ITB 2026-42-Landfill Disposal

Clackamas County Procurement Division in Oregon is soliciting competitive bids for landfill disposal services through Invitation to Bid (ITB) #2026-42, with bids due June 3, 2026, at 2:00 PM PST via the BidLocker electronic submission portal. The County seeks to establish contracts with multiple landfills for the disposal of three distinct waste streams: grit from wastewater treatment screenings and solids generated at three treatment plants, dewatered biosolids from the Kellogg Creek and Tri-City wastewater treatment plants, and spent hydrogen sulfide media from air scrubbing operations at the Tri-City facility. Bidders must submit pricing on a per-ton disposal rate basis on an FOB Destination basis, with all taxes and delivery costs included, and must possess all required permits to receive and dispose of the specified materials. All prospective vendors must maintain professional liability insurance of at least $1,000,000 per occurrence with a $2,000,000 annual aggregate, commercial general liability of $1,000,000 per occurrence with a $2,000,000 annual aggregate, and automobile liability of $500,000 per occurrence. The contract term is three years with an option to extend for one additional three-year period, with an anticipated start date of July 1, 2026. Evaluation will be conducted on a lowest responsive and responsible bidder basis, with the County reserving the right to request best and final offers. Key deadlines include May 20, 2026, for protests of specifications and May 27, 2026, for requests for clarification.

The procurement documents do not identify any set-asides for small businesses, disadvantaged enterprises, or other restricted designations, nor do they reference incumbent contractors or current service providers. The ITB does not specify estimated disposal volumes, identified funding sources, or a budget range for the contract award. Other public agencies may purchase services under the same terms and conditions as the awarded contractor, provided the contractor consents to such arrangements. Bids submitted are binding for 120 days from the submission date, and bidders' responses remain valid through this period unless otherwise rescinded by the contractor.
