1.0 INTRODUCTION
The United States Environmental Protection Agency (USEPA), United States Department
of Justice, Beaunit Corporation, Burlington Industries, Inc., and El Paso Natural Gas d/b/ a
El Paso Energy Corporation (El Paso) have entered into an agreement (Consent Decree) for
the performance of response work at the FCX-Statesville Superfund Site (Site) Operable
Unit 3 (OU3) in Statesville, North Carolina consistent with the National Contingency Plan.
lbis response work includes performance of a Remedial Action (RA) for soil and
groundwater at the Site.
The RA is being performed by El Paso to implement the response actions selected for the
Site. The RA Work Plan Quly 2000) provided a plan of action for completing the RA
activities and presented a discussion of the tasks to be performed, a Project Delivery
Strategy, a Construction Management Plan, and a Construction Quality Assurance Plan
(CQAP). The RA Work Plan addressed the technical requirements of the September 30,
1996 Record of Decision (ROD) issued by the USEPA and incorporated work elements and
deliverables previously specified in the Consent Decree, Statement of Work, and in the
approved Remedial Design (RD) Work Plan.
The RA for the treatment of groundwater and soil contamination at the Site is an arr
sparging/ soil vapor extraction (AS/SVE) system with monitored natural attenuation for
areas down gradient of the AS/SVE system. An observational approach has been
incorporated into the RD and RA for implementation of the AS/SVE system due to the
heterogeneity of the soil at the Site as identified during the Pre-Design Investigation. The
observational approach calls for a Phase I AS/SVE design, construction, and testing and
allows for a Phase II design, construction, and operation at a later time if determined
appropriate. The construction of the Phase I AS/SVE system has been completed and is
documented in the report entitled "Construction Completion Report for the Phase I Air
Sparging and Soil Vapor Extraction System, FCX-Statesville Superfund Site OU3, Statesville,
North Carolina" dated November 2000 by Brown and Caldwell (hereafter referred to as the
Construction Completion Report). If the Phase I AS/SVE system is found to be adequate

without modification, the system will be operated to address the groundwater and soil
contamination in the source area without the need to implement Phase II.
1bis Operations and Maintenance (O&M) Manual presents the procedures and information
for operating and maintaining the Phase I AS/SVE system.
1.1 BACKGROUND INFORMATION
The following includes a brief description of the Site as well as Site conditions.
1.1.1 Site Location and Description
The OU3 Site is located in Iredell County approximately 1.5 miles west of downtown
Statesville, North Carolina (see Figure 1-1). The Site consists of the soil, groundwater,
sediment, and surface water contamination emanating from the textile plant property
currently owned by Burlington. The property is approximately 15 acres in size. Two large
buildings consisting of a warehouse (approximately 60,000 square feet in size) and a textile
plant building (approximately 275,000 square feet in size) are located on the Burlington
property (see Figure 1-2).
Land immediately surrounding the Site is predominantly industrial with a variety of other
uses ranging from commercial to 'residential with associated school and church facilities.
Farther from the Site, rural land in the Statesville area is used for timber farming, grain crops
farming, and dairy farming.
The Site lies within the geologic belt known as the Blue Ridge-Inner Piedmont Belt, which is
situated in the Inner Piedmont Physiographic Province in western-central North Carolina.
1bis province is characterized as gently rolling slopes. The Blue Ridge-Inner Piedmont Belt
consists of metamorphic rocks including gneisses and schists. These rocks have weathered
to form a relatively thin overburden of saprolite, which is observed throughout the Site.

Groundwater at the Site is observed within the saprolite and underlying bedrock. Saprolite
forms the uppermost hydrogeologic unit. Groundwater occurs within the pore spaces of the
saprolite under water table conditions. Groundwater within the fractured bedrock unit
occurs under unconfined or semi-confined conditions. Site information indicates that the
two units are in hydraulic communication. Groundwater gradients observed on-Site indicate
that groundwater in the saprolite and bedrock appears to be flowing both to the north and
to the south from the textile plant.
1.1.2 Site Conditions
Several media and constituents of interest are associated with OU3. The pnmary
constituents of interest present within OU3 include perchloroethylene (PCE), also called
tetrachloroethene, and other chlorinated hydrocarbons. The groundwater contains primarily
PCE and other volatile organic compounds (VOCs). On-Site soil contains primarily VOCs
and to a lesser extent, inorganics and polynuclear aromatic hydrocarbons (P AHs).
Groundwater and soil contamination are being remediated by AS/SVE with monitored
natural attenuation for areas down gradient of the AS/SVE system. Surface water and
sediment associated with an intermittent stream originating from a seep to the north of the
Burlington textile plant also contain some inorganic constituents, polychlorinated biphenyls
(PCBs), and VOCs; however, it was determined that the constituent concentrations posed
no risk and no remediation is required.
1.2 DESCRIPTION OF AIR SPARGING/SOIL VAPOR EXTRACTION SYSTEM
The AS/SVE process that was installed during the Phase I construction consists of
the following components:
• twenty-five triple-purpose wells
• SVE system
• air sparging system
• Supervisory Control and Data Acquisition System (SCAD A) system_
• security measures.

