numeric water
quality criterion, such as a proposed state criterion or policy interpreting a narrative criterion,
supplemented with relevant information (40 C.F.R. § 122.44[d][1][vi]). The process for
determining reasonable potential and calculating WQBELs is intended to achieve applicable
water quality objectives and criteria and protect designated uses of receiving waters as
specified in the Basin Plan. When numeric effluent limitations are infeasible, 40 C.F.R. part
122.44(k) allows WQBELs to be expressed narratively, such as through BMPs.
2. Beneficial Uses and Water Quality Criteria and Objectives
Discharge Point Nos. 001, 002, and 004 through 007 discharge to Permanente Creek. Fact
Sheet section III.C.1, above, identifies the beneficial uses of Permanente Creek. Water
quality criteria and objectives to protect these beneficial uses are described below:
a. Basin Plan Objectives. The Basin Plan specifies numerous water quality objectives,
such as numeric objectives for 10 priority pollutants and un-ionized ammonia, and
narrative objectives for toxicity and bioaccumulation. Because Permanente Creek has the
MUN beneficial use based on State Water Board Resolution No. 88-63 (see Fact Sheet
§ III.C.1), drinking water standards (i.e., maximum contaminant levels) also apply as
water quality objectives.
i. Ammonia. Basin Plan section 3.3.20 contains a water quality objective for un-ionized
ammonia of 0.025 mg/L as an annual median for San Francisco Bay region receiving
waters. Effluent and receiving water data are available for total ammonia, but not unionized
ammonia, because (1) sampling and laboratory methods are unavailable to
analyze for un-ionized ammonia, and (2) the fraction of total ammonia that exists in
the toxic un-ionized form depends on pH, salinity, and temperature of the receiving
water.
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment F – Fact Sheet F-16
To translate the un-ionized ammonia objectives into total ammonia criteria, pH,
salinity, and temperature data collected at Monitoring Location RSW-001A from
March 2016 through July 2018 were used. The un-ionized fraction of total ammonia
was calculated using the following equation, which applies to waters with salinities
less than 1 part per thousand (ppt) (Ambient Water Quality Criteria for Ammonia
(Saltwater)–1989, EPA Publication 440/5-88-004, 1989):
For salinity < 1 ppt: fraction of NH3 =
Where:
pK = 0.09018 + 2729.92/(T)
T = temperature in Kelvin
The median un-ionized ammonia fraction was then used to express the annual average
un-ionized objective as a chronic total ammonia criterion. This approach is consistent
with U.S. EPA guidance on translating dissolved metal water quality objectives to
total recoverable metal water quality criteria (U.S. EPA, 1996, The Metals
Translator: Guidance for Calculating a Total Recoverable Limit form a Dissolved
Criterion, EPA Publication 823-B96-007). The equivalent chronic total ammonia
criterion is 1.2 mg/L.
ii. Dioxin-TEQ. The narrative bioaccumulation objective (Basin Plan section 3.3.2)
states, “Many pollutants can accumulate on particulates, in sediments, or
bioaccumulate in fish and other aquatic organisms. Controllable water quality factors
shall not cause a detrimental increase in concentrations of toxic substances found in
bottom sediments or aquatic life. Effects on aquatic organisms, wildlife, and human
health will be considered.” Because it is the consensus of the scientific community
that dioxins and furans associate with particulates, accumulate in sediments, and
bioaccumulate in the fatty tissue of fish and other organisms, the Basin Plan’s
narrative bioaccumulation water quality objective applies to these pollutants. Elevated
levels of dioxins and furans in San Francisco Bay fish tissue demonstrate that the
narrative bioaccumulation water quality objective is not being met. U.S. EPA has
therefore placed Lower San Francisco Bay on its 303(d) list of receiving waters
where water quality objectives are not being met after imposition of applicable
technology-based requirements.
When the CTR was promulgated, U.S. EPA stated its support for the regulation of
dioxin and dioxin-like compounds through the use of toxicity equivalencies (TEQs).
U.S. EPA stated, “For California waters, if the discharge of dioxin or dioxin-like
compounds has reasonable potential to cause or contribute to a violation of a narrative
criterion, numeric WQBELs for dioxin or dioxin-like compounds should be included
in NPDES permits and should be expressed using a TEQ scheme” (Fed. Reg. Vol. 65,
No. 97, pages 31695-31696, May 18, 2000). This Order uses a TEQ scheme based on
a set of toxicity equivalency factors (TEFs) the World Health Organization developed
in 2005, and a set of bioaccumulation equivalency factors (BEFs) U.S. EPA
developed for the Great Lakes region (40 C.F.R. § 132, Appendix F) to convert the
concentration of any congener of dioxin or furan into an equivalent concentration of
2,3,7,8-tetrachlorinated dibenzo-p-dioxin (2,3,7,8-TCDD). Although the 2005 World

PERMANENTE PLANT NPDES No. CA0030210
Attachment F – Fact Sheet F-17
Health Organization scheme includes TEFs for dioxin-like PCBs, they are not
included in this Order’s TEQ scheme. The CTR has established a specific water
quality criterion for PCBs, and dioxin-like PCBs are included in the analysis of total
PCBs.
The CTR establishes a numeric water quality objective for 2,3,7,8-TCDD of
1.4 x 10-8 μg/L for the protection of human health when aquatic organisms are
consumed. This CTR criterion is used as a criterion for dioxin TEQ because
dioxin-TEQ represents a toxicity-weighted concentration equivalent to
2,3,7,8-TCDD, thus translating the narrative bioaccumulation objective into a
numeric criterion.
iii. Chronic Toxicity. The narrative toxicity objective (Basin Plan section 3.3.18) states,
“All waters shall be maintained free of toxic substances in concentrations that are
lethal to or that produce other detrimental responses in aquatic organisms…. There
shall be no chronic toxicity in ambient waters. Chronic toxicity is a detrimental
biological effect on growth rate, reproduction, fertilization success, larval
development, population abundance, community composition, or any other relevant
measure of the health of an organism, population, or community. Attainment of this
objective will be determined by analyses of indicator organisms, species diversity,
population density, growth anomalies, or toxicity tests…, or other methods selected
by the Water Board.”
