only partial reimbursement for taxes. In another contract (the instant case, for example) a pipeline company may obtain the same initial price but in order to do so may have to agree to full reimbursement for taxes at present rates. It is apparent that the second producer has obtained a better price than the first one, for it has been able to pass along all of its volumetric tax costs as a separate item.
It follows from this, we believe, that comparative tax reimbursement plans as well as comparative base rates ought to be taken into consideration in determining whether a proposed initial price is out of line. Except where the difference in tax reimbursement features is relatively insubstantial, it is our opinion that failure to take account of such a difference would be an abuse of discretion.
Summarizing on this branch of the case, we are of the view that with respect to the use for comparative purposes of prices presently under review and the failure to consider tax reimbursement features in making such comparisons, the criteria employed by the Commission in fixing a line by which to test the proposed initial rates of Superior and California fall short of what is required under Cateo and the Act. Since it was apparently upon the basis of a line so determined that the Commission ordered issuance of a permanent and unconditional (as to prices) certificate, we hold that the Commission abused its discretion in so doing and that the order must be set aside.
In view of the conclusion just stated it is not necessary to deal at length with the other arguments which have been advanced by UGI and New York. Since, however, further proceedings before the Commission will now be required, we briefly state our views on other questions which the Commission must again face.
Concerning the adequacy of the evidence to support the Commission findings, it is to be remembered that this is not a rate proceeding. Hence a comprehensive showing such as would therein be required is not necessary. Nevertheless, where the Commission relies upon existing certificated rates in establishing a line, evidence ought to be submitted concerning those rates. The contracts ought to be identified, and each should be subject to test as to arms-length bargaining, identity or similarity of gas production area, nature of gas reserves, quality of gas, facilities to be provided and services, to be performed.
With regard to the factor of triggering of price increases, we find nothing wrong with the Commission finding that United’s other contracts will not be substantially affected. They contain no “favored nation” clauses. The testimony as to a noncontractual “favored nation” policy concerning one customer does not seem to us of sufficient importance to undermine the Commission’s finding. In any event the petitions for rehearing did not raise this question. Hence, in view of section 19(b) of the Act the point may not be raised here. Panhandle Eastern Pipe Line Co. v. Federal Power Commission, 324 U.S. 635, 649, 651, 65 S.Ct. 821, 89 L.Ed. 1241.
The Cateo decision in discussing “triggering” refers not alone to possible increases in the applicant’s rates, but to possible “general price rises.” The Commission order appears to contain no finding as to whether the proposed initial-prices might result in a triggering of general price rises.
The Commission order is vacated and the matter is remanded to the Commission for further proceedings consistent with this opinion.
