This pipeline would replace an existing <br />discharge pipeline that appears to be subject to clogging. Construction is anticipated <br />to take place during the upcoming Longwall move in May, during which period water <br />from the treatment pond is not required underground. Thus TCC will drain the pond <br />to allow construction. The pipeline will consist of a 12" PVC sewer line extending <br />approximately 50 from the treatment to the 115 drainage channel. <br />TCC also requests approval for the installation of an 18" culvert, extending from a <br />drainage sump constructed along bottom of the Pond B access road, to an existing <br />collection basin located immediately south of the access road. The Pond B access road <br />had been an on-going concern during wet periods when runoff erosion could discharge <br />fines into a vegetative area along Foidel Creek. A soil berm located between the access <br />road and Foidel Creek will prevent future discharge into the creek. A sump and <br />culvert located at the base of the road will direct runoff into the existing collection <br />basin that eventually drains to Pond B. <br />The proposed FCBH pipeline and Pond B sump and culvert are shown on Map 24 (Map <br />2 of 3, and 1 of 3, respectively).
