1                         Introduction

This Dust Control Plan (Plan or DCP) for Southern California Edison’s (SCE) Eldorado-Lugo-Mohave Series Capacitor Project (Project) presents the activities to be conducted to support compliance with the Applicant-proposed measures (APM) and/or the mitigation measures (MM) listed in Table 1. Compliance with the APMs and MMs will reduce potential fugitive dust impacts resulting from construction of the Project. This Plan is independent of any fugitive dust control plan or permit that may be required by specific local air districts, cities, or counties.

 

This Plan provides fugitive dust control methods for construction activities and/or sources that emit fugitive dust. These sources and/or activities include unpaved and paved roads, disturbed surface areas, earth-moving activities, and the management of large material stockpiles.

 

This Plan is based on information in the Environmental Assessment for Southern California Edison Eldorado-Lugo-Mohave Series Capacitor Project document DOI-BLM-CA-2010-0010-EA dated April 2020 and the Eldorado-Lugo-Mohave Series Capacitor Project Final Mitigated Negative Declaration dated November 2019. In the event revisions are made to the Plan, based on final engineering or receipt of final environmental clearance documents, the revised Plan will be provided to the California Public Utilities Commission (CPUC) and the Bureau of Land Management (BLM).

 

Project areas in California are under the jurisdiction of the CPUC and BLM and must comply with requirements administered under the authority of the Mojave Desert Air Quality Management District (MDAQMD). Project areas in Nevada are under the jurisdiction of Clark County and BLM and must comply with requirements administered under the authority of Clark County’s Department of Environment and Sustainability, Division of Air Quality (DESDAQ). This is further discussed in the following sections.

 

1.1                   Project Description

This Project will increase capacity and power flow between SCE’s existing Eldorado, Lugo, and Mohave Substations to safely deliver renewable power to the Los Angeles Basin from the Eldorado and Mohave Substations. SCE’s Proposed Project would:

 

  • Construct 2 new 500-kilovolt (kV) mid-line series capacitors (i.e., the proposed Newberry Springs Series Capacitor and Ludlow Series Capacitor) and associated equipment.
  • Provide 2 communication paths between the series capacitor sites.
    • Install approximately 2 miles of overhead and 700 feet of underground telecommunications facilities as one path to connect the proposed series capacitors to SCE’s existing communication system.
    • Install approximately 2 miles of underground telecommunications facilities as a second communication path to connect the series capacitors to SCE’s existing communication system.
  • Provide station light and power to the proposed series capacitors by extending and/or rerouting existing lines to create approximately 2 miles of overhead and 700 feet of underground 12 kV distribution circuits. (The new distribution poles would support overhead telecommunication facilities as well as the electric distribution lines.)
  • Construct 3 new fiber optic repeater facilities (Barstow, Kelbaker, and Lanfair) within the Lugo- Mohave Right-of-Way (ROW).
  • Install distribution lines for light and power at the 3 proposed fiber optic repeater sites.
  • Install underground telecommunications facilities from existing transmission structures to the Barstow, Kelbaker, and Lanfair fiber optic repeater sites.
  • Address 16 potential overhead clearance discrepancies at 14 locations by:
    • Relocating, replacing, or modifying existing transmission, subtransmission, and distribution facilities at approximately 12 locations along the Eldorado-Lugo, Eldorado-Mohave, and Lugo-Mohave 500 kV transmission lines to address 14 of the overhead clearance discrepancies. Tower modifications would include raising 9 towers up to approximately 18.5 feet by inserting new lattice-steel sections in tower bodies.
    • Performing minor grading at 2 locations along the Lugo-Mohave 500 kV transmission line to address 2 of the overhead clearance discrepancies.
  • Install approximately 232 miles of optical ground wire (OPGW) (approximately 59 miles on the Eldorado-Mohave transmission line and approximately 173 miles on the Lugo-Mohave transmission line and approximately 3 miles of underground telecommunications facilities in the vicinity of the Mohave Substation).
  • Modify and strengthen the ground wire peak of existing suspension towers where OPGW splices would occur. (Some of these towers would also require minor modifications to the steel in the tower body.)
  • Install approximately 2,000 feet of underground telecommunications facilities within the existing Lugo, Mohave, and Eldorado substations.
  • Within Lugo Substation, perform modifications on the existing series capacitors and install new terminating equipment and remove 2 existing tubular steel poles (TSP) and install 2 new TSPs on the Eldorado-Lugo and Lugo-Mohave 500 kV transmission lines.
  • Within the Eldorado Substation, perform modifications on the existing series capacitors and upgrade the terminal equipment on the Eldorado-Lugo 500 kV transmission line.
  • Within the Mohave Substation, replace existing series capacitors on the Lugo-Mohave 500 kV transmission line and install new terminal equipment on the Eldorado-Mohave and Lugo- Mohave 500 kV transmission lines.
  • Install (if necessary) cathodic protection on approximately 60 miles of SoCalGas’s natural gas pipelines parallel to SCE’s Lugo-Mohave 500 kV transmission line and on other pipelines as needed.

 

 

1.2                        Project Location

The Project is located in southern California and southern Nevada, within the Mojave Basin and Range Ecoregion. It will extend northeast from Lugo Substation (located in San Bernardino County, California) to Eldorado Substation (located in the City of Boulder City, Nevada) and Mohave Substation (located in Clark County, Nevada), and from Mohave Substation northwest to Eldorado Substation. The Project is located on land under the jurisdiction of the BLM, the Mojave National Preserve (MNP) administered by the National Park Service (NPS), the Bureau of Reclamation, and the Department of Defense. Portions of the

 

Project will also cross the City of Hesperia in California, as well as the unincorporated communities of Searchlight and Laughlin in Nevada. The majority of the Project will be constructed within existing SCE easements, fee-owned properties, and public franchise areas. SCE will need a minimum of 1.9 acres of additional ROW from the BLM to construct the proposed Newberry Springs Series Capacitors and a minimum of 1.6 acres of additional private property to construct the proposed Ludlow Series Capacitor.

