Environmental Protection Agency July 31, 2023 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is planning to submit an information collection request (ICR), ``Information Collection Request (ICR) for On-Highway Motorcycle Certification and Compliance Program'' (EPA ICR Number 2535.03, OMB Control Number 2060- 0710) to the Office of Management and Budget (OMB) for review and approval in accordance with the Paperwork Reduction Act. Before doing so, EPA is soliciting public comments on specific aspects of the proposed information collection as described below. This is a proposed extension of the ICR, which is currently approved through October 31, 2023. An Agency may not conduct or sponsor and a person is not required to respond to a collection of information unless it displays a currently valid OMB control number.

The U.S. Environmental Protection Agency (EPA) is proposing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Integrated Iron and Steel Manufacturing Facilities, as required by the Clean Air Act (CAA). To complete the required CAA section 112(d)(6) technology review promulgated on July 13, 2020, the EPA is proposing standards to regulate HAP emissions from five unmeasured fugitive and intermittent particulate (UFIP) sources, some of which are also referred to as ``fugitive'' sources, that are currently not regulated by the NESHAP, as follows: Bell Leaks, Unplanned Bleeder Valve Openings, Planned Bleeder Valve Openings, Slag Pits, and Beaching. Also, for sinter plants we are proposing standards for the following five currently unregulated HAP: carbonyl sulfide (COS), carbon disulfide (CS2), mercury (Hg), hydrochloric acid (HCl), and hydrogen fluoride (HF); for blast furnace (BF) stoves and basic oxygen process furnaces (BOPFs), we are proposing standards for the following three unregulated pollutants: total hydrocarbons (THC), HCl, and dioxins/furans (D/F); and for BFs, we are proposing standards for the following two unregulated pollutants: THC and HCl. As an update to the technology review, we are proposing to revise the current BOPF shop fugitive 20 percent opacity limit to a 5 percent opacity limit and require specific work practices; revise the current BF casthouse fugitive 20 percent opacity limit to a 5 percent opacity limit; and revise the current standards for D/F and polycyclic hydrocarbon (PAH) for sinter plants. We are also proposing a fenceline monitoring requirement for chromium (Cr), including a requirement that if a monitor exceeds the proposed Cr action level, the facility will need to conduct a root cause analysis and take corrective action to lower emissions. We solicit comments on all aspects of this proposed action.

The Environmental Protection Agency (EPA) is taking interim final action to stay, for emissions sources in Arkansas, Kentucky, Louisiana, Mississippi, Missouri, and Texas only, the effectiveness of the federal implementation plan (FIP) requirements established to address the obligations of these and other states to mitigate interstate air pollution with respect to the 2015 national ambient air quality standards (NAAQS) for ozone (the Good Neighbor Plan). The EPA is also revising certain other regulations to ensure that sources in these states will continue to be subject to previously established requirements to mitigate interstate air pollution with respect to other ozone NAAQS while the Good Neighbor Plan's requirements are stayed. These revisions will also ensure that the stay is limited to requirements for which the EPA does not currently have authority to implement a FIP pending judicial review. The stay and the associated revisions to other regulations are being issued in response to judicial orders that partially stay, pending judicial review, a separate, earlier EPA action which disapproved certain state implementation plan (SIP) revisions submitted by these and other states. Finally, for states for which the Good Neighbor Plan's requirements are not being stayed, the EPA is revising three near-term deadlines that are incorrect as published in the Good Neighbor Plan.
