Williams Natural Gas Company v. Federal Energy Regulatory Commission, Missouri Public Service Commission, Intervenor

Opinion for the Court filed by Circuit Judge TATEL.

TATEL, Circuit Judge:

A gas pipeline petitions for review of a Federal Energy Regulatory Commission order requiring it to refund interest collected from its customers for the period between the Commission’s approval of the tariff and the date the pipeline eventually billed its customers. Finding that the Commission reasonably concluded that the pipeline’s tariff did not authorize interest collection in cases of delayed billing and that the pipeline lacked adequate justification for delaying billing, we deny the petition for review.
