The Sand Springs Petrochemical Complex is a 235-acre site in Sand Springs, Oklahoma on the northern bank of the Arkansas River. The site includes acid sludge pits, a surface impoundment, spray ponds, solvent and waste lagoons, surficial sludge contamination, solvent and waste oil lagoons and contaminated sediments. While both soil and ground water are contaminated, the Record of Decision addresses surface liquids, sludges and heavily contaminated soils. The primary contaminants of concern are organic pollutants: bis(2-ethylhexyl)phthalate and toluene and inorganic compounds: lead, zinc, chromium and barium. The selected remedial action for the site is onsite thermal destruction of wastes. ARCO Petroleum Products Company proposed a remedy that includes excavation and offsite thermal destruction of sludges; solidification and/or stabilization of all remaining sludges with containment of the resulting matrix in an onsite hazardous waste RCRA cell; and implementation of chemical and physical treatability studies.
