PERMIT HISTORY When issued, the approval order shall supersede (if a modification) or will be based on the
following documents: Supersedes AO DAQE-AN0143160001-11 dated January 31, 2011
REVIEWER COMMENTS
1. Comment regarding 10 Year Review:
The AO site contact, formatting, and language of AO DAQE-AN0143160001-11, issued January 31, 2011, have been updated. Ames Construction has indicated that there are no changes in equipment or operations.
Per a DAQ Compliance Inspection conducted on June 1, 2020 (see DAQC-915-20, dated June 24,
2020), Equipment ID#s II.A.5 and II.A.6 of the 2011 AO have been removed from site as the facility now operates on utility power. Ames Construction has elected to keep the engines on the updated AO.
The crushers visible emission limit was changed from 15% opacity to 12% opacity per R307-312-4.
The screen and conveyor transfer points visible emission limits were each changed from 10% opacity to 7% opacity per R307-312-4. The 2011 AO did not specify PTEs for CO2e or HAPs. It is assumed the CO2e and HAPs emissions are primarily released from combustion units on site (i.e., the two engine generators). Per Condition II.B.4.a of the 2011 AO, the 725 kW (972 hp) generator is permitted to operate up to 2,630 hours annually while the 60 kW (81 hp) generator is permitted to operate up to 720 hours annually. Therefore, the CO2e and HAPs emissions from each engine were estimated using the applicable hours of operation and emission factors in AP-42, Chapter 3.3, Gasoline and Diesel Industrial Engines (for the 60 kW (81 hp) engine) and in AP-42, Chapter 3.4, Large Stationary Diesel And All Stationary Dual-fuel Engines (for the 725 kW (972 hp) engine.
The site-wide emission estimates should be updated if the source applies for a modification in the future. [Last updated January 14, 2025] 2. Comment regarding Federal Subpart Applicability: NSPS Subpart OOO The Lake Point Limestone Quarry is subject to 40 CFR 60, Subpart OOO (Standards of Performance for Nonmetallic Mineral Processing Plants). The provisions of Subpart OOO applies to each crusher, screening operation, and belt conveyor in fixed or portable nonmetallic mineral processing plants manufactured after August 31 1983. The equipment in this AO is used to process nonmetallic minerals according to 40 CFR 60.671; therefore, NSPS Subpart OOO applies to this source.
NSPS Subpart IIII All stationary engines on site are subject to 40 CFR Part 60, Subpart IIII (Standards of Performance or Stationary Compression Ignition Internal Combustion Engines). 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. The provisions of NSPS Subpart IIII applies to the two (2) diesel-fueled generator engines. Both engines not designated as nonroad and not exempt are affected sources under this regulation.

Engineer Review N143160002: Ames Construction Company- Limestone Quarry February 6, 2025 Page 12
MACT Subpart ZZZZ All stationary engines on site are subject to 40 CFR Part 63, Subpart ZZZZ National Emissions Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines). The provisions of MACT Subpart ZZZZ apply as the stationary reciprocating internal combustion engines (RICE) are at an area source of HAP emissions and are applicable to the two (2) diesel-fired, emergency engines. All engines not designated as nonroad and not exempt are affected sources
under this regulation.
The stationary engines on site that are subject to MACT Subpart ZZZZ must meet the requirements of Subpart IIII. No further requirements apply to these engines under MACT Subpart ZZZZ. [Last updated December 16, 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; 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 major source and is not a Title IV source. The facility is not subject to 40 CFR 61 (NESHAP) regulations. This facility is subject to 40 CFR 60 (NSPS) Subparts A, OOO, and IIII and 40 CFR 63 (MACT) Subparts A and ZZZZ. NSPS Subparts OOO does not specifically exempt the facility from the obligation to obtain a Title V permit; therefore, Title V applies to this facility as an area source. There is no requirement for this source to apply for an initial Title V operating permit under current UDAQ and EPA rules. The source will be charged applicable Title V fees and Title V funds may be
used for inventory and compliance inspections of this source. [Last updated December 16, 2024]

PERMIT HISTORY

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

Supersedes AO DAQE-AN0143160001-11 dated January 31, 2011

REVIEWER COMMENTS

1. Comment regarding 10 Year Review:
The AO site contact, formatting, and language of AO DAQE-AN0143160001-11, issued January 31,
2011, have been updated. Ames Construction has indicated that there are no changes in equipment or
operations.

