STAMFORD, Conn.-- Xerox Corporation's El Segundo, Calif., and Wilsonville, Ore., facilities have earned membership in the U.S. Environmental Protection Agency's National Environmental Performance Track, a program for participating U.S. facilities that achieve top environmental performance. With the addition of these two sites, Xerox now has five Performance Track sites and has enrolled all its major U.S. facilities. Performance Track recognizes facilities that voluntarily exceed regulatory requirements, implement systems for improving environmental management, work with their communities, and set three-year goals for further improvements in environmental performance. Only facilities with a record of sustained regulatory compliance and a history of environmental achievements are eligible to participate in the program. "Performance Track recognizes these facilities as environmental leaders because they deliver results beyond what is expected or required by law," said EPA acting administrator Steve Johnson. "These facilities demonstrate on a daily basis that economic prosperity and environmental protection can go hand in hand." As part of its application to Performance Track, the Xerox sites committed to further improving their environmental performance in key areas that include decreased energy consumption, increased solid waste recycling, elimination of hazardous materials from products and decreased water consumption. Xerox's site in Oklahoma City, Okla., was accepted into Performance Track in 2005; Webster, N.Y. and Cincinnati, Ohio facilities were accepted last year. This spring, the EPA accepted the Xerox facilities in Wilsonville and El Segundo, for a total of five covered sites. "Now all major Xerox manufacturing sites in the U.S. are participating in the Performance Track program," said Patricia Calkins, the company's vice president of Environment, Health and Safety. "It's yet another milestone in our long history of demonstrated commitment to environmental performance." According to the EPA, Performance Track -- first started in June 2000 -- has more than 400 members in 46 states and Puerto Rico. To date, Performance Track members have collectively reduced their water use by 1.3 billion gallons and their generation of solid waste by nearly 970,000 tons, increased their use of reused or recycled materials by nearly 77,000 tons, and reduced greenhouse gas emissions by the equivalent of 67,000 tons of carbon dioxide.
