EPA Seeking Nominations for NDWAC MDBP Rules Revisions Working Group

On November 12th, EPA published a Federal Register notice seeking nominations for a new Working Group under the National Drinking Water Advisory Council (NDWAC) that will work to develop consensus recommendations for revisions to the Microbial and Disinfection By-Products (MDBP) Rules. The Working Group process is anticipated to begin in the spring of 2022 and last through mid-2023. With all of the complexities in balancing the microbial and disinfection by-product (DBP) risks, as well as the lack of substantive new data on health effects, occurrence, and risks, developing consensus recommendations will be challenging, even with quality facilitation. EPA’s request for nominations closes on Monday, December 13th, and nominations should be submitted to MDBPRevisions@epa.gov.

On a related note, the NDWAC has a scheduled meeting on December 1st and 2nd, and additional information on that meeting can be found here.
