MD&E is leading the closure of a 100-year old decommissioned manufacturing facility in northwestern Ohio for a multi-national chemical company. The effort has entailed the detailed characterization of a facility that performed heat treatment of metal components for the automobile industry over much of its history. Currently, work performed by MD&E is focused on the removal and characterization of environmental impacts associated with a subgrade cistern that was used to store sodium cyanide solutions used in the thermal treatment processes. MD&E is directly responsible for coordinating the planning and execution of these activities with the Ohio EPA.
