Mobile, Smoke and Area Sources Branch


The Mobile, Smoke, and Area Sources Branch is responsible for implementing programs that enhance air quality and limit emissions from several diverse sources.

Mobile Sources

Mobile sources are primarily on-road motorized vehicles including cars, trucks, buses, and motorcycles, but also include non-road equipment such as construction and recreational equipment. Emissions from mobile sources are controlled through the following programs:

Smoke Management

Smoke generated through prescribed burning operations and fire training is a concern to air quality planners. The purpose of the Nevada Smoke Management Program is to coordinate and facilitate the statewide management of prescribed outdoor burning in the state of Nevada. Under the program, land management agencies and other organizations planning prescribed burns must obtain a permit from the NDEP and conduct their operations in manner that mitigates smoke impacts. This includes igniting burns only under favorable fuel moisture and meteorological conditions; using trained crews; monitoring for potential smoke impacts; and considering alternatives to burning where appropriate.

Area Sources

The 1990 Clean Air Act (CAA) Amendments established a new and fairly complex program to regulate emissions of 188 hazardous air pollutants (HAPS) from particular industrial sources and small businesses called area sources. The Area Sources program issues Class IV Air Quality Operating Permits to affected businesses and industries that require the permit holder to follow federal regulations intended to control HAP emissions. A few examples of the businesses and their corresponding HAPs that are regulated under the Area Sources program are: gasoline dispensing and bulk storage facilities for benzene; dry cleaning establishments for perchloroethylene; certain metal processing and fabrication facilities for hazardous metals; and several other area sources.
