EPA is currently seeking input to inform potential regulatory revisions [epa.gov] of eight National Primary Drinking Water Regulations (NPDWRs) included in Microbial and Disinfection Byproducts (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 National Drinking Water Advisory Council (NDWAC), a Federal Advisory Committee (FAC) established under the Safe Drinking Water Act, 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. To read EPA’s charge to the NDWAC and learn more about the Working Group, visit NDWAC MDBP Rule Revisions Working Group website [epa.gov]. The Working Group will meet on November 3, 2022 from 11:00 am until 6:00 pm Eastern Daylight Savings Time. The November 3^rd  meeting is intended to include a discussion of the interdependencies across the Surface Water Treatment Rules and Disinfectants and Disinfection Byproduct Rules; and information on follow-up analyses requested by the Working Group. A future meeting is tentatively planned for December 13, 2022.

Registration for members of the public to listen to the November 3, 2022, virtual meeting is now available here [eventbrite.com]. You will receive a confirmation email upon successful registration and a link to the meeting will be emailed to you no later than November 2, 2022, which will be hosted through Zoom for Government.
