4. SITE HISTORY AND CHARACTERIZATION
The site location and vicinity are shown in Figure 1 and Figure 2. The site and pertinent
features are shown on Figure 3.
On December 17, 1986, the Macon County Health Department reported to NCDENR that
gasoline was noted in Crawford Branch at the intersection of Palmer Street and Maple
Street. On December 18, 1986 and December 22, 1986, NCDENR staff investigated the
site and found gasoline seeping into a culvert across Maple Street from the Palmer Street
Texaco. Tank tightness test were performed on the three (3) 10,000-gallon USTs and
none of the USTs passed the test.
On March 7, 1987, the USTs were replaced with three (3) new steel tanks; two (2) 8,000-
gallon USTs and one (1) 6,000-gallon UST. On April 28, 1987 a monitoring well was
installed onsite and petroleum compounds exceeding the 2L Standards were detected.
On April 12, 1990, NCDENR staff investigated the site after receiving a report of
gasoline entering a culvert ditch. Excavation of the UST product lines confirmed a
release from a loose fitting near a dispenser. As a result, five (5) monitoring wells (MW-
1, MW-2, MW-3, MW-4, and MW-5) were installed onsite. The monitoring wells were
sampled in July 1990 and March 1991. Petroleum compounds were detected above the
2L Standards in all of the onsite wells, with concentrations in monitor wells MW-1, MW-
2, and MW-3 exceeding the Gross Contamination Levels (GCLs).
On April 29, 2008, Hart and Hickman (H&H) sampled the onsite monitor wells. MW-1
was gone due to new construction, and MW-5 was filled with mud and could not be
sampled. Contaminant concentrations detected in monitor wells MW-2, MW-3, and
MW-4 had decreased significantly since the March 1991 sampling event. However,
exceedances of the 2L Standards were detected in each of the three onsite monitor wells
with the greatest concentrations detected in monitor well MW-3.
On September 25, 2008 the site was inspected by NCDENR and was reported as being
abandoned. Conversation with the property owner revealed that the USTs had failed their
Cathodic Protection test in June 2007.
Previous assessment activities do not identify water supply wells within 1,000 feet of the
site.
On July 26, 2011, S&ME collected groundwater samples from monitoring wells MW-2,
MW-3, and MW-4. The depth to water was approximately 4 feet below ground surface
(bgs) in each of the monitoring wells. Samples from monitoring wells MW-2 and MW-4
contained several petroleum contaminants less than their respective 2L Standards. No
contaminants were detected a concentrations above the GCLs or the surface water quality
standard by more than 10 times for Class C streams.
On January 5, 6, and 9, 2012, S&ME was on-site to observe the removal of the UST
system (3 USTs) by NEO Corporation (property owner’s contractor). No holes were

