1. Injection Zone
The former Salem Uniform facility (Site) located at 4015 North Cherry Street in Winston-Salem, North Carolina. The
Site is located at the southeast intersection of North Cherry Street and Polo Street in Winston-Salem, Forsyth County,
North Carolina (Figure 1).
The proposed enhanced reductive dechlorination (ERD) injection zone as stipulated in Title 15A North Carolina
Administrative Code 02C .0225(e)(2) coincides with the Area of Review that is shown in Figure 2. Source area
injections will take place in an area of approximately 36,480 square feet, generally in the area of the shallow
groundwater plume with concentrations in excess of 1,000 micrograms per liter (pg/L) in order to reduce source area
mass. Injections will be administered by direct -push technology (DPT) into the shallow aquifer targeting a 10- to 50-
foot interval at a depth of approximately 20-70 feet below ground surface (bgs). Additionally, injections will be
completed at three downgradient barriers, including one onsite barrier and one off -site barrier each completed in
partially weathered rock (PWR), and one off -site barrier completed in saprolite. Injections will occur in the PWR
barriers via permanent wells, and into the saprolite barrier via DPT. Each barrier is approximately 120 ft long.
Injections into the permanent wells will target a 30-foot interval in the PWR aquifer at a general depth of 60-90 feet
bgs. Injections in the saprolite barrier will target a 20-foot interval at a general depth of 40-60 feet bgs. Figures 3 and
4 show the proposed injection locations with April 2019 PCE data for shallow and intermediate wells, respectively.
Figures 5 and 6 are hydrogeologic cross -sections that illustrate the interpreted water table equipotential lines and
tetrachloroethene (PCE) isoconcentrations at the Site with proposed injection locations. Table 1 summarizes
proposed injection intervals and well construction details, and Appendix A includes well construction diagrams for
the proposed permanent wells.
2. Hydrogeologic Evaluation
2.1 Physiography
The Winston-Salem area is located within the western portion of the Piedmont Physiographic Province of North
Carolina. Both the regional and local landscape of the area are characterized by a broad, gently rolling uplands and
moderate to steep slopes common to the Piedmont. The drainage patterns in the area are classified as dendritic or
branching. The concave valleys are generally the result of weathering less resistant rock and soil units, which runoff
events serve as ephemeral streams. The convex areas are the result of more resistant rock, soil and direct rainfall to
the ephemeral streams. Generally, these types off drainage patterns reflect the weathering profiles, fractures, and
Iithologic contact zones of subsurface soil and rock.
2.2 Regional Geology
Geologically, the site is located in the Milton Belt litho -tectonic province of North Carolina (Brown, 1985). Bedrock in
this province is described as a metamorphic complex consisting of biotite gneiss and schist interlayered with mica,
amphibolite and granitic masses. Rocks of these compositions weather to form several distinct Iithologic zones.
Overlying the competent bedrock are unconsolidated, granular and porous materials (regolith) that may consist of
alluvial deposits, soils and residual material formed from in -situ physical and chemical weathering of the parent rock.
The portion of the regolith that is derived from weathered rock, commonly referred to as saprolite, may retain the fabric,
texture, and structures of the original bedrock but it is has the consistency of dense soil (Heath, 1989).
Saprolite represents the most extreme weathered condition of the parent bedrock from which it is derived. A transition
zone of PWR is typically found between the saprolite zone and the lower competent bedrock. PWR is typically friable
bedrock that retains the parent rock structure, but it has undergone Tess weathering than saprolite. The PWR often is
highly fractured and permeable and contains fragments of unweathered rock. Bedrock in this area typically has
decreasing fracture density with depth (Heath, 1989).

2.3 Regional Hydrogeology and Hydrology
Aquifer systems in this part of the Piedmont region correspond with the geologic units present. The saprolite is
considered an unconfined or "water table" hydrostratigraphic unit of the regional aquifer. Saprolite and PWR acts as
a storage reservoir for groundwater that feeds the underlying fractured bedrock hydrostratigraphic unit. PWR and
bedrock units can exhibit unconfined, semi -confined, or even confined hydraulics. Most water supply wells in this
region tap the fractured bedrock unit. Supply wells installed in the bedrock aquifer of this region typically yield
between 15 and 20 gallons per minute (gpm) (Daniel and Payne, 1990). In groundwater recharge areas of the
Piedmont, the water table is usually closer to the ground surface during the winter and spring months, and is typically
deeper during the drier summer and autumn months.
