Nonpoint Source Program
The Clean Water Act has guided water quality improvement for over 30 years. Montana was successful in limiting pollution from industrial and municipal discharges through point source permits. Today point source pollution impairs only 10 percent of Montana’s streams and 20 percent of its lakes.
Now the challenge is to protect and restore water quality affected by nonpoint source pollution. These sources include grazing, logging, farming, mining, land development and many other activities. Nonpoint sources reduce pollution through voluntarily action.
The Nonpoint Source Pollution Program is designed to encourage voluntary pollution control activities, provide guidance, and match local funding.
