Natural Resources Defense Council v. Environmental Protection Agency
Natural Resources Defense Council v. Environmental Protection Agency
Opinion of the Court
Opinion for the Court filed PER CURIAM.
Opinion concurring in part and dissenting in part filed by Circuit Judge ROGERS.
In 1997, the EPA revised the National Ambient Air Quality Standard (NAAQS) for ozone from a 1-hour standard to an 8-hour standard. These consolidated petitions for review challenge aspects of the Final Rule To Implement the 8-Hour Ozone National Ambient Air Quality Standard — Phase 2, 70 Fed.Reg. 71,612 (2005) (Phase 2 Rule), and Phase 2 of the Final Rule To Implement the 8-Hour Ozone National Ambient Air Quality Standard — Notice of Reconsideration, 72 Fed.Reg. 31,727 (2007) (Reconsideration Notice). We hold the Phase 2 Rule is inconsistent with the Clean Air Act (CAA or Act) in allowing participation in a regional cap-and-trade program to satisfy an area-specific statutory mandate. We further hold the EPA arbitrarily eliminated one safeguard and violated the anti-backsliding provision of the Act insofar as it eliminated another from its regulations governing review of new sources of pollution. We therefore grant the petitions with respect to those aspects of the Phase 2 Rule. In view of our decision in North Carolina v. EPA, 531 F.3d 896 (2008), in which we granted a petition for review of the Clean Air Interstate Rule (CAIR), we defer consideration of the Phase 2 Rule and Reconsideration Notice insofar as they relate to the CAIR program. We deny the petitions in all other respects.
I. Background
The Act requires the EPA to designate areas as attainment, nonattainment, or un~ classifiable for each NAAQS. CAA § 107(d)(1)(B), 42 U.S.C. § 7407(d)(1)(B). States have primary responsibility for implementing those standards, and must submit a state implementation plan (SIP) that specifies how the state will achieve and maintain compliance with the NAAQS. Id. § 7407(a). Part D of the Act provides the SIP for a nonattainment area must include certain control measures. Id. § 7501 et seq. Subpart 1 applies to all nonattainment areas, id. §§ 7501-7509a, whereas Subpart 2 specifies additional requirements for ozone nonattainment areas, id. § § 7511-7511 f. Section 181 of the Act classifies ozone nonattainment areas from “marginal” to “extreme” based upon the degree to which the ozone level in the area exceeds the NAAQS. Id. § 7511. An area that exceeds the NAAQS by a greater margin is given more time to meet the standard but is subjected to progressively more stringent emissions controls for ozone precursors, namely, volatile organic compounds (VOCs) and oxides of nitrogen (NOx). See CAA § 182, 42 U.S.C. § 7511a.
In 1997, the EPA determined the NAAQS for ozone, expressed as the amount of ozone in the ambient air averaged over one hour, was inadequate to protect public health. The EPA therefore promulgated a new NAAQS of .08 ppm of ozone averaged over eight hours. Under the 8-hour standard, some ozone nonattainment areas are subject only to the more flexible requirements of Subpart 1, while areas with higher levels of ozone are subject to the additional requirements of Subpart 2. See S. Coast Air Quality Mgmt.
The EPA implemented the 8-hour NAAQS in two phases; the Phase 2 Rule and Reconsideration Notice here under review implement the requirements of Sub-part 1 and Subpart 2 for areas not attaining the 8-hour NAAQS. The consolidated petitions challenge those rules as follows. The Natural Resources Defense Council, the States of New Jersey, Connecticut, and New York, and the National Petrochemical and Refiners Association challenge provisions implementing the statutory requirement that each nonattainment area provide for such emissions reductions as may be obtained by the adoption of reasonably available control technology (RACT). The NRDC and New Jersey challenge provisions governing review of new sources of pollution. The NRDC also challenges two provisions implementing the statutory requirements that a SIP for a nonattainment area provide for specific percentage reductions in emissions and for contingency measures. Finally, the Chamber of Greater Baton Rouge and affiliated petitioners
We review the EPA’s interpretation of the Act pursuant to 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): We ask first whether the Congress has “directly spoken to the precise question at issue.” Id. at 842, 104 S.Ct. 2778. If so, then we must “give effect to the unambiguously expressed intent of Congress.” Id. at 843, 104 S.Ct. 2778. If, however, the “statute is silent or ambiguous with respect to the specific issue,” then we defer to the EPA’s interpretation as long as it is “based on a permissible construction of the statute.” Id. The Act requires us to review the Phase 2 Rule deferentially to determine only whether it is “arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law.” CAA § 307(d)(9)(A), 42 U.S.C. § 7607(d)(9)(A); see Bluewater Network v. EPA, 372 F.3d 404, 410 (D.C.Cir. 2004) (“We give particular deference to the EPA when it acts under unwieldy and science-driven statutory schemes like the Clean Air Act”) (internal quotation marks omitted).
II. Reasonably Available Control Technology
Section 172(c)(1) of the Act requires that the SIPs for nonattainment areas “provide for the implementation of all reasonably available control measures as expeditiously as practicable (including such reductions in emissions from existing sources in the area as may be obtained through the adoption, at a minimum, of reasonably available control technology).” 42 U.S.C. § 7502(c)(1) (emphasis added). Ozone nonattainment areas that are subject to Subpart 2 of Part D are subject to more specific reasonably available control technology requirements. E.g., id. § 7511a(b)(2)(C); id. § 7511a(f). Petitioners challenge three aspects of the implementation of the RACT requirement in the Phase 2 Rule. First, the NRDC challenges the rule providing that RACT is satisfied for Subpart 1 areas by SIPs “demonstrating that the area has adopted all control measures necessary to demonstrate attainment as expeditiously as possible,” Phase 2 Rule, 70 Fed.Reg. at 71,701 (codified at 40 C.F.R. § 51.912(c)(1)). Second, the State of New Jersey challenges the EPA’s decision to allow states to meet the RACT
A. RACT in Subpart 1 Nonattainment Areas
The NRDC challenges the Phase 2 Rule’s treatment of the “reasonably available control technology” requirement of CAA § 172(e)(1), 42 U.S.C. § 7502(c)(1). Under the Phase 2 Rule, nonattainment areas governed by Subpart 1 that request an attainment deadline within five years of their designation “shall meet the RACT requirement by submitting an attainment demonstration SIP demonstrating that the area has adopted all control measures necessary to demonstrate attainment as expeditiously as practicable.” Phase 2 Rule, 70 Fed.Reg. at 71,701/3 (codified at 40 C.F.R. § 51.912(c)(1)). The NRDC contends that this provision is an unlawful waiver of the RACT requirement of § 172(c)(1) because, under the Phase 2 Rule, a state need not require RACT at all in such areas. It views the statutory phrase “at a minimum” as imposing an unambiguous requirement for all nonattainment areas. The NRDC thus contends the Phase 2 Rule violates the plain text of § 172(c)(1) by doing away with this requirement in some nonattainment areas. However, we conclude that the term “reasonably available control technology” is ambiguous in context and that the EPA’s interpretation is reasonable.
The court has previously concluded that the term “reasonably available” in the analogous phrase “reasonably available control measure” (RACM) in § 172(c)(1) is ambiguous and “clearly bespeaks [the Congress’s] intention that the EPA exercise discretion in determining which control measures must be implemented....” Sierra Club v. EPA 294 F.3d 155, 162-63 (D.C.Cir. 2002). The court explained that the statute did not specify which control measures would be deemed “reasonably available” and did not “compel[ ] a state to consider whether any measure is ‘reasonably available’ without regard to whether it would expedite attainment in the relevant area.” Id. at 162. Thus, the EPA had discretion to conclude that a measure was not “reasonably available” if it would not expedite attainment. Id. Because the same is true of the phrase “reasonably available control technology,” the term “reasonably available” within RACT is also ambiguous. Moreover, even if the phrase “at a minimum” requires that at least RACT-level reductions be achieved in all nonattainment areas, the phrase does not specify the content of the RACT requirement. Given this ambiguity, the EPA has discretion reasonably to define the controls that will demonstrate compliance.
Contrary to the NRDC’s arguments, the RACT requirement does not lose all meaning under the EPA’s definition. When control technology is necessary to advance attainment, it is “reasonably available” under the definition and would be required under the rule. The fact that the RACT requirement was previously located in a separate section and not in a parenthetical modifying the RACM requirement does not support the NRDC’s position. Compare CAA § 172(b)(2), 42 U.S.C. § 7502(b)(2), (3) (1977), with CAA § 172(c)(1), 42 U.S.C. § 7502(c)(1) (1990). Rather, the fact that the Congress moved the requirement to a parenthetical modifying the RACM requirement supports the EPA’s conclusion that the RACT requirement could be interpreted in the same manner as the RACM requirement. Although both the NRDC and the EPA point to legislative history purportedly supporting their positions, neither points to legislative history bearing on the meaning of “reasonably available.” See H.R. Rep. No. 101-490, reprinted in 2 Legislative History of the Clean Air Act Amendments of 1990, at 223. The term “reasonably available” is ambiguous, and the EPA’s interpretation is a permissible construction of the statute.
