Biological Assessment to Determine Impacts of Selenium Pollution from Coal Ash Wastewater Discharges on Fish Populations in Lake Sutton, NC
Biological Assessment to Determine Impacts of Selenium Pollution From Coal Ash Wastewater Discharges on Fish Populations in Lake Sutton, NC Prepared by A. Dennis Lemly, Ph.D. 215 Sapona Road, Lexington NC 27295 Prepared for Southern Environmental Law Center Chapel Hill Office 601 West Rosemary Street, Chapel Hill NC 27516 November 5 2013 1 Background Progress Energy owns and operates Lake Sutton NC as a cooling reservoir for the L.V. Sutton Steam Plant, a coal-fired electric generating facility. The lake is used as a disposal site for coal ash wastewater from the power plant and it is also open to the public for fishing. The NC Division of Inland Fisheries and/or Progress Energy have monitored fish populations and chemical pollution from coal ash in Lake Sutton since the late 1980’s (NCDIF 2010, 2013). Since that time, a substantial amount of information has resulted showing that Lake Sutton is polluted by the trace element selenium. Selenium is a well-documented contaminant in coal ash wastewater and it can cause developmental abnormalities and reproductive failure in fish and wildlife (Lemly 2002a). Although monitoring results indicate that the concentrations of selenium in fish equal or exceed diagnostic toxic levels there has been no detailed biological investigation to determine if impacts are actually occurring. The Southern Environmental Law Center commissioned this study to answer that question. The assessment method used was developed by Dr. Lemly through his work on other selenium-polluted lakes in NC and is published in the peer-reviewed scientific literature (Lemly 1993, 1997a). It consists of examining young fish for the presence of selenium-induced defects and then applying an assessment index to evaluate impacts on the Lake Sutton fish community. -

ABSTRACT MORT, SANDRA AMISS. Mass Spectrometric Methods for the Determination of PCB Congeners for Environmental Risk Assessment. (Under the direction of Dr. W. Gregory Cope and Dr. Damian Shea). Our research provides important advances in the evaluation of alternative, cost effective analytical systems for polychlorinated biphenyl (PCB) risk assessment of environmental matrices. This type of evaluation has previously been limited by a reluctance on the part of regulators, site owners and investigators, to specify U.S. EPA Method 1668, the 209-PCB congener analysis recommended for environmental media, including biota, water, sediments and soils. U.S. EPA Method 1668 specifies a high-resolution gas chromatography / high- resolution mass spectrometry detection system (HRGC/HRMS) that is of limited availability in both federal and state environmental regulatory agency laboratories, as well as in contract environmental laboratories. This leads to a high cost for 209-PCB congener analysis and a reluctance to require it for environmental risk assessment. While additional validation is needed, this research indicates that low resolution tandem mass spectrometry (LRMSMS) gas chromatography systems provide adequate PCB congener resolution and detection sensitivity to provide robust data for environmental risk assessment of weathered (i.e., degraded) PCB contamination. Our results provide additional support for the need for 209-PCB congener- specific analyses to thoroughly assess the environmental risks associated with abiotic weathered PCB sources, or to define food web component specific PCB burdens and predator, and ultimately, human risks. Based on observations of waterbody, species and trophic guild specific PCB congener profiles in fish collected from four waterbodies of the Yadkin-Pee Dee River system of North Carolina, alternative human health risk assessment methods suggest that some North Carolina sub-populations ingesting fish from the four Yadkin-Pee Dee waterbodies may not be adequately protected from the potential for increased cancer risks by the N.C. -
Water Supply & Wastewater
Piedmont Triad Climate Resiliency Tool Kit Water Supply & Wastewater Introduction Water is a scarce natural resource in the Piedmont region. As the Piedmont Triad continues to grow and develop, and the demand for potable water increases, it has become increasingly important to monitor the surface water capacity available to fulfill our regional water demand. Short-term solutions to water issues are generally quick and necessary steps in reaction to immediate concerns. However, a long-term planning approach will better prepare local governments for the unique challenges facing our region. Investment in a deeper understanding of the complex and challenging political, regulatory, and environmental issues surrounding water supply will help guide decision-makers to consider future ramifications of options in resource planning. This assessment of current and future (20-50 years) water resource needs and