(I) Emission averaging programs.

(1) An owner or operator of a source which is subject to this chapter may propose an emission averaging program in lieu of the applicable emissions limitations specified in paragraphs (A) to (G) of this rule or established in accordance with paragraph (J) of this rule. Both affected sources under rule 3745-110-02 of the Administrative Code and non-affected sources are allowed to be utilized in the averaging program, to the extent that reductions are real, quantifiable and enforceable and are in excess of any state or federal requirements. Any proposed emission averaging program shall comply with all of the following requirements:

(a) Specify the RACT emissions limitation for each affected source in rule 3745-110-02 of the Administrative Code involved in the emission averaging program.

(b) Specify a clearly enforceable proposed emissions limitation for each source or group of sources involved in the emission averaging program.

(c) Result in actual reductions in NOx emissions that are equal to or greater than the actual emission reductions that would be required by this rule if an emission averaging program were not employed.

(d) Achieve compliance with the proposed emissions limitation in accordance with the compliance deadlines in rule 3745-110-04 of the Administrative Code.

(e) Reductions allowed under the emission averaging program are those reductions that are real, quantifiable and enforceable and are in excess of any state or federal requirements. For purposes of determining the reductions, the actual emissions in tons per year, from all sources included in the averaging program, are subtracted from the lesser of either the actual annual average emissions prior to when the actual reduction occurs or the allowable emissions. A shutdown is creditable only to the extent that the owner or operator can demonstrate to the satisfaction of the director that the shutdown does not correspond to load-shifting or other activity which results in or could result in an equivalent or greater emission increase and that the reduction accounts for any increase in NOx emissions from other sources as a result of the shutdown.

(f) Owners or operators must submit a report to the director by March thirty-first of each year demonstrating that the equivalent reduction requirement in paragraph (I)(1)(c) of rule 3745-110-03 of the Administrative Code has been achieved for the previous calendar year.

(2) Any emission averaging program approved by the director shall be submitted to and approved by the United States environmental protection agency as a revision of the Ohio state implementation plan. An emission averaging program shall not be federally enforceable until the United States environmental protection agency approves the program as part of the Ohio state implementation plan.

The detailed engineering study shall be conducted by an engineering consulting firm or other person or persons experienced in the field of air pollution control, and provide the following information:

(a) The complete facility name and address.

A detailed engineering discussion is not required for those control measures which are not applicable to a particular source.

(i) For each type of control measure that is determined to be technically feasible, an estimate of the control efficiency that can be achieved.

(j) For each control measure that is determined to be technically feasible, an estimate of the capital cost, annualized cost (including capital and operating costs), and the cost-effectiveness (annual dollars per ton of NOx removed annually).
