See the attached original UIC permit application for details concerning items in Section 3 for
NCDOT Site #32. Pepsi Bottling Venture's (PBV) Beverage Remediation Product (BRP) will
In -Situ Groundwater Remediation Application Rev. 8-28-2017 Page 4 of 12

replace the function and use of sodium lactate as described in the original UIC permit
application. North Carolina Dept. of Transportation requests that NCDEQ write the permit to
allow the injection of any product on the NCDEQ list of "Additives or Tracers Approved by NC
DHHS to Inject into Groundwater". This will allow NCDOT through its consultant to continue
with remediation efforts even if there is a suspension of supply of BRP.
(A) MSDS, concentration at the point of injection, and percentage if present in a mixture with other injectants;
There is no Material Safety Data Sheet (MSDS) available for BRP. Code of Federal Regulations
29CFR1910.1200(b)(5)(iii) exempts food, food additives, color additives, etc. from MSDS
requirements. BRP consists of water, high fructose corn syrup (HFCS) and a small quantity (less
than 0.5%) of other food grade ingredients approved for human consumption by the US FDA
(various flavorings, food colorants, compounds to preserve product freshness, and other
substances). HFCS consists of 55% fructose (C6H12O6) and 42% glucose (C6H14O7). BRP is
included on the NC DWQ-UIC's List of Approved Injectants.
BRP is typically delivered to the injection site in 2,500-gal batches. At another NCDOT
injection project (Former ATL Site 003), a laboratory assessment of total organic carbon (TOC)
and solution density in 2,500 gallon batches of BRP found the following:
i. The minimum TOC concentration was 21.1 g/L or 52.7 g/L as HFCS. This is equivalent
to 5.22 wt % or 4.06 % vol/vol and translates into 1,101 lbs of HFCS in the 2,500-gallon batch.
ii. The maximum TOC concentration was 89.2 g/L or 223 g/L as HFCS. This is equivalent
to 20.7 wt % or 17.2 % vol/vol and translates into 4,653 lbs of HFCS in the 2,500-gallon batch.
iii. The mean TOC concentration was 42.1 g/L or 105.2 g/L as HFCS. This is equivalent to
10.2 wt % or 8.10 % vol/vol and translates into 2,196 lbs of HFCS in the 2,500-gallon batch.
iv. The median TOC concentration was 38.0 g/L or 95.0 g/L as HFCS. This is equivalent to
9.24 wt % or 7.31 % vol/vol and translates into 1982 lbs of HFCS in the 2,500-gallon batch.
We will add sodium bicarbonate and sodium phosphate as necessary to buffer the aquifer and to
provide for microbial production of adenosine triphosphate (ATP). ATP is linked to the energy
required for respiration, synthesis, growth, and reproduction of microbial mass. MSDS
information for Sodium Bicarbonate and Sodium Polymetaphosphate (phosphorous) is included
in Attachment 2.
(B) The source of fluids used to dilute, early, or otherwise distribute the injectant throughout the injection zone. If any well
within the area of review of the injection facility is to be used as the fluid source, then the following information shall be
submitted: location/ID number, depth of source, formation, rock/sediment type, and a chemical analysis of the water from
the source well, including analyses for all contaminants suspected or historically recognized in soil or groundwater on the
site;
We will use the municipal water supply system as the source of water to carry, dilute and
distribute the injectant.
(C) A description of the rationale for selecting the injectants and concentrations proposed for injection, including an explanation
or calculations of how the proposed injectant volumes and concentrations were determined;
We have defined the rough dimensions of the aquifer study area to be approximately 1-acre as
shown in Figure 17. The static water table is roughly 15 ft bls (below land surface) and the
deepest on -site monitor well (32-DW-1) is approximately 65 feet bls (not including deep well
In -Situ Groundwater Remediation Application Rev. 8-28-2017 Page 5 of 12

