SUPPLEMENTARY INFORMATION:

On February 27, 2020, DEP submitted a revision to the Pennsylvania SIP to incorporate a plan for maintaining the 1997 ozone NAAQS through July 25, 2027 in accordance with CAA section 175A. The submittal is titled, “State Implementation Plan Revision: Second Maintenance Plan for the Harrisburg-Lebanon-Carlisle 1997 8-Hour Ozone Nonattainment Area,” which will be referred to as the “Harrisburg-Lebanon-Carlisle Area second maintenance plan” throughout this document.

I. Background

In 1979, under section 109 of the CAA, EPA established primary and secondary NAAQS for ozone at 0.12 parts per million (ppm), averaged over Start Printed Page 54955a 1-hour period. 44 FR 8202 (February 8, 1979). On July 18, 1997 (62 FR 38856).[1] EPA revised the primary and secondary NAAQS for ozone to set the acceptable level of ozone in the ambient air at 0.08 ppm, averaged over an 8-hour period. EPA set the 1997 ozone NAAQS based on scientific evidence demonstrating that ozone causes adverse health effects at lower concentrations and over longer periods of time than was understood when the pre-existing 1-hour ozone NAAQS was set.

Following promulgation of a new or revised NAAQS, EPA is required by the CAA to designate areas throughout the nation as attaining or not attaining the NAAQS. On June 15, 2004 (69 FR 23858), EPA designated the Harrisburg-Lebanon-Carlisle Area as a nonattainment area for the 1997 ozone NAAQS. The area, consisting of Cumberland, Dauphin, Lebanon and Perry Counties, was redesignated to attainment on July 25, 2007 (72 FR 40749), and effective the same day.

Once a nonattainment area has three years of complete and certified air quality data that has been determined to attain the NAAQS, and the area has met the other criteria outlined in CAA section 107(d)(3)(E),[2] the state can submit a request to EPA to redesignate the area to attainment. Areas that have been redesignated by EPA from nonattainment to attainment are referred to as “maintenance areas.” One of the criteria for redesignation is to have an approved maintenance plan, under CAA section 175A. The maintenance plan must demonstrate that the area will continue to maintain the standard for the period extending 10 years after redesignation, and it must contain such additional measures as necessary to ensure maintenance as well as contingency measures as necessary to assure that violations of the standard will be promptly corrected.

On July 25, 2007 (72 FR 40749 effective July 25, 2007), EPA approved a redesignation request (and maintenance plan) from DEP for the Harrisburg-Lebanon-Carlisle area. In accordance with section 175A(b), at the end of the eighth year after the effective date of the redesignation, the state must also submit a second maintenance plan to ensure ongoing maintenance of the standard for an additional 10 years.

EPA's final implementation rule for the 2008 ozone NAAQS revoked the 1997 ozone NAAQS and provided that one consequence of revocation was that areas that had been redesignated to attainment (i.e., maintenance areas) for the 1997 ozone NAAQS no longer needed to submit second 10-year maintenance plans under CAA section 175A(b).[3] However, in South Coast Air Quality Management District v. EPA[4] (South Coast II), the United States Court of Appeals for the District of Columbia (D.C. Circuit) vacated EPA's interpretation that, because of the revocation of the 1997 ozone standard, second maintenance plans were not required for “orphan maintenance areas,” (i.e. the Harrisburg-Lebanon-Carlisle area) that had been redesignated to attainment for the 1997 ozone NAAQS and were designated attainment for the 2008 ozone NAAQS. Thus, states with these “orphan maintenance areas” under the 1997 ozone NAAQS must submit maintenance plans for the second maintenance period.

