ADDITIONAL REGIONAL STAFF REVIEW ITEMS
The Pre -Regulatory Landfill has been assigned 1NSB site # NONCD000807. The site is listed as a Superfund site.
There is observed C&D type material exposed in the wooded area of the property behind the parking lot. Also, there is documentation
of 55-gallon drums containing Lead and Chromium waste on the property. The Site Summary Report for July 21, 2021 prepared by
Schnabel Engineering South, P.C. of Greensboro N.C. IHSB DOC # SF_F NONCD0000807_07-21-2010_IHS_LR.
The information for the nearby sites indicates the former presence of several Gas Stations and Automotive Service facilities with
former USTs, several Former Dry Cleaning facilities, a Construction Company, and the Former Pre -regulatory Southside Ash
Landfill.
A review of the DWM Site Locator Web Browser Tool, indicates several potential sources of contaminates near and around the
subject site. A documents review revealed that an unknown quantity of Hazardous waste was stored within the former Industrial
Crankshaft & Engineering Co, Inc. facility d/b/a/ Dynatech Industries Site located at 2213 Toomey Ave., Charlotte. This facility is
listed as a Superfund/ Inactive Section facility within permit # NCD9811014517.
Assessment documents were reviewed associated with these former facilities. The documents include GW Chemistry data that was
available on the Division of Waste Management Site Locator Tool.
Many of these facilities have received NFA status from DWM for a variety of reasons.
GW analytical data from existing monitor wells indicate petroleum constituents present at levels above 2L or PSRG Soil Standards.
There are no water supply wells found to be located on the property.
