Currently there are no proposed rules for the drinking water program.

Under the  Michigan Safe Drinking Water Act, 1976 PA 399, as amended, rules were recently promulgated that include provisions from four federal drinking water regulations:  Radionuclides Rule,   Arsenic and Clarifications to Compliance and New Source Monitoring Rule,  Filter Backwash Recycling Rule,  Long Term 1 Enhanced Surface Water Treatment Rule as well as provisions for Point-of-Use and Point-of-Entry devices. The rules establish an MCL of 30 ug/L for uranium, lowers the MCL for arsenic to 0.010 mg/L, establishes treatment requirements for small systems using surface water or groundwater under the direct influence of surface water that complement the requirements previously established for large systems, and requires systems that recycle backwash to return specific flows through all processes of the existing filtration system. Community water supplies are prohibited from using POU devices, but noncommunity systems may use POU devices with department approval.  The amendments were promulgated on April 6, 2005, except the applicable public notification provisions, which were promulgated on April 29, 2005.

We expect the U.S. EPA will promulgate the following proposed regulations by the end of 2005:  Groundwater Rule, Long Term 2 Enhanced Surface Water Treatment Rule, and Stage 2 Disinfectants and Disinfection Byproducts Rule.  We will begin the state rule promulgation process shortly thereafter.
