Management of toxic substances: dry cleaning sector

Tetrachloroethylene, also known as perchloroethylene, is commonly referred to as PERC or PCE. Although no longer produced in Canada, PERC continues to be imported, primarily for domestic use. Releases of PERC to the environment occur predominantly from the dry cleaning sector which is a major user of this solvent. Most of the PERC used in dry-cleaning is lost to the environment as air emissions during the dry-cleaning process, or into water from spills or improper disposal of wastes. PERC was added to the CEPA 1999 list of toxic substances on March 29, 2000. The final Tetrachloroethylene (Use in Dry Cleaning and Reporting Requirements) Regulations were passed into law on February 27, 2003.
