In addition, any such use or purchase of emission reduction credits shall be consistent with the United States Environmental Protection Agency's "Economic Incentive Program Rules; Final Rule," of April 7, 1994 (59 Fed. Reg. 16690), and the United States Environmental Protection Agency's "Emission Trading Policy Statement" of December 4, 1986 (51 Fed. Reg. 43814). The commissioner may only allow the use of either alternative emission reductions pursuant to section 22a-174-20(cc) of the Regulations of Connecticut State Agencies or emission reduction credits through the issuance of a permit or order. The commissioner shall submit such permit or order to the Administrator for approval in accordance with the provisions of 42 U.S.C. 7401-7671, et seq. Nothing herein shall require the commissioner to issue such permit or order.(6) The commissioner may issue a permit or order to the owner or operator of a premises requiring the implementation of an alternative compliance plan when it is demonstrated, to the commissioner's satisfaction, through the information submitted pursuant to subdivision (d)(2) and (d)(6) of this section, that compliance with subparagraphs (1)(A) through (1)(C) of this subsection, inclusive, is not technologically or economically feasible. Such permit or order shall specify that the implementation of the approved alternative compliance plan shall be Reasonably Available Control Technology for such premises. Such owner or operator shall implement the alternative compliance plan by the date specified in the permit or order, which date shall be no later than ninety days after issuance of such permit or order. In issuing such a permit or order the commissioner may consider the VOC emissions and the VOC emission reductions made at the premises after 1986. The commissioner shall submit such permit or order to the Administrator for approval in accordance with the provisions of 42 U.S.C. 7401-7671, et seq.(7) Notwithstanding the provisions of subdivision (6) of this subsection, nothing herein shall require the commissioner to issue such permit or order.(f)Test Methods.(1) Upon written notification that the commissioner shall require emissions testing to demonstrate compliance with this section or any permit or order issued hereunder, the owner or operator of a premises shall conduct such testing in accordance with such notification and section 22a-174-5 of the Regulations of Connecticut State Agencies.(2) Where an owner or operator uses a system to capture and control VOC emissions pursuant to subparagraph (A) of subdivision (e)(1) of this section, compliance with this section shall be demonstrated by using the sampling and analytical procedures set forth in 40 CFR Part 60, Appendix A or 40 CFR Part 52.741, Appendix B.(3) Where an owner or operator uses any Reasonably Available Control Technology methods pursuant to subparagraphs (B) through (D) inclusive of subdivision (e)(1) of this section, the commissioner may require compliance with this section be demonstrated by: (A) using sampling and analytical procedures set forth in 40 CFR Part 60, Appendix A;(B) using a mass balance procedure based on known quantities of materials purchased, stored in inventory, and/or reclaimed using good engineering practice, as approved by the commissioner; or(C) using other methods or procedures approved by the Administrator.(g)Record keeping.(1) After December 31, 1996, the owner or operator of a premises shall maintain for at least five years at such premises, and make available at such premises for the commissioner's inspection upon demand, the following:(A) purchase records for all materials which are used or stored at such premises which contain VOCs;(B) for any VOC emissions resulting from coating operations, records of the name of each coating, the coating density expressed in pounds per gallon or pounds per unit, the percent VOC content by weight of each coating, the percent solids content by weight, the water and exempt VOC content of each coating by weight, the amount of each coating used in gallons, the total amount of diluent used for each coating in pounds and in gallons, and the coating viscosity in pounds VOC per pounds solid or in kilograms VOC per kilogram solids; and(C) the results of any VOC emissions testing performed pursuant to subsection (f) of this section.(2) The owner or operator of a premises shall make, keep and maintain for at least five years at such premises any other records required to kept by an individual permit, general permit or order.Conn.
