Indiana's attorney general is suing a northern Indiana lumber recycling plant with a history of environmental and worker-safety violations.

The lawsuit filed Monday in Elkhart County seeks preliminary and permanent injunctions to halt open dumping of wood wastes at VIM Recycling Inc.'s Elkhart operation. It also asks a judge to order VIM to remove waste materials and debris from its property.

Company spokesman Tom Holt says VIM is "extremely surprised" by the lawsuit. He says the U.S. Environmental Protection Agency has agreed to allow VIM to place wood from the recreational vehicles and manufactured housing industries on asphalt at its property.
