Equipment on site consists of boilers, emergency generator engines, and an underground storage tank. Emissions are associated with the combustion of natural gas and ultra-low sulfur diesel (ULSD) fuels. NSR Classification Administrative Amendment Source Classification Located in Salt Lake City UT PM2.5 NAA, Salt Lake County SO2 NAA Salt Lake County Airs Source Size: B Applicable Federal Standards NSPS (Part 60), A: General Provisions NSPS (Part 60), IIII: Standards of Performance for Stationary Compression Ignition Internal Combustion Engines MACT (Part 63), A: General Provisions MACT (Part 63), ZZZZ: National Emissions Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines Title V (Part 70) Area Source DAQE-AN117510005-24 Page 4 Project Description SLCC has proposed the replacement of two (2) dual fuel boilers, listed as II.A.2, with two (2) new dual fuel boilers with lower ratings. The replacement of these boilers will not increase emissions; therefore, the replacement is a Reduction in Air Pollutants under R307-401-12.
