Michigan considering tougher copper, lead pipe regulations

Michigan Gov. Rick Snyder has proposed tightening the state’s lead level guidelines to 10 parts per billion by 2020, stricter than the current federal mark of 15 ppb. The proposed change, announced at a meeting of the Flint Water Interagency Coordinating Committee, is part of a package of proposals that also includes annual water testing at day care centers and schools as well as a requirement that local governments create inventories of lead water pipes and then develop plans to replace them.

Critics of both Snyder’s plan and the federal Lead and Copper Rule say neither addresses the true lead danger level of 5 ppb. The U.S. Environmental Protection Agency is in the process of updating the Lead and Copper Rule, a process that began in 2010. Proposed changes are expected to be submitted to the U.S. Congress in 2017. The rule applies to about 68,000 water utilities nationwide. It requires them to take remedial action to improve pipe corrosion controls or eventually replace lead pipes if 10 percent of sites tested for lead or copper exceed the “action level” of 15 ppb. 

The Michigan proposals require approval by the state Legislature.
