Dr. Corley, the landowner, also attended the inspection. The Southfield <br />Mine was an underground mine which the Division has revoked the bond and terminated the permit. Therefore, no <br />mine operator remains. The primary focus of the inspection was potential reclamation and maintenance work <br />along the Magpie Diversion. All bond monies available to the Division will be utilized as needed for reclamation <br />and maintenance activities. The weather was clear and ground conditions were dry. Temperatures during the <br />inspection were around seventy degrees fahrenheit. <br /> <br />RECLAMATION SUCCESS - Rule 4.15, Rule 3: <br />The Southfield Mine permit boundary is broken into three non-continuous areas; the substation pad, NW-MW well <br />pad and associated roads and the Magpie Diversion. Each portion of the site was inspected. <br /> <br />The reclaimed substation access road vegetation showed increase in vegetation from encroachment from the <br />adjacent areas however is intermittent and patchy. Some areas along the reclaimed road remains sparse due to <br />usage post-reclamation. No recent use on the road was observed. The reclaimed substation pad is established with <br />vegetation. The area blends well and is becoming indistinguishable from the adjacent undisturbed lands. No issues <br />were observed <br /> <br />The reclaimed road spur and access road to the NW-MW well were inspected. The road spur is very well <br />vegetated and blends into the adjacent undisturbed lands. The access road for the NW-MW well continues to show <br />increased vegetation concluding shrubs and cacti. The NW-MW well pad is also stable with increased vegetation.
