Five Year Review of Cleanup
at the Silver Bow Creek /
Butte Area Superfund Site
The Five-Year Review is a regular checkup on a Superfund site to
ensure that clean-up decisions continue to protect people and the
environment. The Five Year Review will be completed by
September 2010.
The U.S. Environmental Protection Agency (EPA) and Montana
Department of Environmental Quality (DEQ) are conducting a Five-
Year Review on the Silver Bow Creek / Butte Area site. The review
team is composed of several EPA Remedial Project Managers and
their consultants. The team will address the status of the cleanup and
the laws that apply to five sub-divisions (operable units) of the Super-
fund site. These are:
• Butte Mine Flooding (Berkeley Pit - remedy in place)
• Butte Priority Soils (mine waste, tailings and residential soil and
dust cleanup-ongoing)
• Rocker Timber Framing and Treatment Plant (soil and ground-
water cleanup completed)
• Warm Springs Ponds (three treatment ponds at Clark Fork River
headwaters completed)
Stream Side Tailings (From Colorado Tailings, west of Butte,
to Warm Springs Ponds - ongoing)
The review team members collect information about site clean-up
activities. They talk with people who have been working at the site
over the past five years, as well as local officials, to see if changes in
resources, working conditions, local policy or zoning might affect the
original clean-up plan. The team will visit the site to see if the clean-
up equipment is working properly. They may take new samples and
they will review records of activities during the past five years. EPA
will also be meeting with citizens individually or as a group about the
cleanup.
If you know anything about unusual site activities at or around the
site, such as trespassing or odors, or have other concerns, please let
the team know. You may submit written comments and mail them to:
Roger Hoogerheide, Remedial Project Manager
EPAMontana Office; 10 W. 15th St.; Helena, MT 59626
