1.0 INTRODUCTION
The United States Environmental Protection Agency (USEPA), United States Department of
Justice (DOJ), Beaunit Corporation (Beaunit), Burlington Industries, Inc. (Burlington), 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 Superfund Site
(Site) Operable Unit 3 (OU3) in Statesville, North Carolina consistent with the National
Contingency Plan (NCP). This response work includes performance of a Remedial Action
(RA) for soil and groundwater at the Site.
The RA will be performed by El Paso to implement the response actions selected for the Site.
This RA Work Plan, which provides a plan of action for completing the RA activities,
presents a discussion of the tasks to be performed; a project delivery strategy; a construction
management plan; and a construction quality assurance plan. This Work Plan addresses the
technical requirements of the September 30, 1996 Record of Decision (ROD) issued by the
USEP A and incorporates work elements and deliverables previously specified in the Consent
Decree, Statement of Work (SOW), and in the approved Remedial Design (RD) Work Plan.
1. 1 REQUIREMENTS
According to the Consent Decree, El Paso and Burlington are required to transmit to the
USEPA and the North Carolina Department of Environment and Natural Resources
(NCDENR) a draft RA Work Plan within 60 days of the approval of the Final RD. The Pre-
Final RD Submittal was transmitted to the USEPA and the NCDENR on September 17,
1999. Approval of the Final RD was received on February 16, 2000 and the Final RD was
issued on March 29, 2000. This RA Work Plan provides the documentation necessary for
construction of the RA in accordance with the SOW, which is Appendix B of the Consent
Decree, and as required by the RD (Brown and Caldwell, 1999). Also required as part of RA

1.3 BACKGROUND INFORMATION
The following includes a brief description and history of the Site as well as Site conditions.
1.3.1 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 present 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.
This 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.
1.3.2 Site History
The textile plant was constructed at the OU3 Site in 1927. From 1955 to 1977, the textile
plant was operated by Beaunit Mills, later known as Beaunit Corporation (Beaunit). In 1967,
Beaunit became a subsidiary of El Paso. In April 1977, Beaunit sold substantially all of its
assets, including the plant, to Beaunit II, Inc. As a part of that transaction, Beaunit changed its
name to BEM Holding Corporation (BEM), and Beaunit II, Inc. changed its name to the
Beaunit Corporation. In July 1978, the Beaunit Corporation (formerly Beaunit II, Inc.) sold
the textile plant to B~aunit Fabrics Corporation (Beaunit Fabrics). In 1981, Burlington
purchased certain assets, including the textile plant, from Beaunit Fabrics. Burlington
presently owns the textile plant; the plant was closed in 1999, and Burlington is currently
offering the plant for sale.

1.3.3 Site Conditions
Several media and constituents of interest are associated with OU3. The primary constituents
of mterest 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). Surface
water and sediment associated with an intermittent stream originating from the 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.
1.4 DESCRIPTION OF THE SELECTED REMEDY
The RA involves air sparging and soil vapor extraction in the source area of groundwater
contamination and monitored natural attenuation of the downgradient portions of the plume.
A phased approach will be utilized to implement the RA. Phase I of the Remedy consists of
the following major components:
• two air sparge wells
• ten soil vapor extraction wells
• fourteen monitoring probes
• air sparging and soil vapor extraction package systems
• off-gas treatment
• Supervisory Control and Data Acquisition (SCAD A) system
• monitored natural attenuation.
A more detailed description of the overall system is provided in the RD submittal.

