1.0 INTRODUCTION
Groundwater and Environmental Services, Inc. (GES) has prepared this 2012
Annual Non -Discharge Report (Report) on behalf of RETIA USA, LLC (RETIA), a
subsidiary of TOTAL Petrochemicals & Refinery USA, Inc. (TPRI)', documenting
the operation of the in -situ Thermal Remediation System, using Electro-Thermal
Dynamic Stripping Process (ET-DSPTM) source area treatment technology, for the
former Fina Bulk Fuel Terminal #1760 (the "Site"). The selected source removal
strategy, ET-DSPTM, was proven effective in a pilot study program conducted in
2004. The ET-DSPTM technology was compared with conventional remediation
technologies (i.e., dewatering/high-vacuum extraction test and combined air
sparge/high-vacuum extraction) and selected by RETIA and the Greensboro
Remediation Team (GES, ES&T, ARCADIS, MK Environmental, Lone Wolf
Resources, and McMillan -McGee Corporation) as an appropriate source area
remediation technique for this site. The objective of the source area remediation
technology is to remove as much hydrocarbon mass as possible over a set period of
operational time.
The Site was issued a North Carolina Division of Water Quality (NCDWQ) Non -
Discharge Permit No. WQ0029191 on 8 February 2006, which was subsequently
modified on 19 October 2007 to allow the use of saline amendments to increase
electrical conductivity of the soil immediately surrounding the operational
electrodes An additional permit modification request was made on 5 August 2009
to change the removal percentage for tert-butyl alcohol (TBA) from 95% to 85%.
This permit was issued for operation of the ET-DSPTM system in conjunction with a
groundwater and soil vapor treatment plant constructed at the Site. The source area
remediation system was constructed in accordance with the Source Area Removal
Work Plan (Work Plan) (GES, August 2005) submitted to the Guilford County
Department of Health and the North Carolina Department of Environment and
Natural Resources (NCDENR). The Work Plan was approved by NCDENR in a
letter dated 12 October 2005.
As indicated in the Work Plan, the source area was divided into four (4) treatment
zones (herein referred to as Zones 1, 2, 3, and 4). Figure 1 presents a full site map
and Figure 2 presents the remedial treatment zone site plan. Operation of Zone 1
began the week of 15 March 2007, and was completed on 4 October 2007. A
summary of Zone 1 operations was provided as part of the 2007 Annual Report
(GES, April 2008). Operation of Zone 2 began the week of 3 March 2008 and
continued until 22 April 2009. A summary of the Zone 2 operations was provided
as part of the 2008 and 2009 Annual Reports (GES, April 2009 and 2010).
Operation of Zone 3 began 4 September 2009 and continued until 19 July 2010. A
summary of the Zone 3 operations was provided as part of the 2009 and 2010
Annual Reports (GES, April 2010 and 2011).
Operation of Zone 4 began on 17 November 2010 with vapor extraction only and
continued throughout the remainder of 2010. Due to the inclement weather
GES — June 2013-Revision 1 1 RETIA (Former TOTAL SITE # 1760)

(freezing conditions and temperatures below 26 °F), full startup and shakedown
testing, including vapor and groundwater extraction/injection began on 20 February
2011 and continued operation through 26 September 2012. The Zone 4 operations
originally utilized a network of 78 extraction wells (61 wells which are multi -phase
extraction wells, and 17 wells which are vapor extraction wells), 38 single
electrodes, 78 double -stacked electrodes, 35 temperature monitoring points
(digiTAMsTM), 15 combination temperature and pressure monitoring points
(digiTAMSTM and digiPAMSTM), 10 vacuum monitoring points and 10 piezometers.
In December 2011, seventeen (17) additional multi -phase extraction wells were
added and one multi -phase extraction well was replaced to supplement the existing
recovery well network in order to optimize recovery. In May 2012, five (5)
additional multi -phase extraction wells were added to enhance and optimize
recovery during the fmal months of operation. After the installation of the five (5)
additional wells, the Zone 4 heating operations targeted those areas where
monitoring data suggested that there was residual mass remaining. This modus
operandi continued until operations ceased in September 2012.
