Concurrent with its review of a proposed action to determine appropriate NEPA or CERCLA process requirements, DOE shall determine the applicability of the floodplain management and wetland protection requirements of this part.

DOE shall determine whether a proposed action would be located within a base or critical action floodplain consistent with the most authoritative information available relative to site conditions from the following sources, as appropriate:

Flood Insurance Rate Maps or Flood Hazard Boundary Maps prepared by FEMA;

Information from a land-administering agency (e.g., Bureau of Land Management) or from other government agencies with floodplain-determination expertise (e.g., U.S. Army Corps of Engineers, Natural Resources Conservation Service);

Information contained in safety basis documents as defined at 10 CFR part 830; and

DOE environmental documents, e.g., NEPA and CERCLA documents.

DOE shall determine whether a proposed action would be located within a wetland consistent with the most authoritative information available relative to site conditions from the following sources, as appropriate:

U.S. Army Corps of Engineers “Wetlands Delineation Manual,” Wetlands Research Program Technical Report Y-87-1, January 1987, or successor document;

U.S. Fish and Wildlife Service National Wetlands Inventory or other government-sponsored wetland or land-use inventories;

U.S. Department of Agriculture Natural Resources Conservation Service Local Identification Maps;

U.S. Geological Survey Topographic Maps; and

DOE environmental documents, e.g., NEPA and CERCLA documents.

Pursuant to § 1022.5 of this part and paragraphs (b) and (c) of this section, DOE shall prepare:

A floodplain assessment for any proposed floodplain action in the base floodplain or for any proposed floodplain action that is a critical action located in the critical action floodplain; or

A wetland assessment for any proposed wetland action.
