    Stage of Clean-up: Study Underway

    Conditions at proposal (June 24, 1988): The Crazy Horse Sanitary Landfill is on Crazy Horse Canyon Road within the southeastern portion of the hilly region in Salinas in northern Monterey County, California. The 125-acre site is owned by the City of Salinas and operated by Salinas Disposal Services. Prior to 1950, the site operated as an open burning dump. Since 1950, it has been a sanitary landfill. In 1977, it received a permit from the California Regional Water Quality Control Board (CRWQCB) to accept residential, commercial, and nonhazardous industrial wastes. Some pesticide containers have been disposed of at the facility after triple-rinsing as required by California law. The CRWQCB permit prohibits accepting hazardous waste. According to Firestone Tire & Rubber Co., its plant in Salinas disposed of large quantities of "banbury" wastes (which include rubber materials, carbon black, other fillers, and oils) and mixed solvents (mainly BENZENE and TOLUENE) at the site from the early 1970s to about 1982. In February 1985, CRWQCB sampled three downgradient residential wells. They were found to be contaminated with volatile organic chemicals, including BENZENE and TOLUENE.  More...
