A number of NPDES permit program areas affect how a municipality handles its sanitary wastewater and stormwater runoff. Properly managed municipal facilities, such as publicly owned treatment works (POTWs), and wastewater systems, such as separate and combined storm sewer systems, play an important role in protecting community health and local water quality.

The NPDES Permitting program offers training courses, workshops, and webcasts to explain the regulatory framework and technical considerations of the NPDES Permit program. These courses are designed for permit writers, dischargers, EPA officials, and other interested parties. 

Other important environmental management and compliance information can be found at the Local Government Environmental Assistance Network (LGEAN).
