FROM: Hal D. Simpson, P.E., Assistant State Engineer
SUBJECT: West Sunday Mine -Union Carbide Corporation -San Miguel
County #81-21, Application for Mining and Reclamation Permit
As requested by your oi'fice, we have reviewed the application for an under-
ground uranium and vanadium mine near Naturita. The applicant states that
some water will be enc~DUntered in the underground workings of the mine and
that underground sumps will be provided to store this water. The applicant
also states that this seep water will be used for underground mining and
drilling requirements. We view this use of ground water as putting the
ground water to beneficial use which requires a permit to use ground water
in oirler to not be in violation of CRS 1973, 37-90-137. Until this permit
has been obtained, the applicant will be in violation of the above referenced
statutes .
The applicant also status that any excess water that exceeds the underground
capacities would be pumped to the surface and impounded in a series of evap-
oration ponds to be loc~ited and constructed at some later date as they are
required. The applicant would have to obtain storage rights from the Division
7 Water Court in Duran<Io prior to construction of these ponds. If any dams
that will be constructed will be over 10 feet in height from the lowest point
in the valley floor to the bottom of the spillway, the design must be approved
by this office in order to be in accordance with Article 87 of Title 37 of the
1973 Colorado Revised Statutes.

\, We have no objections to the application as long as the applicant obtains the
needed permit and in the future if necessary obtains the necessary storage
rights.
