...Federal Government. Last month the EPA proposed the first nationwide emissions standards for mowers, garden tractors and other gas- powered garden machinery. The regulations go into effect next year, and by 2003 they are expected to reduce hydrocarbon emissions produced by such equipment 32% and carbon-monoxide emissions...
California is moving even faster and further. The Golden State, which in 1963 became the first to regulate automobile emissions, last year became the first to set strict standards for garden machinery: "the single largest unregulated source of carbon-monoxide and hydrocarbon emissions," according to the California Air Resource Board. Under the new regulations, emissions must be reduced 45% by 1995 and an additional 55% by 1999. The board estimates that annual pollution from small engines in the state is equivalent to 3.5 million new cars running a distance of 16,000 miles each...
...this big, messy, off-and-on brilliant novel, Powers tends to go for flash. He sets off skyrockets, then more skyrockets. Great, arcing bursts of language streak across not just pages but whole chapters. (On pollution: "Maroon-brown patinas of condensing air . . . the noxious residue, the breakdown skeins of hydrocarbon linkages . . .") Then, before the afterimage can fade, the bedazzled firmament detonates again in grander, wilder colors. Great stuff, the reader thinks, and does anyone have an aspirin...
...breaking down. Several large colonies of murres, a seabird, have not produced any chicks in the years since the spill. Harlequin ducks, black oyster catchers and other animals have been contaminated by eating oil-drenched mussels, and sea-otter populations are hemorrhaging, literally and figuratively -- a side effect of hydrocarbon poisoning...
...bulky and dirty. Sulfur oxides (SOx) and nitrogen oxides (NOx) have been indicted as principal villains in the formation of acid rain. More than half the nation's electricity is produced by power plants that burn coal. By running finely ground coal through a chemical bath (currently pentane, a hydrocarbon similar to butane), the Otisca process separates out all but 1% of the mineral content, or ash, and 0.5% of the sulfur that forms sulfur oxides when it burns. Because it is half water, Otisca Fuel produces a cooler flame than straight coal does and hence about half the nitrogen...
