The state is acting with great urgency, Gov. Rick Snyder says.

Nonetheless, the NAACP says it will invite "disruptive civil disobedience" in Flint if the state doesn't present a plan in the next 30 days that includes a deadline for replacing the city's water pipes, Robert Allen of the Detroit Free Press reports.

"The NAACP, having seen the generosity of Americans from one end of this country to the other sending water bottles to Flint, (is) going to call on the people in 30 days to send bodies and conscience to Flint," and engage in a mass demonstration, Cornell Brooks, national president of the National Association for the Advancement of Colored People, told a crowd at the Christ Fellowship Missionary Baptist Church in Flint on Monday, the Freep reports.

He said he expects a "timeline, deadline (and) price tag" for replacing the water lines, the paper says.

Flint residents lack laith in government and its ability to address the crisis with great urgency.

Snyder and Professor Marc Edwards of Virginia Tech, who was instrumental in helping expose the lead problem, have said that it will take time to replace the pipes and the state still needs to identify where all the lead pipes are. The paper reports there are about 5,000 known lead lines, 25,000 lines made of other materials and about 10,000 made of unknown materials.

The Freep reports:

Snyder's office later issued a statement saying that the project to replace lead lines "is proceeding with great urgency," and that part of $28 million approved last month will go toward utilities; $25 million was requested last week for removing lead pipelines.
