Environmental Protection Agency June 7, 2019 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is proposing to reconsider the nonattainment designation under the Clean Air Act (CAA) for the Williamson County, Illinois area for the 2010 1-hour sulfur dioxide (SO2) primary national ambient air quality standard (NAAQS). On June 30, 2016, the EPA Administrator signed a final action that designated the Williamson County, Illinois area as nonattainment based on a review of available information. On September 12, 2016, Southern Illinois Power Cooperative (SIPC), the owner of the largest source of SO2 emissions in the area (the Marion Power Station), submitted to the EPA an updated modeling analysis that characterized SO2 air quality in the area at the time of the final designation action. The EPA has reviewed that modeling and concludes the available information demonstrates that, as of the date of the Administrator's signature on the final action, the Williamson County, Illinois area was not violating the 2010 1-hour SO2 NAAQS and was not contributing to a NAAQS violation in a nearby area. Therefore, the EPA is proposing to change the initial designation of Williamson County, Illinois, from nonattainment to attainment/ unclassifiable.

The U.S. Virgin Islands (USVI) has requested that EPA consider approving its Resource Conservation and Recovery Act (RCRA) Subtitle D municipal solid waste landfills (MSWLF) Permit Program and with this action, EPA is proposing a Tentative Determination of Adequacy of the USVI MSWLF Permit Program. Although RCRA does not require EPA to hold a hearing on any determination to approve a State/Tribe's MSWLF program, the Region has scheduled three public hearings on this tentative determination. Details appear below in the DATES section.

This document announces the Agency's receipt of several initial filings of pesticide petitions requesting the establishment or modification of regulations for residues of pesticide chemicals in or on various commodities.

On May 15, 2019, the Environmental Protection Agency published a final rule which added seven new sites to the National Priorities List (NPL) and changed the name of an NPL site. That document inadvertently contained a typographical error, citing Table 1 (General Superfund Section) in the instructions to make the site name change rather than Table 2 (Federal Facilities Section). This document corrects the final rule.
