FROM: James Rabe, Director of Public Works
DATE: January 18, 2018
RE: Approve Engineering Services Agreement with AECOM Technical Services, Inc. (AECOM) for 2018
Knapp Street Quarries and Timmerman Landfill Operations and Maintenance Support ($82,750)
BACKGROUND
The Department of Public Works has utilized AECOM (formerly STS Consultants) for various environmental
engineering needs at the Quarry Park Landfill located on Knapp Street since 1979 and at the Timmerman Landfill
since 1993. The active venting system has been operating at Quarry Park since spring of 2010. AECOM continues
to report no measurement of methane at the various monitoring points. An operational pilot study was completed
between the fall of 2015 and the spring of 2016 to determine if the active venting system could be converted to a
passive system. The study results indicated the system will need to continue to operate in an active setting. It is
anticipated the Wisconsin Department of Natural Resources (WDNR) will require several more years of active
collection of methane gas before considering a reduced operation or switching to passive collection.
ANALYSIS
Previously, agreements with AECOM for environmental engineering services for each landfill were executed and
reported to the Common Council. In an effort to reduce paperwork, staff has worked with AECOM to incorporate
both projects into a single agreement. This agreement will cover the required monitoring and maintenance at both
former landfills for calendar year 2018. The scope of services includes continued methane gas monitoring, reporting
to the WDNR, inspecting the methane collection system, and providing equipment maintenance recommendations.
FISCAL IMPACT
This agreement is for $82,750. The cost for these gas monitoring services will be allocated to the operating budget
(Account 02120470-6401/Garbage Collection & Disposal). This contract amount represents a reduction in fee from
2017 of $7,600. This reduction is made possible through our continual negotiation and utilization of qualified,
competent staff with lower charge -out rates.
RECOMMENDATION
Chapter 12 of the Municipal Code provides that professional services of a specialized nature, including engineering
services, may be procured without the use of formal, sealed quotes. I have reviewed this agreement and in
accordance with Section 12-16 of the Code, I am hereby recommending the Common Council approve this
agreement.
Approved:

AECOM Proposal No.
OPP-708696
Proposal for Knapp Street Quarries and Timmerman Landfill Operations and Maintenance Support during
the 2018 Calendar Year
Dear Mr. Rabe,
AECOM Technical Services, Inc. (AECOM) has prepared this proposal for continued methane monitoring, sampling,
landfill gas collection system operation and maintenance, and reporting at the former Faber Quarry and former
Oshkosh Stone Company Quarry (collectively known as the Knapp Street Quarries) and groundwater and methane
monitoring, sampling and reporting at the former Timmerman Landfill during the 2018 calendar year (CY2018). This
proposal provides a summary of the specific project backgrounds, proposed scope of services and estimated costs for
continued environmental monitoring at each site.
Task 1 — Knapp Street Quarries
Background
The scope of services presented below is based on recommendations provided in the Operation Manual and in
accordance with Wisconsin Department of Natural Resources (WDNR) Solid Waste requirements.
The gas collection system was installed and started operation in 2010. AECOM personnel have continued monitoring
the system and continually work at balancing the gas recovery. The system has had a positive influence on the
reduction of methane gas and thus reduced the risk of methane gas migration off-site. At this time the monitoring
points show methane concentration below 2.5% by volume. The WDNR has conditionally approved a plan toward
reduced operation of the landfill gas extraction system. That plan requires that there is effective gas recovery when
cycling the blower operations (6 -hours on and 4 -hours off) over a 4 -month period and following the closure of sections
of vent piping that have had less than detectable readings for methane for a consecutive 12 -month period. This plan
was initiated in 2015. Prior to and during the test period, system mechanical issues occurred that prolonged the
testing program, which included:
Replacement of the blower motor (twice, covered by warranty).
Replacement of the exhaust stack (collapsed prior to the test commencing).
Modifications to the grease tube operation to provide a constant temperature for the equipment.
AECOM worked with a contractor to make the repairs and modifications. The testing was completed in September
2016. Based on the results of the reduced operation testing and with concurrence from the WDNR the active system
is still required to control landfill gases. Another reduced operation test will be planned in the next 5 years to verify
conditions at that time.
In 2016, it was observed that several of the surrounding monitoring wells', located in sidewalk or parking lot
pavement, flush -mount protective covers were no longer able to protect the integrity of the wells. This is likely due to
age of the structures, damage from snow plowing and damage to the surrounding surface from freeze -thaw cycles
(uneven grade). The repairs to the flush -mount protective covers will be completed in 2018 and 2019 if any savings to
the proposed budgets are realized.

