AGENDA TITLE: Adopt Resolution Approving Technical Services Task Order with
Treadwell & Rollo, Inc., for Central Plume Soil Vapor Extraction, Phase 1, and
Appropriating Funds ($380,000)
MEETING DATE: September 7, 2005
PREPARED BY: Public Works Director
RECONMAENDED ACTION: That City Council adopt a resolution approving a technical services
task order with Treadwell & Rollo, Inc., for Phase 1 Soil Vapor
Extraction for the Central Plume PCEITCE remediation and
appropriating funds.
BACKGROUND INFORMATION: The City has a master agreement with Treadwell & Rollo, Inc., for
various technical services pertaining to the PCEITCE contamination.
As we continue to move into the remediation phase, staff is
exploring various means to perform the work. However, the
Regional Board is pressing the City to restart and operate the existing soil vapor extraction system
located at Guild Cleaners. This task order will do that for the rest of FY 05106, as well as provide
additional analytical data to design the larger, final soil vapor extraction system.
The attached scope of work details the work to be done. Part of the work entails designing and installing
a minor expansion of the Guild system to connect additional SVE wells already installed by other parties.
FISCAL IMPACT: All costs are included in the Central Plume Fund set up under the settlement
agreement. The total of work estimated by Treadwell & Rollo is just under
$349,000. The recommended appropriation includes a 9% contingency.
FUNDING: Central Plume Fund $380,000

Subject: Proposed Scope, Schedule and Budget
Central Plume Phase I Soil Vapor Extraction (SVE) Program
Lodi, California
Dear Mr. Prima:
Treadwell & Rollo, Inc. (Treadwell & Rollo) is pleased to submit this proposal to implement
Phase I of the soil vapor extraction (SVE) program for the Central Plume Area in Lodi,
California. The purpose of Phase I will be to mitigate the current calculated indoor air risk
determined to exist in certain buildings, respond to the Regional Water Quality Control Board
(RWQCB) request that the current system be restarted as soon as possible to mitigate the indoor
air risk, and provide operational data for the design of a long-term remediation program to be
implemented in 2006. In developing this program to implement Phase I, we have used the
following assumptions:
oo The Phase I system will be operated for up to one year, while a second, full-scale
remedial program is designed and implemented;
oc The LFR Levine -Fricke (LFR) and ERM -West, Inc. (ERM) SVE wells are usable with
surface modifications only, and no new SVE wells will be installed;
oo The existing SVE pad and equipment used by LFR will remain in the same location;
oo The existing granular activated carbon (GAC) system is suitable for this work and new
GAC vessels with fresh GAC are required during the system start up; and
oc The existing blowers and other equipment, including air -water separator, water storage
tank, and the majority of ancillary equipment, will meet the design needs of the combined
system.

