• 2.05.3 <br />The layout of the roads are presented on Map 9 Hydrological Monitoring <br />Location Map. <br />Light use roads that can easily be traveled with an ATV and may be traveled <br />with a 4-wheel drive vehicle will be upgraded so a drill rig can traverse the <br />road. Light use roads that cannot be traveled with a 4-wheel drive vehicle <br />yet might be traveled with an ATV will be refurbished so a drill rig can <br />traverse the road. Generally upgraded and refurbished light use roads <br />cause about 6 and 12-feet of new disturbance per lineal feet of road <br />respectively. <br />Alight use road was constructed during May and June 2000 to access Pond <br />B. The entrance for the road is from 4365 Lane. The road parallels Old <br />State Highway 133. It is approximately 600 feet long with a uniform grade <br />of about 1.5 percent. <br />As part of the B-seam portal development, two excess material stockpiles will <br />be constructed. The tops of the piles will be material storage areas. Light <br />• use roads will be constructed to provide access to the material storage areas <br />shown on Map 15-1 & 15-2. Both roads are approximately 150-feet long and <br />have maximum grades of about 10%. <br />New light use roads will be reclaimed. Reclamation of the upgraded and <br />refurbished light use roads may involve narrowing the roads so they are <br />compatible with the postmining land use of rangeland and wildlife habitat <br />since roads are necessary to manage both land uses and a light use road <br />network was existing on the property prior to mining. <br />(iii) The haul and access road construction will not alter or relocate any drainage <br />ways so no response is required. <br />(iv) The inlet end of all culverts and ditch relief drains will be protected by an end <br />section or a rock or concrete headwall. <br /> <br />PR-07 <br />2.05 - 27 - 5/03 <br />/~tyPRov~ <br />j~ z-I63 <br />
