Proposed Amended Rule 1469 – Hexavalent Chromium Emissions from Chromium Electroplating and Chromic Acid Anodizing Operations

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.
