Abstract: The US Environmental Protection Agency recently revised the regulations in the clean air act regarding air pollution, setting new standards for ozone and for particulate matter. we discuss a general approach to the setting of standards from the perspective of statisticians and other environmental scientists, and illustrate some of the issues with ozone data from California's central valley.

2. Statistics and Mandated Science

Van Belle, Gerald,   University of Washington

Address: Department of Environmental Health Box 357234 University of Washington Seattle, WA 98195-7234

Phone: 206-543-6991



Abstract: Mandated science operates at the intersection of science and policy, both which are embedded in values. mandated science defines, directs and uses the results of science in establishing and evaluating policy. statisticians and statistical methods play a key role in mandated science. this paper illustrates some key characteristics of statistical methods used in mandated science. these results are then applied to three examples of mandated science: lead in soils, air pollution and clean up of the nations nuclear weapons complex. the statistical issues in mandated science include problems of measurement, exposure, association, the use of large data bases not specifically established for scientific purposes, and linkages of data bases using statistical rather than mechanistic models.

3. Statistics in Environmental Decision Making: They Really Do Count!

Nussbaum, Barry D.,   EPA

Address: Center for Environmental Information and Statistics Mail Code 2163 U.S. Environmental Protection Agency 401 M Street, SW Washington, D.C. 20460

Phone: (202) 260-1493

Fax: 202-260-4968


Abstract: Despite the cynicism, statistics are used in the decisions made on environmental policy, regulations, and enforcement actions. However, it is frequently the effectiveness of the presentation of the statistics, rather than the raw statistics that make the difference. several general guidelines are explored; and then three specific examples in which the author was personally involved are discussed. one ended up in a regulation, one in court, and one on the desk of the President of the United States.
