(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.
