 Summary

Appendix A New York PM2.5 Control Measures  

	I. Introduction

     The Environmental Protection Agency (EPA) is reviewing elements of the State Implementation Plan (SIP) submission from New York regarding the infrastructure requirements of section 110 of the Clean Air Act (CAA) for the 2012 annual fine particulate matter (PM2.5) NAAQS.
This Technical Support Document addresses CAA section 110(a)(2)(D)(i)(I), or the "good neighbor" provision of the Clean Air Act (CAA).

II. Background

Fine Particulate Matter

     On December 14, 2012 (78 FR 3086), the EPA promulgated a revised primary NAAQS for fine particulate matter (PM2.5) for the annual standard. The revised standard was set at the level of 12 micrograms per cubic meter (ug/m[3]) calculated as an annual average, which is averaged over a three-year period. Infrastructure SIPs for the 2012 PM2.5 NAAQS were due by December 14, 2015.       
PM2.5 can be formed either directly, from construction sites, unpaved roads, fields, or point source stacks, or indirectly as a result of complex reactions within the atmosphere of chemicals such as sulfur dioxide (SO2) and oxides of nitrogen (NOx), both of which are the main precursors for the formation of PM2.5. Both SO2 and NOx are emitted mainly from point sources, but can also be emitted from nonpoint, onroad, and nonroad sources.

Infrastructure and Transport

Under CAA sections 110(a)(1) and 110(a)(2), each state is required to submit a SIP that provides for the implementation, maintenance and enforcement of each primary or secondary NAAQS. Section 110(a)(1) requires each state to make this SIP submission within 3 years after promulgation of a new or revised NAAQS. This type of SIP submission is commonly referred to as an " infrastructure SIP." Section 110(a)(2) includes a list of specific elements that each such plan submission must meet. The conceptual purpose of an infrastructure SIP submission is to assure that the state' s SIP contains the necessary structural requirements for the implementation of the new or revised NAAQS, whether by demonstrating that the state's SIP already contains or sufficiently addresses the necessary provisions, or by making a substantive SIP revision to update the plan provisions.
One of the infrastructure requirements, section 110(a)(2)(D)(i)(I) of the CAA requires states to address the interstate transport of air pollution that affects downwind states' ability to attain and maintain the NAAQS. Specifically, section 110(a)(2)(D)(i)(I) of the CAA requires state SIPs to address emissions activity in one state that contributes significantly to nonattainment, or interferes with maintenance, of the NAAQS in any downwind state. The EPA sometimes refers to these requirements as prong 1 (significant contribution to nonattainment) and prong 2 (interference with maintenance), or jointly the "good neighbor" provision of the CAA.  
The EPA has addressed the interstate transport requirements of CAA section 110(a)(2)(D)(i)(I) with respect to PM2.5 in several past regulatory actions. In 2011 we promulgated the Cross-State Air Pollution Rule (CSAPR, 76 FR 48208, August 8, 2011) in order to address the obligations of states  -  and of the EPA when states have not met their obligations  -  under CAA section 110(a)(2)(D)(i)(I) to prohibit air pollution contributing significantly to nonattainment in, or interfering with maintenance by, any other state with regard to several NAAQS, including the 1997 annual and 2006 24-hour PM2.5 NAAQS. 
On March 17, 2016, the EPA issued a memorandum providing information on the development and review of SIPs that address CAA section 110(a)(2)(D)(i)(I) for the 2012 PM2.5  NAAQS (2016 guidance memorandum). 

