The Environmental Protection Agency ("EPA") concluded that the Tennessee Valley Authority ("TVA") violated the Clean Air Act ("CAA")1 when it undertook fourteen rehabilitation projects at nine coal-fired electric power plants without permits. The EPA then issued an administrative compliance order ("ACO"), which required that TVA undertake several costly and burdensome compliance initiatives. TVA contended that the EPA had an incorrect understanding of the law and facts, and it therefore refused to comply with the terms of the ACO. Believing that TVA could not be sued in federal court,2 the EPA created a scheme in which the Environmental Appeals Board ("EAB") was delegated the task of "reconsidering" the ACO by informally adjudicating the issue of liability. After the EAB decided that TVA did, in fact, violate the CAA when it undertook the rehabilitation projects without permits, TVA filed a petition for review in this court, asking us to set aside the EAB Order as unlawful and the product of "arbitrary and capricious" decision-making pursuant to the Administrative Procedure Act's ("APA") judicial review provision, 5 U.S.C. § 706(2)(A).

We hold that we lack jurisdiction to review the ACO because it does not constitute "final" agency action. Although the CAA empowers the EPA Administrator to issue ACOs that have the status of law,3 we believe that the statutory scheme is unconstitutional to the extent that severe civil and criminal penalties can be imposed for noncompliance with the terms of an ACO. Accordingly, ACOs are legally inconsequential and do not constitute final agency action. We therefore decline to assert jurisdiction over TVA's petition for review pursuant to 42 U.S.C. § 7607(b)(1).4 The EPA must prove the existence of a CAA violation in district court; until then, TVA is free to ignore the ACO without risking the imposition of penalties for noncompliance with its terms.

This opinion consists of six parts. In part I, we describe the CAA's enforcement scheme. An important component of this discussion is the following observation: Congress clearly intended that ACOs be issued without any sort of adjudication, and the EPA has always (until now) abided by this obvious interpretation. This part also describes the course of this litigation, detailing the EPA's decision to conduct an adjudication prior to the issuance of the ACO — an adjudication that employed procedural rules that were invented by the EAB and administrative law judge ("ALJ") and applied on an ad hoc basis. Part II provides an overview of the Supreme Court's finality doctrine. This part concludes by focusing the discussion on one essential finality factor: whether the agency's action fixes a legal right or obligation. Although we ultimately believe that the CAA clothes ACOs with the status of law, part III explains why this conclusion is not axiomatic, notwithstanding the plain language of the statute. Several factors that might inform our interpretation of the CAA — agency practice, legislative history, the canon of statutory construction which requires courts to interpret statutes in a way that renders them constitutional, the problem of judicial review, and statutory structure — all point to the conclusion that Congress did not intend that ACOs have the status of law. Part IV explains how the plain language of the CAA leads to the unavoidable conclusion that Congress did, in fact, authorize the issuance of ACOs with the status of law. In this vein, the tension between parts III and IV reveals that the CAA was poorly drafted. Part V explains why the CAA is unconstitutional to the extent that monetary penalties and imprisonment can be imposed merely for noncompliance with an ACO. This part also explains why the statute cannot be saved by a voluntary pre-ACO adjudication. Part VI, the conclusion, makes the following point: since a deprivation of liberty or property cannot stem from mere noncompliance with an ACO, ACOs have no legal consequence and therefore do not constitute final agency action. Not only is this result constitutionally compelled, it also enables future courts to sidestep the thorny problems presented by part III, such as the fact that ACOs are typically issued without a record and the fact that an EPA adjudication of liability conflicts with other provisions of the statutory scheme.

When the EPA finds that a regulated party is engaging in some sort of unlawful activity — such as emitting pollutants in excess of that allowed by EPA regulations or constructing a pollution source without a permit required by a state implementation plan ("SIP")—the EPA has four enforcement options. First, the EPA can request that the Attorney General commence a criminal prosecution. See 42 U.S.C. § 7413(a)(3)(D), (c).5 Second, the EPA can file suit in district court and seek injunctive relief and the imposition of civil fines.6 See 42 U.S.C. § 7413(a)(1)(C), (a)(2)(C), (a)(3)(C), (b). Third, the EPA can, after a formal adjudication of liability consistent with the APA7 and 40 C.F.R. § 22,8 assess civil penalties against the violator. See 42 U.S.C. § 7413(d). Whenever any of these three enforcement methods is used, the following fact remains true: if the defendant believes that the EPA has based its conclusions upon erroneous facts or an incorrect understanding of the law, the defendant may make legal and factual arguments in an independent forum — one that enables the defendant to utilize a panoply of pre-established procedural rights.

The EPA also has a fourth option: it can issue an ACO directing the regulated party to comply with various requirements. See 42 U.S.C. § 7413(a)(1)(A), (a)(2)(A), (a)(3)(B), (a)(4). ACOs can be issued so long as the following requirements are met: (a) they must be based upon "any information available to the Administrator"; (b) they must be issued thirty days after the issuance of a Notice of Violation; and (c) the regulated party must be given an "opportunity to confer" with the Administrator. See 42 U.S.C. § 7413(a)(1), (4).

The problem with ACOs stems from their injunction-like legal status coupled with the fact that they are issued without an adjudication or meaningful judicial review. First, ACOs are issued without any sort of adjudication that a party has violated the CAA. Like the decision to pursue a civil enforcement action in district court and the decision to refer a potential criminal violation to the Attorney General, the decision to issue an ACO is made "on the basis of any information available to the Administrator." 42 U.S.C. § 7413(a)(1). That is, the Administrator need only have a staff report, newspaper clipping, anonymous phone tip, or anything else that would constitute "any information." The standard is less rigorous than the probable cause standard required for the issuance of search warrants; certainly no pre-ACO adjudication that a party has violated the CAA (such as by modifying a pollution source in violation of an SIP) is contemplated. This observation is confirmed not only by the language of the statute, but also by agency practice. ACOs are rarely, if ever, issued after an agency adjudication.9 Finally, section 7413(d) explicitly requires an adjudication before the EPA can assess civil penalties, underscoring the fact that when Congress wants the EPA to conduct an adjudication, it knows how to effectuate that result. In sum, the statute's language and structure, in addition to agency practice, make clear that ACOs are issued without any adjudication.

A second aspect of ACOs is that they have the status of law. The other three enforcement options dovetail with the ACO provisions, making a violation of an ACO a freestanding violation. That is, a violation of an ACO can itself serve as the basis for the imposition of extensive civil fines or imprisonment. Section 7413(b), for example, provides that a civil action can be commenced not only when a person has violated an SIP or EPA regulation, but also after a party fails to comply with an "order." Similarly, section 7413(c)(1) provides that "[a]ny person who knowingly violates ... any order under subsection (a) of [42 U.S.C. § 7413] ... shall, upon conviction, be punished by a fine pursuant to Title 18, or by imprisonment for not to exceed 5 years, or both." Criminal liability can also be predicated upon a violation of an ACO issued pursuant to 42 U.S.C. § 7477. Finally, the EPA can administratively assess civil penalties based upon the violation of any "order" issued by the EPA. See 42 U.S.C. § 7413(d). Apparently dissatisfied with the dispensation of justice by the federal courts, Congress empowered the EPA to decide the central question of whether a regulated party has complied with an SIP or EPA regulation. Once the EPA has decided the underlying issue of liability, it can issue an injunction-like order which, upon noncompliance, leads to a host of severe penalties. The following scenarios illustrate the scheme:

Scenario One: The EPA Administrator reads a newspaper report stating that Energy Co. has modified a power plant without a permit. The EPA also receives an anonymous phone tip "confirming" the report. Based upon the newspaper's discussion of the precise nature of the modifications, the Administrator believes that the modifications are so extensive that Energy Co. is in violation an SIP. That is, the Administrator finds that there has been a violation of an applicable implementation plan based upon "any information available to the Administrator." 42 U.S.C. § 7413(a). The Administrator gives the requisite "Notice of Violation" to Energy Co., and Energy Co. vehemently disagrees with the EPA. It believes that the EPA has based its finding upon an erroneous view of the law and facts, and so it does nothing in response to the Notice of Violation. After 30 days, the Administrator issues a highly detailed administrative compliance order pursuant to 42 U.S.C. § 7413(a)(1). The Administrator provides Energy Co. with an "opportunity to confer," see § 7413(a)(4), hoping that she can settle the matter with Energy Co. and thereby avoid the difficult and costly task of proving a violation in court. The Administrator revises the ACO several times, but to no avail; Energy Co. continues to believe that the Administrator's view of the law and facts is wrong. After conducting an investigation so that it can make out a complaint against Energy Co., the EPA takes the following course of action: first, the EPA seeks to administratively assess civil penalties against Energy Co. pursuant to section 7413(c); second, the agency seeks an injunction in district court pursuant to section 7413(b); third, because the EPA believes that Energy Co. is a "knowing violator" of the SIP under section 7413(d), it asks the Attorney General to bring a criminal action against Energy Co. In all three forums — the civil suit seeking an injunction, the intra-agency proceeding seeking civil penalties, and the criminal prosecution seeking imprisonment — Energy Co. is allowed to contest EPA's view of the facts and law. In each case, the original tribunal or a reviewing court might decide that the EPA has failed to prove that Energy Co. has violated an SIP or EPA regulation.

