COUNCIL COMMUNICATION
AGENDA TITLE: Adopt Resolution Authorizing Additional Task Order with Treadwell & Rollo
Regarding PCE/TCE Cleanup ($167,000) and Appropriating Funds ($180,000)
MEETING DATE: March 3, 2010
PREPARED BY: Public Works Director
RECOMMENDED ACTION: Adopt a resolution authorizing an additional task order with
Treadwell & Rollo regarding PCE/TCE cleanup in the amount of
$167,000 and appropriating funds in the amount of $180,000.
BACKGROUND INFORMATION: Staff and our consultants are moving forward on the implementation
of Phase I of the PCE/TCE cleanup program. Design of the Phase I
permanent facilities is complete and bids were opened on
February 23 for the construction of the facilities. At the same time,
operation of the temporary soil vapor extraction and treatment (SVET) system will need to continue for
approximately one additional year.
Proposed Task Order No. 20, attached as ExhibitA, provides for the continued operation and maintenance
by Treadwell & Rollo of the SVET system for a period not to exceed one year. The current task order for
maintenance and operation of these facilities expires on March 31, 2010. It is expected the temporary
SVET system will be abandoned within the 12 -month period covered by Task Order No. 20 and, therefore,
it will expire once the Phase I facilities are constructed and operational. The estimated cost is $167,000
but will be less assuming the Phase I facilities will be operational prior to March 31, 2011. The requested
appropriation includes additional funds to cover contingencies.
FISCAL IMPACT:
FUNDING AVAILABLE:
FWS/pmf
Attachment
Operation and maintenance costs will increase and are funded by
PCEPTCE Cleanup funds.
Requested Appropriation: Central Plume Fund (190) – $180,000

FROM: Christopher Glenn, P.E., LEED GA
DATE: 19 January 2010
PROJECT: Proposal for Guild SVE System Operation & Maintenance from April '2010 to March 2011
17 South Church Street, Lodi, California
Proposed Lodi Task 20
SUBJECT: Scope, Schedule, and Cost Estimate for Lodi Task 20 No. of Pages: 3
This memorandum presents the proposed scope, schedule, and costs for Operation and Maigtenance
(0&M) of the Guild Soil Vapor Extraction (SVE) system in Lodi, California for an additional 12 months. I f
approved, this will be identified as Lodi Task 20 - Guild SVE 0&M.
BACKGROUND
Treadwell & Rollo (T&R) operates the Guild SVE system on behalf of the City of Lodi to remediate
tetrachloroethylene (PCE) contamination in soil and soil vapor in the Centrai Plume Source Area in Lodi,
California. The SVE system is located in the parking lot of Guild Cleaners, located at 17 South Church
Street, Lodi, California (the Site). The SVE system is operated under a permit by the San Joaquin Valley
Air Pollution Control District (SJVAPCD), issued on 31 May 2006, and revised on 3 November 2008. The
permit requires monthly monitoring and vapor sample collection. The permit also requires treatment of
extracted vapors using three granular activated carbon (GAC) vessels. The SJVAPCD requires tabulation
of monthly PCE influent and effluent concentrations, monthly PCE control efficiency, i monthly influent and
effluent flow rates, and cumulative run time. T&R's current budget for Guild SVE System O&M covers
operations through March 2010. This proposal will cover an additional 12 months of 0&M through March
2011.
We understand that the City cf Lodi is currently soliciting bids for the construction of the Source Area SVE
System, which will ultimately replace the Guild SVE system. I f this new system is completed and the
Guild SVE system operations are discontinued prior to March 2011, T&R would not use the full budget
requested in this proposal,
SCOPE OF WORK
The scope of work for the Guild SVE O&M includes several tasks that are listed below:
• Routine Site Visits - A T&R field technician will visit the Site one day per month to monitor flow
rates, pressures, vacuums, temperature; and to check the operating conditions of the system and
note repairs to be performed, if required. The field technician will also collect four vapor samples
and perform minor repairs and/or site maintenance, as needed.

GAC Changeout and Waste Disposal - GAC vessels are changed when the effluent from the
second of three vessels contains PCE concentration above the SJVAPCD permit level. The third
carbon vessel serves as a backup. Based upon the SVE system carbon usage in x,009, we have
assumed three carbon changeouts will be required from April 2010 to March 2011. If more than
three GAC changeouts are required during the year, additional budget may need to be
authorized. Preparation of the GAC waste manifest and profile is included in this task. The
manifest is required prior to the transport of spent GAC and is signed by Charlie Swimley of the
City of Lodi. GAC sample collection, analysis, and profile documentation are performed
periodically for the renewal of the GAC profile. Also, the scope includes yearly disposal of water
collected from the knock out drum. T&R assumes that disposal fees for this task will not exceed
$2,000 per year.
Laboratory Analysis — This includes collecting four vapor samples in Tedlar bags and sending
them to Air Toxics Laboratory (Folsom, California) for TO -15 analysis. The turn -around time for
this analysis is 10 days, and the samples will be picked up by a lab courier.
Non — Routine Site Visits For Repairs - This includes non -routine, unexpected repairs to the
Guild SVE system required for continued proper operation. T&R will only repair the minimum
required for proper operation because the remaining expected operational lifetime of the Guild
SVE system is one year or less. T&R assumes not more than six non -routine visits for the 12
month period and no more than $15,000 in repair work. Additional visits or repairs will require
an increase to the budget.
• Air District Compliance, Reporting and Inspections —This includes the evaluation of
monitoring data ,with the SJVAPCD permit for compliance. I f there is an event of non-
compliance, T&R will act immediately to remedy the problem. T&R will provide periodic reports
as requested by SJVAPCD. T&R will facilitate SJVAPCD inspection of the SVE system, which is
assumed to occur not more than once in the 12 -month period.
• Reporting and Calculations —T&R will maintain a log of PCE mass removal from the Guild
SVE system and report periodicallyto the City of Lodi. T&R will also manage logs of monitoring
data, field notes, laboratory results, and control efficiency as required by the SJVAPCD. On a
quarterly basis, T&R will provide a summary of SVE operations to Stantec, for inclusion in their
quarterly groundwater monitoring reports.
• Project Management and Communication - This includes maintaining effective
communication with the City of Lodi, and responding to questions and requests for information,
as needed.
SCHEDULE
This proposal covers SVE O&M from April 2010 through March 2011:
DELIVERABLES
T&R will provide a summary of SVE operations to Stantec at the end of each quarter, for inclusion in their
quarterly groundwater monitoring report. Information included will be a brief text section describing the
SVE operations during the quarter, operations and field logs, and a calculation of estimated PCE mass
removal by the system for the quarter,
T&R will also provide information upon request from Lodi, SJVAPCD, or other agencies. These include:
1) PCE Removal Efficiency (required by SJVAPCD)
2) Operation logs of flow rates (required by SJVAPCD)
3) Cumulative PCE mass removal (periodically requested by City of Lodi)
4) SJVAPCD permit renewal.
COST ESTIMATE
Our estimated fee for this scope of work will not exceed $167,000. This corresponds to approximately
$13,920 per month. Due to the non-linear nature of O&M expenditures, costs may exceed $13,920 in
any given month. The assumptions behind this cost are included in the scope cf work section above.
