Book excerpt: The Area 25 Vehicle Washdown, Corrective Action Unit (CAU) 240, was clean-closed following the approved Corrective Action Decision Document closure alternative and in accordance with the Federal Facility Agreement and Consent Order (FFACO, 1996). The CAU consists of thee Corrective Action Sites (CASs): 25-07-01 - Vehicle Washdown Area (Propellant Pad); 25-07-02 - Vehicle Washdown Area (F and J Roads Pad); and 25-07-03 - Vehicle Washdown Station (RADSAFE Pad). Characterization activities indicated that only CAS 25-07-02 (F and J Roads Pad) contained constituents of concern (COCs) above action levels and required remediation. The COCs detected were Total Petroleum Hydrocarbons (TPH) as diesel, cesium-137, and strontium-90. The F and J Roads Pad may have been used for the decontamination of vehicles and possibly disassembled engine and reactor parts from Test Cell C. Activities occurred there during the 1960s through early 1970s. The F and J Roads Pad consisted of a 9- by 5-meter (m) (30- by 15-foot [ft]) concrete pad and a 14- by 13-m (46-by 43-ft) gravel sump. The clean-closure corrective action consisted of excavation, disposal, verification sampling, backfilling, and regrading. Closure activities began on August 21, 2000, and ended on September 19, 2000. Waste disposal activities were completed on December 12, 2000. A total of 172 cubic meters (223 cubic yards) of impacted soil was excavated and disposed. The concrete pad was also removed and disposed. Verification samples were collected from the bottom and sidewalls of the excavation and analyzed for TPH diesel and 20-minute gamma spectroscopy. The sample results indicated that all impacted soil above remediation standards was removed. The closure was completed following the approved Corrective Action Plan. All impacted waste was disposed in the Area 6 Hydrocarbon Landfill. All non-impacted debris was disposed in the Area 9 Construction Landfill and the Area 23 Sanitary Landfill.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This Corrective Action Decision Document/Closure Report has been prepared for Corrective Action Unit 554, Area 23 Release Site, located in Mercury at the Nevada Test Site, Nevada, in accordance with the ''Federal Facility Agreement and Consent Order'' (1996). Corrective Action Unit (CAU) 554 is comprised of one corrective action site (CAS): (1) CAS 23-02-08, USTs 23-115-1, 2, 3/Spill 530-90-002. The purpose of this Corrective Action Decision Document/Closure Report is to provide justification and documentation supporting the recommendation for closure of CAU 554 with no further corrective action. To achieve this, corrective action investigation (CAI) activities were performed from January 18 through May 5, 2005, as set forth in the ''Corrective Action Investigation Plan for Corrective Action Unit 554: Area 23 Release Site'' (NNSA/NSO, 2004) and Records of Technical Change No. 1 and No. 2. The purpose of the CAI was to fulfill the following data needs as defined during the data quality objective (DQO) process: (1) Determine whether contaminants of concern are present. (2) If contaminants of concern are present, determine their nature and extent. (3) Provide sufficient information and data to complete appropriate corrective actions. The CAU 554 dataset from the investigation results was evaluated based on the data quality indicator parameters. This evaluation demonstrated the quality and acceptability of the dataset for use in fulfilling the DQO data needs. Analytes detected during the CAI were evaluated against preliminary action levels (PALs) established in the CAU 554 CAIP for total petroleum hydrocarbons (TPH) benzo(a)pyrene, dibenz(a, h)anthracene, and trichloroethene (TCE). Specifically: (1) The soil beneath and laterally outward from former underground storage tanks at CAS 23-02-08 contains TPH-diesel-range organics (DRO) above the PAL of 100 milligrams per kilogram, confined vertically from a depth of approximately 400 feet (ft) below ground surface (bgs). The contamination is confined to 12.5 ft bgs to the subsurface media and laterally within approximately 100 ft of the release. (2) A single soil sample collected from the depth of 99 to 100 ft bgs demonstrated the presence of TCE at a concentration above the PAL. (3) Two soil samples collected from depths of 198 to 199 ft bgs and 380 to 382 ft bgs demonstrated the presence of benzo(a)pyrene at a concentration above the PAL. (4) Two soil samples collected from depths of 240 to 241 ft bgs and 290 to 291 ft bgs demonstrated the presence of dibenz(a, h)anthracene at a concentration above the PAL. Tier 2 final action levels (FALs) were then calculated for these contaminants. The Tier 2 FALs for TCE, benzo(a)pyrene, and dibenz(a, h)anthracene were calculated based on a limited exposure to subsurface contamination scenario, and the Tier 2 FAL for TPH-DRO was established as the U.S. Environmental Protection Agency Region 9 Preliminary Remediation Goal values for the individual hazardous constituents of diesel. The evaluation of TPH-DRO, benzo(a)pyrene, dibenz(a, h)anthracene, and TCE based on the Tier 2 FALs determined that no FALs were exceeded. Therefore, the DQO data needs were met, and it was determined that no corrective action (based on risk to human receptors) is necessary for the site. As a best management practice for the remaining subsurface diesel contamination present at the site, a use restriction was imposed on future site activities that would not allow for future contact of the subsurface contamination. Therefore, the U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office provides the following recommendations: (1) No further corrective action for CAU 554. (2) No Corrective Action Plan. (3) A Notice of Completion to the U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office is requested from the Nevada Division of Environmental Protection for closure of CAU 554. (4) Corrective Action Unit 554 should be moved from Appendix III to Appendix IV of the Federal Facility Agreement and Consent Order.

