DOCUMENT ACTION: Notice.
2,4-DB (4-2,4-Dichlorophenoxy) butyric acid and 2,4-DB-DMAS (Dimethylamine 4-2,4-Dichlorophenoxy) Butyrate Reregistration Eligibility Decision
This notice announces the availability of EPA's Reregistration Eligibility Decision (RED) for the pesticide 2,4DB (42,4
dichlorophenoxy) butyric acid and 2,4DBDMAS (dimethylamine 42,4 dichlorophenoxy) butyrate. The Agency's risk assessments and other related documents also are available in the 2,4DB butyric acid and 2,4DBDMAS butyrate docket. 2,4DB is a member of the chlorophenoxy class of herbicides which function by mimicking the action of auxins, plant growth hormones. 2,4DB is used to control broadleaf weeds in alfalfa, clover, soybeans, peanuts, peppermint, spearmint, and birdfoot trefoil. 2,4DB is manufactured as an acid and as the dimethylamine salt, 2, 4DBDMAS. EPA has reviewed 2,4DB butyric acid and 2,4DB DMAS butyrate 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.
2,4-DB (4-2,4-Dichlorophenoxy) butyric acid 2,4-DB-DMAS (Dimethylamine 4-2,4-Dichlorophenoxy) butyrate,
I. General Information
A. Does this Action Apply to Me?
This action is directed to the public in general, and may be of interest to a wide range of stakeholders including environmental, human health, and agricultural advocates; the chemical industry; pesticide users; and members of the public interested in the sale, distribution, or use of pesticides. Since others also may be interested, the Agency has not attempted to describe all the specific entities that may be affected by this action. If you have any questions regarding the applicability of this action to a particular entity, consult the person listed under FOR FURTHER INFORMATION CONTACT.

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, 2,4DB butyric acid and 2,4DBDMAS butyrate under section 4(g)(2)(A) of FIFRA. 2,4DB and 2,4DBDMAS are chlorophenoxy herbicides used to control broadleaf weeds in alfalfa, clover, soybeans,
peanuts, peppermint, spearmint, and birdfoot trefoil. Enduse products are formulated as soluble, emulsifiable, or flowable concentrates and can be applied aerially or on the ground. EPA has determined that the data base to support reregistration is substantially complete and that products containing 2,4DB butyric acid and 2,4DBDMAS butyrate are eligible for reregistration, provided the risks are mitigated either in the manner described in the RED or by another means that achieve 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 productspecific data), EPA will make a final reregistration decision under section 4(g)(2)(C) for products containing 2,4DB butyric acid and 2,4DBDMAS butyrate.
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 2,4DB butyric acid and 2,4DBDMAS butyrate tolerances included in this notice.
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 of May 14, 2004 (69 FR 26819) (FRL73579), 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, 2,4DB butyric acid and 2,4 DBDMAS butyrate was reviewed through the modified 4Phase public participation process. Through this process, EPA worked extensively with stakeholders and the public to reach the regulatory decisions for 2,4DB butyric acid and 2,4DBDMAS butyrate.
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. Another comment period is not needed because all issues related to this pesticide were resolved through consultations with stakeholders. The Agency therefore is issuing the 2,4DB butyric acid and 2,4DBDMAS butyrate RED without a comment period.
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 productspecific data on individual enduse 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.