  
III. New York's Submittal

On November 30, 2016, New York submitted a revision to its SIP to satisfy the infrastructure requirements of section 110(a)(2) of the CAA for the 2012 PM2.5 annual standard, including the interstate transport requirements of section 110(a)(2)(D)(i)(I). 
The portion of New York's November 30, 2016 SIP submittal addressing interstate transport indicates how New York considers CAA 110(a)(2)(D)(i)(I) to be adequately addressed based on the State's contribution analysis to determine whether emissions from New York State contribute significantly to nonattainment or interference with maintenance in another state. 
In their analysis New York considered the areas that were designated as nonattainment for the 2012 PM2.5 NAAQS (i.e., California, Idaho, Ohio, and Pennsylvania), and violating air monitors in states (i.e., in Cuyahoga County, Ohio and Allegheny County, Pennsylvania) that New York was linked to as significantly contributing to nonattainment or interference with maintenance by the 2012 EPA modeling performed for CSAPR. New York performed Community Multiscale Air
(CMAQ) Modeling to determine projected annual PM2.5 Design Values for year 2018, which included the violating monitors in both Allegheny County and Cuyahoga County. Based on New York's modeling, which did not show violations of the NAAQS at either location in 2018, New York concluded that the "Good Neighbor" provision of the CAA was adequately addressed. 
The EPA notes that New York provided the results of their CMAQ modeling only and did not include information necessary for the EPA to fully evaluate New York's modeling. New York did not provide a description of the methodology used for the 2018 projection or provide a description how the State's modeling assessed interference with maintenance. The submission also did not include model input and output data, including emissions and meteorological data used, and other relevant information to determine the adequacy of New York's modeling analysis.
Since New York's November 30, 2016 SIP submission, actual 2018 annual PM2.5 Design Values shows that that there are no longer violating monitors in Cuyahoga County, Ohio, but that monitors  in Allegheny County, Pennsylvania continue to show violations.
In their submission, New York noted that in both the State of Pennsylvania's recommendation to the EPA for the 2012 PM2.5 NAAQS, and the EPA's Technical Support Document (TSD) for the 2012 PM2.5 NAAQS designations, PM2.5 exceedances in Allegheny County were identified as a local issue and were not linked to out of state emissions from New York. The EPA specifically limited the nonattainment area to Allegheny County only, even though an adjacent county (Cambria County) also contained a violating monitor at the time of the designation. 
New York's submittal also described existing PM2.5 control measures, including SIP approved measures, that apply to PM2.5 sources located within New York State. These measures are listed in Appendix A (New York PM2.5 Control Measures) of this TSD.

IV.	Evaluation of New York's Submittal

Section 110(a)(2)(D)(i) requires SIPs to include adequate provisions prohibiting any source or other type of emissions activity in one state that will (I) contribute significantly to nonattainment, or interfere with maintenance of the NAAQS in another state, or (II) interfere with measures required to prevent significant deterioration of air quality, or to protect visibility in another state. 
As previously mentioned, the EPA issued the 2016 guidance memorandum that the states should follow as they prepare their "good neighbor" SIPs. The 2016 guidance memorandum outlined the four step framework the EPA has historically used to evaluate interstate transport for regional pollutants like ozone and fine particulate matter under section 110(a)(2)(D)(i)(I), including the EPA's CSAPR. In this proposed rulemaking, we are following that framework, which is as follows:

 Identification of potential downwind nonattainment and maintenance receptors;
        Identification of upwind states contributing to downwind nonattainment and maintenance receptors;
        For states identified as contributing to downwind air quality problem, identification of upwind emissions reductions necessary to prevent upwind states from significantly contributing to nonattainment or interfering with maintenance of receptors; and
 For states that are found to have emissions that significantly contribute to non-attainment or interfere with maintenance downwind, reducing the identified upwind emissions through adoption of permanent and enforceable measures.

