Supplemental Information and Data for the Indiana, Pennsylvania Nonattainment Area for the 2010 Sulfur Dioxide Primary National Ambient Air Quality Standard; Notice of Data Availability (NODA), 13602-13603 [2020-04774]

Download as PDF jbell on DSKJLSW7X2PROD with PROPOSALS 13602 Federal Register / Vol. 85, No. 46 / Monday, March 9, 2020 / Proposed Rules the current RPW methodology, ‘‘ODIS– RPW data collectors record a PC Postage mailpiece as IBI and indicate the specific PC Postage manufacturer.’’ Id. at 3. The Postal Service describes several limitations with the current methodology. Id. at 4. ODIS–RPW is a statistical sampling system producing point estimates with sampling errors, and ODIS–RPW tests may cause unintended errors in mail sampling and in recording data elements observed. Id. ODIS–RPW is unable to report on or adjust for underpaid and overpaid mail. Id. By contrast, the proposed methodology uses census transaction data that are not subject to sampling error and would likely produce the same or better data quality. Id. The Postal Service proposes to replace the ODIS–RPW sampling system (current methodology) with census transaction data (proposed methodology) no earlier than FY 2020, Quarter 3 to allow for full implementation of changes to the APV system that become effective on April 1, 2020. Id. at 4–5. It states that the proposed methodology ‘‘provides a complete census source of transactionallevel data for PC Postage domestic mailpieces and makes appropriate APV adjustments at the record level.’’ Id. at 5. Impact. To demonstrate the impact of the proposed methodology, the Postal Service submitted a report comparing FY 2019 RPW results using both the current methodology and proposed methodology.2 This report shows differences by major mail category if the proposed methodology replaced the current methodology in FY 2019. Id. at 6. For First-Class Package Service as well as Media and Library Mail, both revenue and volume would have increased. Id. For USPS Retail Ground and Priority Mail, both revenue and volume would have decreased. Id. For FY 2019, total mail volume would have increased by 0.1 percent, total pounds would have increased by 0.3 percent, and total revenue would have remained unchanged because the RPW report is tied to the Accounting Trial Balance. Id. The Postal Service explains that the differences in the report ‘‘are mainly due to differences in manual data collection (current methodology) compared to postage payment data (proposed methodology).’’ Id. It notes that the differences in the report would not have been as large if the APV system were fully implemented at the beginning of FY 2019. Id. The Postal Service concludes that the proposed methodology change ‘‘will result in the improved reporting of PC Postage non-contract revenue and volume both in terms of the level and measures of precision.’’ Id. at 7. It adds that the proposed methodology change ‘‘will also allow for more granularity in the underlying report data.’’ Id. III.

