An Environmental Easement for the property was filed on July 31, 2006, restricting future use to industrial/commercial, and requiring: 1) monitoring and maintenence of the subsurface barrier, 2) continuous operation of a sub-level ventilation system 3) annual certification.

Institutional controls required by the environmental easement were certified February 9, 2007. Annual certification of institutional and engineering controls was provided on March 25, 2008 and approved on April 25th.

Site Environmental Assessment
The site was significantly contaminated with MGP wastes and petroleum. The RAWP required excavation of the site to depths of 15 to 18 feet across the site to accommodate the construction of a new office building with subsurface parking. Subsurface barriers and an active ventilation system were also components of the site remedy. Construction activities started in summer 2004 and were official completed with the approval of the Final Engineering Report on August 31, 2006.

Site Health Assessment
On-site soils and groundwater are contaminated with petroleum-related contaminants. The site is paved; therefore, direct contact exposure is not expected. The area is served with public water; therefore, ingestion exposure is not expected. Assessment of the potential for inhalation exposures via vapor intrusion will be conducted during the remedial investigation.
