The National Toxicology Program (NTP) on Wednesday announced the availability of the draft background document for glass wool fibers by April 9, 2009, on the RoC website (http://ntp.niehs.nih.gov/go/29679).

The NTP is inviting the submission of public comments on the draft background document for glass wool fibers. An expert panel will meet on June 9-10, 2009, at the Sheraton Chapel Hill Hotel, One Europa Drive, Chapel Hill, N.C., to peer review the draft background document for glass wool fibers and, once completed, make a recommendation regarding the listing status (i.e., known to be a human carcinogen, reasonably anticipated to be a human carcinogen, or not to list) for glass wool fibers or categories of glass wool fibers (i.e. "certain" glass wool fibers) in the 12th RoC.

The RoC expert panel meeting is open to the public with time scheduled for oral public comments. Attendance is limited only by the available meeting room space. Following the expert panel meeting and completion of the expert panel report, the NTP will post the final background document and the expert panel peer review report on the RoC website.

The deadline to submit written comments is May 22, 2009, and the deadline for pre- registration to attend the meeting and/or provide oral comments at the meeting is June 1, 2009.