Per a DAQ Compliance Inspection conducted on June 1, 2020 (see DAQC-915-20, dated June 24,
2020), Equipment ID#s II.A.5 and II.A.6 of the 2011 AO have been removed from site as the facility
now operates on utility power. Ames Construction has elected to keep the engines on the updated
AO.

The crushers visible emission limit was changed from 15% opacity to 12% opacity per R307-312-4.
The screen and conveyor transfer points visible emission limits were each changed from 10%
opacity to 7% opacity per R307-312-4.

The 2011 AO did not specify PTEs for CO2e or HAPs. It is assumed the CO2e and HAPs emissions
are primarily released from combustion units on site (i.e., the two engine generators). Per Condition
II.B.4.a of the 2011 AO, the 725 kW (972 hp) generator is permitted to operate up to 2,630 hours
annually while the 60 kW (81 hp) generator is permitted to operate up to 720 hours annually.
Therefore, the CO2e and HAPs emissions from each engine were estimated using the applicable
hours of operation and emission factors in AP-42, Chapter 3.3, Gasoline and Diesel Industrial
Engines (for the 60 kW (81 hp) engine) and in AP-42, Chapter 3.4, Large Stationary Diesel And All
Stationary Dual-fuel Engines (for the 725 kW (972 hp) engine.

The site-wide emission estimates should be updated if the source applies for a modification in the
future. [Last updated January 14, 2025]

2. Comment regarding Federal Subpart Applicability:
NSPS Subpart OOO
The Lake Point Limestone Quarry is subject to 40 CFR 60, Subpart OOO (Standards of Performance
for Nonmetallic Mineral Processing Plants). The provisions of Subpart OOO applies to each crusher,
screening operation, and belt conveyor in fixed or portable nonmetallic mineral processing plants
manufactured after August 31 1983. The equipment in this AO is used to process nonmetallic
minerals according to 40 CFR 60.671; therefore, NSPS Subpart OOO applies to this source.

NSPS Subpart IIII
All stationary engines on site are subject to 40 CFR Part 60, Subpart IIII (Standards of Performance
or Stationary Compression Ignition Internal Combustion Engines). 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. The provisions of NSPS Subpart IIII
applies to the two (2) diesel-fueled generator engines. Both engines not designated as nonroad and
not exempt are affected sources under this regulation.

Engineer Review N143160002: Ames Construction Company- Limestone Quarry
February 6, 2025
Page 12

MACT Subpart ZZZZ
All stationary engines on site are subject to 40 CFR Part 63, Subpart ZZZZ National Emissions
Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines).
The provisions of MACT Subpart ZZZZ apply as the stationary reciprocating internal combustion
engines (RICE) are at an area source of HAP emissions and are applicable to the two (2) diesel-fired,
emergency engines. All engines not designated as nonroad and not exempt are affected sources
under this regulation.

The stationary engines on site that are subject to MACT Subpart ZZZZ must meet the requirements
of Subpart IIII. No further requirements apply to these engines under MACT Subpart ZZZZ. [Last
updated December 16, 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;
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 major source and is not a Title IV source. The facility is not subject to 40 CFR
61 (NESHAP) regulations. This facility is subject to 40 CFR 60 (NSPS) Subparts A, OOO, and IIII
and 40 CFR 63 (MACT) Subparts A and ZZZZ. NSPS Subparts OOO does not specifically exempt
the facility from the obligation to obtain a Title V permit; therefore, Title V applies to this facility as
an area source.

There is no requirement for this source to apply for an initial Title V operating permit under current
UDAQ and EPA rules. The source will be charged applicable Title V fees and Title V funds may be
used for inventory and compliance inspections of this source. [Last updated December 16, 2024]

Good morning Christine,

There is no change on the layout/operations. I’m sure the equipment is outdated but would be replaced in kind. I know the site has line
power so we don’t use the large gen set. Really we should update this permit as I know it would allow us more production since we don’t
have the engine emissions to worry about. How does this work?

Thanks,

Chris Ennes

Hello Chris,
Thank you for confirming that.
Right now, Ames Construction has 1 of 2 options.
1 - I can proceed with updating the Approval Order as-is. This would be an internal DAQ action and would not result in any fees.
2 - If you are wanting to alter the Approval Order such that any limits are increased, then this action would be considered a modification.
For a modification, a Notice of Intent (NOI) first needs to be submitted to the DAQ under UAC Rule R307-401.

