Opinion

WILLIAMS, Senior Circuit Judge:

The petitioners—environmental and community organizations—-contend that the Environmental Protection Agency has violated the Administrative Procedure Act and the Clean Air Act by modifying, without notice and comment, its prior understandings of how to measure a proposed transportation project’s impact on ambient levels of PM2.5 and PM10. (The first is particulate matter 2.5 micrometers or less in diameter; the second is particulate matter 10 micrometers or less in diameter.) The parties agree that the modification would, at the margin, make it less likely than before that a project would run afoul of various legal restrictions on the affected projects. As petitioners see it, the EPA’s new viewpoint violates the Clean Air Act’s substantive requirements.

For want of jurisdiction we do not reach the substance of either the APA or the Clean Air Act arguments. In the case of PM2.6, petitioners have shown no instance where the change would be likely to have any adverse effect on them or their members; they therefore lack standing. In the case of PM10, the EPA’s new provisions are not binding on the agency or affected parties and therefore do not constitute “final action” within the meaning of the Clean Air Act provision on which petitioners rely for our jurisdiction, 42 U.S.C. § 7607(b)(1).

Under the Clean Air Act, the EPA has established National Ambient Air Quality Standards (“NAAQS”) for various pollutants including PM2,B and PM10. To prevent uses of federal money that would take an area out of compliance with the NAAQS, the Act bars federal instrumentalities from supporting projects that would tend to do so. The Act directs federal agencies not to supply funds for any project that “does not conform” to the applicable State Implementation Plan (“SIP”) (required of states in order' to assure the implementation and maintenance of the NAAQS, 42 U.S.C. § 7410), and defines conformity to the SIP as including assurance that the project will not

(i)cause or contribute to any new violation of any [NAAQS] in any area;
(ii) increase the frequency or severity of any existing violation of any [NAAQS] in any area; or
(iii) delay, timely attainment of any [NAAQS]!...

42 U.S.C. § 7506(c)(1)(B).

EPA regulations governing “conformity” determinations for federally funded transportation plans possibly affecting PM2,5, PMjo, or carbon monoxide substantially replicate this language. 40 C.F.R. § 93.116. (A separate set of regulations applies to federal actions other than highways and mass transit. See Determining Conformity of General Federal Actions to State or Federal Implementation Plans, 58 Fed. Reg. 63,214 (Nov. 30, 1993).) To define the conformity requirement’s scope, the regulations employ the Act’s classifications of areas with respect to “attainment” of the standard for a particular pollutant. Under the Act, an area of a state that fails to comply with a given NAAQS is rated “non-attainment”; one that formerly did not comply but now does, but has yet to satisfy some transitional criteria, is designated “maintenance.” An area is in “attainment” if it not only meets the standard but is not subject to the qualifications that would land the area in the “maintenance” category 42 U.S.C. § 7407(d)(l)(A)(i)-(ii), (3)(E). The regulation applies conformity requirements only to areas designated “nonattainment” or “maintenance.” 40 C.F.R. § 93.116(a).

Congress charged the EPA Administrator, with the concurrence of the Secretary of Transportation, with promulgating “criteria and procedures for demonstrating and assuring conformity in the case of transportation plans, programs, and projects.” 42 U.S.C. § 7506(c)(4)(B). For CO and PM, the EPA created a so-called “hot-spot” analysis. It specified that project sponsors (typically state departments of transportation) should combine the baseline concentration with the expected increment resulting from the project, and compare the sum with the concentration permitted by the NAAQS. 40 C.F.R. § 93.123(c)(1); see also 75 Fed. Reg. 79,-370, 79,370/3-79,371/1.

In 2006, when the EPA first revised the hot-spot regulations to apply to PM2,6, the regulations said that the hotspot analysis “must be based on quantitative analysis methods” for projects of local air quality concern, including “[n]ew highway projects that have a significant number of diesel vehicles, and expanded highway projects that have a significant increase in the number of diesel vehicles.” 40 C.F.R. § 93.123(b)(1), (b)(1)®. But they also said that quantitative methods would not take effect “until EPA release[d] modeling guidance on this subject and announced] in the Federal Register that these requirements are in effect.” 40 C.F.R. § 93.123(b)(4). Until then, rather vaguely described “qualitative” methods were to prevail. In fact, and of some importance for our analysis, the mandate to use quantitative methods took effect only after a two-year grace period following the EPA’s issuance of the preferred methodology in December 2010. See 40 C.F.R. § 93.111(a)-(b); 75 Fed. Reg. at 79,370/2.

The EPA issued that guidance after employing notice and comment procedures specified by a settlement with environmental groups. See 75 Fed. Reg. 29,537, 29,-538/1; see also Joint Appendix (“J.A.”) 299-302. It announced the release in the Federal Register. See 75 Fed. Reg; at 79,-370/2. The Guidance essentially required a summing of monitored PM on a specified extreme day (for the baseline) with the modeled PM increment for a specified extreme day (for the future). See Transportation Conformity Guidance for Quantitative Hot-spot Analyses in PM2.6 and PM10 Nonattainment and Maintenance Areas (EPA-420-B-10-040, Dec. 2010) (“2010 Guidance”), available at nep-is.epa.gov/Exe/ZyPURL.cgi?Dock-ey=P1009HVH.TXT. (In some cases, the baseline was to be adjusted by an estimate of possible changes independent of the project. See 40 C.F.R. § 93.123(c)(2); 2010 Guidance at § 8.3.3.) If the total (called the design value) was lower than the NAAQS, the project conformed. The rules for PM2.6 and PMjo differed simply in their identification of the extreme days to be evaluated.
