Project Description
Weir has requested an administrative amendment to AO DAQE-AN105550006-18, to reduce VOC and
HAPs associated with the removal of the Packer Paint Booth. The Packer Paint Booth was solely
dedicated to the application of the adhesive product Chemlok 252X to metal parts that were produced at
the facility. The removal of the adhesive product and paint booth results in a reduction of 13.11 tons per
year of VOC emissions and a reduction of 12.69 tons per year of combined HAPs (10.58 tons per year of
Xylene and 2.11 tons per year of Ethylbenzene).

The permit change is a reduction in the emissions of volatile organic compounds and hazardous air
pollutants, which qualifies as a "Reduction in Air Pollutants" as per Utah Administrative Code
R304-401-12.

SUMMARY OF EMISSIONS

The emissions listed below are an estimate of the total potential emissions from the source. Some
rounding of emissions is possible.

Criteria Pollutant Change (TPY) Total (TPY)

PERMIT HISTORY When issued, the approval order shall supersede (if a modification) or will be based on the
following documents: Replaces AN105550006-18 dated June 11, 2018
Is Derived From Notice of Intent dated May 28, 2024 Incorporates Additional Information dated September 19, 2024
REVIEWER COMMENTS 1. Comment regarding Emission Estimates: The plantwide VOC emissions are calculated on a mass balance of VOC containing material consumed at the Weir facility each month. [Last updated July 2, 2024] 2. Comment regarding HAP Major source: Weir's, Salt Lake Facility is classified as a HAP major source with the PTE emissions of 42.29 TPY of combined HAPs. The HAPs are being reduced from 54.98 TPY combined. The HAP emissions are not being separated out in this permit change. [Last updated July 2, 2024] 3. Comment regarding VOC Emissions Reduction:
UDAQ, NSR reviewed the last three years of emissions inventories (actual emissions) to determine if Weir, Salt Lake Facility could reduce VOC PTE emissions below the new major source threshold classification (50 TPY of VOC). The average actual VOC emissions that were submitted to UDAQ
emissions inventory for the years 2021, 2022 and 2023 is 28.39 TPY. This value validates that the Salt Lake Facility can reduce the PTE to 48.15 TPY with the removal of the paint booth/dust collector and adjust current production and still remain below 50 TPY of VOC emissions. [Last
updated July 2, 2024] 4. Comment regarding Permit Analysis: This project is reducing emissions of VOC and HAP PTE emissions but does not account for any other emissions changes. This permit change is being conducted as an administrative amendment which does not require a public comment per UAC R307-401-5. This project is being conducted to reduce emissions below major source classification (50 TPY). [Last updated July 2, 2024] 5. Comment regarding Ozone SIP: Weir, Salt Lake Facility has reviewed current operations with the paint booth removal and the adhesive product operations removed at the Salt Lake Facility to determine if the sitewide VOC PTE emissions can be reduced without impacting production levels or permit conditions. The reduction in site wide VOC emission will classify Salt Lake Facility as a synthetic minor (SM) source (less than 50 TPY VOC). Weir, Salt Lake Facility will be classified as a SM classification and will not be
included in the Moderate Area Ozone State Implementation Plan Development. [Last updated July 2, 2024]
6. Comment regarding Title V Alignment: This permit modification involves aligning AO requirements with the Title V permit requirements. This update keeps both permits consistent with the requirements. 40 CFR 63 Subpart T (National
Emission Standards for Halogenated Solvent Cleaning) was removed to be consistent with the Title V. [Last updated July 2, 2024]

Engineer Review N105550008: Weir Minerals, Inc. November 13, 2024 Page 12

7. Comment regarding Condition Changes: This administrative amendment was conducted to lower site wide VOC PTE emissions below 50 TPY. The only changes to the permit conditions are to the plantwide VOC emissions limit (previous
permit II.B.2.a) lowering the VOC from 60.22 to 47.18 TPY and the removal of the Packer Paint Booth (previous permit II.A.2) and Packer Sandblast Dust Collector (previous permit II.A.4). [Last updated July 2, 2024]
8. Comment regarding Sitewide VOC Limit Discrepancy: The existing AO had a sitewide VOC limit of 60.22 TPY of VOCs but was unclear if the sitewide
limit included VOC emissions from combustion sources. The existing AO has a total PTE VOC emission of 61.19 TPY of VOC emissions. The Title V permit has an aggerated VOC limit of 59.46 TPY of VOC emissions without specifically specifying the exclusion of combustion emissions. The new AO sitewide VOC emission used the aggerated VOC limit from the Title V permit. It was specified in the new AO limit that VOC combustion emissions are excluded from the new sitewide VOC emissions limit. [Last updated July 2, 2024] 9. Comment regarding New Permitting Format: Weir, Salt Lake Facility existing approval order (DAQE-AN10555006-18) was issued on June 6, 2018. The UDAQ permits have changed formats, and this administrative amendment has reformatted the permit, but the conditions have remained the same. [Last updated July 2, 2024]
10. Comment regarding SIP Applicability: Weir, Salt Lake Facility is classified as a major HAP source (greater than 25 TPY of combined
HAPs) with 42.29 TPY of combined HAPs. Weir, Salt Lake Facility is not listed in any Utah SIPs since the only criteria classifying this source as a major source is HAPs. [Last updated July 2, 2024]
11. Comment regarding Additional Information: Weir submitted additional information on September 19, 2024, addressing the emissions rate for the Banbury Baghouse Stack. The emissions rate for the baghouse was 22.51 lb/hr and was updated to 0.54 lb/hr as a result of stack testing and a safety factor. This new emissions rate reduction does not affect the PTE emissions. The previous emissions rate was assumed to be incorrect since all stack tested emissions rates were under 1 lb/hr.