1.4.1 Soil and Groundwater Objectives
Elevated levels of several constituents, primarily VOCs, are present in the soil of OU3. No
cleanup levels have been established for on-Site impacted soil; however, the objective of the
RA for soil is to minimize the potential for vapor transport and infiltration of VOCs from the
soil into the groundwater using SVE technology.
Groundwater containing VOCs has been identified in the shallow saprolite and intermediate
bedrock aquifers. Air sparging was selected in the ROD to treat groundwater constituents of
concern by removing VOC mass and controlling migration in order to meet Federal
Maximum Contaminant Levels (MCLs) or the North Carolina Groundwater Standards,
whichever are more protective. These will be referred to as the Performance Standards and
are listed in Section VIII of the ROD. The objective of the RA for groundwater is to
implement an air sparging remediation for impacted groundwater.
Sampling and analysis of the groundwater will be performed to monitor the OU3 RA
performance and to monitor the extent and effectiveness of natural attenuation. Additionally,
steps will be taken to check that the groundwater in the affected area continues to be unused.
A City of Statesville ordinance requires each lot to have a separate water connection if water
mains are available. Water mains are available in the area affected by OU3. In circumstances
where city supplied water is unavailable, authorization to drill a well must be obtained from
the county health department. North Carolina well construction standards require that
drillers obtain construction permits prior to well installation. A well survey performed
during the RI/FS found that no wells had been installed in the area affected by OU3. The
area was in compliance with the city ordinance. Routine checks, similar to the well survey
performed during the RI/FS, will be made as part of the RA for the purpose of finding new
wells that may have been constructed in the O U3 affected area. On a semiannual basis, the
Iredell county health department and the Mooresville Regional Office of the NCDENR will
be contacted to check that no well construction permits have been requested in the area
affected by OU3. At the time of each groundwater sampling event, the OU3 affected area will

be visually inspected for evidence of new well construction by a hydrogeologist driving
through the OU3 affected area on public roads. These steps should provide a sufficient check
against the installation of new wells in the area affected by O U3.
1.4.2 Air Sparging with Soil Vapor Extraction
Air sparging with soil vapor extraction (AS/SVE) will be used to address the source area of
contamination. Air sparging introduces air into groundwater to remove voes. This is
accomplished through injection of air under pressure through small-diameter wells that are
screened within or below the contaminated interval at or near the base of the aquifer. The
voes are stripped from the aqueous phase into the gas phase. Once the voes reach the
vadose zone, they are typically removed by SVE.
The RA will consist of two sparge wells (SW-1 and SW-2) as shown in the RD. Each sparge
well will be installed in the same borehole with an extraction well (EW-1 and EW-2) by using
a concentric well design. The sparge air will be supplied by a commercially available packaged
air sparging system. The packaged air sparging system (e.g., compressor, etc.) will be installed
in the equipment area shown on the RD plans.
Soil vapor extraction uses the induced movement of air through the vadose zone to volatilize
and remove VOes. In the RA a vacuum source (i.e., blower) will be attached to a common
header connecting 10 extraction wells. Each SVE well will be screened across the impacted
interval of the vadose zone. The blower creates a partial vacuum (reduced pressure) within
the well and induces airflow from the surrounding soils towards the SVE well. As the air
moves through the impacted soils, the portion of the voes that is present in the vapor phase
flows towards the SVE well and is removed through the well along with the extracted air.
The voes associated with the soils and present as free phase liquids (either between the soil
particles or present as a layer on top of the groundwater) will gradually partition (volatilize)
into the surrounding soil gas and will be extracted with the recovered air. The vacuum will be
provided by a commercially available packaged soil vapor extraction system. The packaged

system (e.g., blower, moisture separator, etc.) will be installed in the equipment area shown on
the RD plans. An off-gas treatment system consisting of granular activated carbon canisters
will be installed following the packaged soil vapor extraction system. The granular activated
carbon will remove VOCs from the extracted air prior to discharge to the atmosphere.
A network of fourteen momtonng probes will also be installed in order to momtor the
effectiveness of the air sparging and soil vapor extraction installation.
1.4.3 Supervisory Control and Data Acquisition System
Each air sparge and soil vapor extract10n well will be equipped with instrumentation for
monitoring flow, temperature, and pressure. In addition, various instrumentation will be
installed on the mechanical equipment in the equipment area.
Each meter and/ or gauge will be both direct reading and transmitting. Each reading will be
transmitted to the on-site control system via signal wire. The on-site control system will
consist of a local panel with hand switches, and a programmable logic controller (PLC) for
automatic operation of the system. The PLC will be programmed as specified in the RD. The
on-site control system will be linked to a SCADA computer that will monitor and record the
system operation, as well as allow for remote operation of the system.
1.4.4 Monitored Natural Attenuation
Natural processes that reduce the mass and concentrations of the VOCs present in OU3 have
been observed in Site groundwater samples. For this reason, monitored natural attenuation is
being evaluated to determine the extent to which it may complement the active remediation
technologies of SVE and air sparging being implemented at the Site. Monitored natural
attenuation, also referred to as intrinsic remediation, relies on the natural restorative capacity
of aquifers to control migration and reduce the masses of constituents of concern. The
mechanisms that contribute to natural attenuation include adsorption, diffusion, dispersion,

