The U.S. Army Corps of Engineers Nashville District announces a new firewood policy is now in effect, and seeks the public’s cooperation to prevent the spread of forest insects and disease at campgrounds in the Cumberland River Basin. The new firewood policy requires visitors at the Nashville District’s recreation areas, primitive campsites and 25 campgrounds to use only firewood that has been certified as heat-treated by U.S. Department of Agriculture or state natural resource agency.
