B: EXECUTIVE SUMMARY
The subject property is located at 913 Ridgecrest Drive in Greensboro, Guilford County,
North Carolina. The area of concern is the former underground storage tank (UST) pit on the southeast
side of the residential structure. One approximately 550-gallon, bare-steel heating oil UST, installed at an
unknown date, was removed from the subject property on August 10, 2020. One soil sample was collected
from the base of the excavated area and submitted to a laboratory for chemical analysis. The soil sample
associated with the Heating Oil UST system was not above applicable action levels for soil contamination.
The soil sample analyzed did not exceed the action level for North Carolina Department of Environmental
Quality (NC DEQ) Residential Maximum Soil Contamination Concentrations (MSCCs) or NC DEQ Soil-
to-groundwater MSCCs. Excavation of soil, other than what was necessary to remove the UST, was not
conducted due to no signs of a release.
The approximate coordinates of the former UST are 36.093331, -79.894639. Site reconnaissance during
the closure activities did not identify any private use water wells within 150 feet of the UST excavation.
The subject property is located in a mixed-use area. The approximate site location and UST pit location are
shown on Figures 1, 2, and 3.

D: SITE HISTORY AND CHARACTERIZATION
1. UST Owner/Operator Information:
The former UST owner/operator and dates of operation is unknown. The Presbyterian Homes Inc
currently owns the property.
2. UST Information:
The last known contents of the UST were heating oil used for residential heating purposes. The tank
was of bare steel construction and approximately 550-gallons in capacity. The UST was removed from
the ground on August 10, 2020. A tank disposal manifest is included in the Appendix.
3. Non-UST Spills at the Site:
No non-UST spills are known to have occurred at the site.
4. Description of Release:
The UST system was discovered during an Environmental Transaction Screen performed in July of
2019, and the UST was removed from the ground on August 10, 2020. During the removal of the UST,
the UST appeared to be in good condition with no visible leaks.
5. Site Characteristics:
The subject site, located at 913 Ridgecrest Drive, is currently vacant. The site formerly housed a
residential structure that was previously demolished. The surrounding properties are residential. The
area surrounding the residence is mostly grassed.
The subject site is located in the Piedmont Physiographic Province of North Carolina. Based on review
of the Geologic Map of North Carolina, 1985, the site is located in the Charlotte Belt of the Piedmont
Geologic Province of North Carolina. Soils in this area have been formed by the in-place weathering
of the underlying crystalline rock, which accounts for their classification as “residual” soils. Residual
soils near the ground surface, which have experienced advanced weathering, frequently consist of red
brown clayey silt (ML) or silty clay (CL). The thickness of this surficial clayey zone may range up to
roughly 6 feet. For various reasons, such as erosion or local variation of mineralization, the upper
clayey zone is not always present.
With increased depth, the soil becomes less weathered, coarser grained, and the structural character of
the underlying parent rock becomes more evident. These residual soils are typically classified as sandy
micaceous silt (ML) or silty micaceous sand (SM). With a further increase in depth, the soils eventually
become quite hard and take on an increasing resemblance to the underlying parent rock. When these
materials have a standard penetration resistance of 100 blows per foot or greater, they are referred to as
partially weathered rock. The transition from soil to partially weathered rock is usually a gradual one
and may occur at a wide range of depths. Lenses or layers of partially weathered rock are not unusual
in the soil profile.
Partially weathered rock represents the zone of transition between the soil and the indurated
metamorphic rocks from which the soils are derived. The subsurface profile is, in fact, a history of the
weathering process which the crystalline rock has undergone. The degree of weathering is most
advanced at the ground surface, where fine grained soil may be present. And, the weathering process
is in its early stages immediately above the surface of relatively sound rock, where partially weathered
rock may be found.

Project Number 190474.10
November 23, 2020 │ 7
The thickness of the zone of partially weathered rock and the depth to the rock surface have both been
found to vary considerably over relatively short distances. The depth to the rock surface may frequently
range from the ground surface to 80 feet or more. The thickness of partially weathered rock, which
overlies the rock surface, may vary from only a few inches to as much as 40 feet or more.
