If trees are planted, there shall be six hundred (600) surviving stems per acre after two (2) growing seasons. If the Division determines this level of revegetation is not practicable at a given site, the operator shall (1) revegetate to the extent practicable and (2) provide surface stabilization for the entire site.Tenn.
