Proposed Amended Rule 1107 – Coating of Metal Parts and Products

The South Coast Air Quality Management District is implementing Proposed Amended Rule 1107 to reduce emissions of volatile organic compounds from metal coating operations by phasing out the use of two toxic chemicals, para-Chlorobenzotrifluoride and tert-Butyl Acetate, due to their health risks. This rule amends existing regulations to prohibit the manufacture, sale, and use of coatings containing more than trace levels of these substances, with implementation timelines that include sell-through and use-through provisions to allow manufacturers, distributors, and end users adequate time to transition to compliant alternatives. The rule also expands restrictions to include other toxic compounds in coatings, introduces enhanced enforceability measures, and revises language for greater clarity. The action fulfills Control Measure CTS-01 from the 2022 Air Quality Management Plan and is supported by a CEQA exemption determination, which confirms no significant environmental impact due to the availability of safer substitutes. The rule applies across the South Coast AQMD jurisdiction, including Orange, Los Angeles, Riverside, and San Bernardino counties, and is intended to reduce human exposure to hazardous substances without increasing overall VOC emissions. Regulatory compliance is the primary focus, with no federal procurement elements, financial values, contracting officer roles, packaging requirements, inspection protocols, or offeror certifications present in the documentation. The rule was approved on December 5, 2025, and public submissions were accepted through the district’s formal hearing process, with inquiries directed to designated agency contacts.