SUBJECT: ADMINISTRATIVE AMENDMENT REQUEST

RE: WEIR MINERALS, INC. (UDAQ Approval Order: DAQE-AN105550006)
3459 South 700 West
Salt Lake City, UT 84119
Dear Mr. Bird:
On behalf of Weir Minerals, Inc. (Weir), RMEC Environmental, Inc. (RMEC) is hereby providing the Utah
Division of Air Quality (UDAQ) with the following request for an administrative amendment of the above-
referenced Approval Order (AO). This request is in accordance with the provisions for a “Reduction in Air
Pollutants” as per Utah Administrative Code R304-401-12. The basis for this request is due to a reduction
in the emissions of volatile organic compound (VOCs) and hazardous air pollutants (HAPs) associated with
the removal of a paint booth.
DESCRIPTION OF MODIFICATION
Background Information
A significant portion of Weir’s emissions of VOCs are associated with application of various coatings and
adhesives in the three (3) paint booths. One of these paint booths, identified in the AO as the “Packer Paint
Booth”, has been removed. With the removal of the Packer Paint Booth, Weir is hereby requesting a
decrease in the VOC and HAP emissions limitations as specified in the current AO.
Calculation of Emission Reductions
The Packer Paint Booth was solely dedicated to the application of the adhesive product Chemlok 252X to
metal parts that were produced at the facility. This process has been discontinued and the Packer Paint
Booth has been removed.
A Graco WPR 5,000 PSI spray gun with a maximum flow rate of 1.63-gallon per hour (GPH) was dedicated
to spraying the Chemlok 252X adhesive in the Packer Paint Booth. Based on past operations of the paint
booth to account for setup, part layout, drying and transfer of parts out of the paint booth, the maximum
potential-to-emit (PTE) calculations for this paint booth would assume no more than 30% active spraying
time during operational hours. This would equate to 7.2 hours of active spray time per 24-hour period.
As demonstrated in the calculation below, the total paint throughput for the Packer Paint Booth would be
4,284 gallons:

UDEQ / Bryce Bird RMEC PJ23E-4681
Page 2 of 3 May 28, 2024

Maximum Paint Throughput:
= (1.63 GPH)(7.2 hours/day)(365 days/year) = 4,284 gallons/year
Table 1, below, provides a summary of changes in emissions in VOCs and HAPs based on the elimination
of the Packer Paint Booth painting operations:

Acute: Vapor harmful; may affect the brain or nervous system causing dizziness, headache or nausea. Possible
irritation of the respiratory system can occur causing a variety of symptoms such as dryness of the throat, tightness of
the chest, and shortness of breath. May cause central nervous system depression characterized by the following
progressive steps: headache, dizziness, staggering gait, confusion, unconsciousness or coma. In elevated-temperature
applications, product may release vapors that may produce cyanosis in the absence of sufficient ventilation or
adequate respiratory protection. The imide in this product is a respiratory hazard. Inhalation of product vapors, fumes
or particulates during heating should be avoided.May be harmful if swallowed. Ingestion is not an expected route of
entry in industrial or commercial uses.
Chronic: May affect the gastrointestinal system. May affect the blood and blood-forming organs. Overexposure to
lead in this product can damage the nervous, urinary, gastrointestinal, blood, blood-forming, and reproductive
systems. Lead and lead compounds have been classified by IARC as probable human carcinogens (Group 2A), and
by NTP as reasonably anticipated human carcinogens. Ethylbenzene has been classified by IARC as a possible
human carcinogen (Group 2B) and reported by NTP to show clear evidence for carcinogenicity in animals. IARC has
designated carbon black as Group 2B - inadequate evidence for carcinogenicity in humans, but sufficient evidence in
experimental animals. In 2006 IARC reaffirmed its 1995 finding that there is "inadequate evidence" from human
health studies to assess whether carbon black causes cancer in humans. Further, epidemiological evidence from well-
conducted investigations has shown no causative link between carbon black exposure and the risk of malignant or

SPECIFIC HAZARDS POSSIBLY ARISING FROM THE CHEMICAL: Flammable liquid and vapor. Keep containers
tightly closed. Isolate from heat, electrical equipment, sparks, open flame, and other sources of ignition. Closed containers
may rupture when exposed to extreme heat. Use water spray to keep fire exposed containers cool. WARNING: Due to the
combustible nature of the dried film of this product and the potential for smoldering or fire, the accumulation and buildup of
the dried film on spray booth walls and floors, spindles, fixtures and other surfaces should be avoided, and any buildup
should be removed. Keep the dried film accumulations away from sparks, friction, impact, high heat (>235 F/>112 C) or
other sources of ignition. These conditions could cause the dried film to ignite very readily and quickly, and the resulting
smoldering or fire may be difficult to extinguish. During removal of accumulation/buildup of this product, take precautions
to avoid heat, friction and impact during the cleaning process. Use paint stripper, brass brush, or plastic scraper for cleaning.
In the event of smoldering or a fire involving the dried product, Cold Fire®** fire suppressing agent is preferred as the