2.4 Site Geology
In general, subsurface soils consist of silty clay residuum overlying clayey sand and silt saprolite, which coarsens with
depth. Typically, in the Piedmont of North Carolina, the saprolite serves as an unconfined storage aquifer that
transmits water downward (generally) to the lower semi -confined PWR unit and fractured confined metacrystalline
bedrock aquifer unit (Daniel and Payne, 1990). The saprolite originates from the underlying gneissic and schistose
bedrock and typically contains relict structures and fabric derived from the parent rock from which it was weathered.
The saprolite unit is generally described as a micaceous reddish -brown to yellow -brown mottled sandy silt to clayey
silt and silty sand. The mica and quartz sand content of the saprolite varies at different locations. Thickness of the
saprolite unit ranges from 55 feet near the center of the Site to 85 feet off -site near monitoring well MW-9(i). The
saprolite generally grades into PWR with depth. PWR often exhibits the same properties as deeper saprolitic soils,
but with higher occurrence of rock and rock fragments. PWR is approximately 35 feet thick in the middle of the site
near well clusters MW-6 and MW-1, and it has a similar thickness at off -site well MW-9(i). At off -site well nests MW-3
and MW-10 the PWR is 12 feet thick or less. PWR at well MW-9(i) has alternating zones of highly weathered rock
and PWR. The zone of thick PWR observed at MW-9(i) and MW-6(d1) coincides with a possible linear trough or
depression in the bedrock surface that is highly weathered. This apparent bedrock structural feature appears to
affect the dimensions and migration of the dissolved off -site plume.
Bedrock composition varies from a dark gray, micaceous rock at to a light gray and light brown, intermediate to felsic
rock. Depth to competent bedrock is approximately 90 feet bgs at onsite bedrock monitoring well MW-6(d1) and
increases downgradient to approximately 120 feet bgs at off -site monitoring well MW-9(i) located just north of the R.J.
Reynolds Tobacco Company (RJRT) property. Depth to competent bedrock decreases rapidly toward the RJRT
southwestern property boundary with bedrock approximately 23 feet bgs at MW-15(i). Southwest of the intersection of
North Cherry Street and Reynolds Boulevard, bedrock outcrops can be observed in Silas Creek.
2.5 Site Hydrogeology
Onsite groundwater is encountered at depths ranging from 13 to 33 feet bgs and the water table surface is found
primarily in the saprolite hydrostratigraphic unit. The depth to groundwater in off -site areas ranges from 11 to 45 feet
bgs. Depth to water measurements and groundwater elevations are summarized in Table 2. Shallow and
intermediate unit groundwater potentiometric maps for the Site during April 2019 are presented on Figures 7 and 8.
Figures 5 and 6 are hydrogeologic cross -sections that illustrate the interpreted water table equipotential lines.
Potentiometric data indicate that shallow groundwater in the saprolitic hydrostratigraphic unit flows towards the south-
southeast. Potentiometric data indicate that groundwater flow in the transitional PWR aquifer is predominately
towards the south, with a slight flow component toward the southeast and southwest. Groundwater flow patterns
indicate that groundwater in both hydrostratigraphic units flows toward, and discharges into, the closest surface water
body to the Site; an unnamed tributary of Silas Creek. This tributary appears to have its headwaters along Polo Road
northeast and east of the Site, and it flows as a wet weather ditch and ephemeral stream through the wooded,
commercial Beroth Oil Company property east of the Site. South of McCanless Street the tributary has more
perennial characteristics beginning at a distance of approximately 130 feet from the southeast corner of the Site. A
portion of this stream runs through a concrete surface channel on residential properties and is then routed through
subsurface culvert pipes where it turns east to pass beneath May Street. Downstream of May Street, the unnamed
stream has open flow through the residential neighborhood south of the Site, where it then flows through a buried
culvert pipe under the RJRT manufacturing and packaging facility.

2.5.1 Aquifer Parameters
During the 2006 Comprehensive Site Assessment (ENSR, 2006) slug testing and single well pumping/recovery tests
were performed to evaluate aquifer parameters on site. Transmissivity values for MW-3(i) ranged from 4.1 ft2/day to
26.2 ft2/day. The latter value, developed from specific capacity testing, is the most reasonable value for this type of
aquifer because the zone of water contribution during pumping (assumed to be equal to the aquifer unit thickness) is
largely unknown for a single well test and a partially penetrating well screen. The range of transmissivity values at MW-
8(i) was lower (2.5 ft2/day to 12.1 ft2/day). Again, the higher value calculated from a specific capacity test is considered
more reasonable for this type of aquifer due to the unknown aquifer thickness that contributed to the yield when the
well was pumped.
