Subject: Review of Pretest Protocol dated March 12, 2025
On March 14, 2025, DAQ received a protocol for testing of the Hot Mix Asphalt Plant at the Point of the
Mountain Facility in Bluffdale, UT. Testing will be performed on May 6, 2025, to determine compliance
with the emission limits found in conditions II.B.1.c and II.B.3.i in Approval Order
DAQE-AN112340015-24.
PROTOCOL CONDITIONS:
1. RM 1 used to determine sample velocity traverses: OK
2. RM 2 used to determine stack gas velocity and volumetric flow rate: OK
3. RM 3 used to determine dry molecular weight of the gas stream: OK
4. RM 4 used to determine moisture content: OK
5. RM 5 used to determine particulate matter emissions: OK
6. RM 9 used to determine visible emissions opacity: OK
7. RM 202 used to determine condensable particulate matter: OK
DEVIATIONS: None.
CONCLUSION: The protocol appears to be acceptable. Attached is an email
correspondence with Chris Rose confirming that Method 9
opacity readings will be taken for the full 60 minutes of each
run, in order to be compliant with the initial performance testing
requirements of 40 CFR Part 60 Subpart I.
