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 14 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.
IN SITU 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 is 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.
5) In -Situ Thermal Wells (IST) — Used to `heat' contaminated groundwater to enhance remediation.
Print Clearly or Type Information. Illegible Submittals Will Be Returned as Incomplete.

Deemed Permitted GW Remediation NOI Rev. 2-17-2020 Page 2
H. INJECTION ZONE MAPS — Attach the following to the notification.
(1) Contaminant plume map(s) with isoconcentration lines that show the horizontal extent of the
contaminant plume in soil and groundwater, existing and proposed monitoring wells, and existing and
proposed injection wells; and

DESCRIPTION OF PROPOSED INJECTION ACTIVITIES AT THE SITE — Provide a brief narrative
regarding the cause of the contamination, and purpose, scope, goals of the proposed injection activity:
Air Sparging (using air compressor) connected to TW-1 during 96-hour Mobile -Multiphase Extraction Event
(MMPE) wells MW-2, MW-6, MW-7, MW-8, MW-10, MW15, MW-17, MW-18 and MW-20 will be used as

K. INJECTION SUMMARY
NOTE: Only injectants approved by the epidemiology section of the NC Division of Public Health, Department
of Health and Human Services can be injected. Approved injectants can be found online at
http: //deq. nc. gov/about/divisions/water-resources/water-resources-permits/wastewater-branch/ground-water-
protection/ground-water-approved-injectants. All other substances must be reviewed by the DHHSprior to use.
Contact the UIC Program for more info if you wish to get approval for a different additive. However, please
note it may take 3 months or longer. If no injectants are to be used use N/A.
