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 far a condensate storage tank estimated to be greater than or equal to 80 toy? 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 missions,are the emissions factors based on a pressurized liquid sample drawn at the fist hty being r permitted(for produced water tanks, 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 u �, date.However,0the facility has not been modified(e.g.,no new wells brought on line),then it maybe appropriate to use an older site-specific sample. Yest, 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 the]Clark 13N well.This well is one of the twenty-one(21)wells drilled at this facility and there were no significant changes to the Maly since the development of the emissions factors.Asa result,the permit will not require initial testing in order to obtain a new site speciPcsample It should be noted that the sample includes sample probe temperature aid 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(MMBtu/yr)=[Uncontrolled VOC(ton/yr)].[2000(lb/ton)]4.-MW(lb/ibmoI)*[379.41(scf/IbmoI)].[1/VOC mot Vol [Heat Content(Btu/scf)]_[1MMBtu/(1000,000 Btu)]. The values used in the equation were obtained from a Pro Max simulation used to calculate emissions and develop emission factors.The values used areas follow:(i)Molecular weight:46.2lb/Ib-mol,(iii VOC mot%: 70.7°.6,(iii)Heat Content:2593.2 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 operator.The permit will not contain m Rol or periodic opacity testing for the enclosed comhustor(s)because the O&M plan approved for this source requiresweeklyvisible 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 becase 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.

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..).

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 hydrocarbon liquid loading only. 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, glycol dehydration unit, 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. This emission notice is valid for five(5)years.
