Section 109(a) of the Clean Air Act (CAA) mandates the EPA Administrator to establish national ambient air quality standards (NAAQS) for pollutants with issued air quality criteria. In 1997, the Administrator revised the ozone and particulate matter NAAQS, prompting a challenge from private parties and several states. The D.C. Circuit Court found that the Administrator's interpretation of Section 109(b)(1), which directs the EPA to set standards necessary to protect public health with an adequate margin of safety, improperly delegated legislative power, violating constitutional principles. The court ruled that the EPA cannot consider implementation costs in setting NAAQS, as the CAA explicitly allows cost considerations in other contexts but not in this provision. The court also concluded that the implementation provisions for ozone NAAQS did not impede the EPA's authority to revise the standards. The Supreme Court held that Section 109(b)(1) does not authorize the consideration of implementation costs, emphasizing that Congress does not delegate such authority through vague language. Additionally, the court determined that Section 109(b)(1) does not represent a delegation of legislative power to the EPA, as Congress must provide a clear principle for agency action.

An agency is unable to remedy an unlawful delegation of legislative power merely by adopting a limiting interpretation of a statute. The limitations imposed by section 109(b)(1) on the EPA's discretion closely resemble those upheld in previous cases, such as Touby v. United States. Additionally, the scope of discretion permitted by this section is consistent with established nondelegation precedents, like Panama Refining Co. v. Ryan. Statutes do not need to define a precise measure of regulated harm to avoid delegating legislative authority.

The Court of Appeals possessed jurisdiction to address the implementation issue under section 307 of the Clean Air Act (CAA). The implementation policy is considered final agency action as it represents the culmination of the EPA's decision-making process. This issue is ripe for review as it involves statutory interpretation that does not require further factual development, and reviewing it will not impede ongoing administrative processes. The hardship faced by states in creating implementation plans meets the CAA's criteria for preenforcement review. 

The implementation policy itself is deemed unlawful. According to Chevron U.S.A. Inc. v. Natural Resources Defense Council, if a statute clearly dictates whether Subpart 1 or Subpart 2 applies to revised ozone National Ambient Air Quality Standards (NAAQS), that should resolve the matter. If ambiguous, the Court typically defers to a reasonable agency interpretation. However, in this case, the statute's ambiguity concerning Subparts 1 and 2 prevents deference to the EPA's interpretation, which could undermine the restrictions imposed by Subpart 2 on EPA discretion after a new ozone NAAQS is established. Subpart 2 was intended to limit the regulatory discretion granted by Subpart 1. The EPA cannot interpret the statute in a manner that negates the explicit limitations designed to control its authority. While Subpart 2 was created for long-term governance, the EPA's interpretation could have allowed for its immediate withdrawal post-enactment. The EPA is tasked with developing a reasonable interpretation of nonattainment implementation provisions related to revised ozone NAAQS.

The final rulings involve affirming in part, reversing in part, and remanding the cases noted. The opinion of the Court by Justice Scalia included unanimous and partial agreements from various justices, with additional concurring opinions filed by Justices Thomas, Stevens, and Breyer.

Justice Scalia delivered the Court's opinion addressing four key legal questions concerning the Clean Air Act (CAA) and the authority of the Environmental Protection Agency (EPA). First, it was determined whether Section 109(b)(1) of the CAA delegates legislative power to the EPA Administrator. The Court of Appeals found this delegation unconstitutional due to a lack of an "intelligible principle" to guide the EPA, suggesting a restrictive interpretation could mitigate this issue. Second, the court unanimously upheld the EPA's position that it could not consider the costs of implementation when setting national ambient air quality standards (NAAQS), reaffirming precedent from Lead Industries Assn. Inc. v. EPA. Third, the Court of Appeals confirmed its jurisdiction to review the EPA's interpretation of Part D of Title I of the CAA regarding the revised ozone NAAQS, determining that while the implementation provisions constrained the EPA, they did not prevent it from revising standards. The EPA's petition for rehearing on these matters was denied, prompting the Administrator to seek Supreme Court review on the first, third, and fourth questions. Dissenting opinions were noted regarding the constitutionality of the delegation issue.

Respondents filed a conditional cross-petition for review regarding a specific question, leading to the Supreme Court granting certiorari on both petitions and consolidating the cases for decision. The D.C. Circuit previously ruled in Lead Industries Assn. Inc. v. EPA that economic considerations cannot influence the establishment of ambient air quality standards under Section 109 of the Clean Air Act (CAA). This ruling was reaffirmed in the present cases. Respondents challenged this interpretation but the court maintained its stance, emphasizing that the statute's language does not allow the EPA to factor in costs when setting health-based standards.

