Environmental Protection Agency September 26, 2007 – Federal Register Recent Federal Regulation Documents

This regulation revises and separates the tolerances for alachlor in Sec. 180.249 into paragraphs (a) through (d). This regulation also establishes several new tolerances under paragraph (a). It further establishes several new tolerances under paragraph (d). Details of these changes are outlined in Unit II. of this document. Monsanto Company requested these changes as submitted by petitions to EPA pursuant to the Federal Food, Drug, and Cosmetic Act (FFDCA).

EPA is proposing to approve a revision to the Arkansas State Implementation Plan (SIP) submitted on August 10, 2007, enacted at Regulation 19Arkansas Plan of Implementation for Air Pollution Control; Chapter 14, Sections 19.1401-19.1404; and Chapter 15, Section 19.1501. This revision addresses the requirements of EPA's Clean Air Interstate Rule (CAIR) Nitrogen Oxides (NOX) Ozone Season Trading Program, promulgated on May 12, 2005 and subsequently revised on April 28 and December 13, 2006. EPA is proposing to determine that the SIP revision fully implements the CAIR NOX ozone season requirements for Arkansas. Therefore, as a consequence of the SIP approval, EPA will also withdraw the CAIR Federal Implementation Plan (CAIR FIP) concerning NOX emissions for Arkansas. The CAIR FIPs for all States in the CAIR region were promulgated on April 28, 2006 and subsequently revised on December 13, 2006. The intended effect of this action is to reduce NOX emissions from the State of Arkansas that are contributing to nonattainment of the 8-hour ozone National Ambient Air Quality Standard (NAAQS or standard) in downwind states. This action is being taken under section 110 of the Federal Clean Air Act (the Act or CAA).

EPA is revoking certain tolerances for the insecticide oxydemeton-methyl. Also, EPA is modifying certain tolerances for the insecticides oxydemeton-methyl, profenofos, and trichlorfon. In addition, EPA is establishing new tolerances for the insecticides oxydemeton-methyl and profenofos. EPA is not taking action on tolerances for methamidophos at this time. The regulatory actions finalized in this document are follow-up to the Agency's reregistration program under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), and tolerance reassessment program under the Federal Food, Drug, and Cosmetic Act (FFDCA) section 408(q).

This notice sets forth EPA's Proposed Determination to Terminate Special Review for the pesticide Dichlorvos (DDVP). On February 24, 1988, the Agency published a Notice of Special Review (PD 1) of pesticide products containing DDVP based on concerns for cancer, cholinesterase inhibition, and liver effects. (53 FR 5542). On September 28, 1995, the Agency published a Notice of Preliminary Determination to Cancel Certain Registrations and a Draft Notice of Intent to Cancel (PD 2/3). (60 FR 50337). In the 1995 PD 2/3, the Agency determined that exposure to dichlorvos from the registered uses posed carcinogenic risks of concern as well as risks of concern for cholinesterase inhibition. However, with respect to liver effects, the Agency determined that this endpoint was no longer of regulatory concern. Since the initiation of Special Review and publication of the PD 2/3, additional data have become available. Based in part on these data, the Agency has changed its assessment of some of the risks associated with DDVP, and modified the terms and conditions of DDVP registrations, accordingly. Moreover, during the recently-concluded reregistration process for DDVP, EPA conducted an intensive and public review of whether DDVP registrations meet the FIFRA standard for registration, culminating in the Agency's 2006 Interim Reregistration Eligibility Decision (IRED) for DDVP. Through the reregistration processes the Agency resolved remaining concerns regarding cancer and cholinesterase effects. Accordingly, EPA has revised its assessment of DDVP since the time when the PD 1 and the PD 2/3 were published. Based on the IRED, requested label amendments, and the voluntary cancellation of uses by the registrant pursuant to section 6(f) of FIFRA, EPA has determined that the risks that were the basis of the Special Review are no longer of concern and, therefore, the Agency is proposing to terminate the Special Review of DDVP. To the extent that the Agency further revises its assessment of DDVP, it will do so outside of the Special Review context.

This regulation establishes tolerances for combined residues of pyraclostrobin and its desmethoxy metabolite in or on berry, group 13; cotton, undelinted seed; and cotton, gin byproducts. BASF Corporation requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA).

EPA is approving a revision to the Missouri State Implementation Plan (SIP) that will fulfill the condition of a previously-published approval (July 11, 2006). The revision amends the Construction Permits By Rule and requires a preconstruction review period before sources may begin construction.

This notice announces the availability of EPA's Reregistration Eligibility Decision (RED) for the allethrin series of pesticides (bioallethrin, esbiol, esbiothrin, and pynamin forte). The Agency's risk assessments and other related documents also are available in the allethrins docket. The allethrins are synthetic pyrethroids used as insecticides on both indoor (residential and commercial) and outdoor (residential, commercial, and recreational) use sites. EPA has reviewed the allethrins through the public participation process that the Agency uses to involve the public in developing pesticide reregistration and tolerance reassessment decisions. Through these programs, EPA is ensuring that all pesticides meet current health and safety standards.
