(d) Where an environmental impact statement (EIS) has been prepared, consider the specific alternatives analyzed in the EIS when evaluating the proposal which is the subject of the EIS. All Commission officials directly involved in developing, evaluating, and/or reaching decisions on proposed actions shall consider relevant environmental documents and comply with the applicable provisions of the NEPA process.
