Dear Mr. Mackin:
The UST Limited Site Assessment received by the UST Section, Division of Waste
Management, Mooresville Regional Office on January 3, 2022 has been reviewed. The review
indicates that that soil contamination does not exceed the residential maximum soil contaminant
concentrations (MSCCs), established in Title 15A NCAC 2L .0411 and groundwater petroleum
contamination meets the cleanup requirements for a low -risk release under Title 15A NCAC
2L .0202 and .0400.
The UST Section determines the subject incident to be eligible conditionally for no further
action status. However, final approval is contingent on receipt of confirmation that public notice
requirements have been completed, as described in the following paragraph.
As soil contamination exceeds the lower of the soil -to -groundwater MSCCs, public notice in
accordance with 15A NCAC 2L .0409(b) is required. Thus, within 30 days of receipt of this letter, a

jurisdiction in which the contamination occurs, all property owners and occupants within or
contiguous to the area containing contamination, and all property owners and occupants within or
contiguous to the area where the contamination is expected to migrate. Within 60 days of receiving
