Stationary
Sources
A stationary source is any building, structure, facility, or installation subject to regulation which emits or may emit any air pollution. These sources include power generating plants, landfills, petroleum facilities, chemical plants, mining operations, cement and glass manufacturing companies, and many other heavy industrial sources. Pollutants are emitted into the air from these plants through fossil fuel combustion, chemical processes, and the grinding or pulverizing of metals for cement, fertilizers, etc. These processes emit a number of harmful contaminants into the air including sulfur dioxide, nitrogen oxides, carbon dioxide, synthetic compounds, and particulate matter. PDEQ regulates these sources to ensure Pima county meets and maintains the national air quality standards.
