The end is near.

By the fall Winner Development LLC expects to complete all of the environmental cleanup of the former Westinghouse Electric Corp. plant in Sharon.

"We're down to the final phase,'' said James E. Winner Jr., chairman of the Sharon company.

For more than three years Winner's company has toiled to meet cleanup requirements at the federal Superfund site. Renamed Winner Industrial Park, total cleanup costs have been pegged at more than $25 million. Winner Development plans to turn the abandoned plant and offices into a multi-use site.

Sitting on about 18 acres along Sharpsville Avenue, the sprawling complex of 800,000 square feet of industrial space and an additional 166,000 square feet of offices has undergone extensive work to rid the site of toxic materials. The final part of the cleanup calls for special sealants to be coated on about 300,000 square feet of floors.
