RE: Approve Professional Services Agreement with AECOM Technical Services, Inc.
(AECOM) for Knapp Street Quarries, Kienast-Paulus Quarries, and Timmerman
Landfill for Operations, Monitoring, and Maintenance Support during 2022
Calendar Year ($139,500)
BACKGROUND
The Department of Public Works has utilized AECOM Technical Services, Inc. (AECOM) for
various environmental engineering needs at the Quarry Park Landfill located on Knapp Street
since 1979, at the Timmerman Landfill since 1978, and at the Kienast-Paulus Quarries since 2015.
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.
Based on the deterioration of the well head vaults, a replacement plan for the well head vaults
has been recommended. AECOM’s budget includes an estimated subcontractor budget to
replace approximately five (5) of the seventeen (17) most-damaged well heads.
In 2019, AECOM submitted a plan modification for the Timmerman Landfill to the WDNR
proposing to reduce the sampling frequency of the gas probes from quarterly to semiannually
due to low methane concentrations being detected; remove volatile organic compound sampling
from monitoring wells MW-6 and MW-8; and remove sampling for pH, temperature, specific
conductance, and turbidity from the environmental monitoring requirements for monitoring
wells MW-9 and MW-10. The plan modification was approved by the WDNR on October 8, 2019.
In 2015, the City of Oshkosh (City) initiated a landfill gas monitoring and site investigation at the
Kienast-Paulus Quarries. Due to the results of the monitoring investigation, continued landfill
gas monitoring, acquisition of property with residential structures on or near the former landfill
footprint, and the installation of an active landfill gas collection system were recommended by
AECOM. During 2018 and 2019, the City acquired the following properties: 905 West 17th
Avenue, 875 - 885 West 17th Avenue, 859 West 17th Avenue, and Outlot 1 of the parcel address of

1732 Knapp Street. In 2018, AECOM was retained to design a landfill gas system and submit the
design for approval to the WDNR. The design was approved by the WDNR on November 15,
2019. The landfill gas system was installed in the winter of 2019 and the spring of 2020 and started
operation in May 2020.
ANALYSIS
This agreement will cover the required operations, monitoring, and maintenance at all three (3)
former landfills for calendar year 2021. 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 $139,500. The cost for these gas monitoring services will be allocated to the
operating budget (Account 02120470-6401/Sanitation Division-Contractual Services). This
contract amount represents an increase in fee from 2021 of $19,200. This is due to the addition of
the services related to the well head replacements at the Knapp Street Quarries Landfill.
RECOMMENDATIONS
Chapter 12 of the Municipal Code of the City of Oshkosh 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 that the Common Council approve the award of this professional
services agreement.
Approved:
Mark A. Rohloff
