87 FR 31443, 31457. The EPA evaluated California's qualitative consideration of unique topographic factors which could influence the transportation of emissions from sources inside the state to downwind receptors in Colorado and Arizona. The EPA concluded which the Point out's arguments tend not to present ample proof that identified as into concern the outcomes of your EPA's modeling. Again to Citation 337. In determining irrespective of whether to invoke the exception by producing and publishing a discovering that an motion is predicated on the determination of nationwide scope or impact, the Administrator takes into account many plan issues, like his judgment balancing the advantage of getting the D.
at 324. The court defined that “an upwind condition can `add' to downwind nonattainment regardless of whether its emissions are usually not the but-for cause.” Id.
is applicable to this motion. The Company has not imposed a prerequisite that states ought to utilize a 1 percent in the NAAQS threshold (which might reflect a transform in posture from the August 2018 memorandum). Somewhat, under the terms on the August 2018 memorandum, the Company has discovered that Alabama, Arkansas, Illinois, Indiana, Kentucky, Louisiana, Michigan, Mississippi, Missouri, Nevada, Ohio, Oklahoma, and Utah have not produced a enough showing that using an alternate contribution threshold is justified for all those States.

The EPA made use of CAMx photochemical source apportionment modeling to quantify the affect of emissions in precise upwind states on downwind nonattainment and routine maintenance receptors for eight-hour ozone.
In fact, inside the interstate transportation context, This could bring on an anomalous consequence. As an example, the D.C. Circuit turned down an argument created by Delaware from the CSAPR Update air top quality Investigation that the EPA was limited to reviewing air good quality circumstances in 2011 (rather than 2017) at some time in the statutory deadline for SIP submittals.

SIP submission deadlines, contrary to attainment deadlines, are “procedural” and for that reason not “central to your regulatory plan.” Sierra Club,
The largest contribution from Each and every point out that's the subject matter of the last motion to modeled eight-hour ozone nonattainment and modeling-dependent servicing receptors in downwind states in 2023 are furnished in Desk III.C-one of the motion. The largest contribution from Each individual condition to the additional “violating keep an eye on” maintenance-only receptors is delivered in Desk III.
Document website page views are up-to-date periodically each day and they are cumulative counts for this doc. Counts are issue to sampling, reprocessing and revision (up or down) throughout the day.
LA could use perimeter scoring and location-up taking pictures, and it could also do with far more measurement to aid Davis.
1 remark asserted that 2023 just isn't an suitable analytical calendar year due to the fact, based on the commenter, the EPA and a minimum of some downwind states have not actually executed required emissions Command demands affiliated with their nonattainment regions, and North Carolina
The EPA disagrees with each allegations. Within this respect, it is important to assessment the recent background on the EPA's regulatory steps and litigation with respect to very good neighbor obligations for both equally the 2008 and 2015 ozone NAAQS, and specifically, the significant supplemental workload the Agency took on while in the wake of the remand on the CSAPR Update in Wisconsin.
