In response to your letter dated January 25, 1999 I have listed the response to each of the
questions you have listed.
1. As required by rule 1.6.5(2), please find attached the proof of pub{ication from the Herald
Democrat (Leadville newpaper).
2. We have received the written comment from the Colorado Division of Water Resources.
We do not believe that a stone water discharge permit is required for this project. We will
get confirmation from the Division of water resources and if a discharge permit is required
we will obtain a permit from the Department of Public Health and Ernironment, Water
Quality Control Division. Also in the Division of Water Resource letter dated January 4,
1999 it was noted that no ground water will be exposed. ACA does not intend to expose
any ground water and any water use will be by a substitute supply plan initiated through the
Division of Water Resources.
3. The mining to the Templeton Ditch will not be mined vertical to the 15 foot and 3 foot lines
denoted on the plan. ACA will maintain a 4;1 slope when approaching the ditch so no
bacldill is required around the ditch. For ease of reclamation ACA will not mine vertically to
arty structure of boundary so backfilling will not be done to any finished slope. Other than
the backfiliing of top soil for final reclamation. As the fetter of agreement with the users of
the Templeton ditch states ACA will repair /reconstruct any damage that may occur to the
ditch due to ACA's operation.
4. As stated previously, ACA will not expose the ground water on the mining site. Any water
used during mining will be purchased through a substitute supply plan with the Division of
Water Resources. The concrete and Asphalt operations will use bartiers to stop any spill Of
fluid that may come into contact with the ground water. Specifically, the protection of
solvents, fuels or greases that may be used will be stored in a lined structure so none of
these fluids penetrate the ground. The use of concrete, impervious liners or other
approved liners will be used to contrd spills.
5. As shown on the mining plan and the reclamation plan ACA intends to mine the property in
phases. The timelines shown in sections D and E show the timelines. The mine and
reclamation maps show the acreage in each of the phases. As I stated previously ACA will
maintain the 4:1 slope as we are mining up to boudaries or structures. ACA feels the
maximum disturbance of 60 acres will be disturbed. It is our intent to reclaim the site as ft
progresses (as shown in our mining and reclamation time lines sect. D & E). An updated
reclamation bond calculation, the mining and reclamation time lines and the seed quote we
are basing the costs on are included.
