The Environmental Protection Agency published a proposal Feb. 8 to tighten chromium emission limits from electroplating facilities. The agency also intends to reduce chlorine emissions from steel pickling facilities by no longer allowing hydrochloric acid regeneration plants to establish an alternative, site-specific chlorine concentration standard, according to supplemental proposed amendments to the national emissions standards for hazardous air pollutants.
The proposal is expected to reduce hexavalent chromium emissions by 208 pounds per year and chlorine emissions by 15 tons per year. The air toxics standards apply to 1,450 chromium electroplating facilities and 110 steel pickling facilities.
EPA signed the rule Jan. 27 and posted it on its website (21 DEN A-2, 2/2/12). EPA will accept comments through March 26 at http://www.regulations.gov/
in Docket No. EPA-HQ-OAR-2010-0600.
