4. Description of Release:
No releases have been discovered in connection with the 1,000-gallon gasoline
UST, associated product pump or piping, or anywhere on the project site.
5. Brief Description of Site Characteristics:
The site is part of a 1.707-acre property with the addresses 1500 and 1510
Concord Parkway South in the City of Concord, County of Cabarrus, State of North
Carolina. The location is shown on Figure 1, the pertinent portion of the U.S.
Geological Survey (USGS) 7.5 Minute Topographic Map, Concord Quadrangle.
The southeastern corner of the property is approximately 250 feet northwest of the
intersection of Concord Parkway South and Raiford Drive NW. According to the
Cabarrus County Tax Department, the property is identified by the Property Real
ID 02-028K-0005.00 and N.C. Parcel Identifier Number (PIN) 56107257100000.
The UST and associated dispenser and piping are installed on the western side of
a 1-story 5,384-square-foot concrete -block garage with brick veneer (built in 1982)

formerly occupied by Troutman Motors, Inc. and currently being remodeled into a
Caliber Collision auto body repair/paint shop (See aerial image of site in Figure 4).
Potable water and sanitary sewer services and electricity are supplied to the site
by City of Concord Utilities. The property is zoned General Commercial (C-2)
District under the City of Concord Zoning Ordinance.
According to the USGS 7.5 Minute Series Topographic Map, surface elevations
across the property range from a high of 730 feet above mean sea level (MSL) to
a low of 720 feet above MSL. The ground surface slopes toward the west-
southwest. No surface water is found on the site. Since most of the acreage is
covered by buildings and pavement, surface drainage is afforded via sheetflow
across these impervious surfaces with stormwater runoff captured by drop inlets
installed in the concrete curbing of the parking lot along the southern boundary.
The nearest surface water body and main influence on the direction of surface
water runoff is Wolf Meadow Branch located, at its closest point, about 0.30 miles
to the west-southwest. The inferred path of shallow, unconfined groundwater
movement underneath the site is to the west-southwest since the surficial
groundwater flow direction typically mirrors the topography. However, as the
groundwater percolates downward to the bedrock, it becomes controlled by the
orientation of the rock fracture systems and the direction of the deeper
groundwater flow may not be consistent with the topographic gradients. Monitoring
wells, a well survey with land surface elevations of the wells established, and water
table elevation measurements would be required for a precise determination.
The native soils encountered in the Piedmont Physiographic Province are typically
formed as the residual product of in -place chemical and physical weathering of
underlying parent rocks. According to the Web Soil Survey of Cabarrus County,
North Carolina published by the U.S. Department of Agriculture (USDA) Natural
Resources Conservation Service (NRCS), the type of soil encountered on the
western three -fourths of the property including the UST closure site is Mecklenburg
loam, 2 to 8 percent slopes (MeB), a well -drained and gently -sloping soil on upland
ridges that are dissected by intermittent drainageways. Since the site has been
developed, the soil description should include Mecklenburg -Urban land complex,
2 to 10 percent slopes (MkB) which consists of Mecklenburg soil and Urban land
(Ur) in areas that are too small and intricately mixed to be mapped separately.
The surface layer of Mecklenburg soil typically consists of a dark -reddish -brown
loam 6 inches thick. The subsoil, extending to a depth of 36 inches, is dark -reddish -
brown clay in the upper part, red clay in the middle part, and red clay loam in the
lower part. The underlying material to a depth of 60 inches is mottled yellow, strong

