COMMENT 3
Based upon the relatively high groundwater concentrations of PCE and information provided by IT
Corporation regarding the amount of PCE in the soils near the AST, there seems to be potential for free
product to exist in the subsurface. Therefore, submit a proposal describing your plans to determine if free
product is present and how you intend to deal with it. - The plan should explain any side effects that such
free product will have on the injection process, specify how much heat will be produced from the oxidation
of such free product and indicate specifically how you plan to safely dissipate excess energy generated.
RESPONSE
Free product, if present, will have minimal impact on the injection process. Permanganate is much more
stable than hydrogen peroxide and does not degrade as rapidly, even in the presence of free product.
The reaction of permanganate with free product generates COZ, a non-flammable gas over a period of
days. The sections below describe IT's efforts to delineate free product, the heat that would be expected
to be generated if free product were encountered during injection, and how this heat will be dissipated.
Free Product Delineation
IT Corporation has already made extensive efforts to delineate the extent of free product at this site.
These efforts have included collection of soil samples and screening of soils from the installation of 12 soil
vapor monitoring points in the source area adjacent to the Perc AST in December 1998, and gauging of all
site monitoring wells for LNAPL and DNAPLs in January 1999. More recently in,September 1999, IT
Corporation performed a geoprobe investigation in the area of the former gasoline UST and Perc AST to
delineate the extent of free product. In addition, two bedrock monitoring wells were installed in the source
area on the Ballard property in October 1999. One of these wells was cored to a total depth of 153 feet.
These wells, along with all other on -site wells (total of 39 wells) were gauged for free product (LNAPL and
DNAPL) during the week of October 26, 1999. To date, no free product has been detected at this site
during any of these activities. These efforts to delineate free product will be described in detail in the CSA
Addendum that will be submitted to NCDENR in December 1999.
Because free product will have minimal impact on the injection process, additional delineation beyond
what has already been performed is not necessary and is therefore not being proposed at this time.

Heat Generation from Oxidation of Free Product
Calculations
IT's most aggressive injection design is to introduce 25 gallons of a 15% sodium permanganate solution
per 5-foot depth with a 10-foot radius of influence. With this injection and a soil porosity of 30%, the
average permanganate concentration in the groundwater in the zone of influence will be about 1 gram per
liter. (See calculations in Appendix A) From the thermodynamics of permanganate oxidation of PCE, 233
kcal of heat will be released per mole of PCE reacted, and nearly 180 liters of permanganate treated
groundwater will be required to react with each mole of PCE.. Based on this calculation, contact with
DNAPL (PCE) will produce an average temperature rise of less than 2 degrees C in the treatment/reaction
zone. (See calculations in Appendix A). Temperature increases of this magnitude have been observed at
other sites where we have applied in situ oxidation with permanganate
The theoretical maximum scenario for heat release is direct contact of 15% permanganate solution,
without groundwater dilution, with free product PCE in the subsurface. In this case, if an immediate and
complete reaction is assumed and there is no heat dissipation to surrounding environment, the
temperature increase of the involved soil/groundwater would be about 70 degrees C. Resultantly, the
maximum temperature achievable in this hypothetical scenario is 90 to 95 degrees C. In reality, this
temperature will not be approached because dilution of the permanganate reagent must occur to come in
contact with any free product PCE. Additionally, the reaction rates observed for PCE oxidation in bench -
scale soil column testing are over a period 24 to 48 hour period and these tests have not observed any
significant heat of reaction. Based on this information, IT concludes that the subsurface matrix will safely
absorb the small quantities of energy generated from permanganate oxidation.
IT's Experience at Other Sites
To address this issue further, we have reviewed several other permanganate applications we have
conducted to provide actual site data on this type of issue. This past summer at a site in New Jersey we
conducted a pilot test using sodium permanganate. We applied 350 gallons of permanganate in a 20%
solution to treat an area that was contaminated with Toluene, Benzene and Propanol. Prior to .the
application of the permanganate, separate phase LNAPL was detected in the monitoring well. We
proceeded with the testing and monitored for temperature changes. The maximum change in the
monitoring wells in that area was less than five degrees centigrade. This data we believe is a good

