Air Quality Permitting
The permitting branches in the Bureau of Air Pollution Control issues air quality operating permits to stationary and temporary mobile sources that emit regulated pollutants to ensure that these emissions do not harm public health or cause significant deterioration in areas that presently have clean air. This is achieved by stipulating specific permit conditions designed to limit the amount of pollutants that sources may emit into the air as a regular part of their business processes.
Any process/activity that is an emission source requires an air quality permit. Nevada Revised Statute (NRS) 445B.155 defines an emission source as "any property, real or personal, which directly emits or may emit any air contaminant." NRS 445B.110 defines an "air contaminant" as "any substance discharged into the atmosphere except water vapor and droplets." A permit will not be required if your activities, pieces of equipment or storage containers will not cause emissions other than steam or water particles.
The following thresholds are a guide to the various air quality permit types:
• Class 1 - Typically for facilities that emit more than 100 tons per year for any one regulated pollutant or emit more than 25 tons per year total HAP or emit more than 10 tons per year of any one HAP or is a PSD source or major MACT source.
• Class 2 - Typically for facilities that emit less than 100 tons per year for any one regulated pollutant and emit less than 25 tons per year total HAP and emit less than 10 tons per year of any one HAP.
• Class 3 - Typically for facilities that emit 5 tons per year or less in total of regulated air pollutants and emit less than one-half ton of lead per year, and must not have any emission units subject to Federal Emission Standards (ie: NSPS, NESHAPS, MACT, etc.)
• Class 4 - Typically for a single area source that emits less than 10 tons per year for any one HAP and less than 25 tons of a combination of HAPs annually and not subject to Class 1, 2, or 3 permitting.
• SAD - Surface Area Disturbance of >5 acres.
• General / COLA - Temporary portable equipment for road and highway construction at a location < 12 months.
