1.0 INTRODUCTION
Cabrera Services, Inc. (CABRERA) mobilized personnel to the United Nuclear Corporation (UNC) site located at 71 Shelton Avenue, New Haven, Connecticut from 29Mar10 to 01Apr10 for the purpose of collecting soil and sediment samples in order to (1) confirm asbestos covered piping in the South Trench; (2) characterize sediment in the Argyle Street/Shelton Avenue sewer; and (3) profile waste material that will be generated as a part of the site remediation at the proposed excavation area at the Decon Pit, the proposed excavation area at the X-Ray Read Room, and debris in the South Trench. A secondary sampling objective was to evaluate the uranium isotopic ratio consistency for use as a quick turn around time field Derived Concentration Guideline Level (DCGL) measurement during remediation.
Characterization samples were collected from each of the four areas in order to obtain results representative of the waste that is expected to be generated during remediation. The samples were packaged in accordance with applicable State and Federal regulations and submitted to GEL Laboratories, LLC for analysis. The analytical suite performed was based on information obtained from previous sampling events, site process knowledge, and waste acceptance criteria (WAC) requirements for the Energy Solutions Low Level Waste (LLW) disposal facility at Clive, Utah. Analyses included Resource Conservation and Recovery Act (RCRA) metals, volatile organic compounds (VOCs),
semi-volatile organic compounds (SVOCs),
Pesticides/Herbicides, Reactive Sulfides, Reactive Cyanides, pH, and Isotopic Uranium by alpha spectroscopy. In addition, bulk asbestos analysis was performed on piping insulation samples obtained from the South Trench to determine the presence of Asbestos-Containing material (ACM).
The sampling strategy for each area, analytical results, and implications for site remediation are presented below. All figures referenced in this Sampling Report are contained in Appendix A.
Tables 1 through 4 present positive data (i.e., detected concentrations) that were reported for each area as compared to the RCRA Toxicity Characteristic Leaching Procedure (TCLP) limits used to determine hazardous waste (40 Code of Federal Regulations [CFR] 261.24). The complete analytical data packages are included in Appendix B, along with summary data tables for each area.
UNC New Haven Sampling Report FINAL Former UNC Manufacturing Facility CABRERA SERVICES INC 2-1 2.0 CHARACTERIZATION AREAS 2.1 X-Ray Read Room Results from previous investigations were used to define a proposed excavation area at the X-Ray Read Room, as shown on Figure 1. The concrete floor was removed from the excavation area and the concrete rubble was surveyed for radiological release and will be disposed offsite at a local landfill after remobilization for remediation. A mini excavator was used to create a small test pit at each sample location to a depth consistent with the reported depth of contamination from previous investigations. Sample UNC-WC-XY-001 was obtained by taking an aliquot of soil from one of each of the three test pit locations (4 feet in depth) as shown in Figure 1.
Sample UNC-WC-XY-002 was collected at a depth of 9 feet from the test pit location at the northern portion of the X Ray Read Room, as shown in Figure 1. Table 1 presents a summary of the positive data that were reported for this area.

The concrete floor was removed from the excavation area and will be disposed offsite at a local landfill after remobilization for remediation. A mini excavator was used to create a small test pit at each sample location to a depth consistent with the reported depth of contamination from previous investigations. Sample UNC-WC-DR-001 was obtained by taking an aliquot of soil from one of each of the two test pit locations (3 feet in depth) as shown in Figure 3.

UNC New Haven Sampling Report FINAL Former UNC Manufacturing Facility CABRERA SERVICES INC 3-1 3.0 SAMPLING RESULTS 3.1 RCRA Metals With the exception of sample UNC-WC-TR-002 from the South Trench, none of the metals results exceeded the RCRA hazardous waste limits for toxicity. The results of the lead analysis for sample UNC-WC-TR-002 exceeds the toxicity limit of 40 CFR 261.24 and would therefore be classified as a D008 characteristic hazardous waste. If the material is assigned a waste code it must also be evaluated for underlying hazardous constituents (UHCs). It is of note that the cadmium results from UNC-WC-TR-001 exceeds the treatment standards of 40 CFR 268.40 and would be considered an UHC if the material were designated as a D008 waste. Based on these sample results some portion of the waste generated in the vicinity of these samples will likely be a radioactive and RCRA mixed waste and may require that cadmium be reported as a UHC.
