The Incident Response Unit (IRU) Priority List includes sites that are associated with the storage, application, transportation, handling and/or distribution of agricultural chemicals. These sites fall into two groupings: 1) sites with known agricultural chemical incidents (as defined in Minnesota Statute Chapter 18D.01, subd. 6) and 2) sites that do not have a documented incident at this time. The sites that do not have a documented incident, and some of the sites that do, are also designated by the letters “AB” in the Location column which is an abbreviation for “abandoned”. Abandoned sites are former/no longer operating agricultural chemical facility sites. It should be noted that the IRU staff has not confirmed that all sites that do not have the “AB” designation are still in operation. At the sites with known incidents, at least one soil or ground-water sample was collected and analyzed, and the analytical results indicate that the sample(s) contain(s) agricultural chemicals.
In 2004/05 the MDA received a grant from the U. S. Environmental Protection Agency to identify and geo-locate former agricultural chemical sites in Minnesota. More than 500 former sites were located and evaluated. Some of these sites did not require additional follow up. Other sites had already been placed on existing priority lists within the IRU, awaiting future work. The remaining 135 sites were determined to require follow up. The IRU staff has utilized state contractors to collect samples at over twenty (20) of these former or abandoned sites to date. All of the land owners and all existing responsible parties that could be located have been notified that their former agricultural chemical site is included in the IRU Priority List. The IRU staff also continues to identify agricultural chemical facilities as they are decommissioned/abandoned, and invites the owners/operators to enter these sites in the AgVIC program. Abandoned sites not entered into the AgVIC program are added to the Priority List.
