AT&T TO ELIMINATE OZONE-DEPLETERS FROM PRODUCT MANUFACTURING

 ATLANTA, April 14 /PRNewswire/ -- AT&T today said it would eliminate virtually all ozone-depleting substances from its consumer and business products manufacturing operations by May 15, two-and-a-half years ahead of worldwide ban on these substances.
 The company said it would eliminate chemicals identified by the U.S. Environmental Protection Agency (USEPA) as class I ozone-depleting substances from manufacturing operations in all its majority owned factories. Class I ozone-depleting substances include all chlorofluorocarbons (CFCs) and ozone-depleting chlorinated hydrocarbons (CHCs).
 The USEPA has stipulated that, after May 15, all products manufactured with class I substances will be required to carry a warning label. Consumer and business products manufactured by AT&T will not need these labels.
 CFCs and other ozone-depleting substances have been used for decades in electronics manufacturing, primarily as solvents. Until the mid- 1970s, these materials were thought to be harmless.
 However, after 1975, scientific evidence began to mount indicating that CFCs were destroying the stratospheric ozone layer that protects the planet from the sun's ultraviolet rays. Increased exposure to ultraviolet radiation can cause skin cancer, cataracts and immune deficiencies in humans, and affects the growth of phytoplankton, which is at the base of the marine food chain.
 "AT&T's elimination of ozone-depleting solvents is an impressive technical achievement, one that clearly sets a standard of environmental excellence for industry worldwide," said Dr. Stephen O. Andersen, deputy director, U.S. Environmental Protection Agency Stratospheric Protection Division. "It shows that global environmental protection can happen when government and industry solve problems together."
 AT&T manufactures hundreds of thousands of products, from microscopic electronic components to the world's largest telephone switching systems in 44 majority owned factories in 13 countries, including 20 outside the United States. AT&T's NCR subsidiary has 22 factorI ozone layer," Andersen said. "AT&T's scientists and engineers developed and commercialized technology that completely eliminates the need for solvents and even improves the quality of solder joints for printed circuit boards.
 "This AT&T technology is a significant contribution to pollution prevention," he said. "And AT&T shares information on alternatives worldwide as a founding member of the Industry Cooperative for Ozone Layer Protection."
