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 P:\PROJ\18895\18895.014\0&MSOl.doc 1-1 I I I I I I I I I I I I I I I I I I I 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.

Tennessee I I I I I I I I I I I I I I I I I I I 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. P: \PRO]\ 18895\ 18895.01 ◄ \O&MSOt.doc 1-3 I I I I I I I I I I I I I I I I I I I 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. P:\PROJ\1K895\18895.014\~1.doc 1-4 I I I I I I I I I I I I I I ,I I I I I 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. 1.4 ORGANIZATION OF O&M MANUAL This O&M manual has been organized into two volumes containing the seven sections and five appendices The organization is as follows: Volume I • Section 1.0 -Introduction • Section 2.0 -System Description and Process Flow P:\rROJ\18895\18895.014\0&MSOt.doc 1-5 Responsibility Site Holder System Owner System Manager System Monitoring · System Maintenance Process and Effluent Sampling Waste Disposal USEP A Remedial Manager NCDENR Remedial Manager P:\PROJ\l 8895\ 18895. 014\T0 IO I .DOC Table 1-1.

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. \ \BOJSH03\PROJECTS\PROJ\18895\18895.0H\0&.MS02doc 2-1 I 'I 1.- I I I I i I I I I 1· I I, I I I I 1,·, '~.' - 9 - 3 - 7 - 6 - 5 - 4 - 3 - 2 - § ! ~ ~ . . .

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. \ \BCNSHOJ\PROJECTS\PROJ\18895\ 18895.014\0&MS02.doc 2-2 I I I I I I I I I I I I I I I I I I I 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 \ \BCNSH03\FROJECTS\FROJ\18895\18895.0!4\0&MS03.doc 3-1 • D Table 3-1.

The air compressor and electrically actuated solenoid valves at the sparging points are interlocked with the blower so that if the blower is not running, the arr compressor will not run, and the solenoid valves will be automatically closed. • Flow element FE0202 is located on the air bleed-in line before the blower. This element displays the flow rate in cfm through this portion of the system and transmits signals to the PLC to display and record flow via the SCAD A system. • Pressure element PE0201 is located on the common suction header before the moisture separator. This element displays pressure as in.W.C. through this portion of the system and transmits signals to the PLC to display and record pressure via the SCADA system. • Temperature element TE0201 on the common suction header before the moisture separator sends a signal to the PLC to display and record temperature via the SCADA system. • Flow element FE0201 on the common suction header before the moisture separator displays flow rate in cfm through this portion of the system and transmits signals to the PLC to display and record flow via the SCADA system. The PLC calculates and displays the standard flow rate in scfm (FI8201) using the actual pitot tube differential pressure, temperature, and pressure inputs (FE0201, TE0201, and PE0201). • Level control element LE0201 indicates the condensate level in the moisture separator. The level control system consists of a level transmitter (L 1) and a level switch (LS). The level indication system has high water level and high-high water level set points. The high water level (HWL) set point activates an alarm (AL0201) which in turn activates an alarm light on the CPlO00 panel and activates the \ \BCNSH0J\PROJECTS\PROJ\ 18895\ 18895.014\Cl&MSOJ.doc 3-2 I D D I I I I I I I I I I I I I I I I autodialer notifying the operator that the moisture separator needs to be drained. 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. • Temperature element (fE0203) is located on the suction line after the suction header and bleed-in line. This element transmits a signal to the PLC to display and record the temperature via the SCADA system. • Flow element FE0203 is located on the suction line after the particulate filter and before the blowers.

An out-of-range temperature activates an alarm (TAH0204) on the SCADA system. • Pressure element PE0204 is located on the blower discharge pipe and transmits a signal to a locally mounted pressure indicator. This indicator displays pressure in in.W.C. through this portion of the system and transmits signals to the PLC to display and record the pressure via the SCADA system. • Two direct reading differential pressure elements, PE0205 and PE0206, are located on the GAC vessels down stream from the blowers to monitor pressure drops across each of the vessels. Pressure indicators display the pressure differential in in.W.C. and transmit signals to the PLC to display and record the differential via the SCADA system. The operator can monitor and set differential set points through the SCADA system. An out-of-range pressure differential activates an alarm (PDAH0205 and PDAH0206) which in turn activates an alarm light on CPl000 and activates the autodialer, notifying the operator. • Temperature element TE0205 is located between the GAC vessels and transmits a signal to the PLC to display and record the temperature via the SCADA system. An out-of-range temperature activates an alarm (TAH0205) on the SCADA system. • Temperature element TE0207 is located on the GA C effluent header downstream from the GAC vessels. This element transmits a signal to the PLC to display and record the temperature via the SCADA system. \ \BCNSHOJ \PROJECTS\PROJ\ 18895\ 18 S95.014 \O&MSOJ.doc 3-4 I I I m I I I I I I I • I I I I I I I • Pressure element PE0207 is located on the GAC effluent header downstream from the GA C vessels.

