Alternative Operating Scenarios The following Alternative Operating Scenario (AOS) for temporary and permanent engine 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, and has been found to meet all applicable substantive and procedural requirements. This permit incorporates and shall be considered a construction permit for any engine replacement performed in accordance with this AOS, and the permittee shall be allowed to perform such engine replacement without applying for a revision to this permit or obtaining a new Construction Permit. 1.1 Engine Replacement The following AOS is incorporated into this permit in order to deal with a compressor engine breakdown or periodic routine maintenance and repair of an existing onsite engine that requires the use of either a temporary or permanent replacement engine. 'Temporary" is defined as In the same service for 90 operating days or less in any 12 month period. "Permanent" is defined as in the same service for more than 90 days In any 12 month period. The 90 days is the total number of days that the engine is in operation. If the engine operates only part of a day, that day counts towards the 90 day total. Note that the compliance demonstrations and any periodic monitoring required by this AOS are in addition to any compliance demonstrations or periodic monitoring required by the permit. All replacement engines are subject to all federally applicable and state -only requirements set forth in this permit (including monitoring and record keeping). Results of all tests and the associated calculations pursuant required by this AOS shall be submitted to the Division within 30 calendar days of the test. Results of all tests shall be kept on site for five (5) years and made available to the Division upon request. The permittee shall maintain a log on-site, or at a local field office with site responsibility, to contemporaneously record the start and stop date of any engine replacement, the manufacturer, model number, horsepower, and serial number of the engine(s) that are replaced during the term of this permit, and the manufacturer, model number, horsepower, and serial number of the replacement engine. 1.1.1 The permittee may temporarily replace the existing compressor engine that is subject to the emission limits set forth in this permit with an engine that is of the same manufacturer, model, and horsepower or a different manufacturer, model, or horsepower as the existing engine without modifying this permit, so long as the emissions from the temporary replacement engine comply with the emission limitations for the existing permitted engine as determined in section 1.2. Measurement of emissions from the temporary replacement engine shall be made as set forth In section 1.2. 1.1.2 The permittee may permanently replace the existing compressor engine that Is subject to the emission limits set forth in this permit with an engine that is of the same manufacturer, model, and horsepower without modifying this pennit, so long as the emissions from the permanent replacement engine comply with the emission limitations for the existing permitted engine as determined in section 1.2, Measurement of emissions from the temporary replacement engine shall be made as set forth in section 1.2. An Air Pollution Emissions Notice (APEN) that includes the specific manufacturer, model and serial number and horsepower of the permanent replacement engine shall be filed with the Division for the permanent replacement engine within 14 calendar days of commencing operation of the replacement engine. The APEN shall be accompanied by the appropriate APEN filing fee and a cover letter explaining that the permittee is exercising an alternative operating scenario and is installing a permanent replacement engine. This AOS cannot be used for permanent engine replacement of a grandfathered or permit 'exempt engine or an engine that Is not subject to emission limits. The permittee shall agree to pay fees based on the normal permit processing rate for review of information submitted to theDivlslon in regard to any permanent engine replacement. If 40 CFR Part 63, Subpart ZZZZ is newly triggered by a permanent replacement engine, the permittee must apply fora revision to their operating permit within 90 days of installation. AIRS ID: To Be Issued 7 Williams Production RMT Company Colorado Department of Public Health and Environment Permit No: To Be Issued INITIAL APPROVAL DRAFT PERMIT 1.2 Portable Analyzer Testing The permittee shall measure nitrogen oxide (NO.) and carbon monoxide (CO) emissions in the exhaust from the replacement engine using a portable flue gas analyzer within seven (7) calendar days of commencing operation of the temporary replacement engine. • All portable analyzer testing required by this permit shall be conducted using the Division's Portable Analyzer Monitoring Protocol as found on the Division's website at: http://www.cdohe.state co us/ao/down/oortanalyzeproto.pdf Results of the portable analyzer tests shall be used to monitor the compliance status of this unit. For comparison with an annual or short term emission limit, the results of the tests shall be covered to a Ib/hr basis and multiplied by the allowable operating hours in the month or year (whichever applies) in order to monitor compliance. If a source is not limited in its hours of operation the test results will be multiplied by the maximum number of hours in the month or year (8760), whichever applies. If the portable analyzer results Indicate compliance with both the NOx and CO emission limitations, in the absence of credible evidence to the contrary, the source may certify that the engine is in compliance with both the NOX and CO emission limitations for the relevant time period. Subject to the provisions of C.R.S. 25-7-123.1 and in the absence of credible evidence to the contrary, if the portable analyzer results fail to demonstrate compliance with either the NOx or CO emission limitations, the engine will be considered to be out of compliance from the date of the portable analyzer lest until a portable analyzer test indicates compliance with both the NOx and CO emission limitations or until the engine is taken offline. 1.3 Additional Sources The replacement of an existing engine with a new engine 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; an engine that is being installed as an entirely new emission point and not as part of an AOS -approved replacement of an existing ensile engine has to go through the appropriate Construction/Operating permitting process prior to installation.

