Environmental Protection Agency August 18, 2010 – Federal Register Recent Federal Regulation Documents

Notice is hereby given that the Environmental Protection Agency (EPA) has designated, in accordance with 40 CFR Part 53, two new equivalent methods for measuring concentrations of PM10 and sulfur dioxide (SO2) in the ambient air.

EPA is announcing an extension of the public comment period for two related draft documents: (1) ``The Effects of Mountaintop Mines and Valley Fills on Aquatic Ecosystems of the Central Appalachian Coalfields'' (EPA/600/R-09/138A) and (2) ``A Field-based Aquatic Life Benchmark for Conductivity in Central Appalachian Streams'' (EPA/600/R- 10/023A). We are specifically extending the comment period on these two documents to give the public additional time to evaluate the data used to derive a benchmark for conductivity. The original Federal Register notice announcing the public comment period was published on April 12, 2010 (75 FR 18499). By following the link below, reviewers may download the initial data and EPA's derivative data sets that were used to calculate the conductivity benchmark. These reports were developed by the National Center for Environmental Assessment (NCEA) within EPA's Office of Research and Development as part of a set of actions taken by EPA to further clarify and strengthen environmental permitting requirements for Appalachian mountaintop removal and other surface coal mining projects, in coordination with Federal and State regulatory agencies (https://www.epa.gov/owow/wetlands/guidance/mining.html).

EPA issued a notice in the Federal Register of January 13, 2010, concerning the Agency's receipt of an initial filing of a pesticide petition. This document is being issued to correct omissions and to also reopen the comment period for an additional 30 days.

In accordance with section 6(f)(1) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended, EPA is issuing a notice of receipt of request by the registrant to voluntarily cancel a pesticide registration.

EPA has granted emergency exemptions under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) for use of pesticides as listed in this notice. The exemptions were granted during the period October 1, 2009 to June 30, 2010 to control unforeseen pest outbreaks.

This notice announces receipt of applications to register new uses for pesticide products containing currently registered active ingredients, pursuant to the provisions of section 3(c) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended. EPA is publishing this Notice of such applications, pursuant to section 3(c)(4) of FIFRA.

This regulation establishes an exemption from the requirement of a tolerance for residues of diethylene glycol (DEG) (CAS No. 111-46- 6) when used as an inert ingredient as a solvent, stabilizer and/or antifreeze within pesticide formulations without limitation, under 40 CFR 180.920, for use on growing crops and raw agricultural commodities pre-harvest Huntsman, Dow AgroSciences L.L.C., Nufarm Americas Inc., BASF, Stepan Company, Loveland Products Inc., and Rhodia Inc. submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of DEG.

This regulation establishes an exemption from the requirement of a tolerance for residues of 2-(2'-hydroxy-3', 5'-di-tert-amylphenyl) benzotriazole (CAS Reg. No. 25973-55-1) and Phenol, 2-(2H- benzotriazole-2-yl)-6-dodecyl-4-methyl; (CAS Reg. No. 23328-53-2) when used as a ultraviolet (UV) stabilizer at a maximum concentration of 0.6% in insecticide formulations applied pre-harvest to adzuki beans, canola, chickpeas, cotton, faba beans, field peas, lentils, linola, linseed, lucerne, lupins, mung beans, navy beans, pigeon peas, safflower, sunflower, and vetch under 40 CFR 180.920. Ag-Chem Consulting on behalf of Caltex Inc. submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of 2-(2'-hydroxy-3', 5'-di-tert-amylphenyl) benzotriazole and Phenol, 2-(2H-benzotriazole-2- yl)-6-dodecyl-4-methyl.

The Environmental Protection Agency Region VIII is making a final determination to approve an alternative final cover for the Lake County landfill, a municipal solid waste landfill (MSWLF) owned and operated by Lake County, Montana on the Confederated Salish and Kootenai Tribes' Flathead Reservation in Montana. EPA is promulgating a site-specific rule proposed on February 10, 2010, that approves an alternative final cover for the Lake County, Montana landfill.

This notice announces the availability of EPA's proposed registration review decisions for the pesticides propionic acid and salts, and urea sulfate and opens a public comment period on the proposed decisions. Registration review is EPA's periodic review of pesticide registrations to ensure that each pesticide continues to satisfy the statutory standard for registration, that is, that the pesticide can perform its intended function without unreasonable adverse effects on human health or the environment. Through this program, EPA is ensuring that each pesticide's registration is based on current scientific and other knowledge, including its effects on human health and the environment.

There will be a 4-day meeting of the Federal Insecticide, Fungicide, and Rodenticide Act Scientific Advisory Panel (FIFRA SAP) to consider and review the Chlorpyrifos Physiologically Based Pharmacokinetic/Pharmacodynamic (PBPK/PD) Model linked to the Cumulative and Aggregate Risk Evaluation System (CARES).
