RELEASED TO: Fort Lupton Press on PUBLISHED: September 18, 2010 September 14, 2010 COLORADO DEPARTMENT OF PUBLIC HEALTH AND ENVIRONMENT AIR POLLUTION CONTROL DIVISION OPERATING PERMIT RENEWAL SUMMARY PERMIT NUMBER: 95OPWE096 AIRS ID#: 1230250 DATE: September 14, 2010 APPLICANT: Thermo Cogeneration Partnership, L. P., A Delaware Limited Partnership—Thermo Cogeneration Facility REVIEW ENGINEER: Jacqueline Joyce SOURCE DESCRIPTION Thermo Cogeneration Partnership, L. P. has applied for renewal of their Operating Permit issued for the Ft. Lupton Cogeneration facility located at 6811 Weld County Road 31 in Ft. Lupton, Colorado in Weld County. This facility consists of five combustion turbines and associated duct burners, which are used to generate steam and produce electricity for sale and is classified under SIC 4911. This facility is located in an area classified as attainment for all pollutants except ozone. It is classified as non-attainment for ozone and is part of the 8-hr Ozone Control Area as defined in Regulation No. 7, Section II.A.1. This source is a major stationary source with respect to Prevention of Significant Deterioration (PSD) review and non-attainment area new source review(NANSR) requirements. There are no affected states within 50 miles of this facility. Rocky Mountain National Park, a Federal Class I designated area, is within 100 km of this facility. This source is not subject to the Accidental Release provisions of section 112(r) of the Federal Clean Air Act. In addition, although the combustion turbines are equipped with steam injection to control NOx emissions they are exempt from the compliance assurance monitoring (CAM) requirements in 40 CFR Part 64 because at the time the CAM plan was required the Title V permit specified a continuous compliance determination method (§ 64.2(b)(1)(vi)).

Permitted emissions that were below the de minimis level (2 tons/yr) were not included in the original Title V permit and the subsequent renewal permit. 3 V0C emissions are based on an emission factor of 0.0527 lb/mmgal for chloroform. Since V0C emissions are below the APEN de minimis level (2 tons/yr), the V0C emission limit is not included in the permit. EMISSION SOURCES The following discussion identifies the changes that were made in the renewal permit. Emergency Generator and Emergency Fire Pump Engine-These engines will be subject to work practice requirements in 40 CFR Part 63 Subpart Z777 (National Performance Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines) beginning May 3, 2010. The appropriate applicable requirements from 40 CFR Part 63 Subpart Z777 have been included in the permit. ALTERNATIVE OPERATING SCENARIOS Minor language change was made to the first paragraph under Condition 2 of the Alternative Operating Scenario. INSIGNIFICANT ACTIVITY LIST No changes were made to the insignificant activity list. PERMIT SHIELD No additional non-applicable requirements were included in the permit shield. f TECHNICAL REVIEW DOCUMENT For RENEWAL of OPERATING PERMIT 95OPWE096 Thermo Cogeneration Partnership, L. P., a Delaware Limited Partnership Ft. Lupton Cogeneration Facility Weld County Source ID 1230250 Prepared by Jacqueline Joyce June 2010 Revised September 2010 I. Purpose: This document will establish the basis for decisions made regarding the applicable requirements, emission factors, monitoring plan and compliance status of emission units covered by the renewed operating permit proposed for this site. The current Operating Permit was issued October 1, 2006. The expiration date for the permit is October 1, 2011. This document is designed for reference during the review of the proposed permit by the EPA, the public, and other interested parties. The conclusions made in this report are based on information provided in the renewal application submitted May 17, 2010, comments on the draft permit and technical review document received September 8, 2010 via e-mail, previous inspection reports and various e-mail correspondence, as well as telephone conversations with the applicant. Please note that copies of the Technical Review Document for the original permit and any Technical Review Documents associated with subsequent modifications of the original Operating Permit may be found in the Division files as well as on the Division website at http://www.cdphe.state.co.us/apiTitlev.html. Any revisions made to the underlying construction permits associated with this facility made in conjunction with the processing of this operating permit application have been reviewed in accordance with the requirements of Regulation No. 3, Part B, Construction Permits, and have been found to meet all applicable substantive and procedural requirements. This operating permit incorporates and shall be considered to be a combined construction/operating permit for any such revision, and the permittee shall be allowed to operate under the revised conditions upon issuance of this operating permit without applying for a revision to this permit or for an additional or revised construction permit. II. Description of Source This facility consists of a cogeneration facility defined under Standard Industrial Classification 4931. Electricity for sale is produced by five (5) combustion turbines, equipped with duct burners. Each combustion turbine serves a generator rated at 57.412 MW (name-plate). Exhaust gas from the combustion turbine, which may be Page 1 heated further by duct burners, is used to either generate electricity or to heat a nearby tomato greenhouse. There are two steam turbines, each rated at 52.220 MW (name- plate). Other significant emission units at the facility are a cooling tower, emergency back-up generator and fire pump. The facility is located in Weld County at 6811 Weld County Road 31, in Ft. Lupton, CO. This facility is located in an area classified as attainment for all pollutants except ozone. It is classified as non-attainment for ozone and is part of the 8-hr Ozone Control Area as defined in Regulation No. 7, Section II.A.1. There are no affected states within 50 miles of the facility. Rocky Mountain National Park, a federal Class I area is within 100 km of this facility. Based on the information provided in the renewal application, no changes have been made to any of the significant emission units. The summary of emissions that was presented in the Technical Review Document (TRD) for the renewal permit has been reproduced here. Since there have been no changes to permitted emission and/or fuel consumption limitations and no new emission units have been added to the facility, the potential to emit (PTE) has not changed. Both potential and actual emissions (in tons per year) at the facility are as follows: Potential to Emit(tons/yr) Emission Unit PM PM10 SO2 NO; CO VOC HAPS _ Turbine/Duct 16.81 16.81 2 90.51 9.64 See Burner 1 (S001) Table on Turbine/Duct 16.81 16.81 2 589. 90.51 9.64 Page 7 Burner 2 (S002) Turbine/Duct 16.81 16.81 2 90.51 9.64 Burner 3 (S003) Turbine/Duct 16.81 16.81 2 90.51 9.64 Burner 4 (S004) Turbine/Duct 16.81 16.81 2 90.51 9.64 Burner 5 (5005) Emergency Gen. 0.27 0.26 0.59 3.81 1.49 0.26 (S006)2 Fire-Pump 0.07 0.07 0.14 1.52 0.25 0.07 (S007)2 Cooling Tower 9.5 9.5 1.23 (S011) Total 93.89 93.88 10.73 594.33 454.29 49.76 1O55 'Each turbine/duct burner has individual NOx limits, however, the total NOx limits for all units is more restrictive, so the total limit is shown in the table. 2Emissions shown are from the original construction permits. Permitted emissions that were below the de minimis level (2 tons/yr) were not included in the original Title V permit and the subsequent renewal permit. Page 2 I 3 VOC emissions are based on an emission factor of 0.0527 lb/mmgal for chloroform. Since VOC emissions are below the APEN de minimis level (2 tons/yr), the VOC emission limit is not included in the permit. The criteria pollutant PTE shown above is based on permitted emission limits for the turbines, duct burners, engines and cooling tower. The breakdown of HAP emissions by emission unit and individual HAP is provided on page 7 of this document. The PTE of HAP emissions is based on AP-42 emission factors, permitted fuel consumption limits and heat values of 1020 Btu/SCF for natural gas and 137,000 Btu/gal for diesel fuel.

