On December 9, 1999 the US EPA published Phase II of the Clean Water Act. Under Phase II all existing municipal separate storm sewer systems (MS4s) located in “urbanized areas” (as defined by the Bureau of the Census) and construction activities that disturb more than or equal to one acre but less than five acres are required to attain a NPDES permit. The MS4 entities are obligated by Phase II to develop, institute and enforce stormwater management programs. These programs must include the selection and implementation of stormwater best management practices (BMPs) to reduce the pollutant load to receiving waters. The objective of this research was to develop a technically based DSS, which can assist in this compliance of the new NPDES Phase II stormwater regulations.
