At Mount St. Helens, I've seen the USFS use this administrative closure loophole to keep land closed, against their own management policies, plans and without public comment, for DECADES. These "administrative closures" were supposed to be put in place for things like active wildfires but the USFS is using this to circumvent their own public process. There is nothing to stop them from using this to close anything they don't want--all without public comment and completely outside the EIS, NEPA any other official management process. This is exactly what happened at Mt St. Helens. The plan says one thing, but the officials in power toss the plan in the trash, after all the comment and agreement, then do what they want anyway!
Its sort of like Inslee's unrestricted "emergency" powers and orders that go on forever........
