Dear Director
Hill Air Force Base is submitting this notification, pursuant to Conditions II.B.52.d
existing affected boilers and II.B.53.d new affected boilers of the Main Base Title V Operating
Permit (TVOP) 1100007004, which states "the permittee shall submit a notification of alternative
fuel use within 48 hours of the declaration of each period of natural gas curtailment or supply
interruption. [Origin: 40 CFR 63 Subpart DDDDD] [40 CFR 63.7545(f)]"
On the morning of 28 October 2023 starting at 8:25 am a defective valve resulted in a
supply interruption and firing of multiple boilers on DS2 Diesel Fuel Grade 2-D. The valve was
fixed on the same day and firing on natural gas resumed.
The alternative fuel, DS2 Diesel Fuel Grade 2-D, complies with the specifications under
the definition of distillate oil in 40 CFR 60.41c and is Defense Logistics Agency-Energy
contracted fuel compliant with MIL-STD-3004B 'DoD Standard Practice-Quality Assurance
Surveillance for Fuels, Lubricants and Related Products' for National Stock Number 9140-01-
524-0139.
If you have any questions or would like to discuss this issue further, my point of contact
is Dr. Erik Dettenmaier 75 CEG/CEIEA, at [phone] or [e-mail].
Sincerely