Groundwater in the Piedmont is typically found in two separate but interconnected water-bearing zones.
A shallow water-bearing zone is typically found in the residual soils layer. A deeper water-bearing zone
occurs within the underlying bedrock. Groundwater was not encountered during excavations at the
subject site.
Topography at the subject site generally slopes down to the west-northwest. Surface water bodies are
not present at the subject site. No water supply wells were observed on the subject property or adjoining
properties. Review of the Guilford County GIS website for wells in the area of the subject site did not
reveal any wells with 1,000-feet from the subject site.
6. Initial Abatement Actions, Assessment Activities, and Corrective Actions:
Geo-Hydro was contracted by The Presbyterian Homes Inc to provide UST system removal, soil
sampling, and reporting services. Presbyterian Homes, Inc. contracted Doggett Construction to perform
the UST removal activities. The heating oil UST was removed from the ground on August 10, 2020.
Field screening with a photoionization detector (PID) was performed by Geo-Hydro during removal
and excavation activities. Based on the results of field screening procedures, over-excavation was not
conducted. Excavation of soil, other than what was necessary to remove the UST, was not conducted
due to no obvious signs of a release. A soil sample was collected and submitted for laboratory analysis
from the base of the excavation in general accordance with NC DEQ UST STIRA Guidelines.
E: CLOSURE PROCEDURE
1. Preparations for Closure:
Based on the UST being a Non-Regulated, Noncommercial UST, a UST-3 Form was not submitted to
the NC DEQ UST Section prior to closure activities. The tank was purged of liquid and sludge material
via vacuum-truck and rendered inert with dry ice after purging.
2. Closure Procedures:
Overburden soils on the top and sides of the UST were excavated until the tank could be removed.
The UST was then removed with a track-mounted excavator. After removal, the tank was inspected for
holes, corrosion, and pitting. The tank was determined to be in good condition. No impacted soils were
observed below the tank. Due to no visible signs of a release and continuous screening of soil by PID
excavation was stopped at approximately eight feet below ground surface. One sample was collected
beneath the tank to a depth of 8.5 feet.
Due to the heating oil contents, the UST pit base sample was submitted for laboratory analysis for
volatile organic compounds (VOCs) via USEPA Method 8260B, semi volatile organic compounds
(SVOCs) via USEPA Method 8270D, total petroleum hydrocarbons-gasoline range organics
(TPH-GRO), TPH-DRO, MADEP EPH, and MADEP VPH analysis.
Excavated soil was loaded directly into dump trucks during excavation activities. Approximately 17.05
tons of soil were excavated from the UST pit and transported to AES of North Carolina, a permitted
Soil Treatment Facility, located in Thomasville, North Carolina. The tank pit was backfilled with clean
Friends Homes – Ridgecrest, 913 ● Greensboro, Guilford County, North Carolina
Project Number 190474.10
November 23, 2020 │ 8
soil fill material that was brought in from offsite and was compacted with the excavator bucket during
backfill activities. Soil disposal waste manifests are included in the Appendix.
3. Residual Material in UST:
At the time of removal, the 550-gallon UST contained no residual material.
4. Soil Excavation Activities:
After removal of the UST, the base of the excavation was approximately three feet below ground
surface. Excavated soil was loaded directly into dump trucks during excavation activities.
Approximately 17.05 tons of soil were excavated from the UST pit and transported to AES of North
Carolina, a permitted Soil Treatment Facility, located in Thomasville, North Carolina. The tank pit
was backfilled with clean soil fill material that was brought in from offsite and was compacted with the
excavator bucket during backfill activities. Soil disposal waste manifests are included in the Appendix.
