The Air Program 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 implementing and enforcing specific permit conditions designed to limit the amount of pollutants that sources may emit into the air as 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.
• SAD - Surface Area Disturbance of >5 acres.
• General / COLA - Temporary portable equipment for road and highway construction at a location < 12 months.
This feature class includes permits that are active as well as permits that are not active anymore (i.e., terminated). Many facilities (identified by their Facility Identification Number, FIN) may have multiple permits. The permit number for a Change of Location (COLA) permit is the number of the general permit issued to the organization (the same organization can have multiple locations under a single general permit). However, the location is where the specific temporary portable equipment is located.
This feature class includes all permits that are currently active, regardless of when they were issued. However, for those permits that were terminated, this feature class only goes back to permit issued in 2013 for Class1 and Class 2 AQOP, and 2017 for Class 2 Surface Area Disturbance.
A companion feature class for this feature is the AIMS Facilities feature class. This map displays the facilities that the Air Program is currently regulating or were regulated.

Each facility is identified by its Facility Identification Number (FIN) and the following are the definitions for the Source Category
• Major - 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 Hazardous Air Pollutant (HAP) or emit more than 10 tons per year of any one HAP or is a Prevention of Significant Deterioration (PSD) source or major MACT source.
• Minor - 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.
SM-80 – Synthetic Minor facilities. Sources that emit or have the potential to emit at or above 80 percent of the Title V major source threshold. This is a category of minor facilities defined by EPA for compliance and enforcement purposes.
This feature class includes facilities that are operating as well as facilities that are not operating anymore (i.e., permanently closed).
This feature class includes all the facilities that currently operating, regardless of when they started operating. However, for those facilities that were permanently closed, this feature class only goes back to facilities for which the permit was issued in or after 2013 for Class1 and Class 2 AQOP, and in 2017 or after for Class 2 Surface Area Disturbance.
A companion feature class for this feature is the AIMS Permits feature class. This map displays the permits that the Air Program has issued.
This feature class contains the locations of the Discharge Monitoring Report (DMR) monitoring wells. Analytical data for each well can be viewed in the related tables, DMR_Data_Conc and DMR_Data_Quant.