Permit Number: Pending Background The proposed Rabbit Brush Compressor Station generator engine (ID: ENG -5) meets the applicability requirements as described in 40 CFR 64 Compliance Assurance Monitoring (CAM). • The unit will be located at a proposed major source; • The unit is subject to emission limitations or standards for an applicable regulated air pollutant; • The emission unit will use an add-on control device to achieve compliance with an emission limit; and • The emission unit has a potential to emit without the control device of greater than 100 tons per year of NOx. The CAM regulation requires the following of an affected source: • Proposed indicators of performance relevant to compliance; • Indicator ranges or conditions, or the process by which such indicators will be established; • Performance criteria that satisfy 40 CFR 64.3(b); • Indicator ranges and performance criteria. The regulation requires affected sources to monitor at least one indicator of performance for the control device. For these sources a minimum of one observation per 24 hours of the chosen parameter must be performed and recorded. Rationale of Selection of Performance Indicators The pressure drop across the catalyst is monitored weekly. AAP exceeding limits in indicator range may indicate that the catalyst is becoming fouled. Temperature into the unit is measured because temperature excursions can indicate problems with engine operation and can retard the chemical reduction taking place in the catalyst bed.

UMORATTON 8c PRODUCTION Tower 3, Suite 1000 1515 Anphoe Stint Dans CO 80202 303/572-3903 303/629.8282 &z Williams Production RMT Company (Williams) is submitting the attached Facility -Wide Construction Permit Application for a proposed natural gas compression facility, the Rabbit Brush Compressor Station. The Rabbit Brush Compressor Station (Rabbit Brush) will be located in the NW % of the SE '4 of Section 32, Township 6S, Range 95W in Garfield County, situated at an elevation of approximately 5155 ft above sea level. This facility is designed with a capacity to gather and compress up to 180 MMacf/day of incoming natural gas at a typical field pressure of 200-245 psig. Inlet field natural gas will be routed through an inlet separator to rove entrained liquids from the inlet gas stream. The gas will be compressed by several reciprocating, interval combustion engine -driven compressors to a pressure of approximately 900-950 psig, and routed through two parallel triethylene glycol (TEG) dehydration units to remove moisture from the gas stream. The dehydrated natural gas stream will then Ieave the facility via pipeline. Williams plans to instal four inteamal combustion engine driven compressors, one internal combustion engine driven generator, one process heater, two 90 MMscflday TEG dehydration units, one vapor recovery unit (VRU), and three 400 -bbl condensate storage tanks at the facility. A site location map, facility plot plan, and process flow diagrams are provided in Attachment 1. A completed Permit Application form and completed APENs for emissions sources are provided in Attachment 2. FacfHty-Wlde So{utc8 and .nilnlon: Internal Combustion-} noires There will be five (5) natural gas fired reciprocating internal combustion engines at the Rabbit Brush Compressor Station. There will be four Caterpillar 3612LE TA -130 4 - cycle lean burn engines each site -rated at 3,550 hp and equipped with selective catalytic oxidation (SCO) mission control systems that will operate in inlet natural gas compression service (source ID: ENG -01 through ENG -04). Site -rated horsepower ratings are based on non -derated manufacturer specifications. The NOJCONOC E Roland Hes - CDPHE Ouober 31, 2006 Page 2 emission factors for these engines will be 0.7 g/hphr NO., 0.18 g/hp-br CO, and 0.1 g/hp- hr VOC based on ms's emission factors and emission testing malts obtained for like -kind engines operating at the Williams Parachute Crede Gas Plant. The annual potential emissions of NO., CO, and VOC from each engine will be 24.0 tpy, 6.0 tpy, and 3.4 tpy. The fifth engine will be a Catapillar G3516 TALE generator engine site -rated at 1,053 hp (1,200 rpm), also equipped with an SCO emission control system that will provide backup electrical power to the site. This unit will be permitted at mniminn operational capacity of 8,760 hra/year based on non -derated manufacturer specifications. The NO./CO/VOC emission factors for this proposed controlled engine will be 1.510.5/0.5 g/hp-hr with maximum annual NO., CO, and VOC emissions of 15.3 tpy, 5.1 tpy, and 5.1 tln . Triethvlene GlvcoLDdrvdration.Iinits.,,,a„- There will be two TEO dehydration units (Source ID: DEHY-1 and DEHY-2), plumbed in parallel, and each designed to remove water from the natural gas after it has been compressed to 900-950 psig by the booster compression units. Each TEG dehy is designed to process up to 90 MMscflday of field natural gas and both will operate with a flash tank and a regenerator still vent condenser emission control. Under normal operating conditions, the flash tank ovabead vapor streams and the regenerator still vent condense' overhead streams from both TEG dehydration units will be routed to the VRU. The dehydration units therefore are designed to operate as closed- loop systems with no emissions to ahnosphers. Consistent with Division recommendations, Williams is classifying the VRU as a control device rather than a permitted process unit, and is listing the VRU as such on the completed APEN forms for the two dehydration units. HYBON Engineering, the proposed VRU manufacturer, guarantees a minimum 95% runtime, which corresponds to a maximum of 18 days of down-time per year for routine repair and maintenance. The control efficiency of each dehy, as listed on the APENs, was ddmnined based on the VRU vendor run-time patentee, a copy of which is provided in Attachment 3. Controlled emissions listed on the dehydration unit APENs were calculated based on the assumption that each dehydration unit operates with condenser controls at all times and a VRU downtime of 5%. When the VRU is not operating, VOC and 11AP are emitted from the flash tank and the regenerator still vent condenser outlet of each dehydration unit. The estimated annual permitted VOC emissions from each dehydration unit are 