-34- The applicant proposes to continue the construction of a waste pile initiated under the interim program permit for the Dorchester No. 1 Mine. This pile contains both underground development waste and coal processing waste from the mine's processing plant and belt press. The reader is referred to Section XVIII, "Coal Processing Waste and Non-Coal Processing Waste" of this Findings Document for a specific discussion of the waste pile. The operation is found to be in compliance with the requirements of this section. XVIII. Bonding -Rule 3 The Division has reviewed the reclamation plan and cost estimates provided by the applicant. The Division is increasing the bond in excess of Dorchester's calculations to include the cost of reclaiming Pond #5, designing and reclaiming the Magpie Creek Diversion, and conducting a stability analysis of the access road to the refuse site. The Division has not required bond to cover potential damages to the Florence city waterline at this time (see Sections VI and XXIII).

The Division is setting the bond required for this permit term at $1,100,000. This bond will need to be submitted and approved prior to the issuance of this permit. XIX.
