dated August 15, 2011 for a 10-Year Review and Permit Updates
Project Number: N114120003

The DAQ requests a company representative review and sign the attached Engineer Review (ER). This
ER identifies all applicable elements of the New Source Review (NSR) permitting program. Geneva
Rock Products, Inc. should complete this review within 10 business days of receipt.

Geneva Rock Products, Inc. should contact Katie Andersen at [phone] if there are questions or
concerns with the review of the draft permit conditions. Upon resolution of your concerns, please email
Katie Andersen at [e-mail] the signed cover letter. Upon receipt of the signed cover letter,
the DAQ will prepare an Approval Order (AO) for signature by the DAQ Director.

If Geneva Rock Products, Inc. does not respond to this letter within 10 business days, the project will
move forward without source concurrence. If Geneva Rock Products, Inc. has concerns that cannot be
resolved and the project becomes stagnant, the DAQ Director may issue an Order prohibiting
construction.

Project Proposal
Administrative Amendment to Approval Order DAQE-AN0114120002-11 dated August 15, 2011
for a 10-Year Review and Permit Updates

Project Description
This is a 10 Year Review. On August 23, 2023, DAQ Compliance noted that most of the
equipment listed in the permit was not on site. Geneva Rock Products confirmed that the
equipment has been removed from the source location. Geneva Rock Products would like to keep
the permit as is for potential future use of the site, thus there are no changes to equipment or
emissions in this 10 Year Review.

EMISSION IMPACT ANALYSIS
This is a 10-Year Review. No changes to equipment or emissions are being made at this time. Therefore,

PERMIT HISTORY

When issued, the approval order shall supersede (if a modification) or will be based on the
following documents:

Supersedes DAQE-AN0114120002-11 dated August 15, 2011

REVIEWER COMMENTS

1. Comment regarding Applicability of R307-312:
R307-312 applies to all crushers, screens, and conveyors located within a PM2.5 nonattainment and
maintenance area. Because this source is located in Cache Valley, Utah, which is a maintenance area
for PM2.5, the source is subject to R307-312. [Last updated May 30, 2024]

2. Comment regarding NSPS IIII & MACT ZZZZ Applicability:
40 CFR 60 NSPS Subpart IIII applies to owners and operators of stationary CI ICE that commence
construction after July 11, 2005 where the stationary CI ICE are manufactured after April 1, 2006
[40 CFR 60.4200(a)(2)(i)]. Beginning October 1, 2010, owners and operators of stationary CI ICE
subject to this subpart with a displacement of less than 30 liters per cylinder that use diesel fuel must
use diesel fuel that meets the requirements of 40 CFR 80.510(b) for nonroad diesel fuel [40 CFR
60.4207(b)]. 40 CFR 80.510(b) has the requirement to use 15 ppm sulfur content fuel.

If 40 CFR 60 NSPS Subpart IIII does not apply, 40 CFR 63 MACT Subpart ZZZZ would still apply.
40 CFR 63 MACT Subpart ZZZZ applies to stationary RICEs at a major or area source of HAP
emissions [40 CFR 63.6585]. The fuel requirement in MACT ZZZZ applies to owners and operators
of existing non-emergency, non-black start CI stationary RICE with a site rating of more than 300
brake HP with a displacement of less than 30 liters per cylinder that uses diesel fuel. Owners and
operators must use diesel fuel that meets the requirements in 40 CFR 80.510(b) for nonroad diesel
fuel [40 CFR 63.6604]. For stationary RICE located at an area source of HAP emissions, a
stationary RICE is existing if you commenced construction or reconstruction of the stationary RICE
before June 12, 2006 [40 CFR 63.6590(a)(1)(iii)]. This requirement is the same as NSPS IIII, which
requires the use 15 ppm sulfur content fuel.

If an engine is manufactured prior to 2006 and larger than 300 hp, it would be required to use 15
ppm sulfur content fuel according to MACT ZZZZ. If an engine is manufactured after 2006, it
would be required to use 15 ppm sulfur content fuel according to NSPS IIII. Manufacture dates for
the engines at this site were not included with the NOI, but regardless of the manufacture date, the
475 hp engine would be required to use 15 ppm sulfur content diesel fuel. The 174 hp engine may
or may not be required to use 15 ppm sulfur content diesel fuel, depending on the manufacture date;
however, to satisfy BACT, the 15 ppm sulfur content diesel fuel will be required for the 174 hp
engine. [Last updated May 30, 2024]

3. 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;

Engineer Review N114120003: Geneva Rock Products- Cove Pit
June 25, 2024
Page 12
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 source is not a major source nor a Title IV source; however, the facility is subject to 40 CFR 60
NSPS Subpart IIII, and 40 CFR 63 MACT Subpart ZZZZ regulations. NSPS Subpart IIII, and
MACT Subpart ZZZZ exempt sources from the obligation to obtain a permit under 40 CFR part 70
(Title V permit) if the source is not otherwise required by law to obtain a permit, therefore, the
source is not a Title V source due to 40 CFR 60 NSPS Subpart IIII and 40 CFR 63 MACT Subpart
ZZZZ. However, the facility is also subject to 40 CFR 60 NSPS Subpart OOO, which does not
exempt sources from the obligation to obtain a permit under 40 CFR part 70 (Title V permit).
Therefore, Title V does apply to this facility. [Last updated May 30, 2024]

Hi Katie,
I have completed the compliance review for this one. See attached for my comments as well as some supporting
documentation for my comments.
This might be kind of a tricky one since they haven't had any equipment in operation here since 2009.
Thanks,

Chad,
I'm not quite sure how to include your comment into the permit since I can't add any new conditions or requirements for
the source in a 10-Year Review. I can notify the source of that when I send them the ER.
I also noticed that I sent the wrong version of the Draft ER. Here is the correct version. The main changes are with
spacing issues.
Cheers,
Katie

Hi Katie,
Thanks. Yes, it would be great if the source is notified of the equipment issues. I know there isn't much you can do if they
opt to keep an AO with equipment that no longer exists but we can find them out of compliance and cite them if they bring
this equipment back without letting us know.

Are there any other changes I should make to the ER before I send it to Alan for review and then to the source?
