Primary Response Goals

1.  In general, any spilled oil product should be diverted and kept in the main channel of the Mississippi River. Then, if possible, the oil should be diverted with boom and collection should take place on the Minnesota shore

2.  Three areas are designated as critical mussel habitat by the US FWS. Consult with resource managers to keep spilled product or response actions from affecting the substrate in these areas.

3.  Keeping product out of the three closed areas is a top priority in any spill event. Due to seasonal high waterfowl use, deflection and exclusion booming of multiple opening and channels should be prioritized as a response tactic


To further explain the techniques used above, refer to the image below labeled 619a – French Island in the GRP. The strategy for this location is to boom shore to shore to protect the fish overwintering area.



If a spill occurs, it is essential to notify federal, state, and local authorities within 24-hours of the spill.
