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. 23. 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. 24. 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.

Point Name Type Control Action 004 Separator Separator Venting Flare Newly reported source Five gas/liquid separator controlled by one open flare during pipeline downtime. Flare 004 has a minimum control efficiency of 95%. Equipment Description This source vents natural gas from a well head separator Emissions from this source are: routed to a flare Natural gas venting from a well head separator. Primarily, emissions from this source are routed to pipeline through closed loop system. When the pipeline is down, emissions are routed to a flare (open flare). Although the flare is designed for 98% efficiency and the closed loop has no emissions, Carrizo is accepting the conservative assumption of a constant 95% control efficiency for this source. There is one separator per well, and five wells included in this application.

The more conservative of the value calculated above and the value from the applicant will be used in the permit. 3) Applicant requested not to use CO & NOx combustion emission factors in the same terms as the permit process limit (lb/MMscf). Applicant feels the lb/MMscf emission factors do not appropriately represent the contribution of the pilot light gas, and requested that the emission factors in the permit be listed in the same units as they are listed in AP -42.

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. 24. 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. 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.

In addition, since the pipeline is pretty consistent for this site we have reduced the requested amount of gas being flared. We changed the control efficiency back to 95% for the combustor. Although it is fully capable of 98% Carrizo does not want to spend the time and money associated with periodic stack tests and monitoring the agency will require. All three sources; the oil tanks, water tanks, and oil loadout are all controlled by a single enclosed flare (combustor). There were two but one has been moved to another site. Also note, since the original submittal a GP -02 application was submitted for a VRU. Carrizo is still working through the operations of the unit and does not know if it will remain onsite. As such, no reduction in tank/loadout emissions have been requested for the VRU at this time. Please red -line the APENs and forms as appropriate. If you prefer us to submit updated APENs, just let me know.

The highest 12 month total wasn't until 2015 so I updated the 2014 actual numbers below. The requested is based on the highest 12 months * 1.1 for the tanks (oil and water). One other change is the combustor. There is only one now, not two, and with lower tank throughput emissions have decreased.
