MEMORANDUM

TO: FILE – INTERMOUNTAIN HEALTHCARE – Utah Valley Hospital

THROUGH: Chad Gilgen, Minor Source Compliance Section Manager

FROM: Daniel Riddle, Environmental Scientist

DATE: January 17, 2024

SUBJECT: FULL COMPLIANCE EVALUATION, Minor, Utah County

INSPECTION DATE: November 8, 2023

SOURCE LOCATION: 1034 North 500 West

OPERATING STATUS: Operating normally at time of inspection.

PROCESS DESCRIPTION: Hospital Mechanical Plant: The plant provides hot water and
steam for the hospital's kitchen, sterilizer, heating and cooling
systems, and water supply. There are three natural gas (diesel
backup) boilers installed in 2013, rated each at 20.4 MMBTU/hr.
One boiler is in operation at all times; the others serve as
back-up. Water passing through the hot tubes in each boiler is
heated by conduction, creating steam used in the hospital
kitchen, sterilizer, and heating system. Condensed steam (hot
water) is fed into the hot water lines and circulated throughout
the hospital. The boilers are fired on natural gas and use diesel
only during periods of natural gas curtailment. Emissions from
the boiler burners are vented through each boiler's 18" diameter
roof vent.

Emergency Generators: The Intermountain Healthcare Utah
Valley Hospital operates five diesel emergency generators,
which provide electricity in the event of a power outage.
Electricity is normally provided by Provo City Power. Emissions
are vented through 4" diameter stacks located on the roof.

Utah Valley Outpatient Clinic: There are four boilers; two 7.0
MMBTU/hr. hydronic boilers; 2 steam boilers - one rated 1.68
MMBTU/hr. and the other one rated at 0.75 MMBTU/hr.

Section III: APPLICABLE FEDERAL REQUIREMENTS

In addition to the requirements of this AO, all applicable provisions of the following federal programs
have been found to apply to this installation. This AO in no way releases the owner or operator from any
liability for compliance with all other applicable federal, state, and local regulations including UAC
R307.
6
NSPS (Part 60) Dc: Standards of Performance for Small Industrial-Commercial-Institutional Steam Generating
Units

Status: In Compliance. The applicable requirement associated with this subpart is to maintain records
of natural gas use. This requirement is satisfied as all-natural gas consumed at the source location is
provided by the local natural gas utility and the source maintains monthly records of all-natural gas use
at the source location. The boilers are permitted to occasionally use fuel oil. Hours of usage are listed
above; see Condition II.B.3.b for more details. The source is also required to submit semi-annual
reports detailing the hours of diesel fuel use, along with verification that the diesel is ULSD. See the
attached report for January – June 2023, as well as the ULSD invoice.

NSPS (Part 60) IIII: Standards of Performance for Stationary Compression Ignition Internal Combustion
Engines

Status: In Compliance. This subpart is applicable to all diesel-fired emergency generators at the source
location manufactured after April 1, 2006. Compliance with this subpart is satisfied by maintaining and
operating the engines in accordance with manufacturer's instructions, use of low sulfur diesel fuel, and
not exceeding 100 hours per year for non-emergency use. The source confirmed they operate the
generators in accordance with manufacturer's instructions with maintenance being conducted per the
manufacturer's specifications. Each engine is equipped with a non-resettable hour meter.

MACT (Part 63) ZZZZ: National Emissions Standards for Hazardous Air Pollutants for Stationary
Reciprocating Internal Combustion Engines

Status: In Compliance. Stationary RICE located at area sources of HAP emissions must comply with
Table 2d to subpart ZZZZ of MACT (Part 63), which requires annual maintenance of hoses, oil, belts,
and filters, and the use of ultra-low sulfur fuel. The engine is run less than 100 hours per calendar year
for non-emergency purposes, as required by ZZZZ. A non-resettable hour meter was observed at the
time of inspection.

AREA SOURCE RULES EVALUATION:

The following Area Source Rules were evaluated during this inspection:
Emission Standards: Sulfur Content of Fuels [R307-203]

Status: In Compliance. Only ULSD is used at this source. See the attached fuel invoice from
Christensen Oil Company.

Standards of Performance for New Stationary Sources [R307-210]

Status: Compliance with this area source rule is satisfied by compliance with Federal Requirements
NSPS (Part 60) Subparts Dc and IIII. See Section III above for more information.

National Emission Standards for Hazardous Air Pollutants [R307-214]

Status: Compliance with this area source rule is satisfied by compliance with Federal Requirement
MACT (Part 63) Subpart ZZZZ. See section III above for more information.

Nonattainment and Maintenance Areas for PM10: Emission Standards [R307-305]

Status: No visible emissions were observed from any point at the time of inspection. See attached
VEO Form for additional information.

COMPLIANCE STATUS &
RECOMMENDATIONS: In regards to Approval Order (AO) DAQE- AN108170003-18,
dated December 17, 2018: In compliance at the time of
inspection. The facility appears to be well maintained and
operated.

HPV STATUS: Not Applicable.

RECOMMENDATION FOR
NEXT INSPECTION: Inspect as usual. The ethylene oxide sterilizer process was
permanently shut down in March 2019. Consequently, the two
ethylene oxide sterilizers in AO II.A.2 are no longer there.
Ensure that they are still submitting semi-annual Subpart Dc
reports for use of fuel oil in the boilers.

NSR RECOMMENDATIONS: Remove ethylene oxide sterilizers from AO.

Thanks David - taking a second look at the documents you sent, I actually need the rolling 12-month total for fuel oil
usage in the boilers. Could you send me the hours for November 2022 - October 2023? This is according to Condition
II.B.3.b.
Additionally, as required by Condition II.B.4.a.1, I need the rolling 12-month total hours of usage for each emergency
generator engine (for non-emergency purposes). Please send the same time from from November 2022 - October 2023.
Thank you,

Daniel,

Dave is out on leave until the end of December. I am working with the facility to get the rolling 12-month usage. It may
take a few days for me to track this down. I do know they have it.

Jim - thanks for sending that over. Taking a second look at the boiler hours for diesel usage, only six months were
included from January 2023 to June 2023. The AO asks for the rolling 12 month total. I'm sure that total will also be well
below the maximum of 48 hours, but could you send me those hours for each boiler for the same period of November
2022 - October 2023? This is for Condition II.B.3.b in your Approval Order if you need to reference it.
Thanks,
Daniel
