Chemical Phase II-V Rules Presentation

Chemical Phase II-V Rules Presentation given by Kendra Morrison during the MAP’s teleconference training in Riverton, Wyoming in the Spring of 2019. Although the regulation information is accurate, the following provides two updates to the slides: (1) Region 8 now regulates 29 SOCs (excludes dioxin), and (2) the EPA has committed to issue a proposed National Primary Drinking Water Regulation for perchlorate by November 21, 2025, and a final regulation by May 21, 2027, as required by court orders.
