Annual performance testing shall be conducted for each pollutant (PM or TSM, HCl, or Hg) for which compliance is demonstrated through emissions averaging. Each performance test must be completed no more than 13 months following the previous performance test for each existing boiler participating in emissions averaging within the subcategory. [40 CFR 63.7515(a) and (c)] This term (#7) would probably not be needed in a permit; but may be used as guidance for the review of the emissions averaging implementation plan. Upon receipt of the emission averaging implementation plan, the regulatory authority (appropriate district or local office of the Ohio EPA, Division of Air Pollution Control) shall review and approve or disapprove the plan according to the following criteria: the content of the plan shall include all of the information specified in paragraph 40 CFR 63.7522(g)(2), as required above; and the plan shall present sufficient information to determine that compliance will be achieved and maintained. The emission averaging implementation plan shall not be approve if it contains any of the following scenarios: it does not specify that emissions averaging is to be calculated for each pollutant individually (or for which pollutant(s) emission averaging is to be considered); or it proposes averaging between emissions of different pollutants; it does not include all of the information specified in paragraph 40 CFR 63.7522(g)(2), as required above; or the plan includes any emission source other than existing boilers; or boilers from different subcategories are included in the same averaging group. [40 CFR 63.7522(g)(3) and (4)] Where a group of 2 or more existing boilers in different subcategories vent through a common stack, the emission limit for the stack shall be calculated using Equation 6 from 40 CFR 63.7522(j)(1), where the summation of the emission limits from Table 2 for the individual units is dividing by the summation of the heat input from each unit sharing the stack: n n En = = (Eli x Hi) / Hi ∑ ∑ i = 1 i = 1 Where: En = HAP emission limit, in lbs/MMBtu, ppm, or nanograms/dscm (ng/dscm)