The proposed scope of work for preparing and initiating operation of the Phase I system
includes:
Task 1 - preparing and restarting the LFR SVE system currently on site;
Task 2 - design a `fine-tuned' SVE system, relying on existing SVE wells, vacuum
monitoring wells, and the equipment already installed at the site;
Task 3 - modifying the existing SVE system, as needed, to operate until the full-scale SVE
system is constructed;
Task 4 - initiating operation of the Phase I SVE system;
Task 5 - preparing a start up report; and
Task 6 - overseeing the operation and monitoring of the Phase I system for a period of up to
twelve months.
SCOPE OF WORK
Our proposed tasks to implement the scope of work are as follows.
Task 1— Prepare and Re -Start Existing SVE System
Treadwell & Rollo will prepare and re -start the existing SVE system in order to evaluate the
influence of the SVE system at SVE and vapor monitoring locations farther away from the active
SVE wells than were available during the pilot testing of the system. The evaluation of data will
focus on confirming the interpolated radii of influence (ROI) previously calculated, determining
the effective area of influence of the LFR SVE system, and determining whether ERM wells
should be added to the LFR SVE system to sufficiently mitigate the current calculated indoor air
risk determined to exist in certain buildings.
Treadwell & Rollo will prepare the SVE system for start-up through the following tasks:
oo Preparing a Health and Safety Plan for use while restarting and operating the SVE
system.
oo Confirming/renewing the Air Pollution Control District (APCD) discharge permit.
oo Cleaning the treatment compound, which has accumulated significant vegetation.
Mr. Richard Prima T"UWWkW%)ft
Public Works Department
City of Lodi
12 August 2005
Page 3
oo Opening all the wells to confirm pipe diameter and total depth, and that fittings and
gauges for measuring temperature and vacuum, and collecting vapor samples, are
operable on the wellheads and manifolds.
oo Checking all above ground piping for damage due to weather exposure.
oo Confirming that the air/water separator for specified valves is properly connected,
operable, and appropriately labeled; check that the drainage is unobstructed; and confirm
that the air/water separation system has been drained.
oo Checking the blowers and ancillary equipment to confirm their current condition and
operability (e.g., vibration isolation devices, casing and silencers undamaged, proper belt
tension, protective covers installed, pump rotation verified, silencers and sound proofing
connected properly, and coupling alignment is level).
oo Contracting with a licensed electrician familiar with SVE systems to check the electrical
system, including continuity checks, protective covers, unit disconnect, grounding,
lockouts, wiring integrity between components and supply, and appropriate lighting.
oo Checking the vapor control system including the use of flexible lines and connectors for
changing position of lead, interim, and lag activated carbon vessels.
oo Checking for appropriate operation and maintenance equipment including spare blower
air filters, blower belts, etc., and identify what additional equipment is needed prior start
UP.
0o Identifying any system repair and replacement work that must be done prior to system
start up. System repair and replacement work, if required, has not been included in this
proposal.
0o Contracting for operating and monitoring the Phase I SVE system with vendors familiar
with the system.
Prior to start up of the existing system, Treadwell & Rollo will collect vadose-zone data without
the SVE system operating to provide baseline data for evaluating the operation of the SVE
system with respect to existing vadose zone conditions and the progress of the remediation. Data
collection will include:
Mr. Richard Prima T"UWWkjk&
Public Works Department
City of Lodi
12 August 2005
Page 4
oo Purging and sampling up to 18 SVE and vapor monitoring wells to monitor volatile
organic compounds (VOCs), methane, carbon dioxide and oxygen using field monitoring
instruments.
oo Collecting soil gas samples from up to 18 SVE and monitoring wells for chemical
analysis at a fixed laboratory for VOCs by Method TO -15.
oo Collecting groundwater levels at up to 10 groundwater monitoring wells.
To initiate renewed operation of the existing system, Treadwell & Rollo will start up the LFR
system, monitor airflow and vacuum response in LFR and ERM SVE and vacuum monitoring
locations, and collect one additional round of groundwater levels at up to 10 groundwater
monitoring wells. After initial start up, Treadwell & Rollo will perform two performance tests
with the system running, including:
oo A constant rate test (duration approximately 2 hours) at FSEW-3 while monitoring ERM
wells SVE-1 and SVM -5 through SVM -7 and LFR wells; and
oo A constant rate test (duration approximately 2 hours) at PSEW-IA and PSEW-1B while
monitoring ERM wells SVE-1, SVE-2, and SVM -3 through SVM -7 and LFR wells
PSEW-4 through PSEW-9.
After testing, Treadwell & Rollo will select vacuum/flow parameters for system operation while
modifications to the system are evaluated and designed. The existing system will be operated
and maintained by the selected contractor during the design and initial modification tasks under
the budget for Task 6 — Phase I System Operation and Monitoring. During this time, monitoring
will be performed in accordance with the existing APCD permit, including monitoring every
four days for flow parameters, vapor stream VOC content, and VOC capture by the GAC
treatment vessels.
Task 2 - Designing the Phase I SVE System
Based on evaluation of the information collected and reviewed in Task 1, Treadwell & Rollo will
design a Phase I SVE system, with the primary goal of mitigating the current chronic indoor air
risk determined to exist in certain buildings and developing long-term operational information
that will facilitate the design of the long-term remediation program. Based on the existing well
layout (Figure 1), well construction information, and technical data generated in the pilot tests,
we will:
Mr. Richard Prima TNNWWMW%)W
Public Works Department
City of Lodi
12 August 2005
Page 5
oo Calculate design flow rates that will allow adequate air transfer based on the vadose zone
interval screened.
oo Evaluate and select a combination of LFR (PSEW-IA, PSEW-1B, PSEW-1C, FSEW-2,
FSEW-3, PSEW-4 through PSEW-9) and ERM (SVE-1 and SVE-2 and SVM -3 through
SVM -7) wells to be used as SVE and vacuum monitoring wells to achieve sufficient
mitigation of the indoor air risks with the blowers currently installed at the site, if
possible.
oo Evaluate whether any of the existing wells should be used as inlet wells to reduce "dead
zones" or increase pressure gradients.
oo Evaluate extraction pulsing between wells or groups of wells, based on system operating
limits and effectiveness of expected vapor removal.
Treadwell & Rollo will then prepare the necessary documents for implementing the Phase I
system design, which will include:
oo Application for changes to the existing APCD discharge permit, if needed;
oo Recommendations and specifications for equipment changes, if required, for the modified
SVE system operation; and
oo Specifications and drawings for piping and well modification.
Task 3 — Modifying the Existing SVE System
To prepare for any modifications to the existing SVE system, Treadwell & Rollo will complete
appropriate permitting paperwork (air permit modifications and construction permits, as needed);
prepare bid documents for modifying the existing SVE system; and select, subcontract and
oversee the modification of the SVE system and ERM wells and the construction of necessary
trenching and plumbing to connect ERM wells chosen to be SVE wells into the LFR SVE
system.
For estimating costs of installation, Treadwell & Rollo estimates approximately 700 feet of
trenching and extraction line installation (assumes all seven ERM wells are plumbed to the
treatment system through underground piping). We anticipate that this scope may be reduced in
the design process by decreasing the number of SVE and vacuum monitoring wells that will be
added to the existing system and reducing the amount of below grade piping required.

