Region 9 NPDES Outfalls 2012- Waste Water Treatment Plants

Point geospatial dataset representing locations of NPDES outfalls/dischargers for waste water treatment plants which generally represent the site of the discharge. NPDES (National Pollution Discharge Elimination System) is an EPA permit program that regulates direct discharges from treated waste water that is discharged into waters of the US. Facilities are issued NPDES permits regulating their discharge as required by the Clean Water Act. A facility may have one or more dischargers. The location represents the discharge point of a discrete conveyance such as a pipe or man made ditch. SIC code 4952 was used to extract waste water treatment plants from the database.