AECOM
In the summer of 2017, a WDNR Solid Waste Engineer inspected the site. AECOM and City Staff completed the site
inspection with the WDNR representative. All items that were identified during this inspection were corrected by
AECOM or City staff, and AECOM prepared a letter detailing the corrective actions and submitted it to the WDNR.
Scope of Services
Methane Gas Monitoring
AECOM proposes to continue to conduct methane monitoring activities based on the schedule provided in the WDNR
conditional approval letter dated April 15, 2014 and as presented in the chart below.

NOTES:
1. At the time of monitoring the gas wells, gas extraction wells, header pipe at the blower station, and the discharge vent pipe, site
conditions will be monitored for the following parameters: ambient air temperature, barometric pressure, trends in barometric
pressure, ground surface conditions, type of meter used, and latest meter calibration date.
2. Monitoring has since been discontinued in the following gas monitoring wells: GW -1, GW -3, GW -4, GW -5, GW -6, GW -7, GW -8,
GW -15, and GW -16 and the following observation wells, OW -1 and OW -2, which were abandoned.
3. WH -7 and VV -2 do not exist.
At each gas monitoring well, and system sampling port the vacuum pressure, initial percent of the LEL of methane
(percent LEL methane), percent methane gas (percent methane), percent oxygen (percent 02), percent of carbon
monoxide (percent CO2), air flow (CFM), and groundwater levels will be measured. The LEL is the minimum
concentration of a particular combustible gas or vapor necessary to support its combustion in air. The LEL of
methane gas is 5% methane by volume. Observations (such as ground condition, barometric pressure, and
monitoring well conditions) will also be recorded.
After initial readings are recorded, monitoring wells will be purged with a pump at a rate of two liters per minute.
Continuous percent LEL methane is to be measured as the well is purged. A final reading will be recorded when
consecutive methane readings are within ±10% LEL. Final measurements include percent LEL methane, percent
methane gas, percent CO2, and percent 02. The length of time required to achieve the final reading is typically
unique to each well.
Based on the 2017 WDNR site inspection, AECOM has added a checklist to be completed during each site visit. The
checklist includes all items identified during the site inspection. If deficiencies are noted, AECOM staff will inform the
City and develop and implement a solution.

