Summary
This Corrective Action Investigation Plan contains the U.S. Department of Energy, National Nuclear Security Administration Nevada Operations Office's approach to collect the data necessary to evaluate corrective action alternatives appropriate for the closure of Corrective Action Unit (CAU) 271 under the Federal Facility Agreement and Consent Order. Corrective Action Unit 271 consists of 15 Corrective Action Sites (CASs) including: thirteen Septic Systems (25-04-01, 25-04-03, 25-04-04, 25-04-08, 25-04-09, 25-04-10, 25-04-11, 26-04-01, 26-04-02, 26-05-03, 26-05-04, 26-05-05, and 27-05-02), one Contaminated Water Reservoir (26-03-01), and one Radioactive Leachfield (26-05-01). The CASs addressed by CAU 271 are located at Guard Station 500, the Reactor Control Point (RCP), Bare Reactor Experiment - Nevada Tower, and Engine Test State-1 (ETS-1) facilities in Area 25; the Port Gaston and Project Pluto facilities in Area 26; and the Baker Site in Area 27 of the Nevada Test Site. Between 1 958 and 1973, the RCP and ETS-1 facilities supported the development and testing of nuclear reactors for space propulsion as part of the Nuclear Rocket Development Station. The Project Pluto facilities supported nuclear reactor testing for use as a ramjet propulsion system between 1961 and 1964, followed by similar use for other projects through the early 1980s. The Baker Site facilities were constructed in the 1960s to serve as the staging point where the manufactured components of nuclear devices were assembled, disassembled, and modified. The scope of the investigation strategy at these sites will involve biased and random soil sampling in leachfields using excavation (with drilling as a contingency), collection of soil samples underlying the base of proximal and distal ends of septic tanks and distal ends of distribution structures, defining the lateral and vertical extent of contamination through discrete field and possible stepout location sampling, collection system line inspection, and geotechnical/ hydrological laboratory analyses. Based on site history and existing characterization data gathered to support the Data Quality Objectives process, it is believed that the contaminants of potential concern at these CASs may include: volatile organic compounds, fecal coliform bacteria, semivolatile organic compounds, petroleum hydrocarbons, Resource Conservation and Recovery Act metals, gamma-emitting radionuclides, isotopic uranium, strontium-90, tritium, beryllium, polychlorinated biphenyls, pesticides, and herbicides. The results of this field investigation will support a defensible evaluation of corrective action alternatives in the Corrective Action Decision Document.
