SUPPLEMENTARY INFORMATION: The comment period for the Announcement of the Results of EPA's Review of Existing Drinking Water Standards and

Request for Public Comment and/or Information on Related Issues (Six-

Year Review 2) now ends July 1, 2010. This is an extension of 30 days beyond the comment period established in the Federal Register on March 29, 2010. Anyone seeking to submit comments must follow the procedures specified in section I.C of the announcement as published in the

Federal Register (75 FR 15500, March 29, 2010).

The Safe Drinking Water Act (SDWA) requires the United States

Environmental Protection Agency (EPA) to conduct a periodic review of existing National Primary Drinking Water Regulations (NPDWRs) and determine which, if any, need to be revised. The purpose of the review, called the Six-Year Review, is to identify those NPDWRs for which current health effects assessments, changes in technology, and/or other factors provide a health or technical basis to support a regulatory revision that will improve or strengthen public health protection. EPA has completed its detailed review of 71 NPDWRs and at this time believes that four NPDWRs are candidates for regulatory revision. These four NPDWRs are acrylamide, epichlorohydrin, tetrachloroethylene, and trichloroethylene. EPA requests public comment and/or relevant information that will assist the Agency as we move forward with regulatory action to revise these four NPDWRs. In addition to the 71

NPDWRs discussed in detail in today's action, this review also includes 14 other NPDWRs that need no detailed review because of recent or ongoing revision actions. See the results as published in Federal

Register (75 FR 15500, March 29, 2010).

Dated: May 24, 2010.
