This document provides guidance to personnel e.g., planners, cost estimators, specification writers, engineers, managers, and dredging contractors involved in dredging projects with sediment containing Munitions and Explosives of Concern MEC. The guidance is primarily in the form of compiled information gained from experiences on past dredging projects involving MEC and was compiled from a variety of sources. This report describes the different types of dredges and dredging projects that can encounter MEC, describes how these dredges operational methodologies can be impacted by MEC, and summarizes past project methodology modifications that have been used to deal with MEC. Technical aspects of past MECdredging projects are presented with regard to engineering controls to mitigate detonation hazards, underwater MEC detection and discrimination technologies, contracting, public awareness, safety requirements, and MEC separation techniques and where available subsequent impacts on production rates and costs.
