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. Table 2
EMISSION LIMITS FOR BATCH VAPOR AND IN-LINE
SOLVENT CLEANING MACHINES WITH A
SOLVENT/AIR INTERFACE
Solvent cleaning machine | 3-month rolling average monthly emission limit |
kg/m2/month | lb/ft2/month |
Batch vapor solvent cleaning machines | 150 | 30.7 |
Existing in-line solvent cleaning machines | 153 | 31.3 |
New in-line solvent cleaning machines | 99 | 20.2 |
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.06- 096 C.M.R. ch. 130, § 7