For this Order, this narrative objective is translated into a numeric criterion of 1.0
chronic toxicity unit (TUc). At 1.0 TUc, there is no observable detrimental effect
when the indicator organism is exposed to 100 percent effluent; therefore, 1.0 TUc is
a direct translation of the narrative objective into a number. Moreover, in U.S. EPA’s
Technical Support Document for Water Quality-based Toxics Control (Technical
Support Document) (EPA/505/2-90-001, March 1991; see section 3.3.3, Step 3:
Decision Criteria for Permit Limit Development), U.S. EPA recommends that
1.0 TUc be used as a criterion continuous concentration (typically a four-day
average). It further states that reasonable potential is shown where an effluent is
projected to cause an excursion above the criterion continuous concentration. This
document applies here as guidance because it directly addresses effluent
characterization for toxicity.
iv. Temperature. Permanente Creek supports warm water and cold water habitat
beneficial uses; therefore, the temperature water quality objectives in Basin Plan
section 3.3.17 apply:
• The natural receiving water temperature of inland surface waters shall not
be altered unless it can be demonstrated to the satisfaction of the Regional
Board that such alteration in temperature does not adversely affect
beneficial uses.
• The temperature of any cold or warm freshwater habitat shall not be
increased by more than 5°F [degrees Fahrenheit] (2.8°C [degrees Celsius])
above natural receiving water temperature.
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment F – Fact Sheet F-18
b. Mercury Provisions Objectives. The Mercury Provisions specify water column criteria
for mercury depending on water body type and beneficial uses. Permanente Creek is a
flowing water body that supports cold freshwater habitat; warm freshwater habitat;
preservation of rare, threatened, or endangered species; and wildlife habitat beneficial
uses. Mercury Provisions section IV.D.2.b, Table 1, establish an annual average total
mercury criterion of 0.012 μg/L for Permanente Creek water.
c. California Toxics Rule Criteria. The CTR specifies numeric aquatic life and human
health criteria for numerous priority pollutants. These criteria apply to inland surface
waters and enclosed bays and estuaries. Some human health criteria are for consumption
of “water and organisms” and others are for consumption of “organisms only.” The CTR
criteria applicable to “water and organisms” apply to Permanente Creek because it is
considered a potential source of drinking water, as described in Fact Sheet section III.C.1,
above.
d. National Toxics Rule Criteria. The NTR establishes numeric aquatic life and human
health criteria for a number of toxic pollutants for San Francisco Bay waters upstream to
and including Suisun Bay and the Sacramento-San Joaquin Delta. The NTR criteria apply
to Permanente Creek.
e. Receiving Water Salinity. Basin Plan section 4.6.2 (like the CTR and NTR) states that
the salinity characteristics (i.e., freshwater versus saltwater) of the receiving water are to
be considered in determining the applicable water quality objectives. Freshwater criteria
apply to discharges to waters with salinities equal to or less than one part per thousand
(ppt) at least 95 percent of the time. Saltwater criteria apply to discharges to waters with
salinities equal to or greater than 10 ppt at least 95 percent of the time in a normal water
year. For discharges to waters with salinities between these two categories, or tidallyinfluenced
freshwaters that support estuarine beneficial uses, the water quality objectives
are the lower of the salt or freshwater objectives (the latter calculated based on ambient
hardness) for each substance.
Permanente Creek is an inland freshwater stream as confirmed by salinity data collected
in from 2014 through 2018. No salinity greater than 1 ppt was detected in any sample.
Permanente Creek is therefore classified as freshwater, and the reasonable potential
analysis and WQBELs are based on freshwater water quality criteria and objectives.
f. Receiving Water Hardness. Ambient hardness data are used to calculate freshwater
water quality objectives that are hardness dependent. The water quality objectives for this
Order are based on a hardness of 280 mg/L as CaCO3, which is the geometric mean of
observed hardness at the confluence of Wild Violet Creek and Permanente Creek
(Monitoring Location RSW-001A as defined in the Monitoring and Reporting Program).
3. Need for Water Quality-Based Effluent Limitations (Reasonable Potential Analysis)
Assessing whether a pollutant has reasonable potential to cause or contribute to exceedances
of a water quality objective is the fundamental step in determining whether a WQBEL is
required. The reasonable potential analysis presented below applies to Discharge Point
Nos. 001 and 007, where process wastewaters are actively generated and discharged. These
process wastewater discharges are subject to numeric WQBELs where reasonable potential is
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment F – Fact Sheet F-19
indicated. Stormwater discharges from Discharge Point Nos. 002 and 004 through 006 are
subject to narrative WQBELs.
a. Methodology. State Implementation Policy section 1.3 sets forth the methodology used
for this Order for assessing whether a priority pollutant has reasonable potential to exceed
a water quality objective. SIP section 1.3 applies to priority pollutants and is used here
for dioxin-TEQ, ammonia, total dissolved solids, turbidity, chloride, and phenols, as
guidance. The analysis begins with identifying the maximum effluent concentration
(MEC) observed for each pollutant based on available effluent concentration data and the
ambient background concentration (B). State Implementation Policy section 1.4.3 states
that ambient background concentrations are either the maximum ambient concentration
observed or, for water quality objectives intended to protect human health, the arithmetic
mean of observed concentrations. There are three triggers in determining reasonable
potential:
i. Trigger 1 is activated if the maximum effluent concentration is greater than or equal
to the lowest applicable water quality objective (MEC water quality objective).
ii. Trigger 2 is activated if the ambient background concentration observed in the
receiving water is greater than the water quality objective (B > water quality
objective) and the pollutant is detected in any effluent sample.
iii. Trigger 3 is activated if a review of other information indicates that a WQBEL is
needed to protect beneficial uses.
The Mercury Provisions (section IV.D.2.c) modify SIP section 1.3 for mercury. The
maximum effluent concentration and ambient background concentration are maximum
annual averages, calculated as the arithmetic mean over each calendar year, with nondetect
results estimated as half the method detection limit.
b. Effluent Data. The reasonable potential analysis for this Order is based on effluent data
from Discharge Point No. 001 that the Discharger collected from October 2017 through
July 2018, after the FTS was installed, for most inorganics, and from December 2014
through April 2017, the latest data available, for most organics. For Mercury, effluent
data from Discharge Point No. 001 collected from May 2014 through July 2018 are
considered because they are reasonably representative relative to the mercury water
quality objective and allow calculation of annual averages.
All the Facility’s process wastewaters, including those currently discharged from
Discharge Point No. 001, will be treated by the FTS and discharged from Discharge Point
Nos. 001 and 007. Therefore, while the reasonable potential analysis is based on data
from Discharge Point No. 001, the analysis conclusions and any resulting limits apply to
both Discharge Point Nos. 001 and 007.
.
c. Ambient Background Data. The reasonable potential analysis for this Order is based on
background data collected from May 2014 through July 2018 at Monitoring Location
RSW-001A. This location was chosen based on its accessibility, geological
appropriateness, likely perennial flow, and lack of chemical influences from the Facility
or other land uses (Background Monitoring Locations Plan and Reporting, Water Code

section 13267 Order No. R2-2013-1005, Order Item No. 6, Golder Associates, March 6,
2013).
d. Reasonable Potential Analysis. The maximum effluent concentrations, most stringent
applicable water quality criteria and objectives, and ambient background concentrations
used in the analysis are presented in the following table, along with the reasonable
potential analysis results (yes or no) for each pollutant. The pollutants that exhibit
reasonable potential are antimony, chromium (VI), and selenium.
