II. Background

A. What Action is the Agency Taking?

Under section 4 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), EPA is reevaluating existing pesticides to ensure that they meet current scientific and regulatory standards. EPA has completed a Reregistration Eligibility Decision (RED) for the pesticides, Phytophthora palmivora MWV and methyl salicylate under section 4(g)(2)(A) of FIFRA.

Below is a summary of each case:

1. Phytophthora palmivora. MWV- Case 4105 (PC Code 111301). Phytophthora palmivora MWV is a fungus that controls milk weed vine in citrus groves by attacking their roots. It is a plant pathogen that is very specific for this target plant pest and occurs naturally in Florida in the counties for which it is labeled. The active ingredient, P. palmivora, was registered in 1981 by Abbott Laboratories but was transferred on April 29, 2000, to Valent BioSciences Corporation who still holds the registration. Valent's label for Devine Biological Herbicide indicates that the product is for use on citrus groves in Florida only and “do not use Start Printed Page 36791in Clay, Gulf, Liberty, or Gadsden counties.” It is to be applied approximately once every two years. It is considered in Toxicity Category IV based on acute toxicology tests in mammalian systems as described in the RED. No hypersensitivity incidents have been reported in association with the use of this pesticide. This fungal active ingredient is not expected to harm human adults, infants and children via dietary, non-dietary, aggregate, occupational, residential and cumulative exposures. The exemption from tolerance was reassessed and the database complies with the Food Quality Protection Act of 1996. The pesticide is not to be used in counties where susceptible endangered species are found. No harm is expected to human health and the environment including birds, beneficial insects, aquatic and other non-target terrestrial organisms, and wildlife. There is a “not likely to adversely affect” (NLAA) endangered species determination when the labeling excludes applications in counties where endangered plants may be found.

2. Methyl salicylate. Case 4080 (PC Code 076601). Methyl salicylate is a biochemical insect and animal repellant. Methyl salicylate was first registered in 1972 for use as an animal repellent in impregnated twist tabs hung on plants to repel dogs and cats from flower gardens. In 1996, the Agency registered methyl salicylate as an insect repellent to be used as a constituent of food and feed packaging material to repel insects in stored commodities (e.g. Indian meal moths). This registration is considered to be a “food use”, since it entails use in stored food commodities which necessitated the establishment of an exemption from the requirements of a tolerance (Refer to 40 CFR 180.1189). The active ingredient methyl salicylate is considered to be a low toxicity biochemical (toxicity categories III and IV) as described in the RED on the basis of toxicological mammalian tests for acute oral, dermal effects and primary eye and skin irritations. No reported incidents of hypersensitivity have been reported to the Agency. In fact, methyl salicylate has a long history of use in consumer products as a counterirritant and as an analgesic in the treatment and temporary management of aching and painful muscles and joints. Methyl salicylate is also used in suntan lotions as an UV-absorber, and in perfumery as a modifier of blossom fragrances. Because of its use patterns, as twist tabs in flower gardens and a constituent of food packaging, methyl salicylate is not expected to harm aquatic or terrestrial non-target birds, fish, beneficial insects or plants or the environment. The data base supporting the RED complies with the Food Quality Protection Act of 1996. No harm is expected to human adults, infants, and children from dietary, non-dietary, aggregate, residential and occupational and cumulative exposure when this biochemical pesticide is used as labeled.

EPA has determined that the data base to support reregistration is substantially complete and that products containing Phytophthora palmivora MWV and methyl salicylate are eligible for reregistration depending on their specific uses, provided the risks are mitigated either in the manner described in the RED or by another means that achieves equivalent risk reduction. Upon submission of any required product specific data under section 4(g)(2)(B) and any necessary changes to the registration and labeling (either to address concerns identified in the RED or as a result of product specific data), EPA will make a final reregistration decision under section 4(g)(2)(C) for products containing Phytophthora palmivora MWV and methyl salicylate.

