Proposal for KienmatQPaulus Quarries Landfill Gas Extraction System Design and Bidding Services
Dear Mr. Rabe,
AECOK8Technical Services, Inc. (AECOK8) has prepared this proposal for design and bidding services for
construction of the landfill gas collection system at the former Kienast and Paulus Quarries. This proposal provides
the project background, proposed scope of work, and estimated costs for the tasks proposed.
Pro.ecA 111"Mckground
AECOM conducted an extensive site investigation over an area of approximately 8 acres, identifying extents of the
buried municipal waste,the presence of landfill gas, quantity of landfill gas,the possibility of landfill gas migration,
quarry limits and determining the historical disturbed soil areas related to the former quarry operations and
subsequent filling.
An electromagnetic (EM) geophysical survey was performed to aid in delineation of the lateral extent of the quarries in
which construction debris and municipal waste were disposed.
Acombination of test pits and soil borings were used to determine the waste limits and characterize the waste
materials. The results from the geophysical survey and from historical documents(aerial photographs and historic
City drawings)were used kodetermine test pit and soil boring locations.
In general,the fill material within the Kienast Quarry consisted of a majority of municipal solid waste mixed with soil.
There was osmall amount ofconcrete and asphalt pieces and wood debris observed. The fill material within the �
Paulus Quarry generally consisted of concrete, asphalt and wood demolition debris mixed with soil.
AECOM has performed monitoring for landfill gases in site monitoring wells since September 2015. Three separate
vapor extraction pilot tests were performed to investigate the potential for landfill gas recovery within the limits of
waste atthe Kionaotand Paulus Quarries.
The results of the extensive site investigations revealed the limits of waste, landfill gas (LFG) is being generated
and/or trapped inthe waste, and itiafeasible Voextract the gas byapplying ovacuum within the waste.
Selecting the appropriate LFG extraction system depends on the site-specific conditions and the project objectives. In
this case,the quarries were unlined prior towaste filling,the groundwater io relatively shallow(approximately 13 to
18 feet below ground surface), and the primary concern is'migration of LFG through the soil and rock beyond the
landfill. The conditions and objective are very similar as those encountered at the Knapp Street Quarries. The
system AECOM designed for Knapp Street Quarries has effectively controlled the LFG. Asimilar design inproposed
for the LFGextraction system s$Kionastand Paulus Quarries.
The proposed system includes a perimeter collection header connected at intervals to segments of horizontal
collection pipes with valves toallow adjustments of the vacuum. Each pipe segment will bmabout 1OOfeet long from �
the end of the perforated pipe\othe control valve. This approach allows for better gas system operation control oo
vacuum can be adjusted to the areas needing the most LFG control.The horizontal stone trench along the site
perimeter will be a porous medium for available LFG to be collected by the gas system.

Ablower will provide vacuum for the system. The blower could boeither aseparate unit, ovcould beconnected bothe
Knapp Street Quarry Landfill blower. These details will beevaluated further indesign. Aflare ioburn excess LHG is
not expected to be necessary for the Kienast and Paulus Quarry Landfills, but this will be verified during design.
Condensate is expected to be returned to the landfill using a layout of the header system that automatically drains
back through the perforated piping network. This type ofcondensate return has been effective atthe Knapp Street
Quarry site. If necessary, an additional condensate knockout structure would be employed.
Excess waste ielikely 0obegenerated during the system construction. Likely disposal cf the excess material will bo
at the Waste Management, Valley Trail Recycling and Disposal Facility in Berlin,Wisconsin. The waste disposal has
been approved by Waste Management at a negotiated tipping fee of$33 per ton,which includes a$13 per ton
Wisconsin Generator Tax. The typical tipping fee this type nfwaste io$38per ton. Another disposal option that may
significantly reduce the landfill tipping and transportation costs is to regrade the site and incorporate excess waste
and recap the site. This option will likely require City ownership of the site.
AECOM staff has extensive experience with LFG issues in the immediate proximity to the Kienast and Paulus
Quarries. The Knapp Street Quarries are former quarries filled with similar waste.We have been involved with the
monitoring,site investigation, designing, documenting the construction of several types of LFG venting since
approximately 1976. The LFG collection and venting system installed in 2010 has accomplished the design goals of
controlling the LFG. Based on this local experience along with AECOM's extensive design and operation of LFG
systems across the United States we propose the following scope of services which are based on the Technical
Memorandum dated January 27.2O17provided for this site.
Sc�ope of Services
The following scope of services for Kienast and Paulus Quarries Landfill Gas Extraction System is proposed.
Sun/eV
A topographic survey of the two former quarries is required to complete the LFG system design. Survey points ona
(maximum) 1 00-foot grid will be taken to prepare a topographic map having a 1-foot contour interval for use in design
and preparation nfconstruction drawings. Identifying and mapping the location ofall underground and above ground
utilities, and critical existing structures iorequired. VVeanticipate that the City will self-perform these services and
provide a completed site map including all line work in AUTOCAD format. AECOM will provide a map with proposed
survey limits and data necessary 8ocomplete the site map.
Project ManagBrD8ff)L �11[ldPUb|icOUtr8aCh
AECOMstaff will coordinate the design ofthe project with stake holders. VVoanticipate assisting with apublic
outreach program led byCity staff. AECOK4will prepare information memorandums and poster boards for uptotwo
(2) public meetings. In addition,we anticipate up to 10 meetings with stake holders during the design phase of the
project. Typically there will bmseveral discussions with VVNDRstaff during design. Afinal LFGdesign submittal will
boprepared and sent tothe VVDNRfor review and approval. VVoanticipate uptutwo clarifications and follow upof
additional information that VVDNHmay request.