We find that chromium (VI) has a reasonable potential to be discharged at a
concentration that could cause or contribute to an exceedance of water quality objectives
in Permanente Creek by Trigger 3, above, based on a combination of factors. While
chromium (VI) has not been discharged in excess of its water quality objectives since the
Discharger installed the FTS, sufficient information is not yet available to fully assess
FTS performance and reliability. The Discharger has operated the FTS for less than
twelve months during two normal rainy seasons (the Discharger does not operate the FTS
during the dry season). The FTS is complex and, while capable of meeting stringent
limits for metals, has not been used to meet effluent limitations as stringent as those in
this Order or the previous order at other sites. Standard operating procedures are therefore
unavailable from the manufacturer and the Discharger has had to refine its treatment
operations to meet these limits. Chromium (VI) is potentially toxic if insufficiently
treated, and the discharge receives no dilution. Moreover, chromium (VI) is a potential
drinking water contaminant, and Permanente Creek’s beneficial uses include municipal
supply and groundwater recharge (see Fact Sheet Table F-5), which are of particular
community concern. Also, the Discharger has a history of compliance problems, despite
its improved performance.

Footnotes:
[1] The maximum effluent concentration and ambient background concentration are the actual detected concentrations unless
preceded by a “<” sign, in which case the value shown is the minimum detection level (DL).
[2] The maximum effluent concentration or ambient background concentration is “Unavailable” when there are no monitoring data
for the constituent.
[3] RPA Results = Yes, if MEC ≥ WQC, B > WQC and MEC is detected, or Trigger 3
= No, if MEC and B are < WQC or all effluent data are undetected
= Undetermined (U), if no criteria have been promulgated or data are insufficient.
[4] The Mercury Provisions supersede Basin Plan Table 3-4 (see Fact Sheet § III.C.9). In accordance with the Mercury Provisions,
the water quality objective (C), MEC, and B are annual averages calculated as described in Fact Sheet section IV.C.3.a.
e. Acute Toxicity. Basin Plan section 4.5.5.3.1 requires acute toxicity monitoring and
limitations, implying there is reasonable potential for the discharge to cause or contribute
to exceedances of the acute toxicity water quality objective.
f. Chronic Toxicity. From October 2017 through April 2018, the Discharger obtained four
chronic toxicity results from Monitoring Location EFF-001 that were representative of
the discharge. (Results obtained during January, March, and April 2018 are omitted as
unrepresentative because the FTP’s peroxide injection system was not operating correctly
during those months.) None of those results exceed 1.0 TUc. Therefore, none exceeded
the translated chronic toxicity water quality objective of 1.0 TUc (see Fact Sheet section
IV.C.2.a.iii), and there is no reasonable potential for the discharge to cause or contribute
to exceedances of the chronic toxicity water quality objective.
g. Temperature. Permanente Creek supports warm and cold water habitat beneficial uses;
Basin Plan temperature objectives therefore apply. Temperature data from effluent
Monitoring Location EFF-001 and receiving water Monitoring Locations RSW-001,
001A, and 002 through 004 indicate that Facility discharges did not impact receiving
water temperature before or after the FTS was installed. The Monitoring and Reporting
Program requires monitoring of background, effluent, and downstream receiving water
temperatures to support future reasonable potential analysis.
4. Water Quality-Based Effluent Limitation Calculations
For Discharge Point Nos. 001 and 007, numeric WQBELs were developed for the pollutants
determined to have reasonable potential to cause or contribute to exceedances of water
quality objectives. Except for acute toxicity (discussed below), these WQBELs are based on
the procedure specified in SIP section 1.4, as required for priority pollutants and as guidance
for the other pollutants.
WQBELs for Discharge Point Nos. 002 and 004 through 006 are narrative based on Basin
Plan section 4.8 and 40 C.F.R. part 122.44(k). These WQBELs are set forth in
Provision VI.A.3 and Attachment S, as amended. U.S. EPA’s NPDES Permit Writers’
Manual (EPA-833-K-10-001, September 2010, page 9-4) indicates that numeric effluent
limits are infeasible “when the types of pollutants vary greatly over time.” For many
pollutants at Discharge Point Nos. 002 and 004 through 006, numeric WQBELs are
infeasible because the pollutants in stormwater vary greatly over time. Storms occur
irregularly, unpredictably, uncontrollably, and occasionally in large volumes for short
periods, so the resulting types of pollutants mobilized by storm runoff vary greatly.

a. Dilution Credits. SIP section 1.4.2 allows dilution credits under certain circumstances.
Because neither Discharge Point No. 001 nor 007 is submerged, has a diffuser, or
achieves any dilution, no dilution credit is used in the calculation of WQBELs.

5. Acute Toxicity
This Order includes acute toxicity effluent limitations based on Basin Plan Table 4-3. Based
on Basin Plan section 3.3.20, if the Discharger can demonstrate that ammonia causes acute
toxicity exceeding the acute toxicity limitations in this Order, and that the ammonia in the
discharge complies with the ammonia effluent limitations in this Order, then such toxicity
does not constitute a violation of the effluent limitations for whole effluent acute toxicity.
D. Discharger Requirement Considerations
1. Anti-backsliding. This Order complies with the anti-backsliding provisions of CWA
sections 402(o) and 303(d)(4) and 40 C.F.R. section 122.44(l), which generally require
effluent limitations in a reissued permit to be as stringent as those in the previous order. The
requirements of this Order are at least as stringent as those in the previous order, except for
WQBELs for nickel, mercury, thallium, TDS, and turbidity at Discharge Point No. 001, and
technology-based requirements for turbidity at Discharge Point Nos. 002, 004, and 005.
a. This Order does not retain the previous order’s nickel, mercury, thallium, TDS, or
turbidity WQBELs at Discharge Point No. 001 because effluent data for those pollutants
no longer indicate reasonable potential to exceed of water quality objectives. Not
retaining those limits is consistent with State Water Board Order No. WQ 2001-16.
b. This Order does not retain the previous order’s technology-based effluent limit for
turbidity at Discharge Point Nos. 002, 004, and 005 because that limit was based on
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment F – Fact Sheet F-26
inapplicable guidance. The Discharger enrolled the Facility under the General Waste
Discharge Requirements for Discharges of Process Wastewaters from Aggregate Mining,
Sand Washing, and Sand Offloading Facilities to Surface Waters (NPDES General
Permit No. CAG982001) (Sand and Gravel Permit), which imposed a turbidity limit
based on aggregate mining facilities within San Francisco Bay Region. The previous
order imposed the same turbidity limit based on the Sand and Gravel Permit. However,
the discharges should have been subject to the Effluent Limitations Guidelines for cement
manufacturing, as discussed in Fact Sheet section IV.B.1. Backsliding is therefore
permissible under CWA section 402(o)(2)(B)(ii) and 40 C.F.R. section 122.44(l).
