EPA also requested additional information on how the plan would meet the federal reserved water rights for the Black Canyon of the Gunnison National Park. Rating EC2.

This regulation establishes tolerances for combined residues of indoxacarb and its metabolites and degradates, to be determined by measuring only indoxacarb and its R-enantiomer, in or on beet, garden, roots; beet, garden, tops; and bushberry subgroup 13-07B. Interregional Research Project Number 4 (IR-4) requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA).

EPA is proposing to approve state implementation plan (SIP) revisions submitted by the State of California on June 15, 2004 and February 3, 2009, relating to reformulated gasoline (RFG) and diesel fuel sold or supplied as motor vehicle fuels in California. The revisions relating to RFG include California Phase 3 RFG (CaRFG3) regulations, correction of errors and streamlined requirements for compliance with and enforcement of the CaRFG3 standards, and an update to the State's predictive model to mitigate permeation emissions associated with the use of ethanol as a fuel additive. The revisions relating to diesel fuel establish test methods for determining the aromatic hydrocarbon content in diesel fuel and lower the maximum allowable sulfur content for motor vehicle diesel fuel.

EPA is proposing to approve part of two Beaumont-Port Arthur (BPA) State Implementation Plan (SIP) revisions that were submitted separately by the State of Texas on October 15, 2005. The revisions being proposed pertain to volatile organic compound (VOC) control requirements for batch processing and ship building and ship repair, and also to Reasonably Available Control Technology (RACT) requirements, for the Beaumont/Port Arthur (BPA) 1-hour ozone serious nonattainment area. In today's action, EPA is proposing to approve: The State's changes to the batch process rules and the shipbuilding and ship repair rules that lower the threshold for affected sources of VOC emissions to the serious area requirements of 50 tons per year (tpy), and the State's demonstration that the BPA area meets RACT requirements for sources of VOC and NOX emissions for the 1-hour ozone standard. These revisions meet statutory and regulatory requirements, and are consistent with EPA's guidance. The EPA is approving the revisions pursuant to section 110 and part D of the Federal Clean Air Act (the Act).
