(a) For a proposed floodplain or wetland action for which an EIS is required, DOE shall use applicable NEPA procedures to provide the opportunity for early public review of the proposed action. A notice of intent to prepare the EIS may be used to satisfy the requirement for DOE to publish a notice of proposed floodplain or wetland action.

(b) For a proposed floodplain or wetland action for which no EIS is required, DOE shall take appropriate steps to send a notice of proposed floodplain or wetland action to appropriate government agencies (e.g., FEMA regional offices, host and affected States, and tribal and local governments) and to persons or groups known to be interested in or potentially affected by the proposed floodplain or wetland action. DOE also shall distribute the notice in the area where the proposed action is to be located (e.g., by publication in local newspapers, through public service announcements, by posting on- and off-site). In addition, for a proposed floodplain or wetland action that may result in effects of national concern to the floodplain or wetland or both, DOE shall publish the notice in the Federal Register.