B. Certifying 8-Hour RACT Based Upon 1-Hour RACT
The Phase 2 Rule provides that a control measure approved as RACT under the 1-hour standard will be approved as RACT under the 8-hour standard absent information indicating it should not be approved. Phase 2 Rule, 70 Fed.Reg. at
The EPA promulgates two types of guidance that assist states in determining what control techniques meet the RACT requirement, control techniques guidelines (CTGs) and alternative control techniques (ACTs). Section 183 of the Act requires the EPA to issue CTGs for certain categories of sources that emit VOCs. See 42 U.S.C. § 7511b. Where CTGs exist, they establish the presumptive level of control meeting RACT. Phase 2 Rule, 70 Fed.Reg. at 71,654/3. Still, states can opt to require alternative controls rather than following the guidance in the CTGs. Notice of Final Determination and Availability of Final Control Techniques Guidelines, 71 Fed. Reg. 58,745, 58,747 (Oct. 5, 2006). Section 183(c) of the Act requires the EPA to issue ACTs for major sources of VOCs and NOx. 42 U.S.C. § 7511b(e). The ACTs “describe available control techniques and their cost effectiveness” but do not establish presumptive RACT. Phase 2 Rule, 70 Fed.Reg. at 71,654/3. Thus, neither the CTGs nor ACTs set firm RACT requirements.
Despite New Jersey’s concerns, the EPA’s certification provision does not conflict with the Act and is not arbitrary and capricious. Although the EPA did not revise the guidance documents, the EPA’s case-by-case approach adequately ensures that RACT determinations will take into account advances in technology. First, the EPA has directed states to consider available information in addition to the CTG and ACT documents when making RACT determinations. Id. at 71,655/1. If a state is presented with information indicating that a previous RACT determination is inappropriate, the state must consider that information and modify its RACT determinations accordingly. Id. Second, when submitting RACT certifications to the EPA as part of their RACT SIP submissions, states must provide supporting .information. Id. at 71,655/2. Third, if additional information is presented during notice-and-comment rulemaking, both the state and the EPA are required to consider that information as part of the rulemaking; this includes information presented during notice-and-comment rule-making for RACT SIP submissions for previously controlled sources. Id. Because the EPA could reasonably conclude that these mechanisms will ensure the case-by-case determinations will take into account advances in technology, the EPA could also reasonably conclude “that the best way to address the possibility that CTGs or ACTs might not reflect all currently available technologies was by requiring each State to consider any new available information in making its certification, which will then be reviewed by the EPA as part of the SIP submission process,” EPA Br. at 67; see also Phase 2 Rule, 70 Fed.Reg. at 71,655/1. See Nat’l Wildlife Fed’n v. EPA 286 F.3d 554, 566-67 (D.C.Cir. 2002). Likewise, given the as
Additionally, even if the EPA had revised the national guidelines and provided uniform criteria as New Jersey preferred, such actions would not have eliminated case-by-case inquiries by the states and the EPA. Both the CTGs and ACTs are guidance documents, see Conn. Fund for the Env’t v. EPA, 672 F.2d 998, 1003 (2d Cir. 1982); United States v. Ford Motor Co., 736 F.Supp. 1539, 1543 (W.D.Mo. 1990), and neither sets firm RACT requirements. Thus, despite the existence of the CTGs, the EPA makes case-specific determinations as part of its SIP approval process. Notice of Final Determination and Availability of Final Control Techniques Guidelines, 71 Fed.Reg. at 58,747. ACTs are also merely guidelines and do not create presumptive RACT levels. Phase 2 Rule, 70 Fed.Reg. at 71,654/3. As case-by-case determinations would be necessary even if the EPA had revised the guidance documents, the EPA could reasonably determine that the costs entailed in revising the guidance documents outweighed the benefits. The EPA has discretion to consider the costs of regulation unless the relevant statute precludes such a consideration. See, e.g., Sierra Club, 294 F.3d at 162-63.
The EPA’s approach also addresses New Jersey’s concern that allowing states to make RACT determinations by relying on 15-year-old CTGs plus new information, if any, provided by the public in comments is “an inadequate substitute” for requiring each state to undertake a new RACT determination for each source category. As noted, the EPA has directed states to submit supporting documentation along with RACT certifications. Phase 2 Rule, 70 Fed.Reg. at 71,655/2. Thus, the EPA will have available the information needed to verify states’ determinations that the previous controls are still appropriate under the 8-hour standard. Additionally, persons disagreeing with a particular RACT certification can seek judicial review of a particular SIP approval. A state may also complete an entirely new RACT analysis if it so chooses. Id. at 71,652/3.
In sum, we hold that the EPA’s decision to forego a revision of the nationwide guidelines in favor of case-by-case RACT certifications was reasonable and not inconsistent with the statutory goal of expeditious attainment. Because the Phase 2 Rule requires each state to verify that previously-required RACT controls still satisfy the RACT requirement, we need not address the EPA’s assertion that a new RACT determination will likely “result in the same or similar control technology as the initial RACT determination under the 1-hour standard because the fundamental control techniques ... are still applicable.” Id. at 71,654/1. The EPA did not rest the rule upon this ground; each state must “consider new information” — information that may prove the EPA wrong — when the state determines whether previously-required controls “still represent! ] an appropriate RACT level of control.” Id. at 71,655/1.
C. Meeting RACT via NOx SIP Call
The NOx SIP Call is a cap-and-trade program that regulates NOx emissions. The program covers 22 states in the Northeast and the District of Columbia, and was intended to address the interstate transport of ozone. See generally Final Rule, Finding of Significant Contribution and Rulemaking for Certain States in the Ozone Transport Assessment Group Region for Purposes of Reducing Regional
The Phase 2 Rule provides that to meet the NOx RACT requirement, “the State need not perform (or submit) a NOx RACT analysis for sources subject to the state’s emission cap-and-trade program” where that program meets the NOx SIP Call requirements or, in states achieving CAIR reductions solely from Electricity Generating Units, CAIR requirements. Id. at 71,652/3. Petitioners and intervenors persuasively challenge this provision as being contrary to the express terms of the statute.
Section 172(c)(1) of the Act requires that nonattainment areas achieve “such reductions in emissions from existing sources in the area” as can be achieved by the adoption of RACT. 42 U.S.C. § 7502(c)(1). Thus, the RACT requirement calls for reductions in emissions from sources in the area; reductions from sources outside the nonattainment area do not satisfy the requirement. See id.; see also CAA § 182(b)(2), 42 U.S.C. § 7511a(b)(2) (requiring implementation of RACT with respect to certain VOC sources “in the area” for moderate and above nonattainment areas). Accordingly, participation in the NOx SIP Call could constitute RACT only if participation entailed at least RACTlevel reductions in emissions from sources within the nonattainment area. In the preamble to the proposed rule the EPA stated that “the overall emission reductions from sources in the NOx SIP Call cap-and-trade program will achieve more emissions reductions in the nonattainment area than would application of RACT to each of those units,” Proposed Rule to Implement the 8-Hour Ozone National Ambient Air Quality Standard, 68 Fed. Reg. 32,802, 32,839 (June 2, 2003) (Proposed Rule). The preamble to the final rule does not go as far. Rather, the final preamble states only that the “NOx SIP Call is estimated to achieve a beyondRACT degree of control regionally,” Phase 2 Rule, 70 Fed.Reg. at 71,657. Such regionwide RACT-level reductions in emissions do not meet the statutory requirement that the reductions be from sources in the nonattainment area. Because the EPA has not shown that NOx SIP Call compliance will result in at least RACTlevel reductions in emissions from sources within each nonattainment area, the EPA’s determination that compliance with the NOx SIP Call satisfies the RACT requirement is inconsistent with the “in the area” requirement and thus violates the plain text of § 172(c)(1).
In an analogous situation, the court invalidated the CAIR trading program because the EPA’s regionwide approach made it impossible to tell whether the rule achieved a specific statutory objective. See North Carolina v. EPA 531 F.3d 896, 906-08 (D.C.Cir. 2008). In developing CAIR, the court explained, the EPA “did not purport to measure each state’s significant contribution to specific downwind nonattainment areas and eliminate them in an isolated state-by-state manner.” Id. at 907. Despite a statutory provision prohibiting sources “within the State” from contributing significantly to nonattainment in “any other State,” CAA § 1 10(a)(2)(D), 42 U.S.C. § 7410(a)(2)(D), the EPA adopted a
The EPA responds that its approach “gives meaning to the statute’s ‘in the area’ language” because its technical analysis shows that the cap-and-trade programs achieve greater reductions than would the application of RACT-level controls at each source. EPA Br. at 73. However, the EPA’s cited support for this proposition is the statement from the preamble to the proposed rule stating the EPA “believes” participation would “achieve more emissions reductions in the nonattainment area than would application of RACT” to all sources in the area. Proposed Rule, 68 Fed.Reg. at 32,839/2. That statement is unsupported by any record evidence and it does not appear in the preamble to the final rule. The EPA’s further response that its technical analysis supports the conclusion that NOx SIP Call participation meets the RACT requirement is no more persuasive. The EPA explains that its analysis showed that sources subject to the NOx SIP Call “collectively” would achieve beyond-RACT reductions in emissions. EPA Br. at 83. But region-wide reductions do not satisfy the “in the area” requirement. The EPA explains further that it found that purchasing allowances was more costly than installing RACT-level control technology and thus “most” sources meeting the NOx SIP call, “assuming rational economic behavior,” id., would opt to install controls rather than purchase allowances. This bare assertion is insufficient to demonstrate that NOx SIP Call compliance would lead to RACTlevel reductions from sources in the area. Even if most sources in a nonattainment area installed controls rather than purchasing allowances, a small number of sources purchasing allowances and increasing emissions could mean that overall emissions from sources in the area remained unchanged or even increased.
