AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Notice.

SUMMARY:

This notice announces the availability of EPA's Health Effects risk assessment, and related documents for the carbamate pesticide aldicarb, and opens a public comment period on these documents. EPA's Environmental Risk assessment has previously been released for public comment. The public is encouraged to suggest risk management ideas or proposals to address the risks identified. EPA is developing a Reregistration Eligibility Decision (RED) for aldicarb through a modified, 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.

If you have any questions regarding the applicability of this action to a particular entity, consult the person listed under FOR FURTHER INFORMATION CONTACT.

B. What Should I Consider as I Prepare My Comments for EPA?

1. Submitting CBI. Do not submit this information to EPA through www.regulations.gov or e-mail. Clearly mark the part or all of the information that you claim to be CBI. For CBI information in a disk or CD ROM that you mail to EPA, mark the outside of the disk or CD ROM as CBI and then identify electronically within the disk or CD ROM the specific information that is claimed as CBI. In addition to one complete version of the comment that includes information claimed as CBI, a copy of the comment that does not contain the information claimed as CBI must be submitted for inclusion in the public docket. Information so marked will not be disclosed except in accordance with procedures set forth in 40 CFR part 2.

2. Tips for preparing your comments. When submitting comments, remember to:

i. Identify the document by docket ID number and other identifying information (subject heading, Federal Register date and page number).

ii. Follow directions. The agency may ask you to respond to specific questions or organize comments by referencing a Code of Federal Regulations (CFR) part or section number.

iii. Explain why you agree or disagree; suggest alternatives and substitute language for your requested changes.

iv. Describe any assumptions and provide any technical information and/or data that you used.

v. If you estimate potential costs or burdens, explain how you arrived at your estimate in sufficient detail to allow for it to be reproduced.

vi. Provide specific examples to illustrate your concerns, and suggest alternatives.

vii. Explain your views as clearly as possible, avoiding the use of profanity or personal threats.

viii. Make sure to submit your comments by the comment period deadline identified.

II. Background

A. What Action is the Agency Taking?

EPA is releasing for public comment its human health risk assessment and related documents for aldicarb, a carbamate pesticide, and soliciting public comment on risk management ideas or proposals. Aldicarb is registered for use as a systemic insecticide, acaricide and nematicide on agricultural crops including citrus, cotton, dry beans, peanuts, pecans, potatoes, sorghum, soybeans, sugar beets, sugarcane, sweet potatoes, and seed alfalfa (CA). In addition, aldicarb may be applied to field grown ornamentals (CA) and tobacco, and on coffee grown in Puerto Rico. The types of plant pests controlled by aldicarb include leaf phylloxera, bud moth, citrus nematode, aphids, mites (citrus red, citrus rust, Texas citrus), white flies, thrips, fleahoppers, leafminers, leafhoppers, overwintering boll weevil (adults feeding on foliage), lygus, nematodes, cotton leaf perforator, seedcorn maggot, Mexican bean beetle, flea beetles, Colorado potato beetle, greenbug, chinch bug, three cornered alfalfa hopper (suppression), and sugar beet root maggot.

The largest uses of aldicarb are peanuts, sweet potatoes, cotton, potatoes, and citrus. Aldicarb is a restricted use pesticide (RUP), and may be applied only in occupational settings by certified applicators. There are no products containing the active ingredient aldicarb which are intended for sale to homeowners or for occupational use in non-occupational settings (e.g., turf or golf course). EPA developed the risk assessment and risk characterization for aldicarb through a modified version of its public process for making pesticide reregistration eligibility and tolerance reassessment decisions. Through these programs, EPA is ensuring that pesticides meet current standards under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and the Federal Food, Drug, and Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 1996 (FQPA).

Aldicarb is formulated and marketed solely as a granular pesticide. Aldicarb in a vinyl binder coating is adhered to either a corn cob grit or gypsum substrate; these two substrates produce less dust than typical clay substrates used for granular pesticides. Only the gypsum granular is available in closed loading systems. The formulations consist of 5, 10 and 15% granular, which are applied early in the growing season, either pre-plant, at-planting, or early post-emergent, using ground application equipment. Labels specify use of positive displacement application equipment and immediate soil incorporation.

For most crops, only one aldicarb application per season is allowed, but 2 or 3 split applications are permitted on sugar beets. The pre-harvest intervals (PHIs) are generally long due to the early application timing, ranging from 80 to 150 days when specified.

EPA is providing an opportunity, through this notice, for interested parties to provide comments and input on the Agency's risk assessments for aldicarb. Such comments and input could address, for example, the availability of additional data to further refine the risk assessments, such as, additional toxicological data, worker exposure data, and usage information, or could address the Agency's risk assessment methodologies and assumptions as applied to this specific pesticide.

Through this notice, EPA also is providing an opportunity for interested parties to provide risk management proposals for aldicarb. Risks of concern associated with the use of aldicarb are: acute dietary risk estimates for the general U.S. population and all population subgroups at the 99.9th percentile of exposure; acute aggregate food and water risk estimates for adults and children; and worker risk estimates for most mixers, loaders and Start Printed Page 28695applicators. In addition, EPA is providing interested parties an opportunity to submit risk management proposals for ecological risks of concern including those to birds, mammals, fresh water and marine fish and invertebrates. In targeting these risks of concern, the Agency solicits information on effective and practical risk reduction measures.

EPA seeks to achieve environmental justice, the fair treatment and meaningful involvement of all people, regardless of race, color, national origin, or income, in the development, implementation, and enforcement of environmental laws, regulations, and policies. To help address potential environmental justice issues, the Agency seeks information on any groups or segments of the population who, as a result of their location, cultural practices, or other factors, may have atypical, unusually high exposure to aldicarb, compared to the general population.

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, the Agency is tailoring its public participation process to be commensurate with the level of risk, extent of use, complexity of the issues, and degree of public concern associated with each pesticide. For aldicarb, a modified, 4-Phase process with one comment period and ample opportunity for public consultation seems appropriate in view of its refined risk assessment. However, if as a result of comments received during this comment period EPA finds that additional issues warranting further discussion are raised, the Agency may lengthen the process and include a second comment period, as needed, the decisions presented in the RED may be supplemented by further risk mitigation measures when EPA considers its cumulative assessment of the carbamate pesticides.

All comments should be submitted using the methods in ADDRESSES, and must be received by EPA on or before the closing date. Comments will become part of the Agency docket for aldicarb. Comments received after the close of the comment period will be marked “late.” EPA is not required to consider these late comments.

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 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.
