1.0 INTRODUCTION
On behalf of the Prospective Developer (PD), 1105 Main Street, LLC, Geosyntec Consultants of
NC, P.C. (Geosyntec) is pleased to submit this Underground Storage Tank (UST) Closure Report
for the West Main Street Assemblage located at 1105 West Main Street in Durham, Durham
County, North Carolina (herein referred to as the "subject site" or "site"). The subject site is located
on the south side of West Main Street between West Peabody Street and West Morgan Street, on
the parcels formerly addressed as 1107 and 1105 West Main Street and 1026 and 1024 West
Peabody Street. The four parcels were combined into one +/- 0.79-acre parcel identified as
Durham County Parcel Identification Number (PIN): 0821-07-69-0363 and addressed as 1105
West Main Street, as part of the June 8, 2018 acquisition and planned redevelopment by the PD.
Construction of a six -floor mixed -use condominium high rise known as "The Bartlett" is currently
underway, with building occupancy planned for the fall of 2019. Ground floor space will be
designated for office, amenity, and commercial uses. Condominiums and common space will be
located on remaining upper floors (two through six). The site location is depicted on the
topographic map presented as Drawing 1. Pre -redevelopment site features and planned
redevelopment are depicted on Drawing 2.
Section 2.0 of this report provides an environmental history of the site. UST Closure activities
performed at the beginning of redevelopment soil disturbance activities in August 2018, and
subsequent groundwater sampling in the excavation area performed in April 2019, are summarized
in Sections 3.0 and 4.0. Section 5.0 provides a brief receptor survey discussion. The complete
Groundwater Assessment Report (McAdams) dated April 18, 2019, in addition to a Receptor
Survey (McAdams) dated August 28, 2019, were previously submitted under separate cover to the
North Carolina Brownfields Program (NCBP). Findings, conclusions and recommendations are
discussed in Section 6.0.
2.0 SITE ENVIRONMENTAL HISTORY
According to a Phase I Environmental Site Assessment (ESA) (McAdams, 2017a), the subject site
was historically used for residential and commercial purposes (Drawing 2). During a Limited
Phase II ESA (McAdams, 2017b), heating oil impacts were identified in soil around an
underground storage tank (UST) located in the rear of the former house on the parcel addressed as
1105 West Main Street (Drawing 2). Based on Phase I and Phase II ESA results, the site was also
suspected to have been potentially impacted from the following:
• Urban in -fill, naturally occurring and/or anthropological on -site sources;

• Regional off -site groundwater contamination from leaking underground sanitary sewer and
municipal water lines; and,
• Regional off -site groundwater contamination from chlorinated solvent/petroleum releases.
The subject site was found eligible for the North Carolina Department of Environmental Quality
(NCDEQ) NCBP on October 2, 2017 and is identified as NCBP Project Number 21038-17-032.
An Environmental Management Plan (EMP) was developed for the subject site following NCBP
eligibility. The objective of the EMP was to establish procedures for the handling, reusing,
transporting, and disposing of known and potentially contaminated soil and water generated during
redevelopment activities to protect the safety of construction workers, future site occupants, and
the surrounding area. The EMP was approved by the NCBP on March 22, 2018. UST Closure was
performed in general accordance with the approved EMP and NCDEQ UST Section, Guidelines
for Site Checks, Tank Closure, and Initial Response and Abatement for UST Releases (January 9,
2018).
3.0 UST CLOSURE ACTIVITIES
On August 20, 2018, McAdams observed contractor James Bobby Currin & Sons, Inc. (JB Currin)
of Fuquay Varina, North Carolina expose the top of the estimated 500-gallon heating oil UST
using excavation equipment. Upon confirmation of the presence of a UST, the area was covered
with plastic, and the City of Durham Fire Marshal was notified by General Contractor, Resolute
Building Company (Resolute) out of Chapel Hill, North Carolina, of the intent to remove the UST.
The UST area is depicted on Drawing 3.
On August 22, 2018, JB Currin excavated around the sides of the tank to evaluate the condition
and (potential) presence of residual sludge/liquids in the UST. Based on field observations, the
UST appeared to be corroded with little measurable heating oil sludge/liquid remaining in the
UST.
The inside of the tank was pressure washed by Zebra Environmental & Industrial Services (Zebra)
out of High Point, North Carolina. Wash water/fluid (sludge) was removed from the UST and
placed in a tanker truck using vacuum conveyance. Approximately 10 gallons of sludge was
transported under a non -hazardous material manifest by Zebra to their permitted facility in High
Point, North Carolina for treatment/disposal. Sludge manifest records are provided in Appendix
B.
After the tank was cleaned, air in the tank was evaluated by McAdams using a multi -gas meter
with a photoionization detector (PID) sensor. Volatile organic compound (VOC) measurements

