State Regulator Cites Confusion About Federal Protocol (18h 5min, oct 18, 2015 y – 18h 56min, may 16, 2016 y)

Description:

In an email to a Detroit News reporter, MDEQ Director Dan Wyant discusses why there were no corrosion controls in place when the city started using Flint River water. He seems to chalk up the lack of corrosion controls to a misunderstanding:

"What has become clear in recent weeks is that the staff believed they were handling the situation in accordance with the proper protocol for a water provider using a new source, but the federal Lead and Copper Rule has a particular provision for communities over 50,000 people; that the system operator must continue treating with full corrosion control even as they test the water.
"What the staff did would have been the proper protocol for a community under 50,000 people. None of the DEQ staff in this division had ever worked on a water source switch for a community of 50,000 people — it's uncommon for big communities to switch sources.
"It's increasingly clear there was confusion here, but it also is increasingly that DEQ staff believed they were using the proper federal protocol here and they were not."

Wyant adds that lime had been added to the water but provided "insufficient corrosion control."
A December email from Snyder's communications director, Meegan Holland, also said that Flint never tested the impact of the Flint River water on the distribution system.
