Per McGuire's 2016 NPDES Permit, the station may request removal of the Thallium monitoring requirement if twelve data points are obtained and no reasonable potential to exceed a water quality standard exists. Based on all twelve results being below the reporting limit of 0 2 ug/I, we are requesting that the Division remove this limit from our permit. The sampling data has been included as Attachment A to this correspondence. Please do not hesitate to contact Macrae Walters by phone at (980) 875-5635 or by email at Macrae.Walters(a)-Duke-Energy.com or Melanie Gardner at (919) 621-3177 or Melanie.

The DEAL is a North Carolina (NC) Certified Laboratory (certificate number 248) and holds certification in NC for the analysis of thallium in groundwater and wastewater via EPA method 200.8. All sample analyses utilized sufficiently sensitive test procedures approved under 40 CFR part 136 for the analysis of thallium. All sample analyses were less than (<) the DEAL analytical reporting limit of 0.2 ug/L. All analyses were below the McGuire Nuclear Station NPDES permit monthly average thallium limit of 0.24 ug/L, as well as, below the 0.24 ug/L EPA recommended water quality criteria for water supply waterbodies.
