Cowlitz County Public Works staff briefed commissioners on three agenda items: a recommended bid award for vertical landfill gas wells, a request for proposals for landfill gas management services, and a final change order for a county striping contract.

Public Works staff said they will ask the board to award Glacier Environmental Services a contract for a headquarters landfill gas collection and control expansion for $1,490,176.49. The scope described by staff calls for 20 vertical wells drilled into the landfill waste: wells roughly 3 feet in diameter, averaging about 110 feet deep with the deepest at approximately 150 feet, and about 18,000 feet of new piping. Staff said the vertical wells are intended to replace or supplement horizontal wells that can fail over time as the landfill settles; extracted gas will be routed to the county’s flares for combustion or future beneficial uses. Staff said pumps in some wells will also collect leachate and deliver it to the leachate management system.

Public Works said it will also publish a request for proposals for landfill gas management services; the existing services contract (executed in 2022) is ending and staff expect multiple bidders. Staff estimated prior multi‑year expenditures on similar services in the general vicinity of $1 million, including design work, and said they will return with actual bids and hourly rate details once proposals are received.

Separately, the department presented a first and final change order for a roadway striping project: an additional $10,586 to cover extra striping requested by staff. Public Works said contractors completed 28.5 additional miles of striping at original bid unit prices.

Ending: The board was scheduled to consider the Glacier Environmental Services award and the RFP and to approve the small change order at its next meeting; staff said they would present bid details and final cost summaries when the procurement processes conclude.
