Governor Rick Snyder and water experts are proposing that the state institute the country’s toughest lead-testing rules in the wake of Flint’s water emergency.
They’re also recommending the replacement of all lead service pipes within a decade.
The Associated Press was given a copy of the sweeping plan by the governor’s office before Friday’s announcement in Flint.
Other recommendations would require utilities to test all schools and day care centers – not just houses. Lead plumbing disclosures would be mandatory in home sales.
Federal rules require systems to take steps to control corrosion if lead concentrations exceed 15 parts per billion in more than 10 percent of sampled taps. Michigan would move to a limit of 10 parts per billion by 2020.