2. Antidegradation. This Order complies with the antidegradation provisions of 40 C.F.R.
section 131.12 and State Water Board Resolution No. 68-16. It does not authorize lowering
water quality as compared to the level of discharge authorized in the previous order, which is
the baseline by which to measure whether degradation will occur. This Order does not allow
for a reduced level of treatment or increased volume of discharge, nor does it increase effluent
limitations relative to the previous order.
3. Stringency of Requirements for Individual Pollutants. This Order contains both
technology-based effluent limits and WQBELs for individual pollutants. The technologybased
requirements implement minimum, applicable federal technology-based requirements.
In addition, this Order contains more stringent effluent limitations as necessary to meet water
quality standards, including selenium effluent limitations intended to achieve water quality
standards for selenium in Permanente Creek, as discussed in Fact Sheet section III.D.
Collectively, this Order’s restrictions on individual pollutants are no more stringent than
required to implement CWA requirements.
This Order’s WQBELs have been derived to implement water quality objectives that protect
beneficial uses. The beneficial uses and water quality objectives have been approved
pursuant to federal law and are the applicable federal water quality standards. To the extent
that WQBELs were derived from the CTR, the CTR is the applicable standard pursuant to
40 C.F.R. section 131.38. The procedures for calculating these WQBELs are based on the
CTR, as implemented in accordance with the SIP, which U.S. EPA approved on May 18,
2000. U.S. EPA approved most Basin Plan beneficial uses and water quality objectives prior
to May 30, 2000. Beneficial uses and water quality objectives submitted to U.S. EPA prior to
May 30, 2000, but not approved by U.S. EPA before that date, are nonetheless “applicable
water quality standards for purposes of the CWA” pursuant to 40 C.F.R. section
131.21(c)(1). U.S. EPA approved the remaining beneficial uses and water quality objectives,
so they are applicable water quality standards pursuant to 40 C.F.R. section 131.21(c)(2).
V. RATIONALE FOR RECEIVING WATER LIMITATIONS
The receiving water limitations in sections V.A.1 and V.A.2 of this Order are based on Basin Plan
narrative and numeric water quality objectives. The receiving water limitation in section V.A.3 of
this Order requires compliance with water quality standards.
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment F – Fact Sheet F-27
VI. RATIONALE FOR PROVISIONS
A. Standard Provisions
Attachment D contains standard provisions that apply to all NPDES permits in accordance with
40 C.F.R. section 122.41 and additional conditions applicable to specific categories of permits in
accordance with 40 C.F.R. section 122.42. The Discharger must comply with these provisions.
The conditions set forth in 40 C.F.R. sections 122.41(a)(1) and (b) through (n) apply to all stateissued
NPDES permits and must be incorporated into the permits either expressly or by
reference.
Attachment G contains regional standard provisions that supplement the federal standard
provisions in Attachment D. In accordance with 40 C.F.R. section 123.25(a)(12), states may omit
or modify the federal standard conditions to impose more stringent requirements. This Order
omits federal conditions that address enforcement authority specified in 40 C.F.R. sections
122.41(j)(5) and (k)(2) because the State’s enforcement authority under the Water Code is more
stringent. In lieu of these conditions, this Order incorporates Water Code section 13387(e) by
reference.
Attachment S contains stormwater provisions consistent with the State Water Board’s General
Permit for Stormwater Discharges Associated with Industrial Activities (NPDES No.
CAS000001) (Industrial General Permit), including requirements for the Discharger to prepare a
Stormwater Pollution Prevention Plan, to evaluate BMP performance using stormwater action
levels (stormwater action levels are not effluent limitations), and to submit an annual stormwater
report. This Order modifies Attachment S to include stormwater action levels appropriate for this
Facility. For each toxic pollutant with an effluent limit at Discharge Point Nos. 001 and 007 but
no stormwater action level in the Industrial General Permit or U.S.EPA’s 2015 Multi-Sector
General Permit for Stormwater Discharges Associated with Industrial Activity (MSGP), this
Order establishes the lowest acute water quality objective as the stormwater action level. It does
not retain the stormwater action level for conductivity of 200 micromhos per centimeter
(μmhos/cm) from the previous order because, based on monitoring data collected at Monitoring
Location RSW-001A, background conductivity exceeds the stormwater action level. Electrical
conductivity at Monitoring Location RSW-001A ranged from 279 to 630 μmhos/cm with an
average value of 492 μmhos/cm.
B. Monitoring and Reporting
Pursuant to 40 C.F.R. section 122.48, NPDES permits must specify requirements for recording
and reporting monitoring results. Water Code sections 13267 and 13383, and 40 C.F.R. sections
122.41(h) and (j), authorize the Regional Water Board to require technical and monitoring
reports. This Order establishes monitoring and reporting requirements, contained in the
Monitoring and Reporting Program (Attachment E), that implement federal and State
requirements. For more background regarding these requirements, see Fact Sheet section VII.
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment F – Fact Sheet F-28
C. Special Provisions
1. Reopener Provisions
These provisions are based on 40 C.F.R. sections 122.62 and 122.63 and allow modification
of this Order and its effluent limitations as necessary in response to updated water quality
objectives, regulations, or other new and relevant information that may become available in
the future, and other circumstances as allowed by law.
2. Effluent Characterization Study and Report
This Order does not include effluent limitations for priority pollutants that do not
demonstrate reasonable potential, but this provision requires the Discharger to evaluate
monitoring data to verify that the reasonable potential analysis conclusions of this Order
remain valid. This requirement is authorized pursuant to 40 C.F.R. section 122.41(h) and
Water Code section 13267, and is necessary to inform the next permit reissuance and to
ensure that the Discharger takes timely steps in response to any unanticipated change in
effluent quality during the term of this Order.
3. Pollutant Minimization Program
This provision is based on SIP section 2.4.5.
4. Receiving Water Data Reporting
This Order requires the Discharger to upload receiving water data to the California
Environmental Data Exchange Network (CEDEN) to the extent that CEDEN accommodates
the data type. This requirement ensures that the public can access these data through
CEDEN’s database, and that the State and Regional Water Boards can use these data to
evaluate whether Permanente Creek meets water quality standards pursuant to CWA section
303(d).