Task 4 — Initiating Operation of the Phase I SVE System
Treadwell & Rollo will start up the Phase I system by performing the following activities.
oo Sequentially starting up the system to test the equipment, confirm operational parameters
and gather operating data, including monitoring the exhaust from the GAC with a PID to
confirm that VOCs are being captured; monitoring vacuum/pressure gauges and
temperature gauges; measuring air flow velocities in the piping; and other performance
testing.
oo Evaluating the effects of pulsed SVE applications on discrete wells and groups of wells,
if required.
oo When the system is running at or close to the expected operating conditions (system
equilibrium may take several days), we will measure flow rates, vacuum, VOC
concentrations (using field instrumentation), and temperature at each SVE well,
monitoring point and combined at the manifold(s).
oo Collecting soil gas samples from up to 18 SVE and monitoring wells and four additional
samples from the GAC system (influent, between the GAC vessels, and effluent) for
chemical analysis at a fixed laboratory for VOCs by Method TO -15.
Task 5 — Data Evaluation and Start -Up Report
During the initial operation of the Phase I SVE system, Treadwell & Rollo will be evaluating the
data generated and making modifications to improve system performance. When the system has
reached equilibrium, we will then transition the system into operations and maintenance mode
and prepare a start-up report to document performance for use in the full-scale design process.
The report will include:
oo Site plans showing locations of air -extraction wells and vacuum measuring points, paved
areas, buildings, and structures that may act as a surface seal and/or an infiltration barrier,
and buried utility trenches that may act as zones of higher permeability or short-
circuiting.
oo Plans and cross sections showing vacuum distribution in the subsurface at equilibrium.
oo Plots of. 1) volume of air extracted versus time; 2) cumulate volume of air extracted
versus time; 3) concentrations of contaminants of concern versus time; 4) mass removal
rate of contaminants of concern versus time; and 5) cumulative mass of contaminants of
concern removed versus time for each SVE well.
Mr. Richard Prima T"UWWkW%)W

oo Tabulated well construction information if different than previously reported.
oo Tabulated flow rates, vacuum/pressure readings, soil gas temperatures, times of readings,
ambient barometric pressure, and the ambient temperature.
oo Tabulated oxygen, methane, carbon dioxide, and VOC concentrations.
oo Tabulated water levels.
oo Tabulated influent and effluent discharge concentrations from the soil gas vapor
treatment system.
oo Tabulated liquid recovery rates from the air -water separator.
oo As -built plans for the newly constructed and modified work.
Task 6 — Phase I System Operation and Monitoring
After start up, Treadwell & Rollo will oversee the contractor(s) performing operation,
maintenance, and monitoring activities and servicing the GAC vapor treatment vessels. To
obtain efficient operation and meet the APCD permit requirements (i.e., that the system
treatment vessels meet treatment efficiencies of no less than 99 per cent for PCE, a minimum
flow rate of 125 scfin, a minimum exit velocity of 5,730 fpm, and that PCE emissions not exceed
13.3 ppmv), the following activities will be performed:
oo Monitoring will be performed on the system at least once every four days in accordance
with the APCD permit requirement. Monitoring will include now parameters for the
total system flow (and for each pulsed well group, if pulsing is utilized), and VOC
concentrations by field instruments at selected wells and the total vapor stream at the
manifold, and after each GAC vessel (this activity may be performed by City personnel);
oo Vapor samples will be collected for laboratory halogenated VOC analysis from the total
system at the manifold and after each GAC vessel on a quarterly schedule (this may be a
task that the analytical laboratory can perform);
oo The vacuum influence and vapor flow parameters will be monitored throughout the well
field quarterly;
oo The blowers will be serviced quarterly;
Mr. Richard Prima TNNWWMW%)W
Public Works Department
City of Lodi
12 August 2005
Page 8
oo GAC vessels will be renewed as needed, based on the weekly and quarterly monitoring.
Our cost estimate assumes a carbon consumption rate of 230 lbs/day or roughly twice the
rate LFR calculated for carbon consumption during the pilot test;
oo Water collected in the accumulation system, and solvent accumulated in a solvent
recovery system (if included in the interim design), will be sampled, removed, and
disposed as needed, based on the accumulated volumes; and
oo Maintain records of the cumulative running time and the measured influent and effluent
concentrations in accordance with the APCD permit.
Treadwell & Rollo will prepare a quarterly technical report for submittal to the City, the APCD,
and the Regional Water Quality Control Board.

ESTIMATED COSTS
We have estimated project costs using conservative assumptions, including a 20% contingency
for construction costs and starting up the modified system (Tasks 3 and 4), a 10% contingency
for operations and maintenance costs (Task 6), and the design assumption that all piping is
installed below grade. Construction and operations and maintenance costs are based on
discussions with Pacific States Environmental Contractors, the firm that built and operated the
LFR system, and assume that GAC change -outs are needed on a weekly basis. The GAC
change -out frequency is likely conservative, as GAC usage typically drops over time. However,
the HVOC soil gas concentrations known to exist in the alley area are very high, and the
conservative GAC use assumption is appropriate for this estimate.
