SAB Drinking Water Committee to Discuss CCL4

EPA’s Science Advisory Board (SAB) Drinking Water Committee (DWC) will meet to review EPA’s Draft Fourth Contaminant Candidate List (CCL4).  The public meeting will be held on April 29, 2015, from 9:00 a.m. to 5:00 p.m. (Eastern Time) and on April 30, 2015, from 9:00 a.m. to 3:30 p.m. (Eastern Time).  The meeting will be held at the George Washington University, Milken Institute School of Public Health, 950 New Hampshire Ave. NW., 7th Floor, Washington, DC 20052. EPA’s Office of Water requested that the SAB Drinking Water Committee review the Draft CCL4, which was released for public review and comment on February 4, 2015 (80 FR 6076). The Safe Drinking Water Act (SDWA), as amended in 1996, requires EPA, after consultation with the scientific community including the SAB and opportunity for public comment, to publish a list every five years of currently unregulated contaminants that are known or anticipated to occur in public water systems and may require regulation under the SDWA (referred to as the Contaminant Candidate List, or CCL).  This list is subsequently used to identify priority contaminants for further research needs and to make determinations on whether or not to regulate at least five contaminants from the CCL with national primary drinking water regulations (NPDWRs).  The draft CCL4 includes 100 chemicals or chemical groups and 12 microbial contaminants.  Comments from the public (including states) on the draft CCL4 are due to EPA on April 6, 2015.Prior to the meeting, the review documents, agenda and other materials will be accessible through the calendar link on the blue navigation bar at