5. Dry Season Discharge Requirements
This provision is necessary to maintain existing aquatic habitat beneficial uses between
Discharge Point Nos. 001 and 007. Aquatic habitat beneficial uses within this reach include
cold freshwater habitat (e.g., trout) and preservation of rare, threatened, or endangered
species (e.g., California red-legged frogs).
6. Selenium in Fish Tissue Reasonable Potential Study
This provision may be necessary to conduct future reasonable potential analyses for the
Discharger’s selenium discharges to Permanente Creek because U.S. EPA has proposed new
water quality standards for California for selenium in freshwater (Water Quality Standards;
Establishment of a Numeric Criterion for Selenium for the State of California, Fed. Reg.
Vol. 83, No. 239, December 13, 2018, pages 64059-64078). If U.S. EPA or the State of
California promulgates these draft standards (or similar standards), subsequent reasonable
potential analyses would need to be based on the new standards. As drafted, the proposed
standards would establish tiered water quality criteria. Proposed fish tissue criteria would
supersede water column criteria and could serve as the basis for a reasonable potential
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment F – Fact Sheet F-29
analysis. The required study would be conducted in phases. The requirements recognize and
reflect the potentially limited availability of fish to sample and analyze.
VII. MONITORING AND REPORTING PROGRAM (MRP)
Attachment E contains the MRP for this Order. It specifies sampling stations, pollutants to be
monitored (including all parameters for which effluent limitations are specified), monitoring
frequencies, and reporting requirements. The following provides the rationale for the MRP
requirements.
A. MRP Requirements Rationale
The MRP’s monitoring and reporting requirements are based on California Water Code section
13267 and are necessary to inform the next permit reissuance; to collect data needed to evaluate
progress toward resolving the selenium impairment of Permanente Creek, as discussed in Fact
Sheet section III.D; and to ensure that any potential toxicity in Permanente Creek other than
pesticides is identified and resolved, as discussed in Fact Sheet section III.D. The reports
required by the MRP are necessary to accomplish the foregoing and to ensure compliance with
this Order. The Discharger is subject to these requirements because it owns and operates the
Facility, which discharges wastes subject to this Order. The burden, including costs, of the
monitoring and reporting, bears a reasonable relationship to the need to achieve water quality
standards for selenium and aquatic toxicity in Permanente Creek, and to ensure permit
compliance.
1. Effluent Monitoring. Effluent flow monitoring is necessary at Monitoring Locations
EFF-001 and EFF-007 to evaluate compliance with Prohibition III.B and to understand
Facility operations. Effluent flow monitoring is necessary at Monitoring Locations EFF-002,
EFF-004, EFF-005, and EFF-006 to evaluate the Discharger’s management of Facility
stormwater. Monitoring for the other parameters is necessary at Monitoring Locations
EFF-001, EFF-002, EFF-004, EFF-005, EFF-006, and EFF-007 to evaluate compliance with
this Order’s effluent limitations and to conduct future reasonable potential analyses.
Monitoring is also needed at Monitoring Locations EFF-002, EFF 004, EFF-005, and
EFF 006 to evaluate the effectiveness of the Discharger’s stormwater BMPs by comparing
discharge concentrations with stormwater action levels.
2. Receiving Water Monitoring. Receiving water monitoring is necessary to characterize the
receiving water (e.g., to provide background values for future reasonable potential analyses)
and the effects of the discharges on the receiving water (i.e., to determine compliance with
receiving water limitations). Monitoring Location RSW-001A represents background water
quality based on the Background Monitoring Report (Golder Associates, March 22, 2013),
which found that Monitoring Location RSW-001A is unaffected by Facility operations, is
accessible for sampling, and has similar geologic conditions as the discharge locations.
Monitoring Locations RSW-001, RSW-002, and RSW-004 represent conditions immediately
downstream of the discharge points. Monitoring Locations RSW-005, RSW-006, and
RSW-007 represent conditions farther downstream of the Facility.
By including Monitoring Locations RSW-005, RSW-006, and RSW-007 within this Order’s
MRP, the Order updates receiving water monitoring requirements the Executive Officer
imposed through an August 1, 2018, order to provide technical information pursuant to
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment F – Fact Sheet F-30
Water Code section 13267. In doing so, this Order contains monitoring and reporting
requirements to allow the Regional Water Board to evaluate progress toward resolving the
selenium impairment of Permanente Creek.
3. Toxicity Testing. Acute toxicity tests are necessary to evaluate compliance with acute
toxicity effluent limitations. Chronic toxicity tests are necessary for future reasonable
potential analysis and to evaluate whether chronic toxicity triggers the need for a Toxicity
Reduction Evaluation. By including chloride, total hardness as CaCO3, sulfate, chronic
toxicity, and trace metals monitoring at Monitoring Locations RSW-004 and RSW-005
within this Order’s MRP, the Order updates receiving water monitoring requirements the
Executive Officer imposed through an August 1, 2018, order to provide technical information
pursuant to Water Code section 13267. In doing so, this Order contains monitoring and
reporting requirements to allow the Regional Water Board to evaluate progress toward
resolving the toxicity impairment of Permanente Creek.
4. Other Monitoring Requirements. Pursuant to CWA section 308, U.S. EPA requires major
and selected minor dischargers to participate in a Discharge Monitoring Report-Quality
Assurance (DMR-QA) Study Program. The program annually evaluates the analytical
abilities of laboratories that perform or support NPDES permit-required monitoring. The
program applies to discharger laboratories and contract laboratories. There are two options to
comply: (1) dischargers can obtain and analyze DMR-QA samples, or (2) pursuant to a
waiver U.S. EPA issued to the State Water Board, dischargers can submit results from the
most recent Water Pollution Performance Evaluation Study. Dischargers must submit results
annually to the State Water Board, which then forwards the results to U.S. EPA.

REGIONAL STANDARD PROVISIONS, AND MONITORING AND
REPORTING REQUIREMENTS
APPLICABILITY
This document supplements the requirements of Federal Standard Provisions (Attachment D). For
clarity, these provisions are arranged using to the same headings as those used in Attachment D.
I. STANDARD PROVISIONS – PERMIT COMPLIANCE
A. Duty to Comply – Not Supplemented
B. Need to Halt or Reduce Activity Not a Defense – Not Supplemented
C. Duty to Mitigate – Supplement to Attachment D, Provision I.C.
1. Contingency Plan. The Discharger shall maintain a Contingency Plan as prudent in
accordance with current facility emergency planning. The Contingency Plan shall describe
procedures to ensure that existing facilities remain in, or are rapidly returned to, operation in
the event of a process failure or emergency incident, such as employee strike, strike by
suppliers of chemicals or maintenance services, power outage, vandalism, earthquake, or fire.
