Listed below are remaining adequacy review concerns on the above-captioned Regular 112 Application
that will need to be resolved prior to the June ] 1, 2001decision date. Therefore, I would appreciate a
response from you on or before June 1 1, 2001. Please be advised that your application may be deemed
inadequate and may be denied on June 1 1, 2001 unless the following adequacy review items are addressed
to the satisfaction of the Division.
6.4.4 EXHIBIT D - Minin¢ Plan
1. The mine plan map shows that all of Areas 1 & 2 and part of Area 6 occur within the 100-year
floodplain of St. Vrain Creek. Further, all planned areas of excavation, with the exception of Area 4, will
have pit slopes and areas that will be within 400 feet of the channel of St. Vrain Creek. Therefore, the
Division will require that no mining be done within 400 feet of the channel of St. Vrain Creek until the
applicandoperator has provided an approvable Flood ControVMitigation Plan for the Fredstrom Resource.
Such Flood ControUMitigation Plan will need to be submitted as a modification to the permit and will need
to ensure that 1) channel areas, disturbed pit slopes, and on-site structures (where mining will occur within
400 feet of the channel) will be stabilized adequately for anticipated flood flows, and Z) Floodwaters will
be discharged in a controlled manner from any areas of excavation that are within 400 feet of the channel
of St. Vrain Creek. (The Division prefers that the applicant commit to the above measures and incorporate
in[o the permit application). Please respond.
6.4.8 EXHBIT H -Wildlife Information
2. The Division appreciates your cooperation in providing any written commen[s from the Division of
Wildlife (DOW) in order that any DOW concerns may be considered and resolved prior to the June 11,
2001 decision date.
