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. 23. 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. 24. 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. 25. 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. 26. 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 AIRS ID: 123/9D5A Page 6 of 10 COP P° 4tpq met or`Public Health and Environment ,te-I Air Pollution Control Division 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. 27. 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. 28. 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.

AIRS Point Section 12—Regulatory Review Regulation 1 - Particulate, Smoke, Carbon Monoxide and Sulfur Dioxide Section II.A.1 - Except as provided in paragraphs 2 through 6 below, no owner or operator of a source shall allow or cause the emission into the atmosphere of any air pollutant which 005 is in excess of 20% opacity. This standard is based on 24 consecutive opacity readings taken at 15-second intervals for six minutes. The approved reference test method for visible emissions measurement is EPA Method 9 (40 CFR, Part 60, Appendix A(July, 1992)) in all subsections of Section II. A and B of this regulation. Regulation 2—Odor Section I.A- No person, wherever located, shall cause or allow the emission of odorous air contaminants from any single source such as to result in detectable odors which are 005 measured in excess of the following limits: For areas used predominantly for residential or commercial purposes it is a violation if odors are detected after the odorous air has been diluted with seven (7)or more volumes of odor free air. Page 3 Regulation 3-APENs, Construction Permits, Operating Permits,PSD Part A-APEN Requirements Criteria Pollutants: For criteria pollutants, Air Pollutant Emission Notices are required for: 005 each individual emission point in a non-attainment area with uncontrolled actual emissions of one ton per year or more of any individual criteria pollutant(pollutants are not summed) for which the area is non-attainment. (Applicant is required to file an APEN since emissions exceed 1 ton per year VOC) Part B—Construction Permit Exemptions 005 Applicant is required to obtain a permit since uncontrolled VOC emissions from this facility are greater than the 2.0 TPY threshold(Reg.3, Part B, Section ILD.2.a) emulation 6- New Source Performance Standards NSPS Kb: for storage vessels greater than 19,800 gallons after 7/23/84. Is this source greater than 19,800 gallons(471 bbl)? No 005 Is this source subject to NSPS Kb? No WHY? Sources do not meet the criteria of the subpart(tanks are less than 19,800 gallons each). Therefore it is not subject. NSPS OOOO: Tanks with the potential to emission equal to or greater than 6 TPY. Are uncontrolled VOC emissions greater than 6 TPY?Yes 005 Are controlled emissions greater than 6 TPY?Yes Is the operator requesting a permitted limit less than 6 TPY?

The tanks originally were submitted as GP01. Replies are in italics: 1. I am working on Rubyanna and I believe the facility is major. I say this because of the GP01. The controlled limit the GP01 gets is 39 TPY because that's the highest limit you can reach. By doing this, VOC emissions are greater than 100 TPY. I believe Kodak is still under the 100 TPY VOC threshold with the GP01. I don't believe this source would then qualify for the GP01. We can convert the GP01 to a permit to have a controlled emission of 10.6 TPY making this facility synthetic minor. The controlled actual emissions from my calculations are 10.55tpy with a 99.75%control. I know the GP-01 threshold will be set at 39tpy, but could Extraction set the PTE to be 12.7(that's the controlled actual with a bit of cushion)rather than permit to the full 39tpy? That way they could avoid a major source and remain a synthetic minor source. Please advise. No, this is how it is done for all GP01 across the state. 39 TPY is considered the controlled requested emission limit. Could they apply for individual permit with the 12.7 pte? Yes, they can do that. On June 8 I received a revised APEN via email requesting a CP for the tanks so that the facility can remain synthetic minor. 2. I have a question on the Rubyanna tanks. Will the flare be admitting NOx and CO? I feel because so much is coming out of these tanks(VOC)that there will be some combustion emissions either from the VRU or the combustor. Thoughts? Flare emission factors are usually taken from AP-42, with NOx= 0.068 lb/mmbtu and CO= 0.37 lb/mmbtu. Do you have calculations for these sources? I received ECD calculations via email on 7/11/2015. NOx = 0.068 lb 12 mmbtu 8760 = 3.57 TPY mmbtu hr 2000 CO= 0.31 lb 12 mmbtu 8760 = 16.29 TPY mmbtu hr 2000 Page 5 a �, 33 ., s O OO 1, A+ w z �-. ,� p $ O m vl N �J E �0 ❑❑ aet en en en M ❑ 0 N 2 Q:ti > o Z 0 r N N N VI m A d E; p�� O W w C O 0 O .Z s' e, yW .0 E'.( 4.0 .yam s A.
