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 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 .0225) 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.

The subject site is presently occupied and operating as a Bojangles Restaurant. The site
was the historical location of a commercial business with an underground storage tank
(UST) that leaked (>25 years ago) gasoline petroleum hydrocarbons into the subsurface,
resulting in impacts the local soil and groundwater regimes. These impacts were
discovered in August 2016. AST has confirmed the presence of light non aqueous phase
liquids (LNAPL), which are the primary focus of site remediation. None of the former UST
system remains onsite, with its suspected location indicated on Figure 1-1.
ATC has indicated that they would like to perform an in -situ Ivey -soli SERF application at
three (3) injection wells (IW): MW-2, MW-4, and MW-5, comprised of 300 to 500 Gal. of
diluted Ivey -sot° 103 at each IW. Then following a residence time of --24 to 48 hours, they
would perform an AFVR event, at two (2) Extraction Wells (EW) MW-6 and MW-7, to
remove liberated sorbed, globule, and LNAPL phase COC mass.
The effectiveness of these applications will be limited to the hydraulic communication
between the IW and EW locations, and contact that is achieved with the sorbed, globule,
and LNAPL mass, within the smear -zone. IVEY understands all IW locations are
screened across the anticipated COC smear -zone, and 6.25 inches in diameter.
This proposal is based on site information provided by ATC to IVEY, via email
communication on February 13, 2021. This was limited to the Groundwater Monitoring
Report (April 13, 2020), three (3) bore hold (BH) logs (MW-1, MW-2, and MW-3), and the
IVEY 1-page writable site evaluation. This information, collectively, provided a site
description, spill history, hydrogeological data, site figures, well construction details, and
soil and groundwater related data.
IVEY will provide application illustrations and an animation link within this document to
convey how in -situ lveysoI® `Push-PullT""' injection and extraction events are undertaken,
and how the observed COC and LNAPL contaminant mass remediation can be achieved.
Client testimonials, published case studies, and related technical information will be
appended to this proposal, and/or provided under separate cover, to augment the
information presented in the proposal. Three-dimensional animations of in -situ Ivey-sol®
`Push -Pull' and `Sweep' applications are provided via an internet link in Section 3.1.
1.1 TERMS OF REFERENCE
The background site information provided to IVEY by ATC include:
• Land use of the site is understood to be Commercial;
• COC impacts in gasoline range including: BTEX and LNAPL;

1.2 CHALLENGE & OPPORTUNITY
Normally hydrophobic organic chemicals (HOC), including low (Le., BTEX, MTBE and
Gasoline), medium (i.e., Diesel and PAH), and high (i.e., Motor Oil, Lubricants, Bunker-
C) molecular weight petroleum hydrocarbon contaminants (C6 to C5o range) exhibit limited
solubility in groundwater, this is also true of chlorinated solvents, and as a result, these
contaminants tend to partition and sorb (i.e., absorb and/or adsorb) onto the soil or
weather bedrock matrix surfaces, and at high concentrations, they may form a free
floating sheen or droplets (LNAPL) residing in pore spaces. For the purpose of this
proposal HOC will be interchangeable COC. COC sorption and/or the formation of LNAPL
(free product) will limit the Availability' of HOC for in -situ remediation. Hence they are
less Physically Available' for pump and treatment methods; less Biologically Available'
for bioremediation, and less 'Chemically Available' for chemical REDOX type chemical
treatment. Hence COC (i.e., sorbed, dissolved, and/or free phases) can persist in soils,
sediments, and fractured bedrock and/or groundwater systems for extended periods of
time. This explains why some remediation projects are slow, costly and/or fail to achieve
site remediation objectives.
A concern regarding contaminant sorption, and its reduced availability for remediation,
has been well cited in literature as demonstrated by the following sample quotation:
"During the past decade, much discussion has centered on the unavailability of absorbed
compounds to soil microorganisms; it is generally now assumed that desorption and diffusion of
bound contaminants to the aqueous phase is required for microbial degradation."
(W.F. lnskeep, J.M. Wraith, C.G. Johnston, Hazardous Substance Research Center, 2005).

