The Stormwater Blogs

Gordon England, P.E., D.WRE, president of Stormwater Solutions, Inc. and Stuart Stein, P.E., D.WRE, president of GKY and Associates will be conducting the one day pre-conference course entitled Practical Stormwater Treatment From A-Z: A Special Training Opportunity for Stormwater Managers and Consultants. This course offering will be held Monday August 17, 2009 from 8:30 to 4:30.

Course Description:

Selecting the right Best Management Practices (BMPs) is crucial for achieving water-quality goals. Understanding the array of choices and the conditions in which different BMPs are most effective is equally critical. This comprehensive workshop guides program managers and engineers through the criteria necessary to make appropriate selections. It begins with a discussion on types of pollutants and their sources and moves into an overview of pollutant removal unit processes. Discussion follows addressing impaired waters and TMDLs, and the difference between new development BMP design and retrofitting existing development for TMDL compliance. A detailed description of 33 BMPs is given - from ponds, alum injection systems, and constructed wetlands, to various types of media filters, inlet devices, sand filters, hydrodynamic devices, and more. A section on selection criteria gives participants a list of factors for making the best choices, including not only pollutant removal effectiveness, but also types of pollutants, available space, groundwater level, soil type, and maintenance costs. The workshop also includes discussions of first flush, monitoring of BMPs, BMP databases, and the role of low-impact development practices and stormwater reuse. Various models of pollutant loading calculations for TMDL compliance and pollutant removal calculations for BMPs and treatment trains are demonstrated, along with a method for designing pre vs. post pollutant loadings. An in depth look at BMP inspections and maintenance will also be given along with a method to track sediment removals from street sweeping and maintenance activities to achieve reductions in TMDL allocations.

Instructors:
Gordon England, P.E., D.WRE, president of Stormwater Solutions, Inc. Gordon England has over 30 years of experience in stormwater management, in both the public and private sectors. His experience includes stormwater master plans, modeling, stormwater utility creation and management, and grant acquisition. His 10 years as lead engineer with the Brevard County (FL) Stormwater Utility and tenure as senior engineer for the Bahamian Ministry of Works gives him a thorough understanding of municipal operations and perspectives. He is a recognized leader in the selection and design of innovative stormwater BMPs and serves as an editorial advisor to Stormwater magazineand on several task committees for the Environmental Water Resources Institute.

Stuart Stein, P.E., D.WRE, president of GKY and Associates
Stuart Stein has 22 years of experience in stormwater management and water resources engineering, including watershed management plans, stormwater and drainage studies, BMP design and analysis, TMDLs, and flood studies. He has coauthored several publications, including the Federal Highway Administration’s popular Evaluation and Management of Highway Runoff Water Quality, and its Urban Drainage Design Manual, Hydraulic Engineering Circular No. 22. He assisted the EPA’s Office of Policy in evaluating the impacts of land development alternatives (e.g., traditional sprawl, smart growth) on water quality. Stein serves on the faculty of the Catholic University of America’s civil engineering department, where he teaches environmental systems design, water-supply engineering, and wastewater engineering. He was chair of the ASCE's National Urban Water Infrastructure Management Committee and chair of the ASCE TMDL Evaluation Task Committee.
