B.3. Non -UST Information
There are no other DST's, AST's, piping and dispensers located on the site. There are no historical
compliance issues.
B.4. Release Information
On November 11, 2020, the general contractor was installing drilled piers for the foundation of a
new building. In one of the piers, groundwater was encountered, and a petroleum odor was
detected. On November 12, 2020, SUMMIT personnel collected two (2) soil samples from the drill
cuttings and one (1) sample of the groundwater.
Based on the results of the analytical testing, the groundwater is contaminated with petroleum
products above the NCDEQ's 2L Groundwater Quality Standards. The contractor altered their
methods for drilling the piers to avoid encountering the groundwater for the remainder of the
project.
B.S. Site Characteristics
The United States Geological Survey (USGS) "Concord, North Carolina, United States"
topographic quadrangle map was reviewed. According to the contour lines on the topographic
maps, the elevation of the subject site is approximately 710 feet above Mean Sea Level (MSL). The
inferred groundwater flow direction based on topography appears to be to the east towards an un-
named creek. The un-named creek flows into Threemile Branch. Threemile Branch flows into
Cold Water Creek. Cold Water Creek flows into the Rocky River.
This site contains the soil types:

HA Soil Investigation
SUMMIT Project No. 8177.E0001
January 8, 2021
New, clean disposable latex gloves were used for the collection of each soil sample. Samples
collected for laboratory analyses were placed in laboratory -supplied containers with the sampler's
name, time and date the sample was collected, and laboratory analyses to be performed. The
samples were packed on ice and taken to Pace Analytical Services, LLC in Columbia, South
Carolina.
The soil from the drilled pier location contained the following contaminants:

Definitions of Sources
AST (Tank): means the tank is used to store product
AST Piping: means the piping and connectors running from the tank to the dispenser or other end -use equipment
AST Dispenser: includes the dispenser and the equipment used to connect the dispenser to the piping
AST Delivery Problem: identifies releases that occurred during product delivery to the tank.
OTR Vehicle Tank: means the tank is used to store product to fuel an over the road vehicle
OTR Bulk Transport Tank: means a tank that is used to transport product in bulk over the road (by truck)
RR :bulk Transport Tank: means a tank that is used to transport product in bulk by train
Transformer: means electrical transformer
Other: serves as the option to use when the release source is known but does not fit into one of the preceding categories
Unknown: identifies releases for which the source has not been determined
Definitions of Causes
Spill (Accidental): use this cause when a spill occurs accidentally(e.g., when the delivery hose is disconnected from a fill pipe)
Spill (Intentional): use this cause when a spill occurs intentionally (e.g., intentional dumping or breakage)
Corrosion: use when a metal tank, piping, or other component has a release due to corrosion
Physical or Mechanical Damage: use for all types of physical or mechanical damage, except corrosion
Equipment failure: use when a release occurs due to equipment failure other than corrosion or physical or mechanical damage
AST Overfill: use when an overfill occurs (e.g., overfills may occur from the fill pipe at the tank or when the nozzle fails to shut off at the dispenser)
AST Installation Problem: use when the problem is determined to have occurred specifically because the AST system was not installed properly
Other: use this option when the cause is known but does not fit into one of the preceding categories
Unknown: use when the cause has not been determined
Guidance: Ownership and Operator Type
Ownership select the category which describes owner of the AST system, bulk transport tank, or other release source
Operator Type select the category which describes the operation in which owner uses the AST system, bulk transport tank, or other release source

Case Narrative
SUMMIT Engineering, Laboratory & Testing, P.C.
Lot Number: VK12046
This Report of Analysis contains the analytical result(s) for the sample(s) listed on the Sample Summary
following this Case Narrative. The sample receiving date is documented in the header information
associated with each sample.
All results listed in this report relate only to the samples that are contained within this report.
Sample receipt, sample analysis, and data review have been performed in accordance with the most
current approved The NELAC Institute (TNI) standards, the Pace Analytical Services, LLC ("Pace")
Laboratory Quality Manual, standard operating procedures (SOPS), and Pace policies. Any exceptions to
the TNI standards, the Laboratory Quality Manual, SOPS or policies are qualified on the results page or
discussed below.
Where applicable, all soil sample analysis are reported on a dry weight basis unless flagged with a "W"
qualifier
If you have any questions regarding this report please contact the Pace Project Manager listed on the
cover page.
RCRA Metals
The following sample was diluted due to the nature of the sample matrix: VK12046-002, VK12046-003.
The LOQ has been elevated to reflect the dilution.
VOCs by GC/MS
Acetone was reported as an estimated value in sample: VK12046-002 and VK12046-003 as the result
was above the upper calibration level. The sample was re -analyzed from the medium level (methanol)
vial, but was not reported due to the result being below the LOQ therefore only the low level was
reported.
Surrogate recovery for the following sample was outside of acceptance limits: VK12046-002. At the first
run the CCV had failed high for Methylcyclohexane and sample had hit for Methylcyclohexane, so the
sample was re -analyzed. This sample was reanalyzed as a low-level soil and there was hit of
Methylcyclohexane. A surrogate associated with Methylcyclohexane passed; therefore, the datum have
been reported.

Hey Michael,
You need to include a receptor survey in the Initial Abatement Action report. The receptor surveys for residential
heating oil tanks goes out to 150'. The site would be low risk if there are no water supply wells with 150'. Low risk sites
can be closed out with a NORP.

Trudy,
I'm following up on this to see what the next step is.
The contractor and county decided not to excavate to the groundwater as to not generate contaminated soils. Do I
need to complete an Initial Abatement Action Report? the contractor and county also would like to know what the
possible next steps are for groundwater monitoring.
Thanks
Michael
