II. Reregistration Eligibility Decision

    The Agency has issued a Reregistration Eligibility Decision (RED) 
document for the pesticidal active ingredient dicofol. Under the 
Federal Insecticide, Fungicide, and Rodenticide Act, as amended in 
1988, EPA is conducting a reregistration program to reevaluate existing 
pesticides to make sure they meet current scientific and regulatory 
standards. The data base to support the reregistration of dicofol is 
substantially complete.
    All registrants of products containing the above listed active 
ingredient have been sent the Dicofol RED document and must respond to 
labeling requirements and product specific data requirements within 8 
months of receipt. Products containing other active ingredients will 
not be reregistered until those other active ingredients are determined 
to be eligible for reregistration.
    The reregistration program is being conducted under congressionally 
mandated time frames, and EPA recognizes both the need to make timely 
reregistration decisions and to involve the public. Therefore, EPA is 
issuing this RED as a final document with a 60-day comment period. 
Although the 60-day public comment period does not affect the 
registrant's response due date, it is intended to provide an 
opportunity for public input and a mechanism for initiating any 
necessary amendments to the RED. All comments will be carefully 
considered by the Agency.

III. Background Information

     EPA has determined that products containing dicofol may be 
eligible for reregistration, as specified in the dicofol RED, 
contingent upon results of a dermal toxicity study due to the Agency in 
December 1998. EPA has identified a possible unacceptable occupational 
risk in the dicofol RED. However, the Agency believes that the 
assumptions used to arrive at this conclusion may have led to an 
overestimation of that risk (e.g., 100% dermal absorption). Therefore, 
EPA has found that it is not appropriate to declare dicofol ineligible 
at this time. One key consideration is the fact that the registrants 
will be submitting the dermal toxicity study mentioned above, which may 
be a more appropriate study for regulatory purposes than data currently 
used. Although the Agency would not normally delay a decision for a 
study voluntarily conducted by a registrant outside the RED timeframe, 
three factors make this appropriate here. First, the data will be 
delivered to the Agency very shortly. Second, the registrants have 
committed to significant risk mitigation measures to be implemented 
immediately (listed below), which address risk concern while the new 
data are being developed and evaluated. Third, the registrants have 
submitted a voluntary cancellation request, which will immediately go 
into effect for any dicofol use which is found to have unacceptable 
risk after consideration of the dermal toxicity study. EPA believes 
this process will address dicofol risk in a timeframe that is 
comparable or more rapid than what EPA could achieve through its own 
regulatory process.
    In sum, dicofol risk will be addressed in the interim in the 
following manner:
    To address risks to homeowners, residents, and children:
    \ All residential uses have been eliminated from labels and will be 
voluntarily canceled.
    To address risks to handlers:
    \ Mixers/loaders/applicators must wear additional personal 
protective equipment (PPE), and use enclosed cabs and cockpits.
    \ All wettable powder formulations produced after December 31, 1998 
must be placed in water soluble packaging.
    \ Application with handheld equipment is eliminated for liquid 
    \ Liquid formulations produced after December 31, 1998 must bear 

[[Page 69284]]

requiring closed mixing systems for dry beans.
    To address risks to workers (persons entering treated areas 
following applications of dicofol):
    \ A revised Restricted Entry Interval (REI) will be set, based on 
Dislodgeable Foliar Residue (DFR) data submitted in October, 1998, and 
on the dermal toxicity study being submitted in December, 1998.
    To protect the environment and wildlife:
    \ Dicofol applications are limited to no more than one per year. 
Previously, for some uses, the number of applications allowed per year 
was either unrestricted or limited to 2 or 3 applications per year.
    \ Dicofol applications on citrus will not exceed 3 pounds a.i./acre 
per year. This has been reduced from 8 pounds a.i./acre per year.
    \ Dicofol applications on strawberries will not exceed 2 pounds 
a.i./acre per year. This has been reduced from 2.4 pounds a.i./acre per 
    \ A spray drift and Runoff Caution Statement is being added to the 
label. Also, a statement prohibiting application directly to water is 
being added to the label.
