RE: Hydrology and Geology Adequacy Re vie~,~ for the
~° Blue Ribbon Coal Mine - Permit Application No
David C. Shelton
Director
C-047-81
Per your request, .I have conducted a technical adequacy review of the Blue
Ribbon coal mine permit application. In my review, I have found numerous
inadequacies which must be addressed prior to formulating written findings
on this application.
Geology - 2.09.6(2)
The site geology map and cross~~sections (Plate 8 and 9) provided within the
permit application are both illegible and at inappropriate scales. The site-
specific geology should be resubmitted on a legible, Larae contour map with
the mine plan area and permit area clearly drawn. This map should include
the strikes and dips of beds; the cropline of the coals; any faults, fractures,
landslide bodies; contacts of all geological units, including alluvium and
colluvium; the location of all drill holes; and the Location of the cross-
sections. Two new Large-scale geologic cross-sections should be submitted:
One along the dip of the coal beds, and one along the strike of the coal .beds.
These cross-sections should, at a minimum, cover the permit and adjacent areas
for this permit period (5 years). Legible lithoIogic logs and geophysical
logs should be submitted for the permit and adjacent areas (e.g., those
used in the construction of tltegeologic map and cross-sections).
Fly droloyy - 2.04.7, 2.OS.G (3) anr7 4.05
The hydrology sections of the permit application have been taken from permit
applications of adjacent mines. The hydrologic data is sufficient for
regional hydrology, but lacks site-specificity. 7'h~• 1'ollowiny concerns must
be addressed prior to completing written findings on around water, monitoring,
water quality, water .rights, alternative water sunpL7, and cumulative. hydro-
logic impacts.
1) The letter on Wage 40 from P.a1ph V. Kelling of the Montrose Office of
the Division of Water Resources to U.S. Steel adrlresscs adjudicated springs
and water wells. Rule 2.09.7(7) and 2.05.6(3) requires the location of any
springs, the measurin_q of the flow and quality of these springs £or seasonal
fluctuations, and the determination of the effects of Honing and spring flows.
Springs were observed in the F7ubbarc7 Creek valley on a field trip up the
