The Safe Drinking Water Act (SDWA) requires the U.S. Environmental Protection Agency (EPA) to review each national primary drinking water regulation (NPDWR) at least once every six years. As part of the "Six-Year Review", EPA evaluates any newly available data, information, and technologies to determine if any regulatory revisions are needed. During the Agency's third Six-Year Review (Six- Year Review 3) eight NPDWRs were identified as candidates for potential regulatory revision. EPA is hosting a public meeting on October 14 and 15, 2020, to seek public input on the Agency's potential regulatory revisions of these eight NDPWRs including: Chlorite, Cryptosporidium, Haloacetic acids, Heterotrophic bacteria, Giardia lamblia, Legionella, Total Trihalomethanes, and Viruses. The eight NPDWRs are included in the following Microbial and Disinfection Byproduct (MDBP) rules: Stage 1 and Stage 2 Disinfectants and Disinfection Byproducts Rules, Surface Water Treatment Rule, Interim Enhanced Surface Water Treatment Rule, and Long Term 1 Enhanced Surface Water Treatment Rule. At this meeting, EPA is seeking public input on information and perspectives related to the potential regulatory revisions. EPA will consider the data and/or information discussed at this meeting, as well as at future stakeholder engagements, in its determination on whether a rulemaking to revise any MDBP regulations should be initiated. For more information on the meeting visit the EPA's Revisions of the MDBP Rules website: www.epa.gov/dwsixyearreview/revisions-microbial-and-disinfection- byproducts-rules and go to the SUPPLEMENTARY INFORMATION section of this document.