volatilization, and degradation. Monitored natural attenuat10n will be used to treat the
portion of the plume not addressed by air sparging and soil vapor extraction.
Long term (semiannual) monitoring of Site contaminants and natural attenuation parameters
are required for monitored natural attenuation. The primary objective of long term
monitoring is to observe whether the natural attenuation processes along with any active
remediation are serving to reduce or control expansion of the plume.

2.0 REMEDIAL ACTION SCOPE OF WORK
This section describes the RA tasks to be performed and work products to be submitted and
provides a project management plan in accordance with the SOW.
2.1 WORK TASKS TO BE PERFORMED
Prior to approval of this RA Work Plan, several of the RA activities may commence. The
following major tasks may be performed for the RA prior to RA Work Plan Approval:
• Permit Preparation and Approval
• Procure RA Contractor
• Subcontractor Bid Solicitation
• Contract Award.
The following major tasks will be performed for the RA subsequent to RA Work Plan
approval:
• implementation of Phase I
• performance of Final Construction Inspection and preparat10n of Final Phase I
Construction Report
• preparation of the O&M Manual
• preparation of the Phase I Performance Testing Plan
• implementation of Phase II (if required).
Each of these major tasks is discussed in more detail below.
Permit Preparation and Approval. Air Sparging and Soil Vapor Extraction within the Site
boundaries is considered an on-site action. Section 121(e)(l) of the Comprehensive
Environmental Response, Compensation, and Liability Act (CERCLA) exempts on-site

remedial activities from any federal, state or local permmmg reqmrements; however, the
USEP A encourages these remedial activities to achieve the substantive standards of applicable
federal, state, and local laws and regulations. Therefore, the air sparging and soil vapor
extraction system will be structured to meet the regulatory requirements identified in Section
4.4 of the RD.
Procure RA Contractor. El Paso has entered into an agreement with Brown and Caldwell to
be the RA Contractor for implementation of the Phase I construction at OU3. Brown and
Caldwell will in turn solicit subcontractors to perform installation of the wells, monitoring
probes, mechanical systems, electrical systems, and control systems.
Subcontractor Bid Solicitation. The RA Contractor will send requests-for-bid (RFBs) to the
candidate subcontractors that are identified as having qualifications to perform specific
portions of the work. The number of subcontractors will be adequate to provide competitive
pricing for the project, but not so many as to unnecessarily encumber the bid review process.
The subcontractors will be allowed to review the bid package, after which a Pre-Bid Meeting
will be conducted on Site. Subsequent to that meeting, the subcontractors will be required to
submit a bid. Each of the subcontractors will be made aware of the existence of the Consent
Decree and other potentially applicable background documents for assistance in preparing
their bids. The bids received will be reviewed for completeness, technical approach, and cost
among other criteria. At a minimum, the following subcontracts are anticipated:
• drilling subcontractor
• surveyor
• mechanical, electrical, and controls subcontractor.
Implementation of Phase I. The RA Contractor will conduct a Pre-Construction Meeting at
the site after contract award. This meeting is required by the Consent Decree. Following the
Pre-Construction Meeting, the RA Contractor will mobilize to the Site. Subsequent to
mobilization, the AS/SVE system will be installed in accordance with the approved Final