During operation, heated groundwater and soil vapors were extracted from the
extraction wells and vapor points through an above -grade piping system and
transferred to the treatment plant. Groundwater treatment equipment included the
following primary components for removal of petroleum -related hydrocarbons: (1)
oil -water separator, (2) air stripper tower, and (3) activated carbon vessels.
Following treatment, the groundwater was re -injected back into the subsurface
through the electrodes. Heated soil vapors were treated utilizing a thermal oxidizer,
and discharged to the atmosphere in accordance with the North Carolina Division
of Air Quality (NCDAQ) Permit Number 09563R00.
The remediation system was monitored daily via on -site operators and/or telemetry
systems to confirm proper operation within the requirements of the aforementioned
permits. The following sections of this report provide further detail regarding the
Zone 4 operations in order to maintain compliance with the Non -Discharge Permit
No. WQ0029191.
— In 2004 the company changed its name to TOTAL Petrochemicals USA, Inc. In January 2012, following a global
restructuring, its name changed to TOTAL Petrochemicals & Refining USA, Inc (TPRI). RETIA USA, LLC is a subsidiary of
TPRI with specific responsibility for remediation and risk management activities at former and current TPRI sites

2.0 SUMMARY OF ZONE 4 OPERATIONS
As discussed previously, Zone 4 source zone removal operations began on 20
February 2012 and ended on 26 September 2012. The majority of the Zone 4
construction (well/electrode/sensor installation and piping network assembly) was
conducted from 08 August 2010 to 15 October 2011. Supplemental construction
(recovery well installation) also occurred from November 21 to December 9, 2011
and from April 30 to May 9, 2012. The following sections describe the Zone 4
operations in 2012.
2.1 HYDRAULIC BALANCE
2.1.1 Influent Flow Rates vs. Effluent Flow Rates
The influent and effluent flow rates for the treatment plant were recorded daily in
order to maintain a balanced ratio of extracted to injected groundwater for Zone 4.
A totalizing flow meter located immediately downstream of the oil/water separator
was utilized to monitor the influent flow rates (FQI #1). The effluent flow rates
were monitored using a second totalizing flow meter following the last treatment
stage (i.e., carbon vessels) and prior to injection (FQI #4).
The water flow rate to the electrodes was monitored at each of eight (8) water
recirculation units located in the well field during Zone 4 operations. These water
recirculation units received treated water from the Plant and distributed the water to
each individual electrode utilizing a dedicated pump, solenoid valves, and various
lengths of/< -inch tubing. Potable water was also added to supplement the treated
water if required. The average injection pressure at the dedicated pump (prior to
the %-inch tubing) was 70 psi during Zone 4 operation.
The electrodes were constructed with V4-inch injection lines that feed the 10-inch-
diameter electrode chambers, which resulted in a large decrease in pressure once
the water reached the electrodes. The actual pressure of the water leaving the
electrodes was closer to atmospheric pressure within the vadose zone and slightly
higher than the hydrostatic pressure for electrodes within the saturated zone.
The average groundwater extraction rate from January 2012 through September
2012 was approximately 22 gallons per minute (gpm); the average injection rate
was approximately 19 gpm (average ratio of 1.2:1). The difference in volumes was
accounted for through evaporation within the treatment plant and through
discharges to the sanitary sewer system. The plant was issued Special Discharge
Permit Number S2038 from the City of Greensboro, which allowed up to 10,000
gallons of treated water per day to be discharged to the sewer. When injection to
the Zone 4 electrodes was not required (i.e., ET-DSPTM system not operational), the
GES — June 2013-Revision 1 3 RETIA (Former TOTAL SITE # 1760)

treated groundwater was discharged to the sewer in accordance with Permit No.
S2038.
2.1.2 Groundwater Elevation Monitoring
The 15 combination temperature and pressure monitoring points in Zone 4 (Z4-TP 1
through Z4-TP15) were equipped with digital pressure sensors (digiPAMSTM) that
measured the groundwater levels across Zone 4 without the need for physical
access to the subsurface (see Figure 3). These data were automatically relayed to a
database maintained by McMillan -McGee Corporation, and were utilized to
monitor potentiometric levels within the well field and to confirm the hydraulic
gradient and flow direction across the site. Each of the sensor points was
periodically gauged with an electronic oil -water interface probe to check the
calibration of the digiPAMSTM.
