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 three-phase separator for the Snowmass 3N well on 05/08/2018. The sample pressure and temperature are 24.1 psig and 109°F respectively. The TNRCC Flare Emission Guidance (Technical Supplement 4) NOx and CO emission factors (0.138 lb/MMBtu and 0.2755 lb/MMBtu respectively) in the table above were converted to units of lb/bbl using a gas molecular weight of 38 lb/lbmole, a standard molar volume of 379.41 scf/lb-mole, a VOC mole % of 68% and a heat content of 2,000 Btu/scf. Actual emissions are calculated by multiplying the emission factors in the table above by the total condensate throughput.

The VOC emission factor in the table above was obtained by multiplying the AP-42 Chapter 1.4 emission factor by a ratio of 1,136 Btu/scf to 1,020 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 15.6 scf/hr. There are a total of eleven combustors used to control emissions from the condensate storage vessels. As a result, the total pilot light gas fuel flow is 171.6 scf/hr. Monthly pilot light gas throughput shall be determined by multiplying this hourly pilot gas throughput by the monthly hours of operation of the enclosed combustors. 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.

Does the company request a control device efficiency greater than 95%for a flare or combustion device? eyes,the permit will contain initial and periodic compliance testing in accordance with PS Memo 20-02 Section 08-Technical Analysis Notes 1 Typically,the secondary combustion emissions are caculated using the waste gas flow rate and heat content predicted by the model used to establish the sitespecific emissions factors.Based on the ProMax simulation the total waste gas Flow rate was predictedto be 0.0796392 MMscf/day(Flash and W&B gas).Additionally,an average heat content was determined using the heat content of the flash gas stream(2550.67 Btu/scf)and the W&B stream(2611.03 Btu/scf)and thefollowing equations: Average Beat Content:((2550.678tulscfr(0.0691034 MMscf/day)/(0.0796892 MMscf/day(+.[12611,03 Btu/scfl"(0.0105858 MMscf/dsy)/(0.0796892 MMsef/day))=2558.698tu/scf Using this Information,the yearly heat Input of the gas would be calculated as follows:Heat Input(MMBtu/yr)=(0.0796892 Mvlscf/day(a(365 day/year)"[2556.69 MMetu/MMscf)'(319667 bbl/year)/(891038 bbl/year) =26,700,02MMetu/year.Using thisvalue,the NOx and CO emissions would be calculated at 1.84 tpy and 3.68 tpy respectively. The operatortsd the following equation to calculate the annual heat input Heat Input(MMBtu/yr)=[UncontroltedVOC(toe/ye))"[2000 lb/tonl/(M W(ibfb-mol))•[379.41 suf/ib-rnol)'[1/VOCwt%)`(Heat Content (Btu/scfl(5)1MMRtu/1,000,000 Btu).The operator expressed the values for molecular weight,VOCwt%and heat content used inthe equation were developed by evaluating multiple flash gas analyse in ProMax.The operatorfurther expressed that the values are"conservative enough to be used as representative values."The values used inthe equation areas follow.(1)Molecular weight 381b/Ib.mol,Ilil VOCwt%68%,eii)Heat Content:2000 Bm/scf.Usingthese values,the operator calculated a heat input of 19,456.76 MMBtu/ye.Since this value is more conservative than the value calculated above using prescribed methods,h will be used for permitting purposes 2.The see specific sample used to establish emissions factors for this source was obtained within a year of the application used to develop the site specific emisslom factors.The sample was obtained from the outlet of the three-phase separator for the Snowmass 3N well on 05/08/2018.Th6 well is one of the con existing welt that produceto this tank battery.It should be noted that the sample include sample probe temperature and pressure In conjunction with gauge pressure and temperature.According to lab information,thesample probe temperature and pressure are obtained using lab equipment during the sampling process.These values • are expected to be more accuratecomparedto the gauge values and should be used in the simulation used to establish site spaific emission factors. 3.Please reference the APES submitted on 05/21/2020 for a list of the ten new wells at this facility.Thewelh associated with this tank battery were fractured between January and February 2018 and began production between February and March 2018.0ne well produces from the Cadel4Carlge formationsandthe remaining nine wells produce from the Niobrara formatlon.The sample used to establish site specific emission factors was obtained on05/08/2018.Since the sample was obtained after the wells at thetacllity began production,it isacceptablefor establishing site sped emission factors.It should be noted that the existing wells have not been refractured,recompieted or otherwise modified since they began production and no newwelh have been added tathe faulty.As a result,the previously approved emissions factors are acceptable for continued use.This decision Is supported by Section 5.10.of PS Memo 14-03 which provides the following information:"See-specific emission factors can be used for the following length of time For minor and synthetic minorstorage tanks,the silrspecy is emission factor may be used indefinitely." 4.The permit does not contain periodic opacity testing because the approved 0&M plan fort ho source requires periodic visible emhsions observations 5.Emission factors for ethylbenzene and 2,2,4-TMP will not be included in the permit because emhsions are below APES reporting thresholds(i.e.<200 lb/year). 6.The operator provided the following information regarding the 306 LO control tank listed on the facility diagram:"Theuessel on the facility diagram labeled"300661 toContral Tank"Is the knockout tank for the facility's loadaotflore.Vapors from trucklaadeut are first routed to this tank,and then to the flare dedicated to controling loadoutactivities.Any emfssons associated with this took are accounted for by the laodout emissions,it is not normal operation for ANY condensate to enter this tank In the unlikely event liquid condensate occurs within the tank,either from the condensing of vapors or the flooding of the tank truck vapor line due to overfilling,the liquid is immediately transferred froth the knockout tonk to the condensate storage tanks.'Thh Information indicates any potential emhsions associated with this vessel are appropriately accounted for in the application. 7.A throughput limit h included in the permit for plot combustion.Emission factors and calculation methods for pilot light combustion emissions are also included in the notes to permit holder.Ths information Is included in the permit because pilot light emhsions contribute to the overall emissions from this source.Additionally b Important to Include this information because throughput tracking and emission calculation methods are different than those used to estimate emso ions based on the condensate throughput This clarity is important foraccurately quantifying actual emissions at this facility. e.This source's controlled by eleven(11)dedicated enclosed combustors.In other words,the enclosed combustors used for this source do not control emhsions from any other emissions sourceatths facility.Asa result,the pilot light emissions associated with the dedicated enclosed combustors are evaluated in this analysis.- - 9.At this time,initial and parodic sampling is not required at th's facility because permitted facilOy wide VOC emissions are less than 40 tpy. 10.The operator was provided with a draft permit and ADEN redline to review prior to public comment.The operator reviewed both documents and expressed they had no comments.

Incomplete APENs wilt be rejected and will require re-submittal. Your APEN will be rejected if it is filled out incorrectly, is missing information, or lacks payment for the filing fee. The re-submittal will require payment for a new filing fee. This APEN is to be used for tanks that store condensate associated with oil and gas industry operations. If your emission source does not fall into this category, there may be a more specific APEN available for your source(e.g. crude oil storage tanks, produced water storage tanks, hydrocarbon liquid loading, etc.). In addition, the General APEN (Form APCD-200)is available if the specialty APEN options will not satisfy your reporting needs.A list of all available APEN forms and associated addendum forms can be found on the Air Pollution Control Division (APCD) website. This emission notice is valid for five(5)years. Submission of a revised APEN is required 30 days prior to expiration of the five-year term, or when a reportable change is made(significant emissions increase, increase production, new equipment, change in fuel type,etc.).