demonstration that permanganate treatment does not pose a risk since it does not generate significant
heat in its reaction.
Site -Specific Data
Finally, IT is proposing to conduct a pilot test, as described in the enclosed pilot test work plan (Appendix
D) to provide site -specific data on heat generation. Phase 1 of the pilot test will be conducted in the
unpaved area where the source of the release was formerly located. If free product were present at the
site, it would be encountered in this area. The pilot test design includes monitoring before during and after
the test for changes in temperature in soil and groundwater using existing soil vapor and groundwater
monitoring wells. Based on previous experience, increases in temperature during or after injection are not
expected to exceed 10 degrees C. If, during the pilot test, increases in temperature over baseline levels
of greater than 20 degrees C are observed, the application of permanganate will be temporarily halted
until temperatures stabilize to within 5 degrees of pretest levels.
COMMENT 4
Since this AST was the source of the PCE contamination, you will have to demonstrate that the AST is no
longer leaking PCE into the environment.
RESPONSE 4
The AST was taken out of service in July 1999 and removed from the site. The facility is not currently
being used to dispense PCE.

RESPONSE
The volume of sodium permanganate to be injected and the associated radii of influence estimated for
treatment zones I, II and III were calculated as a function of:
,I • Total volume of unsaturated and saturated media present in each zone;
• the interpolated average adsorbed and dissolved phase chlorinated solvent concentrations present in
each zone;
• the stochiometric relationship between pounds of permanganate required per pound of total VOCs, as
determined by bench scale tests conducted in February 1999
• the rate of natural consumption of permanganate through reaction with other oxidizable species
present in the residual soils throughout the site; and
• The actual area available for injection based on site constraints (topography, structures, etc.)
io Reasonable application rates using a geoprobe rig based on a pilot application test conducted at the
site on April 1999 using clean water.
Based on historical laboratory analytical data for both soil and groundwater, general geotechnical soil
parameters (density and porosity) and the average depth to water, the total mass of adsorbed and
dissolved phase PCE were determined for both the vadose and saturated areas of each treatment zone.
Based on the results of the bench scale treatability tests, the approximate natural permanganate
consumption rate by the residual site soils was estimated. Using a 6X-stochiometric relationship, as
determined by the bench scale treatability tests, the total required volume of sodium permanganate was
calculated to react completely with the chlorinated solvents and overcome the natural soil consumption.
Once the estimated mass of sodium permanganate required to treat the PCE was determined, the radii of
influence were calculated. The radii of influence are based on: the quantity of sodium permanganate
solution required; the surface area available for application based on natural and man-made site
i
constraints; and a reasonable volume of permanganate solution to be injected in each boring (as
confirmed by the pilot injection test conducted in April 1999). Due to the presence of higher dissolved and
adsorbed phase chlorinated solvent concentrations in the immediate vicinity of the former AST, a smaller
radius of influence was selected to reduce the gallons of permanganate solution required to be injected in
each boring. The required volume to be injected in each 5-foot interval in the various treatment zones
ranges from 12 to 25 gallons in zones 1 and 3, respectively. The 25-gallon volume requested in the UIC
application for each zone was used as a maximum, as determined in the calculation for zone 3.

Based on these calculations, the volume of permanganate should be sufficient to oxidize the chlorinated
ethenes present throughout the zone of influence. However, these calculations will be confirmed prior to
full-scale injection, by the performance of a pilot test. The work plan for the pilot test in included in
Appendix D.
COMMENT 8
The proposed injection volume of 25 gallons per 5 vertical feet used in the injection process was not
completely achieved in the pilot study. Please submit an explanation of your expectation to achieve the
proposed volume at this site.
RESPONSE
The 25-gallon volume was achieved during the injection test on boring ITP-2. The 25-gallon volume was
injected in 15 minutes at the maximum depth. At the next two injection intervals, we injected 23 and 24
gallons respectively in the 15-minute interval. After proving that we could inject the 25 gallons, it was
- unnecessary to continue to inject that volume all the way to the surface. We simply injected a smaller
volume and monitored the delivery time and pressures so that we could extrapolate an injection time for
the complete 25 gallons: Based on the pilot injection test, we expect to be able to achieve the proposed
injection volume without any problems.
COMMENT 9
During the injection process, what specific measures or hydraulic control will be used to prevent migration
of both the chlorinated and petroleum hydrocarbons into areas where the groundwater is not
contaminated?
RESPONSE
Hydraulic control is not proposed during permanganate application because the process will not cause
migration of chlorinated and petroleum hydrocarbons into areas where groundwater is not contaminated.
i Migration will be prevented by the very small relative injection volume, the site geology and site
hydrogeology. Two sets of calculations that form the basis for this conclusion are presented below. Also,