The Discharger may combine the Contingency Plan and Spill Prevention Plan (see
Provision I.C.2, below) into one document. In accordance with Regional Water Board
Resolution No. 74-10, discharge in violation of the permit where the Discharger has failed to
develop and implement a Contingency Plan as described below may be the basis for
considering the discharge a willful and negligent violation of the permit pursuant to
California Water Code section 13387. The Contingency Plan shall, at a minimum, provide
for the following:
a. Sufficient personnel for continued facility operation and maintenance during employee
strikes or strikes against contractors providing services;
b. Maintenance of adequate chemicals or other supplies, and spare parts necessary for
continued facility operations;
c. Emergency standby power;
d. Protection against vandalism;
e. Expeditious action to repair failures of, or damage to, equipment, including any sewer
lines;
f. Reporting of spills and discharges of untreated or inadequately treated wastes, including
measures taken to clean up the effects of such discharges; and
g. Maintenance, replacement, and surveillance of physical condition of equipment and
facilities, including any sewer lines.

accidental discharges and to minimize the effects of any such discharges. The Spill
Prevention Plan shall do the following:
a. Identify the possible sources of accidental discharge, untreated or partially-treated waste
bypass, and polluted drainage;
b. State when current facilities and procedures became operational and evaluate their
effectiveness; and
c. Predict the effectiveness of any proposed facilities and procedures and provide an
implementation schedule with interim and final dates when the proposed facilities and
procedures will be constructed, implemented, or operational.
D. Proper Operation and Maintenance – Supplement to Attachment D, Provision I.D
1. Operation and Maintenance Manual. The Discharger shall maintain an Operation and
Maintenance Manual to provide the plant and regulatory personnel with a source of
information describing all equipment, recommended operational strategies, process control
monitoring, and maintenance activities. To remain a useful and relevant document, the
Operation and Maintenance Manual shall be kept updated to reflect significant changes in
treatment facility equipment and operational practices. The Operation and Maintenance
Manual shall be maintained in usable condition and be available for reference and use by all
relevant personnel and Regional Water Board staff.
2. Wastewater Facilities Status Report. The Discharger shall maintain a Wastewater Facilities
Status Report and regularly review, revise, or update it, as necessary. This report shall
document how the Discharger operates and maintains its wastewater collection, treatment,
and disposal facilities to ensure that all facilities are adequately staffed, supervised, financed,
operated, maintained, repaired, and upgraded as necessary to provide adequate and reliable
transport, treatment, and disposal of all wastewater from both existing and planned future
wastewater sources under the Discharger’s service responsibilities.

II. STANDARD PROVISIONS – PERMIT ACTION – Not Supplemented
III.STANDARD PROVISIONS – MONITORING
A. Sampling and Analyses – Supplement to Attachment D, Provisions III.A and III.B
1. Certified Laboratories. Water and waste analyses shall be performed by a laboratory certified
for these analyses in accordance with California Water Code section 13176.
2. Minimum Levels. For the 126 priority pollutants, the Discharger should use the analytical
methods listed in Table B unless the Monitoring and Reporting Program (MRP,
Attachment E) requires a particular method or minimum level (ML). All monitoring
instruments and equipment shall be properly calibrated and maintained to ensure accuracy of
measurements.
3. Monitoring Frequency. The MRP specifies the minimum sampling and analysis schedule.
a. Sample Collection Timing
i. The Discharger shall collect influent samples on varying days selected at random
and shall not include any plant recirculation or other sidestream wastes, unless
otherwise stipulated in the MRP. The Executive Officer may approve an alternative
influent sampling plan if it is representative of plant influent and complies with all
other permit requirements.
ii. The Discharger shall collect effluent samples on days coincident with influent
sampling, unless otherwise stipulated by the MRP. If influent sampling is not
required, the Discharger shall collect effluent samples on varying days selected at
random, unless otherwise stipulated in the MRP. The Executive Officer may approve
an alternative effluent sampling plan if it is representative of plant discharge and in
compliance with all other permit requirements.
iii. The Discharger shall collect effluent grab samples during periods of daytime
maximum peak flows (or peak flows through secondary treatment units for facilities
that recycle effluent).
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment G – Regional Standard Provisions G-4
iv. Effluent sampling for conventional pollutants shall occur on at least one day of any
multiple-day bioassay the MRP requires. During the course of the bioassay, on at
least one day, the Discharger shall collect and retain samples of the discharge. In the
event that a bioassay result does not comply with effluent limitations, the Discharger
shall analyze the retained samples for pollutants that could be toxic to aquatic life
and for which it has effluent limitations.
(a) The Discharger shall perform bioassays on final effluent samples; when chlorine
is used for disinfection, bioassays shall be performed on effluent after
chlorination and dechlorination; and
(b) The Discharger shall analyze for total ammonia nitrogen and calculate the
amount of un-ionized ammonia whenever test results fail to meet effluent
limitations.
b. Conditions Triggering Accelerated Monitoring
i. Average Monthly Effluent Limitation Exceedance. If the results from two
consecutive samples of a constituent monitored in a particular month exceed the
average monthly effluent limitation for any parameter (or if the required sampling
frequency is once per month or less and the monthly sample exceeds the average
monthly effluent limitation), the Discharger shall, within 24 hours after the results
are received, increase its sampling frequency to daily until the results from the
additional sampling show that the parameter complies with the average monthly
effluent limitation.
ii. Maximum Daily Effluent Limitation Exceedance. If a sample result exceeds a
maximum daily effluent limitation, the Discharger shall, within 24 hours after the
result is received, increase its sampling frequency to daily until the results from two
samples collected on consecutive days show compliance with the maximum daily
effluent limitation.
iii. Acute Toxicity. If final or intermediate results of an acute bioassay indicate a
violation or threatened violation (e.g., the percentage of surviving test organisms of
any single acute bioassay is less than 70 percent), the Discharger shall initiate a new
test as soon as practical or as described in applicable State Water Board plan
provisions that become effective after adoption of these Regional Standard
Provisions. The Discharger shall investigate the cause of the mortalities and report
its findings in the next self-monitoring report.
iv. Chlorine. The Discharger shall calibrate chlorine residual analyzers against grab
samples as frequently as necessary to maintain accurate control and reliable
operation. If an effluent violation is detected, the Discharger shall collect grab
samples at least every 30 minutes until compliance with the limitation is achieved,
unless the Discharger monitors chlorine residual continuously. In such cases, the
Discharger shall continue to conduct continuous monitoring.
v. Bypass. Except as indicated below, if a Discharger bypasses any portion of its
treatment facility, it shall monitor flows and collect samples at affected discharge
points and analyze samples for all constituents with effluent limitations on a daily
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment G – Regional Standard Provisions G-5
basis for the duration of the bypass. The Discharger need not accelerate chronic
toxicity monitoring. The Discharger also need not collect and analyze samples for
mercury, dioxin-TEQ, and PCBs after the first day of the bypass. The Discharger
may satisfy the accelerated acute toxicity monitoring requirement by conducting a
flow-through test or static renewal test that captures the duration of the bypass
(regardless of the method specified in the MRP). If bypassing disinfection units only,
the Discharger shall only monitor bacteria indicators daily.
