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 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 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 REMEDLATION (15A NCAC 02C .02251 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.
DATE: February 24 , 2020_ PERMIT NO. W10400543 (to be filled in by DWR)
NOTE- If this NOI is being submitted as notification of a modification of a previously issued NOI for this site (e.g.,
different injection wells, plume, additives, etc.) and still meets the deemed permitted by rule criteria, provide the
previously assigned permit tracking number and any needed relevant information to assess and approve injection:

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.
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:
The contamination present in the groundwater is a result of a historic release at a former coatings manufacturing
facility. An air sparge/soil vapor extraction system is currently in operation; however, some additional injection
is being proposed downgradient. The ,goal of the injection is to prevent contamination from entering the creek
utilizing bioremediation. Fifteen injection locations are proposed, and each point will receive approximately 250
pounds of calcium peroxide in a 300-gallon slurry mix. The proposed injection interval is from 6 to 16 feet BLS
through direct push rods.
WELL CONSTRUCTION DATA
(1) No. of injection wells: 15 Proposed 0 Existing (provide NC Well
Construction Record (GW-1) for each well)
(2) Appx. injection depths (BLS):_6 - 16 feet
(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
INJECTION SUMMARY
NOTE: Onlv iniectants avvroved by the evidemioloev section of the NC Division ofPublic Health. Department
of Health and Human Services can be injected. Approved iniectants 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 Pro ream for more info if you wish to 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.
