AIR POLLUTION INVENTORY, STATE OF MINNESOTA

Emission inventory data were collected to provide specific information appropriate to the calendar year 1970 on area and point sources for five air pollutants: particulates, sulfur oxides, carbon monoxide, hydrocarbons, and nitrogen oxides. The overall methodology employed centered on correctly apportioning various types of fuels, process emissions, and combustible solid waste. Totals for all types of emissions sources were determined from the tabulated sources. The fuels and solid waste were apportioned according to population and applicable land use variables in each region. Once subtotals had been established for fuels and solid waste for the seven air quality control regions in the area, the quantities reported by point source questionnaires were subtracted resulting in the quantities of fuel that would be available for area source apporting. Specific source types whose emissions contribution to each of the seven regions was estimated were coal, residual and distillate oil, natural and bottled gas, domestic and other wood burning, open burning and incineration, solvent evaloration, diesel vessels, railroads, diesel motor vehicles, gasoline motor vehicles, and gasoline evaporation. For each source type, specific methods of estimation are described.
