Fill areas will not, therefore, be suitably: far structural support without additional geotechnical A r engineering. Compaction of the final surface of all graded areas will be performed to Cc limit.surface erosion. bu co The surface of the areas shall be prepared and planted with grasses as recommended to in the approved Reclamation pian. Temporary silt control fences shall be placed to fin control any sediment that might be eroded by precipitation run-off before sufficient tht erosion control vegetation is established. With sheet flow drainage and erosion controlling vegetation established, surface drainage conveyance or collection Qu structures should not be necessary. col 9rt 2.2 Previously Mined Areas (Areas 2. 3 & 4) The surface of the previously mined areas designated as Areas 2, 3 & 4 cover 3.: approximately 2.9. 2.7 and 2.5 acres, respectively. Reclamation of these areas shall consist of debris removal and disposal,recontouring the disturbed areas and reseeding Tal those surfaces with grass. The disturbed areas shall be reshaped as specified to 1s promote sheet flow drainage with limited ponding. As with Area 1, except for the drs final ground surface, fills will not be compacted and some settlement is expected. del These fill areas, therefore, will also not be suitable for structural support without apl additional geotechnical engineering. Compaction of the final surface of an graded gra areas will be performed to limit surface erosion. be The recontoured and disturbed surfaces of Areas 2, 3 & 4 shall be reclaimed in conjunction with and in the same manner as Area 1. 3A Thi 2.3 Misceitaneous Areas duf frog The three structural concrete pads that are indicated on the Grading Plan, including one concrete containment structure for above ground storage tanks and two small Tho concrete pads, shall also be removed and disposed. A representative of the Sart cor Joaquin County Department of Environmernal Health shall be present during the the removal of the concrete pads in case any unanticipated hazardous materials or contamination are uncovered. Should hazardous materials or contarnination be Thy encountered in any excavation, work will tease in that area. Removal-, further des disturbance and/or remediation of any hazardous materials or i;vntaminatlon ade discovered as a part of the reclamation work will be performed by others. or t Certain other other earthwork drainage and erosion protection improvements, adjacent to plat the siltation ponds and elsewhere, will be completed as directed in the field by wir Condor.
