Reference: R~onse to Your Letter of June 8. 1995.
Dear Mr, Keffelew:
In response to your letter of June 8, 1995, received in this office on June 12, we appreciate your
acknowledgement of the appropriateness of terminating.the humidity cell tests. With respect to
last part of your letter, you state that the overburden has the potential W violate applicable water
quality standards for surface water or jeopardise existing or potentiatefuture uses of ground
water. Apparently your letter was prepared prior to our meeting of May 28, 1995 in which all
in attendance agreed that the concern of the Office about temporary'. modifications of surface
water criteria was not justified. Further, this just-now-received letter appears to have been
prepared prior to your receipt of our letter dated June 5, 1995 in which we responded to all
points made in your letter of May 30, 1995.
The use of ground-water in this Mining District is as recharge to surface water. If you have
cucaminod the record, there are no wells in the Cripple Creek Mining District. Therefore, and
as represented by spring flow arising in Arequa Gulch, and as evidenced by the ground-water
quality data that the Cripple Creek & Victor Gold Mining Company has and is collecting, the
objective is to protect existing quality in a manner that protects surface waters as thgy now exist.
The Cripple Creek & Victor Gold Mining Company has previously responded to all requests of
the Office of Mined Land Reclamation for information regarding the deposition and management
of overburden. The Cripple Creek & Victor Gold Mining Company has submitted a
management plan for that overburden on December 29, 1994 and has not received any
documentation from the Office of Mined Land Reclamation that disproves the humidity cell
results and the comparison thereof to ambient water quality. Thal December 1994 submission
satisfied the applicable permit requirements. It was initially submitted as a Technical Revision
but, if my records are correct, was modified at your Office's request such that it may not be
considered a technical revision. If the Office is asking that we resubmit our December 29, 1994
management as a Technics[ Revision such that approvals may precede, we wsl! be pleased to do
