The construction of the french drain was approved by the <br />Division in Minor Revision No. 185. The purpose of the french drain was to collect springs that <br />were emanating from two thin coal seams. The french drain has been successful in collecting the <br />water. <br />Following the construction of the french drain it was observed that there are two more coal seams <br />that are located below the bottom elevation of the french drain. MCC plans to construct an <br />additional french drain to collect the water that is emanating from these coal seams. The french <br />drain will be constructed as the french drain in Minor Revision No. 185 was constructed. A <br />trench, approximately 10 feet deep and 100 feet long will be lined with a 30 ml PVC liner and <br />gravel placed in the trench. The french drain will be located approximately 40 to 50 feet down <br />slope of the first drain. It will daylight on the west end of the cutslope and connect to the eight <br />inch surface ADS pipe, which was installed during the construction of the first french drain. MCC <br />is planning to begin this work this week. <br />Please call ifyou have any questions. <br />Permitting Specialist <br />cc: Norm Every <br />ra~~sl,.da <br />
