Environmental Protection Agency December 30, 2019 – Federal Register Recent Federal Regulation Documents

As required under section 6(b) of the Toxic Substances Control Act (TSCA) and implementing regulations, EPA is designating 20 chemical substances as High-Priority Substances for risk evaluation. This document identifies the final designations and Agency rationale for the chemical substances and provides instructions on how to access the chemical-specific information, analysis and basis used by EPA to support final designations for the chemical substances. A designation of a substance as a High-Priority Substance is not a finding of unreasonable risk. However, the designation of these chemical substances as high-priority substances constitutes the initiation of the risk evaluations on the substances.

Notice is hereby given that a reissuance of an exemption to the Land Disposal Restrictions, under the 1984 Hazardous and Solid Waste Amendments to the Resource Conservation and Recovery Act, has been granted to GLCC for two Class I hazardous waste injection wells located at their El Dorado, Arkansas facility. The company has adequately demonstrated to the satisfaction of the Environmental Protection Agency (EPA) by the petition reissuance application and supporting documentation that, to a reasonable degree of certainty, there will be no migration of hazardous constituents from the injection zone for as long as the waste remains hazardous. This final decision allows the underground injection by GLCC of the specific restricted hazardous wastes identified in this exemption reissuance request, into Class I hazardous waste injection wells WDW-5 and WDW-6 until December 31, 2026, unless the EPA moves to terminate this exemption. Additional conditions included in this final decision may be reviewed by contacting the EPA Region 6 Ground Water/UIC Section. A public notice was issued October 7, 2019, and the public comment period closed on November 22, 2019, and no comments were received. This decision constitutes final Agency action and there is no Administrative appeal.

The Clean Air Act (CAA) requires each State Implementation Plan (SIP) to contain adequate provisions prohibiting emissions that will have certain adverse air quality effects in other states. The Environmental Protection Agency (EPA or Agency) is proposing to approve State Implementation Plan (SIP) revisions from Alabama, Florida, Georgia, North Carolina, South Carolina, and Tennessee (collectively, Southeast States) addressing the Clean Air Act (CAA or Act) good neighbor interstate transport infrastructure SIP requirements for the 2015 8-hour ozone National Ambient Air Quality Standard (NAAQS). EPA is proposing to approve the submission as meeting the requirement that each SIP contain adequate provisions to prohibit emissions that will significantly contribute to nonattainment or interfere with maintenance of the 2015 ozone NAAQS in any other state.

The Environmental Protection Agency (EPA) is finalizing action on a revision to the Yolo-Solano Air Quality Management District (YSAQMD or ``the District'') portion of the California State Implementation Plan (SIP) to approve a rule governing issuance of permits for stationary sources emitting fine particulate matter (PM2.5) and PM2.5 precursors, including review and permitting of major sources and major modifications under part D of title I of the Clean Air Act (CAA or ``the Act''). Specifically, the approval pertains to YSAQMD Rule 3.25, ``Federal New Source Review for New and Modified Major PM2.5 Sources.''
