## IV. What Action is EPA Taking in this Notice? 

                    EPA is making available for public viewing the revised risk assessments and related documents for two organophosphate pesticides, chlorpyrifos-methyl and trichlorfon. These documents have been developed as part of the pilot public participation process that EPA and USDA are now using for involving the public in the reassessment of pesticide tolerances under the Food Quality Protection Act (FQPA), and the reregistration of individual organophosphate pesticides under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). The pilot public participation process was developed as part of the EPA-USDA Tolerance Reassessment Advisory Committee (TRAC), which was established in April 1998, as a subcommittee under the auspices of EPA's National Advisory Council for Environmental Policy and Technology. A goal of the pilot public participation process is to find a more effective way for the public to participate at critical junctures in the Agency's development of organophosphate pesticide risk assessments and risk management decisions. EPA and USDA began implementing this pilot process in August 1998, to increase transparency and opportunities for stakeholder consultation. The documents being released to the public through this notice provide information on the revisions that were made to the chlorpyrifos-methyl and trichlorfon preliminary risk assessments, which where released to the public October 6, 1999 (64 FR 193) (FRL-6387-9) for chlorpyrifos-methyl and November 10, 1999 (64 FR 217) (FRL-6393-9) for trichlorfon through notices in the                     **Federal Register**                    .                 

In addition, this notice starts a 60-day public participation period during which the public is encouraged to submit risk management proposals or otherwise comment on risk managements for chlorpyrifos-methyl and trichlorfon. The Agency is providing an opportunity, through this notice, for interested parties to provide written risk management proposals or ideas to the Agency on the chemical specified in this notice. Such comments and proposals could address ideas about how chlorpyrifos-methyl and trichlorfon use sites or crops across the United States or in a particular geographic region of the country. To address dietary risk, for example, commenters may choose to discuss the feasibility of lower application rates, increasing the time interval between application and harvest (“pre-harvest intervals”), modifications in use, or suggest alternative measures to reduce residues contributing to dietary exposure. For occupational risks, commenters may suggest personal protective equipment or technologies to reduce exposure to workers and pesticide handlers. For ecological risks, commenters may suggest ways to reduce environmental exposure, e.g., exposure to birds, fish, mammals, and other non-target organisms. EPA will provide other opportunities for public participation and comment on issues associated with the organophosphate pesticide tolerance reassessment program. Failure to participate or comment 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 proposals must be received by EPA on or before June 27, 2000 at the addresses given under the “ADDRESSES” section. Comments and proposals will become part of the Agency record for the organophosphate pesticides specified in this notice.
