The Michigan Department of Environment sent a violation notice to Erickson’s Inc. ordering it to clean up limestone and other materials that its tenant spilled into the Detroit River in late November.
According to Local News 4, the dock at the site collapsed on Nov. 26, discharging an unknown amount of crushed limestone into the river, along with asphalt and contaminated soils.
Testing showed contaminant levels in the water were not detectable or well below quality standards, but the company was required to provide a restoration plant and schedule for removing the material from the river. It is also required to “consider action to prevent the exposed shoreline from further erosion,” the news outlet reported.
