Environmental Protection Agency July 19, 2021 – Federal Register Recent Federal Regulation Documents

This action announces the Environmental Protection Agency (EPA) approval of the request by Rohm and Haas Chemicals LLC, a subsidiary of The Rohm and Haas Chemical Company (Rohm and Haas), under the Clean Air Act (CAA) for an alternative means of emission limitation (AMEL) for the Standards of Performance for Volatile Organic Liquid Storage Vessels. The AMEL applies to a proposed new vinyl acetate bulk storage tank to be used at its chemical plant in Kankakee, Illinois. The EPA received no adverse comments on the request. This approval document specifies the operating conditions and monitoring, recordkeeping, and reporting requirements that this facility must follow to demonstrate compliance with the approved AMEL.

Notice is hereby given that the Environmental Protection Agency (EPA) has tentatively approved the State of Wisconsin's revisions to the State's Public Water System Supervision (PWSS) Program under the federal Safe Drinking Water Act (SDWA) for adoption of the federal Ground Water Rule, as well as revisions to the federal Surface Water Treatment Rule under the Long Term 2 Enhanced Surface Water Treatment Rule. The EPA has determined that the State's PWSS program regulations and the revisions thereto are no less stringent than the corresponding federal regulations for the Ground Water Rule and the Long Term 2 Enhanced Surface Water Treatment Rule. Therefore, the EPA intends to approve this revision to the State of Wisconsin's Public Water System Supervision Program, thereby giving the Wisconsin Department of Natural Resources primary enforcement responsibility for the Ground Water Rule and the Long Term 2 Enhanced Surface Water Treatment Rule. This approval action does not extend to public water systems in Indian Country. By approving this revision, the EPA does not intend to affect the rights of federally recognized Indian Tribes in Wisconsin, nor does it intend to limit existing rights of the State of Wisconsin.

Through this supplemental notice of proposed rulemaking (``supplemental proposal'' or ``SNPRM''), the Environmental Protection Agency (EPA) is supplementing its proposed approval of state implementation plan (SIP) submissions from Florida, Georgia, North Carolina, and South Carolina (four Southeastern States), addressing the Clean Air Act (CAA or Act) interstate transport requirements for the 2015 8-hour ozone National Ambient Air Quality Standard (NAAQS or standard). Specifically, EPA is proposing to rely on updated analysis using a 2021 analytic year to support the proposed finding that each state's implementation plan contains adequate provisions to prohibit emissions that will significantly contribute to nonattainment or interfere with maintenance of the 2015 ozone NAAQS in any other state.
