Multiuser Disposal Sites (MUDS) for Contaminated Sediments from Puget Sound-Subaqueous Capping and Confined Disposal Alternatives
Abstract
The U.S. Army Engineer District, Seattle (CENWS), is participating in the Puget Sound Confined Disposal Site Study. This study is aimed at determining the feasibility of establishing a system of multiuser disposal sites (MUDS) for disposal of contaminated sediments dredged from Puget Sound. Most of the contaminated sediments within Puget Sound are located within the central portion of the sound and are associated with environmental cleanup projects directed through Federal or state enforcement actions, projects with restoration of aquatic habitat as their primary purpose, and dredging of Federal and non-Federal navigation channels. The feasibility evaluation will be conducted in phases. The initial programmatic phase resulted in a programmatic Environmental Impact Statement (PEIS). Site-specific evaluations along with a site-specific PElS will be conducted in subsequent phases. Disposal alternatives that will be evaluated include: (a) level bottom capping and contained aquatic disposal (CAD), (b) nearshore (or island) confined disposal facilities (CDFs), (c) upland (CDF) disposal, (d) disposal in solid waste landfills, and (e) multiuser access to larger fill projects. CENWS requested support from the U.S. Army Corps of Engineers Engineer Research and Development Center (ERDC), Environmental Laboratory, Vicksburg, MS, in conducting the feasibility evaluations. This report describes various subaqueous capping and confined (diked) disposal alternatives and provides conceptual designs and design and performance standards for these alternatives.
