• Leave the material source bench access road open. Do not rip or block the road.

• Remove all loose, hanging or potentially dangerous Rock on or above the excavated surface.

• Pile and burn all construction slash and combustible debris resulting from use and development of the source, including the preexisting refuse identified at the pre-work meeting, even if it is from outside the material source project boundary except for grass and small shrubs that are incorporated into the overburden. Comply with all open burning regulations in effect at the time of source occupancy. If burning is not allowed, all construction slash and combustible debris become the property of the Contractor, to be treated as noncombustible and removed from material source.

00235.46 Seeding:
