Specifically, the mining plans should include at least the following 

 i nf orma t i on : 



• A site sketch drawn to scale showing: 



project I ocat i on 



cross-sections of borrow areas, 



gravel source locations, 



existing or planned haul road locations, 



test pit or boring locations (if any); 



• An estimate of the volume of material that is needed; 



• An estimate of the volume of material that is anticipated at the 

 ava liable s i tes; 



• An estimate of the properties of the material required; 



• An estimate of the properties of the in-situ materials; 



• An estimate of the type and amount of processing that will be required; 



• Project schedules for al I major activities; 



• Preliminary design features of any required support structures, such 

 as access roads, processing plants, culverts, and bridges; and 



• Description of operational and rehab i I i t at i ona I aspects of site use. 



Plans prepared as described above should provide sufficient information 

 to evaluate the appropriateness of the planned development of the gravel 

 sources. 



Mining plans were prepared and submitted to the appropriate government 

 agency for most of the 25 study sites. However, no mining plan information 

 was found for the Washington Creek, Nome River, or Skeetercake Creek sites. 

 The mining was apparently a trespass action at the upstream Aufeis Creek 

 site and for initial gravel removal at the Kavik River site. Only results of 

 a very limited site investigation were found for the Penny River site; only 

 some correspondence was found for the Ugnuravik River site; and only a 

 right-of-way permit was found for the McManus Creek site. Mining plan infor- 

 mation reviewed ranged from sketchy (for the Seward Peninsula sites) to 

 quite detailed (in the case of the Trans-Alaska Pipeline System sites).
