(FORM 2 - Public filing) <br />8. Describe the estimated topsoil depth and how topsoil will be salvaged, stockpiled and redistributed for the re- establishment of <br />vegetation. Specify approximate topsoil redistribution depth: <br />Topsoil in the NOI area is estimated tobe 40 -60 cm thick. If leveling of drill pads is <br />necessary, topsoil will be stockpiled for replacement during reclamation to ensure <br />re-establishment of vegetation. <br />9. Describe how drill holes will be plugged (refer to Rule 5.4 of the Rules for required abandonment procedures): <br />Each drill hole will be abandoned using a portland cement and 5% bentonite mixture from the bottom to <br />teet trorn the surtace.

Describe how portals, adits, shafts, ponds, excavations, or other disturbances will be reclaimed (refer to Rule 3 and Rule 5 for <br />specific reclamation performance standards). You may wish to contact the Division for closure specifications. <br />Mud pits will be given time to evaporate and settle before being backfilled. Once backfilled, the mud pits will <br />be allowed to settle again and fUrther dry out befbre final recontouring of the disturbance. in the weeks <br />fnllnwang the nnmplpfinn of drilling, tha rlicti jrhanra will ha rarnntnurPrl to hp-qt match tha original <br />topography and the topsoil will be replaced.
