Preamble

Title V of the Clean Air Act Amendments of 1990 (the Act) required EPA to create an operating permit program for implementation by state or local air permitting authorities. The purposes of this program are: (1) to require an affected company to assume full responsibility for demonstrating compliance with applicable regulations; (2) to capture all of the regulatory information pertaining to an affected company in a single document; and (3) to make permits more consistent with each other.

A company is subject to the Title V program if it meets any of several criteria related to the nature or amount of its emissions. The Title V operating permit specifies what the affected company is, how it may operate, what its applicable regulations are, how it will demonstrate compliance, and what is required if compliance is not achieved. In Jefferson County, Kentucky, the Louisville Metro Air Pollution Control District (LMAPCD or APCD) is responsible for issuing Title V permits to affected companies and enforcing local regulations and delegated federal and state regulations. EPA may enforce federal regulations but not “District Only Enforceable Regulations.”

Title V offers the public an opportunity to review and comment on a company’s draft permit. It is intended to help the public understand the company’s compliance responsibility under the Clean Air Act. Additionally, the Title V process provides a mechanism to incorporate new applicable requirements. Such requirements are available to the public for review and comment before they are adopted.

Title V Permit General Conditions define requirements that are generally applicable to all Title V companies under the jurisdiction of LMAPCD. This avoids repeating these requirements in every section of the company’s Title V permit. Company-specific conditions augment the General Conditions as necessary; these appear in the sections of the permit addressing individual emission units or emission points.

The General Conditions include references to regulatory requirements that may not currently apply to the company, but which provide guidance for potential changes at the company or in the regulations during the life of the permit. Such requirements may become applicable if the company makes certain modifications or a new applicable requirement is adopted.

When the applicability of a section or subpart of a regulation is unclear, a clarifying citation will be made in the company’s Title V permit at the emission unit/point level. Comments may also be added at the emission unit/point level to give further clarification or explanation.

The owner or operator’s Title V permit may include a current table of “insignificant activities.”

Insignificant activities are defined in District Regulation 2.16 section 1.23, as of the date the permit was proposed for review by U.S. EPA, Region 4.

Insignificant activities identified in District Regulation 1.02, section 1.38, and Appendix A may be subject to size or production rate disclosure requirements pursuant to Regulation 2.16 section 3.5.4.1.4.

Insignificant activities identified in District Regulation 1.02, section 1.38, and Appendix A shall comply with generally applicable requirements as required by Regulation 2.16 section 4.1.9.4.

General Conditions

Compliance– The owner or operator shall comply with all applicable requirements and with all terms and conditions of this permit. Any noncompliance shall constitute a violation of the Act, State, and District regulations and shall cause the source to be subject to enforcement actions including, but not limited to, the termination, revocation and reissuance, or revision of this permit, or denial of a permit application to renew this permit. Notwithstanding any other provision in the Jefferson County portion of the Kentucky SIP approved by EPA, any credible evidence may be used for the purpose of establishing whether the owner or operator is in compliance with, has violated, or is in violation of any such plan. (Regulation 2.16, sections 4.1.3, 4.1.13.1, and 4.1.13.7)
Compliance Certification– The owner or operator shall certify, annually, or more frequently if required in applicable regulations, compliance with the terms and conditions contained in this permit, including emission limitations, standards, or work practices. This certification shall meet the requirements of Regulation 2.16, sections 3.5.11 and 4.3.5. The owner or operator shall submit the annual compliance certification (Form 9400-O) directly to the EPA and to the District, as set forth in Regulation 2.16, section 4.3.5.4, at the following addresses:

US EPA – Region IV Air Pollution Control District

Air Enforcement Branch Room 205

Atlanta Federal Center 850 Barret Ave

61 Forsyth Street Louisville, KY 40204-1745

Atlanta, GA 30303-8960

This certification must be postmarked by 15 April of the year following the year for which the certification is being submitted, or other such due date as required by another applicable regulation.

Compliance Schedule– The owner or operator shall submit a schedule of compliance for each emission unit that is not in compliance with all applicable requirements. A compliance schedule must meet the requirements of Regulation 2.16, section 3.5.9.5. A schedule of compliance shall be supplemental to, and shall not condone noncompliance with, the applicable requirements on which it is based. For each schedule of compliance, the owner or operator shall submit certified progress reports at least semi-annually, or at a more frequent period if specified in an applicable requirement or by the District in accordance with Regulation 2.16 section 4.3.4. The progress reports shall contain:
1. Dates for achieving the activities, milestones, or compliance required in the schedule of compliance, and dates when activities, milestones, or compliance were achieved.
2. An explanation of why dates in the schedule of compliance were not or will not be met, and preventive or corrective measures adopted.
Duty to Supplement or Correct Application– If the owner or operator fails to submit relevant facts or has submitted incorrect information in the permit application, they shall,

upon discovery of the occurrence, promptly submit the supplementary facts or corrected information in accordance with Regulation 2.16, section 3.4.

5. Emergency Provision
1. An emergency shall constitute an affirmative defense to an enforcement action brought for noncompliance with technology-based emission limitations if the conditions in Regulation 2.16 are met. The affirmative defense of emergency shall be demonstrated through properly signed, contemporaneous operating logs, or other relevant evidence that:
  1. An emergency occurred and that the owner or operator can identify the cause of the emergency;
  2. The permitted facility was at the time being properly operated;
    1. During the period of the emergency the owner or operator expeditiously took all reasonable steps, consistent with safe operating practices, to minimize levels of emissions that exceeded the emission standards or other requirements in this permit; and
    2. The owner or operator submitted notice meeting the requirements of Regulation 1.07 of the time when emissions limitations were exceeded because of the emergency. This notice must fulfill the requirement of this condition, and must contain a description of the emergency, any steps taken to mitigate emissions, and any corrective actions taken.
  3. In an enforcement proceeding, the owner or operator seeking to establish the occurrence of an emergency has the burden of proof.
  4. This condition is in addition to any emergency or upset provision contained in an applicable requirement. (Regulation 2.16, sections 4.7.1 through 4.7.4)
Emission Fees Payment Requirements– The owner or operator shall pay annual emission fees in accordance with Regulation 2.08, section 1.3. Failure to pay the emissions fees when due shall constitute a violation of District Regulations. Such failure is subject to penalties and an increase in the fee of an additional 5% per month up to a maximum of 25% of the original amount due. In addition, failure to pay emissions fees within 60 days of the due date shall automatically suspend this permit to operate until the fee is paid or a schedule for payment acceptable to the District has been established. (Regulation 2.08, section 1.6)
Emission Offset Requirements– The owner or operator shall comply with the requirements of Regulation 2.04.
Enforceability Requirements– Except for the conditions that are specifically designated as ADistrict-Only Enforceable Conditions@, all terms and conditions of this permit, including any provisions designed to limit a source’s potential to emit, are enforceable by EPA and citizens as specified under the Act. (Regulation 2.16, sections 4.2.1 and 4.2.2)
9. Enforcement Action Defense
1. It shall not be a defense for the owner or operator in an enforcement action that it would have been necessary for the owner or operator to halt or reduce the

permitted activity in order to maintain compliance with the conditions of this permit.

The owner or operator’s failure to halt or reduce activity may be a mitigating factor in assessing penalties for noncompliance if the health, safety or environmental impacts of halting or reducing operations would be more serious than the impacts of continued operation. (Regulation 2.16, sections 4.1.13.2 and 4.1.13.3)
Hazardous Air Pollutants and Sources Categories– The owner or operator shall comply with the applicable requirements of Regulations 5.02 and 5.14.
Information Requests– The owner or operator shall furnish to the District, within a reasonable time, information requested in writing by the District, to determine whether cause exists for revising, revoking and reissuing, or terminating this permit, or to determine compliance with this permit. The owner or operator shall also furnish, upon request, copies of records required to be kept by this permit. (Regulation 2.16, section 4.1.13.6)

If information is submitted to the District under a claim of confidentiality, the source shall submit a copy of the confidential information directly to EPA at the address shown in General Condition 35.b. (Regulation 2.07, section 10.2)

Insignificant Activities– The owner or operator shall:
1. Notify the District in a timely manner of any proposed change to an insignificant activity that would require a permit revision. (Regulation 2.16, section 5)
2. Submit a current list of insignificant activities by April 15 of each year with the annual compliance certification, including an identification of the additions and removals of insignificant activities that occurred during the preceding year. (Regulation 2.16, section 4.3.5.3.6)
Inspection and Entry– Upon presentation of credentials and other documents as required by law, the owner or operator shall allow the District or an authorized representative to perform the following during reasonable hours: (Regulation 2.16, section 4.3.2)
1. Enter the premises to inspect any emissions-related activity or records required in this permit.
2. Have access to and copy records required by this permit.
3. Inspect facilities, equipment (including monitoring and air pollution control equipment), practices, or operations regulated or required by this permit.
4. Sample or monitor substances or parameters to assure compliance with this permit or any applicable requirements.
Monitoring and Related Record Keeping and Reporting Requirement– The owner or operator shall comply with the requirements of Regulation 2.16, section 4.1.9. Unless specified elsewhere in this permit, the owner or operator shall complete required monthly record keeping within 30 days following the end of each calendar month. The owner or operator shall submit all required monitoring reports at least once every six months,

unless more frequent reporting is required by an applicable requirement. The reporting period shall be 1 January through 30 June and 1 July through 31 December of each calendar year. All reports shall be sent to the District at the address shown in paragraph 2 of these General Conditions and must be postmarked by the 60^th day following the end of each reporting period, unless specified elsewhere in this permit. If surrogate operating parameters are monitored and recorded in lieu of emission monitoring, then an exceedance of multiple parameters may be deemed a single violation by the District for enforcement purposes. All reports shall include the company name, plant ID number, and the beginning and ending date of the reporting period. The compliance reports shall clearly identify any deviation from a permit requirement or a declaration that there were no such deviations. All semi-annual compliance reports shall include the statement “Based on information and belief formed after reasonable inquiry, I certify that the statements and information in this document are true, accurate, and complete” and the signature and title of a responsible official of the company.

The semi-annual compliance reports are due on or before the following dates of each calendar year:

Reporting Period Report Due Date

January 1 – June 30 August 29

July 1 – December 31 March 1 of the following year

If a change in the responsible official (RO) occurs during the term of this permit, or if an RO is added, the owner or operator shall provide written notification (Form AP-100A) to the District within 30 calendar days of such change or addition.

Off-permit Documents– Any applicable requirements, including emission limitations, control technology requirements, or work practice standards, contained in an off-permit document cannot be changed without undergoing the permit revision procedures in Regulation 2.16, section 5. (Regulation 2.16, section 4.1.5)
Operational Flexibility– The owner or operator may make changes without permit revision in accordance with Regulation 2.16, section 5.8.
Permit Amendments (Administrative)– This permit can be administratively amended by the District in accordance with Regulation 2.16, section 5.4.
Permit Application Submittal– The owner or operator shall submit a timely and complete application for permit renewal or significant revision. If the owner or operator submits a timely and complete application then the owner or operator’s failure to have a permit is not a violation until the District takes formal action on this permit application. This protection shall cease to apply if, subsequent to completeness determination, the owner or operator fails to submit, by the deadline specified in writing by the District, additional information required to process the application as required by Regulation 2.16, sections 3 and 5.2.

U4 Comments

The emission standards, monitoring, record keeping, and reporting requirements only apply to the boiler E1 (not the coal bunker E2) unless indicated.

LG&E’s proposal for removing COMS for Unit 3 and 4 at Mill Creek station was accepted in a letter from EPA dated Feb. 28, 2007. The District accordingly approved LG&E’s request for removing COMS for Unit 4, 5, and 6 for Cane Run providing PM CEMS are appropriately installed for these units.

