Corrective Action Investigation Plan for Corrective Action Unit 232: Area 25 Sewage Lagoons, Nevada Test Site, Nevada, Revision 0

Corrective Action Investigation Plan for Corrective Action Unit 232: Area 25 Sewage Lagoons, Nevada Test Site, Nevada, Revision 0

Date: May 1, 1999
Creator: /NV, USDOE
Description: The Corrective Action Investigation Plan for Corrective Action Unit 232, Area 25 Sewage Lagoons, has been developed in accordance with the Federal Facility Agreement and Consent Order that was agreed to by the U.S. Department of Energy, Nevada Operations Office; the State of Nevada Division of Environmental Protection; and the U. S. Department of Defense. Corrective Action Unit 232 consists of Corrective Action Site 25-03-01, Sewage Lagoon. Corrective Action Unit 232, Area 25 Sewage Lagoons, received sanitary effluent from four buildings within the Test Cell ''C'' Facility from the mid-1960s through approximately 1996. The Test Cell ''C'' Facility was used to develop nuclear propulsion technology by conducting nuclear test reactor studies. Based on the site history collected to support the Data Quality Objectives process, contaminants of potential concern include volatile organic compounds, semivolatile organic compounds, Resource Conservation and Recovery Act metals, petroleum hydrocarbons, polychlorinated biphenyls, pesticides, herbicides, gamma emitting radionuclides, isotopic plutonium, isotopic uranium, and strontium-90. A detailed conceptual site model is presented in Section 3.0 and Appendix A of this Corrective Action Investigation Plan. The conceptual model serves as the basis for the sampling strategy. Under the Federal Facility Agreement and Consent Order, the Corrective Action Investigation Plan will ...

Corrective Action Investigation Plan for the CNTA Subsurface Sites (CAU Number 443), Revision 1

Corrective Action Investigation Plan for the CNTA Subsurface Sites (CAU Number 443), Revision 1

Date: February 1, 1999
Creator: /NV, USDOE
Description: This Corrective Action Investigation Plan (CAIP) describes the U.S. Department of Energy's (DOE's) planned environmental investigation of the subsurface Central Nevada Test Area (CNTA) Corrective Action Unit (CAU) No. 443. The CNTA is located in Hot Creek Valley in Nye County, Nevada, adjacent to U.S. Highway 6, about 48 kilometers (km) (30 miles [mi]) north of Warm Springs, Nevada. The CNTA was the site of Project Faultless, a nuclear device detonated in the subsurface by the U.S. Atomic Energy Commission (AEC) in January 1968. The purposes of this test were to gauge the seismic effects of a relatively large, high-yield detonation completed in Hot Creek Valley (outside the Nevada Test Site) and to determine the suitability of the site for future large detonations. The yield of the Faultless test was between 200 kilotons and 1 megaton. Two similar tests were planned for the CNTA, but neither of them was completed. Based on the general definition of a corrective action investigation (CAI) from Section IV.14 of the Federal Facility Agreement and Consent Order (FFACO), the purpose of the CAI is ''to gather data sufficient to characterize the nature, extent, and rate of migration or potential rate of migration from releases or ...

Fluid Management Plan for the Project Shoal Area, Off-sites Subproject, CAU 447, Revision 0 (with Record of Technical Change No. 1, 2, and 3)

Fluid Management Plan for the Project Shoal Area, Off-sites Subproject, CAU 447, Revision 0 (with Record of Technical Change No. 1, 2, and 3)

Date: April 1, 1999
Creator: /NV, USDOE
Description: The U.S. Department of Energy, Nevada Operations Office (DOE/NV) has initiated the Off-Site Project to characterize the hazards posed to human health and the environment as a result of underground nuclear testing activities at facilities other than the Nevada Test Site (NTS). The Project Shoal Area (PSA) is one of the Off-Sites Project areas located off the NTS, but within the state of Nevada. The PSA is located approximately 48 kilometers (30 miles) southeast of Fallon, Nevada. Four wells were drilled at the PSA in 1996 as part of the site investigation administered through the Federal Facility Agreement and Consent Order (FFACO) (1996). The hydrogeologic data gathered from these wells was used to support the groundwater flow and contaminant transport modeling of the PSA. However, the subsequent evaluation of the groundwater model concluded that further delineation of the subsurface was required to reduce uncertainties in the model. In accordance with the FFACO, an addendum to the Corrective Action Investigation Plan (CAIP) for the proposed PSA subsurface investigation, Corrective Action Unit 447, was developed. The addendum proposed the drilling and construction of four additional wells and the conduct of hydrologic testing at the PSA. This Fluid Management Plan (FMP) provides guidance ...

Housekeeping Closure Report for Corrective Action Unit 212: Area 23 Warehouses E and R Chemical Storage, Nevada Test Site, Nevada

Housekeeping Closure Report for Corrective Action Unit 212: Area 23 Warehouses E and R Chemical Storage, Nevada Test Site, Nevada

Date: May 1, 1999
Creator: /NV, USDOE
Description: The Federal Facility Agreement and Consent Order was entered into by the State of Nevada; U.S. Department of Energy, and the U.S. Department of Defense to identify sites of potential historical contamination and implement corrective actions based on public health and environmental considerations. The facilities subject to this agreement include the Nevada Test Site (NTS), parts of the Tonopah Test Range, parts of the Nellis Air Force Range, the Central Nevada Test Area, and the Project Shoal Area. Corrective Action Sites (CASs) are areas potentially requiring corrective actions and may include solid waste management units, individual disposal, or release sites. Based on geography, technical similarity, agency responsibility, or other appropriate reasons, CASs are grouped together into corrective Action Units (CAUs) for the purposes of determining corrective actions. This report contains the Closure Verification Forms for cleanup activities that were performed at six CASs within CAU 212 on the NTS. The form for each CAS provides the location, directions to the site, general description, and photographs of the site before and after cleanup activities. Housekeeping activities at these sites included removal of debris, drums, batteries, scrap metal, and other material. Based on these activities, no further action is required at these ...

Salmon Site Remedial Investigation Report, Appendix B (Part 1)

Salmon Site Remedial Investigation Report, Appendix B (Part 1)

Date: September 1, 1999
Creator: /NV, USDOE
Description: This Salmon Site Remedial Investigation Report provides the results of activities initiated by the U.S. Department of Energy (DOE) to determine if contamination at the Salmon Site poses a current or future risk to human health and the environment. These results were used to develop and evaluate a range of risk-based remedial alternatives. Located in Lamar County, Mississippi, the Salmon Site was used by the U.S. Atomic Energy Commission (predecessor to the DOE) between 1964 and 1970 for two nuclear and two gas explosions conducted deep underground in a salt dome. The testing resulted in the release of radionuclides into the salt dome. During reentry drilling and other site activities, liquid and solid wastes containing radioactivity were generated resulting in surface soil and groundwater contamination. Most of the waste and contaminated soil and water were disposed of in 1993 during site restoration either in the cavities left by the tests or in an injection well. Other radioactive wastes were transported to the Nevada Test Site for disposal. Nonradioactive wastes were disposed of in pits at the site and capped with clean soil and graded. The preliminary investigation showed residual contamination in the Surface Ground Zero mud pits below the water ...