Generally, if we can overcome COC contaminant sorption and/or LNAPL formation, we
can improve all forms of physical, biological, and chemical - air (vaporNOC), soil, and
groundwater COC (LNAPL) remediation.
The application and use of Ivey-sol® surfactant products and processes provided a unique
methodology to enhance COC remediation at many sites globally. This is evidenced by
many conference paper and poster presentations, peer reviewed journal publications,
published case studies, magazine articles, and client testimonials (See Appendix).
1.3 FIELD SCALE OBJECTIVE
The main focus for the Iveysol® applications would be to demonstrate effective LNAPL
remediation within the COC plume area on -site. This will involve the completion of one
(1) significant `Push -Pull' application at three (3) IW's (i.e. MW-2, MW-4, and MW-5) with
extraction at two (2) EW's (i.e., MW-6 and MW-7) as the scope of work.
Although the spill volume and mass remain unknown, this approach should produce a
favourable LNAPL mass reductions, toward the site remediation goal. The remediation
of the ❑bserved LNAPL will require the application of Ivey-soI® 103 based ❑n the
characterization of the historical spill, and vapor, soil and groundwater analysis. This
recommendation is based on the Ivey -soli guidance Table 1-1.

2.1 IVEY-SQL® TECHNOLOGY
Ivey-sol® Surfactant Technology is comprised of several patented and/or proprietary non-
ionic surfactant formulations (biodegradable) that have the unique ability to selectively
desorb sorbed (Le., absorbed and/or adsorbed) COC, and make NAPL miscible in the
aqueous phase. This includes the broad range of Light Non Aqueous Phase Liquids
(LNAPL) like petroleum hydrocarbons (API >10), and the Dense Non Aqueous Phase
Liquids (DNAPL) including chlorinated solvents (API <10). Ivey-sol® has also been used
for the remediation of recalcitrant compounds within fine to coarse soil textures, marine
sediments and fractured bedrock, and within the groundwater table and associated
smear -zones and capillary zones, with favorable results.
The three (3) main Ivey -soli' application processes that were developed over two (2)
decades for enhancing in -situ and ex -situ remediation of: Vapors/VOC, Soil/Bedrock
(sorbed), and Groundwater (Dissolved, LNAPL, and Smear -Zone) COC site remediation,
are outlined as follows:
• SER® Surfactant Enhanced Remediation
In -situ and ex -situ application processes to liberate sorbed and/or LNAPL COC making
them more miscible (soluble) and more `Physically Available' for mass removal via
`Sweep' or `Pump & Treatment' type remediation methods. It is also very effective for ex -
situ soil washing of COC for soil texture with >85-90°k coarse textures;
• SEB® Surfactant Enhanced Bioremediation
In -situ and ex -situ application processes to liberate contaminants making them more
`Biologically Available' for microbial (bacteria) and associated enzymatic degradation.
SEB® improves both in -situ and/or ex -situ bioremediation treatment methods including
bio-stimulation, bio-augmentation and newer enhanced biological techniques for aerobic,
anaerobic and facultative microorganisms.
• SEC® Surfactant Enhanced Chemicalization
In -situ and ex -situ application processes to liberate contaminants making them more
`Chemically-Available'for chemical REDOX (i.e. Reduction or Oxidation or combined) by
chemical agents. SEC® improves the availability of the contaminants to the chemical
REDOX, facilitating improved contact and reaction kinetics, to enhance the associated in -
situ and/or ex -situ chemical reagent degradation of target COC.
2.2 IVEY-SOL® WATER CLUSTER SIZE REDUCTION
IveysoI® surfactants, when introduced into contaminated soil and groundwater regimes,
can reduce the surface tension of water from 73 dynes to <30 dynes. This capacity
improves the wetting ability (capacity), and movement, of the aqueous phase in the soil

and groundwater (unsaturated and saturated) zones, and the relative `Hydraulic
Conductivity' (K), while Ivey-sol® is present. Once Ivey-sol® applications are completed
the original site conditions return to normal.
The Ivey-sol®surfactants accomplished this by reducing the size and formation of large
water -clusters to smaller water -clusters (See Figure 2-1 below). In doing so, the Ivey-sol®
allows the water clusters to become smaller, and to penetrate into less permeable soils
such as: clays, silty -clay, silty -sand, sands with silty and clay content to weathered and
fractured bedrock, improving LNAPL and COC remediation.
Very Little Aggregation to Larger Clusters
Much Greater Aggregation to Larger Clusters

