South Coast AQMD Exempt VOC List
South Coast AQMD Exempt VOC List
The South Coast AQMD classifies exempt compounds as Group I and Group II Exempt Compounds. Some rules include prohibitions from using certain Group II Exempt Compounds as they have potential toxic health risks, as well as being contributors to upper-atmosphere ozone depletion and other potential environmental impacts. The following general prohibition is included in Rule 1113 (PDF) - Architectural Coatings, Rule 1143 (PDF) - Consumer Paint Thinners and Multi-Purpose Solvents, and Rule 1168 (PDF) - Adhesive and Sealant Applications:
"No person shall supply, sell, market, offer for sale, manufacture, blend, or repackage any architectural coating, consumer paint thinner or multi-purpose solvent in the District subject to the provisions of this rule with any materials that contain in excess of 0.1% by weight any Group II exempt compounds listed in Rule 102. Cyclic, branched, or linear, completely methylated siloxanes (VMS) are not subject to this prohibition."
