PROPOSED RULEMAKING
ENVIRONMENTAL QUALITY BOARD
[ 25 PA. CODE CHS. 121 AND 127 ]
Additional Requirements for Control of Fine Particulate Matter in the Nonattainment New Source Review Program
[49 Pa.B. 1146]
[Saturday, March 16, 2019]The Environmental Quality Board (Board) proposes to amend Chapters 121 (relating to general provisions) and 127, Subchapters E and H (relating to new source review; and general plan approvals and operating permits) to read as set forth in Annex A. This proposed rulemaking would incorporate recently promulgated Federal requirements for the regulation of volatile organic compounds (VOC) and ammonia as precursor emissions to the formation of fine particulate matter, which is particulate matter less than and equal to 2.5 micrometers in diameter (PM2.5). This proposed rulemaking would also revise the application submission options for the use of general plan approvals and operating permits for portable sources in § 127.641(c) (relating to application for use of plan approvals and operating permits for portable sources).
This proposed rulemaking is necessary to address a mandatory 18-month sanction clock, in accordance with section 179 of the Clean Air Act (CAA) (42 U.S.C.A. § 7509), following the United States Environmental Protection Agency's (EPA) determination that the Commonwealth has not met its obligations for the nonattainment new source review (NNSR) permit program, because its existing NNSR program does not include emissions of VOC and ammonia as PM2.5 precursors. To stop the sanction clock, the Commonwealth will need to submit this proposed rulemaking to the EPA, for the EPA's technical and administrative review, by November 7, 2019.
This proposed rulemaking will be submitted to the EPA for approval as a revision to the Commonwealth's State Implementation Plan (SIP) following promulgation of the final-form rulemaking.
This proposed rulemaking is given under Board order at its meeting of December 18, 2018.
A. Effective Date
This proposed rulemaking will be effective upon final-form publication in the Pennsylvania Bulletin.

C. Statutory Authority
This proposed rulemaking is authorized under section 5(a)(1) of the Air Pollution Control Act (APCA) (35 P.S. § 4005(a)(1)), which grants the Board the authority to adopt rules and regulations for the prevention, control, reduction and abatement of air pollution in this Commonwealth. Section 5(a)(8) of the APCA also grants the Board the authority to adopt rules and regulations designed to implement the provisions of the CAA (42 U.S.C.A. §§ 7401—7671q).
D. Background and Purpose
On July 18, 1997, the EPA revised the National Ambient Air Quality Standard (NAAQS) for particulate matter (PM) to add new standards for fine particles, using PM2.5 as the indicator. The EPA set the health-based (primary) and welfare-based (secondary) PM2.5 annual standard at a level of 15 micrograms per cubic meter (µg/m3) and the 24-hour standard at a level of 65 µg/m3. See 62 FR 38652 (July 18, 1997). Subsequently, on October 17, 2006, the EPA revised the primary and secondary 24-hour NAAQS for PM2.5 to 35 µg/m3 from 65 µg/m3. See 71 FR 61236 (October 17, 2006). On January 15, 2013, the EPA lowered the health-based (primary) PM2.5 annual standard from 15 µg/m3 to 12 µg/m3. See 78 FR 3086 (January 15, 2013).
On January 15, 2015, the EPA designated five areas in this Commonwealth as moderate nonattainment areas for the 2012 annual PM2.5 NAAQS, based on air quality monitoring data from 2011—2013. See 80 FR 2206 (January 15, 2015). The nonattainment areas were the Allegheny County Area, Allentown Area (Lehigh and Northampton Counties), Delaware County Area, Johnstown Area (Cambria County and partial Indiana County) and Lebanon County Area.
On April 7, 2015, the EPA issued updated designations, based on complete, quality-assured and certified monitoring data from 2012—2014, which reduced the number of nonattainment areas in this Commonwealth to three: the Allegheny County Area, the Delaware County Area and the Lebanon County Area. See 80 FR 18535, 18549 (April 7, 2015).
The EPA subsequently determined that two of these areas—Delaware and Lebanon—attained the 2012 annual PM2.5 NAAQS based on complete, quality-assured and certified air quality data that shows that the area is monitoring attainment (Clean Data Determination). See 81 FR 89868 (December 13, 2016) and 82 FR 50851 (November 2, 2017) respectively. These final actions suspended the requirements for the Commonwealth to submit an attainment demonstration and associated reasonably available control measures, reasonable further progress plans, contingency measures and other planning SIP revisions related to the areas' attainment of the 2012 annual PM2.5 NAAQS for so long as these areas continue to attain the 2012 annual PM2.5 NAAQS.
