• 8. Small Area Exemptions <br />As of the Mid Term Review of 2006, 5 Small Area Exemptions exist or are planned in the <br />permit area. Four of these are small areas which cannot drain to the sediment pond system <br />due to lower elevation of these areas. The final one is the disturbed topsoil stripping area in <br />advance of the mining pit. All small area exemptions are designed to meet or exceed efFluent <br />requirements according to Rule 4.05.2 and were originally approved for the entire permit <br />area in the year 2000 under Permit Amendment PR-5. The designs for these exemptions are <br />shown in Attachment 2.05.3(3)-7 Small Area Exemptions. The areas are also shown on Map <br />2.05.3(3)-1. No small area exemptions exist on the New Horizon #1 site. <br />9. Discharge Structures <br />Discharge from the sedimentation pond, diversions and pit dewatering will be controlled by <br />energy dissipators, riprap channels, and other means or devices, where necessary, to <br />reduce erosion, to prevent deepening or enlargement of stream channels, and to minimize <br />disturbance of the hydrologic balance. Discharge structures will be designed according to <br />• standard engineering design procedures. <br />10. Transportation Facilities <br />Haul Roads <br />The following describes the design and construction of haul roads at the New Horizon Mine. <br />There will be three separate haul roads which will be utilized throughout the mining of the <br />New Horizon Mine. Please see Map 2.05.3(3)-8 for full detail on the road alignment and <br />profiles for all haulage roads. The names of the four haulage roads which will be utilized can <br />be seen as Northeast Perimeter Haul Road, Southwest Haul Road, and BB West Haul Road. <br />Map 2.05.3(3)-8 additionally shows typical construction cross sections of the haulage roads <br />and shows a table which details the widths of the haulage roads. The Northeast Perimeter <br />Haul Road is as built; the other 2 haul roads are designed widths which will be constructed <br />as mining progresses west of 2700 Road. <br />The Southwest Haul Road and BB West Haul Road are haul roads within the disturbed area <br />and for this reason do not need to meet the design criteria of Rule 4.03.1(3). Nevertheless, <br /> <br />(Revised July 2006) 2.05.3(3)-26 <br />