MACT Requirements Although the facility is not a major source for HAPS, the EPA has been promulgating rules for area sources (sources that are not major), those requirements that could potentially apply to this facility are discussed below: Paint Stripping and Miscellaneous Surface Coating at Area Sources (40 CFR Part 63 Subpart HHHHHH) The final rules for paint stripping and miscellaneous surface coating were published in the Federal Register on January 9, 2008 and apply to area sources that perform paint stripping operations using methylene chloride, spray application of coatings to motor vehicles and mobile equipment and spray application of coatings that contain the target Page 3 HAPS (chromium, lead, manganese, nickel or cadmium). As indicated in 40 CFR Part 63 § 63.11170(a)(2) and (3), spray applications (to motor vehicles and using coatings that contain the target HAPS) that meet the definition of facility maintenance are not subject to the requirements in this rule. The Division considers that any spray coatings of motor vehicles and mobile equipment and spray application of coatings that contain the target HAP at this facility would meet the definition of facility maintenance. The source indicated that none of the paint stripping chemicals used at the facility contain methylene chloride; therefore, the provisions in 40 CFR Part 63 Subpart HHHHHH do not apply. Reciprocating Internal Combustion Engines (RICE) (40 CFR Part 63 Subpart ZZZZ) Final revisions to the RICE MACT were published in the Federal Register on March 3, 2010 and these revisions address existing (commenced construction prior to June 12, 2006) compression ignition engines at area sources. There are diesel-fired engines driving an emergency generator and fire pump included in Section II of the permit. Both engines are considered emergency engines. According to the current permit, these engines commenced operation in May 1994, so they are existing engines and are subject to requirements in MACT ZZZZ. Since these engines are considered emergency engines they are subject to management standards (oil and filter change and inspect air cleaners, hoses and belts). The source is required to comply with these requirements by May 3, 2013. The appropriate applicable requirements will be included in the renewal permit. Compliance Assurance Monitoring (CAM) Applicability CAM was reviewed for this facility during the first renewal (issued October 1, 2006). At that time it was determined that CAM did not apply to the turbines, since the Title V permit specified a continuous monitoring method for NOx (per 40 CFR Part 64 § 64.2(b)(1)(vi)) and there were no other emission units equipped with a control device. Since there have been no physical changes to the existing emissions units and no new units added since the first renewal, there is no change to the CAM applicability at this facility. III. Discussion of Modifications Made Source Requested Modifications The source submitted their renewal application on May 17, 2010. In their renewal application, the source did not request any changes to their permit. Other Modifications In addition to the modifications requested by the source, the Division has included changes to make the permit more consistent with recently issued permits, include comments made by EPA on other Operating Permits, as well as correct errors or Page 4 omissions identified during inspections and/or discrepancies identified during review of this renewal. The Division has made the following revisions, based on recent internal permit processing decisions and EPA comments, to the Thermo Ft. Lupton Cogeneration Facility Renewal Operating Permit with the source's requested modifications. These changes are as follows: Page Following Cover Page • The monitoring and compliance periods and report and certification due dates are shown as examples. The appropriate monitoring and compliance periods and report and certification due dates will be filled in after permit issuance and will be based on permit issuance date. Note that the source may request to keep the same monitoring and compliance periods and report and certification due dates as were provided in the original permit. However, it should be noted that with this option, depending on the permit issuance date, the first monitoring period and compliance period may be short (i.e. less than 6 months and less than 1 year). Section l — General Activities and Summary • Changed the citation for the definition of 8-hour ozone control area in Condition 1.1. • Condition 2 (alternative operating scenario for turbine replacement) was revised to clarify that only temporary turbine replacement is allowed (the phrase "and permanent" was removed from the first line in the first paragraph under Condition 2). Section 11.2 — Emergency Generator • Added the appropriate 40 CFR Part 63 Subpart ZZZZ requirements — management practices (oil and filter change, inspect air cleaner and inspect hoses and belts). Note that the Subpart ZZZZ requirements are included in "new" Section 11.6. • Added the appropriate 40 CFR Part 63 Subpart A requirements Since this engine is not subject to any emission limitations, monitoring requirements, notification and reporting requirements the requirements in §§ 63.7. 63.8, 63.9 and 63.10 do not apply. In addition, since this emission unit is an existing unit the requirements in § 63.5 (preconstruction review and notification requirements) do not apply. Finally, Table 8 of Subpart ZZZZ indicates that operation and maintenance requirements in 63.6(e) do not apply. Therefore, the permit will only include the prohibition and circumvention requirements in § 63.4. Page 5 Section 11.3 — Diesel Fired Emergency Fire Pump • Corrected the references to other condition numbers in Conditions 3.4.1 and 3.4.5. • Added the appropriate 40 CFR Part 63 Subpart ZZZZ requirements — management practices (oil and filter change, inspect air cleaner and inspect hoses and belts). Note that the Subpart ZZZZ requirements are included in "new" Section 11.6. • Added the appropriate 40 CFR Part 63 Subpart A requirements As indicated above for the emergency generator, only the prohibition and circumvention requirements in § 63.4 will be included in the permit. Section III —Acid Rain Requirements • Revised the table in Section 2 to include calendar years corresponding to the relevant permit term for the renewal. Section V— General Conditions • Revised the version date. • Labeled the 3rd paragraph of General Condition 29.a as 29.b and added the provisions in Reg 7, Section III.C as paragraph e. Appendices • Corrected minor typos in the tables in Appendices B and C Page 6 r) co O O a 0 N W W N N O- N V Ow,, o 0 F 0 o Co) V CO C O O O 5.U W W W a n o 0 O CO 0 0 6 N n Cl E co CO O 9 E 9 w w o n en a r M cor E W O O W U R (0 0 co 16 0 N N W C CO N O O.

Alternative Operating Scenarios (10/1/05 version) The following Alternative Operating Scenario (AOS) for temporary combustion turbine replacement and turbine component replacement has been reviewed in accordance with the requirements of Regulation No. 3., Part A, Section IV.A, Operational Flexibility-Alternative Operating Scenarios, and Regulation No. 3, Part B, Construction Permits, and Regulation No. 3, Part D, Major Stationary Source Non- Attainment Area New Source Review and Prevention of Significant Deterioration (NANSR) and has been found to meet all applicable substantive and procedural requirements. This permit incorporates and shall be considered a Construction Permit for any combustion turbine replacement performed in accordance with this AOS, and the permittee shall be allowed to perform such turbine or turbine component replacement without applying for a revision to this permit or obtaining a new Construction Permit. 2.1 Routine Turbine Component Replacements 2.1.1 The following physical or operational changes to the turbines in this permit are not considered a modification for purposes of NSPS GG, NANSR/PSD, or Regulation No. 3: 2.1.1.1 Replacement of stator blades, turbine nozzles, turbine buckets, fuel nozzles, combustion chambers, seals, and shaft packings, provided that they are of the same design as the original. 2.1.1.2 Changes in the type or grade of fuel used, if the original gas turbine installation, fuel nozzles, etc. were designed for its use. 2.1.1.3 An increase in the hours of operation (unless limited by a permit condition). 2.1.1.4 Variations in operating loads within the turbine design specification. 2.1.1.5 Any physical change constituting routine maintenance, repair or replacement. 2.1.2 Turbines undergoing any of the above changes are subject to all federally applicable and state-only requirements set forth in this permit (including monitoring and record keeping), and shall be subject to any shield afforded by this permit. If replacement of any of the components listed in Conditions 2.1.1.1 or 2.1.1.5 above results in a change in serial number for the turbine, a letter explaining the action as well as a revised APEN and appropriate filing fee shall be submitted to the Division within 30 days of the replacement. 2.1.3 Note that the repair or replacement must be genuinely the same design. Except in accordance with the Alternative Operating Scenario set forth below, the Division does not consider that this allows for the entire replacement (or reconstruction) of an existing turbine with an identical new one or one similar in design or function. Rather, the Division considers the repair or replacements to encompass the repair or Operating Permit Number: 95OPWE096 First Issued: 1/1/99 Renewed: DRAFT • Air Pollution Control Division Thermo Cogeneration Partnership, L.P., A Delaware Limited Partnership Colorado Operating Permit Ft. Lupton Cogeneration Facility Permit # 95OPWE096 Page 3 replacement of components at a turbine with the same (or functionally similar) components. 2.2 Temporary Turbine Replacement The following AOS is incorporated into this permit in order to deal with a turbine breakdown or periodic routine maintenance and repair of an existing onsite turbine that requires the use of a temporary replacement turbine. "Temporary" is defined as in the same service for 270 operating days or less in any 12 month period. The 270 days is the total number of days that the turbine is in operation. If the turbine operates only part of a day, that day counts towards the 270 day total. Note that the compliance demonstrations made as part of this AOS are in addition to any compliance demonstrations required by this permit. 2.2.1 The permittee may temporarily replace an existing permitted turbine provided such replacement turbines are General Electric, Model No. LM6000 combustion turbines without modifying this permit, so long as the emissions from the temporary replacement turbine comply with the emission limitations for the existing permitted turbine as determined below. In the absence of credible evidence to the contrary, data from the continuous emission monitoring systems (CEMS) shall be evidence of enforceable compliance or noncompliance of the replacement turbine with any short-term NOx and CO emissions limitations of the original turbine. For comparison with an annual NOx and CO emissions limit, data from the CEMS shall be used to calculate the actual NOx and CO emissions as set forth in this permit. If the data from the CEMS indicates compliance with both the NOx and CO emission limitations, in the absence of credible evidence to the contrary, the source may certify that the turbine is in compliance with both the NOx and CO emission limitations for the relevant time period. If the CEMS data fails to demonstrate compliance with any of the NOx or CO emission limitations, and in the absence of credible evidence to the contrary, the turbine will be considered to be out of compliance for the relevant time periods(s). All data that indicates noncompliance shall be submitted to the Division within 14 calendar days after the data is collected. 2.2.2 Temporary replacement turbines are subject to all federally applicable and state-only requirements set forth in this permit (including monitoring and record keeping), and shall be subject to any shield afforded by this permit. 2.2.3 The permittee shall maintain a log on-site to contemporaneously record the start and stop date of any temporary turbine replacement, the manufacturer and serial number of the turbine(s) that are temporarily replaced during the term of this permit, and the manufacturer and serial number of the replacement turbine.

