Proposed Administrative Change for Thermal-Spraying Operations
On November 16-17, 2006, the California Air Resources Board (ARB or Board) will consider regulatory revisions that will clarify that certain types of "Thermal Spraying" are considered a metal-coating activity covered by the AB 2588 Air Toxics "Hot Spots" Program. This revision would only apply to thermal-spraying operations that use materials containing chromium or nickel. ARB anticipates that in most cases compliance with the "Airborne Toxic Control Measure to Reduce Emissions of Hexavalent Chromium and Nickel from Thermal Spraying" (ATCM) adopted by the Board in 2004 will satisfy the requirements of the "Hot Spots" Program.
California's AB 2588 Air Toxics "Hot Spots" Program helps identify facilities that emit toxic air contaminants and pose a public health risk. After high-risk facilities are identified, they must take actions to reduce their risk to acceptable levels.
