TEMPORARY EROSION CONTROL SELECTION - TAMUBMP COMPUTER PROGRAM. FINAL REPORT

Achieving the maximum environmental benefits of an entire project's lifetime (planning and design phase, construction and maintenance) has become an important goal for the Texas Department of Transportation (TxDOT). With the implementation of the Environmental Protection Agency's National Pollutant Discharge Elimination System (NPDES) permitting requirements in 1992, an increased awareness and pro-active stormwater management program has been developed in TxDOT. During the past twenty years, there has been a proliferation of erosion and sediment control products and methods developed by the erosion industry. Industry standards have not kept up with the rapid changes; therefore, education, testing, and applications vary across the country. Designers need to have the appropriate guidance to be able to meet the demands placed on them today. The researchers evaluated the difficulties encountered during the design and selection process for developing stormwater pollution prevention plans (SW3P) and provided guidance in the following areas: erosion and sediment control functions, application areas, nomenclature, steps to select measures, erosion principles, and erosion prediction factors. Design aids developed include the following: PC-based computer program for SW3P reporting and selection procedures and a final report that includes a glossary for cross-referencing other publications and updated VM and K reference tables.