Baseline (October 2010) and Completion (September 2012) groundwater gauging
data were used to construct groundwater contour maps which are included as
Figures 4 and 5, respectively. The Zone 4 data suggest that the gradient was
manipulated by the extraction system. The overall change in groundwater flow,
compared with the overall extraction to injection ratio of 1.2:1 mentioned above,
suggests that the extraction network maintained hydraulic control of Zone 4. The
Zone 4 groundwater contours were monitored daily via real-time digiPAMTM data
generated on the McMillan -McGee Corporation website and extraction rates were
adjusted accordingly.
2.2 INJECTION PERMIT COMPLIANCE SAMPLES AND WELL -FIELD
DATA RESULTS
2.2.1 Summary of Monthly Influent and Effluent Sampling Events
Per the monitoring requirements of Non -Discharge Permit No. WQ0029191, the
influent and effluent from the Plant were sampled each month during Zone 4
operations for the following site -specific contaminants of concern:
• Benzene
• 1,2-Dibromoethane
• 1,2-Dichloroethane
• Ethylbenzene
• 4-Isopropyltoluene
• Naphthalene
• Tert Butyl Alcohol
• Toluene
GES — June 2013-Revision 1 4 RETIA (Former TOTAL SITE # 1760)

• Xylenes
• 1,2,4-Trimethylbenzene
• 2-Methylnaphthalene and
• Lead
The influent samples were collected from a sample port immediately following the
oil/water separator. The effluent samples were collected from a sample port located
on the injection line prior to the water re -circulation units. The influent and effluent
water samples were sent to ALS Analytical, Inc. (formerly a -Lab Analytical, Inc.)
of Houston, Texas (North Carolina Certification No. 624) for analysis of the site -
specific list by methods 8260 (VOCs) and 6020 (lead). Following receipt of the
laboratory analysis, the influent and effluent data were compared to calculate the
percent removal of the influent contaminants and compare the effluent results with
the respective NCAC 2L Section .0202(g) Class GA (2L) Standards. Table 1
presents a summary of the Zone 4 influent and effluent data as well as the
calculated percent removal for each month of operation in 2012.
As stated previously, an administrative permit modification request was made on 5
August 2009, to change the removal percentage specified in Section I.3 of Permit
No. WQ0029191 from 95% to 85% for TBA. The request was granted, and the
permit modified accordingly. During the 2012 operations of Zone 4, the average
removal efficiency for VOCs was 98.3% (without TBA) and the average removal
efficiency for TBA only was 9 1. 1%.
2.2.2 Summary of Annual Groundwater Sampling Event
The monitoring requirements of the non -discharge permit included annual sampling
of monitoring wells AMW-8S, AMW-9S, SBMW-2R, SBMW-2I, SBMW-2D and
SBMW-213 (see locations shown on Figure 1). Groundwater samples from these
wells were collected in November 2012 and sent to ALS for analysis of site -specific
VOCs and lead utilizing the methods indicated above. The results of this sampling
event were presented to the NCDWQ in a letter report entitled Submittal of Report
for Annual Monitoring Well Samples — November 2012, dated 31 December 2012.
As noted in this letter report, data collected from wells SBMW-213 and SBMW-2D
were inconsistent with historical data and determined to be anomalous. Further
investigation determined that the analytical data for wells SBMW-213 and SBMW-
2D were inadvertently switched by the laboratory. Table 2 presents a summary of
the results of the corrected November 2012 annual groundwater sampling event
results.
The results of the analysis indicated several detections of site constituents of
concern above their respective 21, Standard for groundwater. However, as noted in
Table 2, the majority of these contaminants were detected previously at
concentrations above the respective 2L Standard and the majority of the samples
exhibited stable or decreasing concentrations of site -specific VOCs in comparison
to the baseline sampling data (September 2004).
