If yes, are the uncontrolled actual or requested emissions for a crude oil tank estimated to be greater than or equal to 20 tons VOC per year OR are the uncontrolled actual or requested emissions for a condensate storage tank estimated to be greater than or equal to 80 tpy? If yes, the permit will contain an "Initial Compliance" testing requirement to develop asite specific emissions factor based on guidelines in PS Memo 14-03. Does the company use a site specific emissions factor to estimate emissions? Ryes and if there are flash emissions, are the emissions factors -based on a pressurized liquid sample drawn at the facility being permitted (forproduced water tanks, a pressurize liquid sample must be analyzed using flash liberation analysis)? This sample should be considered representative which generally means site -specific and collected within one year of the application received date. However, if the facility has not been modified (e.g., no new wells brought on-line), then. it may he appropriate to use an older site -specific sample. If no, the permit will contain an "Initial Compliance" testing requirement to develop a site specific emissions factor based on guideline Does the company request a control device efficiency greater than 95% for a flare or combustion device? If yes, the permit will contain initial and periodic compliance testing in accordance with PS Memo 20-02 Section 08 -Technical Analysis Notes 1. Ste specific Emission Factors The site specific sample used to establish emissions factors for this "source was obtained within a year of the first issuance application. The sample was obtained from the Klein 19u- 202well. This well isone of the eight (8)wails whose liquids are directed to this facility and there were no significant changs to the facility since the development of the emissions factors. As a result, the permit will t require initial testing in order to obtain a new site specific sarn le. it should be noted that the sample includes sampleprobe temperature and pressure in conjunction With gauge pressure and temperature. dary Emissions Calculations: 2.1 Operator used the following equation to calculate the annual heat input -,.welt (MMBtu/yr)= [Uncontrolled VOC(ton/yr)]>[2000(ib/ton}] MW(lb/lbmol)+[37441(sc//Ib.71)]=[t/VOCmot %]=[Heat Content (Bt iscr)]s-j1M'�9Btu/(1000, 000 Bb 11.:'..

The permit w ii not containinitial or periodic -j opacity testing for the enclosed combustor(s)because the O&M plan. approved for thisource requires weekly visible emissionsobsevations of the enclosed combustor(s). Athroughput limit is included in the permit fw pilot combustion. Emission factors and calculation methodsfor pilot light combustion emissions are also included in thenotes to, permit holder. This tnformationis included in the permit because pilot light emissions contribute to the over all emasion front source. Additionally it is important to include this information becrose throughput tracking and emisson calculation methods are different than those used to mate emissions based on the condensate throughput. This. clarity is important for accurately quantifying actual .mt.sionsat this facility. U if certification received on 0`0/05/2618 and approved on 06/07/2018.

If yes, the permit will contain an "Initial Compliance" testing requirement to develop a site specific emissions factor based on guidelines in PS Memo 14-03. Does the company use a site specific emissions factor to estimate emissions? a75!:i..• - If yes and if there are flash emissions, are the emissions factors based on a pressurized liquid sample drawn at the facility being permitted (for produced water tanks, a pressurize liquid sample must be analyzed using flash liberation analysis)? This sample should be considered representative which generally means site -specific and collected within one year of the application received date. However, if the facility has not been modified (e.g., no new wells brought on-line), then it may be appropriate to use an older site -specific sample.�yts If no, the permit will contain an "Initial Compliance" testing requirement to develop a site specific emissions factor based on guidelines in PS Memo 14-03. Does the company request a control device efficiency greater than 95% for a flare or combustion device? If yes, the permit will contain initial and periodic compliance testing in accordance with PS Memo 20-02 Section 08 -Technical Analysis Notes 1. Site -specific Emission Factors: The site specific sample used to establish emissions factors for this source was obtained within a year of the first issuance application. The sample was obtained from thelosephine 19M-234well. This well isone of the thirteen (13) wells drilled at this facility and there were no signifiant changes to the facility since the development of the emissions factors. Asa result, they permit will not require _ initial testing in order to obtain a new site specific sample. It should be noted that the sample includes sample probe tempeature and pressure in conjunction with gauge pressure and temperature. 2. Secondary Emissions Calculations: 2.1 Operator used the following equation to calculate the annual heat input. ` Heat Input (MMHtu/yr) _ [Uncontrolled VOC (ton/yr)] e [2000(tb/ton)] _ MW (lb/lbmol) « [379.41(sof/lbmol)] s [1/VOCmoI %] . [Heat Con tent (Btu/scf)] • [1MMBtu/(1000,000 Btu)]. The values used in the equation were obtained from a Pro Max simulation used to calculate emissions and to develop emission futon The values used are as follow:.(i) Molecular weight: 45.31b/Ib-mol, (ii) VOC mol %: 67.3 %, (Iii) Heat Content:. 2540.6 Btu/scf. 3. Pilot Light Emissions Calculations: Operator assumed pilot fuel to have the same conditions of field gas which is consistent with the plant design provide by o perator. The permit will not contain initial or periodic opacity testing for the enclosed combustors) because the 0&M plan approved for this source requires weekly visible emissionsobservations of the enclosed combustor(s). 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 thenotes to permit holder. This information is included in the permit because pilot light emissions contribute to the overall emissions from this source.Additionally It is important to. include this information became throughput tracking and emission calculation methods are different than those used to estimate emissions based on the condensate throughput. This clarity is important for accurately quantifying actual emissionsat this facility. 4. Self -certification submittal and approval: Self -certification was. submitted by operator on 02/18/2020. The Division approved self -certification on 03/18/2020: _ 5. Operator expressed concerns about rounding issues related to the VOC emissions limit. VOC requested emissions limit is11:84593 tpy, which when rounded to three significant figures as ltisthe. Division's practice, VOC requested limit is 118. tray. Operator expressed that they are concerned that the point source might be out of complicanceif emission were to be 1182 tpy (e.g.); therefore, permit limit forVOC will be rounded up to 11.9 tpy.

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.). See Regulation No. 3, Part A, II.C. for revised APEN requirements. Permit Number: 17WE0552 AIRS ID Number: 123 / 9F2B /001 Section 1 - Administrative Information Company Name': PDC Energy, Inc.