wastewater treatment plant capacity includes the 12-county Piedmont Triad Regional Council (PTRC) Region (Alamance, Caswell, Davidson, Davie, Forsyth, Guilford, Montgomery, Randolph, Rockingham, Stokes, Surry, and Yadkin Counties). Water supply and wastewater capacity are assessed within the context of surface water availability, projected population growth, geography, current laws and regulations, water quality, and patterns of water use (water conservation and water reuse). Background Drinking water comes from two primary sources, surface water or groundwater. Surface water is the water found above ground in the form of rainwater runoff, streams, rivers, lakes and reservoirs. Groundwater is unseen and deep in the ground saturating porous sandy soils or fractures of bedrock. Surface water and groundwater affect each other. Groundwater comes to the surface (springs) and can help replenish surface water. -
Hydropower in Central North Carolina: the Battle for the Yadkin
Hydropower in Central North Carolina: The Battle for the Yadkin Eric Anderson Introduction Alcoa and North Carolina have been locked in a licensing dispute for the better part of a decade. At stake is control over a 38-mile segment of the Yadkin River, four dams, and the profits earned by selling the electricity generated by those dams. Alcoa is seeking renewal of its operating license for its four dams on the Yadkin River. In 1958, the Federal Power Commission granted Alcoa a 50-year operating license for the dams. At the time, Alcoa was a major employer in Stanly County where it operated an aluminum smelting complex. That smelting complex is now closed and Alcoa is no longer a major employer in North Carolina. The state does not support allowing Alcoa to operate these dams for 50 more years without substantial economic benefits flowing back to the people of North Carolina in return. The dispute raises issues of private property rights, ownership of submerged land, management of public waterways for the public benefit, and the obligations owed by private corporations to the public in exchange for the use of a public resource like the Yadkin River. This last issue is of particular significance when a corporation moves its operations from one location to another, yet continues to benefit from a public resource in its former location. This is the context in which the dispute between Alcoa and North Carolina arises. History of Yadkin Dams Alcoa began development of its Badin, NC operations in 1915 by purchasing an unfinished aluminum smelting complex.1 By 1917, a dam constructed over the Yadkin River adjacent to the Badin Works at a location known as the Narrows powered the aluminum 1 Alcoa-Yadkin History, ALCOA, http://www.alcoa.com/yadkin/en/info_page/history.asp (last visited Jan. -

Chapter 57 – Smelter Wastes and Cleanups
Chapter 57 Smelter wastes and cleanups The Columbia Falls Aluminum Co. plant site, like other heavy industrial sites, was impacted by the typical variety of hazardous chemicals used by maintenance and production personnel or created as a result of process operations. The large number of vehicles necessitated a maintenance garage and fuel tanks, some located underground, which over the years generated daily waste or spills that contained solvents, lubricants, diesel fuel and gasoline. The vast array of mechanical processing equipment – from crushers, shakers and feed belts to pollution-control equipment, casting equipment and overhead cranes – likewise required maintenance crews and repair facilities that generated similar waste over the years. The 600 reduction pots required periodic rebuilds over their lifespan. Equipment maintenance and process operations also were responsible for producing heavy metals. The large transformers and other electrical equipment were a source for polychlorinated biphenyls (PCBs). Asbestos was used to insulate exhaust fues and steam pipes, as well as a binder in roofng material and fooring tile. 1 In addition to the typical hazardous chemicals found at many industrial sites were the chemicals associated with the aluminum smelting process – including coal, coke and coal tar pitch used to make carbon paste briquettes and a source of emissions from open-topped Soderberg anodes; fuoride compounds used to make bath and emitted by reduction pots in pot gases or fugitive emissions in potrooms and by crushing and handling frozen bath; dross produced by casting furnaces and operations; and spent potliner created in cathode pot bottoms. Spent potliner at aluminum smelters consisted of refractory brick, cathode electrodes and carbon paste which contained various hazardous compounds created after years of pot use, including ammonia and cyanide. -
Badin Lake Sediment Remedial Action Plan
