Title: National Emission Standards for Hazardous Air Pollutants: Integrated Iron and Steel Manufacturing Facilities Residual Risk and Technology Review 
Abstract:

This final rule will address the Agency's residual risk and technology review (RTR) of the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Integrated Iron and Steel Manufacturing Facilities. The Iron and Steel Manufacturing Facilities NESHAP, subpart FFFFF, was promulgated pursuant to section 112(d) of the Clean Air Act (CAA) on May 20, 2003, and subsequently amended on July 13, 2006. The NESHAP established emission limitations and/or work practice requirements based on maximum achievable control technology (MACT) for controlling emissions of hazardous air pollutants (HAP) from iron-making blast furnaces; steel-making oxygen furnaces; ancillary operations, such as ladling, hot metal transfer, skimming, and desulfurization; and sinter plants. The HAP emitted from iron and steel sources include metal HAP (all sources) and volatile HAP (sinter plant only). This action implements the residual risk review requirements of CAA section 112(f)(2) and the technology review requirements of CAA section 112(d)(6). The statute directs the EPA to promulgate emission standards under CAA 112(f)(2), within 8 years after the MACT standards were established, if such standards are required to ensure the risks due to HAP emissions from these facilities are acceptable and that the NESHAP provides an ample margin of safety to protect public health or to prevent, taking relevant factors into account, an adverse environmental effect. CAA section 112(d)(6) requires the EPA to review and revise the MACT standards as necessary, taking into account developments in practices, processes, and control technologies, no less often than every 8 years. Pursuant to a court order, the EPA is obligated to complete the final action by March 13, 2020. While conducting the RTR, the EPA also might consider possible options to address certain issues raised in Sierra Club's March 26, 2004, petition for administrative reconsideration.

On August 16, 2019, the EPA proposed amendments to NESHAP for Integrated Iron and Steel Manufacturing Facilities. This proposal presents the results of the RTR conducted as required under the 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 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.