As previously discussed, CAA section 175A sets forth the criteria for adequate maintenance plans. In addition, EPA has published longstanding guidance that provides further insight on the content of an approvable maintenance plan, explaining that a maintenance plan should address five elements: (1) An attainment emissions inventory; (2) a maintenance demonstration; (3) a commitment for continued air quality monitoring; (4) a process for verification of continued attainment; and (5) a contingency plan. The 1992 Calcagni Memo [5] provides that states may generally demonstrate maintenance by either performing air quality modeling to show that the future mix of sources and emission rates will not cause a violation of the NAAQS or by showing that future emissions of a pollutant and its precursors will not exceed the level of emissions during a year when the area was attaining the NAAQS (i.e., attainment year inventory). See 1992 Calcagni Memo at p. 9. EPA further clarified in three subsequent guidance memos describing “limited maintenance plans” (LMPs) [6] that the requirements of CAA section 175A could be met by demonstrating that the area's design value [7] was well below the NAAQS and that the historical stability of the area's air quality levels showed that the area was unlikely to violate the NAAQS in the future. Specifically, EPA believes that if the most recent air quality design value for the area is at a level that is below 85% of the standard, or in this case below 0.071 ppm, then EPA considers the state to have met the section 175A requirement for a demonstration that the area will maintain the NAAQS for the requisite period. Accordingly, on February 27, 2020, DEP submitted the Harrisburg-Lebanon-Carlisle Area second maintenance plan, following the LMP guidance, and demonstrating that the area will maintain the 1997 ozone NAAQS through July 25, 2027, i.e., through the entire 20-year maintenance period.

II. Summary of SIP Revision and EPA Analysis

DEP's February 27, 2020 SIP submittal outlines a plan for continued maintenance of the 1997 ozone NAAQS which addresses the criteria set forth in the 1992 Calcagni Memo as follows.

A. Attainment Emissions Inventory

For maintenance plans, a state should develop a comprehensive and accurate inventory of actual emissions for an attainment year which identifies the level of emissions in the area which is sufficient to maintain the NAAQS. The inventory should be developed consistent with EPA's most recent guidance. For ozone, the inventory should be based on typical summer day's emissions of oxides of nitrogen (NOX) and volatile organic compounds (VOC), the precursors to ozone formation. In the first maintenance plan for the Harrisburg-Lebanon-Carlisle Area, DEP used 2004 for the attainment year inventory, because 2004 was one of the years in the 2003-2005 three-year period when the area first attained the Start Printed Page 549561997 ozone NAAQS.[8] The Harrisburg-Lebanon-Carlisle Area continued to monitor attainment of the 1997 ozone NAAQS in 2014. Therefore, the emissions inventory from 2014 represents emissions levels conducive to continued attainment (i.e., maintenance) of the NAAQS. Thus, DEP is using 2014 as representing attainment level emissions for its second maintenance plan. Pennsylvania used 2014 summer day emissions from EPA's 2014 version 7.0 modeling platform as the basis for the 2014 inventory presented in Table 1.[9]

The data shown in Table 1 is based on the 2014 National Emissions Inventory (NEI) version 2.[10] The inventory addresses four anthropogenic emission source categories: Stationary (point) sources, stationary nonpoint (area) sources, nonroad mobile, and onroad mobile sources. Point sources are stationary sources that have the potential to emit (PTE) more than 100 tons per year (tpy) of VOC, or more than 50 tpy of NOX, and which are required to obtain an operating permit. Data are collected for each source at a facility and reported to DEP. Examples of point sources include kraft mills, electrical generating units (EGUs), and pharmaceutical factories. Nonpoint sources include emissions from equipment, operations, and activities that are numerous and in total have significant emissions. Examples include emissions from commercial and consumer products, portable fuel containers, home heating, repair and refinishing operations, and crematories. The onroad emissions sector includes emissions from engines used primarily to propel equipment on highways and other roads, including passenger vehicles, motorcycles, and heavy-duty diesel trucks. The nonroad emissions sector includes emissions from engines that are not primarily used to propel transportation equipment, such as generators, forklifts, and marine pleasure craft.

EPA reviewed the emissions inventory submitted by DEP and proposes to conclude that the plan's inventory is acceptable for the purposes of a subsequent maintenance plan under CAA section 175A(b).

