Adequacy Status of Motor Vehicle Budgets in Submitted Eight-Hour Ozone Attainment Plan for the Phoenix-Mesa Nonattainment Area for Transportation Conformity Purposes; Arizona
In this notice, EPA is notifying the public that the Agency has found that the motor vehicle emissions budgets in the submitted Eight-Hour Ozone Plan for the Maricopa Nonattainment Area (June 2007) (``2007 MAG Eight-Hour Ozone Plan'') are adequate for transportation conformity purposes. The 2007 MAG Eight-Hour Ozone Plan was submitted to EPA on June 15, 2007 by the Arizona Department of Environmental Quality as a revision to the Arizona state implementation plan. As a result of our finding, the Maricopa Association of Governments (MAG) and the Federal Highway Administration must use the motor vehicle emissions budgets from the submitted eight-hour ozone attainment plan for future conformity determinations.
Delegation of Authority to the States of Iowa, Kansas, Missouri, and Nebraska for New Source Performance Standards (NSPS); National Emission Standards for Hazardous Air Pollutants (NESHAP); and Maximum Achievable Control Technology (MACT) Standards
The states of Iowa, Kansas, Missouri, and Nebraska have submitted updated regulations for delegation of EPA authority for implementation and enforcement of NSPS, NESHAP, and MACT standards. The submissions cover new EPA standards and, in some instances, revisions to standards previously delegated. EPA's review of the pertinent regulations shows that they contain adequate and effective procedures for the implementation and enforcement of these Federal standards. This action informs the public of delegations to the above-mentioned agencies.
Clean Water Act Section 303(d): Availability of 34 Total Maximum Daily Loads (TMDL) in Louisiana
This notice announces the availability for comment of the administrative record files for 34 TMDLs and the calculations for these TMDLs prepared by EPA Region 6 for waters listed in the Red, Sabine, and the Terrebonne Basins of Louisiana, under section 303(d) of the Clean Water Act (CWA). These TMDLs were completed in response to a court order in the lawsuit styled Sierra Club, et al. v. Clifford, et al., No. 96-0527, (E.D. La.).
Regulation of Fuels and Fuel Additives: Modification of Baselines for Gasoline Produced or Imported for Use in Hawaii, Alaska and U.S. Territories
This final rule allows refiners and importers who produce or import conventional gasoline for use in Alaska, Hawaii, the Commonwealth of Puerto Rico and the Virgin Islands the option to change the way in which they calculate emissions from such gasoline for purposes of establishing their conventional gasoline anti-dumping and toxics performance baselines and determining compliance with their baselines. Specifically, this final rule allows refiners and importers of gasoline sold for use in these areas to petition EPA to modify their baselines to replace the anti-dumping statutory baseline with the single seasonal statutory baseline that is most appropriate to the regional climate, and to use the seasonal component of the Complex Model that is most appropriate to the regional climate to calculate individual baselines and annual average emissions. The rule allows refiners and importers to petition EPA to use the summer statutory baseline and the summer Complex Model for all baseline and compliance calculations for conventional gasoline produced or imported for use in Hawaii, Puerto Rico and the Virgin Islands, and allows refiners and importers to petition EPA to use the winter statutory baseline and the winter Complex Model for all baseline and compliance calculations for conventional gasoline produced or imported for use in Alaska. EPA is taking this action to address certain inconsistencies in the fuels regulations which may have significant unintended negative impacts on refiners and importers who produce or import gasoline for these areas.
