PERMIT HISTORY When issued, the approval order shall supersede (if a modification) or will be based on the
following documents: Supersedes AO DAQE-AN0104610001 dated December 2, 2010
REVIEWER COMMENTS
1. Comment regarding 10-Year Review Updates:
The formatting, language, and primary contact of Approval Order DAQE-AN0104610001-10, dated December 2, 2010, have been updated. The 2010 AO specifies that the fuel type for the emergency engines is diesel fuel. Therefore, a condition requiring that only diesel fuel be used as fuel in the emergency engines has been added to
the updated AO. Condition II.B.2.b of the 2010 AO permits the source to operate each boiler on site for up to 200 hours combined, annually, while combusting fuel oil. Based on the current condition, the boilers are not considered gas-fired boilers. During the 10-year review period, the source confirmed that each
boiler only operates approximately an hour per month on fuel oil for testing and maintenance purposes. Therefore, each boiler is considered to be a natural-gas fired boiler as defined in 40 CFR 63.11237. A gas-fired boiler burns only gaseous fuels during normal operation and burns liquid fuel
only during periods of gas curtailment, gas supply interruption, startups, or periodic testing on liquid fuel. Therefore, the boiler conditions have been updated with the source's approval to reflect the above distinction.
The 2010 AO did not specify PTEs for CO2e. It is assumed the CO2e emissions are primarily released from combustion units on site. Therefore, emissions from the boilers were estimated using 8,760 hours of annual operation and emission factors in AP-42, Chapter 1.4 (Natural Gas Combustion). Emissions from the emergency engine were estimated assuming 100 hours of annual
non-emergency use and emission factors in AP-42, Chapter 3.4 (Large Stationary Diesel and All Stationary Dual-fuel Engines). No changes in equipment or operations are taking place at the facility. The site-wide emission estimates should be updated when the source applies for a modification in the future. [Last updated January 30, 2025] 2. Comment regarding 10-Year Review Equipment List: The 2010 AO specifies the following approved equipment:

Fuel: Diesel Fuel According to a Full Compliance Evaluation (Memorandum DAQC-1234-22, dated September 13, 2022) conducted in 2022, no unapproved equipment was observed. However, additional information for the permitted equipment was provided (see below).
Two (2) 600 HP Boilers: o One (1) boiler is a 25 MMBtu/hr Cleaver-Brooks boiler manufactured in 1987. o One (1) boiler is a 24.5 MMBtu/hr Cleaver-Brooks boiler manufactured in 2002. Two (2) 1,500 kW Emergency Generators: o One (1) Generator is a 2171 HP Caterpillar engine manufactured in 2002.
o One (1) Generator is a 2220 HP Cummins engine manufactured in 2010. Two (2) 1,250 kW Emergency Generators: o Each Generators is a 2220 HP Cummins engine manufactured in 2010. On January 29, 2025, the DAQ reached out to the source representative to confirm if the above equipment was still accurate and if the new AO could be updated accordingly. Permission was granted on January 30, 2025. Therefore, the updated AO includes the ratings and manufacture year of each piece of equipment. The manufacturer/model types will not be included as they do not affect applicable state/federal standards or potential to emit. [Last updated January 30, 2025] 3. Comment regarding Federal Standard Applicability: NSPS Subpart Dc 40 CFR 60 (NSPS) Subpart Dc applies to owners/operators of steam generating unit that has a maximum design heat input capacity of 100 MMBtu/hr or less, but greater than or equal to 10 MMBtu/hr. Steam generating unit means a device that combusts any fuel and produces steam or
heats water or heats any heat transfer medium. The two (2) boilers that the source operates are larger than 10 MMBtu/hr. Therefore, NSPS Subpart Dc applies to this facility. NSPS Subpart IIII 40 CFR 60 Subpart IIII applies to owners and operators of Stationary Compression-Ignition Internal Combustion Engines (CI ICE) that commence construction after July 11, 2005, where the stationary CI ICE is manufactured after April 1, 2006. Some of the diesel-fired CI ICEs at this site were constructed prior to this date, while others were constructed after. Therefore, NSPS Subpart IIII applies to the engines on site that were manufactured after April 1, 2006. MACT Subpart ZZZZ 40 CFR 63 Subpart ZZZZ (National Emissions Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines) applies to owners and operators of stationary internal combustion engines (RICE) at an area source of HAP emissions. Therefore, MACT Subpart ZZZZ applies to the emergency engine on site. MACT Subpart JJJJJJ 40 CFR 63 MACT Subpart JJJJJJ (National Emissions Standards for Hazardous Air Pollutants for Industrial, Commercial, and Institutional Boilers Area Sources) applies to industrial, commercial, or
institutional boilers located at an area source of HAP emissions. The boilers on site are considered institutional boilers. While the boilers on site have the capacity to operate on fuel liquid fuel, they are considered gas-fired boilers as defined in 40 CFR 63.11237. A gas-fired boiler burns only gaseous fuels during normal operation and burns liquid fuel only during periods of gas curtailment,

Engineer Review N104610002: Intermountain Health Primary Children's Hospital - Primary Children's Medical Center January 30, 2025 Page 10
gas supply interruption, startups, or periodic testing on liquid fuel. Natural gas-fired boilers are not subject to MACT Subpart JJJJJJ or to any requirements in MACT Subpart JJJJJJ. Therefore, MACT
Subpart JJJJJJ does not apply to the facility. The dual-fuel boilers on site are permitted to operate on liquid fuel for up to 48 hours during any calendar year for periodic testing, maintenance, or operator training. [Last updated January 30, 2025] 4. Comment regarding Title V Applicability: Title V of the 1990 Clean Air Act (Title V) applies to the following: 1. Any major source 2. Any source subject to a standard, limitation, or other requirement under Section 111 of the Act, Standards of Performance for New Stationary Sources; 3. Any source subject to a standard or other requirement under Section 112 of the Act, Hazardous Air Pollutants. 4. Any Title IV affected source.
This facility is not a Title IV source nor a major source. The facility is not subject to 40 CFR
61(NESHAP) regulations. It is subject to 40 CFR 60 (NSPS) Subparts A, Dc, and IIII and to 40 CFR 63 (MACT) Subparts A and ZZZZ. NSPS Subpart IIII and MACT Subpart ZZZZ each exempt sources from the obligation to obtain a Title V permit provided that the source is not required to
obtain the permit for any other reason. No such reason exists. However, NSPS Subpart Dc does not include this exemption. Boilers that have the capacity to operate on fuel oil are subject to certain standards and limitations under NSPS Subpart Dc. Therefore, Title V applies to this facility as an area source.

The Natural Gas Units are in MCF. I referenced MCG which was on one of my logs and that was not correct. The
attached spreadsheet is updated to reflect MCF.
The Boiler Hours-Generator spreadsheet has been updated to show the time units in Hours. See the attached Updated
sheet.
Let me know if you need any further information.

Good Morning Tyler,
The Natural gas PCH Campus, look good, but I do not understand (MCG)? I was expecting Decatherms as the units.
Second spreadsheet, The format for the Boiler hours is good,Please add time units (hours?). I only need the boiler hours
burning oil. The other information is nice because it gives the big picture.

Greg,
See the attached spreadsheet for the Boiler Run Hours, Boiler Diesel Usage, Boiler Diesel Run Hours. I filled out the
2019 data and wanted to see if this is what is required for reporting. IF this meets the requirements I will fill out the
remaining data for 2016,2017,2018. Thanks for your time.
