As an alternative to complying with the provisions of
Sections
4 through
6 above the operator of a solvent
cleaning machine may demonstrate compliance with Subsection A or B below. The
operator shall maintain records sufficient to demonstrate compliance. The
records shall include, at a minimum, the quantity of solvent added to and
removed from the solvent cleaning machine, the dates of the addition and
removal and shall be maintained for not less than 2 years.
A. If the cleaning machine has a solvent/air
interface, the owner or operator shall:
(1)
Maintain a log of solvent additions and deletions for each solvent cleaning
machine; and
(2) Ensure that
emissions from each solvent cleaning machine are equal to or less than the
applicable emission limit presented in Table 2.

B. If the
cleaning machine is a batch vapor cleaning machine and does not have a
solvent/air interface, the owner or operator shall:
(1) Maintain a log of solvent additions and
deletions for each solvent cleaning machine; and
(2) Ensure that the emissions from each
solvent cleaning machine are equal to or less than the appropriate limits as
described in Subsections C and D of this Section. Each owner or operator of a
batch vapor or in-line cleaning machine complying with Section 7 shall
demonstrate compliance with the applicable 3-month rolling average monthly
emission limit on a monthly basis.
C. For cleaning machines with a cleaning
capacity that is less than or equal to 2.95 cubic meters, the emission limit
shall be determined using the Table 1 or the equation in Subsection D. If the
table is used, and the cleaning capacity of the cleaning machine falls between
two cleaning capacity sizes, then the lower of the two emission limits
applies.
D. For cleaning machines
with a cleaning capacity that is greater than 2.95 cubic meters, the emission
limit shall be determined using the following equation.
EL = 330 (vol)0.6
where:
EL = the 3-month rolling average monthly emission limit
(kilograms/month).
vol = the cleaning capacity of machine (cubic meters).
E. Each owner or operator of a
batch vapor or in-line solvent cleaning machine complying with Section 7 shall
demonstrate compliance with the applicable 3-month rolling average monthly
emission limit on a monthly basis. If the applicable 3-month rolling average
emission limit is not met, an exceedance has occurred. All exceedances shall be
reported to the Department within 30 days of the determination of the
exceedance.
