Proposal for Environmental Consulting Services Related to the Proposed Site Development of the city of
Oshkosh Parking Lot Located at 0 State Street,Oshkosh,Wisconsin
Dear Mr.Davis:
AECOM Technical Services, Inc.(AECOM)appreciates the opportunity to submit this proposal to the City of
Oshkosh(City)for professional environmental engineering services related to pursuing a Voluntary Party
Liability Exemption(VPLE)for the City Parking Lot located at 0 State Street,Oshkosh,Wisconsin(Subject
Property). We understand that the City is considering a property transaction associated with parking lot
and obtaining a VPLE prior to the property transaction that will benefit the planned redevelopment and
assist with the property transfer. AECOM was previously retained to complete a Phase I Due Diligence
Environmental Site Assessment(ESA)and Phase II ESA at this site.
The Phase I ESA report identified the Subject Property as an irregular-shaped property utilized as an asphalt-
paved city parking lot. Historical research performed as part of the Phase I ESA indicated the site and
surrounding properties were incorporated into the City of Oshkosh since at least 1890 and owned by the City
since around 1969. Sanborn Fire Insurance Maps(Sanborn)used in the Phase I ESA indicated that the
Subject Property was formerly occupied by a paint shop,bicycle shop,an auto repair shop and residences.
The Phase I ESA identified the following RECs:
• A 1949 Sanborn map indicated a 120-gallon gasoline UST was located under the sidewalk adjacent to
State Street and Lot 3.The lack of information pertaining to the UST's status and/or potential adverse
impacts to the Subject Property is considered a REC.
• A 1949 Sanborn map indicated a 150-gallon gasoline UST was located under the Subject
Property.The lack of information pertaining to the UST's status and/or potential adverse impacts to
the Subject Property is considered a REC.
• Historical land use as an auto repair shop prior to the transfer of the property to the City of Oshkosh in
1968 is consider a REC due to lack of information pertaining to the historic use as a auto repair shop.
The Phase II ESA indicated that there are Polynuclear Aromatic Hydrocarbons(PAH)and Volatile Organic
Compounds(VOC)impacts in the soil and groundwater, particularly in the central area of the parking lot
located in the former auto repair facility. These laboratory testing results indicate a release to the
subsurface environment has occurred. Some of the detected PAHs and VOCs are above State of
Wisconsin soil and groundwater standards. In accordance with State of Wisconsin hazardous substances
spill law,and with permission from the City,the results of the investigation were forwarded to the Wisconsin
Department of Natural Resources(WDNR), On October 5, 2016 the State of Wisconsin sent a letter
outlining the City's responsibilities for addressing the contamination. The following actions are required by
the WDNR to be performed by the City unless an exception is granted by the WDNR.

* Hire an environmental consultant within 30 days of receipt of the responsibility letter.
^ Submit a work plan for completing the site investigation within 60 day of the responsibility letter.
° Initiate the site investigation within 90 days of submitting the site investigation work plan.
* Submit a Site Investigation Report to the WDNR 60 days after receipt of the laboratory data.
* Submit a Remedial Actions Option report 60 days after submitting the Site Investigation Report.
On November 3, 2016,The City emailed Kevin Mc Night of the WDNR informing him that AECOM was in the
process of being retained to address the issue and requested a 90 day extension on submittal of the Work
Plan. On November 9, 2015 at 8:55 AM,the City received an email approval response from Kevin Mc Night,
VVUNR.
A subsequent meeting with City Staff and the Developer indicated that a VPLE will be pursued and if
granted would promote site redevelopment and initiate a property transfer.
This proposal presents our understanding of this project,site knowledge,current and previous VPLE
experience onseveral City ofOshkosh sites, This proposal outlines our recommended scope ofwork and
estimated fee for submitting a request for a VPLE for the site development and full filling the WDNR
requirements related tothe subsurface release requirements.
Project t Inderstanding
The City of Oshkosh is considering promoting site redevelopment by applying for a site VPLE. The VPLEis
avital part ofBrownfield Redevelopment, AEC0K4has successfully assisted the City inobtaining several

AECOM
R.iSkE FlroVkie (Dn-,'!)'ite C01[1StI1ctbnDOCUnO8rtador")
AECOM will provide trained environmental field staff to document the construction of the environmental
components of the project.These components include Soil Management,Contaminated Groundwater
Management, Underground Utilities,Vapor Mitigation(if required)and Site Capping.
Soi| Menagement
We propose to have an AECOM representative on site to observe and identify the excavation of areas
containing impacted soil requiring disposal. This will beaccomplished through visual and olfactory
observations (sheen,petroleum product,stained soils and petroleum odors)and field screening of the soils
excavated for obvious signs nfcontamination, The AECOMfield staff will use uphoto ionization detector
(PID)to field screen the excavated soils. PID field screening readings of 15 instrument units(equivalent to
ppm)or higher will be considered contaminated and hauled to Waste Management's Valley Trail Facility,
Nonpetroleurn impacted fill soils/solid waste that can be reused for site fill will be segregated and reused.
Nonpetroleum/solvent impacted fill soils/solid waste deemed not usable as backfill material will be hauled
tnthe Valley Trail Facility for disposal.
The contaminated soil disposed of in a landfill requires manifesting,which needs a signature by an
authorized representative of the City. To expedite the processing of the landfill profile acceptance
applications and soil removal activities for this project,the City will delegate authority to AECOM to sign the
waste profile application and transportation manifests on behalf of(acting as an agent for)the City. It is
understood that the City will remain the responsible party for all final decisions regarding management and
disposal of contaminated materials encountered during this project. By authorizing this proposal,the City
will also be authorizing Paul F.Timm and his designees of AECOM to act as the authorized agent for the
City for completing the waste profile and transportation manifests,as needed,to dispose the
contaminated soil under this contract.
CnntaminetE�,d GroundvvatorManegenoent
We anticipate that the impacted groundwater removed from the project excavations will be collected and
pumped into the Oshkosh sanitary sewer system under the conditions that will be provided in the
temporary discharge permit obtained by AECOM. AECOM proposes to be on site periodically to make sure
the contractor is discharging groundwater in accordance with the anticipated temporary discharge permit.
UndergroundUd|ities
We anticipate utilities running through the solid waste fill and petroleum impacted areas could create
routes of less resistance for gases and liquids to migrate into and from the site. In compliance with
anticipated permit requirements, utilities entering and leaving the project area limits will have a trench plug.
Trench plugs will be placed where the utility line enters a structure. AECOM proposes to document the
location,construction and size ofeach trench plug,
Vapor Mitigation(C)ptiona|)
A vapor barrier comprised of an impermeable liner and passive venting system will likely not be required
below structure slabs and foundations to prevent the migration of moisture and vapors produced by the
solid waste fill and/or petroleum impacts left in place. If required,this vapor barrier will likely consist of a
polyethylene(PE)geomembrane sealed at the seams,providing a continuous barrier between the subsoil
and floor slab. The passive venting system could be comprised of perforated piping between the building
foundations,floor slab,and subsoil. Uthis system iurequired,AECOMproposes todocument this barrier's
installation.

Site ("I"apping
AEC{)K4will document the site capping components. These components include the paved parking lot,
lined storm water bio filters/pave drain, 16 Inches of soil covering fabric warning barrier under landscape
areas and building base slab.
Please note based on recent VPLE documentation experience,we anticipate additional field and project
management time will berequired todocument construction activities.
