Residential Perc Dry Cleaning Facilities Phase Out by 2020

In July, 2006 US EPA issued standards (40 CFR 63.322) that included the phase-out of perchloroethylene (also know as "perc", "PCE", or
"Tetracholoethylene") dry-cleaning solvent machines located in residential buildings by December 21, 2020.

This standard means that dry cleaners using perc machines located in residential buildings (co-residential) will be prohibited from using perc. Those dry cleaners located in residential buildings who are still using perc should begin planning to switch to alternative cleaning methods such as wet cleaning, carbon dioxide or hydrocarbon technology.  Co-residential perc cleaners can also choose to relocate the perc dry cleaning solvent machines to another facility that is not attached to any residential apartment or living spaces.

In the rulemaking, EPA notes that perc is an organic solvent of known human toxicity and reasoned that perc dry cleaners located in residential buildings posed the greatest risk to the general public.
