SUPPLEMENTARY INFORMATION:

Background: The EPA's Office of Radiation and Indoor Air (ORIA) requested the SAB to provide advice on a draft White Paper: Modifying EPA Radiation Risk Models Based on BEIR VII, dated August 2006. In 1994, EPA published a report, referred to as the “Blue Book,” which lays out EPA's methodology for quantitatively estimating radiogenic cancer risks: http://epa.gov/​radiation/​docs/​assessment/​402-r-93-076.pdf. A follow-on report made minor adjustments to the previous estimates and presented a partial analysis of the uncertainties in the numerical estimates: http://epa.gov/​radiation/​docs/​assessment/​402-r-99-003.pdf. Finally, the Agency published Federal Guidance Report 13: http://epa.gov/​radiation/​docs/​federal/​402-r-99-001.pdf which utilized the previously published cancer risk models, in conjunction with International Commission on Radiological Protection (ICRP) dosimetric models and U.S. usage patterns, to obtain cancer risk estimates for over 800 radionuclides, and for several exposure pathways updated at http://epa.gov/​radiation/​federal/​techdocs.htm#report13.

The National Research Council (NRC 2006) recently released Health Risks from Exposure to Low levels of Ionizing Radiation BEIR VII Phase 2 which primarily addresses cancer and genetic risks from low doses of low-LET radiation (BEIR VII) (NRC 2006 http://newton.nap.edu/​catalog/​11340.html#toc). In the EPA draft White Paper: Modifying EPA Radiation Risk Models Based on BEIR VII, the Agency proposes changes to EPA's methodology for estimating radiogenic cancers, based on the contents of BEIR VII. The Agency expects to adopt the models and methodology recommended in BEIR VII, but believes that certain modifications and expansions are desirable or necessary for EPA's purposes. EPA's ORIA staff is seeking this Advisory from the Agency's SAB Radiation Advisory Committee (RAC) to obtain advice on the application of BEIR VII and on issues relating to these modifications and expansions.

Pursuant to the Federal Advisory Committee Act (FACA), Public Law 92-463, the SAB Staff Office hereby gives notice of one public teleconference meeting and one face-to-face meeting of the SAB Radiation Advisory Committee (RAC). The SAB was established by 42 U.S.C. 4365 to provide independent scientific and technical advice, consultation, and recommendations to the EPA Administrator on the technical basis for Agency positions and regulations. The RAC will comply with the provisions of FACA and all appropriate SAB procedural policies.

The purpose of the teleconference is to: introduce the subject; determine if the review and background materials provided are adequate to respond to the charge questions directed to the SAB's RAC; receive public statements; and to discuss assignments to the RAC members in preparation for developing its draft advisory. The purpose of the meeting is to: receive presentations by the ORIA Staff; deliberate on the charge questions; receive public statements; and draft an advisory in response to the charge questions pertaining to the draft White Paper. Additionally, the RAC will receive briefings on ORIA activities, and will discuss plans for future activities.

Availability of Meeting Materials: A roster and biosketches of the RAC members, the meeting agenda, and the charge to the SAB's RAC will be posted on the SAB Web site at (http://www.epa.gov/​sab) prior to each meeting. Additional background information on this review include the draft White Paper (available at: http://epa.gov/​radiation/​news/​recentadditions.htm) and background materials, such as the BEIR VII document (available at http://newton.nap.edu/​catalog/​11340.html#toc). The RAC was initially briefed on the BEIR VII draft White Paper topic at its planning meeting of December 21, 2005 which was held at the National Air and Environmental Radiation Laboratory (NAERL) Laboratory in Montgomery, Alabama (see notification of a public teleconference and meeting 70 Fed. Reg. 69550, November 16, 2005). These notices, the charge to the RAC, and other supplemental information may be found at the SAB's Web site (http://www.sab.gov/​sab).

Persons who wish to obtain additional background materials on the draft White Start Printed Page 45546Paper may find them at the following Web site: http://epa.gov/​radiation/​news/​recentadditions.htm. Copies of the materials provided to the RAC, including the Agency's draft document entitled “White Paper: Modifying EPA Radiation Risk Models Based on BEIR VII,” dated August 2006, as well as briefing materials and other background materials pertinent to the activities announced in this notice may be requested from Dr. Mary E. Clark of the U.S. EPA, ORIA by telephone at (202) 343-9348, fax at (202) 243-2395, or e-mail at clark.marye@epa.gov.