32-MW25). Therefore, the thickness of the aquifer study area is 50 ft. Assuming an effective
porosity of 45% for the aquifer, the volume of groundwater within the aquifer study area is the
following:
43,560 ft2 x 50 ft x 0.45 = 980,100 ft3
980,100 ft3 x 7.481 gal/ft3 = 7,332,128 gal
7,332,128 gal x 3.78 L/gal = 277715.44 L
Based on sampling results from the last monitoring event held in March 2018, the average pH
(excluding 32-DW-1 because of likely grout contamination) is 5.25 (Table 2). To adjust the pH
introduced to neutralize the pH of groundwater alone is as follows:
5.25 x 10-6 moles/L x 84.01 g/mole = 0.000472 g/L
0.000472 g/L x 27,715,444 L = 13,093 g
13,093 grams (13.09 kilograms) of 27,715,444 liters of groundwater from a pH of 5.25 to a pH
of 7, it follows:
H++ HCO3- H2CO3
Thus, it will require one mole of bicarbonate to neutralize each mole of hydrogen ion. PH is the
-log of the hydrogen ion's activity. Therefore, it follows:
pH = 5.25 all, _> 10-5.25 = 5.62x 10-6 moles/L
It will take 5.62 x 10-6 moles/L of bicarbonate to raise the pH of the groundwater to 7. The
molecular weight of sodium bicarbonate is 84.01 grams/mole. Therefore, the mass of sodium
bicarbonate that must be introduced to neutralize the pH of groundwater alone is as follows:
5.25 x 10-6 moles/L x 84.01 g/mole = 0.000472 g/L
0.000472 g/L x 27,715,444 L = 13,093 g
13,093 grams (13.09 kilograms) is 29 lbs. We expect that the injection rate at the site will be
low, and up to one week could elapse before the 2,500 gallons of BRP enters the aquifer. During
that period, aerobic metabolism will convert the HFCS to acetic acid at a ratio of 1:3 (i.e., for
each mole of HFCS that is consumed, three moles of acetic acid will be produced). Buffering of
the acetic acid will require the following:
0.75ga1 of HFCS x 2,500 gal = 1,875 lbs of HFCS
(1,875 lbs of HFCS) x (2Ob) x(1,000g)x f imole)4,720 moles
s kg 180.16E
25% of the 4,720 moles of HFCS converted to acetic acid = 1,180 moles of acetic acid, which
when dissociated could produce 1,180 moles of hydrogen ions (i.e. 1,180 moles of H+ or H3O+).
Neutralization the 1,180 moles of H3O+ will require the following mass of sodium bicarbonate:
1,180m Iles x 84.01 9 = 99,132E
mole
In -Situ Groundwater Remediation Application Rev. 8-28-2017 Page 6 of 12

.205
99,1321 x \i,000yl x (2 lkgbsl = 219 lbs
Once in the aquifer, initial metabolic utilization of HFCS by indigenous microbial populations
creates various carboxylic acids. These include, from most to least abundant, acetic, propionic,
butyric, valeric/pentanoic, and caproic/hexanoic acids. As conditions become more reducing,
microbial populations may produce comparable alcohols rather than acids (i.e. ethanol, propanol,
butanol, pentanol, etc.), which react with existing organic acids to form carboxylates/esters (e.g.,
ethyl-, propyl-, or butyl- acetate, propionate, or butyrate, etc.). Sufficient sodium bicarbonate
should be added to buffer in situ formation of organic acids from HFCS. The mass of sodium
bicarbonate should be sufficient to offset conversion of all the HFCS to acetic acid (i.e., an
additional 657 lbs of sodium bicarbonate). The silicate minerals comprising the aquifer matrix
may also release hydrogen ions through ion exchange. The magnitude of the phenomenon is
empirical and site -specific. In the absence of empirical data, we propose to increase the sodium
bicarbonate concentrations in the BRP by an additional 50% to a total of' 1,350 lbs
((29+219+657) x 1.5 - 1,350 Ibs).
Commercial suppliers provide food grade sodium bicarbonate (baking soda) in 50-1b bags.
Therefore, it will require approximately twenty-seven 50-1b bags of sodium bicarbonate to raise
the pH of groundwater from 5.25 to 7.00, maintain the pH of the BRP as the indigenous
microbial populations converts the HFCS to organic acids, and to account for ion exchange
effects with the silicate mineral phases in the aquifer matrix. If, during subsequent monitoring
work we determine that we have still not sufficiently buffered the aquifer, we will increase the
loading of the sodium bicarbonate up to its solubility in BRP (approximately 1,500 lbs).
Based on sampling results from the last monitoring event held in March 2018, the average total
phosphorus concentration 2.86 mg/L and the average orthophosphate concentration is 2.45 mg/L
(Table 2). We propose to add sufficient bioavailable phosphorous to the aquifer to bring the
phosphate concentration to 2.9 mg/L. The molecular weight of sodium polymetaphosphate is
611.77 g/mole of which sodium accounts for 22.98977 g/mole. Therefore, the total mass of
sodium polymetaphosphate that must be introduced in the initial injection to attain an average
aquifer concentration of 2.9 mg/L is as follows:
(2.9-2.45) mg/L x 27,715,444 L x 10-6 Kg/mg x 2.205 Ibs/Kg = 27.5 Ibs
Commercial suppliers provide food grade sodium polymetaphosphate in 50-1b bags. Therefore,
it will require approximately half of a 50-1b bag of sodium polymetaphosphate to provide a
concentration of 2.9 mg/L during the initial injection. We will closely monitor phosphorus
concentrations in the aquifer prior to and subsequent to the initial injection and adjust quantities
accordingly.
(D) A description of the reactions between the injectants and the contaminants present including specific breakdown products or
intermediate compounds that may be formed by the injection;
See the attached original UIC permit application. BRP will replace the function and use of
sodium lactate as described in the original UIC permit application. The original UIC permit
application contains details concerning reactions between the injectants and the contaminants
present including specific breakdown products or intermediate compounds that may be formed
by the injection.
Tables 2, 3 and 4 contain sampling results from the last monitoring event held in March 2018.
The laboratory report is included as Attachment 3.
In -Situ Groundwater Remediation Application Rev. 8-28-2017 Page 7 of 12