 

1.3                   Lead, Cooperating, and Consulting Agencies

1.3.1               Lead Agencies

 

Lead agencies have discretionary approval over the Project and are responsible for reviewing aspects of the measures documented in this Plan. The CPUC is California’s lead agency responsible for compliance with the California Environmental Quality Act (CEQA) for Project areas on non-federal lands. The CPUC issued an Initial Study/Mitigated Negative Declaration for the Project under CEQA. The BLM Desert District Office is the federal lead agency responsible for compliance with National Environmental Policy Act for the Project areas on federal lands.

 

1.3.2               Cooperating Agencies

 

Because the Project also crosses the MNP, the NPS elected to participate as a cooperating agency for the environmental review of the Project. Although the existing transmission lines associated with the Project also cross lands administered by the Bureau of Reclamation and the Department of Defense, the NPS represents the only federal cooperating agency at this time.

 

1.3.3               Consulting Agencies

 

Consulting agencies are public agencies, other than the lead agencies, that may provide guidance or information needed to satisfy the requirements of the measures contained in this Plan. Consulting agencies for select MMs listed in Table 1 include MDAQMD and DESDAQ. Project areas in California will be subject to plans and permits approved by MDAQMD while Project areas in Nevada will be subject to plans and permits approved by DESDAQ.

 

1.4                   Mitigation Measures

The APMs and MMs addressed in this Plan are provided in Table 1. This Plan is listed as a submittal requirement in the Project’s 2020 Environmental Assessment for Southern California Edison Eldorado- Lugo-Mohave Series Capacitor Project and 2019 Eldorado-Lugo-Mohave Series Capacitor Project Final Initial Study/Mitigated Negative Declaration.

Text of Measure

MM AQ- 1 (CPUC)

Prepare and Implement a Dust Control Plan

SCE shall minimize visible fugitive dust emissions by implementing the following dust control measures derived from MDAQMD Rule 403.2. Prior to commencing earth-moving activity, SCE shall prepare and submit to the MDAQMD, Clark County DAQ, CPUC, BLM and NPS a Dust Control Plan that describes all dust control measures that will be implemented for the project, including, but not limited to:

 

Table 1      Mitigation Measures

Measure

Text of Measure

  • Use periodic watering for short-term stabilization of disturbed surface area to minimize visible fugitive dust emissions. If used, non-water-based or chemical soil stabilizers and dust suppressants shall be non-toxic and must not cause loss of vegetation, adverse odors, or additional emissions of ozone precursor reactive organic gases (ROG) or volatile organic compounds (VOC).
  • Provide stabilized access route(s) to the project site as soon as is feasible and enforce a maximum 15 mile per hour vehicle speed limit on any unpaved surface.
  • Stabilize graded site surfaces upon completion of grading when subsequent development is delayed or expected to be delayed more than thirty days, except when such a delay is due to precipitation that dampens the disturbed surface sufficiently to eliminate visible fugitive dust emissions.
  • Maintain natural topography to the extent possible.
  • Construct parking lots and paved areas first, where feasible.
  • Take actions sufficient to prevent project-related trackout or spills onto publicly maintained paved surfaces, and cleanup project-related trackout or spills on publicly maintained paved surfaces within 24 hours.
  • Cover loaded haul vehicles or provide adequate freeboard while operating on publicly maintained paved surfaces.

Reduce non-essential earth-moving activity under high wind conditions, gusts exceeding 25 miles per hour.

MM AQ-1 (BLM)

A Dust Control Plan shall be prepared and implemented. Notwithstanding whether a violation of any air quality permit, law or regulation results, SCE will cooperate with the Authorized Officer in implementing and maintaining reasonable and appropriate dust control methods in conformance with law and appropriate to the circumstances at the

sole cost of the SCE. See LUPA-AIR-1/2/4/5.

MM AQ-2

(BLM)

During excavation, backfilling, and contouring, the disturbed soil shall be wetted sufficiently in order to effectively reduce airborne dust and reduce soil erosion. See LUPA-

AIR-1/2/4/5.

MM AQ-4 (BLM)

SCE shall not violate applicable air standards or related facility siting standards established by or pursuant to applicable federal, state, or local laws or regulations. SCE shall be responsible for dust abatement within the limits of the right-of-way and is responsible for obtaining all necessary permits from appropriate authorities for acceptable dust abatement and control methods (e.g., water, chemicals). SCE shall be solely responsible for all violations of any air quality permit, law or regulation, as a result of its action,

inaction, use or occupancy of the right-of-way. See LUPA-AIR-1/2/4/5.

MM AQ-5 (BLM)

Prior to relinquishment, abandonment, or termination of this right-of-way, SCE shall apply reasonable and appropriate dust abatement and control measures to all disturbed areas. The abatement and measures shall be designed to be effective over the long-term (e.g., rock mulch or other means) and acceptable to the Authorized Officer. See LUPA-AIR-

1/2/4/5.

MM AQ-6 (BLM)

During construction, fugitive dust would be controlled by implementing the following measures:

  • Surfaces disturbed by construction activities would be covered or treated with water until the completion of activities at each site of disturbance.
  • Inactive disturbed (e.g., excavated or graded areas) soil and soil piles would be sufficiently watered or sprayed with a soil stabilizer to create a surface crust or would

be covered.

 

Table 1      Mitigation Measures

Measure

Text of Measure

  • Drop heights from excavators and loaders would be minimized to a distance of no more than 5 feet. Vehicles hauling soil and other loose material would be covered with tarps or maintain at least 6 inches of freeboard.
  • Within California and Nevada, vehicle speeds on unpaved roads, unpaved traffic areas, and parking areas would be restricted to 15 miles per hour. Vehicle speeds on state and county roadways would adhere to all posted speed limits.

Within Nevada, unpaved non-public traffic and parking areas designated for utilization during Proposed Project construction would be effectively stabilized to control dust emissions (e.g., using water). In California, unpaved non-public traffic and parking areas designated for utilization during Proposed Project construction would be effectively

stabilized to control dust emissions with water.

LUPA-BIO-6 (BLM)

The application of water and/or other palliatives for dust abatement in construction areas and during project operations and maintenance will be done with the minimum amount of water necessary to meet safety and air quality standards and in a manner that prevents

the formation of puddles, which could attract wildlife and wildlife predators.

