Listed below are the second adequacy review comments for the SerFer Pit New 112 Application, File No.
M-2008-006. The Division of Reclamation, Mining and Safety (Division) is required to make an approval or
denial rationale decision no later than August 15, 2008, therefore, your response to the following adequacy review
concerns should be submitted to the Division as soon as possible.
Rule 6.4.3 Exhibit C - Pre-Mining and Mining Plan Map(s) of Affected Lands
1. Exhibit C-2 - Mining Plan Map indicates a 100' setback (typ.) from top of riverbank and ox-bow. Please
commit to a minimum 100' setback from the riverbank and ox-bow and remove the "(typ)" notation from all
areas of the map.
2. Please indicate and commit to a final reclaimed offset from the riverbank to the southern edge of the reservoir.
The Division recommends a minimum 400' offset.
Rule 6.4.6 Exhibit F - Reclamation Plan Man
3. Exhibit F - Reclamation Plan Map indicates a 100' setback (typ.) from top of riverbank and ox-bow. Please
commit to a 100' setback from the riverbank and ox-bow. Please remove the "(typ.)" notation from all areas
of the map.
Rule 6.4.7 Exhibit G - Water Information
4. The applicant states that the entire mine site lies within the 100-year flood plain of the Cache la Poudre River.
In the event of a significant flood event (10-year flood or greater) it is likely that the existing pit will be
captured by the Cache La Poudre River. Wherever mining will occur within 400 feet of the river channel, a
flood analysis and flood control plan must be evaluated and submitted. This would include pit side armoring,
river site armoring, inflow and outflow channels, or other appropriate measures. Accordingly, the Division
requests that the applicant provide the flood elevations(s) to be expected under a "worst case" flooding
scenario and specific mitigation measures that will be implemented to minimize the potential for any offsite
impacts.