The 2016 guidance memorandum included modeling data for the years 2017 and 2025 and
evaluated projected air quality relative to the 2012 annual PM2.5 NAAQS. For purposes of evaluating interstate transport it is appropriate to consider a projected air quality in a future year aligned with the relevant attainment deadlines, which for 2012 annual PM2.5 NAAQS would be 2021 for nonattainment areas classified as Moderate. Since modeling results are only available for 2017 and 2025, the 2016 guidance memorandum explains that one way to assess potential receptors for 2021 is to assume that receptors projected to have average and/or maximum design values above the NAAQS in both 2017 and 2025 are also likely to be either "nonattainment" or "maintenance" receptors in 2021. Similarly, it may be reasonable to assume that receptors that are projected to attain the NAAQS in both 2017 and 2025 are also likely to be "attainment" receptors in 2021. Where a potential receptor is projected to be " nonattainment" or " maintenance" in 2017, but projected to be "attainment " in 2025, further analysis of the emissions and modeling may be
needed to make a further judgement regarding the receptor status in 2021.
In CSAPR, the EPA defined "nonattainment" receptors as those monitoring sites that are projected to exceed the NAAQS in the appropriate future analytic year, while "maintenance" receptors are monitoring sites that are projected to have difficulty maintaining the relevant NAAQS in a scenario that takes into account historical variability in air quality at that receptor (81 FR 74504,74531, October 26, 2016). Accordingly, the EPA used the average projected design value to identify potential " nonattainment" receptors, while the maximum projected design value was used to identify potential "maintenance" receptors. Based on this approach, the potential receptors are outlined in Table 1 in the 2016 guidance memorandum. Most of the potential receptors are in California, located in the San Joaquin Valley or South Coast nonattainment areas; however, there is also one potential receptor in Shoshone County, Idaho, and one potential receptor in Allegheny County, Pennsylvania.
The 2016 guidance memorandum noted that because of data quality problems nonattainment and maintenance projections were not done for all or portions of Florida, Illinois, Idaho, Tennessee and Kentucky. As of November 2019, data quality problems have since been resolved based on the latest air quality data for Florida, Illinois, Idaho, Tennessee and Kentucky, with those areas having design values below the 2012 PM2.5 NAAQS and expected to maintain the NAAQS due to downward emission trends for NOx and SO2. 
Therefore, from "Step 1" of this evaluation, the areas identified as "potential downwind nonattainment and maintenance receptors" are:
 Seventeen potential receptors in California, located in the San Joaquin Valley or South Coast nonattainment areas;
 One receptor in Shoshone County, Idaho;
 One receptor in Allegheny County, Pennsylvania

As stated above, "Step 2" is the identification of states contributing to downwind nonattainment and maintenance receptors, such that further analysis is required to identify necessary upwind reductions. For this step, we will be specifically determining if New York emissions contribute to downwind nonattainment and maintenance receptors.
For the 1997 and 2006 PM2.5 NAAQS we have used air quality modeling and an air quality threshold of one percent of the PM2.5 NAAQS to link contributing states to projected nonattainment or maintenance receptors (76 FR 48237, August 8, 2011). That is, if an upwind state contributes less than the one percent threshold to a downwind nonattainment or maintenance receptor, we determine that the state is not "linked" and therefore does not significantly contribute to nonattainment at the receptor. We have not set an air quality threshold for the 2012 annual PM2.5 NAAQS and we do not have air quality modeling showing contributions to projected nonattainment or maintenance receptors for this NAAQS.
The EPA believes that a proper and well-supported weight of evidence approach can provide sufficient information for purposes of addressing transport with respect to the 2012 annual PM2.5 NAAQS. We rely on the CSAPR air quality modeling conducted for purposes of evaluating upwind state impacts on downwind air quality with respect to the 1997 annual PM2.5 NAAQS of 15 ug/m[3] (as well as the 2006 24-hour PM2.5 NAAQS, and 1997 Ozone NAAQS). Although not conducted for purposes of evaluating the 2012 annual PM2.5 NAAQS, this modeling can inform our analysis regarding both the general magnitude of downwind PM2.5 impacts and the downwind distance in which states may contribute to receptors with respect to the 2012 annual PM2.5 NAAQS of 12 ug/m[3]. In particular, if the same 1% contribution threshold used in CSPAR for the 1997 and 2006 PM2.5 NAAQS applied to the 2012 PM2.5 NAAQS, we could consider the fact that a particular state's impact was below that value (that is, 0.12 ug/m[3]).We also note that New York's submittal, described above, relies on several factors to support a finding that emissions from New York sources do not significantly contribute to nonattainment, or interfere with maintenance of, the 2012 PM2.5 NAAQS in downwind states. 
We note that no single piece of information is by itself dipositive of the issue. Instead, the total weight of all the evidence taken together is used to evaluate significant contributions to nonattainment or interference with maintenance of the 2012 PM2.5 NAAQS in another state.
Each of the potential receptors is discussed below. For additional information, links to the documents relied upon for this analysis can be found throughout the document and the documents can be found in the docket for this action.

