Brownfields are vacant or under utilized commercial and industrial sites, typically where contamination or perceived contamination inhibits the sale or redevelopment of the property. The federal government and various state agencies have implemented programs designed to encourage the redevelopment of Brownfields sites.

In Maryland, this process is implemented by the Voluntary Cleanup Program (VCP), which is administered by the Maryland Department of the Environment (MDE). Typically, using a Phase I Environmental Site Assessment (ESA), a Phase II ESA, and various supplemental data, the MDE can determine that either (a) the site does not warrant further evaluation or remediation and redevelopment can proceed, or (b) remedial action is necessary. When remedial action is needed, the cleanup criteria will be reflective of the future use of the property.

GTA can escort clients through the VCP process, including:

• Feasibility and Phase I ESA
• VCP application
• Phase II ESA and subsequent sampling/analysis procedures
• MDE discussion and negotiation process
• Preparation and execution of a Remedial Action Plan (RAP), if necessary
• Request for a "No Further Requirements Determination" or a "Certificate of Completion"
