 What Equipment is Regulated in Fugitive Emission FEMS/LDAR? The equipment regulated under fugitive emission standards are: • pumps • valves • compressors • pressure relief devices • sampling connections • open ended valves and lines • flanges (connectors) • product accumulator vessels • agitators

 What Are Fugitive Emissions? The term, fugitive emission, as used in air quality control, generally refers to any emission escaping from regulated processes (sources) other than via the designed release point (smoke stack, etc.). The point source for a fugitive emission is simply called "a leak." These leaks and emissions are most often associated with the equipment necessary for the movement of process fluids and gasses. The term "fugitive" is used because these emissions are neither calculated in the source design, captured by the emission control equipment/systems, nor are they detected through normal equipment monitoring processes. Since these emissions bypass control equipment, they are also referred to as "uncontrolled enlissions."

 Sources of Air Pollution In discussions of air pollution sources, four terms are routinely used:  Mobile sources  Stationary sources  Point sources  Area sources  Mobile sources Mobile sources are generally related to transportation. Mobile sources are not included within the general parameters for fugitive emissions and, therefore, will be given no further consideration in this course.  Stationary sources Stationary sources define emission sources that are fixed and include all forms and types of manufacturing, chemical and petroleum processing, power generation, and small business facilities. Point sources A stationary point source refers to any place within a facility from which emissions are possible. For a given facility, a stack may be one point source. An emission leak within a process is also considered a point source. An automobile or a truck would represent a point source or mobile source. Area sources Area source refers to any one of severa...
