...it is vital to ensure the quality of natural resources and the health and safety of the people
who use and depend upon the surface water and wetland resources in Bear Creek and Muskegon River.
- Kathy Evans, West Michigan Shoreline Regional Development Commission, 2011
Excavation of the wetlands began in April 2018. Access roads, bank stabilization structures, and the staging areas were constructed in fall 2017.
Sediment to remediate: 44,000 cubic yards
Contaminants: Total petroleum hydrocarbons, lead and other heavy metals
Method: (Relatively) dry excavation
When: Site preparation in 2017, excavation in spring 2018; 1.5 years expected duration, including habitat restoration
Partners: U.S. Environmental Protection Agency and Michigan Department of Environmental Quality
Notes: A small portion (about 1,400 cubic yards) of sediment was hazardous for lead and was stabilized to non-hazardous conditions before removal.
Cleanup at the Zephyr site is located in the wetlands of the former Zephyr Oil Refinery just south of Holton Rd. (M120) and east of the railroad tracks (cleanup area denoted in yellow in the figure below). MDEQ is conducting additional cleanup efforts in the upland portion of the site in collaboration with the U. S. Army Corps of Engineers. The cleanup is entirely on private property.
The project is in the cleanup stage. More technical information will be provided as it becomes available.
