摘要

Stormwater issues have long lacked the attentiongiven to other environmental issues consideredto be more “pressing.” One need look no furtherthan the history of the Clean Water Act, amendedby Congress in 1972 to prohibit the discharge of pollutantsto waters of the United States frompoint sources, unless authorized by aNational Pollutant Discharge EliminationSystem (NPDES) permit. That initialfocus was on reducing pollutants frompoint sources—most obviously “sewageplants”; it’s easy to point a finger to aneffluent flowmeter and record the datanecessary to determine the poundsper day of nitrogen discharged to theLong Island Sound, for example. Butas NPDES permits were implemented,it became evident that other, nonpointsources of water pollution stillcontributed to water quality impairment.Stormwater, enter stage right: Finally,in 1987, Municipal Separate StormSewer System (MS4) programs wereintroduced and incorporated into theClean Water Act, with the Phase ⅡFinal Rule published in December 1999.
