PERMIT
Fill areas of unconsolidated materials (loose soils & waste tailings) shall be sloped at an angle of
2:1 or flatter and seeded according to the vegetation plan.
The entrance road will be left intact to provide access to the property by the landowner for future
uses. Haul roads not used will be graded and crowned, scarified and seeded using the vegetation
plan.
Ditches are vegetated and will be left to grow up and be taken by nature.
Basins and traps will be graded to blend into the natural and surrounding slopes and be seeded
using the vegetation plan