(E) A summary of results if modeling or testing was performed to investigate the injectant's potential or susceptibility for
biological, chemical, or physical change in the subsurface;
See the attached original UIC permit application.
(F) An evaluation concerning the development of byproducts of the injection process, including increases in the concentrations
of naturally occurring substances. Such an evaluation shall include the identification of the specific byproducts of the
injection process, projected concentrations of byproducts, and areas of migration as determined through modeling or other
predictive calculations.
See the attached original UIC permit application.
4. INJECTION PROCEDURE — Per 15A NCAC 02C .0225(e)(6), submit a table with a detailed description of the proposed injection
procedure that includes the following:
(A) The proposed average and maximum daily rate and quantity of injectant;
(B) The average maximum injection pressure expressed in units of pounds per square inch (psi); and
(C) The total or estimated total volume to be injected.
Depending on how BRP is prepared for transport at the PBV plant, a tanker or flatbed truck will
transport BRP to the site. We will transfer the BRP to a 3,210-gallon drainable HDPE horizontal
leg tank equipped with a 2-inch stainless steel ventral drain. Eductors (1.5-inch size) will be
mounted on both ends of the tank approximately 24 inches above the bottom. We will collect
BRP samples from the tank for laboratory QA/QC analyses of density and total organic carbon.
We will then circulate the BRP through the tank using the eductors with 2 centrifugal pumps.
The intake for one pump will be connected to the ventral drain and the intake of the second pump
will be a suction line lowered through the dorsal fill port. The total flow rate will be between
350 gpm and 400 gpm. As the solution circulates, our staff will slowly add twenty-seven to
thirty 50-1b bags of sodium bicarbonate (1,350 to 1,500 lbs total) and one half of a 50-1b bag of
sodium polymetaphosphate (25 lbs total). We will adjust the amount of phosphate in subsequent
events as needed to maintain a concentration of 2.9 mg/L in the aquifer. It will require 1 to 2
hours to add the bicarbonate and phosphate. The solution will continue to circulate for a
minimum of 2 hours after all components are added to insure dissolution of the granular products
and thorough mixing.
The site is an active asphalt plant and construction traffic may affect how we deliver the solution
to the five injection wells. If site conditions warrant, the solution will gravity feed into wells 32-
MW1, 32-MW8, 32-MW10, 32-MW17, and 32-MW18 from the mixing tank. The depth to the
static water table is approximately 15 ft bls. The height of the solution in the tank when it is full
is approximately 7 feet above ground surface. Therefore, the maximum injection pressure will
be approximately 10 PSI by gravity. If a pump is needed for injection, the pressure may be as
high as 50 PSI. If construction traffic precludes the use of a central tank, then smaller individual
tanks will be placed at each well and solution transferred to them from the mixing tank. Each
injection event will consist of one 2,500-gallon aliquot of BRP distributed between the five
injection wells.
The estimated total volume to be injected will be that volume required to develop and maintain a
microcosm that effectively dehalogenates groundwater contamination. Following the initial
injection(s), there is typically an acclimation period where microorganisms capable of halo -
respiration through hydrogenolysis become established and dominant. This typically takes 3 to
18 months. During that period, microbes will aggressively utilize the BRP and additional
injections will be required to maintain the system. The target concentration for TOC is >100
mg/L in the treatment area. We anticipate quarterly to semiannual injections during the first year
In -Situ Groundwater Remediation Application Rev. 8-28-2017 Page 8 of 12

