SUBJECT CATEGORY: National Toxicology Program (NTP); Report on Carcinogens (RoC); Availability of the Draft Background Document for Cobalt-Tungsten Carbide Powders and Hard Metals; Request for Comments on the Draft Background Document; Announcement of the Cobalt-Tungsten Carbide Powders and Hard Metals Expert Panel Meeting
DATES: The expert panel meeting for cobalt-tungsten carbide powders and hard metals will be held on December 910, 2008. The draft background document for cobalttungsten carbide powders and hard metals will be available for public comment by October 10, 2008. The deadline to submit written comments is November 24, 2008, and the deadline for pre registration to attend the meeting and/or to provide oral comments at the meeting is December 1, 2008.
DOCUMENT SUMMARY: The NTP announces the availability of the draft background document for cobalttungsten carbide powders and hard metals by October 10, 2008 on the RoC Web site (http://ntp.niehs.nih.gov/go/29679) or in printed text from the RoC (see ADDRESSES below). The NTP invites the submission of public comments on the draft background document for cobalttungsten carbide powders and hard metals. The expert panel will meet on December 910, 2008, at the Sheraton Chapel Hill Hotel, One Europa Drive, Chapel Hill, NC 27514 to peer review the draft background document for cobalttungsten carbide powders and hard metals 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 cobalttungsten carbide powders and hard metals in the 12th Edition of the RoC (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 expertpanel peer review report on the RoC Web site.
SUMMARY: Draft Background Document for Cobalt-Tungsten Carbide Powders and Hard Metals; Expert Panel Meeting,
SUPPLEMENTAL INFORMATION
BackgroundThe NTP announced the RoC review process for the 12th RoC on April 16, 2007 in the Federal Register (72FR18999 available at http:// ntp.niehs.nih.gov/go/15208). An expert panel meeting is being convened on December 910, 2008, to review cobalttungsten carbide powders and hard metals for possible listing in the 12th RoC. The draft background document for cobalttungsten carbide hard metals and powders will be available on the RoC Web site by October 10, 2008 or in printed text from the RoC Office (see ADDRESSES above). Persons can register free ofcharge with the NTP listserv to receive notification when draft RoC background documents for candidate substances for the 12th RoC are made available on the RoC Web site (http://ntp.niehs.nih.gov/go/231).
Cobalttungsten carbide hard metals are composites of carbides
(including tungsten carbide alone or in combination with small amounts
of other carbides) with a metallic cobalt binder, pressed into a
compact, solid form at high temperatures by a process known as
``sintering.'' Cobalttungsten carbide hard metals are used primarily
in cutting tools. Cobalttungsten carbide hard metals are manufactured
and used in the United States. Occupational exposure to cobalttungsten
carbide hardmetal particles can occur during hardmetal production,
recycling of hardmetal products, and grinding and sharpening of hard metal tools.
Preliminary Agenda, Request for Comments, and Registration
Preliminary agenda topics include:
The meeting is scheduled for December 910, 2008, from 8:30 a.m. to adjournment each day. A copy of the preliminary agenda, expert panel roster, and any additional information, when available, will be posted on the RoC Web site or may be requested from the Director of the RoC Office (see ADDRESSES above). Individuals who plan to attend the meeting are encouraged to register online by December 1, 2008, to facilitate planning for the meeting.
Request for Comments
The NTP invites both written and oral public comments on the draft
background document on cobalttungsten carbide powders and hard metals.
All written comments received will be posted on the RoC Web site prior
to the meeting and distributed to the expert panel and RoC staff for
their consideration in the peer review of the draft background document
and/or preparation for the expert panel meeting. Persons submitting
written comments are asked to include their name and contact
information (affiliation, mailing address, telephone and facsimile
numbers, email, and sponsoring organization, if any) and send them to
Dr. Lunn (see ADDRESSES above) for receipt by November 24, 2008. Time

Background Information on the RoC
The RoC is a congressionally mandated document [Section 301(b)(4) of the Public Health Services Act, 42 U.S.C. 241(b)(4)], that identifies and discusses agents, substances, mixtures, or exposure circumstances (collectively referred to as ``substances'') that may pose a hazard to human health by virtue of their carcinogenicity. Substances are listed in the report as either known or reasonably anticipated to be human carcinogens. The NTP prepares the RoC on behalf of the Secretary of Health and Human Services. Information about the RoC and the nomination process can be obtained from its homepage (http://ntp.niehs.nih.gov/go/roc) or by contacting Dr. Lunn (see FOR FURTHER INFORMATION CONTACT above). The NTP follows a formal, multi step process for review and evaluation of selected substances. The formal evaluation process is available on the RoC Web site (http:// ntp.niehs.nih.gov/go/15208) or in printed copy from the RoC Office.
