North Carolina Department of Environmental Quality—Division of Water Reso Q �
NOTIFICATION OF INTENT (NOI) TO CONSTRUCT OR OPERATE INJECTION WELLS
The following are"permitted by rule"and do not require an individual permit when constructed in accordance
with the rules of 15A NCAC 02C.0200(NOTE:This form must be received at least 24 DAYS prior to injection
AQUIFER TEST WELLS(15A NCAC 02C.0220)
These wells are used to inject uncontaminated fluid into an aquifer to determine aquifer hydraulic characteristics.
INSITU REMEDIATION(15A NCAC 02C.0225)or TRACER WELLS(15A NCAC 02C.0229):
1) Passive Injection Systems-In-well delivery systems to diffuse injectants into the subsurface. Examples include
ORC socks,iSOC systems,and other gas infusion methods(Note: Injection Event Records(IER)do not need to be
submitted for replacement of each sock used in ORC systems).
2) Small-Scale Injection Operations—Injection wells located within a land surface area not to exceed 10,000
square feet for the purpose of soil or groundwater remediation or tracer tests. An individual permit shall be required
for test or treatment areas exceeding 10,000 square feet.
3) Pilot Tests -Preliminary studies conducted for the purpose of evaluating the technical feasibility of a
remediation strategy in order to develop a full scale remediation plan for future implementation,and where the
surface area of the injection zone wells are located within an area that does not exceed five percent of the land
surface above the known extent of groundwater contamination. An individual permit shall be required to conduct
more than one pilot test on any separate groundwater contaminant plume.
4) Air Injection Wells-Used to inject ambient air to enhance in-situ treatment of soil or groundwater.
Print Clearly or Type Information. Illegible Submittals Will Be Returned As Incomplete.

RE: Site Acceptance/Access Request

Morganton,Burke County,North Carolina(ARO)
STF Incident#20326
Risk/Rank: Intermediate
Dear Property Owner:
The Asheville Regional Office(ARO)has referred the subject site to the State Underground Storage Tank
(UST)Trust Fund Branch,State-Lead Program for inclusion on the list of sites awaiting cleanup. In 1997,a
petroleum release was documented at the former Foothills Service Center during a Phase II Abandoned UST
Study of Burke County. As part of the Study, soil and groundwater samples were collected around the five
USTs and pump island. The assessment identified up to 7,300 mg/kg gasoline-range Total Petroleum
Hydrocarbons in the soil, and 19,000 ug/l benzene in the groundwater. A Responsible Parry has not been
identified. Based on the contamination remaining at the site,the referenced property is being accepted by the
State for inclusion to the list of sites awaiting State-Lead cleanup. According to the information on file,you are
not considered to be an owner or operator of the USTs when the releases occurred pursuant to G.S. 143-
215.94A.
At this time,the risk of this site is Intermediate,and we will begin our assessment when funding is available. We
would appreciate your cooperation, and request that you sign and return the attached Site Access Agreement
giving us and our contractors permission to go onto the property and conduct work.
Please note that failure to allow access to the property could potentially make you responsible for the cleanup
under other State and Federal regulations. If you have any questions,please contact Sharon Ghiold at(919)
707-8166 or sharon. old mcdenr.gov.