Section 109(b)(1) directs the EPA to establish primary ambient air quality standards necessary to protect public health with an adequate margin of safety, without considering costs. The court highlighted that the term "public health" in this context refers to the health of the community rather than a broader interpretation that includes economic impacts. Respondents contended that various factors, including economic costs, could affect public health outcomes, arguing that stringent standards might lead to negative health consequences by impacting industries and their workers. However, the court found these arguments unpersuasive, adhering to the clear statutory language regarding the EPA's responsibilities.

Congress acknowledged the potential economic impacts of air quality standards when it enacted the Air Quality Act of 1967, which included detailed studies on the costs of implementation and economic effects on industries and communities. The results informed the Clean Air Act (CAA) of 1970, where provisions were established to address compliance costs. Specifically, Section 110(f)(1) allowed the Administrator to waive compliance deadlines for stationary sources if control measures were unavailable and their operation was vital for public health. Other sections, such as 111(b)(1)(B) and 202(a)(2), required the Administrator to consider costs when setting performance standards and emissions regulations for new sources and automobiles, respectively. Subsequent amendments have consistently mandated that cost considerations be factored into regulatory decisions. The court has interpreted that implicit authorization for cost consideration cannot be inferred from ambiguous language within the CAA, emphasizing that Congress articulates substantial changes clearly rather than indirectly. To support their challenge, respondents must demonstrate a clear textual authority for the EPA to consider costs in establishing National Ambient Air Quality Standards (NAAQS) under Section 109(b)(1), as this section is pivotal to the CAA's framework. Their argument that terms like "adequate margin" and "requisite" in 109(b)(1) imply space for incorporating cost concerns is ultimately unconvincing.

Congress is unlikely to delegate significant regulatory decisions, such as the determination of implementation costs for national air quality standards, to an agency without explicit mention in the legislation. Previous cases underscore this perspective, with Justice Scalia emphasizing that ambiguity in legislation must be interpreted with caution regarding agency discretion. The arguments asserting that the Environmental Protection Agency (EPA) can consider costs when establishing health protection standards are flawed; costs are indirectly related to public health and should have been explicitly included in the relevant sections of the Clean Air Act (CAA) if intended for consideration. While certain CAA provisions require the generation of cost data to assist states in implementing the National Ambient Air Quality Standards (NAAQS), they do not imply that such costs should be factored into the standards themselves. The primary responsibility for determining emissions reductions rests with the states, and federal legislation has consistently directed agencies to provide implementation data, including costs, to aid states in this role.

Congress's decision to continue the research program to aid States in implementing standards does not imply that cost considerations should influence the formulation of air quality standards. The statutory interpretation of Section 109(b) of the Clean Air Act (CAA) clearly prohibits the inclusion of cost in the National Ambient Air Quality Standards (NAAQS) setting process, confirming the Court of Appeals' judgment on this matter. The CAA mandates that the Environmental Protection Agency (EPA) establish air quality standards necessary to protect public health based on scientific criteria, allowing for an adequate margin of safety. 

The Court of Appeals found that the EPA lacked a clear principle guiding its authority in setting NAAQS, leading to a violation of the nondelegation doctrine. However, this interpretation is contested. The delegation of legislative power to agencies must include an "intelligible principle" established by Congress, which cannot be rectified by the agency's discretionary limitations. The agency's decision on how to exercise its power does not address whether the delegation itself is unconstitutional. 

The interpretation of Section 109(b)(1) necessitates that the EPA set uniform national standards for specific pollutants reflecting the latest scientific knowledge, aimed at adequately protecting public health without exceeding necessary limits.

Limits on the EPA's discretion align with precedents such as Touby v. United States, which allowed the Attorney General to classify drugs as controlled substances to avert public safety hazards. Similarly, the Occupational Safety and Health Act mandates setting standards that, based on the best available evidence, prevent employee health impairments. The Court has recognized that only two statutes lacked an "intelligible principle" for discretion, one providing no guidance and the other allowing broad economic regulation without clear standards. In contrast, statutes like the Public Utility Holding Company Act and wartime price regulation have been upheld for providing adequate guidance. The Court has consistently refrained from second-guessing Congress on the extent of policy judgment permissible for agencies. While Congress does not need to direct the EPA on specific definitions, substantial guidance is required for setting air standards impacting the national economy. Despite broad regulatory frameworks, the Court has not mandated a "determinate criterion" for assessing regulated harms, as illustrated in Touby, where it did not specify thresholds for terms like "imminent" or "hazardous."

