    Before TUTTLE, Chief Judge, and JONES and GEWIN, Circuit Judges.
   JONES, Circuit Judge.

Sun Oil Company made a contract on June 10, 1958, for delivery of natural gas from lands designated and described in the contract to Transwestern Pipeline Company. The contract gave Sun the right, subject to some requirements not material here, to commit the gas from certain other described lands to the sale covered by the contract by the unilateral action of giving notice to Transwestern. The contract was tendered to the Federal Power Commission as a rate schedule. It contained a favored-nation escalation clause and a price-redetermination clause. A certificate of public convenience and necessity was issued by the Commission covering only the gas produced from the lands included in the initial commitment of the contract. On March 3, 1961, the Commission adopted its Order No. 232 which, on March 31, 1961, was amended by Order No. 232-A. The orders added to Section 154.93 of the Commission’s Rules and Regulations a proviso relating to contract provisions for price changes. The substance of the proviso, as it may aifect this case, is to render inoperative and of no effect all types of flexible pricing provisions, with some stated exceptions, contained in contracts subject to the jurisdiction of the Commission which are executed on or after April 3, 1961.

On July 3, 1961, Sun gave Transwest-ern notice, pursuant to the contract terms, that additional acreage and the gas to be produced therefrom were being committed to the contract. On July 12, 1961, Sun applied to the Commission for an amendment to its certificate for temporary authorization to sell the gas produced from the lands added to the contract. On September 21, 1961, the Commission issued its letter order granting to Sun temporary authorization to sell gas from the lands added to the contract by the unilateral notice to Transwestern. The order contained a statement that in the event any document executed on or after April 3, 1961, which therein or by adoption provided for rate changes, except those permitted by Section 154.93 of the Commission’s Regulations, such provision will be inoperative and of no effect at law and any rate change under such provisions will be rejected. Sun made an application for a rehearing requesting the removal of this statement. By a letter order dated November 22, 1961, in which the statement is referred to as a proviso, the Commission dismissed the application. Sun has filed in this Court its petition for review of the Commission’s order of September 21, 1961, in so far as it seeks to make inapplicable, to sales of gas from the added lands, the clauses of the original contract for favored-nation escalation and price rede-termination.

In its petition for review Sun asserts that the Commission, in the adoption of Order No. 232 and Order No. 232-A, exceeded the authority conferred upon it by the Natural Gas Act, that the statement or proviso in the letter order is contrary to and goes beyond the provisions of Order No. 232 and Order No. 232-A, that the Commission’s order deprives Sun of property without due process of law and is arbitrary, capricious and unjustly discriminatory. The Commission has moved to dismiss the petition for review for lack of jurisdiction on the ground that the petitioner is not “aggrieved” within the meaning of Section 19(b) of the Natural Gas Act and that it will not be aggrieved unless it attempts to obtain authorization for a rate increase under the flexible price provisions of the original contract and such increase is rejected by the Commission by reason of the provisions of the amendment to the Regulations.

The letter order which Sun seeks to have reviewed is not of a definitive character dealing with the merits of a proceeding before the Commission. It does not presently affect the rights or duties of Sun. It is merely a step in the administrative process and is interlocutory and not reviewable. Shank, Trustee, v. Federal Power Commission, 5th Cir., 1956, 236 F.2d 830, cert. den. 352 U.S. 970, 77 S.Ct. 361, 1 L.Ed.2d 324; Lee, Trustee, v. Federal Power Commission, 5th Cir., 1956, 236 F.2d 835, cert. den. 352 U.S. 970, 77 S.Ct. 361, 1 L.Ed.2d 323. That the language in the letter order of which Sun complains has no coercive effect is shown by the meaning given to it by theCommission. In the Motion to Dismiss of the Commission, it is said:

“Petitioner’s claim of actual controversy appears to be based on the contention that the language it objects to in the certificate represents a Commission decision that Section 154.93 is applicable to this case. In fact, however, the Commission has made no such decision. The language complained of is ‘boiler-plate’ language which has been regularly used in numerous temporary certificates, not as a decision on the facts but as a means of calling the regulation to the attention of the applicant.
“We are authorized to state that the language used was not intended to broaden, narrow, or apply the regulation, or to determine its applicability or scope, or to constitute a condition of the certificate. It is solely of an informatory nature, as was the abandonment language in the Sunray certificate ([Sunray Mid-Continent Oil Co. v. Federal Power Commission, 10 Cir.], 270 F.2d 404 * * *) which called attention to a provision of the Act. Like that language with respect to Sunray, the language here in issue has no present impact on Sun.”

To the extent the foregoing is a construction of the language of the certificate, we adopt it. To the extent it states principles of law, we agree with it. We would add that neither the adoption of the amendments to the Regulations, their mention in the certificate, nor the Commission’s construction of them is in any sense decisive as to their validity. That issue is not now before us. We shall defer our consideration of it until it is properly presented.

The Commission’s motion is granted and the petition for review is

Dismissed.
