Environmental Protection Agency August 17, 2018 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is proposing approval of two State Implementation Plan (SIP) revisions submitted by the State of Colorado. The revisions involve amendments to Colorado's Regulation Number 11, ``Motor Vehicle Emissions Inspection Program.'' The revisions enhance the use of Regulation Number 11's Clean Screen Program, allow self-inspecting vehicle fleets to use the On-Board Diagnostics (OBD) testing procedure, provide corrections to the Low Emitter Index (LEI) component of the Clean Screen Program, clarify existing provisions, correct administrative errors, delete obsolete language, establish inspection procedures for when emission control equipment tampering is detected, and make several other minor associated revisions. These actions are being taken under section 110 of the Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD or ``District'') portion of the California State Implementation Plan (SIP). These revisions concern the District's 2014 demonstration regarding Reasonably Available Control Technology (RACT) requirements for the 2008 8-hour ozone National Ambient Air Quality Standard (NAAQS). We are also taking final action to approve into the California SIP the following documents that help support the District's RACT demonstration: SJVUAPCD's supplement to its 2014 RACT SIP demonstration, which contains SJVUAPCD's negative declarations where the District concludes it has no sources subject to certain Control Techniques Guidelines (CTG) documents and relevant permit conditions to implement RACT level requirements for J.R. Simplot's Nitric Acid plant in Helm, California (CA); and SJVUAPCD's 2016 Ozone Plan for the 2008 8-Hour Ozone StandardChapter 3.4 and Appendix C only. We are approving local SIP revisions to demonstrate that RACT is implemented as required under the Clean Air Act (CAA or the ``the Act'').

EPA is promulgating significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for 27 chemical substances which were the subject of premanufacture notices (PMNs). The chemical substances are subject to Orders issued by EPA pursuant to section 5(e) of TSCA. This action requires persons who intend to manufacture (defined by statute to include import) or process any of these 27 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.