B. Maintenance Demonstration

In order to attain the 1997 ozone NAAQS, the three-year average of the fourth-highest daily average ozone concentrations (design value, or “DV”) at each monitor within an area must not exceed 0.08 ppm. Based on the rounding convention described in 40 CFR part 50, appendix I, the standard is attained if the DV is 0.084 ppm or below. CAA section 175A requires a demonstration that the area will continue to maintain the NAAQS throughout the duration of the requisite maintenance period. Consistent with the prior guidance documents discussed previously in this document as well as EPA's November 20, 2018 “Resource Document for 1997 Ozone NAAQS Areas: Supporting Information for States Developing Maintenance Plans” (2018 Resource Document),[11] EPA believes that if the most recent DV for the area is well below the NAAQS (e.g. below 85%, or in this case below 0.071 ppm), the section 175A demonstration requirement has been met, provided that Prevention of Significant Deterioration (PSD) requirements, any control measures already in the SIP, and any Federal measures remain in place through the end of the second 10-year maintenance period (absent a showing consistent with section 110(l) that such measures are not necessary to assure maintenance).

For the purposes of demonstrating continued maintenance with the 1997 ozone NAAQS, DEP provided 3-year DVs at monitors located in the Harrisburg-Lebanon-Carlisle Area from 2009 to 2019. This includes DVs at monitors for 2009-2011, 2010-2012, 2011-2013, 2012-2014, 2013-2015, 2014-2016, 2015-2017, and 2016-2018, which are shown in Table 2.[12] In Start Printed Page 54957addition, EPA has reviewed the most recent ambient air quality monitoring data for ozone in the Harrisburg-Lebanon-Carlisle Area, as submitted by Pennsylvania and recorded in EPA's Air Quality System (AQS). The most recent DV (i.e. 2017-2019) at monitors located in the Harrisburg-Lebanon-Carlisle Area are also shown in Table 2.[13] There are three monitoring sites in the Harrisburg-Lebanon-Carlisle area, two in Dauphin County and one in Lebanon County. Please note that there was a monitor in Perry County (monitor 42-099-0301), but it was discontinued on October 31, 2014. As can be seen in Table 2, DVs at all monitors located in the Harrisburg-Lebanon-Carlisle Area have been well below 85% of the 1997 ozone NAAQS (i.e. 0.071 ppm) since the 2014-2016 period. The highest DV for the 2017-2019 period at a monitor in the Harrisburg-Lebanon-Carlisle Area is 0.066 ppm, which is well below 85% of the 1997 NAAQS.

* Monitor 42-043-0401 was shut down in January 2012 and moved to a new site.

Additionally, states can support the demonstration of continued maintenance by showing stable or improving air quality trends. According to EPA's 2018 Resource Document, several kinds of analyses can be performed by states wishing to make such a showing. One approach is to take the highest, most recent DV at a monitor located in the area and add the maximum design value increase (over one or more consecutive years) that has been observed in the area over the past several years. A sum that does not exceed the level of the 1997 ozone NAAQS may be a good indicator of expected continued attainment. As shown in Table 2, the largest increase in DVs at a monitor located in the Harrisburg-Lebanon-Carlisle Area was 0.004 ppm, which occurred between the 2009-2011 (0.073 ppm) and the 2010-2012 (0.077 ppm) DVs at the monitor located in Dauphin County (AQS ID 42-043-1100). Adding 4 ppb to the highest DV for the 2017-2019 period (0.066 ppm) results in 0.070 ppm, a sum that is still below the 1997 ozone NAAQS.

The Harrisburg-Lebanon-Carlisle Area has maintained air quality levels well below the 1997 ozone NAAQS since the Area first attained the NAAQS in 2005.[14] Additional supporting information that the area is expected to continue to maintain the standard can be found in projections of future year DVs that EPA recently completed to assist states with development of interstate transport SIPs for the 2015 8-hour ozone NAAQS. Those projections, made for the year 2023, show that the highest DV at a monitor located in the Harrisburg-Lebanon-Carlisle Area is expected to be 0.0586 ppm.[15] Therefore, EPA proposes to determine that future violations of the 1997 ozone NAAQS in the Harrisburg-Lebanon-Carlisle Area are unlikely.