Book excerpt: This Closure Report (CR) describes the activities performed to close CAU 115, Area 25 Test Cell A Facility, as presented in the NDEP-approved SAFER Plan (NNSA/NSO, 2004). The SAFER Plan includes a summary of the site history, process knowledge, and closure standards. This CR provides a summary of the completed closure activities, documentation of waste disposal, and analytical and radiological data to confirm that the remediation goals were met and to document final site conditions. The approved closure alternative as presented in the SAFER Plan for CAU 115 (NNSA/NSO, 2004) was clean closure; however, closure in place was implemented under a Record of Technical Change (ROTC) to the SAFER Plan when radiological surveys indicated that the concrete reactor pad was radiologically activated and could not be decontaminated to meet free release levels. The ROTC is included as Appendix G of this report. The objectives of closure were to remove any trapped residual liquids and gases, dispose regulated and hazardous waste, decontaminate removable radiological contamination, demolish and dispose aboveground structures, remove the dewar as a best management practice (BMP), and characterize and restrict access to all remaining radiological contamination. Radiological contaminants of concern (COCs) included cobalt-60, cesium-137, strontium-90, uranium-234/235/236/238, and plutonium-239/240. Additional COCs included Resource Conservation and Recovery Act (RCRA) metals, polychlorinated biphenyls (PCBs), and asbestos.

Available in PDF, EPUB and Kindle. Book excerpt: This Corrective Action Decision Document identifies and rationalizes the U.S. Department of Energy, Nevada Operations Offices's selection of a recommended corrective action alternative (CAA) appropriate to facilitate the closure of Corrective Action Unit (CAU) 240: Area 25 Vehicle Washdown, Nevada Test Site, Nevada. This corrective action investigation was conducted in accordance with the Corrective Action Investigation Plan for CAU 240 as developed under the Federal Facility Agreement and Consent Order. Located in Area 25 at the Nevada Test Site in Nevada, CAU 240 is comprised of three Corrective Action Sites (CASs): 25-07-01, Vehicle Washdown Area (Propellant Pad); 25-07-02, Vehicle Washdown Area (F and J Roads Pad); and 25-07-03, Vehicle Washdown Station (RADSAFE Pad). In March 1999, the corrective action investigation was performed to detect and evaluate analyte concentrations against preliminary action levels (PALs) to determine contaminants of concern (COCs). There were no COCs identified at CAS 25-07-01 or CAS 25-07-03; therefore, there was no need for corrective action at these two CASs. At CAS 25-07-02, diesel-range organics and radionuclide concentrations in soil samples from F and J Roads Pad exceeded PALs. Based on this result, potential CAAs were identified and evaluated to ensure worker, public, and environmental protection against potential exposure to COCs in accordance with Nevada Administrative Code 445A. Following a review of potential exposure pathways, existing data, and future and current operations in Area 25, two CAAs were identified for CAU 240 (CAS 25-07-02): Alternative 1 - No Further Action and Alternative 2 - Clean Closure by Excavation and Disposal. Alternative 2 was identified as the preferred alternative. This alternative was judged to meet all requirements for the technical components evaluated, compliance with all applicable state and federal regulations for closure of the site, as well as minimizing potential future exposure pathways to the contaminated soils at the F and J Roads Pad at CAU 240.

Corrective Action Unit (CAU) 554 is comprised of one corrective action site (CAS): CAS 23-02-08, USTs 23-115-1, 2, 3/Spill 530-90-002. The purpose of this Corrective Action Decision Document/Closure Report is to provide justification and documentation supporting the recommendation for closure of CAU 554 with no further corrective action. To achieve this, corrective action investigation (CAI) activities were performed from January 18 through May 5, 2005, as set forth in the Corrective Action Investigation Plan for Corrective Action Unit 554: Area 23 Release Site (NNSA/NSO, 2004) and Records of Technical Change No. 1 and No. 2.