California 

The EPA's analysis shows that New York's PM2.5 emissions and/or PM2.5 precursors do not contribute to the California potential receptors identified in the 2006 Memorandum. New York is more than 1,900 miles to the east (from each states' respective closest points), and downwind of California nonattainment and maintenance receptors. 
Furthermore, most emissions impacting PM2.5 levels in California are directly emitted PM2.5 and/or PM2.5 precursors from within the state based on the EPA's analysis performed for the 2012 PM2.5 Designations. Although air quality designations are not relevant to our evaluation of interstate transport; the analysis developed for the 2012 annual PM2.5 NAAQS designations process provides an in-depth evaluation of factors critical in evaluating transport of PM2.5 and PM2.5 precursors, including evaluation of local emissions, wind speed and direction, topographical and meteorological conditions and seasonal variations recorded at the monitors, which all support the conclusion that New York's emissions of PM2.5 and its precursors do not contribute to the California receptors. The TSD for the California analysis for the 2012 PM2.5 NAAQS designation is included in the docket.
For these reasons, it is unlikely that New York will significantly contribute to nonattainment or interfere with maintenance of the 2012 PM2.5 NAAQS in California. Accordingly, the EPA proposes to find that New York will not significantly contribute to nonattainment or interfere with maintenance of the 2012 PM2.5 NAAQS in California.

Idaho

The EPA's analysis shows that New York's PM2.5 emissions and/or PM2.5 precursors do not contribute to the Idaho potential receptor identified in the 2016 guidance memorandum. New York is more than 1,500 miles to the east (from each states' respective closest points) and downwind of the Idaho receptor. 
The EPA has found that the majority of the emissions impacting PM2.5 levels in Idaho, came during the winter months and could be attributed to residential wood combustion. The EPA notes that air quality designations are not relevant to our evaluation of interstate transport; however, the analysis developed for the 2012 annual PM2.5 NAAQS designations process provide an in depth evaluation of factors critical in evaluating transport of PM2.5 and PM2.5 precursors, including evaluation of local emissions, wind speed and direction, topographical and meteorological conditions and seasonal variations recorded at the monitor, which all support the conclusion that New York's emissions of PM2.5 and its precursors will not contribute to nonattainment maintenance concerns at the Idaho potential receptor. The TSD for the Idaho analysis for the 2012 PM2.5 NAAQS designation is included in the docket.
The EPA notes that although Shoshone County, Idaho was identified as a potential maintenance receptor based on the EPA modeling, the Idaho receptor has shown little difficulty in maintaining the NAAQS based on recent design values at the Shoshone County monitor, which show a clear downward trend. Air quality design values have decreased from 11.9 ug/m[3] (2014-2016 Design Value) to 11.2 ug/m[3](2016-2018 Design Value). The EPA finalized a Clean Data Determination (CDD) for the West Silver Valley, Idaho nonattainment area in December 2018 (83 FR 65535, December 21, 2018).
For these reasons, it is unlikely that New York will significantly contribute to nonattainment or interfere with maintenance of the 2012 PM2.5 NAAQS in Idaho. Accordingly, the EPA proposes to find that New York will not significantly contribute to nonattainment or interfere with maintenance of the 2012 PM2.5 NAAQS in Idaho.  

