The Corrective Action Plan provides the closure methods for Corrective Action Unit (CAU) 423: Area 3 Building 03-60 Underground Discharge Point (UDP), Tonoopah Test Range, Nevada. CAU 423 consists of the UDP and an associated discharge pipeline extending from Building 03-60. Corrective action investigations were completed in January 1998, and are documented in the Corrective Action Decision Document (US DOE, 1998). Results indicate an asymmetrical hydrocarbon plume, measuring 11 meters (m) 35 ft in length, 6 m (20 ft) in width, and 4 to 20 m (14 to 65 ft) in depth, has formed beneath the UDP and migrated westward. Petroleum hydrocarbon levels were identified above the 100 miligrams per kilogram (mg/kg) action level specified in Nevada Administrative Code (NAC) 445A (NAC 1996). The highest petroleum hydrocarbon concentration detected was 2,4000 mg/kg at 6 m, 20 ft, below surface grade as diesel. Corrective actions will consist of administrative controls and in place closure of th e UDP and its associated discharge pipeline.
