...Challenge. Ruckelshaus also issued final regulations on exhaust-testing procedures, making them a bit more lenient than before. The old tests simulated a 71-mile urban auto trip, starting with a cold engine (which throws off more pollutants than a warm one). To approximate more closely the way a typical car is used during a day (the engine is often already warm from a previous trip), the new rules call for tests from warm and cold starts; this procedure should reduce the average emissions during tests, helping Detroit to meet the standards...
...Palm Coast development, aims to eliminate the "optical pollution" caused by rows of identical houses. He is using many architectural styles and requiring others who build in Palm Coast to do likewise. Noise pollution will be eased by siting residential areas far away from major highways. To reduce auto-exhaust pollution, shopping and commercial centers will be placed within walking or biking distance of most residents. Industry will be mostly light; factory builders must submit strict pollution-abatement plans before starting construction...
Texas Works has only two smokestacks, and these emit almost no smoke. The two giant 200-ton furnaces are fueled by a careful mixture of natural gas and air that is almost smokeless, and 25,000-h.p. fans blow the few exhaust fumes through a cooling water spray that removes all solid particles. The ultimate discharge from the stacks is made up of relatively equal parts of warm oxygen and carbon dioxide...
...Hawaii's Visitors Bureau, chambers of commerce and hoteliers, travel agents throughout the U.S. last week began receiving a brochure entitled Facts You Should Know to Appreciate Fully the ALOHA STATE!

...fight against pollution themselves. Many stores now label the phosphate content of detergents that they sell, thus encouraging housewives to choose a brand less likely, after sewage treatment, to befoul waterways. Denver's King Soopers has even installed special mufflers on its delivery trucks to reduce their exhaust fumes. Still, few supermarkets have carried environmental concern to such lengths as Alexanders, a ten-store chain in Los Angeles with annual sales of $25 million. At the urging of his daughter Chris, 20, Owner Veryl Alexan der, 44, has made antipollution measures the main theme of his entire operation. Since...