Allegheny County, Pennsylvania

The EPA's CSAPR air quality modeling shows that New York's PM2.5 emissions and/or PM2.5 precursors would contribute to a potential receptor (i.e., Liberty monitor) in Allegheny County, Pennsylvania identified in the 2016 guidance memorandum. However, the EPA believes that Allegheny County will meet the NAAQS by 2021 with no additional controls needed from New York. The EPA has found that there were strong local influences throughout Allegheny County and contributions from nearby states that contributed to its nonattainment. In recent years, local contributors to the Liberty monitor have taken steps to improve air quality which will likely bring the monitor into compliance with the 2012 PM2.5 annual NAAQS by the 2021 attainment date. 
As previously mentioned, the EPA conducted CSAPR air quality modeling in order to project impacts from upwind states on downwind monitors with respect to the 1997 annual PM2.5 NAAQS of 15 ug/m3 . In that modeling, the EPA determined that emissions from several other states were linked to projected nonattainment in Allegheny County, Pennsylvania. The impact of New York emissions was also analyzed in that modeling, and the impact from New York emissions at the Liberty monitor was 0.172 ug/m[3]. This level of impact is greater than 1% of the 2012 annual PM2.5 NAAQS (0.12 ug/m[3]), and although, as noted above, the EPA has not set a contribution threshold for that NAAQS, the EPA did set a contribution of 1% for the 1997 and 2006 PM2.5 NAAQS and considers that percentage amount to be informative as weight of evidence in determining whether an area significantly contributes to downwind nonattainment or maintenance receptors.
However, substantial evidence indicates that Allegheny County should not be considered a downwind attainment or maintenance receptor. While the 2016-2018 PM2.5 design value for Allegheny County is still slightly above the 2012 PM2.5 NAAQS as shown below in Table 1, the EPA believes that Allegheny County will attain and maintain the NAAQS by 2021 with no need for further emissions controls, beyond what is already "on-the-books" in both Pennsylvania and in upwind states, including New York. The EPA reaches this conclusion based on the trend of declining PM2.5 design values, analysis of the EPA's prior PM2.5 air quality modeling results, recent and planned emissions reductions in upwind states, and measures Pennsylvania is currently developing to address PM2.5 sources in order to meet the 2012 PM2.5 NAAQS.
The modeling information contained in the EPA's 2016 PM2.5 Memorandum shows that the Liberty monitor may have a maintenance issue in 2017 but is projected to both attain and maintain the NAAQS by 2025. A linear interpolation of the modeled design values to 2021 shows that the monitor is likely to both attain and maintain the standard by 2021. A simple linear interpolation of the modeled design values to 2021 for the Liberty monitor leads to a projected 2021 average design value of 11.42 ug/m[3]  and a maximum design value of 11.91  ug/m[3] , which are both below the 2012 PM2.5 NAAQS.
Emissions and air quality data trends help to corroborate this conclusion. Since 2008, local and regional emissions reductions of primary PM2.5, SO2, and NOx, have led to large reductions in annual PM2.5 design values in Allegheny County. In 2008, most of Allegheny County's PM2.5 monitors exceeded the level of the 2012 NAAQS (the 2008-2010 annual average design values ranged from 10.1-16.3 ug/m[3], as shown in Table 1). The 2016-2018 annual average PM2.5 design values now show that only one monitor (Liberty, at 12.6 ug/m[3]) exceeds the health-based annual PM2.5 NAAQS of 12.0 ug/m[3].

* In this table, all design values are calculated based on the rules specified in Appendix N for the 2012 PM2.5 NAAQS. The * denotes design values that are not valid in accordance with the 2012 NAAQS.