Design plans and specifications. In general, installation will include installation of the
AS/SVE wells and monitoring probes, placement of the header piping and electrical conduit
from the extraction wells to the equipment area, and installation of the required mechanical
equipment, instrumentation, and controls. Once installation is complete, system operational
testing will be performed.
Performance of Final Construction Inspection and Preparation of Final Phase I
Construction Report. As specified in the Consent Decree, a Final Construction Inspection
will be conducted prior to demobilization from the Site. The inspection will consist of a
walk-through of the entire Site with the objective of determining whether the Phase I
construction is complete and consistent with the Consent Decree. All equipment will be
operational and will have been tested prior to the inspection. As necessary, the inspection will
result in a list of outstanding items to be addressed by the RA Contractor before
demobilization. Once those items are completed to the satisfaction of El Paso and the
USEP A, a Final Phase I Construction Report will be prepared as described in Section 2.2 of
this RA Work Plan.
Preparation of the O&M Manual. After submittal of the Final Phase I Construction
Report, the existing O&M Plan will be revised to reflect the actual equipment installed at the
Site for the RA. The new O&M Manual will be used by El Paso to properly operate and
maintain the system. The O&M Manual will be prepared as discussed in Section 2.2 of this
Work Plan.
Preparation of the Phase I Performance Testing Plan. The Phase I Performance Testing
Plan will be submitted with the Phase I Construction Report. The Phase I Performance
Testing Plan will be used to evaluate the effectiveness of the Phase I installation and the need
(if any) for a Ph~se II installation. The Phase I Performance Testing Plan will be prepared as
discussed in Section 2.2 of this RA Work Plan.

3.0 OPERATION AND MAINTENANCE PLAN
The purpose of this O&M Plan is to provide the operator with a description of procedures for
operation and maintenance of the AS/SVE system for OU3 installed at the FCX Superfund
Site.
This Plan has been prepared as part of the RA Work Plan submittal. Once the AS/SVE
system has been installed, the O&M Plan will be revised as an O&M Manual to include
detailed operating procedures and equipment information based on actual equipment installed
and observations made during the initial operation of the AS/SVE system. The draft O&M
Manual will be prepared at or near completion of construction activities. It is probable,
however, that some aspects of the O&M Manual may be periodically revised during operation
of the system to address conditions observed during operation.
This Plan has been developed as described in the RD Work Plan. In the following sections,
preliminary O&M activities, as well as monitoring, record keeping, and reporting
requirements are described for the AS/SVE system to be operated as part of the remedy for
the Site.
In addition, as part of the O&M Manual, a Health and Safety Plan (HASP) will be included.
The HASP will outline health and safety procedures to be followed while performing O&M
activities once the system has become fully operational.
3.1 AS/SVE SYSTEM OPERATION AND MAINTENANCE
Major mechanical components of the AS/SVE system include the air sparging and soil vapor
extraction package systems, the granular activated carbon (GAC) units, and the associated
valves and instrumentation. Equipment manufacturers will supply O&M manuals and
provide representatives to inspect the final installation, supervise the initial operation, and
train personnel as required by the RD technical specifications.

The AS/SVE system has been designed as an automated system and, therefore, manual
operation should be minimal. The PLC will be programmed to operate the system as
described in Section 16900 of the RD technical specifications. The initial adjustments to the
AS/SVE system will be performed during operational testing. In general, the AS/SVE system
will be operated at various flow rates in order to evaluate the performance of the installed
Phase I AS/SVE system. Once this operational testing has been completed, the system will be
deactivated to allow correction of any software or hardware not performing according to the
RD.
The Phase I Performance Testing Plan will be finalized and the AS/SVE system will be started
again. Pressure and flow information will be collected from the AS and SVE wells and the
monitoring probe network during this portion of the initial startup period and Phase I
performance testing and will be used to evaluate the effectiveness of Phase I as described in
Section 3.5 of the RD.
Once the initial startup period and Phase I performance testing has been completed, the
AS/SVE system will be evaluated to determine if Phase II is required.
The flow rate and pressure for the system will be monitored using in-line meters located at the
wells and in the equipment area. These flow and pressure meters will transmit information to
the on-site control system and these data will be recorded electronically by the SCADA
system at a routine interval. The flow rates and pressures detected by the meters will be
monitored and compared automatically. Normal operating ranges will be developed based on
manufacturer specifications and data collected during the Phase I Performance Testing. If an
out-of-range condition exists, the system will relay the alarm condition to the appropriate
controller (Brown and Caldwell personnel) and, based on the type of alarm, the system will
automatically shut down according to the RD specifications. Data files will be downloaded
periodically by the operator via a computer modem. A copy of these data files will be used to