The statute referenced in Lichter allowed agencies to reclaim "excess profits" from wartime contracts without requiring Congress to define the threshold for excess profits, highlighting that a degree of discretion is inherent in executive and judicial actions. The argument that ozone and particulate matter are "nonthreshold" pollutants necessitating EPA judgment does not negate this discretion. Section 109(b)(1) of the Clean Air Act (CAA) mandates the EPA to establish air quality standards necessary to protect public health, which is within the permissible scope of discretion. The judgment of the Court of Appeals is reversed, and the case is remanded for further consideration of other challenges to the National Ambient Air Quality Standards (NAAQS) under judicial review provisions.

The document also addresses the EPA's authority to enforce the revised ozone NAAQS in areas classified as "nonattainment," which have ozone levels exceeding the standard. These areas are subject to additional restrictions under various CAA provisions. A key dispute is whether Subpart 1 or Subpart 2, or a combination of both, governs the implementation of the revised ozone NAAQS in nonattainment areas. The EPA contends that the Court of Appeals lacked jurisdiction to review its implementation policy, arguing that it was neither agency "action" nor "final." However, the court rejects these claims, noting that the EPA proposed an interim implementation policy alongside the revised NAAQS, which had undergone public comment and was further defined by a White House memorandum detailing implementation procedures.

The memorandum referenced in 62 Fed. Reg. 38421 (1997) is not considered an action by the EPA. The agency provided implementation procedures for new ozone National Ambient Air Quality Standards (NAAQS) in the explanatory preamble of its final decision. After reviewing comments on the Interim Implementation Policy, the EPA revised its interpretation, stating that provisions from "subpart 1 of part D of Title I of the Act" would immediately apply to the new 8-hour ozone standards. The old 1-hour standard will continue to be relevant until areas achieve compliance, after which "subpart 2" provisions will no longer apply.

This action constitutes final agency action subject to review under section 307 of the Clean Air Act (CAA), as it represents the culmination of the EPA's decision-making process—beginning with a 1996 proposal and concluding after public comment and a directive from the White House. The EPA's decision has not been reconsidered in subsequent rulemakings, indicating its finality despite lacking conventional procedural finality.

The issue is deemed ripe for judicial review, as it involves statutory interpretation that does not require further factual development or administrative action. There is also hardship for the respondent States, which must quickly create state implementation plans (SIPs) to meet the new standards, risking loss of control to the EPA if they fail to do so within five years. The situation is analyzed under the CAA's special judicial-review provisions.

The legal document addresses the concept of "preenforcement" review, allowing judicial review prior to the effects typically required under the Administrative Procedure Act (APA). The implementation issue regarding the ozone standard was included in the challenges presented to the Court of Appeals. Respondents argued that the EPA could not revise the ozone standard without triggering Subpart 1, which they claimed had been supplanted by Subpart 2. The EPA countered that Subpart 2 supplemented rather than supplanted Subpart 1, asserting that Subpart 1 still applied to all nonattainment areas, including those for revised ozone standards. The District of Columbia Circuit found that Subpart 2 could be harmonized with the EPA’s authority to revise National Ambient Air Quality Standards (NAAQS), but rejected the EPA’s claim that the court should have accepted its interpretation without assessing the agency's reasoning.

The court applied the Chevron framework, determining that if the statute clearly dictated which subpart should apply, that would resolve the matter. However, it found the statute ambiguous regarding the application of Subpart 1 or Subpart 2 to revised ozone NAAQS. The court deemed the EPA's interpretation exceeded the ambiguous nature of the statute and contradicted clear statutory provisions, thus ruling the agency's implementation policy unlawful. Specific sections of Subpart 1 indicate that if ozone area classifications are provided for elsewhere in the statute, those provisions take precedence over Subpart 1.

The substantive language of Subpart 1 allows for the application of revised ozone standards, as indicated in 7502(a)(1)(A), which mandates classification of nonattainment areas according to any revised standard, including those in effect on November 15, 1990. However, a critical question arises as to whether Subpart 2 governs the classification of ozone nonattainment areas under the revised standards. It does, as established by Table 1 in 7511(a)(1), which categorizes ozone nonattainment areas and sets attainment deadlines. Section 7511(a)(1) states that all nonattainment areas will be classified by operation of law at the time of designation, with deadlines to achieve primary standard attainment as soon as practicable, but no later than those outlined in Table 1.

