ATTACHMENTS

ATTACHMENT A - SITE HISTORY
1) Site Usage
Site ST-Q8, situated in a highly industrialized area near the center of the base between Taxiway
B and Boxcar Street, and adjacent to Tank Creek, consists of former Building 41105. The Site
was historically used as a No.2 fuel oil storage and distribution center for the base. Fuel oil was
delivered to the Site by tanker trucks and rail cars, where it was unloaded and stored in four
25,000 gallon underground storage tanks (USTs). Presently there are no buildings or structures
on the ground surface or subsurface in the vicinity of the former fuel storage facility.
2) Origin of the Contamination
The facility was in operation from 1954 to 1985. As part of a base wide UST evaluation program
the USTs were precision tested in 1990. One of the tanks failed precision testing. In November
1992, the four tanks, ancillary piping, and fuel dispensers were excavated and removed. During
excavation, soil contamination was encountered and free product was observed on water that
collected in the open excavation. Contaminated soil was used to backfrll the excavation on top of
a plastic liner after the tanks were removed. A Site map, provided in Attachment H, illustrates
the former UST locations as well as the initial soil and groundwater sampling locations.
3) Previous Remedial Actions
The original remediation approach at the Site involved the use of air sparging to address the
presence of LNAPL and reduce the dissolved phase constituents of concern (COCs) in
groundwater. However, operation of the air sparging system was suspended in June 2010 due to
decreased effectiveness. The current remediation approach at the Site involves gauging of all
monitoring (temporary and recovery) wells and the use of aggressive fluid vapor recovery
(AFVR), oleophilic socks, and passive skimmers for the removal of LNAPL.

ATTACHMENT B - HYDROGEOLOGIC DESCRIPTION
1) Regional Geologic Setting
The Site is located in the Atlantic Coastal Plain Physiographic Province of eastern North
Carolina. The Coastal Plain consists of an eastward -thickening wedge of Cretaceous to
Holocene sediments, comprised of layers of fluvial and marine sands, silts, and clays.
According to the North Carolina Geologic Survey's Geologic Map of North Carolina 1985,
Cumberland County is primarily underlain by the Cape Fear, Middendorf, and Black Creek
formations of Cretaceous age. These formations consist of sandy clays, clayey sands, silts, and
mudstone.
2) Significant Changes in Lithology
The lithology at the Site is relatively consistent within and surrounding the area of
contamination.
3) Aquifer Properties (Hydraulic Conductivity, Transmissivity, and Specific
Yield of the Aquifer to be Used for Injection and Tests Used to Determine
These Parameters)
To date no specific aquifer characteristic testing has been performed at Site ST008. However,
numerous aquifer capacity tests were performed at an adjacent site (i.e., 1200 feet to the east),
Site SS007, and URS believes the lithology at SS007 is very similar if not the same as at ST008.
Hydraulic conductivity (K) was calculated from rising -head slug tests and confirmed by
laboratory geotechnical analysis (URS, 2001). Transmissivity (T) was calculated from a step-
drawdown test using a saturated aquifer thickness of 22 feet (URS, 2001).
Hydraulic conductivity (K): 0.5 — 82.3 ft/day (average of 29 ft/day)
Transmissivity (T): 460 ft2/day estimated
Specific Yield (Sy): 0.20 — 0.30
Hydraulic conductivity (K) was calculated for soils comprising the surficial aquifer based on the
monitoring well slug tests using the Bower and Rice unconfined aquifer slug test method (Bower
and Rice, 1976). A K value from a step drawdown test closely approximated slug test results.
Specific yield (Sy) for the surficial aquifer was estimated based on published typical values for
silty to sandy sediments (McWhorter and Sunada, 1981).
4) Depth to the Mean Seasonal High Water Table
The mean seasonal high water table at the Site (as indicated by measurements from the wells that
are the focus of the injection event) ranges from approximately 11 to 16 feet below ground
surface.

