(A) Beginning January 1, 1996, or for a unit subject to section 404(D) of the Clean Air Act, the date on which the unit is required to meet acid rain emission reduction requirements for SO2, the owner or operator of a phase I coal-fired utility unit with a tangentially fired boiler or a dry bottom wall-fired boiler (other than units applying cell burner technology) shall not discharge, or allow to be discharged, emissions of NOx to the atmosphere in excess of the following limits, except as provided in paragraph (C) or (E) of this rule or in rule 3745-103-62 or 3745-103-63 of the Administrative Code:

(1) Forty-five hundredths pound per MMBtu of heat input on an annual average basis for tangentially fired boilers.

(2) Fifty hundredths pound per MMBtu of heat input on an annual average basis for dry bottom wall-fired boilers (other than units applying cell burner technology).

(B) The owner or operator shall determine the annual average NOx emission rate, in pound per MMBtu, using the methods and procedures specified in 40 CFR Part 75.

(C) Unless the unit meets the early election requirement of rule 3745-103-60 of the Administrative Code the owner or operator of a coal-fired substitution unit with a tangentially fired boiler or a dry bottom wall-fired boiler(other than units applying cell burner technology) that satisfies the requirements of paragraph (C)(2) of rule 3745-103-55 of the Administrative Code, shall comply with the NOx emission limitations that apply to group one, phase II boilers.

(E) The owner or operator of a phase I unit with a group one boiler that converts to a fluidized bed or other type of utility boiler not included in group one boilers on or before January 1, 1995 or, a unit subject to Section 404(d) of the Clean Air Act, the date the unit is required to meet acid rain emissions reduction requirements for SO2 is exempt from the NOx emissions limitations specified in paragraph (A) of thisrule, but shall comply with the NOx emission limitations for group two boilers under rule 3745-103-58 of the Administrative Code.
