with the rules of 15A NCAC 02C .0200 (NOTE: This form must be received at least 14 DAYS prior to injection)
AQUIFER TEST WELLS U SA NCAC 02c .0220}
These wells are used to inject uncontaminated fluid into an aquifer to determine aquifer hydraulic characteristics.
IN SITU REMEDIATION O SA NCAC 02c .0225) or TRACER WELLS U SA 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.

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
(2) Cross-section(s) to the known or projected depth of contamination that show the horizontal and vertical

and proposed wells.
Deemed Pennitted GW Remediation NOI Rev. 3-21-2018 ~age 2
I. DESCRIPTION OF PROPOSED INJECTION ACTMTIES -Provide a brief narrative regarding the
purpose, scope, and goals of the proposed injection activity. This should include the rate, volume, and duration
of injection over time.
The proposed activities include the continuous injection of potable water into the six (6) existing infiltration
gallery injection points located in the former waste burial area. The infiltration gallery is composed of three
different zones, approximate I y 2,200 square feet each in size. The zones are approximate! y 13 feet below ground
surface and separated by 18-inch-high clay berms with 18 inches of stone in the base. Two north-south oriented
horizontal sections of slotted 4-inch PVC pipe are located in each of the zones and are vertically connected to
the ground surface by 4-inch PVC pipes. Potable water will be continuously gravity injected into each of the
points at approximately 0.5 gallons per minute (gpm) to promote capture and treatment of target volatile organic
compounds (VOCs) via the existing downgradient site groundwater extraction and treatment system.
J. APPROVED INJECTANTS-Provide a MSDS for each injectant (attach additional sheets if necessary).
NOTE: Only injectants approved by the NC Division of Public Health, Department of Health and Human
Services can be injected. Approved injectants can be found online at hup://deg.nc.eov/about/divisions/water-
resourccs/watcr -rcsourccs -pcrmits/wastcwatcr-branch/ground -watcr-protcction/!ITound -water-approved-injectants .
All other substances must be reviewed by the DHHS prior to use. Contact the UJC Program for more info (919-
807-6496).

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 (1 5A NCAC 02C .0220)
These wells are used to inject uncontaminated fluid into an aquifer to determine aquifer hydraulic characteristics.
IN SITU REMEDIATION O SA NCAC 02C .0225 ) or TRACER WELLS O SA 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 sha11 be reguired 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.

I. DESCRIPfION OF PROPOSED INJECTION ACTIVITIES -Provide a brief narrative regarding the
purpose, scope, and goals of the proposed injection activity. This should include the rate, volume, and duration
of injection over time.
The pro posed activities include the continuous injection of p otable water into the six (6) existing infiltration
gallery injection points located in the former waste burial area. The infiltration gallery is composed of three
different zones, a pproximately 2,200 s quare feet each in size. The zones are a pproximately 13 feet below eround
surface and sep arated by 18-inch-high clay berms with 18 inches of stone in the base. Two north-south oriented
horizontal sections of slotted 4-inch PVC pipe are located in each of the zones and are vertically connected to
the ground surface b v 4-inch PVC pip es. Potable water will be continuously gravity injected into each of the
points at a pproximately 0.5 gallons per minute (gpm ) to promote capture and treatment of target volatile organic
compounds {VOCs) via the existing downgradient site groundwater extraction and treatment s y stem.
J. APPROVED INJECTANTS-Provide a MSDS for each injectant (attach additional sheets if necessary).

(b) Depth below land surface of casing, each grout type and depth, screen, and sand pack
( c) Well contractor name and certification number
Deemed Permitted GW Remediation NOi Rev . 3-21-2018 Page 3
L. SCHEDULES — Briefly describe the schedule for well construction and injection activities.
Potable water injections into the infiltration gallery will commence upon approval of this permit.
M. MONITORING PLAN — Describe below or in separate attachment a monitoring plan to be used to determine
if violations of groundwater quality standards specified in . uhrchal±ler n21. result from the injection activity.
Monthly groundwater level measurements will be collected for six months post injection. Water level collection
will then be collected on an annual basis after six months. Groundwater samples will continue to be collected
on an annual basis.
