I have reviewed the application per your request for subsidence and seismicity. Items reviewed
included your memorandum; J.E. Stover & Associates, Inc letter of February 28, 2006 (Stover
letter); the Permit Application Package, the revision application, and the BLM letter of February
28, 2001 (Amended Special Stipulations). I did not review this application for impacts to
hydrologic features (defer to Kent). Overall, the application well describes the proposed changes.
General subsidence issues associated with the proposed mining changes include the restrictions
from mining under Dove Creek and Dove Cave by the BLM leases, and protection of the Bruce
Park Dam and Terror Creek Reservoir.
Rule 2.04.3(c) See the Rules for the text of his rule. See Rule 2.10.3(1)(k).
Rule 2.04.4(1) The application shall contain a description of the cultural and historic resources
listed or eligible for listing on the National Register of Historic Places and significant known
archaeological sites existing on the date of application within all areas proposed or likely to be
affected by surface activities or planned or probable subsidence over the life of the mine. The
description shall be based on all available information, including, but not limited to, data of
State and local archaeological, historical, and cultural preservation agencies.
Pages 2.04-9 and 2.04-9i and Volume VI of the PAP is such a description. This revision adds two
sites. Page 2.04-9i should be revised to include this revision.
The Stover letter of February 28, 2006 addresses, in paragraph 3, Dove Cave. Concluded in the
cultural survey (Volume VI) is that the Ruben Dove Shelter (or Dove Cave) site 5DT1325 is not
eligible for nomination to the National Register of Historic Places (NRHP). The BLM amended
special stipulation (BLM letter of February 28, 2001) states "(4) The lessee/operator is required
to take measures to ensure that Dove Cave is protected from the negative effects of subsidence,
and that it's structural integrity is maintained."
