In the report, the Science Advisory Board offers a new assessment of environmental problems, based on the comparative risks posed by these problems. The Board further calls for innovative, integrated policies to effectively and efficiently reduce the most serious risks. With its emphasis on preventing pollution before it becomes a problem, on market incentives, on educating, on cooperation among EPA, other agencies, and other sectors of society, reducing risk is already guiding much of what the authors do here at EPA. The advisory committees give sound advice and provides fresh, independent perspectives on business matters at EPA. The five new advisory committees for the year are: The Acid Rain Advisory Committee; The Clean Air Act Advisory Committee; The Environmental Financial Advisory Board; The Lead Acid Battery Recycling Negotiated Rulemaking Advisory Committee; and The Reformulated Gasoline Rule and Oxygenated Gasoline -- Marketable Oxygen Credit Program Guidelines and Labeling Regulations Negotiated Rulemaking Advisory Committee.