The EPA’s attempt to show ambiguity in the Act is likewise unavailing. The EPA maintains the statute is ambiguous as to whether RACT must be installed at each source in an area, noting that it has previously approved the concept of averaging emissions within a nonattainment area. The EPA reads the statutory phrase “as may be obtained” to indicate that the RACT requirement does not necessarily call for implementation of controls at each and every source, but rather requires an area to achieve at least RACT-level reductions in emissions. Even if the RACT requirement could be met through an emissions-averaging approach within a nonattainment area, averaging emissions across a region does not ensure that any reductions in emissions derive from reductions at sources within a particular area. Even if the EPA were correct that “nothing in the statute precludes consideration of the air quality impact that controls under a region-wide cap-and-trade program may have on NOx within the nonattainment area,” EPA Br. at 72, the EPA has not considered the impact of the NOx SIP Call on the air quality within specific non-attainment areas. Therefore the EPA has failed to demonstrate that NOx SIP Call compliance can be equated to RACT compliance.
The EPA’s reliance on § 172(c)(6) is misplaced. That section provides that
The EPA also offers that to the extent individual sources emitting high levels of NOx are in compliance with the NOx SIP Call through the purchase of allowances, the states can define RACT to require greater reductions than are required by the EPA, and they must require beyondRACT reductions as necessary to achieve timely attainment. The EPA’s determination that NOx SIP Call compliance satisfies the RACT requirement is not based on a state choosing to so exercise its discretion. A state’s decision to require stricter controls cannot eliminate the defect in the EPA’s approach — failing to implement the requirement of at least RACT-level reductions in emissions from sources in the non-attainment area. This part of the Phase 2 Rule must therefore be remanded without vacatur because the EPA may be able to reinstate the provision for most nonattainment areas if, upon conducting a technical analysis, it finds the NOx SIP Call results in greater emissions reductions in a nonattainment area than would be achieved if RACT-level controls were installed in that area.
III. Clean Data Policy
Under the Act, each nonattainment area must attain the NAAQS by a deadline, known as the “attainment date,” which is established by the statute itself for areas subject to Subparts 1 and 2, see CAA § 181, 42 U.S.C. § 7511, and by the EPA for areas subject only to Subpart 1, see CAA § 172, 42 U.S.C. § 7502(a)(2). The Act also provides that the SIP for a nonattainment area subject only to Subpart 1 must “require reasonable further progress” (RFP), id. § 7502(c)(2); the SIP for an area in moderate or a greater degree of nonattainment must provide for fixed percentage reductions of VOCs on a specified schedule. CAA §§ 182(b)(1)(A), (c)(2)(B), 42 U.S.C. §§ 7511a(b)(l)(A), (c)(2)(B).
In order to ensure these requirements are met, the SIP for any nonattainment area must include “contingency measures” to be implemented “if the area fails to make reasonable further progress, or to attain the [NAAQS] by the attainment date,” CAA § 172(c)(9), 42 U.S.C. § 7502(c)(9), and the SIP for a serious, severe, or extreme nonattainment area must also include “contingency measures” that will take effect automatically “if the area fails to meet any applicable milestone,” CAA § 182(c)(9), 42 U.S.C. § 7511a(c)(9).
In the Phase 2 Rule, the EPA suspended the planning requirements for specified percentage reductions and contingency
The NRDC contends the Clean Data Policy conflicts with both the letter and the purpose of the Act. More specifically, the NRDC argues the statutory provisions requiring a SIP to include contingency measures and percentage reductions allow no waivers for an area that has achieved the NAAQS; the only way for an area to be absolved of those requirements is to be redesignated an attainment area. See CAA § 175A(c), 42 U.S.C. § 7505a(c) (“Until [a maintenance] plan revision is approved and an area is redesignated as attainment ... the requirements of [Part D] shall continue in force and effect”). Further, the NRDC argues only its reading of the text is consistent with the intent of the Congress that, in order to ensure the air stays clean, no mandatory control requirement be lifted until a maintenance plan is in place.
The EPA responds first that the NRDC did not raise before the agency and therefore forfeited its objection to the suspension of the planning requirement for contingency measures. See CAA § 307(d)(7)(B), 42 U.S.C. § 7607(d)(7)(B) (“Only an objection to a rule or procedure which was raised with reasonable specificity during the period for public comment ... may be raised during judicial review”)We agree. We “enforce[] this provision strictly,” Motor & Equip. Mfrs. Ass’n v. Nichols, 142 F.3d 449, 462 (D.C.Cir. 1998) (internal quotation marks omitted), and although we allow commenters “some leeway in developing their argument before this court,” the comment must have provided “adequate notification of the general substance of the complaint,” S. Coast Air Quality Mgmt. Dist. v. EPA, 472 F.3d 882, 891 (D.C.Cir. 2006).
The NRDC’s comments did not provide the EPA adequate notice that it objected to the suspension of the contingency measures. The NRDC did object to the Clean Data Policy, but only to the suspension of the requirements for an attainment demonstration and percentage reductions. The NRDC now contends it objected to the suspension of all Subpart 2 requirements, pointing to its comment that the “EPA cannot authorize states to simply drop subpart 2 measures when the area is meeting either standard. The Act allows states to move mandated controls to a maintenance contingency plan, but only after the area has been redesignated to attainment.” Comments of Clean Air Task Force et al., at 48 (Aug. 1, 2003). That comment, however, was made in the context of an objection to a different provision of the proposed rule, namely the EPA’s determination that an area not attaining the 1-hour standard but meeting the 8-
On the merits, the EPA maintains the Clean Data Policy does not waive the planning requirements for percentage reductions; instead, it contends, those requirements are by their terms inapplicable when an area meets the applicable NAAQS. See Phase 2 Rule, 70 Fed.Reg. at 71,645/1-2, 71,646/1-2.
The two planning requirements for percentage reductions are CAA § 182(b)(1), which requires an initial reduction of 15% of VOC emissions in the first six years for an area in moderate or greater nonattainment, and § 182(c)(2)(B), which requires subsequent reductions in VOC emissions averaging 3% per year for an area in serious or greater nonattainment unless an exception applies. See 42 U.S.C. § 7511a(b)(l), (c)(2)(B). As the EPA interprets these provisions, specific percentage reductions are required only as necessary to achieve attainment.
We think the statute unclear as to whether those sections apply to an area that is already attaining the NAAQS. For the reasons below, we join the Tenth Circuit in holding the EPA’s interpretation is reasonable. See Sierra Club v. EPA, 99 F.3d 1551 (10th Cir. 1996).
Section 182(b)(1)(A)® initially requires the SIP for an area in moderate or greater nonattainment to plan a total reduction in VOC emissions of 15% over six years. 42 U.S.C. § 7511a(b)(l)(A)(i). In the very next sentence, however, it elaborates that a plan should mandate “such specific annual reductions ... as necessary to attain the [NAAQS] for ozone by the attainment date.” Id. Moreover, each percentage reduction is linked to the requirement that an area make “reasonable further progress” toward attainment. See id. § 7511a(b)(l) (entitled “Plan provisions for reasonable further progress”); id. § 7511a(c)(2)(B) (entitled “Reasonable further progress demonstration”). “Reasonable further progress,” in turn, means “such annual incremental reductions in emissions ... as are required ... for the purpose of ensuring attainment.” CAA § 171(1), 42 U.S.C. § 7501(1). The Act is therefore ambiguous as to what reductions are required when no further progress toward attainment is necessary — or, for that matter, possible. The EPA reasonably resolved this ambiguity by concluding the specific percentage reductions are simply inapplicable in that circumstance. As the Tenth Circuit put the matter, “If a moderate ozone nonattainment area has in fact already attained the ozone standard, it would make little sense to require a state to demonstrate the area will make reasonable progress toward attainment.” Sierra Club, 99 F.3d at 1557.
The EPA’s reasoning disposes as well of the NRDC’s contentions that the Clean Data Policy unlawfully circumvents the re-designation requirements, CAA § 107(d)(3)(E), 42 U.S.C. § 7407(d)(3)(E), violates the mandate that all Part D requirements remain in force until an area has an approved maintenance plan in place, CAA § 175A(c), 42 U.S.C. § 7505a(c), and disregards the Supreme Court’s admonition that the EPA cannot “render Subpart 2’s carefully designed restrictions on EPA discretion utterly nugatory,” Whitman v. Am. Trucking Ass’ns, 531 U.S. 457, 484, 121 S.Ct. 903, 149 L.Ed.2d 1 (2001). The Clean Data Policy does not effect a redesignation; an area must still comply with the statutory requirements before it can be redesignated to attainment. Furthermore, Part D — in-
IV. 15% VOC Reduction
CAA section 182(b)(1) requires that, for a moderate nonattainment area, “no later than 3 years after November 15, 1990, the State shall submit a revision to the applicable implementation plan to provide for volatile organic compound emission reductions, within 6 years after November 15, 1990, of at least 15 percent from baseline emissions, accounting for any growth in emissions after 1990.” 42 U.S.C. § 7511 a(b)(l)(A)(i). CAA section 182(c), (d) and (e) incorporate the 15% VOC reduction requirement for, respectively, “serious,” “severe” and “extreme” nonattainment areas. Id. § 7511 a(c)-(e). After the initial six-year period, CAA section 182(c), (d) and (e) impose on the same areas an additional RFP requirement that the SIP be revised so that it “will result in VOC emissions reductions from the baseline emissions ... [of] at least 3 percent of baseline emissions each year,” “averaged over each consecutive 3-year period beginning 6 years after November 15, 1990, until the attainment date.” Id. § 7511 a(c)(2)(B)(i) (imposing requirement on “serious” areas); see id. § 7511a(d), (e) (incorporating 3% reduction requirement for “severe” and “extreme” areas).
