❑ Yes 0 No
Will discharges of process wastewater treatment systems occur(including possible recycle system overflows)
❑ Yes(please describe)
A No
Will this facility employ chemical additives to flocculate suspended solids?
❑ Yes(specify name/manufacturer/quantity of daily use)
M 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)
❑ No
Are wastewater treatment facilities (including recycle systems) planned in the 100-year flood plain?
❑ Yes ❑■ No
Wastewater Treatment Alternative Review as required by 15A NCAC 2H.0105(c)(2) N/A
Types of wastewater this mine site will discharge: 0 Mine Dewatering ❑ Process Wastewater
Types of wastewater considered for this alternative review: Mine Dewatering ❑ Process Wastewater
Are there existing sewer lines within a one-mile radius?
❑ Yes
❑ Wastewater treatment plant will accept wastewater
❑ Is feasible to connect(explain)
❑ Is not feasible to connect(explain)
❑ Wastewater treatment plant will not accept wastewater(please attach letter documenting this)
❑■ No
Are you already proposing a closed-loop recycle system (CLRS)that meets design requirements of 15A NCAC 2T.10000?
❑ Yes,for dewatering
❑ Yes,for process wastewater
❑ Yes,for both
❑ No,this option is technologically feasible(explain)
Direct surface water discharge is only option to
No,this option is not technologically feasible(explain) effectively lower the water level in the pit.
❑ No,this option is otherwise feasible(explain)
Direct surface water discharge is only option to
*No,this option is otherwise not feasible (explain) effectively lower the water level in the pit.
What is the feasibility of building a CLRS compared to direct surface water discharge?
