FEATURED PROJECT:
Redevelopment of Chesapeake Paperboard
Baltimore, Maryland

Arc Environmental prepared and submitted an application for the former Chesapeake Paperboard Company Property for Maryland's Voluntary Cleanup Program in January 2006. To support the VCP application submittal, Arc updated the Phase I ESA for the Site and completed additional Phase II investigations .

Results of the these investigations identified concentrations of metals, volatile organic compounds, and semi-volatile organic compounds in surficial and subsurface soils and groundwater exceeding applicable State Cleanup Standards.

In addition, as part of the redevelopment of the Site, Arc Environmental performed facility decommissioning activities consisting of the indentification, removal, and disposal of hazardous and regulated substances, and closure of the existing storage tank systems (both aboveground and underground). Follow up activities, including a limited soil removal surrounding several of the former underground storage tank systems and removal of the subsurface lines associated with an aboveground storage tank system were also completed.

After review of the completed Voluntary Cleanup Program application, the Maryland Department of the Environment, requested the development of a Response Action Plan to address the soil impacts identified at the property.

A Response Action Plan was prepared for the property in August 2006 detailing, engineering and institutional controls consisting of a containment remedy (cap) and institutional controls to mitigate the identified risks to human health and the environment at the Site.

During the construction phase of the development, Arc Environmental continued negotiation with MDE to reduce the cap thicknesses in certain areas, and modify the capping protocol for electrical duct banks and utilities installed beneath building slabs. Arc Environmental also completed site monitoring during construction of the cap to ensure compliance with the Response Action Plan. The Site redevelopment is currently scheduled for late 2009/early 2010.