observed in the tanks and no evidence of a release was identified in association with the
USTs. Two (2) sets of product piping were observed during removal of the UST system.
S&ME observed removal of only one of the sets of product piping by NEO Corporation.
S&ME observed strong petroleum odors in the soil beneath each of the four (4) product
dispensers. S&ME was not present to observe the over-excavation of the petroleum
impacted soil; therefore, no over-excavation soil samples were collected for laboratory
analysis. Approximately 34 tons of petroleum impacted soil was removed between the
northernmost pump island and monitoring well MW-3 and transported off-site for
disposal.
Total petroleum hydrocarbon (TPH) gasoline range organics (GRO) concentrations
exceeding the NCDENR action level of 10 mg/kg were detected in five of the UST
system closure samples with the greatest concentrations being detected in soil samples
collected in association with the former dispenser islands.
On August 15, 2012, four (4) soil borings were performed using direct push techniques in
the vicinity of the former dispenser islands. Contaminant concentrations exceeding the
Soil-to-Groundwater (STG) Maximum Soil Contaminant Concentrations (MSCCs) but
less than the residential and industrial/commercial MSCCs were detected in each of the
collected soil samples. On August 15, 2012, S&ME observed the installation of
monitoring well MW-1A at the former location of the northernmost dispenser island.
On August 15, 2012, S&ME identified one (1) water supply well located approximately
900 feet southwest of the source area (see Figure 4). The well is located on property
owned by the H.C. Bueck Trustee and addressed as 145 W. Dogwood Drive. Crawford
Branch (a class C stream) in the Little Tennessee River Basin was identified
approximately 30 feet north of the former dispenser island (the nearest source area). The
portion of Crawford Branch immediately north of the subject property is transported via a
culvert; specifically on the properties addressed as 233 W. Palmer Street, 24 Commerce
Street, and 181 W. Palmer Street.
On August 26, 2012, S&ME collected groundwater samples from monitoring wells MW-
1A, MW-2, MW-3, and MW-4. The concentrations of several petroleum compounds in
monitoring wells MW-1A, MW-2, and MW-3 exceeded the 2L Standards but less than
the GCLs. The contamination concentrations generally decreased when compared the
data from the July 2011.
4.1 UST Owner and Operator Information
The subject property has contained two (2) generations of USTs removed in March 1987
and January 2012, respectfully. The former owner/operator of the USTs was Blevins Oil
Company.
4.2 UST Owner and Operator Information
The first generation of USTs was comprised of three (3) 10,000-gallon gasoline USTs
while the second generation of USTs was compromised of two (2) 8,000-gallon gasoline

Depth to and Nature of Bedrock: According to the 1985 USGS Geologic Map of
North Carolina, the site is located in the Blue Ridge Physiographic province.
Bedrock in this area is characterized as biotite gneiss interlayered and gradational
with biotite-garnet gneiss and amphibolite; locally abundant quartz and alumino-
silicates. Depth to bedrock has not been determined.
Depth to Groundwater in Source Area: Depth to groundwater measurements at
the site ranged from 3.61 feet below top of casing (ft-BTOC) in monitoring well
MW-2 to 4.28 ft-BTOC in monitoring well MW-3. Groundwater depth and
elevation measurements are summarized in Table 1.
Direction of Groundwater Flow: Based upon measurements collected on June 26,
2014, groundwater at the site flows generally to the north. Figure 6 graphically
depicts the approximate groundwater flow at the site based upon the June 26,
2014 measurements.
4.5 Owners and Occupants of Adjoining/Nearby Properties and Land

Details regarding the adjacent properties are summarized in Table 2. The land use of the
surrounding area is generally commercial.
4.6 Receptors/Potential Receptor Information
Details regarding water supply wells located within 1,000 feet of the source area are
provided in Table 2 and the location of the water supply well is shown on Figure 4. The
well is located on property owned by the H.C. Bueck Trustee and addressed as 145 W.
Dogwood Drive. The well is located approximately 900 feet southwest of the source
area. The use of the water from the well has not been confirmed. No additional potential
receptors have been noted within 1,000 feet of the source area.
According to the Town of Franklin Water and Sewer (TFWSD), municipal water is
available to properties within 1,000 feet of the site provided by the Town of Franklin. On
October 25, 2012, Mr. Jay Gibson, TFWSD Director, indicated that TCWSD water lines
were present throughout the area within 1,000 feet of the subject property.

