OKLAHOMA CITY METROPOLITAN AREA POLLUTANT EMISSION INVENTORY

Five categories of emissions were examined--transportation, stationary fuel combustion, solid waste disposal, industrial processes and, evaporative losses. Each of these sources was evaluated in two subgroups - point sources and area sources. Natural gas is virtually the only fuel used in the Oklahoma City Metropolitan area. Forty-eight sources having emissions greater than 0.5 tons/day of any pollutant were classified as point sources. Remaining contributors were considered collectively as area sources. Estimated annual emissions in the Oklahoma City metropolitan area for September 1969 are listed. Sulfur oxides totaled 2200 tons. Motor vehicles contributed 84 percent of the sulfur oxides. Aircraft and railroads account for 8 percent. Particulates totaled 14,200 tons. Light industrial processes contribute 50 percent of the particulate emissions. Transportation contributes 29 percent, refuse disposal 15 percent and stationary fuel combustion 8 percent. Carbon monoxide totaled 150,700 tons. One-third of the total hydrocarbons can be attributed to the production of crude oil. Liquid propane gas plants contribute 17 percent and evaporative loss from motor vehicles 12 percent. Exhaust gas from motor vehicles adds 20 percent and solvent handling 10 percent of total hydrocarbons. Nitrogen oxides totaled 43,600 tons, of which motor vehicles contributed over 55 percent. Natural gas combustion accounted for 41 percent, with 33 percent attributed to two steam-electric plants.
