Nov. 9, 2001, Follansbee, West Virginia— Koppers Inc. today announced it will suspend coal tar distillation until further notice at its Follansbee, West Virginia plant because of reduced customer demand.

The Follansbee plant produces a variety of coal tar products, including products for the pavement sealer and roofing industry, carbon pitch used in the making of steel and aluminum and chemicals used to make paint and plastics.

Because of a seasonal downturn affecting companies that utilize the plant's coal tar products in their own operations, Koppers will temporarily suspend coal tar distillation and 42 employees will be furloughed.

" Even with this reduction, our Follansbee plant remains prepared to return to full production as the market rebounds," said Kevin Fitzgerald, Koppers vice president. "We anticipate this reduction to be temporary and will review business conditions during the first quarter of 2002 to assess the viability of restarting coal tar distillation."

Koppers' Follansbee plant serves the aluminum, steel and chemical industries and is a leading domestic producer of naphthalene, which is used in paint and plastics for the automotive, recreation and construction industries. The Follansbee naphthalene plant is the only Koppers naphthalene facility and continues to operate at full capacity.

Koppers is a global integrated producer of carbon compounds and treated wood products for use in a variety of markets including the railroad, aluminum, chemical and steel industries. The Company operates 39 facilities with locations in the United States, the South Pacific (primarily Australia and New Zealand), Europe and South Africa. The Company also maintains an indirect ownership interest in an additional facility in the United States through its domestic joint venture KSA. The Company's stock is shared by a large number of management investors and by majority equity owner Saratoga Partners of New York City.
