John/Kyle:
As requested during our meeting on 10/10/08, please find the attached file
illustrating typical mining equipment relocation path cross-sections.
(See attached file: Dragline Walkpaths.pdf)
Please note that these are typical cross-sections. The actual required
width for an equipment relocation corridor must be evaluated on a
case-by-case basis. Evaluation criteria that could require variations in
the width dimension may include:
turns or curvature in the walkway path
geotechnical considerations of the underlying soils and proximity to
excavations
drainage considerations (if in proximity to drainage features)
relocation of utilities (roads, powerlines, etc.)
Please let me know if you have questions or require additional information
with respect to this information request.
What is the status of DWQ's groundwater monitoring plan expectations?
Thanks.
Ross
