Environmental Protection Agency August 1, 2007 – Federal Register Recent Federal Regulation Documents

EPA is revoking certain tolerances for the herbicides bromoxynil, diclofop-methyl, and paraquat; the fungicide etridiazole (terrazole); the miticides dicofol and propargite; and the plant growth regulator and herbicide diquat. Also, EPA is removing duplicate tolerances for the herbicides bromoxynil, paraquat, and picloram; the fumigant phosphine; the miticide dicofol; and the insecticides fenbutatin-oxide and hydramethylnon. In addition, EPA is modifying certain tolerances for the insecticide hydramethylnon; the herbicides bromoxynil, paraquat, and triclopyr; the fungicides etridiazole, folpet, and triphenyltin hydroxide (TPTH); the miticides dicofol and propargite; and the plant growth regulator and herbicide diquat. Moreover, EPA is establishing new tolerances for the herbicides bromoxynil, paraquat, and picloram; the fungicides etridiazole, folpet, and TPTH; the miticides dicofol and propargite; the insecticide fenbutatin-oxide; and the plant growth regulator and herbicide diquat. The regulatory actions in this document are follow-up to the Agency's reregistration program under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and reassessment program under the Federal Food, Drug, and Cosmetic Act (FFDCA) section 408(q).

EPA is seeking public comment on the document entitled Statistical Basis of the NAFTA Method for Calculating Pesticide Maximum Residue Limits from Field Trial Data available at https://www.pmra- arla.gc.ca/english/pdf/nafta/docs/naftamrls-e.pdf. Although Canada's Management Regulatory Agency (PMRA) is also accepting comments, EPA and PMRA will be jointly responding to comments submitted to either agency. The document was prepared by the NAFTA MRL Harmonization Working Group (a group comprised of United States and Canadian governments, created to develop a coordinated pesticides regulatory framework among North American Free Trade Agreement (NAFTA) partners). The document provides additional technical and explanatory material for a standard operating procedure (SOP) previously released by Canada's PMRA for public comment in September 2005. The document currently open for public comment supports the September 2005 draft SOP that is intended for use by residue chemistry reviewers in the United States and Canada to ensure that the same or similar residue chemistry data sets will result in the same or similar recommendation for maximum residue limit (MRL) levels for pesticide residues on food and feed commodities by each agency. The goal for this method is to minimize trade barriers of pesticide treated commodities between the United States and Canada.

EPA proposes to approve the State Implementation Plan (SIP) revision submitted by the state of Iowa for maintenance of the sulfur dioxide National Ambient Air Quality Standard in Muscatine, Iowa.

EPA is approving a State Implementation Plan (SIP) revision submitted by the State of Maryland. This revision consists of clarifications to the exception provisions of the Maryland visible regulations.

EPA has established registration review dockets for the following pesticides: Fenoxycarb (case number 7401) and urea sulfate (case number 7213). With this document, EPA is opening the public comment period for these registration reviews. 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, the pesticide can perform its intended function without unreasonable adverse effects on human health or the environment. Registration review dockets contain information that will assist the public in understanding the types of information and issues that the Agency may consider during the course of registration reviews. 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.

This notice announces the initial filing of pesticide petitions proposing the establishment or modification of regulations for residues of pesticide chemicals in or on various commodities.

This notice announces receipt of an application 67979-EUP-7 from Syngenta Seeds, Inc. requesting an experimental use permit (EUP) for the plant-incorporated protectants COT102 Bacillus thuringiensis Vip3Aa19 protein and the genetic material (plasmid vector pCOT1) necessary for its production in cotton and COT67B Bacillus thuringiensis Cry1Ab protein and the genetic material (plasmid vector pNOV4641) necessary for its production in cotton. The Agency has determined that the application may be of regional and national significance. Therefore, in accordance with 40 CFR 172.11(a), the Agency is soliciting comments on this application.

This notice announces the initial filing of pesticide petitions proposing the establishment or modification of regulations for residues of pesticide chemicals in or on various commodities.

EPA is announcing its intent to partially delete 61 source area sites on the Otis Air National Guard Base/Camp Edwards Superfund Site from the National Priorities List (NPL) and requests public comment on this action. A source area site is defined by: soil; structures, if present; and does not include any contaminated groundwater plume that may be below the site. Otis Air National Guard Base/Camp Edwards is a Federal Facility Superfund Site known locally as the Massachusetts Military Reservation (MMR), so this notice will use MMR as the abbreviation to describe the entire Superfund Site. The United States Air Force is the lead agency at the MMR Superfund Site. EPA bases its proposal to partially delete the 61 source area sites from the MMR Superfund Site on the determination of EPA and the Commonwealth of Massachusetts, through the Massachusetts Department of Environmental Protection (MassDEP), that all appropriate response actions under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) have been implemented to protect human health, welfare, and the environment and that no further response actions by responsible parties, at these 61 sites, are appropriate. Based on all investigations completed to date, there are 80 source area sites at MMR. Upon conclusion of this process, there would be 19 source area sites remaining. This partial deletion pertains to only the surface area of sites investigated (and in some cases cleaned-up) for soil contamination, and does not pertain to any of the 12 groundwater plumes associated with MMR Superfund Site. All other sites (including all contaminated groundwater plumes on the Site) not included in this notice will remain on the NPL. In the northern half of the MMR, there are source area sites and groundwater plumes associated with an investigation and cleanup program known as the Impact Area Groundwater Study Program which is being conducted under the authority of Safe Drinking Water Act Administrative Orders. These sites and groundwater plumes are not the subject of this partial deletion proposal. The NPL, promulgated pursuant to section 105 of CERCLA, as amended, is Appendix B of 40 CFR part 300, which is the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). This partial deletion of the Otis Air National Guard Base/Camp Edwards Superfund Site is proposed in accordance with 40 CFR 300.425(e) and the Notice of Policy Change: Partial Deletion of Sites Listed on the National Priorities List (60 FR 55466). This action is being proposed by EPA with the concurrence of the Commonwealth of Massachusetts, through the MassDEP, because EPA has determined that all appropriate response actions under CERCLA have been completed and, therefore, further remedial action pursuant to CERCLA is not appropriate.

EPA is taking direct final action to approve revisions to the Sacramento Metropolitan Air Quality Management District (SMAQMD) and San Joaquin Valley Air Pollution Control District (SJVAPCD) portions of the California State Implementation Plan (SIP). These revisions concern oxides of nitrogen (NOX) emissions from boilers, process heaters, steam generators, and glass melting furnaces. We are approving local rules that regulate these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).

EPA is finalizing a limited approval and limited disapproval of revisions to the Pinal County Air Quality Control District (PCAQCD) portion of the Arizona State Implementation Plan (SIP). This action was proposed in the Federal Register on October 17, 2006 and concerns particulate matter (PM-10) emissions from fugitive dust. Under authority of the Clean Air Act as amended in 1990 (CAA or the Act), this action simultaneously approves local rules that regulate these emission sources and directs Arizona to correct rule deficiencies.
