| Stationary Source | A stationary source is defined as any source of at least one criteria pollutant that remains stationary for more than 12 months at a time. Stationary sources include all point sources and some area sources. |
| Area Source | Most area sources are small sources individually emitting less than ten tons per year. They are smaller sources that do not qualify as point sources under the relevant emissions cutoffs. Area sources encompass more widespread sources that may be abundant but that individually release small amounts of a given pollutant. Examples typically include dry cleaners, residential space heating, auto body painting, and consumer solvent use. |
| Solvent Evaporation | One component of area source emissions include solvent evaporation during the storage or use of solvent products. The major pollutant of concern is volatile organic compounds. These emissions typically results from the use and storage of pesticides, asphalt paving, and consumer products, such as paint and aerosols. |
| Point Source | Emissions form a point source occur at a facility that can be identified by name and location and which emits a sizeable, measurable, quantity (i.e. more than ten tons per year) of at least one criteria pollutant. Point sources are typically large manufacturing or production plants used for industrial and commercial processes. |
| Industrial Processes | The industrial processes category includes emissions from the production, processing, manufacturing and storage of materials used in industrial applications. Examples of these sources include mineral processing, fuel processing, waste disposal, paper, glass, and chemical production, and commercial processes such as food processing and storage. |
| Mobile Sources | A mobile source is defined as any source which emits at least one criteria pollutant that moves form one place at least once in a 12 month period. The Mobile Source Category is a sub-section of the Area Source Category, but is treated separately because of the large contribution of mobile sources to air emissions. |
| On-Road Mobile Source | An on-road mobile source is any mobile source which operates on public roads. This category consists of automobiles, trucks, buses, and motorcycles. Typical emissions from this category include hydrocarbons, carbon monoxide, oxides of nitrogen, and particulate matter. |
| Off-Road Mobile Source | An off-road mobile source is any mobile source which operates off the paved roadways. This category includes aircraft, trains, construction and farm equipemnt, and other non-road engines and vehicles. Typical emissions from this category include hydrocarbons, carbon monoxice, oxides of nitrogen, and particulate matter. |
| Network Protocol | the language your computer uses to communicate with other computers on the network. |
| Peer to Peer | a type of network where each system shares its own resources and handles its own security. |
| Client-server | a type of network where a central server handles all security and file transactions. |
