Contra Costa Water District’s (District) Randall-Bold Water Treatment Plant (WTP) and Bollman WTP, on an annual basis, generates an estimated 9,000 cubic yards and 3,000 cubic yards of solids, respectively. The District will pay the disposal fees directly to the disposal facility (Facility). The District contracts with hauling service providers to be responsible for hauling dried solids generated at the treatment plants to an approved Facility. The District is seeking a Facility that accepts dried solids generated during potable water treatment. Solids are dried onsite at the treatment plants before hauling at approximately 45 to 50 percent water content. When a sufficient volume of adequately dried solids has accumulated at the RandallBold WTP or Bollman WTP sites, the District’s Contractor will load and haul the solids to the Facility. The District will comply with California Code of Regulations Title 22 Limits for Hazardous Waste and provide the Facility with the Sampling Standard Operating Procedure for the District’s Water Treatment Plant Solids Disposal. Before hauling is permitted to the Facility, the District will provide the Facility with monitoring results in compliance with Title 22, Section 66261.24(A) Division 4.5, Chapter 11 of the California Code of Regulations (CRR) pertaining to limits for hazardous waste.
