Report on Carcinogens Webinar on Pentachlorophenol; Notice of 
Public Webinar and Registration Information

SUMMARY: The National Toxicology Program (NTP) announces a public 
webinar, ``Human cancer studies on exposure to pentachlorophenol (PCP): 
Differentiating potential cancer effects of PCP exposure from effects 
due to occupational co-exposures or PCP contaminants.'' The Office of 
the Report on Carcinogens (ORoC), Division of the NTP (DNTP), National 
Institute of Environmental Health Sciences (NIEHS) will hold the 
webinar using Adobe[supreg] ConnectTM, and the public can 
register to attend.

DATES: 
    Webinar: April 11, 2013, 12:30 p.m. to approximately 5:00 p.m. 
Eastern Daylight Time (EDT).
    Pre-Registration for Webinar: March 8, 2013 to April 8, 2013.

ADDRESSES:
    Webinar Web page: The agenda, speaker abstracts, registration, and 
other meeting materials are at https://ntp.niehs.nih.gov/go/pcpwebinar.

FOR FURTHER INFORMATION CONTACT: Dr. Ruth M. Lunn, Director, ORoC, 
DNTP, NIEHS, P.O. Box 12233, MD K2-14, Research Triangle Park, NC 
27709. Phone: (919) 316-4637; Fax: (301) 480-2970, Email: 
lunn@niehs.nih.gov. Hand Delivery/Courier: 530 Davis Drive, Room 2138, 
Morrisville, NC 27560.

SUPPLEMENTARY INFORMATION: 
    Background: The Report on Carcinogens (RoC) is a congressionally 
mandated, science-based, public health report that identifies agents, 
substances, mixtures, or exposures (collectively called ``substances'') 
in our environment that are cancer hazards for people living in the 
United States. The NTP prepares the RoC on behalf of the Secretary of 
Health and Human Services following an established, four-part process 
(https://ntp.niehs.nih.gov/go/rocprocess).
    PCP, including its sodium salt, is a chlorinated aromatic compound 
that is used primarily as a wood preservative in the United States. It 
was selected as a candidate substance following solicitation of public 
comment and review by the NTP Board of Scientific Counselors on June 
21-22, 2012 (https://ntp.niehs.nih.gov/go/9741) (for more information on 
the status of NTP review of PCP see https://ntp.niehs.nih.gov/go/37897).
    The objective of the webinar is to provide scientific input to the 
ORoC on issues related to its approach for evaluating the epidemiologic 
studies on exposure to PCP and not to receive recommendations from 
invited speakers or the public on whether or not PCP should be listed 
in the RoC. The webinar will consist of (1) four presentations, each of 
which will be followed by a short question and answer period specific 
for the presentation, and (2) a discussion session across 
presentations. The goals of the individual presentations are (1) to 
identify occupational co-exposures and PCP components or contaminants 
in human epidemiologic studies of exposure to PCP, (2) to identify 
which co-exposures should be considered as potential confounders, and 
(3) to discuss the methods used in the epidemiologic studies to 
evaluate confounding.
    Webinar and Registration: The webinar is scheduled for April 11, 
2013, from 12:30 to approximately 5 p.m. e.d.t. The webinar may end 
early if the presentations and general discussion period are finished. 
The public may register for the webinar beginning March 8, 2013, 
through April 8, 2013, at https://ntp.niehs.nih.gov/go/pcpwebinar. There 
will be 50 connections available on a first-come, first-served basis 
for registrants. Registrants will receive instructions by email to 
access the webinar (via Adobe[supreg] Connect\TM\) on or before April 
9, 2013.
    The preliminary agenda, list of speakers, and abstracts of the 
presentations should be posted on the NTP Web site (https://ntp.niehs.nih.gov/go/pcpwebinar) by March 26, 2013. Registrants are 
encouraged to access the webinar Web page to stay abreast of the most 
current information regarding this event. Any updates will be posted to 
the Web site.
    Public Participation: Time will be set aside following each 
presentation and during the general discussion period after the talks 
are finished for the public to ask questions or make brief remarks. 
Instructions for participating in the meeting via Adobe[supreg] 
Connect\TM\ will be included in the information for accessing the 
webinar. Individuals with disabilities who need accommodation to 
participate in this event should contact Dr. Lunn. TTY users should 
contact the Federal TTY Relay Service at 800-877-8339. Requests should 
be made at least five business days in advance of the event.
    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 
https://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.
