1 Introduction
1.1 Setting
Brownfields Application -Summary of Investigations
Forest City, North Carolina
Andale Inc .
The future data center property consists of approximately 160 acres and includes a former
manufacturing facility (the "northern portion" of the property) and approximately 90 acres of
adjacent wooded and vacant land (the "central and southern portions" of the property). The
northern portion of the property was developed with an approximately 370,000-square foot
building formerly used for manufacturing. Smaller structures on the site were primarily
associated with the onsite wastewater treatment plant 0/VWTP).
The central and southern portions of the site include wooded areas and land that had been
graded for development (currently covered with grass). An unnamed creek crosses the site
from the southwest to the northeast. The area surrounding the facility has primarily been used
for residential and agricultural purposes since at least the early 1960s.
1.2 Background
Historical information regarding the site indicate that prior to 1966, the site included wooded and
agricultural land, and one or more residences may have been located on the western or
southern portions of the site, along Old Caroleen Road and/or Low Bridge Road. In 1966, the
northern portion of the site was developed by Burlington Industries (Burlington) for use as a
textile manufacturing facility. Manufacturing operations consisted of washing and cleaning of
woven fabrics, fabric dyeing, washing and rinsing of dyed fabric, burling and mending, and
surface finishing operations (e.g., trimming, shearing, and steam pressing). Finished fabric was
shipped to other Burlington facilities for production of garments, upholstery and draperies.
Manufacturing operations were water-intensive, utilizing several million gallons per day
withdrawn from the Second Broad River adjacent to the site to the east. Process and sanitary
wastewater streams were treated at the facility's biological \NWTP and discharged via a
permitted outfall into the Second Broad River.
Burlington ceased operations at the site in March 1999, and the property was subsequently
acquired by Rutherford County in 2002. Beginning in 2003, Rutherford County leased the
facility on the northern portion of the site to Mako Marine (Mako) for use in fiberglass boat
manufacturing. The facility was connected to the municipal sewer system in 2003 and, as such,
Mako did not utilize the \NWTP. Operations conducted by Mako included open molding of
reinforced plastic composite boat parts, final assembly, testing, and shipment to Bass Pro
Shops for retail sale. Mako ceased operations at the site in 2009, and the property was vacated
until its acquisition and development by Andale Inc. in 2010 .

2.1 1990 Underground Storage Tank Closure Assessment
A 500-gallon underground storage tank (UST) formerly containing diesel fuel was excavated,
removed, and disposed offsite by Four Seasons Industrial Services, Inc. in January 1990.
Following removal of the tank, Aquaterra collected soil samples via hand auger to evaluate
whether petroleum hydrocarbons were present in the soil.
• Soil samples were collected at each end of the tank pit at depths of one and two feet
below the bottom of the pit and screened for volatile organic compounds (VOCs) using
an Organic Vapor Analyzer. Field screening results did not exceed 9.6 parts per million
(ppm).
• Two samples were collected from approximately 2 feet below the bottom of the tank pit
(4 to 4.5 feet below ground surface [ft bgs]) and submitted for laboratory analysis of total
petroleum hydrocarbons (TPH). The analytical results were non-detect for TPH (<2
milligrams per kilogram ([mg/kg]).
Based upon these activities, Aquaterra recommended that the site be considered for clean
closure.

limitations of ASTM Standard Practice E 1527-00. The findings and conclusions were as
follows:
• The historical aerial photography review did not reveal any readily observable evidence
of petroleum or hazardous substance spillage, or improper disposal activities on the
subject property or adjacent properties. Minor fuel staining was noted beneath one 500-
gallon diesel fuel AST, but the staining appeared to be minor and limited to the area
immediately beneath the AST. This AST is located within the dike for a 150,000-gallon
#6 fuel oil AST.
• The facility previously utilized a 500-gallon diesel fuel UST for a fire pump. According to
information obtained from Burlington, this UST was removed on January 8, 1990 with no
evidence of spills or leakage. Analytical results from samples submitted from the tank
closure also did not indicate evidence of a release. Burlington requested that the UST
incident be closed on February 6, 1990. Waters Edge recommended that an attempt be
made to obtain "No Further Action Recommended" correspondence from NCDENR.
• Evidence of leakage/spills was noted at each of the two hydraulically-operated fabric
presses within the facility.
• The regulatory database review did not reveal any environmental incidents, registration
or enforcement activity for the site or surrounding properties within the ASTM minimum
search distance. The property was listed on an AST registration database and is known
to be a SQG of hazardous waste.
• The SPCC Plan should be re-certified by a North Carolina-licensed Professional
Engineer.
• According to Burlington personnel, non-hazardous filter plant sludge (alum) was
historically land disposed of near the southeast corner of the property. The sludge in this
area were removed and disposed of in 1989-1990 according to NCDENR requirements.
No visual evidence of stressed vegetation, stained soils, or other contamination were
noted in this area during the site reconnaissance.
• Given the date of construction of the facility, ACMs are likely to be present at the site.
Additionally, there is a potential for lead-based paints at the facility.

