SUMMARY
This is a c lass II, synthetic minor permit issued to Guardian Fiberglass, Inc. located in Kingman, Arizona

. Guardian Fiberglass manufactures wool fiberglass insulation sheets and shredded wool fiberglass, for use in commercial and residential buildings.
This faci lity operates an electric melter and a natural gas fired, 5.83 MMBtu/hr forehearth oven to melt the raw material before sending it through fiber forming units comprised of 8 identical 9.6 MMBtu/hr process heaters. In addition, Guardian Fiberglass operates an 18 MMBtu/hr oven to be used for curing of the resinated fiberglass. There are three stacks at the facility; EP1, associated with the Forming and Collection Process, EP2, associated with the Melting and Refining Process, and EP3, associated with Curing and Cooling Process. The emissions, from the stacks, are controlled by one thermal oxidizer on EP3, two dust collectors on EP2, one wet scrubber, three water sprays and dropout boxes on EP1. In addition, there is a baghouse installed on the blow wool ba ggers area. Guardian fiberglass also operates a continuous monitoring system on EP1 to monitor emissions of carbon monoxide. Maximum production capacity of the unit is 8000 pounds per hour (lb/hr) o f which 7000 pounds per hour may be allocated to resinat ed fiberglass production. Operating 8760 hours per year at maximum production rate of 8000 pounds per hour, Guardian Fiberglass emits less than 100 tons per year of all criteria pollutants.
