Chevron Marketing was in compliance during this reporting period. No
further enforcement actions should be taken.

Chevron Marketing’s NSPS monitoring system meets the performance
standards of 40 CFR 60, Appendix B Performance Specifications.

HIGH PRIORITY

Mr Leishman,
Enclosed is a copy of the fourth quarter 2023 Excess Emissions Report for the Chevron Salt
Lake City Marketing Terminal. Electronic and editable copies of the UDEQ format EER will
be submitted to you via email at [e-mail]. Please note that due to the use of
methane subtracting analyzers (CEMs) at the terminal, the term VOC used in the report is
referring to non-methane hydrocarbon (NMHC) parameters which were monitored during the
quarter. Both units are IR 8400D methane compensating analyzers.
The serial numbers on the CEMs cabinets are as follows:
Primary VRU (CEM-1) date of installation 5/15/2014 - SN 4303
Backup VRU (CEM-2) date of installation 6/30/2013 - SN 5235
Upon review of data logging software and therefore to the best of my knowledge, all information
contained in the report is accurate and is a complete record of monitoring related events which
occurred during the reporting period.
If you have any questions regarding this report, please contact me at 503.221.7855
Respectfully,
Shane Partain
OE/HES Specialist
