2.06.4 BteEp Slope Minim.
(1) The provisions of Rule 2.06.4 are applicable to the mine bench and
portal areas of the Orchard Valley and Orchard Valley West Mines in
that these facilities are established on slopes exceeding 20°.
(a) COVCC does not propose to conduct surface coal mining and
reclamation operations which would leave a plain or pred~ninately
flat area, but on which an occasional steep slope is encountered as
the mining operation proceeds;
(b) COVCC has not obtained a permit for mountaintop rengval mining;
(c) OOVCC's mining permit contains a variance under idile 2.06.5
applicable to the mine bench areas of the Orchard Valley Mine. To
the extent that these benches are covered by the variance, the
provisions of Rule 2.06.4 do not apply.
(2) 'ibis permit application contains sufficient information to establish
that the Orchard Valley Mine operations wvered by Rule 2.06.4 are
conducted in accordance with the steep slope performance standards in
Rule 4.27.3. The portals and benches at the Orchard Valley Mine were
constructed prior to the enactment of s+l(~2A. Design specifications
for the Orchard Valley West Mine are located in Volume 6, Phase III
• Stability Analysis Arrn~wrrlix. Reclamation plan specifications for the
Orchard Valley and Orchard Valley West Mines are located in Volume
6A, Reclaimed Configuration Appendix. Materials addressing the
variance for the Orchard Valley Mine are found in Volume 9, Larri Use
Appendix.
The Orclk-ir~d Valley West Mine portal bench was designed and
constructed in accordance with the performance standards specified in
lh~le 4.27. Urder the provisions of Rule 4.27.3(8) a mine bench cut
and mine bench fill design encompassing the temporary placeunPnt of
material on the downslope was developed by a qualified registered
professional engineer. The design provided the Division with a
thorough analytical demonstration that this alternative was as
environmentally sound and structurally stable as that resulting from
the requirement of Rule 4.27.3(1) which prohibits material from being
placed on the downslope.
In addition, the mine bench fill material placed on the downslope at
the Orchard Valley West Mine comprises a road embarilanent and support
facilities area designed and construc.-ted in conformance with the
requirements of Rules 4.03 and 4.04. The fill material was moved and
plaari in a controlled manner with construction certified by a
registered professional engineer. 'This placement of the fill on the
downslope is allowed under the provisions of Rule 4.27.3 (2).
. (3) OOVCC requests the Division to find, in writing, that in addition to
meeting all other requirements of the performance standards, the
Orchard Valley Mine operations will be conducted in accordance with
the requirements of 4.27.3.