APM-AIR-01

Fugitive Dust. During construction, fugitive dust would be controlled by implementing the following measures:

  • Surfaces disturbed by construction activities would be covered or treated with a dust suppressant or water until the completion of activities at each site of disturbance.
  • Inactive disturbed (e.g., excavated or graded areas) soil and soil piles would be sufficiently watered or sprayed with a soil stabilizer to create a surface crust, or would be covered.
  • Drop heights from excavators and loaders would be minimized to a distance of no more than 5 feet. Vehicles hauling soil and other loose material would be covered with tarps or maintain at least 6 inches of freeboard.
  • Within Nevada, vehicle speeds on unpaved traffic and parking areas would be restricted to 15 miles per hour. In California, vehicle speeds on unpaved roadways would adhere to all posted speed limits.

Within Nevada, unpaved non-public traffic and parking areas designated for utilization during Proposed Project construction would be effectively stabilized to control dust emissions (e.g., using water or chemical stabilizer/suppressant). In California, unpaved non-public traffic and parking areas designated for utilization during Proposed Project construction would be effectively stabilized to control dust emissions with a chemical

stabilizer/suppressant.

1.5                   Applicable Activities and Project Areas

The activities addressed in this Plan are as follows:

 

l  Construction work, including ground-disturbing activities, and paved and unpaved road travel

 

This Plan is applicable to all Project areas within California and Nevada (Figure 1), including Federally administered lands. A separate dust control plan/permit from MDAQMD for Project activities within

 

California also exists. The dust control plan/permit from the MDAQMD will apply to all Project areas within California, including activities conducted on BLM land. Similarly, a separate dust mitigation plan/permit from DESDAQ for Project activities within Nevada, including activities conducted on BLM land also exists. As a result, the requirements within this Plan and the MDAQMD and DESDAQ plans/permits overlap. Individual APMs and MMs are applicable to specific segments as listed in Table 2. Additional measures may be required unique to MDAQMD and DESDAQ and specific air district approved dust control plans and permits should also be complied with by the Project team.

A standard practice for dust control includes the use of dust palliatives. Dust palliatives are commonly referred to by several names. For this plan, the following terms are used interchangeably:

 

l  Soil Stabilizer

l  Soil Binder

 

Dust Palliatives to be used on the project (except within the MNP) consist of the following types:

 

l  Water

l  Chemical Stabilizers, which include:

¡  Synthetic polymers- (e.g. FSB1000)

¡  Organic petroleum products: modified & unmodified Asphalt emulsions

¡  Deliquescent/ Hygroscopic salts

¡  Lignin-Based Types (Lignosulfonate)

l  Fibers/Mulches

l  Organic non- petroleum products

 

Dust palliatives proposed for use during this project are included in Appendix A. These dust palliatives are approved for use by the DESDAQ in Nevada and are pending MDAQMD approval. Dust palliatives will not be used on BLM or private land in California, until the MDAQMD issues approval for such use. Only water will be used as a dust palliative within the boundaries of the MNP.

 

2.1                   Fugitive Dust Control Measures for Project Implementation

This section contains fugitive dust control measures applicable to all Project areas, including federally administered lands and non-federal lands in California and Nevada, throughout the various stages of construction.

 

The following methods are required to achieve compliance with all CPUC and BLM dust control MMs and/or APMs. In implementing these measures, the Project will comply with all rules and regulations applicable to SCE’s standard policies and local Air District requirements. The MDAQMD and DESDAQ specific dust control regulations are summarized in Section 2.2 and the agency specific permits are included in Appendix B and C.

 

Figure 2         California Air Quality Management Districts

 

 

 

Figure 3         Mojave Desert Air Quality Management District

 

2.1.1               Travel on Unpaved Roads

 

The following fugitive dust control measures may be implemented for travel on unpaved roads and unpaved parking lots during construction:

 

  • Travel on unpaved roads will be limited to the extent possible, and traffic will be directed over established haul routes.
    • Unpaved road (access and spur) vehicle travel will not exceed the maximum posted speed limit. On roads without a posted speed limit, vehicles will be limited to 15 miles per hour.
    • Gravel will be placed on access road approaches, and track-out control devices such as rumble plates may be installed at the intersection of unpaved access roads and public paved roads.

 

2.1.2               Travel on Paved Roads

 

Prior to construction equipment travel on paved roads, the following may be implemented:

 

  • Fugitive dust will be minimized while transporting soil and other materials on paved roads by covering vehicles hauling soil and other loose material with tarps, in addition to maintaining freeboard in compliance with local Air District regulations. Clark County requires 3 – 6 inches of freeboard per the DESDAQ Construction Activity Handbook included by reference in CCAQR 94; while California requires a minimum of 6 inches of freeboard per California Vehicle Code 23114(e)(4)). Reference air district specific permits and plans for additional information and requirements.
    • Vehicle tires will be inspected prior to entering paved roadways from unpaved areas to verify they are free of dirt. To clean tires, the following may be implemented:
      • Gravel will be placed on access road approaches and track-out control devices such as shaker plates may be installed at the intersection of unpaved access roads and paved roads.
      • The construction team shall conduct a visual inspection of the vehicle wheels and the wheels of the equipment loaded upon each vehicle, to assess the presence of dirt. If caked dirt or mud is present, such shall be removed from wheels prior to entering paved intersections, to the extent feasible.
      • Track-out onto paved roads will be removed at the conclusion of the workday or evening shift with water sweepers (or as required by local District regulations) if visible soil material from the construction sites or unpaved access roads is carried onto adjacent public streets.

