| 2014-27497 | National Emissions Standards for Hazardous Air Pollutants: Secondary Aluminum Production | Proposed Rule | This action supplements our notice of proposed rulemaking for the national emissions standards for hazardous air pollutants (NESHAP) for secondary aluminum production, which was published in the Federal Register on February 14, 2012. In that action, the Environmental Protection Agency (EPA) proposed decisions concerning the residual risk and technology review for the Secondary Aluminum Production source category and proposed amendments to correct and clarify rule requirements. This supplemental proposal presents a revised risk review (including a revised inhalation risk assessment, a refined multipathway risk assessment, and an updated ample margin of safety analysis) and a revised technology review for the Secondary Aluminum Production source category. Similar to the 2012 proposal, we found risks due to emissions of air toxics to be acceptable from this source category and we identified no cost effective controls under the updated ample margin of safety analysis or the technology review to achieve further emissions reductions. Therefore, we are proposing no revisions to the numeric emission standards based on these revised analyses. However, this supplemental proposal supplements and modifies several of the proposed technical corrections and rule clarifications that were originally presented in the February 14, 2012 proposal; withdraws our previous proposal to include affirmative defense provisions in the regulation; proposes alternative compliance options for the operating and monitoring requirements for sweat furnaces; and provides a revised cost analysis for compliance testing. This action, if finalized, would result in improved monitoring, compliance and implementation of the rule. | 2014-12-08 | 2014 | 12 | https://www.federalregister.gov/documents/2014/12/08/2014-27497/national-emissions-standards-for-hazardous-air-pollutants-secondary-aluminum-production | https://www.govinfo.gov/content/pkg/FR-2014-12-08/pdf/2014-27497.pdf | Environmental Protection Agency | 145 | This action supplements our notice of proposed rulemaking for the national emissions standards for hazardous air pollutants (NESHAP) for secondary aluminum production, which was published in the Federal Register on February 14, 2012.
