If yes, are the uncontrolled actual or requested emissions estimated to be greater than or equal to 80 tons VOC per year? 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. NA. Does the company use a site specific emissions factor to estimate emissions? Yes 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 modified (e.g., no new wells brought on-line), then it may be appropriate to use an older site -specific sample. i t. r 5: 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? 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 A pressurized liquid sample was taken on 1/22/2019 at the Barr II sec Pad Site, Unit ID Barr 3N. The sample was taken by Air Pollution Testing, Inc at a Probe Temp of 99 deg F and a Probe Pressure of 26.1 psig. An Extended Natural Gas Liquid Analysis was provided by the applicant that listed the components and the respective Mole % of this sample. This data was input into ProMax 4.0 to estimate both Flash and W&B losses. The secondary combustion emissions were calculated using the estimated Vapor Volumetric Flow and the Gross Heating Value, both from ProMax. The applicant estimated heat content using the following equation. This was accepted since it resulted in a more conservative value then the ProMax model.

An application with missing information may be determined incomplete and may be returned or result in longer application processing times. You may be charged an additional APEN fee if the APEN is filled out incorrectly or is missing information and requires re -submittal. 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 at: www.colorado.Rov/pacific/cdphe/air-permits. 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.).

Please see below for PDC's comments on the draft permits. Because claiming tank VRU in condensate tank permits is fairly new to PDC, we're still working through establishing 'common' permit language. I recently worked through the condensate tank permit language for PDC's Sandin Facility (Draft Permit 18WE1191) with Harrison Slaughter and most of the comments below regarding tank VRU conditions mirror the language we came up with in that permit. PDC's preference would be to have similar compliance requirements for similar sources if the Division finds that agreeable. Draft Permit 19WE0104 - Barr Condensate Tanks Equipment Description Table (page 1): Emissions Control Description - Can the control description be changed to read "Emissions from the storage vessels are routed to a sales pipeline through the use of a vapor recovery unit (VRU). During VRU downtime, emissions are routed to enclosed combustor(s). The VRU has a maximum of 63.9% annual downtime."? Condition 1: Requirement to Submit a Notice of Startup (NOS) - A hard copy NOS form was submitted with the original application package. An electronic NOS has also been submitted to associate the AIRS ID and permit number assigned to the condensate tanks since the original submittal. Please see the attached e -NOS receipt. Can this requirement be removed from the permit? Condition 8: Emissions Control Table - Can the two rows of this table be combined into a single row with the Control Device described as "Emissions from the storage vessels are routed to a sales pipeline through the use of a vapor recovery unit (VRU). During VRU downtime, emissions are routed to enclosed combustor(s). The VRU has a maximum of 63.9% annual downtime."? Condition 9: Process Limits Table - Can the process parameters be changed to "Total Condensate Throughput" (with an Annual Limit of 1,000,700 barrels) and "Condensate Throughput During VRU Downtime" (with an Annual Limit of 639,447 barrels)? Conditions 10 & 11: Relating to VRU Downtime Monitoring/Recording and Emissions Calculations for Demonstrating Compliance - Can these two requirements be combined into a single requirement that reads "The owner or operator shall monitor and record VRU downtime on a daily basis. VRU downtime shall be defined as times when emissions from the condensate storage vessels are routed to the enclosed combustor(s) rather than the VRU. The total hours of VRU downtime, total condensate throughput volume, and total condensate throughput volume during VRU downtime shall be recorded on a monthly basis. The owner or operator must use monthly VRU downtime records, monthly condensate throughput volume records, and the calculation methods established in the Notes to Permit Holder to demonstrate compliance with the process and emission limits specified in this permit."? Notes to Permit Holder #5: Emission Factors and Calculation Methodology.- Can the note below the table be changed to read "The controlled emissions factors for this point are based on a control efficiency of 100% when emissions are routed to the VRU and a control efficiency of 95% when emissions are routed to the enclosed combustor(s) during VRU downtime. Uncontrolled actual VOC and HAP emissions are calculated by multiplying the emission factors in the table above by the total condensate throughput. Controlled actual VOC and HAP emissions are calculated by multiplying uncontrolled emissions by a 100% control efficiency when emissions are routed to the VRU and a 95% control efficiency when emissions are routed to the enclosed combustor(s) during VRU downtime. 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 /b/bbl using a GOR of 45.33 scf/bbl and a heat content of 2580 Btu/scf. Actual NOx and CO emissions are calculated by multiplying the emission factors in the table above by the total condensate throughput during VRU downtime."? Draft Permit 19WE0186 - Clark/J Clark Condensate Tanks Condition 1: Requirement to Submit a Notice of Startup (NOS) - Because this is an existing source that required re - permitting due to a modification, can this requirement be removed from the permit? Condition 17: Method 22 Initial Testing Requirements - Similar to the comment above, because this is an existing source, and one that has been subject to the monitoring requirements of CO Regulation No. 7 (specifically the 6/24/2019 State.co.us Executive Branch Mail - RE: [EXTERNAL] :Barr and Clark Permit Review requirements regarding tank combustion devices operating without visible emissions), can this requirement be removed from the permit? Please let me know what your thoughts on the above comments are or if you would like to discuss any further. Also, I have attached an updated O&M plan for the Barr condensate tanks that is more aligned with the changes mentioned above. Please also let me know if you find this acceptable. Finally, as I was going through all of this I realized there are two condensate tank APEN redlines that may make sense. Would you agree that redlining Section 6 to: a) show a VRU Control Efficiency of 100% and VRU Downtime of 63.9% (these values maintain the total CE of 96.81%) and b) show the Combustion Device Waste Gas Heat Content of 2,580 Btu/scf would better reflect the permit as drafted? Please let me know your thoughts.
