ATCM for Automotive Maintenance and Repair Activities

This page last reviewed April 22, 2010

The ARB has approved an airborne toxic control measure (ATCM) that reduces chlorinated compound emissions from automotive consumer products used in automotive maintenance and repair (AMR) activities. Specifically, the ATCM prohibits the use of perchloroethylene (Perc), methylene chloride (MeCl), and trichloroethylene (TCE) in brake cleaners, carburetor or fuel-injection air intake cleaners, engine degreasers, and general purpose degreasers sold, supplied, offered for sale, or manufactured for use in California.

Perc, MeCl, and TCE have all been identified as toxic air contaminants and probable human carcinogens. Because AMR facilities are often found near residential neighborhoods and schools, the ARB is concerned about the public being exposed to toxic air contaminants from AMR activities. The ATCM will reduce public and worker exposure to Perc, MeCl, and TCE. The ATCM will also reduce the amount of these compounds reaching wastewater treatment plants and hazardous waste disposal sites.


Formal Rulemaking Activity

The ATCM was approved by the Office of Administrative Law on April 4, 2001, and is currently in effect. Please view the final regulation order, final statement of reasons, or initial statement of reasons.
