Comments condition that states performed their analyses depending on the flexibilities outlined in Attachment A with the March 2018 Memorandum. Reviews cite the Portion of the memorandum in which the EPA notes that “in creating their very own rules, states have adaptability to follow the common four-step transportation framework (employing [the] EPA's analytical method or somewhat various analytical ways within just these methods) or option frameworks, so long as their chosen approach has enough technical justification and is particularly in keeping with the requirements in the CAA.
“very good neighbor” necessities) to disapprove SIP submissions that fail to satisfy these specifications for that 2015 ozone NAAQS. Determined by these analyses, the EPA is disapproving SIP submittals for that 2015 ozone NAAQS for 21 states Situated throughout a wide geographic spot in eight on the 10 EPA Areas and 10 Federal judicial circuits. On condition that on its facial area this action addresses implementation of The nice neighbor needs of CAA portion 110(a)(2)(D)(i)(I) in a large number of states Found across the nation and given the interdependent nature of interstate air pollution transport plus the prevalent core of knowledge and Evaluation involved in evaluating the submitted SIPs, that is a “nationally relevant” action inside the which means of CAA section 307(b)(one). In the alternative, into the extent a court finds this motion to become locally or regionally applicable, the Administrator is training the complete discretion afforded to him beneath the CAA to make and publish a obtaining that this motion relies with a determination of “nationwide scope or effect” throughout the which means of CAA section 307(b)(1). During this ultimate action, the EPA is interpreting and applying area 110(a)(two)(D)(i)(I) of your CAA to the 2015 ozone NAAQS determined by a standard core of nationwide plan judgments and technical Assessment regarding the interstate transport of pollutants all through the continental U.
This action won't impose an details collection load underneath the provisions of the Paperwork Reduction Act. This closing motion isn't going to build any new data selection necessity other than precisely what is now essential by legislation.
checking web pages that are not projected to generally be receptors in 2023 determined by air good quality modeling) confirm the probable continuation of elevated ozone stages in 2023 at these places and make sure that almost all upwind states On this action may also be connected higher than 1 p.c with the NAAQS to one or more of such monitors. Though all this info compiled from the EPA (both of those the modeling and checking facts) plays a important function in The idea for this closing action, the EPA has also thoroughly evaluated the modeling details and various analyses and arguments offered because of the upwind states of their SIP submittals. Our evaluation with the states' analyses was generally set forth during the proposals, and the EPA During this final motion has responded to comments on our evaluation of the various info and arguments produced by states.
in the long term analytic calendar year. In case the remark's examples were being meant to reference this consideration of Federal actions in prior steps on SIP submittals, the EPA agrees that it does consider this kind of actions at these measures of its analysis, plus the EPA has continually taken this method all over its prior ozone transportation steps.
Canada and Mexico—anthropogenic emissions from People sources inside the parts of Canada and Mexico provided in the modeling area (the EPA didn't model the contributions from Canada and Mexico independently);

2016v3 Emissions Modeling TSD in Docket ID No. EPA-HQ-OAR-2021-0663. Again to Citation 28. March 2018 memorandum at 3 (“EPA also notes that, in building their own individual policies, states have adaptability to Adhere to the common four-phase transport framework (applying EPA's analytical technique or relatively diverse analytical approaches in just this measures) or option framework, so long as their picked out strategy has enough technical justification and is also according to the necessities in the CAA.”); August 2018 memorandum at 1 (“The EPA and air agencies must take into consideration if the suggestions in this assistance are suitable for Each individual circumstance.”); October 2018 memorandum at 1 (“Next the suggestions in this direction doesn't make certain that EPA will approve a SIP revision in all circumstances exactly where the recommendations are adopted, as the guidance may not utilize on the info and situation underlying a specific SIP.
The EPA disagrees. The EPA has continuously emphasized that states have the freedom Anytime to establish a revised SIP submission and submit that into the EPA for approval, and this remains true. See
Other responses take the position that states are owed a 2nd opportunity to post SIP submissions prior to the EPA usually takes closing action for many good reasons, together with statements that the EPA didn't concern sufficient advice or is or else going for walks back Formerly issued steering.
Some remarks allege the EPA is depriving States of the opportunity to goal unique emissions reductions opportunities, or the chance to revise their submissions at any place Later on. EPA Response:
A person remark states that FIPs or other Federal emissions Manage steps do not have to be included into and enforceable under point out regulation being an approvable SIP measure. They watch it as suitable for the state to depend in its SIP Submission about the emissions reductions realized by prior ozone transportation FIPs, such as the CSAPR Update or even the Revised CSAPR Update, as a permissible implies of achieving emissions reductions to do away with sizeable contribution with the 2015 ozone NAAQS. EPA Response:
The four techniques from the framework only present a reasonable organization on the Investigation of the sophisticated air high-quality problem of interstate ozone transportation. As reviewed further more in the course of this doc, the EPA has arranged its analysis of the states' SIP submissions about this analytical framework (including the particular methodologies inside of Each individual move as advanced in excess of the study course of your CSAPR rulemakings because 2011), but where states introduced choice ways either to your EPA's methodological techniques in the framework, or organized their Assessment in a few fashion that differed from it fully, We now have evaluated Those people analyses on their merits or, in some cases, discovered why even though People strategies were being satisfactory, the state nonetheless doesn't have an 88FED approvable SIP submission in general.
