WI0700535_Notification of Intent (NOI) – GW Remediation_20230203

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 REMEDIATION (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: January 31 , 2023 PERMIT NO. (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:

G. TREATMENT AREA
Land surface area of contaminant plume: 190000 sft square feet
Land surface area of inj. well network: 800 sft square feet (< 10,000 ft2 for small-scale injections)
Percent of contaminant plume area to be treated: 0.42% (must be < 5% of plume for pilot test injections)
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 (See attached Figures); 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. (See attached Figures)
(3) Potentiometric surface map(s) indicating the rate and direction of groundwater movement, plus existing
and proposed wells. (See attached Figures)
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:
Historically, ENCEE Chemical has reportedly stored bulk quantities of various chemicals, compounds and
solvents in drums, bulk, and pre -packaged quantities which may have contributed to shallow ,groundwater
volatile organic compounds (VOCs) and metals contamination. A pilot study is being conducted to evaluate the
effectiveness of hybrid treatment of In -situ Chemical Reduction (ISCR) and anaerobic biodegradation (ERD)
remediation in the source areas surrounding monitoring wells MW-4 and SW-2 for treating VOCs and metals in
shallow groundwater. The pilot injections will be conducted through DPT temporarinjection points (borings)
which will be abandoned after the completion of injections. The pilot study will evaluate the suitability of ISCR
and ERD for full scale remedial application. DPT injection point schematic is included in the Attachment.
J. WELL CONSTRUCTION DATA
(1) No. of injection wells: 20 DPT borings/injection points (not injection wells) Proposed;
None Existing (provide NC Well Construction Record (GW-1) for each well)
(2) Appx. injection depths (BLS): 5 to 20 feet below land surface
(3) For Proposed wells or Existing wells not having GW-1s, 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
A Temporary DPT Injection Point Schematic is included in the Attachment.
K. INJECTION SUMMARY
NOTE. Only iniectants approved by the epidemiology section of the NC Division of Public Health. Department
of Health and Human Services can be injected. Approved iniectants can be found online at
hiip: Hdeq.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 DHHS prior to use.
Contact the UIC Pro ream for more info if you wish to eft 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.
SDS sheets for the below listed Injectants are included in the Attachments. A list of Amendments
proposed for Pilot Study injection, along with their composition and comparison to NCDEQ
approved Amendments is included in the Attachment.

Notes:
All the ingredients in GeoForm® ER and GeoForm® Soluble are on the NC approved list. The list of ingredients is provided below:
1. Ferrous sulfate is on the NC approved list
2. ZVI is on the NC approved list
3. Organic carbon is on the NC approved list
4. Starch is on the NC approved list
5. Magnesium hydroxide [Mg(OH)2] is on the NC approved list
All the ingredients in MetaFix® are on the NC approved list. The list of ingredients is provided below:
1. Several forms of activated carbon are ingredients of materials on the NC approved list (i.e., BOS100, BOS200, Petrofix)
2. Sulfide, as calcium polysulfide, is on the NC approved list; and Fe, in the form of ZVI, is on the NC approved list;
as a result the ferrous sulfide (FeS) in MetaFix I-7A should be acceptable.
3. All ZVI materials have iron oxide (FeO) layers on their surfaces; therefore the iron oxide in MetaFix I-7A should be acceptable.

7. Handling and storage
Handling
Technical measures (e.g. Local and Avoid dust formation and control ignition sources. Employ
general ventilation): grounding, venting and explosion relief provisions in
accordance with accepted engineering practices in any
process capable of generating dust and/or static electricity.
To identify additional system design issues with respect to
dust hazards, it is recommended to conduct a dust hazard
analysis using information and sources provided in the
OSHA Fact Sheet on combustible dusts (DSG 3/2008) and
addressing enforcement issues identified in the Combustible
Dust National Emphasis Program (Reissued) (CPL 03-00-
008, 3/11/08)
Provide readily accessible eye wash stations and safety
showers. Provide natural or explosion -proof ventilation
adequate to ensure concentrations are kept below exposure
limits.
Safe handling advice: Wash hands at the end of each workshift and before eating,
smoking or using the toilet.Avoid dust formation. Do not
breathe dust or vapor. Emergency showers and eye wash
