We are enclosing compact disc (CD No. 6) containing a number of studies, as more fully described. The CD No. 6 includes studies previously submitted since January 2002. All of the studies have already been submitted to the AR-226 Docket as paper copies. On the enclosed CD, you will find an index to the toxicology and environmental studies, and copies of those studies. As in our past submissions, we have organized the studies by chemical, and within the sections for each chemical, by end point or type of study. The CD is for read-only purposes and is not to be modified. 3M will maintain the original CD copy of the documents. As indicated in the note prefacing the CD, 3M's original CD will control in the event of any discrepancy. We have submitted copies of this CD to the agencies of Belgium, the UK, Sweden, Japan and Canada. We will continue to provide information as it becomes available. We look forward to our continuing dialogue with the agency. Please feel free to contact me with any questions. Enc.