The SO₂ and PM emissions can exceed the standards uncontrolled. The owner or operator is required to operate the control devices to meet the applicable limits for SO₂ and PM.

For the coal silos (E2), the owner or operator has shown, by worst-case calculations without allowance for a control device, that the hourly uncontrolled PM emission standard cannot be exceeded; therefore, no monitoring, recordkeeping, or reporting is required to demonstrate compliance with the applicable PM standards.

LG&E Cane Run submitted their TAC Environmental Acceptability Demonstration to the District on December 28, 2006, March 25, 2008, April 9, 2010, April 2, 2012, and May 13, 2014. Compliance with the STAR EA Goals was demonstrated in the source’s EA Demonstrations. SCREEN3 air dispersion modeling was performed for each emission unit that has non-de minimis TAC emissions. The following table demonstrates that the carcinogen risk and non-carcinogen risk values, calculated using the District approved PTE for each unit and the SCREEN model results from the source’s EA Demonstration, comply with the STAR EA goals required in Regulation 5.21 controlled.

The coal-fired boilers are subject to 40 CFR Part 64 – Compliance Assurance Monitoring (CAM) for Major Stationary Source since SO2, PM, and NOx emissions from each of the boilers may be greater than the major source threshold and control devices are required to achieve compliance with standards. On 8/18/2014, LG&E submitted a revised CAM Plan in which SO2 and NOx CEMS are used for compliance demonstration. PM CEMS is used to demonstrate compliance or provide an indication of continuous PM control.
1. The compliance reports are due on or before the following dates of each calendar year: Reporting Period Report Due Date

January 1^st through March 31^th May 30^th April 1^st through June 30^th August 29^th

July 1^st through September 30^th November 29^th October 1^st through December 31^st March 1^st

Boiler (E1) has TAC emission standards since its EA Demonstration was based on controlled PTE. If the controlled PTE for the TAC is less than de minimis level, De Minimis is listed as limit. If the controlled PTE for the TAC is greater than de minimis level, modeling results were used to calculate risk value to compare to the EA Goals. In this case, control PTE is used as limit. TAC emissions for the coal silos (E2) are de minimis according to Regulation 5.21, section 2.1.

This unit is equipped with CEMS for NOx, SO2, and PM. According to the District’s letter dated November 1, 2005, parametric monitoring of the ESP, FGD, and PJFF injection for this unit is removed as such monitoring would no longer be required for demonstration of compliance.

According to 40 CFR 63.9984(b), the compliance date for an existing EGU is April 16, 2015. The District approved LG&E’s request for the extension of the compliance date per

(40 CFR 63.6(i)(4)(i)). The compliance date for the EGUs at this plant is November 1, 2015.

LG&E submitted a CAIR permit application on April 29, 2014 and submitted a revised application on May 30, 2014 for coal-fired boiler U4, U5, U6 and NGCC unit U15. In June, 2014, the U.S. Supreme Court filed a motion with the U.S. Court of Appeals for the

D.C. Circuit to lift the stay of the Cross State Air Pollution Rule. While the Court considers the motion, CAIR remains in place and no immediate action from States or affected sources is expected.

The existing emission unit U4, U5, U6, U7, U8, U10, IA1 (previous U9), two parts washers of IA2 (previous U12), and U14 shall be shut down within the contemporaneous period of the NGCC unit construction project in order to have their emission decreases to be eligible for PSD/NSR netting analysis. According to 40 CFR 52.21(b)(3)(ii), the contemporaneous period is defined as “between the date five years before construction on the particular change commences and the date that the increase from the particular change occurs”. In this permit the term “operational” means “normal operations” as defined in 40 CFR 52.21.

U5 Comments

The emission standards, monitoring, record keeping, and reporting requirements only apply to the boiler E3 (not the coal bunker E4) unless indicated.

LG&E’s proposal for removing COMS for Unit 3 and 4 at Mill Creek station was accepted in a letter from EPA dated Feb. 28, 2007. The District accordingly approved LG&E’s request for removing COMS for Unit 4, 5, and 6 for Cane Run providing PM CEMS are appropriately installed for these units.

The SO₂ and PM emissions cannot meet the standards uncontrolled. The owner or operator is required to operate the control devices to meet the applicable limits for SO₂ and PM.

For the coal silos (E4), the owner or operator has shown, by worst-case calculations without allowance for a control device, that the hourly uncontrolled PM emission standard cannot be exceeded; therefore, no additional monitoring, recordkeeping, or reporting is required to demonstrate compliance with the applicable PM standards.

LG&E Mill Creek submitted their TAC Environmental Acceptability Demonstration to the District on December 28, 2006, March 25, 2008, April 9, 2010, April 2, 2012, and May 13, 2014. Compliance with the STAR EA Goals was demonstrated in the source’s EA Demonstrations. SCREEN3 air dispersion modeling was performed for each emission unit that has non-de minimis TAC emissions. The table under U4 Comment 5 demonstrates that the carcinogen risk and non-carcinogen risk values, calculated using the District approved PTE for each unit and the SCREEN model results from the source’s EA Demonstration, comply with the STAR EA goals required in Regulation 5.21 controlled.

The coal-fired boilers are subject to 40 CFR Part 64 – Compliance Assurance Monitoring (CAM) for Major Stationary Source since SO2, PM, and NOx emissions from each of the boilers may be greater than the major source threshold and control devices are required to achieve compliance with standards. On 8/18/2014, LG&E submitted a revised CAM Plan in which SO2 and NOx CEMS are used for compliance demonstration. PM CEMS is used to demonstrate compliance or provide an indication of continuous PM control.
1. The compliance reports are due on or before the following dates of each calendar year: Reporting Period Report Due Date

January 1^st through March 31^th May 30^th April 1^st through June 30^th August 29^th

July 1^st through September 30^th November 29^th

October 1^st through December 31^st March 1^st

Boiler (E3) has TAC emission standards since its EA Demonstration was based on controlled PTE. If the controlled PTE for the TAC is less than de minimis level, use De Minimis as limit. If the controlled PTE for the TAC is greater than de minimis level, modeling results were used to calculate risk value to compare to the EA Goals. In this case, control PTE is used as limit. TAC emissions for the coal bunker (E2) are de minimis according to Regulation 5.21, section 2.1.

This unit is equipped with CEMS for NOx, SO2, and PM. According to the District’s letter dated November 1, 2005, parametric monitoring of the ESP, FGD, and PJFF injection for this unit is removed as such monitoring would no longer be required for demonstration of compliance.

According to 40 CFR 63.9984(b), the compliance date for an existing EGU is April 16, 2015. The District approved LG&E’s request for the extension of the compliance date per (40 CFR 63.6(i)(4)(i)). The compliance date for the EGUs at this plant is November 1, 2015.

LG&E submitted a CAIR permit application on April 29, 2014 and submitted a revised application on May 30, 2014 for coal-fired boiler U4, U5, U6 and NGCC unit U15. In June, 2014, the U.S. Supreme Court filed a motion with the U.S. Court of Appeals for the

D.C. Circuit to lift the stay of the Cross State Air Pollution Rule. While the Court considers the motion, CAIR remains in place and no immediate action from States or affected sources is expected.

The existing emission unit U4, U5, U6, U7, U8, U10, IA1 (previous U9), two parts washers of IA2 (previous U12), and U14 shall be shut down within the contemporaneous period of the NGCC unit construction project in order to have their emission decreases to be eligible for PSD/NSR netting analysis. According to 40 CFR 52.21(b)(3)(ii), the contemporaneous period is defined as “between the date five years before construction on the particular change commences and the date that the increase from the particular change occurs”. In this permit the term “operational” means “normal operations” as defined in 40 CFR 52.21.

U6 Comments

The emission standards, monitoring, record keeping, and reporting requirements only apply to the boiler E5 (not the coal bunker E6) unless indicated.

LG&E’s proposal for removing COMS for Unit 3 and 4 at Mill Creek station was accepted in a letter from EPA dated Feb. 28, 2007. The District accordingly approved LG&E’s request for removing COMS for Unit 4, 5, and 6 for Cane Run providing PM CEMS are appropriately installed for these units.

The SO₂ and PM emissions cannot meet the standards uncontrolled. The owner or operator is required to operate the control devices to meet the applicable limits for SO₂ and PM.

For the coal silos (E6), the owner or operator has shown, by worst-case calculations without allowance for a control device, that the hourly uncontrolled PM emission standard cannot be exceeded; therefore, no additional monitoring, recordkeeping, or reporting is required to demonstrate compliance with the applicable PM standards.

LG&E Mill Creek submitted their TAC Environmental Acceptability Demonstration to the District on December 28, 2006, March 25, 2008, April 9, 2010, April 2, 2012, and May 13, 2014. Compliance with the STAR EA Goals was demonstrated in the source’s EA Demonstrations. SCREEN3 air dispersion modeling was performed for each emission unit that has non-de minimis TAC emissions. The table under U4 Comment 5 demonstrates that the carcinogen risk and non-carcinogen risk values, calculated using the District approved PTE for each unit and the SCREEN model results from the source’s EA Demonstration, comply with the STAR EA goals required in Regulation 5.21 controlled.

The coal-fired boilers are subject to 40 CFR Part 64 – Compliance Assurance Monitoring (CAM) for Major Stationary Source since SO2, PM, and NOx emissions from each of the boilers may be greater than the major source threshold and control devices are required to achieve compliance with standards. On 8/18/2014, LG&E submitted a revised CAM Plan in which SO2 and NOx CEMS are used for compliance demonstration. PM CEMS is used to demonstrate compliance or provide an indication of continuous PM control.
1. The compliance reports are due on or before the following dates of each calendar year: Reporting Period Report Due Date

January 1^st through March 31^th May 30^th April 1^st through June 30^th August 29^th

July 1^st through September 30^th November 29^th

October 1^st through December 31^st March 1^st

Boiler (E5) has TAC emission standards since its EA Demonstration was based on controlled PTE. If the controlled PTE for the TAC is less than de minimis level, use De Minimis as limit. If the controlled PTE for the TAC is greater than de minimis level, modeling results were used to calculate risk value to compare to the EA Goals. In this case, control PTE is used as limit. TAC emissions for the coal bunker (E2) are de minimis according to Regulation 5.21, section 2.1.

This unit is equipped with CEMS for NOx, SO2, and PM. According to the District’s letter dated November 1, 2005, parametric monitoring of the ESP, FGD, and PJFF injection for this unit is removed as such monitoring would no longer be required for demonstration of compliance.

According to 40 CFR 63.9984(b), the compliance date for an existing EGU is April 16, 2015. The District approved LG&E’s request for the extension of the compliance date per (40 CFR 63.6(i)(4)(i)). The compliance date for the EGUs at this plant is November 1, 2015.

LG&E submitted a CAIR permit application on April 29, 2014 and submitted a revised application on May 30, 2014 for coal-fired boiler U4, U5, U6 and NGCC unit U15. In June, 2014, the U.S. Supreme Court filed a motion with the U.S. Court of Appeals for the

D.C. Circuit to lift the stay of the Cross State Air Pollution Rule. While the Court considers the motion, CAIR remains in place and no immediate action from States or affected sources is expected.

The existing emission unit U4, U5, U6, U7, U8, U10, IA1 (previous U9), two parts washers of IA2 (previous U12), and U14 shall be shut down within the contemporaneous period of the NGCC unit construction project in order to have their emission decreases to be eligible for PSD/NSR netting analysis. According to 40 CFR 52.21(b)(3)(ii), the contemporaneous period is defined as “between the date five years before construction on the particular change commences and the date that the increase from the particular change occurs”. In this permit the term “operational” means “normal operations” as defined in 40 CFR 52.21.

