Section 07-Initial and Periodic Sampling and Testing Requirements
For condensate or crude oil tanks,does the company use the state default emissions factors t - ,
estimate emissions? a If yes,are the uncontrolled actual or requested emissions fore crude oil tank estimated to be greater than or equal to 20 tons VOC per year OR are the
uncontrolled actual or requested emissions fora condensate storage tank estimated to be greater than or equal to 80 tpy?
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 1 quid sample drawn at the facility being `v`-t v
permitted(for produced water tanks,a pressurize liquid sample must be analyzed using flash liberation analysis).This sample - *s
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. ,
Brio,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 Wacker 10E-
302 well.This well is one of the eleven(11)wells dulled at this fac lily and there were no significant changes to the facility since the development 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 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(MMBtut/yr)=[Uncontrolled VOC(ton/yr)} [2000(Ib/ton)]=.MW(lb/lbmo1).e[379.41(scf/IbmoI)] [1/VOC mot%]s[Heat Content(Btu/scf)].[1MMBtu/(1000,000 tu)J.
The values used in the equation were obtained from a Pro Max simulation used to calculate emissions and develop emission facto-.The values used are as follow:(i)Molecular weight.46.4 lb/lb-mol,(iij VOC mo1%:
73.08%,(iii)Heat Content:261'0.23.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 o perator.The permit will not contain initial or periodic
opacity testing for the enclosed combustor(s)because the O&M plan approved for this source requires weeklyvisible emissionsobservations of the enclosed combustor(0.Athroughput 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 became 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. -
4.Self-certification was submitted on 2/18/2020.The Division approved the self-certification on 03/18/2020.
5.A permit draft was sent to operator for review.Operator had a comment about the requested condensate throughput which was corrected to match the APEN

Form APCD-205
CDPHE Air Pollutant Emission Notice(APEN) and
Application for Construction Permit
All sections of this APEN and application must be completed for both new and existing facilities, including APEN
updates. 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.
