The CCL serves as the primary source of priority contaminants for research and regulatory evaluations for the Agency's drinking water program. The list is comprised of both chemical and microbial contaminants that are known or anticipated to occur in public water systems, that may have adverse health effects, and which, at the time of publication, are not subject to any proposed or promulgated National Primary Drinking Water Regulations. EPA has formed a CCL Classification Process Work Group of the National Drinking Water Advisory Council (NDWAC) to help the Agency in developing a new risk based priority setting process based upon the recommendations made by the National Research Council (NRC) in its 2001 report.

The work group is comprised of 21 recognized technical experts representing an array of backgrounds and perspectives who are as impartial and objective as possible. The work group is charged with discussing, evaluating, and providing advice on methodologies, activities, and analysis needed to implement the NRC recommendations on an expanded approach for the CCL listing process. This may include advice on developing and identifying: (1) Overall implementation strategy; (2) prototype classification methodology, classification attributes and criteria that should to be used; (3) pilot projects to validate new classification approaches; (4) demonstration studies that explore the feasibility of the VFAR (Virulance-Factor Activity Relationships) approach; (5) risk communication issues; and (6) additional issues not addressed in the NRC report.

The work group has held three meetings thus far: September 18-19, 2002, December 16-17, 2002, and February 5-6, 2003. The September meeting was devoted to gaining understanding of the NRC recommendations from the invited members of the NRC panel, identifying questions, issues and technical expertise needed to fulfill its charge, and planning next steps. During subsequent meetings, the work group formed three activity groups for small group discussions each containing 4-8 members. The three activity groups are: Data Activity Group, Methods Activity Group, and VFAR Activity Group. Each group holds several conference calls for group discussions in between the plenary meetings. The work group has discussed the methods and data to be used for selecting contaminants for the CCL, and the VFAR concept and how the concept can be included in the CCL classification process. In addition, the work group has developed the groups's guiding principles and work plan and identified additional technical needs.

The meetings are open to the public for observation purposes only. Statements from the public will be allowed at the close of each meeting day. EPA is not soliciting written comments and is not planning to formally respond to comments.
