Pursuant to the Federal Advisory Committee Act, Public Law 92-463, notice is hereby given that the EPA SAB will hold a public teleconference to review two draft SAB documents. The SAB was established by 42 U.S.C. 4365 to provide independent scientific and technical advice to the Administrator on the technical basis for Agency positions and regulations. The SAB is a Federal Advisory Committee chartered under the Federal Advisory Committee Act (FACA), as amended, 5 U.S.C., App. The SAB will comply with the provisions of FACA and all appropriate SAB Staff Office procedural policies.

Background: The purpose of the public teleconference is to conduct a quality review of two draft SAB documents. These documents are the: (a) Science Advisory Board's Homeland Security Advisory Committee Consultation on the EPA's Emergency Consequence Assessment Tool and Incident-based Microbial Risk Assessment Framework, and (b) Advisory on the Agency Draft White Paper Entitled Modifying EPA Radiation Risk Models Based on Bier VII. In reviewing draft reports, the SAB considers whether: (i) The original charge questions to the SAB review panel were adequately addressed in the draft report, (ii) the draft report is clear and logical; and (iii) the conclusions drawn, or recommendations made in the draft report, are supported by the body of the report.

(a) The EPA National Homeland Security Research Center (NHSRC) requested that the SAB provide technical advice on its Emergency Consequence Assessment Tool (ECAT) and its preliminary incident-based Microbial Risk Assessment (MRA) Framework (see 72 FR 20538 of April 25, 2007) which are being developed by the NHSRC. ECAT is an interactive online risk assessment and management software tool to provide health advisors, and other emergency response officials, with rapid access to critical information during an environmental emergency or training exercise. ECAT is designed to assess and provide site-specific numeric estimates of health risks for selected chemical, biological and radiological threat agents; and identify appropriate response actions to mitigate these risks. Additionally, NHRSC asked the SAB for advice on its White Paper describing issues important to the development of a decision framework for assessing health risks and developing clean up levels associated with a decontamination response following exposure to microbial agents. Additional information about the SAB consultation on these two topics is available on the SAB Web Site at:​sab/​panels/​hsacadhoc.html.

(b) EPA's Office of Radiation and Indoor Air (ORIA) asked the SAB to provide advice on a draft White Paper: Modifying EPA Radiation Risk Models Based on BEIR VII, dated August 2006 (see 71 FR 45545 of August 9, 2006; 71 Start Printed Page 46058FR 62950 of October 26, 2006; and 72 FR 8379 of February 26, 2007). EPA's White Paper describes an updated methodology for quantifying estimated cancer risks from environmental exposures to radionuclides. The EPA's methodology is based on the National Research Council (NRC 2006) 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). Additional information about the SAB's review of EPA's White Paper, and the development of the SAB draft report, can be found on the Web at:​sab/​panels/​rac_​adv_​white_​paper_​rad_​risk_​models.htm.