U7 Comments

For E9, E10, E11, E12, E13, E14, E22, E23, and E24, it has been demonstrated that the PM emissions cannot exceed the PM standards specified in Regulation 7.08 uncontrolled.

The limit of 25 tons per year for PM is included in the permit as non-attainment NSR avoidance limits. This emission standard comes from their construction permit C-0126- 1002-14, which was issued in August, 2014 to replace construction permit 66-86, 67-86, 68-86, 69-86, 70-86, 71-86, 72-86, 73-86, 74-86, 75-86, 76-86, and 77-86. The uncontrolled combined PM emissions from E9, E10, E11, E13, E14, and E16 may exceed this PM emission limit. Therefore the owner or operator is required to operate the control devices at all times that the units are in operation. Control devices for the pug mill mixer (E12) are required to be operated at all times because of visible emissions and TAC emissions.

This HEPA filter (C14b for E12) is installed in order to control visible emissions. According to Agreed Board Order No. 12-01, the owner or operator is required to conduct hourly visible emission surveys and take corrective action when necessary. The opacity surveys can be performed on the building exhaust points since the process and its control devices vent inside the building.

Compliance with STAR has been demonstrated for this unit. See U1 Comment 5.

For the north bin silo (E9), the potential uncontrolled emissions of all TACs are below the de minimis threshold levels except for Chromium VI and Arsenic. In lieu of

performing environmental acceptability demonstration by modeling, the source is required to demonstrate that the Chromium VI and Arsenic emissions from this equipment are under de minimis level.

For the pug mill mixer (E12), the potential uncontrolled TACs are below the de minimis threshold levels except for Arsenic. The Arsenic emission can exceed its de minimis level (0.11 lb/yr and 0.00012 lb/hr) uncontrolled, but not controlled. The potential emissions of Arsenic after either the wet cyclone dust collector (C14a) or the HEPA filter (C14b) are below their de minimis levels. The pug mill mixer is required to be controlled by C14a and/or C14b at all time with respect to STAR compliance. Compliance with Specific Condition S1.b.ii for opacity will ensure the compliance with STAR.

This unit has been modified per construction permit 119-07-C for lime screw conveyor (E22), flyash screw conveyor (E23), and line/flyash screw conveyor (E24); permit 30501-11-C for Unit 4 & 5 SPP pug mill mixer wet cyclone (C14a), 31791-11-C for north bin silo baghouse (C11), and permit 34410-12-C Unit 4 & 5 SPP pug mill mixer HEPA filter (C14b).

The existing emission unit U4, U5, U6, U7, U8, U10, IA1 (previous U9), two parts washers of IA2 (previous U12), and U14 shall be shut down within the contemporaneous period of the NGCC unit construction project in order to have their emission decreases to be eligible for PSD/NSR netting analysis. According to 40 CFR 52.21(b)(3)(ii), the contemporaneous period is defined as “between the date five years before construction on the particular change commences and the date that the increase from the particular change occurs”. In this permit the term “operational” means “normal operations” as defined in 40 CFR 52.21.

U8 Comments

It has been demonstrated that the PM emissions for this unit cannot exceed the PM standards specified in Regulation 7.08 uncontrolled.

The limit of 25 tons per year for PM is included in the permit as non-attainment NSR avoidance limits. This emission standard comes from their construction permit C-0126- 1002-14, which was re-issued in August, 2014 to replace construction permit 66-86, 67- 86, 68-86, 69-86, 70-86, 71-86, 72-86, 73-86, 74-86, 75-86, 76-86, and 77-86. The uncontrolled combined PM emissions from E9, E10, E11, E13, E14, and E16 may exceed this PM emission limit. Therefore the owner or operator is required to operate the control devices at all times that the units are in operation.

STAR Program does not apply to this unit since there are no TAC emissions from this unit.

The existing emission unit U4, U5, U6, U7, U8, U10, IA1 (previous U9), two parts washers of IA2 (previous U12), and U14 shall be shut down within the contemporaneous period of the NGCC unit construction project in order to have their emission decreases to be eligible for PSD/NSR netting analysis. According to 40 CFR 52.21(b)(3)(ii), the contemporaneous period is defined as “between the date five years before construction on the particular change commences and the date that the increase from the particular change occurs”.

The owner or operator shall maintain the required records for a minimum of 5 years and make the records readily available to the District upon request.

a. NO_x

General requirements: (40 CFR 60.4333)

1) The owner or operator must operate and maintain the stationary combustion turbine, air pollution control equipment, and monitoring equipment in a manner consistent with good air pollution control practices for minimizing emissions at all times including during startup, shutdown, and malfunction. (60.4333(a))

2) When an affected unit with heat recovery utilizes a common steam header with one or more combustion turbines, the owner or operator shall either: (60.4333(b))

(a) Determine compliance with the applicable NO_X emissions limits by measuring the emissions combined with the emissions from the other unit(s) utilizing the common heat recovery unit; or (60.4333(b)(1))

(b) Develop, demonstrate, and provide information satisfactory to the Administrator (EPA or the District) on methods for apportioning the combined gross energy output from the heat recovery unit for each of the affected combustion turbines. The Administrator may approve such demonstrated substitute methods for apportioning the combined gross energy output measured at the steam turbine whenever the demonstration ensures accurate estimation of emissions related under this part. (60.4333(b)(2))

The owner or operator shall install, maintain, calibrate and operate a continuous emission monitoring system (CEMS) for the measurement or calculation of nitrogen oxides in the flue gas, as follows: (NO_x RACT Plan – Amendment 2) (40 CFR 60.4335(b) or 4340(b)(1)) (See Comment 5)

1) Install, certify, maintain, and operate a continuous emission monitoring system (CEMS) consisting of a NO_X monitor and a diluent gas (oxygen (O₂) or carbon dioxide (CO₂)) monitor, to determine the hourly NO_x emission rate in parts per million (ppm) or pounds per million British thermal units (lb/MMBtu); (40 CFR 60.4335(b)(1))

2) For units complying with the output-based standard, install, calibrate, maintain, and operate a fuel flow meter (or flow meters) to continuously measure the heat input to the affected unit; (40 CFR 60.4335(b)(2))

3) For units complying with the output-based standard, install, calibrate, maintain, and operate a watt meter (or meters) to continuously measure the gross electrical output of the unit in megawatt-hours; and (40 CFR 60.4335(b)(3))

The NO_x emission rate for combustion turbine GT-7A and GT-7B (U15) shall be determined using the methods and procedures specified in NO_x RACT Plan – Amendment 2 Appendix A, except that any reference to an annual average shall be read as a rolling 30-day average. (NO_x RACT Plan

– Amendment 2)

The NO_x CEMS shall meet the following requirements: (40 CFR 60.4345)

1) Each NO_x diluent CEMS must be installed and certified according to Performance Specification 2 (PS 2) in appendix B to this part, except the 7-day calibration drift is based on unit operating days,

not calendar days. With state approval, Procedure 1 in appendix F to this part is not required. Alternatively, a NO_X diluent CEMS that is installed and certified according to appendix A of part 75 of this chapter is acceptable for use under this subpart. The relative accuracy test audit (RATA) of the CEMS shall be performed on a lb/MMBtu basis. (40 CFR 60.4345(a))

2) As specified in § 60.13(e)(2), during each full unit operating hour, both the NO_X monitor and the diluent monitor must complete a minimum of one cycle of operation (sampling, analyzing, and data recording) for each 15-minute quadrant of the hour, to validate the hour. For partial unit operating hours, at least one valid data point must be obtained with each monitor for each quadrant of the hour in which the unit operates. For unit operating hours in which required quality assurance and maintenance activities are performed on the CEMS, a minimum of two valid data points (one in each of two quadrants) are required for each monitor to validate the NO_X emission rate for the hour. (40 CFR 60.4345(b))

3) Each fuel flowmeter shall be installed, calibrated, maintained, and operated according to the manufacturer’s instructions. Alternatively, with state approval, fuel flowmeters that meet the installation, certification, and quality assurance requirements of appendix D to part 75 of this chapter are acceptable for use under this subpart. (40 CFR 60.4345(c))

4) Each watt meter, steam flow meter, and each pressure or temperature measurement device shall be installed, calibrated, maintained, and operated according to manufacturer’s instructions. (40 CFR 60.4345(d))

5) The owner or operator shall develop and keep on-site a quality assurance (QA) plan for all of the continuous monitoring equipment described in paragraphs (a), (c), and (d) of this section. For the CEMS and fuel flow meters, the owner or operator may, with state approval, satisfy the requirements of this paragraph by implementing the QA program and plan described in section 1 of appendix B to part 75 of this chapter. (40 CFR 60.4345(e))

The owner or operator will identify excess emissions using the following guidelines: (40 CFR §60.4350)

1) All CEMS data must be reduced to hourly averages as specified in

§60.13(h). (40 CFR §60.4350(a))

2) For each unit operating hour in which a valid hourly average, as described in §60.4345(b), is obtained for both NO_X and diluent monitors, the data acquisition and handling system must calculate and record the hourly NO_X emission rate in units of ppm or lb/MMBtu, using the appropriate equation from Method 19 in appendix A of this part. For any hour in which the hourly average O₂ concentration exceeds 19.0 percent O₂ (or the hourly average CO₂ concentration is less than 1.0 percent CO₂), a diluent cap value of 19.0 percent O₂ or 1.0 percent CO₂ (as applicable) may be used in the emission calculations. (40 CFR §60.4350(b))

3) Correction of measured NO_X concentrations to 15 percent O₂ is not allowed. (40 CFR §60.4350(c))

4) If the owner or operator have installed and certified a NO_X diluent CEMS to meet the requirements of part 75 of this chapter, states can approve that only quality assured data from the CEMS shall be used to identify excess emissions under this subpart. Periods where the missing data substitution procedures in subpart D of part 75 are applied are to be reported as monitor downtime in the excess emissions and monitoring performance report required under

§60.7(c). (40 CFR §60.4350(d))

5) All required fuel flow rate, steam flow rate, temperature, pressure, and megawatt data must be reduced to hourly averages. (40 CFR

§60.4350(e))

6) Calculate the hourly average NO_X emission rates, in units of the emission standards under §60.4320, using either ppm for units complying with the concentration limit or the following equation for units complying with the output based standard: (40 CFR

§60.4350(f))

(a) For combined-cycle and combined heat and power complying with the output-based standard, use Equation 1 of this subpart, except that the gross energy output is calculated as the sum of the total electrical and mechanical energy generated by the combustion turbine, the additional electrical or mechanical energy (if any) generated by the steam turbine following the heat recovery steam generator, and 100 percent of the total useful thermal energy output that is not used to generate additional electricity or mechanical output, expressed in equivalent MW, as in the following equations: (40 CFR §60.4350(f)(2))

(Eq. 1)

Where:

E = hourly NOx emission rate, in lb/MWh (NO_x)_h = hourly NOx emission rate, in lb/MMBtu

(HI)_h = hourly heat input rate to the unit, in MMBtu/hr, measured using the fuel flowmeters, e.g., calculated using Equation D-15a in appendix D to part 75 of this chapter, and

P = gross energy output of the combustion turbine in MW

(Eq. 2)

Where:

P = gross energy output of the stationary combustion turbine system (MW)

(PE)_t = electrical or mechanical energy output of the CT (MW)

(PE)_c = electrical or mechanical output of the steam turbine (MW)

(Eq. 3)

Where:

Ps = useful thermal energy of the system, measured relative to ISO conditions, not used to generate additional electric or mechanical output, in MW

Q = measured steam flow rate in lb/hr

H = enthalpy of steam at measured temperature and pressure relative to ISO conditions, in Btu/lb, and

3.413 x 10⁶ = conversion from Btu/hr to MW

Po = other useful heat recovery, measured relative to ISO conditions, not used for steam generation or performance enhancement of the combustion turbine.

