If you don't want folk to use it just plough it up.
You have no responsability to maintain it whats so ever if you don't want to use it.
And nobody can land on it without your permission unless its an emergency.
And as for decommissioning its however long it takes for a tractor to pull a raper through it. No need to tell anyone.