AECOM
Schedule and Reporting
Methane sampling and system O&M will be completed in accordance with the above schedule through December
2018. The monitoring data will be summarized and electronically submitted to the City and WDNR GEMS database
on a semiannual basis. On an annual basis, a report will be submitted to the WDNR (including cover letter with
discussion and conclusions). AECOM will immediately notify the City of any new methane wells that indicate an
exceedance of the 25% LEL.
Task 2 — Timmerman Landfill
Background
AECOM has been assisting the City with environmental services related to the Timmerman Landfill since 1978.
These services have included groundwater and methane monitoring, landfill cap thickness verification, laboratory
testing, data review, and closure planning. In response to the WDNR Notice of Violation dated August 2, 2006,
AECOM completed a Site Assessment Report (SAR) in compliance with Wisconsin Administrative Code Section NR
700 and subsequently installed three additional groundwater monitoring wells. In 2008 and early 2009, AECOM
completed the closure of the site under the WDNR Remediation and Redevelopment (RR) program and the site was
transferred to the WDNR Solid Waste Program. In 2010, AECOM recommended the abandonment of six monitoring
wells. The WDNR subsequently requested additional investigation regarding the presence of a passive methane
collection trench, which AECOM completed using test pits. Based on the results of the test pit investigation and
AECOM's recommendation in 2010, the WDNR approved the abandonment of the six wells and required the
installation of two gas probes (in addition to the four already installed at the site) for additional methane monitoring in
a letter dated February 2013.
In the summer of 2017, a WDNR Solid Waste Engineer inspected the site. AECOM and City Staff completed the site
inspection with the WDNR representative. All items that were identified during this inspection were corrected by
AECOM or City staff, and AECOM prepared a letter detailing the corrective actions and submitted it to the WDNR.
Scope of Services
This proposal includes two rounds (semiannual) of groundwater monitoring, subcontract analytical laboratory services,
and project reporting obligations through CY2018. In addition, landfill gas will be monitored quarterly and reported to
the WDNR until approval to discontinue the methane monitoring and abandon the wells is achieved. AECOM
submitted a gas monitoring reduction request in 2016. The request was subsequently denied by the WDNR as
methane monitoring is required to be completed quarterly by Wisconsin Administrative Code NR 500.
Groundwater samples will be collected according to the WDNR-approved monitoring requirements in the chart below:
Location Parameters Frequency
Alkalinity, Chloride, Hardness, Groundwater
MW -1, PZ -4, PZ -5, MW -6, MW -7, PZ -7, Elevation, field pH, field Temperature, field Semi-annually
PZ -7D, MW -8, PZ-1,PZ-8, PZ -9, conductivity
SQDMW-1, PZ -10
Volatile Organic Compounds (VOCs) Annually
MW -9, MW -10 Groundwater elevation, field pH, field conductivity Semi -Annually
VOCs Annually
Groundwater monitoring wells will be purged prior to collecting the samples and field monitoring parameters.
Gas monitoring points (GP -1 through GP -6) will be monitored quarterly for methane, oxygen, and carbon dioxide, per
the methods described above under the Knapp Street Quarries Scope of Services, as required by the WDNR.
Readings for barometric pressure, pressure trend, and temperature will also be collected during monitoring activities.

AECOM
Based on the 2017 WDNR site inspection, AECOM has added a checklist to be completed during each site visit. The
checklist includes all items identified during the site inspection. If deficiencies are noted, AECOM staff will inform the
City and develop and implement a solution.
Schedule and Reporting
Groundwater sampling will be completed twice annually (April and October), and gas monitoring will be completed on
a quarterly basis (January, April, July, and October) through December 2018. The monitoring data will be summarized
and electronically submitted to the City and WDNR on a semi-annual basis.

Future Services to be Combined Knapp Street Quarries and Timmerman Landfill
We anticipate the installation, start-up, and operation of the Kienast and Paulus Quarry landfill gas collection system
will occur in 2018. Startup, operation, and maintenance costs through 2018 associated with the Kienast and Paulus
Quarry landfill gas system will be incorporated in the construction management agreement for that project. In 2019
these services are anticipated to be incorporated in the 2019 Landfill Operation and Maintenance Agreement. By
combining these services on the multiple sites, AECOM anticipates there will be cost savings to the City during the
operation and maintenance of these sites by effectively scheduling the work required consecutively and in a cost
effective and timely manner.
Terms and Conditions
If services to be provided under this proposal require the agents, employees, or contractors of AECOM to enter onto
the Project site, Client shall provide right -of -access to the site to AECOM, its employees, agents, and contractors, to
conduct the planned field observations or services. The services described in this proposal will be provided on a time -
and -material basis. AECOM will not exceed the above estimate without your authorization and approval. The
services provided will be performed in accordance with the approved Fee schedule and with the conditions of the
2009 City of Oshkosh Negotiated General Conditions of Service, which are expressly incorporated into, and are an
integral part of, our contract for professional services.
