Background
Storm water discharges are generated by runoff
from land and impervious areas such as paved streets, parking lots, and
building rooftops during rainfall and snow events that often contain
pollutants in quantities that could adversely affect water quality. Most storm
water discharges are considered point sources and require coverage by an NPDES
permit. The primary method to control storm water discharges is through the
use of best management practices (BMPs).
