Site Closure 

 Section VII 



A. GENERAL GUIDELINES 



After mining is completed, material sites should be rehabilitated to 

 return them, as closely as is possible, to pre-mining condition. 



1. The site should be sloped and contoured immediately following comple- 

 tion of operations. In cases where sites consist of two or more 

 aliquots, each should be sloped and contoured as completed. Any 

 seeding and fertilizing should be done in spring or summer. 



2. The work area should be shaped and contoured to minimize ponding 

 and to blend with surrounding features and topography 



5. Access roads, culverts, and bridges should be removed (unless other- 

 wise approved) and the areas restored. Fill ramps at incised banks 

 should also be removed and the bank stabilized (if damaged) to 

 minimize subsequent erosion. 



4. All manmade debris should be removed from the site 



5. All cut slopes encountered during gravel removal or access road 

 construction should be stabilized to prevent thermal, fluvial, and 

 wind erosion 



6. Dewater settling ponds of the clear surface water either by pumping 

 or lowering dikes. Silt may be: 



• Left in place in inactive floodplains and terrace locations; 

 protective structures should be lowered to a level corresponding 

 to the level of the impounded silt