The parameter of transmissivity also was estimated by using hydraulic conductivity values derived from slug tests
multiplied by the well screen length at the test well. This estimation produced transmissivity values of 14.1 ft2/day at
well MW-1(s), 27.8 ft2/day at MW-4(s) and 65.8 ft2/day at well MW-7(s). These values are very similar to those obtained
from the specific capacity tests and they suggest that the entire saturated thickness of the saprolite/PWR aquifer unit
did not contribute water during the pumping tests.
The specific capacity varied from 0.008 gallons per minute per foot (gpm/ft) at MW-8(i) and 0.017 gpm/ft at well MW-
3(i). This range of values indicates a low -yielding PWR zone at the two locations that were tested. These results also
correlate well to the low water production observed in bedrock during drilling and the absence of major, water -bearing
fractures confirmed by borehole geophysical surveys.
Hydraulic conductivity values derived from slug testing varied from 1.26 ft/day at MW-1(s) to 4.1 ft/day at MW-7(s).
Measured values at the site are reasonable for most Piedmont saprolitic soils derived from weathered crystalline
bedrock. Hydraulic conductivity also was calculated at MW-3(i) an MW-8(i) by using the maximum transmissivity
derived from specific capacity tests divided by the assumed aquifer thickness. Although the resultant hydraulic
conductivity values of 0.43 ft/day and 0.15 ft/day are feasible for a sandy silt saprolitic aquifer, these results may be an
order of magnitude too low due to the large aquifer thickness value used in the calculation.
3. Injectant Information
3.1 Soil Vapor Extraction System Operation
The soil vapor extraction (SVE) system, which is currently operated on site as an interim remedial measure, will
continue to run according to its operational schedule (two months operation followed by two -month shutdown). The
bottom of the SVE gravel pit is estimated to be approximately 15 feet above the water table. Mounded groundwater
associated with ERD injections is not anticipated to interfere with SVE operations.
3.2 Source Area ABC -Ole and Magnesium Oxide Injections
A dilute ABC -Ole, zero valent iron (ZVI), and Enviroblend® 93 (magnesium oxide) solution will be injected into a
treatment area (approximately 36,480 square feet) located in the source area, coincident with the upgradient portion
of the 1,000 pg/L PCE groundwater contour. The injection will be completed via DPT at 120 locations within the
source area. The proposed area DPT injection locations are shown in Figure 3, and proposed injection intervals are
summarized in Table 1. It is proposed that 103,850 gallons of a dilute ABC-Ole/ZVI/magnesium oxide solution be
injected into the source area. The total injection volume assumes a radius of influence of 10.5 feet and pore volume
replacement of 8 percent. The radius of influence is assumed based on the pilot study injection performed at the Site,
during which changes in field parameters were observed in monitoring wells approximately 10.5 feet away from DPT
injection points. Approximately 103,850 pounds of ABC -Ole (in situ dose of 9.5 grams per liter [g/L], 12% by weight),
103,850 pounds of ZVI (in situ dose of 9.5 g/L), and 10,385 pounds of magnesium oxide (in situ dose of 1 g/L) will be
injected. Injection make-up water will be derived from off -site sources.
ABC -Ole will be injected to create anaerobic conditions and provide an electron donor for dehalorespiring bacteria.
ABC -Ole contains a higher fraction of emulsified fatty acids than Anaerobic BioChem (ABC®), which can yield a
longer residence time for the carbon substrate. ZVI will be injected concurrently to rapidly reduce chlorinated solvents

upon contact through abiotic processes. Magnesium oxide will be used to buffer the groundwater pH which is
naturally low and also buffer groundwater from production of metabolic acids from biodegradation of the ABC -Ole.
Magnesium oxide provides an extended pH buffering time relative to sodium bicarbonate.
The injection amendments will be mixed aboveground in a batch process prior to subsurface delivery. The actual
methodology will depend on the capabilities of the selected injection subcontractor. Once mixed, this solution will be
injected into 120 direct -push locations (FS-1 through FS-120) at multiple depth intervals. The solution will be injected
using a pneumatic double diaphragm pump. Proposed injection quantities are summarized in Table 3. Materials
safety data sheets for the injection amendments are included as Appendix B.
