VERTEX was retained to assist in the acquisition of approximately 253-acres of predominantly agricultural land in Aurora, Colorado. Although primarily agricultural land, an 18-acre portion of the site was historically used as a joint venture research and development facility between the U.S. Department of Transportation and an elevator company between the early 1970s until the late 1980s.
The project included the completion of an ASTM Phase I Environmental Site Assessment (ESA) of the property by VERTEX, which revealed several Recognized Environmental Conditions (RECs) including the historical research and development activities and a large quantity of various fly-dumped hazardous materials (i.e., paints, solvents, petroleum products), building materials and suspect asbestos-containing materials (ACMs).
VERTEX conducted a Phase II Limited Subsurface Investigation (LSI) at the facility that included the installation of soil borings and groundwater monitoring wells to assess for potential residual impacts from historical site operations. Although no subsurface impacts were found that exceeded Colorado state regulations, the quantity of hazardous materials dumped on-site necessitated the characterization and disposal prior to acquisition.
VERTEX conducted a Hazardous Material Survey that include sampling of suspect ACMs dumped on-site along with characterization and quantifying hazardous materials present for disposal requirements. No ACMs were found to be present in the fly-dumped materials.
VERTEX oversaw and managed the hazardous waste removal from the site which included disposal of approximately 60 cubic yards of illegally dumped regulated/hazardous materials and building debris for off-site recycling/disposal.
The project was completed on an expedited time schedule and under budget. VERTEX’s findings throughout the project provided the client with the ability to negotiate a better purchase price for the site and the peace-of-mind knowing they were purchasing an unimpacted site.