While each of the triple-purpose wells has a specific function now, the wells were designed
and constructed so that any of them can be used for SVE, air sparging, monitoring, or any
combination of the three. The above-ground piping and instrumentation have been installed
so that the wells can be used as follows:
• two wells for both air sparging and SVE
• eight wells for SVE
• fifteen wells for monitoring probes.
The SVE system consists of the SVE wells, SVE header piping, a packaged blower system, a
heat exchanger, and two granular activated carbon (GAC) vessels. The piping includes a
6-inch diameter common extraction header and 2-inch diameter connecting pipe branches to
the SVE wells. The SVE header and branch piping are fabricated from high-density
polyethylene (HDPE). The SVE blower system is skid-mounted and includes a liquid
separator, a particulate filter, an inlet filter and silencer for bypass air, and two blowers piped
to operate individually or in parallel. The blowers operate to draw the soil gas out of the
selected SVE wells, through the heat exchanger, and through two GAC vessels that are
operated in series to capture organic vapors before the exhaust gas is discharged to the
atmosphere. The heat exchanger reduces the vapor temperature to about 90°F or less,
which improves the GAC absorptive capacity for the Site volatile organic compounds
(VOCs). The GAC in the vessels can be exchanged when the carbon in one vessel reaches
its adsorptive capacity. The treated air is checked by an in-line gas analyzer and subsequently
exits the carbon vessels and the building through a 6-inch vent pipe that extends above the
roof.
The air sparging system consists of an oil-free air compressor. The air sparging piping
consists of 1-inch HOPE, which is rated for compressed air. The piping runs from the air
compressor to the two air sparging wells. The system forces air into groundwater through
the screened section of the air sparging wells. Solenoid valves located in the air piping to
each of the air sparging wells allow for the sparged air to be injected in pulses at desired
frequencies and durations.

The SCADA system consists of instrumentation connected to the process piping and
equipment. These instruments provide necessary operation data to a programmable logic
controller (PLC). The controls for the system are housed in two cabinets located in the
same area as the equipment. One cabinet houses the motor starters, PLC, hand switches,
alarm lights and other process electrical components. The other houses a computer that
enables an operator to monitor and control the AS/SVE process. Data acquisition and
system operation can also be accomplished from a remote computer via a modem.
The AS/SVE process equipment and control cabinets are located within an equipment area,
which is secured inside an eight-foot tall chain-link fence with locking gates. The equipment
area is accessible from the outside of the textile plant using a key-operated, overhead coiling
door. The AS/SVE wells and piping are protected by bollards that are set into the concrete
floor or asphalt pavement.
The City of Statesville provides electric service to the AS/SVE system that is independent of
the building's main power. BellSouth provides telephone service using a telephone line from
a terminal outside the building to allow remote access to the SCAD A system via modem.
1.3 RESPONSIBILITIES AND CONTACTS
A list of the responsibilities and contacts for the AS/SVE system is presented in Table 1-1.

2.0 SYSTEM DESCRIPTION AND PROCESS FLOW
The AS/SVE system described in this manual is used to remediate VOC-contaminated
groundwater and soil at the FCX-Statesville Superfund Site OU3. Figure 2-1 shows a plan
view of the site with locations of the piping, equipment, wells, and monitoring probes.
Figures 2-2 and 2-3 present a piping and instrumentation diagram for the AS/SVE system.
Appendix A presents full-size record drawings of the piping and equipment layout and the
piping and instrumentation diagram.
The SVE blower package draws the vapors from the SVE wells; which are screened in the
vadose zone, using Ametek Rotron regenerative blowers. The two blowers can be operated
together or one at a time depending on the achievable vapor flow rate from the SVE wells.
The SVE package also includes a moisture separator tank, a particulate filter, silencers on the
discharge of each blower, and a silencer on the bleed-in line. The SVE package pulls vapors
from the extraction wells through the blowers and discharges into the GAC vessels. A heat
exchanger cools the vapor as it passes from the blowers into the GAC vessels.
During air sparging, an air compressor supplies air to the groundwater under the site at the
two sparging well locations. The air is carried through a 1-inch I-IDPE pipe to the well
casings and disperses into the groundwater. The compressor is an oil-free, tank-mounted
model manufactured by Gardner-Denver. The air pressure is controlled by a pressure
regulator located on the discharge line from the compressor and by control valves located on
the air line at each sparging well. Electrically activated solenoid valves are also located on
the air line at each sparging well and allow the air to be injected in pulses that are controlled
by a timing function in the SCAD A system.
There are two GAC vessels, each containing 2000 pounds of carbon. A piping manifold,
mounted adjacent to the GAC vessels, allows for series flow, parallel flow, or independent
flow through the GAC vessels by manually changing the valve positions. The primary mode
of operation is series flow through both GAC vessels.

