47 CFR § 1.1319 - Consideration of the environmental impact statements.
(a) If the action is designated for hearing:
(1) In rendering an initial decision, the presiding officer (other than the Commission) shall use the FEIS in considering the environmental issues, together with all other non-environmental issues.
(2) When the Commission serves as the presiding officer or upon its review of an initial decision, the Commission will consider and assess all aspects of the FEIS and will render its decision, giving due consideration to the environmental and nonenvironmental issues.
(b) In all non-hearing matters, the Commission, as part of its decision-making process, will review the FEIS, along with other relevant issues, to ensure that the environmental effects are specifically assessed and given comprehensive consideration.
