SOURCE INFORMATION
General Description
Mountain View Mushrooms (MVM)is a producer and wholesaler of fresh mushrooms located in
Fillmore, Millard County. MVM starts the process outdoors by creating compost for the spores to grow
on. When the compost is ready, it is added to growing trays and taken inside to a pasteurization room to
eliminate undesirable bacteria. Once the trays are prepared, the mushroom spawn is mixed with the
compost, and the growing tray is placed in another room for several weeks to allow the spawn to grow.
After spawning, the growing trays are placed in a growing room, and mushrooms are harvested several
weeks later. MVM harvests mushrooms every day to ship them to a variety of places in the Intermountain
West region.

Project Description
MVM is permitted to operate one (1) primary natural gas-fired, 600 hp boiler and one (1) standby
dual-fuel, 300 hp boiler. MVM is requesting to operate the 300 hp (12 MMBtu/hr) standby dual-fuel
boiler as the primary boiler and replace the primary 600 hp boiler with a standby, dual-fuel, 100 hp (4.18
MMBtu/hr) boiler. Both boilers operate with low-NOx burners. These equipment changes result in an
actual decrease of all criteria pollutant and HAP emissions.

Therefore, this project meets the requirements of UAC R307-401-12 Reduction in Air Pollutants and does
not require a public comment period.
