Assistant Professor Bonnie Keeler co-authored a national study, the “Report on the Repeal of the Clean Water Rule and its Replacement with the Navigable Waters Protection Rule to Define Waters of the United States,” released by the External Environmental Economics Advisory Committee. The report looks at the Clean Water Rule and addresses four major topics: the Environmental Protection Agencies’ application of economic theory, especially the concept of federalism in environmental regulation; the quality and impact of the agencies’ assumptions in their benefit-cost analyses about likely state reactions to narrowing the Clean Water Act's jurisdiction (i.e., the “federalism scenarios”); the methods used to estimate the forgone benefits from reducing CWA jurisdiction; and the avoided cost estimates in the economic analyses.