3.3 Downgradient Barrier High Fructose Corn Syrup and Sodium Bicarbonate
Injections
A dilute high fructose corn syrup (HFCS) and sodium bicarbonate solution will be injected into two PWR barriers via
permanent injection wells. The injectant will be administered via five proposed permanent injection wells (IW-3
through IW-7) and one existing permanent injection well (IW-1) located directly south of the source area, and seven
proposed injection wells (IW-8 through IW-14) located approximately 270 feet south of the source area along
McCanless Street. Proposed injection well locations are shown in Figure 4, proposed well construction details are
summarized in Table 1, and proposed well construction diagrams are presented in Appendix A.
Injections into the permanent wells will target a 30-foot interval in the PWR aquifer at a general depth of 60-90 feet
bgs. A proposed injection volume of 900 gallons per well is estimated. The total injection volume assumes a radius of
influence of 10 feet and a pore volume replacement of 4 percent of total pore volume. The radius of influence is
assumed based on the pilot study injection performed at the Site, during which changes in field parameters were
observed in monitoring wells approximately 15 feet away from PWR injection wells. In order to ensure sufficient
treatment of downgradient groundwater, a more conservative radius of influence than that observed during the pilot
study was used for injection volume calculations for the downgradient PWR barriers. A total of approximately 8,300
pounds of HFCS (in situ dose of 8 g/L, 19% by weight) and 2,240 pounds of sodium bicarbonate (in situ dose of 2
g/L) will be injected into the onsite wells. A total of approximately 9,700 pounds of HFCS (in situ dose of 8 g/L, 19%
by weight) and 2,617 pounds of sodium bicarbonate (in situ dose of 2 g/L) will be injected into the off -site wells.
HFCS yielded favorable results when injected into PWR during the pilot study and will be injected in the PWR barriers
during the full-scale implementation to create anaerobic conditions and provide an electron donor for dehalorespiring
bacteria. Sodium bicarbonate will be injected to buffer the groundwater pH which is naturally low and to also buffer
groundwater from production of metabolic acids from biodegradation of the HFCS. Magnesium oxide has a relatively
low solubility and may clog well screens. Therefore, it cannot be used as a buffer in the PWR barrier injections.
One additional downgradient barrier will be completed via DPT in the shallow (saprolite) aquifer, approximately 270
feet downgradient of the source area (Figure 4). Injections will be completed in nine borings (FS-121 through FS-
129) and target a 20-foot interval at a general depth of 40-60 feet bgs. A proposed injection volume of 650 gallons per
DPT location is estimated. The total injection volume assumes a radius of influence of 7.5 feet and a pore volume
replacement of 6 percent of total pore volume. The radius of influence is assumed based on the pilot study injection
performed at the Site, during which changes in field parameters were observed in monitoring wells up to 10.5 feet
away from DPT injection locations. In order to ensure sufficient treatment of downgradient groundwater, a more
conservative radius of influence than that observed during the pilot study was used for injection volume calculations
for the downgradient saprolite barrier. Approximately 9,000 pounds of HFCS (in situ dose of 12 g/L, 19% by weight),
and 4,860 pounds of sodium bicarbonate and 585 pounds of magnesium oxide (buffer in situ dose of 4 g/L) will be
injected. Injection make-up water will be derived from off -site sources. Proposed injection intervals are summarized in
Table 1.
HFCS will be injected to create anaerobic conditions and provide an electron donor for dehalorespiring bacteria.
Sodium bicarbonate will be injected to buffer the groundwater pH which is naturally low and to also buffer
groundwater from production of metabolic acids from biodegradation of the HFCS. Additionally, magnesium oxide will
be incorporated into the injection solution to enhance pH buffering. Magnesium oxide has a relatively low solubility
and may clog the pump utilized for the HFCS injections. Therefore, only a small fraction of magnesium oxide will be
used in the saprolite barrier injections.

The injection amendments will be mixed aboveground in a batch process prior to subsurface delivery. The actual
methodology will depend on the capabilities of the selected injection subcontractor. Once mixed, this solution will be
injected into the locations at multiple depth intervals. The solution will be injected using a pneumatic double
diaphragm pump. Proposed injection quantities are summarized in Table 3.
3.4 Bioaugmentation
Bioaugmentation will be completed using the SDC-1® bioaugmentation culture at half of the source area DPT
injection locations. The culture will contain an enriched dechlorinating culture, including Dehalococcoides
ethenogenes bacteria (DHC), capable of complete dechlorination of PCE and its daughter products. Groundwater
data at the Site indicates that native dechlorinating cultures, especially DHC, were limited in some aquifer zones.
