SIGNATURE,
ITEM SUMMARY:
To date, all environmental contamination intended to be removed from the 14 acres of City-owned land known as
the West Washington Street Project has been completed, but for three areas adjacent to structures on 119 W.
Washington Street that are awaiting completion of the salt dome on Hawthorne Land and their eventual demolition.
The last remaining area includes the former gas station at 139 W. Washington Street, which closed in early July
2019. This project involves pulling the tanks, demolition of the existing structures, pavement and curbing, site
investigation and devising a remediation program to be approved by the IEPA; the attached scope of work
provides more details. There is currently $600,000 included in the City Council’s 2019 approved budget for this
project.
While staff intended for this project to begin in August 2019, the City requested and eventually was allocated via
Representative Karina Villa $600,000 to offset the costs of this project as approved by the State in its Capital Bill.
However, no money may be spent prior to an Agreement being approved between the City and the State, so the
project cannot yet start. Staff is working with representatives of the DuPage Mayor and Managers Conference to
better understand the process for securing an Agreement, but answers from the State are not yet forthcoming.
So, this project will not occur until 2020, but staff is requesting that the City Council approve this Change Order so
it is ready for when the grant documentation is ready for completion. Staff will again include this money in the
2020 Budget.
ACTIONS PROPOSED:
Staff recommends approval of Resolution No. 19-R-0048, which authorizes Patrick Engineering to continue
working on the West Washington Street Remediation Project, for an amount not to exceed $575,000.
COMMITTEE RECOMMENDATION:
This item didn’t go to Committee because it was already approved in the 2019 Budget, and the final stages of this
Project must be completed.

Mr. Michael L. Guttman
City Administrator
City of West Chicago
475 Main Street
West Chicago, Illinois 60185
Subject: Change Order 005 for Remediation of Former Gas Station
West Washington Street Redevelopment Site
West Chicago, Illinois
Reference: Patrick Project Number 21653.008
Dear Mr. Guttman:
Patrick Engineering Inc. (Patrick) is pleased to submit this change order request to the City of West Chicago
(the City) to provide environmental consulting and site remediation services for a portion of the West
Washington Street Redevelopment Site, specifically the former gas station located at 139 West
Washington Street. The scope of services outlined in this proposal is consistent with the recommended
scope items in the attached Economic Feasibility Study of Remedial Options (Patrick Engineering, February
2, 2017). This proposal contains Patrick’s anticipated project schedule and fees to complete the
referenced scope of services.
PROJECT UNDERSTANDING
The City currently owns approximately 14 acres of property on the north side of Washington Street in
West Chicago, Illinois (Site). The City plans to develop this property over the next several years into a new
municipal center. Tentative plans for the new municipal center include a new City Hall, public space, and
other mixed-use developments. In early 2017, Patrick was contracted by the City to complete remediation
activities (including permitting and reporting tasks) associated with obtaining a No Further Remediation
(NFR) Letter from the Illinois Environmental Protection Agency (Illinois EPA) under its Site Remediation
Program regulatory framework.
Since that time, Patrick has completed a supplemental site investigation, prepared preliminary reports for
submittal to the Illinois EPA, and completed the remediation of all radionuclide compounds associated
with the West Washington Redevelopment Site. The overall remediation project is ongoing, and is
expected to reach into 2020 after the existing salt dome is removed and the underlying soils are accessible
for remediation.
One area which was specifically excluded from Patrick’s original scope of work, however, was the active
gas station located at 139 West Washington Street. While the City owned this property, it maintained a
lease to a local operator of a gasoline filling station. The City allowed the gas station to continue operation
until June 1, 2019, and no investigation or remediation activities could take place on that parcel until that