Scenario Two: Just like Scenario One, the EPA Administrator reads a newspaper report stating that Energy Co. has been undertaking various modifications to a power plant without a permit. She also receives an anonymous phone tip "confirming" the report. Based on the newspaper's discussion of the precise nature of the modifications, the Administrator believes that the modifications are so extensive that Energy Co. is in violation of an SIP. That is, the Administrator finds that there has been a violation of an applicable implementation plan based upon "any information available to the Administrator." 42 U.S.C. § 7413(a). The Administrator then gives a "Notice of Violation" to Energy Co. Energy Co., believing that the EPA has based its finding upon an erroneous view of the law and facts, does nothing in response to the Notice of Violation. The Administrator responds by issuing a highly detailed administrative compliance order pursuant to 42 U.S.C. § 7413(a)(1).

At this point, the story begins to change dramatically from Scenario One. The Administrator provides Energy Co. with an "opportunity to confer," see 42 § 7413(a)(4), although the "opportunity" is really no opportunity at all because the Administrator has no intention of changing the ACO. After a few weeks, Energy Co. still has not complied with the terms of the ACO, because Energy Co. continues to believe that the Administrator has an incorrect understanding of the law and facts. The EPA responds by filing an action for the assessment of civil fines pursuant to section 7413(d), in addition to referring the matter to the Attorney General for prosecution. The only issue in each proceeding is whether Energy Co. did, in fact, violate the terms of the ACO. Energy Co. does not have a chance to contend that the EPA has an incorrect view of the facts and law; these issues are irrelevant. Each proceeding involves a brief hearing, with the EPA proffering irrefutable evidence that (a) an ACO was properly issued by the Administrator based upon "any information" available to her (i.e., the newspaper article and anonymous phone tip) and (b) Energy Co. refused to comply with the ACO. Energy Co. is subsequently fined $25,000 per day, and the CEO of Energy Co. is hauled off to prison for five years.

In short, because an ACO can be issued "on the basis of any information available" to the Administrator, and because noncompliance with an ACO automatically triggers civil and criminal penalties, Energy Co. and its corporate officers never get an opportunity to argue, before a neutral tribunal, that the modifications in question do not violate an SIP. The EPA is the ultimate arbiter of guilt or innocence, and the courts are relegated to a forum that conducts a proceeding, akin to a show-cause hearing, on the issue of whether an EPA order has been flouted. As will be discussed infra, this scheme violates the Due Process Clause and the separation-of-powers principle. Our task for the moment is merely to describe how the scheme works.

The Tennessee Valley Authority ("TVA"), an agency of the United States, was established pursuant to the Tennessee Valley Authority Act of 1933, 16 U.S.C. §§ 831-831ee. One of its primary responsibilities is to provide electric power at reasonable rates. 16 U.S.C. § 831n-4(h). To satisfy the statutory directive, TVA owns and operates eleven coal-fired electric power plants,10 most of which were built between the 1950s and the 1970s.

Beginning in the late 1970s, TVA began to plan a series of projects involving the replacement of various boiler components11 at its coal-fired plants, which were carried out between 1982 and 1996. In 1999, the EPA arrived at the conclusion that these projects did not constitute "routine maintenance" as provided for in the exception to the "physical change" component of the "modification" definition set forth in the regulations promulgated under the CAA.12 Accordingly, the EPA believed that the projects triggered New Source Review ("NSR"),13 New Source Performance Standards ("NSPS"),14 and the requirements of various SIPs.

On November 3, 1999, the EPA issued its first ACO,15 requiring TVA to identify any modifications undertaken without permits, apply for the permits, and enter into a compliance agreement with the EPA. Between January and May of 2000, TVA and the EPA held a series of negotiations, leading to six separate amendments to the ACO. After the EPA issued its sixth amended ACO, TVA held firm to its view of the facts and law — namely, that (a) the "modifications" at issue constituted "routine maintenance" and a permit was therefore not required;16 (b) no increase in emissions could be traced to the modifications; and (c) the EPA suddenly changed its definition of "modification" to encompass projects undertaken decades ago, thereby violating the fair notice concepts found in the Constitution's Due Process Clause and administrative common law.17 On May 4, 2000, the EPA informed TVA by letter that it was going to "reconsider" the ACO and directed TVA to comply with the ACO in the meantime. TVA petitioned this court for review of EPA's "notice of reconsideration" on May 12, 2000.

Rather than issuing a seventh amended ACO after staff deliberation, the EPA took a step that it describes as "exceedingly unusual":18 it decided to "reconsider" the ACO by "adjudicating" the issue of whether TVA had violated the CAA when it undertook several plant modifications without a permit.19 The Administrator delegated the task of "reconsidering" the ACO to the EAB, which she was entitled to do by law. See 40 C.F.R. § 1.25(e) (giving the EAB authority to exercise any authority delegated to it, including the authority to "serve as the final decisionmaker, as the Administrator deems appropriate"). Thus, the EAB, enlisted to serve as a proxy for the Administrator, possessed the Administrator's authority to issue the EPA's "reconsidered" ACO.

The EAB crafted a reconsideration procedure which, to say the least, lacked the virtues of most agency adjudications.20 First, the ALJ was instructed by the EAB not to make any findings of facts and conclusions of law. Adjudications typically have statutory protections guaranteeing the ALJ's independence from the heads of the agencies in which they serve. See 5 U.S.C. § 7521. The EAB, by contrast, is a delegatee of the Administrator and is located within the Administrator's Office. See 57 Fed.Reg. 5320, 5320-22 (Mar. 1, 1992). Second, discovery was effectively unavailable: TVA was not entitled to any compulsory process and therefore had to utilize only those documents that the EPA voluntarily divulged; TVA was not allowed to take several depositions; and the EPA made available its hefty privilege log only after the hearing concluded. Third, the testimony that was allowed at the hearing was again "limited" at the behest of the Administrator. Fourth, the proceeding was rushed, giving TVA little time to prepare its defense. TVA was given less than eight weeks of advance notice of the hearing, and the basis of EPA's case was not divulged until three weeks before the hearing. The reasoning behind EPA's finding that TVA's projects caused emissions increases were not divulged at all prior to the hearing. Moreover, TVA was entitled to no more than two weeks to identify witnesses in a regulatory matter spanning over twenty years. TVA was not granted any time extensions to conduct discovery and prepare its case. Fifth, the EAB and ALJ manufactured the procedures they employed on the fly, entirely ignoring the concept of the rule of law. Although the EAB said that the EPA's Consolidated Rules of Practice ("CRP"), 40 C.F.R. § 22, could serve as an adjudicatory model, the rules were only to be used for "guidance." See, e.g., In re Tenn. Valley Auth., CAA Docket No. 00-6, at 20 n. 11 (Sept. 15, 2000) (hereinafter "EAB Order"). The EAB admonished TVA that the proceeding "is not a formal [40 C.F.R. § 22] proceeding, that TVA is not entitled to discovery, and that the schedule in this proceeding has granted TVA significantly greater discovery and hearing rights than required by CAA § 133(a), 42 U.S.C. § 7413(a)."21 EAB Order, at 17. The rules were applied on a purely ad hoc basis. For example, under 40 C.F.R. § 22.27(a), the "Presiding Officer" (e.g., an ALJ) is required to render an "initial decision." The ALJ in this case had no such authority. The ALJ also refused to apply CRP in upholding EPA's objections to TVA's document requests. Sometimes, the ALJ likened the sixth amended ACO to a "complaint" so as to permit the EPA to supplement the record; other times, the ALJ referred to the ACO as a mere "compliance order" and used this categorization to bar TVA's discovery. Describing the procedural framework being employed, the ALJ said: "There's no question about it. This is an invented ... ad hoc procedure.... It's not described in any rule or regulation or statute ... and that's the only way to look at it. There is no precedent." Transcript of June 7, 2000 Pre-Hearing Conference at 74-75, R6-99.

The EAB ultimately "affirmed" most of the sixth amended ACO on September 15, 2000. Both during the EAB proceeding and after it concluded, the EPA operated under the mistaken assumption that an ACO issued after an ad hoc "adjudication" could somehow possess a different legal status than an unadjudicated ACO. The EAB, for example, consistently called the product of the EAB decision a "Final Order" while calling all prior ACOs "compliance orders." The EAB also said that "since the Administrator has directed us to reconsider the Compliance Order, we will characterize the Compliance Order's findings as allegations that must be proven in order to prevail on reconsideration, and the actions required by the Compliance Order as requests for relief." EAB Order, at 5-6. The EAB thus characterized the sixth amended ACO as something akin to a complaint, thereby implying that its final decision, based upon a proceeding that purported to be an agency adjudication, was a different animal. The EPA's brief continues to support the fanciful view that the adjudication conducted by the ALJ and EAB somehow magically transformed the ACO into something else. By way of background (which will be discussed infra), the EPA has consistently contended that pre-enforcement review of ACOs is unavailable because ACOs allegedly trigger no legal consequences upon noncompliance with their terms. But an adjudicated ACO, the EPA argues, is somehow a different creature: "In stark contrast to the ACO, the EAB Final Order constituted a full and complete adjudication by the EAB of the legal and factual issues. Accordingly, the EPA does not contend that ... this is the kind of action as to which Congress intended to bar pre-enforcement review." See Second Brief of Respondents, at 1 n. 4.

On November 13, 2000, TVA petitioned this court for review of the EAB Order pursuant to 42 U.S.C. § 7607(b), which provides for appellate review of any "final agency action of the Administrator." We bifurcated our review of TVA's petitions for review, dealing first with several threshold issues in our opinion of January 8, 2002. See Tenn. Valley Auth. v. EPA, 278 F.3d 1184 (11th Cir.2002). We held that the petitions for review of the pre-adjudication ACOs were moot because the EAB Order rendered the first ACOs "of no force and effect." Id. at 1191. We also held that TVA possessed independent litigating authority; that the dispute presented a justiciable case or controversy; that Executive Orders 12146 and 12088 did not preclude jurisdiction;22 and that various petitioners had standing. Id. at 1191-1209. Finally, we held that the EAB Order was a reviewable final order, id. at 1198-99, asserting in a footnote that "we are not persuaded that a compliance order may not be reviewed prior to an enforcement action." Id. at 1198 n. 21. After further reflection, we no longer believe that the EAB Order constitutes final agency action, and we therefore withdraw the part D of our previous opinion to the extent that it expresses a contrary view.

