Status• Met cleanup goals for Haz. Waste (Class I)

• 98% of Class II contaminated soils removed

• Contaminated GW discovered along the N

• Continuing to unearth unknowns– For Drums Discovered performing final slope

contouring and restoration (Nov 28, 2005)

Project to Date

• Board’s Contractor has removed a total of 382,020 tons of ash, debris, and oil wastes– 173,482 tons of Class I CA hazardous waste– 205,481 tons of Class II waste – 144 tons of altered tires

• Material transported by 15,943 trucks

Volume Analogies• If one was to use the gross 950,000 square feet of

Cal EPA building, waste would be 7.2 feet deep on every floor;

• Using a football field (i.e., 57,600 ft2) waste would be 119 feet deep or up to the 8 floor of the Cal EPA building;

• Using the number of waste haulers to remove the 382,020 tons of material, one could park the trucks end to end from Sacramento to Oakland and back or 150 miles one way.
