Topsoil overlying the clay material was stripped and temporarily stockpiled to one side of the bortow area to allow • removal of the clay. Excess non-clay material removed during the lagoon construction (which is not suitable for use in the compacted liner) was then be placed back into the cut formed in the borrow area, and the topsoil re-spread and re-seeded using the approved seed mixture. The bortow area lies within the small area exemption previously approved under CYCC's C-81-071 permit. This SAE utilizes a rock check dam and vegetative filters for the control of sediment, and these will serve to control this small amount of additional disturbance (approximately 0.8 acres, 4,000 CY of bortow material). See page 2.05-81 for a description of the SAE. The topsoil stockpile, approximately 4000 CY, was stabilized with the topsoil stockpile seed mixture. Likewise, the excess overburden was stabilized with this mixture. Two light duty roads, along with an access ramp from the existing employee parking lot, were constructed into the facility. The excess cut material was utilized to construct the roads and ramp. The roads were surfaced with aggregate to facilitate long term usage. An influent pretreatment structure was constructed on the influent line located upstream of the first treatment pond. The influent structure was of concrete construction with an inlet line, bar screen, flume, drying rack, and discharge structure. The total length of the inlet structure is approximately 18 feet in length and 4 feet wide. The concrete structure was approximately 8"thick. To protect the influent structure, a building approximately 16' x l2' x 9' was constructed on a steel I-beam frame. This construction allows for removal of the building in the event maintenance to the influent structure that is required. The wastewater flows through a buried 6" PVC line into the pond. The pond influent line is anchored to an inlet/outlet apron located on the bottom of the pond. Each of the three treatment ponds will have a set of inlet/outlet aprons. Six-inch PVC will be used to connect the ponds, and an overflow structure is located between each of the four ponds. The overflow structures have a 6" gate and are of • concrete construction. Each of the ponds has 3V:1H side slopes on the embankments/excavations. The ponds are l0 feet in depth, which allows for two feet of free board in each pond. The water level is two feet below the top of the berm. The effluent is chlorinated prior to discharging into the line leading over to the site 114 spring. The effluent is discharged in accordance with the terms of the CDOH discharge permit. The effluent can enter, via pumping from site 114, Twentymile's fresh water system. The water can be pumped from the spoil into the million-gallon tank. The water from the tank is pumped underground where is be used in the dust control systems located on the continuous miners, longwall mining equipment and associated equipment. A small percentage of the water will go out on the coal, while the remainder will flow into the underground sumps and eventually be discharged into Fish Creek from the existing Fish Creek dewatering borehole. The effluent will be discharged in compliance with the CDOH discharge permit. A controUchlorine contact building was constructed and utilized to control the aerators and administer the appropriate amount of chlorine into the effluent. This building is approximately 1G' x 12' x 9' and placed on a concrete pad. Power was brought into the site from the existing system located at Site l 14. Poles was placed between the ponds and the existing site and lines hung from the poles. The construction is in accordance with TCC's raptor-proof design. Permit Renewal No. 3 2.05-20 11/1/99 ~