7) For combined cycle and combined heat and power units with heat recovery, use the calculated hourly average emission rates from paragraph (f) of this section to assess excess emissions on a 30 unit operating day rolling average basis, as described in

§60.4380(b)(1). (40 CFR 60.4350(h))

When the Clean Air Interstate Rule or the applicable NO_x cap and trade program(s) are in effect, the owner or operator shall monitor the NOx emissions to demonstrate compliance the NO_x limitations or allowances as

specified in the effective rules. (Regulation 2.16, sections 4.1.9.1 and 4.1.9.2) (See Comment 9)

b. SO₂

The owner or operator shall monitor the total sulfur content of the fuel being fired in the turbine, except as provided in 40 CFR 60.4365. The sulfur content of the fuel must be determined using total sulfur methods described in § 60.4415. Alternatively, if the total sulfur content of the gaseous fuel during the most recent performance test was less than half the applicable limit, ASTM D4084, D4810, D5504, or D6228, or Gas Processors Association Standard 2377 (all of which are incorporated by reference, see § 60.17), which measure the major sulfur compounds, may be used. (40 CFR 60.4360)

If the owner or operator elects not to demonstrate sulfur content using options in 40 CFR 60.4365, and the fuel is supplied without intermediate bulk storage, the sulfur content value of the gaseous fuel must be determined and recorded once per unit operating day. (40 CFR 60.4370(b))

The owner or operator may elect not to monitor the total sulfur content of the fuel combusted in the turbine, if the fuel is demonstrated not to exceed potential sulfur emissions of 26 ng SO₂/J (0.060 lb SO₂/MMBtu) heat input for units located in continental areas and 180 ng SO₂/J (0.42 lb SO₂/MMBtu) heat input for units located in non-continental areas or a continental area that the Administrator determines does not have access to natural gas and that the removal of sulfur compounds would cause more environmental harm than benefit. The owner or operator must use one of the following sources of information to make the required demonstration: (40 CFR 60.4365)

1) The fuel quality characteristics in a current, valid purchase contract, tariff sheet or transportation contract for the fuel, specifying that the maximum total sulfur content for oil use in continental areas is 0.05 weight percent (500 ppmw) or less and

0.4 weight percent (4,000 ppmw) or less for non-continental areas, the total sulfur content for natural gas use in continental areas is 20 grains of sulfur or less per 100 standard cubic feet and 140 grains of sulfur or less per 100 standard cubic feet for non-continental areas, has potential sulfur emissions of less than less than 26 ng SO₂/J (0.060 lb SO₂/MMBtu) heat input for continental areas and has potential sulfur emissions of less than less than 180 ng SO₂/J (0.42 lb SO₂/MMBtu) heat input for non-continental areas; or (40 CFR 60.4365(a))

2) Representative fuel sampling data which show that the sulfur content of the fuel does not exceed 26 ng SO₂/J (0.060 lb SO₂/MMBtu) heat input for continental areas or 180 ng SO₂/J (0.42 lb SO₂/MMBtu) heat input for non-continental areas. At a minimum, the amount of fuel sampling data specified in section

2.3.1.4 or 2.3.2.4 of appendix D to part 75 of this chapter is required. (40 CFR 60.4365(b))

When the Clean Air Interstate Rule or the applicable SO₂ cap and trade program(s) are in effect, the owner or operator shall monitor the NOx emissions to demonstrate compliance the SO₂ limitations or allowances as specified in the effective rules. (Regulation 2.16, sections 4.1.9.1 and 4.1.9.2) (See Comment 9)

c. CO

The owner or operator shall install, maintain, calibrate and operate a continuous emission monitoring system (CEMS) for the measurement or calculation of CO in the flue gas. (Regulation 2.16, section 4.1.1) (See Comment 6)

(40 CFR 52.21(r)(6)(i)(c))

2) The owner or operator shall provide a copy of the information set out in 40 CFR 52.21(r)(6)(i) to the Administrator. Nothing in this paragraph (r)(6)(ii) shall be construed to require the owner or

operator of such a unit to obtain any determination from the Administrator before beginning actual construction. (40 CFR 52(r)(6)(ii))

3) The owner or operator shall monitor the emissions of any regulated NSR pollutant that could increase as a result of the project and that is emitted by any emissions unit identified in 40 CFR 52.21(r)(6)(i)(b), and calculate and maintain a record of the annual emissions, in tons per year on a calendar year basis, for a period of

S3. Reporting (Regulation 2.16, section 4.1.9.3)

The owner or operator shall submit quarterly compliance reports that include the information in this section.

a. General requirements

For each affected unit required to continuously monitor parameters or emissions, or to periodically determine the fuel sulfur content under this subpart, the owner or operator must submit reports of excess emissions and monitor downtime, in accordance with 40 CFR 60.7(c), as specified in S3.a.iii. Excess emissions must be reported for all periods of unit operation, including start-up, shutdown, and malfunction. (40 CFR 60.4375(a))

Each owner or operator required to install a continuous monitoring device shall submit excess emissions and monitoring systems performance report (excess emissions are defined in applicable subparts) and-or summary report form (see paragraph (d) of this section) to the Administrator semiannually, except when: more frequent reporting is specifically required by an applicable subpart; or the Administrator, on a case-by-case basis, determines that more frequent reporting is necessary to accurately assess the compliance status of the source. All reports shall be postmarked by the 30th day following the end of each six-month period. Written reports of excess emissions shall include the following information: (40 CFR 60.7(c))

1) The magnitude of excess emissions computed in accordance with § 60.13(h), any conversion factor(s) used, and the date and time of commencement and completion of each time period of excess emissions. The process operating time during the reporting period. (40 CFR 60.7(c)(1))

For turbines using continuous emission monitoring, periods of excess emissions and monitor downtime that must be reported are defined as follows: (40 CFR 60.4380(b))

1) An excess emissions is any unit operating period in which the 4- hour or 30-day rolling average NO_X emission rate exceeds the applicable emission limit in § 60.4320. For the purposes of this subpart, a “4-hour rolling average NO_X emission rate” is the arithmetic average of the average NO_X emission rate in ppm or ng/J (lb/MWh) measured by the continuous emission monitoring equipment for a given hour and the three unit operating hour average NO_X emission rates immediately preceding that unit operating hour. Calculate the rolling average if a valid NO_X emission rate is obtained for at least 3 of the 4 hours. For the purposes of this subpart, a “30-day rolling average NO_X emission rate” is the arithmetic average of all hourly NO_X emission data in ppm or ng/J (lb/MWh) measured by the continuous emission monitoring equipment for a given day and the twenty-nine unit operating days immediately preceding that unit operating day. A new 30-day average is calculated each unit operating day as the

average of all hourly NO_X emissions rates for the preceding 30 unit operating days if a valid NO_X emission rate is obtained for at least 75 percent of all operating hours. (40 CFR 60.4380(b)(1))

2) A period of monitor downtime is any unit operating hour in which the data for any of the following parameters are either missing or invalid: NO_X concentration, CO₂ or O₂ concentration, fuel flow rate, steam flow rate, steam temperature, steam pressure, or megawatts. The steam flow rate, steam temperature, and steam pressure are only required if the owner or operator will use this information for compliance purposes. (40 CFR 60.4380(b)(2))

c. SO₂

The owner or operator shall identify all periods of exceeding a SO₂ emission standard during a quarterly reporting period. The quarterly compliance report shall include the following:

The owner or operator shall submit a report to the Administrator within 30 days after the new emission units become operational and begins to emit a particular pollutant, which include the date when the existing emission unit U4, U5, U6, U7, U8, U10, IA1 (previous U9), two parts washers of IA2 (previous U12), and U14 shut down, and the date when the new emission unit U15, U16, and U18 become operational and begins to emit a particular pollutant. Any replacement unit that requires shakedown becomes operational only after a reasonable shakedown period, not to exceed 180 days. (Regulation 2.05) (40 CFR 52.21(b)(3)(viii)) (See Comment 8)

S4. Testing (Regulation 2.16, section 4.1.9.1)

a. General testing requirement:

Unless otherwise required by any other applicable regulations, the following testing requirements apply to performance tests required by this permit:

The owner or operator shall perform tests using an EPA Reference Method performance test within 180 days of becoming operational and begins to emit a particular pollutant on the inlet and outlet of the control device. The test shall be performed at 90% or higher of maximum capacity, or allowable/permitted capacity, or at a level of capacity which results in the greatest emissions and is representative of the operations. Failure to perform the test, at maximum capacity, allowable/permitted capacity, or at a level of capacity which resulted in the greatest emissions, may necessitate a re-test or necessitate a revision of the allowable/permitted capacity of the process equipment depending upon the difference between the testing results and the limit.

The owner or operator shall submit written compliance test plans (protocol). They shall include the EPA test methods, the process operating parameters that will be monitored during the performance test, and the control device performance indicators (e.g. pressure drop, minimum combustion chamber temperature) that will be monitored during the performance test. The compliance test plans shall be furnished to the District at least 30 days prior to the actual date of the performance test. Attached to the permit is a Protocol Checklist for Performance Test for the information to be submitted in the protocol.
1. The owner or operator shall be responsible for obtaining and analyzing audit samples when the EPA Reference Method is used to analyze samples to demonstrate compliance with the source’s emission regulation. The furnishing, ownership, and processing of the audit samples and their results shall be described in the protocol. The audit samples shall be available for verification by the District during the onsite testing. (See Comment 9)

The owner or operator shall provide the District at least 10 days prior notice of any performance test to afford the District the opportunity to have an observer present.

The owner or operator shall furnish the District with a written report of the results of the performance test within 60 days following the actual date of completion of the performance test.

The owner or operator shall provide written notification to the District of the actual date of initial startup. The written notification shall be postmarked within 15 days of becoming operational and begins to emit a particular pollutant.

b. Determination of monitoring parameters

The owner or operator shall determine the appropriate monitoring parameters for each of the catalytic oxidizers (C23 and C24), which may include but not be limited to CO CEMS readings, pressure drop, temperature, PH value, etcetera, that will be used as indicators of normal operation of the control devices.

The owner or operator shall monitor and record the appropriate monitoring parameters for the thermal catalytic oxidizers at least once each per operating day. The owner or operator shall establish an appropriate parameter range for the normal operation of the catalytic oxidizers after ninety (90) consecutive days of observation after becoming operational.

