Environmental Quality Division

Investigations and Prevention Branch

The Investigations and Prevention (I&P) Branch works with others to conduct field studies to determine sources of pollution and to investigate pollution effects on fish and wildlife and their habitat. We also work with federal and state agencies to assure water quality regulations are protective of threatened and endangered species and other fish and wildlife resources.

Natural Resources Damage Assessment and Restoration (NRDAR) Branch

When oil or hazardous substances enter the environment, fish, wildlife and other natural resources can be injured. Our NRDAR Branch identifies the natural resources injured, determines the extent of the injuries, recovers damages from those responsible, and plans and carries out natural resource restoration activities.
