RFP #2026-12 land application services

Clackamas County Board of County Commissioners, on behalf of Water Environment Services (WES), is issuing RFP #2026-12 for Land Application Services to procure vendors to provide land application of Class B dewatered biosolids generated by the Kellogg Creek and Tri-City Wastewater Treatment Plants at agricultural sites throughout Oregon. The service scope encompasses all equipment, labor, and services necessary to land apply biosolids currently transported to Sherman County, with potential expansion to the Willamette Valley during summer and fall months. Based on 2025 production data, the Tri-City WWTP generates approximately 7,000 wet tons annually, with approximately 1,300 acres treated in 2025 across six fields, though the number of required fields is not guaranteed. Proposers must demonstrate experience providing similar services to public entities of comparable size within the past five years and provide three references, including one newly engaged client within thirty-six months and one long-term client. Contractors must supply all equipment, including spreaders and loaders, maintain preventative maintenance programs, utilize GPS-guided land application technology with field mapping capabilities, and comply with all applicable regulations including OAR 340 Division 50, 40 CFR 501 and 503, and DEQ Land Application Authorizations. The question submission deadline is March 18, 2026, at 5:00 PM Pacific Time, with specifications protests due by March 3, 2026, at 5:00 PM Pacific Time. Proposals must be submitted electronically via Bid Locker by March 25, 2026, at 2:00 PM Pacific Time, and the contract term shall be five years from the effective date.

The RFP does not specify any set-aside designations or restrictions limiting bidder eligibility to disadvantaged enterprises or other protected classes. No incumbent vendors or current contractors are identified in the available documentation. Contractors must maintain comprehensive insurance coverage including Professional Liability ($1,000,000/$2,000,000), Commercial General Liability ($1,000,000/$2,000,000), Automobile Liability ($500,000), and Pollution Liability ($1,000,000), and no subcontractors may be used for principal duties without prior written approval from WES. Land application operations are permitted between 7:00 AM and 7:00 PM Pacific Standard Time, Monday through Friday, unless otherwise approved. Pricing shall be provided as land application rates per wet ton with additional hourly rates for equipment usage; the County anticipates biosolids production similar to 2025 totals with an estimated two percent annual increase. While specific award values or budget ranges are not disclosed in the available materials, the anticipated volume of approximately 7,000 wet tons annually with potential for expansion provides a basis for cost estimation by prospective vendors.