II. Discussion of Finality, Part One: The Law of Finality and Why it Matters

A. Appellate Review Provision: Why Finality Matters for Jurisdiction

The CAA provides that judicial review of any final EPA action is available "in the United States Court of Appeals for the appropriate circuit." 42 U.S.C. § 7607(b); Harrison v. PPG Indus., Inc., 446 U.S. 578, 100 S. Ct. 1889, 64 L. Ed. 2d 525 (1980).23 Thus, this court has jurisdiction only if the EPA's action constitutes final agency action.

The Supreme Court has established five factors for determining finality: (1) whether the agency action constitutes the agency's definitive position; (2) whether the action has the status of law or affects the legal rights and obligations of the parties; (3) whether the action will have an immediate impact on the daily operations of the regulated party; (4) whether pure questions of law are involved; and (5) whether pre-enforcement review will be efficient. See FTC v. Standard Oil of Calif., 449 U.S. 232, 239-43, 101 S.Ct., 488, 493-95, 66 L. Ed. 2d 416 (1980). The second prong is especially important in this case. In Standard Oil, the Court distinguished the regulations at issue in Abbott Labs. v. Gardner, 387 U.S. 136, 149, 87 S. Ct. 1507, 1516, 18 L. Ed. 2d 681 (1967), on the ground that the regulations had a "direct and immediate ... effect on the day-to-day business" of the complaining parties because they had "`the status of law.'" Standard Oil, 449 U.S. at 239-40, 101 S. Ct. at 493. In this vein, the Court rejected the petitioner's argument that the FTC's actions had legal significance: "Socal does not contend that the issuance of the complaint had any such legal or practical effect, except to impose upon Socal the burden of responding to charges made upon it. Although this burden is certainly substantial, it is different in kind and legal effect from the burdens attending what heretofore has been considered to be final agency action." Id. at 242, 101 S. Ct. at 494. Similarly, in Bennett v. Spear, 520 U.S. 154, 117 S. Ct. 1154, 137 L. Ed. 2d 281 (1997), which was recently affirmed in Whitman v. American Trucking Ass'ns, Inc., 531 U.S. 457, 121 S. Ct. 903, 149 L. Ed. 2d 1 (2001), the Court explained as follows:

As a general matter, two conditions must be satisfied for agency action to be "final": First, the action must mark the "consummation" of the agency's decision making process — it must not be of a merely tentative or interlocutory nature. And second, the action must be one by which "rights or obligations have been determined," or from which "legal consequences will flow."

Bennett, 520 U.S. at 177-78, 117 S. Ct. at 1168 (citation omitted). The second Standard Oil prong, then, is not merely thrown into a totality-of-the-factors balancing test; it is mandatory. The second Bennett factor—whether the agency action is one in which "rights or obligations have been determined" or from which "legal consequences will flow" — is central to our position that ACOs are not final.24

III. Discussion of Finality, Part Two: Why Congress May Not Have Empowered the EPA to Issue ACOs with the Status of Law

It is entirely possible that Congress wanted the EPA to issue inconsequential, complaint-like instruments rather than ACOs with the status of law. That is, one can make a solid argument that Congress never clothed ACOs with the status of law, and that Congress believed that ACOs would not be subject to judicial review.

A. Avoiding an Unconstitutional Interpretation

One reason that a court might interpret the CAA in a way that diminishes the legal significance of ACOs is the fact that the statutory scheme dictated by the plain language of the statute is constitutionally repulsive. As part V.B, infra, explains, the "status of law" interpretation renders the statute unconstitutional, and courts are loath to infer a congressional intention to enact unconstitutional legislation. See Pub. Citizen v. United States Dep't of Justice, 491 U.S. 440, 465-66, 109 S. Ct. 2558, 2572-75, 105 L. Ed. 2d 377 (1989).

B. Statutory Structure and the Problem of Superfluous Provisions

To ascertain the true meaning of a statute, courts are often forced to delve into the structure of a statute and the context in which different provisions are written. See, e.g., United States v. Tinoco, 304 F.3d 1088, 1105 (11th Cir.2002). Using this methodology, it becomes apparent that an interpretation that would give ACOs the status of law renders several statutory provisions useless or absurd.

Perhaps most telling is 42 U.S.C. § 7603, which gives the EPA special "emergency powers." When a pollution source presents an "imminent and substantial endangerment to public health or welfare, or the environment," the EPA may bring suit for appropriate relief. If it is "not practicable to assure prompt protection of public health or welfare" by recourse to a judicial forum, then the EPA may issue an "order" on its own initiative. This order "remains in effect" for, at most, sixty days. To secure a permanent injunction, the EPA must sue in district court. If the order is flouted by the alleged violator, the full panoply of penalties can be imposed, including imprisonment pursuant to 42 U.S.C. § 7413(c)(1).

It is clear from the text of section 7603 that Congress enabled the EPA to issue orders with the status of law, but only in an extremely narrow context. There must be an emergency rising to the point of an "imminent and substantial endangerment." Moreover, the EPA order attains an injunction-like status only for an extremely short time period; any extension must be made by a federal court based upon proof that the defendant has caused extremely harmful pollution. And in the event of an "imminent and substantial endangerment," the EPA does not have unfettered discretion to enter a short-term, injunction-like order. The agency must first resort to a judicial forum; only if that option proves to be impracticable is the EPA justified in issuing such an order. Finally, the EPA is forced to "consult with appropriate State and local authorities and attempt to confirm the accuracy of the information on which the action proposed to be taken is based."

Congress thus authorized the issuance of EPA orders with the status of law, but only in an extremely narrow setting (public emergency), as a last resort (if suing in federal court is impracticable), for a very limited time (sixty days), and after the EPA confirms its information with state and local authorities. Why would Congress cabin EPA orders in this way if the EPA can always issue an identical order (i.e., an ACO) pursuant to 42 U.S.C. § 7413? After all, section 7413 ACOs are of an infinite duration, and they can be issued without going to court — even if recourse to a judicial forum is not "impracticable." Moreover, section 7413 ACOs can be issued "on the basis of any information" that a violation has been committed; there is no need to worry about whether the violation constitutes a rare public emergency, and there is no need to consult sate and local authorities. In sum, section 7603 evidences a congressional intent to permit the EPA to issue orders with the force of law, but only so long as rigorous requirements are met. Section 7413 apparently erases all of those requirements.

Section 7413(c)(1) states that "any person who knowingly violates any ... order under [42 U.S.C. § 7413(a) ] ... shall, upon conviction, be punished by a fine pursuant to Title 18, or by imprisonment for not to exceed 5 years, or both." When read literally, this provision mandates that a knowing violation of the terms of an ACO can lead to imprisonment. The question for the district court is not whether the defendant has, in fact, polluted in violation of an SIP. Rather, the issues before the court are simply (a) whether an ACO has been issued and (b) whether the defendant has complied with its terms.25

This interpretation is, to say the least, bizarre when one reads the rest of the statute. The other criminal provisions require the Government to prove that a defendant has negligently or knowingly released hazardous pollutants. See 42 U.S.C. § 7413(c)(4), (5). Why would Congress bother with requiring the use of the full panoply of procedural rights found in the Federal Rules of Criminal Procedure when the EPA could simply issue an ACO based upon "any information," and, upon noncompliance with the ACO, obtain a conviction? For that matter, the EPA has a strong incentive to avoid proving a violation of an EPA regulation or SIP in any forum — including a civil proceeding in district court or an administrative proceeding before an ALJ. If the EPA issues an ACO, it can always avoid the arduous task of proving the violation in court. The ACO provision appears to be a loophole of the highest order.

Section 7413 also provides that ACOs cannot take effect until the regulated party has had an "opportunity to confer" with the EPA. See 42 U.S.C. § 7413(a)(4). Why did Congress include this language? If ACOs do not have the status of law, then this provision makes sense: ACOs are merely complaint-like devices that are used in an effort to avoid recourse to litigation. They are, in short, the beginning of the bargaining process. See Lloyd A. Fry Roofing Co. v. EPA, 554 F.2d 885, 890-91 (8th Cir.1977); Asbestec Const. Servs., Inc. v. EPA, 849 F.2d 765, 769 (2d Cir.1988). But if noncompliance with an ACO can really trigger civil and criminal penalties, then what incentive does the EPA have to "confer" with the regulated party? If the EPA can issue what is, in effect, an injunction, the EPA would rarely feel compelled to compromise.

An agency's interpretation of its enabling legislation often deserves deference. See Chevron U.S.A., Inc. v. Natural Res. Def. Council, Inc., 467 U.S. 837, 104 S. Ct. 2778, 81 L. Ed. 2d 694 (1984). The Supreme Court's decision in United States v. Mead Corp., 533 U.S. 218, 121 S. Ct. 2164, 150 L. Ed. 2d 292 (2001), held that Chevron deference is confined to those instances in which the agency renders its interpretation in the course of a rulemaking proceeding or adjudication. Even so, most courts would not completely ignore an agency's interpretation of its organic statutes—even if that interpretation is advanced in the course of litigation rather than a rulemaking or agency adjudication.