In the Phase 2 Rule, the EPA determined that for all moderate and above areas “that had not met the 15 percent VOC emission reduction requirement for the 1-hour standard,” the RFP 15% reduction requirement “would apply” under the 8-hour standard. 70 Fed.Reg. at 71,632-33. Conversely, the EPA determined, 8-hour moderate and above areas that had already satisfied the 15% VOC emission reduction for the 1-hour standard will not be subjected a second time to the 15% requirement under the 8-hour standard. Id. at 71,633. Thus, “[a]reas classified under subpart 2 as moderate that had met the 15 percent VOC emission reduction requirement for the 1-hour standard are treated in the final rule like areas covered under subpart 1,” while “[a]reas classified under subpart 2 as serious and above that had met the 15 percent VOC emission reduction requirement for the 1-hour standard would be subject to the RFP requirement in section 172(e) [sic
First, the NRDC argues that the EPA “illegally waived” Subpart 2’s RFP requirement that each SIP be revised three years after the statute’s effective date to provide for a 15% VOC reduction within 6 years after enactment for all areas classified as “moderate” and above for ozone.
As an initial matter, the EPA did not “waive” the 15% requirement but simply determined that, if a State had made the required revision for an area classified as moderate or greater when the one-hour NAAQS took effect, the State did not have to do so a second time after the 8-hour standard took effect. In so doing, the EPA reasonably resolved a statutory ambiguity under step 2 of the framework set out in Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc., 467 U.S. 837, 843, 104 S.Ct. 2778, 81 L.Ed.2d 694 (1984). See Natural Res. Def. Council v. EPA 489 F.3d 1250, 1257 (D.C.Cir. 2007) (“Under Chevron: We first ask ‘whether Congress has directly spoken to the precise question at issue,’ in which case we ‘must give effect to the unambiguously expressed intent of Congress.’ If the ‘statute is silent or ambiguous with respect to the specific issue,’ however, we move to the second step and defer to the agency’s interpretation as long as it is ‘based on a permissible construction of the statute.’” (quoting Chevron, 467 U.S. at 842-43, 104 S.Ct. 2778) (internal quotation marks omitted)). Accordingly, we reject the NRDC’s challenge to the VOC reduction provision.
The NRDC contends that the EPA’s reading of the statute is “untenable” because the statute requires that the SIP provide for a 15% reduction from “baseline emissions ” — which the “EPA itself defines ... for purposes of the 8-hour ozone standard as emissions in 2002, not 1990” — and that the reduction be effected “ ‘within 6 years after’ the baseline year— that is, between 2002 and 2008 for the 8-hour standard.” NRDC Br. at 29. This argument, however, sidesteps the EPA’s rationale for its interpretation. The EPA identified a “gap in the statutory scheme” because “[t]he CAA is silent regarding whether a nonattainment area that implements the 15-percent VOC emission reduction of 42 U.S.C. § 7511a(b)(l)(A) must implement that provision a second time if the NAAQS is revised, or instead must implement other RFP provisions that expressly would have applied had there been no revision of the NAAQS.” EPA Br. at 29. The EPA filled this gap by selecting the latter resolution. As the EPA explained in the Phase 2 Rule, while it “believes that the CAA is quite clear that the SIP must provide for a 15 percent reduction in baseline VOC emissions for some period after 1990 in an area subject to section 182(b)(1)(A),” it “disagrees that the CAA plainly requires that the SIP for an area must require a second 15 percent reduction in VOC baseline emissions under a revised ozone standard.” 70 Fed. Reg. at 71,635-36 (first emphasis added); see also id. at 71,634 (“For those areas that have an approved 15 percent plan for their 1-hour ozone SIPs, an additional 15 percent VOC reduction is not necessary.”).
The NRDC also argues that the EPA’s 15% approach is inconsistent with its treatment of section 182(c)(2)(B)(i)’s 3% reduction requirement for serious and above areas in that the “EPA does not read the Act as excusing such 3% continuing emission cuts for serious and above 8-hour nonattainment areas merely because they may have had plans under the 1-hour standard to achieve continuing (i.e. post-1996) cuts of 3%/yr from a 1990 baseline.” NRDC Br. at 30 n. 8. The 3% provision, however, is fundamentally different from the 15% provision in that the former does not (as does the latter) establish a onetime reduction requirement but instead imposes a continuing obligation that applies to “each consecutive 3-year period beginning 6 years after November 15, 1990, until the attainment date.” CAA § 182(c)(2)(B), 42 U.S.C. § 7511a(c)(2)(B).
Finally, the NRDC asserts that the “EPA cannot override an express statutory command ‘simply by asserting that its preferred approach would be better policy,’ ” NRDC Br. at 30 (quoting Engine Mfrs. Ass’n v. EPA, 88 F.3d 1075, 1089 (D.C.Cir. 1996)), referring to the EPA’s observation that its approach “provides flexibility to States to use a mix of NOx and VOC reductions” under CAA section 172, 42 U.S.C. § 7502, rather than the required VOC-only reductions mandated by CAA section 182(b)(l)(A)(l), 42 U.S.C. § 7511a(b)(l)(A)(l). 70 Fed.Reg. at 71,-634. As already explained, however, the EPA’s interpretation does not override an express command but rather resolves an ambiguity. Id. at 71,635-36. In commending the flexibility afforded, the EPA merely offered one more reason why its interpretation of the ambiguous statutory language is reasonable.
V. New Source “Offset” Credit for Past Emission Reductions
CAA section 172(b) requires that each State containing a nonattainment area submit a nonattainment SIP meeting the requirements of section 172(c) pursuant to a schedule set by the EPA but not later than three years after a nonattainment area is so designated. 42 U.S.C. § 7502(b), (c). Section 172(c)(5) of the Act requires that each nonattainment area SIP “shall require permits for the construction and operation of new or modified major stationary sources anywhere in the nonattainment area, in accordance with section 7503 of [Title 42].” Id. § 7502(c)(5). Section 173 sets out the permitting process, known as “New Source Review” (NSR), in greater detail, providing that a permit may be issued only if, inter alia, (1) the permitting agency has determined that by the time the source begins operation, sufficient offsetting emissions reductions are obtained that the emission levels from the offsets and the plan provisions represent RFP from the pre-permit levels, id.
The Phase 2 Rule allows proposed new and modified sources to meet this offset requirement using credits from sources that shut down or curtailed operations as long ago as 1977. 70 Fed.Reg. at 71,699 (to be codified at 40 C.F.R. § 51.165). The EPA has long allowed emissions reductions occurring before a permit application to qualify as offset credits under specified circumstances. Before 1989, such pre-application emissions reductions could be offset only if the proposed source was “a replacement for the productive capacity represented by the proposed offset credit.” Requirements for Implementation Plans; Air Quality New Source Review, 54 Fed. Reg. 27,286, 27,290 (June 28, 1989).
CAA section 307(b), which governs judicial review of a rulemaking under the Act, requires that “[a]ny petition for review ... shall be filed within sixty days from the date notice of such promulgation ... appears in the Federal Register.” 42 U.S.C. § 7607(b)(1). As already noted, the EPA has allowed emission reductions from preapplication source shutdowns and curtailments to qualify as NSR offset credits since at least 1989. See 54 Fed.Reg. at 27,292. Thus, the deadline for filing a petition for review of section 51.165(a)(3)(ii)(C) insofar as it authorizes offset credits for pre-permit emission reductions is long since past and the court lacks jurisdiction to review it. See Motor & Equip. Mfrs. Ass’n v. Nichols, 142 F.3d 449, 460 (D.C.Cir. 1998) (section 7607(b)(1) “filing period is jurisdictional in nature, and may not be enlarged or altered by the courts” (internal quotation marks omitted)). Nonetheless, the NRDC contends that the EPA “reopened” the 1989 offset policy so as to make its challenge timely. We disagree.
“The reopening doctrine allows an otherwise stale challenge to proceed because ‘the agency opened the issue up anew,’ and then ‘reexamined ... and reaffirmed its [prior] decision.’ ” P & V Enters. v. U.S. Army Corps of Eng’rs, 516 F.3d 1021, 1023-24 (D.C.Cir. 2008) (quoting Pub. Citizen v. Nuclear Reg. Comm’n, 901 F.2d 147, 150-51 (D.C.Cir. 1990)) (internal quotation marks omitted). In this case, the EPA did not expressly reopen the issue of offsets for pre-application emission reductions. In its proposed rule, the EPA offered two alternative amendments to section 51.165(a)(3)(ii)(C), each of which eliminated the attainment demonstration requirement under certain circumstances. See Prevention of Significant Deterioration (PSD) and Nonattainment New Source Review (NSR), 61 Fed.Reg. 38,250, 38,-311-14 (July 23, 1996) (Proposed Rules). In the Phase 2. Rule, the EPA selected the less restrictive of the two alternatives.
