(a) An EA prepared for a proposal before the Commission by another agency, entity or person, including an applicant, may be adopted if, upon independent evaluation by the responsible Commission official, it is found to comply with this part and relevant provisions of the CEQ regulations.

(b) When appropriate and efficient, a responsible Commission official may augment such an EA when it is essentially, but not entirely, in compliance in order to make it so.

(c) If an EA or augmented EA is adopted, the responsible Commission official must prepare his/her own NOI or FONSI which also acknowledges the origin of the EA and takes full responsibility for its scope and content.