This element displays the pitot tube differential pressure in in.W.C. through this portion of system and transmit a signal to the PLC. The PLC displays and records the flow rate via the SCADA system by calculating and displaying the standard flow rate in scfm (FI8207) using the actual pitot tube differential pressure, temperature, and pressure inputs (FE0207, TE0207, and PE0207). An out-of-range flow activates an alarm on the SCADA system and the autodialer and deactivates the blowers. • Temperature element TE0901 located in the equipment area is used to monitor the ambient air temperature in that area. It transmits a signal to the PLC to display and record the temperature via the SCADA system. • Pressure element PE0901 is located in the equipment area and is used to monitor the ambient barometric pressure in the area. It transmits a signal to the PLC for use in standard flow rate calculations. • The extraction header from each extraction well (EW-1 through EW-10) has a pressure element for monitoring each extraction well vacuum. Each pressure element (PE0101 through PEOllO respectively) has a local pressure indicator display and sends a signal to the PLC. The operator can monitor the extraction well vacuum readings using the SCADA system. • The extraction header from each extraction well (EW-1 through EW-10) has a temperature element (TE0101 through TEOllO respectively) for \ \BCNSH0J\PROJECTS\PROJ\18895\ 18895.014\0&MSOJ.doc 3-5 I I I I I I I I I I I I I I I I I I I morutonng temperature. They transmit signals to the PLC to display and record the temperature via the SCADA system. • The extraction header from each extraction well (EW-1 through EW-10) has a flow element (FE0l0l through FE0ll0 respectively) for monitoring SVE system performance. They transmit signals to the PLC to display and record the flow rate via the SCADA system. The PLC calculates the standard flow rate in scfm (FI8101 through FI8110) using the actual picot tube differential pressure, temperature, and pressure inputs (FE0101, TE0101, and PE0l0l through FE0llO, TE0ll0, and PE0ll0 respectively). • Gas analyzers AE0201 and AE0202 are located at the blower inlet pipe and between the GAC vessels, respectively. The analyzers transmit signals to the PLC to display and record the PCE concentration via 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 \ \BCNSH0J\PROJECTS\PROJ\ !8895\18895.014\0&MSOJ.doc 3-6 m 0 B I I I I I I I I I I I I I I I I points (P A0301) define the operating range of the packaged air sparging system. 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).

The system can archive all the process data at a user-defined sampling frequency. A sampling frequency of 1 minute was used for the initial programming of the PLC data collection. • The operator can input laboratory analytical data into the PLC database. • The PLC has the ability to generate and print data summary reports. The content and format of the reports are easily programmable. Reports can be generated on demand that include the following information: \ \B01SH03 \PRO] ECT'S\PROJ\ 18 895\ 1S895.014 \O&M:503.doc 3-8 D I D 0 I I I I I I I I ·1 I I I I I I • Cwnulative effluent flow volwne measured in 1000 standard cubic feet (kscQ on daily, weekly, monthly, and yearly (to date) basis. • Average effluent flow rate (kscQ on a daily, weekly, monthly, and yearly (to date) basis. • The PLC continuously generates an alarm report that identifies the alarm, its time of activation, and the time at which it was acknowledged. \ \BCNSHOJ \PROJECTS\FROJ\ 18895\ 18895.014\0&MSOJ.doc 3-9 I I I g D I I I I I I I I I I I I I I 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 \ \BCNSH03\pROJECfS\pROJ\!8895\!8895.0!4\0&MSO<Joc 4-1 I I I I 0 I I I I I I I I I I I I I I 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 \ \BCNSHOJ\PROJECTS\PROJ\18895\ t8895.014\0&MS04.doc 4-2 I I I I u D B • I I I I I I I I I I I 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. \ \BQ\l"SHOJ \PROJECfS\PROJ\ 18895\ 18895.014 \O&M.504.doc 4-3 I I I I I u D u I I I I I I I I I I I 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.) \ \BG!SH03\PROJECTS\PROJ\18895\ 18895.014\0&MSOS.doc 5-1 I I Table 5-1.

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. \ \BGJSH03\PROJECI'S\PROJ\ 18895\18895.014\0&MSOb.doc 6-3 I I ,, I I I I I. m I O· I I I I I I I' I 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.