General Information EPA proposed approval of the Attainment Plan for the Indiana, Pennsylvania Nonattainment Area for the 2010 SO2 NAAQS on July 13, 2018. 83 FR 32606. As part of approving the Attainment Plan, EPA also proposed to approve into the Pennsylvania SIP SO2 emission limits and associated compliance parameters for Keystone, Conemaugh, Homer City and Seward Generating Stations. The public comment period for EPA’s proposal closed on August 13, 2018. During the public comment period, EPA received from one commenter new information and analysis purporting to show that, using an alternative receptor grid, the critical emission values (CEVs) for Seward and Conemaugh Stations modeled a violation of the standard within the boundaries of the nonattainment area (NAA). In response, the Pennsylvania Department of Environmental Protection (PADEP) opted to provide EPA with supplemental information to provide further support for their submitted Attainment Plan. The supplemental information includes: (1) A supplemental air dispersion modeling report, (2) Supplemental air dispersion modeling data, (3) Supplemental air dispersion modeling protocol, (4) A meteorological monitoring plan, (5) Meteorological monitoring data, (6) Meteorological monitoring quality assurance, quality control, and audit reports, (7) Clean Air Markets Division (CAMD) emission data for 2010–2018, and (8) Continuous Emissions Monitoring (CEM) data for 2010–2019 (3rd Quarter). PADEP’s supplemental modeling report provides additional modeling using the newly provided site specific meteorological data to support the SO2 VerDate Sep<11>2014 17:29 Mar 06, 2020 Jkt 250001 emission limits established in the original attainment plan. The study supplements the modeling submitted in 2017 (see Docket EPA–R03–OAR–2017– 0615–0018 which can be located via https://www.regulations.gov) to focus on the area in the NAA near Conemaugh and Seward stations. The meteorological data collection spanned the 13-month period of August 1, 2015 through August 31, 2016. Due to better SOnic Detection And Radar (SODAR) data capture percentages for the September 1, 2015 through August 31, 2016 period, this 12-month period was used for this supplemental modeling analysis. PADEP used AERMOD dispersion model 16 (Version 19191), current as of August 2019, to evaluate air quality impacts from the emission sources of interest. The South Fayette, Pennsylvania monitor, which is located about 62 kilometers to the westsouthwest of the Indiana County NAA, was used to determine the uniform regional background component for the NAAQS SO2 modeling. The most recent 3-year period (2016–2018) of emissions data were used in the modeling analysis and details on the emissions processing are provided in the submittal, which can be found in the docket for this notice. The modeling was used to define CEVs for Seward and Conemaugh Generating Stations that show 99th percentile peak daily 1-hour maximum concentrations (‘‘design concentrations’’) complying with the 1hour SO2 NAAQS. For the Seward and Conemaugh Generating Stations, longerterm emission rates that are discounted from the 1-hour CEV rates were derived. Different averaging times were selected to best fit the emission source profiles at each plant. Conemaugh emission rates are based upon a 3-hour block emission average, and the Seward emission rate is based upon a rolling 30day average. The current SO2 emission limits for the modeled emission sources at the Conemaugh and Seward Stations are lower than the longer-term emission rates that demonstrate attainment with the NAAQS through modeling. To demonstrate that Seward’s rolling 30-day emission limit is protective of the NAAQS, PADEP submitted randomly reassigned emissions (RRE) modeling. One hundred AERMOD simulations were run using randomly reassigned 1-hour emission rates for Seward’s emissions along with constant CEV 1-hour emission rates for the remaining three SO2 sources in the NAA plus regional background (South Fayette monitor for 2016–2018 as discussed in Section 4.7 of the Modeling Report). For each of the 100 modeling runs with one PO 00000 Frm 00026 Fmt 4702 Sfmt 4702 13603 year of on-site meteorology, the 99th percentile peak daily 1-hour maximum at each receptor resulted in design concentrations that comply with the NAAQS. The highest 99th percentile daily maximum SO2 concentration of the 100 model simulations was 190.05 micrograms per meter cubed (mg/m 3) (this occurred in simulation run 44) and is less than the NAAQS (196.4 mg/m 3). The supplemental modeling purports to demonstrate that a lower CEV for Seward Generating Station demonstrates attainment compared to the CEV provided in the original attainment plan. The rolling 30-day emission limit for Seward has remained unchanged. The newly submitted RRE modeling purportedly demonstrates that the rolling 30-day emission limit for Seward is protective of the NAAQS. The CEV for Conemaugh Generating Station has not changed from the original Attainment Plan as a result of the supplemental modeling analysis, and therefore no additional analysis was provided in support of the source’s longer term 3-hour block limit. EPA is seeking comment on the Pennsylvania supplemental information submitted on February 5, 2020 as supporting analysis that shows the previously-established longer term emission limits for Seward and Conemaugh Generating Stations demonstrate attainment of the 2010 SO2 NAAQS in the Nonattainment Area. EPA is not seeking comment on any other aspect of the Attainment Plan, which has already gone through the public comment process from July 13, 2018 through August 13, 2018. Dated: February 24, 2020.

SUPPLEMENTARY INFORMATION: 

