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 pesticide metaldehyde under section 4(g)(2)(A) of FIFRA. Metaldehyde is a molluscicide used to control snails and slugs on a wide variety of sites, including turf, ornamentals, berries, citrus, and vegetables. EPA has determined that the data base to support reregistration is substantially complete. The technical registrant of metaldehyde, Lonza, elected not to support many uses through the development of residue and other data. Of the uses Lonza is supporting, turf and dichondra lawns are not eligible for reregistration, mainly based on the risks these residential uses pose to domestic animals, which may be Start Printed Page 45553poisoned by ingesting metaldehyde pellets intended as snail and slug baits. The uses of metaldehyde that are eligible for reregistration are: Ornamentals, citrus, cole crops, several leafy greens (including lettuce and spinach), tomato, strawberry, berries (including blackberry, blueberry, currant, elderberry, gooseberry, and raspberries), artichoke, and grass grown for seed. To mitigate the risks associated with the eligible uses of metaldehyde, the Agency is requiring that the registrants implement a number of measures aimed at reducing exposures to domestic animals and wildlife, mainly through reduced numbers of applications and reduced application rates, and product labeling and reformulation. In addition, the Agency is requiring that the registrants undertake a comprehensive incident monitoring program, data from which will be used by the Agency to determine whether these risk mitigation measures adequately reduce numbers and severity of poisoning incidents for domestic animals. Upon submission of any required generic and product-specific data pursuant to the RED, and any necessary changes to metaldehyde registrations and product labeling (either to address concerns identified in the RED or resulting from the use of product-specific data), EPA will make a final reregistration decision under section 4(g)(2)(C) for products containing metaldehyde.

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 sole existing metaldehyde tolerance.

Although the metaldehyde RED was signed on July 27, 2006, certain components of the document, which did not affect the final regulatory decision, are undergoing final editing at this time. These components, including the list of additional generic data requirements, summary of labeling changes, appendices, and other relevant information, will be added to the metaldehyde RED when they are complete. None of these additions will alter the conclusions documented in the July 27, 2006 metaldehyde RED.

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, metaldehyde was reviewed through the modified 4-Phase process. Through this process, EPA worked extensively with stakeholders and the public to reach the regulatory decisions for metaldehyde.

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 metaldehyde 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 metaldehyde. Comments received after the close of the comment period will be marked “late.” EPA is not required to consider these late comments.-

In particular, during the 60-day comment period following the publication of this Notice, the Agency is soliciting input on several of the mitigation measures required by the RED. -

The Agency is specifically seeking public comment on how the directions on home and garden product labels to exclude children and domestic animals from treated areas may be enhanced. As an example, the RED requires that these product labels include a graphic representing the prohibition for allowing children and domestic animals access to treated areas (e.g., the words “Children and Pets” within a red circle with a red bar running diagonally through the circle). The formulators of metaldehyde products have commented that they believe a “Children and Pets” graphic of this nature could be misleading to consumers. Comments on this feature in particular are requested.

In addition, the Agency seeks public comment on a requirement that all metaldehyde granular products be formulated with a bright blue pigment, which anecdotal evidence suggests may deter ingestion by animals. Some registrants have expressed concern that the blue color could attract children who might mistake the granules for candy. The Agency is soliciting input on this issue and data on the potential effect of the blue color on ingestion of such material by animals. The registrants are also concerned that the blue color in granules could transfer to produce or the containers in which harvested produce is transported, reducing the marketability of the produce. The Agency believes that the soil-applied baits should have little likelihood of transferring color to plants, but is seeking public comment on experience with the pigmented formulations in agricultural sites, where they are already used.

The Agency is also seeking input on a prohibition of use for metaldehyde in strawberries grown as annuals. The annual growth pattern is typically associated with lower populations of slugs which may do little economic damage to the fruits. The Agency seeks information to be able to confirm or refute that the use of metaldehyde on strawberries grown as annuals is not necessary.-

The Agency will carefully consider all comments received by the closing date and subsequently will post a Response to Comments Memorandum to the metaldehyde Docket. If any comment significantly affects the reregistration decision, EPA also will publish an amendment to the RED in the Federal Register. In the absence of substantive comments requiring changes, the metaldehyde RED will be implemented as it is now presented.

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 review is to be completed by August 3, 2006.
