Environmental Protection Agency August 16, 2023 – Federal Register Recent Federal Regulation Documents

This document supplements the proposed ``State of Louisiana Underground Injection Control Program; Class VI Program Revision Application'' rule of May 4, 2023, to approve a revision to the State's Safe Drinking Water Act (SDWA) section 1422 UIC program to include Class VI injection well primary enforcement responsibility (primacy). On June 30, 2023, the Louisiana Department of Natural Resources (LDNR) supplemented its Class VI primacy application to include Act No. 378 (HB 571), which revised portions of Louisiana law relevant to LDNR's application. On June 14, 2023, Act No. 378 was signed into law and went into effect during the comment period for EPA's proposal. This document presents and requests public comment on LDNR's supplement to its application, which was not available in the docket EPA-HQ-OW-2023-0073 at the time of the Environmental Protection Agency's (EPA) May 4, 2023, proposal.

The Environmental Protection Agency (EPA) published a notice in the Federal Register on August 1, 2023, requesting comments on a prospective administrative settlement agreement for response action between the United States, the State of Colorado, and Four Points Funding, LLC, at the Central City/Clear Creek Superfund Site in Clear Creek County, Colorado. This notice corrects errors contained in the document.

The Environmental Protection Agency has submitted an information collection request (ICR), Evaluating End User Satisfaction of EPA's Research Products (EPA ICR Number 2593.02, OMB Control Number 2080-0085) to the Office of Management and Budget (OMB) for review and approval in accordance with the Paperwork Reduction Act (PRA). This is a proposed extension of the ICR, which is currently approved through August 31, 2023. Public comments were previously requested via the Federal Register on December 19, 2022, during a 60-day comment period. This notice allows for an additional 30 days for public comments.

The Environmental Protection Agency (EPA) announces the deletion of three sites and the partial deletion of eight sites from the Superfund National Priorities List (NPL). The NPL, created under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended, is an appendix of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). The EPA and the states, through their designated State agencies, have determined that all appropriate response actions under CERCLA have been completed. However, this deletion does not preclude future actions under Superfund.

This regulation establishes tolerances for residues of fluxapyroxad in or on avocado; stevia, dried leaves; and stevia, fresh leaves and revises the tolerance for residues of fluxapyroxad in or on coffee, green bean. Interregional Project Number 4 (IR-4) and BASF Corporation requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA).

The Environmental Protection Agency (EPA) is proposing amendments to the National Emissions Standards for Hazardous Air Pollutants (NESHAP) for Coke Ovens: Pushing, Quenching, and Battery Stacks (PQBS) source category, and the NESHAP for the Coke Oven Batteries (COB) source category. This proposal presents the results of the residual risk and technology review (RTR) conducted as required under the Clean Air Act (CAA) for the PQBS source category, and the periodic technology review for the COB source category, also required under the CAA. The EPA is proposing that risks due to emissions of hazardous air pollutants (HAP) from the PQBS source category are acceptable and that the current NESHAP provides an ample margin of safety to protect public health. Under the technology review for PQBS NESHAP, we are proposing there are no developments in practices, processes or control technologies that necessitate revision of standards for this source category. Under the technology review for the COB source category, the EPA is proposing amendments to the NESHAP to lower the limits for leaks from doors, lids, and offtakes to reflect improvements in technology to minimize emissions. We also are proposing a requirement for fenceline monitoring for benzene (as a surrogate for coke oven emissions) and a requirement to conduct root cause analysis and corrective action upon exceeding an action level. In addition, we are proposing: (1) new standards for several unregulated HAP or sources of HAP at facilities subject to PQBS NESHAP; (2) the removal of exemptions for periods of startup, shutdown, and malfunction consistent with a 2008 court decision, and clarifying that the standards apply at all times for both source categories; and (3) the addition of electronic reporting for performance test results and compliance reports. We solicit comments on all aspects of this proposed action.