time. Now that the lease has ended, the City has access to this additional property and Patrick can begin
its work in remediating this parcel as well.
This proposal outlines the Scope of Work that Patrick proposes to complete in order to complete
remediation of the former gas station site, and estimates the costs associated with the completion of
these tasks. Because a subsurface site investigation of the gas station site has been impossible while the
station was operating, remedial costs outlined in this change order proposal are estimated based upon
Patrick’s past experience with such sites, and the available data from subsurface soils directly adjacent to
the relevant property. These costs have been estimated conservatively, but may need to be adjusted as
additional site data becomes available.
SCOPE OF WORK
Task 1 — Site Investigation
As noted above, the 139 West Washington site was excluded from the site investigation activities that
took place in 2017 and early 2018. The first task associated with the remediation of the former gas station
will be a limited soil investigation. Up to 15 soil samples will be collected at various locations and depths
across the parcel, consistent with the methodology described in the existing Sampling and Analysis Plan
(SAP) that has already been reviewed by the Illinois EPA. These samples will be analyzed for the
compounds noted in the SAP, and relevant to obtaining an NFR Letter for the West Washington
Development Site.
The results of this investigation will be used to develop a proposed Remedial Action Plan with respect to
the gas station site, for submittal to the Illinois EPA under the Site Remediation Program regulatory
framework.
Task 2 — Tank Removal
Consistent with state and federal rules governing underground storage tanks, the two, 10,000-gallon
underground gasoline storage tanks at 139 West Washington will be excavated and removed. This
removal will involve the following subtasks:
Obtaining the Office of the State Fire Marshal (OSFM) Tank Removal Permit;
Notifying public utilities through the Illinois One-call System (JULIE) to locate underground utilities in
accordance with Illinois State law;
3. Providing a private utility locator to perform private underground utility locates in the area of the
excavation;
4. Mobilizing the necessary labor and equipment to the Site;
5. Construction of a temporary 6’-high chain link security fence;
6. Opening the tanks, pumping, and disposing of remaining tank contents (this proposal assumes the tanks
will be largely empty except for some minor liquid in the bottom of the tanks);
7. Purging the tanks of flammable vapors;
8. Uncovering and removing any existing concrete slabs over the tanks;
9. Hauling concrete offsite for disposal as a recyclable material;
10. Excavating and removing two (2) 10,000 gallon USTs;
11. Opening and cleaning the tank interiors;
12. Removing associated product and vent piping;

===== PDF PAGE 44 =====

The City of West Chicago
Remediation of 139 West Washington Street Page 3 of 5
June 7, 2019
13. Hauling and properly disposing of the tanks and piping to an approved disposal facility;
14. Furnishing a certificate of tank destruction;
15. Collecting up to a total of six (6) samples of soil from the excavation (one from each excavation sidewall and
two from the excavation bottom);
16. Delivering samples to an accredited environmental testing laboratory for analysis;
17. Backfilling the tank excavation with CA-1 aggregate to a depth of 18” below grade, covered by a non-woven
geotextile or filter fabric, covered by 12” of CA-6 aggregated, topped by 6” of topsoil, certified as clean with
accompanying analytical sampling results.
18. Managing the removal contractor, documenting the removal efforts, coordinating with City of West Chicago
personnel; and
19. Documenting proper removal and disposal of the tanks to OSFM.
A representative of the OSFM will be present onsite during the tank excavation. If this representative
determines that a tank is leaking, or has leaked, gasoline into the environment, he/she will create an
incident number for the site, which will be reported to the Illinois Leaking Underground Storage Tank
(LUST) division of the Illinois EPA. Should this occur (and it is reasonable to assume that this could
happen), Patrick will petition the Illinois EPA to fold the resulting LUST remediation effort, which would
be required by law, into the Site Remediation Program regulatory framework. It is very likely that the
Illinois EPA will grant such a request, especially given the ongoing remediation efforts at the West
Washington site.
Task 3 — Demolition of Existing Structure
The former gas station site included a small gas station building on the north side of the property. This
building along with all will be removed as part of the tank removal effort. This removal will involve the
following subtasks:
1. Submitting Notification of Demolition to Illinois EPA;
2. Securing DuPage County Demolition Permit;
Performing asbestos inspection for notification of demolition (this proposal assumes that no asbestos will
be found);
Demolition of one-story building to grade, including light poles, sign, pumps, and wooden fence;
Complete removal of concrete building pad, footings, pavement, and curbs inside property line;
Off-site disposal of all demolition debris; and
Utility capping and/or disconnect fees.
w
“son Ss
This demolition does not include the removal of concrete approaches, sidewalks or curbs within the City right-of-
way.
Task 4 — Site Remediation
Without knowing the results of the site investigation, or seeing the open excavation during the tank
removals, it is impossible to know the extent to which the former gas station site will require remediation.
However, based upon our experience with hundreds of similar tank removals, we are able to provide a
relatively conservative cost estimate for this task that has a good chance of covering most contingencies.