Nor did the EPA constructively reopen the issue, as the NRDC contends. Under some circumstances an issue may be “deemed to have been constructively reopened even though it was not actually reopened” in a literal sense. Kennecott Utah Copper Corp. v. U.S. Dep’t of Interior, 88 F.3d 1191, 1214 (D.C.Cir. 1996). “A constructive reopening occurs if the revision of accompanying regulations ‘significantly alters the stakes of judicial review
We next address the NRDC’s objection to the specific NSR revision that is subject to review in this proceeding' — that the EPA erred in eliminating the attainment demonstration requirement. We agree with the NRDC that the EPA acted arbitrarily and capriciously when it did so.
In the 1989 rulemaking, the EPA imposed the approved attainment demonstration requirement in order to comply with CAA section 173(a)(1), which allows an NSR permit to issue only if
the permitting agency determines that—
(A) by the time the source is to commence operation, sufficient offsetting emissions reductions have been obtained, such that total allowable emissions from existing sources in the region, from new or modified sources which are not major emitting facilities, and from the proposed source will be sufficiently less than total emissions from existing sources allowed under the applicable implementation plan prior to the application for such permit to construct or modify so as to represent (when considered together with the plan provisions required under section 7502 of this title) reasonable further progress (as defined in section 7501 of this title);—
42 U.S.C. § 7503(a)(1)(A) (1989). The EPA concluded that the “essence of [this] provision is that a new source may be
VI. NSR Limits on Pollution from New and Modified Major Sources
Pursuant to the SIP NSR requirements of CAA Part D, supra pp. 1263-64, the Phase 2 Rule accords a State three years to develop and submit an approvable non-attainment major NSR program for the 8-hour NAAQS. 70 Fed.Reg. at 71,672. In
In 1979, the EPA codified in its regulations a three year-old “Emission Offset Interpretative Ruling” as Appendix S to 40 C.F.R. Part 51 and directed that Appendix S was to “govern[] permits to construct and operate applied for before the deadline for having a revised SIP in effect that satisfies Part D.” Approval and Promulgation of Implementation Plans; Statutory Restriction on New Sources Under Certain Circumstances for Nonattainment Areas, 44 Fed.Reg. 38,471, 38,473 (July 2, 1979) (codified at 40 C.F.R. § 52.24(c) (1979) (now § 52.24(k))); see Emission Offset Interpretative Ruling, 44 Fed.Reg. 3274 (Jan. 16, 1979) (codifying interpretive ruling in regulations). In so applying the interpretive rule, the EPA allowed a non-attainment area to avoid, during the period before the SIP was due, the statutory ban on all major source construction or modification in any nonattainment area not subject to a SIP that “me[t] the requirements of Part D (relating to nonattainment areas).” See Clean Air Act Amendments of 1977, Pub.L. No. 95-95, § 108(b), 91 Stat. 685, 694 (Aug. 7, 1977) (establishing construction ban) (1977 CAA Amendments). The EPA noted at the time that the Congress had similarly adopted the rule (“as may be modified by rule of the Administrator”) to govern NSR during the interim period from enactment of the 1977 CAA amendments until July 1, 1979, when the statutory ban was to take effect. 44 Fed. Reg. at 38,472; 1977 CAA Amendments § 129(a)(1), 91 Stat. at 745 (adopting interpretive rule for interim before ban) (Aug. 7, 1977). The Congress eliminated the construction ban in 1990. Clean Air Act, Amendments, Pub.L. No. 101-549, § 101(c), 104 Stat. 2399, 2408 (1990).
In 1980, the EPA “clarif[ied]” Appendix S to limit to eighteen months the period during which it governed NSR in a qualifying nonattainment area. Approval and Promulgation of Implementation Plans; Statutory Restriction on New Sources Under Certain Circumstances for Nonattainment Areas, 45 Fed.Reg. 65,209 (Oct. 2, 1980) . Since that time the EPA has continued to apply Appendix S’s NSR requirements in the interim after an area’s nonattainment designation and before implementation of a revised SIP. Thus, after the Congress amended the Act in 1990—
Since Appendix S was formally codified in 1979, section VI thereof has contained— unchanged — an exemption from section IV. A’s permitting requirements for an area whose attainment date had not passed if the source satisfied two conditions:
In such cases, a new source which would cause or contribute to an NAAQS violation may be exempt from the Conditions of Section IVA. so long as the new source [1.] meets the applicable SIP emission limitations and [2.] will not interfere with the attainment date specified in the SIP under Section 110 of the Act.
44 Fed.Reg. at 3285 (codified at Appendix S, § VI); cf. 40 C.F.R. pt 51, app. S., § VI (2006) (same). In the Phase 2 Rule, the EPA added a third condition so that the reformulated provision now exempts new sources from the permitting requirements in section IV.A “if the conditions in paragraphs VI.A through C are met,” namely:
A. The new source meets the applicable SIP emission limitations.
B. The new source will not interfere with the attainment date specified in the SIP under section 110 of the Act.
C. The Administrator has determined that conditions A and B of this section are satisfied and such determination is published in the Federal Register.
70 Fed.Reg. at 71,704 (codified at 40 C.F.R. pt 51, app. S., § VI (2009)). The EPA further eliminated the 18-month limit on the applicability of Appendix S (including section VI) to a pre-SIP nonattainment area. 70 Fed.Reg. at 71,677; see 40 C.F.R. § 52.24(k) (2009).
As noted above, petitioners NRDC and New Jersey challenge the EPA’s authority generally to exempt an area from Appendix S’s permitting requirements and specifically the EPA’s removal of the 18-month limit. We address each in turn.
First, we consider the general challenge to the EPA’s exemption authority and conclude that it is time-barred. Under CAA section 307(b), any objection to the exemption policy was required to be raised in a petition for review “filed within sixty days from the date notice of [its] promulgation ... appears in the Federal Register,” 42 U.S.C. § 7607(b)(1). In this case the triggering date was July 2, 1979, when the EPA published its final rule promulgating 40 C.F.R. § 52.24(c) (1979) (now 52.24(k)), which directed that “[t]he Emission Offset Interpretative Ruling, 40 CFR Part 51, Appendix S” — which, as then codified, contained the exemption provision in section VI, 44 Fed.Reg. at 3285 — “governs permits to construct and operate applied for before the deadline for having a revised SIP in effect that satisfies Part D.” 44 Fed.Reg. at 38,473 (codified at 40 C.F.R. § 52.24(c) (1979) (now 52.24(k))). It was on that date that the EPA unequivocally asserted its authority to exempt new sources from permitting requirements under section VI. Thus, the petitioners’ challenge to such authority in this case comes almost thirty years late and we are precluded from considering it. See Motor & Equip. Mjrs. Ass’n, 142 F.3d at 460. Nonetheless, the petitioners again (as with the emission offset authority issue treated supra ) seek to circumvent the statutory time limit by invoking the reopening doctrine. Once again their attempt is unavailing.
The petitioners contend the EPA implicitly reopened the question of its exemption authority because during the rulemaking,
The petitioners also argue that the EPA constructively reopened the entire exemption provision “by dramatically expanding its scope and effect” when it eliminated the 18-month limit on Section VI exemptions. NRDC Br. at 41(citing Kennecott, 88 F.3d at 1226-27); see also NRDC Reply Br. at 18. The extension of the exemption term, however, did not “ ‘significantly alter[ ] the stakes of judicial review’ as the result of a change that ‘could have not been reasonably anticipated.’ ” Sierra Club v. EPA 551 F.3d at 1025 (quoting Kennecott, 88 F.3d at 1227; Envtl. Def., 467 F.3d at 1334). In fact, when first codified in 1979, the interpretive ruling lacked such a limit — yet its general exemption authority went unchallenged. Further, an exemption from NSR for even 18 months, if unlawful, seems worth challenging in its own right — as it could have been when the 18-month limit was added in 1980. To the extent that the EPA’s removal of the limit extends the exemption period, the extension is subject to direct challenge in this proceeding and we next address the petitioners’ challenge thereto.
The petitioners contend that the EPA’s elimination of the 18-month limit on NSR exemptions violates CAA section 172(e), the Act’s “anti-backsliding” provision. Section 172(e) provides that if the EPA “relaxes a national primary ambient air quality standard,” it must “promulgate requirements applicable to all areas which
The EPA offers three defenses of its revision. First, because the EPA established the time limit to allow a newly-designated nonattainment area a reasonable time to develop a SIP before the statutory construction ban applied, see 45 Fed.Reg. at 65,209, the EPA contends that it reasonably removed the 18-month limitation after the Congress repealed the new source construction ban in 1990. The EPA might have done so but for section 172(e)’s unequivocal backsliding constraint, which plainly prohibits a “less stringent” NSR control — precisely what the revision produced. Second, the EPA asserts “there is no basis to speculate” that it will grant waivers for the entire period before SIP approval because “it ‘would be highly disinclined to grant a waiver where the SIP submission deadline has passed and EPA had not received the required submission.’ ” EPA Br. at 102-03 (quoting 72 Fed.Reg. at 31,745-46). We do not speculate, however, in concluding that, notwithstanding the EPA’s promised discretionary restraint, the revised section VI will produce some waivers lasting beyond the previously prescribed 18-month period and thus impose a control less stringent than before. This result contravenes section 172(e). Nor are we persuaded by the EPA’s third argument, that the revision’s new, third “pre-condition” — that the EPA determine that the existing two pre-conditions (satisfaction of applicable SIP emission limitations and non-interference with SIP’s attainment date) have been met and publish the determination in the Federal Register — “tightened” Part Vi’s requirements. EPA Br. at 103. The new precondition simply formalized and made explicit what was already implicitly required — that the EPA find the existing two pre-conditions satisfied. Thus, the additional pre-condition produced no “tightening” effect; on the contrary, it did nothing to counteract the indisputably relaxing effect of removing the 18-month limit.
