Former Hospital Property

VOLUNTARY CLEANUP, OVERSIGHT & ASSISTANCE PROGRAM ASSESSMENT

In November, 2016, Tioga conducted a Phase II Environmental Site Assessment at a former hospital in Memphis, TN. As part of the Phase II soil samples were collected at the site. Analytical results identified concentrations of polycyclic aromatic hydrocarbons at the site above EPA regional screening levels. Per Tioga’s recommendations in the Phase II, additional surficial soil sampling was conducted at the Property. Analytical results from the surficial soil analysis identified additional areas of concern at the property. Upon the recommendation of Tioga, the property was entered into the Tennessee Department of Environment and Conservation (TDEC) Voluntary Cleanup, Oversight, and Assistance Program (VOAP).

After entrance of the property into the VOAP, Tioga corresponded with TDEC to determine the need for additional assessment. The Phase II and Additional Surficial Soil Assessment reports written by Tioga were submitted to TDEC and it was determined that previous environmental assessments were sufficient and no further soil or groundwater assessment was required at the property but a sub-slab vapor assessment would be necessary. 

 At the request of TDEC, Tioga drafted a workplan detailing the installation and sampling of fifteen temporary sub-slab vapor monitoring points. Upon TDEC approval of the workplan, on June 7 and 8, 2017, Tioga personnel installed 15 sub-slab vapor monitoring points and collected samples at the property. Vapor samples were submitted for laboratory analysis of volatile organic constituents. 

Tioga prepared a Sub-Slab Vapor Assessment Report for TDEC detailing the field work conducted at the property and interpreting analytical results. Based on the analytical results, it was the recommendation of Tioga that no risk from intrusion of sub-slab vapor was present at the property and no further assessment was required. TDEC agreed with Tioga and issued a letter requesting no further assessment on July 24, 2017.
