EPA met with representatives from the American Water Works Association (AWWA) to discuss the CCL 4 nominated contaminants.  EPA gave a brief summary of the request for nominations from the public in the Federal Register on May 8, 2012, and of the contaminant nominations received from the public.  EPA told the AWWA members that it had received nominations for 59 unique contaminants (54 chemicals and 5 microbial contaminants or groups of contaminants) to be considered for inclusion in the CCL 4.  Eight of those 59 contaminants were nominated by more than one nominator.  Nominations were received from 10 different organizations or individuals.  EPA stated that all of the original nomination submissions could be found in the CCL 4 docket at www.regulations.gov (Docket ID: EPA-HQ-OW-2012-0217).  EPA also said that we are evaluating the nominated contaminants using the same process that was used in CCL 3, and that we are working hard to release a Draft CCL 4 for public comment and to meet our statutory deadline for the Final CCL 4 of October, 2014.  
AWWA members asked how many of the nominated chemicals were previously considered in CCL 3, and EPA responded that 44 of the nominated chemicals were considered in the CCL 3 Universe and that most of the nominated chemicals not in the CCL 3 Universe were previously evaluated by EPA in response to CCL 3 public comments.  EPA also clarified that all of the nominated contaminants that have new data available since the development of the CCL 3 are being evaluated for potential inclusion in the CCL 4.  AWWA members also asked EPA to clarify how contaminants were considered in the CCL 3 process, and EPA gave a brief explanation of the CCL 3 process, which included narrowing of a broad Universe of potential drinking water contaminants to a Preliminary CCL (PCCL) using screening criteria based on the contaminant's potential to occur in public water systems, and the potential for public health concern, and then a more detailed evaluation of the PCCL contaminants using  a scoring and classification system to select contaminants from the PCCL for the CCL.  Members also asked if the Draft CCL 4 would undergo SAB review, and EPA responded that we will consult with the SAB on the Draft list.