2.3 January 2003 Phase 1 Environmental Site Assessment
In January 2003, Leonhardt Environmental, P.C. (Leonhardt) conducted a Phase I
Environmental Site Assessment on approximately 60 acres of the 122-acre tract of land
previously owned by Burlington. The major findings of this assessment were:

•
•
Brownfields Application -Summary of Investigations
Forest City, North Carolina
Andale Inc.
• No evidence was found which might indicate that the manufacturing activities within the
industrial building have impacted the surrounding soil or groundwater.
• No evidence was found that the wastewater treatment system has adversely impacted
the environment.
• No evidence was found that the sludge handling system and drying bed located
upgradient from the subject property has impacted soil or groundwater.
• Spillage was identified in proximity to a diesel tank located within the secondary
containment structure associated with the No. 6 oil storage tank. The extent of this
impact was not considered likely to be significant.
• Leakage onto the ground surface was observed from a paint storage shed. The extent
of this impact was not considered likely to be significant.
• A construction debris landfill was found near the eastern boundary of the subject site.
The amount of material placed in the landfill was extensive, however, no evidence was
found that an impact to the environment has occurred as a result of the landfill.
• No evidence was found of any impacts onto the subject site from nearby off-site sources .
The report concluded that limited environmental impacts to the subject site have occurred and
that due to the age of the facility and the extensive nature of the wastewater treatment system,
that it is possible, if not likely that additional impacts have occurred in the area surrounding the
treatment system. Additionally, the report recommended that the two identified areas of
contamination be remediated and that soil and groundwater sampling be conducted in four
general areas to establish whether or not contamination has occurred in those areas.

2.4 2003 Limited Site Investigation
From January 20, 2003, through January 29, 2003, Mid-Atlantic Associates, Inc. (Mid-Atlantic)
conducted soil, surface water, and groundwater assessments and sampling activities at the
request of Tracker Marine (i.e., Mako). Areas investigated included near the ASTs located to
the west and southeast of the main building, the former paint storage building south of the
eastern portion of the main building, an area containing construction debris along the creek in
the central portion of the site, and the \NNTP. Samples were analyzed for volatile organic
compounds (VOCs), semi-volatile organic compounds (SVOCs), TPH, and Resource
Conservation and Recovery Act (RCRA) metals. A summary of the findings is presented below:
• Three VOCs (bromomethane, chloromethane, and p-isopropyltoluene) and gasoline
range organics (TPH-GRO) were detected in soil samples obtained during the
installation of a groundwater monitoring well (MW-7) on the eastern portion of the site, in
07-25566 5 E:NVIRON

the WWTP area. Concentrations of these voes were less than the NCDENR's Soil
Cleanup Levels (SCLs).
• Concentrations of diesel range organics (TPH-DRO) greater than the NCDENR SCL of
40 mg/kg were detected in soil samples obtained from near transformers on the west
side of the WWTP building and near the debris pile near the centrally located creek.
• Chromium concentrations in soil samples from several borings exceeded the NCDENR
SCL of 27 mg/kg. However, the detected concentrations were similar to the background
soil sample collected during the investigation.
• Lead and selenium were detected in surface water samples collected from the Second
Broad River adjacent to the site at concentrations that exceeded the North Carolina
Surface Water Quality Standards of 25 µg/I and 5 µg/I, respectively.
• A PCE concentration of 2.6 micrograms per liter (µg/I) was detected in MW-4 at the
northeastern portion of the site and exceeds the North Carolina Groundwater Quality
Standard (NCGWQS) of O. 7 µg/I. Additionally, 1,4-dichlorobenzene and chlorobenzene
in MW-6 near the former paint storage building and 1, 1-dichloroethene in MW-7 were
detected at concentrations that did not exceed the NCGWQSs.
• Arsenic, barium, chromium, and lead concentrations in MW-1 (located to the west of the
industrial building) and MW-5 (located on the northeastern portion of the site, in the
WWTP area) exceeded the NCGWQSs. However, dissolved concentrations of these
metals were less than the respective NCGWQSs and indicate that the presence of
suspended colloidal material in the groundwater likely contributed to "false positives."
Mid-Atlantic recommended remediation of TPH-impacted soils near the transformers on the
west side of the WWTP building and near the debris piles in the central portion of the site as
well as re-sampling of groundwater in the WWTP area to confirm the presence of PCE or the
installation of additional monitoring wells to delineate the extent of PCE impact.