ATTACHMENT C - INJECTION FLUID COMPOSITION
BOS 200® Composition and Characteristics
BOS 200® is composed of a specially -formulated blend of activated carbon, sulfate reduction
media, micronutrients, and facultative microbes. When the product is used, a proprietary mixture
of naturally occurring microbes (Trap & Treat® Bacteria Concentrate) is added to speed up the
remediation process.
Potentially hazardous components of BOS 200® include the activated carbon and calcium sulfate
(gypsum) mixture, which is an odorless black powder with NFPA Ratings of zero for health and
reactivity, and one for flammability. The material decomposes at 1450°C. Contact with strong
oxidizers, such as ozone, liquid oxygen, chlorine, etc., may result in fire.
Routes of entry include inhalation, skin absorption, and ingestion. The material may produce
eye irritation if exposed to dusting conditions without protective eye equipment; it is not a
primary skin irritant and is non -toxic through inhalation and ingestion. The effects of long-term,
low-level exposures to carbon have not been determined. The material, when wet, removes
oxygen from air.
Trap & Treat® Bacteria Concentrate Composition and Characteristics
Trap & Treat® Bacteria Concentrate is composed of a tan to flesh -colored liquid blend of
naturally occurring bacteria and fungi with an odor similar to sour milk. According to the MSDS
for the material, none of the ingredients have been found to be hazardous under OSHA's Hazard
Communication Rule, 29 CFR.1910.1200. The material may cause irritation to skin and eyes.
Fire, explosion, and reactivity information for this material indicate no flash point and no
incompatibilities.

ATTACHMENT D - INJECTION RATIONALE
1) Current LNAPL recovery techniques and methodologies have exhibited reduced efficiency over
the past six months. The goal of the injection of BOS 200® at Site ST008 is to address light non -
aqueous phase liquid present in monitoring wells MW8-19 and MW-HF1.
2) The proposed injectant volumes and concentrations were determined by AST Environmental, Inc.
through a review of historical LNAPL thickness, depths, and distribution.
3) The LNAPL at the Site is expected to react with the injectant by adsorption "trapping" and then
biologically breaking down to carbon dioxide and methane through both aerobic and anaerobic
bio-degradation "treating". This is a proprietary treatment mechanism that adsorbs the
contaminant into the carbon matrix and allows attached growth microbes to biologically break
down the contaminant, releasing either carbon dioxide or methane. Once this conversion is
completed, the CO2 and methane move outside of the Carbon matrix leaving additional room for
more of the hydrocarbons.
See attached proposal for calculation of injectant masses.

ATTACHMENT E - INJECTION PROCEDURE & EQUIPMENT
1) URS proposes to inject the BOS200® as a field prepared slurry (see attached map in Attachment
H). The treatment area is approximately 2,400 square feet with the advancement of an estimated
32 borings within the area. Spacing of the points will be in grid pattern (i.e., offset rows with
approximately 7.5 foot spacing between each point). Borings are to be advanced between
approximately 11.5 and 16.0 feet below ground surface (ft bgs). A direct push technology (DPT)
drill rig will be used as a delivery platform. A "top down" injection method will be utilized in
which BOS200® is injected one foot at a time between approximately 11.5 feet bgs and 16.0 feet
bgs (injection intervals may change based on conditions observed in the field). An injection
manifold inclusive of quick connect couplings, a ball valve, and a pressure gauge will be attached
to the top of the DPT rods. Concurrent with the DPT advancement, The BOS200® liquid slurry
will be mixed together and continue to be mixed during the injection events. The injection
system will be a contractor supplied temporary mobile system. General components consist of a
mixing tank, product pump, metering and measuring system and affiliated conveyance hose. The
application apparatus will include an injection pump with controller able to modulate flow to
below five gallons per minute (gpm). The injection pressure will be monitored at the injection
manifold through pressure gauges.
2) The mobile system will be equipped with tanks for mixing the injection solution. Municipal
water will be used for the solution mixing. The solution will be injected at ambient temperatures.
High pressure hose will extend from the mixing tank, to the injection pump, to the injection. A
pressure gauge, shut-off valves, and pressure bleed -off will also be installed in -line. Injection
will be performed using a diaphragm pump. Injection pressures may range from 400 to 700
pounds per square inch (psi) and injection flow rates are estimated to be approximately 35 gpm
per injection point. The injection pressure will be monitored continuously using a pressure gauge
and the injection rate will be adjusted using the injection pump and valves. After injection, the
injection pump will be turned off and the shut-off valve will be closed.
3) Detailed diagrams of the surface and subsurface portions of the system are provided in the
attached figures.
4) It is anticipated that the injections will take place in fall 2011, pending Underground Injection
Control (UIC) permit approval by the North Carolina Department of Environment and Natural
Resources (NCDENR). URS anticipates the injection event at Site ST008 will take 1-2 days.

