Environmental Protection Agency July 14, 2006 – Federal Register Recent Federal Regulation Documents

EPA is proposing to approve State Implementation Plan (SIP) revisions submitted by the Commonwealth of Pennsylvania. These revisions pertain to additional nitrogen oxides (NOX) reductions that are required for the Commonwealth to support its approved attainment demonstration for the Philadelphia-Trenton- Wilmington one-hour ozone nonattainment area (the Philadelphia Area); NOX reductions from stationary internal combustion (IC) engines required to meet the NOX SIP Call Phase II (Phase II); and NOX reductions from cement kilns to meet the NOX SIP Call. The revisions also include provisions for emission credits for sources that generate zero-emission renewable energy. This action is being taken under the Clean Air Act (CAA or the Act).

EPA is approving a redesignation request and a State Implementation Plan (SIP) revision submitted by the State of West Virginia. This revision requests that EPA redesignate the Weirton nonattainment area (Weirton Area) to attainment for the national ambient air quality standards (NAAQS) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM-10), and concurrently requests approval of a limited maintenance plan (LMP) as a revision to the West Virginia State Implementation (SIP). In this action, EPA is approving the State's request to redesignate the area from nonattainment to attainment, as well as approving the LMP for the Weirton Area.

EPA is proposing to revoke certain tolerances for the fungicide carboxin, the insecticide dipropyl isocinchomeronate, and the fungicide/animal repellent oil of lemon (oil of lemongrass) and oil of orange. Also, EPA is proposing to modify certain tolerances for the herbicide bentazon and the fungicide carboxin. In addition, EPA is proposing to establish new tolerances for the herbicide bentazon. The regulatory actions proposed in this document are part of the Agency's reregistration program under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and the tolerance reassessment requirements of the Federal Food, Drug, and Cosmetic Act (FFDCA) section 408(q), as amended by the Food Quality Protection Act (FQPA) of 1996. By law, EPA is required by August 2006 to reassess the tolerances that were in existence on August 2, 1996. No tolerance reassessments will be counted at the time of a final rule because tolerances in existence on August 2, 1996 that are associated with actions proposed herein were previously counted as reassessed at the time of the completed Reregistration Eligibility Decision (RED), Report of Food Quality Protection Act (FQPA) Tolerance Reassessment Progress and Risk Management Decision (TRED), or Federal Register.

This notice announces the initial filing of a pesticide petition proposing the establishment of regulations for residues of sulfosulfuron in 1-(4,6-dimethoxypyrimidin-2-yl)-3-[(2-ethane-sulfonyl- imidazo[1,2-a]pyridine-3-yl)sulfonyl]urea, and its metabolites converted to 2-(ethylsulfonyl)imidazo[1,2-a]pyridine and calculated as sulfosulfuron or on grass (forage and hay), milk, and fat, meat, and meat byproducts of cattle, goat, horse, and sheep.

This notice announces the initial filing of a pesticide petition proposing the establishment of regulations for residues of tribenuron methyl (methyl 2-[[[[(4-methoxy-6-methyl-1,3,5 -triazin-2- yl)methylamino] carbonyl]amino]sulfonyl] benzoate) in or on field corn and grain sorghum (forage, grain, and stover), rice (grain and straw), soybean seed, and sunflowers.

This notice announces the initial filing of a pesticide petition proposing the establishment of regulations for residues of in rimsulfuron (N-((4,6-dimethoxypyrimidin-2-yl)aminocarbonyl)-3- (ethylsulfonyl)-2-pyridinesulfonamide) in or on almond hulls, citrus/ pome/stone fruit crop groups, grapes, pistachios, and tree nuts crop group.

On November 10, 2003, EPA promulgated national emission standards for hazardous air pollutants for miscellaneous organic chemical manufacturing. Several petitions for judicial review of the final rule were filed in the United States Court of Appeals for the District of Columbia Circuit. Petitioners expressed concern with various requirements in the final rule, including applicability of specific operations and processes, the leak detection and repair requirements for connectors, criteria to define affected wastewater streams requiring control, control requirements for wastewater streams that contain only soluble hazardous air pollutants, the definition of ``process condensers,'' and recordkeeping requirements for Group 2 batch process vents. In this action, EPA amends the final rule to address these issues and to correct inconsistencies that have been discovered during the review process.
