Non-Ferrous SmeltingâSudbury INCO Limited, the world's largest nickel producer, which mines ore with heavy sulphur content at its Sudbury mining and smelting complex, is the con- tinent's largest single source of SO2 emissions. It accounted for per cent ( million short tons) of total North American emissions in 1975, according to the Research Croup's report. Since INCO's emissions of NOx are negligible, the company accounted for per cent of the total com- bined Canada and emissions of SO2 and NOx, the major percursors of acid rain. INCO has cut its total SO2 production in its Sudbury operations by over 40 per cent since 1969 by the production of sulphuric acid. This reduction, coupled with "superstack" dispersion since 1972, has produced substantial air quality improvement in the local Sud- bury area, which at that time was the primary objective. From the outset, the tall stack approach was iden- tified as an interim pollution control measure and not as a final step in abatement at the company's Sudbury facilities. As a first planned step aimed at reducing current SO2 emissions in the Province, Environment Ontario Minis- ter Harry Parrott announced on May 1,1980 the gov- ernment's intention to establish new control measures on INCO. The proposed program would bring about a reduction of INCO's emissions of SO2 from the level of 3,600 tons permitted in a former Control Order to 2,500 as a first step, and 1,950 tons per day during