Alcoa Corrective Action Badin, North Carolina Corrective Action Activities Alcoa began operations at the Badin site in 1915 as a primary aluminum smelter. Principal products manufactured at the plant include carbon cathodes and anodes, continuous cast sheets and specialty metals. Alcoa reduced aluminum smelting operations at the Badin facility in 2002 and ceased operation in 2007. The Alcoa plant site is approximately 123 acres in size. The site contains industrial buildings and structures, parking lots, and areas covered with vegetation. Alcoa owns land that extends to Badin Lake, however the industrial plant property extends only to Highway 740 and does not abut the lake. Alcoa was issued a Hazardous Waste Management Permit to store spent potlining on March 30, 1992 and the permit was renewed on March 24, 2006. The Hazardous Waste Management Permit required Alcoa to identify and investigate solid waste management units for potential adverse impact to the environmental media at the Badin facility. A solid waste management unit is any discernible waste management unit at a RCRA facility which has been used for the treatment, storage, or disposal of solid waste at any time, irrespective of whether the unit is or ever was intended for management of solid waste. The contamination at the site is predominantly inorganic compounds (cyanide and fluoride) from the production of aluminum. Low concentrations of organic constituents (mainly polycyclic aromatic hydrocarbons, PCB aroclors, and trichloroethene) are found in localized areas of the plant site associated with a limited number of solid waste management units. Interim measures were conducted from 1996 to 2012 on eight solid waste management units at the site to minimize the threat of further environmental releases from those units. -

An Evaluation of Water Quality Parameters and Flow Dynamics In
An Evaluation of Water Quality Parameters and Flow Dynamics in High Rock Lake, North Carolina to Assist in the Development of Nutrient Criteria for Lakes and Reservoirs in the State by Morgan Rudd Dr. Michael O’Driscoll, Advisor Dr. Grant Murray, Advisor April 26th, 2018 Master of Environmental Management Degree Candidate | May 2018 Masters project submitted in partial fulfillment of the requirements for the Master of Environmental Management degree in the Nicholas School of the Environment of Duke University EXECUTIVE SUMMARY North Carolina reservoirs have a history of eutrophication problems, and studies addressing NC lake water quality were conducted as early as the 1960s. Most of North Carolina’s lakes are manmade reservoirs, and reservoir waters may respond differently to nutrient inputs based on differences in watershed area, residence time, depth, and other variables. A better understanding of riverine discharge and water quality parameter dynamics in North Carolina reservoirs will help guide nutrient development for the state. Due to impairments associated with designated uses for water supply, recreation, and aquatic life, High Rock Lake (HRL) has been listed on North Carolina’s 303d list of impaired waters since 2004. The lake and its tributaries are impaired due to elevated turbidity, chlorophyll-a, and pH. High Rock Dam, located in Rowan and Davidson Counties in North Carolina, was constructed on the Yadkin River in 1927. HRL is primarily fed by the Yadkin River and several smaller tributaries, draining a total area of 3974 square miles. North Carolina currently has surface water standards for chlorophyll-a (40 µg/L), turbidity (25 NTU- lakes), and pH (<6 or >9), but not for nutrients. -

Box 576 Badin, NC 28009 Subject: Comments on LIHI recertification, Tapoco Hydroelectric Project (FERC No. P-2169) Dear Marshall: The purpose of this letter is to provide information for Alcoa Power Generating Inc (APGI) to use in its application for recertification by the Low Impact Hydropower Institute (LIHI). On July 25, 2005, the LIHI certified Alcoa's Tapoco Hydroelectric Project as Low Impact. That certificate is set to expire July 25, 2013. The Tapoco project consists of four powerhouses and four dams in eastern Tennessee and western North Carolina totaling 350 megawatts (MW) of electric generation capacity, which power Alcoa Tennessee Operations near Knoxville. The project is located on the Little Tennessee and Cheoah Rivers and is owned and operated by Alcoa Power Generating Inc. The Tapoco Project includes four developments - Santeetlah Development, Cheoah Development, Calderwood Development, and Chilhowee Development. The Tapoco Project extends along the Little Tennessee River from about River Mile 33 to just above RM 60, downstream of the Tennessee Valley Authority Fontana Dam. Chilhowee, Calderwood and Cheoah developments and Santeetlah Powerhouse are located on the Little Tennessee River. Santeetlah Dam and Reservoir are located on the Cheoah River, a tributary to the Little Tennessee River. The Project Boundary encompasses much of the Cheoah River corridor downstream of the Santeetlah Dam. Background USFWS Participation. The Fish and Wildlife Service was an active participant in the collaborative relicensing process.
