Document Description
SCAQMD staff is proposing amendments to Rule 1143 - Consumer Paint Thinners and Multi-Purpose Solvents to: 1) re-establish the final VOC content limit for consumer paint thinners and multi-purpose solvents at 25 grams per liter (g/L), which is achievable using currently available low- and zero-VOC technologies from manufacturers; 2) add consumer warning requirements for all flammable and extremely flammable products; 3) add requirements to conduct a public education and outreach program in conjunction with local fire departments regarding flammable and extremely flammable projects; and 4) clarify the intent of the exemption for thinners for industrial maintenance (IM) coatings, zinc-rich IM primers, and high-temperature Im coatings. Other minor changes are proposed for clarity and consistency throughout the rule. The Draft Supplemental ES analyzes the potential fire hazards associated with Rule 1143 as revised.
