Document Description
Rule 1107 limits emissions of volatile organic compounds (VOC) from metal coating operations. The primary objective of Proposed Amended Rule (PAR) 1107 is to partially implement control measure CTS-01: Further Emission Reductions From Coatings, Solvents, Adhesives, and Lubricants of the 2022 Air Quality Management Plan to phase out the use of para-Chlorobenzotrifluoride (pCBtF) and tert-Butyl Acetate (t-BAc) in metal parts and products coatings due to toxicity concerns. PAR 1107 includes: 1) a prohibition for the manufacture, sale, and use of coatings with more than trace levels of pCBtF and t-BAc at future effective dates; 2) sell-through and use-through provisions to ensure that manufacturers, distributors, and end users are provided with adequate time to transition to products without pCBtF and/or t-BAc; 3) prohibitions of other toxic compounds in coatings; 4) new provisions to enhance enforceability; and 5) revisions for clarity. The primary benefit of phasing out pCBtF and t-BAc is the reduced risk of exposure to these toxic chemicals by workers, nearby receptors and the public.

The proposed project is located within the South Coast Air Quality Management District’s (South Coast AQMD) jurisdiction, which includes the four-county South Coast Air Basin (all of Orange County and the non-desert portions of Los Angeles, Riverside, and San Bernardino counties), and the Riverside County portion of the Salton Sea Air Basin and the non-Palo Verde, Riverside County portion of the Mojave Desert Air Basin.

Reasons for Exemption
South Coast AQMD, as Lead Agency, has reviewed the proposed project pursuant to: 1) CEQA Guidelines Section 15002(k) – General Concepts, the three-step process for deciding which document to prepare for a project subject to CEQA; and 2) CEQA Guidelines Section 15061 – Review for Exemption, procedures for determining if a project is exempt from CEQA. It can be seen with certainty that there is no possibility that the proposed project (PAR 1107) may have a significant adverse effect on the environment because: 1) no change in VOC emissions is expected relative to baseline conditions; 2) some alternative compliant formulations that do not contain pCBtF and/or t-BAc are commercially available; 3) additional time is provided for reformulating metal coatings if needed; 4) manufacturer’s reformulation efforts are expected to occur using existing equipment and processes without the need for physical modifications to existing equipment; and 5) the sell-through and use-through provisions will prevent stranded assets and the generation of waste by ensuring that manufacturers, distributors, and end users have sufficient time to find suitable replacements. Therefore, the proposed project is exempt from CEQA pursuant to CEQA Guidelines Section 15061(b)(3) – Common Sense Exemption.