The owner or operator shall submit to the District the established appropriate ranges of the monitoring parameters for each catalytic oxidizer. The report shall be submitted within 30 days following the end of the 90 day monitoring period.

c. NOx

The owner or operator must conduct an initial performance test, as required in 40 CFR 60.8. (40 CFR 60.4400(a))
If the owner or operator elects to install and certify a NO_X-diluent CEMS under 40 CFR 60.4345, then the initial performance test required under 40 CFR 60.8 may be performed in the following alternative manner: (40 CFR 60.4405)

1) Perform a minimum of nine RATA reference method runs, with a minimum time per run of 21 minutes, at a single load level, within plus or minus 25 percent of 100 percent of peak load. The ambient temperature must be greater than 0 ° F during the RATA runs. (40 CFR 60.4405(a))

2) For each RATA run, concurrently measure the heat input to the unit using a fuel flow meter (or flow meters) and measure the electrical and thermal output from the unit. (40 CFR 60.4405(b))

3) Use the test data both to demonstrate compliance with the applicable NO_X emission limit under § 60.4320 and to provide the required reference method data for the RATA of the CEMS described under § 60.4335. (40 CFR 60.4405(c))

4) Compliance with the applicable emission limit in § 60.4320 is achieved if the arithmetic average of all of the NO_X emission rates for the RATA runs, expressed in units of ppm or lb/MWh, does not exceed the emission limit. (40 CFR 60.4405(d))

The performance test must be done at any load condition within plus or minus 25 percent of 100 percent of peak load. The owner or operator may perform testing at the highest achievable load point, if at least 75 percent of peak load cannot be achieved in practice. The owner or operator must conduct three separate test runs for each performance test. The minimum time per run is 20 minutes. (40 CFR 60.4400(b))

1) If the stationary combustion turbine combusts both oil and gas as primary or backup fuels, separate performance testing is required for each fuel. (40 CFR 60.4400(b)(1))

2) If water or steam injection is used to control NO_X with no additional post-combustion NO_X control and the owner or operator choose to monitor the steam or water to fuel ratio in accordance with § 60.4335, then that monitoring system must be operated concurrently with each EPA Method 20 or EPA Method 7E run and must be used to determine the fuel consumption and the steam or water to fuel ratio necessary to comply with the applicable § 60.4320 NO_X emission limit. (40 CFR 60.4400(b)(3))

		3) Compliance with the applicable emission limit in § 60.4320 must be demonstrated at each tested load level. Compliance is achieved if the three-run arithmetic average NO_X emission rate at each tested level meets the applicable emission limit in § 60.4320. (40
		CFR 60.4400(b)(4))
		4) If the owner or operator elects to install a CEMS, the performance
		evaluation of the CEMS may either be conducted separately or (as
		described in § 60.4405) as part of the initial performance test of the
		affected unit. (40 CFR 60.4400(b)(5))
		5) The ambient temperature must be greater than 0 °F during the
		performance test. (40 CFR 60.4400(b)(6))

d. SO₂

If the owner or operator is exempt from monitoring the total sulfur content of the fuel according to 40 CFR 60.4365, there is no performance testing requirements for this gas turbine.

If the owner or operator is not exempt from monitoring the total sulfur content of the fuel according to 40 CFR 60.4365, and elects to monitor the total sulfur content of the fuel being fired in the turbine, the owner or operator must conduct an initial performance test, as required in 40 CFR

60.8. Subsequent SO₂ performance tests shall be conducted on an annual basis (no more than 14 calendar months following the previous performance test). There are three methodologies that the owner or operator may use to conduct the performance tests. (40 CFR 60.4415(a))

1) If the owner or operator chooses to periodically determine the sulfur content of the fuel combusted in the turbine, a representative fuel sample would be collected following ASTM D5287 (incorporated by reference, see § 60.17) for natural gas or ASTM D4177 (incorporated by reference, see § 60.17) for oil. Alternatively, for oil, the owner or operator may follow the procedures for manual pipeline sampling in section 14 of ASTM D4057 (incorporated by reference, see § 60.17). The fuel analyses of this section may be performed either by the owner or operator, a service contractor retained by the owner or operator, the fuel vendor, or any other qualified agency. Analyze the samples for the total sulfur content of the fuel using: (40 CFR 60.4415(a)(1))

(a) For liquid fuels, ASTM D129, or alternatively D1266, D1552, D2622, D4294, or D5453 (all of which are incorporated by reference, see § 60.17); or (40 CFR 60.4415(a)(1)(i))

(b) For gaseous fuels, ASTM D1072, or alternatively D3246, D4084, D4468, D4810, D6228, D6667, or Gas Processors Association Standard 2377 (all of which are incorporated by reference, see § 60.17). (40 CFR 60.4415(a)(1)(ii))

2) Measure the SO₂ concentration (in parts per million (ppm)), using EPA Methods 6, 6C, 8, or 20 in appendix A of this part. In addition, the American Society of Mechanical Engineers (ASME) standard, ASME PTC 19–10–1981–Part 10, “Flue and Exhaust Gas Analyses,” manual methods for sulfur dioxide (incorporated by reference, see § 60.17) can be used instead of EPA Methods 6 or 20. For units complying with the output based standard, concurrently measure the stack gas flow rate, using EPA Methods 1 and 2 in appendix A of this part, and measure and record the electrical and thermal output from the unit. Then use the following equation to calculate the SO₂ emission rate: (40 CFR 60.4415(a)(2))

(Eq.6)

Where:

E = SO₂ emission rate, in lb/MWh

1.664 x 10 ^-7= conversion constant, in lb/dscf-ppm (SO₂)_c= average SO₂ concentration for the run, in ppm Q_std= stack gas volumetric flow rate, in dscf/hr

P = gross electrical and mechanical energy output of the combustion turbine, in MW (for simple-cycle operation), for combined-cycle operation, the sum of all electrical and mechanical output from the combustion and steam turbines, or, for combined heat and power operation, the sum of all electrical and mechanical output from the combustion and steam turbines plus all useful recovered thermal output not used for additional electric or mechanical generation, in MW, calculated according to § 60.4350(f)(2); or

3) Measure the SO₂ and diluent gas concentrations, using either EPA Methods 6, 6C, or 8 and 3A, or 20 in appendix A of this part. In addition, the owner or operator may use the manual methods for sulfur dioxide ASME PTC 19–10–1981–Part 10 (incorporated by reference, see § 60.17). Concurrently measure the heat input to the unit, using a fuel flowmeter (or flowmeters), and measure the electrical and thermal output of the unit. Use EPA Method 19 in appendix A of this part to calculate the SO₂ emission rate in lb/MMBtu. Then, use Equations 1 and, if necessary, 2 and 3 in §

60.4350(f) to calculate the SO₂ emission rate in lb/MWh. (40 CFR 60.4415(a)(3))

e. VOC

The owner or operator shall perform an EPA Reference Method 25A performance test within 180 days of becoming operational and begins to emit a particular pollutant, and then test every 10 years thereafter based on the date of the previous stack test, in order to determine emission rate for VOC.

f. HAP

The owner or operator shall perform a performance test within 180 days of becoming operational and begins to emit a particular pollutant, and then test every

10 years thereafter based on the date of the previous stack test, in order to determine emission rate for Formaldehyde, using EPA Reference Method 320 or 323, ARB Method 430, SW-846 Method 0011, or other test methods for Formaldehyde approved by the District.

U15 Comments

The District has determined that the SO₂ standard under Regulation 7.09 (28.63 grains/100 dscf) is less stringent than the standard under 40 CFR 60, Subpart KKKK (0.06 lb/MMBtu). According to Regulation 7.02, section 5, the combustion turbines are not subject to the SO₂ standard under Regulation 7.09. Also the combustion process in the turbines is greater than 1,300°F for 0.5 second. Therefore there is no monitoring, record keeping, and reporting requirements with respect to the CO standard under Regulation 7.09.

There is a reasonable possibility that this project may result in a significant emissions increase of CO and VOC, since the uncontrolled potential CO and VOC net emission increases for this construction project exceed their PSD/NSR significant emission rates, but the controlled CO and VOC emission increases cannot exceed PSD/NSR significant emission rates. The plant-wide CO and VOC emission standards are determined with the emission decreases during the contemporaneous period (CO = 410.8 tons; VOC =

57.0 tons) and the PSD/NSR significant emission rate (CO = 100 tons; VOC = 40 tons). The 12 consecutive month rolling emissions include the annual emissions required by 40 CFR 52.21(r)(6)(iii).

The plant-wide uncontrolled potential emissions for HAPs, except for Formaldehyde are below major source thresholds for HAPs. The plant-wide potential emissions for any HAP, controlled by the catalytic oxidizers, are below major source thresholds for HAP. Therefore the source is not subject to the major source MACT for combustion turbines – 40 CFR 63 Subpart YYYY.
LG&E submitted their TAC Environmental Acceptability Demonstration to the District on December 28, 2006, March 25, 2008, and April 9, 2010, in which the source has demonstrated compliance with the EA Goals. The proposed project is natural gas-fired NGCC unit. Per Regulation 5.01, section 1.6.7, the TAC emissions from the combustion of natural gas are “de minimis emissions”.

According to 40 CFR 60.4335 and 60.4340, depending on whether a water or steam injection is used for NOx control, the owner or operator may elect to use one of the following: continuous monitoring system for fuel and water/steam, continuous emission monitoring system (CEMS), performance test, or continuous parameter monitoring system to demonstrate compliance with NOx limit. LG&E has elected to use NOx CEMS for the units.

The owner or operator elected to utilize a CO CEMS to monitor CO emissions and demonstrate compliance with the PSD avoidance emission cap.

Per an EPA rule change (“Restructuring of the Stationary Source Audit Program.” Federal Register 75:176 (September 13, 2010) pp 55636-55657), sources became responsible for obtaining the audit samples directly from accredited audit sample suppliers, not the regulatory agencies.

The existing emission unit U4, U5, U6, U7, U8, U10, IA1 (previous U9), two parts washers of IA2 (previous U12), and U14 shall be shut down within the contemporaneous period of the NGCC unit construction project in order to have their emission decreases to be eligible for PSD/NSR netting analysis. According to 40 CFR 52.21(b)(3)(ii), the contemporaneous period is defined as “between the date five years before construction on the particular change commences and the date that the increase from the particular change occurs”. In this permit the term “operational” means “normal operations” as defined in 40 CFR 52.21.

LG&E submitted a CAIR permit application on April 29, 2014 and submitted a revised application on May 30, 2014 for coal-fired boiler U4, U5, U6 and NGCC unit U15. In June, 2014, the U.S. Supreme Court filed a motion with the U.S. Court of Appeals for the

D.C. Circuit to lift the stay of the Cross State Air Pollution Rule. While the Court considers the motion, CAIR remains in place and no immediate action from States or affected sources is expected.

In an email dated 2/6/2014, LG&E notified the District that the dew point heater (U17), previously permitted by construction permit 35274-12-C, will not be constructed.

The owner or operator shall submit the re-evaluated EA demonstration to the District within 6 months after a change of a raw material as described in Specific Condition S2.f.ii.

U16 Comments

The equipment is subject to 40 CFR 60, Subpart D_c – Standards of Performance for Small Industrial-Commercial-Institutional Steam Generating Units, due to the commencement date of construction (after June 9, 1989) and the heat input capacity (less than 100 MMBtu/hr, but greater than 10 MMBtu/hr).

The plant-wide potential emission for HAP, controlled by catalytic oxidizer, is below major source thresholds for HAP. Therefore the boilers at this source are not subject to the major source MACT for boilers 40 CFR 63 Subpart DDDDD. This natural gas-fired boiler is not subject to 40 CFR 63, Subpart JJJJJJ – Industrial, Commercial, and Institutional Boilers and Process Heaters at Area Sources, according to 40 CFR 63.11195(e).

A one-time PM and SO₂ compliance demonstration has been performed for the boiler, using AP-42 emission factors and combusting natural gas, and the emission standards under Regulation 7.06 for PM and SO₂ cannot be exceeded when combusting natural gas.

The District has determined that using a natural gas fired boiler will inherently meet the 20% opacity standard. Therefore, the company is not required to perform periodic monitoring to demonstrate compliance with the opacity standard when combusting natural gas.

Per Regulation 5.01, section 1.6.7, the TAC emissions from the combustion of natural gas are considered to be “de minimis emissions” by the District.

IA-EG Comment

This unit is is subject to 40 CFR 63, Subpart ZZZZ, National Emissions Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines, because it involves a stationary reciprocating internal combustion engine (RICE) located at a major source of HAP emissions. The proposed new stationary RICE meets the definition in 40 CFR 63.6675 of an emergency stationary RICE, which, per 40 CFR 63.6590(b)(1)(i), does not have to meet the requirements of 40 CFR 63 Subpart ZZZZ and of 40 CFR 63 Subpart A.

