Ladies and Gentlemen:
After forwarding to you our letter of October 20, 2005, on the referenced topic, we received from the 3M Company corrections to certain data that we had attached at Exhibit C to that letter. The revised data received from 3M is attached hereto at Exhibit A. In addition, we found two typographical errors in Chart A included in our October 20, 2005, letter. The "212.40"

In addition, the "29.64/36.80" ppb total PFCs referenced on the 4th line of Chart A on Page 6 of the letter should read "39.08/36.80" ppb total PFCs. Please include these corrected data in USEPA Administrative Record 226 and OPPT-2003-0012. Thank you.

INTERROGATORY NO. 3:
Identify each hum an drinking w ater supply in M innesota or W isconsin where any PFCs have ever been detected, specifying the dates o f each such detection for each such water supply, the level and/or concentration o f each PFC detected, and the identity o f the entity(s) who conducted and/or arranged for the sam pling and analysis. ANSWER:
See 3M 's General O bjections and specific objections in its Answers to Plaintiffs' Discovery Requests, which are incorporated in this response by reference. Subject to and without w aiving its general objections and the objections to this interrogatory stated below, 3M states as follows:

3M presented data in a table on page 19 for M arch 2005 and on page 20 for April 2005 Oakdale M unicipal W ell sampling results. The values listed as Exygen results are actually the MDH results for March Thus, the April results on page 20 should be deleted. There are no April 2005 results from either MDH o r Exygen.