Lupton Cogeneration Facility Permit# 95OPWE096 Page 4 2.3 Additional Sources The replacement of an existing turbine with a new turbine is viewed by the Division as the installation of a new emissions unit, not "routine replacement" of an existing unit. The AOS is therefore essentially an advanced construction permit review. The AOS cannot be used for additional new emission points for any site; a turbine that is being installed as an entirely new emission point and not as part of an AOS-approved replacement of an existing onsite turbine has to go through the appropriate Construction/Operating permitting process prior to installation. 3. Nonattainment Area New Source Review (NANSR) and Prevention of Significant Deterioration (PSD) 3.1 This facility is categorized as a NANSR major stationary source (Potential to Emit of NOx >100 tons/year). Future modifications at this facility resulting in a significant net emissions increase (see Regulation No. 3, Part D, Sections II.A.26 and 42) for VOC or NOx or a modification which is major by itself (Potential to Emit > 100 tons/year or either VOC or NOx) may result in the application of the NANSR review requirements. 3.2 This facility is categorized as a PSD major stationary source (Potential to Emit > 100 tons/yr) for NOx and CO. Future modifications at this facility resulting in a significant net emissions increase (see Regulation 3, Part D, Section II.A.26 and 42) for any pollutant as listed in Regulation No. 3, Part D, Section II.A.42 for which the area is in attainment or attainment/maintenance or a modification which is major by itself may result in the application of the PSD review requirements. 3.3 There are no other Operating Permits associated with this facility for purposes of determining applicability of NANSR and PSD review regulations. 4. Accidental Release Prevention Program (112(r)) 4.1 Based on the information provided by the applicant, this facility is not subject to the provisions of the Accidental Release Prevention Program (section 112(r) of the Federal Clean Air Act). 5. Compliance Assurance Monitoring (CAM) 5.1 The following emission points at this facility use a control device to achieve compliance with an emission limitation or standard to which they are subject and have pre-control emissions that exceed or are equivalent to the major source threshold. They are therefore subject to the provisions of the CAM program as set forth in 40 CFR Part 64, as adopted by reference in Colorado Regulation No. 3, Part C, Section XIV: The turbines are not subject to CAM since at the time the CAM plan was required the Title V permit specified a continuous compliance determination method (40 CFR Part 64 § 64.2(b)(1)(vi), as adopted by reference in Colorado Regulation No. 3, Part C, Section XIV).

