The NPDES permits program is authorized by CWA section 402. The initial permits issued in the 1970s and early 1980s focused on POTWs and industrial wastewater—typically “process” wastewater and cooling water where applicable, and in some cases, industrial stormwater. The 1987 WQA expanded the program to cover stormwater discharges explicitly, both from municipal separate storm sewer systems (MS4) and industrial sources. The MS4 NPDES permits require regulated municipalities to use Best Management Practices to reduce pollutants to the “Maximum Extent Practicable.”

Protecting Storm Drains and Inlets From Sediment and Pollutants

The trouble with stormwater runoff is that it travels along the ground surface and over pavement, picking up sediment and other contaminants as it goes. A well-designed surface water runoff collection and drainage system will funnel runoff from relatively large areas into individual collection points such as inlets and drains
