Discharging HSTS

What is an NPDES System?

Since its introduction in 1972, the NPDES permit program is responsible for significant improvements to our nation's water quality.  NPDES, or National Pollutant Discharge Elimination System, controls water pollution by regulating point sources that discharge pollutants into waters of the United States. Water pollution degrades surface waters making them unsafe for drinking, fishing, swimming, and other activities. Individual homes, industrial, municipal, and other facilities must obtain permits if their discharges go directly to surface waters. (Reference: http://water.epa.gov/polwaste/npdes/)