Best Available Control Technology (BACT) shall be applied for control of Nitrogen Oxides (NOx), Carbon Monoxide (CO), Particulate Matter Emissions (PM and PMio) and Volatile Organic Compounds (VOC). BACT has been determined as follows: Operating Permit Number: 95OPWE096 First Issued: 1/1/99 Renewed: DRAFT • Air Pollution Control Division Thermo Cogeneration Partnership, L.P., A Delaware Limited Partnership Colorado Operating Permit Ft. Lupton Cogeneration Facility Permit # 95OPWE096 Page 9 1.1.1 BACT for NOx has been determined to be enhanced steam injection technology and emission limits as identified in Condition 1.4.2 (Colorado Construction Permit 91WE667). 1.1.2 BACT for CO has been determined to be use of good combustion practices and the emission limits as identified in Condition 1.5.2 (Colorado Construction Permit 91 WE667). 1.1.3 BACT for PM and PMio has been determined to be use of pipeline natural gas as fuel, as defined in Condition 1.10 (Colorado Construction Permit 91WE667). 1.1.4 BACT for VOC has been determined to be use of good combustion practices, use of pipeline natural gas as fuel, as defined in Condition 1.10, and the emission limits identified in Condition 1.6.2 (Colorado Construction Permit 91WE667, as modified under the provisions of Section I, Condition 1.3 to identify VOC BACT determination). 1.2 Particulate Matter Emissions are subject to the following requirements: 1.2.1 Annual emissions of PM and PMio from each turbine/duct burner combination AND from all turbine/duct burner combinations combined shall not exceed the limitations stated above (Colorado Construction Permit 91WE667). Emissions from each emission unit shall be calculated by the end of the subsequent month using the above emission factors (for turbine, from AP-42, Section 3.1 (dated April 2000), Table 3.1-2a, for duct burners, from manufacturer, as indicated in September 13, 1991 memo from Nooter/Eriksen Cogeneration Systems, Inc.), the monthly natural gas consumption and the higher heating value of the fuel (see Condition 1.11) in the following equations: Turbine: tons/month=(EF, lbs/MMBtu)x(Fuel Use, MMSCF/mo) x(Heat Content of Fuel, MMBtu/MMSCF) 2000 lbs/ton Duct Burner: tons/month=(EF, lbs/MMBtu)x(Fuel Use,MMSCF/mo)x(Heat Content of Fuel, MMBtu/MMSCF) 2000 lbs/ton Monthly emissions from each turbine and duct burner will be summed together and used in a twelve month rolling total to monitor compliance with the individual unit annual emission limitation. Each month a new twelve month rolling total shall be calculated using the previous twelve months' data. Monthly emissions from each turbine and duct burner combination will be summed together and used in a twelve month rolling total to monitor compliance with the annual emission limitation for all units combined. Each month a new twelve month rolling total shall be calculated using the previous twelve months' data. Operating Permit Number: 95OPWE096 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Cogeneration Partnership, L.P., A Delaware Limited Partnership Colorado Operating Permit Ft. Lupton Cogeneration Facility Permit# 95OPWE096 Page 10 1.2.2 Particulate Matter (PM) emissions from each turbine and each turbine/duct burner combination shall not exceed the above limitations (Colorado Regulation No. 1, Section III.A.1.b). In the absence of credible evidence to the contrary, compliance with the particulate matter emission limits is presumed since only pipeline natural gas that meets the requirements in Condition 1.10 is permitted to be used as fuel in the turbines and the duct burners. The numeric PM standards were determined as follows: For simple cycle operation or combined cycle operation without supplemental fuel (turbine only) the standard was determined using the design heat input for the turbine (400 mmBtu/hr) in the following equation: PE = 0.5 x (FI)-°'26' where: PE = particulate standard in lbs/mmBtu FI = fuel input in mmBtu/hr For combined cycle operation with supplemental fuel (turbine and duct burner), the standard was determined using the design heat input for the turbine (400 mmBtu/hr) and the duct burner(240 mmBtu/hr or 180 mmBtu/hr) in the following equation: PE (turbine/duct burner) = PET x FIT + PEN) x FINE FIT + FIoB 1.3 Sulfur Dioxide (SO2) emissions shall not exceed the following limitations: 1.3.1 Annual emissions of SO2 from each turbine/duct burner combination AND from all turbine/duct burner combinations combined shall not exceed the limitations stated above (Colorado Construction Permit 91WE667). Compliance with the annual SO2 emission limitations shall be monitored using the monitoring method specified in 40 CFR Part 75 Appendix D. Monthly emissions from each turbine and duct burner will be summed together and used in a twelve month rolling total to monitor compliance with the individual unit annual emission limitation. Each month a new twelve month rolling total shall be calculated using the previous twelve months' data. Monthly emissions from each turbine/duct burner combination will be summed together and used in a twelve month rolling total to monitor compliance with the annual emission limitation for all units combined. Each month a new twelve month rolling total shall be calculated using the previous twelve months' data. 1.3.2 Each turbine shall meet one of the following requirements: 1.3.2.1 Sulfur Dioxide (SO2) emissions from the turbine shall not exceed 150 ppmvd at 15% O2, Operating Permit Number: 95OPWE096 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Cogeneration Partnership, L.P., A Delaware Limited Partnership Colorado Operating Permit Ft. Lupton Cogeneration Facility Permit# 95OPWE096 Page 11 OR 1.3.2.2 No fuel, which contains sulfur in excess of 0.8 percent by weight, shall be used in this combustion turbine (40 CFR Part 60 Subpart GG §§ 60.333(a) & (b), as adopted by reference in Colorado Regulation No. 6, Part A). In the absence of credible evidence to the contrary, compliance with the above requirements is presumed since only pipeline natural gas is permitted to be used as fuel. The pipeline natural gas used as fuel shall meet the requirements in Condition 1.10. 1.3.3 Sulfur Dioxide (SO2) emissions from each turbine shall not exceed 0.35 lbs/MMBtu, on a 3-hr rolling average (Colorado Regulation No. 1, Section VI.B.4.c.(ii) and VI.B.2). In the absence of credible evidence to the contrary, compliance with the SO2 limitations is presumed since only pipeline natural gas that meets the requirements in Condition 1.10 is permitted to be used as fuel in each turbine. 1.4 Nitrogen Oxide (NOx) emissions shall not exceed the following: 1.4.1 Annual emissions of NOx from each turbine/duct burner combination AND from all turbine/duct burner combinations combined shall not exceed the limitations stated above (Colorado Construction Permit 91 WE667). Monthly emissions from each turbine/duct burner combination shall be determined using the continuous emission monitoring system required by Condition 1.8. Monthly emissions from each turbine/duct burner combination shall be used in a twelve month rolling total to monitor compliance with the individual unit annual emission limitation. Each month a new twelve month rolling total shall be calculated using the previous twelve months' data. Monthly emissions from each turbine/duct burner combination will be summed together and used in a twelve month rolling total to monitor compliance with the annual emission limitation for all units combined. Each month a new twelve month rolling total shall be calculated using the previous twelve months' data. 1.4.2 For BACT purposes, NOx emissions from each turbine/duct burner combination shall not exceed the following limitations (Colorado Construction Permit 91WE667, as modified under the provisions of Section I, Condition 1.3 and Colorado Regulation No. 3, Part C, Sections I.A.7 and III.B.7 to include alternate BACT limits for periods of startup and shutdown): 1.4.2.1 Except as provided for in Condition 1.4.2.2, NOx emissions shall not exceed 25 ppmvd at 15% O2, on a daily average. Compliance with the NOx BACT limit shall be monitored using the CEMS required by Condition 1.8. Except as provided for in Condition 1.4.2.2, the daily average shall be determined using all operating hours during every Operating Permit Number: 95OPWE096 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Cogeneration Partnership, L.P., A Delaware Limited Partnership Colorado Operating Permit Ft. Lupton Cogeneration Facility Permit# 95OPWE096 Page 12 midnight to midnight period. This includes any partial hours as described in Condition 1.4.2.2 below. 1.4.2.2 During periods of startup and shutdown, NOx emissions shall not exceed 38 lbs during each startup and/or shutdown event. Compliance with the startup and shutdown NOx BACT limits shall be monitored using the CEMS required by Condition 1.8. All CEMS data points within the startup and/or shutdown period shall be summed together to determine the NOx emissions for each startup and/or shutdown event. In the event that the startup ends within a clock hour or the shutdown begins within a clock hour, all non-startup and/or non-shutdown data points within that clock hour shall be included in the daily average required by Condition 1.4.2.1. 1.4.2.3 "Startup" means the setting in operation of any air pollution source for any purpose. Setting in operation for these turbines begins when fuel is injected into the turbine. Setting in operation for these turbines ends when the turbine reaches 15 MW or steam injection is initiated, whichever comes first. 1.4.2.4 "Shutdown" means the cessation of operation of any air pollution source for any purpose. The cessation of operation for these turbines begins when the command signal is initiated by the turbine operator to shutdown the unit and ends when fuel is no longer being fired in the turbine. 1.4.3 Nitrogen Oxide (NOx) Emissions from each turbine shall not exceed 126.9 ppmvd at 15% O2, on a 4-hour rolling average (40 CFR Part 60 Subparts GG §§ 60.332(a)(1) and 60.334(j)(1)(iii)(A), as adopted by reference in Colorado Regulation No. 6, Part A). Compliance with the NOx limitation shall be monitored using the continuous emission monitoring system required by Condition 1.8. The permittee has elected to not correct emissions to International Organization for Standardization (ISO) standard day conditions as allowed in Condition 5.3. Note that the NOx emission limitations are not applicable during times of startup, shutdown and malfunction. However, those instances during startup, shutdown and malfunction when the NOx limitation is exceeded shall be identified in the Excess Emission Report required in Condition 5.4. For purposes of the reports required by Condition 5.4, the following applies: 1.4.3.1 Excess emissions shall be reported for all periods of unit operation, including startup, shutdown and malfunction (40 CFR Part 60 Subpart GG § 60.334(j)). 1.4.3.2 An hour of excess emissions shall be any unit operating hour (any clock hour during which fuel is combusted) in which the 4-hour rolling average NOx concentration exceeds the applicable emission limit in Condition Operating Permit Number: 95OPWE096 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Cogeneration Partnership, L.P., A Delaware Limited Partnership Colorado Operating Permit Ft. Lupton Cogeneration Facility Permit# 95OPWE096 Page 13 1.4.3. For the purposes of 40 CFR Part 60 Subpart GG, a "4-hour rolling average NOx concentration" is the arithmetic average of the average NOx concentration measured by the CEMS for a given hour (corrected to 15 percent O2) and the three unit operating hour average NOx concentrations immediately preceding that unit operating hour (40 CFR Part 60 Subpart GG § 60.334(j)(1)(iii)(A)). 1.4.3.3 A period of monitor downtime shall be any unit operating hour in which sufficient data are not obtained to validate the hour, for either NOx concentration or diluent (or both) (40 CFR Part 60 Subpart GG § 60.334(j)(1)(iii)(B)). Note that since the permittee has elected to not correct emissions to ISO standard ambient conditions, as allowed in Condition 5.3.3.1, ambient conditions at the time of the excess emission period do not have to be reported as specified in 40 CFR Part 60 Subpart GG § 60.334(j)(1)(iii)(C). 1.5 Emissions of Carbon Monoxide (CO) shall not exceed the following limitations: 1.5.1 Annual emissions of CO from each turbine/duct burner combination AND from all turbine/duct burner combinations combined shall not exceed the limitations stated above (Colorado Construction Permit 91 WE667). Monthly emissions from each turbine/duct burner combination shall be determined using the continuous emission monitoring system required by Condition 1.8. Monthly emissions from each turbine/duct burner combination shall be used in a twelve month rolling total to monitor compliance with the individual unit annual emission limitation. Each month a new twelve month rolling total shall be calculated using the previous twelve months' data. Monthly emissions from each turbine/duct burner combination will be summed together and used in a twelve month rolling total to monitor compliance with the annual emission limitation for all units combined. Each month a new twelve month rolling total shall be calculated using the previous twelve months' data. 1.5.2 For BACT purposes, CO emissions from each turbine/duct burner combination shall not exceed the following (Colorado Construction Permit 91 WE667, as provided for under the provisions of Section I, Condition 1.3 and Colorado Regulation No. 3, Part C, Sections I.A.7 and III.B.7 to include alternate BACT limits for periods of startup and shutdown): 1.5.2.1 Except as provided for in Condition 1.5.2.2, CO emissions shall not exceed 25 ppmvd at 15% O2, on a daily average. Compliance with the CO BACT limit shall be monitored using the continuous emission monitoring system required by Condition 1.8. Except as provided for in Condition 1.5.2.2, the daily average shall be determined using all operating hours during every midnight-to-midnight period. This includes any partial hours Operating Permit Number: 95OPWE096 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Cogeneration Partnership, L.P., A Delaware Limited Partnership Colorado Operating Permit Ft. Lupton Cogeneration Facility Permit # 95OPWE096 Page 14 as described in Condition 1.5.2.2 below. 1.5.2.2 During periods of startup and shutdown, CO emissions shall not exceed 25 lbs during each startup and/or shutdown event. Compliance with the startup and shutdown CO BACT limits shall be monitored using the CEMS required by Condition 1.8. All CEMS data points within the startup and/or shutdown period shall be summed together to determine the CO emissions for each startup and/or shutdown event. In the event that the startup ends within a clock hour or the shutdown begins within a clock hour, all non-startup and/or non-shutdown data points within that clock hour shall be included in the daily average required by Condition 1.5.2.1. 1.5.2.3 "Startup" shall have the same definition as provided for in Condition 1.4.2.3. 1.5.2.4 "Shutdown" shall have the same definition as provided for in Condition 1.4.2.4. 1.6 Volatile Organic Compound (VOC) emissions shall not exceed the following limitations: 1.6.1 Annual emissions of VOC from each turbine/duct burner combination AND from all turbine/duct burner combinations combined shall not exceed the limitations stated above (Colorado Construction Permit 91WE667). Emissions from each emission unit shall be calculated by the end of the subsequent month using the above emission factors (for turbines and duct burners, from turbine manufacturer, the November 1997 performance test indicates emissions from both the turbine alone and the turbine and duct burner together are well below this emission factor), the monthly natural gas consumption and the higher heating value of the fuel (see Condition 1.11) in the equations in Condition 1.2.1 of this permit. Monthly emissions from each turbine and duct burner will be summed together and used in a twelve month rolling total to monitor compliance with the individual unit annual emission limitation. Each month a new twelve month rolling total shall be calculated using the previous twelve months' data. Monthly emissions from each turbine/duct burner combination will be summed together and used in a twelve month rolling total to monitor compliance with the annual emission limitation for all units combined. Each month a new twelve month rolling total shall be calculated using the previous twelve months' data. 1.6.2 For BACT purposes, VOC emissions from each turbine/duct burner combination shall not exceed 3.63 lbs/hr (Colorado Construction Permit 91WE667). In the absence of credible evidence to the contrary, compliance with the VOC BACT limit is presumed provided that the turbines and duct burners are operated and maintained in accordance with manufacturer's recommendations and good engineering practices and that the natural gas used as fuel meets the requirement in Condition 1.10.

