May 2, 2007 EPA-HQ-OPP-2007-0036

Proposed Tolerance Action. EPA is proposing to modify certain tolerances for the herbicide oxyfluorfen and is proposing to establish new tolerances. The regulatory actions proposed in this document are in 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). EPA has issued a post-FQPA REDs for oxyfluorfen. Comments must be received on or before July 2, 2007.

Based on available data that showed residues of oxyfluorfen as high as 0.03 ppm in or on mint hay, EPA determined that the tolerance on mint hay (peppermint and spearmint) should be decreased from 0.1 to 0.05 ppm. Therefore, the Agency is proposing in 40 CFR 180.381(a) to revise the commodity terminology for mint hay into separate tolerances on peppermint, tops and spearmint, tops and decrease each tolerance to 0.05 ppm.

Based on available exaggerated (5x to 7x MTDB) cattle feeding data that showed residues of oxyfluorfen as high as < 0.003 ppm in milk, 0.007 ppm in fat, < 0.003 ppm in meat, < 0.003 ppm in kidney, and < 0.003 ppm in liver, EPA expected residues below the LOQ (0.01 ppm) in milk, fat, meat, and meat byproducts at the 1x MTDB for cattle. The Agency determined that the tolerances on milk and the fat, meat and meat byproducts of cattle, goats, hogs, horses, and sheep should be set at the LOQ and decreased from 0.05 to 0.01 ppm. Therefore, EPA is proposing in 40 CFR 180.381(a) to decrease the tolerances on milk; cattle, fat; cattle, meat; cattle, meat byproducts; goat, fat; goat, meat; goat, meat byproducts; hog, fat; hog, meat; hog, meat byproducts; horse, fat; horse, meat; horse, meat byproducts; sheep, fat; sheep, meat; and sheep, meat byproducts to 0.01 ppm.

Based on available exaggerated (2.0x MTDB) poultry feeding data that showed residues of oxyfluorfen as high as 0.024 ppm in eggs, 0.163 ppm in fat, 0.004 ppm in meat, and 0.006 ppm in liver, EPA expected residues of 0.012 ppm in egg, 0.082 ppm in fat, 0.002 ppm in meat, and 0.003 ppm in liver at the 1x MTDB for poultry. The Agency determined that the tolerances should be decreased on egg from 0.05 to 0.03 ppm, meat and meat byproducts from 0.05 to 0.01 ppm, and increased on fat from 0.05 to 0.2 ppm. Therefore, EPA is proposing in 40 CFR 180.381(a) to decrease the tolerances on egg to 0.03 ppm, poultry, meat to 0.01 ppm, poultry, meat byproducts to 0.01 ppm, and increase the tolerance on poultry, fat to 0.2 ppm. The Agency determined that the increased tolerance is safe; i.e., there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue. Based on available data that showed oxyfluorfen residues from use of oxyfluorfen on grass grown for seed in Oregon and Washington were not detectable (< 0.03 ppm) in or on grass forage, hay, and seed screenings, EPA determined that the reassessed animal commodity tolerances are adequate to cover any residue contribution from regional registration uses of oxyfluorfen on grasses grown for seed and tolerances should be established on grass forage, hay, and seed screenings at 0.05 ppm. Therefore, the Agency is proposing to establish tolerances in 40 CFR 180.381(c) on grass, forage; grass, hay; and grass, seed screenings; each at 0.05 ppm.

In addition, EPA is proposing to revise commodity terminology in 40 CFR 180.381 to conform to current Agency practice as follows:

``banana (including plantain)'' to ``banana''
``coffee, bean'' to ``coffee, bean, green;'' `
`corn, grain'' to ``corn, field, grain'' and ``corn, pop, grain;''
``onion, dry bulb'' to ``onion, bulb;''
``taro, corm and leaves'' to ``taro, corm'' and ``taro, leaves.

Moreover, it should be noted that use of oxyfluorfen on plantains is covered by the existing tolerance at 0.05 ppm for banana under 40 CFR 180.1(g), and there is no need to establish a separate tolerance on plantains at 0.05 ppm. Also, because use of oxyfluorfen on garlic is covered by the existing tolerance at 0.05 ppm for onion bulb under 40 CFR 180.1(g), there is no need to establish a separate tolerance on garlic at 0.05 ppm as had been recommended in the RED.