 

 

2.1.3               Active Disturbed Surface Areas

 

The following will be implemented, for areas disturbed by construction activities, to limit visible dust emissions from exiting the Project boundaries, in compliance with regulatory requirements:

 

  • Dust control during construction will be achieved primarily through the application of water. Dust palliatives are not intended. However, should they become necessary or preferred, dust palliatives will be non-toxic, and will not cause vegetation loss, adverse odors, or additional emissions of ozone precursor reactive organic gasses or volatile organic compounds. Dust palliatives proposed for use during this project are included in Appendix A. These dust palliatives are approved for use by the DESDAQ and are pending MDAQMD approval. The dust palliatives will not be used on BLM or private land in California until MDAQMD issues approval for use. Only water will be used as a dust palliative within the boundaries of the MNP.
  • All active construction areas, unpaved access roads, parking areas, and staging areas will be watered to control fugitive dust. Sites may be pre-watered up to 48 hours in advance of clearing; water will be applied prior to, during, or after earthmoving operations; and water will be applied as needed should visible emissions occur. The water trucks will be available during all work hours, and outside work hours if fugitive dust becomes an air quality compliance issue outside of work hours.
  • The majority of water application is intended in the construction areas of the new capacitor sites and their access roads. Fugitive dust emissions from existing unpaved roads and unpaved ROW easements will be controlled by limiting traffic speed; however, water application controls may be used if needed.
  • The use of water and/or dust palliatives for dust control will be minimized to the extent needed to comply with safety and air quality standards, in a manner that prevents the pooling of water that may attract wildlife and nearby predators.
  • Reduce non-essential earth-moving activity when wind gusts exceed 25 miles per hour.

 

2.1.4               Inactive Disturbed Surface Areas

 

Inactive disturbed areas are not intended during the project. Project areas will be active areas, or areas in which active work has been completed and not left inactive. Should inactive disturbed surface areas be generated during the project, the following dust mitigation would apply.

 

Inactive disturbed areas (project approved grading site surfaces) will be sufficiently watered or will be covered. Areas will be stabilized upon completion of grading when subsequent development is delayed or expected to be delayed more than 14 days (7 days in CA), except when such a delay is due to precipitation that dampens the disturbed surface sufficiently to eliminate visible fugitive dust emissions. Stabilization will include:

 

  • Restricting vehicular access
  • Applying and maintaining water on unvegetated areas
    • The use of water or dust palliatives for dust control will be minimized to the extent needed to comply with air quality standards in order to minimize or prevent pooling of water that may attract wildlife and nearby predators.

 

2.1.5               Open Storage Piles

 

Imported fill will be placed at the same time that it arrives to the site when feasible. However, when material is stockpiled during construction, stockpiles will be watered to control fugitive dust and covered if inactive.

 

2.1.6               Construction Transportation Plan

 

No specific mitigation is applicable.

 

2.1.7               Road Travel Plan

 

For construction of this project, SCE and its contractors will utilize a combination of through roads and spur roads accessed from existing paved and unpaved public and private roads located on public, private, and government lands. Access to the transmission line ROW for construction activities and future operation and maintenance activities associated with the project will also utilize these roads.

 

For construction sites with unpaved access greater than 1 mile, the following actions will be taken:

 

  • Travel of heavy equipment in and out of the unpaved areas will be limited by moving from construction site to construction site rather than back to marshalling or staging areas, to the extent feasible.
    • Construction workers may carpool and/or be bused to construction sites, as practicable, and in accordance with project approved Covid 19 policies.

 

2.1.8               Earth Moving Activities.

 

Some new temporary access roads, and some permanent access roads to the new capacitor sites will be constructed. Permanent disturbance will occur at the capacitor sites. Construction of the two new

 

capacitor sites will require earthwork totaling about 8.4 acres. The following will be implemented for earth-moving activities.

 

  • Earthwork activities such as clearing, grading, cutting, and back fill will be limited to designated areas, mostly at the new capacitor locations, and minimally where unpaved access roads will be constructed.
  • Earthwork will be minimized to the extent feasible while meeting project needs.
    • Earthwork being performed in temporary work areas will be minimized to maintain natural topography to the extent possible to assist in final restoration efforts.
    • Areas that will be cleared that have low soil moisture content will be pre-watered up to 48 hours in advance.
    • Water will be applied prior to, during, or after earthmoving operations as needed should visible emissions occur.

 

2.2                   Air District Specific Dust Control Rules

This Plan is applicable to all components of the Project, including Federally administered lands. The fugitive dust control rules promulgated by the air districts traversed by the Project, MDAQMD and DESDAQ, contain fugitive dust control requirements that will be implemented by the construction team.

 

2.2.1               Mohave Desert Air Quality Management District

 

 

Construction in all Project areas within California fall under the jurisdiction of MDAQMD. The construction team must comply with MDAQMD Rules 403 and 403.2. Project activities performed within the MDAQMD and applicable air district requirements are summarized in this section. The MDAQMD Dust Control Permit requirements for the project areas in California are provided in Attachment B.

 

 

The construction team will implement the following MDAQMD rules to ensure project compliance with MDAQMD Rule 403.2:

  • Use periodic watering for short-term stabilization of disturbed surface areas to minimize visible fugitive dust emissions.
  • Provide stabilized access route(s) to the project site as soon as is feasible and enforce a maximum 15 mile per hour vehicle speed limit on any unpaved surface.
  • Stabilize graded site surfaces upon completion of grading when subsequent development is delayed or expected to be delayed more than thirty days, except when such a delay is due to precipitation that dampens the disturbed surface sufficiently to eliminate visible fugitive dust emissions.
  • Maintain natural topography to the extent possible.
  • Construct parking lots and paved areas first, where feasible.
    • Take sufficient actions to prevent project-related trackout or spills onto publicly maintained paved surfaces, and cleanup project-related trackout or spills on publicly maintained paved surfaces within 24 hours.
    • Cover loaded haul vehicles or provide adequate freeboard while operating on publicly maintained paved surfaces.
    • Reduce non-essential earth-moving activity under high wind conditions, gusts exceeding 25 miles per hour.
    • Only remove the minimum amount of vegetation necessary for the construction of structures and facilities during construction.
    • SCE will install and maintain signage with project contact information that meets the minimum standards of the Rule 403.1 Implementation Handbook, prior to initiating any type of earth- moving activities.

