Chromium uses in ww22/12/2024 “CARB’s strategy is to reduce air pollution in these communities,” the agency says. CARB says AB 6174 requires them to enact a statewide strategy to reduce emissions of TACs in communities that experience disproportionate burdens from exposure to air pollutants. In 2017, CARB established the Community Air Protection Program (CAPP) in response to a state assembly bill that required more stringent air quality measures. Ban Spawned from Community Air Protection Program Rule 1469 was most recently amended in 2021 and included additional measures to reduce fugitive emissions. In 1998, South Coast Air Quality Management District’s (SCAQMD) Rule 1469, Hexavalent Chromium Emissions from Chrome Plating and Chromic Acid Anodizing Operations, was adopted. What we’re asking for is a science-based rule like 1469 that uses control equipment and things like that.” “Strategy-wise, we’ve tried to have meaningful discussions with CARB staff to address these points, but it’s fallen on deaf ears so far,” Leiker says. Leiker says the MFAC has tried numerous times over the past several years to work with CARB on the proposed amendments, and the board has visited over 22 shops since 2017 to see how those shops are mitigating any potential risks associated with hex chrome. “A co-benefit of the proposed amendments is the eventual elimination of all sources of perfluoroalkyl and polyfluoroalkyl substances (PFAS) from decorative chrome plating and functional plating facilities.” “The proposed amendments are designed to reduce the harmful hexavalent chromium emissions to the lowest level possible (e.g., zero or near-zero) and decrease cancer risk in California communities near decorative and functional plating sources,” CARB says. The agency says that by banning these plating and anodizing facilities, they can also rid the state of possible PFAS issues, too. It’s flat-out misinformation.” Ban would Affect Over 100 ShopsĬARB says that the total number of facilities in operation currently that the ban would affect is 113, with 51 decorative chrome plating and 62 functional chrome plating facilities 36 hard chrome plating, and 26 chromic acid anodizing. They are skewing the numbers and basically taking what the numbers would be if none of us had control equipment or anything else in place. “They are saying our industry emits 10 pounds per year of hex chrome when it’s more like one pound or less. “The numbers they are using are incorrect,” he says. The amendments will also reduce the cumulative risk burden in overburdened and disadvantaged communities.”īut Leiker and the MFAC say that CARB is using faulty scientific evidence to ban an industry that is extremely vital to the California manufacturing industry, specifically the aerospace sector. “The proposed amendments will eliminate over time hexavalent chromium emissions and the associated health risks in communities located near chrome plating facilities. “All these chrome plating processes generate mists containing hexavalent chromium that is released into the surrounding air,” CARB says. 2 to help show that the plating and anodizing industry operates in a safe environment.ĬARB says the purpose of the amendments is to eliminate highly toxic hex chrome exposures in communities where these operations exist. He is also asking others in the finishing industry in the U.S. “This is a make-or-break effort for this issue,” says Leiker, who is asking MFAC members and non-members to attend the hearing. 1, 2039.īryan Leiker, Executive Director of the Metal Finishing Association of California, says the association members and its OEM customers will fight against these new rules and bans at the meeting. Phase out the use of hexavalent chromium in functional plating (hard plating and chromic acid anodizing) by Jan.Phase out the use of hexavalent chromium in decorative plating by Jan.1, 2026, for hard plating and chromic acid anodizing facilities that implement building enclosure, new emission limits, install controls on qualifying tanks, and new source testing. Ban any new chromium electroplating and chromic acid anodizing operations starting after Jan.The CARB panel will review staff recommendations on amendments to its Airborne Toxic Control Measure for chromium electroplating and chromic acid anodizing operations that include: The California Air Resources Board has set a January 27 public hearing on its plan to ban decorative and functional hexavalent chromium plating and anodizing operations in the state.
