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 tpy7 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? 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-specifc 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. 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 acontrol 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 the Giliham 18Y- 202 well. This well is one of the ten drilled at this facility and there were no significant changes to the facility since the dwelopment of the emissions factors. As a result, the 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 temperature and pressurein 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 (MM Btu/ yr) _ [Uncontrolled VOC (ton/yr)j * [2000(lb/ton)] +MW (lb/lbmol) + [379.41(scf/lbmol)]. [i/VOC mol96] • [Heat Content (Btu/scf)] •�[1MMBtu/(1000;000 Btu)]. The values used in the equation were obtained from a ProMax simulation used to calculate emissiona and develop emission facto-. The values used are as follow: (i) Molecular weight: 45.71b/lbmol, (ii) VOC 69.2%, (lid Heat Content: 2565.48tu/scf.... 3. Pilot Light. Emissions Calculations Operator assumed pilotfuel to have the same conditions of field gas which is consistent with the plant design provide by operator. The permit will not contain initial or periodic ' opacity testing for the enclosed combustor(s)because the 0&M plan approved for this source requires weekly visible emrssronsobservations of the enclosed combustor(s) A throughput limit is includedin the permit for pilot combustion. Emission factors and calculation methods for pilot light c ombustjon emissions are also included In the notes to permit holder. This.. information is included in the permit because pilot light emissions contribute to the overall emissions from this source. Addtionally it is important to include this information because throughput tracking and emission calculation methods are different than those used to estimate emissions based on the condensate throughput.; This clarity is mportant for accurately quantifying actual emissions at this facility. 4. Operator submitted self -certification on (11/05/2018. Division approved self-cert on 11/07/2018. 5. Permit draft was provided tooperator who had two comments. (I) operatorasked to update the facility name and (ii( operator asked to correct emission factors source used to calculate NOx and CO emissions from combustion device. Both issues were corrected and final permit draft was sent to operator. - Section 09 - SCC Coding and Emissions Factors (For Inventory Use Only) AIRS Point tt 001 Process tt 01 SCC Code Uncontrolled Emissions Pollutant Factor Control% Units PM10 0.01 0 lb/1,000 gallons Condensate throughput PM2.5 0.01 0 lb/1,000 gallons Condensate throughput SOx NEM 0 lb/1,000 gallons Condensate throughput NOx 0.25 0 lb/1,000 gallons Condensate throughput VOC 55.93 95 lb/1,000 gallons Condensate throughput CO 0.52 0 lb/1,000 gallons Condensate throughput Benzene 0.12 95 lb/1,000 gallons Condensate throughput Toluene 0.16 95 lb/1,000 gallons Condensate throughput Ethylbenzene 0.01 95 lb/1,000 gallons Condensate throughput Xylene 0.07 95 lb/1,000 gallons Condensate throughput n -Hexane 1.04- 95 lb/1,000 gallons Condensate throughput 224 7M 0.01 95 lb/1,000 gallons Condensate throughput 5 of KAPA\2018\18WE0042.CP2 Storage Tank Regulatory Analysis Worksheet The regulatory requirements below are determined based on requested emissions.

Incomplete APENs will 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.). See Regulation No. 3, Part A, II.C. for revised APEN requirements. Permit Number: 18WE0042 AIRS ID Number: 123 / 9F8B /001 Section 1 - Administrative Information Company Name': PDC Energy, Inc.
