The Environmental Protection Agency (EPA) is proposing to approve state implementation plan (SIP) revisions submitted by California to address Clean Air Act (CAA or ``Act'') requirements for the 2006 24-hour fine particulate matter (PM2.5) national ambient air quality standards (NAAQS or ``standards'') in the Los Angeles-South Coast air basin (South Coast) Serious PM2.5 nonattainment area. The EPA is also proposing to approve 2017 and 2019 motor vehicle emissions budgets for transportation conformity purposes and inter-pollutant trading ratios for use in transportation conformity analyses.

The Environmental Protection Agency (EPA) is notifying the public that we have received from Indiana requests for withdrawals of the previously approved state plans and notification of negative declarations for Commercial and Industrial Solid Waste Incineration (CISWI) units and Sewage Sludge Incineration (SSI) units. The Indiana Department of Environmental Management (IDEM) submitted its CISWI withdrawal and negative declaration by letter dated July 31, 2017 and its SSI withdrawal and negative declaration by letter dated July 31, 2017. IDEM notified EPA in its negative declaration letters that there are no CISWI or SSI units subject to the requirements of the Clean Air Act (Act) currently operating in Indiana.

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 Phillips 66 Company for a Class I hazardous waste injection well located at their Borger, Texas refinery. The company has adequately demonstrated to the satisfaction of the 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 Phillips 66 Company of the specific restricted hazardous wastes identified in this exemption reissuance request, into Class I hazardous waste injection well WDW-325 until April 1, 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 July 13, 2018, and the public comment period closed on August 30, 2018, and no comments were received. This decision constitutes final Agency action and there is no Administrative appeal. This decision may be reviewed/appealed in compliance with the Administrative Procedure Act.

Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is proposing to approve portions of two Texas State Implementation Plan (SIP) submittals that pertain to the good neighbor and interstate transport requirements of the CAA with respect to the 1997 ozone National Ambient Air Quality Standards (NAAQS). The good neighbor provision requires each state, in its SIP, to prohibit emissions that will significantly contribute to nonattainment, or interfere with maintenance, of a NAAQS in other states. In this action, EPA is proposing to approve the Texas SIP submittals as having met the requirements of the good neighbor provision for the 1997 ozone NAAQS in accordance with section 110 of the CAA.

EPA is promulgating significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for 26 chemical substances which were the subject of premanufacture notices (PMNs). The chemical substances are subject to Orders issued by EPA pursuant to sections 5(e) and 5(f) of TSCA. This action requires persons who intend to manufacture (defined by statute to include import) or process any of these 26 chemical substances for an activity that is designated as a significant new use by this rule to notify EPA at least 90 days before commencing that activity. The required notification initiates EPA's evaluation of the intended use within the applicable review period. Persons may not commence manufacture or processing for the significant new use until EPA has conducted a review of the notice, made an appropriate determination on the notice, and has taken such actions as are required with that determination.
