Subsidence Handbook Volume III, Exhibit 15 <br />ROADS AND TRAILS <br />Introduction <br />Numerous jeep trails cross areas of predicted substantial subsidence. However, <br />subsidence should not result in serious damage to the roads provided surface fracturing <br />and cracking does not accompany the subsidence. Any minor damage which occurred <br />could be readily repaired with a grader and /or dozer. Portions of Terror Creek Road and <br />Hubbard Creek road are within the permit boundary and adjacent area. The Stevens Gulch <br />Road bisects the permit area and consists of a maintained gravel road surface. Secondary <br />roads and trails are present in the permit boundary and adjacent area. <br />Worst -Case Damage <br />A subsidence crack could develop along trails and light use roads, causing a hazard to <br />traffic. Large rocks could fall or roll onto trails and light use roads causing temporary <br />closure of the roads or tails and posing a hazard to traffic and personnel. Subsidence <br />cracks could occur in Stevens Gulch road. <br />Pre - Damage Monitoring <br />Bowie Resources will monitor conditions of low- traffic trails as persons travel on unusual <br />environmental resource monitoring. Any problems will be noted and documented in the <br />"Annual Subsidence and Hydrology Report". <br />Any subsidence - induced problems identified by the trail users will be documented. The <br />vast majority of trails have been constructed and are used by Bowie Resources. This is <br />especially true in the first permit term. <br />Stevens Gulch road will be monitored weekly during active subsidence, quarterly for one <br />year after subsidence, and then annually thereafter. <br />Post - Damage Monitoring <br />Post - Damage monitoring will be conducted like pre- damage monitoring. <br />PR -14 45 06/14 <br />
