Environmental Protection Agency August 9, 2024 – Federal Register Recent Federal Regulation Documents

The Toxic Substances Control Act (TSCA) requires EPA to publish in the Federal Register a statement of its findings after its review of certain TSCA submissions when EPA makes a finding that a new chemical substance or significant new use is not likely to present an unreasonable risk of injury to health or the environment. Such statements apply to premanufacture notices (PMNs), microbial commercial activity notices (MCANs), and significant new use notices (SNUNs) submitted to EPA under TSCA. This document presents statements of findings made by EPA on such submissions during the period from June 1, 2024, to June 30, 2024.

The Environmental Protection Agency (EPA) is proposing to partially approve and partially disapprove the Wisconsin regional haze state implementation plan (SIP) revision submitted by the Wisconsin Department of Natural Resources (Wisconsin or WDNR) on July 30, 2021. In the alternative, EPA is proposing to approve the Wisconsin regional haze SIP in its entirety so long as WDNR provides evidence to EPA that operation of coal-fired cyclone Boiler B26 at the Ahlstrom- Munksj[ouml]Rhinelander Mill has permanently ceased. In the event evidence is provided confirming the federally enforceable and permanent shutdown of the Ahlstrom-Munksj[ouml]Rhinelander Mill Boiler B26, EPA proposes to find that Wisconsin's SIP submission addresses the requirement that states must periodically revise their long-term strategies for making reasonable progress towards the national goal of preventing any future, and remedying any existing, anthropogenic impairment of visibility, including regional haze, in mandatory Class I Federal areas, and also addresses other applicable requirements for the second implementation period of the regional haze program. EPA is taking this action pursuant to sections 110 and 169A of the Clean Air Act (CAA).
