Alexander Livnat, Ph.D. 12/18/2014 This Is the Fourth out of Five Volumes Alexander Livnat, Ph.D. 12/18/2014 This is the fourth out of five volumes describing EPA’s current state of knowledge of CCR damage cases. This volume comprises 22 damage case-specific modules. Each module contains background information on the host power plant, type and design of the CCR management unit(s), their hydrogeologic setting and status of groundwater monitoring system, evidence for impact, regulatory actions pursued by the state and remedial measures taken, litigation, and rationale for the site’s current designation as a potential damage case in reference to pre-existing screenings. Ample footnotes and a list of references provide links to sources of information. IIb. Potential CCR Damage Cases Part II (Cases 33-55) December 2014 IIb.

Background and Description: The Belews Creek Steam Station, with two-unit 2,240 MW coal-fired generation capacity, was constructed in 1974 on the Dan River in the Piedmont area of North Carolina.2 The Belews Creek Steam Station has three landfills: the unlined Pine Hall Road Fly Ash Landfill;3 Craig Road Fly Ash Landfill;4 FGD Residue Landfill; 5 an unlined ash impoundment, 6, 7, 8 a chemical washdown pond, and a cooling lake (Belews Lake).9 With the exception of the Pine Hall Road Fly Ash Landfill, which was closed in 2007 with an NC DENR-approved Closure Plan, all the other disposal units are 1 In July 2012, Duke Power and Progress Energy merged into Duke Energy Carolinas, LLC. 2 http://www.duke-energy.com/power-plants/coal-fired/belews-creek.asp 3 The Pine Hall Landfill (NC Permit #85-03) was established in Dec. 1984 and closed in Dec. 2007; it occupied 40- acres, has a synthetic cap plus 24” of soil and drainage layer (completed in Dec. 2008); 13 groundwater monitoring wells and two background wells (NC DENR’s comment to the October 2011 NODA: EPA-HQ-RCRA-2011-0392- 0267). 4 The Craig Road Fly Ash Landfill (NC Permit #85-04) started receiving ash in Feb. 2008, Phase 1 occupies 31- acres with overall height of 100 feet, 10 groundwater monitoring wells, and a geosynthetic liner and leachate collection system: NC DENR’s comment to the October 2011 NODA: EPA-HQ-RCRA-2011-0392-0267 and http://www.smeinc.com/belews-creek-steam-station-ash-landfill (accessed Online July 2012). Duke Energy has recently applied for expansion of this landfill; USACE Public Notice, December 15, 2011: http://www.saw.usace.army.mil/wetlands/notices/2011/Public%20Notice%20Supplement%20201100972.pdf (accessed Online July 2012). 5 The FGD Residue Landfill (NC Permit #85-05) was established in Jan. 2008, Phase 1 occupies 22.6-acres with overall height of 100 feet, 12 groundwater monitoring wells, and composite-lined with leachate collection system. The status of both the Pine Hall and FGD waste unit liners is from NC DENR comment to the proposed CCR rule docket: EPA-HQ-RCRA-2009-0640-9282 and NC DENR’s comment to the October 2011 NODA docket: EPA-HQ- RCRA-2011-0392-0267. According to http://www.wspgroup.com/en/Welcome-to-WSP-SELLS/Sectors/All/project- list-wspsells/Belews-Creek-Steam-Station/ (accessed Online July 2012), the FGD Landfill is underlain with a composite liner system with a 60-mil HDPE geomembrane over a geosynthetic sodium bentonite liner. 6 The unlined impoundment (also, ‘Basin’) was established in 1974; it occupies an area of about 342-350 acres, and has a total capacity of about 20.3 million cubic yards volume. The Ash Basin Dike at the Belews Creek Steam Station is an approximate 2,000 foot long and 140 foot high earthen dike that is located on a tributary to the Dan River locally referred to as Little Belews Creek. CCR is discharged into the southern reaches of the impoundment via sluice pipe lines. Water within the impoundment is currently discharged through the Ash Basin Tower by two stop log weirs on the west side of the embankment: Duke Energy (2009), CHA/Lockheed Martin (2009) and Duke Energy reviews safety at Belews Creek, January 19, 2009 (accessed Online July 2012): http://www.arizonaenergy.org/News_09/News_Jan09/Duke%20Energy%20reviews%20safety%20at%20Belews%2 0Creek.htm 7 CHA/Lockheed Martin (2009). 8 http://www.epa.gov/osw/nonhaz/industrial/special/fossil/surveys/duke-belews.pdf (accessed Online July 2012). 9 CHA/Lockheed Martin (ibid), Section 1.3.1 and Fig. 2B. Constructed between 1972 and 1974, this pond is located south of the Ash impoundment and is used every 3 to 4 years. The overflow from this pond discharges into the Ash impoundment. The Ash impoundment pool is located at the toe of the chemical washdown pond dike. The pond does not directly receive CCR, only chemical cleaning water and the subsequent rinses resulting from the washdown and maintenance of the condensate and steam side of the boiler tubes. Completed in 1973, Belews Lake has a surface area of 3,863 acres and a shoreline of approximately 88 miles. It is impounded by a rolled earth fill dam with a concrete spillway across Belews Creek:http://www.duke-energy.com/lakes/facts-and-maps/belews-lake.asp

    Power From the Valley: Nuclear and Coal in the Postwar U.S. Dissertation Presented in partial fulfillment of the requirements for the Degree Doctor of Philosophy in the Graduate School of the Ohio State University By Megan Lenore Chew, M.A. Graduate Program in History The Ohio State University 2014 Dissertation Committee: Steven Conn, Advisor Randolph Roth David Steigerwald Copyright by Megan Lenore Chew 2014 Abstract In the years after World War II, small towns, villages, and cities in the Ohio River Valley region of Ohio and Indiana experienced a high level of industrialization not seen since the region’s commercial peak in the mid-19th century. The development of industries related to nuclear and coal technologies—including nuclear energy, uranium enrichment, and coal-fired energy—changed the social and physical environments of the Ohio Valley at the time. This industrial growth was part of a movement to decentralize industry from major cities after World War II, involved the efforts of private corporations to sell “free enterprise” in the 1950s, was in some cases related to U.S. national defense in the Cold War, and brought some of the largest industrial complexes in the U.S. to sparsely populated places in the Ohio Valley. In these small cities and villages— including Madison, Indiana, Cheshire, Ohio, Piketon, Ohio, and Waverly, Ohio—the changes brought by nuclear and coal meant modern, enormous industry was taking the place of farms and cornfields. These places had been left behind by the growth seen in major metropolitan areas, and they saw the potential for economic growth in these power plants and related industries.
