(Golder) is submitting this 14-Day Notification as required by North Carolina Solid Waste Management Regulation (NCSWMR) 15A North Carolina Administrative Code (NCAC) 13B .1633(c)(1). The 14-Day Notification of Groundwater Protection Standard Exceedance(s) form is included as Attachment 1. Tables 1 through 3 (shown below) summarize the NC Appendix I constituents that were detected at concentrations above their respective Solid Waste Section Reporting Limits (SWSLs) and NC 2L Groundwater Standards or Solid Waste Section Groundwater Protection Standards (SWS GPSs) during the first semi-annual water quality monitoring event of 2017 conducted at the closed unlined landfill, the closed Subtitle D landfill, and the active Subtitle D landfill at the above-referenced facility between March 5, 2017, and April 6, 2017. The laboratory certificates-of-analyses are included as Attachment 2. It is noted that the Closed Unlined Landfill is in corrective action for volatile organic compounds (VOCs); therefore no notifications for groundwater standard exceedances for VOCs are required for this facility. Table 1: 14-Day Notifications for the Closed Unlined Landfill Constituent: Location: Result (µg/L): SWSL (µg/L): NC2L or SWS GPS (µg/L): Proposed GPS (µg/L): Barium OW-3 1200 700 100 12000 Cobalt OW-3 17.4 10 1 800 Notes: µg/L = micrograms per liter The proposed GPSs are based on statistical analyses presented in the 14-Day Notification and Alternate Source Demonstration, dated November 3, 2016, for the second semi-annual water quality monitoring event of 2016.
