Register for the September NDWAC MDBP Rule Revisions Meeting

EPA is continuing to host meetings with its National Drinking Water Advisory Council (NDWAC) Microbial Disinfection Byproducts Rule (MDBP) Working Group. EPA is currently seeking input to inform potential regulatory revisions of eight National Primary Drinking Water Regulations (NPDWRs) included in MDBP rules. The MDBP rules were identified as candidates for revision as part of the latest Six-Year Review of all of the NPDWRs.

The Working Group will meet on September 20, 2022 from 11:00 am until 6:00 pm Eastern Daylight Savings Time. The September 20th meeting is intended to include a discussion of the current regulatory landscape for the Disinfectants and Disinfection Byproduct Rules (D/DBPRs); an inventory of public water systems subject to the D/DBPRs; and a characterization of problems related to disinfection byproducts. Future meetings are tentatively planned for November 3, and December 13, 2022. Registration can be found here. The agenda will be posted prior to the meeting to the NDWAC MDBP Rule Revisions Working Group website.