were recorded as being less than 0.5 parts per million (ppm). The lower explosive level (LEL) was
measured at zero percent. A Durham Fire Marshal's representative was present to observe the
readings and site conditions.
Following approval by the Durham Fire Marshal, JB Currin removed the tank for off -site disposal.
Prior to off -site transport, McAdams observed that no liquids or unacceptable LEL conditions were
present in the tank, and the tank was rendered unusable.
JB Currin excavated heating oil -impacted soil from the tank pit under the direction of McAdams
in general accordance with NCDEQ UST Section Guidelines (2018) and the approved EMP. Soil
was loaded into trucks for off -site disposal.
Following excavation activities, excavation sidewall and base soil samples were collected for
analysis by on -site mobile laboratory RedLab of Wilmington, North Carolina (RedLab). RedLab,
screened soil with an ultraviolet fluorescence (UVF) QED analyzer to evaluate total petroleum
hydrocarbon (TPH) gasoline range organics (GRO), TPH diesel range organics (DRO), and total
benzene, toluene, ethylbenzene and xylenes (BTEX) concentrations. Soil with detections of TPH
and/or BTEX above UST Section Action Levels was excavated for off -site disposal. Tabulated
UVF — QED Analyzer soil sample results for the last set of samples collected from sidewalls
(EXN-14, EXW-15, EXS-16 and EXE-17) and the base (EXB-13 and EXB-18) of the excavation
are provided in Table 1. RedLab analytical reports are included in Appendix C. A depiction of
the approximate location of UVF samples and the size, shape and orientation of the excavation are
provided in Drawing 4.
The UVF-QED Analyzer soil sample (EXS-16 [8']) with the highest remaining TPH GRO/DRO
concentration (below UST Action Levels) (Drawing 3) was also submitted for confirmation
analysis of VOCs and SVOCs by U.S. EPA Methods 8260B and 8270D, respectively, by Prism
Laboratories, Inc. located in Charlotte, North Carolina. Soil confirmation data and the laboratory
analytical report are summarized in Table 2 and provided in Appendix C, respectively. As
summarized in Table 3, VOCs or SVOCs were detected below applicable Inactive Hazardous Sites
Branch (IHSB) Preliminary Soil Remediation Goals (PSRGs) or UST Section Maximum Soil
Contaminant Concentration Levels (MSCCs) in soil sample EXS-16(8'). Naphthalene was
reported at an estimated concentration below the laboratory reporting limit (RL) (and the
applicable Residential and Protection of Groundwater/Soil-to-Water PSRGs and MSCCs).
The final excavation measured 16 feet in width, 16 feet in length and between 10.5 and 12 feet in
depth (Drawing 4). Saturated sandy silt/clay was encountered in deeper (12 feet below land
surface [BLS]) portions of the excavation. Field observations indicated that the water table was
encountered at approximately 11.5 feet BLS. With the exception of EXB-18, samples were