VII. Baton Rouge’s Reformulated Gasoline Requirement
The Chamber of Greater Baton Rouge and affiliated petitioners (Chamber) contend the EPA arbitrarily and capri
CAA section 211(k)(l) authorizes the EPA to “promulgate regulations ... establishing requirements for reformulated gasoline to be used in gasoline-fueled vehicles in specified nonattainment areas.” 42 U.S.C. § 754500(1). Section 211(k)(5) makes unlawful “[t]he sale or dispensing by any person of conventional gasoline to ultimate consumers in any covered area”— necessitating the use of reformulated gasoline instead. Id. § 7545(k)(5)(A). Section 211(k)(10), in turn, designates as a “covered area” each of nine specific, high ozone areas and further provides: “Effective one year after the reclassification of any ozone nonattainment area as a Severe ozone non-attainment area under section 7511(b) of this title, such Severe area shall also be a ‘covered area’ for purposes of this subsection.” Id. § 7545(k)(10)(D).
In 1991, the EPA classified Baton Rouge as a “serious” ozone nonattainment area under the 1-hour standard. On April 24, 2003, the EPA reclassified Baton Rouge as “severe,” effective June 23, 2003, pursuant to the bump-up provision, CAA § 181(b)(2), 42 U.S.C. § 7511(b)(2), because Baton Rouge failed to reach attainment by its November 15, 1999 attainment date. Notice of Withdrawal of October 2, 2002, Attainment Date Extension, Determination of Nonattainment as of November 15, 1999, and Reclassification of the Baton Rouge Ozone Nonattainment Area, 68 Fed.Reg. 20,077 (Apr. 24, 2003) (effective June 23, 2003). At that time, the EPA advised that “under Section 211(k) of the Act the use of reformulated gasoline (RFG) will be required in the Baton Rouge area beginning one year from the effective date of this rule,” that is, as of June 23, 2004. Id. at 20,080. On April 30, 2004, the EPA designated Baton Rouge as nonattainment under the 8-hour standard and classified it as “marginal,” effective June 15, 2004. Air Quality Designations and Classifications for the 8-Hour Ozone National Ambient Air Quality Standards; Early Action Compact Areas With Deferred Effective Dates, 69 Fed.Reg. 23,858, 23,907 (Apr. 30, 2004).
The Chamber filed a request for extension of the deadline to commence using RFG or waiver of the RFG requirement, which the EPA denied in a letter dated May 5, 2004. The Chamber then petitioned the United States Court of Appeals for the Fifth Circuit for review of the denial and the Fifth Circuit stayed the RFG deadline on June 18, 2004. On August 2, 2004 the Fifth Circuit granted a joint motion to stay its proceedings “pending the outcome of the administrative decision making process,” with the RFG deadline stay to remain in effect during remand. City of Baton Rouge v. EPA, No. 04-60408 (5th Cir. Aug. 2, 2004).
In the Phase 2 Rule, the EPA concluded that an area such as Baton Rouge, which automatically became a “covered area” (subject to the RFG requirement) on the one-year anniversary of its bump-up to “severe,” should remain subject to the RFG requirement notwithstanding its classification to a Iess-than-severe status under the 8-hour standard and the subsequent revocation of the 1-hour standard:
First, the Chamber contends that at Chevron step 1 Baton Rouge never became a “covered area” because the plain and unambiguous language of the statutory definition requires that a “covered area” be “a ‘Severe area’ that remains severe ‘one year after the reclassification,’ ” Chamber Br. at 15 (quoting CAA § 211(k)(10)(D), 42 U.S.C. § 7545(k)(10)(D)), that is, on June 23, 2004, on which date Baton Rouge was no longer a severe area as it had become a marginal area on June 15, 2004. The EPA does not quibble with the Chamber’s interpretation of the statutory language to require that the area remain classified as “severe” on the one-year anniversary of the reclássification. See EPA Br. at 111 (“[Ojnce an area is reclassified as ‘severe,’ the only other precondition to becoming ‘covered’ is that the area remain in severe nonattainment status for one year.”) (emphasis in original). The EPA points out, however, that as of the one-year anniversary of the bump-up — June 23, 20004 — Baton Rouge was not only a marginal area under the 8-hour standard but was also a severe area under the 1-hour standard, which was not revoked until June 15, 2005, almost a year later. See Phase 1 Rule, 69 Fed.Reg. at 23,954 (“We will revoke the 1-hour standard in full, including the associated designations and classifications, 1 year following the effective date of the designations for the 8-hour NAAQS.”). Thus, the EPA reasonably determined that under the plain language of the statute, Baton Rouge was a severe area as of June 23, 2004 and became a “covered area” on that date.
The Chamber also asserts the EPA’s interpretation falters at Chevron step 2 because the Agency unreasonably relied on “the very same provisions it referred to in the Phase 1 Rule at 69 Fed.Reg. 23972,” which provisions, the Chamber maintains, “did not support the Phase 1 Rule, nor do they support the imposition of RFG.” Chamber Br. at 22-23 (citing 70 Fed.Reg. at 71,686). The Chamber examines each of the statutes cited in the Phase 1 Rule and asserts, correctly, that none of them directly relates to the RFG requirement. See id. at 23-24. The Chamber makes too much, however, of the EPA’s citation to the Phase 1 Rule. The EPA was simply referring readers “[f]or further discussion of the reasoning behind anti-backsliding provisions in the Phase 1 Rule” because the Agency also relied on the anti-backsliding rationale for its interpretation of the “covered area” definition in the Phase 2 Rule.
Finally, the Chamber contends the EPA was arbitrary and capricious in not making a specific determination that RFG would “protect the public health” in Baton Rouge and asserts that in fact RFG will interfere with the area’s progress toward attainment, thereby harming the public health. The Chamber first asserts that the EPA was required by CAA section 109(b)(1) to make a specific finding that requiring RFG “protects the public health” of Baton Rouge, citing 42 U.S.C. § 7409(b)(1) (“National primary ambient air quality standards, prescribed under subsection (a) of this section shall be ambient air quality standards the attainment and maintenance of which in the judgment of the Administrator, based on such criteria and allowing an adequate margin of safety, are requisite to protect the public health.”). The Chamber further argues that requiring RFG in Baton Rouge will interfere with the area’s attainment because studies have shown RFG increases NOx levels and Baton Rouge’s SIP strategy for reducing ozone relies largely on reducing NOx (and not VOCs). By interfering with attainment, the Chamber contends, RFG in fact endangers the public health. As an initial matter, the Chamber’s objections based on harm to public health and interference with RFP and attainment are forfeited because they were not raised before the Agency. See CAA § 307(d)(7)(B), 42 U.S.C. § 7607(d)(7)(B) (“Only an objection to a rule or procedure which was raised with reasonable specificity during the period for public comment (including any public hearing) may be raised during judicial review.”). To the extent Baton Rouge argues that RFG will not improve the public health, the EPA adequately addressed these objections and reasonably determined they may best be resolved through individual waiver requests.
In the Phase 2 Rulemaking, the Baton Rouge Clean Air Coalition asserted that RFG use in Baton Rouge would “provide no measurable benefits for NOx,” less than 2 tons per day of VOC reductions, and “an ozone benefit ... of around 0.26 ppb,” and asked whether these data “qualify as an ‘absurd result’ and [would] be subject to consideration for waiver.” Letter from Mike D. McDaniel, Executor Director, Baton Rouge Clean Air Coalition to U.S. EPA at 4 (July 30, 2003); see Phase 2 Rule, 70 Fed.Reg. at 71,687-88. In response, the EPA noted that Baton Rouge had “submitted requests for an RFG waiver and for a waiver of the RFG oxygen content requirement, which are currently before the Agency.” 70 Fed.Reg. at 71,-688. Based on its determination that “the transition to the more protective 8-hour standard should [not] result in less restrictive requirements for RFG than would apply if the EPA had never revised the 1-hour standard,” the EPA advised that “[t]he appropriate mechanism to address Baton Rouge’s concerns is ... in the context of Baton Rouge’s petitions for relief
VIII. Conclusion
In sum, we hold (1) the Phase 2 Rule violates the Act by allowing participation in the NOx SIP Call to satisfy the requirement that a nonattainment area mandate such reductions as can be achieved by the application of RACT, (2) the EPA acted arbitrarily when it eliminated the requirement that an attainment demonstration be approved for an area before a new source would be allowed to use a past emission reduction to offset new emissions, and (3) the elimination of the 18-month time limit for NSR waivers under Appendix S violates the anti-backsliding provision of the Act. In light of the likelihood the EPA will be unable to cure the backsliding inherent in the removal of the 18-month time limit, we vacate that provision of the Phase 2 Rule and remand it to the EPA. See Ill. Pub. Telecomms. Ass’n v. FCC, 123 F.3d 693, 693 (D.C.Cir. 1997) (“When this court remands a rule ... with little or no prospect of the rule’s being readopted upon the basis of a more adequate explanation of the agency’s reasoning, the practice of the court is ordinarily to vacate the rule”). We remand to the EPA without vacatur the other two provisions of the Phase 2 Rule we hold invalid. We defer consideration of the Phase 2 Rule and Reconsideration Notice insofar as they relate to the CAIR program, and we deny the petitions in all other respects.