ATTACHMENT F - MONITORING PLAN
1) List of existing monitoring wells to be used for sampling:
MW8-I MW8-08, MW8-09, MW8-11, MW-13. MW8-18, W8-19, MW-HF1,
MW8-1
2) List of monitorin _ parers and analytical methods to be used:
• LNAPL thickness in all Site wells
• Volatile aromatics (EPA Method 602), semi volatile compounds (EPA Method 625),
extractable petroleum hydrocarbons (EPH) and volatile petroleum hydrocarbons
(VPH) will be collected prior to the injection event and approximately 1 year after
completion of the event. This will be performed in conjunction with Site performance
monitoring.
• Sulfate, Sulfite, Nitrate and Nitrite
3) Schedule for gauging/sampling to monitor the proposed injection:
LNAPL thickness will be measured in all Site wells prior to the injection event, 1 day after the
event, 1 week after the injection event, 2 weeks after the injection event, and the approximately
monthly for the next year.
Sulfate, Sulfite, Nitrate and Nitrite will be collected in the wells specified above prior to the
injection event, approximately 3 months after the injection event, 6 months after the injection
event and after approximately 1 year.

RE: Proposal for BOS 200® Injection at Pope Air Force Base — Site ST008
Fayetteville, Cumberland County, North Carolina
Dear Mr. Kucera,
AST Environmental, Inc. (AST) appreciates the opportunity to provide this proposal for the
above referenced site. This letter proposal presents the remedial approach and cost to inject
BOS 200® to address light non -aqueous phase liquid (LNAPL) present in monitoring wells
MW8-19 and MW-HF1 at Site ST008. AST is also providing a cost to conduct a BOS 200® pilot
test in the area of TW19-06 at Site SS019. The pilot test will be conducted during the same
mobilization as the ST008 injections. The cleanup goal is to remove LNAPL from the wells.
ST008 Injection Design
During the December 2010 groundwater monitoring event, LNAPL was detected in monitoring
wells MW8-19 and MW-HF1 at 0.11 and 0.29 feet thick, respectively. The injection design
addresses the two wells separately with a 900 s.f. treatment area centered around each well.
A targeted injection grid will be completed around each well. The grid spacing corresponds to a
conventional 7.5-foot triangular grid. The injections are designed to achieve a 7.5' effective
radius of influence (ROI) and straddle across the assumed smear zone. The smear zone is
based on historical depth to product readings obtain from each well. The assumed smear zone
in each treatment area is: MW8-19 from 13.5-feet to 16-feet below ground surface (bgs) and
MW-HF1 from 11.00-feet to 13.00-feet bgs. The smear zone will be verified in each treatment
area prior to injection by completing a soil boring adjacent to each well. The soil from the
borings will be screened using a PID and visually inspected to identify free product or highly
impacted soil.
Injections will be completed every 1- vertical feet across the smear zone with adjacent injection
points staggered in order to increase efficiency by creating some overlap between injections.
The following summarizes the injection plan.
MW8-19 Treatment Area
• 900 square feet
• Free phase petroleum, 0.11 feet
• 16 injection points
• 48 injections : alternating depths beginning: (13.5', 14.5', 15.5' and 14.0', 15.0', 16.0')
• Injection — 30 Ibs/injection = 1,440 Ibs of BOS 200®, 5 gallons bacteria concentrate,
—900 gallons of water

