The site specific VOC and HAP emission factors in the table above are based on a site specific pressurized liquid sample and ProMax simulation. The site specific sample used in the ProMax simulation was obtained from the outlet of the high pressure side of the high/low pressure separator for the Billings 3A-18H L368 well on 12/20/2019. The sample pressure and temperature are 144.5 psig and 80°F respectively. The AP-42 Chapter 13.5 CO emission factor (0.31 lb/MMBtu) in the table above was converted to units of lb/bbl using a gas-to-oil ratio (GOR) of 64.9 scf/bbl and a heat content of 2657.02 Btu/scf.

Actual emissions are calculated by multiplying the emission factors in the table above by the total fuel flow of the pilot light gas. Pilot light gas fuel flow is based on a constant rate of 25 scf/hr. Monthly pilot light gas throughput shall be determined by multiplying this hourly pilot gas throughput by the enclosed combustor monthly hours of operation. There is one (1) enclosed combustor equipped with a single pilot light used to control emissions from the condensate storage vessels. Total actual emissions are obtained from the sum of emissions resulting from the storage vessels and combustion of waste gas from the storage vessels (process 01) and the combustion of pilot light gas (process 02). 6) In accordance with C.R.S. 25-7-114.1, each Air Pollutant Emission Notice (APEN) associated with this permit is valid for a term of five years from the date it was received by the Division. A revised APEN must be submitted no later than 30 days before the five-year term expires. Please refer to the most recent annual fee invoice to determine the APEN expiration date for each emissions point associated with this permit. For any questions regarding a specific expiration date call the Division at (303)-692-3150. 7) This permit fulfills the requirement to hold a valid permit reflecting the storage tank and associated control device per the Colorado Oil and Gas Conservation Commission rule 805b(2)(A) when applicable.

The site specific emission factors for this source were developed using flash liberation analysis and EPA Tanks 4.0.9d. The flash liberation analysis is based on a pressurized produced water sample was obtained from the outlet of the high/low pressure separator for the Billings 3F- Page 8 of 10 COLORADO "' Air Pollution Control Division CDPHE Det..NEfirrrent t'Putb_tfealtri&Envvuvtie•,t Dedicated to protecting and improving the health and environment of the people of Colorado 18H L368 well on August 15,2019.The sample temperature and pressure are 116'F and 22.8 psig respectively. The sample was flashed to ambient conditions of 12.2 psia and 72°F. The weight%values, molecular weight (30.4299 lb/lbmol) and gas-to-water ratio (2.9 scf/bbl) established through the flash liberation analysis are used in conjunction with the EPA Emission Inventory Improvement Program Publication: Volume II, Chapter 10 - Displacement Equation (10.4-3) to calculate the flash portion of the emission factors. The working and breathing portion of the emission factors were developed using EPA Tanks 4.0.9d. The simulation uses Denver for the location basis and a mixture of 95%water and 5%gasoline RVP 13 for the liquid basis. The simulation assumes 1/8 of the total throughput flows through each of the storage vessels.Actual emissions are calculated by multiplying the emission factors in the table above by the total produced water throughput. 6) In accordance with C.R.S. 25-7-114.1, each Air Pollutant Emission Notice (APEN) associated with this permit is valid for a term of five years from the date it was received by the Division. A revised APEN must be submitted no later than 30 days before the five-year term expires. Please refer to the most recent annual fee invoice to determine the APEN expiration date for each emissions point associated with this permit. For any questions regarding a specific expiration date call the Division at (303)-692-3150. 