NC Department of Environmental Quality-Division of Water Resources (DWR)
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 in jection )
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 (ISA NCAC 02C .0229):
1) Passive Injection S vstems -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 In jection O perations -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 In jection 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
(2) Cross-section(s) to the known or projected depth of contamination that show the horizontal and vertical
extent of the contaminant plume in soil and groundwater, changes in lithology, existing and proposed
monitoring wells, and existing and proposed injection wells.
(3) Potentiometric surface map(s) indicating the rate and direction of groundwater movement, plus existing
and proposed wells.
I. DESCRIPTION OF PROPOSED INJECTION ACTIVITIES AT THE SITE -Provide a brief narrative
regarding the cause of the contamination, and pwpose, scope, goals of the proposed injection activity:
FT007 is a former fire trainin g area where contaminated fuels . waste chemicals, and uncontaminated fuel were
burned. The former fire trainirnr area had an above-!!round storage tank (AST ) with a fuel line that ran to the
trainin l!. pit. Durin g fire training exercises , the pit was filled with water prior to addition of a pp roximatel y 500
gallons of fuel that would be i enited and extinguished. An undernround draina ge s ystem collected li quids and
drained them to an under gr ound oil/water se parator (OWS ). which then discharned to the sanitary sewers stem.
Ozone injection was historicall y compl eted at this site but has not reduced the contaminant concentration below
screenine levels. The ozone injection wells are no longer in use and will not be utilized in association with the
pro posed injections. The purp ose of the in jection activi ty is to accelerate site closure using potassium persulfate
injections. The in jectant material is Provect-OX2 which is an extended release source of potassium persulfate
plus a ferric iron activator. In jections will be com pleted in nine direct push borings (see attached Figure H.3 )
at hot s pots identified near performance wells MW-4 lR. MW-105R. and MW-106. The direct push borin e s will
be advanced to a predetermined de pth (see attached Table ) then retracted 3.5 feet to ex pose the injection interval.
Performance monitorin g will be initiated one month after the in jections and continue quarterly for one vear. If
needed a second injection event will be com pleted followin l.! the initial year of performance monitoring .
J. WELL CONSTRUCTION DATA
(1) No. of injection wells: ---~9 ___ Proposed __ ~O ___ Existing (provide NC Well
Construction Record (GW-1) for each well)
(2) Appx. injection depths (BLS ):-'s=e=e-=a=tt=ac=h=e=d-=T=a=b=le'---'1'-----------------------
(3) For Proposed wells or Existing wells not having GW-ls, provide well construction details for each
injection well in a diagram or table format. A single diagram or line in a table can be used for
multiple wells with the same construction details. Well construction details shall include the
following (indicate if construction is proposed or as-built):
(a) Well type as permanent, Geoprobe/DPT, or subsurface distribution infiltration gallery
(b) Depth below land surface of casing, each grout type and depth, screen, and sand pack
(c) Well contractor name and certification number-Redox-tech-Kyle Baseley,

L. MONITORING PLAN -Describe below or in separate attachment a monitoring plan to be used to determine
if violations of groundwater quality standards specified in Subchapter 02L result from the injection activity.
Performance monitorim.!. will be completed quarterly starting one month after the completion of in jections to
allow the sodium persulfate to dissi pate. Durin!! the first round of sam pling, prior to purging, field testin g for
sodium persulfate will be conducted. If any persulfate is detected in uroundwater during this test, field parameters
will not be measured. When uroundwater is sam pled with persulfate present it interferes with water quali tv
probes and gi ves false readings. Groundwater sam ples will be anal vzed for VOCs and metals for four quarters.
Monitoring data will be utilized to determine if additional injections are re quired.

2. The cross section is from the Construction Completion Report for Ozone
Injection Remedial Action dated March 2017.
3. The potentiometric surface map and injection areas around monitoring
wells MW-41, MW-105R, and MW-106 are shown on this figure.
Historical contaminant plumes are shown due to the fact that current
concentrations at MW-41R do not exceed screening levels but historical
concentrations do exceed screening levels.
I. No change.
J. Existing ozone injection wells will not be utilized. Therefore, no construction
records for these wells are included. Direct push injection methods will be utilized.
Therefore, no construction records or well information are included. The depth of