The associated storage tank for diesel fuel is exempt from District permitting requirements in accordance with Regulation 1.02, section 3.9.2.

Per an EPA rule change (“Restructuring of the Stationary Source Audit Program.” Federal Register 75:176 (September 13, 2010) pp 55636-55657), sources became responsible for obtaining the audit samples directly from accredited audit sample suppliers, not the regulatory agencies.

Potential emissions for this permitted operation are greatest for nitrogen oxides (NO_x). Based on AP-42 Emission Factors and 500 hours per year for an emergency generator, as defined by EPA, the potential NO_x emissions for this permitted operation is less than 5 tons per year.

Appendix A to NO_x RACT Plan (Requirements for NO_x CEMS)

I. General Operating Requirements

A. Primary measurement requirements. The LG&E/CRGS shall, for each utility boiler and combustion turbine (GT-7A and GT-7B), install, certify, operate, and maintain, in accordance with the requirements of 40 CFR 75, an oxides of nitrogen (NO_x) continuous emission monitoring system (CEMS), consisting of a NO_x pollutant concentration monitor and an oxygen (O₂) or carbon dioxide (CO₂) diluent gas monitor, with an automated data acquisition and handling system for measuring and recording NO_x concentration (in parts per million (ppm)), O₂ or CO₂ concentration (in percent O₂ or CO₂) and NO_x emission rate (in lb/mmBtu heat input) discharged to the atmosphere. Any reference in this Appendix to an annual average shall be read as a rolling 30-day average. The LG&E/CRGS shall account for total NO_x emissions, both nitrogen oxide (NO) and nitrogen dioxide (NO₂), either by monitoring for both NO and NO₂ or by monitoring for NO only and adjusting the emissions data to account for NO₂.

B. Primary equipment performance requirements. The LG&E/CRGS shall ensure that each CEMS used to demonstrate compliance with the NO_x emission limit meets the equipment, installation, and performance specifications in 40 CFR 75 Appendix A, and is maintained according to the quality assurance and quality control procedures in 40 CFR 75 Appendix B.

C. Primary equipment hourly operating requirements.
The LG&E/CRGS shall ensure that all CEMS are in operation and monitoring the emissions from the associated utility boiler and combustion turbine (GT-7A and GT-7B) at all times that the utility boiler and combustion turbine (GT-7A and GT-7B) combusts any fuel except during a period of any of the following:
1. Calibration, quality assurance, or preventive maintenance, any of which is performed pursuant to 40 CFR 75.21, 40 CFR 75

Appendix B, District regulations, District permit conditions, or this NO_x RACT Plan, or

Repair, backups of data from the data acquisition and handling system, or recertification, any of which is performed pursuant to 40 CFR 75.20.
The LG&E/CRGS shall ensure that the following requirements are met:
1. Each CEMS and component thereof is capable of completing a minimum of one cycle of operation (sampling, analyzing, and data recording) for each successive 15-minute interval. The LG&E/CRGS shall reduce all volumetric flow, CO₂ concentration, O₂ concentration, NO_x concentration, and NO_x emission rate data collected by the monitors to hourly averages. Hourly averages shall be computed using at least one data point in each 15- minute quadrant of an hour during which the utility boiler and combustion turbine (GT-7A and GT-7B) combusted fuel during that quadrant of the hour. Notwithstanding this requirement, an hourly average may be computed from at least two data points separated by a minimum of 15 minutes (where the unit operates for more than one quadrant of the hour) if data are unavailable as a result of the performance of any activity specified in paragraph I.C.1. of this Appendix. The LG&E/CRGS shall use all valid measurements or data points collected during an hour to calculate the hourly averages. All data points collected during an hour shall be, to the extent practicable, evenly spaced over the hour.
2. Failure of a CO₂ or O₂ diluent concentration monitor, flow monitor, or NO_X pollutant concentration monitor to acquire the minimum number of data points for calculation of an hourly average shall result in the failure to obtain a valid hour of data and the loss of such component data for the entire hour. An hourly average NO_x emission rate in lb/mmBtu heat input is valid only if the minimum number of data points are acquired by both the pollutant concentration monitor (NO_x) and the diluent monitor (CO₂ or O₂). If a valid hour of data is not obtained, the owner or operator shall estimate and record emissions, moisture, or flow data for the missing hour by means of the automated data acquisition and handling system, in accordance with the applicable procedure for missing data substitution in 40 CFR 75 Subpart D.

D. Optional backup monitor requirements. If the LG&E/CRGS chooses to use two or more CEMS, each of which is capable of monitoring the same stack or duct at a specific utility boiler and combustion turbine (GT-7A and GT-7B), then the LG&E/CRGS shall designate one CEMS as the primary monitoring system and shall record this designation in the monitoring plan. The LG&E/CRGS shall designate any other CEMS as a backup CEMS in the monitoring plan. Any other backup CEMS shall be designated as a redundant backup CEMS, non-redundant backup CEMS, or reference method CEMS, as described in 40 CFR 75.20(d).

When the certified primary monitoring system is operating and not out-of-control as defined in 40 CFR 75.24, only data from the certified primary monitoring system shall be reported as valid, quality-assured data. Thus, data from a backup CEMS may be reported as valid, quality-assured data only when a backup CEMS is operating and not out-of-control as defined in 40 CFR 75.24 or in the applicable reference method in 40 CFR 60 Appendix A and when the certified primary monitoring system is not operating or is operating but out-of-control. A particular monitor may be designated both as a certified primary monitor for one unit and as a certified redundant backup monitor for another unit.

E. Minimum measurement capability requirements. Each CEMS and component thereof shall be capable of accurately measuring, recording, and reporting data, and shall not incur a full scale exceedance, except as provided in section 2.1.2.5 of 40 CFR 75 Appendix A.

F. The LG&E/CRGS shall not operate a utility boiler and combustion turbine (GT- 7A and GT-7B) so as to discharge, or allow to be discharged, emissions of NO_x to the atmosphere without accounting for all such emissions in accordance with the methods and procedures specified in this Appendix.

G. The LG&E/CRGS shall not disrupt the CEMS, any portion thereof, or any other approved emission monitoring method, and thereby avoid monitoring and recording NO_x emissions discharged into the atmosphere, except for periods of recertification or periods when calibration, quality assurance testing, or maintenance is performed in accordance with the provisions of this Appendix.

H. The LG&E/CRGS shall not retire or permanently discontinue use of the CEMS, any component thereof, or any other approved emission monitoring system under this Appendix except under any one of the following circumstances:
1. The LG&E/CRGS is monitoring NO_x emissions from the utility boiler and combustion turbine (GT-7A and GT-7B) with another certified monitoring system approved in accordance with the provisions of paragraph I.D. of this Appendix, or
2. The LG&E/CRGS submits notification of the date of certification testing of a replacement monitoring system.

I. The quality assurance and quality control requirements in 40 CFR 75.21 that applies to NO_x pollutant concentration monitors and diluent gas monitors shall be met.

J. Moisture correction. If a correction for the stack gas moisture content is needed to properly calculate the NO_x emission rate in lb/mmBtu heat input (i.e., if the NO_x pollutant concentration monitor measures on a different moisture basis from the diluent monitor), LG&E/CRGS shall either report a fuel-specific default moisture value for each utility boiler and combustion turbine (GT-7A and GT-7B) operating hour, as provided in 40 CFR 75.11(b)(1), or shall install, operate,

maintain, and quality assure a continuous moisture monitoring system, as defined in 40 CFR 75.11(b)(2). Notwithstanding this requirement, if Equation 19-3, 19-4 or 19-8 in Method 19 in Appendix A to 40 CFR Part 60 is used to measure NO_x emission rate, the following fuel-specific default moisture percentages shall be used in lieu of the default values specified in 40 CFR 75.11(b)(1): 5.0%, for anthracite coal; 8.0% for bituminous coal; 12.0% for sub-bituminous coal; 13.0% for lignite coal; and 15.0% for wood.

II. Specific Provisions for Monitoring NO_x Emission Rate (NO_x and diluent gas monitors)

A. The LG&E/CRGS shall meet the general operating requirements in 40 CFR 75.10 for a NO_x CEMS for each utility boiler and combustion turbine (GT-7A and GT- 7B). The diluent gas monitor in the NO_x CEMS may measure either O₂ or CO₂ concentration in the flue gases.

B. The LG&E/CRGS shall calculate hourly and rolling 30-day NO_x emission rates by combining the NO_x concentration (in ppm), diluent concentration (in percent O₂ or CO₂), and percent moisture (if applicable) measurements according to the procedures in 40 CFR 75 Appendix F.

III. Monitoring plan

The LG&E/CRGS shall prepare and maintain a monitoring plan as specified in 40 CFR 75.53. The monitoring plan shall be submitted to the District no later than 45 days prior to the first scheduled certification test.

IV. Recordkeeping Provisions

A. The LG&E/CRGS shall maintain for each utility boiler and combustion turbine (GT-7A and GT-7B) a file of all measurements, data, reports, and other information required by this Appendix at the stationary source in a form suitable for inspection for at least 5 years from the date of each record.

Attachment C – Plant-wide Odor, Fugitive Dust, and Maintenance Emissions Control Plan Cane Run Generating Station

(Submitted 2/13/2013 and 8/16/2013; Adopted by the Board 4/17/2013 and 11/20/2013)

Executive Summary

Louisville Gas and Electric Company (LG&E) is required to maintain and operate the Cane Run Generating Station in a manner consistent with good air pollution control practices for minimizing emissions, as defined in KRS Chapter 77 Air Pollution Control.

The purpose of this plan is to identify and commit to “reasonable precaution” control measures that will minimize fugitive particulate emissions, control objectionable odors that may originate on plant property, and prevent unnecessary emissions. This plan has been developed at the request of the Louisville Metro Air Pollution Control District (APCD).

Louisville Metro

Air Pollution Control District 850 Barret Ave.

Louisville, KY 40204-1745

502-574-6000

Introduction

This plan identifies potential sources of fugitive particulate emissions and potential objectionable odors from equipment and processes at LG&E’s Cane Run Generating Station, 5252 Cane Run Road. The plan also identifies measures to further control potential dust from these sources. The sources identified by the District include: the Unit 4/5 Sludge Processing Plant (SPP), the landfill, various ash ponds and ditches, 4/5 Fly Ash transfer Line, maintenance procedures associated with the generating unit stacks, construction activities and other sources of fugitive dust (piles, roads, yards). This plan is divided into four sections:

Site Description
Description of sources of potential fugitive particulate emissions and objectionable odors
Control measures to minimize fugitive particulate emissions and objectionable odors
Primary Contact List

Section 1 – Site Description

LG&E’s Cane Run Generating Station (Cane Run) is located in southwestern Louisville at 5252 Cane Run Road. Cane Run generates electric energy for local and remote distribution. Coal is the primary fuel used to fire three (3) commercial boilers for generation of electricity via steam turbines and generators. Waste solids from the Flue Gas Desulfurization systems are mixed with fly ash and fixation lime, and the resulting inert lightweight concrete material is placed in an on- site landfill.

The Cane Run site consists of 510 acres with river frontage on the Ohio River. The existing operation is spread throughout the acreage. Coal is delivered by rail car with shipments placed in a storage pile.

The parking areas are asphalt surfaced and located in several areas on the site, including the parking area directly beside the security gate/office for use by contractors and employees.

The aerial map below highlights the various potential sources and areas of concern that are discussed within this plan.

