Dear Mr. Sessions:

Re: Request for Evaluation of Compliance with Rule R307-401-9, UAC: Small Source Exemption
Project Fee Code: N162290001

On August 2, 2024, the Division of Air Quality (DAQ) received your request for a small source
exemption for the M&S Concrete Solutions - Layton Concrete Recycling Facility. The source is located
approximately 0.15 miles north of the intersection of West Gentile Street and Sugar Street at Universal
Transverse Mercator (UTM) coordinates 417,057 meters Easting and 4,546,146 meters Northing (Datum
NAD 83, Zone 12), Layton, Davis County. The DAQ has determined the small source exemption applies
to the source as long as the equipment and associated processes operate as specified in the registration
request. According to your application, the facility will not exceed 1,600 hours of operation annually. Per
the application, M&S Concrete Solutions will not produce more than 96,000 tons of recycled concrete
aggregate annually.

The small source exemption does not exempt a source from complying with other applicable federal,
state, and local and the current Utah Administrative Code. Based on the emissions that you submitted to
the DAQ with your registration request, the M&S Concrete Solutions - Layton Concrete Recycling
Facility is not required to obtain an approval order under R307-401. If you change your operation such
that there is an increase in emissions, we recommend that you notify us, as an approval order may be
required.

As authorized by the Utah Legislature, the fee for issuing this small source exemption is a one-time filing
fee in addition to the actual time spent by the review engineer and all other staff on the project. Payment
should be sent to DAQ upon receipt of the invoice.

Hi Mike,
Thanks for submitting your Small Source Exemption (SSE) application. To continue processing your application I'll need more information about your emission
calculations.
Your calculations must include all emission units present at your facility These likely include haul roads, storage piles, any aggregate processing (ie crushing) and
material handling that takes place, the concrete batch plant and any generators that might be present. The calculations should be submitted as spreadsheets rather
than PDFs or images.
DAQ spreadsheets that will guide you through these calculations can be found here:
https://deq.utah.gov/air-quality/emissions-calculations-spreadsheets
If your facility includes any emission units that are not included in the DAQ spreadsheets please refer to AP-42 for emission factors.
I'll continue processing your application after your completed Excel spreadsheets are returned to me along with any relevant equipment spec. sheets.
Please feel free to reach out to me with any questions you have. Hope you had a good weekend!
Lucia

Ok great!
I'll still need you to provide the spreadsheet you used to calculate storage pile emissions along with calculations for emissions from any haul roads,
aggregate processing, material handling and additional emission units that might be at the facility.
Let me know if you have any questions,
Lucia

Thanks for all your submissions Mike. To draft your SSE letter I need to confirm some contact information.
Would you like your name and contact information listed on the letter? If not, who should I list and what is their contact information?
Would you like to list a separate billing contact? If so, can you provide their email and phone?
Lastly, can you confirm your billing address?
Thanks so much for your time,

At the yard, we will receive used concrete and washout concrete/water. The used concrete and washout concrete will be stored in piles until we have sufficient to
rent a mobile concrete crusher. We will crush for about 2 week every 3-4 months. The crushed concrete will be stored in piles and sold to contractors and the
public. The washout water was tested and approved by the local sewer district to be put into the sewer (Lab testing was done and approved). We will also receive
gravel, road base and topsoil to be resold to contractors and the public. They will also be stored in piles until sold.
