DUE DILIGENCE FOR PROPERTY TRANSFER
As part of the due diligence process for the Memphis & Shelby County Port Commission considering purchase of an approximately 43-acre parcel from the United States Department of the Navy, Tioga Environmental Consultants performed an assessment encompassing various components of a Phase I Environmental Site Assessment, surficial soil sampling, groundwater and depth soil sampling, vapor sampling, and a hazardous material building survey.
Following the ASTM Standard for Phase I Environmental Site Assessments, Tioga researched the property and adjacent parcels’ history to identify any recognized environmental conditions.
The historical use of the property and adjacent parcel was industrial – manufacturing metal pressure vessels for the nuclear and process industries. Soils contaminated by lead, PCBs, and petroleum were identified when the Navy purchased the property in the early 1990s and the contaminated media was remediated to the satisfaction of the State of Tennessee. Because regulatory thresholds have changed over time and vapor was never assessed, Tioga obtained 23 surficial soil samples; two groundwater samples; two subsurface soil samples; and six vapor samples to ascertain any lingering effects from the Property’s prior use. Ultimately, no constituents were identified at a concentration providing need for further investigation.
Tioga staff surveyed the approximately 19,500 square foot building over the course of two days for lead and asbestos. 60 materials were sampled and four were identified as asbestos-containing materials. 192 painted surfaces were tested for lead-based paint at the property via Tioga’s X-Ray Fluorescence spectrum analyzer instrument and no components were identified as lead-containing. Tioga also provided an estimate of hazardous materials abatement and demolition costs to the client.