5. CURRENT SITE ASSESSMENT INFORMATION
5.1 Current Liquid Levels
On June 26, 2014, S&ME was on-site to gauge liquid levels in monitoring wells MW-1A,
MW-2, MW-3, and MW-4. The depth-to-water ranged from 3.61 feet ft-BTOC in
monitoring well MW-2 to 4.28 ft-BTOC in monitoring well MW-3. Groundwater depth
and elevation measurements are summarized in Table 1. The groundwater elevations
based upon the June 26, 2014, measurements are depicted on Figure 6.
5.2 Groundwater Monitoring Report
After measuring the depth-to-water, S&ME personnel purged each monitoring well with
a disposable polyethylene bailer by evacuating three well volumes or until the well was
dry. After approximately three well volumes the monitoring wells were allowed to
recharge and to allow for settlement of suspended sediment.
After completing the well purging, S&ME personnel collected a groundwater sample
from the monitoring wells. The groundwater samples were placed in laboratory-supplied
containers, stored in a cooler with ice, and shipped under chain-of-custody procedures to
Pace Analytical Services, Inc. (Pace), a North Carolina certified laboratory for laboratory
analysis. The groundwater samples were analyzed for volatile organic compounds
(VOCs) by EPA Method 6200B.
Copies of the monitoring well sampling field forms are included in Appendix I.
Photographs of the site taken on June 26, 2014 are included in Appendix II.
5.3 Summary of Groundwater Assessment Information
The monitoring well sampling results are summarized in Table 3. Review of the
laboratory analytical results for the samples collected on June 26, 2014, indicated
concentrations of benzene greater than the 2L Standards in monitoring wells MW-1A,
MW-2, and MW-3. Naphthalene was detected at concentrations greater than the 2L
Standards in monitoring wells MW-1A, MW-2, and MW-4. Methyl tert-butyl ether
(MTBE) was detected in the sample collected from monitoring well MW-3 at a
concentration exceeding the 2L Standards.
None of the contaminant concentrations were detected at more than 10 times the North
Carolina Surface Water Quality Standard (2B Standards).
Figure 5 graphically depicts the contaminants detected at concentrations above their
respective 2L Standards in the groundwater samples collected. A copy of the laboratory
analytical results is included in Appendix III.
5.4 Regional and Site Geology and Hydrogeology
5.4.1 Soil and Bedrock
The Macon County Soil Survey report suggests that soils underlying the site are part of
the Udorthents-Urban land complex with a 0 to 5 percent slope. According to the 1985
Groundwater Monitoring and Contaminant Transport S&ME Project No. 4305-14-152
Modeling Report - Incident No.5550
Palmer Street Texaco, Franklin, Macon County, NC October 24, 2014

USGS Geologic Map of North Carolina, the site is located in the Blue Ridge
Physiographic province. Bedrock in this area is characterized as biotite gneiss
interlayered and gradational with biotite-garnet gneiss and amphibolite; locally abundant
quartz and alumino-silicates.
5.4.2 Hydrogeology
On June 26, 2014, rising head slug tests were performed on monitoring wells MW-2 and
MW-3. The collected slug test data was analyzed using the Bouwer and Rice Method.
Appendix IV contains the analysis results.
Analysis of the data collected as part of the test at monitoring well MW-2 and MW-3
yielded hydraulic conductivity values of 8.95 x 10-5 centimeters per second (cm/s) and
2.68 x 10-4 cm/s, respectively. The average hydraulic value based on the slug test results
was 1.79 x 10-4 cm/s.
Based upon measurements collected on June 26, 2014, groundwater at the site generally
flows northward with an approximate gradient of 0.05 feet per foot (see Appendix V).
Figure 6 graphically depicts the approximate groundwater flow at the site based upon the
June 26, 2014 measurements.
5.5 Evaluation of Soil and Groundwater Assessment Information
5.5.1 Current Extent and Severity of Contamination
Based on the historic soil sample data obtained via the completion of soil borings in the
vicinity of the former dispenser islands, residual soil exists with concentrations exceeding
the STG MSCCs but less than the residential and industrial/commercial MSCCs. The
extent of the contaminated soil zone is unknown.
Groundwater contamination is currently present in all of the monitoring wells on the
subject property. A comparison of previous groundwater analytical data suggests a
general reduction in contaminant concentration over time. The downgradient extent of
the contamination is unknown but likely intersects Crawford Branch. Because the
immediate downgradient portion of Crawford Branch is encased in a culvert, direct
contact of the shallow groundwater to the Crawford Branch is likely limited.
5.5.2 Cleanup Levels Achieved
Soil (STG MSCCs) No
Groundwater (2L Standards) No

