Page 2 of3 ENVIRONMENTAL REPORT SUPPLEMENT The following correspondence is provided to the NRC as a summary of events surrounding the discovery of a leaking pipe located underground and under the building at the Columbia Fuel Fabrication Facility (CFFF) in 2011. Included in the correspondence is: Petiinent background information, including underground piping construction and leak discovery; Subsequent actions taken to correct the leak and prevent recurrence; An evaluation of the environmental impact at the time; Plans for remediation until decommissioning; and A hydrology analysis performed by AECOM on the site's ability to detect any potential contaminant movement from the leak location under the building. Underground Piping Construction The Uranium Recycling and Recovery Services (URRS) area is located in the southwest p011ion of the facility. As pati of the I 978 expansion project to the West side of the manufacturing building, the Contaminated Waste Water (CWW) drainage line was installed. The contaminated waste water piping system was constructed of heavy cast iron piping. Leak Discovery In 2011, Westinghouse discovered a small void under the concrete floor slab while working in the vicinity of the buried piping system. Upon fmiher investigation it was discovered that the buried piping system running through the URRS area (in Solvent Extraction) had developed a leak. A patiial blockage was also identified in the system in the same timeframe. The building elevation in the Solvent Extraction Area is higher than the elevation of the outside roadway. One section ofthe piping that contained a leak (between column lines 2CC and 3CC) was located approximately 2 feet below the Solvent Extraction floor grade and approximately 2.5 feet above the outside, finished road grade. The leaking section of the pipe where boring samples were collected (between column lines 5CC and 6CC) had invert elevations ranging from approximately 3 feet to 9 feet below the Solvent Extraction finish floor grade and between one foot above to 4.5 feet below the outside finished road grade. Groundwater sampling well W-38 is installed flush with the outside finished grade. Corrective and Preventive Actions The first action taken was to remove the blockage in the leaking CWW line to fully restore its flow path and minimize any further flow out the breach. A review of the existing inputs to the CWW drainage line revealed condensate drains from air conditioning units, eyewash and water fountain drains, chemical maintenance area service and lavatory sinks, and ventilation housing drains. (Note: All ventilation housing drains normally have zero flow. There must be an upset in the system or equipment failure to produce any flow.) Fwiher investigation determined that the piping had most likely deteriorated from the past practice of routing a mixture of hot steam condensate and caustic solutions through this line. It was then confirmed that contaminated, acidic, and/or caustic solutions are no longer routed to this line. Upon continued investigation with a piping camera system, a second breach in the system was identified fmiher down the piping. Upon discovery of the second breach, Westinghouse employed the services of a ground penetrating radar company to evaluate the condition of the subsurface area beneath the concrete floor slab within the areas of the piping breaches. The ground penetrating radar identified a larger void beneath the concrete floor slab within the areas of the piping breaches. Westinghouse determined the most appropriate long term action to prevent recurrence was to install a new above ground piping system for the contaminated waste water drainage in the solvent extraction area and the chemical maintenance area. Environmental Impact The next course of action was to determine whether contaminated effluents had been released to the subsurface soil beneath the piping system. To gain access to the soil below for sampling purposes, Westinghouse performed core boring in four strategic locations through the existing concrete floor slab. Soil, sludge, and water samples were collected from these locations and sent off for analysis (Attachment I: GEL

Page 3 of3 Work Order 297573). The soil borings indicated that the radar study had misidentified a larger void than was actually present, since some of the expected void area was actually filled with a different density of soil. Nonetheless, the sampling results indicated elevated levels of U-234, U-235, and U-238 in the soil, sludge, and water as shown below in Table 1. Because the leak location was under the building's concrete slab in an existing chemical process area, the discovery and subsequent investigative work was recorded in the Columbia Fuel Fabrication Facility Decommissioning Funding Plan.

374.4 pCi/g 405.1 pCi/g 98,120 pCi/g Based on current knowledge, at the time of decommissioning, the concrete floor slab will be saw cut around the perimeter of the area of concern. Since the area of concern is within the larger boundary of the Solvent Extraction process area, the entire footprint of solvent extraction (i.e. 8,160 ft2) will be removed down to a depth of approximately ten feet below land surface (bls). The cooling water generated during the saw cutting will be collected, sampled, and processed, if necessary, with all other liquids collected during the soil remediation. The concrete floor slab will be removed and packaged for final disposition. It is estimated that eighty one thousand six hundred ten (81,61 0) cubic feet of soil will be removed, packaged and stored on site until all soil has been remediated and final shipments are arranged. Site Hydrogeology Assessment of groundwater at CFFF began in 1989 and is on-going. During previous investigations, aquifer characteristics such as groundwater flow direction and velocity at CFFF were assessed. Based upon data collected during the site investigations, groundwater beneath the CFFF flows to the southwest at a velocity of approximately 153 feet/year. These assessments also provided an understanding of the site geology and resulted in an extensive monitoring well network. The water table aquifer generally consists of loose sand and silty sand underlain by a clay confining unit with a thickness ranging from 39 to 83 feet. This confining unit drastically impedes the vertical migration (ve1tical hydraulic conductivities of less than 1 x 10-7 em/sec, S&ME 1982) of groundwater. Currently there are 35 monitoring wells in the water table aquifer and three wells in the Black Mingo aquifer beneath the confining unit. Monitoring well W-37 was installed in 1992 adjacent to the URRS Solvent Extraction area as pa1t of an investigation for gross alpha in soil and gross alpha/gross beta in groundwater. The investigation recommended the installation of well W-38, which was later performed. Monitoring well W-38 is located approximately 60 feet southwest of the western edge of the URRS. Based upon data collected from these two monitoring wells, the depth to groundwater in the vicinity of the URRS area has historically fluctuated from approximately 9 to 16 feet bls. Monitoring wells W-37 and W-38 are screened from 15.5 to 20.5 and 15 to 20 feet bls, respectively, and the confining unit is approximately 28 feet bls near the URRS. These monitoring wells are likely positioned to monitor for potential groundwater impacts from URRS, including the 2011 piping leak under the Solvent Extraction area. Additional monitoring wells within the CFFF's well network are also located downgradient of monitoring well W-38. Detailed site geology and hydrogeology information can be found in AECOM's December 31, 2013 Remedial Investigation Rep01t. is the consolidated monitoring history since 2004 for W-28, W-29, W-30, W-35, W-37, W-38, and W-45.
