The State of Tennessee’s Stormwater Management:
Challenges, Opportunities, and Tools

Dr. Daniel Yoder
University of Tennessee
Department of Biosystems Engineering & Soil Science
Knoxville, Tennessee


As the focus of national enforcement of the Clean Water Act shifts from point source to nonpoint source pollution, pressure is mounting to properly manage stormwater runoff and its associated contaminants. During site development, the focus is on erosion and sediment control, but during post-development, the emphasis is on minimizing total impact through maintaining a more “natural” site hydrology. In conjunction with requirements to remove first-flush contaminants normally associated with urban runoff, this is the focus of the Tennessee Permanent Stormwater Permit granted to Tennessee by EPA several years ago, and which is undergoing implementation over the next year. We will first examine the overall conceptual approach to stormwater management and how that differs from the normal hydrologic control we have been doing for a long time to minimize flooding. We will then look at the specifics of the TN Permit and implications for development, followed by a description of the tools being delivered to assist in determining whether proposed designs meet the Permit requirements. Finally, we will discuss the opportunities that this might open up for geologists and other conservationists to participate in the planning and permitting process.


Dr. Daniel Yoder, PhD, P.E., is Professor in the Biosystems Engineering & Soil Science Department at the University of Tennessee, Knoxville (UT), and is Executive Director for the Stormwater Management, Assistance, and Research (SMART) Center, a joint effort of UT AgResearch, UT Extension, the Tennessee Water Resources Research Center, the Tennessee Department of Environment and Conservation, and a consortium of private firms and government agencies. Daniel’s background is in surface water hydrology and stormwater management, with special interests in erosion and sediment control, tools for estimating the impacts of practices to control erosion and stormwater runoff, and hydrologic monitoring. Teaching responsibilities include courses in these areas, as well as directing the Senior Design sequence. Daniel is a member of AAAS, AGU, ASABE, ASCE, WEF, IECA, and is a Fellow of the SWCS.