Cane Run Aerial Site Map

Section 2 – Description of Potential Sources of Dust or Odor at Cane Run Generating Station

Potential Sources:

Unit 4/5 SPP
Landfill
Unpaved Roads
Fly Ash Transfer Line
Unit 4, 5, and 6 Stacks Maintenance Activities
Ash Pond, E-Pond, South Basin and Ditches
Storage yards and piles
Paved Roads
Construction Activities

Unit 4/5 SPP

The Unit 4/5 SPP is located on the southwest side of the plant site, in front of the landfill. The 4/5 SPP receives transported fly ash via a blower system, which includes a transfer line from a central bin where fly ash has been collected from hoppers located around each of the three coal- fired boilers. The fly ash is mixed with de-watered scrubber sludge to create a physically and environmentally stable product that is stored onsite in the plant¡¦s landfill.

The 4/5 SPP pug mill mixer incorporates a wet cyclone dust collector and a HEPA filtering system contained within the 4/5 SPP building.

During maintenance activities or general operation, on an as-needed basis, a roof vent may be utilized for ventilation.

Potential Fugitive Dust Sources from the 4/5 SPP include:

Conveyor
Stacker Pad
Fly Ash Silo Safety Valve
Fixation Lime Silo Safety Valve
Building Roof Vents

Potential Point Source for Dust Emissions from the 4/5 SPP Include:

Fly Ash Silo Baghouse Vent
Fixation Lime Silo Baghouse Vent

Material Storage

The material storage yard is located in the middle of the property near the ash pond and consists of a stockpile of bituminous coal. Coal is delivered by railcar and transferred to an onsite stockpile. Under normal operation, the facility may incur up to 100 truck trips per weekday divided between trucks delivering raw materials for production and large off road dump trucks hauling Poz-o-tec to be placed in the landfill. Raw powdered bulk materials (lime, soda ash, and fly ash) used in the production of power is delivered to the site by pneumatic tanker trailer and the materials are blown into silos which all have bag-houses to mitigate dust during transfer activity.

Potential fugitive dust from material storage includes:

Material transfer from trucks
Wind erosion from coal stockpile
Silo Safety Valves

Landfill

The Cane Run landfill contains Poz-o-tec which is an inert, lightweight concrete that is made by mixing FGD solids (calcium sulfite, and sulfate), fly ash, and fixation lime. An excavator is used

at the SPP stacker pads to load Poz-o-tec into the dump trucks which are placed in the landfill.

Potential fugitive dust from the landfill may be caused by:

Wind erosion.
Heavy equipment performing excavation on contours and slopes within active areas.
Mechanical traffic on haul roads.
Surface Integrity

Federal Highway Administration (FHWA) has conducted extensive research concerning pozzolan materials (fly ash, Poz-o-tec, etc.) in use as roadway base material and slope stabilizers. Data indicates that material with higher fly ash content such as Poz-o-tec has less moisture infiltration than standard concrete and has a structure that provides a denser product that allows fewer voids between particles. This would indicate that freeze-thaw erosion potential is negligible and would not be a source of fugitive emissions from the landfill. Data previously submitted to APCD shows that the density of Poz-o-tec is similar to that of Kentucky clay soils. This landfill was engineered to meet continuous compliance with Kentucky Division Waste Management structural requirements and measurements.

Unpaved Roads

Unpaved roads at the Cane Run site are typically graveled at #57 grade. The ash pond roads have been sealed as a dust control measure and traffic is limited. Vehicle access to unpaved roads is limited to contractors and employees performing required operational duties.

Potential fugitive dust from unpaved roads may be caused by:

Dry road conditions
Wind erosion
Vehicle traffic
Material fallout from vehicle traffic

Paved Roads

The paved roads are asphalt or concrete surfaced and traffic is limited to contractors and employees.

Potential fugitive dust from paved roads may include:

Material tracked from unpaved surfaces onto paved roads by vehicle traffic
Material fallout from vehicle traffic

Fly Ash Transfer Line

Due to a recent dust event that resulted from a crack that developed in the fly ash transfer line, LG&E performed an eight year look back of its past maintenance records and was unable to find any other incidents of this nature for this equipment. The majority of the transfer line is located below ground and the section of pipe that cracked was above ground at an “elbow joint”.

Potential fugitive dust from fly ash transfer line may include:

Failure of pipe section

Unit 4, 5, and 6 Stack Maintenance Activities

Typically once or twice per year each of the generating units is off-line to perform scheduled routine maintenance, which includes balancing fans. In addition, it may be necessary to balance fans more often if vibration issues arise. In order to balance the fans, they must be operating. During balancing, residual fly ash can be dislodged and picked up by the draft and exit the stack. Potential emissions from maintenance activities may include:

Fan balancing

Ash Pond, E-Pond, South Basin and East Ditch

Due to the build-up of bacteria, odors may result when cleaning materials from inactive areas of the ponds and east ditch. The drainage ditch south of the 4/5 SPP no longer exists due to the construction of the MSE wall, thus it is has been removed from this plan.

Potential objectionable odors from ponds and ditches may include:

Ash Pond
East Ditch
E-Pond
South Basin

Construction Activities

A new natural gas combined cycle (NGCC) electricity generating facility will be constructed adjacent to the existing Cane Run Generating Station. Construction activities will take place until the completion of the new plant. Potential dust emissions from construction activities can vary significantly, depending on the level/type of activity and weather conditions.

Potential fugitive dust from construction activities may include:

Material hauling
Excavating
Construction traffic

Section 3 – Control Measures to Minimize Emissions Site Monitoring

The Production Supervisor of Compliance and / or the Production Leader will be on-site

during hauling and placement activities and will assess the need for dust control on a continuing basis.

A water truck(s) will be employed during all hauling and placement activities.
In the event dry weather persists, the frequency of watering will be adjusted to control fugitive dust emissions.
If it is determined that weather conditions have contributed to the control of fugitive dust emissions, watering operations may be suspended until such time as it appears necessary for the control of fugitive dust emissions.
Watering will be suspended when ambient air temperatures are below freezing or if ice is present.
To assist with monitoring the condition of the plant¡¦s roadways and open areas, video cameras were added throughout plant property. Real-time displays are monitored in the control rooms using video surveillance software which provides the feed of video surveillance of the plant property. The recording frequency of these cameras is on a continuous basis and video is archived on the company¡¦s network drive. The software allows multiple independent cameras to be viewed under a single monitor, allowing flexibility to the user to monitor and adhere accordingly to daily job duties as they are assigned. In the event that fugitive dust is observed, the operator will take corrective action which may include shutting down the process, initiating control measures, or notifying the appropriate personnel, all within a reasonable timeframe to mitigate fugitive dust emissions. Daily review of video footage is performed in addition to real-time monitoring to reaffirm fugitive dust controls were operating properly and that dust did not leave the property. Video footage will be maintained in accordance with LG&E¡¦s record retention policy.
Documentation of site monitoring activities will be kept on file.

Unit 4/5 SPP

The mixer dust collector emission point source discharge from the roof of the building has been eliminated. The mixer dust collector now discharges into the SPP building through a HEPA filter system.
The east side of the 4/5 SPP has a wind break screen installed to help control fugitive dust from the 4/5 SPP stacker pad.
The ventilation from the #3 or west most roof vent is now ducted to a new two stage filter system located outside the building at ground level. Under typical operation of the outside filter, there is zero to minimal dust emissions. The filter system has a rating of MERV 15. The filters will be changed as needed per indication from a differential pressure reading. Under normal operating conditions, all three vent fans can be used for building ventilation. In the event of a dust-related incident within the building, all three vent fans are automatically closed off. The #3 vent fan can then be turned back on to ventilate the building in a controlled manner utilizing the two-stage discharge filter.
The plant has adopted and implemented a SOP which addresses roof vent operation. A copy of this standard operating procedure is attached to this compliance plan.
On-screen logic control has been added to monitor the status of the vent fans and to operate the on/off function of the vent fans to provide more efficient and expedient control.
Additional water spray nozzles were added at exit of conveyor from the building and the top of the 4/5 SPP stacker conveyor.
Controls and new actuated valves for the spray water nozzles located at the mixer discharge conveyor and top of the stacker conveyor were added and can be operated from the SPP control room.
New logic was installed to shut the fly ash gate if the filter cake drops below 7 tons/hr. Filter cake scales A & B were also recalibrated and the vat level controller was tuned.
A new programmable logic controller (PLC) based control system was installed at the Cane Run 4&5 Sludge Processing Plant (SPP) on November 19, 2012 and is fully operational. The new control system replaced existing hardwired controls and consisted of a new Allen Bradley Controllogix PLC, dual touchscreen operator displays, and two

(2) smart transmitters. The project scope included the purchase, removal, and installation of control system. The major objective of this project is that once an off-normal condition occurs at the 4&5 SPP, process controls will immediately shut down the process, turn on water spray systems, and inform operators so that measures can be taken to further mitigate any potential dusting or other unfavorable event.

Visible emission surveys of Unit 4/5 SPP will be conducted hourly, and corrective action will be taken when necessary. Documentation will be kept on file and submitted to the District upon request. A copy of the recordkeeping form is attached to this compliance plan.

Hauling and Storage of Materials

Transfer of materials is suspended if the truck’s conveying equipment is not in proper working condition.
Material transfer conveyors are permitted emission points and will be operated in accordance with the facility’s Title V operating permit.
Bulk materials stored in silos (fly ash, fixation lime, soda ash) are stored dry and not exposed to the atmosphere and should not generate fugitive dust under normal conditions. Storage silos are permitted emission points equipped with either a bin vent or baghouse that is intrinsic to process.
Coal piles will continue to be maintained to prevent fugitive dust emissions. Coal is brought on-site in lump form and transferred by covered conveyor to coal crushers. Coal crushing occurs in an enclosed area and all emissions are through a permitted emission point.
Storage piles will continue to be maintained to prevent fugitive dust emissions.
Mitigation procedures may include wetting of the material or covering of the trucks, to prevent fugitive emissions from trucks hauling dry material likely to become airborne.

Landfill

In accordance with the Air Pollution Control Board Agreement No. 12-01, LG&E submitted a plan for the application of dust suppressant to inactive open areas of the landfill at the Cane Run Generating Station. Dust suppressant will be applied based upon the following guidelines outlined in the Dust Suppressant Application Plan(also attached):
- Application will follow the manufacturer¡¦s specifications or other tested and approved procedures.
- The application shall be limited to inactive open areas of the landfill or other areas that are noted to show signs of degradation.
- The application rate will be carefully monitored to ensure there is adequate coverage without pooling or runoff of products.
- The amount of dust suppressant applied should not exceed the minimum amount required to effectively suppress dust.
- Ensure that dust suppressants do not enter and contaminate water bodies, including surface water and groundwater. Do not allow the product to leave the designated areas.
- Do not apply products if precipitation is occurring, or forecast to occur before the product sets or cures.
Testing of multiple dust suppressants was completed on designated areas of the Cane Run landfill and Gorilla-Snot® was selected as the dust suppressant that will be utilized. If the need arises, the use of similar products from other manufacturers may be used. The material was tested at 11 parts water to one part dust suppressant and based upon on-site testing, the application is expected to last 6-12 months. The dust suppressant is applied according to the manufacturer¡¦s recommendation to inactive open areas of the landfill and reapplication will occur on an as needed basis. The applied areas will be inspected weekly for signs that the dust binder is degrading. Reapplication and application to additional areas will occur when the areas are noted to show signs of degradation, which may include:
- Visible dusting from wind erosion off the landfill
- Evidence of erosion in the area during rain events
Prior to any additional dust suppressant testing, information shall be submitted to APCD.
According to APCD Regulation 1.14, Sections 2.1.4, covering of open bodied trucks is necessary when material being transported is likely to become airborne. The material being hauled, Poz-o-tec, is not likely to become airborne during transportation. Due to the moisture content (20-25%) that is characterized with Poz-o-tec a control measure is already employed within the process. Off-road open bodied trucks, by design, are not equipped with covers.
Mitigation procedures may include wetting of the material or covering of the trucks, to prevent fugitive emissions from trucks hauling dry material likely to become airborne.
The landfill operator depot was relocated away from Cane Run Road to the north end of the landfill and the road to the back gate will be closed.

