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 updates to the slides: (1) Region 8 now regulates 29 SOCs (excludes dioxin), (2) in July 2024 EPA provided results of the fourth cycle of its Six-Year Review for the Chemical Phase II-V Rules, and (3) 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.
