the Division's decision due date. Please be advised that if you are unable to satisfactorily
address any concerns identified in this review before the decision date, it will be your

1. In the letter dated December 12, 2011, the Division asked the Applicant to specify how the
pit walls would be reclaimed to 3H:1V using wet mining methods. The Applicant did not
include this information in the response received on February 2, 2012. Please describe how
you will ensure the reclaimed slope will be at a 3H:1V grade when the pit walls are
submerged by groundwater.
2. The typical cross section of the Flood Control Berm provided on the Mining and
Reclamation Plan Maps shows the reclaimed grade will be 3H:1V from five feet above and
five feet below the anticipated static water level. Rule 3.1.5(7) requires that slopes not be
steeper than 3H:1V from five above and ten feet below the anticipated static water level.
Therefore, the Applicant must revise the maps to show the reclaimed slope will be no steeper
than 3H:1V ten feet below the water level.
3. The Applicant has stated a berm will be constructed on the north and south sides of the
affected area. The Mining and Reclamation Plan maps show that the berm will be
constructed around the entire perimeter of the affected area. Please clarify if the berm will be
constructed only on the north and south sides of the affected area or around the entire pit. If
the berm will only be constructed on the north and south sides of the affected area, then the
Mining and Reclamation Plan maps must be revised accordingly.
