1.0 EXECUTIVE SUMMARY

In summary, two (2) groundwater samples were collected from locations on-site identified to
represent the highest potential for impact from the operation of a former auto repair facility and
associated underground storage tank system. Three (3) sampling locations were planned for this
assessment, however utility conflicts and current tenant conflicts limited the installation of to
TMW-1 and TMW-3 only. This sampling scope of services was completed to determine if former
site uses may have impacted the subject site. All groundwater samples were analyzed for the
presence of Volatile Organic Compounds (VOCs) by EPA method 8260 and Semi-Volatile Organic
Compounds (SVOCs) by EPA method 8270.

Tetrachloroethene (aka PCE) was detected in groundwater collected from sampling point TMW-3 at
16 ug/L, above the regulatory concentration of 0.7 ug/L. Tetrachloroethene is a chlorinated solvent
commonly utilized in automotive degreasers, cleaners and dry cleaning chemicals.

Based on the results of this assessment, SUMMIT concludes that the site use as a former auto
repair facility has impacted the site.

SUMMIT recommends the potential developer of the property consider entry into the North
Carolina Department of Environmental Quality (DEQ) Brownfields Program. The program can be
utilized to further assess the property and provide liability protections to the developer and future
owners of the site. The Brownfields Program will require additional soil, groundwater and soil
vapor sampling to be conducted at the site parcels in order to assess current environmental status.

A copy of the Limited Phase II ESA analysis and subsequent confirmation sampling should be
submitted to North Carolina Department of Environment Quality.

2.0 INTRODUCTION
2.1. PURPOSE

SUMMIT was retained by Tribek Properties to perform a Limited Phase II ESA of the E. Innes
Street Property in Salisbury, Rowan County, North Carolina (Rowan County Tax IDS: 0700301,
070118 & 070002). The Limited Phase II ESA was requested in order to assess environmental
concerns identified in a Phase I ESA, performed by SUMMIT ELT, Inc, dated December 12, 2015.
This report presents the results of our Limited Phase II ESA of the Pecan Avenue Site.

2.2. SITE DESCRIPTION

The property includes three (3) parcels of commercial land located at 1517, 1535 and 1541 E. Innes
Street in Salisbury, Rowan County, North Carolina. There are two (2) commercial buildings on the
site. The building on parcel 070002 was formerly utilized as an automobile repair operation. The
parcels are irregular-shaped. Refer to the Site Plan shown in Figure 2 of Appendix I for the location
of the subject property.

2.3. ASSESSMENT HISTORY

SUMMIT completed a Phase I ESA, dated December 12, 2015 for the subject site. The following
Recognized Environmental Conditions (RECs) were identified in the Phase I ESA:

• The subject site previously contained one (1) Underground Storage Tank (UST) on the
northern portion of the property. The EDR report indicates the UST was removed in
1979. Additionally, the property was previously used as an automobile maintenance
facility. There are floor drains along the western portion of the building. SUMMIT
recommends additional environmental assessment to determine if the previous activities
have impacted the property.

No other site specific or surrounding area assessment history is known at the time of this report.

2.4. WORK PLAN OBJECTIVES

SUMMIT proposed to perform a Limited Phase II ESA according to our understanding of the most
likely potential for impact, in general accordance with ASTM E1903, and in accordance with the
USEPA Field Branches Quality System and Technical Procedures Manual. The proposed scope of
services included the installation of three (3) temporary monitoring wells (TMW) in order to assess
the groundwater quality at the subject site. The proposed sampling locations were placed in
accessible locations and in areas that represented the highest potential for on-site impacts. All
samples collected f were scheduled to be relinquished to a NC certified laboratory for analysis of
Volatile Organic Compounds by EPA method 8260 and Semi-Volatile Organic Compounds by EPA
method 8270.

3.0 PROPERTY SETTING

3.1. TOPOGRAPHIC SETTING

The United States Geological Survey (USGS) Salisbury topographic quadrangle map was reviewed
for this report. According to the contour lines on the topographic maps, the elevation of the subject
property ranges from approximately 770 feet (along southern property boundaries) to approximately
740 feet (along northern property boundaries) above Mean Sea Level (MSL). The contour lines
indicate the general direction of downward slope is to the north towards Town Creek. Town Creek
flows into High Rock Lake (Tadkin River). Refer to Figure 1 in Appendix I of this report.