The EPA's argument that 7511(a) is limited to nonattainment areas from 1989 is countered by 7511(b)(1), which clarifies that classification applies to areas that have moved from attainment to nonattainment after 1989, thus negating the interpretive weight of the title. While some provisions of Subpart 2 may not align well with the revised standards—such as its reliance on outdated 1-hour ozone averages—this does not diminish its applicability. Moreover, Subpart 2 does not adequately account for areas exceeding the new stricter ozone standard but falling below the old standard approximation defined in Table 1. Lastly, the method for calculating attainment dates is based on a fixed timeline from November 15, 1990, which may not effectively accommodate the nuances of revised standards.

The classification of areas under new ozone standards, particularly those designated after November 15, 1990, creates inconsistencies in the enforcement framework established by Subpart 2. For areas classified in 2000, many deadlines would have already lapsed, suggesting that Congress did not intend for Subpart 2 to be the sole, permanent method for enforcing revised ozone standards in nonattainment areas. The interaction between Subpart 1 and Subpart 2 regarding these standards is ambiguous, and while the EPA's interpretation of this ambiguity is entitled to deference, the agency's view that Subpart 2 becomes obsolete upon a new standard is not defensible.

Subpart 1 grants the EPA significant regulatory discretion in classifying nonattainment areas and extending attainment deadlines, whereas Subpart 2 imposes strict legal classifications and limits extensions to two years. The EPA's assertion that Subpart 2 was merely a transition for the old 1-hour standard and that the new 8-hour standards could be implemented under Subpart 1 fails to acknowledge Subpart 2's explicit applicability and the restrictions it imposes on EPA discretion. Additionally, provisions of Subpart 2 were designed for long-term implementation, with certain requirements not set to take effect until years after the Act's passage, indicating that the framework was not intended to be discarded with every review of ozone standards. The statutory requirement for a review and potential revision of the National Ambient Air Quality Standards (NAAQS) every five years underscores that Subpart 2 was crafted with a long-term perspective.

The EPA's interpretation allows for the possibility of abandoning Subpart 2 immediately after its enactment and does not prevent certain areas from meeting stricter ozone standards within the same timeframe as the previous standard. For example, Los Angeles would need to comply with the revised National Ambient Air Quality Standards (NAAQS) under Subpart 1 by the same year that marks the deadline for Subpart 2's one-hour ozone standard. The interpretation of Subpart 2 is inconsistent with its intended structure and purpose, rendering the EPA's implementation policy unlawful, though the Court of Appeals' reasoning was not entirely upheld. The EPA is tasked with developing a reasonable interpretation of the nonattainment implementation provisions for the revised ozone NAAQS following the remand.

Key rulings include: 
1) The EPA cannot factor in implementation costs when setting primary and secondary NAAQS under the Clean Air Act (CAA) § 109(b).
2) § 109(b)(1) does not grant the EPA legislative powers contrary to Article I, Section 1 of the Constitution.
3) The Court of Appeals has jurisdiction over the EPA's interpretation of Part D of Title I of the CAA concerning revised ozone NAAQS.
4) The EPA's interpretation of Part D is deemed unreasonable.

The Court of Appeals' judgment is partially affirmed and partially reversed, with cases remanded for further proceedings. Additionally, the notes clarify that the sections of the CAA referenced do not allow for the consideration of costs in the standard-setting process, and that while the Scientific Review Committee's findings are relevant, cost data does not bear significance in this context. The EPA is also prohibited from considering implementation costs when establishing secondary NAAQS, which must be set to protect public welfare from known or anticipated adverse effects of air pollutants.

Respondents' claims regarding the EPA's alleged secret cost considerations for attainment are deemed irrelevant to the interpretive analysis. If proven, such claims could justify vacating the National Ambient Air Quality Standards (NAAQS) due to the Administrator's failure to comply with legal requirements, as established in precedent cases like Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc. and Atlantic Mut. Ins. Co. v. Commissioner. However, this would not warrant the Court altering existing law.

Table I outlines the primary standard classifications, design values, and respective attainment dates based on the date of November 15, 1990. Classifications range from Marginal (0.121 to 0.138 ppm, 3 years for attainment) to Extreme (0.280 ppm and above, 20 years for attainment).

Justice Thomas expresses agreement with the majority’s view on the intelligible principle guiding agency directives but raises concerns about potential constitutional issues with Section 109, noting a lack of focus on the Constitution's text by the parties involved. He questions whether the intelligible principle doctrine adequately addresses the separation of powers and indicates a willingness to reconsider this doctrine in future cases.