Section 172(c)(3) of the CAA (42 U.S.C.A. § 7502(c)(3)) requires a comprehensive emissions inventory, which is not suspended by the Clean Data Determinations. The Department submitted emissions inventories for the Delaware County and Lebanon County nonattainment areas on May 5, 2017, and September 25, 2017, respectively. On July 3, 2018, the EPA published a final rule that approved both Delaware County and Lebanon County emissions inventories. See 83 FR 31064 (July 3, 2018).
In August 2016, the EPA published its SIP Requirements Rule, which requires states with nonattainment areas for PM2.5 to amend their NNSR regulations to include emissions of VOC and ammonia as PM2.5 precursors. See Fine Particulate Matter National Ambient Air Quality Standards: State Implementation Plan Requirements, 81 FR 58010 (August 24, 2016). Section 189(a)(2)(B) of the CAA (42 U.S.C.A. § 7513a(a)(2)(B)) and its implementing regulations at 40 CFR 51.1003(a) (relating to attainment plan due dates and submission requirements) requires all moderate nonattainment area elements to be submitted to the EPA for SIP approval no later than 18 months from the date of designation. The designations were effective on April 15, 2015. See 80 FR 2206, 18535 (January 15, 2015) and (April 7, 2015). Accordingly, the required elements were due to the EPA for SIP approval on October 15, 2016. The Clean Data Determinations for the Delaware and Lebanon County Areas do not relieve the Commonwealth of its responsibilities to develop this SIP revision for the NNSR permit program.
This proposed rulemaking amends the § 121.1 (relating to definitions) definition of ''regulated NSR pollutant'' and the Chapter 127 Subchapter E NNSR permitting regulations to include the PM2.5 precursor emissions provisions under the SIP Requirements Rule.
In May 2008, the EPA issued its Implementation Rule which defines a major facility as having the potential to emit: 100 tons per year (TPY) of emissions of VOC or ammonia, or both, in a moderate PM2.5 nonattainment area and 70 TPY of VOC or ammonia emissions, or both, in a serious PM2.5 nonattainment area. See Implementation of the New Source Review (NSR) Program for Particulate Matter Less Than 2.5 Micrometers (PM2.5), 73 FR 28321 (May 16, 2008). The EPA's Implementation Rule also established a VOC significance threshold of 40 TPY. The Implementation Rule requires states to determine the ammonia significance threshold and the VOC and ammonia offset ratio. The Clean Data Determinations for the Delaware and Lebanon County Areas do not relieve the Commonwealth of its responsibilities to develop this SIP revision for the NNSR permit program.
This proposed rulemaking amends the § 121.1 definitions of ''major facility'' and ''significant'' and the Chapter 127 Subchapter E NNSR permitting regulations related to the VOC and ammonia offset ratio provisions under the Implementation Rule. On November 4, 2016, the South Coast Air Quality Management District (SCAQMD) amended its NNSR program to include ammonia and VOC as precursors to PM2.5 (SCAQMD Rule 1325). As part of that rulemaking, SCAQMD added a significance threshold for ammonia of 40 TPY, which is the same significance threshold in this proposed rulemaking. SCAQMD also included an offset ratio for VOC and ammonia of 1:1, which is the same offset ratio in this proposed rulemaking. On May 8, 2017, the California Air Resources Board submitted a SIP revision to the EPA with the amendments to SCAQMD Rule 1325. On November 30, 2018, the EPA issued a conditional approval of the SIP revision. See 83 FR 61551 (November 30, 2018).
The Department believes that SCAQMD's technical rationale, that 40 TPY for ammonia is conservative because NOx emissions with an established 40 TPY threshold have a greater influence in the formation of secondary ambient PM2.5 than ammonia emissions, is technically sound. See Proposed Amended Rule 1302—Definitions and Proposed Amended Rule 1325—Federal PM2.5 New Source Review Program, Final Staff Report, November 2016, Mike Laybourn, Air Quality Specialist, South Coast Air Quality Management District. The Department adopts that rationale as its own for this proposed rulemaking.
This proposed rulemaking includes a significant impact level (SIL) of 1.2 µg/m3 for 24-hour PM2.5 and 0.2 µg/m3 for annual PM2.5 which conform with the EPA guidance document for SILs entitled, Guidance on Significant Impact Levels for Ozone and Fine Particles in the Prevention of Significant Deterioration Permitting Program, EPA memorandum, April 17, 2018, Peter Tsirigotis, Director, United States Environmental Protection Agency, Office of Air Quality Planning and Standards, Research Triangle Park, NC 27711.
The addition of PM2.5 SILs will mitigate the effects of PM2.5 in nonattainment areas affected by PM2.5 emissions from attainment areas. A SIL defines the level of ambient air impact that is considered a ''significant contribution'' to air quality. If the modeled maximum ambient impacts of a new source or modification are below the SILs, the source: (1) is presumed not to cause or contribute significantly to a Prevention of Significant Deterioration (PSD) increment or NAAQS violation, and (2) is not required to perform the multiple-source, cumulative impacts assessments that are otherwise required under PSD.