C. Continued Air Quality Monitoring and Verification of Continued Attainment

Once an area has been redesignated to attainment, the state remains obligated to maintain an air quality network in accordance with 40 CFR part 58, in order to verify the area's attainment status. In the February 27, 2020 submittal, DEP commits to continue to operate their air monitoring network in accordance with 40 CFR part 58. DEP also commits to track the attainment status of the Harrisburg-Lebanon-Carlisle Area for the 1997 ozone NAAQS through the review of air quality and emissions data during the second maintenance period. This includes an annual evaluation of vehicles miles traveled (VMT) and stationary source emissions data compared to the assumptions included in the LMP. DEP also states that it will also evaluate the periodic (i.e., every three years) emission inventories prepared under EPA's Air Emission Reporting Requirements (40 CFR part 51, subpart A). Based on these evaluations, DEP will consider whether any further emission control measures should be implemented for the Harrisburg-Lebanon-Carlisle County Area. EPA has analyzed the commitments in DEP's submittal and is proposing to determine that they meet the requirements for continued air quality monitoring and verification of continued attainment.

D. Contingency Plan

The contingency plan provisions are designed to promptly correct or prevent a violation of the NAAQS that might occur after redesignation of an area to attainment. Section 175A of the CAA requires that a maintenance plan include such contingency measures as EPA deems necessary to assure that the state will promptly correct a violation of the NAAQS that occurs after redesignation. The maintenance plan should identify the contingency measures to be adopted, a schedule and procedure for adoption and implementation of the contingency measures, and a time limit for action by the state. The state should also identify specific indicators to be used to determine when the contingency measures need to be adopted and implemented. The maintenance plan must require that the state will implement all pollution control measures that were contained in the SIP before redesignation of the area to attainment. See section 175(A)(d) of the CAA.

DEP's February 27, 2020 submittal includes a contingency plan for the Harrisburg-Lebanon-Carlisle Area. In the event that the fourth highest eight-hour ozone concentrations at a monitor in the Harrisburg-Lebanon-Carlisle Area exceeds 84 ppb (equivalent to 0.084 ppm) for two consecutive years, but prior to an actual violation of the NAAQS, DEP will evaluate whether Start Printed Page 54958additional local emission control measures should be implemented that may prevent a violation of the NAAQS.[16] After analyzing the conditions causing the excessive ozone levels, evaluating the effectiveness of potential corrective measures, and considering the potential effects of federal, state, and local measures that have been adopted but not yet implemented, DEP will begin the process of implementing selected measures so that they can be implemented as expeditiously as practicable following a violation of the NAAQS. In the event of a violation, DEP commits to adopting additional emission reduction measures as expeditiously as practicable in accordance with the schedule included in the contingency plan as well as the CAA and applicable Pennsylvania statutory requirements.

DEP will use the following criteria when considering additional emission reduction measures to adopt to address a violation of the 1997 ozone NAAQS in the Harrisburg-Lebanon-Carlisle Area: (1) Air quality analysis indicating the nature of the violation, including the cause, location, and source; (2) emission reduction potential, including extent to which emission generating sources occur in the nonattainment area; (3) timeliness of implementation in terms of the potential to return the area to attainment as expeditiously as practicable; and (4) costs, equity, and cost-effectiveness. The measures DEP would consider pursuing for adoption in the Harrisburg-Lebanon-Carlisle Area include, but are not limited to, those summarized in Table 3. If additional emission reductions are necessary, DEP commits to adopt additional emission reduction measures to attain and maintain the 1997 ozone NAAQS.

