Comment regarding NSPS and MACT Applicability: NSPS 40 CFR 60 Subpart GG applies to stationary gas turbines with a heat input at a peak input load above 10 MMBtu/hr. The proposed turbines are rated at less than 1 MMBtu/hr each. This subpart does not apply. Subpart IIII applies to owners and operators of stationary CI ICE that commence construction after July 11, 2005, where the stationary CI ICE are manufactured after April 1, 2006. The stationary engines at this source were manufactured after April 1, 2006; therefore, NSPS Subpart IIII applies to this AO for the stationary diesel-fired engine. Subpart IIII requires engines to meet the emission limits as listed in 40 CFR 60.4204 use diesel fuel in compliance with 40 CFR 80.510, comply with the monitoring requirements of 40 CFR 60.4209, and meet the compliance requirements in 60.4211 Subpart KKKK applies to stationary combustion turbines that commenced construction, modification or reconstruction after February 18, 2005 with a heat input at or greater than 10 MMBtu/hr. The proposed turbines are rated at less than 1 MMBtu/hr each. This subpart does not apply. MACT 40 CFR 63 Subpart JJJJJJ applies to industrial, commercial, or institutional boilers located at an area source of HAP emissions. The on-site boilers are institutional boilers and 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. 40 CFR 63.11195 exempts gas-fired boilers from the applicability and requirements of MACT Subpart JJJJJJ as long as operations using diesel fuel do not exceed 48 hrs; therefore, MACT Subpart JJJJJJ does not apply to the boilers on site. Subpart ZZZZ applies to owners and operators of stationary RICE at a major or area source of HAP emissions. This source will have stationary RICE at an area source of HAP emissions; therefore, MACT Subpart ZZZZ will apply to the stationary engines at this source. Compliance with MACT Subpart ZZZZ is meeting the requirements of NSPS Subpart IIII. [Last updated February 1, 2024] Engineer Review N122790003: Salt Lake Community College- Jordan Campus March 5, 2024 Page 9 2. Comment regarding Title V Applicability: Title V of the 1990 Clean Air Act (Title V) applies to the following: 1. Any major source 2. Any source subject to a standard, limitation, or other requirement under Section 111 of the Act, Standards of Performance for New Stationary Sources; 3. Any source subject to a standard or other requirements under Section 112 of the Act, Hazardous Air Pollutants. 4. Any Title IV affected source. This operation is not a major source and is not a Title IV source. SLCC is subject to NSPS Subpart Dc but is not subject to any numerical emission limit; the source is also subject to NSPS Subpart IIII and MACT Subpart ZZZZ requirements. However, these standards explicitly exempt the sources from the obligation to obtain a Title V permit, provided the sources are not required to obtain a Title V permit for other reasons. Therefore, this facility is not subject to Title V requirements.
