A summary is presented of the results of a detailed statewide emission inventory of particulate, sulfur oxide, hydrocarbon, carbon monoxide, and nitrogen oxide sources of atmospheric pollution. Questionnaires were sent out, of which approximately 530 were returned. Using these data over 800 sources were selected for point source processing using any source emitting one ten per year or greater. These sources were coded in detail and processed as point source data. Additional data on statewide fuel usage, vehicular traffic, waste disposal, solvent evaporation, aircraft activity, agricultural fuel use, gasoline handling losses, petroleum storage losses, and natural gas production losses were collected and processed as area sources. The report also provides: a summary of computer processing results; a task description; definition of the grid coordinate system used; and details of the methodology employed in accomplishing this task.
