SITE REHAB I L I TAT I ON 



Engineering concerns contribute to rehabilitation mainly if future site 

 development (e.g., erecting of structures) is planned. In this situation, 

 long-term integrity of structures is the primary concern of site rehabilita- 

 tion. Otherwise, the primary purpose of site rehabilitation is erosion 

 control. The main function of erosion control is to prevent degradation of 

 disturbed and adjacent areas. 



Some rehabilitation was done at all study sites worked s i nee 1972. 

 There was no evidence of rehabilitation having been done at any of the older 

 sites. Where final site grading was conducted, it typically included sloping 

 or flattening of stockpiles and overburden piles to blend with the terrain, 

 contouring the site to a maximum 2: I slope, and removal of gravel ramps (not 

 done at the Ivishak and Shaviovik Rivers).