as described in the attached pilot study work plan (Appendix D), groundwater monitoring will be
performed before, during and after the proposed pilot injection event to confirm that the injection process
does not cause migration of contaminants into areas where groundwater is not contaminated.
Calculations Based on Volume Displacement
During the permanganate application, approximately 25-gallons of oxidant will be injected at five-foot
depth intervals in each boring. The borings will be laid out in either 10-feet or 20-feet radii. The volume of
liquid being displaced by the addition of 25 gallons in a 10-foot radius over a 5- foot height of saturation
can be easily calculated. A cylinder of saturated soil with a 10-foot radius, a height of 5 feet, and a
porosity of .30 and contains a volume of groundwater of approximately 471.42 cubic feet or 3526.3
gallons. The addition of 25 gallons of water to this cylinder represents an addition of less than 1 % of the
total volume. The addition of this same volume of water to a 20-foot radius cylinder represents an addition
of less than 0.5% by volume.
If 25 gallons were added to the cylinder containing 3526.3 gallons, the total gallons contained would be
3551.3 gallons. If all of this increase were absorbed laterally, the new theoretical radius of the cylinder
would be 10.035 feet, an increase of 0.035 feet (0.42 inches). If all of this increase were absorbed
vertically, the new theoretical height of the cylinder would be 5.035 feet, an increase of 0.035 feet (0.42
inches). As these calculations demonstrate, the hydraulic displacement caused by the injection of this
limited volume is so small (less than half an inch) as to be negligible.
Calculations Based on Hydrogeology
During the permanganate. application, approximately 25-gallons of oxidant will be injected at five-foot
depth intervals in each boring. From our injection test, the total injection time at each injection interval for
25 gallons is approximately 15 minutes. Based on calculations for mounding, the expected mounding
effect at a distance of 1 foot from the injection point for injecting 25 gallons of a liquid with a density similar
to that of water over a 15 minute period is 0.799 feet. To carry this one step farther, the expected
mounding effect at a distance of 1 foot from the injection point after injecting 300 gallons was calculated.
Assuming an injection rate of 1.66 gpm (calculated by injecting 300 gallons over the estimated injection
time interval at each injection point of 180 minutes) the total mounding effect at each point is expected to
be 1.38 feet. It should be noted that the latter calculation assumes a worst case condition of injecting 300
gallons continuously over a 180-minute time interval. Our injection procedure will not be continuous. In

fact, the actual injection period will be longer due to the time required to reposition down -hole equipment
and set-up/break-down time at each injection interval. This longer period will allow for greater time for
head equilibration between injection intervals, which should result in a lower actual mounding effect.
Examination of distance and time-drawdown curves generated during aquifer testing indicates that the
unconsolidated sediments are highly stratified. Stratification due to differential weathering and mineral
composition would be expected in a saprolitic formation. As such, the vertical hydraulic conductivity is
estimated to be 0.5 times that of the horizontal hydraulic conductivity. Therefore, it is likely that minimal
increases in head pressure, as will be associated with the injection events, will be primarily distributed
horizontally through the aquifer unit; especially along zones of higher hydraulic conductivity within the
saturated zone.
In conclusion, the application of permanganate by the method we have proposed will result in minimal,
short term, mounding effects (and therefore minimal, short-term increases in hydraulic head) at each
injection point. Therefore, it is concluded that the injection process will not result in the unwanted
migration of contaminants, either vertically or horizontally.
COMMENT 10
On page 2 of the injection well permit application, IT Corporation provided equations that represent the
oxidation of PCE, TCE and DCE with sodium permanganate. These equations show that copious
amounts of the by-product carbon dioxide (CO2) gas will be produced under an area where roughly 90% of
the surface is covered with asphalt and concrete. Such a situation raises concerns regarding the possible
migration of CO. into human breathing spaces. Potential by-products of the oxidation of chlorinated
hydrocarbons are chlorine gas (CL2), hydrochloric acid and carbonic acid. The two acid by-products could
make the groundwater extremely acidic, while the CL2 could also migrate into human breathing spaces.
You need to address these concerns and also answer the following questions: "How will CO2, CL2,
hydrochloric acid and carbonic acid affect the injection processes at this site?" "How will the migration of
any by-products be controlled?"