3.6 tpy from each flash tank and 4.8 tpy from each regenerator still vent condenser outlet, for a total of 8.4 tpy for each dehydration unit. L Roland Ha - CDPHE October 31, 2006 Page 3 Condensate Stmaowa. Williams plans to install three 400 -bbl aboveground atmospheic condensate storage tanks. The three stock tanks (ID: TANK -01) will be manifoldcd together and will be designated as one emission point. Condensate at a maximum inlet pressure of approximately 245 prig will be routed from the inlet gas separator to a pressurized condensate flash tank process vessel which will operate at approximately 20 psig. Condensate flash vapors produced as the condensate pressure is reduced from the inlet separator pressure to 20 psig am routed to the VRU whew they are reoompressed and muted back into the facility inlet gas stream with zero emissions to atmosphere. Additional dash gas is produced as the 20 psig condensate leaves the flash tank process vessel and is routed to the stock tanks operating at atmospheric press' e. This flash gas will be emitted through the TANK -01 vents to atmosphere. A process flow diagram of the VRU is presented is Attachment 1; Permitted VOC emissions from the TANK -01 emission source are calculated as the combined total of estimated flash and working/hreathing emissions from the tanks during normal operating conditions with the VRU operating (dash from 20 prig to atmosphere, 8,322 fir/yr), phis estimated flash and working/breathing emissions during VRU down- time (flash from 245 psig to atmosphere, 438 hr/yr). An average daily condensate production rate of 40 bbl/day is assumed. Annual VOC emissions from the TANK -01 emission source during normal operating conditions, estimated using the API E&P TANKS 2.0 computer model and including flash and working/breathing Iosses, aro 15.0 tpy. Annual VOC_emissions from the TANK -01 emission source during upset conditions when the VRU is not operating are estimated at 2.5 tpy. Total requested VOC emissions from the TANK -01 emission source am 17.5 tpy. The calculated overall control efficiency for the VRU in controlling all potential VOC emissions from the TANK -01 emission source is 65%. Consistent with Division recommendations, Williams is classifying the VRU as a control device rather than a permitted process unit, and is listing the VRU as such on the completed APEN for the TANK -01 emission source. Due to the inherent seasonal variability of condensate production in the Piceance Basin, Williams requests that APCD lists only an annual condensate throughput limit in the permit. Vapor Recovery UAL As described above, Williams will use one VRU as a VOC and HAP emission contuA device for both dehydration units and the condensate tank mission unit. The permitted emissions from the dehydration units and the condensate storage tanks are estimated based on the vendor guarantee of a 95% control efficiency for the vapor streams being controlled by the VRU, based an a 100% control efficiency while operational, and assuming a maximum down-time of 5% (I8 days per year) when the VRU is non- operational. A process flow diagram of the proposed VRU is provided in Attachment 1. Roland Hes - CDPHE October 31, 2006 Page 4 Pions Resor Williams will install a heat medium system that will be used to support various process unit operations including TEG regeneration, building heat, storage tank heating and other miscellaneous heat loads. This natural gas fiord process heater (ID: HTR -01) has a maximum heat rating of 15.0 MMBtu/hr. Emssions of NO., CO, and VOC are estimated at 632 tpy, 531 tpy and 0.35 tpy, based _ Fion AP -42 natural gas combustion emission factors. An equipment specification sheet for this heater is provided in Attachment 3. .rtdput Periodically, condensate will be loaded from the condensate storage tanks at Rabbit Brush into trucks for transport off site (ID: LOAD -01). The estimated total condensate production rate of 40 bbis/day and molecular weight data from the E&P TANKS 2.0 model were used in conjunction with the USEPA loadout equation to estimate VOC emissions from this source. Emissions of VOC from this source are estimated to be below the thresbold limit of 2 tpy for APEN reporting. Therefore, the LOAD -01 condensate loadout source is an insignificant omission source that will not be included in the facility -wide permit. A condensate loadout calculation sheet is provided in Attachment 3. jrunitive VOC from 1 eakinv Pnuipmait Potential fugitive VOC emissions from leaking equipment (ID: FUG -01) are estimated at 7.5 tpy VOC, using estimated equipment component counts, a representative inlet gas analysis from a compressor station in the same field, and US EPA Oil and Gas Production Operations emission factors. A fugitive VOC emissions calculation sheet is provided in Attachment 3. Total Facility -Wide Potential Emissions Total facility -wide potential emissions for all sources included in the facility -wide permit and all sources that are exempt from permitting are 117.6 tpy NO,,, 34.5 tpy CO, and 60.7 tpy VOC at Rabbit Brush. Potential emissions of regulated non -criteria reportable pollutants (HAP) flan the facility are estimated at 14.7 tpy aggregate, with formaldehyde being the highest single HAP emission at 6.0 tpy. An emissions spreadsheet is provided in Attachment 3. Compliance wick National Ambient Mr Quality Stoudards (NAAOSI Williams used the US EPA SCREENS model to demonstrate that the NO, emissions from the five internal combustion ergines at Rabbit Brush will not result in a violation of the annual NAAQS for NO2 of 100 µglm3. The combined maximum annual ambient air NO2 concentration is estimated at 40.0 gghn3 at the nearest property boundary approximately 150 feet from the primary compressor engine building. Adding an Roland Hea- CDPHE October 31, 2006 Page S accepted background NO2 concentration of 7.5 pg/m3, provided by Doris Jung of the APCD, results in a total combined maximum ambient air concatration of 47.5 µg/m3. This value is well blow the annual NAAQS for NO2 of 100 µg/m3 and the proposed facility will not cause an off-site violation of the NAAQS. Copies of the NAAQS calculation sheet and SCREEN3 input and output rcpuit are provided in Attachment 4. We request that the Division invoice Williams for the APEN fees associated with this application.