evaluate system performance as described in the Phase I Performance Testing Plan to be
prepared subsequent to this RA Work Plan.
The air sparging and the soil vapor extraction package systems will be operated by the on-site
control system. The AS/SVE wells will be equipped with valves for manual throttling to
adjust the flow to the desired rate. It is expected that the SVE blower will be operated at a
constant extraction rate that will be adjustable by the air bleed-in valve so steady-state
conditions will be maintained for continuous operation. As a precautionary measure,
however, a pressure controller will be included as part of the control system to deactivate the
AS/SVE system in the event that an out-of-range pressure condition exists indicating that the
system is not operating properly.
The AS/SVE equipment will be an automated system enabling remote access to flow, pressure
and temperature information. Instrumentation will be installed in each of the AS/SVE wells
identified in the RD, in addition to the instrumentation located in the AS/SVE equipment
area. Each instrument will send information to the on-site control system. Remote access to
data files will be provided via a computer modem and data files for flow, temperature, and
pressure information will be downloaded as previously described.
Maintenance will be performed as required and will be based on observations of system
performance made via the remote monitoring/ control (SCAD A) system and on-site
inspections. It is anticipated that the following maintenance activities will be required:
• condensate removal
• compressor/blower repair or replacement
• valve and instrument repairs
• GAC changeout.
As previously stated, the control system will be accessible via a computer modem. Operation
of the system will be checked remotely to verify that the system is functioning properly. In

addition to manual verification by the operator, the control system will include an autodialer
to alert the operator of a stoppage of AS/SVE, a leak in the line, or power failure. Therefore,
any discontinuation of equipment operation will be detected and addressed. However, due to
the nature of the groundwater plume (i.e., very slow migration), there is no imminent hazard
related to an interruption in operation. Therefore, no contingency measures are needed for
downtime to implement repairs or maintenance to the AS/SVE system. If a stoppage of
operation is detected and cannot be rectified remotely, a local service contractor will be
contacted to visit the Site and restart the system.
The piping and instrumentation diagram (P&ID) prepared as part of the RD will be revised to
numerically identify each valve and other equipment items following construction. The
P&ID along with the O&M Manual prepared after construction will be formatted for use by
maintenance personnel. Model numbers for the compressor, blower, instruments and other
eqmpment will also be included in the O&M Manual for replacement ordering, when
required.
Operation and maintenance activities associated with the AS/SVE system will be conducted in
accordance with the O&M Manual to be prepared following Phase I construction. Activ_ities
performed at the Site will be documented in a logbook to be retained in the equipment area at
the Site.
3.2 AS/SVE SYSTEM MONITORING
The primary objective of the AS/SVE system is to treat the source area of affected
groundwater at the Site. The AS/SVE well locations were chosen to treat the source area.
The effectiveness of the operating AS/SVE system will be monitored in conformance with the
Phase I Performance Testing Plan to be submitted subsequent to this RA Work Plan. The
measurements will be evaluated to determine whether sparge air is being captured by the SVE
wells.

AS/SVE system monitoring data will be collected during two stages of implementation:
• Operational Testing
• Phase I Performance Testing.
These are further described below.
3.3 OPERATIONAL TESTING
Prior to operating the AS/SVE system, barometric pressure will be monitored at hourly
intervals for approximately seven days to identify long-term trends and/ or barometric effects
prior to initiation of operational testing. Upon completion of this pre-operation data
collection, the AS/SVE system will initially be operated using a stepped series of varying flow
rates in order to collect data for determination of well vacuum and flow rate relationships.
Readings will be collected at ten-minute intervals from the SVE wells and will be recorded
along with the associated flow rate. Upon completion of the test, the system will be turned
off and monitored until the vacuum is dissipated. Air will be injected into the AS well heads
in a pulsed mode. The AS wells will be bypassed during the operational testing so the air will
not actually be injected into the groundwater. Flow rates, vacuums, and temperatures will be
continuously monitored during the test. Data for the operational testing will be collected
until the monitored data indicate that the system has reached a steady-state or
pseudo-steady-state condition (i.e., as close to steady-state as reasonably practicable). The
operational testing process is expected to take approximately one to two weeks to complete.
The operational testing will serve to check that the installed software and hardware function
according to the RD.
The operational testing will be used to evaluate the pneumatic permeability of the vadose zone
in the source area and to evaluate the radius of influence for the SVE wells as compared to the
radius of influence estimated from the pilot tests data. The radius of influence will be

