BACKGROUND
The Upper Valley Waste Management Agency (UVWMA) issued a request for proposals (RFP) for waste characterization studies of landfill waste streams from franchised hauler and self-haul loads. The RFP was released on 1/12/26 and proposals were due on 1/30/26.
The maximum $90,000 of funding for this waste characterization study is from the CalRecycle SB 1383 local assistance grant. UVWMA applied for this grant as the lead. The grant awarded funding based on population, as such UVWMA applied as the lead with the entirety of the unincorporated area of Napa County participating as well. The awarded funding is to be expended throughout the UVWMA area and all Napa County unincorporated areas.
Due to the funding purpose, the waste characterization study will also evaluate landfill waste streams that are outside of the UVWMA area. The proposed contractor will evaluate landfill streams at both Clover Flat Landfill and the Devlin Road Transfer Station. This will include evaluations of franchised hauler landfill loads from Upper Valley Disposal Service (UVDS), Berryessa Garbage Service and Napa County Recycling and Waste Services. It will also evaluate self-haul loads at Clover Flat Landfill and the Devlin Road Transfer Station.
This waste characterization study will result in a highly localized report of what materials remain in the landfill waste stream. This will allow staff to determine future waste diversion programs if divertible or reusable materials are in the landfill streams and will allow staff to evaluate the effectiveness of current SB 1383 driven programs to divert organics from the landfill. The study can be used as a baseline, if UVWMA chooses to conduct another waste characterization study in the future after programs are expanded, continued or new programs are established. Staff do not currently have a set of data to evaluate the effectiveness of public programs. The waste characterization study will benefit and improve current and future waste diversion programs throughout UVWMA and Napa County.
UVWMA received five proposals that were complete and submitted by the 1/30/26 deadline. One UVWMA, two Napa County and one UVDS staff person reviewed and scored the submitted proposals. Proposals were scored on: Approach to sampling, measuring, data compilation and assessments; Experience of the proposer and subcontractors; Work plan, deliverables, timetable and Budget plan. SCS Engineers received the highest cumulative score of 369 out of 400. The second ranked proposer received a cumulative score of 320 out of 400. Work will begin after the agreement is authorized and the agreement will end no later than November 1, 2026 to coincide with the close of the SB 1383 Local Assistance Grant.
