The NTP announced the RoC review process for the 12th RoC on April 16, 2007, in the Federal Register (72 FR 18999 available at http://ntp.niehs.nih.gov/go/15208). An expert panel meeting is being convened on July 21-22, 2008, to review styrene for possible listing in the 12th RoC. The draft background document for styrene will be available on the RoC Web site on May 22, 2008, in printed text from the RoC Office (see ADDRESSES above). Persons can register free-of-charge with the NTP listserv to receive notification when draft RoC background documents for other candidate substances for the 12th RoC are made available on the RoC Web site (http://ntp.niehs.nih.gov/go/231).
Styrene is a very important monomer used worldwide in the production of polymers, which are incorporated into products such as rubber, plastic, insulation, fiberglass, pipes, automobile parts, food containers, and carpet backing. Most of these products contain both free styrene monomer and styrene polymerized in long chains (polystyrene). Sources of exposure to the general public include inhalation of indoor and outdoor ambient air, smoking, and ingestion of foods. Occupational exposure occurs mainly in the reinforced plastics, styrene-butadiene rubber, and styrene monomer and polymer industries.
Preliminary Agenda, Availability of Meeting Topics and Registration
Preliminary agenda topics include:
- Oral public comments on styrene.
- Peer review of the draft background document on styrene.
- Recommendation for listing status for styrene in the 12th RoC.
The meeting is schedule for July 21-22, 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).

Request for Comments
The NTP invites both written and oral public comments on the draft background document on styrene. All written comments received will be posted on the RoC website 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, e-mail, and sponsoring organization, if any) and send them to Dr. Lunn (see ADDRESSES above) for receipt by July 07, 2008. Time will be set-aside at the expert panel meeting for the presentation of oral public comments. Seven minutes will be available for each speaker (one speaker per organization).

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 chemicals. 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.Start Signature