Industries Site, Old Caroleen Road, Forest City, North Carolina. February 13.
2.5 2003 Soil Remediation
Based on the findings of the 2003 investigation and subsequent field observations Mid-Atlantic
conducted soil remediation activities at the site in April 2003, including the exaction, removal,
and disposal of TPH-impacted soil. The remediation areas consisted of an area near the former
paint storage building, near transformers on the west side of the WWTP building, near debris
located in the central portion of the site, and near a 250-gallon diesel fuel AST formerly located
within the containment area of the No. 6 fuel oil tank. Remediation efforts included:
• The removal of approximately 35 cubic yards of petroleum-impacted soil from near the
former paint storage building;
07-25566 6 E:NVll\ON
•
•
•
Brownfields Application -Summary of Investigations
Forest City, North Carolina

• The removal of approximately 5 cubic yards of petroleum-impacted soil from the west
side of the WNTP building;
• The removal of approximately 0.5 cubic yards of petroleum-impacted soil and
construction debris from the central portion of the site;
• The removal of approximately 16 cubic yards of petroleum-impacted soil near the former
250-gallon AST west of the main building; and
Based on visual observations and confirmation samples that were collected following excavation
activities, the report indicated that petroleum-impacted soil was "effectively remediated" in the
areas of concern, with the exception of an area on the west side of the former diesel fuel AST
that was in close proximity to a containment wall and footer. With respect to that area, Mid-
Atlantic recommended additional excavation and removal activities during the demolition of the
site. Additionally, chromium concentrations exceeded the SCLs but were consistent with
previously identified background concentrations

2.6 2004 Jurisdictional Wetlands and Waters of the U.S. Delineation Report
S&ME, lnc.'s (S&ME's) evaluation of the Jurisdictional Wetlands and Waters of the U.S.
Delineation, conducted in June -July, 2004, consisted of the following tasks:
• Evaluation of the property for conditions consistent with the definition for jurisdictional
wetlands as set forth in the 1987 USA COE "Wetland Delineation Manual", identification
of the limits of the onsite wetlands and onsite U.S. waters, and demarcation of
upland/wetland boundaries.
• Development of an Approximate Wetlands and Waters of the U.S. Map that detailed the
extent and location of the delineated wetlands and waters of the U.S.
Based on the evaluation, S&ME recommended that the jurisdictional limits defined by the
evaluation should be verified by the USACOE, and the delineated boundaries surveyed and
platted by a registered land surveyor.

2. 7 2004 Phase I Environmental Site Assessment
In June 2004, S&ME performed a Phase I Environmental Site Assessment for an approximately
70-acre tract of land at the northern portion of the property. A summary of the significant
findings is presented below:
A leaking underground storage tank (LUST) incident was associated with the removal of the
500-gallon diesel UST 1990. NCDENR issued an NFA fetter for the incident on February 15,
1990. A second incident was reported due to a petroleum release that impacted soil and

groundwater in May, 1998r. NCDENR issued an NFA letter for the incident on November 25,
1998.
A 20,000 gallon fuel oil UST was removed from the site in 1999.
Large amounts of construction debris, primarily consisting of concrete block, were observed
along the northern property boundary at the edge of the Tracker Marine facility. Several smaller
debris piles consisting of old cans and assorted household waste were observed in the wooded
portion of the property, west of the power line easement. The site reconnaissance revealed no
signs of spills, stressed vegetation, buried waste, USTs or ASTs, subsidence, transformers, or
unusual soil discoloration.

2.8 April 2005 Environmental Site Assessment
Odom Hollifield & Associates Engineering, Inc. contracted MACTEC Engineering and
Consulting (MACTEC) to conduct groundwater sampling at the site to determine what impact, if
any, the former lagoon (identified as a REC in the 2004 S&ME Phase I Report) had on the
proposed Rutherford 74 Corporate Center Site.
MACTEC installed a temporary groundwater monitoring well downgradient of the former
wastewater lagoon. The well was advanced by direct push technology (DPT), and the screen
interval was set at 7-12 ft bgs. The well was developed, and a groundwater sample was
collected and analyzed for metals. The analytical results did not not exceed the North Caolina
groundwater standards. Additionally, as a part of the lease agreement with Mako, the lagoon
was closed in accordance with NCDENR standards.