calculated for individual SVE wells based on the new data and the capture zone will be
evaluated.
Initial operational testing results and evaluation will be included in the Phase I Performance
Testing Plan.
3.4 PHASE I PERFORMANCE TESTING
According to the existing groundwater monitoring plan, groundwater samples will be taken
and evaluated semiannually.
During each evaluation (or more frequently if called for by the Phase I Performance Testing
Plan), monitoring probes will be evaluated to confirm establishment and maintenance of
sparge air capture.
Monitoring results will be reported to the USEPA semiannually, commencing approximately
three months after the completion of the Phase I Performance Testing. Reporting will include
tabulated pressure and flow measurements; results of monitoring probe, individual and
combined contaminant mass removal from SVE wells; and a figure demonstrating sparge air
capture zones.

4.0 PERFORMANCE STANDARDS VERIFICATION PLAN
The Performance Standards Verification Plan required by the SOW is made up of the
Monitored Natural Attenuation Plan submitted in the RD, the Phase I Performance Testing
Plan (to be prepared), and the Phase II Performance Testing Plan (if required). The
Performance Standards Verification Plan also includes a Sampling and Analysis Plan defining
the field sampling and data gathering methods to be used. The Performance Standards
Verification QA/QC Plan will consist of the QAPP used throughout the project to date.
4.1 MONITORED NATURAL ATTENUATION PLAN
The Monitored Natural Attenuation Plan presented in the RD is reiterated here for the
convenience of the reader. This plan is consistent with semiannual sampling that has been
ongoing since the fourth quarter of 1998.
The plan for monitored natural attenuation will be implemented by performing semiannual
sampling of selected monitoring wells for natural attenuation parameters. The selected
momtormg wells, sample frequency, and analysis will be reevaluated and adjusted as
appropriate after the first two years of monitoring (2002) and again after five years of
momtonng (2005). As data are evaluated, the list of wells may change to accommodate
fluctuations in groundwater levels and conditions during testing. In addition, modifications to
the sampling plan are anticipated in order to monitor the effectiveness of the source control
measure once the remedy is in place. The tasks associated with monitored natural attenuation
at the Site include the following:
• sampling of the monitoring wells listed in Table 4-1
• field measurements and laboratory analysis of the samples usmg the analytical
method references shown in Table 4-2

4.2 PHASE I PERFORMANCE TESTING PLAN
The Phase I Performance Testing Plan will be prepared following the Phase I installation. In
general the plan will consist of sampling the monitoring probes installed as part of Phase I.
Additionally, groundwater samples may also be obtained from the SVE wells. Following the
Phase I installation, groundwater will be sampled from the Phase I SVE wells and monitoring
probes to better delineate the source area.
The fourteen monitoring probes will also be used to collect vapor samples and obtain vacuum
measurements. The intent of the Phase I design is to capture the sparge air with the ten.SVE
wells surrounding the two sparge points. However, due to the subsurface characteristics at the
site, migration of the sparge air cannot be accurately predicted. The data gathered from the
monitoring probe network will indicate whether the sparge air is being captured by the SVE
wells.
Detailed sampling and analysis procedures will be included in the Phase I Performance Testing
Plan.

5.0 REMEDIAL ACTION SCHEDULE
A preliminary schedule for implementation of RA activities described in the RA Work Plan
has been prepared as depicted on Figure 5-1. The schedule is based upon current knowledge of
Site conditions. Unforeseen conditions may impact the overall schedule. In addition, the
actual schedule is dependent on Agency review and approval schedules and Site access.
Schedule variations resulting from reviews by the USEPA and the NCDENR will be
evaluated and revisions to the construction schedule evaluated. On-Site RA activities will not
begin until approval from the USEPA of this RA Work Plan has been received. The actual
construction schedule will be prepared by the RA Contractor and may vary from this
preliminary schedule based upon the dependencies included in the schedule and RA
Contractor input.

