Environmental Protection Agency August 22, 2022 – 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 May 1, 2022 to July 31, 2022.

The Environmental Protection Agency (EPA) is proposing a limited approval and limited disapproval of two revised rules and an approval of a rule recission to the South Coast Air Quality Management District (SCAQMD) portion of the California State Implementation Plan (SIP). These revisions concern emissions of volatile organic compounds (VOCs) from marine and pleasure craft coating operations and the coating of metals. The EPA previously proposed to fully approve these SIP revisions on the grounds that they satisfied the relevant requirements under the Clean Air Act (CAA or the Act). After the comment periods, the EPA identified a deficiency in the submittals that warrants a limited disapproval. Therefore, we are withdrawing our previously proposed approvals of these SIP revisions as they pertain to these rules, published in the Federal Register on May 20, 2021, and August 24, 2021, and now propose a limited approval and limited disapproval for these revisions into the California SIP.

The Environmental Protection Agency (EPA) is redesignating the Oakridge, Oregon nonattainment area to attainment for the 2006 24-hour fine particulate matter (PM2.5) National Ambient Air Quality Standard (NAAQS). The EPA is also approving a maintenance plan for the area that demonstrates continued compliance with the PM2.5 NAAQS through the year 2035, which Oregon submitted along with the redesignation request for inclusion into the Oregon State Implementation Plan (SIP). Additionally, the EPA finds adequate and is approving the PM2.5 motor vehicle emission budgets for the area. Finally, the EPA is approving additional control measures, because incorporation of these measures will strengthen the Oregon SIP and ensure PM2.5 emissions reductions in the Oakridge area. The EPA is taking these actions pursuant to the Clean Air Act (CAA or the Act).