Table 3—Harrisburg-Lebanon-Carlisle Area Second Maintenance Plan Contingency Measures

Non-Regulatory Measures:
Voluntary diesel engine “chip reflash” (installation software to correct the defeat device option on certain heavy-duty diesel engines)

EPA proposes to find that the contingency plan included in DEP's February 27, 2020 submittal satisfies the pertinent requirements of CAA section 175A(d). EPA notes that while six of the potential contingency measures included in the Commonwealth's second maintenance plan are non-regulatory, their inclusion among other measures is overall SIP-strengthening, and their inclusion does not alter EPA's proposal to find the LMP is fully approvable. EPA also finds that the submittal acknowledges Pennsylvania's continuing requirement to implement all pollution control measures that were contained in the SIP before redesignation of the Harrisburg-Lebanon-Carlisle Area to attainment.

E. Transportation Conformity

Transportation conformity is required by section 176(c) of the CAA. Conformity to a SIP means that transportation activities will not produce new air quality violations, worsen existing violations, or delay timely attainment of the NAAQS (CAA 176(c)(1)(B)). EPA's conformity rule at 40 CFR part 93 requires that transportation plans, programs and projects conform to SIPs and establish the criteria and procedures for determining whether or not they conform. The conformity rule generally requires a demonstration that emissions from the Regional Transportation Plan (RTP) and the Transportation Improvement Program (TIP) are consistent with the motor vehicle emissions budget (MVEB) contained in the control strategy SIP revision or maintenance plan (40 CFR 93.101, 93.118, and 93.124). A MVEB is defined as “that portion of the total allowable emissions defined in the submitted or approved control strategy implementation plan revision or maintenance plan for a certain date for the purpose of meeting reasonable further progress milestones or demonstrating attainment or maintenance of the NAAQS, for any criteria pollutant or its precursors, allocated to highway and transit vehicle use and emissions (40 CFR 93.101).

Under the conformity rule, LMP areas may demonstrate conformity without a regional emission analysis (40 CFR 93.109(e)). However, because LMP areas are still maintenance areas, certain aspects of transportation conformity determinations still will be required for transportation plans, programs and projects. Specifically, for such determination, RTPs, TIPs and transportation projects still will have to demonstrate that they are fiscally constrained (40 CFR 93.108), meet the criteria for consultation (40 CFR 93.105 and 93.112) and transportation control measure implementation in the conformity rule provisions (40 CFR 93.113). Additionally, conformity determinations for RTPs and TIPs must be determined no less frequently than every four years, and conformity of transportation plan and TIP amendments and transportation projects is demonstrated in accordance with the timing requirements specified in 40 CFR 93.104. In addition, for projects to be approved, they must come from a currently conforming RTP and TIP (40 CFR 93.114 and 93.115). The Harrisburg-Lebanon-Carlisle Area remains under the obligation to meet the applicable conformity requirements for the 1997 ozone NAAQS.

III. Proposed Action

EPA's review of DEP's February 27, 2020 submittal indicates that Harrisburg-Lebanon-Carlisle Area second maintenance plan meets the CAA section 175A and all applicable CAA requirements. EPA is proposing to approve the second maintenance plan for the Harrisburg-Lebanon-Carlisle area as a revision to the Pennsylvania SIP. EPA is soliciting public comments on the issues discussed in this document. These comments will be considered before taking final action.

IV. Statutory and Executive Order Reviews

Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the CAA and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this proposed action:

  • Is not a “significant regulatory action” subject to review by the Office of Management and Budget under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
  • Is not an Executive Order 13771 (82 FR 9339, February 2, 2017) regulatory action because SIP approvals are exempted under Executive Order 12866.
  • Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
  • Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.);Start Printed Page 54960
  • Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4);
  • Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);
  • Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
  • Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);
  • Is not subject to requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and
  • Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994

In addition, this proposed rulemaking, proposing approval of pertaining Pennsylvania's second limited maintenance plan for Harrisburg-Lebanon-Carlisle area, does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country located in the State, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law.