2.3 ADVANTAGES AND DISADVANTAGES
As detailed in the above sections, Ivey-s❑r makes the desorbed contaminants more
`Physically -Available' for extraction by in -situ `Sweep' or `Push-PuIITM', MPE, Pump and
Treatment and ex -situ Soil Washing; more Biologically -Available' for Bioremediation (in -
situ and/or ex -situ); and by increasing the dissolved aqueous -phase contaminant
concentrations which improves their `Chemical Availability' for Reductive -Oxidative
(REDOX) chemical treatment (in -situ & ex -situ). This is also true when combining multiple
physical, biological or chemical applications, or when rolled out in a stepwise manner.
To expand on the flexibility, at full-scale, ATC could commence a physical `Sweep' mass
recovery approach, and if site conditions permitted, then flexibly modify the remediation
strategy to include in -situ SEB® and/or in -situ ISCO and/or conclude site closure by
conventional MNA (Monitored Natural Attenuation).
The following table lists several advantages and disadvantages associated with the Ivey-
sol® remediation.

may suppress VOCs, making them less
detectable by standard handheld vapor meters
[lvey-sol can aid VOC reductions when in-
door air quality is a remediation driver];
vi) When used for SEC®, the Ivey -soli' may
consume some of the REDOX reagents being
introduced [Although limited as application
concentrations are generally below the CMC —
Critical Micelle Concentration];
vii) During SER®, and effective improvement in
mass recovery, bacterial pluming in the soil
and groundwater regimes may be observed.
Ivey -soli® is free of unwanted regulated impurities including: PFOA, PFAS,
1,4-Dioxane, Dioxins, Furans, PCB, and tested and free of US EPA regulated
compounds. A claim no other remediation technology is making!

2.4 IVEY-SOL® MECHANISM
The IveysoI® surfactants can selectively desorb and/or dissolve (i.e. make miscible) COC
at the molecular level, as microscopic `surfactant -hydrocarbon -water' partial non -
encapsulations, called partial micelles, well below the critical micelle concentration
(CMC). This capacity is unique to Ivey-sol® and explains why lower Ivey-sol® application
concentration show efficacy for COC mass removal. This is particularly effective on
treating LNAPL and DNAPL contamination.
Through selective desorption and dissolution, below the CMC, Ivey-sol® significantly
increases the availability of the target COC for all forms of in -situ or ex -situ physical,
biological, and/or chemical remediation. The IveysoI® mechanism on COC is illustrated
in Figure 2-2 below for LNAPL, sorbed and dissolved phase COC.

In brief, an in -situ Ivey-sol® SER® application can accomplish three (3) feats. First, it
overcomes the `Limitation' challenges associated with NAPL dissolution, contaminant
sorption and low COC solubility. Secondly it lowers the relative surface tension of water
improving both its wetting and associated hydraulic conductivity (K) properties, while the
IveysoI® is present, across a broad range of soil textures. Third, through its selective
dissolving of contaminants (COC) below the CMC, whereby it broadens the range of
contaminants that can be treated, and enhances in -situ and ex -situ physical, biological,
and chemical remediation methodologies, including combinations thereof.
3.0 IVEY-SOL® APPLICATION (DETAILED)
This section will detail the in -situ application methods for the Ivey-sol® surfactant
remediation products, as they relate to the subject site. Specifically how they are
employed for IW and EW `Push -Puff SER° strategies to aid elimination of observed COC,
including: LNAPL, vapor intrusion, sorbed, and dissolved phases, within the smear zone
associated with local groundwater elevation fluctuations at a typical site.
3.1 IVEY-SOL® `PUSH-PULL' APPLICATIONS
Figure 3-1 illustrates the Ivey-sol® `Push-PullTMin-situ approach when using [Ws
designed and installed to target the IveysoI® injections into the subsurface zone(s) of
identified COC, including LNAPL, within the saturated and unsaturated smear -zone. IVEY
assumes the well screen interval of these [Ws will cover the entire smear- zone, and
applicable capillary zone. This approach would desorb and make the targeted COC and
LNAPL more miscible in groundwater, whereby they would be more Available' for

