Officials hope to learn today what can be done to extinguish an underground fire burning for more than four months and polluting the air. Mayor Peter Christie was notified in a text message from Fire Chief Steve Sims on Thursday state and federal officials and contractors would be at an old stump dump site today to explore options to put out the fire. Heinz Braun with the Arkansas Department of Environmental Quality said Thursday the federal Environmental Protection Agency would bring in experts today to best determine how to fight the fire. Braun was in Bella Vista on Thursday. The fire along Trafalgar Road is on a site where the Bella Vista Property Owners Association operated a stump dump for about 13 years.
