Planning Documents Known Releases SWMUs Tooele Army Depot Tooele, Utah. Volume 1: Corrective Measures Study Work Plan

摘要

This document is the Corrective Measures Study (CMS) Work Plan for the Known Releases Solid Waste Management Units (SWMUs) at Tooele Army Depot (TEAD; formerly the North Area), Tooele, Utah. The CMS Work Plan addresses seven of the nine SWMUs that were identified in the Phase II Resource Conservation and Recovery Act (RCRA) Facility Investigation (RFI) Report for the Known Releases SWMUs (Rust Environment & Infrastructure (E&I), 1995) as posing a potential risk to human health or the environment. The goal of the CMS Work Plan is to identify potential corrective measures alternatives for each of the SWMUs that were determined to pose a human health or environmental risk. (Note that the alternatives will be evaluated in the CMS Report, to be prepared upon completion of the CMS Work Plan.) The Work Plan accomplishes this goal by first identifying corrective action objectives (CAOs) for the COPCs. The development of CAOs considers land use and potential receptor assumptions, exposure pathways, results of the human health RA, health effects criteria, and background sample results. Both quantitative (surface soil) and qualitative (soil and groundwater) CAOs are identified to focus the development of treatment technologies on those that are capable of achieving the appropriate target levels. In addition, U.S. Environmental Protection Agency (EPA) guidance (Office of Solid Waste and Emergency Response (OSWER) Directive 9355.7-04) and U.S. Army policy (Radkiewicz, 1995) direct that CAOs should reflect the reasonably anticipated future land use to focus on developing practicable and cost-effective corrective measures alternatives and to streamline the environmental cleanup process.