 

2.2.2         Clark County Department of Air Quality

 

Construction in all Project areas located within Nevada fall under the jurisdiction of DESDAQ. The construction team will comply with the following Clark County Air Quality Regulations (CCAQR):

 

l  Section 41 – Prohibits the handling, transporting, or storage of any material in a manner that allows or may allow controllable particulate matter to become airborne.

l  Section 90 – Prohibits fugitive dust from Open Areas and Vacant Lots

l  Section 91 – Prohibits fugitive dust from Unpaved Roads, Unpaved Alleys, and Unpaved Easement Roads

l  Section 92 – Prohibits fugitive dust from Unpaved Parking Lots and Storage Areas

l  Section 93 – Prohibits fugitive dust from Paved Roads and Street Sweeping Equipment

l  Section 94 – Requires permitting and Dust Control for Construction Activities

 

Project activities performed within Clark County and applicable air district requirements are summarized in this section. These control measures are defined within the DAQ’s Dust Control Handbook. DAQ staff may inspect the project location at any time without prior notice to determine if compliance with the terms and conditions of the Dust Control Handbook are being met. The DESDAQ Dust Mitigation Control Permit requirements for the project areas in Nevada are provided in Attachment C and are summarized as follows:

  • Stabilize all project construction areas before, during, and after construction activities, including backfilling of material, trenching, clearing and grubbing, crushing material, grading
  • Stabilize all project surface soils where support equipment and vehicles will operate, including haul routes, parking areas, equipment staging areas
  • Limit visible emissions to no more than an average of 20% opacity for any period aggregating 3 minutes in any 60-minute period pursuant to Air Quality Regulations
  • Limit vehicle traffic and disturbance of soils where possible to limit visible dust opacity from vehicular operations
  • Pre-water construction areas prior to construction activities that disturb soils
  • Check belly-dump truck seals regularly and remove any trapped rocks to prevent spillage
  • Maintain 3-6 inches of freeboard to minimize spillage
  • Clean wheels and undercarriage of haul trucks prior to leaving construction site
    • Empty loader bucket slowly and keep loader bucket close to the truck to minimize the drop height while dumping
    • Use of soil to create a ramp for vehicle access over a curb is prohibited
      • Cease construction activities immediately when winds occur that cause fugitive dust emissions, despite adhering to all BMPs. Water trucks/pulls should continue to operate under these circumstances unless wind conditions are such that continued operation of watering equipment cannot reduce fugitive dust emissions or visibility is limited to an extent that it is hazardous to continue operating equipment.
      • Construction site superintendent(s), foreperson, or other designated onsite representative(s), as well as water truck driver(s) will attend and successfully complete the CCDAQ Dust Control Class.

 

2.3             Monitoring and Record Keeping Requirements

SCE will comply with all monitoring requirements and maintain all records specified in the DCP. SCE will also comply with the requirements of the MDAQMD and DESDAQ as set forth in the Project specific permits approved by the jurisdictional air districts.

  • The contractor will compile written daily records to document the specific actions taken to comply with this Plan and with MDAQMD Rule 403 and 403.2.
  • The contractor will compile written daily records to document the specific actions taken to comply with this Plan and with CCDAQ Section 41 and 94 Rules.
  • Soil conditions, including preventive and corrective measures, must be recorded every day the construction project is active.
  • Record use of suppressants and dust palliatives and retain records.
    • Trackout conditions, including preventive and corrective measures, must be recorded daily for every day that the construction project access is used by vehicles.
    • The contractor will monitor daily wind speeds to determine when sustained wind speeds are anticipated to exceed 25 mph. The contractor will record the dates and the actions taken to minimize fugitive dust emissions during high-wind events.

 

These records will be completed by the on-site environmental monitor and uploaded to FRED, SCE’s

record distribution database.

 

3                         Plan Approval

This Plan has been prepared to address the requirements of MM AQ-1 from the CPUC; MM AQ-1, MM AQ-2, MM AQ-4, MM AQ-5, and MM AQ-6 from the BLM; and APM-AIR-01. SCE requests review and approval of this Plan by the CPUC for non-federal lands in California. SCE requests review and approval of this Plan by the BLM for federal lands project wide. MDAQMD and DESDAQ are not requested for review of this Plan, and instead will review and approve the required air district specific plans and permits. In the event changes are made to this Plan, a revised plan will be provided to CPUC and BLM.

For traffic areas, water will be the primary method of dust control. Water will be applied as required by the air district permit. Additional water will be utilized as needed. It is not likely that a soil binder will be used to control dust on traffic areas. However, should the need arise, a soil binder will be applied to those areas per the manufacturer’s specifications. The preferred soil binder to be used and applied to traffic areas would also be synthetic polymers for continuity in product applications. The following is the preferred manufactured product at applications of this product type on traffic areas:

 

l  Soil Binder Product: FSB 1000

l  Application Rate: 175 gal/acre and per inch of stabilized road surface, plus 100 gal/acre topical. (i.e., one acre of stabilized road at 4” is 800 gal)

4A – PROJECT DESCRIPTION

 

Introduction

Southern California Edison (SCE) is proposing the Eldorado-Lugo-Mohave (ELM) Series Capacitor Project (Project) which would involve constructing two new mid-line series capacitors and make other improvements to increase capacity and power flow along three existing

500 kilovolt (kV) transmission lines in San Bernardino County, California and Clark County, Nevada. The subsections that follow describe the Project activities that would occur within Nevada.

 

Project Location

Figure 1: Project Overview Map shows the project vicinity and its components in Clark County. SCE’s existing Eldorado Substation is located near the intersection of United States (U.S.) Route 95 and Eldorado Valley Drive in the City of Boulder City. SCE’s existing Mohave Substation is located near the intersection of Thomas Edison Drive and Bruce Woodbury Drive in unincorporated Clark County. SCE’s existing McCullough Substation is located near the intersection of McCullough Pass and Route P in the City of Boulder City.

 

Project Activities

The Project includes the following main components within Nevada:

 

  • Correction of one overhead clearance discrepancy1 between Towers M4-T1 and M4-T2 along the Eldorado-Mohave 500 kV Transmission Line. To correct the discrepancy at this location, Tower M4-T1 will be raised by a minimum of approximately 18.5 feet and the tower’s foundation will be modified as required.