7) This permit fulfills the requirement to hold a valid permit reflecting the storage tank and associated control device per the Colorado Oil and Gas Conservation Commission rule 805b(2)(A) when applicable. 8) This facility is classified as follows: Applicable Status Requirement Operating Permit Synthetic Minor Source of: VOC, NOx Et n-Hexane PSD Synthetic Minor Source of: VOC NANSR Synthetic Minor Source of: VOC, NOx 9) Full text of the Title 40, Protection of Environment Electronic Code of Federal Regulations can be found at the website listed below: http://www.ecfr.gov/ Part 60: Standards of Performance for New Stationary Sources NSPS 60.1-End Subpart A - Subpart UUUU NSPS Part 60, Appendixes Appendix A - Appendix I Part 63: National Emission Standards for Hazardous Air Pollutants for Source Categories MACT 63.1-63.599 Subpart A - Subpart Z MACT 63.600-63.1199 Subpart AA - Subpart DDD MACT 63.1200-63.1439 Subpart EEE - Subpart PPP MACT 63.1440-63.6175 Subpart QQQ- Subpart YYYY MACT 63.6580-63.8830 Subpart ZZZZ - Subpart MMMMM Page 9 of 10 a ,. , coLORADO Air Pollution Control Division C©PHE I C .t3fttnent c,+Pubis-. b_twviruvne^;*, Dedicated to protecting and improving the health and environment of the people of Colorado MACT 63.8980-End Subpart NNNNN - Subpart XXXXXX Page 10 of 10 -�µ--x- COLORADO Air Pollution Control Division r©PHE DEvs 1rne,e o Pubis_Heakh b Env ,,ru le-a Dedicated to protecting and improving the health and environment of the people of Colorado CONSTRUCTION PERMIT Permit number: 20WE0274 Issuance: 1 Date issued: Issued to: Crestone Peak Resources Operating, LLC Facility Name: Billings 18H Battery Plant AIRS ID: 123/9D6B Physical Location: SWNW Section 18 T3N R68W County: Weld County Description: Well Production Facility Equipment or activity subject to this permit: Equipment AIRS Equipment Description Emissions Control ID Point Description Flaring of natural gas vented from the low pressure side of sixteen (16) high/low Buffer 025 pressure (HLP) separators and routed Enclosed through the buffer house during vapor Combustor(s) recovery unit (VRU) downtime.

The VOC and HAP emission factors listed above are based on a site specific extended gas analysis obtained from the outlet of the buffer house (liquids knockout for low pressure gas vented from the low pressure side of the HLP separators) on 02/09/2018. The weight%values and molecular weight (36.4943 lb/lbmol) from the sample along with the displacement equation (EPA Emission Inventory Improvement Publication: Volume II, Chapter 10) were used to determine the emission factors. The CO emission factor listed in the table above was obtained by multiplying the AP-42 Chapter 13.5 CO emission factor (0.31 lb/MMBtu) by a higher heating value of 2,075.4907 Btu/scf. Actual emissions are calculated by multiplying the emission factors in the table above by the total metered low pressure gas vented from the low pressure side of the HLP separators and routed through the buffer house to the enclosed combustor(s). Process 02: Combustion of pilot light gas Uncontrolled Controlled CAS # Pollutant Emission Emission Source Factors Factors (lb/MMSCF) (Ib/MMSCF) CO 310.0 310.0 AP-42 Chapter 13.5 Note: The CO emission factor listed in the table above was obtained by multiplying the AP-42 Chapter 13.5 CO emission factor (0.31 lb/MMBtu) by a heat value of 1,000 Btu/scf. Actual emissions are calculated by multiplying the emission factors in the table above by the total fuel flow of the pilot light gas. Pilot light gas fuel flow is based on a constant rate of 25 scf/hr. Monthly pilot light gas throughput shall be determined by multiplying this hourly pilot gas throughput by the enclosed combustor monthly hours of operation. There is one (1) enclosed combustor equipped with a single pilot light used to control emissions from the low pressure side of the high/low pressure separators. Total actual emissions are obtained from the sum of emissions resulting from the natural gas vented from the low pressure side of the HLP separators and routed through the buffer house to the enclosed combustor(s) (process 01) and the combustion of pilot light gas (process 02).

