DETROIT, MI — A Muskegon firm will pay $66,000 to the state of Michigan this month for violations of state environmental law following a major failure of the company’s Detroit dock, which collapsed into Detroit River last fall.

Revere Dock LLC owner Steve Erickson of North Muskegon has signed a settlement with the Michigan Department of Environment, Great Lakes and Energy (EGLE) that outlines plans to restore and upgrade the site, which partly sank into the river on Nov. 26, 2019.

The state announced the settlement Oct. 12 and said Erickson has until summer to finish restoration work at the 5851 West Jefferson Avenue property. Upgrades include a new 600-foot steel seawall to replace the old wood and concrete dock that collapsed after a large pile of construction aggregate was placed near the shoreline.

The collapse initially sparked fears of contaminated drinking water because the site was used in the 1940s and 1950s for atomic bomb material development. Testing by the Great Lakes Water Authority and EGLE subsequently found no excessive levels of radioactivity.

EGLE and U.S. Environmental Protection Agency testing also found industrial contaminants in site soils and sediment at the site collapse, but not at excessive levels.

The site is the former location of Revere Copper and Brass Co., which operated there for more than 60 years. Erickson has owned the site since 2015 and leased it to Detroit Bulk Storage. It is located next to the Historic Fort Wayne property.

In January, the city of Detroit fined Revere Dock $10,000 for illegally storing limestone at the site without a permit.

Restoration plans follow months of back-and-forth between Revere Dock and EGLE, which called earlier work plans inadequate and directed improvements.

EGLE said Monday it has approved site plans following a June public hearing. Those plans call for
