Subject: Review of stack test reports received November 20, 2024
On November 20, 2024, the Utah Division of Air Quality (DAQ) received a stack test report for emissions
testing of the Crusoe Energy Systems – Duchesne Data Center Power Plant’s, Waukesha 2,500 hp Generator
Engine Units 1358, 1361, 1363, 1364, and 1365, located 1 mile northeast of Upalco, Duchesne County, Utah.
Testing was performed October 21-24, 2024, to determine compliance with AO Condition II.B.2.a, II.B.3.b,
II.B.3.c, II.B.3.d, and 40 CFR 60, Subpart JJJJ for NOX, CO, and VOC emissions. The DAQ calculated
results are:

DEVIATIONS: No deviations were noted.

CONCLUSION: The stack test reports for the listed engines appear to be acceptable. Subpart JJJJ
allows a source to use either the g/BHP-Hr emission limit or the ppmdv@15%
oxygen emission limit to determine compliance. The source has provided results
for both limits. The permit specifies a lb/hr limit (not found Subpart JJJJ) and a
more stringent g/BHP-Hr limit so only the permit specified limits are entered for
lb/hr and g/BHP-Hr.

RECOMMENDATION: GE Engines 1358, 1361, 1363, 1364, and 1365 should be considered to have been
in compliance with the NOx, CO, and VOC applicable emissions limits at the time
of testing.

HPV: No.
