On March 8, 2017, leachate samples were collected from the leachate collection system. The samples were collected by Duke Energy personnel. A summary of sampling results can be found in Table 1. As noted in the table, 15 NCAC 2L .0202 standards are provided for reference only. The parameters tested are not bound by state groundwater or surface water standards. The leachate is conveyed to the station’s ash impoundment, which discharges via a NPDES permitted outfall. All laboratory analytical and field results are provided as Attachments 1 and 2, respectively. Duke Energy personnel sample landfill leachate at Allen Steam Station’s RAB Ash Landfill semi- annually during March and September. The next landfill leachate sampling event will occur during September 2017 with documentation to follow. If you have any questions or concerns, please contact me at 704-382-4761 or at Sean.DeNeale@duke-energy.com Sincerely, Sean DeNeale, Engineer III Environmental Services Cc: Mr. Scott Harris – Allen Steam Station Mr. Randy Gantt – Allen Steam Station Ms. Kimberlee Witt – Duke Energy Corporation Arsenic 10 ug/L 184 ug/L 131 ug/L Barium 700 ug/L < 50 ug/L < 50 ug/L Boron 700 ug/L 68,100 ug/L 113,000 ug/L Cadmium 2 ug/L 16.1 ug/L 3.16 ug/L Chloride 250 mg/L 86 mg/L 120 mg/L Chromium 10 ug/L < 50 ug/L < 50 ug/L Copper 1 mg/L 0.474 mg/L 0.188 mg/L Fluoride 2 mg/L < 10 mg/L < 10 mg/L Iron 300 ug/L 235 ug/L < 100 ug/L Lead 15 ug/L 3.76 ug/L < 1 ug/L Manganese 50 ug/L 34,100 ug/L 30,000 ug/L Mercury 1 ug/L 0.07 ug/L 0.06 ug/L Nickel 100 ug/L 1,690 ug/L 299 ug/L Nitrate (as N)10 mg‐N/L 24 mg‐N/L 66 mg‐N/L pH 6.5‐8.5 SU 4.09 SU 4.25 SU Selenium 20 ug/L 75.7 ug/L 282 ug/L Silver 20 ug/L < 50 ug/L < 50 ug/L Sulfate 250 mg/L 7,100 mg/L 6,200 mg/L Temperature (°C)n/a °C 19.82 °C 19.99 °C TDS 500 mg/L 4,800 mg/L 5,100 mg/L Zinc 1 mg/L 2.33 mg/L 0.518 mg/L NOTE:  15A NCAC 2L .0202 Standards are provided only for reference.  Analytical results  are for landfill leachate, which is NOT bound by state groundwater or surface water  standards.  Landfill leachate is conveyed to the station's ash impoundment, which  discharges via a NPDES permitted outfall.
