Dear Mr. Potter:
This letter is in follow-up to our December 3, 2009, letter to you, regarding the
unauthorized discharge of dredged or fill material into approximately 4,252 square feet of
wetlands adjacent to Otsego Creek which is a tributary to the Mississippi River. The project site
is in NW 1/4, Sec. 6, T. 120N., R 23W., Wright County, Minnesota.
After our telephone conversation on December 10, 2009, we have decided to grant you a
time. extension for completion of your after -the -fact permit application. Please send your
completed application form and signed tolling agreement to Andy Beaudet by January 31, 2010.
If we do not receive a permit application to retain the illegal fill, along with the tolling
agreement, by that date, we will consider referring the case to the U.S. Department of Justice or
the Environmental Protection Agency (EPA) for enforcement.
If you have any questions, please contact Andy Beaudet in our St. Paul office at (651)
290-5642. In any correspondence or inquiries, please refer to the file number shown above.
Sincerely,
Tamara E. Cameron
