Comments alleged typically which the timing in the EPA's proposed actions on the SIP submissions in relation to proposed FIPs was unlawful, unfair, or both equally. Some remarks claimed which the sequence of your EPA's actions is incorrect, unreasonable, or negative coverage. Various commenters asserted that as the EPA proposed FIPs (or, In line with some, promulgated FIPs, which is not factually suitable) before finalizing disapproval in the point out SIP submission, the EPA allegedly exceeded its statutory authority and overstepped the states' Major part in addressing The great neighbor provision beneath CAA part a hundred and ten.[244] EPA Response:
at 324. The court spelled out that “an upwind condition can `lead' to downwind nonattainment even if its emissions are usually not the but-for cause.” Id.

decision, held which the EPA need to evaluate air quality at the next downwind attainment day, including Marginal region attainment dates, in analyzing The idea with the EPA's denial of a petition below CAA part 126(b). Maryland,
Reviews condition that the EPA should not disapprove a SIP determined by details not accessible to states during enhancement in the SIP submissions or for the EPA throughout the interval statutorily allotted with the EPA to acquire remaining motion on SIP submissions. EPA Reaction:
A number of comments state that international emissions add to nonattainment and servicing receptors downwind, and these emissions are certainly not inside the jurisdiction on the states. They advocate for your EPA really should thinking about this when acting on SIP submissions. Some responses assert that, within the west, Intercontinental contributions are even higher than in eastern portions with the U.

As discussed further more in Portion III.B., in reaction to comments, the Company has also taken a more in-depth evaluate calculated ozone concentrations at checking internet sites in 2021 and 2022 with the purposes of informing the identification of more receptors in 2023. We discover There exists a foundation to contemplate certain web pages with elevated ozone concentrations that are not if not identified as receptors to get yet another kind of upkeep-only receptor offered the likelihood that ozone degrees above the NAAQS could persist at People areas through no less than 2023. We refer to these as violating-keep an eye on servicing-only receptors (“violating monitors”). For uses of the action, we use this information and facts only in a very confirmatory way for states which have been usually observed to get connected utilizing the modeling-centered methodology. The EPA intends to get individual motion to deal with states which are connected only to one or more violating-keep track of receptors.
approximately seven percent of full upwind point out contribution was dropped in accordance with the modeling underlying the August 2018 memorandum; in the EPA's 2016v2 and 2016v3 modeling, the quantity dropped is 5 p.c). Further more, this logic has no end level. The same observation can be created with regard to any incremental change. By way of example, really should the EPA up coming acknowledge a 1.two ppb threshold for the reason that that could only result in some smaller more loss in capture of upwind state contribution as compared to 1 ppb? If the only real foundation for moving to your one ppb threshold is that it captures a “comparable” (but in fact lesser) volume of upwind contribution, then there's no foundation for transferring to that threshold in the slightest degree. Thinking about the core statutory goal of making certain elimination of all major contribution to nonattainment or interference with servicing in the NAAQS in other states together with the broad, regional mother nature on the collective contribution trouble with regard to ozone, we continue to seek out no persuasive policy rationale to adopt a different threshold for all states of one ppb. It also is unclear why usage of a one ppb threshold could be suitable for all states underneath a far more protective NAAQS whenever a one p.c of your NAAQS contribution threshold has actually been used for a lot less protective NAAQS.
remanding the CSAPR Update on the extent that it did not demand upwind states to reduce their substantial contribution by the subsequent relevant attainment date by which downwind states ought to appear into compliance Using the NAAQS, as set up below CAA portion 181(a). See
Along with the EPA might be in violation of court docket-requested deadlines if it deferred taking final action beyond January 31, 2023, for all but two on the states coated by this action.[277] Comments asserting which the EPA need to give much more time for you to states to correct deficiencies and re-post conflict While using the managing caselaw in that they'd elevate the utmost timeframes allowable throughout the procedural framework of CAA area a hundred and ten over the attainment program of CAA section 181 which the D.C. Circuit has 88FED now held multiple situations has to be the animating target from the timing of fine neighbor obligations. The D.C. Circuit in Wisconsin
572 U.S. at 523. The EPA's Assessment of such added receptors further more is stated in Part III.C. Having said that, because we didn't suggest to apply this growth of The premise for regulation under the excellent neighbor provision receptor-identification methodology as the only real basis for locating an upwind condition connected, Within this action we have been only employing this receptor group over a confirmatory foundation. That is certainly, for states that we find connected determined by our classic modeling-centered methodology in 2023, we find In this particular closing Investigation the linkage at Stage two is strengthened and confirmed if that condition is usually linked to a number of “violating-observe” receptors.