6.0 DESCRIPTION OF COMMUNITY RELATIONS SUPPORT ACTIVITIES
At the request of the USEP A, El Paso and Burlington will assist the USEP A in preparing and
disseminating information to the public regarding the RA activities to be performed. This
includes preparing summaries, maps, data, and attending public meetings. The Administrative
Record for the Site is housed both in the Information Repository maintained at the USEP A

PROJECT DELIVERY STRATEGY
This Project Delivery Strategy provides a detailed description for implementing the RA.
Based on the type, size, and expected duration of this project, El Paso and Burlington propose
to use the following approach:
• The Final Design Submittal was transmitted to the USEPA on March 28, 2000. The
Pre-Final Design was reviewed by the USEP A and was reissued as final with the
response-to-comments added to the final document.
• Based on the requirements of the Consent Decree, the RA Work Plan will be
transmitted to the USEPA and NCDENR within 60 days after the approval of the
Final RD. It has been assumed that the RA Work Plan will be approved by May 10,
2000. Schedule variations resulting from USEPA and NCDENR review will be
incorporated, if required, into the construction schedule.
• Appropriate agencies will be contacted and necessary permits or permit equivalents
· will be prepared, submitted, and approved within an estimated nine-week period.
However, the actual time required for this task will be dependent on those agencies
and, therefore, is beyond the control of El Paso. Required permits are assumed to be
only local building permits. As stated in the RD, permits will not be required due to
the fact that the Site is under the authority of CERCLA. However, the substantive
requirements of the otherwise applicable permits will be achieved.
• Brown and Caldwell has been selected by El Paso as the RA Contractor.
Subcontractors to Brown and Caldwell will be selected by the competitive bid
process. The subcontractors will perform well installation, surveying, and
installation of mechanical, electrical, instrumentation, and control systems.

• Prior to initial mobilization by the RA Contractor and his subcontractors, a Pre-
Construction Meeting will be held on Site with the project participants.
• El Paso will contract the task of construction quality assurance (CQA) to an
independent firm. Construction quality assurance requirements are outlined in the
CQAP. This plan is included as Attachment 3 of the RA Work Plan.
• The RA will be implemented using a phased approach. The Phase I installation is the
basis of the RD. The performance of the Phase I installation will be evaluated, and
following that evaluation, a determination will be made as to whether Phase II is
required.
• RA activities will be continuous from the initial mobilization by the RA Contractor
through completion of Phase I construction and demobilization from the Site.
Several tasks may be performed concurrently.
• The RA Contractor will be responsible for procurement of capital equipment
including the packaged air sparging system, the packaged SVE system, and the
packaged GAC system. Submittals for equipment and materials to be used/installed
as part of the RA will be provided to the CQA Consultant for information as
specified in the Contract Documents prior to procurement. The equipment
necessary to complete the construction is anticipated to be readily available.
• The RA Contractor will be responsible for the health and safety of on-site personnel.
Air emission and spill control requirements will be addressed in the health and safety
plan. The Contractor will be responsible for developing and submitting a Health
and Safety/Contingency Plan in accordance with the Contract Documents.
• Prior to demobilization, a Final Phase I Construction Inspection will be conducted
and preparation of a Final Construction Report for Phase I will begin subsequently.

• Preparation of the O&M Manual will be completed after system operational testing
has been completed and after submittal of the Final Construction Report for Phase I.
• Preparation of the Phase I Performance Testing Plan will be completed after system
operational testing has been completed and after submittal of the Final Construction
Report for Phase I.
• Following the Phase I performance testing period, the effectiveness of the Phase I
installation and the need for a Phase II will be evaluated.
• At this time, El Paso does not anticipate performing any of the RA activities
internally with the exception of project management duties described in Section 2.3
of the RA Work Plan.

3.0 AS/SVE SYSTEM CQA
This section of the CQAP addresses the components of the AS/SVE system and outlines the
CQA program to be implemented with regard to materials selection and evaluation,
laboratory test requirements, field test requirements, and treatment of problems.
3.1 AS/SVE SYSTEM COMPONENTS
The major components of the AS/SVE system are described below.
3. 1. 1 AS/SVE Wells and Monitoring Probes
The dimensions and details of the AS/SVE wells and monitoring probes will be as shown on
the construction drawings. Submittals and quality control testing for the materials used to
construct the AS/SVE wells and monitoring probes will be as identified in the project
specifications. The CQA Consultant will compile the RA Contractor's submittals and quality
control test data for compliance with the project specifications and drawings.
The CQA Consultant will monitor installation of the AS/SVE wells and monitoring probes
for conformance with the dimensions on the construction drawings and the pre-installation
boring for that particular location. The CQA Consultant will document and check the screen
location of each well. The checks of the depth of the various components of the AS/SVE
wells and monitoring probes will be made by the RA Contractor using a tape measure. The
CQA Consultant will observe and record these measurements made by the RA Contractor
and may take independent measurements to check the RA Contractor's work. The CQA
Consultant will also be responsible for performing the following duties during AS/SVE well
and monitoring probe installation:
• observe pre-installation boring