The EPA has long taken the litigating position that ACOs lack the status of law and are therefore not subject to pre-enforcement review. In Solar Turbines Inc. v. Seif, 879 F.2d 1073 (3d Cir.1989), for example, the EPA argued that the section 7603 compliance order at issue "merely state[d] EPA's position and [is] best analogized to a complaint." Id. at 1079.26 The EPA took a similar position in this case when it argued that TVA's first petition for review should be dismissed because ACOs have no legal effect and are thus not final agency actions: "The ACO ... is in the nature of an administrative `complaint.'" See EPA's Motion to Dismiss TVA's Petition for Review of the Nov. 1999 and May 2000 ACOs at 24. And again: "Courts have consistently held that, because they are not self-executing and instead compel action only upon enforcement by the EPA, compliance orders issued under environmental statutes such as the Clean Air Act and Clean Water Act are not `final' under the APA." Id. (citations omitted). And again: ACOs "do not impose legally binding rights or obligations on the part of their recipients" and they are "not considered `final' for purposes of judicial review...." Id. at 26. And again: "[A]bsent an enforcement action initiated by the EPA and a subsequent court order, the findings and conclusions in an administrative order have no operative effect." Id. at 27.

Had Congress wanted ACOs to have the force of law, it surely would have made them subject to judicial review. And had Congress wanted judicial review of ACOs, it surely would have required the EPA to create a record that would facilitate judicial review. But Congress clearly contemplated that ACOs would be issued without a record, and so there would be no way that a reviewing court could review the decision to issue an ACO. The existence of this fact belies the notion that Congress intended to enact a statute in which ACOs have the force of law.

One might respond to this observation by saying that this case does, in fact, have a record, and, in any event, courts are always free to remand for the creation of a record. See Harrison v. PPG Indus., Inc., 446 U.S. 578, 100 S. Ct. 1889, 64 L. Ed. 2d 525 (1980). But this retort misses the point, avoiding an argument based upon likely congressional intent and relying upon the particularities of one bizarre case. The point is this: Congress created a statutory scheme in which ACOs are issued without any sort of adjudication, and, accordingly, the EPA has never (until now) undertaken a proceeding that even marginally resembles an adjudication prior to the issuance of an ACO. Given this fact, did Congress really think that a violation of the terms of an unadjudicated ACO (which are 99.9% of them) could trigger civil and criminal penalties? If Congress intended that ACOs have the force of law, then Congress surely would have facilitated judicial review. Yet in almost every case, the EPA does not go about making a record, and the statute clearly countenances this result. The impossibility of judicial review in this setting demonstrates the unlikelihood that Congress ever believed that noncompliance with the terms of an ACO could trigger civil and criminal penalties.

We also wonder how a court of appeals could remand with instructions that the EPA conduct a pre-ACO adjudication since the statute clearly does not require that the EPA undertake an adjudication prior to the issuance of an ACO?27 Perhaps the court is supposed to issue a statement in its remand order that says the following: "Although the statute says that the EPA need not conduct a pre-ACO adjudication, we think that it should do so." A remand with instructions to adjudicate a dispute would, in effect, constitute an amendment to the statute by judicial fiat.28

Finally, we ask this question: assuming, arguendo, that (a) ACOs have the status of law and (b) a court can make the EPA conduct a pre-ACO adjudication, what would be the issue for the court of appeals on review of the pre-ACO adjudication? Throughout this appeal, the litigants have assumed that EPA's adjudication could be overturned if it proves to be "arbitrary [and] capricious or otherwise not in accordance with the law." See 5 U.S.C. § 706(2)(A). But ACOs are valid so long as (a) the EPA waits the requisite thirty days after a Notice of Violation is issued; (b) the EPA grants an "opportunity to confer" with the Administrator; and (c) the EPA issues an ACO "on the basis of any information available to the Administrator" that a regulated party has violated the CAA. See 42 U.S.C. § 7413(a). The only real inquiry is whether the Administrator possessed "any information" — a standard that is less rigorous than the "probable cause" standard found in the criminal law setting. And it is certainly less rigorous than traditional judicial review of agency adjudications under the APA. Whether the Administrator's facts are too thin to warrant an adjudicated finding that an SIP has, in fact, been violated is irrelevant as far as ACOs are concerned. We therefore take issue with the notion that the courts of appeals are free to remand for an agency adjudication of whether an SIP has been violated when that issue is irrelevant in the ACO context.

The legislative history of the CAA, when read in conjunction with several cases that form the backdrop to that history, supports the notion that Congress did not believe that the issuance of an ACO constitutes final agency action. And since ACOs with the status of law must be final, it seems unlikely that Congress intended that ACOs have the status of law.

Prior to the CAA's enactment in 1970, the bill reported by the Senate Committee on Public Works, S. 4358, 91st Cong. (2d Sess.1970), contained section 116(a) — a provision that directed the Administrator to issue an abatement order to any person in violation of an SIP not being enforced by the state. The Senate measure also contained language that specifically provided for pre-enforcement judicial review of abatement orders. By the time the measure emerged from the Conference Committee, section 113 of the Act contained no language on the subject of pre-enforcement review. Drawing upon this "silent deletion," the Eighth Circuit held that Congress intended to preclude pre-enforcement review of ACOs. See Lloyd A. Fry Roofing Co. v. EPA, 554 F.2d 885, 890-91 (8th Cir.1977).29 The Eighth Circuit also noted that pre-enforcement judicial review would be "wholly inconsistent with the enforcement mechanism established by Congress" because "[p]re-enforcement review would severely limit the effectiveness of the conference procedure [provided by section 7413(a)(4)] as a means to abate violations of the Act without resort to judicial process." Id. The court rejected the interpretation proffered by the regulated party, because that interpretation would allow the EPA to "easily sidestep the possibility of pre-enforcement review by filing suit in the district court without prior issuance of an order...." Id. at 891. In other words, allowing pre-enforcement judicial review would create an enormous incentive for the EPA to head straight to federal court rather than using the alternative dispute resolution mechanism established by Congress. Why issue an ACO when doing so would enable the regulated party to file a petition for review and delay enforcement as long as possible? The EPA would be better off to hide its cards until it brings an enforcement action in federal court.

Other courts similarly concluded that pre-enforcement review is unavailable under the CAA. The Second Circuit, for example, considered a case highly analogous to the case at hand. See Asbestec Constr. Servs., Inc. v. EPA, 849 F.2d 765 (2d Cir.1988). Looking to the Supreme Court decision in FTC v. Standard Oil Co. of California, 449 U.S. 232, 239-43, 101 S. Ct. 488, 493-95, 66 L. Ed. 2d 416 (1980), for guidance, the Second Circuit held that the ACO was not a final agency action. The court conceded that the ACO was a final and definitive statement of the agency's position, but it believed that the other Standard Oil factors weighed against finding that the ACO was a final action. See Asbestec, 849 F.2d at 768. The court focused first on the second Standard Oil factor, which requires the reviewing court to analyze the effect on the petitioner absent review. The Second Circuit rejected Asbestec's claim that it would suffer adverse effects sufficient to deem the agency action final; it was not enough for Asbestec to show that it would be "stigmatized" or suffer "diminished opportunities" absent pre-enforcement review. Id. Relying on precedent, the court stated that "[the word] `effect' in determining whether an agency's action is final only denotes the imposition of an obligation, the denial of a right, or some other establishment of a legal relationship." Id. (citing Chicago & S. Air Lines, Inc. v. Waterman S.S. Corp., 333 U.S. 103, 112-13, 68 S. Ct. 431, 436-37, 92 L. Ed. 568 (1948), and Abbott Labs. v. Gardner, 387 U.S. 136, 152-53, 87 S. Ct. 1507, 1517-18, 18 L. Ed. 2d 681 (1967)). The court therefore held that "Asbestec's `stigma' contention ... is without merit because neither its duties nor its obligations have been altered by the compliance order." Id. at 768-69. The court then turned to the third Standard Oil factor and noted that the issues presented for review were not purely legal. Being mostly factual, "reviewing compliance orders would ordinarily place a significant burden on appellate courts." Id. at 769. The last Standard Oil factor — whether immediate judicial review would foster agency and judicial economy — similarly militated against finding that the compliance order was final. The court asserted that "the EPA must have some degree of free rein to protect the public from [environmental harm]. To introduce the delay of court review of administrative action taken to ameliorate a potential public health hazard would conflict with Congress' aim to `accelerate ... the prevention and control of air pollution.'" Id. (quoting 42 U.S.C. § 7401(b)(2)). The court thus concluded that "immediate pre-enforcement review of compliance orders... serve[s] neither efficiency nor enforcement of the Clean Air Act." Id.

The Third Circuit also held that pre-enforcement review of ACOs is not available under the CAA. See Solar Turbines Inc. v. EPA, 879 F.2d 1073 (3d Cir.1989). There, the EPA issued an ACO that "requir[ed] the immediate cessation of construction and/or operation of the gas turbine facility at Caterpillar Tractor." Id. at 1076. The court, approving of the reasoning of the Eighth Circuit and a prior Third Circuit opinion,30 discussed the policy behind Congress's implicit decision to deny pre-enforcement review:

A challenge to [an ACO] would intrude on the procedural sequence created by Congress whereby parties receiving notice of noncompliance are first encouraged to resolve their problems with the states and with EPA in an informal, less costly manner. Judicial review becomes appropriate when the EPA, failing efforts at negotiation and compromise, takes steps at enforcement subjecting the facility to consequential penalties.

Id. at 1078.