GES — June 2013-Revision 1 5 RETIA (Former TOTAL SITE # 1760)

The November 2012 data from the shallow water table wells (AMW-8S, AMW-9S,
and SBMW-2R) exhibited similar constituent detections compared to the previous
events. Monitoring well AMW-8S exceeded the Interim Maximum Allowable
Concentration (IMAC) for TBA and the NCAC 21, Standard for 1,2-dichloroethane,
while AMW-9S exceeded the 2L standard for benzene. Overall the concentrations
of detected constituents increased from the 2011 sampling event, but still remain
well below the baseline data (2004). The constituents and concentrations observed
in SBMW-2R were consistent with previous sampling events, except for benzene,
which was not detected during the November 2012 event. It should be noted that
the source area remedial technology (ET-DSPTM) targeted the vadose zone and
upper portion of the saturated zone (upper 35 to 45 feet). The absence of benzene
confirms that in -situ heating has removed the lightest and most volatile petroleum
hydrocarbons in this area, which readily transfer from the dissolved to the gaseous
phase.
The remaining three (3) wells (SBMW-2I, SBMW-2D, and SBMW-2B) are
screened in deeper portions of the saprolite and upper bedrock. The deeper portions
of the aquifer were not directly affected by the ET-DSPTM process. The
concentrations of site -related constituents in these wells remained consistent with
the previous data. As noted above, the source area treatment focuses on the upper
portion of the saprolite aquifer; therefore, these data are not expected to change as a
direct result of the source zone remedial efforts. The fact that the concentrations
have remained stable over time is an indication that the source strength has been
diminished.
2.2.3 Summary of Year End and Baseline Groundwater Monitoring
Baseline groundwater samples were collected from the Zone 4 extraction wells to
provide an initial assessment of the effectiveness of the selected source area
remediation technology. The baseline samples were collected the first week of
October 2010, prior to start-up of Zone 4 operations. The groundwater samples
were sent to ALS for analysis of the site -specific VOCs. Table 3 presents a
summary of these results along with data from mid -operation samples collected
throughout 2011 and 2012.
The baseline sampling results indicate that benzene, toluene, ethylbenzene, and
xylene and total petroleum hydrocarbons -gasoline range organics (TPH-GRO)
impacts were greatest in the central portion and along the central northwestern
boundary of Zone 4. TBA concentrations exhibited the greatest concentrations in
the south central portion of Zone 4 and minimal impacts around the perimeter. An
increase in VOCs is expected as part of the ET-DSPTM remediation process.
The application of heat to the subsurface mobilizes NAPL from the soil matrix via a
number of processes including increases in vapor pressure, decrease in LNAPL
viscosity and increases in solubility. Upon initial heating, concentrations of most
VOC's in groundwater will increase in the zone being heated until the temperature
of the water reaches the eutectic point of the azeotrophic mixture. As temperatures
increase beyond this point, concentrations in groundwater will decline.
GES — June 2013-Revision 1 6 RETIA (Former TOTAL SITE # 1760)

Throughout the Zone 4 operation, constituent concentrations were observed to vary
by initially increasing, then decreasing as the groundwater was continually treated
through heating, extraction and re -injection. Given that in situ thermal remediation
addresses multiple phases, the removal of contaminants by heating is a more
complete process than is possible with other techniques.
A comparison of the data for these events indicated that all Zone 4 wells exhibited
substantial decreases in total site -specific concentrations of benzene, toluene,
ethylbenzene, total xylenes (BTEX), and VOC concentrations and volumetric
extents across the zone. Figure 6 provides a baseline isoconcentration map.
Figure 7A provides the BTEX and VOC concentrations from the final
comprehensive sampling event in March 2012 while Figure 7B provides the year-
end total BTEX and VOC isoconcentration maps, in which a subset of the Zone 4
wells were sampled in July and August 2012.
To demonstrate the subsurface temperature increases through operations,
temperature contours from the McMillan -McGee website are included herein.
Attachment A presents the baseline subsurface temperature distribution maps for
Zone 4 at 7.5 and 19.5 ft bgs, respectively. The temperature distribution maps for
these intervals for the year-end (31 December 2012) are included as Attachment B.
