The City of Minneapolis, Hennepin County and the Met Council all have Brownfields programs.  These programs provide grant money for property owners who would like to redevelop their property in the City of Minneapolis, but they suspect it may have environmental issues.  Of course the site needs to be cleaned correctly before any new development can occur.

If you have a property that might need some clean up, the government does have funds available but you must get your application in quickly.  New grants will be made February 2012, but in order to be considered for a grant in early 2012, you must complete the application within the next two weeks so that they have time to review it and make a decision.  The deadline is December 14, 2011.
