OSMRE will review the PAP and will review the State RA's analysis of
unsuitability pursuant to section 522(a)(3) of SMCRA. As a result
of this reviex and again assuming concurrence with the State RA's
analysis, OSMRE can make the finding that the Federsl lands within
the permit area are not unsuitable for mining in accordance with
section 522(b) of SMCRA pursuant to section 522(b) of SMCRA.
The Foidel Creek mine is located within the drainage basin of the Upper
Colorado River, as defined by the U.S. Fish and 'dildlife Service (FWS).
All projects requiring Federal approval in the Upper Colorado River Basin
must take part in the FWS's Windy Gap process. This process is an
evaluation of the cumulative effects of depletions on endangered species
of fish in the basin. Therefore, Twentymile Coal Company must provide a
calculation of the total depletion of surface flow tributary to any
stream in the Ha sin, as a result of operations at this proposed mine.
If you have anyr questions, please call Ron Naten or Richard Holbrook of
my staff at [phone].
