Fiscal Year 2007 Phased Construction Completion Report for the Zone 2 Soils, Slabs, and Subsurface Structures at East Tennessee Technology Park, Oak Ridge, Tennessee
The purpose of this Phased Construction Completion Report (PCCR) is to present the fiscal year (FY) 2007 results of characterization activities and recommended remedial actions (RAs) for 11 exposure units (EUs) in Zone 2 (Z2-01, Z2-03, Z2-08, Z2-23, Z2-24, Z2-28, Z2-34, Z2-37, Z2-41, Z2-43, and Z2-44) at the East Tennessee Technology Park (ETTP), which is located in the northwest corner of the U.S. Department of Energy (DOE) Oak Ridge Reservation in Oak Ridge, Tennessee (Fig. 1). ETTP encompasses a total land area of approximately 5000 acres that has been subdivided into three zones--Zone 1 ({approx}1400 acres), Zone 2 ({approx}800 acres), and the Boundary Area ({approx}2800 acres). Zone 2, which encompasses the highly industrialized portion of ETTP shown in Fig. 1, consists of all formerly secured areas of the facility, including the large processing buildings and direct support facilities; experimental laboratories and chemical and materials handling facilities; materials storage and waste disposal facilities; secure document records libraries; and shipping and receiving warehouses. The Zone 2 Record of Decision for Soil, Buried Waste, and Subsurface Structure Actions in Zone 2, East Tennessee Technology Park, Oak Ridge, Tennessee (DOE 2005) (Zone 2 ROD) specifies the future end use for Zone 2 acreage as uncontrolled industrial for the upper 10 ft of soils. Characterization activities in these areas were conducted in compliance with the Zone 2 ROD and the Dynamic Verification Strategy (DVS) and data quality objectives (DQOs) presented in the Remedial Design Report/Remedial Action Work Plan for Zone 2 Soils, Slabs, and Subsurface Structures, East Tennessee Technology Park, Oak Ridge, Tennessee (DOE 2007) (Zone 2 RDR/RAWP). The purpose of this PCCR is to address the following: (1) Document DVS characterization results for the accessible EUs in FY 2007; (2) Describe and document the risk evaluation for each EU, and determine if the EU met the Zone 2 ROD requirements for unrestricted industrial use to 10 ft bgs; (3) Identify additional areas not defined in the Zone 2 ROD that require remediation based on the DVS evaluation results; and (4) Describe the RAs performed in Zone 2. The Zone 2 ROD divided the Zone 2 area into 7 geographic areas and 44 EUs. To facilitate the DQOs of the DVS process, the Zone 2 RDR/RAWP regrouped the 44 EUs into 12 DQO scoping EU groups. These groups facilitated the DQO process by placing similar facilities and their support facilities together and allowed identification of data gaps. The EU groups were no longer pertinent after DQO planning was completed, and characterization was conducted as areas became accessible. As the opportunity to complete characterization became available, the planned DVS program was executed and completed in FY 2007 for the 11 EUs addressed in this document. The main body of this report describes both the DVS process and scope of work performed and the RAs completed. The scope and approach for performing DVS activities performed in FY 2007 that lead to action/no further action decisions are presented in Sects. 2 through 4. RAs performed in FY 2007 are presented in Sects. 5 through 10. Future land use is described in Sect. 11, and the status of all Zone 2 EUs as of this PCCR is presented in Sect. 12.