(a) Bypass for Essential Maintenance. If a Discharger bypasses a treatment unit
for essential maintenance pursuant to Attachment D section I.G.2, the Executive
Officer may reduce the accelerated monitoring requirements above if the
Discharger (i) monitors effluent at affected discharge points on the first day of
the bypass for all constituents with effluent limitations, except chronic toxicity;
and (ii) identifies and implements measures to ensure that the bypass will
continue to comply with effluent limitations.
(b) Approved Wet Weather Bypasses. If a Discharger bypasses a treatment unit or
permitted outfall during wet weather with Executive Officer approval pursuant to
Attachment D section I.G.4, the Discharger shall monitor flows and collect and
retain samples for affected discharge points on a daily basis for the duration of
the bypass. The Discharger shall analyze daily for TSS using 24-hour composites
(or more frequent increments) and for bacteria indicators with effluent
limitations using grab samples. If TSS exceeds 45 mg/L in any composite
sample, the Discharger shall also analyze daily the retained samples for all other
constituents with effluent limitations, except oil and grease, mercury, PCBs,
dioxin-TEQ, and acute and chronic toxicity. Additionally, at least once each
year, the Discharger shall analyze the retained samples for one approved bypass
for all other constituents with effluent limitations, except oil and grease,
mercury, PCBs, dioxin-TEQ, and acute and chronic toxicity. This monitoring
shall be in addition to the minimum monitoring specified in the MRP.

LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment G – Regional Standard Provisions G-9
b. Compliance Evaluation Summary. Each self-monitoring report shall include a
compliance evaluation summary that addresses each parameter for which the permit
specifies effluent limitations, the number of samples taken during the monitoring period,
and the number of samples that exceed the effluent limitations.
c. More Frequent Monitoring. If the Discharger monitors any pollutant more frequently
than required by the MRP, the Discharger shall include the results of such monitoring in
the calculation and reporting of the data submitted in the self-monitoring report.
d. Analysis Results
i. Tabulation. Each self-monitoring report shall include tabulations of all required
analyses and observations, including parameters, dates, times, sample stations, types
of samples, test results, method detection limits, method minimum levels, and
method reporting levels (if applicable), signed by the laboratory director or other
responsible official.
ii. Multiple Samples. Unless the MRP specifies otherwise, when determining
compliance with effluent limitations (other than instantaneous effluent limitations)
and more than one sample result is available, the Discharger shall compute the
arithmetic mean. If the data set contains one or more results that are “Detected, but
Not Quantified (DNQ) or “Not Detected” (ND), the Discharger shall instead
compute the median in accordance with the following procedure:
(a) The data set shall be ranked from low to high, reported ND determinations
lowest, DNQ determinations next, followed by quantified values (if any). The
order of the individual ND or DNQ determinations is unimportant.
(b) The median of the data set shall be determined. If the data set has an odd number
of data points, the median is the middle value. If the data set has an even number
of data points, the median is the average of the two values around the middle,
unless one or both of these values is ND or DNQ, in which case the median shall
be the lower of the two results (where DNQ is lower than a quantified value and
ND is lower than DNQ).
iii. Duplicate Samples. The Discharger shall report the average of duplicate sample
analyses when reporting for a single sample result (or the median if one or more
of the duplicates is DNQ or ND [see Provision V.C.1.c.ii, above]). For bacteria
indicators, the Discharger shall report the geometric mean of the duplicate
analyses.
iv. Dioxin-TEQ. The Discharger shall report for each dioxin and furan congener the
analytical results of effluent monitoring, including the reporting level, the method
detection limit, and the measured concentration. The Discharger shall report all
measured values of individual congeners, including data qualifiers. When calculating
dioxin-TEQ, the Discharger shall set congener concentrations below the minimum
levels (MLs) to zero. The Discharger shall calculate and report dioxin-TEQ using the
following formula, where the MLs, toxicity equivalency factors (TEFs), and
bioaccumulation equivalency factors (BEFs) are as provided in Table A:

antilogarithms. The geometric mean can be calculated with either of the following equations:
Geometric Mean
Or
Where “N” is the number of data points for the period analyzed and “C” is the concentration
for each of the “N” data points.
2. Mass Emission Rate. The rate of discharge expressed in mass. The mass emission rate is
obtained from the following calculation for any calendar day:
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment G – Regional Standard Provisions G-14
In which “N” is the number of samples analyzed in any calendar day and “Qi” and “Ci” are
the flow rate (MGD) and the constituent concentration (mg/L) associated with each of the
“N” grab samples that may be taken in any calendar day. If a composite sample is taken, “Ci”
is the concentration measured in the composite sample and “Qi” is the average flow rate
occurring during the period over which the samples are composited. The daily concentration
of a constituent measured over any calendar day shall be determined from the flow-weighted
average of the same constituent in the combined waste streams as follows:
In which “N” is the number of component waste streams and “Q” and “C” are the flow rate
(MGD) and the constituent concentration (mg/L) associated with each of the “N” waste
streams. “Qt” is the total flow rate of the combined waste streams.
3. Removal Efficiency. The ratio of pollutants removed by the treatment facilities to pollutants
entering the treatment facilities (expressed as a percentage). The Discharger shall determine
removal efficiencies using monthly averages (by calendar month unless otherwise specified)
of pollutant concentration of influent and effluent samples collected at about the same time
and using the following equation (or its equivalent):
B. Blending – the practice of bypassing biological treatment units and recombining the bypass
wastewater with biologically-treated wastewater.
C. Composite Sample – a sample composed of individual grab samples collected manually or by
an automatic sampling device on the basis of time or flow as specified in the MRP. For flowbased
composites, the proportion of each grab sample included in the composite sample shall be
within plus or minus five percent (+/-5%) of the representative flow of the waste stream being
measured at the time of grab sample collection. Alternatively, equal volume grab samples may
be individually analyzed with the flow-weighted average calculated by averaging flow-weighted
ratios of each grab sample analytical result. Grab samples comprising time-based composite
samples shall be collected at intervals not greater than those specified in the MRP. The quantity
of each grab sample comprising a time-based composite sample shall be a set of flow
proportional volumes as specified in the MRP. If a particular time-based or flow-based
composite sampling protocol is not specified in the MRP, the Discharger shall determine and
implement the most representative protocol.
