No idling standard is proposed for batch cold cleaning machines. As an alternative to complying with the equipment standards option, each owner or operator of batch vapor or in-line cleaning machines may elect to comply by demonstrating that each solvent cleaning machine emits less than the overall solvent emissions limit specified in the standards. No alternative emission standards are proposed for batch cold cleaning machines. Existing solvent cleaning machines must achieve compliance with the rule no later than 36 months after promulgation. New solvent cleaning machines must achieve compliance with the rule immediately upon startup or by the promulgation date of the rule, whichever is later.
Continuous compliance is determined through periodic monitoring of process parameters.
Monitoring of individual controls is required for batch vapor and in-line cleaning machines that are complying with the equipment standard. In the case where the owner or operator of a batch vapor or in-line cleaning machine elects to comply with the alternative standards, compliance is determined by solvent consumption records and materials balance calculations of overall solvent emissions. Monitoring is not required for owners or operators of batch cold cleaning machines. Performance tests are required only if the idling emission limit standards are being used to comply with the rule and no vendor-supplied test is available for the specific model cleaning machine. The initial performance test demonstrates compliance with the idling standard and establishes monitoring parameters to demonstrate continued compliance.