So ordered.
. The affiliated petitioners are the West Baton Rouge Chamber of Commerce, the Iberville Parish Chamber of Commerce, and the Louisiana Oil Marketers and Convenience Store Association.
. The second and third challenges are to the EPA's statements in the preamble to the final rule. The statements constitute reviewable final agency action, see CAA § 307(b)(1), 42 U.S.C. § 7607(b)(1), as they represent "the consummation of the agency’s decisionmaking process and ... establish[ ] rights and obligations or create[] binding legal consequences." National Res. Def. Council v. EPA, 559 F.3d 561, 564 (D.C.Cir. 2009). The EPA’s statements as to how it will implement the RACT requirement are not conjectural and their terms are clear, so it is fair to infer that the EPA intended the statements to create binding legal consequences. See Kennecott Utah Copper Corp. v. Dep't of Interior, 88 F.3d 1191, 1222-23 (D.C.Cir. 1996).
. An area may in some circumstances substitute a combined reduction in emissions of VOCs and NOx for the fixed percentage reduction of VOCs required by CAA § 182(c)(2)(B). See 42 ' U.S.C. § 7511a(c)(2)(C). Although CAA § 182(b)(1)(A) applies by its terms only to an area in moderate nonattainment, and § 182(c)(2)(B) only to an area classified in serious nonattainment, § 182(c), (d), and (e) apply those requirements to areas in a greater degree of nonattainment. See id. § 7511 a(c)(e).
. The statute permits a reduction in "an amount less than 3 percent of such baseline emissions each year, if the State demonstrates to the satisfaction of the Administrator that the plan reflecting such lesser amount includes all measures that can feasibly be implemented in the area, in light of technological achievability.” CAA § 182(c)(2)(B)(ii), 42 U.S.C. § 7511 a(c)(2)(B)(ii).
. Section 182 does not provide for a specific VOC reduction for a moderate area following the initial six-year 15% reduction period. Accordingly, thereafter a moderate area is subject to the general requirement in CAA section 172(c)(2) that "plan provisions shall require reasonable further progress,” 42 U.S.C. § 7502(c)(2).
. The EPA apparently meant section 172(c), see supra note 5; section 172(e) is the anti-backsliding provision, see infra pp. 1270-71.
. "Ozone, an essential presence in the atmosphere's stratospheric layer, is dangerous at ground level" and "is formed by the chemical reaction of nitrogen oxides ('NOx') with any of a number of volatile organic compounds ('VOCs'), in the presence of sunlight.” S. Coast Air Quality Mgmt. Dist. v. EPA, All F.3d 882, 887 (D.C.Cir. 2006).
. Section 173(a)(1)(A) requires that the permitting agency determine! 1 that—
(A) by the time the source is to commence operation, sufficient offsetting emissions reductions have been obtained, such that total allowable emissions from existing sources in the region, from new or modified sources which are not major emitting facilities, and from the proposed source will be sufficiently less than total emissions from existing sources (as determined in accordance with the regulations under this paragraph) prior to the application for such permit to construct or modify so as to represent (when considered together with the plan provisions required under section 7502 of this title) reasonable further progress (as defined in section 7501 of this title);....
42 U.S.C. § 7503(a)(1)(A).
. Section 173(a) also requires that (1) the new source owner or operator has demonstrated that all of its other major stationaiy sources in the State are subject to and in (or scheduled for) compliance with applicable emission limitations and standards; (2) the Administrator has not determined the implementation plan applicable to the attainment area site of the new source is not being adequately implemented; and (3) an analysis of alternatives demonstrates that "benefits of the proposed source significantly outweigh the environmental and social costs imposed as a result of its location, construction, or modification.” 42 U.S.C. § 7503(a)(3)-(5).
. More generally, the Act requires that all SIPs, even those for attainment areas, include regulation of new and modified sources "as necessary to assure that national ambient air quality standards are achieved, including a permit program as required in parts C and D of this subchapter.” CAA § 110(a)(2)(C), 42 U.S.C. § 7410(a)(2)(C).
. The pre-1989 regulation provided:
Emissions reductions achieved by shutting down an existing source or permanently curtailing production or operating hours below baseline levels may be credited, provided that the work force to be affected has been notified of the proposed shutdown or curtailment. Source shutdowns and curtailments in production or operating hours occurring prior to the date the new source application is filed generally may not be used for emissions offset credit. However, where an applicant can establish that it shut down or curtailed production after August 7, 1977, or less than one year prior to the date of permit application whichever is earlier, and the proposed new source is a replacement for the shutdown or curtailment credit for such shutdown or curtailment may be applied to offset emissions from the new source.
. Alternative 1 conditioned using offset credits upon an area being "current with part D ozone nonattainment planning require-merits”; Alternative 2, which the EPA selected, did not. Phase 2 Rule, 70 Fed.Reg. at 71,673.
. In light of this conclusion, we need not consider the NRDC's alternative contention that elimination of the requirement violates section 172(e) of the Act, 42 U.S.C. § 7502(e).
. Section 211(k) defines "conventional gasoline” as "any gasoline which does not meet specifications set by a certification under [section 211 (k) ]” as "reformulated gasoline.” 42 U.S.C. § 7545(k)(10)(E)-(F).
. The EPA stated it was "reserving for future consideration what RFG requirements, if any, should apply to the nine mandatory areas and the bump-up areas covered by this final rule when they are redesignated to attainment for the 8-hour NAAQS.” 70 Fed.Reg. at 71,687. The EPA further noted its determination did “not change or affect any discretion EPA may otherwise have under the RFG provisions to modify or remove RFG requirements.” Id. at 71,686.
. The Chamber argues that this reasoning is foreclosed because the EPA itself "stated that the 8-hour NAAQS is the 'relevant' standard.” Chamber Br. at 18 (quoting Phase 1 Rule, 69
. The Chamber also objects in particular to the EPA’s reliance on CAA section 172(e), the anti-backsliding provision. See Chamber Br. at 23-24; Chamber Reply Br. at 2-3. The Chamber argues section 172(e) applies only when the EPA "relaxes” a standard and that, in promulgating the 8-hour standard, the EPA in fact strengthened, rather than relaxed, the standard. The EPA’s reliance on section 172(e) in the Phase 1 Rule, however, supported its specific policy against backsliding in converting to the 8-hour standard notwithstanding the 8-hour standard is stricter (not more relaxed) than the one-hour standard. We have already upheld this policy as reasonable. See S. Coast, 472 F.3d at 900.
. As the EPA notes, the Chamber submitted material originating in the Fifth Circuit proceeding to support these objections but the material was not submitted during the proceeding before the Agency. See EPA Br. at 116.

I join the court’s opinion regarding challenges to the Phase 2 Rule
I.
The principles underlying the reopening doctrine are well-established. It is only their application that may obfuscate the reality of what an agency regulatory action entails. This is the situation here.
A.
Offset credits. The Phase 2 Rule allows new and modified sources to meet emissions offset requirements under CAA § 173(c), 42 U.S.C. § 7503(c), by using credits from sources that shut down or curtailed operations as long ago as August 7, 1977. See 40 C.F.R. § 51.165(a)(3)(ii)(C)(l ){ii); Op. at 1264-65. Contrary to the court’s suggestion, this court’s opinion in Kennecott makes clear that the fact that the “basic regulatory scheme remains unchanged,” Op. at 1266, is not dispositive of whether an issue has been constructively reopened. See Kennecott, 88 F.3d at 1219. Analyzing the reopening doctrine at that level of generality begs the question. If “adding new terms to [an] old rule” can result in reopening, see id., then so can removing old terms from an old rule, at least where those old terms were an important part of the underlying regulatory scheme. Furthermore, Kennecott also makes clear that the question whether the stakes are “quantitatively different,” Op. at 1266-67, does not turn on whether the petitioner or another failed to object to a different change earlier. See Kennecott, 88 F.3d at 1226-27. Although a 1989 Rule made it easier to use pre-application offset credits, see Requirements for Implementation Plans, Air Quality New Source Review, Final Rule, 54 Fed.Reg. 27,286, 27,292 (June 28, 1989) (“1989 Rule”), the concomitant addition of the attainment demonstration requirement mitigated the impact of the change and may well have meant it was not “worth challenging,” Kennecott, 88 F.3d at 1227, the regime as a whole. However, once EPA eliminated the attainment demonstration requirement and failed to replace it with a comparable substitute, the need for a challenge by environmental groups such as the NRDC arose because EPA had “dramatically expanded authority to use [pre-application offset] credits,” NRDC Br. at 44. This change meant that “a major new pollution source [may] add substantial new emissions to a nonattainment area without any contemporaneous offsets, even when the state has no plan for meeting standards and no idea of what total reductions are needed to attain standards.” Id. at 45.
