EPA expressed environmental concerns about shoreline development and potential water quality impacts. Rating EC2.

This action presents EPA's preliminary regulatory determination for perchlorate in accordance with the Safe Drinking Water Act (SDWA). The Agency has determined that a national primary drinking water regulation (NPDWR) for perchlorate would not present ``a meaningful opportunity for health risk reduction for persons served by public water systems.'' The SDWA requires EPA to make determinations every five years of whether to regulate at least five contaminants on the Contaminant Candidate List (CCL). EPA included perchlorate on the first and second CCLs that were published in the Federal Register on March 2, 1998 and February 24, 2005. Most recently, EPA presented final regulatory determinations regarding 11 contaminants on the second CCL in a notice published in the Federal Register on July 30, 2008. In today's action, EPA presents supporting rationale and requests public comment on its preliminary regulatory determination for perchlorate. EPA will make a final regulatory determination for perchlorate after considering comments and information provided in the 30-day comment period following this notice. EPA plans to publish a health advisory for perchlorate at the time the Agency publishes its final regulatory determination to provide State and local public health officials with technical information that they may use in addressing local contamination.

EPA is convening a public workshop to explain the provisions of its recently proposed rule to update and revise the data requirements for registration of antimicrobial pesticides. The workshop is intended to provide an opportunity for members of the public to ask questions about the proposed rule and seek any clarification they believe may assist them in submitting comments to the docket for the proposed rule. Any person wishing to comment on the proposed rule must submit any comments to the docket within the timeframe set forth in the Notice of Proposed Rulemaking.