A break down of the necessary steps in submitting the NOI can be found at https://deq.utah.gov/air-quality/new-source-review-permitting-
resources-air-quality

Step 1 is arranging a Pre-NOI meeting to go over the process.

Step 2 is developing the NOI. The necessary forms can be found at https://deq.utah.gov/air-quality/permitting-forms-air-quality

At minimum, you will have to complete the applicable Forms #1 - #5 under "New Source Review" in addition to the applicable "Process-
Specific Forms";
Please let me know how you would like to proceed. I would be happy to set up a virtual meeting if you would like to discuss this further.
Thank you,
Christine

Hello Chris,

Thank you for confirming that.

Right now, Ames Construction has 1 of 2 options.

1 - I can proceed with updating the Approval Order as-is. This would be an internal DAQ action and would not result in any fees.

2 - If you are wanting to alter the Approval Order such that any limits are increased, then this action would be considered a modification.
For a modification, a Notice of Intent (NOI) first needs to be submitted to the DAQ under UAC Rule R307-401.

A break down of the necessary steps in submitting the NOI can be found at https://deq.utah.gov/air-quality/new-source-review-permitting-
resources-air-quality

Step 1 is arranging a Pre-NOI meeting to go over the process.

Step 2 is developing the NOI. The necessary forms can be found at https://deq.utah.gov/air-quality/permitting-forms-air-quality

At minimum, you will have to complete the applicable Forms #1 - #5 under "New Source Review" in addition to the applicable "Process-
Specific Forms";

Please let me know how you would like to proceed. I would be happy to set up a virtual meeting if you would like to discuss this further.

Thank you,
Christine

Good morning Christine,

There is no change on the layout/operations. I’m sure the equipment is outdated but would be replaced in kind. I know the site has line
power so we don’t use the large gen set. Really we should update this permit as I know it would allow us more production since we don’t
have the engine emissions to worry about. How does this work?

Thanks,

Chris Ennes

Good Morning Chris,
Thank you for taking my phone call this morning. As I mentioned, I have come across Approval Order (AO) DAQE-AN0143160001-11,
dated January 31, 2011 - attached - for the Ames Construction Company Lake Point LimeStone Quarry located at Pelican Point, west
side of Utah Lake on Redwood Road.
The Utah Division of Air Quality (DAQ) is going through old AO's to update language and formatting. This action is being conducted by
the DAQ. Ames Construction Company will not have to pay any review fees.
Can you please advise if all the equipment and operations listed on the AO are still accurate?
Thank you,
Christine

Good Morning,
I hope you each had a great weekend.
I have some questions as I update the Approval Order. Please advise at your earliest convenience.
1. The most recent compliance inspection indicates that Items II.A.5 (G-1) and II.A.6 (G-2) have been removed as the site is on utility
power. Does the DAQ have you permission to remove these and all applicable generator conditions from the updated AO?
2. Is Ames Construction interested in re-evaluating its emissions to see if it qualifies to be regulated as an exempted small source?
If a source emits below a certain threshold, they are considered a "small stationary source" under Utah Administrative Code Rule R307-
401-9.
A "small stationary source" is exempt from the requirement to obtain an approval order in Sections R307-401-5 through R307-401-8 if the
following conditions are met.
(a) its actual emissions are less than 5 tons per year per air pollutant of any of the following air pollutants: sulfur dioxide, carbon monoxide,
nitrogen oxides, PM10, ozone, or volatile organic compounds;
(b) its actual emissions are less than 500 pounds per year of any hazardous air pollutant and less than 2000 pounds per year of any
combination of hazardous air pollutants;
(c) its actual emissions are less than 500 pounds per year of any air pollutant not listed in (a) or (b) above and less than 2000 pounds per
year of any combination of air pollutants not listed in (a) or (b) above.
If the above is still true for the Ames Construction facility, then an Approval Order is not required. All I would need at this point is verification
that this is the case (via inventory, emission estimates, etc.), and the DAQ could revoke the Approval Order. The benefit of this is that Ames
would not be subject to the annual New Source Review fee. However, if you expect production to increase in the near future such that
emissions increase, this might not be in your best interest.
This is not a requirement. If you prefer, I can still proceed with updating the Approval Order with the current emission estimates.
Thank you,
Christine

This is valuable information on the process. We will be sure to file for future use.

For now, Ames does not intend to modify. Please proceed with UDAQ’s required administrative changes.

Also update the contact to Olivia Cramm. Same main office phone number.
