Exhibit B - Cost Worksheet.xlsx

This Cost Worksheet (Exhibit B-1) is associated with Contra Costa County Fleet Services Division's Environmental and Hazardous Waste Pick Up contract in California. The worksheet establishes reimbursement rates for contractor services related to the collection and disposal of automotive fluids and hazardous materials. The covered materials include motor oil, gasoline/fuel mixes, diesel/kerosene, transmission fluid, brake fluid, antifreeze/coolant, aerosol lubricants, battery electrolyte, and reactives for incineration, with each item cataloged by its typical waste category classification (flammable liquid, toxic liquid, corrosive liquid, or universal waste). The worksheet also identifies required supplies such as poly drums in various sizes (55-gallon, 30-gallon, and 5-gallon), metal drums, carboys, vermiculite, and box kits, as well as personnel services including annual oil-water separator cleaning and emergency clean-up services.

The cost structure presented in the worksheet utilizes a unit-of-measure based pricing model, with quantities specified per item (primarily 55-gallon quantities for liquids and 1 pallet for certain universal wastes). All line items are marked with "L/P" notation, indicating that specific pricing (per liter or per pallet) would be filled in by the contractor during the bidding process. The worksheet does not include completed pricing information, as this represents a template for contractor cost proposals rather than a final rate schedule.
