Subject: RE: taconite petitions for review

Alan and Matt,

As we discussed during our telephone conference last week, Cliffs shares EPA’s interest in supporting the rulemaking record for

the upcoming proposed rule to implement the BART FIP settlement. Cliffs is currently able to confirm that my August 8 th letter

(No. 1 on your list below and attached) can be used without redaction or limitation in the rulemaking record. Cliffs withdraws

any claim of confidential business information for the information in that August 8 th letter, but retains the CBI claim for the

attachments to that letter. The other documents on your list (#2

‐ #6) are the subject of ongoing consideration and discussions

with the Cliffs facilities and the various vendors (Metso, Coen, FCT) regarding proprietary information to determine the

necessary scope of any continuing CBI claim. We hope to complete those discussions soon so we can forward documents

suitable for use in the public record (e.g., with appropriate redactions) or provide substitute documents with updated

information as we discussed.

We appreciate your patience as we work through this process,

Sincerely,
