§ 129.107. Special provisions for facilities using an emissions averaging approach.
(a) Emissions averaging approach. An owner or operator of a facility subject to the emission limitations in § 129.102 (relating to emission standards) may use an emissions averaging approach which meets the equivalency requirements in § 129.51(a) (relating to general) to achieve compliance with § 129.52 (relating to surface coating processes) or this section and § § 129.101—129.106.
(b) Additional requirement. When complying with the requirements of § 129.52 or this section and § § 129.101—129.106 through emissions averaging, an additional 10% reduction in emissions shall be achieved when compared to a facility using a compliant coatings approach to meet the requirements of this section and § § 129.101—129.106.
(c) Program goals and rationale. When using an emissions averaging program, the following shall be submitted to the Department in writing:
(1) A summary of the reasons why the facility would like to comply with the emission limitations through an equivalency determination using emissions averaging procedures.
(2) A summary of how averaging can be used to meet the emission limitations.
(d) Program scope. A description of the types of coatings that will be included in the facility’s emissions averaging program shall also be submitted to the Department in writing:
(1) Stains, basecoats, washcoats, sealers and topcoats may all be used in the emissions averaging program.
(2) The owner or operator of the facility may choose other coatings for its emissions averaging program, if the program meets the equivalency requirements in § 129.51(a).
(3) Coatings that are applied using continuous coaters may only be used in an emissions averaging program if the owner or operator of the facility can determine the amount of coating used each day.
(4) A daily averaging period shall be used, except under the following conditions:
(i) A longer averaging period may be used if the owner or operator of the facility demonstrates in writing to the satisfaction of the Department that the emissions do not fluctuate significantly on a day-to-day basis.
(ii) The owner or operator of the facility requests in writing and the Department approves in writing the longer averaging period.
(e) Program baseline. The baseline for each coating included in the emissions averaging program shall be the lower of the actual or allowable emission rate as of June 10, 2000. The facility baseline emission rate may not be higher than what was presumed in the 1990 emissions inventory for the facility unless the Department has accounted for the increase in emissions as growth.
(f) Quantification procedures. The emissions averaging program shall specify methods and procedures for quantifying emissions. Quantification procedures for VOC content are included in Chapter 139 (relating to sampling and testing). The quantification procedures shall also include methods to determine the usage of each coating and shall be accurate enough to ensure that the facility’s actual emissions are less than the allowable emissions.
(g) Monitoring, recordkeeping and reporting. A written summary of the monitoring, recordkeeping and reporting procedures that will be used to demonstrate compliance on a daily basis, when using an emissions averaging approach, shall be submitted to the Department.
(1) The monitoring, recordkeeping and reporting procedures shall be structured so that inspectors and facility owners or operators can determine a facility’s compliance status for any day.
(2) The monitoring, recordkeeping and reporting procedures shall include methods for determining required data when monitoring, recordkeeping and reporting violations result in missing, inadequate or erroneous monitoring and recordkeeping.
