This meeting is open for public listening; click here to register. The August 17th meeting is intended to include a discussion of the current regulatory landscape for the Surface Water Treatment Rules (SWTRs); an inventory of public water systems subject to the SWTRs; and a characterization of problems related to opportunistic pathogens. Future meetings are tentatively planned for September 20th, November 3rd, and December 13th, 2022.

EPA is currently seeking input to inform potential regulatory revisions of eight National Primary Drinking Water Regulations (NPDWRs) included in the MDBP rules. The MDBP rules were identified as candidates for revision as part of the latest Six-Year Review of all of the NPDWRs. As part of the potential regulatory revisions effort, EPA has requested that the NDWAC provide the agency with advice and recommendations on key issues related to potential revisions to MDBP rules. The work of the NDWAC will be supported by an MDBP Rule Revisions Working Group.