When the 1990 amendments to the CAA were proposed, the Senate supported a bill with a provision exactly the opposite of the bill it supported in 1970. That is, the Senate proposed that the CAA explicitly provide that "orders issued pursuant to section 113(a) [and] section 167 ... are not `final' agency actions within the meaning of section 307(b)(1)." S. Rep. 101-228 (Dec. 20, 1989). The Senate Report explained the policy behind the Senate proposal as one of (a) facilitating prompt EPA enforcement and (b) the promotion of judicial economy:

Any judicial review of administrative orders may be carried out only at the time the government or another person seeks to enforce such orders. Otherwise, enforcement for violations of the Act could be delayed indefinitely pending judicial review of the Federal courts of appeal. [Asbestec, Solar Turbines, Union Electric,31 and Lloyd A. Roofing] emphasize that this clarification comports with the goals of the Act. EPA must possess the ability to proceed expeditiously against violators. Allowing immediate review of an administrative order in a court of appeals would significantly delay enforcement, and could suspend correction of the underlying violation for years. This is particularly true in cases where a district court defers a decision pending a ruling by the court of appeals. Equally undesirable is the prospect that courts at both the district and court of appeals levels might decide to consider the same issue at the same time. In short, delays resulting from the pre-enforcement review of administrative orders not only conflict with the statutory directive that air pollution be prevented in an expeditious fashion, but it also hinders the ability to protect the public from the environmental hazards associated with air pollution.

* * *

This amendment will also promote judicial economy. At present, burdens on the Federal appellate courts are significant. Given the fact that many challenges to administrative orders involved factual questions, district court review in an enforcement proceeding is the better forum than is review in the court of appeals.

See S. Rep. 101-228 (Dec. 20, 1989).

Although the Conference Committee ultimately did not adopt the Senate proposal, it is not possible to draw the same inference from the "noisy" deletion in 1990 as one could draw about the "silent" deletion in 1970. By 1990, a legal backdrop had been created by judicial decisions holding that the CAA already precluded pre-enforcement review. Citing Asbestec, Solar Turbines, Union Electric, and Lloyd A. Fry Roofing, the Senate Report noted that "several courts" had already held that pre-enforcement review was foreclosed. For this reason, the Report described the amendment as a provision designed to "clarify" and "confirm" that ACOs were not subject to pre-enforcement review. The Senate sought only to make more clear what had already been established in judicial decisions. In a similar vein, two Senate managers on the Conference Committee for the 1990 CAA amendments explained the reasoning behind the Conference Committee's deletion as follows:

The conference agreement adopts the House provision. Section 307(b)(1) of the Act grants jurisdiction to the federal circuit courts of appeal to review "final action" of the administrator. The term "final action," however, is defined only by a non-exclusive list of particular kinds of actions. Several courts have specifically considered whether section 307(b)(1) provides for pre-enforcement review of administrative orders. As noted in Sen. Rep. 101-228, at 387, the Second, Third, and Eighth Circuits have already resolved and this issue and, as such, except with respect to judicial review of administrative penalty assessments and orders, there is no opportunity for pre-enforcement review and no new statutory language addressing the issue is necessary.

See Chafee-Baucus Statement of Senate Managers on the House-Senate Conference Agreement, 136 Cong. Rec. 36,085 (1990). Congress thus decided that the pre-1990 version of the CAA already precluded pre-enforcement review, making it unnecessary to "clarify" its intention to preclude pre-enforcement review in the 1990 amendments.

IV. Discussion of Finality, Part Three: Why the Plain Language of the CAA Does, in Fact, Give ACOs the Status of Law

We have at our disposal several tools that might guide our interpretation of the CAA: the constitutional avoidance canon, statutory structure, legislative history, agency practice, and the problem of judicial review. Even so, no canon of statutory interpretation can trump the unambiguous language of a statute. As part I.A, supra, makes clear, several provisions of the CAA undeniably authorize the imposition of severe civil and criminal penalties based solely upon noncompliance with an ACO.32 Although the Supreme Court has never addressed the precise meaning of 42 42 U.S.C. § 7413, it described the scheme as follows:

The 1970 amendments also specified certain enforcement mechanisms. The Act empowered EPA to order compliance with an applicable implementation plan, § 113(a), 42 U.S.C. § 7413(a) (1982 ed.), and to seek injunctive relief against a source violating the plan or an EPA order, § 113(b), as amended, 42 U.S.C. § 7413(b) (1982 ed.). In addition, Congress prescribed criminal penalties for knowing violations of plans and orders, § 113(c), 42 U.S.C. § 7413(c) (1982 ed.).

Gen. Motors Corp. v. United States, 496 U.S. 530, 533-34, 110 S. Ct. 2528, 2530, 110 L. Ed. 2d 480 (1990). Thus, the Court is apparently under the impression that the plain language of the CAA speaks for itself: noncompliance with an ACO can trigger civil and criminal penalties.

In a similar vein, a leading treatise concludes that "[f]ailure to comply with [an ACO] is [an] independent violation under [the CAA]." See Law of Environmental Protection § 9.22 (Sheldon M. Novick et al. eds., 2003). At least one law review article has made a similar assessment. See Andrew I. Davis, Judicial Review of Environmental Compliance Orders, 24 Envtl. L. 189, 194 (1994) ("Regardless of the merits of the alleged violation underlying the compliance order, disregarding the order potentially subjects the recipient to accruing daily penalties. In addition, criminal penalties may be imposed.... Thus, failure to obey a compliance order subjects the recipient to civil, criminal, or administrative enforcement actions, including penalties of up to $25,000 per day.").

Thus, although there are very good reasons for concluding that Congress did not mean what it said, the unambiguous language of the CAA, a decision by the Supreme Court, and scholarly commentary on the subject stand united in their support of the following proposition: Congress established a scheme in which noncompliance with an ACO issued "on the basis of any information available" can lead to the imposition of severe civil penalties and imprisonment — even if the EPA is incapable of proving an act of illegal pollution in court.

V. The Unconstitutionality of ACOs That Have the Status of Law

No court has discussed the constitutional issues inherent in a scheme in which an executive branch agency can (a) make a finding, on the basis of "any information available," that the law has been violated and (b) issue a compliance order which, if ignored, leads automatically to the imposition of severe civil penalties and perhaps imprisonment.

The cases that have addressed the issue of whether pre-enforcement review of ACOs is available33 can be grouped into two categories. The first category consists of those cases in which the courts recognize the fact that ACOs have the status of law but fail to grapple with the constitutional problems that arise from this legal status. These cases include Allsteel, Inc. v. EPA, 25 F.3d 312 (6th Cir.1994), and Alaska v. EPA, 244 F.3d 748 (9th Cir.2001) — the only two cases that have, to our knowledge, ever held that judicial review of an EPA order under the CAA or CWA can be had prior to an EPA enforcement proceeding.34

The second category consists of those cases in which courts have underappreciated the legal significance of ACOs. This category can, in turn, be divided into two subgroups. The first subgroup consists of cases in which courts conclude that a regulated party can attack, in a subsequent enforcement proceeding, the legal and factual bases for the EPA's conclusion that a CAA violation has been committed.35 See, e.g., Lloyd A. Fry Roofing Co. v. EPA, 554 F.2d 885, 891 (8th Cir.1977) ("[W]e are persuaded by the legislative history of the Clean Air Act Amendments of 1970 to hold that plaintiff lacks authority to initiate and maintain litigation to challenge the EPA's order ... and that plaintiff must assert its claims as a defense or counterclaim in any action brought by the Administrator of EPA under section 113 of the Clean Air Act."); Child v. United States, 851 F. Supp. 1527, 1536 (D.Utah 1994) ("[I]n the event of any actual assessment of administrative penalties or a judicial enforcement action under § 309(a), Plaintiffs would have an additional opportunity to challenge the EPA's findings in the district court."). If this view were correct, then the underlying conduct that triggered the issuance of the ACO would be the ultimate basis for liability, not noncompliance with the ACO. The ACO would fix no legal obligation whatsoever. Any judicial manipulation of the statute that would permit, in the context of an EPA enforcement suit alleging a violation of an ACO, an inquiry into the underlying violation — i.e., whether the alleged polluter actually undertook a "modification" without a permit or otherwise violated an SIP or EPA regulation — would have the effect of making the ACO nonfinal.36 Only if noncompliance with the terms of an ACO amounts to an independent violation of the CAA (thus triggering civil penalties and criminal sanctions) can an ACO be said to have a "legal consequence." And only then can an ACO be considered final. It is not surprising that no court in this subgroup has found that ACOs constitute final agency action.

The second subcategory consists of those cases in which courts read out the penalty provisions of the statutory scheme. In Solar Turbines, Inc. v. Seif, 879 F.2d 1073, 1081 (3d Cir.1989), the court held that "[t]he plain language of the statute does not identify any adverse consequences from violating a section 167 administrative order." However, as several commentators have observed, 42 U.S.C. § 7413(c)(1) provides that a violation of an order issued pursuant to CAA § 167, 42 U.S.C. § 7477, is a crime. See Law of Environmental Protection § 9.22 (Sheldon M. Novick et al. eds., 2003); Andre I. Davis, Judicial Review of Environmental Compliance Orders, 24 Envtl. L. 189, 220 (1994). This faulty premise enabled the Third Circuit to conclude that the ACO was merely a complaint-like instrument with no legal significance. Solar Turbines, 879 F.2d at 1081.37 The court in Asbestec Construction Services, Inc. v. EPA, 849 F.2d 765 (2d Cir.1988), similarly concluded that the regulated party failed to show that "its duties [or] obligations have been altered by the compliance order." Id. at 769. Finally, the court in Southern Pines Associates v. United States, 912 F.2d 713 (4th Cir.1990), held that the ACO issued pursuant to the CWA was nonfinal. The court based its conclusion not simply on the fact that the CWA was modeled after the CAA and therefore "Congress meant to preclude judicial review of compliance orders under the CWA just as it meant to preclude pre-enforcement review under the CAA and CERCLA." Id. at 716. Rather, the court also held a misguided understanding of the legal status of ACOs: "Because the compliance order does not alter [the regulated parties'] obligations under the Act, and EPA can bring a suit whether or not it issues an order, [the regulated parties] are not faced with any greater threat from EPA just because EPA seeks to negotiate a solution rather than to institute civil proceedings immediately." Id. at 716 n. 3.