National Emission Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines (40 CFR Part 63 Subpart ZZZZ) 6.1 The diesel-fired emergency generator and fire pump engines are subject to the requirements in 40 CFR Part 63 Subpart ZZZZ, "National Emission Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines", as follows: These requirements included in this Condition 6.1 are only federally enforceable. As of the date of revised permit issuance (DATE], the requirements in 40 CFR Part 63 Subpart ZZZZ promulgated on March 3, 2010 have not been adopted into Colorado Regulation No. 8, Part E by the Division and are therefore not state-enforceable. In the event that the Division adopts these requirements these engines will be subject to the APEN reporting and minor source permitting requirements and these requirements will be state-enforceable. When do I have to comply with this subpart (5C 60.6595) 6.1.1 If you have an existing stationary CI RICE located at an area source of HAP emissions, you must comply with the applicable emission limitations and operating limitations no later than May 3, 2013. (§ 63.6595(a)(I)) What emission limitations and operating limitations must I meet if I own or operate an existing CI RICE located at an area source of HAP emissions (§ 63.6603) 6.1.2 If you own or operate an existing stationary CI RICE located at an area source of HAP emissions, you must comply with the requirements in Table 2d to this subpart and the operating limitations in Table 2b to this subpart which apply to you. (§ 63.6603(a)) The requirements in Table 2d that apply to these emergency CI RICE are as follows: 6.1.2.1 Change oil and filter every 500 hours of operation or annually whichever Operating Permit Number: 95OPWE096 First Issued: 1/1/99 Renewed: DRAFT • Air Pollution Control Division Thermo Cogeneration Partnership, L.P., A Delaware Limited Partnership Colorado Operating Permit Ft. Lupton Cogeneration Facility Permit # 95OPWE096 Page 29 comes first. (Table 2d, item 4.a) 6.1.2.2 Inspect air cleaner every 1,000 hours of operation or annually whichever comes first. (Table 2d, item 4.b) 6.1.2.3 Inspect all hoses and belts every 500 hours of operation or annually whichever comes first, and replace as necessary. (Table 2d, item 4.c) Notwithstanding the above requirements, the following applies: 6.1.2.4 Sources have the option to utilize an oil analysis program as described in Condition 6.1.8 in order to extend the specified oil change requirement in Condition 6.1.2.1. (Table 2d, footnote I) 6.1.2.5 If an emergency engine is operating during an emergency and it is not possible to shut down the engine in order to perform the management practice requirements on the schedule required in Conditions 6.1.2.1 through 6.1.2.3, or if performing the management practice on the required schedule would otherwise pose an unacceptable risk under Federal, State, or local law, the management practice can be delayed until the emergency is over or the unacceptable risk under Federal, State, or local law has abated. The management practice should be performed as soon as practicable after the emergency has ended or the unacceptable risk under Federal, State, or local law has abated. Sources must report any failure to perform the management practice on the schedule required and the Federal, State or local law under which the risk was deemed unacceptable. (Table 2d, footnote 2) What are my general requirements for complying with this subpart? (§ 63.6605) 6.1.3 You must be in compliance with the emission limitations and operating limitations in this subpart that apply to you at all times. (§ 63.6605(a)) 6.1.4 At all times you must operate and maintain any affected source, including associated air pollution control equipment and monitoring equipment, in a manner consistent with safety and good air pollution control practices for minimizing emissions. The general duty to minimize emissions does not require you to make any further efforts to reduce emissions if levels required by this standard have been achieved. Determination of whether such operation and maintenance procedures are being used will be based on information available to the Division which may include, but is not limited to, monitoring results, review of operation and maintenance procedures, review of operation and maintenance records, and inspection of the source. (§ 63.6605(b)) What are my monitoring, installation, collection, operation, and maintenance requirements? (§ 63.6625) Operating Permit Number: 95OPWE096 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Thermo Cogeneration Partnership, L.P., A Delaware Limited Partnership Colorado Operating Permit Ft.

(§ 63.6625(e)) 6.1.6 If you own or operate an existing emergency stationary RICE with a site rating of less than or equal to 500 brake HP located at a major source of HAP emissions or an existing emergency stationary RICE located at an area source of HAP emissions, you must install a non-resettable hour meter if one is not already installed. (§ 63.6625(O) 6.1.7 If you operate a new or existing stationary engine, you must minimize the engine's time spent at idle during startup and minimize the engine's startup time to a period needed for appropriate and safe loading of the engine, not to exceed 30 minutes, after which time the emission standards applicable to all times other than startup in Tables la, 2a, 2c, and 2d to this subpart apply. (§ 63.6625(h)) 6.1.8 If you own or operate a stationary engine that is subject to the work, operation or management practices in Condition 6.1.2.1, you have the option of utilizing an oil analysis program in order to extend the specified oil change requirement in Condition 6.1.2.1. The oil analysis must be performed at the same frequency specified for changing the oil in Condition 6.1.2.1. The analysis program must at a minimum analyze the following three parameters: Total Base Number, viscosity, and percent water content. The condemning limits for these parameters are as follows: Total Base Number is less than 30 percent of the Total Base Number of the oil when new; viscosity of the oil has changed by more than 20 percent from the viscosity of the oil when new; or percent water content (by volume) is greater than 0.5. If all of these condemning limits are not exceeded, the engine owner or operator is not required to change the oil. If any of the limits are exceeded, the engine owner or operator must change the oil before continuing to use the engine. The owner or operator must keep records of the parameters that are analyzed as part of the program, the results of the analysis, and the oil changes for the engine. The analysis program must be part of the maintenance plan for the engine. (§ 63.6625(O) How do I demonstrate continuous compliance with the emission limitations and operating limitations? 63.6640) 6.1.9 If you own or operate an existing emergency stationary RICE with a site rating of less than or equal to 500 brake HP located at a major source of HAP emissions, a new emergency stationary RICE with a site rating of more than 500 brake HP located at a major source of HAP emissions that was installed on or after June 12, 2006, or an Operating Permit Number: 95OPWE096 First Issued: 1/1/99 Renewed: DRAFT • Air Pollution Control Division Thermo Cogeneration Partnership, L.P., A Delaware Limited Partnership Colorado Operating Permit Ft.

(§ 63.6640(O) 6.1.9.1 For owners and operators of emergency engines, any operation other than emergency operation, maintenance and testing, and operation in non- emergency situations for 50 hours per year, as permitted in this section, is prohibited. (§ 63.6640(O(1)) 6.1.9.2 There is no time limit on the use of emergency stationary RICE in emergency situations. (§ 63.6640(O(2)) 6.1.9.3 You may operate your emergency stationary RICE for the purpose of maintenance checks and readiness testing, provided that the tests are recommended by Federal, State or local government, the manufacturer, the vendor, or the insurance company associated with the engine. Maintenance checks and readiness testing of such units is limited to 100 hours per year. The owner or operator may petition the Administrator for approval of additional hours to be used for maintenance checks and readiness testing, but a petition is not required if the owner or operator maintains records indicating that Federal, State, or local standards require maintenance and testing of emergency RICE beyond 100 hours per year. (§ 63.6640(O(3)) 6.1.9.4 You may operate your emergency stationary RICE up to 50 hours per year in non-emergency situations, but those 50 hours are counted towards the 100 hours per year provided for maintenance and testing. The 50 hours per year for non-emergency situations cannot be used for peak shaving or to generate income for a facility to supply power to an electric grid or otherwise supply power as part of a financial arrangement with another entity; except that owners and operators may operate the emergency engine for a maximum of 15 hours per year as part of a demand response program if the regional transmission organization or equivalent balancing authority and transmission operator has determined there are emergency conditions that could lead to a potential electrical blackout, such as unusually low frequency, equipment overload, capacity or energy deficiency, or unacceptable voltage level. The engine may not be operated for more than 30 minutes prior to the time when the emergency condition is expected to occur, and the engine operation must be terminated immediately after the facility is notified that the emergency condition is no longer imminent. The 15 hours per year of demand response operation are counted as part of the 50 hours of operation per year provided for non- emergency situations. The supply of emergency power to another entity or entities pursuant to financial arrangement is not limited by this Condition 6.1.9.4, as long as the power provided by the financial arrangement is limited to emergency power.

