Comment regarding 10 Year Review: The formatting and language of Approval Order DAQE-800-97, dated August 25, 1997, have been updated. There are no equipment or operational changes at this time. The 1997 AO did not specify a potential-to-emit (PTE) for hazardous air pollutants (HAPs), CO2 equivalent, or PM2.5. The PTE's for HAPs and CO2 equivalent were calculated assuming the following parameters: - 7,500 hours of operation annually of both boilers combined using natural gas - 500 hours of operation annually of both boilers combined using fuel oil - 100 hours of non-emergency use for the diesel-fired emergency engine For a conservative estimate, the PTE of PM2.5 was assumed to be equal to the PTE of PM10 (0.02 tpy). The source was advised that, given the number and size of equipment on site, it might qualify to be regulated as an exempted small source under UAC R307-401-9 and would therefore not require an AO. The source elected to have the AO updated as-is. The PTE's of all criteria and HAPs pollutants should be updated in the future when the source undergoes a modification. Lastly, Condition #13 of the 1997 AO specifies "The sulfur content of any fuel oil or diesel burned shall not exceed 0.5 percent by weight.". Per the Code of Federal Regulations, Title 40, Chapter I, Subchapter U, Part 1090 Subpart D, § 1090.305, the maximum sulfur content of diesel fuel shall not exceed 15 ppm. The AO has been updated accordingly. [Last updated October 21, 2024] 2. Comment regarding Federal Standard Applicability: NSPS Subpart Dc 40 CFR 60 (NSPS) Subpart Dc applies to owners/operators of steam generating unit that has a maximum design heat input capacity of 100 MMBtu/hr or less, but greater than or equal to 10 MMBtu/hr. Steam generating unit means a device that combusts any fuel and produces steam or heats water or heats any heat transfer medium. All of the boilers that the source operates are smaller than 10 MMBtu/hr. Therefore, Subpart Dc does not apply to any boilers at this facility. NSPS Subpart IIII 40 CFR 60 Subpart IIII applies to owners and operators of Stationary Compression-Ignition Internal Combustion Engines (CI ICE) that commence construction after July 11, 2005, where the stationary CI ICE is manufactured after April 1, 2006. The CI ICEs at this site were constructed prior to this date. Therefore, Subpart IIII does not apply to this source. MACT Subpart ZZZZ 40 CFR 63 Subpart ZZZZ (National Emissions Standards for Hazardous Air Pollutants for Engineer Review N115020007: Federal Aviation Administration - Salt Lake International Airport November 15, 2024 Page 9 Stationary Reciprocating Internal Combustion Engines) applies to owners and operators of stationary internal combustion engines (RICE) at an area source of HAP emissions. Therefore, MACT Subpart ZZZZ applies to the emergency engine. MACT Subpart JJJJJJ 40 CFR 63 MACT Subpart JJJJJJ (National Emissions Standards for Hazardous Air Pollutants for Industrial, Commercial, and Institutional Boilers Area Sources) applies to industrial, commercial, or institutional boilers located at an area source of HAP emissions. The boilers on site are considered institutional boilers. Gas-fired boilers are not subject to MACT Subpart JJJJJJ. While the boilers on site use natural gas as primary fuel, they are not considered gas-fired boilers as defined in 40 CFR 63.11237. A gas-fired boiler burns only gaseous fuels during normal operation and burns liquid fuel only during periods of gas curtailment, gas supply interruption, startups, or periodic testing on liquid fuel. The on-site boilers are permitted to operate the boilers using fuel oil as fuel for up to 500 hours, regardless of operational scenario. Therefore, MACT Subpart JJJJJJ does apply to the boilers on site. [Last updated October 21, 2024] 3. Comment regarding Title V Applicability: Title V of the 1990 Clean Air Act (Title V) applies to the following: 1. Any major source; 2.
