(3) A thirty-day heat input-weighted average emission rate based on the twenty-four-hour daily heat input-weighted averages if a temporary continuous emissions monitor is used to demonstrate compliance in accordance with paragraph (C) of rule 3745-110-05 of the Administrative Code. Determine the twenty-four-hour daily heat input-weighted average NOx emission rate based on the heat input-weighted average of the block hourly arithmetic average emission rates during each twenty-four-hour daily period from twelve a.m. to twelve a.m. the following day using continuous emissions monitor data.

(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.(J) RACT studies for stationary sources.

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, Ohio EPA air program facility identification number, and address.(b) The name, title, address and telephone number of the owner or operator's representative within the company who is the contact person for this facility regarding the engineering study and affected sources.(c) The name, title, address and telephone number of the official who is responsible for approval of the engineering study.(d) The standard industrial classification code and source classification code numbers which are applicable to the facility's operation.(e) The following general information for each affected source: (i) Ohio environmental protection agency application number.(ii) Company identification and Ohio EPA emissions unit identification number.(iii) Source description.(iv) Month and year installed.(v) Normal operating schedule (hours per day, days per week, and weeks per year).(vi) Annual production rates for each of the three full calendar years preceding the effective date of this rule.(vii) Average and maximum daily production rates for each of the three full calendar years preceding the effective date of this rule.(viii) The type of control equipment employed and the date installed.(f) A plot plan which shows the general layout of the facility and the affected source.(g) The following emissions data for each affected source:(i) Average daily NOx emissions (pounds per day of operation) based upon the highest average daily production rate for each of the three full calendar years preceding the effective date of this rule or any other year that may be representative of the highest average daily emissions.

Average daily production rate = [(total production rate during the calendar year) / (number of days production occurred during the calendar year)]
Repeat the calculation for each of the three calendar years preceding the effective date of this rule. The highest value of these three years is the representative value used to calculate the average daily NOx emissions per year.]

(2) For any source that is subject to an emissions limitation contained in paragraphs (A) to (G) of this rule, if the director approves a definition of RACT and a schedule of compliance for the source pursuant to paragraph (J) of this rule, the source shall no longer be subject to the emissions limitations contained in paragraphs (A) to (G) of this rule. For any source that is subject to an emissions limitation contained in paragraph (A) to (G) of this rule, if the director disapproves a definition of RACT and a schedule of compliance for the source pursuant to paragraph (J) of this rule, or if the RACT study determines the applicable NOx emissions limitations contained in paragraphs (A) to (G) of this rule is technically feasible and economically reasonable (i.e., cost-effective) to achieve, or if the director disapproves of a variance application pursuant to paragraph (L) of this rule, the source remains subject to the emissions limitations contained in paragraphs (A) to (G) of this rule and the applicable compliance deadline specified in paragraph (B) of rule 3745-110-04 of the Administrative Code.
