Central Office _;
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 .022 5> or TRACER WELLS (15A NCAC 02c .0229 ):
1) Passive Injection S stems -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 O p erations -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 (I ST )-Used to 'heat' contaminated groundwater to enhance remediation.
Print Clearly or Type Information. Illegible Suh11 flitals 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
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 purpose, scope, goals of the proposed injection activity:
OT021 is a formerl y entomology shop where petroleum contamination was identified. Soil contamination was
excavated from the site in June 2017. Naphthalene contaminations remain in the groundwater at concentrations
exceeding North Carolina 2L Groundwater Protection Standards. The I urpose of the injection activit y is to
achieve site closure using potassium persulfate injections. The iniectant material is Provect-OX2 which is an
extended release source of potassium persulfate plus a ferric iron activator. Injections will be completed in four
direct push borings (see attached Figure H.1 ) at hot spot identified near performance wells RW-11. The direct
push borings will be advanced to a predetermined depth (see attached Table 1) then retracted 3.5 feet to ex pose
the injection interval. After injection is completed the tooling will be retracted another 3.5 feet to ex pose the
next injection interval. This process will be repeated until all 10.5 feet has been in jected. Performance
monitoring will be initiated one month after the injections and continue quarterl y for one year. If needed a
second injection event will be completed following the initial vear of performance monitorinQ..

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 monitoring will be completed quarterl y startinQ one month after the com pletion of in jections to
allow the sodium persulfate to dissi pate. During the first round of sam plim!. prior to purging. field testing for
sodium persulfate will be conducted. If any persulfate is detected in groundwater durin~ this test. field parameters
will not be measured. When uroundwater is sam pled with persulfate present it interferes with water q uali ty
probes and gives false readings. Groundwater sam ples will be anal vzed for na phthalene for four quarters.
Monitoring data will be utilized to determine if additional injections are re quired.

1. Contaminants at this site are limited to naphthalene in monitoring well
RW-11. No plume map was drawn for this site in the latest report
submitted to NCDEQ. Injections are designed to address remaining
contaminants at this monitoring well.
2. The cross section is from the 2002 Remedial Investigation. No borings
have been completed at this site and all information regarding geology
was obtained from historical reports.
3. The potentiometric surface map was obtained from a 2006 long term
monitoring report. Sampling at this site by URS is limited to one well.
Therefore, historical data was utilized to determine groundwater flow
direction. The data from the 2006 report is consistent with the overall
direction of groundwater flow in all historical reports reviewed.
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
injection, location, and quantity of material to be injected are included in Table 1.
K. Total gallons to be injected was calculated from planned pounds of water to be
injected in the approved work plan.
