Potential Violation(s)

On November 15, 2023, an inspector from the DAQ observed Cintas Corporation located at 1671
South 4370 West, Salt Lake City, in Salt Lake County, Utah.

At the time of the inspection the DAQ documented the following potential violation: a total of 14
space heaters on site when only 12 are permitted, as well as 6 HVAC units on the roof with only 4
permitted. Additionally, the input ratings listed on the AO do not match the inputs on the
manufacturer’s plates on the space heaters.

AO Conditions/Rules
UAC R307-401-5 states:

(1) Except as provided in Sections R307-401-9 through R307-401-17, any person subject to
Rule R307-401 shall submit a notice of intent to the director and receive an approval
order precedent to the construction, modification, installation, establishment, or
relocation of an air pollutant source or indirect source. The notice of intent shall be in a
format specified by the director.

DAQE-AN107980010-15 condition I.3 states:

Modifications to the equipment or processes approved by this AO that could affect the emissions
covered by this AO must be reviewed and approved. [R307-401-1]

The purpose of a Compliance Advisory (CA) is to document observations made by the DAQ. You are
responsible for complying with the Utah Air Conservation Rules. There are possible administrative and
civil penalties for failing to do so. Section 19-2-115 of the Utah Code Annotated provides that violators
of the Utah Air Conservation Act and/or any order issued there under may be subject to a civil penalty
of up to $10,000 per day for each violation.

The written response to this CA will be considered in resolving the deficiencies documented in this
letter. It may include information demonstrating compliance with the regulations or a schedule to bring
your company back into compliance with the applicable regulations. The DAQ will review your
response and this CA may be revised as a result of that review. Failure to respond in writing within ten
(10) business days of receipt of this CA will be considered in any subsequent enforcement action and
the assessment of penalties.

Possible DAQ actions to resolve a CA include: No Further Action Letter, Warning Letter, Early
Administrative Settlement with reduced civil penalty, Settlement Agreement with civil penalty, or
Notice of Violation and Order to Comply.

This CA does not limit or preclude the DAQ from pursuing enforcement options concerning this
inspection. Also, this CA does not constitute a bar to enforcement action for conditions that the DAQ
did not observe or evaluate, or any other conditions found during future inspections.

A meeting may be requested to discuss this CA. Please contact Daniel Riddle at 385-222-1357 or
[e-mail] if you would like to request a meeting or if you have any questions about this letter.
