National Drinking Water Advisory Council Contaminant Candidate List and 6-Year Review of Existing Regulations Working Group Open Meeting

A meeting of the Contaminant Candidate List (CCL) Regulatory Determination and 6-Year Review of Existing Regulations Working Group of the National Drinking Water Advisory Council established under the Safe Drinking Water Act, as amended (42 U.S.C. S300f et seq.), will be held on March 1-2, 2000 beginning at 8:30 AM in the offices of RESOLVE, Suite 275, 1255 23rd Street, NW, Washington, DC 20037. The meeting is open to the public, but due to past experience, seating will be limited.

The purpose of this meeting is for the Working Group to develop and use robust and transparent protocols that can be used for making regulatory determinations from the CCL and for the periodic review of existing NPDWRs. The Working Group will provide specific recommendations for analyzing and presenting the available scientific data, and also recommend methods to identify and document the judgments made to arrive at a conclusion and the supporting rationale.

The CCL and 6-Year Review Working Group will develop specific protocols for making regulatory determinations and selecting existing NPDWRs for possible revision. The Working Group will provide specific recommendations for analyzing and presenting the available scientific data, and also recommend methods to identify and document the judgments made to arrive at a conclusion and the supporting rationale. Due to the statutory deadlines mandated by the SDWA's 1996 amendments, the Working Group will develop a protocol to support CCL regulatory determinations before beginning work on the protocol(s) for the 6-year review of existing NPDWRs.

For CCL regulatory determinations, the Working Group will develop protocols for both chemical and microbial contaminants that will be robust enough to apply to contaminants on the current and future CCLs. As a starting point in developing a protocol, the Working Group will evaluate the draft framework developed by the EPA. This framework will be presented to the group at the first meeting.

The working group members will be asked draft proposed position papers for deliberation by the advisory council, and provide advice and recommendations to the full National Drinking Water Advisory Council. The meeting is open to the public to observe and statements will be taken from the public as time allows.