LG&E had previously proposed an installation of a fabric cover on the face of the steep slope behind the SPP. During the course of this evaluation, it was determined that the application of a fabric covering on the face of this slope is not the most viable option. In addition, a process of “hydro-mulching” was also considered. Hydro mulching is the process of applying moist mulch that contains seeds and tacking agents intended to adhere to the surface on which it is applied. However, with consideration of limitations during growing seasons and the proven effectiveness

of the application of dust suppressant (Gorilla-Snot®), the plant will manage sloped areas through application of the dust suppressant.

Unpaved Roads

To date, there are nine (9) speed limit signs that are posted along the roadway entering the plant and throughout the plant. Signage states that all vehicular traffic on haul roads and site roads are restricted to 15 mph. Vehicular traffic will be advised to lower its off- road speed, based on off-road conditions due to weather, to a speed that generates minimal dust.
Cane Run utilizes a water truck to keep the roadways, entrance and exit areas within the site wet in order to control dust. An additional water truck is on site as a backup or if needed to assist with watering efforts during hot/windy weather.
The plant increased operating hours of the water truck to run continuously every weekday 12 hours per day during the summer, but may be extended by the Production Supervisor of Compliance or designee if weather conditions justified watering of unpaved roads. Weekend operation will be planned on an as-needed basis, based on weather forecast. An additional water truck is on site and available if needed, as determined by the landfill manager (or designee in his absence). The watering process will occur continuously during hours of landfill operation in dry conditions.
The plant has posted a guard at the South gate near the 4/5 SPP to restrict unnecessary traffic to limit the potential for debris being deposited on a public road. In addition, a wheel wash station has been installed and utilized as needed in support of this effort.
Dust awareness guidelines will be provided to applicable contractors. Attached is a copy of these guidelines.
Unnecessary travel on these routes will be restricted by placing warning signs to discourage vehicle trespassing and controlling access to the site.
Vegetation will be cleared only from those areas where work will occur immediately.
Gravel, only as needed, will be applied to road surfaces to reduce dust emissions.

Paved Roads

All passenger vehicles, including employee vehicles entering and leaving the facility, will be limited to paved roads and parking lots to prevent the generation of dust, unless required for direct performance of operational duties. Should operational duties cause dust to transfer to paved roads, the material will be cleaned. Designated plant personnel will water down the area and then by hand sweep up the material.
Roads will be maintained in such a manner as to prevent the tracking of debris onto any public road.
A wheel wash is not needed due the exceptional length of the paved road from the plant’s entrance to public roads.

Fly Ash Transfer Line

Although historically it has not been an issue, the plant has taken additional measures to mitigate the possibility of a future occurrence.
A thorough inspection was performed on all above ground sections of the fly ash transfer line. Sectional replacement components were installed from 4/17/2012 – 6/20/2012.
The sections of pipe above ground have been wrapped with insulation to not only protect it from weathering, but additionally to act as a secondary containment should a crack occur in the future. This project began on 5/02/2012 and was completed on 7/31/2012.
To further ensure continuous compliance, the length of pipe above ground will be visually inspected weekly. A log of the visual inspections will be maintained.

Unit 4, 5, and 6 Stack Maintenance Activities

Cane Run has developed a fan balance procedure that includes ensuring the full FGD system is in service, monitoring the stacks with newly installed video cameras, and having the fans ramped up slowly to minimize dust entrainment. Fan balancing occurred four times in 2010, three times in 2011, and three times in 2012 prior to implementation of the fan balancing procedures.

Fan balancing is a maintenance activity, and requirements relative to startup, shutdown, or upset conditions are not applicable.
For fan balancing events that are known or planned ahead of time, a one (1) day notification will be given to APCD by normal notification means. For all other fan balancing events, notification will be provided to APCD as soon as the decision has been made to balance the fan.

Odor Control of Ash Pond, E-Pond, South Basin and East Ditch

Cane Run is in the process of eliminating the E-pond as a settlement control and will construct a South Basin located approximately north of the current E-Pond. The South Basin will provide settlement control for the Ash Pond closure site and landfill runoff and move the potential source of odor farther from the neighborhood. Once the landfill is closed, the East Ditch will no longer be a source for landfill runoff thus eliminating the potential for odors. During the process of closing the ash pond, Cane Run will perform the following measures to control odor from the site.

Contractors will notify the Production Supervisor of Compliance or designee 24 hours in advance when any digging is to occur in the East Ditch, E-Pond, South Basin and inactive areas of the ash pond. These ponds will be cleaned as needed, typically once a month.
A courtesy call will be made to APCD on days that cleaning activity will take place in any of the areas referenced above as well as pro-active communication of these activities to the neighborhood. During cleaning activity, personnel will monitor surrounding areas for any objectionable odor and temporarily cease cleaning activity if the wind blows toward the neighborhood.
On a case-by-case basis, and in compliance with Cane Run’s land and water permits, the plant will use chlorination as a supplemental odor control procedure when cleaning the East Ditch or the drainage ditch south of the 4/5 SPP stacker pad. At this time, the South Ditch is nearly 100 percent full and will not be utilized for drainage in the near future. The East Ditch is typically unutilized and dry; however, in both ditches, while cleaning activities are occurring, chlorination will be used as needed based on determination by the Production Supervisor of Compliance or designee. The Production Supervisor of Compliance or designee will notify APCD when plant personnel detect off-site objectionable odors and will notify APCD when any changes are made to the ponds or ditches that may cause off-site objectionable odors.
The pH levels of the ponds are monitored and maintained in accordance with the existing KPDES permit.
During construction activity, daily meetings are held Monday through Friday between the Plant Production Supervisor of Compliance and the Project Lead to discuss the work plan for the next 3 days to ensure any potentially odor causing activity is known. Any concerns discussed during the meeting are communicated to the individuals supervising the project work as needed for mitigation. In addition, the Plant Production Supervisor of compliance conducts a weekly meeting with project personnel to ensure any changes to the controls are known and that all upcoming work is reviewed from a dust/odor risk perspective.

The previous measures have successfully mitigated the potential for objectionable odor as a result of plant operations. However, the scale of construction work at the plant presents a higher potential for this issue and therefore, the plant has commenced analysis of the following options to further reduce said potential. Implementation of one or more of these options (along with the previously discussed measures) will reduce these odors from objectionable to de minimis.

Lime Slurry – This material utilized in FGD operation has a pH of greater than 9 sufficient to control odor causing bacteria and is readily available.
Hydrogen Peroxide – an oxidizer that is effective in controlling sulfide and organic related odors in wastewater. It decomposes to oxygen and water which adds dissolved oxygen to the system and reduces Biological Oxygen Demand.
Nalco product – Information is being acquired from a representative for products that are effective in controlling odors.

Construction Activities

To minimize material track-out and transfer onto paved roads vehicles will be cleaned periodically to reduce the accumulation of material.
Watering of roadways will be done on an as-needed basis.
Mitigation procedures may include wetting of the material or covering of the trucks, to prevent fugitive emissions from trucks hauling dry material likely to become airborne.
Watering will be used during any of the following construction activities:
- Road cutting, replacement, etc.
- Digging and/or excavating site property
- Storage piles
The contractor, Bluegrass Power Constructors, has also implemented measures within its construction storm water pollution prevention plan for reducing potential dust emissions from construction activities. The following measures are outlined:
- Water sprays, placing aggregate or shell rock, wind fencing, and physical or vegetative stabilization practices will be used for dust control as appropriate.
- The vehicle tracking of sediment will be reduced by installing stabilized construction road entrances. If necessary, vehicles will be cleaned to remove excess mud, dirt, or rock prior to exiting from the construction site.
- The main plant entrance road shall be street swept from the point of access to CR7 to Cane Run Road, as needed.
- A wheel wash will be used as-needed.
- All waste materials generated during construction will be collected and stored in labeled metal or plastic dumpsters and removed from the construction site by a licensed waste management contractor.

Additional Measures

LG&E Cane Run Plant Manager will notify the District of any additional procedures that are implemented and will submit a revised dust control plan to reflect any new procedures.

The Plant Manager is responsible for implementing the procedures outlined in the dust control plan. The plan will be maintained on file at the Cane Run Generating Station for plant personnel to use and has been submitted to APCD for approval.

Plant Manager: David Tummonds

Option 2: Submit a guarantee with signature from the control device manufacture stating the control device efficiency.

Option 3: Perform stack test. See Note 3 for general testing requirements.

Until the District receives a guarantee with signature from the control device manufacturer stating the control device efficiency is higher (Option 2), or an approved stack test (Option 3), the pre-approved efficiency (Option 1) will be used in all calculations to demonstrate compliance with applicable standards and calculations for emission inventory.

General Testing Requirements (Regulation 2.16, section 4.1.9.1)

Plant-wide the owner or operator shall retest all control devices within ten (10) years since the most recent District accepted performance test or within 180 days after the effective date of the permit if no previous test has been performed. For equipment which has been tested but not within ten years prior to the effective date of this permit the Company may submit within 90 days of the effective date of this permit, contingent on approval by the District, a schedule which shall at a minimum propose testing for all affected equipment within this permit cycle. Thereafter the Company shall retest each affected device at least once every 10 years. Devices of adequately similar design and filter media may be represented by a common performance test contingent upon review and approval by the District of the testing protocol. In lieu of the control efficiency testing, unless required by a Federal Regulation, the owner or operator may submit a signature guarantee from the control device manufacture stating the control device efficiency.

The owner or operator shall construct all equipment in such a manner that the following testing requirements can be performed.

The owner or operator shall perform an EPA Reference Method (or equivalent methods that approved by the District) performance test. The test shall be performed at 90% or higher of maximum capacity, or allowable/permitted capacity, or at a level of capacity which results in the greatest emissions and is representative of the operations. Failure to perform the test, at maximum capacity, allowable/permitted capacity, or at a level of capacity which resulted in the greatest emissions, may necessitate a re-test or necessitate a revision of the allowable/permitted capacity of the process equipment depending upon the difference between the testing results and the limit.

The owner or operator shall perform a capture efficiency test using EPA guidelines. In lieu of performing a capture efficiency test, the owner or operator may submit a reasonable estimate of capture efficiency with thorough justification subject to approval by the District.

The owner or operator shall submit written compliance test plans (protocol) for the control efficiency and capture efficiency. They shall include the EPA test methods that will be used for compliance testing, the process operating parameters that will be monitored during the performance test, and the control device performance indicators (e.g. pressure drop, minimum combustion chamber temperature) that will be monitored during the performance test. The compliance test plans shall be furnished to the District at least 30 days prior to the actual date of the performance test. Attached to the permit is a Protocol Checklist for Performance Test for the information to be submitted in the protocol.

The owner or operator shall be responsible for obtaining and analyzing audit samples when the EPA Reference Method is used to analyze samples to demonstrate compliance with the source’s emission regulation. The audit samples shall be available for verification by the District during the onsite testing.

The owner or operator shall provide the District at least 10 days prior notice of any performance test to afford the District the opportunity to have an observer present.

The owner or operator shall furnish the District with a written report of the results of the performance test within 60 days following the actual date of completion of the performance test.

The owner or operator shall provide written notification to the District of the actual date of initial startup (only required for new equipment). The written notification shall be postmarked within 15 days after the effective date of the permit.