 

  • Installation of telecommunications facilities to connect the Proposed Project to SCE’s existing telecommunications system, including the following:

 

–        removal of an existing overhead ground wire, modification of existing towers to support optical ground wire (OPGW), and installation of approximately 70 miles of overhead OPGW on SCE’s existing Eldorado-Mohave and Lugo-Mohave 500 kV Transmission Lines;

 

–        installation of approximately 3 miles of underground fiber optic cable from Mohave Substation to existing Tower M173-T2 on the Lugo-Mohave 500 kV Transmission Line; and

 

 

 

1 SCE has defined “discrepancies” as potential clearance problems between an energized conductor and its surroundings, such as the structure, another energized conductor on the same structure, a different line, or the ground. SCE has identified one discrepancy along the Eldorado-Mohave 500 kV Transmission Line in Nevada where modification of a transmission structure is needed to address National Electrical Safety Code overhead clearance requirements.

–        installation of fiber optic cable within the existing Mohave and Eldorado Substations.

  • Modifications within the existing Mohave, Eldorado, and McCullough Substations including the following:

 

–        upgrade of the existing series capacitor banks at Eldorado Substation,

–        installation of new terminal equipment at Eldorado and Mohave Substations,

–        replacement of the existing series capacitor bank at Mohave Substation,

–        demolition and removal of an existing structure/shed at Mohave Substation, and

–        replacement of five existing 500 kV circuit breakers at McCullough Substation.

Construction Schedule

Construction is scheduled to begin in October 2020 and is expected to take approximately 21 months to complete.

 

Construction Contractors

The following contractors will be working on the Project: EPC Contractor- Beta Engineering

Grading and Below Grade Contractor- ACC Construction INC (ACC) Electrical Contractor- CA Energy Power (NRG)

Testing Contractor- Siemens UG Telecom Contractor- TBD

Substation Upgrade Contractor- SC&MDust Control Budget

The total dust control budget for the Project is approximately $180,000.

 

Disturbance Area

Because the project is located along an existing 500kV overhead transmission alignment, the OPGW construction process will begin at the north end of the alignment and will continue south along the alignment until the project is complete. The total area of non-linear project disturbance will be approximately 61.5 acres.

 

4B – SITE PLAN

 

A detailed site plan has been included in Attachment A: Detailed Site Plan. The Project will occur within one phase. The construction activities are described in Section 4A – Project Description. The laydown yards and existing substation sites may be used for temporary construction offices. Attachment A: Detailed Site Plan shows the access roads that will be used for the Project. All temporary work areas, indicated in the maps, may be treated with dust palliatives. As per the phone conversation with Heather MacKinnon from the Clark County Department of Air Quality (DAQ) on January 10, 2019, the determination of the Particulate

REVISED DRAFT                                                                                                                 Dust Mitigation Plan Supplement

 

 

Emission Potential (PEP) and accompanying soils analysis is no longer required for projects that are 50 acres or greater in size. Upon review of the DAQ’s Dust Control Handbook, all project activities located north of Tower 51-T2 on the Eldorado-Mojave 500 kV Transmission Line are assumed to be located in an area of High PEP. The remainder of the project is assumed to be in an area of Moderate Low PEP. A list of parcels crossed by the project has been included as Attachment B: Parcel List.

 

4C –EXPLANATION OF CONTROL MEASURES

 

The control measures that will be implemented during the Project will be in accordance with the DAQ’s Dust Control Handbook.

 

Wind Events

If wind speeds become excessive (15+ mph gusts) and typical control methods cannot provide adequate dust control, SCE will implement additional, reasonable efforts, such as applying additional water and/or water/surfactant mixture, covering materials, or shutting down operations if necessary. If operations are shut down as a control method, water and/or water/surfactant mixture application will continue, as required.

 

4D – CONTINGENCY PLAN

 

SCE will comply with all applicable rules and regulations regarding fugitive dust as a result of construction activities, including Sections 40, 41, 90, 92, and 94 as applicable to the Project as well as the Clark County DAQ’s Construction Activities Dust Control Handbook. The dust control monitor will observe construction activities for visible emissions crossing property lines. Since excessive fugitive dust emissions are easily detected visually, this will be the method for determining whether the dust control measures being employed are adequately controlling fugitive dust emissions. In the event that dust control measures are not adequately controlling fugitive dust emissions, the frequency of watering/use of dust palliatives will be increased to adequately suppress fugitive dust emissions associated with Project activities such that visible emissions do not cross property lines. The suppression of visible emissions by increased watering/application of chemical stabilizers would also inhibit the creation of nuisance conditions, as described in Section 40 of the Clark County DAQ rules and regulations.

 

4E – SOIL STABILIZATION MEASURES

 

As previously stated in Section 4C – Additional Explanation of Control Measures, unpaved non- public traffic and parking areas designated for utilization during Project construction would be effectively stabilized to control dust emissions.

 

For non-traffic areas, water will be used as the primary dust control measure. Water will be applied at a minimum of 4 times per day. Additional water will be utilized as needed. Should water not control the dust from the project, a soil binder will be applied to those areas that require additional dust control measures in accordance with the manufacturer’s specifications.

 

The preferred soil binder to be used and applied to non-traffic areas would be synthetic polymers. The following is the preferred manufactured product within this product type:

Dust Mitigation Plan Supplement                                                                                                                REVISED DRAFT

 

 

Soil Binder Brand:FSB 1000 Application Rate: 150 gal/acre Frequency: One time

Final Stabilization: Shall be determined by the SWPPP

Other possible soil binder product types for non-traffic areas may include organic non- petroleum-based products or may be standard fibers/mulches.

