Administrative Amendment to AO DAQE-AN148470001-14 for Equipment Modifications and Production Changes Qualifying as Reductions in Air Pollutants under UAC R307-401-12
Project Description Changes to Permit AO DAQE-AN148470001-14: 1. Add one (1) asphalt cement (AC) storage tank to the Talon Cove HMA Plant 2. Reduce annual asphalt production from 500,000 tons per year to 250,000 tons per year, thus
reducing recycled asphalt production from 141,000 to 37,500 tons per year 3. Remove CMI 400 T Drum (company equipment ID #35.320801) listed in Section II.A.2 and replace with a new Maxum Mix Drum (manufacture date 2015) EMISSION IMPACT ANALYSIS
All equipment and throughput changes resulting from this administrative amendment have not increased criteria or hazardous air pollutant (HAP) emissions. Consequently, no modeling is required based on UAC R307-410-4 and UAC R307-410-5. Additionally, this administrative amendment qualifies for a reduction in air pollutants under UAC R307-401-12.

Review of BACT for New/Modified Emission Units 1. BACT review regarding Asphalt Cement (AC) Tank
After identifying all available control technologies for the asphalt cement (AC) tank, including vapor recovery systems, thermal oxidizers, and carbon adsorption systems, and evaluating their technical feasibility, it was determined that all options are technically feasible. However, upon
assessing the control effectiveness and considering the environmental and economic impacts, it was found that vapor recovery systems, thermal oxidizers, and carbon adsorption systems have high initial and operational costs and potential secondary emissions. Given the relatively low volatile organic compound (VOC) emissions from the AC tank, the costs and impacts of implementing these controls outweigh the benefits of minor emission reductions. Therefore, no additional controls are recommended. [Last updated June 10, 2024]

PERMIT HISTORY When issued, the approval order shall supersede (if a modification) or will be based on the
following documents: Replaces AO DAQE-AN148470001-14 dated January 22, 2014
Incorporates NOI dated March 26, 2024 Incorporates Additional Information dated July 26, 2024
REVIEWER COMMENTS 1. Comment regarding Condition Updates: During this administrative amendment, the permit conditions for stack testing, fugitive emissions, and baghouse requirements were updated to align with current permit language. Additionally, the baghouse opacity limit was revised from 20% to 10%. [Last updated August 16, 2024] 2. Comment regarding Production and condition changes: As per UAC R307-401-12, the owner/operator of a source is exempt from having to submit an NOI if "the project does not increase the potential to emit of any air pollutant or cause emissions of any new air pollutant" and "the director is notified of the change and the reduction of air pollutants is made enforceable through an approval order". Granite notified the DAQ of these changes and the
subsequent changes do not cause any increase in any air pollutants or cause any new pollutants to be emitted. Therefore, this project qualifies as a reduction in air pollutants under R307-401-12 and Granite is exempt from having to submit an NOI.
Below is a list of specific changes that were made to this permit: 1. Addition of one (1) asphalt cement (AC) storage tank to the Talon Cove HMA Plant (Equipment List item: II.A.17)
2. Reduced annual asphalt production from 500,000 tons per year to 250,000 tons per year, thus
reducing recycled asphalt production from 141,000 to 37,500 tons per year. (This was updated in condition II.B.1.f) 3. Remove CMI 400 T Drum (company equipment ID #35.320801) listed in Section II.A.2 and replace with a new Maxum Mix Drum (manufacture date 2015) 4. The company mailing address and point of contact information was updated. 5. The emissions reductions were accounted for in the PTE section of the new permit. [Last updated September 9, 2024] 3. Comment regarding NSPS and MACT Applicability :
This source is subject to 40 CFR 60 (NSPS) Subpart I and Subpart OOO.

Re: Talon Cove Hot Mix Asphalt (HMA) Plant (DAQE-AN148470001-14) Permit
Modification.

Dear Mr. Persons,

This letter summarizes the proposed change to the Talon Cove HMA Plant (DAQE-
AN148470001-14) equipment and annual production quantities.

Talons Cove HMA Plant is located in Eagle Mountain City, Utah County. Utah County is a
nonattainment area of the NAAQS of the Clean Air Act for PM10 and PM2.5. Talons Cove is
subject to NSPS part 60 subparts A, I and OOO. It is not subject NESHAP or MACT standards.
It is subject to Title V of the 1990 Clean Air Act and is considered an area source.

Permitted Location:
Talons Cove Hot Mix Asphalt Plant
4288 East Ranches Parkway
Eagle Mountain, UT 84005

UTM Coordinates: 418495 m Easting, 4471934 m Nothing, UTM Zone 12
SIC Code: 2951 (Asphalt Paving Mixtures & Blocks)

Granite proposed changes to permit DAQE-AN148470001-14 are as follows:

1. Addition of one (1) asphalt cement (AC) storage tank to the Talon Cove HMA Plant,
which is currently permitted to have three (3) AC tanks.
2. Reduction of annual asphalt production from 500,000 tons per year to 250,000 tons per
year. Thus, reducing recycled asphalt production from 141,000 to 37,500 tons per year.
3. Remove CMI 400 T Drum (company equipment ID #35.320801) listed in Section II.A.2
and replace with a new Maxum Mix Drum (manufacture date 2015).

Updated emission calculations for criteria pollutants are details in Attachment A and
summarized in Table 1. Table 1 outlines the change to the permit PTE totals. The required
UDAQ forms are provided in Attachment B (Forms 2, 4, and 5).

Table 1. Changes to PTE
Pollutant Current PTE (TPY) New PTE (TPY)1 Changes to PTE (TPY)
NOX 6.5 3.25 -3.25
SO2 0.85 0.43 -0.42
CO 33.18 16.62 -16.56
PM10 - Total 9.68 2.88 -6.8
PM2.5 - Total 1.39 1.39 0
VOC 11.84 5.92 -5.92
CO2e 47,414.22 13,056 -34,355.22
Total HAPS 0.01 0.01 0
Note:
1 See Table A-2 of Appendix A.
