Drinking Water Rule Promulgation

New rules promulgated or proposed for public water supplies update the provisions of the Michigan Safe Drinking Water Act.  New rules are promulgated under authority conferred on the Director of EGLE by Section 5 of the Safe Drinking Water Act, 1976 PA 399, as amended (Act 399), identified as R 325.10101 through R 325.12820. Modified and new rules are published on the Michigan Office of Administrative Hearings and Rules (MOAHR) website.

Supplying Water to the Public: Proposed PFAS drinking water standards

2019-035 EG: To establish enforceable drinking water standards for per- and polyfluoroalkyl substances (PFAS) found during the 2018 sampling of Michigan’s public drinking water supplies. While the U.S. Environmental Protection Agency has established an unenforceable lifetime health advisory level for total perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), many academia, health officials, and the Agency for Toxic Substances and Disease Registry (ASTDR) deem this advisory level is too high. In addition, the lack of an enforceable standard for PFOS and PFOA and other commonly found PFAS chemicals impairs EGLE’s ability to take enforceable actions to protect human health and the environment.