D. Duplicate Sample – a second sample taken from the same source and at the same time as an
initial sample (such samples are typically analyzed identically to measure analytical variability).
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment G – Regional Standard Provisions G-15
E. Grab Sample – an individual sample collected during a short period not exceeding 15 minutes.
Grab samples represent only the condition that exists at the time the sample is collected.
F. Overflow – the intentional or unintentional spilling or forcing out of untreated or partiallytreated
waste from a transport system (e.g., through manholes, at pump stations, or at collection
points) upstream of the treatment plant headworks or from any part of a treatment plant.
G. Priority Pollutants – those constituents referred to in 40 C.F.R. part 122 as promulgated in the
Federal Register, Vol. 65, No. 97, Thursday, May 18, 2000, also known as the California Toxics
Rule.

2. The frequency, times of day, or conditions when the BMP is scheduled for implementation;
3. The locations within each area of industrial activity or industrial pollutant source where the
BMP shall be implemented;
4. The individual responsible for implementing the BMP;
5. The procedures, including maintenance procedures, and instructions to implement the BMP
effectively; and
6. The equipment and tools necessary to implement the BMP effectively.
I. Annual Comprehensive Facility Compliance Evaluation. The Discharger shall conduct one
annual facility evaluation for each reporting year (July 1 to June 30). If the Discharger conducts
an annual evaluation fewer than 8 months, or more than 16 months, after it conducts the previous
annual evaluation, it shall document the justification for doing so. The Discharger shall revise the
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment S – Stormwater Provisions S-7
SWPPP, as appropriate, and implement the revisions within 90 days of the annual evaluation. At
a minimum, the annual evaluations shall consist of the following:
1. A review of all sampling, visual observation, and inspection records conducted during the
previous reporting year;
2. An inspection of all areas of industrial activity and associated potential pollutant sources for
evidence of, or the potential for, pollutants entering the stormwater conveyance system;
3. An inspection of all drainage areas previously identified as having no exposure to industrial
activities and materials;
4. An inspection of equipment needed to implement the BMPs; and
5. An assessment of any other factors needed to comply with the requirements of the Annual
Stormwater Report (see Provision III.A, below).
II. STANDARD PROVISIONS – MONITORING
A. Visual Observations
1. Monthly Visual Observations
a. At least once per month, the Discharger shall visually observe each drainage area for the
following:
i. The presence or indication of prior, current, or potential unauthorized non-stormwater
discharges and their sources;
ii. Authorized non-stormwater discharges, sources, and associated BMPs; and
iii. Outdoor industrial equipment and storage areas, outdoor industrial activities areas,
BMPs, and all other potential sources of industrial pollutants.
b. The monthly visual observations shall be conducted during daylight hours of scheduled
facility operating hours and on days without precipitation.
c. The Discharger shall provide an explanation in the Annual Stormwater Report for
uncompleted monthly visual observations (see Provision III.A, below).
2. Sampling Event Visual Observations. Sampling event visual observations shall be
conducted at the same time sampling occurs at a discharge location. At each discharge
location where a sample is obtained, the Discharger shall observe the discharge of
stormwater associated with industrial activity.
a. The Discharger shall ensure that visual observations of stormwater discharged from
containment sources (e.g., secondary containment or storage ponds) are conducted at the
time that the discharge is sampled.

PERMANENTE PLANT NPDES No. CA0030210
Attachment S – Stormwater Provisions S-8
b. If the Discharger employs volume-based or flow-based treatment BMPs, it shall sample
any bypass that occurs while the visual observations and sampling of stormwater
discharges are conducted.
c. The Discharger shall visually observe and record the presence or absence of floating and
suspended materials, oil and grease, discolorations, turbidity, odors, trash/debris, and
sources of any discharged pollutants.
d. If a discharge location is not visually observed during the sampling event, the Discharger
shall record which discharge locations were not observed during sampling or that there
was no discharge from the discharge location.
e. The Discharger shall provide an explanation in the Annual Stormwater Report for
uncompleted sampling event visual observations (see Provision III.A, below).
3. Visual Observation Records. The Discharger shall maintain records of all visual
observations. Records shall include the date, approximate time, locations observed, presence
and probable source of any observed pollutants, name of persons who conducted the
observations, and any response actions and/or additional SWPPP revisions necessary in
response to the visual observations.
4. SWPPP Revisions. The Discharger shall revise its BMPs as necessary when the visual
observations indicate pollutant sources have not been adequately addressed.
B. Sampling and Analysis
1. The Discharger shall collect and analyze stormwater samples as specified in the MRP.
2. Samples shall be (i) representative of stormwater associated with industrial activities and any
commingled authorized non-stormwater dischargers; or (ii) associated with the discharge of
contained stormwater.
3. On a facility-specific basis, the Discharger shall also analyze additional parameters that serve
as indicators of the presence of all industrial pollutants identified in the pollutant source
assessment. These additional parameters may be modified (added or removed) in accordance
with any updated SWPPP pollutant source assessment.
III.STANDARD PROVISIONS – REPORTING
A. Annual Stormwater Report. The results of the Discharger’s Annual Comprehensive Facility
Compliance Evaluation shall be reported in the Annual Stormwater Report to the Regional Water
Board no later than July 30. The Discharger shall include in the Annual Stormwater Report the
following:
1. A compliance checklist that indicates whether the Discharger has complied with or addressed
all applicable requirements of the SWPPP;
2. An explanation for any non-compliance requirements within the reporting year, as indicated
in the compliance checklist;
LEHIGH SOUTHWEST CEMENT COMPANY Order No. R2-2019-0024
PERMANENTE PLANT NPDES No. CA0030210
Attachment S – Stormwater Provisions S-9
3. An identification, including page numbers and sections, of all revisions made to the SWPPP
within the reporting year; and
4. The date(s) of the annual evaluation.
IV. DEFINITIONS
B. Authorized Non-Stormwater Discharges – Non-stormwater discharges are authorized if they
meet the following conditions:
1. Fire-hydrant and fire prevention or response system flushing;
2. Potable water sources, including potable water related to the operation, maintenance, or
testing of potable water systems;
3. Drinking fountain water and atmospheric condensate, including refrigeration, air
conditioning, and compressor condensate;
4. Irrigation drainage and landscape watering, provided that all pesticides, herbicides, and
fertilizers have been applied in accordance with manufacturer’s labels;
5. Uncontaminated natural springs, groundwater, foundation drainage, footing drainage;
