NPDES - National Pollutant Discharge Elimination System
The Clean Water Act established the National Pollutant Discharge Elimination
System (NPDES) program to control the discharge of pollutants through implementation
of water quality standards and Federal technology-based standards and requirements
in a permitting system. These NPDES permits protect receiving waters from the
discharge of toxic material in toxic amounts. For Publicly-Owned Treatment Works,
or POTWs, these NPDES permits may establish pretreatment program requirements
to protect the POTW and may also specify acceptable practices for the disposal
of municipal sewage sludge, or biosolids. The Stormwater Program ensures that
precipitation runoff from designate facilities does not cause adverse impacts.

The EPA NPDES Permitting Program directly issues permits for Federal
Facilities in Colorado, Indian Country permits, and provides permit
oversight activities for the Region 8 states.
Coal Bed Methane (CBM) is fast becoming
an important issue in western states. EPA Region 8 is working
with the states to effectively deal with these sources.

The Industrial Pretreatment Program
ensures that discharges to the sanitary sewer system from industrial
and commercial dischargers do not cause Pass Though of toxic pollutants
or Interference with sewer system or treatment works and improve
the opportunity for the benefical reuse of biosolids.
|
|
The Biosolids Program ensures
that sewage sludge is of suffucient quality to protect public
health and the environment. The program also promotes the
beneficial reuse of biosolids.
|
|
The Stormwater
Program requires management practices to ensure that pollutants
are not transported in runoff from industrial facilities and urban
storm water collection systems.

Concentrated Animal Feeding Operations (CAFOs) have become a
significant environmental concern. EPA is focusing resources
on these operations.
