ABSTRACT
Air pollution surveys are unique in their development and conduct. Depending on the objectives of an air pollution survey, a mobile or fixed sampler can be used. Other than the obvious considerations such as accessibility and the relationship to interfering pollutant sources, the principal factors in site selection are meteorology and topography. In selecting a plant site, planners should consider the air pollution climatology of the area. In plant planning, planners should consider local, state, and federal air pollution authorities, which can shutdown or curtail plant emission activities during times of air pollution emergency. Plants must have standby plans ready for reducing the emission of air contaminants into the atmosphere. A plant must control emission rates to ensure that problems do not occur even during poor dispersion conditions. This control requires full knowledge the frequency of poor dispersion weather. Weather conditions should be considered when plant start ups are scheduled or major repairs that may produce more emissions are undertaken.