I. General Information

    EPA proposed approval of the Attainment Plan for the Indiana, 
Pennsylvania Nonattainment Area for the 2010 SO2 NAAQS on 
July 13, 2018. 83 FR 32606. As part of approving the Attainment Plan, 
EPA also proposed to approve into the Pennsylvania SIP SO2 
emission limits and associated compliance parameters for Keystone, 
Conemaugh, Homer City and Seward Generating Stations. The public 
comment period for EPA's proposal closed on August 13, 2018. During the 
public comment period, EPA received from one commenter new information 
and analysis purporting to show that, using an alternative receptor 
grid, the critical emission values (CEVs) for Seward and Conemaugh 
Stations modeled a violation of the standard within the boundaries of 
the nonattainment area (NAA). In response, the Pennsylvania Department 
of Environmental Protection (PADEP) opted to provide EPA with 
supplemental information to provide further support for their submitted 
Attainment Plan. The supplemental information includes: (1) A 
supplemental air dispersion modeling report, (2) Supplemental air 
dispersion modeling data, (3) Supplemental air dispersion modeling 
protocol, (4) A meteorological monitoring plan, (5) Meteorological 
monitoring data, (6) Meteorological monitoring quality assurance, 
quality control, and audit reports, (7) Clean Air Markets Division 
(CAMD) emission data for 2010-2018, and (8) Continuous Emissions 
Monitoring (CEM) data for 2010-2019 (3rd Quarter).
    PADEP's supplemental modeling report provides additional modeling 
using the newly provided site specific meteorological data to support 
the SO2 emission limits established in the original 
attainment plan. The study supplements the modeling submitted in 2017 
(see Docket EPA-R03-OAR-2017-0615-0018 which can be located via https://www.regulations.gov) to focus on the area in the NAA near Conemaugh 
and Seward stations. The meteorological data collection spanned the 13-
month period of August 1, 2015 through August 31, 2016. Due to better 
SOnic Detection And Radar (SODAR) data capture percentages for the 
September 1, 2015 through August 31, 2016 period, this 12-month period 
was used for this supplemental modeling analysis. PADEP used AERMOD 
dispersion model 16 (Version 19191), current as of August 2019, to 
evaluate air quality impacts from the emission sources of interest. The 
South Fayette, Pennsylvania monitor, which is located about 62 
kilometers to the west-southwest of the Indiana County NAA, was used to 
determine the uniform regional background component for the NAAQS 
SO2 modeling. The most recent 3-year period (2016-2018) of 
emissions data were used in the modeling analysis and details on the 
emissions processing are provided in the submittal, which can be found 
in the docket for this notice.
    The modeling was used to define CEVs for Seward and Conemaugh 
Generating Stations that show 99th percentile peak daily 1-hour maximum 
concentrations (``design concentrations'') complying with the 1-hour 
SO2 NAAQS. For the Seward and Conemaugh Generating Stations, 
longer-term emission rates that are discounted from the 1-hour CEV 
rates were derived. Different averaging times were selected to best fit 
the emission source profiles at each plant. Conemaugh emission rates 
are based upon a 3-hour block emission average, and the Seward emission 
rate is based upon a rolling 30-day average. The current SO2 
emission limits for the modeled emission sources at the Conemaugh and 
Seward Stations are lower than the longer-term emission rates that 
demonstrate attainment with the NAAQS through modeling.
    To demonstrate that Seward's rolling 30-day emission limit is 
protective of the NAAQS, PADEP submitted randomly reassigned emissions 
(RRE) modeling. One hundred AERMOD simulations were run using randomly 
reassigned 1-hour emission rates for Seward's emissions along with 
constant CEV 1-hour emission rates for the remaining three 
SO2 sources in the NAA plus regional background (South 
Fayette monitor for 2016-2018 as discussed in Section 4.7 of the 
Modeling Report). For each of the 100 modeling runs with one year of 
on-site meteorology, the 99th percentile peak daily 1-hour maximum at 
each receptor resulted in design concentrations that comply with the 
NAAQS. The highest 99th percentile daily maximum SO2 
concentration of the 100 model simulations was 190.05 micrograms per 
meter cubed ([mu]g/m \3\) (this occurred in simulation run 44) and is 
less than the NAAQS (196.4 [mu]g/m \3\).
    The supplemental modeling purports to demonstrate that a lower CEV 
for Seward Generating Station demonstrates attainment compared to the 
CEV provided in the original attainment plan. The rolling 30-day 
emission limit for Seward has remained unchanged. The newly submitted 
RRE modeling purportedly demonstrates that the rolling 30-day emission 
limit for Seward is protective of the NAAQS. The CEV for Conemaugh 
Generating Station has not changed from the original Attainment Plan as 
a result of the supplemental modeling analysis, and therefore no 
additional analysis was provided in support of the source's longer term 
3-hour block limit.
    EPA is seeking comment on the Pennsylvania supplemental information 
submitted on February 5, 2020 as supporting analysis that shows the 
previously-established longer term emission limits for Seward and 
Conemaugh Generating Stations demonstrate attainment of the 2010 
SO2 NAAQS in the Nonattainment Area. EPA is not seeking 
comment on any other aspect of the Attainment Plan, which has already 
gone through the public comment process from July 13, 2018 through 
August 13, 2018.
