NOTIFICATION OF INTENT (NOI)TO CONSTRUCT OR OPERATE INJECTION WELLS
The following are`permitted by rule"and do not require an individualpermit when constructed in accordance
with the rules of 15A NCAC 02C.0200(NOTE:This form must be received at least 14 DAYS prior to iniection)
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.02251 or TRACER WELLS(15A NCAC 02C.02291:
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 Iniection 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.

H. INJECTION ZONE MAPS—Attach the following to the notification.
Deemed Permitted GW Remediation NOI Rev.2-17-2020 Page 2

(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 SEE ATTACHED FIGURES 3 AND 5
(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.SEE ATTACHED FIGURES 6-8
(3) Potentiometric surface map(s)indicating the rate and direction of groundwater movement,plus existing
and proposed wells. SEE ATTACHED FIGURE 4
L 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:
Trichloroethene(TCE)was detected in soil samples collected near Press 2 at concentrations above
the groundwater protection standard.TCE was detected above its 2L Standard in monitoring wells MW-2,
MW-4,and MW-7.The suspected source of the chlorinated solvents is maintenance of the press by outside
vendors as these compounds have not been used at the site.
The purpose and goal of the injection strategy is to reduce the concentration of VOCs found in
groundwater at MW-2, MW-4. and MW-7. Passive hydrogen diffusers will be placed in existing monitoring
wells MW-2.MW-4,and NM-7,connected to a hydrogen gas suppler ugh a regulator,allowing hydrogen to
dissolve into the groundwater providing an anaerobic environment for reductive dichlorination.
J. WELL CONSTRUCTION DATA
(1) No.of injection wells: _ Proposed 3 Existing(provide NC Well
Construction Record(GW-1)for each well)SEE ATTACHED TABLE 1
(2) Appx.injection depths(BLS):_30
(3) For Proposed wells or Existing wells not having GW-Is,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
K. INJECTION SUMMARY
NOTE. Only iniectants approved bi,the epidemiology section of the NC Division offublic Health.Department
of Health and Human Services can be infected. Approved iniectants can be found online at
hft://deg.nc.gov/about/divisions/water-resources/water-resources-permits/wastewater-branch/ground-water-
protection/eround-water-approved-injectants. All other substances must be reviewed by the DHHS prior to use.
Contact the UIC Praeram 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 iniectants are to be used use N/A.

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.
Remedial monitoring will consist of a pre-injection sampling event and semi-annual followup
sampling events, as needed, until concentrations are below the 2L Standards. The pre-injection
monitoring event will include sampling monitoring wells MW-2, MW-4, MW-7, MW-8D, and
MW-9. Subsequent monitoring events will include each of the 13 wells on-site. Each monitoring
event will consist of sampling groundwater in the impacted monitoring wells for volatile organic
compounds. Field measurements of groundwater elevations, conductivity, dissolved oxygen,
oxidation-reduction potential,pH, and temperature will be recorded.
