. 2.05.3 <br />Run-off from the vent shaft pad does not go through a treatment facility such <br />as a sediment pond. Run-off from this pad will be filtered through one of <br />two sediment fences. Sediment fence #1 is 130-feet long with a tie back of <br />5-feet. Sediment fence #2 is 30-feet long with a tie back of 5-feet. Design <br />of the sediment fences is presented in Volume III, Exhibit 8 beginning on <br />page Exh-8 - 87. Flow will be routed to the sediment fences with a series of <br />berms as shown on Map 35. <br />Up to three gob vent boreholes GVBs are required over each longwall panel. <br />Additionally, exploratory holes will be drilled within the permit boundary. Run- <br />offfrom the related dril{ pads may not go through a treatment facility such as <br />a sediment pond. Run-off from the pads that does not report to a sediment <br />pond will be filtered through a sediment fence. Design of sediment fences <br />for three drill pad configurations are presented in Volume III, Exhibit 8 <br />beginning on page Exh-8 -107. The three typical drill pads are designed on <br />a 3H:1 V slope, 5H:1 V slope and 10H:1 V slope. The typical sediment fence <br />configuration, berms and ditches for the various slopes and pad sizes are <br />shown on Maps 36 and 36a.. <br />• The following table lists each drill hole and its design drill pad. <br />I• <br />Drill H oles <br />Ori final Ground S lo a Inform ation <br />Identifier Hote Name Sloe Identifier Hole Name Slo e <br />063 VB-D-26 10:1 078 VB-WD-1A 10:1 <br />041 VB-D-7A 3:1 050 VB-WD-2C 5:1 <br />042 GVB-D-SA 3:1 080 GVB-WD-1B 10:1 <br />044 VB-D-4B 5:1 083 eo-TCH-01 10:1 <br />051 VB-WD-3C 5:1 084 eo-TCH-02 10:1 <br />052 VB-WD-36 3:1 085 eo-TCH-03 5:1 <br />053 VB-WD-2B 3:1. 087 VB-D-BC 10:1 <br />054 VB-WD-3A 10:1 090 VB-D-BB 5:1 <br />055 VB-WD-2A 10:1 092 VB-D-9B 3:1 <br />059 VB-D-4C 10:1 094 VB-D-8A&9A 3:1 <br />060 VB-D-5B 5:1 096 IP-99-16 10:1 <br />061 VB-D-5C 10:1 102 IP-99-11 3:1 <br />062 VB-D-6C 5:1 102 IP-99-11 3:1 <br />064 GVB-D-6A 5:1 120 KM-3 3:1 <br />065 VB-D-68 3:1 129 P-B-Bum-22 10:1 <br />066 VB-D-7B 5:1 130 P-B-Bum-23 10:1 <br />068 DH-57 10:1 131 P-TC-03-01 10:1 <br />070 DH-58 10:1 132 P-TC-03-02 10:1 <br />075 VB-D-7C 10:1 133 P-TC-03-03 10:1 <br />077 VB-D-SD 5:1 134 - 137 P-TC-03-04 - 07 10:1 <br />TR-2 8 2.05 - 34 - <br />APPRoveD q~s~os <br />6/03 <br />
