Under the law, emissions of two noxious gases in auto exhaust-carbon monoxide and hydrocarbons-must be cut by 90% of 1970 levels in 1976-model cars. Techniques to do that, however, lead to an increase in a third pollutant, nitrogen oxides. The law says that, in 1977-model cars, they must be cut 90% below the level in the 1971s. Most auto engineers feel that they cannot meet that second deadline...
...necessary to do so. The automakers can use the grace period. They have already gone about as far toward cleaning up their cars as they can, without introducing costly new technology. GM, for example, reports that it has reduced emissions of hydrocarbons by 80%, carbon monoxide by 70% and nitrogen oxides by 40% since 1967. Such progress, gained by making adjustments on the standard Detroit engines, has been bought at the expense of fuel economy and auto performance: most new cars are hard to start, balk when rapidly accelerated and cough for minutes after the ignition has been turned...
...Detroit says another system, still being developed, would cope with the nitrogen oxides...
...recent book on the subject, Power Over People (Oxford University Press; $7.50), Physicist Louise B. Young gives one possible reason: the discharge of high voltages into the air can produce ozone, a form of oxygen with three (rather than two) atoms in its molecular makeup, and oxides of nitrogen. Ozone can oxidize or "burn" healthy tissue, and nitrogen oxides form nitrous acid and one of the major components of smog. All of these might well affect people and plants that live near the lines...
...power plant is going to be a 2800 megawatt facility. It will burn 27,400 tons of coal each day, and release into the nearby air (according to AP&L's estimates) 469 tons of sulfur dioxide, 14 tons of particulate matter, and 291 tons of nitrogen oxides each day. That's more than any power plant currently in operation in the United States. The power plant will be, according to the Arkansas State Dept. of Planning, "possibly the worst single source of air pollution in the world." It will certainly be a greater source of pollution than the infamous...