January 3, 2007 Mr. Roland Hea Colorado Department of Public Health and Environment Air Pollution Control Division, APCD-SSP-B1 4300 Cherry Creek Drive South Denver, CO 80246-1530 Re: Rabbit Brush Compressor Station Revised APENs/Draft Permit Dear Mr. Hea: EXPLORATION & PRODUCTION Tower 3, Suite 1000 1515 Arapahoe Street Denver, CO 80202 303/572-3900 303/629-8282 fax Williams is submitting several revised APENs for the proposed engines at the Rabbit Brush Compressor Station. The original permit application for this facility was delivered to CDPHE in late October 2006. Based on the need for greater operational flexibility, Williams requests that the NQ emission factor for the proposed Caterpillar G3612 TALE -130 engines is increased from 0.7 g/hp-hr to 1.0 g/hp-hr. In addition, the proposed 1,053 hp generator engine to provide backup electric power to this facility is now slated to be a G3516 TA -130 rich -burn engine, equipped with a 3 -way catalyst for controlling NOa, CO and VOC emissions. The generator engine was incorrectly listed as lean -burn unit in the original application submittal. This rich -burn generator engine will be subject to 40 CFR Part 64 Compliance Assurance Monitoring (CAM) and will follow the proposed CAM planattached with this letter to verify that the controls are operating properly. Revised facility -wide emission calculations are attached along with the revised engine APENs. These should replace the original APENs submitted for the proposed engines at the Rabbit Brush Compressor Station. Williams has also attached a proposed draft permit summary to help facilitate CDPHE review and response to this application. If you have any questions related to this submittal please call me at (303) 606-4246 or Rick Matar at (303) 606-4366.

Alternative Operating Scenarios The following Altemative Operating Scenario (AOS) for temporary and permanent engine 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, and has been found to meet all applicable substantive and procedural requirements. This permit incorporates and shall be considered a construction perinitfor any engine replacement performed in accordance with this AOS, and the permittee shall be allowed to perform such engine replacement without applying for a revision to this permit or obtaining a new Construction Permit. 1.1 Engine Replacement The following AOS is incorporated into this permit in order to deal with a compressor engine breakdown or periodic routine maintenance and repair of an existing onsite engine that requires the use of either a temporary or permanent replacement engine. 'Temporary" is defined as in the same service for90 operating days or less in any 12 month period. `Permanent" is defined as in the same service for more than 90 days in any 12 month period. The 90 days is the total number of days that the engine is in operation. If the engine operates only part of a day, that day counts towards the 90 day total. Note that the compliance demonstrations and any periodic monitoring required by this AOS are In addition to any compliance demonstrations or periodic monitoring required by the permit. All replacement engines are subject to all federally applicable and state -only requirements set forth in this permit (Including monitoring and record keeping). Results of all tests and the associated calculations pursuant required by this AOS shall be submitted to the Division within 30 calendar days of the test. Results of all tests shall be kept on site for five (5) years and made available to the Division upon request. The permittee shall maintain a log on-site, or at a local field office with site responsibility, to contemporaneously record the start and stop date of any engine replacement, the manufacturer, model number, horsepower, and serial number of the engine(s) that are replaced during the term of this permit, and the manufacturer, model number, horsepower, and serial number of the replacement engine. 1.1.1 The permittee may temporarily replace the existing compressor engine that is subject to the emission limits set forth in this permit with an engine that is of the same manufacturer, model, and horsepower or a different manufacturer, model, or horsepower as the existing engine without modifying this permit, so long as the emissions from the temporary replacement engine comply with the emission limitations for the existing permitted engine as determined in section 1.2. Measurement of emissions from the temporary replacement engine shall be made as set forth In section 1.2. 1,1.2 The permittee may permanently replace the existing compressor engine that Is subject to the emission limits set forth in this permit with an engine that is of the same manufacturer, model, and horsepower without modifying this permit, so long as the emissions from the permanent replacement engine comply with the emission limitations for the existing permitted engine as determined in section 1.2. Measurement of emissions from the temporary replacement engine shall be made as set forth in section 1.2. An Air Pollution Emissions Notice (APEN) that includes the specific manufacturer, model and serial number and horsepower of the permanent replacement engine shall be filed with the Division for the permanent replacement engine within 14 calendar days of commencing operation of the replacement engine. The APEN shall be accompanied by the appropriate APEN filing fee and a cover letter explaining that the permittee is exercising an atematve operating scenario and is installing a permanent replacement engine. This AOS cannot be used for permanent engine replacement of a grandfathered or permit exempt engine or an engine that is not subject to emission limits. The permittee shall agree to pay fees based on the normal permit processing rate for review of information submitted to the Division in regard to any permanent engine replacement. If 40 CFR Part 63, Subpart ZZZZ is newly triggered by a permanent replacement engine, the permittee must apply fora revision to their operating permit within 90 days of Installation. AIRS ID: To Be Issued 7 Williams Production RMT Company Colorado Department of Public Health and Environment Permit No: To Be Issued INITIAL APPROVAL DRAFT PERMIT 1.2 Portable Analyzer Testing The permittee shall measure nitrogen oxide (N04 and carbon monoxide (CO) emissions in the exhaust from the replacement engine using a portable flue gas analyzer within seven (7) calendar days of commencing operation of the temporary replacement engine. • All portable analyzer testing required by this permit shall be conducted using the Division's Portable Analyzer Monitoring Protocol as found on the Division's website at: htto://www.cdphe.state.co.us/ao/down/portanalvzeproto.odf Results of the portable analyzer tests shall be used to monitor the compliance status of this unit. For comparison with an annual or short term emission limit, the results of the tests shall be covered to a Ib/hr basis and multiplied by the allowable operating hours in the month or year (whichever applies) in order to monitor compliance. If a source is not limited in Its hours of operation the test results will be multiplied by the maximum number of hours In the month or year (8760), whichever applies. If the portable analyzer results indicate compliance with both the NOx and CO emission limitations, In the absence of credible evidence to the contrary, the source may certify that the engine is in compliance with both the NOX and CO emission limitations for the relevant time period. Subject to the provisions of C.R.S. 25-7-123.1 and in the absence of credible evidence to the contrary, if the portable analyzer results fail to demonstrate compliance with either the NOx or CO emission limitations, the engine will be considered to be out of compliance from the date of the portable analyzer test until a portable analyzer test indicates compliance with both the NOx and CO emission limitations or until the engine is taken offline. 1.3 Additional Sources The replacement of an existing engine with a new engine 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; an engine that is being installed as an entirely new emission point and not as part of an AOS -approved replacement of an existing onsite engine has to go through the appropriate Construction/Operating permitting process prior to installation.

