Unpermitted Dump Sites

The list of Unpermitted Dump Sites was created in the 1980's and
was originally called the Open Dump Inventory (ODI). Sites
maintained in this list were later referred to as Outstate Dump
Inventory (ODI) and Metro Dump Inventory (MDI) sites. Because
these sites are no longer open the name has been changed to
Unpermitted Dump Sites and contains dump sites for the entire
state. Included in the list are abandoned dumps, demolition
sites, tree disposal sites, industrial dumps and other dumps.
Most of these sites existed prior to the creation of the MPCA in
1967, and detailed information about them is not generally
available. When these sites are investigated and found to
present a risk to human health or the environment, they are
moved into the appropriate cleanup program. For more