On April 6, 2018, the EPA published a notice of finding of failure to submit (FFS) SIP revisions for the 2012 annual PM2.5 NAAQS, effective May 7, 2018. See 83 FR 14759 (April 6, 2018). The EPA's FFS included a determination that the Commonwealth has not met its obligations for the NNSR permit program for Allegheny, Delaware and Lebanon Counties because emissions of VOCs and ammonia are not currently regulated as PM2.5 precursors. In addition, the FFS included a determination that the following required SIP elements were not submitted for Allegheny County: emissions inventory, control strategy, attainment demonstration, reasonable further progress, qualitative milestones and contingency measures. Because the Allegheny County Health Department is an approved local air pollution control agency under section 12(b) of the APCA (35 P.S. § 4012(b)), it is developing its own SIP revision to address these required SIP elements which the Department will submit to the EPA. In accordance with section 179 of the CAA, a mandatory 18-month sanction clock began on May 7, 2018, the effective date of the FFS.
Therefore, to stop the sanction clock and correct the deficiency that the Commonwealth has not met its obligations for the NNSR permit program, because the Commonwealth's existing NNSR program does not include VOC and ammonia as PM2.5 precursors, one of the following must occur by November 7, 2019:
1) The Commonwealth submits an updated NNSR regulation that addresses VOC and ammonia as PM2.5 precursors as a SIP revision, which the EPA determines to be technically and administratively complete; or
2) The Commonwealth submits a SIP revision for each nonattainment area, and the EPA fully approves and redesignates the area from nonattainment to attainment. Once an area is redesignated as attainment, NNSR would no longer apply.
The Department is currently working on both options to correct the deficiency to ensure that the sanction clock stops by November 7, 2019. Section 179 of the CAA authorizes the EPA to use two types of sanctions: 1) imposing what are called ''2:1 offsets'' on new or modified sources of emissions; and 2) withholding of certain Federal highway funds. Under section 179 of the CAA and its implementing regulations, the Administrator first imposes ''2:1 offsets'' sanctions for new or modified major stationary sources in the nonattainment area, and then, if the deficiency has not been corrected within 6 months, also applies Federal highway funding sanctions. See 40 CFR 52.31 (relating to selection of sequence of mandatory sanctions for findings made pursuant to section 179 of the Clean Air Act). Therefore, if the deficiency is not corrected, the EPA will impose mandatory ''2:1 offsets'' sanctions beginning November 7, 2019, and highway fund sanctions beginning May 7, 2020. The Commonwealth receives approximately $1.7 billion in Federal transportation funding annually, which would be at risk if the Commonwealth does not implement one of the previously listed options.
This proposed rulemaking would also revise the application submission options for the use of general plan approvals and operating permits for portable sources in § 127.641(c). Currently applications may only be delivered through hand delivery or certified mail return receipt requested. The proposed change would remove these options thereby allowing delivery by any means.
This proposed rulemaking would help assure that the citizens of this Commonwealth benefit from reduced emissions of PM2.5 and PM2.5 precursors from regulated sources. Attaining and maintaining levels of PM2.5 below the health-based and welfare-based NAAQS is important to reduce premature mortality and other health and environmental effects associated with PM2.5 exposure.
This proposed rulemaking was presented to the Small Business Compliance Advisory Committee on July 25, 2018, and to the Air Quality Technical Advisory Committee on August 2, 2018. Neither committee expressed concerns, and both committees voted unanimously to concur with the Department's recommendation to present this proposed rulemaking to the Board for consideration.
On August 21, 2018, this proposed rulemaking was presented to the Citizens Advisory Council's (CAC) Policy and Regulatory Oversight (PRO) Committee. The PRO Committee requested that clarity be provided in § 121.1 under the definition of ''major facility'' to indicate that the proposed rulemaking language of ''Seventy TPY of PM2.5, NOx, SO2, VOCs or ammonia in a serious nonattainment area for PM2.5'' means 70 TPY for each pollutant individually and not combined. The Department agreed and revised the definition to provide the requested clarification. On September 18, 2018, the full CAC concurred with the Department's recommendation to move this proposed rulemaking forward to the Board for consideration.
E. Summary of Regulatory Requirements
This proposed rulemaking would amend the existing definitions of ''major facility,'' ''regulated NSR pollutant'' and ''significant'' under § 121.1 to include the requirements for PM2.5 precursors of VOC and ammonia.
Section 127.202 (relating to effective date) is proposed to be amended to include references to PM2.5 precursors. In addition, other minor editorial changes are proposed for this section.
Section 127.203 (relating to facilities subject to special permit requirements) is proposed to be amended to include annual and 24-hour significance levels for PM2.5.
Section 127.210 (relating to offset ratios) is proposed to be amended to include offset ratios for VOCs and ammonia as PM2.5 precursors.
