The Division of Reclamation, Mining, and Safety (DRMS) has completed our review of
TR-46 regarding the request for retaining stock pond T-3 as a permanent structure.
Seneca Coal Company (SCC) updated Appendix 13-9 to include T-3 as permanent and
provided an As-Built Drawing for the stock pond. A stability analysis for all stock ponds
is provided in Appendix 13-9A. SCC previously included Stock Pond T-3 in the Hazard
Evaluation provided in Appendix 13-9; this written safety demonstration is required by
4.05.9 (18) to waive the quarterly inspection frequency requirement. The DRMS has the
following comments regarding the request for permanent impoundment Stock Pond T-3.
In accordance with Rule 2.05.5(1)(b), the post-mining land use description "shall
be accompanied by a copy of the comments concerning the proposed use by the
legal or equitable owner of record of the surface of the proposed permit area and
the State and local government agencies which would have to initiate, implement,
approve, or authorize the proposed use of the land following reclamation."
Therefore, SCC needs to provide comments from the landowner on which the
proposed permanent stock pond is located. Please contact the appropriate
landowner(s) and forward their comments concerning the proposed permanent
stock pond T-3 to the DRMS for inclusion into the permit application package
(PAP).
2. In accordance with Rule 2.05.5(1)(b), SCC also needs to comply with other State
and local government agency requirements. The Office of State Engineer does
have jurisdiction over this permanent stock pond following reclamation of the
land. According to a telephone conversation on October 3, 2008 between Mr.
Mike Boulay (DRMS) and Mr. Craig Lis of the Office of the State Engineer the
stock ponds at Seneca II Mine are considered small Livestock Water Tanks and
the Office of the State Engineer needs to be notified of all dams constructed for
these "Stock Ponds". Please contact the local Division of Water Resources office
in Steamboat Springs to ensure that the proper notification procedures are
