SIGNIFICANT STATIONARY SOURCES Three significant stationary sources of air pollution are organic solvent usage, combustion of fuels, and operations of the petroleum industry. They are significant both for the quantity and quality of their emissions. Organic solvent usage is a major source of hydrocarbons and other organic gases which participate in the photochemical smog reactions. Rule 66 which was adopted on July 28, 1966, is intended to reduce emissions of photochemically reactive materials. Combustion of fuel oil is a major source of sulfur dioxide, nitrogen oxides, aerosols and unsightly plumes. Rules 62 and 62. 1 promote the reduction of this pollution by the use of natural gas. Petroleum refining and marketing contribute to the emission of hydrocarbons. Rules 56, 59, 61, 63 and 65 and voluntarily adopted practices have reduced substantially hydrocarbon emissions from these sources. (a) Complies with the sulfur limits of Rule 62 (in effect from April 15 through November 15). (b) Complies with the sulfur limits of Rule 62. 1 (in effect from November 16 through April 14). Emissions of Air Contaminants from the COMBUSTION AVERAGE DAILY EMISSIONS OF Air Contaminants From (a) Industrial facilities, other than power plants and oil refineries, which are on interruptible natural gas schedules. (b) Domestic, commercial and industrial facilities on firm natural gas schedules. (a) Complies with the sulfur limits of Rule 62 (in effect from April 15 through November 15). (b) Complies with the sulfur limits of Rule 62. 1 (in effect from November 16 through April 14).
