Federal regulatory program requirements (i.e. PSD, NANSR) must apply to this source at any such time that this source becomes major solely by virtue of a relaxation in any permit condition. Any relaxation that increases the potential to emit above the applicable Federal program threshold will require a full review of the source as though construction had not yet commenced on the source. The source must not exceed the Federal program threshold until a permit is granted. (Regulation Number 3, Parts C and D). GENERAL TERMS AND CONDITIONS 21. This permit and any attachments must be retained and made available for inspection upon request. The permit may be reissued to a new owner by the APCD as provided in AQCC Regulation Number 3, Part B, Section II.B. upon a request for transfer of ownership and the submittal of a revised APEN and the required fee. 22. If this permit specifically states that final authorization has been granted, then the remainder of this condition is not applicable. Otherwise, the issuance of this construction permit does not provide"final" authority for this activity or operation of this source. Final authorization of the permit must be secured from the APCD in writing in accordance with the provisions of 25-7-114.5(12)(a) C.R.S. and AQCC Regulation Number 3, Part B, Section III.G. Final authorization cannot be granted until the operation or activity commences and has been verified by the APCD as conforming in all respects with the conditions of the permit. Once self-certification of all points has been reviewed and approved by the Division, it will provide written documentation of such final authorization. Details for obtaining final authorization to operate are located in the Requirements to Self-Certify for Final Authorization section of this permit. 23. This permit is issued in reliance upon the accuracy and completeness of information supplied by the owner or operator and is conditioned upon conduct of the activity, or construction, installation and operation of the source, in accordance with this information and with representations made by the owner or operator or owner or operator's agents. It is valid only for the equipment and operations or activity specifically identified on the permit. 24. Unless specifically stated otherwise, the general and specific conditions contained in this permit have been determined by the APCD to be necessary to assure compliance with the provisions of Section 25-7-114.5(7)(a), C.R.S. 25. Each and every condition of this permit is a material part hereof and is not severable. Any challenge to or appeal of a condition hereof must constitute a rejection of the entire permit and upon such occurrence, this permit must be deemed denied ab initio. This permit may be revoked at any time prior to self-certification and final authorization by the Air Pollution Control Division (APCD) on grounds set forth in the Colorado Air Quality Control Act and regulations of the Air Quality Control Commission (AQCC), including failure to meet any express term or condition of the permit. If the Division denies a permit, conditions imposed upon a permit are contested by the owner or operator, or the Division revokes a permit, the owner or operator of a source may request a hearing before the AQCC for review of the Division's action.

This sample should represent the gas outlet of the equipment covered under this AIRs ID,and should have been 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 maybe 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 40 tons per year in the ozone nonattainment area OR are emissions greater than or equal to 90 tons per year in the ozone attainment area? '14 „ tq 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 initial and periodic compliance testing in accordance with PS Memo 20-02 1,00:10 itdatliattlfigigs;WaililaragPlegibilfsONIZAOSPOWS4104.011enhilliglijiigniatelifilailiftige solowsz{> its °}' zm a ' ; , ", - n., v.,xo ", iwaisfaisio ,..:as 2 ,agigitlike'. .

The pressurized liquid sample was taken from the outlet of an HP separator at a similarly configured facility.With respect to the HYSYS simulation,"V-100"was used to look at the gas composition associated with the outlet HP sample and"VRT Hypo"was used to look at the gas composition at 4 prig.Since there are multiple streams at different pressures hitting the condensate knockout vessel,we modeled high(V-100)to lower(VRT Hypo)pressures to see a range of compositions. The"Misc Vap to Burner 2"composition correlated to the most conservative emission factors,so it was used in the applicatlm.It should also be noted that a gas sample was taken from this foci liy et the combustor header.This sample is representative of gas being burned from this knockout vessel and shows that the modeled compositions are more conservative lie.higher VOC content on a mass basis). tc Section 09-SCC Coding and Emissions Factors(For Inventory Use Only) AIRS Point# Process# SCC Code Pollutant Uncontrolled Emissions Factor Control% Units 006 01 3-105111-55Fi0555PM10 10.3 PM2.5 18.8 SOz 1.5 0 NOn 173.3 0 VOC 90207.6 9y CO 757,9 J ..

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 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 wilt 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. 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.).
