While the following requirement is not called for by the Oregon Dry cleaner law it is required by federal air quality regulations and is included here to give a complete picture of what requirements dry cleaners must comply with.
Perc is released into the air from dry cleaning machine vents and from “fugitive” emissions. Fugitive emissions occur when the machine doors are opened to remove clothing, when you clean filters, and any time the machine is left open. They can also occur because of equipment leaks.
All perc dry cleaners must keep records of their monitoring activities for leak detection and repairs, refrigerated condenser temperature, and monthly perc purchases. DEQ provides Oregon dry cleaners with a calendar to assist with specific monitoring and recordkeeping requirements, such as:
Date and amount of perc purchases;
Weekly refrigerated condenser outlet temperature log (temp must be less than or equal to 45 F at the end of the cool down cycle); and
Weekly or bi-weekly leak detection inspection log (depending on how much perc is used per year), including a log for tracking leak repair activities.
