Cripple Creek & Victor Gold Mining Company ("CC&V") is in receipt of your recent
A* tion" letter of the Cresson Project Mine Life Extension project sent to the attention of the
Teller County anning Commission. We were somewhat surprised by the tone and approach of
the letter as CC&V has voluntarily worked with Park Center Water District providing data
related to the flows of water from the Carlton Tunnel as well as information about the Cripple
Creek Mining District and surrounding areas. CC&V also has cooperatively worked with you on
the Fourmile Creek Water Quality Assessment and is working with Park Center Water District
on our ongoing mutual interest in finding a potential alternative water source for the Fourmile
Creek drainage. However, your recent letter to the Teller County Planning Commission as an
"objector" to the Cresson Project Mine Life Extension sets a different tone to our relationship
and requires this written response.
CC&V is meeting our responsibilities at the Carlton Tunnel, including the water quality
limitations stipulated in the Colorado Water Quality Control Division ("WQCD") discharge
permit for the flow of water from the Tunnel. As we previously described to your board, the
Carlton Tunnel drains a regional water table that includes the volcanic rocks in a general area
between the cities of Cripple Creek and Victor. The CC&V Cresson Project is a part of that
regional drainage area with any surface flows from the Project captured by on-site sediment
control ponds and any infiltrating water needing to traverse somewhere between 2,000 and 3,000
feet of rock before reaching the regional ground water table. Realize, also, that the Carlton
Tunnel is some six or so miles distant from the Cresson Project area as the crow flies. Given
these and other factors, the WQCD has not classified the flow of water from the Carlton Tunnel
as mine drainage and that flow represents regional ground water that has been draining since
completion of the Tunnel in 1941. As noted in your letter, the quality of the water flowing from
the Carlton Tunnel has been relatively consistent since well before the Cresson Project started in
1994, including the sulfate levels that you note are of concern at the Park Center Water District