 

  • The application procedures of soil binders on non-traffic areas would be as follows:
  • When feasible, begin implementation of final stabilization BMPs when the area is no longer required for construction; otherwise implement temporary stabilization practices.
  • The Contractor shall be responsible for onsite revegetation of temporary disturbance areas as required by the environmental documents and permits. Prior to implementation of the final stabilization BMPs, the Contractor’s Qualified SWPPP Developer (QSD) shall coordinate with the Contractor’s restoration biologists and the SCE QSD to identify if the area will be stabilized through revegetation or through the use of stabilization BMPs without vegetation to achieve final stabilization to satisfy the Notice of Termination (NOT) requirement of the General Permit.
  • Following construction activities, the Contractor’s biologist will evaluate whether reseeding is recommended, as well as recommend seed mix, seeding rate, and application methods, in consultation with SCE and the applicable agencies.
  • For non-vegetative stabilization methods, RUSLE2 shall be used to ensure that post- construction sediment loss does not exceed preconstruction sediment loss. Where vegetative stabilization is required, the contractor shall evaluate additional stabilization BMPs to be used to determine if the area can be removed from permit coverage using the RUSLE2 method. Typical stabilization BMPs and conditions are presented below; RUSLE2 verification should be performed prior to implementation of BMPs and is required for a NOT.
  • Temporary BMPs (except perimeter controls), construction material, and wastes shall be removed prior to implementation of final stabilization BMPs.

 

Minimum post-construction BMPS for all temporary disturbance areas:

  • Track walk, sheepsfoot roll, or otherwise roughen disturbed areas with care to preserve any remaining vegetation.
  • Apply wood fiber hydraulic mulch at 2500 pounds per acre. (this will likely be Earthguard Fiber Matrix)

 

For traffic areas, water will be the primary method of dust control. Water will be applied at a minimum of 4 times per day. Additional water will be utilized as needed. It is not likely that a soil binder will be used to control dust on traffic areas. However, should the need arise, a soil binder will be applied to those areas per the manufacturer’s specifications.

 

The preferred soil binder to be used and applied to traffic areas would also be synthetic polymers for continuity in product applications. The following is the preferred manufactured product at applications of this product type on traffic areas:

Soil Binder Product: FSB 1000

 

 

April 2020                                                                                                                                            Southern California Edison

4                                                                                                                      Eldorado-Lugo-Mohave Series Capacitor Project

 

REVISED DRAFT                                                                                                                 Dust Mitigation Plan Supplement

 

 

Application Rate: 175 gal/acre and per inch of stabilized road surface, plus 100 gal/acre topical. (i.e. one acre of stabilized road at 4” is 800 gal)

Frequency: One time

Final Stabilization: Shall be determined by the SWPPP

Other possible soil binder product types to use on traffic areas may include organic non- petroleum-based products or magnesium chlorides.

 

The application procedures of soil binders on traffic areas would be as follows:

  • When feasible, begin implementation of final stabilization BMPs when the area is no longer required for construction; otherwise implement temporary stabilization practices.
  • Compact disturbed soils as required by engineering specification and document compaction test for inclusion with a NOT.
  • Provide documentation of stabilization, including photos, to SCE QSD for verification that criteria have been met for removal from General Permit coverage.
  • Remove temporary BMPs and demobilize from the area.

 

4F – EMPLOYEE DUST CONTROL TRAINING AND COMPLIANCE.

 

As required by the DAQ’s Construction Activities Dust Control Handbook, the construction site superintendent(s), foremen, water truck/pull driver(s), and other designated on-site representative(s) will attend and successfully complete a Clark County Department of Air Quality and Environmental Management Dust Control Class or possess a current Dust Control Card. The Dust Control Monitor, along with on-site environmental inspectors, will ensure the Project remains in compliance with this plan.

Hi Heather,

Here is the revised app (page 2), map, and acreage calcs.

 

I’ve also provided a couple responses to your comments below.

 

I hope this covers everything we’ve discussed and we can move this permit along (fingers crossed). Thanks,

Dane,

I spoke to my supervisor and she is on the same page as me. I will need to call you later this afternoon. I have a meeting and will not be back in office until 12:30.

Start deleting any pages that do not have any soil disturbance like pages 2, 4, 5, 6,12,14, 16, 17, 19, 20, 24, 25, 27, 28, 29, 33, 34, 35, 38, 40, 42, 43, 44-51, 54, 56, 58, all of these don’t any areas that need to be permitted.

OK

We want grayscale and color ONLY areas that need to be permitted, and put acreage on each of these areas.

OK. Though the property lines also are colored red.

Helicopter landing zones do not need to be permitted or even on any map.

OK. These areas have been removed from the maps I need ONE APN per page, please make it much bigger.

Due to the automatic map development from GIS, this would need to be done manually. We hope that the additional APNs helps to locate the work areas.

Pg 7, looks like a lot going on, use one color for the blue and green areas with acreage. If it is a trench, please put the length x width on each page. This has been added Is the blue area the trench? Yes.

Why would you be trenching along the paved area (pg 9)? At lattice tower M173-T2 (on page 7), the optical groundwire goes from overhead to underground. A 3-mile trench is to be installed for the underground section of the fiber optic cable from this tower to the existing Mohave Substation.

“walking travel paths” delete. OK

Pg 10, if this yellow area is not part of the disturbance, delete. We don’t care about substation boundaries, or where the substation is.

The work area boundary at the substations were retained (we would like for this to remain to maintain consistency with our approved project work areas here), but is grayed out to show that it is not included in the area calc.

Pg 11, if the construction material yard is on dirt, that must be permitted. If it is on pavement, it does not unless you are storing soils on it.

The 3 yards that have been included in the map are on gravel and have been identified.

 

 

See how that goes.

 

 

Regards,

 

 

Heather Mackinnon

Hello Heather,

I’ve attached the updated page 2 of the application.

 

We’ve also revised the detailed map. Here is the link to access the map:

https://betaengineering.sharefile.com/d-s07af16371754ad5b

 

As discussed, we removed the work areas within the SCE transmission right-of-way that we do not intend to grade. Any portion of these work areas that extend outside of the right-of-way have been included in our area calcs.

The resulting breakdown of areas is as follows:

Non-Linear Workspace Type

Outside ROW

(acres)

Ground Disturbance at Existing (Eldorado & Mohave) Substations,

including: Structure Demolition, non-linear UG telecom, & Grading

11.16

Hello,

On the application you sent me, you have not done page 2 correctly. If you are using the application with Internet Explorer it will not let you enter anything more than a 10th of an acre. And, you do not currently have 3.6 NONLINEAR acres according to your reply below, you have approximately 47.9 NONLINEAR acres, and your LINEAR is not carried over to the right side, telling me you are not using the application correctly.

