Specifications include, but are not limited to: Continued development of the selected Quarry site will involve the adoption of an existing quarry floor with approximately 50,000 square feet of workable space. The current quarry face previously has been blasted and developed leaving behind high walls with interment benching. The exposed face stretches approximately 180 feet vertically from the quarry floor to the original ground surface. Future development will require the stripping of overburden from the area due south/west of the existing quarry face. All overburden shall be salvaged and placed on the graded waste disposal slope located north of the quarry floor. This existing disposal area must be graded to a 2:1 slope and all slope irregularities must be addressed prior to placement of overburden. Upon completion of overburden placement and track walking procedures, the slope shall be seeded and maintained until acceptable growth has occurred. For additional slope protection and storm water controls, the ARRC will require the construction of water retaining berms on the top and bottom grade breaks of the previous waste disposal area. Additional check berms will also be required near the midpoint of the slope serving as a means to breaking up concerted flows prior to flowing down the slope causing damage and erosion issues. This approximate 4 acre existing waste disposal area must also be seeded and stabilized where required and as per required in this ITB. After the completion of striping and removal of overburden, Production waste may be disposed of in the wooded area located to the east of the previous waste zone, as shown on the attached Site Map. Storm water runoff at the new waste disposal area must be controlled using methods similar to those listed above for the existing waste disposal zone. Production waste stockpiles/disposal areas shall not encroach on the quarry limits as shown in the Plans. Adequate room must be maintained to construct a berm at the base of the slope without encroachment of the Quarry Limits. The berm constructed at the base of the disposal area must tie into existing drainage structures and feed surface runoff into controlled outfall points for discharge. Water detention ponds may be allowed to control storm surge runoff. Swales and drainage areas must be graded and maintained at a minimum slope of ¼” per foot