3.2 Organics Samples from the X Ray Read Room (UNC-WC-XY-001) and the Former Decon Pit (UNC-WC-DR-001) contained positive results for the VOC constituents trichloroethylene and tetrachlorethylene. However, as shown in Tables 1 and 4, none of the detected concentrations exceeded the RCRA hazardous waste limits for toxicity.
3.3 Hazardous Characteristics All soil and sediment samples were analyzed for chemical properties to determine the presence of the following RCRA hazardous characteristics:
- Ignitable -flashpoint <140º F
- Corrosive - Aqueous solutions of pH 2 or 12.5
- Reactive - Normally unstable or explosive, reacts violently with water, or may release a toxic gas on contact with water (e.g., certain cyanide or sulfide-containing compounds)
As shown in the data summary tables presented in Appendix B, none of the samples exhibited the hazardous characteristics listed above. Flashpoints were reported as non-detect (detection limit of 75 º F) for all samples; corrosivity values ranged from 6.8 to 9.2; and reactive releasable cyanide and sulfide results were less than the regulatory limits of 250 milligrams (mg) per kilogram (kg) and 500 (mg)/kg, respectively.
UNC New Haven Sampling Report FINAL Former UNC Manufacturing Facility CABRERA SERVICES INC 3-2 Samples were also analyzed for the presence of free liquids in accordance with 40 CFR 264.314 and 265.314. All results were reported as non-detect.
The RCRA hazardous characteristic of toxicity is discussed in the above sections for metals and organics and presented in Table 1 through 4.
3.4 Uranium While the waste is considered Low Level radioactive Waste (LLRW), analytical results confirm that the waste includes radionuclides that are considered special nuclear material (SNM). The U.S. Nuclear Regulatory Commission (NRC) defines SNM as:
(1) Plutonium, Uranium-233, Uranium enriched in the isotope 233 or in the isotope 235, and any other material which the Commission, pursuant to the provisions of section 51 of the act, determines to be special nuclear material, but does not include source material; or (2) any material artificially enriched by any of the foregoing but does not include source material.
As such, the appropriate waste certificates required by Energy Solutions will be submitted with each shipment.
3.5 Asbestos As detailed in the ChemScope inspection and data report (Appendix C), ACM was detected in each of the three piping insulation samples. Materials which contain greater than 1% asbestos by polarizing light microscopy (PLM) analysis are considered to be ACM under Environmental Protection Agency (EPA) and the State of Connecticut regulations. The inspection indicated that there are three pipe runs that contain ACM pipe insulation. Sample analysis indicated that the pipe insulation contained between 1% and 75% asbestos. The inspection also estimated approximately 2,400 lineal feet of 8 inch and 4 inch ACM covered piping.
UNC New Haven Sampling Report FINAL Former UNC Manufacturing Facility CABRERA SERVICES INC 4-1 4.0 QA/QC RESULTS A verification of the analytical data quality was performed and is documented in Appendix D.
Data completeness, general quality assurance, and usability were evaluated and potential data integrity concerns were identified.
The only data quality issue noted is the secondary sampling objective for the uranium analyses and the usability as DCGL measurements during remediation. Initial analytical results reported total uranium in mass/mass units (i.e., micrograms per gram [µg/g]). The data validation report noted that isotopic uranium ratios are necessary, and all results should be reported as activity/mass (i.e., picocuries per gram [pCi/g], in order to be useful in DCGL comparisons to the site remediation goal of 30 pCi/g. In addition, radiological analyses (and associated QC analyses) did not meet the standard detection limits due to limited sample volume.
