Environmental

Considerations

Avoid unnecessary stripping and damage to vegetation and waterways. Control dustconditions and limit water erosion by dressing area at the end of each day. Avoidunnecessary equipment usage and follow established procedures for cleanup of fluidleaks. Restore site and surrounding areas as close as possible to the originalecological condition.
