RE: Budget Increase Request for Continued Environmental Consulting Services
Mercury Release and Underground Storage Tank Assistance
City of Dubuque Water Pollution Control Plant
Dear Mr. Sampson Brown:
MWH Americas, Inc. (MWH) appreciates the opportunity to submit this proposal to provide
continuing environmental engineering assistance to the City of Dubuque, lowa (City) relating to
the mercury spill and the former petroleum product underground storage tank (UST) at the
City's water pollution control plant (WPCP) site. Because of the number of samples collected
and submitted for rush analysis during remediation of the south trickling filter, and the additional
time required on site by MWH personnel, the previously authorized budget has been exhausted.
This proposal is intended to include 1) final oversight, verification sampling and analysis, and
reporting activities related to remediation of mercury impacted trickling filter media and
structures; 2) assistance to the City regarding potential cost allocation for remediation costs
between historic mercury releases and the recent spills; and 3) general consulting assistance
associated with the closure reporting for the former on -site UST and other tasks as requested
by the City. More detailed descriptions of the proposed activities for these three general tasks
are outlined below.
Task 1— Mercury Remedlation Sampling and Reporting
Activities to be conducted under this task are intended to complete the sampling and analysis
and final reporting for the mercury remediation in the trickling filter basins. Activities to be
conducted by MWH include the following:
• Prepare the final report summarizing the response action activities, field screening
and analytical results, and disposal of materials from the trickling filters and
surrounding soil. Provide the draft report to the City and others, as directed, for
review. Revise the report per the comments and submit a final report to the lowa
Department of Natural Resources (IDNR).

• Continue to coordinate with the remediation contractor, North Shore Environmental
Construction, Inc., (North Shore) as needed. MWH will relay outstanding analytical
results to North Shore and forward any additional correspondence from the IDNR.
■ Provide additional regulatory assistance for coordinating final disposal of trickling
filter media or other waste related to the remediation.
• Process final laboratory invoices.
• Process final travel and equipment costs.
■ Protect management for MWH on -site activities.
No additional on -site time is anticipated; however, MWH will also provide support and
interaction with the IDNR, as requested by the City.
Task 11— Cost Allocation Assistance
Under this task, MWH will participate in a meeting with the City and other site contractors to
develop a basis for a proposed allocation of costs related to the investigation and cleanup of
mercury in and around the trickling filters. MWH understands the purpose of the meeting is to
identify costs related to historic spills versus those resulting from the September 2010 spill. It is
assumed the meeting will be held for one day in Dubuque, Iowa and will be attended by Randy
Kroneman of MWH's Des Moines, Iowa office. MWH will also provide support to the City, as
requested to review the report being prepared by Exponent, Inc.; and identify specific waste
streams generated during the remedial activities.
Task 111 — UST and General Assistance
MWH will review the Tier 2 Site Cleanup Report (Tier 2 SCR) report to be prepared and
submitted to the IDNR by Seneca, Inc. (Seneca), for the leaking UST formerly located northeast
of the WPCP administration building, and provide comments to the City. Based on the
analytical results of sidewall soil samples collected by Seneca during the over excavation of
impacted soil, the site failed to meet the IDNR Tier 1 screening levels; therefore, a Tier 2
evaluation is required. MWH will also provide comments on any other related activities
proposed by Seneca or requested by the IDNR MWH understands an extension for submitting
the Tier 2 report was requested and granted by the IDNR. The Tier 2 report is due January 1,
2012. The proposed activities will be conducted under the supervision of an Iowa- Certlfed
Groundwater Professional; and in compliance with requirements of Chapter 135 of the Iowa
Administrative Code (IAC), and associated IDNR guidance documents.
Under this task, MWH will also provide general consulting services for the WCPC as requested
by the City. These activities are assumed to include collection of up to six sediment samples
from drain traps in the WPCP on -site laboratory. The samples will be submitted for analysis of
total mercury and the results provided to the City. Other activities may include

recommendations for disposal or management of materials generated or discovered during the
WPCP renovation.
