MENDOCINO COUNTY AIR QUALITY MANAGEMENT DISTRICT

RULE 7-110 - PURPOSE

On October 10, 1991, pursuant to Section 39662 of the Health and Safety Code, the Air Resources Board (ARB) identified perchloroethylene as a toxic air contaminant for which there is not sufficient available scientific evidence to support the identification of a threshold exposure level below which no significant adverse health effects are anticipated (see Title 17, California Administrative Code, Section 93000). This airborne toxic control measure will reduce perchloroethylene emissions from dry cleaning operations and resulting cancer risk and cancer incidence to the lowest achievable level through application of best available control technology at operations subject to this measure.
