Columbus Oil Turn-key Well Plug. Project Cass Cty

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) is soliciting proposals for the Columbus Oil Turn-key Well Plug project, which covers plugging and abandoning 22 orphan oil and gas wells in Cass County, with proposals due November 17, 2026. Davis-Bacon prevailing wage rates apply to all contractors and subcontractors, and the wage determination expires November 28, 2026.

Scope includes site clearing, rig setup, wellbore cleaning and electronic logging, and cementing to seal zones and protect freshwater aquifers. It also covers removal of abandoned tanks and vessels, flowlines, electrical lines, buildings, and secondary containments, followed by final grading, mulching, and seeding. The wage determination sets 18 job classifications, with hourly wages from $20.00 to $55.00 and fringe benefits from $12.00 to $69.00 per hour. Crane Operator pays $55.00 hourly plus $30.00 fringe, Cementer pays $39.00 hourly plus $46.00 fringe, and Welder pays $41.00 hourly plus $40.00 fringe.

Bidders must submit quantity estimates and unit prices for every Schedule B line item, including contractor supervision, equipment rental, wellhead equipment, drilling fluids, cementing, wireline, waste disposal, and transportation, even for items not expected to be used. Pricing must assume 10-hour workdays and a project timeline. Bidders must obtain EGLE Project Manager approval before mobilizing or charging for any item not pre-approved or for specialized equipment. Invoicing is limited to one Contractor Site Supervisor per day unless otherwise authorized, and double-billing is prohibited when rig crews perform general labor. An overhead percentage applies only to materials or services not already listed, and never to listed hourly or daily rates. The matrix serves as the baseline rate structure for invoicing and must account for change orders or conversion to time-and-materials billing.

Qualified contractors must demonstrate well plugging experience, environmental regulatory compliance, and capacity to manage multiple sites concurrently. Proposals must address technical approach, equipment capabilities, timeline, and qualifications. The contract value and term are not established in the project documents, and the contract term and renewals depend on project completion schedules and funding availability. The project documents identify the place of performance as Cass County, Michigan, while the jurisdiction field lists Calhoun County, and the project description file references Columbus, Ohio.
