Michigan flooding displaces thousands, encroaches on chemical plant

Rising floodwaters unleashed by two dam failures submerged parts of the central Michigan town of Midland on Wednesday, displacing thousands of residents and spreading into a Dow Chemical Co plant in the riverfront city.

By late morning, the company said, floodwaters were confirmed to be "comingling with on-site containment ponds" at the sprawling Dow plant, located just upstream from a Superfund hazardous waste cleanup site on the rain-swollen Tittabawassee River.

The National Weather Service (NWS) warned of "life-threatening" flooding as the Tittabawassee rose to historic levels.

Parts of Midland, a city of some 42,000 residents about 193 kilometers northwest of Detroit, were submerged under 1.5 meters of water before the river crested a few feet lower than expected.

Mark Bone, chairman of the Midland County Board of Commissioners, said no injuries had been reported. But the flood posed a major logistical challenge to authorities already coping with the coronavirus pandemic, and Governor Gretchen Whitmer called for federal assistance.

Some 10,000 people were evacuated throughout Midland County, Whitmer said, after days of heavy rain caused the Tittabawassee to overflow its banks and breach the Edenville and Sanford dams on Tuesday.

"Experts are describing this as a 500-year event," Whitmer told a news conference after a tour of the flood zone. She urged residents of low-lying areas to seek higher ground.

National Guard troops assisted in moving some evacuees out of harm's way.

At an evacuation shelter inside Midland High School, about 3 kilometers from the riverfront, volunteers and evacuees wore face coverings to maintain social distancing recommended for curbing spread of the coronavirus. 

One evacuee, 101-year-old Dot Costello, who fled her apartment with neighbor friends on Tuesday, said she was doing "fine," but wished she "had a TV to watch the news."

A spokeswoman for the Federal Energy Regulatory Commission said engineers would be sent to both dams to assist authorities in an investigation into the cause of the breaches. The agency in 2018 revoked the hydropower-generating license for the Edenville structure, accusing its operators of various deficiencies.

Video footage of the flood zone showed high water lapping around buildings in downtown Midland, partly submerging bridges and roads. Several residents were seen kayaking through flooded streets.

Dow Chemical, headquartered in Midland, said in a statement that all operating units, except for facilities needed for managing chemical containment, had been shut down.

The 770-hectare Dow facility sits just upstream from a site contaminated with highly toxic chemicals, including dioxins, spewed from the plant for decades during the manufacture of chlorine-based products, according to the US Environmental Protection Agency.

A multi-year project to clean up the waste under the EPA's Superfund program is likely to be completed in 2021.

The EPA said in a statement its cleanup plan required Dow to conduct "post-flood assessment to determine if there is recontamination or if the constructed cleanup remedies have been damaged." An EPA assessment following a major flood in 2017 found that "impacts to the Superfund site were minimal," and Dow completed "necessary, minor repairs as required."
