These summary sheets contain FC analyses on fish samples collected by MPCA from the Mississippi River. 3M did not participate in the design, sampling or analysis by MPCA, and hence, we do not have data and information beyond the summary sheets on matters such as sampling rationale(s), field sampling procedures, specific sample locations, analytical techniques, data quality objectives, Quality Assurance/Quality Control outcomes, etc. By way o f background, 3M has been conducting FC environmental monitoring in the vicinity o f its FC production facility in Cottage Grove, MN and several related disposal sites. This environmental monitoring has included sampling o f fish species from the Mississippi River, and 3M has provided these sampling data in prior submissions to the 8(e) docket. MPCA has engaged in its own FC sampling effort in this same vicinity as well as at various other locations throughout the state. 3M has been coordinating its FC environmental monitoring with MPCA. Through this coordination, 3M received the enclosed summary sheets on May 22, 2006 for MPCA's sampling o f various fish species at two general locations along the Mississippi River: (1) Pool 2, which is located between the Ford Lock and Dam and Hastings Lock and Dam and (2) Lake Pepin, which is a large natural impoundment o f the River with headwaters located about thirty miles downstream from the Hastings Lock and Dam. As noted above, 3M was not involved in MPCA's sampling (and hence cannot comment on the validity or representativeness o f the data) and does not believe that any o f these data taken alone or cumulatively meet the "substantial risk" reporting threshold. We nevertheless recognize the ongoing work by U.S. EPA to assess fluorochemical exposure pathways. Therefore, we are placing these results in the 8(e) docket as a supplement to previous submissions. If you have any questions, please do not hesitate to contact Gary Hohenstein at (651) 778-5150. Sincerely Katherine E.