RESPONSE 10
The products of DCE, TCE and PCE oxidation with permanganate are CO2, HCI, NaCl, Mn02and -OH.
No chlorine gas will be generated from the reactions and, in IT's experience with permanganate
treatments, no chlorine gas has ever been detected.
Calculations
Carbon dioxide is a harmless non-flammable gas produced at a rate of two moles for each mole of organic
compound that is oxidized. Venting of the gas from the subsurface 'during treatment to human breathing
spaces will not be of concern as long as the spaces are provided with normal ventilation. Using the
injection as described in response to comment no. 3, 180 L of permanganate treated groundwater will be
involved in oxidation of each mole of PCE. This volume of solution is sufficient to dissolve the CO2
produced from reaction, as the solubility of CO2 in water is 1.7 gram per liter at atmospheric pressure.
This allows the controlled release of gas as CO2 diffuses to the surface. In areas close to the injection
point, the permanganate concentration will be higher and the volume of solution may not be sufficient to
dissolve all of the CO2 eventually produced from reaction, but even in these areas no pressure buildup is
expected. The bench -scale tests have shown that the oxidation of PCE will take place over several days
to two weeks and will allow sufficient time for release of the CO2withoutpressure concerns.
IT's Experience
In IT's experience, generation of HCI from oxidation of chlorinated organic compounds has not
significantly altered the groundwater pH. This is due in part to the natural buffering capacity of the soil that
neutralizes the acid produced. It is also due in part to competing permanganate oxidation of soil
constituents that consume acid and balance the acid production from reactions with chlorinated organics.
The competing reactions are both inorganic in nature (such as oxidation of iron (Fe+2) species) and
organic in nature (such as oxidation of humic material.)
The rate of production of CO2 and HCI will be limited by the relatively slow rate of reaction, which will
spread the production over several days at a minimum. In this time, CO2 will be released to the surface in
a safe manner through a moderate pressure gradient to the surface and subsurface equilibrium between
I!
gas phase CO2, and dissolved phases of CO2, bicarbonate and carbonate species. Also, in this time,

other processes involving soil constituents, including oxidation by permanganate and neutralization will
consume HCL.
Site -Specific Data
To provide site -specific information on the generation and migration of reaction byproducts, a pilot study is
proposed. The work plan for the study is included in Appendix D. During the pilot study, the key
parameters of concern will be monitored and the results will be evaluated prior to full-scale
implementation.
COMMENT 11
IT Corporation submitted the EPA's In Situ Remediation Technology: In Situ Chemical Oxidation,
Innovation Technology Report dated September 1998. The Groundwater Section's staff has reviewed this
report and noted that most In Situ Chemical Oxidation systems are designed in conjunction with a pump
and treat and/or soil vapor extraction system to remove the remaining by-products from the injection
process. You will need to answer the question "Why has a groundwater and/or soil extraction system not
been proposed for this site during the injection process?" The Groundwater Section's staff also believes
that a pilot study should be conducted to verify that this injection process will successfully oxidize the
chlorinated hydrocarbons without harmful environmental effects.
RESPONSE 11
The paper that EPA prepared on the use of permanganate discussed a number of sites that had already
had some form of remediation system (usually groundwater extraction, soil venting and sometimes
sparging) already in place from prior remedial efforts. In almost all cases, the remediation systems were
temporarily stopped in the vicinity of the permanganate treatment. This was done to avoid the potential to
have accelerated groundwater movement toward a groundwater extraction point. This accelerated
movement would not allow for optimum dispersion of the permanganate from the point of addition. This
would be detrimental for oxidation treatment since it would result in increased travel distances but not
allow for treatment over any significant lateral area. For this reason, we do not apply this oxidation
technology with other groundwater extraction except where a key receptor (i.e. stream other surface water
body) required protection.

