DowDuPont's Yerkes plant in the Town of Tonawanda will undergo a leadership change.
Warren C. Hoy, the plant manager for more than five years, will retire later this month. His successor will be David Ledesma.
Hoy is a Tonawanda native. He began his career with DuPont, which merged with Dow Chemical last year, as an engineer at its Niagara Falls plant in 1981. Hoy worked for DuPont at a number of jobs in different states before returning to the region in 2012.
The Yerkes plant makes Corian, a tabletop material, and Tedlar, a thin film used in applications such as solar panels. The site has about 600 employees.
