Wildlife habitat ie a planned post-mining land use. The applicant
has selected appropriate plant species and distributions to
benefit fish and wildlife. (4 .18(4)(i)).
XIV. Protection of IInderaround Mining
The Division proposes to approve a variance to allow surface coal
mining activities to be conducted within 500 feet of an active or
abandoned underground mine. The &mpire Mine in the proximity of
the C pit is located within 500 feet measured horizontally of an
active pit. More than 800 feet of vertical separation exists
between the surface pit floor and the underground workings. An
appropriate blasting plan is in place to insure the safety of the
underground miners during Trappers' blasting operations. Mining in
this area is projected to be complete by June of 1993. Approval
for such activities has been granted by MSHA and Colorado Division
of Mines, and improved resource recovery, abatement of water
pollution, and elimination of hazards will result. (4.19(1) and
4.22.4(1)).
XV. Subsidence Control
No specific approvals are granted to the applicant under this
section.
XVI. Concurrent Surface and Underground Mining
No specific approvals are granted to the applicant under this
section.
XVII. Operations on Alluvial Vallev Floors
Operations on alluvial valley floors are discussed in Section 4.8.4
of Vol. IV of the permit application.
The Division has determined that alluvial valley floors exist
within the adjacent area. Therefore, the following findings are
in order for the alluvial valley floors known ae the Yampa River
AVF, the Williams Fork AVF, and the Flume Gulch AVF.
The Division finds that activities proposed by the applicant will
not interrupt, discontinue, or preclude farming on the alluvial
valley floors that are irrigated or naturally subirrigated.
(4.24.3 (1)) .
The proposed activities will not materially damage the quantity or
quality of water in the surface or ground water system described
above. (4.24.3(3) and 2.06.8(5)(a)(ii)).
The proposed activities will comply with the requirements of the
Act and the Regulations with respect to alluvial valley floors.
(2 .06.8 (5)(a)(iii)).
Surface coal mining and reclamation operatioae will be conducted
to preserve the essential hydrologic functions of alluvial valley
floors outside the permit area and to reestablish the essential
hydrologic functions of alluvial valley floors within the affected
area throughout the mining and reclamation process. (4.24.2).
An environmental monitoring system shall be installed, maintained,
and operated by the permittee on all alluvial valley floors during
surface coal mining and reclamation operations and continued until
all bonds are released in accordance with Rule 3. (4.24.4).