The statutory scheme established by Congress — in which the head of an executive branch agency has the power to issue an order that has the status of law after finding, "on the basis of any information available," that a CAA violation has been committed — is repugnant to the Due Process Clause of the Fifth Amendment.38 Before the Government can impose severe civil and criminal penalties, the defendant is entitled to a full and fair hearing before an impartial tribunal "at a meaningful time and in a meaningful manner." Armstrong v. Manzo, 380 U.S. 545, 552, 85 S. Ct. 1187, 1191, 14 L. Ed. 2d 62 (1965). As shown in Scenario One, see supra part I.A, the scheme enacted by Congress deprives the regulated party of a "reasonable opportunity to be heard and present evidence"39 on the two most crucial issues: (a) whether the conduct underlying the issuance of the ACO actually took place and (b) whether the alleged conduct amounts to a CAA violation.

Confronted with this patent violation of the Due Process Clause, the EPA might be inclined to respond that it can always "save" the statute by voluntarily undertaking an adjudication prior to the issuance of an ACO. This is a fallacious argument, because the statute clearly establishes a scheme in which the decision to issue an ACO, like the decision to file a civil suit in district court, is made not after a full-blown adjudication of whether a CAA violation has been committed, but rather on the "basis of any information available to the Administrator." This is not an area in which the organic statute has set a vague standard, and there is simply no room for administrative discretion on this point. The EPA cannot, in short, amend the statute.

Far from rendering the statutory scheme more palatable, a pre-ACO adjudication would only highlight another constitutional problem with the CAA: the statutory scheme unconstitutionally delegates judicial power to a non-Article III tribunal. See N. Pipeline Constr. Co. v. Marathon Pipe Line Co., 458 U.S. 50, 102 S. Ct. 2858, 73 L. Ed. 2d 598 (1982). The statutory scheme relegates Article III courts to insignificant tribunals. The district courts serve as forums for the EPA to conduct show-cause hearings.40 And the courts of appeals are similarly emasculated, reviewing only whether the ACO has been validly issued — i.e., whether the Administrator based her decision to issue the ACO based upon "any information" as opposed to no information at all.41 Without meaningful judicial review, the scheme works an unconstitutional delegation of judicial power. See Crowell v. Benson, 285 U.S. 22, 55-60, 52 S. Ct. 285, 293-97, 76 L. Ed. 598 (1932) (upholding the plenary power of an administrative agency to adjudicate certain questions of fact because significant Article III review of legal and factual issues was preserved); Northern Pipeline, 458 U.S. at 85, 102 S. Ct. at 2879 (holding that Article III review of the bankruptcy court under the "clearly erroneous" standard was not rigorous enough to save the statute); id. at 70 n. 23, 102 S. Ct. at 2871 n. 23 (noting that "[even] when Congress assigns [`public rights'] matters to administrative agencies, or to legislative courts, it has generally provided, and we have suggested it may be required to provide, for Article III judicial review"); id. at 91, 102 S. Ct. at 2882 (Rehnquist, J., concurring) (agreeing with the plurality that the scope of judicial review established by the statute was insufficient to save the statute); id. at 115, 102 S. Ct. at 2894 (White, J., dissenting) (opining that appellate review "will go a long way toward insuring a proper separation of powers"); Commodity Futures Trading Comm'n v. Schor, 478 U.S. 833, 853, 106 S. Ct. 3245, 3258, 92 L. Ed. 2d 675 (1986) (upholding a CFTC adjudicatory scheme after noting that Congress permitted meaningful judicial review); see also Richard H. Fallon, Of Legislative Courts, Administrative Agencies, and Article III, 101 Harv. L.Rev. 916 (1988) (concluding that meaningful judicial review in an Article III court is a necessary and sufficient requirement under the Constitution); Richard B. Saphire & Michael E. Solimine, Shoring Up Article III: Legislative Court Doctrine in the Post CFTC v. Schor Era, 68 B.U. L.Rev. 85 (1988) (asserting that judicial review by an Article III court is a necessary but insufficient requirement of any delegation of judicial power).

The Clean Air Act is unconstitutional to the extent that mere noncompliance with the terms of an ACO can be the sole basis for the imposition of severe civil and criminal penalties. Therefore, ACOs lack finality because they do not meet prong two of the Bennett test. We thus conclude that courts of appeals lack jurisdiction to review the validity of ACOs. The EPA must do what it believes it has been required to do all along — namely, prove the existence of a CAA violation in district court, including the alleged violation that spurred the EPA to issue the ACO in this case.

PETITIONS DISMISSED.

BARKETT, Circuit Judge, specially concurring, WILSON, Circuit Judge, joins:

Upon reconsideration, I agree with Judge Tjoflat that this court does not have jurisdiction to review the EAB's order and that, to enforce its determination that TVA has violated the Clean Air Act, 42 U.S.C. § 7401 et seq., the appropriate procedure is for the EPA to file an original action in the district court, just as it does in most other instances in which it has determined that a violation has occurred. See 42 U.S.C. § 7413(b) (describing civil judicial enforcement); see also Second Brief of Respondents at 9 (explaining the EPA's normal course of action for enforcing a compliance order).

As Judge Tjoflat notes, 42 U.S.C. §§ 7413(a)(1), (3) and (5) each provide that the Administrator can conclude that there has been a violation of the requirements or prohibitions of the Clean Air Act "on the basis of any information." Id.; see also 42 U.S.C. § 7413(a)(2) (omitting the word "any" from comparable language in the provision concerning "State failure to enforce SIP or permit program"). Having concluded "on the basis of any information" that a violation has occurred, the Administrator can either:

(1) issue an order requiring compliance with the requirements or prohibitions at issue, 42 U.S.C. §§ 7413(a)(1)(A), (a)(2)(C) and (a)(3)(B), or prohibiting construction or modification, § 7413(a)(5)(A);

(2) obtain an administrative penalty order by following the hearing procedures of the Administrative Procedure Act, 5 U.S.C. § 554 and 556, see 42 U.S.C. §§ 7413(a)(1)(B), (a)(2)(B), (a)(3)(A), (a)(5)(B), and (d);

(3) bring a civil action in district court for injunctive relief and fines, §§ 7413(a)(1)(C), (a)(2)(C), (a)(3)(C), (a)(5)(C), and (b); and/or

(4) request that the Attorney General commence a criminal action, § 7413(a)(3)(D).

Under the statutory scheme, the first option for federal enforcement — issuing an administrative order, like the EAB's order before us — can be pursued based on "any information available," without giving the alleged violator an opportunity to challenge the information upon which the order of compliance is based. Although an alleged violator can "challenge" the Administrator's conclusion by conferring with him/her, the statute does not require that the Administrator consider any such arguments or evidence brought to his/her attention beyond that of a good faith effort to comply. See 42 U.S.C. § 7413(a)(4). Thereafter, the statutory scheme provides that penalties, either civil or criminal, can be assessed based only upon a showing that the terms of the order to comply were violated. See 42 U.S.C. § 7413(b)(2) (empowering the Administrator to commence a civil action for penalties against an alleged violator "whenever such person has violated, or is in violation of, ... a requirement or prohibition of any ... order ... issued ... under this chapter"); § 7413(c)(1) (subjecting any person convicted of "knowingly violating ... any order under subsection (a) of [§ 7413]" to criminal fines and/or imprisonment). This scheme must be deemed violative of the due process protections of our Constitution.

Although the Administrator in this case attempted to fill the gap in the statute and provide some process to TVA,1 it cannot be deemed sufficient because constitutional due process cannot be provided on an ad hoc basis under the direction and control of the entity whose decision is being challenged.2 The appropriate course of action, as noted by Judge Tjoflat, would have been for the EPA to file an action in federal district court pursuant to 42 U.S.C. § 7413(b) as it does in cases involving private energy companies. I recognize that the EPA believed that it could not have pursued this course of action against another government agency for the multitude of reasons presented and rejected in our earlier opinion in this case. However, as we have now laid all these concerns to rest, the EPA should treat TVA as it does any private energy company for enforcement purposes. Thus, the EPA's present recourse is to file an original action in federal district court to enforce its order that a violation has occurred.

§ 7413. Federal enforcement

(a) In general

(1) Order to comply with SIP

Whenever, on the basis of any information available to the Administrator, the Administrator finds that any person has violated or is in violation of any requirement or prohibition of an applicable implementation plan or permit, the Administrator shall notify the person and the State in which the plan applies of such finding. At any time after the expiration of 30 days following the date on which such notice of a violation is issued, the Administrator may, without regard to the period of violation (subject to section 2462 of title 28) —

(A) issue an order requiring such person to comply with the requirements or prohibitions of such plan or permit,

(B) issue an administrative penalty order in accordance with subsection (d) of this section, or

(C) bring a civil action in accordance with subsection (b) of this section.

(2) State failure to enforce SIP or permit program

Whenever, on the basis of information available to the Administrator, the Administrator finds that violations of an applicable implementation plan or an approved permit program under subchapter V of this chapter are so widespread that such violations appear to result from a failure of the State in which the plan or permit program applies to enforce the plan or permit program effectively, the Administrator shall so notify the State. In the case of a permit program, the notice shall be made in accordance with subchapter V of this chapter. If the Administrator finds such failure extends beyond the 30th day after such notice (90 days in the case of such permit program), the Administrator shall give public notice of such finding. During the period beginning with such public notice and ending when such State satisfies the Administrator that it will enforce such plan or permit program (hereafter referred to in this section as "period of federally assumed enforcement"), the Administrator may enforce any requirement or prohibition of such plan or permit program with respect to any person by —

(A) issuing an order requiring such person to comply with such requirement or prohibition,

(B) issuing an administrative penalty order in accordance with subsection (d) of this section, or

(C) bringing a civil action in accordance with subsection (b) of this section.

