2.05.3 <br />Run-off from the Terror Creek shaft site does not go through a treatment facility <br />such as a sediment pond (SAE 16). Run-off from this pad will be filtered through a <br />25 -foot long sediment fence, straw log or straw wattle. Design of the sediment <br />fence is presented in Volume III, Exhibit 8 beginning on page Exh-8 - 238. <br />Run-off from the material storage area located below drainage area E and west of <br />pond C does not go through a treatment facility such as a sediment pond. The <br />material storage area is located north of the haul road. Run-off from the material <br />storage area and adjacent haul road is directed to ditch D -E1. Sediment traps are <br />installed in ditch D -E1 as shown on Map 21-1. The sediment traps will be straw <br />bales, silt fences, straw logs, straw wattles or other approved devices. The <br />sediments traps will slow and remove sediment from the run-off from the material <br />storage area and haul road. There is no SAE number or design associated with this <br />area. <br />The vent shaft pad located in Freeman Gulch was covered by a massive slide. It is <br />no longer monitored or maintained. Design of the sediment fences was presented in <br />Volume III, Exhibit 8 beginning on page Exh-8 - 87. <br />Three or more gob vent boreholes GVBs are required over each longwall panel. <br />Additionally, exploratory holes will be drilled within the permit boundary. Run-off <br />from the related drill pads may not go through a treatment facility such as a <br />sediment pond. Run-off from the pads that does not report to a sediment pond will <br />be filtered through a sediment fence, straw logs or straw waddles. Straw logs will be <br />a minimum six inches in diameter. Design of sediment fences for drill pad <br />configurations are presented in Volume III, Exhibit 8 beginning on pages Exh-8-107 <br />and Exh-8-223. Refer to page Exh-8-106i for a discussion of the straw log <br />substitute for silt fences. The three typical drill pads are designed on a 3H:1 V slope, <br />5H:1 V slope and 10HA V slope. The typical sediment fence configuration, berms <br />and ditches for the various slopes and pad sizes are shown on Maps 36, 36a and <br />36b. The following table lists each drill hole and its design drill pad: <br />A comprehensive listing of all underground openings, methane drainage wells, <br />exploration holes, wells, shafts and portals follows beginning on page 2.05-45i. <br />MR -168 2.05-43- 11/14 <br />
