State and federal officials are due in South Boston to brief Southside residents on a massive coal ash spill into the Dan River.
Representatives of the Environmental Protection Agency and public health and water officials from the McAuliffe administration are to brief residents Thursday night on the Duke Energy spill Feb. 2 in North Carolina.
The contamination occurred when a pipe running under a coal ash pond collapsed, spewing into the Dan River up to 82,000 tons of coal ash mixed with 27 million gallons of contaminated water.
Federal prosecutors have served North Carolina's environmental agency with subpoenas seeking documents and ordering state employees to testify before a grand jury.
It is part of a broadening criminal investigation triggered by a massive coal ash spill into the Dan River.
