The toe of the mining slope is shown on the Mining Plan Map. The clay material used to create the final
reservoir reclaimed sideslopes is excavated from the bottom of the mining area. The reclamation cost
estimate for the volume of material needed to create the reservoir side slopes (as shown in the detail on the
Reclamation Plan Map) can be calculated based on the known toe of mining slope. We previously provided
the Division with an estimated volume of material required to create 6,000 linear feet of clay slope liner, as
consistent with the condition that no more the 6,000 linear feet of slope liner would be incomplete.

Our response to the CDOT letter is attached.
14. Please clarify the mining set back distance for the following locations on Exhibit 3 of 7;
• Wesf side of Pond 1 state the mining setbacks from toe of slope
• North side of Pond 1 state the mining setbacks h'om toe of slope
• Southwest side of Pond 2 state the mining setbacks horn toe of slope to the existing gas
well
• Pond 2 state the mining setbacks from toe of slope to the existing gas lines
• In area 15 of Pond 2 state the mining setbacks from toe of slope.
Please refer to the mining plan map for the requested clarifications.
15. Topsoil and overburden piles will need to be placed so they are not affected by the mining plan.
In particular the east topsoil pile in pond 2 and the southwest piles in pond 2. Please further describe
how the topsoil and overburden piles will not be affected by the mining operation.
The topsoil and overburden piles have been placed so that they are not affected by the mining plan. In
particular the stockpiles that are in the processing area have been placed to help screen the operation from
Weld County Road 27 and to help modulate the noise levels leaving the site. These stockpiles will be
removed when the processing area is removed from sections 17 and 18 so that these areas can be mined
and reclaimed. We have added a note on the mining plan map denoting this.