Lupton Cogeneration Facility Permit# 95OPWE096 Page 42 b. Emission Monitoring Requirements The Division may require owners or operators of stationary air pollution sources to install,maintain, and use instrumentation to monitor and record emission data as a basis for periodic reports to the Division. c. Performance Testing The owner or operator of any air pollution source shall,upon request of the Division,conduct performance test(s) and furnish the Division a written report of the results of such test(s) in order to determine compliance with applicable emission control regulations. Performance test(s) shall be conducted and the data reduced in accordance with the applicable reference test methods unless the Division: (i) specifies or approves, in specific cases,the use of a test method with minor changes in methodology; (ii) approves the use of an equivalent method; (iii) approves the use of an alternative method the results of which the Division has determined to be adequate for indicating where a specific source is in compliance; or (iv) waives the requirement for performance test(s)because the owner or operator of a source has demonstrated by other means to the Division's satisfaction that the affected facility is in compliance with the standard. Nothing in this paragraph shall be construed to abrogate the Commission's or Division's authority to require testing under the Colorado Revised Statutes,Title 25,Article 7, and pursuant to regulations promulgated by the Commission. Compliance test(s)shall be conducted under such conditions as the Division shall specify to the plant operator based on representative performance of the affected facility. The owner or operator shall make available to the Division such records as maybe necessary to determine the conditions of the performance test(s). Operations during period of startup, shutdown, and malfunction shall not constitute representative conditions of performance test(s)unless otherwise specified in the applicable standard. The owner or operator of an affected facility shall provide the Division thirty days prior notice of the performance test to afford the Division the opportunity to have an observer present. The Division may waive the thirty day notice requirement provided that arrangements satisfactory to the Division are made for earlier testing. The owner or operator of an affected facility shall provide, or cause to be provided, performance testing facilities as follows: (i) Sampling ports adequate for test methods applicable to such facility; (ii) Safe sampling platform(s); (iii) Safe access to sampling platform(s); and (iv) Utilities for sampling and testing equipment. Each performance test shall consist of at least three separate runs using the applicable test method. Each run shall be conducted for the time and under the conditions specified in the applicable standard. For the purpose of determining compliance with an applicable standard, the arithmetic mean of results of at least three runs shall apply. In the event that a sample is accidentally lost or conditions occur in which one of the runs must be discontinued because of forced shutdown, failure of an irreplaceable portion of the sample train, extreme meteorological conditions, or other circumstances beyond the owner or operator's control, compliance may, upon the Division's approval, be determined using the arithmetic mean of the results of the two other runs.

Lupton Cogeneration Facility Permit # 95OPWE096 Page 43 Nothing in this section shall abrogate the Division's authority to conduct its own performance test(s) if so warranted. d. Affirmative Defense Provision for Excess Emissions during Malfunctions Note that until such time as the U.S. EPA approves this provision into the Colorado State Implementation Plan (SIP), it shall be enforceable only by the State. An affirmative defense to a claim of violation under these regulations is provided to owners and operators for civil penalty actions for excess emissions during periods of malfunction. To establish the affirmative defense and to be relieved of a civil penalty in any action to enforce an applicable requirement,the owner or operator of the facility must meet the notification requirements below in a timely manner and prove by a preponderance of evidence that: (i) The excess emissions were caused by a sudden, unavoidable breakdown of equipment, or a sudden, unavoidable failure of a process to operate in the normal or usual manner, beyond the reasonable control of the owner or operator; (ii) The excess emissions did not stem from any activity or event that could have reasonably been foreseen and avoided, or planned for, and could not have been avoided by better operation and maintenance practices; (iii) Repairs were made as expeditiously as possible when the applicable emission limitations were being exceeded; (iv) The amount and duration of the excess emissions(including any bypass)were minimized to the maximum extent practicable during periods of such emissions; (v) All reasonably possible steps were taken to minimize the impact of the excess emissions on ambient air quality; (vi) All emissions monitoring systems were kept in operation(if at all possible); (vii) The owner or operator's actions during the period of excess emissions were documented by properly signed,contemporaneous operating logs or other relevant evidence; (viii) The excess emissions were not part of a recurring pattern indicative of inadequate design, operation, or maintenance; (ix) At all times, the facility was operated in a manner consistent with good practices for minimizing emissions. This section is intended solely to be a factor in determining whether an affirmative defense is available to an owner or operator, and shall not constitute an additional applicable requirement; and (x) During the period of excess emissions, there were no exceedances of the relevant ambient air quality standards established in the Commissions' Regulations that could be attributed to the emitting source. The owner or operator of the facility experiencing excess emissions during a malfunction shall notify the division verbally as soon as possible, but no later than noon of the Division's next working day, and shall submit written notification following the initial occurrence of the excess emissions by the end of the source's next reporting period. The notification shall address the criteria set forth above. The Affirmative Defense Provision contained in this section shall not be available to claims for injunctive relief The Affirmative Defense Provision does not apply to failures to meet federally promulgated performance standards or emission limits, including, but not limited to, new source performance standards and national emission standards for hazardous air pollutants. The affirmative defense provision does not apply to state implementation plan (sip) limits or permit limits that have been set taking into account potential emissions during malfunctions, including,but not necessarily limited to, certain limits with 30-day or longer averaging times, limits that indicate they apply during malfunctions, and limits that indicate they apply at all times or without exception.

