Projections of pollutants produced and released to air and to bodies of water, by Federal Region, from 1975 to 1990 are presented and discussed. These are projections of the Strategic Environmental Assessment System (SEAS), which is a computer model consisting of a detailed sector by sector economic model, and a set of emission coefficients describing regulated levels of control of each industrial sector and region. The conventional air pollutants treated included particulates, sulfur oxides, nitrogen oxides, hydrocarbons, and carbon monoxide. Point source water pollutants treated include suspended solids, dissolved solid, oil and grease, biochemical oxygen demand, and chemical oxygen demand. Certain cases of toxics discharged to air and water from a list of beryllium, cadmium, manganese, nickel, and selenium are also included. The projections are diven by three sets of energy and GNP growth assumptions, spanning from 2.8% to 3.7% per year GNP growth. An interpretation of the National Energy Plan I is used as the set of high growth assumptions.
