EPA has proposed amendments to the National Perchloroethylene Air Emission Standards for Dry Cleaning Facilities. This proposal would add provisions which would require all dry-to-dry machines at new and existing facilities to have both refrigerated condensers and carbon adsorbers as secondary controls.
The request for comment period is currently open. EPA seeks comments and information regarding the number of third generation and earlier model dry cleaning machines that potentially could still be in operation. In addition, EPA seeks information on dry cleaning practices, processes, and control technologies that could reduce emissions from hazardous air pollutions, or HAPs, for fourth generation (or better) dry cleaning machines.
A copy of the rule summary, the new proposed rule, and fact sheets can be found here.
General speaking, most dry cleaning facilities and operations are small businesses. Estimates from EPA report that there are approximately 10,000 to 15,000 perchloroethylene dry cleaning facilities in the United States. Unfortunately, due to the COVID-19 pandemic it is estimated that 10-15% of perc dry cleaners have closed.