• observe direct push activities and review interpretation of lithology identified to
select screened intervals
• compile boring logs for each AS/SVE well and monitoring probe location (to be
prepared by the RA Contractor)
• provide visual grain size identification of soil penetration test (split-spoon) samples in
the field
• evaluate data obtained from boring logs, testing, and geologic cross-sections.
3.1.2 Compressors, Blowers, Piping, Valves, and Fittings
The CQA Consultant will monitor these RA components during periodic Site visits. The RA
Contractor will provide the CQA Consultant with quality control certificates (to the extent
required by the specifications) for each shipment of compressors, blowers, piping, valves, or
fittings to the Site. The quality control certificate will be signed by a responsible party
employed by the Equipment Vendors and materials suppliers, such as the Production
Manager. The quality control certificate will include product and identification numbers, and
sampling procedures and results of quality control tests, as required by the project
specifications.
The CQA Consultant will:
• Check that the quality control data and certificates have been provided at the
specified frequency for equipment, pipe, valves, and fittings, and that each certificate
identifies the material related to it.
• Review the quality control data and certificates and check that the certified
properties and materials meet the specifications.

Solid-wall pipe (i.e., from the AS/SVE wells to the equipment area) will be nondestructively
tested by the RA Contractor in accordance with the project specifications. Other
nondestructive test methods may be used only when the method· is acceptable to the
Equipment Vendors, materials suppliers, and the CQA Consultant. The CQA Consultant
will check the effectiveness and validity of the test method, and will report any
nonconformance of testing methods to the RA Contractor.
Prior to the installation of the equipment, pipe, valves, or fittings associated with the AS/SVE
system, the RA Contractor will provide the CQA Consultant with:
• product data, including specified materials and properties, measured using test
methods indicated in the specifications or equivalent
• a certification that product data given in the submittals are guaranteed by the
Equipment Vendors and/ or materials suppliers when required by the specifications.
The CQA Consultant will monitor and document that the product data and materials
certified by the Equipment Vendors and/ or materials suppliers to meet the project
specifications, and the measurements of properties by the Equipment Vendors and/ or
materials suppliers are properly documented and that the test methods used are acceptable.
3.1.3 Computer Control System
The CQA Consultant will monitor the installation of this RA component. Submittals and
quality control testing for the materials and equipment used in the computer control system
will be as identified in the project specifications and the approved control system design. The
CQA Consultant will compile the RA Contractor's submittals to document compliance with
the project specifications and drawings and monitor installation and startup of the computer
control system.

3.2 DEFICIENCIES
If a defect is discovered in the AS/SVE system, the CQA Consultant will immediately assess
the extent and nature of the defect. If the defect is indicated by unsatisfactory quality control
data or visual observation, the CQ A Consultant will assess the extent of the deficient area by
additional observations, a review of records, or other means that the CQA Consultant deems
appropriate. After assessing the extent and nature of a defect, the CQA Consultant will notify
the Owner and RA Contractor to schedule measures to correct the work deficiency.
The RA Contractor will correct the deficiency. If a project specification criterion cannot be
met, or unusual conditions hinder work, then the CQA Consultant will develop and present
suggested solutions to the Owner and the USEP A for approval.
The CQA Consultant will also check that installation requirements are met and that
· submittals are provided.

4.0 DOCUMENTATION
An effective CQAP depends largely on recognition of construction activities that should be
monitored and assigning responsibilities for the monitoring of each activity. This is most
effectively accomplished by the documentation of quality assurance activities. The CQA
Consultant will document that quality assurance requirements have been addressed and
satisfied. When on Site, the CQA Site Manager will complete daily reports that include
descriptive remarks, data sheets, and observation logs to document that monitoring activities
have been carried out. The CQA Site Manager will also maintain a file of plans and
specifications, CQAP checklists, test procedures, observation logs, and other pertinent
documents at the Site.
4.1 RECORD-KEEPING
