Wetland delineation report is attached to the Stormwater Management Report, Appendix D-3. 6. Wastewater Treatment Will this facility wash mined materials? ❑XYes El No Will discharges of process wastewater treatment systems occur(including possible recycle system overflows) ❑XYes(please describe) Collected PAG contact water and concentrator plant process water will be treated at the water treatment plant (WTP). Treated water will be reused in the process, and the remainder and excess recovered water will be transferred to WSB-1 for storage. The recovered water from the WTP will be comingled with contact stormwater and mine pit dewatering in WSB-1. WSB-1 discharge will go through the WSB-1 impoundment dam (at Outfall 003) into an unnamed tributary to Kings Creek. El No Will this facility employ chemical additives to flocculate suspended solids? ❑X Yes(specify name/manufacturer/quantity of daily use) See attached chemical additives list El No Note: please visit: https://files.nc.gov/ncdeg/Water+Quality/Environmental+Sciences/ATU/PAM8 30 18.pdf for list of approved PAMS Will any of the wastewater treatment facilities at this mine overflow only during rainfall events that exceed the 10-yr, 24-hr rainfall event? ❑Yes(specify which systems) ❑X No Are wastewater treatment facilities(including recycle systems)planned in the 100-year flood plain? ❑Yes ❑X No Wastewater Treatment Alternative Review as required by 15A NCAC 2H.0105(c)(2) Types of wastewater this mine site will discharge: ❑X Mine Dewatering ❑X Process Wastewater Water treated at the WTP will have two discharges, reverse osmosis brine and treated water. No brine will be discharged to surface waters. The brine will be transported offsite to an approved facility for disposal. Treated water will be diverted to WSB-1 where water will be stored and reused for processing needs. Water in WSB-1 will be comingled from multiple sources including treated water and stormwater. Water in excess of recycling needs that meets surface water standards will then be discharged to an unnamed tributary to Kings Creek. Types of wastewater considered for this alternative review: ❑X Mine Dewatering ❑X Process Wastewater Page 3 of 11 Are there existing sewer lines within a one-mile radius? ❑X Yes ❑Wastewater treatment plant will accept wastewater ❑Is feasible to connect(explain) ❑X Is not feasible to connect(explain) -Pipeline connection to the TJ Ellison WTP is possible, but nearly 500 percent more expensive than the next considered alternative, rendering this alternative infeasible. -Water discharged from WSB-1 will only require sediment control prior to discharge. It is not practical for the City of Kings Mountain to process high volumes of water for only sediment control. ❑Wastewater treatment plant will not accept wastewater(please attach letter documenting this) ❑No Are you already proposing a closed-loop recycle system(CLRS) Water will be withdrawn from WSB-1 as part of mine that meets design requirements of 15A NCAC 2T.10000? operations to provide water for process makeup, raw water supply, and dust suppression.WSB-1 has been designed to provide adequate water supply to the mine even during severe ❑Yes,for dewatering drought conditions and provide for storage of contact water if ❑Yes,for process wastewater upset conditions prevent release of contact water. ❑Yes,for both ❑No,this option is technologically feasible(explain) ❑No,this option is not technologically feasible(explain) ❑X No,this option is otherwise feasible(explain) ❑No,this option is otherwise not feasible(explain) What is the feasibility of building a CLRS compared to direct surface water discharge? Surface or Subsurface Disposal System ❑A surface or subsurface disposal system is technologically feasible(explain) ❑A surface or subsurface disposal system is not technologically feasible(explain) ❑A surface or subsurface disposal system is otherwise feasible to implement(explain) OA surface of subsurface disposal system is not otherwise feasible to implement(explain) What is the feasibility of employing a subsurface or surface discharge as compared to a direct discharge to surface waters? Subsurface is not feasible because the water discharged is desirable for use in operations. Furthermore, Albemarle does not own sufficient land to consume discharged water as land application. The land is generally unsuitable for land application due to reclaimed, low infiltration waste rock piles and steep slopes. Direct Discharge to surface waters is the most environmentally sound alternative to all reasonably cost-effective options for the wastewaters being considered? ❑X Yes El No If this review included all wastewater discharge types,would excluding some types make any of the above non-discharge options feasible for some the wastewaters? ❑Yes ❑X No 7.
