DETROIT (WXYZ) — The Michigan Department of Environment, Great Lakes, and Energy is asking for revised planes and more details about the dock collapse at the Revere Copper Site in Detroit.
EGLE says they have additional concerns about the response efforts to prevent soil contaminants from eroding into the river from the collapse site.
They have sent letter to Revere Dock, LLC and Detroit Bulk Storage asking them to provide a written update on additional actions that have been taken by February 7.
EGLE says a 20-foot silt curtain that has been put into place is not preforming satisfactorily, and that the sinkhole has not been evaluated adequately and may be allowing additional materials, including aggregate and contaminated soil, to enter the river.
EGLE wants more assessments and revised procedures submitted to them.
They are also giving the companies until February 29 to submit a progress report and until March 30 to submit a Restoration Plan Report to detail longer-term and more specific plans.
