Perchloroethylene (Perc) dry-cleaning facilities
The perc NESHAP was implemented in the early 1990s, and has been amended or updated by EPA to reduce perc emissions and protect worker health and the environment. As a result, EPA estimates its most recent rule reduced perc emissions by an estimated 5,700 tons per year. Today most dry cleaners are moving away from perc and using less-toxic alternatives. At a minimum, perc dry cleaners must comply with the following:
- File an initial notification for the perc NESHAP.
- Use modern dry-to-dry machines equipped with a refrigerated condenser or equivalent control device.
- Inspect the system weekly for perc leaks, using a perc gas analyzer for this inspection at least once each month.
- Maintain records of perc purchases and monthly perc purchase running totals.
- Repair or address any air leaks within 24 hours.
- Manage all separator-water issues.
- Maintain records for at least five years.
