During the five-year review, EPA and
NDEQ inspect the site and study site
information to make sure the remedy
continues to be protective. We
encourage the community to tell us about
site conditions or concerns you may have.

At the end of the review, a final report will
be prepared and will be available in the
site information repositories. The goal is
to complete the review and report in
September, 2003.