Remediation of 139 West Washington Street Page 4 of 5
June 7, 2019
The Illinois EPA handles the chemical components of gasoline in a different manner than most of the other
site contaminants found in the West Washington Redevelopment Site. While many of the other
contaminants can be capped safely with a shallow layer of clean soil, the volatile nature of many gasoline
components requires a thicker cap (up to 10 feet), depending on the concentrations found. Accordingly,
a worst-case scenario for the remediation of these soils would be the excavation and removal of soils to
a depth of 10’, over a fairly wide area of the site. However, there are several alternative remediation
scenarios that could be implemented by Patrick, depending on the conditions found:
1. No significant contamination of soils at the 139 West Washington site is found, or the
contamination that is found is not volatile, and can be easily capped. This is fairly unlikely; most
gas station sites, especially those that have been active for many years, exhibit some degree of
contamination, usually with volatile components, such as benzene.
2. Contamination is found at depth at the site, but over a fairly limited areal extent. In this case, it
may make sense to install one or more simple wells in the affected areas, and connect them to a
simple air blower (< 1 hP). By injecting oxygen into the affected subsurface areas, the naturally
occurring aerobic bacteria in the soils will be stimulated to biodegrade the volatile gasoline
components into non-toxic components. This form of remediation is called bioventing, and can
take on the order of months to years to achieve success. Other remedial activities at the West
Washington Development Site won’t likely occur until 2020, so bioventing might be a reasonable
approach to take, at least until active remediation begins the following year.
3. Contamination is found at depth over a wide areal extent. In this case, targeted excavation and
off-site disposal used in combination with an onsite capping strategy is likely to be the most cost-
effective option.
It is possible that some combination of all three of these strategies might prove appropriate. For the
purposes of this proposal, we have assumed a fairly conservative scenario (largely consisting of targeted
excavation) where 4,000 cubic yards of soil are either treated or removed from the site.
Documentation and reporting of the remediation of the gas station soils is included in this task, and will
be coordinated with the overall reporting effort associated with the wider West Washington
Redevelopment Site remediation that will continue into 2020.
FEE
Patrick proposes to provide the scope of services outlined herein on a time-and-materials basis for an
estimated budget shown below. The estimated costs include Patrick labor, Project Management and
reporting, subcontractor costs (including disposal of impacted soils and importing clean backfill), travel
and other direct costs required to complete the scope of services outlined herein. Remediation and
construction costs are based on hard quotations provided by specialty contractors and vendors
(laboratories, transportation firms, excavators, landfills, etc.), and on Patrick’s past experience in
remediating similar sites.
Patrick believes the estimated costs included below are conservative and they include contingencies for
unknowns, changes and unforeseen conditions. However, there are some conditions which may be

===== PDF PAGE 46 =====

The City of West Chicago
Remediation of 139 West Washington Street Page 5 of 5

beyond Patrick’s control (sampling results, EPA comments and/or approvals, weather, site conditions,
etc.) which may affect overall costs.
If during the course of the work, Patrick determines that the project costs are likely to exceed this estimate
for any reason(s), the reason(s) will be immediately communicated to the City, and appropriate budget
amendments can be negotiated at that time. Patrick will not incur costs that exceed those shown below
without the express authorization of the City.
Task 1: Site Investigation S$ 25,000
Task 2: Storage Tank Removals (Includes IEPA/LUST Coordination) $ 125,000
Task 3: Demolition and Removal of Structures, Pavement, & Curbing S$ 45,000
Task 4: Remediation of 139 Washington Soils (4,000 cubic yards) $ 380,000
Estimated Total: S$ 575,000
AGREEMENT AND AUTHORIZATION
All work outlined in this proposal will be performed in accordance with the Terms and Conditions of the
existing agreement between Patrick and the City. A Project Change Order is included as an attachment
to this proposal. If you would like Patrick to perform the services outlined above, please sign the Change
Order, and return to the undersigned at Patrick. Receipt of the executed documents will be considered a
Notice to Proceed. This proposal is considered valid for 30 days after the date of this letter proposal.
We appreciate the opportunity to provide you with this proposal. If you have any questions, please feel
free to contact us at your earliest convenience. We continue to appreciate the opportunities that the City
has provided to Patrick to be of service, and we are committed to the successful implementation of this
important project.