IVZ Section 08-Technical Analysis Notes I.According to the application,sx en(161 wells produce.this facility The names and API numbers of the wells are available for reference on the condensate storage vessel APEN submitted on 02/05/2020,Accordingta COGCC data, the wells at this facility were fractured between lune and July 2010 and January and February 2015.The wells began production In September 2014 and March 2018 Eight(8)wells produce from the Niobrara fomao'on,two(2)produce from the CodeJFFortllays ibrmagod£.one(1)Produces from the Carlile-Cogell Fort Hays formations,two(2)produce fromthe Niobrara-Fort Hays-Codell formations,two(2)produce horn the CodellCarille formations and one(1) produces from the Niobrarafortliays.Edell-Carlile formations Since the wells began production after 06/05/2016 the separators covered by this point are subject to Regulation 7,Part D,Section lIP. 2.The extended gas analysis used to establish emission factors In this application was obtained from the outlet of the buffer house(liquids knockout for low pressure gas vented from the low pressure side of the HIP separators)at this facility.Asa result,it is representative of only low pressure gas that is vented toand controlled by the enclosed combustors.Additionally the sample was obtained in February2018.Since this sample is site specific and was obtained after all the wells began producing at this faclity,'rtwoe deemed acceptable for estabfishiog emission factors without the need for initial sampling.It should be further anted that no new wells have been added no the facility and the existing welts at the fadlity have not been refixctured since the sample was obtained.Thisfurther supports the removal of initial samplingto confirm the accuracy of the emission factors. 3.This source.controlled by one oane Gmted enclosed combustor.In other words,the enclosed combustor used for...ince does not control emissima from any ocher emissions source adds facility.As a result,the pilot light emissions associated with the dedicated enclosed combustor are evaluated in this analysis. 4.80x emissions from this source are below APEN reporting thresholds.Asa result,limits and emission factors are not included in the permit for NOic 5.According to the operator,aVow meter is installed and operational at this facility.This flow meter only measures the low pressure separator gas vented from the low pressure side of the HLP separators and routed through the buffer h seta the enclosed combustors. B.During normal operations,low pressure gas vented from the low pressure side of the HLP separators is captured using vapor recovery units(lRUs)and r utedto the sales line.During VRU downtime,the low pressure gas Is routed through the buffer house(liquids knockout)and then to the enclosed combustors The flow meter Installed althis facilityFs downstream of the VRU and only measures the volume of low pressure gas routed to the enclosed wmbustor(s). Asa resort,VRU downtime tracking is not required in the permitto verify the volume of gas vented from the separators and rooted to the enclmed combustor(s). 7.Initial and periodicuslble emissions checks for the control device are addressed by the O&M plan.Asa result the permit does not contain Initial or periodic oparitytasting e.Benzene and n-Hexane arethe only reportable HAPs.Asa result,they are Meanly HAPs for which emission factors are included in the permit 9.A throughput limit is Included in the permit for pilot combustion.Emission factors and calculation methods for pilot light combustion emissions are also included in the notes.permit holder.The information h included in the permit because pilot light emissions contribute.the overall emissions from this source.Additionally It Is Important to includethis information because throughput tracking and emission calculation methods are different than those used to estimate emissions based on the low pressure separator waste gas throughput Th larity is important far esuratelygtrandfying actual emlsslore at this fadlity. Be.it should be noted that cosyon factor for VOC associated with pilot light combustion Is not incorporated into the permit.This is due to the fact that the pilot light only results in a negligible contribution of VOC(0.001 toy).This imal amount of emissions does rot irnpaor site total VOC l mdfor this source and therefore can be Ignored. 31.The operator was provided with adraft permit and APEN redline.renew prior to public comment The operator redewed both documents and provided comments.The comments prodded by the operator and the Division's responses are available for referencelnthe email documentation uploaded to records manager for this project section 09-SCC Coding and Emissions Factors(For inventory use only) AIRS P.M.
