Reference: Cresson Project: Permit M-80-244: Request For OMLR Concurrence With Use
of Ore Material For Access To and To Construct Riser Pipes In Sump Area.
Dear Mr. Keffelew:
The Cripple Creek & Victor Gold Mining Company ("CC&V") has discussed with you this week
the need to use the Cresson ore to support and hold in place the three pump riser pipes located
in the sump area of the Valley Leach Facility. We transmitted to you a sketch of the general
layout of the ore material that we wished to place. We discussed with you and Mr. Sorenson
the need to have ore in place to hold these risers and to thereby install the pumps. Without such
support, the riser pipes are subject to irregular movement and one cannot access them to install
the pumps. The base material has been placed and the riser plates are seated over their
protective and load-distributing materials. In order that these risers may be extended for the
pumps and the associated hydraulic and electrical connections, we wish to construct these risers
using the permeable material derived from the Cresson ore. In order to place this Cresson
material, we also need to construct a road from the edge of the pad to the sump and provide
adequate room for haul trucks to tum around. This road would also be constructed of crushed
Cresson material, as we discussed yesterday. These aspects are shown on the sketch, which is
submitted here as an Attachment. All material is to be placed as part of the construction
sequence for the risers.
CC&V understands that concurrence by the Office of Mined Land Reclamation with this
constmction procedure would be based on the completion and maintenance of adequate diversion
structures which means that the pumping system for Arequa Gulch is in place and operable and
that diversions azound and related to protecting the Valley Leach Facility are capable of safely
passing the Flow generated by a 100-year, 24-hour precipitation event. Then, if the Office of
Mined Land Reclamation finds on December 14, 1994 that the certification of the valley leach
facility is not acceptable because it does not comply with applicable rules of the Mined Land
Reclamation Board, CC&V agrees that it will remove that material delivered from the Cresson
