JUDGMENT

This petition for review was considered on the record from the Federal Energy Regulatory Commission, was briefed and argued by counsel. It is

ORDERED AND ADJUDGED that the petition for review be denied. The bulk of petitioners’ arguments either directly or indirectly assail the basic concept of the Commission’s longstanding policy of allowing discounts based on differences in demand, which we have found to be within the Commission’s authority under the Nat*118ural Gas Act. Associated Gas Distributors v. FERC, 824 F.2d 981, 1011-12 (D.C.Cir. 1987). With respect to the policy stated in Natural Gas Pipeline Co., 69 FERC ¶ 61,029, 61,116-17, 1994 WL 550607 (1994), regarding the application of discounts to base rates and surcharges, which the Commission evidently assumed would be applicable in principle to the surcharges at issue here, see Northern Natural Gas Co. 99 FERC ¶ 61,051, 61,228, 2002 WL 552276 (2002), petitioners have given no adequate basis for us to conclude that the reasons offered by the Commission for its non-application at this stage, see id. at 61,223-26, are arbitrary and capricious or not in accordance with law.

Pursuant to D.C. Circuit Rule 36, this disposition will not be published. The Clerk is directed to withhold issuance of the mandate herein until seven days after resolution of any timely petition for rehearing or rehearing en banc. See Fed. R.App.P. 41(b); D.C.Cir. Rule 41.
