RE: Completeness - Storm King Mines
2.04.7(2) Surface Water
The permit application minimally addresses the components needed to depict the
baseline surface hydrology for the permit area.
There are several mayor inadequacies that have been identified.
1. The baseline hydrologic monitoring of surface water site CR-2 does not
extend for one year.
2. Surface water site CR-2 has no corresponding flow measurements for
sampling events. If the applicant plans to use flow from U.S.G.S. station at
Grand Junction, this flow data should be submitted for the period covered by
sampling at site CR-2. This data should be presented in a readily usable form
such as hydrographs.
2.05.6(3) Protection of Hydrologic Balance
The description of methods proposed to protect the hydrologic balance is
sketchy but minimally complete.
The applicant has not adequately addressed the effect of subsidence on surface
water. At a minimum the applicant should address changes in stream gradients
and Increased inflows of surface water to the underground system.
2.06.8 Alluvial Valley Floors
The applicant has addressed the minimal requirements of this section.
The following areas are obviously inadequate:
1. The applicant does not address the "Specialty Coal Storage" area located
on the alluvial terrace of the Colorado River. A demonstration is needed that
this coal storage pile will not leach into the ground water. Greater detail
of the main coal storage bin design is needed to evaluate protection of the
ground water;
