 ENVIRONMENTAL PROTECTION AGENCY

 [OPP-34205; FRL-6393-9]

 
 Organophosphate Pesticides; Availability of Preliminary Risk 
Assessments

  AGENCY:  Environmental Protection Agency (EPA).


[[Page 61333]]


  ACTION:  Notice.

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

  SUMMARY:  This notice announces the availability of documents that 
were developed as part of the EPA's process for making reregistration 
eligibility decisions for the organophosphate pesticides and for 
tolerance reassessments consistent with the Federal Food, Drug, and 
Cosmetic Act (FFDCA), as amended by the Food Quality Protection Act of 
1996 (FQPA). These documents are the preliminary human health risk 
assessments and related documents for trichlorfon, and the preliminary 
human health and ecological risk assessments and related documents for 
dicrotophos. This notice also starts a 60-day public comment period for 
the preliminary risk assessments. Comments are to be limited to issues 
directly associated with the two organophosphates that have the risk 
assessments placed in the docket and should be limited to issues raised 
in those documents. By allowing access and opportunity for comment on 
the preliminary risk assessments, EPA is seeking to strengthen 
stakeholder involvement and help ensure our decisions under FQPA are 
transparent and based on the best available information. The tolerance 
reassessment process will ensure that the United States continues to 
have the safest and most abundant food supply. The Agency cautions that 
these risk assessments are preliminary assessments only and that 
further refinements of the risk assessments will be appropriate for 
some, if not all, of these organophosphate pesticides. These documents 
reflect only the work and analysis conducted as of the time they were 
produced and it is appropriate that, as new information becomes 
available and/or additional analyses are performed, the conclusions 
they contain may change.

  DATES:  Comments on these assessments, identified by the docket 
control number for the particular organophosphate pesticide of 
interest, must be received on or before January 10, 2000. Use the table 
in Unit I.C. of the ``SUPPLEMENTARY INFORMATION'' to determine the 
docket control number.

  ADDRESSES:  Comments may be submitted by mail, electronically, or in 
person. Please follow the detailed instructions for each method as 
provided in Unit I.C. of the ``SUPPLEMENTARY INFORMATION.'' To ensure 
proper receipt by EPA, it is imperative that you identify the docket 
control number for the particular organophosphate pesticide of interest 
in the subject line on the first page of your response. Use the table 
in Unit I.C. to determine the docket control number.

  FOR FURTHER INFORMATION CONTACT:  Karen Angulo, Special Review and 
Reregistration Division (7508C), Office of Pesticide Programs, 
Environmental Protection Agency, 401 M St., SW., Washington, DC 20460;

 II. Background

     EPA is making available preliminary risk assessments that have 
been developed as part of EPA's process for making reregistration 
eligibility decisions for the organophosphate pesticides and for 
tolerance reassessments consistent with the FFDCA as amended by the 
FQPA. The Agency's preliminary risk assessments for two organophosphate 
pesticides are available in the individual organophosphate pesticide 
dockets: Dicrotophos and trichlorfon.
     Included in the individual organophosphate pesticide dockets are 
the Agency's preliminary risk assessments. As additional comments, 
reviews, and risk assessment modifications become available, these will 
also be docketed for the two organophosphate pesticides listed in this 
notice. The Agency cautions that these risk assessments are preliminary 
assessments only and that further refinements of the risk assessments 
will be appropriate for the two organophosphate pesticides. These 
documents reflect only the work and analysis conducted as of the time 
they were produced and it is appropriate that, as new information 
becomes available and/or additional analyses are performed, the 
conclusions they contain may change.
     As the preliminary risk assessments for the remaining 
organophosphate pesticides are completed and registrants are given a 
30-day review period to identify possible computational or other clear 
errors in the risk assessments, these risk assessments and registrant 
responses will be placed in the individual organophosphate pesticide 
dockets. A notice of availability for subsequent assessments will 
appear in the Federal Register.
     The Agency is providing an opportunity, through this notice, for 
interested parties to provide written comments and input to the Agency 
on the preliminary risk assessments for the pesticides specified in 
this notice. Such comments and input could address, for example, the 
availability of additional data to further refine the risk assessments, 
such as percent crop treated information or submission of residue data 
from food processing studies, or could address the Agency's risk 
assessment methodologies and assumptions as applied to these specific 
chemicals. Comments should be limited to issues raised within the 
preliminary risk assessments and associated documents. EPA will provide 
other opportunities for public comment on other science issues 
associated with the organophosphate tolerance reassessment program. 
Failure to comment on any such issues as part of this opportunity will 
in no way prejudice or limit a commenter's opportunity to participate 
fully in later notice and comment processes. All comments should be 
submitted by January 10, 2000, at the address given under Unit I.C. 
Comments will become part of the Agency record for each individual 
organophosphate pesticide to which they pertain.
