Discharge of PFCs from 3M Cottage Grove Plant at SD002 (Coolin~ Water)
3M does not monitor the cooling water discharge SD002 for PFCs. The only data known
available for PFC concentrations in the SD002 cooling water discharge is from the "MPCA Investigation of PFC Contamination in Minnesota Phase I Study" (Dr. Fardin
Oliaei Report to Senate Environment Committee of February 2006) which found the
following PFC concentrations at SD002, for samples collected at the 3M Cottage Grove

Future PFC Monitoring at SD001 and SD002
On February 9, 2007, MPCA staff sent a letter to 3M which requires that 3M immediately begin monitoring 14 PFC compounds at both the SD001 and SD002 discharges on a monthly basis, to begin in February 2007. The expanded analysis will include PFBA, as well as 8 other PFC compounds in addition to the 5 currently analyzed. The MPCA believes that more complete analytical data is needed to be able to assess the impacts of the 3M PFC discharge, including discharge of PFCs from the SD002 cooling water discharge. The MPCA is also currently in the process of developing discharge criteria for PFOS and PFOA, expected to be completed within the next few months.
