Data was collected for: fuel usage for Missouri and its smaller political jurisdictions: refuse disposal by type and amount of disposal; and developing apportioning factors for distributing emissions among the various counties. Point source data was provided by the Missouri Air Conservation Commission. Hydrocarbons, carbon monoxide, and nitrogen oxides were estimated for the gridded areas in the Kansas City and St. Louis AQCR's as well as all five pollutants (particulates, and sulfur oxides also) for the grids in Greene County based on source totals and apportioning factors provided by the State and local agencies. The pollution data was formatted in accordance with the requirements in the Federal Register and other guidelines. The data are presented in two forms: pie charts and tables. The sources tabulated are: Power Plants; Point Sources; Other Combustion; Incineration; Open Burning; Automotive; Other Mobiles and Other.
