          - [OPP-34225; FRL-6588-7] 

# AGENCY:

Environmental Protection Agency (EPA). 

# 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 and ecological risk assessments and related documents for diazinon. This notice also starts a 60-day public comment period for the preliminary risk assessments. Comments and data are to be limited to issues directly associated with the organophosphate pesticide, diazinon, and its preliminary risk assessments. 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 may be appropriate. These documents reflect only the work and analysis conducted                               ( print page 31903)                            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 and data on these assessments, identified by docket control number OPP-34225, must be received on or before July 18, 2000. 

# ADDRESSES:

                        Comments and data may be submitted by mail, electronically, or in person.

## II. What Action is the Agency Taking? 

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 human health and ecological risk assessments for one organophosphate pesticide are available in the individual organophosphate pesticide docket: Diazinon. 

Included in the individual organophosphate pesticide docket is the Agency's preliminary risk assessments. As additional comments, reviews, and risk assessment modifications become available, these will also be docketed for the one organophosphate pesticide 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 one organophosphate 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. 

                    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 organophosphate pesticide docket for diazinon. 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 data and input to the Agency on the preliminary risk assessments for the chemical specified in this notice. Such comments and data 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 this specific chemicals. Comments and data should be limited to issues raised within the preliminary risk assessments and associated documents. EPA will provide other opportunities for public comment and data on other science issues associated with the organophosphate 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 and data should be submitted by July 18, 2000 at the address given under Unit I. Comments and data will become part of the Agency record for this organophosphate pesticide.