1. Obtain a LFG sample from an existing gas monitoring well within the limits of Kienast Quarry. The sample is to
boanalyzed for benzene and vinyl chloride. AECDK8will compare the results toWisconsin Department of
Natural Resources(WDNR) air emission code requirements to determine if the LFG can be exhausted without
use ofeflare. |f the test results are within allowable WDNR emission levels,AECOM will submit a letter to
VVDNRrequesting anexemption from the Administrative Code. The intent iatueliminate the need for aflare.
2. Coordinate with WDNR to determine the expectations of the WDNR for this project.
3. Before completing the design, coordinate with the City of Oshkosh on current plans for land acquisitions at
Kienao\and Paulus Quarries and adjoining properties. The ownership of the site and surrounding sites may

impact the final design parameters of the system. Land ownership will impact system design, permitting with
WDNR,waste disposal costs and final site grading.
4. Design an active LFG extraction system to collect gas from the perimeter of each of the two landfills. The blower
system will be located near the two landfills or the extraction system could be combined with the Knapp Street
extraction system and the existing blower may require an upgrade. This will be determined during design.
5. The LFG extraction system design will consist of the following components:
a. Horizontal gas collection pipes, located in waste, above groundwater, and extending around the inside of
the perimeter of each landfill.
b. The LFG will be collected using a gas header connected to the collection pipes at regular intervals and
terminating at the blower station.
C. The blower station will include instrumentation and controls to allow for it to run part-time on an adjusted
timer and automated features for automatic restart and shut down.
d. Condensate management consisting of draining through collection pipes back into the waste.
e. The LFG will be vented, if no flare is required.
6. Coordinate with the power utility to provide electrical service to the proposed blower station. The service
customer will be the City of Oshkosh. Support of City personnel will be needed in arranging for the service. If
the existing blower station will be used,electrical power needs will be re-evaluated.
7. Provide for electrical design of the blower system. In the event that the system will utilize the existing blower at
Knapp Street,the electrical and controls work will still be needed to coordinate the new system with the existing
infrastructure.
8. Prepare the following drawings:
a. Title and Index
b. Existing Conditions
C. Landfill Gas Extraction System
d. Spoils Relocation Plan
e. Erosion Control Plan
f. Piping Profiles
g. Piping and Vault Details
h. Blower Station Details
L Erosion Control Details
j. Electrical, Instrumentation and Control
9. Prepare and submit a Permit Plan Modification to WDNR for approval of the proposed installation at the Site.
Fees associated with WDNR review of reports, designs, or submittals are not included in the fee estimate for this
project and will be paid by the City.
10. Prepare technical specifications so that the equipment materials, workmanship, and installations are provided in
accordance with design requirements and expectations.
11. Coordinate preparation of bid documents with the City of Oshkosh. Submit pre-bid plans and specifications to
City for review and comment. One set of documents and an electronic copy will be submitted.
12. Prepare a Water Resources Application for Project Permits(WRAPP)to obtain construction site storm water
permit coverage from WDNR. Submit to WDNR for review and approval. WDNR permit fees will be paid directly
by the City. The permit will follow the requirements for a Construction Site Storm Water Runoff General Permit