Therefore, bioaugmentation will be used to enhance the natural population of dechlorinating microbes in the ERD
treatment areas. Bioaugmentation injections will be performed at half of the source area injection locations via DPT.
Additional bioaugmentation may be completed at half of the DPT locations and permanent injection wells proposed in
downgradient areas. Each location will receive 2 liters of bioaugmentation culture per 10 vertical feet of treatment
interval.
4. Injection Procedure
The proposed DPT locations and permanent injection wells (described in Section 5) will be used to facilitate the
proposed injections. The proposed injection activities are estimated to take up to 70 days to complete, following well
installation and development. Additional injection crews may be utilized to decrease the length of the injection event.
Injection rates into the saprolite are expected to range from approximately 6 to 16 gpm, and injection rates into PWR
via permanent well and pneumatic pump are expected to range from 3 to 8 gpm. Injection pressures are expected to
range from 85 Pound -force per square inch (psi) to 200 psi at DPT injection locations, and are expected to be less
than 50 psi at injection wells. However, the injection rate, amount and pressure will vary depending on field
conditions. A summary of injection quantities is provided in Tables 1 and 3.
5. Well Construction Details
The full-scale ERD injection will include injections via DPT in the source area where PCE concentrations in the
saprolite groundwater plume exceed 10,000 pg/L, and in most of the onsite area with PCE concentrations in excess
of 1,000 pg/L, to reduce source area mass. The work will include injections via permanent wells immediately
downgradient of the source area, at an onsite barrier, and injections via DPT and permanent wells approximately 270
feet downgradient of the source area, at two off -site barriers. Proposed DPT injection locations and proposed
injection wells are shown on Figures 3-6, and proposed injection intervals are summarized in Table 1.
DPT injections in the source area will include advancing a total of 120 proposed temporary DPT injection points (FS-1
through FS-120) to total depths ranging from approximately 40 to 70 feet bgs. DPT injections at the off -site, saprolite
ERD barrier will include advancing a total of nine proposed temporary DPT injection points (FS-121 through FS-129)
pushed to total depths ranging from 50 to 60 feet bgs. The locations of the off -site DPT points are preliminary and
may be field adjusted based on data collected during a focused pre -injection DPT groundwater sampling event. DPT
refusal depths were assumed based on previous site drilling experience and may be modified according to field
conditions. After DPT injection locations have been completed, the borings will be abandoned using bentonite or
cement grout.
Twelve proposed permanent injection wells (IW-3 through IW-14) will be installed to complete the downgradient PWR
barriers. Five injection wells will be installed along the onsite PWR barrier and seven wells will be installed along the
off -site PWR barrier. The locations of the off -site wells are preliminary and may be field adjusted based on data
collected during a focused pre -injection DPT groundwater sampling event. The wells will be installed using a
combination of hollow stem auger (HSA) and air rotary techniques and will be spaced approximately 20 feet apart
and constructed of schedule 40 polyvinyl chloride (PVC) with 30-foot 0.010-inch screen. Additionally, one existing

injection well will be used to complete the onsite PWR barrier. Proposed well construction diagrams are presented in
Appendix A.
Two proposed shallow (saprolite) performance monitoring wells (PMW-5s and PMW-6s) and one proposed
intermediate (PWR) performance monitoring well (PMW-5i) will be installed at similar depths and screened intervals
as the injection points/wells in the source area and the downgradient ERD barriers. The locations of the off -site wells
are preliminary and may be field adjusted based on data collected during a focused pre -injection DPT groundwater
sampling event. Shallow monitoring wells will be installed using HSA techniques, and the intermediate monitoring well
will be installed using a combination of HSA and air rotary techniques. Performance monitoring wells will be
completed as 2-inch PVC with 10 feet of 0.010-inch screen. Proposed well construction diagrams are provided in
Appendix A.
Prior to performing any invasive work, utilities will be marked by a private utility locator and surrounding public utilities
will be marked by a public utility locating service via 811 ticket. Additionally, each sampling location will be pre -cleared
using a stainless -steel hand auger to a depth of at least 5 feet bgs. AECOM will complete and submit the necessary
documents to obtain right-of-way access for McCanless Street from the City of Winston Salem to install off -site
injection and monitoring wells. Solid and liquid investigative derived waste will be placed in drums, sampled, and
properly manifested and transported off -site for disposal.