Permit Number: Pending Background The proposed Rabbit Brush Compressor Station generator engine (ID: ENG -5) meets the applicability requirements as described in 40 CFR 64 Compliance Assurance Monitoring (CAM). • The unit will be located at a proposed major source; • The unit is subject to emission limitations or standards for an applicable regulated air pollutant; • The emission unit will use an add-on control device to achieve compliance with an emission limit; and • The emission unit has a potential to emit without the control device of greater than 100 tons per year of NO,„ The CAM regulation requires the following of an affected source: • Proposed indicators of performance relevant to compliance; • Indicator ranges or conditions, or the process by which such indicators will be established; • Performance criteria that satisfy 40 CFR 64.3(b); • Indicator ranges and performance criteria. The regulation requires affected sources to monitor at least one indicator of performance for the control device. For these sources a minimum of one observation per 24 hours of the chosen parameter must be performed and recorded. Rationale of Selection of Performance Indicators The pressure drop across the catalyst is monitored weekly. AAP exceeding limits in indicator range may indicate that the catalyst is becoming fouled. Temperature into the unit is measured because temperature excursions can indicate problems with engine operation and can retard the chemical reduction taking place in the catalyst bed. Williams Production RMT Company, Rabbit Brush Compressor Station ENG -5 CAM Plan Submitted January 3, 2007 Monitoring Approach The key elements of the monitoring approach for NO,, emissions, including the indicators to be monitored, indicator ranges and performance criteria are presented in Table 1 below.

Theoriginal permit application for this facility was delivered to CDPHE in late October 2006. Based on the need for greater operational flexibility, Williams requests that the NO, emission factor for the proposed Caterpillar G3612 TALE -130 engines is increased from 0.7 g/hp-hr to 1.0 g/hp-hr. In addition, the proposed 1,053 hp generator engine to provide backup electric power to this facility is now slated to be a 63516 TA -130 rich -burn engine, equipped with a 3 -way catalyst for controlling NO,t, CO and VOC emissions. The generator engine was incorrectly listed as lean -burn unit in the original application submittal. This rich -bum generator engine will be subject to 40 CFR Part 64 Compliance Assurance Monitoring (CAM) and will follow the proposed CAM plan attached with this letter to verify that the controls are operating properly. Revised facility -wide emission calculations are attached along with the revised engine APENs. These should replace the original APENs submitted for the proposed engines at the Webster Hill Compressor Station. Williams has also attached a proposed draft permit summary to help facilitate CDPHE review and response to this application. If you have any questions related to this submittal please call me at (303) 606-4246 or Rick Matar at (303) 606-4366.