Lupton Cogeneration Facility Permit# 95OPWE096 Page 44 e. Circumvention Clause A person shall not build, erect, install, or use any article, machine, equipment, condition, or any contrivance, the use of which, without resulting in a reduction in the total release of air pollutants to the atmosphere, reduces or conceals an emission which would otherwise constitute a violation of this regulation. No person shall circumvent this regulation by using more openings than is considered normal practice by the industry or activity in question. f. Compliance Certifications For the purpose of submitting compliance certifications or establishing whether or not a person has violated or is in violation of any standard in the Colorado State Implementation Plan,nothing in the Colorado State Implementation Plan shall preclude the use, including the exclusive use,of any credible evidence or information,relevant to whether a source would have been in compliance with applicable requirements if the appropriate performance or compliance test or procedure had been performed. Evidence that has the effect of making any relevant standard or permit term more stringent shall not be credible for proving a violation of the standard or permit term. When compliance or non-compliance is demonstrated by a test or procedure provided by permit or other applicable requirement,the owner or operator shall be presumed to be in compliance or non-compliance unless other relevant credible evidence overcomes that presumption. g. Affirmative Defense Provision for Excess Emissions During Startup and Shutdown An affirmative defense is provided to owners and operators for civil penalty actions for excess emissions during periods of startup and shutdown. To establish the affirmative defense and to be relieved of a civil penalty in any action to enforce an applicable requirement, the owner or operator of the facility must meet the notification requirements below in a timely manner and prove by a preponderance of the evidence that: (i) The periods of excess emissions that occurred during startup and shutdown were short and infrequent and could not have been prevented through careful planning and design; (ii) The excess emissions were not part of a recurring pattern indicative of inadequate design, operation or maintenance; (iii) If the excess emissions were caused by a bypass(an intentional diversion of control equipment), then the bypass was unavoidable to prevent loss of life,personal injury, or severe property damage; (iv) The frequency and duration of operation in startup and shutdown periods were minimized to the maximum extent practicable; (v) All possible steps were taken to minimize the impact of excess emissions on ambient air quality; (vi) All emissions monitoring systems were kept in operation(if at all possible); (vii) The owner or operator's actions during the period of excess emissions were documented by properly signed, contemporaneous operating logs or other relevant evidence; and, (viii) At all times, the facility was operated in a manner consistent with good practices for minimizing emissions. This subparagraph is intended solely to be a factor in determining whether an affirmative defense is available to an owner or operator, and shall not constitute an additional applicable requirement. The owner or operator of the facility experiencing excess emissions during startup and shutdown shall notify the Division verbally as soon as possible, but no later than two(2)hours after the start of the next working day, and shall submit written quarterly notification following the initial occurrence of the excess emissions. The notification shall address the criteria set forth above. The Affirmative Defense Provision contained in this section shall not be available to claims for injunctive relief. Operating Permit Number: 95OPWE096 First Issued: 1/1/99 Renewed: DRAFT • Air Pollution Control Division Thermo Cogeneration Partnership, L.P., A Delaware Limited Partnership Colorado Operating Permit Ft. Lupton Cogeneration Facility Permit # 95OPWE096 Page 45 The Affirmative Defense Provision does not apply to State Implementation Plan provisions or other requirements that derive from new source performance standards or national emissions standards for hazardous air pollutants, or any other federally enforceable performance standard or emission limit with an averaging time greater than twenty- four hours. In addition, an affirmative defense cannot be used by a single source or small group of sources where the excess emissions have the potential to cause an exceedance of the ambient air quality standards or Prevention of Significant Deterioration(PSD) increments. In making any determination whether a source established an affirmative defense,the Division shall consider the information within the notification required above and any other information the Division deems necessary,which may include, but is not limited to,physical inspection of the facility and review of documentation pertaining to the maintenance and operation of process and air pollution control equipment. 4. Compliance Requirements Regulation No. 3, 5 CCR 1001-5, Part C. §§ III.C.9.,V.C.I I. & 16.d. and § 25-7-122.1(2), C.R.S. a. The permittee must comply with all conditions of the Operating Permit. Any permit noncompliance relating to federally-enforceable terms or conditions constitutes a violation of the federal act, as well as the state act and Regulation No. 3. Any permit noncompliance relating to state-only terms or conditions constitutes a violation of the state act and Regulation No. 3, shall be enforceable pursuant to state law, and shall not be enforceable by citizens under § 304 of the federal act. Any such violation of the federal act,the state act or regulations implementing either statute is grounds for enforcement action, for permit termination, revocation and reissuance or modification or for denial of a permit renewal application. b. It shall not be a defense for a permittee in an enforcement action or a consideration in favor of a permittee in a permit termination,revocation or modification action or action denying a permit renewal application that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of the permit. c. The permit may be modified, revoked, reopened, and reissued, or terminated for cause. The filing of any request by the permittee for a permit modification, revocation and reissuance, or termination,or any notification of planned changes or anticipated noncompliance does not stay any permit condition, except as provided in §§ X. and Xl.of Regulation No.3, Part C. d. The permittee shall furnish to the Air Pollution Control Division, within a reasonable time as specified by the Division, any information that the Division may request in writing to determine whether cause exists for modifying, revoking and reissuing, or terminating the permit or to determine compliance with the permit. Upon request, the permittee shall also furnish to the Division copies of records required to be kept by the permittee, including information claimed to be confidential. Any information subject to a claim of confidentiality shall be specifically identified and submitted separately from information not subject to the claim. e. Any schedule for compliance for applicable requirements with which the source is not in compliance at the time of permit issuance shall be supplemental, and shall not sanction noncompliance with,the applicable requirements on which it is based. f. For any compliance schedule for applicable requirements with which the source is not in compliance at the time of permit issuance,the permittee shall submit, at least every 6 months unless a more frequent period is specified in the applicable requirement or by the Air Pollution Control Division, progress reports which contain the following: (i) dates for achieving the activities, milestones, or compliance required in the schedule for compliance, and dates when such activities, milestones, or compliance were achieved; and (ii) an explanation of why any dates in the schedule of compliance were not or will not be met, and any preventive or corrective measures adopted.

The permittee shall not knowingly falsify,tamper with, or render inaccurate any monitoring device or method required to be maintained or followed under the terms and conditions of the Operating Permit. 5. Emergency Provisions Regulation No. 3, 5 CCR 1001-5, Part C, & VII. An emergency means any situation arising from sudden and reasonably unforeseeable events beyond the control of the source, including acts of God, which situation requires immediate corrective action to restore normal operation, and that causes the source to exceed the technology-based emission limitation under the permit due to unavoidable increases in emissions attributable to the emergency. "Emergency" does not include noncompliance to the extent caused by improperly designed equipment, lack of preventative maintenance, careless or improper operation, or operator error. An emergency constitutes an affirmative defense to an enforcement action brought for noncompliance with a technology-based emission limitation if the permittee demonstrates,through properly signed, contemporaneous operating logs,or other relevant evidence that: a. an emergency occurred and that the permittee can identify the cause(s)of the emergency; b. the permitted facility was at the time being properly operated; c. during the period of the emergency the permittee took all reasonable steps to minimize levels of emissions that exceeded the emission standards, or other requirements in the permit; and d. the permittee submitted oral notice of the emergency to the Air Pollution Control Division no later than noon of the next working day following the emergency, and followed by written notice within one month of the time when emissions limitations were exceeded due to the emergency. This notice must contain a description of the emergency, any steps taken to mitigate emissions, and corrective actions taken. This emergency provision is in addition to any emergency or malfunction provision contained in any applicable requirement. 6.

