Dear Jared:
For greater continuity and ease of reference, we have iterated your comments
by item in a graphical box, with our comments in blue following:
Hydrologic Balance:
1. Given the proximity of the clay lined pond to the structures located south
and to the west of the pond, the Division believes monitoring the groundwater
elevations in these areas is warranted. Should a mounding problem arise,
monitoring data will be necessary to determine the cause. Two piezometers will
need to be installed, one south and one west of the clay lined pond between the
pond and the permit boundary. The Operator will need to commit to installing
these piezometers and monitoring the groundwater elevations on a quarterly
basis until the site is released by the Division. Please commit to supplying the
results of the groundwater monitoring data in the annual reclamation report
submitted to the Division. Please update the Reclamation Plan map and indicate
where the piezometers will be installed.
Please refer to the included map showing piezometers locations as determined
by C.G.R.S. Please note that the locations are approximate and will be field fit
so as not to interfere with existing obstructions, rights-of-way, easements or
related considerations. All other aspects of the OMLR request in Item 1 will be
complied with.
