Document Description
Proposed Amended Rule 1469 (PAR 1469) implements the 2023 California Air Resources Board (CARB) amendments to the Airborne Toxic Control Measure for Chromium Plating and Chromic Acid Anodizing Operations (Chrome ATCM) including the phase out of hexavalent chromium used for decorative chrome operations and functional chrome operations dependent on findings from pending technology reviews to be conducted by CARB. The Chrome ATCM also prohibits new hexavalent chromium electroplating or chromic acid anodizing facilities and includes enhanced best management practices and housekeeping requirements. In addition, PAR 1469 includes clarifications of existing rule requirements, changes to source test deadlines, and procedures that assist in rule implementation. Upon full implementation, PAR 1469 is projected to reduce hexavalent chromium emissions by approximately 6.56 pounds per year which will reduce risk of exposure of this toxic chemical to workers, nearby receptors, and the public.

Reasons for Exemption
South Coast AQMD, as Lead Agency, has reviewed the proposed project (PAR 1469) 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. Because PAR 1469 incorporates provisions from the Chrome ATCM, an existing regulation whose environmental impacts were analyzed in the Final Environmental Analysis for the Proposed Amendments to the Airborne Toxic Control Measure for Chromium Electroplating and Chromic Acid Anodizing Operations which was certified by CARB on May 25, 2023, and because PAR 1469 includes other requirements which are separate from the Chrome ATCM and do not require physical modifications, it can be seen with certainty that there is no possibility that the proposed project may have a significant adverse effect on the environment. Therefore, the proposed project is exempt from CEQA pursuant to CEQA Guidelines Section 15061(b)(3) – Common Sense Exemption.