(3) EPA enforcement of other requirements

Except for a requirement or prohibition enforceable under the preceding provisions of this subsection, whenever, on the basis of any information available to the Administrator, the Administrator finds that any person has violated, or is in violation of, any other requirement or prohibition of this subchapter, section 7603 of this title, subchapter IV-A, subchapter V, or subchapter VI of this chapter, including, but not limited to, a requirement or prohibition of any rule, plan, order, waiver, or permit promulgated, issued, or approved under those provisions or subchapters, or for the payment of any fee owed to the United States under this chapter (other than subchapter II of this chapter), the Administrator may —

(A) issue an administrative penalty order in accordance with subsection (d) of this section,

(B) issue an order requiring such person to comply with such requirement or prohibition,

(C) bring a civil action in accordance with subsection (b) of this section or section 7605 of this title, or

(D) request the Attorney General to commence a criminal action in accordance with subsection (c) of this section.

(4) Requirements for orders

An order issued under this subsection (other than an order relating to a violation of section 7412 of this title) shall not take effect until the person to whom it is issued has had an opportunity to confer with the Administrator concerning the alleged violation. A copy of any order issued under this subsection shall be sent to the State air pollution control agency of any State in which the violation occurs. Any order issued under this subsection shall state with reasonable specificity the nature of the violation and specify a time for compliance which the Administrator determines is reasonable, taking into account the seriousness of the violation and any good faith efforts to comply with applicable requirements. In any case in which an order under this subsection (or notice to a violator under paragraph (1)) is issued to a corporation, a copy of such order (or notice) shall be issued to appropriate corporate officers. An order issued under this subsection shall require the person to whom it was issued to comply with the requirement as expeditiously as practicable, but in no event longer than one year after the date the order was issued, and shall be nonrenewable. No order issued under this subsection shall prevent the State or the Administrator from assessing any penalties nor otherwise affect or limit the State's or the United States authority to enforce under other provisions of this chapter, nor affect any person's obligations to comply with any section of this chapter or with a term or condition of any permit or applicable implementation plan promulgated or approved under this chapter.

(5) Failure to comply with new source requirements

Whenever, on the basis of any available information, the Administrator finds that a State is not acting in compliance with any requirement or prohibition of the chapter relating to the construction of new sources or the modification of existing sources, the Administrator may —

(A) issue an order prohibiting the construction or modification of any major stationary source in any area to which such requirement applies;1

(B) issue an administrative penalty order in accordance with subsection (d) of this section, or

(C) bring a civil action under subsection (b) of this section.

Nothing in this subsection shall preclude the United States from commencing a criminal action under subsection (c) of this section at any time for any such violation.

(b) Civil judicial enforcement

The Administrator shall, as appropriate, in the case of any person that is the owner or operator of an affected source, a major emitting facility, or a major stationary source, and may, in the case of any other person, commence a civil action for a permanent or temporary injunction, or to assess and recover a civil penalty of not more than $25,000 per day for each violation, or both, in any of the following instances:

(1) Whenever such person has violated, or is in violation of, any requirement or prohibition of an applicable implementation plan or permit. Such an action shall be commenced (A) during any period of federally assumed enforcement, or (B) more than 30 days following the date of the Administrator's notification under subsection (a)(1) of this section that such person has violated, or is in violation of, such requirement or prohibition.

(2) Whenever such person has violated, or is in violation of, any other requirement or prohibition of this subchapter, section 7603 of this title, subchapter IV-A, subchapter V, or subchapter VI of this chapter, including, but not limited to, a requirement or prohibition of any rule, order, waiver or permit promulgated, issued, or approved under this chapter, or for the payment of any fee owed the United States under this chapter (other than subchapter II of this chapter).

(3) Whenever such person attempts to construct or modify a major stationary source in any area with respect to which a finding under subsection (a)(5) of this section has been made.

Any action under this subsection may be brought in the district court of the United States for the district in which the violation is alleged to have occurred, or is occurring, or in which the defendant resides, or where the defendant's principal place of business is located, and such court shall have jurisdiction to restrain such violation, to require compliance, to assess such civil penalty, to collect any fees owed the United States under this chapter (other than subchapter II of this chapter) and any noncompliance assessment and nonpayment penalty owed under section 7420 of this title, and to award any other appropriate relief. Notice of the commencement of such action shall be given to the appropriate State air pollution control agency. In the case of any action brought by the Administrator under this subsection, the court may award costs of litigation (including reasonable attorney and expert witness fees) to the party or parties against whom such action was brought if the court finds that such action was unreasonable.

(c) Criminal penalties

(1) Any person who knowingly violates any requirement or prohibition of an applicable implementation plan (during any period of federally assumed enforcement or more than 30 days after having been notified under subsection (a)(1) of this section by the Administrator that such person is violating such requirement or prohibition), any order under subsection (a) of this section, requirement or prohibition of section 7411(e) of this title (relating to new source performance standards), section 7412 of this title, section 7414 of this title (relating to inspections, etc.), section 7429 of this title (relating to solid waste combustion), section 7475(a) of this title (relating to preconstruction requirements), an order under section 7477 of this title (relating to preconstruction requirements), an order under section 7603 of this title (relating to emergency orders), section 7661a(a) or 7661b(c) of this title (relating to permits), or any requirement or prohibition of subchapter IV-A of this chapter (relating to acid deposition control), or subchapter VI of this chapter (relating to stratospheric ozone control), including a requirement of any rule, order, waiver, or permit promulgated or approved under such sections or subchapters, and including any requirement for the payment of any fee owed the United States under this chapter (other than subchapter II of this chapter) shall, upon conviction, be punished by a fine pursuant to title 18 or by imprisonment for not to exceed 5 years, or both. If a conviction of any person under this paragraph is for a violation committed after a first conviction of such person under this paragraph, the maximum punishment shall be doubled with respect to both the fine and imprisonment.

(2) Any person who knowingly —

(A) makes any false material statement, representation, or certification in, or omits material information from, or knowingly alters, conceals, or fails to file or maintain any notice, application, record, report, plan, or other document required pursuant to this chapter to be either filed or maintained (whether with respect to the requirements imposed by the Administrator or by a State);

(B) fails to notify or report as required under this chapter; or

(C) falsifies, tampers with, renders inaccurate, or fails to install any monitoring device or method required to be maintained or followed under this chapter2

shall, upon conviction, be punished by a fine pursuant to title 18 or by imprisonment for not more than 2 years, or both. If a conviction of any person under this paragraph is for a violation committed after a first conviction of such person under this paragraph, the maximum punishment shall be doubled with respect to both the fine and imprisonment.

(3) Any person who knowingly fails to pay any fee owed the United States under this subchapter, subchapter III, IV-A, V, or VI of this chapter shall, upon conviction, be punished by a fine pursuant to title 18 or by imprisonment for not more than 1 year, or both. If a conviction of any person under this paragraph is for a violation committed after a first conviction of such person under this paragraph, the maximum punishment shall be doubled with respect to both the fine and imprisonment.

(4) Any person who negligently releases into the ambient air any hazardous air pollutant listed pursuant to section 7412 of this title or any extremely hazardous substance listed pursuant to section 11002(a)(2) of this title that is not listed in section 7412 of this title, and who at the time negligently places another person in imminent danger of death or serious bodily injury shall, upon conviction, be punished by a fine under title 18 or by imprisonment for not more than 1 year, or both. If a conviction of any person under this paragraph is for a violation committed after a first conviction of such person under this paragraph, the maximum punishment shall be doubled with respect to both the fine and imprisonment.

(5)(A) Any person who knowingly releases into the ambient air any hazardous air pollutant listed pursuant to section 7412 of this title or any extremely hazardous substance listed pursuant to section 11002(a)(2) of this title that is not listed in section 7412 of this title, and who knows at the time that he thereby places another person in imminent danger of death or serious bodily injury shall, upon conviction, be punished by a fine under title 18 or by imprisonment of not more than 15 years, or both. Any person committing such violation which is an organization shall, upon conviction under this paragraph, be subject to a fine of not more than $1,000,000 for each violation. If a conviction of any person under this paragraph is for a violation committed after a first conviction of such person under this paragraph, the maximum punishment shall be doubled with respect to both the fine and imprisonment. For any air pollutant for which the Administrator has set an emissions standard or for any source for which a permit has been issued under subchapter V of this chapter, a release of such pollutant in accordance with that standard or permit shall not constitute a violation of this paragraph or paragraph (4).

(B) In determining whether a defendant who is an individual knew that the violation placed another person in imminent danger of death or serious bodily injury —

(i) the defendant is responsible only for actual awareness or actual belief possessed; and

(ii) knowledge possessed by a person other than the defendant, but not by the defendant, may not be attributed to the defendant;

except that in proving a defendant's possession of actual knowledge, circumstantial evidence may be used, including evidence that the defendant took affirmative steps to be shielded from relevant information.

(C) It is an affirmative defense to a prosecution that the conduct charged was freely consented to by the person endangered and that the danger and conduct charged were reasonably foreseeable hazards of —

(i) an occupation, a business, or a profession; or

(ii) medical treatment or medical or scientific experimentation conducted by professionally approved methods and such other person had been made aware of the risks involved prior to giving consent.

