EPA Meeting Third Six-Year Review of Regulations

On October 14th (11 am to 5 pm, ET) and 15th (11 am – 4:30 pm, ET), 2020, EPA will hold a public meeting to obtain input on possible revisions to eight microbial and disinfection byproduct (M/DBP) regulations (chlorite, Cryptosporidium, Haloacetic acids, Heterotrophic bacteria, Giardia lamblia, Legionella, Total Trihalomethanes, and viruses).

EPA posted a draft agenda and a pre-publication Federal Register notice for the meeting (final_prepublication_version_mdbp_meeting draft_agenda_mdbp_meeting_web_version).

Text from the enclosed pre-publication Federal Register notice: “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.”

Background

Under the Safe Drinking Water Act as amended in 1996, EPA is required to conduct a review of drinking water regulations every six years, and if appropriate, revise specific regulations.  Previous six-year reviews were concluded in 2003 and in 2010.  In January 2017 EPA published the results from the third six-year review of contaminants.  The outcome of that review was that EPA considered eight National Primary Drinking Water Regulations as candidates for regulatory revision (the eight regulations listed above).  The 2017 Federal Register publication did not propose specific revisions to any current regulation, but rather began the process.
