3 I. Overview This nnual Monitoring Report (Report) has been prepared to report the status of activities for the preceding year for the Bottom sh at Cardinal Operating Company s, Cardinal Power Plant. The Cardinal Plant is a three-unit coal-fired generating station with Unit 1 owned by EP Generation Resources, Inc., a wholly-owned subsidiary of merican Electric Power Company (EP), and Units 2 and 3 owned by Buckeye Power, Inc. (Buckeye). The Cardinal Operating Company collectively manages and operates the Cardinal Plant. The USEP s CCR rules require that the nnual Monitoring Report be posted to the operating record for the preceding year no later than January 31, 218. In general, the following activities were completed: Monitoring wells were installed and developed to establish a certified groundwater monitoring system around each CCR unit, in accordance with the requirements of 4 CFR pursuant EP s Monitoring Network Evaluation (216); samples were collected and analyzed for ppendix III and ppendix IV constituents, as specified in 4 CFR et seq. and EP s Sampling and nalysis Plan (216); data underwent various validation tests, including tests for completeness, valid values, transcription errors, and consistent units; Background groundwater values for each ppendix III and ppendix IV constituent were collected; Detection Monitoring sampling was initiated; statistical process in accordance with 4 CFR to evaluate groundwater data was prepared, certified, and posted to EP s CCR website in pril 217 [EP s Statistical nalysis Plan (EP 217)]. The statistical process was guided by USEP s Statistical nalysis of Monitoring Data at RCR Facilities, Unified Guidance ( Unified Guidance, USEP, 29). Data evaluation is underway. The major components of this annual report, to the extent applicable at this time, are presented in sections that follow: map, aerial photograph or a drawing showing the CCR management unit(s), all groundwater monitoring wells and monitoring well identification numbers.; Identification of any monitoring wells that were installed or decommissioned during the preceding year, along with a statement as to why that happened; ll of the monitoring data collected, including the rate and direction of groundwater flow, plus a summary showing the number of samples collected per monitoring well, the 1

4 dates the samples were collected and whether the sample was collected as part of detection monitoring or assessment monitoring programs (ttached as ppendix I); summary of any transition between monitoring programs or an alternate monitoring frequency, for example the date and circumstances for transitioning from detection monitoring to assessment monitoring, in addition to identifying the constituents detected at a statistically significant increase over background concentrations (ttached as ppendix II, where applicable); and Other information required to be included in the annual report such as alternate source demonstration or assessment of corrective measures, if applicable. In addition, this report summarizes key actions completed, and where applicable, describes any problems encountered and actions taken to resolve those problems. The report includes a projection of key activities for the upcoming year. II. Monitoring Well Locations and Identification Numbers The figure that follows depicts the PE-certified groundwater monitoring network, the monitoring well locations and their corresponding identification. 2

6 III. Monitoring Wells Installed or Decommissioned There were no monitoring wells installed or decommissioned in 217. The network design, as summarized in the Monitoring Network Design Report (July 216) and as posted at the CCR web site for Cardinal Plant, did not change. That design report, viewable on the EP CCR web site, discusses the facility location, the hydrogeological setting, the hydrostratigraphic units, the uppermost aquifer, downgradient monitoring well locations and the upgradient monitoring well locations. IV. Quality Data and Static Water Elevation Data, With Flow Rate and Direction and Discussion ppendix I contains tables showing the groundwater quality data collected during the establishment of background quality. Static water elevation data from each monitoring event also are shown in ppendix I, along with the groundwater velocity calculations, groundwater flow direction and potentiometric maps developed after each sampling event. V. Discussion bout Transition Between Monitoring Requirements or lternate Monitoring Frequency s of this first annual groundwater report date there has been no transition between detection monitoring and assessment monitoring. Detection monitoring will continue in 218. The sampling frequency of twice per year will be maintained for the ppendix III parameters (boron, calcium, chloride, fluoride, ph, sulfate and total dissolved solids). Regarding defining an alternate monitoring frequency, the groundwater velocity and monitoring well production is high enough at this facility that no modification of the twice-per-year detection monitoring effort is needed. VI. Other Information Required t the appropriate time the geochemical analyses, coupled with the statistical analyses of the groundwater quality data, will determine whether an alternate source or alternate sources are affecting groundwater chemistry. In those cases where an alternative source(s) demonstration is made, those analyses and supporting information will be presented as well. VII. Description of ny Problems Encountered in 217 and ctions Taken No significant problems were encountered. The low flow sampling effort went smoothly and the schedule was met to support this first annual groundwater report preparation. VIII. Projection of Key ctivities for the Upcoming Year Key activities for 218 include: Detection monitoring on a twice per year schedule 4