The defendant may establish an affirmative defense under this subparagraph by a preponderance of the evidence.

(D) All general defenses, affirmative defenses, and bars to prosecution that may apply with respect to other Federal criminal offenses may apply under subparagraph (A) of this paragraph and shall be determined by the courts of the United States according to the principles of common law as they may be interpreted in the light of reason and experience. Concepts of justification and excuse applicable under this section may be developed in the light of reason and experience.

(E) The term "organization" means a legal entity, other than a government, established or organized for any purpose, and such term includes a corporation, company, association, firm, partnership, joint stock company, foundation, institution, trust, society, union, or any other association of persons.

(F) The term "serious bodily injury" means bodily injury which involves a substantial risk of death, unconsciousness, extreme physical pain, protracted and obvious disfigurement or protracted loss or impairment of the function of a bodily member, organ, or mental faculty.

(6) For the purpose of this subsection, the term "person" includes, in addition to the entities referred to in section 7602(e) of this title, any responsible corporate officer.

(d) Administrative assessment of civil penalties

(1) The Administrator may issue an administrative order against any person assessing a civil administrative penalty of up to $25,000, per day of violation, whenever, on the basis of any available information, the Administrator finds that such person —

(A) has violated or is violating any requirement or prohibition of an applicable implementation plan (such order shall be issued (i) during any period of federally assumed enforcement, or (ii) more than thirty days following the date of the Administrator's notification under subsection (a)(1) of this section of a finding that such person has violated or is violating such requirement or prohibition); or

(B) has violated or is violating any other requirement or prohibition of this subchapter or subchapter III, IV-A, V, or VI of this chapter, including, but not limited to, a requirement or prohibition of any rule, order, waiver, permit, or plan promulgated, issued, or approved under this chapter, or for the payment of any fee owed the United States under this chapter (other than subchapter II of this chapter); or

(C) attempts to construct or modify a major stationary source in any area with respect to which a finding under subsection (a)(5) of this section has been made.

The Administrator's authority under this paragraph shall be limited to matters where the total penalty sought does not exceed $200,000 and the first alleged date of violation occurred no more than 12 months prior to the initiation of the administrative action, except where the Administrator and the Attorney General jointly determine that a matter involving a larger penalty amount or longer period of violation is appropriate for administrative penalty action. Any such determination by the Administrator and the Attorney General shall not be subject to judicial review.

(2)(A) An administrative penalty assessed under paragraph (1) shall be assessed by the Administrator by an order made after opportunity for a hearing on the record in accordance with sections 554 and 556 of title 5. The Administrator shall issue reasonable rules for discovery and other procedures for hearings under this paragraph. Before issuing such an order, the Administrator shall give written notice to the person to be assessed an administrative penalty of the Administrator's proposal to issue such order and provide such person an opportunity to request such a hearing on the order, within 30 days of the date the notice is received by such person.

(B) The Administrator may compromise, modify, or remit, with or without conditions, any administrative penalty which may be imposed under this subsection.

(3) The Administrator may implement, after consultation with the Attorney General and the States, a field citation program through regulations establishing appropriate minor violations for which field citations assessing civil penalties not to exceed $5,000 per day of violation may be issued by officers or employees designated by the Administrator. Any person to whom a field citation is assessed may, within a reasonable time as prescribed by the Administrator through regulation, elect to pay the penalty assessment or to request a hearing on the field citation. If a request for a hearing is not made within the time specified in the regulation, the penalty assessment in the field citation shall be final. Such hearing shall not be subject to section 554 or 556 of title 5, but shall provide a reasonable opportunity to be heard and to present evidence. Payment of a civil penalty required by a field citation shall not be a defense to further enforcement by the United States or a State to correct a violation, or to assess the statutory maximum penalty pursuant to other authorities in the chapter, if the violation continues.

(4) Any person against whom a civil penalty is assessed under paragraph (3) of this subsection or to whom an administrative penalty order is issued under paragraph (1) of this subsection may seek review of such assessment in the United States District Court for the District of Columbia or for the district in which the violation is alleged to have occurred, in which such person resides, or where such person's principal place of business is located, by filing in such court within 30 days following the date the administrative penalty order becomes final under paragraph (2), the assessment becomes final under paragraph (3), or a final decision following a hearing under paragraph (3) is rendered, and by simultaneously sending a copy of the filing by certified mail to the Administrator and the Attorney General. Within 30 days thereafter, the Administrator shall file in such court a certified copy, or certified index, as appropriate, of the record on which the administrative penalty order or assessment was issued. Such court shall not set aside or remand such order or assessment unless there is not substantial evidence in the record, taken as a whole, to support the finding of a violation or unless the order or penalty assessment constitutes an abuse of discretion. Such order or penalty assessment shall not be subject to review by any court except as provided in this paragraph. In any such proceedings, the United States may seek to recover civil penalties ordered or assessed under this section.

(5) If any person fails to pay an assessment of a civil penalty or fails to comply with an administrative penalty order —

(A) after the order or assessment has become final, or

(B) after a court in an action brought under paragraph (4) has entered a final judgment in favor of the Administrator,

the Administrator shall request the Attorney General to bring a civil action in an appropriate district court to enforce the order or to recover the amount ordered or assessed (plus interest at rates established pursuant to section 6621(a)(2) of title 26 from the date of the final order or decision or the date of the final judgment, as the case may be). In such an action, the validity, amount, and appropriateness of such order or assessment shall not be subject to review. Any person who fails to pay on a timely basis a civil penalty ordered or assessed under this section shall be required to pay, in addition to such penalty and interest, the United States enforcement expenses, including but not limited to attorneys fees and costs incurred by the United States for collection proceedings and a quarterly nonpayment penalty for each quarter during which such failure to pay persists. Such nonpayment penalty shall be 10 percent of the aggregate amount of such person's outstanding penalties and nonpayment penalties accrued as of the beginning of such quarter.

(e) Penalty assessment criteria

(1) In determining the amount of any penalty to be assessed under this section or section 7604(a) of this title, the Administrator or the court, as appropriate, shall take into consideration (in addition to such other factors as justice may require) the size of the business, the economic impact of the penalty on the business, the violator's full compliance history and good faith efforts to comply, the duration of the violation as established by any credible evidence (including evidence other than the applicable test method), payment by the violator of penalties previously assessed for the same violation, the economic benefit of noncompliance, and the seriousness of the violation. The court shall not assess penalties for noncompliance with administrative subpoenas under section 7607(a) of this title, or actions under section 7414 of this title, where the violator had sufficient cause to violate or fail or refuse to comply with such subpoena or action.

(2) A penalty may be assessed for each day of violation. For purposes of determining the number of days of violation for which a penalty may be assessed under subsection (b) or (d)(1) of this section, or section 7604(a) of this title, or an assessment may be made under section 7420 of this title, where the Administrator or an air pollution control agency has notified the source of the violation, and the plaintiff makes a prima facie showing that the conduct or events giving rise to the violation are likely to have continued or recurred past the date of notice, the days of violation shall be presumed to include the date of such notice and each and every day thereafter until the violator establishes that continuous compliance has been achieved, except to the extent that the violator can prove by a preponderance of the evidence that there were intervening days during which no violation occurred or that the violation was not continuing in nature.

(f) Awards

The Administrator may pay an award, not to exceed $10,000, to any person who furnishes information or services which lead to a criminal conviction or a judicial or administrative civil penalty for any violation of this subchapter or subchapter III, IV-A, V, or VI of this chapter enforced under this section. Such payment is subject to available appropriations for such purposes as provided in annual appropriation Acts. Any officer, or employee of the United States or any State or local government who furnishes information or renders service in the performance of an official duty is ineligible for payment under this subsection. The Administrator may, by regulation, prescribe additional criteria for eligibility for such an award.

(g) Settlements; public participation

At least 30 days before a consent order or settlement agreement of any kind under this chapter to which the United States is a party (other than enforcement actions under this section, section 7420 of this title, or subchapter II of this chapter, whether or not involving civil or criminal penalties, or judgments subject to Department of Justice policy on public participation) is final or filed with a court, the Administrator shall provide a reasonable opportunity by notice in the Federal Register to persons who are not named as parties or intervenors to the action or matter to comment in writing. The Administrator or the Attorney General, as appropriate, shall promptly consider any such written comments and may withdraw or withhold his consent to the proposed order or agreement if the comments disclose facts or considerations which indicate that such consent is inappropriate, improper, inadequate, or inconsistent with the requirements of this chapter. Nothing in this subsection shall apply to civil or criminal penalties under this chapter.

(h) Operator

For purposes of the provisions of this section and section 7420 of this title, the term "operator", as used in such provisions, shall include any person who is senior management personnel or a corporate officer. Except in the case of knowing and willful violations, such term shall not include any person who is a stationary engineer or technician responsible for the operation, maintenance, repair, or monitoring of equipment and facilities and who often has supervisory and training duties but who is not senior management personnel or a corporate officer. Except in the case of knowing and willful violations, for purposes of subsection (c)(4) of this section, the term "a person" shall not include an employee who is carrying out his normal activities and who is not a part of senior management personnel or a corporate officer. Except in the case of knowing and willful violations, for purposes of paragraphs (1), (2), (3), and (5) of subsection (c) of this section the term "a person" shall not include an employee who is carrying out his normal activities and who is acting under orders from the employer.

§ 7477. Enforcement

The Administrator shall, and a State may, take such measures, including issuance of an order, or seeking injunctive relief, as necessary to prevent the construction or modification of a major emitting facility which does not conform to the requirements of this part, or which is proposed to be constructed in any area designated pursuant to section 7407(d) of this title as attainment or unclassifiable and which is not subject to an implementation plan which meets the requirements of this part.
