The facility also has a power -generation natural gas RICE (point 008, permitted under the GP02). This facility is synthetic minor with respects to NOx, VOC, CO, n -hexane and total HAPs The turbine units were cancelled prior to public comment/permit issuance. Because points 003 and 004 are both routed to the same enclosed combustion device which has requested 98% control eff ciency, these points were combined on a single permit in order to accommodate for specific testing requirements, as the combustion device cannot operate without a certain volume of flow, which would come from both venting streams.

No If yes, are the uncontrolled actual or requested emissions estimated to be greater than or equal to 80 tons VOC per year? No If yes, the permit will contain an "Initial Compliance" testing requirement to develop a site specific emissions factor based on guidelines in PS Memo 05-01. 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? 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 modi'ied (e.g., no new wells brought on-line), then it may be appropriate to use an older site -specific sample. Yes If no, the permit will contain an "Initial Compliance" testing requirement to develop a site specific emissions factor based on guidelines in PS Memo 05-01. Does the company request a control device efficiency greater than 95% for a flare or combustion device? No If yes, the permit will contain and initial compliance test condition to demonstrate the destruction eficiency of the combustion device based on inlet and outlet concentration sampling Section 08 - Technical Analysis Notes Emission factors were validated based on the newly submitted promax simulation data recieved 5/13/2019. The emission factors requested included a buffer (-60%). The values calculated above have <10% from those requested on the APEN, so the permit will reflect the values requested on the APEN. ................... Volume of gas released per barrel noted above was determined based on the flash emissions in the Promax model. The total heat released as calculated by the source was 12,188 MMBTU/yr, which was used to determine the NOx/CO emissions. �IS'I11' gAl�x{ AµNpW� .MiAA .��ai \ `tm F 1 ]fI�1yMyVlpt % Y p% fY_Rd5YKR Y.MRuxX.R 5E1W]fAlti+3,n'.� 1lktx N'J� Ix �x iJ4'%J %4� IIMMM b' �d M I Y xii H < PPYY'' xYYRX .� bt `b� e l < z nst� elt,`xYthr lsl ¢ xw�x�a % Fx xaa� xx kx,'� Y��v�> Wit., Rx�ahr� �xi Section 09 - Inventory SCC Coding and Emissions Factors AIRS Point # 001 Process # 01 SCC Code < Fx <xxxxnxxr ri xxx Yw nKC Ywt%:. ue Uncontrolled Emissions Pollutant Factor Control % Units PM10 0.00 0 lb/1,000 gallons condensate throughput PM2.5 0.00 0 lb/1,000 gallons condensate throughput NOx 0.01 0 lb/1,000 gallons condensate throughput VOC 4.7 95 lb/1,000 gallons condensate throughput CO 0.04 0 Ib/1,000 gallons condensate throughput Benzene 0.01 95 lb/1,000 gallons condensate throughput Toluene 0.01 95 lb/1,000 gallons condensate throughput Ethylbenzene 0.00 95 lb/1,000 gallons condensate throughput Xylene 0.00 95 lb/1,000 gallons condensate throughput n -Hexane 0.09 95 Ib/1,000 gallons condensate throughput 224 TMP 0.00 95 lb/1,000 gallons condensate throughput 3 of 18 K:\PA\2018\18WE0612.CP1 Condensate Tank Regulatory Analysis Worksheet Colorado Re ulation 3 Parts A and B - APEN and Permit Re uirements Source is in the Non Attainment AI L.: ATTAINMENT 1.

This sample should be considered representative which generally means site -specific and collected within one year of the applicat`on 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. See PS Memo 14-03, Questions 5.9 and 5.12 for additional guidance on testing. Yes Does the company request a control device efficiency greater than 95% for a flare or combustion device? Noimist If yes, the permit will contain and initial compliance test condition to demonstrate the destruction efficiency of the combustion device based on inlet and outlet concentration sampling Section 08 - Technical Analysis Notes Emission factors for the produced water tank were based on a Flashed Gas Extended Analysis sample taken 5/11/2018 and the working/breathing errissions were calculated using Tanks 4.0.9d. The emission factors and emissions above are slightly different from those requested by the source due to rounding; however, beca use the difference is less than 10%, the difference is considered negligable and the permit will reflect the requested values by the source.

The emission factors requested by the source are listed in lb/Mscf, whereas the emission factors calculated above are in Ib/MMscf; however, in spite of some small rounding differences (as discussed in the description above), the resulting emission factors calculated aligned with those requested by the source. The permit will refect the emission factors as requested by the source. During permitting process, the source determined that the control devices were enclosed combustion devices and not thermal oxdizers, as originally requested.
