Some businesses were required to switch from petroleum-based solvents to air compliance solvents (also called water-based cleaners). “Air compliance solvent" means solvents, including aqueous solutions, required or approved for use by the State Air Resources Board, an air pollution control district, or an air quality management district to meet air emission standards. For more information, contact your hazardous waste transporter or your local environmental agency.

Businesses that do not recycle their air compliance solvent waste who want to use the reduced $3.50 fee must use their internal records to identify manifests used solely for waste derived from air compliance solvents. DTSC does not have this information for you. You can find a list of Certified Clean Air Solvents on the South Coast Air Quality Management District’s website at www.aqmd.gov/rules/cas/prolist.html.
