Mid-Atlantic managed environmental activities for the redevelopment of the North Hills Mall. Activities included the cleanup of gasoline contamination from the North Hills Exxon Station leaking underground storage tank (LUST) site, the implementation of a Brownfields Agreement for non-UST contamination, and other environmental issues associated with the demolition and renovation of the mall property. For the North Hills Exxon Station, Mid-Atlantic successfully implemented an aggressive cleanup program approach to finish Comprehensive Site Assessment, Corrective Action Plan, and remediation system design and installation within a 1.5 year period of assuming project responsibilities. A 129 well remediation system was installed and removed approximately 2,000 gallons of gasoline from the subsurface over a six-month period. An environmental investigation was also conducted for an area of non-petroleum soil and groundwater contamination to support the development of a Brownfields Agreement with DENR.
