14 Coal Ash Ponds: Impoundments created near the power plant to store or dispose of ash from combustion of coal. Ash solids settle, leaving water at the surface to be recycled or discharged. Pond at Mountain Island Lake Pond at Buck Steam Plant

15 Plant and Coal Ash Pond Locations. Green: Retired Plant Sites. Blue: Operating Plant Sites

16 Inventory of Duke Energy Coal Ash Ponds in North Carolina 32 Total Ponds 7 Active Receiving Ash 28 Inactive Not Receiving Ash 107,889,000 Tons of Ash

17 Dan River Spill

18 High, High* Hazard Failure or mis-operation of dam will probably cause loss of human life. Significant Hazard Failure or mis-operation of dam results in no probable loss of human life, but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns

19 Coal Ash Management Act Senate Bill 729 Passed August 20 th, Part Bill Dan River Spill, Impetus for Legislation Temporarily bans Duke from raising consumers’ rates to pay for clean-up until January 2015 Only requires immediate removal of coal ash from 4 of the 14 sites Asheville, Riverbend, Dan River, and Sutton Key Provisions Construction/ Expansion of Coal Ash Ponds is Banned as of October 1 st Duke must test private wells, and replace contaminated drinking-water supplies for residents End of 2015, DENR will divide coal ash sites into high, intermediate, and low risk categories High risk sites must be excavated and placed in a lined landfill by the end of 2019 Intermediate sites by 2024 Fly ash must be converted to dry – End of 2018 Bottom ash Dry – End of 2019 State will impose a 0.03% fee on NC revenues with coal ash sites, utility may not recover it by increasing retail rates

20 Regulations EPA CCBs are currently considered exempt wastes under the RCRA EPA is proposing to regulate for the first time coal ash to address the risks Two possible options, both fall under the RCRA Subtitle C – Special wastes subject to regulation Subtitle D – Section for non-hazard wastes Appalachian Voices v. Gina McCarthy January, 29, U.S. District Court of Columbia ruled EPA has mandatory duty to review coal ash under RCRA Regulation to be finalized: December 19, 2014 State DWR - Division of Water Resources Wastewater discharged from Coal Ash ponds Shares responsibility for the regulation of coal combustion residuals with the Division of Waste Management Regulates beneficial uses of CCBs DWM Regulates fly ash landfills Regulation of CCBs and residuals DEML – Division of Energy, Mineral and Land Resources Regulates Dam safety for the pond structures NPDES – National Pollutant Discharge System Division of DWR, regulates ash ponds through permits
