The amendments also address manufacturers and distributors of perc. Manufacturers that sell perc for dry cleaning use in California must keep monthly sales records. In addition, they are required to report to ARB their distributors' contact information and any subsequent changes to that information. Perc is listed by the ARB as a toxic air contaminant (TAC); which is California's designation for chemicals that have no exposure level which can be considered safe.
Any solvent distributor that sells perc or recycled perc to California dry cleaning facilities or to another perc distributor is required to report annually to the ARB the amount of perc sold in California. And, if applicable, they must report the contact information of their distributors and subsequent changes to that information.
The California Air Resources Board is a part of the California Environmental Protection Agency, an organization which reports directly to the Governor's Office in the Executive Branch of California State Government.
