The Division of Conservation Planning and Policy is responsible for technical assistance, coordination and review of NEPA documents on activities that may effect refuge lands or resources.
That coordination includes:
Internal compliance with NEPA related to refuge proposals and environmental documents;
Refuge involvement with NEPA in the coordination and review of the environmental documents of other federal agencies or public entities proposing to use refuge lands or resources.
The Department of Interior has promulgated regulations on NEPA (pdf) . Our Draft Fish and Wildlife Service Manual on NEPA and our NEPA Reference Handbook contain Fish and Wildlife Service and Department of the Interior NEPA guidance and procedures.