6. CONTAMINANT TRANSPORT MODELING
Fate and transport modeling was used to estimate the impacts of naphthalene on
Crawford Branch. Crawford Branch is located within the Little Tennessee River Basin
and is classified as a Class C stream per the NCDENR Division of Water Resources.
Class C waters are protected for uses such as secondary recreation, fishing, wildlife, fish
consumption, aquatic life, and agricultural. As such, the NCDENR Division of Water
Resources recommends that, for Class C streams, the most stringent 2B Standards
presented for the protection of freshwater and the human health should be used.
Naphthalene was selected as the modeled contaminant of concern as naphthalene was
detected in the sampled monitoring wells at the highest concentration (76.7 g/L at MW-
1A) relative to the respective 2B Standard of 12 g/L for protection of freshwater
aquatic life. Benzene was detected at a maximum concentration of 45.7 g/L in the
groundwater compared to 51 g/L 2B Standard for the protection of human health.
MTBE was detected at a maximum concentration of 115 g/L compared to a NCDENR
2B Standard for the protection of human health of 1,500g/L.
BIOSCREEN was used to predict the concentrations of naphthalene in the groundwater at
the downgradient intersection of Crawford Branch. BIOSCREEN is a software package
developed by the United States Environmental Protection Agency (USEPA) and is used
to simulate the natural attenuation (i.e. natural decay) of petroleum compounds dissolved
in groundwater. The data used for the BIOSCREEN predictive simulation is summarized
in Table 4 and Appendix V and discussed in Section 6.1.
6.1 BIOSCREEN Inputs
The following sections provide a brief description of the inputs for BIOSCREEN.
6.1.1 Hydrogeology
The seepage velocity value was entered based on the finding discussed in Section 5.4.2.
The seepage velocity calculations are included in Appendix V.
6.1.2 Dispersion
Dispersion is a term used to describe the dilution of contaminants as it mixes with
uncontaminated groundwater during migration. Dispersion effects will cause the plume
to spread in the horizontal, transverse, and vertical directions and will essentially dilute
the concentration of the contaminant. Dispersion effects are quantified using
dispersivity, which is multiplied by the seepage velocity of the groundwater. Dispersivity
can be estimated using length of the contaminate plume. For modeling purposes, S&ME
assumed that the length of the plume will not exceed the distance from the source area to
Crawford Branch. BIOSCREEN uses the assumed plume length to calculate
dispersivity.
6.1.3 Adsorption
Adsorption occurs when contaminants are sorbed to organics (i.e. carbon) in the soil.
This adsorption effect slows or retards the flow of contaminants. For modeling purposes,
Groundwater Monitoring and Contaminant Transport S&ME Project No. 4305-14-152
Modeling Report - Incident No.5550
Palmer Street Texaco, Franklin, Macon County, NC October 24, 2014
12
S&ME assumes a retardation factor of 1, which assumes that adsorption is not taking
place. Most soils contain organics that will retard the flow of contaminants; therefore,
this assumption provides a higher than expected contaminant concentration as calculated
by BIOSCREEN.
6.1.4 Biodegradation
Biodegradation is the process by which hydrocarbons are degraded by naturally occurring
microorganisms found in the subsurface. For this modeling effort, S&ME assumed that
1st order decay of the dissolved naphthalene. According to Handbook of Environmental
Degradation Rates, the half-life for naphthalene ranges from 24 hours to 6,192 hours.
For modeling purposes, S&ME used the average of the published values for the half-life
of naphthalene; 3,108 hours or 0.35 year.
6.1.5 General
This section of BIOSCREEN requests information regarding the modeled area, such as
modeled area length and modeled area width. For the modeled area length and width,
S&ME imputed 50 feet and 47 feet (distance from MW-1A to Crawford Branch),
respectively. Following model runs, S&ME determined that the maximum naphthalene
concentration at the interface of the groundwater and the stream occurs approximately 5
to 6 years into the model run.
6.1.6 Source Data
S&ME assumed that the saturated thickness of the contaminant is 25 feet, more than
twice the depth of the monitoring wells on the site. Since most petroleum compounds
reside near the water table surface, this input is conservative.
S&ME assumed that the width of the contaminant at the source area is approximately 50
feet and that the entire width of the contaminant at the source area has a naphthalene
concentration of 76.7 g/L (measured in the sample collected from MW-1A). The
naphthalene concentration of 76.7 g/L was modeled since it represented the greatest
concentration detected from the on-site monitoring wells.
Field observations and groundwater data do not suggest the presence of free product at
well MW-1A. However, for modeling purposes, S&ME assumes that approximately
2000 kilograms (4400 pounds) of Non Aqueous Phase Liquid (NAPL), or free product, is
available as a secondary source to produce additional dissolved petroleum contamination.
The 2000 kilogram value was chosen since BIOSCREEN defaults to a source half-life of
>1,000 years at this value. This assumption will allow BIOSCREEN to predict a higher
than expected contaminant concentration. Again, because free product was not detected
at the site, this input is conservative (overly protective).
6.2 BIOSCREEN Results
Based on the BIOSCREEN simulation, after approximately 3 years, the naphthalene
concentration at the groundwater/stream boundary reaches a steady state concentration of
6 g/L. The BIOSCREEN output is provided in Appendix IV and summarized in Table
4.