EPA must review tolerances and tolerance exemptions that were in effect when the Food Quality Protection Act (FQPA) was enacted in August 1996, to ensure that these existing pesticide residue limits for food and feed commodities meet the safety standard established by the new law. Tolerances are considered reassessed once the safety finding has been made or a revocation occurs. EPA has reviewed and made the requisite safety finding for the Phytophthora palmivora MWV and methyl salicylate exemptions from tolerances included in this notice.

Although the Phytophthora palmivora MWV and Methyl salicylate REDs were signed on March 1, 2006, and September 22, 2005, respectively, certain components of the document, which did not affect the final regulatory decision, were undergoing final editing at that time. These components, including the list of additional generic data requirements, summary of labeling changes, appendices, and other relevant information, have been added to the Phytophthora palmivora MWV and methyl salicylate RED document. In addition, subsequent to signature, EPA identified several minor errors and ambiguities in the document. Therefore, for the sake of accuracy, the Agency also has included the appropriate error corrections, amendments, and clarifications. None of these additions or changes alter the conclusions documented in the March 1, 2006, Phytophthora palmivora MWV and September 22, 2005, methyl salicylate RED. All of these changes are described in detail in an errata memorandum which is included in the public docket for Phytophthora palmivora MWV and methyl salicylate

EPA is applying the principles of public participation to all pesticides undergoing reregistration and tolerance reassessment. The Agency's Pesticide Tolerance Reassessment and Reregistration; Public Participation Process, published in the Federal Register on May 14, 2004, (69 FR 26819) (FRL-7357-9) explains that in conducting these programs, EPA is tailoring its public participation process to be commensurate with the level of risk, extent of use, complexity of issues, and degree of public concern associated with each pesticide. Due to its uses, risks, and other factors, Phytophthora palmivora MWV and methyl salicylate was reviewed through the full 6-Phase or modified 4-Phase process. Through this process, EPA worked extensively with stakeholders and the public to reach the regulatory decisions for Phytophthora palmivora MWV and methyl salicylate.

The reregistration program is being conducted under Congressionally mandated time frames, and EPA recognizes the need both to make timely decisions and to involve the public. The Agency is issuing the Phytophthora palmivora MWV and methyl salicylate RED for public comment. This comment period is intended to provide an additional opportunity for public input and a mechanism for initiating any necessary amendments to the RED. All comments should be submitted using the methods in ADDRESSES, and must be received by EPA on or before the closing date. These comments will become part of the Agency Docket for Phytophthora palmivora MWV and methyl salicylate. Comments received after the close of the comment period will be marked “late.” EPA is not required to consider these late comments.

The Agency will carefully consider all comments received by the closing date and will provide a Response to Comments Memorandum in the Docket and If any comment significantly affects the document, EPA also will publish an amendment to the RED in the Federal Register. In the absence of substantive comments requiring changes, the Phytophthora palmivora MWV and methyl salicylate RED will be implemented as it is now presented.Start Printed Page 36792

B. What is the Agency's Authority for Taking this Action?

Section 4(g)(2) of FIFRA as amended directs that, after submission of all data concerning a pesticide active ingredient, the Administrator shall determine whether pesticides containing such active ingredient are eligible for reregistration, before calling in product specific data on individual end-use products and either reregistering products or taking other “appropriate regulatory action.”

Section 408(q) of the Federal Food, Drug, and Cosmetic Act (FFDCA), 21 U.S.C. 346a(q), requires EPA to review tolerances and exemptions for pesticide residues in effect as of August 2, 1996, to determine whether the tolerance or exemption meets the requirements of section 408(b)(2) or (c)(2) of FFDCA. This Agency review is to be completed by August 3, 2006. EPA has reviewed and made the requisite safety finding for the exemptions from tolerances for the following pesticides: Phytophthora palmivora MWV and the biochemical pesticide methyl salicylate included in this notice. The exemptions from tolerances for these two biopesticides comply with the requirements of FQPA.
