Fugitive Dust Emissions - Title V Permit Requirements
1.1 PURPOSE AND APPLICABILITY
lntermountain Regional Landfill (lRL) operates under Title V Operating Permit No. 4900334002,
issued to IRL on December 20,2023. Beginning in February 2023, IRL began operating the
Landfill Gas Collection System (LGCS) which includes 39 wellheads, two generators (one primary
and a backup), two blowers (one primary and one backup), and a candlestick flare. An additional
nine wellheads (four East Bench and five C-Lateral) were brought online in February 2024 and
three more wellheads (C-Lateral) in September 2024.
Routine monitoring tasks required by 40 CFR $ 62 Subpart OOO, 40 CFR $ 63 Subpart AAAA
were completed as required. This report encompasses October 1,2024 through December 31,
2024. This report contains the items specified in 40 CFR S 63.1981(h) and is solely intended for
use by the Utah Department of Air Quality (DAO) for purposes of compliance assessment and by
IRL as a facility compliance document. lt should be recognized that this report presents
compliance information specific to the timeframe herein. The compliance status of the facility is
certified in Appendix A.
1.2 BACKGROUND
Non-methane organic compound (NMOC) emissions exceeded the 50 Mg/yr NMOC threshold in
July 2019. A LGCS design was submitted to the Utah Department of Environmental Quality (DEO)
in August 2020 and LGCS construction began in August 2021. The Approval Order (AO) for the
candlestick flare and associated generators was provided to IRL by Utah DAQ in November 2022
followed by the Title V Operating Permit issued on December 20th, 2023.
LGCS startup occurred on January 31,2023 and IRL has continued to tune and update
the wellfield along with bringing additional wellheads online in 2024.
1.3 STARTUP, SHUTDOWN, AND MALFUNCTION EVENTS
40 cFR SS 63.1981(hX1) - 63.1e81(hX4)
IRL began recording collection system and control device startup, shutdown, and malfunction
events as required by 40 CFR S 63 Subpart AAAA beginning in March of 2023, one month after
initial startup.
Shutdown of the flare has occurred periodically due to maintenance activities on the flare,
generators and/or collection field, as well as malfunctions (Table 1). No uncontrolled releases of
hazardous air pollutants have occurred during this reporting period with landfill gas remaining
inside the landfill and collection system when the flare was not operating. This is accomplished
through closure of the block valve at the flare after the header during every flare shutdown as
confirmed by telemetry. Many unexpected shutdowns occurred outside of standard operating
hours, including weekends, and the system was restarted the following work morning.
1.4 LGCS WELLFIELD MONITORING
40 cFR SS 63.1981(hxrXi) - 63.1e81(hxlXiii)
LGCS wellfield monitoring was performed monthly, in accordance with the AO and 40 CFR S 63
Subpart AAAA requirements. The LGCS wellheads are monitored for gas flow and quality at least
once per month to comply with permit conditions and are balanced as needed to optimize gas
extraction from the landfill. Wellheads are monitored for temperature and static pressure for
compliance requirements, and oxygen and nitrogen for operating and tuning parameters (the
nitrogen/orygen compliance requirement has been removed from the newly effective Emissions
Guidelines 40 CFR $ 60 Subpart Cf, 40 CFR S 62 Subpart OOO since June 21 ,2021 and 40 CFR
$ 63 Subpart AAAA since November 12,2020).
Wellhead data was collected from 51 wells in October 2024 through December 2024 as shown in
Appendix B and Figure 1. G1-A1-02 was connected to vacuum but lacked a wellhead for
measurements and is not shown in the table. Otherwise there were no operational parameter
exceedances in this quarter.
1.5 LANDFILL SURFACE EMISSIONS MONITORING
40 cFR S 63.1e81(hxs)
One quarterly (November 2024) landfill surface emission monitoring events was performed during
this reporting period. Surface emissions were measured across the Landfill surface using a
Surface Emission Monitor (SEM) 5000 meeting the specifications of EPA Method 21. The
measurements were made in accordance with federal requirements.
1.5.1 November 2024 Monitoring Event
The fourth quarter monitoring event was conducted on November 20 and 21, 2024. The walking
pattern was conducted following an east to west traverse, as illustrated in Figure 2. A surface
inspection was performed concurrent with the surface emission monitoring to identify cracks,
erosion fissures, or other anomalies in the Landfill cap that may create escape pathways for
methane. Field forms for this quarterly monitoring event are provided in Appendix C. No
exceedances were observed during this monitoring event.
ln addition to the Surface Emission Monitoring event, all penetrations within the lined area of the
active landfill collection system footprint were monitored for methane. No exceedances were
observed during this monitoring event. Field forms for this quarterly monitoring event are provided
in Appendix C.
1.6 VISUAL EMISSION MONITORING
Quarterly observations were conducted on December 16,2024. EPA Method 9 observations were
conducted on stationary sources in accordance with 11.8.1.b.1 & 11.8.3.a.1 of the permit.
Observation data is provided in Appendix D. Due to mechanical issues, no visual emission
observation was conducted on Genset #1 or Genset #2 in December 2024 because of
malfunction. ln order to comply with the duty to minimize emissions (40 CFR 63.1955(c)), a
temporary trailer-mounted mobile generator was utilized in December to continue running the
LGCS and flare. A visual emission observation was performed on the rental replacement
generator shown in Appendix D. No exceedances on permitted or rental replacement generators
were observed during these monitoring events.
1.7 FUGITIVE DUST EMISSIONS
ln accordance with the conditions of Permit Provision ll.B.l.a, the facility has implemented and
continues to implement the most recently approved fugitive dust control plan as required by R307-
309-6 and administers one or more of the contingencies, or Best Management Practices (BMP)
provided for the plan. IRL predominantly utilized water and designated traffic patterns at the facility
to reduce dust. Fugitive dust emission reporting forms are provided in Appendix E.
1.8 SUMMARY
IRL operated in compliance with conditions mandated by the current Title V Operating Permit
during the period covered in this report. These conclusions are based on the data collected by
Hansen, Allen & Luce and/or provided by IRL that are included in this report.
Well G1-A1-02 was connected to vacuum but lacked a wellhead for measurements and is not
shown in the table. Otherwise there were no wellhead operational exceedances this quarter.
Due to mechanical issues, no visual emission observation was conducted on Genset #1 or Genset
#2 in December 2024 because of malfunction. ln order to comply with the duty to minimize
emissions (40 CFR 63.1955(c)), a temporary trailer-mounted mobile generator was utilized in
December to continue running the LGCS and flare. A visual emission observation was performed
on the rental replacement generator. No exceedances on permitted or rental replacement
generators were observed during these monitoring events.
The next semiannualTitle V report is scheduled to be delivered in July 2025.
