          - [OPP-34237; FRL-6765-3] 

# AGENCY: 

Environmental Protection Agency (EPA). 

# ACTION: 

Notice.

# SUMMARY: 

This notice announces the availability of documents that were developed as part of EPA's pilot public participation process for making reregistration eligibility decisions for the organophosphate and certain other, non-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 assessment and related documents for atrazine. This notice also starts a 60-day public comment period for the preliminary risk assessment. Comments are to be limited to issues directly associated with the one pesticide that has risk assessment documents 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 assessment, 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 risk assessments at this stage are preliminary assessments only and that further refinements of the risk assessments may be appropriate for this pesticide.   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.

## II.  Background 

EPA is making available preliminary risk assessments that have been developed as part of EPA's pilot process for making reregistration eligibility decisions for the organophosphate and other pesticides and for tolerance reassessments consistent with the FFDCA, as amended by the FQPA.  The Agency's preliminary human health risk assessment and other related documents for atrazine  are available in the individual pesticide docket. As additional comments, reviews, and risk assessment modifications become available, these will also be docketed for atrazine. 

The Agency cautions that these risk assessments are preliminary assessments only and that further refinements of the risk assessment may be appropriate for atrazine. 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 ecological risk assessment for atrazine is completed and registrants complete a 30-day review period to identify possible computational or other clear errors in the risk assessment, this risk assessment and registrant responses will be placed in the individual pesticide docket.  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 assessment for the chemical specified in this notice.  Such comments and input could address, for example, the availability of additional                           ( print page 10289)                        data to further refine the risk assessment, 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 this specific chemical.  Comments should be limited to issues raised within the preliminary risk assessment and associated documents.  EPA will provide other opportunities for public comment on other science issues associated with the pesticide 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 April 16, 2001 using the methods in Unit I. of the                     **SUPPLEMENTARY INFORMATION**                    .  Comments will become part of the Agency record for atrazine.
