Thiram Reregistration Eligibility Decision

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: This notice announces the availability of EPA's Reregistration 
Eligibility Decision (RED) for the pesticide thiram. The Agency's risk

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, thiram under section 4(g)(2)(A) of FIFRA. EPA has determined 
that the data base to support reregistration is substantially complete 
and that products containing thiram are eligible for reregistration 
depending on their specific uses, provided the risks are mitigated 
either in the manner described in the RED.
    Thiram is a member of the dithiocarbamate class of non-systemic 
fungicides. It is used as a fungicide to prevent crop damage in the 
field and to protect harvested crops (apples, peaches, and 
strawberries) from deterioration in storage or transport. It is also 
used as a seed protectant (e.g., small seeded vegetables, large seeded 
vegetables, cereal grains and other seeds, coniferous seeds, cotton 
seed, ornamental seeds, and soybeans) and to protect turf from fungal 
diseases. In addition, thiram is used as an animal repellent to protect 
crops from damage by rabbits, rodents, and deer. Thiram is available in 
a variety of formulations including dust, wettable powder, water 
dispersable granule, flowable concentrate, dry flowable, soluble 
concentrate, and ready-to-use liquid. Thiram is applied both by 
commercial seed treaters and on-farm applicators.
    An aggregate risk assessment looks at the combined risk from 
dietary exposure (food and drinking water pathways) as well as 
exposures from non-occupational sources (e.g., residential uses). Acute 
risks from aggregate exposures are not of concern, due to removal of 
strawberries from the label, a voluntary request for cancellation of 
apple uses, and requests for voluntary cancellation of most residential 
uses. Short-term aggregate risks are not of concern. The Agency 
concludes with reasonable certainty that aggregate exposure to food and 
drinking water will not result in an unacceptable chronic risk. The 
Agency's human heath risk assessment indicates no risks of concern. 
Thiram will no longer be available for sale or use by homeowner 
applicators. As such, all residential risks were calculated related to 
the non-residential turf uses that include golfing for adults and 
toddler exposures in areas that can be treated with thiram by certified 
pesticide applicators. No risk mitigation measures are required to 
address this scenario.
    To protect children from scenarios of concern for exposure to 
thiram-treated turf and to further protect from exposure to ornamentals 
treated with thiram as a deer repellent, the Agency is requiring label 
modifications as outlined in the RED.
    The Agency calculated the potential exposure and risk to pesticide 
handlers from 28 major occupational exposure scenarios based on the 
types of equipment and techniques that potentially can be used for 
thiram applications. For the most part, current label requirements (for 
personal protection single layer clothing, gloves, and no respirator) 
appear to be generally adequate. To reduce worker exposure, the Agency 
has determined that the following measures for specific scenarios are 
appropriate and required for reregistration eligibility:
     Comply with label changes with updated Worker Protection 
Standard and other regulations.
     Cancellation of the aerial and hand/spoon applications of 
granular formulations.
     Require water soluble bags be instituted for all wettable 
powder formulations.
     Cancellation of on-farm seed treatment for peanuts.
    Workers can also be exposed to thiram residues by entering 
previously treated areas to perform activities. The Restricted Entry 
Interval (REI) is used by the Agency to manage risks for post-
application workers doing activities that require contact with treated 
surfaces. The REI is the amount of time required after application 
before residues decline to a level so entry into the treated area and 
engaging in any task or activity would not result in exposures which 
are of concern. Current REIs are protective for most crops; however, 
risks for re-entry workers are of concern for very

[[Page 9319]]

high exposure activities. The following mitigation addresses the risks 
of concern for high exposure activities associated with apples and sod:
     Cancellation of all turf applications for turf grown for 
sale or other commercial use such as sod.
     Cancellation of all apple uses.
    The ecological risk assessment for birds shows risks for 
reproductive effects to birds. There is a chronic effect to mammals 
including endangered species. The Agency's assessment suggested that a 
number of endangered species may potentially be impacted by thiram; 
however, this RED includes only risk mitigation for the Attwater's 
Prairie Chicken (Tympanuchus cupido attwateri). The RED outlines 
mitigation measures that address the Agency's ecological risks of 
concern.
    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 thiram 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) (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, thiram was reviewed through 
the full 6-phase public participation process. Through this process, 
EPA worked extensively with stakeholders and the public to reach the 
regulatory decisions for thiram. Tolerances for residues in/on food and 
feed commodities are currently expressed in terms of residues of thiram 
(40 CFR 180.132) per se and are established at 7 parts per million for 
apples, peaches, and strawberries. Seed treatments are considered to be 
non-food uses and therefore do not require a tolerance.
    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. All issues related to this 
pesticide were resolved through consultations with stakeholders. The 
Agency therefore is issuing the Thiram 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 alldata 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.