This proposed rulemaking would amend Chapter 127, Subchapter H to provide the regulated community with flexibility in submitting applications to use portable source general permits. Currently, § 127.641(c) requires these applications to be either hand delivered or transmitted by certified mail return receipt requested. The proposed amendment would remove these limited options and allow submission by any means.
F. Benefits, Costs and Compliance
Benefits
As noted in Section D of this preamble, the citizens of this Commonwealth will benefit from reduced emissions of PM2.5 and PM2.5 precursors from regulated sources. Attaining and maintaining levels of PM2.5 below the health-based and welfare-based NAAQS is important to reduce premature mortality and other health and environmental effects associated with PM2.5 exposure. Reductions in ambient levels of PM2.5 would also promote improved animal health and welfare, improved visibility, decreased soiling and materials damage, and decreased damage to plants and trees. Also, regarding portable source general plan approvals and operating permits, allowing for additional flexibility would provide additional options for the regulated community to submit applications that may be faster and less expensive than what is currently allowed.
Compliance costs
This proposed rulemaking would apply to owners and operators of new or modified major facilities with emissions of VOCs or ammonia as PM2.5 precursors located within PM2.5 nonattainment areas or that are located within PM2.5 attainment areas and would have a significant impact to a PM2.5 nonattainment area. The significant impact is determined by the proposed SIL of 1.2 µg/m3 for 24-hour PM2.5 and 0.2 µg/m3 for annual PM2.5. It is not expected that any facilities within PM2.5 attainment areas will have a significant impact on PM2.5 nonattainment areas. No new facilities are known to be constructed or planned to be constructed within PM2.5 nonattainment areas that will emit major amounts of VOCs or ammonia. There are 17 facilities that have the potential to emit 100 TPY or greater of emissions of VOCs, ammonia, or both. The owners and operators of these facilities would be subject to this proposed rulemaking if major modifications occur at the affected facilities for VOCs, ammonia, or both, at the facility. The Department is not aware of any upcoming major modifications at these facilities.
In addition, owners and operators of portable sources would be affected when submitting applications to the Department for a general plan approval or operating permit. Currently, these applications are required to be either hand delivered or transmitted by certified mail return receipt requested. This proposed rulemaking would remove the language on specific requirements and replace it with the ability to submit applications to the Department by any means.
Compliance assistance plan
The Department plans to educate and assist the public and regulated community in understanding the proposed requirements and how to comply with them. This would be accomplished through the Department's ongoing compliance assistance program. The Department would also work with the Small Business Assistance Program to aid the owners and operators of facilities less able to handle matters with their in-house staff.
Paperwork requirements
There are no additional paperwork requirements associated with this proposed rulemaking with which industry would need to comply.
G. Pollution Prevention
The Pollution Prevention Act of 1990 (42 U.S.C.A. §§ 13101—13109) established a National policy that promotes pollution prevention as the preferred means for achieving State environmental protection goals. The Department encourages pollution prevention, which is the reduction or elimination of pollution at its source, through the substitution of environmentally friendly materials, more efficient use of raw materials and the incorporation of energy efficiency strategies. Pollution prevention practices can provide greater environmental protection with greater efficiency because they can result in significant cost savings to facilities that permanently achieve or move beyond compliance.
This proposed rulemaking would help assure that the citizens of this Commonwealth would benefit from reduced emissions of PM2.5 and PM2.5 precursors from regulated sources. Attaining and maintaining levels of PM2.5 below the health-based and welfare-based NAAQS is important to reduce premature mortality and other health and environmental effects associated with PM2.5 exposure. Reduced levels of PM2.5 would promote improved visibility, decreased soiling and decreased materials damage.
H. Sunset Review
The Board is not establishing a sunset date for this proposed rulemaking, since it is needed for the Department to carry out its statutory authority. The Department will closely monitor this proposed rulemaking after promulgation as a final-form rulemaking in the Pennsylvania Bulletin for its effectiveness and recommend updates to the Board as necessary.
I. Regulatory Review
Under section 5(a) of the Regulatory Review Act (71 P.S. § 745.5(a)), on February 25, 2019, the Department submitted a copy of this proposed rulemaking and a copy of a Regulatory Analysis Form to the Independent Regulatory Review Commission (IRRC) and to the Chairpersons of the House and Senate Environmental Resources and Energy Committees. A copy of this material is available to the public upon request.
Under section 5(g) of the Regulatory Review Act, IRRC may convey comments, recommendations or objections to this proposed rulemaking within 30 days of the close of the public comment period. The comments, recommendations or objections must specify the regulatory review criteria in section 5.2 of the Regulatory Review Act (71 P.S. § 745.5b) which have not been met. The Regulatory Review Act specifies detailed procedures for review, prior to final publication of the rulemaking by the Department, the General Assembly and the Governor.
