| ISSUES |
REHABILITATION OBJECTIVES |
MEASURES |
| Physical Stability Issues: |
| Safety |
Restrict access to hasardous areas |
- ditch and berm
- fence, and sign post, if necessary
- slope stabilization
|
| Emergency access to water |
|
| Slope Failure |
Prevent deep seated failure, if practical |
- stabilize by flattening slopes or constructing toe berm
|
| Control sediment release, if necessary |
- restrict access with ditch/berm and, if necessary, fence and sign post
- revegetate or place riprap on slopes
- provide stable spillway and overflow channel
|
| Chemical Stability Issues: |
| Acid Drainage and/or Leaching of Metals |
Meet water quality objectives by: controlling reactions and/or controlling migration; collect and treat |
- flood to control reactions
- cover to control reactions and/or migration
- collect and treat
|
| Land Use Issues: |
| Productivity and Visual Impacts |
Return surface to original or approved use |
- backfill pit where practical and beneficial
- flatten slopes
- contour-blend with natural topography
- revegetate slopes
- rehabilitate for fish, waterfowl, wildlife habitat
