MEMORANDUM
March 29, 2004
TO:
The Honorable Mayor and City Council Members
FROM:
Michael C. Van Milligen, City Manager
SUBJECT: Terracon Contract for Professional Services
Petroleum Remediation in the Port of Dubuque
Economic Development Director Bill Baum is recommending the selection of Terracon
as the environmental design and remediation consultant for petroleum cleanup in the
Port of Dubuque.
The City has previously received a $200,000 grant from the U.S. E.P.A. and has
recently been notified that it will receive an additional $142,655 grant from the State of
Iowa to assist in the cleanup of the petroleum contamination at the former Molo Oil site.
The estimated cleanup costs at the time of grant application were $570,000 for a three-
year time period.
A Selection Committee interviewed four firms. Each firm proposed a slightly different
approach to the remediation. EPA provided technical assistance to this selection
process through Kansas State University, who evaluated the proposals and suggested
questions to be answered by the consultants. They also provided additional information
on the technologies being proposed.
Terracon was the unanimous choice ofthe committee. They presented an aggressive
approach that was under budget and with a timeframe shorter than the anticipated
remediation period. They also will provide on-site monitoring out of their Dubuque
office. The proposed cleanup will involve vacuuming the free product petroleum that is
floating on the water table and then injecting hydrogen peroxide into both water and soil
to cause chemical oxidation that dissolves the contamination while also accelerating
bioremediation through the additional oxygen being introduced. They estimate
$545,000 to complete the project.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

Terracon Contract for Professional Services
Petroleum Remediation in the Port of Dubuque
SUBJECT:
Introduction
The purpose of this memorandum is to request City Council concurrence with the
selection of Terracon as the environmental design and remediation consultant for
petroleum cleanup in the Port of Dubuque.
Background
The City has previously received a $200,000 grant from the U.S. E.P.A. and has
recently been notified that it will receive an additional $142,655 grant from the State of
Iowa to assist in the cleanup of the petroleum contamination at the former Molo Oil site.
The estimated cleanup costs at the time of grant application were $570,000 for a 3-year
time period.
On February 24, 2004, a Selection Committee, including myself, Pam Myhre, Rich
Russell, Mary Rose Corrigan, Jonathan Brown, Kyle Kritz and Deron Muerhing,
interviewed four firms to carry out the remediation design and petroleum cleanup
activities. Terracon (Davenport & Dubuque), Preston Engineering (Bettendorf),
BarkerLemar (Des Moines) and URS (Chicago & Des Moines) met with the committee
to elaborate on their proposed remediation plan and to answer questions. Each firm
proposed a slightly different approach to the remediation and the committee. EPA
provided technical assistance to this selection process through Kansas State University
who evaluated the proposals and suggested questions to be answered by the
consultants. They also provided additional information on the technologies being
proposed.
Discussion
Terracon was the unanimous choice of the committee. They presented an aggressive
approach that was under budget and with a timeframe shorter than the anticipated
remediation period. They also will provide on-site monitoring out of their Dubuque
office. The proposed cleanup will involve vacuuming the free product petroleum that is
floating on the water table and then injecting hydrogen peroxide into both water and soil
to cause chemical oxidation that dissolves the contamination while also accelerating
bioremediation through the additional oxygen being introduced. They estimate
$545,000 to complete the project. The City has budgeted for the remediation expense
in a 2004 CIP for Riverfront Leasehold Improvements.
The City's environmental attorney, Jane McAllister of the Ahlers Law Firm, has
reviewed and approved the contract language.
Recommendation
I recommend that the City Council concur in the selection of Terracon to provide the
environmental design and remediation services for the cleanup of petroleum
contamination in the Port of Dubuque and that the City Council adopt the attached
resolution authorizing the City Manager to negotiate and execute a contract for
professional services.
Action Step
The action step is for the City Council to adopt the attached resolution.
