RE: MATS Quarterly Gompliance Report,40 CFR 63 Subpart UUUUU, Huntington Power Plant
(Title V Permit #1501001005) Boiler Units 1 and 2.
Dear Mr. Bird:
The reporting requirements for periodic compliance reports changed beginning on January 1,2024.
$63.10031(g) requires MATS affected sources to begin submitting quarterly compliance reports beginning
with the first calendar quarter o12024 using applicable data elements found in Appendix E to Subpart
UUUUU.
Huntington Power Plant's Title V Permit Conditions 11.B.2.9.3 and 11.8.3.f.3 require the Huntington Plant
submit Compliance Reports according to the requirements of 40 CFR 563.10031(b). This submittal
covers the period from April 1,2024, to June 30,2024, and is intended to satisfy those requirements.
I am authorized to make this submission on behalf of the owners and operators of the affected source or
affected units for which the submission is made. I certify under penalty of law that I have personally
examined, and am familiar with, the statements and information submitted in this document and all its
attachments. Based on my inquiry of those individuals with primary responsibility for obtaining the
information, I certify that the statements and information are to the best of my knowledge and belief true,
accurate, and complete. I am aware that there are significant penalties for submitting false statements
and information, or omitting statements and information, including the possibility of fine or imprisonment.
Should you have any questions regarding this information, please contact Terry Guthrie, Hunter and
Huntington Plant Environmental Manager (435) 6874334 or me at [phone].

ldentification of eachhazardous air pollutant monitored at the affected source
L Non-Mercury HAPS metals using a quarterly filterable particulate matter (PM) stack
test as a surrogate to demonstrate compliance. On April3,20l8 the Utah Department
of Environmental Quality - Division of Air Quality agreed that the Huntington Plant
Unit I met the requirements to qualiff as a low emitting EGU (LEE) unit. The
Huntington Plant submitted a summary table showing three years of quarterly test data.
Each particulate matter (PM) testing result was below one-half of the 0.030 lblN4MBtu
limit or 0.015 lb/MMBtu as required by the subpart.
IL Acid gases using sulfur dioxide (SOz) as a surrogate to demonstrate compliance by an
SOz continuous emissions monitoring system (CEMS).
III. Mercury (Hg), compliance demonstrated by an annualEPA Method 30B sorbent trap
test to re-confirm LEE status.
A brief description of the process unit
L Huntington Unit I is an Electric Utility Steam Generating Unit, designed as a bottom
tangentially-fired boiler, designed by Babcock and Wilcox.
i. Rated Heat Input Capacity of 4,960 MMBtufrr.
ii. The unit is equipped with the following add-on controls:
L Pulse Jet Fabric Filter (baghouse)
2. Wet Flue Gas Desulfurization (wet scrubber)
3. Low-NOx burner technology, with separated over-fire air
iii. Fuels used are sub-bituminous coal using #2 fuel oil for startup fuel when
needed.
II. Unit Category
i. Unit 1 is an existing coal-fired unit combusting non-low rank virgin coal
demonstrating compliance with the emission limits found in Table 2 to Subpart
UUUUU of Part 63
III. The emission and operating parameter limitationsi. Filterable PM quarterly stack testing demonstrating compliance with a 0.030
lb/l\4MBtu emission limit. The unit has demonstrated and achieved low
emitting EGU (LEE) status.
ii. SOz CEMS as a surrogate for acid gases reporting hourly averages in units of
lb/MMBtu demonstrating compliance with a 30 boiler-operating-day average
limit of 0.20 lb/t\4MBtu.
iii. Hg annual EPA Method 30B sorbent trap test reporting hourly averages in
units of lb/TBtu demonstrating compliance with a 30 boiler-operating-day
average of 1.2 lb/TBtu.
A description of any changes in CMS, processes, or controls since the last reporting
period
No changes occurred during the reporting period that would affect compliance to MATS.

April 1, 2024, to June 30,2024
Section 1.0 - Unit 2 Report Summary
Name and address of the affected source
Huntington Power Plant,6 miles west of Huntington Utah on Hwy 31
P.O. Box 680
Huntington, Utah 84528
Identification of each hazardous air pollutant monitored at the affected source
I. Non-Mercury HAPS metals using a quarterly filterable particulate matter (PM) stack
test as a surrogate to demonstrate compliance. On April3,20l8 the Utah Department
of Environmental Quality - Division of Air Quality agreed that the Huntington Plant
Unit 2 met the requirements to qualify as a low emitting EGU (LEE) unit. The
Huntington Plant submitted a summary table showing three years of quarterly test data.
Each particulate matter (PM) testing result was below one-half of the 0.030 lb/MMBtu
limit or 0.015 lb/MMBtu as required by the subpart.
II. Acid gases using sulfur dioxide (SOz) as a surrogate to demonstrate compliance by an
SOz continuous emissions monitoring system (CEMS).
IIL Mercury (Hg), compliance demonstrated by an annual EPA Method 30B sorbent trap
test to re-confirm LEE status.
I.
A brief description of the process unit
Huntington Unit 2 is an Electric Utility Steam Generating Unit, designed as a bottom
tangentially-fired boiler, designed by Babcock and Wilcox.
i. Rated Heat Input Capacity of 4,960 MMBtu/hr.
ii. The unit is equipped with the following add-on controls:
1. Pulse Jet Fabric Filter (baghouse)
2. Wet Flue Gas Desulfurization (wet scrubber)
3. Low-NOx burner technology, with separated over-fire air
iii. Fuels used are sub-bituminous coal using #2 fuel oil for startup fuel when
needed.
Unit Category
i. Unit 1 is an existing coal-fired unit combusting non-low rank virgin coal
demonstrating compliance with the emission limits found in Table 2 to Subpart
UUUUU of Part 63
The emission and operating parameter limitations
i. Filterable PM quarterly stack testing demonstrating compliance with a 0.030
lb/I\4MBtu emission limit. The unit has demonstrated and achieved low
emitting EGU (LEE) status.
ii. SOz CEMS as a surrogate for acid gases reporting hourly averages in units of
lb/IvtMBtu demonstrating compliance with a 30 boiler-operating-day average
limit of 0.20 lbAvIMBtu.
II.
II I.
ur. Hg annual EPA Method 30B sorbent trap test reporting hourly averages in
units of lb/TBtu demonstrating compliance with a 30 boiler-operating-day
average of 1.2 lb/TBtu.
A description of any changes in CMS, processes, or controls since the last reporting
period
No changes occurred during the reporting period that would affect compliance to MATS.
