Announcement of the Draft Drinking Water Contaminant Candidate List
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The Safe Drinking Water Act (SDWA), as amended in 1996,
requires the Environmental Protection Agency (EPA) to publish a list of
contaminants which, at the time of publication, are not subject to any
proposed or promulgated national primary drinking water regulation
(NPDWR), that are known or anticipated to occur in public water systems
and which may require regulations under the SDWA [section 1412(b)(1)].
The SDWA, as amended, specifies EPA must publish the first list of
contaminants (Drinking Water Contaminant Candidate List, or CCL) not
later than 18 months after the date of enactment, i.e., by February
1998, and every five years thereafter. The SDWA, as amended, also
specifies that the CCL must be published after consultation with the
scientific community, and after notice and opportunity for public
comment. Today's notice announces the draft CCL, provides background on
how it was developed, and seeks comment on various aspects of
developing the final CCL. The CCL will be the source of priority
contaminants for drinking water research, monitoring, guidance
development, and for selection of candidates for drinking water
regulation. The draft CCL includes 58 chemical and 13 microbiological
contaminants.
DATES: Submit comments on or before December 5, 1997.