Mr. Jonathan J. Kucera

MW-HF1 Treatment Area
• 900 square feet
• Free phase petroleum, 0.29 feet
• 16 injection points
• 32 injections : alternating depths beginning: (11.5', 12.5' and 12.0', 13.0')
• Injection — 60 lbs/injection = 1,920 lbs of BOS 200®, 5 gallons bacteria concentrate,
—900 gallons of water
ST019 Pilot Test Injection Design
AST is proposing to complete a BOS 200® pilot test in an approximate 575 square foot area
around TW19-12 and RW19-02. The pilot test will be conducted during the same mobilization
for the ST008 injections. The goal of the pilot test is to demonstrate the performance of the
BOS 200® to eliminate the large volume (0.52 feet, TW19-12 and 0.44 feet, RW19-02) of free
product in the wells by allowing the biological process to optimize the cleanup efficiency. The
area will be purposely under dosed to demonstrate the effects of the biological treatment.
A targeted injection grid will be completed around the well. The grid spacing corresponds to a
conventional 7.5-foot triangular grid. The injections are designed to achieve a 7.5' effective
radius of influence (ROI) and straddle across the assumed smear zone. The top of the smear
zone is based on historical depth to product levels in the wells and the bottom based on depth
to water levels. The assumed smear zone in: the treatment area is from 17.50-feet to 19.50-feet
below ground surface (bgs).
The treatment area will be injected with the maximum slurry density per injection of 2 pounds of
BOS 200® to 1 gallon of water. The maximum slurry density injected into the smear zone will
provide approximately half the volume of BOS 200® required to remove the estimated volume
of free product present in the wells based on carbon adsorption calculations.
Injections will be completed every 1- vertical foot across the smear zone with adjacent injection
points staggered in order to increase efficiency by creating some overlap between injections.
The following summarizes the injection plan.
ST019 Pilot Area
• 575 square feet
• Free phase petroleum
• 10 injection points
• 25 injections : alternating depths beginning: (17.5', 18.5', 19.5' and 18', 19')
• Injection — 60 Ibs/injection = 1,500 Ibs of BOS 200®, 5 gallons bacteria concentrate,
—750 gallons of water
Monitoring Well Installation
At the direction of URS, AST will install a new monitoring well at the site. The well will be
installed to 35 feet with 10 feet of well screen. The well will be completed at the surface with a
flush mounted 12-inch well can installed in a 2-foot by 2-foot concrete well pad.
Assumptions
AST has made the following assumptions regarding this approach:

Mr. Jonathan J. Kucera '.E.

Page 3
1. The injection permit (UIC permit) for the site will be acquired by others.
2. There will be adequate water onsite (75-gpm service) to prepare the BOS materials for
injection. AST will provide a water truck to shuttle water. The water will be provided at
no cost to AST. Hydrant permits and fees will be provided by others.
3. The site stratigraphy allows for pushing up to 300 If of 1.25 geoprobe rods per day using
7720 probe. The site stratigraphy will allow for the injection of the up to 1700 Ibs of BOS
200® per day.
4. All utilities and underground appurtenances will be located prior to AST arriving onsite.
AST has not included any provisions to perform subsurface utility clearance (such as
hang auger boreholes). This can be provided by AST for an additional cost. AST will
not be responsible for repairs to mismarked or unmarked buried utilities and other
appurtenances.
5. Any boring logs will be prepared by others.
6. Work hours are between 7:00 a.m. and 5:00 p.m.
