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. Ho 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. 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. Yes 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 Operator ran both EPA Tanks and ProMax to separately calculate Working & Breathing losses and flash losses. Ran ProMax at a 1 bbl/day basis to directly calculate EFs for flashing and speciation of vapors. EF for VOC calculated by adding ProMax flash EF (5.636 lb/bbl VOC) to W&B losses calculated by EPA Tanks (0.137 lb/bbl/tank` 3 tanks= 0.412 lb/bbl). Flash EFs for HAPs from Promax W&B Els for HAPs calculated by multiplying total W&B emission factor by the mass fraction of each HAP taken from the Promax flash gas composition. NOTE: Operator used slightly different equations to calculate annual heat sent to combustors. Operator assumes that waste gas is not 100% VOC and factors this into calculations by dividing volume of waste gas emitted by the percentage of VOC in the stream. Operator calculation provides more conservative values, so will accept and use for this permit. Slightly different emissions calculated than APEN due to rounding. APEN values are acceptable, and will be used in notes to permit holder. • Section 09 - Inventory SCC Coding and Emissions Factors AIRS Point # 001 Process # SCC Code 01 4-04.0034 if H.

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 Operator used AP -42 Loading loss equation to calculate emission factor for VOC. Emission factors for HAPs were calculated by multiplying the VOC emission factor (found by AP -42 Loading loss equation) by the ratio of the emission factors of each HAP to VOC found from the ProMax condensate tank flash analysis used to calculate the SSEFs used for point 001. ex: ProMax run gives: n -Hexane EF = 0.07361 lb/bbl VOC EF = 5,63619 lb/bbl - > n-Hexane/VOC = (0.07361 lb/bbl) / (5.63619 Ib/bbl) = 0.01306 (lb n -Hexane / lb VOC) Loadout VOC EF = 0.238 lb/bbl > n -Hex Loadout EF = (0.01306 lb n-Hex/lb VOC) * (0.238 lb VOC/bbl) = 0.00311 lb n-Hex/bbl (n -Hex Loadout EF) Additionally, operator calculated NOx and CO emissions based on the following values: PTE = 837 MMBtu/yr Actual = 698 MMBtu/yr These values were calculated relatively conservatively - Operator chose to use a lesser molecular weight when calculating the volume of waste gas emitted per year (45 rather than the 65 used in the loadout equation) resulting in a more conservative EF. Additionally, operator chose to divide the "annual heat content to combustion device" by the weight percent of VOC in that vapor stream, again providing a more conservative EF for NOx and CO. Given that these methods are more conservative than calculated by PA, will accept and use these values. (PA values still included in book, but not used).

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 Testing Requirement" to collect a site -specific gas sample from the equipment being permitted and conduct an emission factor analysis to demonstrate that the emission factors are less than or equal to the emissions factors established with this application. Are facility -wide permitted emissions of VOC greater than or equal to 90 tons per year? If yes, the permit will contain: - An "Initial Testing Requirement" to collect a site -specific gas sample from the equipment being permitted and conduct an emission factor analysis to demonstrate that the emission factors are less than or equal to the emissions factors established with this application. - A "Periodic Testing Requirement" to collect a site -specific gas sample from the equipment being permitted and conduct an emission factor analysis to demonstrate that the emission factors are less than or equal to the emissions factors established with this application on an annual basis. Will the operator have a meter installed and operational upon startup of this point? Yes If no, the permit will contain a condition that requires the operator to calculate gas throughput using the liquid throughput until the meter is installed and operational (not to exceed 180 days). This condition will use the "Volume of waste gas emitted per BBL of liquids throughput" (scf/bbl) value in section 03. 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 You have indicated above that the monitored process parameter is natural gas vented.

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 gas venting only. Gas venting includes emissions from gas/liquid separators, well head casing, pneumatic pumps, blowdown events, among other events. If your emission unit does not fall into this category, there may be a more specific APEN for your source (e.g. amine sweetening unit, hydrocarbon liquid loading, condensate storage tanks, 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 can be found on the Air Pollution Control Division (APCD) website at: www.colorado.gov/cdphe/apcd. 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.).