brown, and black saprolite that crushes to sandy loam. Urban land consists of
areas where more than 85 percent of the surface area is covered by asphalt,
concrete, buildings, or other impervious cover. Most of the soil material has been
cut, filled, and graded and the natural characteristics altered or destroyed. The
original landscape, topography, and the drainage pattern have been changed.
C. Closure Procedure
1. Preparations for Closure:
A Notice of Intent: UST Permanent Closure (UST-3 Form) was completed and
mailed to the NCDEQ Wilmington Regional Office over 30 days prior to conducting
closure activities (See photocopy of UST-3 Form in Appendix A and completed
Site Investigation Report for Permanent Closure of Registered UST, UST-213
Form, in Appendix B). As directed by the UST-3 Form, CEC. authorized its closure
contractor, Evo Corporation (Evo), Winston-Salem, NC, to contact the City of
Concord Fire Marshal's Office and obtain the required permit prior to starting
closure activities. Jason Allen, Assistant Fire Marshal, visited the site on the day
of the UST closure and gave his full approval to the performance of the project.
2. Closure Procedure:
On July 22, 2019, Evo mobilized a vacuum truck, a dump truck, and a backhoe to
the project site to perform the UST closure activities. First, the vacuum truck was
used to vacuum all of the residual liquids and accumulated sludge out of the tank.
Next, the vent pipe of the UST, affixed to the building, and the associated dispenser
located next to the tankhold area were removed. Thereafter, the backhoe operator
removed the concrete and asphalt pavement overlying the UST and carefully
excavated the soil covering the tank exposing the fill pipe. The UST was found to
be buried at a depth of approximately 3.5 feet below grade.
The flammable vapors in the tank were made inert by adding solid carbon dioxide
(dry ice) at a rate of 1.5 pounds per 100 gallons of tank capacity. The dry ice was
crushed and distributed evenly over the greatest area. All available tank openings
were open during this procedure and the work area was free from sources of
ignition. An Evo technician tested the tank vapor space by placing the Combustible
Gas Indicator (CGI) probe into the fill opening. Readings were taken at the bottom,
middle, and upper portions of the tank. Each of the readings were 10 percent or
less of the Lower Explosive Limit (LEL) indicating that the tank had been rendered
safe for removal from the ground.

The UST was lifted out of the pit, placed on the ground, and thoroughly examined.
The condition of the UST was found to be good with only moderate rusting and
corrosion observed on the tank. No holes or pitting was discovered in the tank.
3. Storage and Disposal of Residual Material:
According to the Certificate of Disposal (See copy of document in Appendix C), a
total of 25 gallons of non -hazardous sludge contaminated with gasoline was
vacuumed out of the UST into the storage tank of the vacuum truck and was
transported to Evo's approved facility with the address 1703 Vargrave Street,
Winston-Salem, NC for disposal in a manner approved by NCDEQ. The tank was
received by Evo and transported to an approved facility, Foss Recycling, 3459
Thomasville Road, Winston-Salem, NC for proper disposal and recycling (See
copy of Certificate of Tank Disposal in Appendix D).
4, Soil Excavation Activities:
Only the amount of soil necessary to remove the tank was excavated. The
excavation was backfilled with clean overburden and fill soil and compacted.
D. Site Investigation
1. Field Screening:
The soils excavated from the pit were visually and olfactorily screened for the
presence of staining and odors. No staining or odors were detected in any of the
closure samples collected underneath the dispenser or from the bottom of the
excavation underneath the tank.
2. Soil Sampling Information:
On July 22, 2019, at 10:30 hours, following the removal of the product pump, a soil
sample was collected underneath the dispenser at a depth of approximately two
(2) feet into the native soil. At 11:15 and 11:45 hours, following the closure by
removal of the UST, two (2) soil samples were collected at evenly -spaced intervals
approximately two (2) feet into the native soil below the tank at a depth of
approximately 9.5 feet below grade. The three (3) closure samples were collected
using the bucket of the backhoe. The soil samples are identified as follows:

• T1-S: Underneath southern end of UST
• T2-N: Underneath northern end of UST
• D-1: Underneath dispenser
The soil samples were hand -delivered to Prism Laboratories, Inc. of Charlotte, NC
on July 22, 2019 for analysis by U.S. Environmental Protection Agency (EPA)
Method 8015C for total petroleum hydrocarbons (TPH) as gasoline range organics
(GRO) and diesel range organics (DRO) and by EPA Method 8260B for individual
concentrations of benzene, toluene, ethylbenzene, and total xylenes (BTEX).
Tables 1 and 2 contains summaries of the soil sampling results for TPH Action
Levels and BTEX concentrations, respectively. Appendix E contains the complete
laboratory analytical report and chain -of -custody record.
3. Groundwater Sampling Information:
No groundwater was encountered in the bottom of the excavation. Therefore, a
monitoring well and groundwater sampling were not required.
4. Quality -control measures:
Soil sampling guidelines followed during this investigation are found in the
uidelt,,e� fo�c �ainplinq, published by the North Carolina Department of
Environmental Quality (NCDEQ) Division of Waste Management — UST Section
(July 15, 2008 Version and Change 3, Effective December 1, 2013). Pre -cleaned
4-oz sample jars and 40-ml vials containing the prescribed preservatives were
obtained from a North Carolina -Certified laboratory, Prism Laboratories, Inc.,
Charlotte, NC (Certification No. 402) to perform the appropriate analytical
methods. The containers were labeled prior to sample collection, including all
pertinent information, and storage/transport chests were chilled to approximately
4 degrees Celsius prior to taking the samples.
The soil samples were extracted in a manner that caused the least disturbance of
the internal structure of the soil and reduced the exposure to heat, sunlight and
open air. Care was taken to keep the samples from being contaminated by other
material at the site or from contaminating the other samples taken from the site.
Disposable nitrite gloves were worn by the sample collector and were changed
between samples to avoid cross -contamination. Immediately upon removal from
the ground, the samples were placed in the proper containers for the analysis to
be performed. The soil samples filled the entire volume of the jars with no
headspace as required by the designated analytical method.

WILMINGTON, NC
As soon as the samples were collected the containers were immediately capped,
sealed, and stored for transport in a manner to prevent breakage. The samples
were kept at a temperature of approximately 4 degrees Celsius, adding the
necessary ice following collection. The chain -of -custody was filled out completely
and accompanied the samples as they were hand -delivered o Prism Laboratories.
5. Soil Investigation Results:
According to the laboratory report of analysis, the results for confirmation soil
samples T1-S, T2-N, and D-1 collected underneath the UST and related product
pump were all "below reporting limit" (BRL).
E. Conclusions and Recommendations
The analytical results for the confirmation samples collected underneath the UST
and related dispenser were all "below reporting limit" (BRL). No free product was
present. No bedrock or groundwater was encountered in the excavation. Since the
tank removal is a clean closure, no further action is requested for the site.

INSTRUCTIONS (READ THIS FIRST)
Complete and return at least thirty (30) days prior to closure or change -in-service activities. If a Professional Engineer (P.E.) or a Licensed Geologist (L.G.)
provides supervision for closure or change -in-service site assessment activities and signs and seals all closure reports then at least a five (5) working
days notice is acceptable.
Completed UST closure or change -in-service site assessment reports, along with a copy of the UST-2 form, should be submitted to the appropriate Division
of Waste Management (DWM) Regional Office within thirty (30) days following closure activities. The UST-2 form should also be submitted to the Central
Office in Raleigh so that the status of the tanks may be changed to permanently closed and your tank fee account can be closed out. Note: Tank fees may
be due on unregistered tanks.
UST closure and change -in-service site assessments must be completed in accordance with the latest version of the Guidelines for Site Checks, Tank
Closure and Initial Response. The guidelines can be obtained at http://www.wastenotnc.org/. Note: To close tanks in place you must obtain prior approval
from the DWM Regional office located in the region where the facility is located.
You must make sure that USTs removed from your property are disposed of properly. When choosing a closure contractor, ask where the tank(s) will be
taken for disposal. Usually, USTs are cleaned and cut up for scrap metal. This is dangerous work and must be performed by a qualified company. Tanks
disposed of illegally in fields or other dumpsites can leak petroleum products and sludge into the environment. If your tanks are disposed of improperly, you
could be held responsible for the cleanup of any environmental damage that occurs.

Good Morning Ms. Beverly,
Please find the attached UST Closure Report on the site in Concord, NC we previously discussed. The analytical
results indicate the tank removal is a clean closure.
Let me know if you require a hard copy of the report. I deal with the Wilmington Regional Office primarily and they
currently only require electronic copies.
Thank you,