7. CONCLUSIONS AND RECOMMENDATIONS
Based on the current and historical assessment information for the site, the following
conclusions are presented:
1. The UST Incident meets the following conditions for a High Risk classification:
a. There is one (1) drinking water supply wells (900 feet SW) within 1,000
feet of the source area. The use of the well is not confirmed. Municipal
water is available to the properties within 1,000 feet of the source area.
b. Contaminant levels in the groundwater exceed the 2L Standards for
benzene, MTBE, and naphthalene in the monitoring wells.
2. Contaminant levels in the samples collected from monitoring wells are generally
decreasing over time.
3. Residual soil exists with concentrations exceeding the STG MSCCs but less than
the residential and industrial/commercial MSCCs in the vicinity of the former

Contaminant transport modeling suggests that the steady-state concentration naphthalene
at the intersection of Crawford Branch would be approximately 6 g/L. The predicted
concentration of naphthalene is equal to the 2L Standard but less than the 2B Standards
for naphthalene; 12 g/L for protection of aquatic life. S&ME performed the modeling
with a conservative approach; specifically when accounting for the model inputs that
were unknown and were assumed. S&ME defines the conservative approach has being in
a manner that would overestimate the resultant naphthalene concentration at the
groundwater/stream interface. Examples of conservative assumptions are provided
below:
The effects of adsorption were assumed to be negligible when in reality most soils
contain organic materials that will indeed retard the migration of contaminants.
An infinite amount of soluable naphthalene mass is available at the source area.
This is believed to be the most conservative assumption since this means that the
source material will always be present and will never degrade.
Considering that the modeling exercise included conservative inputs and the resultant
naphthalene concentration is far below the corresponding surface water quality standards,
the model suggests that migration of the naphthalene contamination from the area in the
vicinity of MW-1A has a low potential to cause impacts to the adjoining stream, as
measured by an exceedance of the surface water standards.
Based on the above, the following recommendations are presented:

1. Determine if the water well 900 feet southwest of the source area is an active or
inactive potable water supply well. If the well is an active potable water supply
well, assess if the user can be connected to municipal water such that the incident
can be reduced from being an NCDENR a High-Risk site to a Low-Risk site.
2. No additional assessment and/or remediation activities in association with the
petroleum-contaminated groundwater are warranted.
3. The site should be eligible for closure under a Notice of Residual Petroleum, if
the incident can be re-classified as Low-Risk.