physical mass extraction at the same IW locations, or at nearby groundwater Recovery
Wells (RW) locations (see Figure 3-1).
Note: I VEY generally recommends, where existing well infrastructure is limited, installation of
4 inch (100 mm) diameter injection wells (I W), screened across the COC plume and
groundwater table, to improve the Ivey-sol° `Push-PullrM' application injection diffusion
radius (idr), resulting in improved COC plume contact and COC or LNAPL or DNAPL
mass recovery. Further, these larger diameter IW's can serve as multi -purpose wells;
used for the Ivey-soI injections, can be employed as extraction wells (RW), and later
as post-remediation monitoring wells (MWs) to help facilitate regulatory site closure or
closure by a risk assessment. This type of IW is referred to as a Triple -Use -Well by
1VEY and only cost 10% to 15% more to install than 2 inch (50 mm) wells.

The Ivey-sol® `Push-PullTM' process is generally easy to apply, and often a very effective
method to remove COC sorbed phase, dissolved phase, and LNAPL (i.e. LNAPL and
DNAPL) contaminant mass within in -situ environments.
Figure 3-2 illustrates a typical field -scale Ivey-sol® `Push-Pu11TM' application with
anticipated idr shown for the injected Ivey-sol® volume associated with each injection
`Push' which after allowing a prescribed `Contact Time' is then extracted - `Pull'- from the
IW and RW locations. The idr values shown in the legend are based on 100 mm (4 inch)
diameter wells, so should be viewed as conservative, as several site specific variables
(i.e. soil texture, soil compaction, groundwater elevation, K, contaminant type, porosity,
etc.) would affect the actual idr realized for different site conditions.

3.3 IVEY-SOL® `PUSH-PULL' ANIMATION
The Ivey -sole `Push-Pu117M' and Sweep' animations, depict typical in -situ application
strategies, to desorb COC sorbed to soil and bedrock surfaces, dissolution of dissolved
and free phase LNAPL contaminants into the groundwater for enhanced remediation.
This occurs in the vicinity of IW locations, following a 'Push' injection, and after a brief
contact time (hours to days). The liberated contaminants are then extracted at each IW,
for the 'Pull'to recover the liberated contaminant (COC) mass at RW's.
For most sites, only a limited number of `Push-Pul1TM' or `Sweep' events are required to
achieve significant advancements toward site -specific remediation goals. These
applications can be completed daily, weekly, or monthly depending on the project logistics
and budget. The web based 3-dimensional IveysoI® animation link is available as follows:
http://wvyw.iveyinternational.com/videopresentation
3.4 IVEY-SOL® FIELD APPLICATION AFVR
For calculating the required Ivey-sol® 103 volume, and costing, IVEY will assume the field
scale injections will be limited one (1) `Push -Pull' Ivey-sol® application event, involving
300 to 500 Gal. of 4% Ivey-sol® at each of three (3) IW locations (MW-2, MW-4, and MW-
5), in the vicinity of the for UST source area, that are given a —24 to 48 hour residence
time (post injection), before undertaking an AFVR event at EW's (MW-6
IW's MW-2, 4, 5
To achieve a 4% Ivey -sole dosage in the proposed 300 to 500 Gal of clean water, for
injection at the three (3) IW's, this would require 12 to 20 Gal. of Ivey-sol 103, diluted into
288 to 480 Gal. of clean water, respectively, to be injected at each IW location, as per
ATC's requested application, followed by a residence time, prior to undertake an AFVR
event at MW-6 and MW-7. 1,500 gal = 60 gal surfactant 1,440 gal water
At the conclusion of the Ivey-sol® applications, ATC may perform an `Optional' clean -
water flush at involved wells, to remove residual IveysoI® and/or liberate COC.
Note: During the field applications, ATC could measure the groundwater elevations at
nearby MW locations to evaluate the extent of groundwater table mounding and lateral
dispersion of injected Ivey -sot, and modify the Ivey -so! volume injected to achieve
increased pore volume contact within the COC and LNAPL plumes.
Volume of Ivey -so' required for the subject site application, involving four (4) IW locations,
at 4% in 300 to 500 Gal. per IW, would be as follows:
Volume = 1 Event x 3 IW x (12 to 20 Gal Ivey-sol® 103 / 300 to 500 Gal. Injection/IW)
= 36 to 60 Gal Ivey -sole 103 Per Event