When the primary or lead GAC vessel in the series requires a carbon change-out, it can be
manually isolated with the valving while the secondary GAC vessel stays on-line to treat
mcorrung vapors. The valving is adjusted after change-out has occurred so that the
secondary GAC vessel becomes the primary GAC vessel in the series and the changed-out
GAC vessel becomes the secondary vessel. This rotation is repeated as the GAC is spent in
each vessel. There is no requirement for moving vessels or disconnecting piping to rotate
primary and secondary positions in the series.
When the clean air passes out of the GAC vessels, it is vented above the roof of the
building.
The operation of AS/SVE is controlled using a SCADA system, which enables the operator
to control the process operations locally from a desktop computer or remotely via a modem ..
The SCADA system consists of the following equipment: a programmable logic controller
(PLC), desktop computers (on-Site and remote), an alarm printer, a report printer, and an
auto-dialer. The PLC receives process information from the instrumentation that is located
throughout the AS/SVE system. The process information can be monitored and controlled
from the local desktop computer or from a remote computer. The SCADA system alerts
the operator in the event of selected alarm conditions with a local panel alarm and an auto-
dial for remote notification of the alarm condition.

3.0 RJNCTIONAL DESCRIPTION OF AS/SVE SYSTEM
This section presents a functional description of the AS/SVE system. A listing of the
instrument tag identification numbers that are utilized by the SCAD A system are provided in
Table 3-1 for reference. The following sections describe the functions of the major
equipment comprising the system as well as the instrumentation that allows the operator to
control and monitor the system.
3.1 SOIL VAPOR EXTRACTION (SVE) SYSTEM OPERATION
The SVE system extracts soil vapor from the SVE wells. The two SVE blowers can be
activated and deactivated using three position hand/ on/ auto (HOA) switches mounted on
the CPlOO0 panel. The blower run indicator lights are located on the CPlO00 panel. The
HOA switches allciw the operator to manually tum the blowers on and off or to allow them
to operate in the automatic mode controlled by PLC. In the automatic mode, the blowers
will shut off when the high-high liquid level alarm on the moisture separator is activated and
when the blower discharge pressure is out of normal range. The operator can select the
blower operating mode (on/off/ auto) and monitor the blower status (off/on) from the
SCADA system (MS0201 and MS0202). The SCADA system records the blower process
data and alarm history as information is received from the following instruments:
• Pressure element PE0203 monitors the vacuum on the suction side of the blower.
The PLC is programmed to have a low and high pressure set point. The low-
pressure (LP) set point deactivates the blowers and activates an alarm (P A0203)
which in tum activates an alarm light on the CPlOO0 panel and activates the
autodialer notifying the operator that the blower is not running properly. A high-
pressure (HP) set point deactivates the blowers and activates an alarm (P A0203)
which in tum activates an alarm light on the CPl000 panel and activates the
autodialer notifying the operator that the blower is not running properly. After
either an LP or HP alarm, reactivation of the blower requires an operator
command through the SCADA system. The pressure output is displayed on the
SCADA system in inches of water column (in.W.C.) vacuum. The operator can

The high-high water level (HHWL) set point activates an alarm (AL0202) which in
turn activates an alarm light on the CPl000 panel, activates an autodialer, and
deactivates the AS/SVE system. Once the water level in the moisture separator
falls below HHWL deadband, reactivation of the air sparging and SVE systems
requires an operator command through the SCADA system.
• Differential pressure indicator PE0202 located on the particulate filter before the
blower indicates the pressure drop across the filter. It displays the pressure
differential in in.W.C. and transmits signals to the PLC to display and record the
pressure differential via the SCADA system. A high-pressure differential activates
an alarm (P AH0202) located on the SCADA system and the autodialer to notify
the operator of the high-pressure differential. The operator can change the alarm
set point through the SCADA system.

