Treating Tribes and Counties as Good Neighbors Act This bill revises the Good Neighbor Authority program to modify the treatment of revenue from timber sale contracts under good neighbor agreements with the Department of Agriculture (USDA) and the Department of the Interior. (The Good Neighbor Authority permits USDA and Interior to enter into cooperative agreements or contracts with states, counties, and Indian tribes to perform forest, rangeland, and watershed restoration services on federal land managed by the Forest Service or the Bureau of Land Management.) Specifically, the bill (1) requires Indian tribes and counties to retain revenue generated from timber sales under a good neighbor agreement; and (2) allows states, counties, and Indian tribes to use such revenue for authorized restoration projects on nonfederal lands under a good neighbor agreement. (Under current law, only a state is permitted to retain the revenues, and the revenues must be used for restoration projects on federal land.)