2.9 April 2009 Phase I Environmental Site Assessment
Leonhardt conducted a Phase I Environmental Site Assessment at the property in April 2009.
The following RECs or concerns were identified:
• No records were identified that indicate that the WWTP lagoon closed in 2005 was
closed in accordance with State of North Carolina guidelines. Accordingly, it could not be
ascertained if any residual soil or groundwater contamination was present. At the time
of the report, sampling was being undertaken to complete the closure activities and
satisfy the requirements of the State of North Carolina.
• No other significant environmental conditions or concerns were found either inside the
main manufacturing building or on the balance of the site outside of the building.
• No likely environmental impacts onto the subject site were identified from offsite sources
or sites.

The following action was recommended:
• All appropriate steps should be taken to determine and document that soil and
groundwater contamination does not remain as a result of the previous usage of the
waste water treatment lagoon.
• No additional assessment of soil or groundwater was recommended.

2.10 May 2009 Limited Subsurface Investigation Report
S&ME installed eight DPT borings for the purpose of collecting analytical data to finalize the
closure of the former process water filter treatment lagoon, screening soils beneath the former
waste filtering unit and former sludge drying bed, and determining background concentrations of
naturally occurring metals.
• Barium concentrations exceeded the background soil concentration in 8-1@ 14 ft bgs
(from the bottom of the water filter treatment lagoon);
• Arsenic concentrations detected in the background sample (250 mg/kg) was consistent
with what would be expected in typical, undisturbed native soils for this geographic
region. No visual indications of disturbance were noted in this sample;
• voes were detected in B-1@14 ft bgs and B-2@4-5 ft bgs (from the fill material within
the lagoon);
• TPH-DRO was detected in 8-1@14 ft bgs and 8-5@23 ft bgs (residual soils beneath the
waste filtering lagoon).

2.11 August 2009 Monitoring Well Installation and Sampling Report
At the request of NCDENR, S&ME installed one Type II groundwater monitoring well (TW-1)
downgradient of the former process water filter treatment lagoon. for the purpose of determining
whether the operation of portions of the former WWTP area may have impacted groundwater
quality in the surficial aquifer. A summary of the conclusions is as follows:
• The operation of the former WWTP has not adversely impacted groundwater quality with
respect to concentrations of RCRA metals and total petroleum hydrocarbons.
• Analytical results from the initial and confirmatory groundwater samples collected from
TW-1 indicated the presence of PCE at concentrations of 39 and 46 µg/I, respectively.
• Groundwater quality conditions detected at TW-1 are not expected to pose a risk to
surface water quality

PCE was not detected in soil samples collected by S&ME in May 2009 (2009 Limited
Subsurface Investigation Report) from within the footprint of the former waste treatment
units, including a soil sample obtained from the former sludge drying bed, which lies
immediately upgradient of well TW-1. As such, S&ME concluded that the detection of
PCE in TW-1 may represent an isolated occurrence of this constituent.
Based on the conclusions, Rutherford County requested that NCDENR finalize closure of the
process water filter treatment lagoon, the three concrete clarifiers, the sludge drying bed, and
the waste filtering bed.
S&ME 2009. Monitoring Well Installation and Sampling Report TW-1. August 31.
2.12 December 2009 Limited Groundwater Assessment Report
The August 2009 Limited Groundwater Assessment Report was conducted in response to a
Notice of Violation (NOV) regarding the previous exceedances of PCE NCGQS that was issued
by the Aquifer Protection Section of the NCDENR to Rutherford County on September 10, 2009.
To satisfy the requirements of the NOV, Mid-Atlantic installed and sampled twelve additional
monitoring wells on the property. The analytical results indicate:
• PCE was detected in four of the 12 newly installed wells (MW-8, MW-10, MW-11, and
MW-12) at concentrations exceeding the NCGQS .
• PCE was detected in TW-1 (installed in August 2009) at a concentration greater than the
NCGQS.
The report concludes that groundwater in the vicinity of the former sludge drying beds and
former waste filtering beds had been adversely impacted by PCE in excess of the NCGQS of
0. 7 ug/L. The report ctoes not identify a source of the PCE but states that it probably originated
in the vicinity of the former sludge drying bed located approximately 100 feet hydraulically
upgradient of the most upgradient impacted monitoring well, MW-11. Additionally, the report
indicates that the groundwater contaminant plume is migrating toward the north/northeast,
toward the Second Broad River; the downgradient extent of impacted groundwater was not
determined due to the steepness of the land topography.

2.13 May 2010 Phase I Environmental Site Assessment
Leonhardt conducted a Phase I Environmental Site Assessment of an approximately 5-acre
parcel along the eastern portion of the property. No RE Cs or other environmental concerns
were found during the assessment, with the exception of the items identified below:
• Groundwater was found to be impacted by PCE. The report indicates that the source of
the impact had not been identified; however, the nature of the contamination leads to the
conclusion that the source was likely the illegal dumping of PCE which appears to have
occurred at some point during the construction of the industrial park.

• No environmental conditions identified in any previous environmental assessment, and
located on the current confines of the larger property (i.e., the future data center
property) continue to be a concern.
• The former sludge drying beds were not formally eliminated as a potential source of the
groundwater contamination found on the subject site. The State of North Carolina
requested that additional data be collected to formalize the closure.
The report recommends the following:
• The sludge drying bed should be further assessed to eliminate the beds as a potential
source of the groundwater contamination.
• The groundwater impacts should be further assessed to determine their vertical and
horizontal extent.
• Additional sampling of soil and groundwater will be required at the subject site prior to
any closure by the regulatory agency.

2.14 July 2010 Assessment of Asbestos Containing Building Materials (ACBM)
An asbestos survey of the former Burlington Industries building located in Forest City, North
Carolina, was conducted on July 1, 2010. The results of the survey indicated that the facility
has a significant amount of ACBM present. The ACBM was found to be in generally good
condition with some localized damage. The four major types of ACBM found during the survey
are:
• Floor tile and mastic
• Hot water and steam condensate pipe insulation
• Stack insulation
• Transite building panels

2.15 July 2010 Annual Monitoring (Year 4)
The fourth annual monitoring summary of transplanted dwarf-flowered heartleaf (Hexastylis
naniflora) at the property was conducted in July 2010. S&ME personnel monitored plants at the
transplant location and at 19 areas where dwarf-flowered heartleaf plants previously existed
onsite and were placed in a deed-restricted buffer as part of mitigation for a previously
completed road crossing. The purpose of the monitoring was to determine the survivorship of

the transplants, the reproductive potential of the transplants, the general health of the
transplants, and the adequacy of the 100-foot buffers in relation to mitigating secondary impacts
from adjacent construction and/or development.
The report concluded that:
• Transplantation of specimens H. naniflora resulted in a stable and acceptable
survivorship of the transplants;
• Off-site stormwater discharges are resulting in indirect impacts on some subpopulations
within the study area. However these adverse effects are not related to, and are not a
consequence of, the Rutherford 7 4 Corporate Center development; and
• No further action is required by the USFWS to fulfill Section 7 obligations.

2.16 September 2010 Phase I Environmental Site Assessment
The following RECs were identified in the September 2010 Phase I Environmental Site
Assessment conducted by ENVIRON International Corporation (ENVIRON):
• Known Perchloroethylene (PCE) Groundwater Contamination. During a 2003 site
investigation, a concentration of 2.6 micrograms per liter (µg/I) of PCE was detected in
monitoring well MW-4 at the northeastern portion of the property, within the WWTP area.
This concentration exceeds the North Carolina Groundwater Quality Standard
(NCGWQS) of 0. 7 µg/I. In August 2009, concentrations of PCE were detected in in
monitoring well TW-1, located. downgradient of the former sludge drying bed, at
concentrations ranging from 39 µg/I to 46 µg/I.
• The North Carolina Department of Environment and Natural Resources (NCDENR)
issued a Notice of Violation (NOV) on September 10, 2009 for violation of the
NCGWQSs. In December 2009, groundwater from four monitoring wells in the area of
the former sludge drying bed were found to contain concentrations of PCE ranging from
5 µg/I to 1 O µg/I. According to investigation reports, the process water filter treatment
lagoon, clarifiers, and waste filtering beds were ruled out as potential sources of the
PCE. In February 2010, the NCDENR required Rutherford County to install an additional
well in the center of the former sludge drying bed, and in August 2010, Mid-Atlantic
indicated to the NCDENR that PCE was not detected above the laboratory detection limit
in groundwater from that well.
• According to a letter from the NCDENR to Rutherford County dated August 23, 2010,
Rutherford County has met the requirements in the NOV and guidance document for
closure of the treatment ponds and lagoon. Additionally, the NCDENR is requiring no
further action in regards to closure of the process water filter treatment lagoon, the three
clarifiers, the sludge drying bed, and the water filtering lagoons. However, the letter

indicates that the matter is being transferred to the Division of Waste Management's
Brownfields program and/or the Inactive Hazardous Sites Branch for further review, and
additional site assessment and/or cleanup activities may be required in the future.
• According to the site contacts, an approximately 5-acre portion on the eastern portion of
the site that encompasses the wells in which PCE was recently detected in the area of
the former sludge drying bed will be retained by Rutherford County during the sale of the
site, and that Rutherford County will be responsible for handling any additional actions
associated with that portion of land. Given the absence of an identified source of PCE,
other portions of the site may be scrutinized in the future to identify the source of the
PCE.
• Elevated Metals Concentrations in Soils. During the 2003 investigation activities at the
site, chromium concentrations in soil samples from several borings exceeded the
NCDENR SCL of 27 mg/kg. During the 2003 investigation, concentrations of lead and
selenium were detected in surface water samples collected from the Second Broad
River adjacent to the site at levels greater than the NCSWQS of 25 µg/I and 5 µg/I,
respectively .. In May 2009, arsenic and chromium were detected at concentrations of
250 mg/kg and 50 mg/kg, respectively, in a "background" soil obtained from an area
southwest of the main building; the historical reports indicate that these concentrations
are indicative of background levels in the area. The NCDENR has not required
Rutherford County to remediate these soils and the detections of elevated metals in
onsite soils has not apparently affected the closure proceedings for key features of the
WWTP. It is noted that a portion of the soils exhibiting elevated metal concentrations are
located within the approximately 5-acre portion on the eastern portion of the site that will
be retained by Rutherford County during the sale of the site.
• Remaining Petroleum-Impacted Soil. Remediation efforts conducted at the site in 2003
included the removal of approximately 16 cubic yards of petroleum-impacted soil near a
former 250-gallon AST located to the west of the main building. The 2003 remediation
report for the remedial activities indicated that petroleum-impacted soil on the west side
of the former diesel fuel AST that was in close proximity to a containment wall and footer
was left in place. With respect to that area, Mid-Atlantic recommended additional
excavation and removal activities during the demolition of the site.
Additionally, ENVIRON identified the following other findings:.
• Potential impacts from historical operations and materials handling;.
• Available information indicates that additional investigation and/or remedial actions are
not warranted in the UST areas;
• Based on test data, it appears that soil impacted by petroleum hydrocarbons in the areas
of concern (with the exception of the former diesel fuel AST area) was removed from the
site such that there is a low likelihood for future regulatory scrutiny of these areas, and a

low likelihood that additional investigation and/or remedial actions is required in these
areas with respect to petroleum hydrocarbon impacts.

Developed and vacant/Wooded Land, U.S. Highway 7 4 and Old Caroleen Road, Forest City,
North Carolina.
2.17 October 2010 Focused Phase II Site Assessment Report
To assess the potential magnitude of the environmental conditions defined in the Phase I,
ENVIRON conducted a focused Phase II site assessment in September 2010. The purposes of
the focused Phase II included confirmation of historical results and to obtain information about
potential contamination in proximity to the Mako building and deeper aquifer. To those ends, soil
samples were taken from and wells were located near areas of potential concern (such as the
Mako building and the previously-observed PCE groundwater contamination). The focused
Phase 11 included the following activities:
• Installation of six Type II groundwater monitoring wells;
• Installation of four Type Ill groundwater monitoring wells in bedrock;
• Collection of soil samples during boring advancement and field analysis with a photo-
ionization detector (PIO);
• Based on PIO readings and field observations, submission of eight soil samples for
laboratory analysis of VOCs and RCRA Metals;
• Collection of groundwater samples from the 1 O newly-installed monitoring wells and 17
previously existing wells and submission of these samples for laboratory analysis of
VOCs and RCRA Metals.
The results of the sampling indicate that:
• Impacts to the soil at the site, if any, are relatively minimal in both nature (in terms of the
constituents detected) and extent (in terms of the area that might be impacted.
• Impacts to the groundwater are very limited, primarily associated with PCE in the
central-eastern portion of the property. The concentrations in all but one of the six wells
in which PCE was detected in 201 O were less than 1 O µ/L.
o PCE in TW-1 was detected at a concentration of 34.3 µ/L (a reduction from 46.8
µ/L in November 2009).

3 Recent Environmental Investigations
In November 2010, Andale Inc. commenced development of the property for use as a future
data center. Since that time, ENVIRON has conducted two investigations to evaluate the
potential for contamination including, but not limited to, underneath the former Mako Marine
building and around two onsite lagoons that were historically a part of the WWTP at the former
Burlington Industries and Mako Marine building. A summary of the sampling events is
presented in the sections below.
3.1 Former Wastewater Treatment Plant Investigation
In April 2011, ENVIRON conducted an environmental sampling investigation within and around
four onsite lagoons that were historically a part of the WWTP at the property, to the east of the
former Mako building. Based on the proposed site development activities, which include the
development of a storm water retention pond in the area of the WWTP and daylighting the
existing stream, DPT drilling methods were utilized to advance 47 soil borings in the proposed
development areas (Figure 2). The soil borings were advanced for the purpose of obtaining
depth to water (DTW) measurements and to screen the soil for indication of historical impacts.
In addition, ENVIRON collected surface water and sediment samples from the four lagoons to
evaluate options for disposing of those materials prior to construction.
3.1.1 Soil Borings
Soil borings were advanced using DPT to the water table, and the saturated zone was identified
to determine the total DTW. In addition, approximately one-third of the borings were left open
for 1-2 days to allow for a measurement of the static water level using an electronic water level
meter. Soil was screened for voes using a PID and ReRA metals using an x-ray fluorescence
(XRF) spectrometer at 1-foot and 3-foot bgs and then at successive 5 ft intervals (i.e., 8 ft bgs,
13 ft bgs, etc.) until encountering the saturated zone. Any staining or odors that are observed
were visually described and recorded in a field log book. A total of 12 soil samples were at
random and based on field observations and were submitted for laboratory analysis for voes
and ReRA Metals. Finally, a global positional system (GPS) was used to determine the
horizontal position for each boring location.
Upon completion of the screening and gauging activities, the boreholes were backfilled with the
native soil and bentonite chips (which were hydrated to seal the boring) or bentonite grout
mixture where necessary. To the extent feasible, the ground surface at each boring location
was restored to match the original condition and surrounding grade
3.1.2 Surface Water and Sediment Sampling
After gauging the depth of the lagoons, ENVIRON field personnel collected two surface water
samples from each of the concrete-lined lagoons (the E-W lagoons), one surface water sample
from each of the vegetated lagoons (the N-S lagoons), one surface water sample from a
historical clarifier to the east of the E-W lagoons, and two surface water samples from a holding
pond to the north of the former Mako building using a peristaltic pump attached to dedicated and
disposable tubing. Additionally, two sediment samples were collected from each of the E-W and

the N-S lagoons. The sediment samples were collected from approximately 1/3 of the way "in"
along the long axis of the E-W lagoons, at the approximate midpoint along the short axis, and
from approximately 5 feet off the banks of the N-S lagoons. In addition, an attempt was made to
collect the surface water samples from the middle depth of the standing water level in each
lagoon.
The surface water and sediment samples were shipped via overnight carrier under standard
chain of custody protocol to Test America's Nashville, Tennessee laboratory for analysis of
voes by USEPA SW-846 Method 8260C, semi-volatile organic compounds (SVOCs) by
USEPA SW-846 Method 82700, and RCRA metals by USEPA SW-846 Methods 6010B (and
7470A for mercury).
3.1.3 Results
A summary of surface water results is presented in Table 4, and a summary of the soil and
sediment results is presented in Table 6. In general,
• Barium, chromium, and lead were detected in surface water at concentrations that were
significantly less than the North Carolina Water Quality Standard for Freshwater Aquatic
Life;
• Arsenic concentrations exceeded the North Carolina Preliminary Health-Based Soil
Remediation Goals (SRGs) in all but one of the soil and sediment samples. However,
the concentrations are consistent with what previous consultants and NCDENR have
indicated to be naturally-occurring conditions in the area; and
• Nine voes were detected in the soil and sediment samples. Of these, 1,4-
Dichlorobenzene (1,4-DCB) in the East Lagoon was the only voe with concentrations
that exceeded its SRG. At the request of NC DENR, ENVIRON collected three
additional sediment samples from the East Lagoon in May 2011. 1,4-DCB
concentrations in one of these samples slightly exceeded the SRG. However, it should
be noted that these concentrations are compared to soil criteria even though they were
detected in sediment samples with a heavy moisture content.
3.2 Limited Environmental Site Investigation -Former Mako Marine Building
In May 2011, ENVIRON conducted a limited environmental site investigation (ESI) that focused
on soil and subsurface soil vapor underneath the former Mako Marine building to identify
potential impacts that may be associated with historical concentrations of VOCs in groundwater.
Subslab (i.e., beneath concrete flooring) soil samples at 18 locations within the former Mako
building. Additionally, ENVIRON collected 12 subslab vapor samples in order to determine the
current air quality at the site. The sampling locations are depicted on Figure 3
3.2.1 Soil Sampling
Following the demolition of the roof and walls of the former Mako Marine building, ENVIRON will

historical site activities. As depicted on Figure 3, the sampling locations provided
representative coverage of areas with the concrete slab on-grade (SB-1 through SB-14) as well
as areas in the basement (SB-15 through SB-18). Subslab soil was exposed by breaking the
concrete slab with a jackhammer, DPT rig with attached star bit, or similar equipment. Soil
samples were collected by advancing DPT dual-core tooling with an acetate sleeve liner.
Boreholes were advanced to a minimum depth of 5 ft bgs, and the soil was screened upon
exposure for voes using a PIO and ReRA metals using an XRF spectrometer in 1 foot
intervals. Soil samples were visually inspected for color, grain size, density, moisture content,
staining, and odor and analyzed for voes and ReRA metals from the 0-1 ft and 4-5 ft bgs
intervals. In areas where pits were present (presumably used for historical dyeing operations),
boreholes were advanced in proximity to and downgradient from the pits. Soil from these
borings was screened as described above and analyzed for voes and ReRA metals from the
4-5 ft bgs and 7-8 ft bgs interval to ensure that samples were collected from below the pit invert.
In areas that were not accessible by drilling rigs (i.e., basement locations), boreholes were
advanced by hand auger to a depth of 4 ft bgs, and the soil column was screened and sampled
in the same manner as described above.
A handheld GPS was used to determine the horizontal location of each soil sample. Upon
completion, boreholes were backfilled with soil from their respective boring and topped off with
bentonite chips. Drilling and sampling equipment was decontaminated prior to the initial boring
and between each subsequent boring location .
3.2.2 Subslab Soil Vapor Sampling
Subslab vapor samples were collected from beneath the slab in 12 locations throughout the
northern portion of the former Mako building (Figure 3). To the extent possible, the samples
were collected from locations within the footprint of the future site building. The subslab
samples were collected from temporary sampling probes installed through the building slab,
using the following procedures:
• A 3/8 inch hole was drilled through the concrete slab using an electric hand-held
hammer-drill. The drill bit was advanced past the bottom of the slab into the subslab
material to create an open cavity. A section of 0.25-inch outside diameter (OD) by 0.18-
inch inside diameter (ID) stainless steel tubing was inserted into the concrete slab and a
non-volatile-emitting surface sealing material (i.e., modeling clay) was used to seal the
annular space. The bottom of the probe was installed to "float" in the concrete slab.
• Each vapor probe was connected to dedicated Teflon tubing. The vapor probe and
sample tubing was purged, by drawing a minimum of three volumes through the probe
and connecting tubing at a flow rate of approximately 100 milliliters per minute.
A helium tracer test was performed as part of the purging process to verify the integrity
of the probe seal using the same procedures described for the exterior soil vapor wells,
above .

• Samples were collected from the vapor probe locations into evacuated laboratory-
cleaned 1-Liter stainless steel Summa® canisters at a flow rate of 100 mUmin. The
canisters were equipped with a regulator pre-set by the laboratory to correspond to a 10-
minute sampling time and are stopped with the regulators showing negative pressure
(approximately 5" Hg) to ensure the presence of a residual vacuum.
Upon completion of the sampling, the temporary subslab probes were removed and the
concrete slab was sealed using quick-drying hydraulic cement.
3.2.3 Laboratory Analysis
All samples were collected and shipped via overnight carrier to Test America's Nashville
laboratory under standard chain of custody protocol. The soil and groundwater samples were
analyzed for voes by USEPA SW-846 Method 8260C. Additionally, the soil samples were
analyzed for RCRA metals by USEPA SW-846 Methods 60108 (and 7470A for mercury). The
Summa canisters were shipped to Test America's Knoxville, Tennessee laboratory for analysis
of VOCs by USEPA Method T0-15.
3.2.4 Results '?{.,Vb $ {'4,
A summary of soil and ~vapor results are presented in Tables 6 and 7 respectively. In
general,
• Several metals and VOCs were detected; however, with the exception of arsenic, no
constituent concentrations exceeded the respective SRGs. Arsenic concentrations were
consistent with what is expected to be naturally-occurring conditions in the area .
..,...~~~
• PCE and TCE were detected in three 5¢) vapor samples (SV-03, SV-08, SV-09) at
concentrations that exceeded the Acceptable Soil Gas Concentrations identified in the
IHSB Industrial/Commercial Vapor Intrusion Screening Criteria.
07-25566
o Per the North Carolina Supplemental Guidance for the Evaluation of Structural
Vapor Intrusion Potential for Site Assessments and Remedial Actions Under the
Inactive Hazardous Sites Branch (dated October6, 2010), the maximum
detected result for each of these constituents were modeled to estimate potential
vapor intrusion risks using conservative parameters based on the proposed
building plans.
o The concentrations identified correspond to a "collective" cancer risk of 2.2E-7
and a hazard index of 0.00014. These values are significantly less than the
standard points of departure. Based on these results, no additional sampling is
required, and the potential for vapor intrusion within the proposed commercial
structure is considered to be insignificant.
