The Office of Risk Assessment and Cost-Benefit Analysis (ORACBA) was established by the Federal Crop Insurance Reform and Department of Agriculture Reorganization Act of 1994 (P.L. 103-354, H.R.4271,
Section 304). ORACBA began operation on April 15, 1995, in USDA's Office of the Chief Economist.
The Office of Risk Assessment and Cost-Benefit Analysis's (ORACBA) primary role is to ensure that major regulations proposed by USDA are based on sound scientific and economic analysis.
COMPARING HUMAN HEALTH RISK VALUES: AN ANALYSIS OF SCIENCE POLICY CHOICES
Elizabeth Holman, Environmental Protection Agency

Rm. 4433, South Building

Environmental and public health organizations including the World Health Organization (WHO) and the U.S. Environmental Protection Agency (USEPA) develop human health risk values (HHRV) that set ‘safe’ levels of exposure to non-carcinogens. For chronic exposure, HHRVs go by multiple organization-specific names including reference doses (RfDs) and acceptable daily intake (ADI). Here, we systematically evaluate both the HHRV and the choices made in deriving an HHRV for a given chemical by different organizations, specifically those from the U.S. Environmental Protection Agency, Health Canada, RIVM (Netherlands), and the U.S. Agency for Toxic Substances and Disease Registry. Overall, across the 96 unique chemicals and 171 2-way organizational comparisons, the HHRV agreed approximately 26% of the time. In the first part of our study, a qualitative method for identifying the primary factors influencing these HHRV differences was developed, using arrays of HHRVs across organizations for the same chemical. The primary factors identified were disagreement on the critical study and differential application of the total UF across organizations. Of the cases where the total UF was the primary factor influencing HHRV disagreement, the database UF had the largest impact. In the second part of our study, we further evaluated these 171 organizational comparisons, developing a quantitative method for identifying the factors to which HHRV agreement (that is, when both organizations considering the same data set the identical HHRV values) is most sensitive. To conduct this analysis, a Bayesian Belief Network was built using expert judgment, including the specific science policy choices analysis made in the context of setting an HHRV.

Measuring the Social Costs of Carbon: The Promise and Pitfalls of Using the SCC to Justify Regulation
Co-sponsored by the DC Bar, Environment, Energy, and Natural Resources Section
March 31, 12:00 – 1:30 p.m., D.C. Bar Conference Center, 1101 K Street, Washington DC
The Social Cost of Carbon tool assesses the economic costs of greenhouse gas emissions. Our panel of experts will offer a primer on the tool and debate the advantages and shortcomings of relying on it as a factor in agency decision-making.
Speakers: Richard Ayres, co-founder of the Natural Resources Defense Council, managing partner, Ayres Law Group LLC; Dr. Kevin Dayaratna, Heritage Foundation; Dr. Laurie Johnson, Natural Resources Defense Council; Patrick Traylor, partner, Hogan Lovells; Jessica Olson, Ayres Law Group LLP (moderator)

SOCIETY FOR BENEFIT COST ANALYSIS – ANNUAL MEETING
FOOD AND WATER ISSUES
Eliza Mojduszka is making a presentation on “Consumer Valuation of Organic Egg Characteristics and its Implications for Public Policy” at the Society for Benefit Cost Analysis Annual meeting on March 20 in the Food and Water Issues panel. Linda Abbott is serving as the discussant for the Food and Water Issues panel.
The increasing emphasis on risk-based decision making and the increasingly global nature of the food supply have resulted in the use of risk analysis to systematically address food safety issues worldwide. This has created a need to educate food safety and other public health professionals about the principles of food safety risk analysis and the tools and techniques required to apply this approach.