representative of unsaturated soils. Base excavation soil screening sample results for EXB-13
collected at 10.5 feet BLS and EXB-18 collected at 12 feet BLS (Table 1) indicated the potential
for heating oil to have migrated into the water table. Impacted saturated soils (i.e. soils below the
water table), were over -excavated until QED analysis indicated concentrations below associated
Action Levels. Subsequent groundwater assessment (Section 4.0) conducted in the UST
excavation in April 2019 indicated that no free product was present and VOCs, SVOCs, and metals
were below applicable 15 A North Carolina Administrative Code 02L Groundwater Standards (2L
Standards), UST Section Gross Contaminant Levels (GCLs) and/or Division of Waste
Management (DWM) Vapor Intrusion Groundwater Screening Levels (VI GWSLs).
Approximately 247.26 tons of heating -oil -impacted soil were transported under non -hazardous
waste manifest by JB Currin to Earthtec Environmental (Earthtec) located in Bear Creek, North
Carolina for land farm disposal as part of UST closure activities. Soil weight tickets from the
Earthtec receiving facility are presented in Appendix B.
At the conclusion of UST closure activities, the excavation was backfilled with soil from the
subject site.
No new/unidentified USTs or other impacted soil source areas were identified during construction
soil disturbance activities.
4.0 GROUNDWATER ASSESSMENT ACTIVITIES
In the spring of 2019, McAdams conducted a groundwater assessment (McAdams, 2019b) that
included the installation of three temporary wells (Drawings 2 and 3). This assessment was
performed at the request of the NCBP to evaluate if a documented regional chlorinated solvent
plume was migrating onto the subject site. As summarized in Table 3 and depicted on Drawing
2, a detection of tetrachloroethylene (PCE) was reported in a temporary monitoring well (TW-2)
above the respective 2L Standard), but below the NCDEQ Residential GWSL and GCL. TW-2
was located in the southern portion of the site where a landscaped area is planned for construction.
Groundwater impacted by PCE appeared to be associated with the documented regional
chlorinated solvent plume. No VOCs, SVOCs or metals were detected in groundwater above
applicable 2L Standards, VI GWSLs or GCLs in the temporary well TW-3 installed in the former
UST over -excavation area. Chromium was detected slightly above the 2L Standard (but below
the GCL) in a duplicate sample (only) collected from temporary well TW-1 installed near the
footprint of the new mixed -use structure and the eastern property boundary. The detection of
chromium is likely being attributable to naturally occurring subsurface conditions.

Property are depicted on the figure presented as Drawing 5.
6.0 FINDINGS, CONCLUSIONS, AND RECOMMENDATIONS
The following UST Closure activities were performed in general accordance with the approved
2017 EMP and UST Section Guidance:
• Oversight of UST closure activities including the excavation and removal of approximately
247.26 tons of heating oil -impacted soils from the former UST area. Heating -oil impacted

soil was disposed of at the Earthtec land farm facility located in Bear Creek, North
Carolina.
• Soil UVF-QED Analyzer field screening and laboratory confirmation sampling from the
former UST excavation area indicate that UST excavation activities were effective in
removing heating oil -impacted source area soils to levels below applicable TPH Action
levels, and, Residential and Protection of Groundwater/Soil-to-Water PSRGs and MSCCs.
• Field observations during UST closure activities indicated the presence of the water table
at a depth of approximately 11.5 feet BLS in the tank pit. Field soil screening and mobile
lab sample results indicated the potential for heating oil to have migrated into the water
table. Based on this information, impacted soil below the water table was over -excavated.
Data from the subsequent April 2019 groundwater assessment indicated that no free
product was present in temporary well TW-3, installed in the former UST tank over -
excavation area. Additionally, VOCs, SVOCs and metals were reported below applicable
2L Standards, GCLs and/or VI GWSLs in the groundwater sample collected from TW-
3. This information indicates that no groundwater impacts exist associated with the former
UST.
• Field observations during construction soil disturbance activities indicated no evidence of
other USTs or other impacted soil source areas on the site.
Based on UST Closure soil data and subsequent 2019 groundwater assessment data, no soil or
groundwater impacts remain at the site associated with the former UST and no additional
assessment is planned. Geosyntec concludes that there is no unacceptable risk associated with the
UST Closure and that no further action is warranted.
