Run-off from the vent shaft pad does not go through a treatment facility such as a
sediment pond. Runoff from this pad will be filtered through one of two sediment
fences. Sediment fence #1 is 130-feet long with a tie back of 5-feet. Sediment
fence #2 is 30-feet long with a tie back of 5-feet. Design of the sediment fences is
presented in Volume I I I, Exhibit 8 beginning on page Exh-8 - 87. Flow will be routed
to the sediment fences with a series of berms as shown on Map 35.
Three or more gob vent boreholes GVBs are required over each longwall panel.
Additionally, exploratory holes will be drilled within the permit boundary. Run-off from
the related drill pads may not go through a treatment facility such as a sediment
pond. Run-off from the pads that does not report to a sediment pond will be filtered
through a sediment fence. Design of sediment fences for three drill pad
configurations are presented in Volume I I I, Exhibit 8 beginning on page Exh-8 -107.
The three typical drill pads are designed on a 3H:1 V slope, 5H:1 V slope and 10H:1V
slope. The typical sediment fence configuration, berms and ditches for the various
slopes and pad sizes are shown on Maps 36 and 36a. The following table lists each
drill hole and its design drill pad:
