On September 19, 2016, 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 March 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 181 ug/L 180 ug/L Barium 700 ug/L 43 ug/L 41 ug/L Boron 700 ug/L 68,900 ug/L 132,000 ug/L Cadmium 2 ug/L 14.7 ug/L 2.04 ug/L Chloride 250 mg/L 77 mg/L 110 mg/L Chromium 10 ug/L < 5 ug/L < 5 ug/L Copper 1 mg/L 0.287 mg/L 0.091 mg/L Fluoride 2 mg/L < 10 mg/L < 10 mg/L Iron 300 ug/L 128 ug/L 78 ug/L Lead 15 ug/L 3.56 ug/L 1.26 ug/L Manganese 50 ug/L 28,600 ug/L 29,800 ug/L Mercury 1 ug/L 0.09 ug/L 0.06 ug/L Nickel 100 ug/L 1,320 ug/L 188 ug/L Nitrate (as N)10 mg‐N/L 19 mg‐N/L 73 mg‐N/L pH 6.5‐8.5 SU 4.08 SU 4.21 SU Selenium 20 ug/L 63.9 ug/L 183 ug/L Silver 20 ug/L < 5 ug/L < 5 ug/L Sulfate 250 mg/L 6,400 mg/L 5,100 mg/L Temperature (°C)n/a °C 20.30 °C 20.39 °C TDS 500 mg/L 6,800 mg/L 6,600 mg/L Zinc 1 mg/L 1.69 mg/L 0.306 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.
