Ditches 2 and 4 shall have a combined length of approximately 1 ,375 feet, and shall be <br /> constructed to the same specifications as ditches 3, 5, 6, 7 (Cross Section 1). Ditch 2 shall <br /> be constructed in coal refuse, while ditch 4 will be constructed in compacted colluvial <br /> materials. Upon completion of excavation, the channels will be broadcast seeded with the <br /> Sutey Diversion Mixture at a rate of sixty (60) pounds per acre. The seed will be provided by <br /> the PROJECT MANAGER. The entire channel length and width shall be lined with fabric <br /> which will consist of a natural material such as American Excelsior Corlex Double Net or <br /> equivalent having ultra-violet stabilized nets. The fabric shall be installed as per manufacturers <br /> specifications. <br /> Ditch 1 will be constructed in an existing diversion channel. Ditch 1 begins north of the Sutey <br /> Pile and traverses around the west and southern portions of the waste pile. At its <br /> downstream end, the diversion will pass under the pre-existing access road through an <br /> existing culvert. The access road adjacent to the diversion and refuse pile as well as the <br /> culvert will not be disturbed by construction operations. Ditch 1 will be approximately 3,300 <br /> feet in length, and will be trapezoidal in shape. The base of the channel will be no less than <br /> four (4) feet in width, with the side slopes excavated at a 2H:1 V slope. The total depth of <br /> the channel, as measured from the base of the channel to the crest of the side slopes shall <br /> be no less than 1 .2 feet. The width of the channel, as measured from crest to crest, shall be <br /> no less than 7.5 feet (Cross Section 2). Large rock encountered in the channel during <br /> excavation of Ditch 1 shall be removed from the channel and stockpiled near the bottom of <br /> Ditch 8 in a location to be specified by the PROJECT MANAGER. After excavation of the <br /> channel is completed, the entire length of the diversion will be broadcast seeded with the <br /> Sutey Diversion Mixture at a rate of sixty (60) pounds per acre. The seed will be provided by <br /> the PROJECT MANAGER. Ditch 1 shall be lined with fabric which will consist of a natural <br /> material such as coconut fiber sown between two ultra-violet stabilized nets (North American <br /> Green C125 flexible channel liner or approved equivalent). The fabric shall be installed as per <br /> manufacturers specifications. <br /> Ditch 8 will be constructed at the southeastern portion of the facility. Ditch 8 will primarily <br /> be located in an existing gravel-lined diversion. Ditch 8 will consist of a fabric-lined channel <br /> extending down the south-facing side of the facility for a length of approximately 800 feet. <br /> This ditch will be trapezoidal in shape, the base being no less than five (5) feet in width and <br /> the side slopes being no steeper than 2H:1 V. The width of the ditch as measured from crest <br /> to crest will be no less than nine (9) feet. The total depth of the ditch as measured from the <br /> base to the crest will be no less than 0.75 feet (Cross Section 3). Large rock encountered in <br /> the channel during excavation of Ditch 8 shall be removed from the channel, and stockpiled <br /> near the bottom of Ditch 8 in a location to be specified by the PROJECT MANAGER. Upon <br /> completion of excavation, the channel will be broadcast seeded with the Sutey Diversion <br /> Mixture at a rate of sixty (60) pounds per acre. The seed will be provided by the PROJECT <br /> MANAGER. Ditch 8 shall be lined with fabric which will consist of a natural material such as <br /> coconut fiber sown between two ultra-violet stabilized nets (North American Green C125 <br /> flexible channel liner or approved equivalent). The fabric shall be installed as per <br /> manufacturers specifications. <br /> 9 <br />