3.2. GEOLOGIC SETTING

The property is located in Rowan County, North Carolina, which is located in the central Piedmont
Physiographic Province. The Piedmont Province generally consists of well-rounded hills and
ridges which are dissected by a well-developed system of draws and streams. The Piedmont
Province is predominantly underlain by metamorphic rock (formed by heat, pressure and/or
chemical action) and igneous rock (formed directly from molten material) which were initially
formed during the Precambrian and Paleozoic eras. The volcanic and sedimentary rocks deposited
in the Piedmont Province during the Precambrian era were the host from the metamorphism and
were changed to gneiss and schist. The more recent Paleozoic era had periods of igneous
emplacement, with at least episodes of regional metamorphism resulting in the majority of the rock
types seen today.

The topography and relief of the Piedmont Province has developed from differential weathering of
the igneous and metamorphic rock. Ridges and hills have been developed on the more easily
weathered and erodible rock. Because of the continued chemical and physical weathering, the
rocks in the Piedmont Province are now generally covered with a mantle of soil that has weathered
in place from the parent bedrock. These soils vary in thickness and are referred to as residuum or
residual soils. The residuum is typically finer grained and has higher clay content near the surface

because of the advanced weathering. Similarly, the soils typically become coarser grained with
increasing depth because of decreased weathering. As the weathering decreases, the residual soils
generally retain the overall appearance, texture, gradation and foliations of the parent rock.

3.3. HYDROLOGIC SETTING

Based on a review of the United States Geological Survey (USGS) “Salisbury, North Carolina,
United States” quadrangle topographic map, the inferred groundwater flow direction based on
topography appears to be to the north towards Town Creek. Refer to Figure 1 in Appendix I for a
topographic map for the subject property.

4.0 SUMMARY OF PHASE II ACTIVITIES

4.1. DRILLING ACTIVITES AND METHODS

On January 20, 2016, SUMMIT personnel conducted the field activities scope of the Limited
Phase II ESA. The three (3) proposed temporary monitoring well (TMW) locations were placed in
accessible locations along the northern, eastern and southern elevations of the former auto repair
facility. The sampling locations were chosen to determine if on-site operations may have impacted
the groundwater beneath the facility. The sampling locations can be viewed on the attached
Sampling Location Map, Figure 3, in appendix I.

SUMMIT utilized a hollow stem auger (HSA) drill rig to install the temporary monitoring wells.
At each sampling location the boring was advanced with HSA into the groundwater table for
collection of groundwater samples. New 1 inch slotted well screen was inserted into the borehole
with filter pack sand added through the HSA drill string. The HSA drill string was removed and the
temporary well sampled utilizing a new disposable groundwater bailer. TMW-1 and TMW-3 were
completed to a depth of 30 ft bgs. TMW-2 was not installed due to overhead and underground
utility conflicts along the eastern side of the building. Additional locations along the eastern portion
of the building were considered, however the current tenant would not allow access due to potential
impact on the current restaurant business. DTW was measured in each well prior to sampling.
Each boring generally encountered six (6) inches of surface material and subgrade followed by
tan/orange fine to medium grained clayey sand with mica to termination depths.

Upon completion of the drilling activities, the drilling equipment was decontaminated by the well
driller by use of a steam cleaner or Alconox and tap water wash, tap water rinse, isopropanol rinse
(sampling equipment), and deionized water rinse. Decontamination of the drilling equipment was
performed prior to starting drilling activities, and upon the completion of drilling activities at each
boring/well location.

4.2. SAMPLING

Groundwater was encountered in all installed temporary monitoring wells. The following depth to
water measurements were recorded prior to sampling.

TMW ID DTW FT
TMW-1 26
TMW-2 N/A
TMW-3 24

Groundwater samples were collected utilizing new disposable bailers. Grab samples were collected
in the laboratory provided vials and jars and submitted for analysis of Volatile Organic Compounds
by EPA Method 8260B Polycyclic Aromatic Hydrocarbons by EPA Method 8270. A copy of the
analysis and chains of custody are included in Appendix III of this report.

4.3. PACKING AND SHIPMENT
Upon securing the samples in laboratory provided containers, the vial and jar lids were tightly
fastened, and the jars encapsulated in shock-resistant plastic bags. The samples and ice were
double-bagged in large plastic bags, tied off with rubber bands, and packed into a cooler. The
samples were delivered to Shealy Environmental Services, Inc, in West Columbia, SC. The vials
and jars used for the collection of the samples at this site were prepared by Shealy, and were pre-
labeled and contained analyte-appropriate preservatives. A listing of the preservatives in the sample
containers utilized for the collection of the samples at this site are cataloged in the Chain-Of-
Custody record, attached in Appendix III of this report. The secured samples were relinquished to
laboratory on January 21, 2016 for laboratory analysis.

4.4. SAMPLING POINT ABANDONMENT

All boreholes were abandoned the same day by the certified well driller.
