Federal regulatory program requirements (i.e. PSD, NANSR or Title V Operating Permit) shall 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 shall not exceed the Federal program threshold until a permit is granted. (Regulation No. 3 Part D). 19. MACT Subpart HH - National Emission Standards for Hazardous Air Pollutants From Oil and Natural Gas Production Facilities major stationary source requirements shall apply to this stationary source at any such time that this stationary source becomes major solely by virtue of a relaxation in any permit limitation and shall be subject to all appropriate applicable requirements of Subpart HH. (Reference: Regulation No. 8, Part E) GENERAL TERMS AND CONDITIONS 20. 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 No. 3, Part B, Section II.B upon a request for transfer of ownership and the submittal of a revised APEN and the required fee. 21. 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 No. 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. 22. 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. 23. 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. AIRS ID: 123/9A73 Page 5 of 8 Health and Environment r Pollution Control Division 24. Each and eve part hand is not severable. Any challenge to or appeal of a condition hereof shall constitute a rejection of the entire permit and upon such occurrence, this permit shall 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. 25. Section 25-7-114.7(2)(a), C.R.S. requires that all sources required to file an Air Pollution Emission Notice (APEN) must pay an annual fee to cover the costs of inspections and administration. If a source or activity is to be discontinued, the owner must notify the Division in writing requesting a cancellation of the permit. Upon notification, annual fee billing will terminate. 26. Violation of the terms of a permit or of the provisions of the Colorado Air Pollution Prevention and Control Act or the regulations of the AQCC may result in administrative, civil or criminal enforcement actions under Sections 25-7-115 (enforcement), -121 (injunctions), -122 (civil penalties), -122.1 (criminal penalties), C.R.S.

Regulation 8 — Hazardous Air Pollutants 006 MACT EEEE: Organic Liquids Distribution This source is not subject to MACT EEEE because it is not located at a major source of HAP. 006 MACT HH 1.Is facility a production field facility per 63.761 (Refer to Section 14 for definition)? Yes 2. If facility is defined as a production facility, then is it a major source of HAPS when summing up dehydrator and flash tank emissions? No 3.ls this facility considered MAJOR for HAPS? No 4.Is this source subject to MACT HH?

Operator provided site -specific emission factors with the application. The operator used WinSim for flashing losses and E&P Tank for W+B losses. The operator provided 2 gas analyses which both were sampled on 1/14/13, less than a year of the submittal application date. The operator took an average between the two samples (different wells at the same site) and averaged them to get the input for WinSim. VOC calculation: WinSim VOC emissions = 124.23 TPY with a projected production of 600,000 bbl/yr WinSim VOC emission factor =(124.23*2000)/600000 = 0.4141 lb/bbl E&P VOC emissions (for 1 tank) = 7.69 TPY " 18 = 138.35 TPY with a projected production of 600,000 bbl/yr E&P VOC emission factor = (138.35*2000)/600000 = 0.4612 lb/bbl Add the two together for the total VOC E.F. = 0.4141 + 0.4612 = 0.8753 lb/bbl (APEN shows 0.88 lb/bbl) Convert that to lb/1000 gal = 20.8405 lb/1000 gal The same method was used to calculate the emission factors for benzene and n -hexane: Component WinSim Emissions (TPY) WinSim E.F.

The definition of major source for MACT HH (63.761) states: (3) For facilities that are production field facilities, only HAP emissions from glycol dehydration units and storage vessels with the potential for flash emissions shall be aggregated for a major source determination. For facilities that are not production field facilities, HAP emissions from all HAP emission units shall be aggregated for a major source determination. The following definitions from 63.761 are also needed to determine major source applicability: Production field facilities means those facilities located prior to the point of custody transfer Custody transfer means the transfer of hydrocarbon liquids or natural gas: after processing and/or treatment in the producing operations, or from storage vessels or automatic transfer facilities or other such equipment, including product loading racks, to pipelines or any other forms of transportation. For the purposes of this subpart, the point at which such liquids or natural gas enters a natural gas processing plant is a point of custody transfer. Natural gas processing plant (gas plant) means any processing site engaged in the extraction of natural gas liquids from field gas, or the fractionation of mixed NGL to natural gas products, or a combination of both. Based on the definitions above, this source qualifies as a production field facility. May 20, 2013: During operator DRAFT review, the operator requested that the PTE throughput (864089 bbls) and corresponding emissions be used in the permit instead of the actuals listed on the APEN. I made these changes to the permit and PA. June 17, 2013: The operator sent an email requesting if they could increase the throughput because they are adding 8 additional wells. I figured that since the permit was still in draft, and was at supervisor review, I would make these changes to avoid out of compliance before the permit is issued. I made the changes to the PA, permit and history file on 6/28/13.
