chrome -- Materials for Chrome Plating ATCM Public Workshop Posted: 09 Jan 2013 14:45:52
The Air Resources Board (ARB/Board) staff is holding a public workshop on proposed amendments to the Airborne Toxic Control Measure for Chromium Plating and Chromic Acid Anodizing Facilities (Chrome Plating ATCM). The Chrome Plating ATCM workshop agenda and staff presentation are now available on our website at http://www.arb.ca.gov/toxics/chrome/chrome.htm for your review and download. As a reminder, this workshop will be held at the following time and location: Date: January 10, 2013 Time: 10:00 am to 12:00 p.m. Location: Conference Room 550 Address: Cal/EPA Headquarters Building 1001 “I” Street, 5th Floor Sacramento, California 95814 Background: The ARB identified hexavalent chromium as a toxic air contaminant (TAC) in January 1986. The Board found, based on epidemiological and animal studies, that hexavalent chromium should be considered a human carcinogen for which there is no safe threshold exposure level. In 1988, an ATCM was adopted to reduce hexavalent chromium emissions from both decorative and hard chrome plating facilities, as well as chromic acid anodizing operations (Chrome Plating ATCM). This measure reduced overall emissions from these facilities by 97 percent. In 1998, the Chrome Plating ATCM was amended to establish equivalency with United States Environmental Protection Agency (U.S. EPA) standards. In an effort to further protect the public, amendments to the Chrome Plating ATCM were presented and approved by the Board on December 7, 2006. These amendments were subsequently adopted on August 9, 2007, and became legally effective on October 24, 2007. The adopted amendments set forth the most stringent emission control requirements in the nation. On September 19, 2012, the U.S. EPA published amendments to the National Emission Standards for Hazardous Air Pollutants – Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks. Information about these amendments can be found in the Federal Register at the following website: http://www.gpo.gov/fdsys/pkg/FR-2012-09-19/pdf/2012-20642.pdf. U.S. EPA actions amended the emission limits, surface tension requirements, and phased out the use of perfluorinated octane sulfonate (PFOS) in fume suppressants. As a result, ARB is proposing to make amendments to the Chrome Plating ATCM to align with U.S. EPA’s amended rule. The primary changes we are proposing are to revise the surface tension limits and phase out the use of PFOS in fume suppressants.
