Submit fence removal and stockpile plans to the COR for approval prior to performing work. No woven wire shall be returned to any of the fence permittees or other operators unless approval is given by the Government. Wood and steel posts shall not be cut off at the ground level. Wood or steel posts that break off at the ground level shall be pulled or the stub shall be pushed a minimum 6-inches below the ground surface. Any large holes or voids in the ground from pulled posts shall be covered or filled with appropriate sod or backfill to eliminate any safety hazards. Wood posts shall not be stockpiled and burned on Federal Land.

4.1 METHOD OF MEASUREMENT:

A.