Alternative Operating Scenarios The following Alternative Operating Scenario (AOS) for temporary and permanent engine 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, and has been found to meet all applicable substantive and procedural requirements. This permit incorporates and shall be considered a construction permit for any engine replacement performed in accordance with this AOS, and the permittee shall be allowed to perform such engine replacement without applying for a revision to this permit or obtaining a new Construction Permit. 1.1 Engine Replacement The following AOS Is incorporated into this permit in order to deal with a compressor engine breakdown or periodic routine maintenance and repair of an existing onsite engine that requires the use of either a temporary or permanent replacement engine. `Temporary' is defined as in the same service for 90 operating days or less in any 12 month period. "Permanent" is defined as in the same service for more than 90 days in any 12 month period. The 90 days is the total number of days that the engine is In operation. If the engine operates only part of a day, that day counts towards the 90 day total. Note that the compliance demonstrations and any periodic monitoring required by this AOS are in addition to any compliance demonstrations or periodic monitoring required by the permit. All replacement engines are subject to all federally applicable and state -only requirements set forth in this permit (including monitoring and record keeping). Results of all tests and the associated calculations pursuant required by this AOS shall be submitted to the Division within 30 calendar days of the test. Results of all tests shall be kept on site for five (5) years and made available to the Division upon request. The permittee shall maintain a log on-site, or at a local field office with site responsibility, to contemporaneously record the start and stop date of any engine replacement, the manufacturer, model number, horsepower, and serial number of the engine(s) that are replaced during the term of this permit, and the manufacturer, model number, horsepower, and serial number of the replacement engine. 1.1.1 The permittee May temporarily replace the existing compressor engine that is subject to the emission limits set forth in this permit with an engine that is of the same manufacturer, model, and horsepower or a different manufacturer, model, or horsepower as the existing engine without modifying this permit, so long as the emissions from the temporary replacement engine comply with the emission limitations for the existing permitted engine as determined in section 1.2. Measurement of emissions from the temporary replacement engine shall be made as set forth in section 1.2. 1.1.2 The permittee may permanently replace the existing compressor engine that is subject to the emission limits set forth in this permit with an engine that is of the same manufacturer, model, and horsepower without modifying this permit, so long as the emissions from the pemranent replacement engine comply with the emission limitations for the existing permitted engine as determined in section 1.2. Measurement of emissions from the temporary replacement engine shall be made as set forth in section 1.2. An Air Pollution Emissions Notice (APEN) that includes the specific manufacturer, model and serial number and horsepower of the permanent replacement engine shall be filed with the Division for the permanent replacement engine within 14 calendar days of commencing operation of the replacement engine. The APEN shall be accompanied by the appropriate APEN filing fee and a cover letter explaining that the permittee is exercising an altemative operating scenario and is installing a permanent replacement engine. This AOS cannot be used for permanent engine replacement of a grandfathered or permit exempt engine or an engine that is not subject to emission limits. The permittee shall agree to pay fees based on the normal permit processing rate for review of infonnationsubmitted to the Division in regard to any permanent engine replacement. If 40 CFR Part 63, Subpart ZZZZ is newly triggered by a permanent replacement engine, the permittee must apply for a revision to their operating permit within 90 days of installation. AIRS ID: To Be Issued 7 Williams Production RMT Company Colorado Department of Public Health and Environment Permit No: To Be Issued INITIAL APPROVAL DRAFT PERMIT 1.2 Portable Analyzer Testing The permittee shall measure nitrogen oxide (NO„) and carbon monoxide (CO) emissions In the exhaust from the replacement engine using a portable flue gas analyzer within seven (7) calendar days of commencing operation of the temporary replacement engine. All portable analyzer testing required by this permit shall be conducted using the Division's Portable Analyzer Monitoring Protocol as found on the Division's website at: http://www.cdr he.state.cp.us/ao/down/oortanalvzeproto.pdf Results of the portable analyzer tests shall be used to monitor the compliance status of this unit. For comparison with an annual or short term emission limit, the results of the tests shall be covered to a Ib/hr basis and multiplied by the allowable operating hours In the month or year (whichever applies) in order to monitor compliance. If a source is not limited in its hours of operation the test results will be multiplied by the maximum number of hours in the month or year (8760), whichever applies. If the portable analyzer results indicate compliance with both the NOx and CO emission limitations, in the absence of credible evidence to the contrary, the source may certify that the engine is in compliance with both the NOX and CO emission limitations for the relevant time period. Subject to the provisions of C.R.S. 25-7-123.1 and in the absence of credible evidence to the contrary, if the portable analyzer results fail to demonstrate compliance with either the NOx or CO emission limitations, the engine will be considered to be out of compliance from the date of the portable analyzer test until a portable analyzer test Indicates compliance with both the NOx and CO emission limitations or until the engine is taken offline. 1.3 Additional Sources The replacement of an existing engine with a new engine is viewed byte 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; an engine that is being installed as an entirely new emission point and not as part of an AOS -approved replacement of an existing onsite engine has to go through the appropriate Construction/Operating permitting process prior to Installation.

Permit Number: Pending Background The proposed Webster Hill Compressor Station generator engine (ID: ENG -5) meets the applicability requirements as described in 40 CFR 64 Compliance Assurance Monitoring (CAM). • The unit will be located at a proposed major source; • The unit is subject to emission limitations or standards for an applicable regulated air pollutant; • The emission unit will use an add-on control device to achieve compliance with an emission limit; and • The emission unit has a potential to emit without the control device of greater than 100 tons per year of NO,E. The CAM regulation requires the following of an affected source: • Proposed indicators of performance relevant to compliance; • Indicator ranges or conditions, or the process by which such indicators will be established; • Performance criteria that satisfy 40 CFR 64.3(b); • Indicator ranges and performance criteria. The regulation requires affected sources to monitor at least one indicator of performance for the control device. For these sources a minimum of one observation per 24 hours of the chosen parameter must be performed and recorded. Rationale of Selection of Performance Indicators The pressure drop across the catalyst is monitored weekly. ADP exceeding limits in indicator range may indicate that the catalyst is becoming fouled. Temperature into the unit is measured because temperature excursions can indicate problems with engine operation and can retard the chemical reduction taking place in the catalyst bed.

EXPLORATION & PRODUCTION Taw 3, Suite 1000 1515 Arapahoe Street Dams, CO 80202 303/572-3900 303/629-8282 rax Williams Production RMT Company (Williams) is submitting the attached Facility -Wide Construction Pennit Application for a new natural gas compression facility called the Webster Hill Compressor Station. The Webster Hill Compressor Station (Webster Hill) will be located in the NW '/4 of' the SW '/4 of Section 14, Township 6S, Range 94W in Garfield County at an elevation of approximately 5,500 ft above mean sea level. This facility is designed with a capacity to gather and compress up to 180 MMsef/day of incoming natural gas at a typical field pressure of 200-245 psig. Inlet field natural gas will be routed through an inlet separator to remove entrained liquids from the inlet gas stream. The gas will be compressed by several reciprocating, internal combustion engine -driven compressors to a pressure of approximately 900-950 psig, and routed through two parallel triethylene glycol (TEG) dehydration units to remove moisture from the gas stream. The dehydrated natural gas stream will then leave the facility via pipeline. Williams plans to install four internal combustion engine driven compressors, one internal combustion engine driven generator, one process heater, two 90 MMscf/day TEG dehydration units, one vapor recovery unit (VRU), and three 400 -bbl condensate storage tanks at the facility. A site location map, facility plot plan, and process flow diagram are provided in Attachment 1. A completed Permit Application form and completed APENs for emissions sources are provided in Attachment 2. Facility -Wide Sources and Emissions Internal Combustion Engines There will be five (5) natural gas fired reciprocating internal combustion engines at the Webster Hill Compressor Station. There will be four Caterpillar 3612LE TA -I30 4 -cycle lean burn engines each site -rated at 3,550 hp and equipped with selective catalytic oxidation (SCO) emission control systems that will operate in inlet natural gas compression service (source ID: ENG -01 through ENG -04). Site -rated horsepower ratings are based on non -derated manufacturer specifications. The NOx/CO/VOC Roland Hea - CDPHE October 31, 2006 Page 2 emission factors for these engines will be 0.7 g/hphr NO„, 0.18 g/hp-br CO, and 0.1 g/hp- hr VOC based on manufacturer's emission factors and emission testing results obtained for like -kind engines operating at the Williams Parachute Creek Gas Plant. The annual potential emissions of NO„, CO, and VOC from each engine will be 24.0 tpy, 6.0 tpy, and 3.4 tpy. The fifth engine will be a Caterpillar G3516 TALE generator engine site -rated at 1,053 hp (1,200 rpm), also equipped with an SCO emission control system that will provide backup electrical power to the site. This unit will be permitted at maximum operational capacity of 8,760 brs/year based on non -derated manufacturer specifications. The NOx/CO/VOC emission factors for this proposed controlled engine will be 1.5/0.5/0.5 g/hp-hr with maximum annual NO„, CO, and VOC emissions of 15.3 tpy, 5.1 tpy, and 5.1 tpY. Triethvlene Glycol Dehydration Units There will be two TEG dehydration units (Source ID: DEHY-1 and DEHY-2), plumbed in parallel, and each designed to remove water from the natural gas after it has been compressed to 900-950 psig by the booster compression units. Each TEG dehy is designed to process up to 90 MMscf/day of field natural gas and both will operate with a flash tank and a regenerator still vent condenser emission control. Under normal operating conditions, the flash tank overhead vapor streams and the regenerator still vent condenser overhead streams from both TEG dehydration units will be routed to the VRU. The dehydration units therefore are designed to operate as closed- loop systems with no emissions to atmosphere. Consistent with Division recommendations, Williams is classifying the VRU as a control device rather than a permitted process runt, and is listing the VRU as such on the completed APEN forms for the two dehydration units. HYBON Engineering, the proposed VRU manufacturer, guarantees a minimum 95% run-time, which corresponds to a maximum of 18 days of down-time per year for routine repair and maintenance. The control efficiency of each dehy, as listed on the APENs, was determined based on the VRU vendor run-time guarantee, a copy of which is provided in Attachment 3. Controlled emissions listed on the dehydration unit APENs were calculated based on the assumption that each dehydration unit operates with condenser controls at all times and a VRU downtime of 5%. When the VRU is not operating, VOC and HAP are emitted from the flash tank and the regenerator still vent condenser outlet of each dehydration unit. The estimated annual permitted VOC emissions from each dehydration unit are 3.6 tpy from each flash tank and 4.8 tpy from each regenerator still vent condenser outlet, for a total of 8.4 tpy for each dehydration unit. Roland Hea • CDPHR October 31, 2006 Page 3 Condensate Storage Tanks Williams plans to install three 400 -bbl aboveground atmospheric condensate storage tanks. The three stock tanks (ID: TANK -01) will be manifolded together and will be designated as one emission point. Condensate at a maximum inlet pressure of approximately 245 psig will be routed from the inlet gas separator to a pressurized condensate flash tank process vessel which will operate at approximately 20 psig. Condensate flash vapors produced as"the condensate pressure is reduced from the inlet separator pressure to 20 psig are routed to the VRU where they are recompressed and routed back into the facility inlet gas stream with zero emissions to atmosphere. Additional flash gas is produced as the 20 psig condensate leaves the flash tank process vessel and is routed to the stock tanks operating at atmospheric pressure. This flash gas is emitted through the TANK -01 vents to atmosphere. A process flow diagram of the VRU is presented is Attachment 1. Permitted VOC emissions from the TANK -01 emission source are calculated as the combined total of estimated flash and working/breathing emissions from the tanks during normal operating conditions with the VRU operating (flash from 20 psig to atmosphere, 8,322 hr/yr), plus estimated flash and working/breathing emissions during VRU down- time (flash from 245 psig to atmosphere, 438 hr/yr). An average daily condensate production rate of 40 