BC Cobb Power Plant

Download Data

BC Cobb Power Plant has 23 groundwater monitoring wells, 4 of which have been polluted above federal advisory levels based on samples collected between November 30, 2015 and September 14, 2017. Groundwater at this site contains unsafe levels of molybdenum, arsenic and radium.

Site description

Consumers Energy Company’s BC Cobb Power Plant opened in 1948 and is located near Muskegon, Michigan. It had two coal-fired generating units capable of producing 313 megawatts (MW) of electricity. The plant was shut down in April 2016. There are two CCR units associated with the plant—the Bottom Ash Pond and Ponds 0‐8. From 1984 through plant closure in 2016, coal ash was periodically removed from the ponds and either transported by truck to the JH Campbell Type III landfill (West Olive, Michigan) for disposal or commercially marketed. The BC Cobb Power Plant is listed among the U.S. EPA's potential damage cases, indicating that it has polluted groundwater or surface water at levels which threaten human health and the environment. You can find the industry-reported data here.