Based upon the data quality report recommendation and follow up discussions with the laboratory, sufficient aliquot will be used to assure a MDC of 0.5 pCi/g. Sample analysis will be limited to gamma spectroscopy. A corrected data package was received that reported isotopic uranium based upon alpha spectroscopy, and is included in the Appendix B dataset. The isotopic uranium data has been incorporated into Tables 1 through 4.

SUMMARY
AND IMPLICATIONS FOR DECOMMISSIONING Based on the waste characterization results, it is anticipated that some mixed waste (RCRA and LLRW) will be generated during remediation of the South Trench area. SNM will also require handling and disposal as a result of remediation activities.
In the approved Decontamination and Decommissioning Plan, the ratio correction factor to be applied is 27 (i.e. 27xU235 [pCi/g] to derive U234). This correction factor was based on historical information from the material processed/handled on site. The U235 activity will be determined via gamma spectroscopy. The QC MDC issues noted in Section 4 will be resolved by ensuring a sufficient sample quantity and laboratory analysis method during remediation.
Based on this analysis, the application of this conservative approach coupled with the use of the In Situ Object Counting System (ISOCS') will be effective for use in field-based decision making relative to remediation. It is recommended that periodic off-site gamma spectroscopy sample analyses be conducted to provide supplemental data to demonstrate that the approach is maintaining functionality. Larger aliquot size and increased homogenization in the field prior to lab submittal is also recommended to enhance data quality.
The planned decommissioning activities will be influenced by the waste types defined by the Department of Energy disposal contract with EnergySolutions. Soil-like and debris-like waste types are expected with an assumed preference to ship as much of the waste volume as soil-like as possible to avoid the higher disposal cost of debris. The percent debris and the percent moisture limitations in the soil-like waste type will be critical to minimize debris cost surcharges.
On site management of debris, especially oversized debris as defined by EnergySolutions is uncertain. The presence of subsurface equipment footers inside the building, the manhole structures associated with the Argyle Street Sewer removal, and disposal of piping from the South Trench are all potential oversized debris waste issues. The ability to decontaminate and radiologically release these large concrete features is uncertain. The void space in the piping is defined by EnergySolutions as oversized debris unless the void space is filled or the piping can be crushed or the pipe cut in half (length wise) to eliminate the void space. Debris sizing is another option for concrete rubble provided that the cost to size the material is cost effective.
UNC New Haven Sampling Report FINAL Former UNC Manufacturing Facility CABRERA SERVICES INC 5-2 A drying agent will be added to waste packages to prevent the formation of free liquids during transport to the disposal facility. The moisture content limits of the DOE disposal contract may require further application of drying agents to lower the moisture content of the waste. Wastes with high moisture contents will include the South Trench debris from wet decontamination and the Argyle Street Sewer if weather conditions are wetter than usual. To the extent practical, wetter waste will be blended with dryer waste of the same waste type to manage moisture.
The amount of mixed waste identified in the South Trench appears to be limited and additional sampling of the South Trench waste during remediation to segregate mixed waste from LLRW will further minimize the volume of mixed waste.
As a cost savings effort, the ACM abatement activities associated with the South Trench decontamination can be limited to abatement of only the ACM needed to complete the Final Status Survey. This limited abatement will result in a cost savings due to the shortened duration of the abatement activities and a reduction of the ACM volume. ACM abatement will be accomplished by removing debris/ACM from the bottom of the South Trench. The FSS will be accomplished as described in the Final Status Survey Plan. Following confirmation of a successful final status survey, the surface of the South Trench will be sprayed with a lock down product to obtain 3rd party air monitoring clearance and allow removal of the air containment controls. This cost savings is contingent upon Oak Ridge Institute for Science and Education (ORISE) being able to enter an ACM abatement enclosure to perform their Quality Assurance (QA) function.