bbl/day is assumed. Annual VOC emissions from the TANK -01 emission source during normal operating conditions, estimated using the API E&P TANKS 2.0 computer model and including flash and working/breathing losses, are 15.0 tpy. Annual VOC emissions from the TANK -01 emission source during upset conditions when the VRU is not operating are estimated at 2.5 tpy. Total requested VOC emissions from the TANK -01 emission source are 17.5 tpy. The calculated overall control efficiency for the VRU in controlling all potential VOC emissions from the TANK -01 emission source is 65%. Consistent with Division recommendations, Williams is classifying the VRU as a control device rather than a permitted process unit, and is listing the VRU as such on the completed APEN form for the TANK -01 emission source. Due to the inherent seasonal variability of condensate production in the Piceance Basin, Williams requests that APCD lists only an annual condensate throughput limit in the permit. Vapor Recovery Unit As described above, Williams will use one VRU as a VOC and HAP emission control device for both dehydration units and the condensate tank emission unit. The permitted emissions from the dehydration units and the condensate storage tanks are estimated based on the vendor guarantee of a 95% control efficiency for the vapor streams being controlled by the VRU, based on a 100% control efficiency while operational, and assuming a maximum down-time of' 5% (18 days per year) when the VRU is non- operational. A process flow diagram of the VRU is provided in Attachment 1. Roland Ilea - COMM October 31, 2006 Page 4 Process Heater Williams will install a heat medium system that will be used to support various process unit operations including TEG regeneration, building heat, storage tank heating and other miscellaneous heat loads. This natural gas fired process heater (ID: HTR -01) has a maximum heat rating of 15.0 MMBtu/hr. Emissions of NO„ CO, and VOC are estimated at 6.32 tpy, 5.31 tpy and 0.35 tpy, based on AP -42 natural gas combustion emission factors. An equipment specification sheet for this heater is provided in Attachment 3. Loadout Periodically, condensate will be loaded from the condensate storage tanks at Webster Hill into trucks for transport off site (ID: LOAD -01). The estimated maximum condensate production rate of 40 bbl per day and molecular weight data from the E&P TANKS 2.0 model were used in conjunction with the USEPA loadout equation to estimate VOC emissions from this source. Emissions of VOC from this source are estimated to be below the threshold limit of 2 tpy for APEN reporting. Therefore, the LOAD -01 condensate loadout source is an insignificant emission source that will not be included in the facility -wide permit. A condensate loadout calculation sheet is provided in Attachment 3. Fugitive VOC from Leaking Equipment Potential fugitive VOC emissions from leaking equipment (ID: FUG -01) are estimated at 7.5 tpy VOC, using estimated equipment component counts, a representative inlet gas analysis from a compressor station in the same field, and US EPA Oil and Gas Production Operations emission factors. A fugitive VOC emissions calculation sheet is provided in Attachment 3. Total Facility -Wide Potential Emissions Total facility -wide potential emissions for all sources included in the facility -wide permit and all sources that are exempt from permitting are 117.6 tpy NOx, 34.5 tpy CO, and 60.7 tpy VOC. Potential emissions of regulated non -criteria reportable pollutants (HAP) from the facility are estimated at 14.7 tpy aggregate, with formaldehyde being the highest single HAP emission at 6.0 tpy. An emissions spreadsheet is provided in Attachment 3. Compliance with National Ambient Air Quality Standards (NAAOS) Williams used the US EPA SCREEN3 model to demonstrate that the NO„ emissions from the five internal combustion engines at Webster Hill will not result in a violation of the annual NAAQS for NO2 of 100 µg/m3. The combined maximum annual ambient air NO2 concentration is estimated at 40.0 µg/m3 at the nearest property boundary approximately 150 feet from the primary compressor engine building. Adding an accepted background NO2 concentration of 7.5 µg/m3, provided by Doris Jung of the APCD, results in a total combined maximum ambient air concentration of 47.5 µg/m3. Roland Ilea • CDPHE October 31, 2006 Page 5 This value is well below the annual NAAQS for NO2 of 100 pg/m3 and the proposed facility will not cause an off-site violation of the NAAQS. Copies of the NAAQS calculation sheet and SCREEN3 input and output report are provided in Attachment 4. We request that the Division invoice Williams for the APEN fees associated with this application.

BOX 4185 MIDLAND, TEXAS 79704 2404 COMMERCE MIDLAND, TEXAS 79703 mm.hybon.com Date: October 11, 2006 Mr. Gerard G. Alberts Williams Company Principal Environmental Specialist 1515 Arapahoe St., Tower 3, Suite 1000 Denver, CO 80202 Mr. Alberts, Per our conversation yesterday, electric drive vapor recovery units have very minimal down time. As a packager of vapor recovery units for over 50 years, as well as a company that maintains over 100 similar slze units in a rental fleet that are often on "run time" contracts, we estimate average run time on Hy -Bon electric drive vapor recovery units to average 95%. This down time percentage assumes that the unit is properly installed and properly maintained. This percentage coincides with the "over 95%" quoted in an article we had published in the American 011 and Gas Reporter (attached — see last sentence in the article). It also matches the figures used by the Natural Gas STAR program. The STAR presentation on vapor recovery states "vapor recovery can capture up to 95% of the gas from the tanks". We can make no assertions as to the run time viability of other manufacturer's equipment — especially in vapor recovery service. Vapor recovery Is a very specialized application that requires a great deal of experience In working with wet gas at very low pressures. Many companies represent that they sell "vapor recovery units" but actually have little or no experience in this niche application — resulting in projects with extremely poor run times capturing gas. However, we are confident in the run time estimates we provide for Hy -Bon equipment, and it's my sincere hope we have an opportunity to work with Williams Company on this project. Best Regards.