F: SITE INVESTIGATION
1. Field Screening:
Post-removal soil sampling was conducted at the base of the tank pit. Soil screening was performed in
the field by placing a soil grab sample in a Ziploc bag and screening the headspace of the bag with a
PID. Based on field screening observations, over-excavation was not necessary at the time of removal,
but was conducted. Side walls were also screened continuously during the excavation. Calibration of
the PID was performed by the rental provider, Enviro-Equipment, Inc.
Soils in the tank pit were classified in the field as sandy silt.
2. Soil Sampling Information:
A grab soil sample was collected from the base of the tank pit from the excavator bucket. The soil
sample was collected into a Ziploc bag, screening the headspace of the bag with a PID, and then
immediately sampled by collection in laboratory supplied sample containers.
3. Groundwater and Surface Water Sampling:
Groundwater and surface water were not encountered at the subject site.
4. Quality Control Procedures:
The soil sample was placed on ice immediately following collection and transported under standard
chain-of-custody procedures to Pace Analytical of Huntersville, NC. A clean pair of nitrile gloves was
worn for collection and handling of the sample.
5. Investigation Results:
Soil sampling results, outlined in Table A, indicated that the soil sample associated with the UST does
not exceed applicable NC DEQ UST Soil-to-Groundwater Maximum Soil Contaminant Concentrations
(MSCCs).
Soil sampling results, outlined in Table A, indicated the soil sample collected beneath the UST, 913
Ridgecrest (Base), contained TPH-DRO concentration at 10.4 milligrams per kilogram (mg/kg), below
the Soil-to-Groundwater MSCC and Residential Soil MSCC of 100 mg/kg. Also outlined in Table A,
naphthalene, a VOCs was detected; however, this detection did not exceed the Soil to Groundwater or
Residential MSCC action level of 0.16 and 313 mg/kg respectively, for naphthalene. Soil sampling
results, outlined in Table B, indicated the soil sample collected beneath the UST, 913 Ridgecrest (Base),
Friends Homes – Ridgecrest, 913 ● Greensboro, Guilford County, North Carolina
Project Number 190474.10
November 23, 2020 │ 9
contained MADEP VPH and EPH C9-C18 Aliphatics concentrations at 14.2 mg/kg ; however, this
detection did not exceed the Soil to Groundwater or Residential MSCC action level of 540 and 1,500
mg/kg respectively, for C9-C18 Aliphatics. Semi-volatile organic compounds (SVOCs) were also
requested to be ran on the soil sample and did not exceed the laboratory’s method detection limit.
G: CONCLUSIONS AND RECOMMENDATIONS
The heating oil UST closure procedures outlined in this report were performed in accordance with the
NC DEQ Guidelines for Site Checks, Tank Closure, and Initial Response and Abatement for UST Releases
document. No detections were above NC DEQ action levels of MSCCs.
Based on the results of soil analysis of the post-removal soil sample related to the UST, Geo-Hydro
Engineers requests the NC DEQ consider issuing a No Further Action determination for the UST system at
913 Ridgecrest Drive in Greensboro, Guilford County, North Carolina.

DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL - Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean-Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.

ANALYTE QUALIFIERS
Sample was diluted due to the presence of high levels of non-target analytes or other matrix interference.D3
The precision between the sample and sample duplicate exceeded laboratory control limits.D6
The recalculated concentration of the calibration standard(s) did not meet method acceptance criteria; this result should
be considered an estimated value.IK
Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.M1
The lab does not hold NELAC/TNI accreditation for this parameter but other accreditations/certifications may apply. A
complete list of accreditations/certifications is available upon request.N2
Surrogate recovery not evaluated against control limits due to sample dilution.S4
Surrogate recovery outside control limits due to matrix interferences (not confirmed by re-analysis).S5
The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the
associated samples may have a high bias.v1
The continuing calibration verification was below the method acceptance limit. The analyte was not detected in the
associated samples and the sensitivity of the instrument was verified with a reporting limit check standard.v2
The continuing calibration verification was below the method acceptance limit. Any detection for the analyte in the
associated samples may have low bias.v3
