Rule Promulgation

As part of a larger statewide effort to reduce lead exposure, DEQ recently underwent rule promulgation efforts to update the Lead and Copper Rule provisions of the Michigan Safe Drinking Water Act. These changes are designed to reduce exposure to lead in drinking water. 

Rule Promulgation Timeline

Rule changes include requirements to remove lead service lines from drinking water distribution systems and lowering the action level for lead, in addition to other protective provisions. These rules were promulgated by authority conferred on the Director of the DEQ 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. The rules (2017-008 EQ) are published on the Office of Regulatory Reinvention’s website.
