Risk-based Assessment and Corrective Action for
Petroleum Underground Storage Tanks

1900 North Main Street, Mount Holl
Gaston County
Incident Number: 91437
Risk Classification: Low

Dear Mr. Gilbert:
A review of information on file with the Underground Storage Tank (UST) Section, Division of Waste Management, Mooresville Regional Office indicates that soil and groundwater contamination meet the
cleanup requirements for a low-risk release under Title 15A NCAC 2L .0202 and .0400, but contamination
exceeds the limits allowed for the unrestricted use of a site where closed under risk-based cleanup standards.
The UST Section determines the subject incident to be eligible conditionally for no further action status.
However, final approval of no further action status is contingent on the filing of the approved Notice of Residual Petroleum (or NRP, see attached) with the Register of Deeds in the county in which the release is
located, verified by the receipt of a certified copy of the filed NRP by this office; and receipt of confirmation
that public notice requirements have been completed, as described below.
Be advised that, as contamination may exceed the groundwater quality standards established in Title 15A
NCAC 2L .0202, groundwater within the area where contamination is present or is expected to migrate is
not suitable for use as a water supply. Be advised that as soil contamination may exceed the residential
MSCCs, the property containing the soil contamination is suitable only for <Click and Select Soil NRP
Type, or blank/delete if GW only. >
As groundwater contamination may exceed the groundwater quality standards established in Title 15A
NCAC 2L .0202, and soil contamination may exceed the residential MSCCs, pursuant to NCGS 143B-
279.9 and 143B-279.11, you must file the approved Notice of Residual Petroleum (attached) with the
Register of Deeds in the county in which the release is located and submit a certified copy to the UST
Section within 30 days of receipt of this letter.
