(DEP) owns and operated the W. H. Weatherspoon Steam Electric Plant (Weatherspoon Plant) located on the north side of the Lumber River in Lumberton, Robeson County, North Carolina. As required by the Weatherspoon Plant's National Pollutant Discharge Elimination System(NPDES)Permit No.NC0005363,DEP will annually monitor arsenic,selenium,and mercury in fish tissue in the Lumber River. This study plan is submitted for approval to fulfill the monitoring requirements under Part I,Section A.(14)Fish Tissue Monitoring Near Ash Pond Discharge(Outfall 001 and Emergency Outfall 003). 2.0 Site Descriptions and Sampling Locations Fish muscle tissues will be sampled from the Lumber River at two areas near the Weatherspoon Plant(Figure 1). A location upstream(UP) of discharge point will serve as a reference location to monitor background elements concentration in fish muscle tissue and a location in the immediate vicinity of the discharge point (DI) will serve to monitor near-field uptake and assimilation of elements in fish muscle tissue. The upstream sampling location (UP) will start approximately 3 river kilometers (rkm) above the discharge point and extend approximately 1.5 river kilometers downstream. The discharge sampling location will start approximately 0.5 rkm above the discharge point and extend approximately 1.0 rkm downstream. 3.0 Target Species The proposed target species are based on prior sampling experience, species availability, importance as fish food, predatory nature of certain species, and general trophic level. Proposed target species will be Black Bass (Micropterus spp.) and Sunfish (Lepomis spp.). Duke Energy will attempt to collect six individuals of each group. Specimens retained for analysis will be larger individuals of older age and sufficient for human consumption. As recommended by the U.S. Environmental Protection Agency(USEPA), an attempt will be made to ensure that the size of the smallest individual sampled will not be less than 75% of the total length of the largest fish within each species group (USEPA 2000). An attempt will be made to conform to this number and size criteria;however,the number and size of each species will depend upon the availability of species at a particular sampling area. 1 4.0 Field Sampling Methods The following active and passive sampling methods may be employed to efficiently collect target species: boat electrofisher (pulsed DC current), hoop nets, gill nets, and trotlines. Standard sampling methods will be used for each gear type as outlined in the American Fisheries Techniques Manual (Zale, Parrish, and Sutton 2012). Nets and trotlines will be checked at approximately 24- hour interval during the sampling period. Fish retained for trace elements analysis will be identified to species, measured for total length to the nearest millimeter, weighed to the nearest gram, immediately placed in a labeled (date, location,etc.)bag and stored on ice until they can be frozen. Only fresh fish that show no signs of deterioration will be retained for analysis. Fish that have visible, open wounds that can allow contamination will not be retained. Other supporting environmental data will be collected during each trip. Water quality, consisting of temperature, dissolved oxygen, and specific conductance will be monitored at the surface of each sampling area during the sampling period. Other environmental conditions may be noted during each sampling period include river flow conditions (discharge based on the nearest U.S. Geological Survey gauging station), weather conditions, and other conditions that may assist in data interpretation. 5.0 Laboratory Processing and Metals Analysis All fish will be processed in the laboratory for metals analysis according to DEP procedure NR- 00107 Revision 4 Trace Elements Monitoring Laboratory Procedure (approved SOP on file with the North Carolina Department of Environmental Quality). Sample custody and tracking of samples will be performed using chain-of-custody forms during transport to or from the laboratory. Quality of vendor laboratory data, if applicable, will be ensured through the use of National Institute of Standards and Technology tissue standards. The remaining processed sample will be archived for two years if re-analysis is needed. 6.0 Reporting Arsenic, mercury, and selenium concentrations (converted to µg/g fresh weight) determined from individual fish tissue analyses will be reported. A report with the sampling methods,data analysis, 2 and conclusions will be prepared and submitted with the subsequent NPDES permit renewal application as required by NPDES Permit No. NC0005363. 7.0 References USEPA. 2000.