of operation and injections on an as needed basis thereafter. The maximum total number of
injections in a five year period will be 20 for a total volume of 50,000 gallons.

or formation fluids outside the injection zone. The monitoring schedule shall be consistent with the proposed injection schedule, pace
of the anticipated reactions, and rate of transport of the injectants and contaminants.
Tables 1 and 2 present a list of all existing monitor wells. We will perform water level gauging,
field analyses and laboratory analyses for all wells. Groundwater sampling will occur as
follows:
• a sampling event immediately prior to injection.
• quarterly during periods of active injection.
• semiannually for two years after the final injections occur.
See the attached original UIC permit application for details concerning sampling methods and
data analyses.
8. WELL DATA TABULATION — Per 1 SA NCAC 02C .0225(e)(10), provide a tabulation of data on all existing or abandoned wells
within the area of review of the injection well(s) that penetrate the proposed injection zone, including monitoring wells and wells
proposed for use as injection wells. Such data shall include a description of each well's type, depth, and record of construction or
abandonment.
See the attached original UIC permit application for a tabulation of well data within the area of
review. The attached Table 1 updates the information found in Section F of the original
application.
9. MAPS AND CROSS -SECTIONS — Per 15A NCAC 02C . 0225(e) (11), provide scaled, site -specific site plans or maps depicting the
location, orientation, and relationship of facility components including the following:
(A) area map based on the most recent USGS 7.5' topographic map of the area, at a scale of 1:24,000 and showing the location
of the proposed injection site;
See attached Figure 1.
(B) topographic contour intervals showing all facility related structures, property boundaries, streams, springs, lakes, ponds,
and other surface drainage features;
See attached Figures 1, 2 & 4.
(C) all existing or abandoned wells within the area of review of the wells listed in the well data tabulation that penetrate the
proposed injection zone;
See attached Figures 2, 3 & 17.
(D) potentiometric surface map(s) that show the direction of groundwater movement, existing and proposed wells;
See attached Figures 5 & 6.
(E) contaminant plume map(s) with isoconcentration lines that show the horizontal extent of the contaminant plume in soil and
groundwater, and existing and proposed wells;
See attached Figures 7 through 16.
(F) 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, major changes in lithology, and existing and proposed wells;
See attached Figures 7 through 16.
In -Situ Groundwater Remediation Application Rev. 8-28-2017 Page 10 of 12

(G) any existing sources of potential or known groundwater contamination, including waste storage, treatment, or disposal
systems within the area of review of the injection well or well system.
See attached Figure 3 for the location of former and current asphalt testing labs (ATL) and above
ground fuel storage tanks (AST). The former asphalt testing laboratory has been gone for over
30 years. Past investigations found no soil contamination consistent with an ongoing source of
contamination. Residual groundwater contamination is the only known continuing source at the
site to feed the plume.

All concentrations shown are expressed in micrograms per lite (ug/L), which is equivalent to parts per bill on (ppb).
GCL = gross contaminant levels Gold = Concentrations above Detectable Limits Shaded = Concentrabons above 2L Groundwater Standards NSE = No Standard Established
11,1-Dichloroethylene (vinylidene chloride, or 1,1 DCE ) was adopted by the Environmental Management Commision in accordance with 15A NCAC 02L .0202 (f) at 350 ug/L and is above the federal MCI.. Where a private drinking water well or public water system is Impacted by 1,1 DCE, the applicable standard is 7 ug/L, in accordance with 15A NCAC 02L .0202.
E = Estimated concentration above the calibration range 3 = Detected but below the Reporing Limit, therefore, the result is an estimated concentration
