Paragraph 2(b)(4)of the SOC states that the SOC shall terminate on a facility-by-facility basis on the later of the following dates: 180 days following completion of decanting; or 30 days following the approval of an amended groundwater Corrective Action Plan and/or Closure Plan as appropriate. Duke Energy completed decanting at each of the subject facilities and,per the terms of the SOC, submitted reports summarizing and characterizing the status of the seeps at the sites, and followed up with submittals of Seep Management Amendments to the proposed Groundwater Corrective Action Plan(CAP)Updates that had been previously submitted for each site. On July 8, 2021, the Department of Environmental Quality issued its conditional approval of the CAP Updates, including their seep management provisions. This event activated the provision regarding SOC termination within SOC S17-009 for each of the subject facilities, and this letter affirms that the SOC has been terminated for each of the subject facilities. As an interim measure, Duke Energy shall continue the monitoring and reporting of seeps established in the SOC until approval of the Surface Water Assessment Plans required in DEQ's conditional approvals of the CAP Updates.
