The county will award to the lowest responsive responsible bidder and reserves the right to make awards by individual items, groups of items, or any combination thereof.

The scope covers disposal of three material streams from three WES treatment facilities (Kellogg Creek, Tri-City, and Hoodland wastewater treatment plants): grit and screenings, dewatered biosolids, and spent hydrogen sulfide media. Based on 2025 disposal data, estimated annual quantities are 936 tons of grit and decant material, 2,219 tons of dewatered biosolids, and 12 cubic yards of spent hydrogen sulfide media. Bidders must possess required permits for receiving and disposing of these specified materials. The contract excludes hauling and transportation services and does not typically require prevailing wage rates.

The estimated annual cost is $500,000, subject to annual escalation using the Consumer Price Index. The contract term is three years with an option to extend for one additional three-year period. Pricing is based on per-ton rates for disposal services.

Bidders must carry Professional Liability insurance of $1,000,000 per occurrence with $2,000,000 annual aggregate; Commercial General Liability of $1,000,000 per occurrence with $2,000,000 annual aggregate; and Automobile Liability of $500,000 per occurrence.