3.2 AIR SP ARGING SYSTEM OPERA TIO NS
The packaged air sparging system will supply air to sparging wells SW-1 and SW-2. The
compressor's run indicator light and hand/ off/ auto (HOA) switch are located on the
instrument control panel (identified as CPl000). The HOA switch allows the operator to
manually tum the compressor on and off or operate it in the automatic mode where it is
controlled by the PLC. The compressor is electrically interlocked with the extraction
blowers so that the compressor can not operate unless at least one of the extraction blowers
is also operating. The operator is able to select the compressor operating mode
(on/off/auto) and monitor compressor status (off/on) from the SCADA system. The
SCADA system records the compressor process data and alarm history as information is
received from the following instruments:
• Pressure element PE0301 monitors the discharge pressure at the compressor. The
compressor is deactivated by both a LP set point and a HP set point. The two set

The output from the element is displayed on the SCADA system in pounds per
square inch (psi). The operator can monitor the pressure readings, monitor set
points, and change set points through the SCADA system.
• The influent air line to each sparging well has a solenoid valve for pulsing airflow
to the two sparging wells. Each solenoid valve is controlled by the PLC (1M0401
and TM0402). The airflow to each well can be pulsed on and off independently by
an adjustable timed function that is controlled by the PLC. The operator can
monitor the valve status (open/closed) and set the pulse cycle as well as monitor
and change set points from the SCADA system. The PLC will automatically close
the valves whenever the SVE system is not operating.
• The influent air line to each sparging well has a pressure element for monitoring
spargmg pressure. Each pressure element (PE0401 and PE0402) has a local
pressure indicator (PI) display and sends a signal to the PLC. The operator can
also monitor sparging well pressure readings from the SCAD A system.
• A temperature element (TE0401 and TE0402) is provided on the influent
air line to each sparging well for monitoring sparging air temperature. The
output is transmitted to the PLC to display the instantaneous temperature
via the SCADA system.
• A flow element (FE0401 and FE0402) is provided on the influent air line
to each sparging well for monitoring the actual flow rate in cubic feet per
minute (cfm). The instrument will transmit signals to the PLC to display
both the instantaneous flow rate and the daily cumulative flow via the
SCADA system. The PLC calculates the flow in standard cubic feet per
minute (scfm) (FI8401 and FI8402) using actual pitot tube differential
pressure, temperature, and pressure inputs (FE0401, TE0401, PE0401,
and FE0402, TE0402, PE0402 respectively).

4.0 OPERATION OF SYSTEM CONTROLS
The controls of the AS/SVE system equipment reside in two control cabinets, CPl 000 and
the computer cabinet. The system can either be controlled locally from these two cabinets
or from a remote computer. There is a main electrical disconnect for the AS/SVE system
where the electrical service enters the building. The following sections provide details about
the components and operations of the aforementioned controls. Detailed documentation on
the instrumentation and controls is provided in Appendix E.
4.1 MAIN ELECTRICAL DISCONNECT PANEL
The main electrical disconnect panel is located in the northwest comer of the equipment
area. Electricity for the system comes into the building to the main electrical disconnect
where it is then routed to the control cabinets. The main disconnect breaker can be used to
shutoff all of the electrical power to the system. The main electrical disconnect panel also
contains breakers for equipment secondary to the AS/SVE system including the overhead
.. , coiling door, the overhead lights, and the 110 VAC utility outlets.
4.2 CONTROL PANEL CP1000
Control panel CPlO00 houses the vital control components for the AS/SVE system. These
components include the PLC, the motor starters, the instrumentation termination blocks,
and the uninterruptable power supply (UPS). The control panel is equipped with a small
heater in order to protect the components from condensation at low temperatures. The
signals from the instrumentation .throughout the AS/SVE process are received by the PLC;
the PLC controls the process equipment by switching on or off the equipment as described
in Section 3 .0. The PLC also communicates with the desktop computer, which provides the
operator interface.
The four motors in the AS/SVE system are controlled by motor starters, each of which has
an HOA switch on CP1000. The HOA switches are three-way selector switches that allow

for manual or automatic operation of the two blowers, heat exchanger fan, and air
compressor.
• The "Hand" position manually energizes the respective piece of equipment. The
"Hand" position bypasses the automatic PLC function. When operating
equipment in the "Hand" mode, close attention should be given to the system
conditions because the PLC would not have control of the system if an off-normal
or potentially dangerous condition were to occur.
• The "Off" position prevents the device operation.
• The "Automatic" position allows for the operation of the respective equipment by
the PLC. The equipment will start and stop automatically depending on the
information provided by the field instrumentation.
• A green status indicator light below each HOA switch illuminates when the
associated control circuit is energized.
Also located on the front door of CPlO00 are yellow alarm indicator lights and a light test
button. The button should be used periodically to test the bulbs in the alarm indicator
lights.
4.3 COMPUTER CABINET
The computer cabinet houses a desktop computer, a monitor, an alarm printer, a report
printer, and an autodialer. Additionally, the cabinet is equipped with a small air conditioner
and heater in order to maintain an internal temperature that will not damage the cabinet's
contents. The computer enables the operator to interface with the system controls and to
monitor the field conditions at various points in the system. In the automatic mode, the
operator uses the computer to start and stop the system. He or she can also use the
computer to generate cumulative reports using one of the cabinet's printers and the software