The Liberty monitor (ID 420030064) is already close to attaining the NAAQS, and further emissions reductions planned over the next several  years will lead to additional reductions in measured PM2.5 concentrations. There are both local and regional components to the measured PM2.5 levels in Allegheny County. Previous CSAPR modeling showed that regional emissions from upwind states, particularly SO2 and NOx emissions, contribute to PM2.5 nonattainment at the Liberty monitor. In recent years, large SO2 and NOx reductions from power plants have occurred in Pennsylvania and states upwind from the Greater Pittsburgh region. This is due to both installation of emissions controls and retirements of electric generating units (EGUs). Projected power plant closures and additional emissions controls in Pennsylvania and upwind states will help further reduce direct PM2.5 emissions along with PM2.5 precursor SO2 and NOx emissions. Regional emission reductions will continue to occur  from current on-the-books federal and state regulations such as the federal on-road and non-road vehicle programs and various rules for major stationary emissions sources.
In addition to regional emissions reductions and plant closures, additional local reductions to both direct PM2.5 and SO2 emissions are also expected to occur and should also contribute to further declines in Allegheny County's PM2.5 monitor concentrations. For example, significant SO2 reductions have recently occurred at US Steel's integrated steel mill facilities in southern Allegheny County as part of a 1-hr SO2 NAAQS SIP. Reductions are largely due to declining sulfur content in the Clairton Coke Work's coke oven gas (COG). Because this COG is burned at US Steel's Clairton Coke Works, Irvin Mill, and Edgar Thompson Steel Mill, these reductions in sulfur content should contribute to much lower PM2.5 precursor emissions in the immediate future. The Allegheny SO2 SIP submission, which the EPA is reviewing pursuant to CAA requirements, also discusses expected lower SO2 emissions in the Allegheny County area resulting from reduced sulfur content requirements in vehicle fuels, reductions in general emissions due to declining population in the Greater Pittsburgh region, and several shutdowns of significant emitters of SO2 in Allegheny County.
The analysis of the EPA modeling projection results, the recent downward trend in local and upwind emissions reductions, the expected continued downward trend in emissions between 2017 and 2021, and the downward trend in monitored PM2.5 concentrations all indicate that the Liberty monitor will attain and be able to maintain the 2012 annual PM2.5 NAAQS by the 2021 attainment deadline. Not only have emissions trended downward in Allegheny County, because of reductions from CSAPR implementation across the CSAPR states, ambient concentrations of PM2.5 have trended downward nearly universally among PM air quality monitors nationwide. 
Accordingly, while the CSAPR modeling analysis shows that New York does contribute more than 1% of the 2012 PM2.5 NAAQS, the EPA finds that Allegheny County is unlikely to have either nonattainment or maintenance problems in 2021 and is therefore unlikely to be a receptor for purposes of interstate transport. For these reasons, the EPA proposes to find that New York  emissions will not significantly contribute to nonattainment or interfere with maintenance of the 2012 PM25 NAAQS for Allegheny County, Pennsylvania.

V. Summary

The EPA is proposing that New York has addressed the interstate transport provisions for the 2012 PM2.5 NAAQS under 110(a)(2)(d)(i)(I). The EPA has identified potential nonattainment or maintenance receptors in California, Idaho, and Pennsylvania, and has determined that New York emissions do not contribute significantly to nonattainment of or interfere with maintenance of the 2012 PM2.5 NAAQS. 
 For potential receptors in California, and Idaho, the EPA believes that the large distance between New York and the potential receptors, as well as supporting information from the 2012 Designations, provides sufficient reason why New York emissions do not contribute significantly to nonattainment of or interfere with maintenance of the 2012 PM2.5 NAAQS . 
For the potential receptor in Allegheny County, Pennsylvania, the EPA believes that emission and ambient air quality data trends as well as the EPA interpolation of the modeled design values provide sufficient reason that Allegheny County is unlikely to have either nonattainment or maintenance problems in 2021. Therefore, New York emissions do not significantly contribute to nonattainment or interfere with maintenance of the 2012 PM2.5 NAAQS in Allegany County, Pennsylvania.
Since we propose to determine that New York will not contribute significantly to nonattainment of or interfere with maintenance of the 2012 PM2.5 NAAQS, in another state, steps 3 and 4 of this evaluation are not necessary. Nonetheless, the EPA notes that New York has numerous control measures in place that will help ensure that New York will continue to limit emissions in the state (see Appendix A).
