Union Electric Co. v. Environmental Protection Agency

No. 74-1542

Argued January 21, 1976

Decided June 25, 1976

427 U.S. 246


Section 110(a)(1) of the Clean Air Act, as added by the 1970 Amendments to the Act, requires that each State formulate, subject to approval by the Administrator of the Environmental Protection Agency (EPA), an implementation plan providing for attainment of national ambient air quality standards, both primary standards (those necessary to protect the public health) and secondary standards (those necessary to protect the public welfare). Section 110(a)(2) provides that the Administrator "shall approve" the proposed plan if it has been adopted after public notice and hearing and meets eight specified criteria, including provisions for attaining the primary standards "as expeditiously as practicable but . . . in no case later than three years from the date of approval of such plan," and of the secondary standards within a "reasonable time," and provisions for such control measures "as may be necessary" to attain both the primary and secondary standards. Section 307(b)(1) of the Act provides that a petition for review of the Administrator's "action in approving. . . [the] implementation plan" may be filed in the appropriate United States court of appeals, and must be filed within 30 days from the date of such approval, or after such date if the petition is based on grounds arising after the 30th day. Petitioner electric utility company, whose coal-fired generating plants are subject to the sulfur dioxide restrictions in the Missouri implementation plan, did not seek review of the Administrator's approval of that plan within the required 30 days, but, rather, applied to the state and county agencies for, and received, one-year variances. At a time when petitioner was seeking extension of these variances, the Administrator notified it that sulfur dioxide emissions from its plants were violating the Missouri plan. Thereupon petitioner filed a petition for review of the Administrator's approval of the plan, claiming that various economic and technological difficulties had arisen more than 30 days after the approval, making compliance with the emission limitations impossible. The Court of Appeals dismissed the petition for lack of jurisdiction, holding that only chanrobles.com-red

matters which, if known to the Administrator at the time he approved the state plan, would justify setting aside the approval are properly reviewable after the 30-day period, and that, since claims of economic and technological infeasibility, such as petitioner was asserting here, could not properly justify the Administrator's rejection of a plan, such claims could not serve at any time as the basis for a court's overturning a plan.


1. Since, regardless of when a petition for review is filed under § 307(b)(1), the court is limited to reviewing "the Administrator's action in approving . . . [the] implementation plan," if new "grounds" are alleged, they must be such that, had they been known at the time the plan was presented to the Administrator for approval, it would have been an abuse of discretion for him to approve the plan. A contrary holding would shift a substantial responsibility in administering the Act from the Administrator and the state agencies to the federal courts. Pp. 427 U. S. 255-256.

2. Since both the language of the relevant provisions of the Clean Air Amendments of 1970, especially § 110(a)(2), and their legislative history make it clear that Congress intended that grounds of economic and technological infeasibility be deemed wholly foreign to the Administrator's consideration of a state implementation plan, a court of appeals reviewing an approved plan under § 307(b)(1) cannot set it aside on such grounds, no matter when they are raised. Pp. 427 U. S. 256-269.

(a) The mandatory "shall" in the provision of § 110(a)(2) that the Administrator "shall approve" an implementation plan if it satisfies the eight specified criteria, clearly indicates that the Administrator is not to be concerned with factors other than those specified, none of which appears to permit consideration of economic or technological infeasibility. P. 427 U. S. 257.

(b) The criterion of § 110(a)(2) that the primary air quality standards be met "as expeditiously as practicable but . . . in no case later than three years," does not require consideration of claims of economic and technological infeasibility, but, as both the language and legislative history of that criterion make clear, it was intended that the Administrator must approve a plan that provides for attainment of the primary standards in three years even if attainment does not appear possible, the three-year deadline being central to the regulatory scheme of technology forcing. Pp. 427 U. S. 257-260.

(c) The criterion of § 110(a)(2) that the state implementation plan contain such control measures "as may be necessary" to achieve the primary and secondary standards does not preclude chanrobles.com-red

a State from submitting a plan more stringent than federal law demands, but such requirement demands only that the proposed plan meet the minimum requirements of § 110(a)(2), and provides no basis for the Administrator ever to reject a sate implementation plan on the ground that it is economically or technologically infeasible. Pp. 427 U. S. 260-265.

(d) Since the 1970 Amendments to the Act afford ample opportunity for considering claims of economic and technological infeasibility as long as there will not be substantial interference with the primary goal of promptly attaining the national standards, to allow such claims to be raised by appealing the Administrator's approval of an implementation plan would frustrate congressional intent; would permit a proposed plan to be struck down as infeasible before it is given a chance to work, even though Congress clearly contemplated that some plans would be infeasible when proposed; and would also permit the Administrator or a federal court to reject a State's legislative choices in regulating air pollution, even though Congress plainly left with the States, so long as national standards were met, the power to determine which sources would be burdened by regulation and to what extent. Pp. 427 U. S. 266-269.

515 F.2d 206, affirmed.

MARSHALL, J., delivered the opinion for a unanimous Court. POWELL, J., filed a concurring opinion, in which BURGER, C.J.,joined, post, p. 427 U. S. 269. chanrobles.com-red
