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). GENERAL TERMS AND CONDITIONS 18. 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. 19. 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. 20. 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. 21. 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. 22. 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 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.

MN 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. Does the company request a control device efficiency greater than 95%for a flare or combustion device? • tf yes,the permit will contain and inital compliance test condition to demonstrate the destruction efficiency of the combustion device based on inlet and outlet concentration sampling ds� . 3x,9 .. _ Section 09-inventory SCC Cathie and Emissions Factor= Uncontrolled Emissions AIRS Point if Process* SCC Code Pollutant Factor Control%Units 011 01 PM10 0.00 0 lb/1,000 gallons condensate throughput PM2.5 0.00 0 lb/1,000 gallons condensatethrouthput NOx 0.00 0 lb/1,000 gallons condensate throughput VOC 170.0 95 lb/1,000 gallons condensate throughput CO 0.00 0 lb/1,000 gallons condensate throughput Benzene 3.45 95 lb/1,000 gallons condensate throughput Toluene 2.79 95 Ib/1,000 gallons condensate throughput Ethylbenzene 0.26 95 Ib/1,000 gallons condensate throughput Xylene 0.73 95 lb/1,000 gallons condensate throughput n-Hexane 18.24 95 Ib/1,000 gallons condensate throughput 224 TM' 1.06 95 lb/1,000 gallons condensate throughput 2 of 2 K:\PA\2015\15WE1215.CP1.xlsm • 4' p.