If a conviction of any person under this paragraph is for a violation committed after a first conviction of such person under this paragraph, the maximum punishment shall be doubled with respect to both the fine and imprisonment. The permittee must comply with all conditions of this operating permit. Any permit noncompliance constitutes a violation of the Act and is grounds for enforcement action; for permit termination, revocation and reissuance, or modification; or for denial of a permit renewal application. The Part 70 Operating Permit program requires three types of reports to be filed for all permits. All required reports must be certified by a responsible official. Report#1: Monitoring Deviation Report(due at least every six months) For purposes of this operating permit, the Division is requiring that the monitoring reports are due every six months unless otherwise noted in the permit. All instances of deviations from permit monitoring requirements must be clearly identified in such reports. For purposes of this operating permit, monitoring means any condition determined by observation, by data from any monitoring protocol, or by any other monitoring which is required by the permit as well as the recordkeeping associated with that monitoring. This would include, for example, fuel use or process rate monitoring, fuel analyses, and operational or control device parameter monitoring. Report#2: Permit Deviation Report (must be reported "promptly") In addition to the monitoring requirements set forth in the permits as discussed above, each and every requirement of the permit is subject to deviation reporting. The reports must address deviations from permit requirements, including those attributable to malfunctions as defined in this Appendix, the probable cause of Operating Permit Number: 95OPWE096 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Colorado Operating Permit Appendix B Monitoring and Permit Deviation Report Page 2 such deviations, and any corrective actions or preventive measures taken. All deviations from any term or condition of the permit are required to be summarized or referenced in the annual compliance certification. For purposes of this operating permit, "malfunction" shall refer to both emergency conditions and malfunctions. Additional discussion on these conditions is provided later in this Appendix. For purposes of this operating permit, the Division is requiring that the permit deviation reports are due as set forth in General Condition 21. Where the underlying applicable requirement contains a definition of prompt or otherwise specifies a time frame for reporting deviations, that definition or time frame shall govern. For example, quarterly Excess Emission Reports required by an NSPS or Regulation No. 1, Section IV. In addition to the monitoring deviations discussed above, included in the meaning of deviation for the purposes of this operating permit are any of the following: (1) A situation where emissions exceed an emission limitation or standard contained in the permit; (2) A situation where process or control device parameter values demonstrate that an emission limitation or standard contained in the permit has not been met; (3) A situation in which observations or data collected demonstrates noncompliance with an emission limitation or standard or any work practice or operating condition required by the permit; or, (4) A situation in which an excursion or exceedance as defined in 40CFR Part 64 (the Compliance Assurance Monitoring (CAM) Rule) has occurred. (only if the emission point is subject to CAM) For reporting purposes, the Division has combined the Monitoring Deviation Report with the Permit Deviation Report. All deviations shall be reported using the following codes: 1 =Standard: When the requirement is an emission limit or standard 2 = Process: When the requirement is a production/process limit 3 = Monitor: When the requirement is monitoring 4 = Test: When the requirement is testing 5 = Maintenance: When required maintenance is not performed 6 = Record: When the requirement is recordkeeping 7 = Report: When the requirement is reporting 8= CAM: A situation in which an excursion or exceedance as defined in 40CFR Part 64 (the Compliance Assurance Monitoring (CAM) Rule) has occurred. 9 = Other: When the deviation is not covered by any of the above categories Report#3: Compliance Certification (annually, as defined in the permit) Submission of compliance certifications with terms and conditions in the permit, including emission limitations, standards, or work practices, is required not less than annually. Compliance Certifications are intended to state the compliance status of each requirement of the permit over the certification period. They must be based, at a minimum, on the testing and monitoring methods specified in the Operating Permit Number: 95OPWE096 First Issued: I/1/99 Renewed: DRAFT • Air Pollution Control Division Colorado Operating Permit Appendix B Monitoring and Permit Deviation Report Page 3 permit that were conducted during the relevant time period. In addition, if the owner or operator knows of other material information (i.e. information beyond required monitoring that has been specifically assessed in relation to how the information potentially affects compliance status), that information must be identified and addressed in the compliance certification. The compliance certification must include the following: • The identification of each term or condition of the permit that is the basis of the certification; • Whether or not the method(s) used by the owner or operator for determining the compliance status with each permit term and condition during the certification period was the method(s) specified in the permit. Such methods and other means shall include, at a minimum, the methods and means required in the permit. If necessary, the owner or operator also shall identify any other material information that must be included in the certification to comply with section 113(c)(2) of the Federal Clean Air Act, which prohibits knowingly making a false certification or omitting material information; • The status of compliance with the terms and conditions of the permit, and whether compliance was continuous or intermittent. The certification shall identify each deviation and take it into account in the compliance certification. Note that not all deviations are considered violations.' • Such other facts as the Division may require, consistent with the applicable requirements to which the source is subject, to determine the compliance status of the source. The Certification shall also identify as possible exceptions to compliance any periods during which compliance is required and in which an excursion or exceedance as defined under 40 CFR Part 64 (the Compliance Assurance Monitoring (CAM) Rule) has occurred. (only for emission points subject to CAM) Note the requirement that the certification shall identify each deviation and take it into account in the compliance certification. Previously submitted deviation reports, including the deviation report submitted at the time of the annual certification, may be referenced in the compliance certification. Startup, Shutdown, Malfunctions and Emergencies Understanding the application of Startup, Shutdown, Malfunctions and Emergency Provisions, is very important in both the deviation reports and the annual compliance certifications. Startup, Shutdown, and Malfunctions Please note that exceedances of some New Source Performance Standards (NSPS) and Maximum Achievable Control Technology (MACT) standards that occur during Startup, Shutdown or Malfunctions may not be considered to be non-compliance since emission limits or standards often do not apply unless specifically stated in the NSPS. Such exceedances must, however, be reported as excess emissions per the NSPS/MACT rules and would still be noted in the deviation report. In regard to compliance certifications, the permittee should be ' For example, given the various emissions limitations and monitoring requirements to which a source may be subject, a deviation from one requirement may not be a deviation under another requirement which recognizes an exception and/or special circumstances relating to that same event. Operating Permit Number: 95OPWE096 First Issued: 1/1/99 Renewed: DRAFT Air Pollution Control Division Colorado Operating Permit Appendix B Monitoring and Permit Deviation Report Page 4 confident of the information related to those deviations when making compliance determinations since they are subject to Division review. The concepts of Startup, Shutdown and Malfunctions also exist for Best Available Control Technology (BACT) sources, but are not applied in the same fashion as for NSPS and MACT sources. Emergency Provisions Under the Emergency provisions of Part 70 certain operational conditions may act as an affirmative defense against enforcement action if they are properly reported. DEFINITIONS Malfunction (NSPS) means any sudden, infrequent, and not reasonably preventable failure of air pollution control equipment, process equipment, or a process to operate in a normal or usual manner. Failures that are caused in part by poor maintenance or careless operation are not malfunctions. Malfunction (SIP) means any sudden and unavoidable failure of air pollution control equipment or process equipment or unintended failure of a process to operate in a normal or usual manner. Failures that are primarily caused by poor maintenance, careless operation, or any other preventable upset condition or preventable equipment breakdown shall not be considered malfunctions. Emergency means any situation arising from sudden and reasonably unforeseeable events beyond the control of the source, including acts of God, which situation requires immediate corrective action to restore normal operation, and that causes the source to exceed a technology-based emission limitation under the permit, due to unavoidable increases in emissions attributable to the emergency. An emergency shall not include noncompliance to the extent caused by improperly designed equipment, lack of preventative maintenance, careless or improper operation, or operator error.

If deviations were noted in the current deviation report (i.e. for the last six months of the annual reporting period), put an "X" under"current". Mark both columns if both apply. 2 Note whether the method(s) used to determine the compliance status with each term and condition was the method(s)specified in the permit. If it was not, mark "no"and attach additional information/explanation. 3 Note whether the compliance status with of each term and condition provided was continuous or intermittent. "Intermittent Compliance" can mean either that noncompliance has occurred or that the owner or operator has data sufficient to certify compliance only on an intermittent basis. Certification of intermittent compliance therefore does not necessarily mean that any noncompliance has occurred. NOTE: The Periodic Monitoring requirements of the Operating Permit program rule are intended to provide assurance that even in the absence of a continuous system of monitoring the Title V source can demonstrate whether it has operated in continuous compliance for the duration of the reporting period. Therefore, if a source I) conducts all of the monitoring and recordkeeping required in its permit, even if such activities are done periodically and not continuously, and if 2) such monitoring and recordkeeping does not indicate non-compliance, and if 3) the Responsible Official is not aware of any credible evidence that indicates non-compliance, then the Responsible Official can certify that the emission point(s) in question were in continuous compliance during the applicable time period. °Compliance status for these sources shall be based on a reasonable inquiry using readily available information.

O. Box 208 Ft. Lupton, CO 80621 SUBJECT: Draft Renewal Operating Permit for Public Service Company— Ft. Lupton Cogeneration Facility Dear Mr. Rhoads: Enclosed please find a draft of the renewal operating permit for your facility as well as a copy of the technical review summary document. Please review and submit any comments you may have concerning the modified draft operating permit. Following our review of your comments, we will send the draft permit out for a 30-day Public Comment period and then to EPA for their 45-day review period. The regulations also require that the applicant receive written notice of their right to a formal hearing before the Colorado Air Quality Control Commission at the same time that the Public Comment packet goes out. You will receive a separate letter containing that information. This draft renewal permit contains the modifications that you requested in your renewal application received on May 17, 2010. The permit was also revised to be more consistent with recently issued permits, correct errors, omissions and discrepancies identified during inspections and/or review of the renewal application and incorporate EPA comments made on other operating permits for similar sources. The changes are summarized in the technical review document for the renewal permit. While you are reviewing this permit, please be aware of the following: 1. Since the original issuance of this permit, EPA has promulgated National Emission Standards for Hazardous Air Pollutant Emissions (NESHAP) for reciprocating internal combustion engines (RICE) located at area sources and Standards of Performance (NSPS) for both compression ignition and spark ignition engines. These requirements apply to both new and existing engines and apply to any size engine, many of which could otherwise be considered insignificant activities. The appropriate requirements for existing engines have been incorporated into the draft renewal permit. However, the Division must determine if there are any new engines located at your facility that could be subject to these new requirements and would have to be included in Section II of the permit. Please indicate whether you have any engines that would meet the following requirements: Mr. Richard Rhoads, Facility Manager August 4, 2010 Draft Renewal Operating Permit Page 2 Requirements Applicability Date Engine Type/Size H 40 CFR Part 63 Subpart ZZZZ Constructed and/or reconstructed Both Compression Ignition and after 6/12/06 Spark Ignition, all sizes 40 CFR Part 60 Subpart IIII Construction commenced(engine Compression ignition, all sizes ordered)after 7/11/05,engine manufactured after 4/1/06. 40 CFR Part 60 Subpart JJJJ Construction commenced(engine Spark Ignition, all sizes ordered)after 6/12/06, engine manufactured after 7/1/07* *7/1/07 is the earliest manufactured date for which NSPS requirements apply,the manufactured date varies depending on size and type of engine. 2. EPA promulgated National Emission Standards for Hazardous Air Pollutants for Paint Stripping and Miscellaneous Surface Coating Operations at Area Sources (40 CFR Part 63 Subpart HHHHHH) on January 9, 2008. Since the Ft. Lupton Cogeneration Facility is not a major source of hazardous air pollutant(HAP) emissions, these rules potentially apply. The Division believes that any spray coating of motor vehicles and mobile equipment and spray application of coatings that contain target HAPS that may occur at this facility would meet the definition of facility maintenance and would therefore, not be subject to the requirements in 40 CFR Part 63 Subpart HHHHHH. However, we cannot determine whether any paint stripping activities at this facility would be subject to these requirements. Please indicate whether any paint stripping chemicals used at your facility include methylene chloride. We would like you to review this permit and respond to the items identified above by September 9, 2010. Feel free to call me at (303) 692-3267 if you have any further questions.