The application of permanganate is the first phase of a multiphase, multi -technology remedial approach at
�_J this site. The second phase is the installation of a high vacuum dual phase system (HVDP) to remediate
any recalcitrant volatile organics that are not addressed by the permanganate. This approach is described
_) in the CAP that was submitted to NCDENR on May 21, 1999. The primary remedial objective at this site
r,
is to achieve 90% reductions in Total VOCs in the shallow groundwater plume (less than 65' below ground
surface) as measured in a network of 21 monitoring wells at the site. The timetable to achieve this
reduction goal is by March 2003. IT Corporation believes that achieving this goal will require more than a
r single remedial technology. One of the major reasons for applying the permanganate prior to installation
of the HVDP system is to get the oxidizer into the subsurface to reduce contaminant concentrations in
groundwater while the HVDP system is being designed, perrr)itted and installed. This approach will make
the most use of the limited time before the March 2003 goal. Another major reason is that, if the
permanganate application is as successful as we believe it will be, then the HVDP system in phase 2 may
I�
} be smaller and less disruptive to commercial site redevelopment/reuse than the extensive system that
would be required to remediate the current plume.
Because migration of permanganate and products of the reaction are limited by the site geology,
hydrogeology and the nature and volume of permanganate applied, hydraulic and vapor control are
i,
neither necessary nor particularly beneficial (as described above). This is a one-time application of a
limited volume of oxidizer (approximately 300 gallons per injection point). The oxidation reaction is fairly
localized around each geoprobe point (hence the need for over 200 geoprobe points).
In order to verify for NCDENR that the injection process will successfully oxidize the chlorinated
hydrocarbons without harmful environmental effects, IT Corporation proposes to perform a pilot study as
the first phase of a multi -phased implementation program. As shown on the attached phasing plan,
Appendix E, the first phase will consist of approximately 12 points, the second phase will be
approximately 12 points and the final phase (full-scale) will be approximately 175 points. The results from
the first and second phases will be evaluated and used to make adjustments to the calculated injection
rates and injection point spacing, (based on actual field data), for the full scale.
A work plan for the pilot study is attached as Appendix D. The pilot study is proposed to consist 2
phases. In the first phase, 12 injection points installed on the former Ballard property in an unpaved area.
The advantages of performing the Phase 1 pilot test in this area are:
• the area is unpaved so concerns about pressure buildup under pavement should not be an issue;

• 12 soil vapor monitoring points installed in this area can be used to monitor for potential gas pressure
increases and heat generation in the subsurface, and;
• 7 monitoring wells in this area can be used to monitor the progress, effectiveness and byproducts of
the process in groundwater.
After the completion of the first phase, the monitoring data will be evaluated and a second phase of the
pilot will performed consisting of 12 injection points installed in the paved area on the former SLS property.
The target area for the Phase 2 pilot is an area where previous aquifer testing was conducted and an
extensive network of deep and shallow groundwater monitoring wells have been installed.
Once the two phases of the pilot test have been completed and post-test monitoring has been performed,
a Pilot Test Report will be prepared and submitted to NCDENR for review. Pending the results of the pilot,
the Pilot Test Report will include a request for approval for full-scale implementation.
COMMENT 12
The monitor schedule needs to be more specific or detailed and include both pre- and post- injection
monitoring. Pre -injection samples will provide background concentrations that can then be compared with
post -injection concentrations to determine the system efficiency and effectiveness.
RESPONSE 12
A specific monitoring schedule for the pilot test is included in the attached work plan in Appendix D. This
schedule includes a detailed plan for both pre- and post — injection monitoring. A similar monitoring
schedule will be followed during subsequent phases.

Conc. of NaMn04 in subsurface = 15% x 25 gal/3,525 gal = 0.1064% = 1.064 g/L of solution
Volume of water involved in reaction of one mole of PCE:
1 mole PCE reacts with 4/3 mole NaMn04 (stoichiometry) = 4/3 x 142 g/mole = 189 g NaMn04
Volume of subsurface water containing 189 g NaMn04 = 189 g / 1.064 g/L solution = 178 L
Water involved in reaction with one mole PCE = 178 L x 1,000 g/L / 18 g/mole = 9,886 moles
Temperature rise (delta T) due to reaction of one mole of PCE (233 kcal):
Heat release = H2O heat cap. x moles H2O x delta T + PCE heat cap. x moles PCE x delta T
Delta T = heat release / (1120 heat cap. x moles H2O + PCE heat cap. x moles PCE)
Delta T (°K) = 233 kcal / (.018 kcal/OK-mole x 9,886 moles + .025 kcal/°K•mole x 1 mole
Delta T = 1.3 °K or °C or 2.4'T

SOLUBILITY OF CARBON DIOXIDE
4NaMnO4 + 3C2CI4 + 4H20 4 4MnO2 + 6CO2 + 12CI" + 4Na+ + 8H+
Carbon dioxide (CO2) MW = 44 g/mole
Carbon dioxide produced in molar reaction:
i
CO2 produced in reaction of one mole of PCE stoichiome ( try) = 2 moles COZ
Weight of CO2 produced (g) = 2 moles x 44 g/mole = 88 g
Carbon dioxide solubility:
Subsurface water involved in reaction of one mole of PCE = 178 L
Solubility of CO2 at atmospheric pressure = 1.7 g/L
Weight of CO2 required to reach water saturation = 178 L x 1.7 g/L = 303 g
88 grams of CO2 will be produced per mole PCE reacted.
303 grams of CO2 solubility capacity in the water involved per mole of PCE reacted.
Sufficient solubility to dissolve CO2 produced.
