The Environmental Protection Agency (EPA) is proposing amendments to the National Emissions Standards for Hazardous Air Pollutants (NESHAP) for Integrated Iron and Steel Manufacturing Facilities. This proposal presents the results of the residual risk and technology review (RTR) conducted as required under the Clean Air Act (CAA). Based on the results of the EPA risk review, the Agency is proposing that risks due to emissions of air toxics are acceptable from this source category and that the current NESHAP provides an ample margin of safety to protect public health. Under the technology review, we are proposing there are no developments in practices, processes or control technologies that necessitate revision of the standards. Pursuant to granting a request to reconsider setting mercury standards in 2005, we are proposing an emissions standard for mercury based on limiting the amount of mercury in the metal scrap used by these facilities. We also are proposing: the removal of exemptions for periods of startup, shutdown, and malfunction (SSM) consistent with a 2008 court decision, and clarifying that the emissions standards apply at all times; the addition of electronic reporting of performance test results and compliance reports; and minor corrections and clarifications for a few other rule provisions. Finally, we are soliciting comment on unmeasured fugitive and intermittent emissions that have been identified as occurring at facilities in this source category and the cost and effectiveness of potential work practices that could be implemented to reduce emissions from these fugitive and intermittent sources.
The agency’s own summary, as published.
