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 .02201
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 (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 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.
Print Clearly or Type Information. Illegible Submittals Will Be Returned as Incomplete.
DATE: January 22 , 20 20 PERMIT NO. W10300427 (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:
Permit No.

BOUNDARIES MAY BE SUBMITTED IN LIEU OF GEOGRAPHIC COORDINATES.
G. TREATMENT AREA
Land surface area of contaminant plume: —6,000 (above GCLs) square feet
Land surface area of inj. well network: <10,000 square feet (< 10,000 ft2 for small-scale injections)
Percent of contaminant plume area to be treated: —75% (must be < 5% of plume for pilot test injections)
Deemed Permitted GW Remediation NOI Rev. 10-14-2019 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 purpose, scope, goals of the proposed injection activity:
The contamination is from a Mav 1990 Gasoline USTs release and the site has impacted eroundwater above the
NCDEQ GCLs or was recently above GCLs. S&ME propose to install three to four oxygen releasingsocks
ocks
(Provectus ORS) socks in wells with concentrations greater than their respective GCLs (MW-13, MW-104, MW-
105, and MW-106,). Also, plan to install PRP Wellbooms (Unirem Tech) in the wells with free product (MW-
01R and MW-101). The remediation goal is to reduce the plume below GCLs.
J. WELL CONSTRUCTION DATA
(1) No. of injection wells: Proposed 6 Existing (provide NC Well
Construction Record (GW-1) for each well)
(2) Appx. injection depths (BLS): —10-31
(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

Top of casing elevations for MW-01, MW-10, MW-13, MW-101, MW-104 taken from Interim Report of Action sin Response to NCDENR NORR prepared by S&ME
dated May 6, 2011.
No well construction information located for MW-15, except Top of Casing Elevation taken from Analytical Data Tables for North Carolina Dry -Cleaning Solvent
Cleanup Act Program, Former Sno-White Cleaners (DSCA ID No.: 60-0026) prepared by ATC Associates of North Carolina, P.C. dated March 26, 2010.
- If Free Product is present in a well, groundwater elevation was calculated by: [Top of Casing Elevation - Depth to Water] + [free product thickness x 0.8581]
