Results of EPA's Review of Existing Drinking Water Standards and 
Request for Public Comment and/or Information on Related Issues; 
Extension of the Comment Period

AGENCY: Environmental Protection Agency (EPA).

ACTION: Extension of public comment period.


SUMMARY: The Environmental Protection Agency (EPA) is extending by 30 
days the public comment period for the National Primary Drinking Water 
Regulations; Announcement of the Results of EPA's Review of Existing 
Drinking Water Standards and Request for Public Comment and/or 
Information on Related Issues, which was published in the Federal 
Register on March 29, 2010. The purpose of that notice was to invite 
commenters to submit any new, relevant peer-reviewed data or 
information pertaining to the four NPDWRs identified in that action as 
candidates for revision (i.e. acrylamide, epichlorohydrin, 
tetrechloroethylene and trichloroethylene). This information will 
inform EPA's evaluation as the Agency moves forward with the regulatory 
revisions for these four NPDWRs. This extended comment period will 
afford greater opportunity to all interested parties to review and 
submit comments on the notice.

DATES: Comments must be received on or before July 1, 2010.

2008-0747, by one of the following methods:

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.

Director, Office of Ground Water and Drinking Water.