residing on the computer. For more information about these reports, consult Section 3.3 of
this manual.
Some of the components inside the computer cabinet relate to the emergency response
features of the SCADA system. The autodialer will alert the operator in the event of an
alarm condition by playing a computerized, alarm-specific voice message over the pre-
programmed phone number. Whenever an alarm condition is experienced, the system prints
the date, time, and alarm code on the alarm printer inside the computer cabinet.
4.4 REMOTE COMPUTER
The remote computer contains software that allows the operator to interface directly with
the SCADA system over a modem from any off-Site location. Using this remote computer,
the operator can monitor system status, start and stop the system, and download data and
reports.

5.0 OPERA TING PROCEDURES
This sect10n provides general procedures for the system startup and shutdown. The
procedure has provisions for startup and shutdown with the system while operating either in
the automatic mode or in the manual mode.
5.1 SYSTEM STARTIJP
The following subsections describe the steps in detail that the operator should follow to
startup the AS/SVE system.
5.1.1 Set Process Valve Positions for Startup
Valve positions for process flow should be set at each of the air sparging and SVE wells and
in the equipment area according to Table 5-1. Valve identification numbers and locations
are shown on Figures 2-2, 2-3, and 5-1. Set the valve positions as follows:
1. Open the ten SVE extraction well valves (EV-1 through EV-10).
2. Open air sparging system valve AV-1 at the air compressor and close the control
valves SV-1 and SV-2 at the air sparging wells (the control valves will be opened
after system startup to set the desired air sparging flow rates).
3. Partially open the blower air-bleed valve, CV-2, to position 5 as marked on the
valve handle. After system startup, adjust the valve position to obtain the desired
SVEvacuum.
4. For single blower operation, open the SVE blower system valves CV-1, CV-3,
CV-4, and CV-7. (Note: If two blower operation is desired, also open CV-5 and
CV-6.)

6.3 MAINTENANCE OF AS/SVE SYSTEM
System maintenance includes routine calibration of process instruments; change-out of the
GAC Vessels' media; repair of equipment, piping, valves, instruments, etc.; and process
modifications or upgrades. The maintenance personnel who perform work on the AS/SVE
system shall have the 40-hour HAZWOPER training because the system processes
hazardous vapors.
6.3.1 Routine Calibration of Instrumentation
Routine calibration of instrumentation will be performed at regular intervals. Instruments
giving suspect data will be recalibrated as necessary.
6.3.2 Particulate Filter Replacement
Located above the condensate collection tank on the blower package is the blower
particulate filter. There is a differential pressure display located at the filter housing. When a
pressure differential of 10 in.W.C. is reached, the filter should be replaced.
6.3.3 GAC Media Replacement
Since influent contaminant levels to the system may vary from day to day, it is difficult to
project the longevity of the GAC before it will become exhausted and will require a
change-out. When VOC are detected at concentrations of 5 ppm or greater by the gas
analyzer located between the two GAC vessels, then change-out of the spent carbon from
the primary GAC vessel shall be initiated. The secondary GAC vessel will act to adsorb and
remove those contaminants which breakthrough the primary vessel until the primary vessel
can be replenished with virgin carbon. Appendix B contains equipment specifications and
operating instructions, which are further discussed in Section 7.0.
The GAC system should be maintained so that the secondary GAC vessel's effluent quality
always remains below detectable limits for VOCs.

Spent carbon is vacuumed or removed from the respective vessel through the manways
provided, and transferred into drums for off-site disposal. The disposal of spent media will
be managed by the waste disposal contractor. Virgin GAC is then loaded into the vessel
through the same port. Upon completion of this procedure the secondary vessel in the
series shall assume the primary position while the newly loaded vessel takes the secondary
position. This rotation shall be repeated as GAC vessels are exhausted. Refer to the
corresponding valve arrangement specified in Table 5-1 for the rotation of vessels.
6.3.4 Other Maintenance
Other scheduled maintenance activities will be performed in accordance with the frequencies
provided in Table 6-1. All system inspection and maintenance activities should be recorded
on the form provided in Table 6-4,
