Storecard. Even at the present level, however, electric-power plants are a major source of air pollution: 50% of the sulfur dioxide in the atmosphere, 20% of the nitrogen oxides, 20% of the soot and ash. Can technology reduce this pollution? Yes, according to a new study by the Manhattan-based Council on Economic Priorities, a nonprofit organization that reports to concerned investors (churches, universities, foundations) on subjects involving corporate responsibility. But many utilities have been slow to install proven and existing equipment, the study says, or to develop alternative power sources...
...Leave the city or die." The air is among the worst in the U.S. even on good days, but last week really dramatized the reason for the doctors' concern. On Monday night an atmospheric inversion settled over the city. The sky turned reddish-brown, as clouds of ash, soot, and foundry dust produced by the city's factories were trapped beneath. By Tuesday, the pollution level had risen to 771 micrograms of particulate matter per cubic meter of air, nearly four times the level considered safe by the Environmental Protection Agency...
More than a decade ago, it became clear that the booming West and Southwest would soon need far more electric power. But people in Phoenix or Los Angeles did not want to live next door to generating plants that spew soot and noxious gases, discharge hot water and spawn unsightly transmission lines. As a result, the area's electric utilities decided to build new plants as far away from people as possible-in the desert shared by Arizona, Utah, Nevada and New Mexico. Eventually, a consortium of 23 public and private organizations in seven states were involved in planning...
...step toward a solution, industry experts testified, is to equip the plants' stacks with electrostatic precipitators and wet scrubbers that would cut air pollution by 99%. But environmentalists retorted that even 1% of the huge plants' gases and soot will constitute much more pollution than New York or Los Angeles power plants now produce. Each day, according to environmentalists, the complex will emit 1,970 tons of poisonous sulfur dioxide, 1,280 tons of nitrogen oxides and 240 tons of fly ash. Obscuring the nation's clearest skies, the soot would cripple the region's astronomical...
INDUSTRY emits most sulfur oxides and particulates (soot, fly ash, heavy metals). Clean air now means a maximum 80 micrograms of sulfur oxides per cubic meter of air and 75 micrograms p.c.m. of particulates as an annual mean. Both sources emit about the same amounts of nitrogen oxides, which the rules now limit to .05 p.p.m. of air. Both also contribute to photochemical oxidants, which are formed by the action of sunlight on hydrocarbons and nitrogen oxidants. The new rules limit photochemical oxidants to .08 p.p.m. of air. All this could sharply reduce present levels of air pollution. CO levels...
