Reeder Governor Director November 14, 2013 Mr. David Mitchell — Director Environmental - Air & Waste/CCR Duke Energy Progress, Inc. 526 South Church Street Mail Code EC13K Charlotte, NC 28202 Dear Mr. Everett: Natural Resources John E. Skvada, III Secretary Subject: Permit No. W00000020 Duke Energy Progress, Inc. Distribution of Ash Residuals Statewide The Division of Water Resources (Division) has updated its database to reflect the company name change request from Carolina Power & Light Company, d/b/a Progress Energy Carolinas, Inc. (Progress Energy) to Duke Energy Progress, Inc. received May 6, 2013. Based on discussion from a September 30, 2013 meeting with Duke Energy Progress, Inc. representatives, additional information related to the structural fill projects and groundwater monitoring requirements is included with this letter. The Division believes that the current permit contains language that is inconsistent with current North Carolina Administrative Code, and further clarification is needed to ensure that Duke Energy Progress is aware of the expectations of their distribution program. The concerns and expectation expressed in our letter to Duke Energy Corporation dated April 21, 2010 (attached), can be expanded to include permit W00000020 as well. It is the Division's intent to include with the next issued permit an accounting of the structural fill sites and incorporation of the requirements of 15A NCAC 02T .1204. The attached table provides a listing of the three permitted structural fill projects Duke Energy Progress has reported to the Division to -date, their CCP sources for each site, the estimated size, groundwater monitoring well names, project status, and other locational information. A second table includes the monitoring requirements established by the Ashville Regional Office pursuant to Section III. 1. of the subject permit. To ensure that proper operation and maintenance practices are occurring at the structural fill sites, please update your operation and maintenance plan as need to include at a minimum visual inspection of all slopes underlain by ash fill, monitoring well structural integrity, drainage pathways, and cover crop. It is expected that Duke Energy Progress will report and repair any signs of erosion and breaches in fill and liner, report any day -lighting of OCPs, keep slopes clear of woody debris, maintain drainage features, maintain cover crop, etc. WATER PERMITTING SECTION 1636 Mail Service Center, Raleigh, North Carolina 27699-1636 Location: 512 N.
