The Division concurs with this assessment. However, the operator has also specified that the <br />landowner's desires conform to this understanding, and correspondence of which will be provided <br />under separate cover. Please provide written evidence of concurrence from the landowner <br />(Doeringsfeld & Aratas Partnership) for zoning of industriaUcommercial use for these particular <br />areas. <br />Correspondence from Dr. Justin E. Arata, General Partner; Doeringsfeld and Aratas Partnership; <br />dated 25 April 2004, is included with this reply, and should satisfy the Division's remaining <br />concerns as it pertains to this item. <br />3. Excavation Slope Steepness -Setback Distance: VCI has proposed that extraction will occur to <br />within 25 feet of well heads and facilities, and be backfilled as soon as practicable to create a 100 <br />foot radius azound the well head for future well activities. In addition, the operator has provided <br />"no negative effect" letters per Rule 6.4.19( c) from gas structure owners Duke Energy, Merit <br />Energy Company, and Matrix Energy, LLC. <br />VCI has also proposed that excavation slopes be no steeper than 1.25H: 1 V and to maintain a <br />minimum 10 foot setback from the crest of the excavation slope and any potentially affected <br />structure. Based on the slope stability information and analyses provided, it should be noted that <br />the Division will consider minine at an excavation slope of steeper than 1.25H:1 V within 80 feet <br />(two-times the anticipated maximum ait depth) of a structure (except for any structure owned by <br />Duke Enerey. Merit EnerQV Company, and Matrix Energy, LLC), to be a serious violation of the <br />permit that will initiate an immediate enforcement action.). <br />This is understood. The pre-existing conditions pertaining to this item are being actively <br />backfilled and expected to be completed within three months following approval of this <br />Amendment. We request the DMG provide a three (3) month gace period from the approval <br />date to assure conformance ofpre-existing slope conditions adjacent to such facilities to the <br />1.25V:1H standard. All future extraction adjacent to oil and gas lines will conform to this <br />standard. Anomalous conditions with vary from this standard (e.g., small spans of slope not <br />perfected to 1.25H:1 V along oil and gas lines) but not to such an extent as to affect the overall <br />stability of the slope should not be viewed by the Division as a violation of the standard. <br />Anomalous conditions identified by the Division during an inspection will be established to the <br />approved ].25H:1 V slope standard within 30 days subsequent to such identification. <br />6. In conformance with Rule 6.4.4, please clarify the current or planned volume, whichever is <br />greater, of stockpiled overburden that will need to be backfilled into the pit during final <br />reclamation, and provide the average push/haul distance to move the stockpiled overburden into <br />the pit. (The volume of overburden that will be used to backfill Tract D may be excluded from <br />this volume estimate.). For clarification of this item, the Division considers any non-topsoil or <br />non-saleable earth material generated during extraction of aggregate materials to be overburden. <br />An itemized cost for backftlling the stockpiles overburden will need to be included in the revised <br />reclamation cost estimate. Please respond. <br />Van•a Companies, Inc.
