New Legal Agreement May
Get Cleanup Back on Track

Cedar Creek

Cedarburg, Wisconsin

November 2006

U.S. Environmental Protection Agency hopes a new legal agreement can restart
a pollution investigation in and around Cedar Creek next year. The study is
called a "remedial investigation" and will look at what kinds of substances are
present and in what quantities to determine whether they are harming human
health and the environment. This pollution study is a necessary step before an
actual cleanup can be done. The investigation stalled two years ago when one
of the companies legally responsible for the contamination, Amcast, twice went
through bankruptcy. EPA has received several inquiries about the status of the
Cedar Creek situation. This fact sheet will update what has been happening at
the site and what can be expected over the next year.

What's been done

Mercury Marine and Amcast, which operated factories near Cedar Creek, were
identified as responsible for the pollution in the area. Under legal agreements
worked out with EPA, Mercury Marine and Amcast sampled soil, water, creek
mud (sediment) and fish in 2003 and 2004. Mercury Marine also demolished its
Plant 2 in May 2005.

Amcast was in the process of finishing its part of the sampling when the
company filed for bankruptcy in November 2004. In November 2005, Amcast
agreed to complete the investigation but went bankrupt a second time and
did not finish the study. Meanwhile, Mercury Marine submitted its draft
investigation report for Cedar Creek in early 2005. In addition, Mercury Marine
submitted a separate study in early 2006 for the site of its former Plant 2. EPA
and state partner Wisconsin Department of Natural Resources are currently
reviewing the data from Mercury Marine's two studies.

The way the legal agreements with the two companies were set up caused the
investigation to stop when Amcast went bankrupt. That company was supposed
to give Mercury Marine its data that would then be combined into a document
called a "feasibility study." A feasibility study examines options for cleaning up
the contamination. Because Amcast's portion was never completed, a feasibility
study could not be done.

What's next

This spring EPA decided to break up the Cedar Creek site into separate parts
to get the project moving again. Mercury Marine's former Plant 2 site will
now have its own investigation report. EPA will amend the legal agreement in
order to free up Mercury Marine to move forward. The new agreement should
be completed by the end of this year or early 2007. If no more delays occur,
the investigation reports from Mercury Marine should be completed by next
summer. In the fall of 2007, the feasibility study outlining possible cleanup
options for the Plant 2 area and Cedar Creek should be complete. EPA is also
looking at ways to get Amcast involved again in the site.

Cedar Creek background

The Cedar Creek site consists of the company properties
of Mercury Marine, Amcast and a five-mile segment
of Cedar Creek from below the Ruck Pond Dam to the
Milwaukee River. This stretch of creek contains Columbia
Pond, Wire and Nail Pond and the former Hamilton Pond.
A dangerous chemical compound called poh chlorinated
biphenyls, or PCBs, contaminated the two industrial
locations, Cedar Creek and some private properties.

Boat maker Mercury Marine operated Plant 2 on St. John
Avenue from 1951 to 1982. Fluids containing PCBs leaked
from equipment and washed into storm sewers that flowed
to the creek. Plant 2 was demolished in 2005, but the
building site still contains PCBs. Amcast, an automotive
supplier, operated on Hamilton Road in Cedarburg. Its
plant also spilled PCBs that found their way to Cedar
Creek through storm sewers. One of the sewers emptied
into Hamilton Pond upstream of Green Bay Road. Flooding
washed out the Hamilton Dam and Pond in 1996, which
left behind several acres of mud flats containing PCBs.
