PROCESS DESCRIPTION: Staker & Parson Companies operates a pit in South Weber for
concrete production. Emissions come from several different
sources at the site. The pit has several feeders, crushers, and
screens, that produce particulate emissions. The site also has
wash plants. The site is currently permitted to produce 1,500,000
tons of aggregate. A concrete plant operating under the company
name of Jack B. Parson has been permitted on this AO. The plant
is situated on the east side of the disturbed area and is overseen
by a separate plant manager. The plant includes cement silos and
a water heater. The current production limit is 225,000 cubic
yards of concrete. Staker & Parson Companies employs several
pollution control techniques. Baghouses and bin vents to reduce
PM emissions. Low NOx burners reduce NOx from a water
heater that has been converted to natural gas.

-14.4063 a D9 – 18 hrs.
-14.4028 a D8 – 148.9
-14.4004 a D8 – 50 hrs.
I am waiting on a monthly breakdown of these hours but let me know if this works.
Mag Chloride applications do occur at least twice per year. I can try to obtain invoices for those if you need
them.

The duplicate reporting on production would be for a temporary crusher being in the pit along with the
crusher that stays in the pit.

Let me know if you have any questions.

Hello - I am behind in reviewing some of my inspection records - with regards to the South Weber records, the submitted
dozer hours list the months of June 1, 2022 through July 1, 2023. Do you have the 12-month rolling totals for the 2023
through 2024 time period? With regards to chemical applications (II.B.6.a.1), previous inspections have reported that
mag chloride applications tend to happen twice a year. Is this still correct? Also, with regards to the reported aggregate
totals, I noticed that the months of July, August and September of 2023 were reported twice with different totals. I take it
that this is due to reporting the aggregate totals for the temporary crushing project that occurred with the TRP DAQC-659-
23 dated July 6, 2023? Thanks!

Hello, I'm not sure who the current contact is who replaced Christian Boudreau for this type of document retrieval.
Please forward this on, or let me know the correct email I should use for inspection related record requests.

Earlier today, I performed a routine site inspection for the South Weber Pit, located at 2585 East South Weber Drive. In
order to complete the inspection I will need the following records to demonstrate compliance with the AO
AN109280010-19:

As per Condition II.B.2.a - the 12-month rolling aggregate production totals for the time period of July 2023 through
June 2024.
II.B.3.a - the 12-month rolling concrete production totals for the same time period.
II.B.4.a - the 12-month rolling natural gas consumption totals for the hot water heater.
II.B.5.a - the 12-month bulldozer hours of operation.
II.B.6.a.1 - recent watering/chemical application records.
NSPS OOO - recent monthly spray nozzle records.

Let me know if you have any questions or comments. I've attached the current AO for reference. Thanks