6. Monitoring Plan
Prior to injection, existing and new injection and monitoring wells will be purged and sampled to establish baseline
conditions. The sampling parameters to be analyzed during the baseline sampling event and post -injection sampling
will follow the tentative schedule/parameter list presented in Table 4. Proposed injection well construction details are
summarized in Table 1 and existing well construction details are summarized in Table 5. Sampling frequency and
parameters may be modified during the injection performance monitoring, based on interpretation of the results.
7. Well Data Tabulation
See Table 5 for existing well construction details and Table X for proposed injection wells and DPT locations details.

KB-1® Dechlorinator is a microbial culture grown in an aqueous dilute mineral salt solution media
containing no hazardous ingredients.
The microbial composition of KB-1® Dechlorinator (as determined by phylogenetic analysis) is
listed in Table 1. Identification of organisms was obtained by matching 16S rRNA gene sequence
of organisms in KB-1® Dechlorinator to other known organisms. The characteristics of related
organisms can be used to identify potential or likely characteristics of organisms in KB-1®
Dechlorinator.

130 Research Lane, Suite 2 Guelph•Ontario • N1G 5G3 • Canada • Tel: [phone] • Fax: [phone]
Eye Contact: Flush eyes with water for at least 15 minutes, occasionally lift upper and lower
eyelids, if undue irritation or redness occurs seek medical attention.
Skin Contact: Remove contaminated clothing and wash skin thoroughly with water and
antibacterial soap. Seek medical attention if irritation develops or open wounds are present.
Ingestion: Do not induce vomiting, drink several cups of water, seek medical attention.
Inhalation: Remove to fresh air. If not breathing give artificial respiration. In case of labored
breathing give oxygen. Call a physician.
Section 5 - Fire Fighting Measures:
Non-flammable
Flash Point: not applicable
Upper flammable limit: not applicable
Lower flammable limit: not applicable
Section 6 — Accidental Release Procedures
Spilled KB-1® Dechlorinator should be soaked up with sorbant and saturated with a 10%
bleach solution (prepared by making a one in ten dilution of diluted standard bleach
[normally sold at a strength of 5.25% sodium hypochlorite] to disinfect affected surfaces.
Sorbant should be double bagged and disposed of as indicated in section 12. After
removal of sorbant, area should be washed with 10% bleach solution to disinfect. If liquid
from the culture vessel is present on the fittings, non -designated tubing or exterior of the
stainless steel pressure vessel liquid should be wiped off and the area washed with 10%
bleach solution.
Section 7 - Handling and Storage
KB-1® Dechlorinator is shipped in stainless steel pressure vessels and connected to
injection lines and inert gas is used to pressurize the vessel to displace the contents. KB-
Dechlorinator should be handled with care to avoid any spillage. Vessels are shipped
with 1 pound per square inch (psi) pressure; valves should not be opened until
connections to appropriate lines for subsurface injection are in place.
Storage Requirements: Avoid exposing stainless steel pressure vessels to undue
temperature extremes (i.e., temperatures less than 0°C or greater than 30°C may result
in harm to the microbial cultures and damage to the vessels). All valves should be in the
closed position when the vessel is not pressurized to prevent the escape of gases and to
maintain anaerobic conditions in the vessel. Avoid exposure of the culture to air as the
presence of oxygen will kill dechlorinating microorganisms.
Section 8 - Exposure Controls/Personal Protection
Personal protective equipment:
Skin: Protective gloves (latex, vinyl or nitrile) should be worn.
Eye Protection: Wear appropriate protective eyeglasses or goggles when opening
pressure vessels valves or when pressurizing vessels to inject contents into the
subsurface.
Respiratory: No respiratory protection is required.
Engineering Controls: Good general room ventilation is expected to be adequate.

Notes:
1. This figure is for conceptual purposes only. Proposed features are subject to change.
2. Injections are expected to be completed in a phased approach.
3. This site plan was constructed from surveys by Slate Surveying Co., PA ( October
2003) and Regional Land Surveyors, Inc. (Januar 2004, October 2004, February 2008,
October 2008, March 2013, and September 2013) . Locations of roads and property lines
were digitized from property deed maps and aerial photos obtained from the Forsyth
County, NC Tax Office and from the NC Department of Transportation. This survey does
not represent an accurate boundary survey and should not be used for such purposes.

The buildings at the site were demolished 2 to 3 years ago. All utilities were removed from the site so there are
no underground utilities in the injection or surrounding area. The SVE unit is currently in operation but,
according to Matt Allen, Project Manager for AECOM, the unit is likely to be shut down in a year since the
effectiveness of the system has significantly decreased. The in situ injection will be conducted by Regenesis.
