5. Upon suspension of construction of the overburden berm, provide temporary seeding
6. Upon completed construction of the overburden berms, provide permanent seeding of
the berm and the roadway frontage, as needed.
7. Upon permanent stabilization of the overburden berms, remove silt fence and
sediment basins (area dependent).