(2) If contaminants of concern are present, determine their nature and extent. (3) Provide sufficient information and data to complete appropriate corrective actions. The CAU 554 dataset from the investigation results was evaluated based on the data quality indicator parameters. This evaluation demonstrated the quality and acceptability of the dataset for use in fulfilling the DQO data needs. Analytes detected during the CAI were evaluated against preliminary action levels (PALs) established in the CAU 554 CAIP for total petroleum hydrocarbons (TPH) benzo(a)pyrene, dibenz(a, h)anthracene, and trichloroethene (TCE). Specifically: (1) The soil beneath and laterally outward from former underground storage tanks at CAS 23-02-08 contains TPH-diesel-range organics (DRO) above the PAL of 100 milligrams per kilogram, confined vertically from a depth of approximately 400 feet (ft) below ground surface (bgs). The contamination is confined to 12.5 ft bgs to the subsurface media and laterally within approximately 100 ft of the release. (2) A single soil sample collected from the depth of 99 to 100 ft bgs demonstrated the presence of TCE at a concentration above the PAL. (3) Two soil samples collected from depths of 198 to 199 ft bgs and 380 to 382 ft bgs demonstrated the presence of benzo(a)pyrene at a concentration above the PAL. (4) Two soil samples collected from depths of 240 to 241 ft bgs and 290 to 291 ft bgs demonstrated the presence of dibenz(a, h)anthracene at a concentration above the PAL. Tier 2 final action levels (FALs) were then calculated for these contaminants. The Tier 2 FALs for TCE, benzo(a)pyrene, and dibenz(a, h)anthracene were calculated based on a limited exposure to subsurface contamination scenario, and the Tier 2 FAL for TPH-DRO was established as the U.S. Environmental Protection Agency Region 9 Preliminary Remediation Goal values for the individual hazardous constituents of diesel. The evaluation of TPH-DRO, benzo(a)pyrene, dibenz(a, h)anthracene, and TCE based on the Tier 2 FALs determined that no FALs were exceeded. Therefore, the DQO data needs were met, and it was determined that no corrective action (based on risk to human receptors) is necessary for the site.

Book excerpt: Corrective Action Unit (CAU) 425 is located on the Tonopah Test Range, approximately 386 kilometers (240 miles) northwest of Las Vegas, Nevada. CAU 425 is listed in the Federal Facility Agreement and Consent Order (FFACO, 1996) and is comprised of one Corrective Action Site (CAS). CAS 09-08-001-TA09 consisted of a large pile of concrete rubble from the original Hard Target and construction debris associated with the Tornado Rocket Sled Tests. CAU 425 was closed in accordance with the FFACO and the Nevada Division of Environmental Protection-approved Streamlined Approach for Environmental Restoration Plan for CAU 425: Area 9 Main Lake Construction Debris Disposal Area, Tonopah Test Range, Nevada (U.S. Department of Energy, Nevada Operations Office, 2002). CAU 425 was closed by implementing the following corrective actions: The approved corrective action for this unit was clean closure. Closure activities included: (1) Removal of all the debris from the site. (2) Weighing each load of debris leaving the job site. (3) Transporting the debris to the U.S. Air Force Construction Landfill for disposal. (4) Placing the radioactive material in a U.S. Department of Transportation approved container for proper transport and disposal. (5) Transporting the radioactive material to the Nevada Test Site for disposal. (6) Regrading the job site to its approximate original contours/elevation.

Book excerpt: This Closure Report (CR) has been prepared for Corrective Action Unit (CAU) 356, Mud Pits and Disposal Sites, in accordance with the Federal Facility Agreement and Consent Order. This CAU is located in Areas 3 and 20 of the Nevada Test Site (NTS) approximately 65 miles northwest of Las Vegas, Nevada. Corrective Action Unit 356 consists of seven Corrective Action Sites (CASs): 03-04-01, Area 3 Change House Septic System; 03-09-01, Mud Pit Spill Over; 03-09-03, Mud Pit; 03-09-04, Mud Pit; 03-09-05, Mud Pit; 20-16-01, Landfill; and 20-22-21, Drums. This CR identifies and rationalizes the U.S. Department of Energy (DOE), National Nuclear Security Administration Nevada Operations Office's (NNSA/NV's) recommendation that no further corrective action and closure in place is deemed necessary for CAU 356. This recommendation is based on the results of field investigation/closure activities conducted November 20, 2001, through January 3, 2002, and March 11 to 14, 2002. These activities were conducted in accordance with the Streamlined Approach for Environmental Restoration Plan (SAFER) for CAU 356. For CASs 03-09-01, 03-09-03, 20-16-01, and 22-20-21, analytes detected in soil during the corrective action investigation were evaluated against Preliminary Action Levels (PALs) and it was determined that no Contaminants of Concern (COCs) were present. Therefore, no further action is necessary for the soil at these CASs. For CASs 03-04-01, 03-09-04, and 03-09-05, analytes detected in soil during the corrective action investigation were evaluated against PALs and identifies total petroleum hydrocarbons (TPHs) and radionuclides (i.e., americium-241 and/or plutonium 239/240) as COCs. The nature, extent, and concentration of the TPH and radionuclide COCs were bounded by sampling and shown to be relatively immobile. Therefore, closure in place is recommended for these CASs in CAU 356. Further, use restrictions are not required at this CAU beyond the NTS use restrictions identified in the SAFER Plan. In addition, the septic tank associated with CAU 356 will be closed in accordance with applicable regulations.
