Présentation
The U.S. Environmental Protection Agency’s (EPA’s) Office of Research and Development and U.S. EPA Region 6 conducted a study that evaluated the use of best management practices (BMPs) for stormwater management in an arid climate. The System for Urban Stormwater Treatment and Analysis INtegration (SUSTAIN) was the platform used for this study. The focus area is in the Albuquerque metropolitan area in north-central New Mexico and lies along an urban portion of the Middle Rio Grande watershed that was listed for Escherichia coli (E. Coli) impairment as part of a recent total maximum daily load (TMDL). The study investigates both site- and regional-scale stormwater management questions ahead of a pending municipal separate storm sewer system (MS4) watershed-based permit (WBP). With the large degree of variability in physical, hydrological, and chemical characteristic in a watershed, watershed-scale management for the nonpoint source component of MS4 permits quickly grows in complexity. Given the heterogeneity of contributing pollutant sources, managing the watershed in one way versus another might result in significant cost differences between strategies that yield comparable water quality outcomes.