3.5 IVEY-SOL SURFACTANT `REAL-TIME' FIELD TEST KITS
IVEY has developed a real-time field surfactant test that is easy to use and that helps
clients verify when and where the Ivey-sol®, and liberated COC, are relative to injection
well (IW) and recovery well (RW) locations on a site. It can also indicate when they have
extracted enough groundwater associated with each ivey-sol® `Push -Pull' injection event.
For the subject site the `Pull' will be the AFVR.
A copy of this field test method will be included in the Appendix of the proposal. It should
be noted that IVEY has developed a new field test method (See Figure 3-3) that has been
used globally with over 20,000 individual tests completed since 2016.
Test results have shown a >96% correlation with laboratory tests. This new field test
method (a.k.a. Field Surfactant Test Kit = 100 test/ kit) is now available for general use.
Test kits can be sources from IVEY, or through local distributors.
Figure 3-3: NRW Ivey-soi® Field Surfactant test. Illustrates 3 time -based
Tests - baseline through increasing [Ivey -soli
If ATC wants to have the analytical capacity to analyze for Ivey-sol® in groundwater
samples, IVEY has established three (3) USEPA approved analysis methods. These
analytical laboratory methods are detailed in a technical handout included in the Appendix
of this proposal.

Special `Optional' Offer
If required IVEY can provide an on -site IveysoI® application specialist on -site at a rate of
$1000.00 per day (not including Transportation, Meals, and Accommodations). IVEY
would provide logistical support, on -site training relating to injection and extraction
(lessons learned), and associated field surfactant testing kit, and on -going technical
support as required. However, with COVID-19 we are providing remote support to >80%
of site applications.
3.6 DETAILED IVEY-SOL® PUSH-PULL' WITH AFVR
Based on ATC's requested `Push -Pull' pairing an Ivey-sol® injection with AFVR
extraction event, the following steps would describe the general actions associated
with the proposed in -situ Push -Pull' application:
Baseline Monitoring - Field sampling and testing of groundwater quality, groundwater
elevation survey, and gauging LNAPL thickness, to establish 'Baseline' conditions prior
to the Ivey-sol® and AFVR 'Push-Pull'application. This will allow for post Ivey-sol® - AFVR
application evaluation of efficacy. This should be completed at wells on -site.
ATC would like to act according to the following `modified' application strategy:
i. Perform baseline monitoring, and/or testing to extent required;
ii. Add 300 to 500 Gal. of 4% Ivey-sol® 103 at each of the three (3) designated IW
locations (i.e. MW-2, MW4, and MW-5) by gravity or low pressure injection;
iii. Allow for residence time of —24 to 48 Hours (IVEY usually suggests Hours
for LNAPL, but some clients experienced favorable results after several days);
iv. Undertake groundwater LNAPL gauging at involved well locations;
v. Perform AFVR at -E-Ws: MW-6--and M-W 7, to remove injected Ivey-sol and
liberated COC and LNAPL mass; IW's MW-2, 4, 5
vi. Use Real Time Field Surfactant Test Kits to help optimize the Ivey-sof® application
extraction process (Section 3.5) and to confirm `Push -Pull' completion, and to
minimize groundwater extraction volume for on -site or off -site treatment;
vii. Gauging of involved well locations for LNAPL thickness, and the collection of
groundwater quality samples to evaluate 'Push -Pull' application performance; and
viii. Repeat process [IVEY usually suggest a minimum of three (3) events].
4.0 ESTIMATED COST
The project cost to undertake the ATC scope of work, at the subject site is detailed below,
based on injecting a 300 to 500 Gal. volume of 4% lvey-sol® 103 at MW-2, MW-4, and
MW-5. If ATC wants to have an IVEY Surfactant Remediation Specialist on -site, that
would be an extra cost, otherwise remote support will be available.