Justice Stevens, concurring with Justice Souter, supports the Court's conclusion that Section 109(b)(1) appropriately delegates authority to the EPA Administrator to establish NAAQS and agrees with the Court's reasoning regarding the alleged unconstitutional delegation of legislative power.

The excerpt argues for the characterization of the power delegated to the EPA as "legislative power," asserting that such delegation is constitutional when limited by the terms of the authorizing statute. It critiques the Court's position, suggesting that acknowledging agency rulemaking as legislative is both accurate and consistent with constitutional text. The argument emphasizes that legislative power should be defined by the nature of the power exercised rather than the identity of the delegate, citing examples where agencies create rules that bind the public. It references the constitutional framework, noting that Articles I and II do not prohibit Congress from delegating legislative authority. The author contends that an executive agency's rulemaking, when based on a valid delegation, can be deemed legislative as long as there is a clear guiding principle. The author aligns with the Court's opinion in most respects but concludes that the delegation of legislative power to the EPA under section 109 is constitutional.

The excerpt highlights the necessity for Congress to delegate power to effectively govern in a complex society, emphasizing that the nondelegation principle does not restrict only Congress from establishing rules with prospective effect. Historically, the Supreme Court has rarely enforced its prohibition on congressional delegation of legislative power. Justice Breyer concurs with parts of the Court's opinion, specifically noting that the Clean Air Act does not allow the Environmental Protection Agency (EPA) to consider economic costs when setting national air quality standards under § 109(b)(1). He argues for a broad interpretation of regulatory statutes to allow for rational regulation, but acknowledges that in this instance, legislative history and the statute's structure indicate Congress intended to withhold from the EPA the authority to factor in economic costs. The legislative history reveals that the Act was designed to be "technology forcing," prioritizing public health over economic feasibility or technological limitations. The Senate's discussions clarified that health concerns should take precedence over technical feasibility in establishing air quality standards, underscoring the intent that existing sources of pollution must comply with these standards or be shut down.

The Court's review of the legislative history indicates that the 1970 amendments to the Clean Air Act were intentionally designed to compel regulated sources to create pollution control technologies, even if they initially seemed economically or technologically unfeasible. These amendments were viewed as a necessary and robust response to a significant environmental issue. Subsequent legislation, including the 1977 and 1990 amendments, reaffirmed and intensified these "technology-forcing" goals, emphasizing the establishment of ambient air quality standards that prioritize public health over economic considerations.

The history suggests that Congress did not intend irrationality in its goals, as demonstrated by the successful development of catalytic converter technology, which addressed concerns regarding the high costs of emission reductions. While the technology-forcing objective complicates the assessment of implementation costs—since they involve uncertain future technologies—it does not entirely disregard cost and feasibility. Regulatory bodies are permitted to consider economic factors in their implementation plans, allowing states to choose control methods that account for costs and enabling industries facing challenges to seek exemptions. The EPA can also factor in costs when establishing deadlines for compliance with air quality standards.

The document outlines the regulatory framework for establishing and extending deadlines for achieving ambient air quality standards, particularly concerning ozone nonattainment areas. It specifies that the initial period for compliance should not exceed 10 years from the designation as nonattainment, with the possibility for the Administrator to grant up to two one-year extensions. It emphasizes that while the standards aim to protect public health, the EPA is not mandated to eliminate all health risks at any economic cost, allowing for flexibility to avoid overly stringent standards that could jeopardize industry. The term "requisite to protect the public health" is clarified as not implying a risk-free environment; rather, it acknowledges an acceptable level of risk based on contextual factors. The Administrator is empowered to consider comparative health risks when setting standards, ensuring that proposed regulations do not inadvertently cause greater harm than they prevent. Ultimately, the judgment of the Administrator is central to determining what constitutes adequate protection of public health under the statute.

The Administrator is granted substantial discretionary authority under the statute to establish standards related to pollutants. This authority includes evaluating the severity of health effects, the number of affected individuals, the distribution of these effects, and uncertainties in estimates. The Administrator may also consider comparative health consequences and contextual factors when assessing acceptable health risks. This level of discretion is deemed adequate to alleviate concerns from industry stakeholders, as the EPA can choose not to regulate risks it deems trivial, thus preventing unnecessary deindustrialization. The argument is made that a regulatory standard should not demand a return to preindustrial living conditions, which were not healthful. The conclusion reached emphasizes that Section 109 does not permit the EPA to incorporate the economic costs of compliance into the national ambient air quality standards.
