EPA is making available preliminary risk assessments that have been developed as part of EPA's process for making reregistration eligibility decisions for Bis-2.

                    The Agency is providing the opportunity, through this notice, for interested parties to provide written comments and input to the Agency on the preliminary risk assessments for the chemical specified in this notice.  Such comments and input could address, for example, the availability of additional data to further refine the risk assessments, 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 assessments and associated documents.  EPA will provide other opportunities for public comment on other science issues associated with Bis-2.  Failure to comment on any 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 60 days from the date of the publication of this                     **Federal Register**                     notice.
