Former Bay City Manufactured Gas Plant Site

History & Location

Located in Bay City, Michigan, the Consumers Energy Company’s Former Bay City Manufactured Gas Plant was used for converting coal and oil to gas for heating and lighting. As a result of industrial activities, MGP-related contaminants impacted the area’s soil. Consumers Energy purchased the plant in 1922 and officially terminated plant operations in 1942.

As the prime contractor, Sevenson worked in conjunction with Consumer’s Energy Company and Soil & Materials Engineering, Inc., to execute environmental remediation activities at two contaminated sections of the property, Area A and Area B.

Significant Project Features

• Mechanical excavation of approximately 17,000 tons of MPG-impacted soil from two separate areas of the Former Bay City Manufactured Gas Plant
• Monitoring of natural methane gas levels and work-related odors during remediation operations to ensure that the project was executed with zero exceedances
• Sevenson constructed, operated, and maintained a temporary 100-GPM Waste Water Treatment Plant (WWTP), which treated and discharged over 4.6M gallons of impacted water
• Sevenson completed over 8,000 safe workhours without a lost-time incident