Availability of Court Orders in Washington Toxics Coalition v. EPA Litigation. The Order (with some exceptions) enjoins, vacates and sets aside EPA's authorization of certain pesticides' uses within 20 yards for ground applications and 100 yards for aerial applications, adjacent to salmon supporting waters in California, Oregon and Washington, effectively establishing buffer zones around those waters. This order applies to 38 pesticides, including the fluoridated
Diflubenzuron, Oxyfluorfen, Trifluralin.
The Court's January 22 Order, which carries an effective date of February 5, 2004, and other related materials, including the Court's previous Orders, are available at:

US EPA's Pesticide Reregistration Performance Measures and Goals.
In EPA's Fiscal Year 2002 - Reregistration/Risk Management Decisions Completed (Reregistration Eligibility Decision - RED). Oxyfluorfen was one of 7 REDs completed by EPA in FY 2002.

1. The number of registered products containing a pesticide active ingredient can change over time. The number of products that appears in the RED document (counted when the RED is signed) may be different than the number of products that EPA is tracking for product reregistration (counted later, when the RED is issued). This table reflects the final number of products associated with each RED, as they are being tracked for product reregistration.
2. This column shows the number of product chemistry studies that are required for each product covered by the RED.
3. In an effort to reduce the time, resources, and number of animals needed to fulfill acute toxicity data requirements, EPA ``batches'' products that can be considered similar from an acute toxicity standpoint. For example, one batch could contain five products. In this instance, if six acute toxicology studies usually were required per product, only six studies (rather than 30 studies) would be required for the entire batch. Factors considered in the sorting process include each product's active and inert ingredients (e.g., identity, percent composition, and biological activity), type of formulation (e.g., emulsifiable concentrate, aerosol, wettable powder, granular), and labeling (e.g., signal word, use classification, precautionary labeling). The Agency does not describe batched products as ``substantially similar,'' because all products within a batch may not be considered chemically similar or have identical use patterns.
Oct 30, 2002 OPP-2002-0255 Availability of Reregistration Eligibility Decision (RED) Document for Comment.
EPA's RED document is available at: http://www.epa.gov/oppsrrd1/REDs/oxyfluorfen_red.pdf - one excerpt: "Cancer risk to workers is of greater concern than non-cancer risk. Occupational cancer risks, when calculated without personal protective equipment or engineering controls, can range up to 1 x 10 -3 . With the protection specified on several current labels, most scenarios result in cancer risks in the 10 -5 range."

May 17, 2002 OPP-2002-0037 Revocation of Expired Time Limited Tolerances. FINAL RULE. The time-limited tolerance for strawberries is being removed from 40 CFR 180.381 because it expired on April 15, 2001.
April 30, 2002 OPP-2002-0056 Proposed Consent Decree involving pesticides and the Endangered Species Act. This proposed consent decree, if entered by the Court, would resolve a lawsuit brought against EPA under the Endangered Species Act (ESA), by Californians for Alternatives to Toxics (CATs), the Environmental Protection Information Center, Inc., and the Humboldt Watershed Council (jointly, Plaintiffs). The proposed Consent Decree sets a series of deadlines for initiating a number of consultations with the FWS and the NMFS relative to certain pesticide uses and their potential effects on certain plants and fish, including: Consultation on the effects of certain pesticide uses of registered pesticide products containing the active ingredients glyphosate, hexazinone, and oxyfluorfen on six species of listed salmon and steelhead and their designated critical habitat (collectively referred to as ``salmonids'').

Dec14, 1994 NA

ROHM & HAAS - Request to Revoke Food Additive Regulations on cottonseed oil, mint oil, and soybean oil. This document announces the receipt of, and solicits comments on, a petition proposing the revocation of the section 409 food additive regulations (FAR) established under the Federal Food, Drug and Cosmetic Act for the herbicide oxyfluorfen and its metabolites containing the diphenyl ether linkage (hereinafter oxyfluorfen). This exemption in section 402(a)(2) is commonly referred to as the ``flow-through'' provision because it allows the section 408 raw food tolerance to flow through to processed food. Thus, a section 409 FAR is only necessary to prevent foods from being deemed adulterated when despite the use of good manufacturing practices the concentration of the pesticide residue in a processed food is greater than the tolerance prescribed for the raw agricultural commodity, or if the processed food itself is treated or comes into contact with a pesticide.

Jan 12, 1994 OPPTS-400082 EPA's proposal to add 41 fluorine and organofluorine chemicals to the Toxics Release Inventory (TRI). See excerpt in box above. Also available at http://www.epa.gov/tri/frnotices/59fr1788.htm
1993 NA

ROHM & HAAS - 1993 Pesticide Tolerance Petition for residues in or on PEANUTS: meat at 0.05 ppm; vine at 0.05 ppm; hay at 0.05 ppm; hulls at 0.10 ppm. The Fed. Reg. does not have online access for 1993. This petition was summarized by USDA.
