CORNING, N.Y. -- N.C. Department of Environment and Natural Resources recognizes Corning for superior environmental performance

Corning Incorporated (NYSE:GLW) announced today that its Wilmington, N.C., optical fiber manufacturing facility has been named an Environmental Steward by the N.C. Department of Environment and Natural Resources (DENR). The award recognizes the Wilmington facility's superior environmental performance, commitment to continued reduction of its environmental impact and demonstrated commitment to go beyond compliance. Corning is today being recognized by DENR Secretary William G. Ross, Jr. and Assistant Secretary Jimmy Carter at a ceremony in Wilmington.

"At Corning, we are firmly committed to protecting the environment through continuous improvement of our processes, products and services," said Tom Nettleman, division vice president and plant manager for Corning's Wilmington optical fiber manufacturing facility. "Through our rigorous environmental management system, we hold ourselves to the highest standards of excellence and are honored to receive this state-level recognition of our efforts."

"Corning continues to set the bar in the development of management systems for efficient and environmentally friendly manufacturing," said DENR Secretary William G. Ross Jr. "The company serves as an example that industry can be both successful in commerce and a steward of the environment in which it operates."

The state's Environmental Steward initiative began in 2002 and was designed to promote and encourage superior environmental performance by N.C.'s regulated community. An Environmental Steward is an organization that has demonstrated environmental leadership through its commitment to exemplary environmental performance beyond what is required by regulation. Stewards are required to set aggressive environmental performance goals that include pollution prevention, a commitment to exceed compliance and annual improvements to performance, as well as annual reports on its environmental performance. The Steward is the highest level of recognition and is reserved for those organizations that have demonstrated and pledge a continuing commitment to achieve high environmental performance.