You are now stating you have 47.9 NONLINEAR, plus the 14.5 LINEAR, please redo page 2 correctly. See below in all BOLDED CAPS for replies.

Hello Heather,

I’ve been working on addressing each of your comments. The comments were straight forward, but required some additional work to break down the numbers as you’ve requested.

 

As you’ve indicated, the primary activity for the transmission work locations is to replace an existing overhead groundwire (OHGW) with optical groundwire (OPGW), which doesn’t directly

 

require ground disturbance. However, within each of the transmission work areas, vegetation will need to be cleared and minor construction grading may need be performed to prepare flat, level pull-sites to setup the wire pulling equipment. We believe that this site preparation may result in minor dirt disturbance for the overhead work areas, so it has been included in the dirt disturbance calculations and maps in the non-linear sections.

IF YOU ARE CHANGING THE GRADE OF THE AREA, IT WILL NEED TO BE INCLUDED, IF NOT DELETE THE MAPS WITH JUST THE POLE.

 

If this construction activity does not need to be considered because it does not involve design grading or design digging, then these overhead work areas can be removed from our dirt disturbance calcs and the overall acreage can be reduced.

 

Please see my complete responses to your questions below. Let me know if you have any other questions.

Thank you,

Hello,

I did not need another signed application.

We had provided the revised application so the official copy had a cell # included. We have provided revised application once again with the additional information requested below.

 

Just to clarify, is this line running from Laughlin Nv, to Boulder City Nv? The oversite map is not clear on that. You’re right about the overview map. It does not show the city in which the lines start and end.

There are 2 transmission lines, but the primary transmission line in NV does run from Laughlin to Boulder City.

The Eldorado-Mohave transmission line runs from Laughlin, NV to Boulder City, NV. The entire 60 miles of this line are in Clark County.

The other line is the Lugo-Mohave transmission line that runs from Laughlin, NV to Hesperia, CA. Approximately 15 miles (of 175) of this line are in Clark County.

 

On page 2 for the project location, the address entered does not exist. Please change page 2 in street field to starting point: street and city to ending point and you must list 2 major cross streets for your beginning point.

I’ve added the cross streets and city names for the start and end locations to the “Project Physical Location” section for the primary transmission line, the Eldorado-Mohave line.

 

Put an APN at the above location on page 2.

I’ve added the start and end APN’s to the “Project Physical Location” section. ON PAGE 2, YOU MUST ENTER ONE, SO ENTER THE STARTING APN. WE DO NOT NEED A BUNCH OF APNS.

 

On the maps show an APN on each page to easily identify each pages work area. ONLY ONE ON EACH MAP SO I CAN FIND THE AREAS.

The detailed map provided includes the APNs on each page.

 

It appears that a lot of the maps are only replacing the transmission line with no digging correct? If so, just submit the maps that show dirt disturbance, see following.

All work areas have a potential for dirt disturbance, so they are retained in the maps. These can be removed if you disagree with this assertion. AS STATED ABOVE, IF YOU ARE CHANGING THE GRADE, THEN INCLUDE IT, OTHERWISE NO.

 

Provide each work areas acreage including all areas where dirt disturbance will occur but not limited to below.

Trench length/width for the aprox. 3 miles of underground fiber optic (please be aware that the width must include trench width, spoils piles, equipment digging trench and any support vehicle disturbance alongside of trench). Please put this in the LINEAR section on page 2.

I’ve updated the Linear section of page 2 to include the UG telecom work area on Bruce Woodbury Drive, which was previously included with the non-linear work areas. This work area increased slightly due to rounding up the width to 40FT in the linear section of the permit.

 

All other will be put in the NONLINEAR section for these areas below where there will be dirt disturbance including parking, staging, trailers etc., again, you must justify how you came to

61.5 acres.

Structure demolitions & Grading work area (demolition will happen within the larger graded area)                          0.80 acres

Helicopter landing zone                                                                                                                                                                 10.69 acres DO NOT NEED IF YOU ARE NOT GRADING

PADS FOR LANDING ??

Telecommunication work areas (Non-linear telecom work areas completed at the existing substations)                   2.47 acres

Wire set up                                                                                                                                                                                        12.77 acres

Tower work                                                                                                                                                                                       2.57 acres

Man holes (a total of 14, 30FTx30FT manholes w/ aprons)                                                                                                                                  0.29 acres (this acreage is included with the respective linear and non-linear telecom work areas)

Newly disturbed travel paths (foot paths to walk the initial pull line from the tower to the pull site)                          0.78 acres Staging, parking, equipment storage areas                                                                                                                                                                                                                                                                                                              17.50 acres

TOTAL (for non-linear sections)                 47.58 acres     47.87 = 47.9

Hi Heather,

There was a map that is included with the application, but it is rather large. I had asked for a means to provide the map outside of email.

 

I tried to send the map via email a moment ago, but I received an “undeliverable” message for your email.

I called the DAQ office to see if there were another means to provide the large file. We agreed that providing a sharefile link would be the next best submittal option.

 

Please use the following link to access that map that was to be included with the SMP as Attachment A: https://betaengineering.sharefile.com/d-sc21ae0061984f70a

 

We will also be providing the revised signed copies of the application (with phone #) and SMP (with BMP’s removed) shortly. Please let me know that this email has been received.

CAUTION EXTERNAL EMAIL

Greetings,

Please reply to this email only as soon as possible so not to delay the approval process. I have reviewed your Dust Control Operating Permit application and have questions and/or need additional information. Applications cannot be updated with verbal authorization so please reply to this email. If you have questions, feel free to email me those inquiries.

 

Please supply Joy Brooks required cell phone number.

 

Please remove all the DAQ BMP’s from your SMP. These are required and already included once the permit is issued.

 

A breakdown/justification of the total acreage of 61.5 acres must be submitted to show how the project acreage was calculated.

 

The map needs to clearly show areas to be permitted. Acreage must be identified for all project areas, stockpile locations & staging areas. Dimensions may not be required (unless the portion is LINEAR in which case the length and width of the disturbance must be given).
