Temporary settlement monuments will be installed and monitored for one year prior to cover construction.
Assume that surcharging will be required if settlement data is not acceptable for final cover construction.
Monuments Required for Federal Cell =4.00 ea
All temporary settlement monuments will be surveyed six times.
Surveying will be provided by differential GPS using an existing site system, and using a one person crew.
The analysis of settlement data for the temporary cover will be performed twice per year.

Assume that temporary cover is placed immediately after completion of waste placement and that settlement
monitoring begins immediately. Assume preparation and stockpiling of cover clay and rock materials during
one year of monitoring keeps the construction contractor occupied, reducing the scope of multiple mobilizations.
Assume a supplemental mobilization event to relocate surcharged material and complete final cover construction.

207 COVER CONSTRUCTION
This item includes the construction of the final cover, roads around the embankments, drainage
structures around the embankments, and permanent fencing. The final cover design is
assumed to be consistent with approved plan drawings listed in Groundwater Quality Discharge Permit UGW450005.
Reclamation of the pits, used for erosion barrier and filter material, is covered under a bond with the BLM.
The final cover area funded is based on the area listed in the premature closure plan.
This includes cover that extends past the edges of the waste that is needed to meet the design slopes.
At the time of closure a temporary cover will be placed. Upon completion of settlement monitoring
and surcharging, the remainder of the cover will be placed. Costs for placement of Temporary Cover
are accounted for within Item 205. A conceptual embankment design is shown below. All cover calculations
are based on this drawing. The costs reflect use of an approved Rock Armor Cover.
TOP SLOPE
Assume uniform cover design; construct cover (to the ditch centerline) in accordance with the premature closure plan; Assume 11% of mined volume is overburden.
Note that open cell area limitation during operations will not be exceeded in accordance with the Radioactive Material License.
