Title: Response to comments and recommendations on RCRA Facility Investigation Plan for Group 4 at the Oak Ridge Y-12 Plant, Oak Ridge, Tennessee

Technical Report ·
OSTI ID:5824118

This document has been prepared to respond to comments and recommendations resulting from the Department of Energy (DOE) Technical Working Group Meeting-Y12 that was attended by representatives from the DOE Oak Ridge Field Office; Martin Marietta Energy Systems, Inc.; Environmental Protection Agency Region IV; and the Tennessee Department of Environment and Conservation. Comments and recommendations were provided to improve the sampling efforts proposed for the Abandoned Nitric Acid Pipeline (ANAPL) in the RCRA Facility Investigation Plan for Group 4 at the Oak Ridge Y-12 Plant, Oak Ridge, Tennessee (ES/ER-10/V1 D1 and ES/ER-10/V2 D1). Thus, the sampling methodology discussed in this document replaces the sampling approach discussed in Sect. 8.5 of that plan. The Nitric Acid Pipeline transported wastes from operations in Buildings 9215, 9212, and 9206 and discharged these wastes into the S-3 Ponds surface impoundments. Materials known to be discharged through the stainless steel pipeline included free nitric acid and depleted and enriched uranium. The revised sampling and analytical methodology for the ANAPL includes: Decreasing the number of soil sampling locations for this phase of the investigation; taking deeper samples from the proposed shallow soil sample sites and archiving all samples except the one taken nearest the pipeline; analyzing the sample taken nearest the pipeline for inductively coupled plasma metals, leachable nitrate, total uranium, and percent of {sup 235}U present; conducting field screening for volatile organic compounds; and proposing nitrate and uranium concentration action levels to trigger analysis of archived samples after analysis and evaluation of the samples taken nearest the pipeline.
