SUPPLEMENTARY INFORMATION:

Background

The RoC is a congressionally mandated, science-based, public health report that identifies agents, substances, mixtures, or exposures (collectively called “substances”) in our environment that pose a cancer hazard for people in the United States. The NTP prepares the RoC on behalf of the Secretary of Health and Human Services.

The NTP follows an established, four-part process for preparation of the RoC (http://ntp.niehs.nih.gov/​go/​rocprocess). A RoC monograph is prepared for each candidate substance selected for review for the RoC. Trichloroethylene was selected as a candidate substances following solicitation of public comment, review by the NTP Board of Scientific Counselors on June 21-22, 2012, and approved by the NTP Director (http://ntp.niehs.nih.gov/​go/​9741). A draft RoC monograph consists of (1) a cancer evaluation component that reviews all information that may bear on a listing decision, assesses its quality and sufficiency for reaching a listing decision, applies the RoC listing criteria to the relevant scientific information, and recommends a listing status for the candidate substance in the RoC and (2) a substance profile that contains the NTP's preliminary listing recommendation and a summary of the scientific evidence considered key to reaching that recommendation. This meeting is planned for peer review of the draft RoC Monograph on TCE.

Trichloroethylene (CASRN 79-01-6) is a halogenated alkene used primarily in the past as a degreaser for metal parts and more currently as an intermediate for hydrofluorocarbon (e.g., refrigerant) production. It is a common drinking water contaminant and has also been found in contaminated air and soil, and is an ingredient in many consumer products (e.g., aerosols or degreasers for hobbies, crafts and home and automobile maintenance). It is currently listed as reasonably anticipated to be a human carcinogen in the 12th RoC. Additional information about the review of TCE for the RoC is available at http://ntp.niehs.nih.gov/​go/​37899.

Meeting and Registration

This meeting is open to the public with time set aside for oral public comment. The public may attend the meeting at NIEHS, where attendance is limited only by the space available, or view the webcast. Registration is required to view the webcast; the URL for the webcast will be provided in the email confirming registration. Individuals who plan to provide oral comments (see below) are encouraged to register online at the meeting Web site (http://ntp.niehs.nih.gov/​go/​38853) by August 5, 2014, to facilitate planning for the meeting.

The preliminary agenda and draft monograph should be posted on the NTP Web site (http://ntp.niehs.nih.gov/​go/​38853) by June 30, 2014. Additional information will be posted when available or may be requested in hardcopy, see FOR FURTHER INFORMATION CONTACT. Following the meeting, a report of the peer review will be prepared and made available on the NTP Web site. Registered attendees are encouraged to access the meeting Web page to stay abreast of the most current information regarding the meeting.

Visitor and security information is available at http://www.niehs.nih.gov/​about/​visiting/​index.cfm. Individuals with disabilities who need accommodation to participate in this event should contact Ms. Danica Andrews at phone: [phone] or email: [e-mail]. TTY users should contact the Federal TTY Relay Service at [phone]. Requests should be made at least five business days in advance of the event.

Request for Comments

The NTP invites written and oral public comments on the draft monograph. The deadline for submission of written comments is July 30, 2014, to enable review by the peer-review panel and NTP staff prior to the meeting. Registration to provide oral comments is by August 5, 2014, at http://ntp.niehs.nih.gov/​go/​38853. Public comments and any other correspondence on the draft monographs should be sent to the FOR FURTHER INFORMATION CONTACT. Persons submitting written comments should include their name, affiliation, mailing address, phone, email, and sponsoring organization (if any) with the document. Written comments received in response to this notice will be posted on the NTP Web site, and the submitter will be identified by name, affiliation, and/or sponsoring organization.

Public comment at this meeting is welcome, with time set aside for the presentation of oral comments on the draft monograph. In addition to in-person oral comments at the meeting at the NIEHS, public comments can be presented by teleconference line. There will be 50 lines for this call; availability will be on a first-come, first-served basis. The lines will be open from 8:30 a.m. until adjournment on August 12, 2014, and oral comments will be received only during the formal public comment period indicated on the preliminary agenda. Each organization (sponsoring organization or affiliation) is allowed one time slot. At least 7 minutes will be allotted to each speaker, and if time permits, may be extended to 10 minutes at the discretion of the chair.

Persons wishing to make an oral presentation are asked to register online at http://ntp.niehs.nih.gov/​go/​38853 by August 5, 2014, and if possible, to send a copy of their slides and/or statement or talking points at that time. Written statements can supplement and may expand the oral presentation. Registration for in-person oral comments will also be available at the meeting, although time allowed for presentation by on-site registrants may be less than that for registered speakers and will be determined by the number of speakers who register on-site.

Background Information on the RoC

Published biennially, each edition of the RoC is cumulative and consists of substances newly reviewed in addition to those listed in previous editions. The 12th RoC, the latest edition, was published on June 10, 2011 (available at http://ntp.niehs.nih.gov/​go/​roc12). The 13th RoC is under development. For each listed substance, the RoC contains a substance profile, which provides information on: Cancer studies that support the listing—including those in humans, animals, and studies on possible mechanisms of action—information about potential sources of exposure to humans, and current Federal regulations to limit exposures.

Background Information on NTP Peer-Review Panels

NTP panels are technical, scientific advisory bodies established on an “as needed” basis to provide independent scientific peer review and advise the NTP on agents of public health concern, new/revised toxicological test methods, or other issues. These panels help ensure transparent, unbiased, and scientifically rigorous input to the program for its use in making credible decisions about human hazard, setting research and testing priorities, and providing information to regulatory agencies about alternative methods for toxicity screening. The NTP welcomes nominations of scientific experts for upcoming panels. Scientists interested in serving on an NTP panel should provide a current curriculum vita to the FOR FURTHER INFORMATION CONTACT. The authority for NTP panels is provided by 42 U.S.C. 217a; section 222 of the Public Health Service (PHS) Act, as amended. The panel is governed by the Federal Advisory Committee Act, as amended (5 U.S.C. Appendix 2), which sets forth standards for the formation and use of advisory committees.
