8. Small Area Exemptions <br />As of the Permit Revision 06, one Small Area Exemption exists in the permit area. This is the <br />disturbed topsoil stripping area in advance of the mining pit. The small area exemption is <br />designed to meet or exceed effluent requirements according to Rule 4.05.2 and was <br />originally approved for the entire permit area in the year 2000 under Permit Amendment PR- <br />5. The designs for this exemption are shown in Attachment 2.05.3(3) -7 Small Area <br />Exemptions. <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 />these roads meet the criteria for grades, compaction, drainage, etc. All haul roads at the site <br />are nearly flat in grade and have minimal fills (less than 2 feet high) and basically no cuts. <br />(Revised .tune 2010) 2.05.3(3) -20 <br />
