| 2012-20642 | National Emission Standards for Hazardous Air Pollutant Emissions: Hard and Decorative Chromium Electroplating and Chromium Anodizing Tanks; and Steel Pickling-HCl Process Facilities and Hydrochloric Acid Regeneration Plants | Rule | This action finalizes the residual risk and technology review conducted for the following source categories regulated under two national emission standards for hazardous air pollutants (NESHAP): hard and decorative chromium electroplating and chromium anodizing tanks, and steel pickling--HCl process facilities and hydrochloric acid regeneration plants. On October 21, 2010, EPA proposed amendments to these NESHAP under section 112(d)(6) and (f)(2) of the Clean Air Act. On February 8, 2012, EPA published a supplemental proposal with new analyses and results. For hard and decorative chromium electroplating and chromium anodizing tanks these final amendments addressing Clean Air Act (CAA) sections 112(d)(6) and (f)(2) include revisions to the emissions limits for total chromium; addition of housekeeping requirements to minimize fugitive emissions; and a requirement to phase-out the use of perfluorooctane sulfonic acid (PFOS) based fume suppressants. These requirements will provide greater protection for public health and the environment by reducing emissions of hexavalent chromium (a known human carcinogen). In addition, as part of the October 2010 proposal, we proposed certain actions pursuant to CAA section 112(d)(2) and (3) for hard and decorative chromium electroplating and chromium anodizing tanks. For these sources, we are modifying and adding testing and monitoring, recordkeeping, and reporting requirements; and revisions to the regulatory provisions related to emissions during periods of malfunction. For steel pickling hydrochloric acid regeneration plants, we are finalizing our proposal to remove the alternative compliance method because we believe it is inconsistent with the requirements of CAA section 112(d)(2) and (3). This amendment will achieve reductions in chlorine emissions. Additionally, we are adding provisions to the Steel Pickling Facilities NESHAP requiring that the emission limits of the rule apply at all times, including during periods of startup, shutdown and malfunction. | 2012-09-19 | 2012 | 9 | https://www.federalregister.gov/documents/2012/09/19/2012-20642/national-emission-standards-for-hazardous-air-pollutant-emissions-hard-and-decorative-chromium | https://www.govinfo.gov/content/pkg/FR-2012-09-19/pdf/2012-20642.pdf | Environmental Protection Agency | 145 | This action finalizes the residual risk and technology review conducted for the following source categories regulated under two national emission standards for hazardous air pollutants (NESHAP): hard and decorative chromium electroplating and chromium... |