Both EPA’s and the court’s analysis show that a constructive reopening occurred. See Op. at 1266-67. In announcing the 1989 Rule, EPA stated that to comply with the reasonable further progress (“RFP”) requirement of CAA § 173(a)(1)(A), 42 U.S.C. § 7503(a)(1)(A), the restriction on pre-application offset credit was “necessary both to assure RFP and to guarantee that a new source does
On the merits, the NRDC persuasively contends that “EPA’s final rule ... unlawfully permits total allowable emissions after the new source starts operating to be higher than emissions from existing sources before the new source applied for its permit.” NRDC Br. at 42-43. The Phase 2 Rule’s allowance of offset credit for pre-application shutdowns and curtailments is contrary to the plain text of the CAA and fails under Chevron step one. Chevron U.S.A. Inc. v. Natural Res. Def. Council, Inc., 467 U.S. 837, 842-43, 104 S.Ct. 2778, 81 L.Ed.2d 694 (1984). Section 173(a)(1)(A) requires that “sufficient offsetting reductions” shall be obtained “such that total allowable emissions from existing sources in the region, from new or modified sources which are not major emitting facilities, and from the proposed source will be sufficiently less than total emissions from existing sources ... prior to the application for such permit to construct or modify so as to represent ... reasonable further progress.” 42 U.S.C. § 7503(a)(1)(A). Section 173(c)(1) requires that offsets come from “an equal or greater reduction, as applicable, in actual emissions of such air pollutant from the same or other sources in the area.” Id. § 7503(c)(1) (emphasis added); see also H.R.Rep. No. 101-490, pt. 1 (1990) (referring to reductions in “actual emissions”). Under the Phase 2 Rule, new and modified major sources may claim offset credit from reductions in emissions resulting from the shutdown or curtailment of operations from more than three decades ago. The absence of any meaningful time limit means the Rule is inconsistent with CAA § 173(c)(l)’s requirement that new sources’ emissions “shall be offset” by an equal or greater reduction in “actual emissions,” 42 U.S.C. § 7503(c)(1). Congress is presumed, absent any indication to the contrary, to have intended the ordinary meaning of the word “actual,” as “existing or occurring at the time,” Merriam Webster’S Collegiate Dictionary (10th ed. 1993) (emphasis added); accord Webster’s Third New Int’l Dictionary (1993). See Engine Mfrs. Ass’n v. S. Coast Air Quality Mgmt. Dist., 541 U.S. 246, 252, 124 S.Ct. 1756, 158 L.Ed.2d 529 (2004). Congress has given no indication in the
EPA offers that because the Phase 2 Rule requires the old offsets to be included in the area’s emissions inventory, allowance of pre-application offset credits is consistent with the requirement in CAA § 173(a)(1)(A), 42 U.S.C. § 7503(a)(1)(A), that offsets ensure reasonable further progress toward attainment. See Phase 2 of the Final Rule to Implement the 8-Hour Ozone National Ambient Air Quality Standard, Final Notice of Reconsideration, 72 Fed.Reg. 31,727, 31,742/3 (June 8, 2007) (“Final Notice of Reconsideration”). But using decades-old emissions in an accounting exercise cannot render those emissions “actual” as that word is commonly understood. Likewise, EPA offers that because “[f]rom an air quality planning perspective” emissions from the previously shutdown or curtailed sources had impacted the area’s designations as nonattainment, they are “actual emissions reductions.” Phase 2 Rule, 70 Fed.Reg. at 71,677; see also Final Notice of Reconsideration, 72 Fed.Reg. at 31,742/3. But that emissions were “actual” as long ago as the 1970s does not mean they continue to meet the common understanding of “actual” years later when a source applies for a construction or modification permit.
Because the flaws in this part of the Phase 2 Rule, see 40 C.F.R. § 51.165(a)(3)(ii)(C)(I ){ii), cannot be remedied by further explanation by EPA, it must be vacated. See Allied-Signal, Inc. v. U.S. Nuclear Reg. Comm’n, 988 F.2d 146, 150-51 (D.C.Cir. 1993). To what extent the court’s holding that elimination of the requirement of an approved attainment demonstration is arbitrary and capricious under CAA § 307(d)(9)(A), 42 U.S.C. § 7607(d)(9)(A), Op. at 1266-67, will result in a different outcome than vacatur remains to be seen upon remand.
B.
NSR waiver authority. Section 110(a)(2)(C), 42 U.S.C. § 7410(a)(2)(C), does not specify what NSR requirements apply in the period between an area’s designation as nonattainment and approval of its NSR state implementation plan (“SIP”). Prior to promulgating the Phase 2 Rule, EPA had filled this statutory gap by retaining Appendix S’s interim NSR regime, which by its terms could apply for only 18 months. Given the limited duration of its effect, the previous regulation “may not have been worth challenging,” Kennecott, 88 F.3d at 1227. However, EPA’s decision to eliminate the 18-month limitation “alter[ed] the stakes of judicial review,” id. By parity of reasoning, if there was a reopening in Kennecott where industry petitioners faced a new requirement creating the possibility of the imposition of additional penalties, then there was a constructive reopening where EPA’s change meant NSR controls could be postponed indefinitely, thereby dramatically changing the scope and effect of the waiver provision.
Additionally, EPA constructively reopened the issue of its NSR waiver authority when it proposed to remove the general waiver provision in Appendix S and replace it with a “transitional” program in which waivers would be available in only a limited set of nonattainment areas. See Proposed Rule to Implement the 8-Hour Ozone National Ambient Air Quality Standard, 68 Fed.Reg. 32,802, 32,846-48 (June 2, 2003) (“NPRM”). EPA has described the proposal as a “major rewrite of [A]ppendix S.” Phase 2 Rule, 70 Fed.Reg. at 71,674. In explaining the 2003 proposal, EPA stated “we do not believe that areas
On the merits, the challenge by the NRDC and the State of New Jersey to EPA’s authority to exempt new sources from the interim NSR permitting requirements is unpersuasive. They contend that “[w]here Congress has intended to allow exceptions to NSR requirements, it has expressly said so,” NRDC Br. at 38 (citing, inter alia, CAA § 173(a)(1)(B), 42 U.S.C. § 7503(a)(1)(B), excepting economic development zones). However, EPA persuasively responds that the waivers are the product of EPA’s gap-filling authority. See Chevron, 467 U.S. at 843^5, 104 S.Ct. 2778. In exercising that authority, EPA established requirements “substantially similar to the requirements of part D,” CAA § 171 et seq., 42, U.S.C. § 7501 et seq., although not identical to the “major NSR” program under Part D. See Phase 2 Rule, 70 Fed.Reg. at 71,678/1. The “minor NSR” program under CAA § 110(a)(2)(C) calls for “regulation of the modification and construction of any stationary source within the areas covered by the plan as necessary to assure that [NAAQS] are achieved.” 42 U.S.C. § 7410(a)(2)(C) (emphasis added). EPA thus could reasonably conclude that the interim NSR requirements are inapplicable when the exemption conditions are met. In those instances, a waiver would be available only if the new source’s emissions would not interfere with timely attainment, see 40 C.F.R. pt. 51, app. S, § VI, making additional NSR requirements unnecessary.
Although EPA had authority to provide waivers on a case-by-case basis where a waiver would not interfere with timely attainment, I concur in holding that EPA’s elimination of the 18-month limitation violates the anti-backsliding provision in CAA § 172(e), 42 U.S.C. § 7502(e), see Op. at 1270-71.
II.
The Clean Data Policy, originally published in 1992 and revised in 1995, excuses state planning requirements relating to RFP, attainment demonstrations, and contingency measures for areas attaining the NAAQS but not yet redesignated as attainment areas. In commenting in 2003 on the proposed codification of this statutory interpretation, environmental groups, including the NRDC, stated that the “EPA cannot authorize states to simply drop sub-part 2 measures when the area is meeting either [the 1-hour or 8-hour] standard.” Clean Air Task Force, et al., Comments at 48. By arguing that “[t]he [CAA] allows states to move mandated controls to a maintenance contingency plan, [CAA § 175A, 42 U.S.C. § 7505a], but only after the area has been redesignated to attainment,” id. (emphasis added), environmental groups put EPA on notice of its view that until an area is designated as being in attainment, a state plan must continue to contain the antecedent requirements, such as contingency measures, applicable in nonattainment areas.
Contrary to the court’s holding that the NRDC’s challenge to the contingency plan aspect of EPA’s Clean Data Policy is forfeited, Op. at 1272-73, the rulemaking rec
Nonetheless, although the NRDC’s challenge is properly before the court, it fails on the merits. Section 172(c)(9) provides that SIPs in nonattainment areas “shall provide for implementation of specific measures to be undertaken if the area fails to make reasonable further progress, or to attain the [NAAQS] by the attainment date applicable under this part.” 42 U.S.C. § 7502(c)(9) (emphasis added). The NRDC contends that “[t]he [Clean Data] [P]olicy waives mandatory pollution control requirements based solely on an area’s current air quality, without requiring the area to also show — as mandated by Congress — that it has met all of the [CAA]’s applicable requirements.... ” NRDC Br. at 34. However, EPA’s view that CAA §§ 172(c)(9) and 182(c)(9), 42 U.S.C. §§ 7502(c)(9), 7511a(c)(9), are written in a manner that ties the antecedent contingency measures to the requirements for RFP and an attainment demonstration, such that all are inapplicable upon attainment, see Phase 2 Rule, 70 Fed.Reg. at 71,645, is consistent with the plain text and to the extent there may be ambiguity, it is a reasonable interpretation. The Clean Data Policy requires that areas have “three consecutive years of clean air quality monitoring data demonstrating attainment of the ozone standard” before EPA can determine areas have attained. Memorandum from John S. Seitz, Director, Office of Air Quality Planning and Standards, EPA, to Various EPA Directors 5 (May 10, 1995). Also, if EPA determines an area covered by the Clean Data Policy has violated the NAAQS prior to formal designation of attainment, the Clean Data Policy no longer applies to that area. See 40 C.F.R. § 51.918.
