Supplement to Drinking Water Well And Receptor Survey November 2014 Mayo Steam Electric Plant - Roxboro, NC SynTerra 1.0 INTRODUCTION The attached figure and table have been prepared to provide an update to the Drinking Water Well and Receptor Survey Report (SynTerra, September 2014) for the Mayo Steam Electric Plant (Mayo Plant). The report and this update have been prepared to meet the requirements of the Coal Ash Management Act 2014 - North Carolina Senate Bill 729 (August 2014) and the Notice of Regulatory Requirements (NORR) (August 13, 2014). Additional water well information has been collected by means of a written survey questionnaire mailed to the owners of properties within 0.5 miles of the Mayo Plant ash basin compliance boundary, which is defined in accordance with 15A NCAC 02L .0107(a) as being established at either 500 feet from the waste boundary or at the property boundary, whichever is closer to the source. The purpose of the questionnaire was to determine if additional wells are present in the area that were not previously observed or have not been previously reported. The questionnaire was also developed to collect additional information regarding potential well locations, well use, well depth and construction, date of completion, etc. for the water wells in the survey area. Information reported from the questionnaire responses, received as of October 31, 2014, has been compiled and is discussed below. Due to the private and sensitive nature of the of the questionnaire responses, the well information has been summarized herein. The completed survey questionnaires are available for future reference. A potential area of interest with respect to the ash basin groundwater flow was delineated and presented in the Survey. Based on the available information, this area is considered to be potentially downgradient from the ash basin.

The GIS data included parcel number, property address, property owner name, and property owner address. A listing of these properties was included as Table 2 of the Drinking Water Well and Receptor Survey Report (SynTerra, September 2014). This information was used to send letters with the questionnaires to each property owner within 0.5 mile of the compliance boundary during the week of October 6, 2014. The questionnaires were sent via Certified Mail with Return Receipt to confirm delivery. The recipients were requested to respond by October 20, 2014. The Certified Mail Return Receipts have been logged as received. Letters returned as undeliverable have also been logged. Questionnaire responses received after October 31, 2014 will be incorporated into the Groundwater Assessment Report required by Senate Bill 729 (Section 130A- 309.209(a)(4)).

Figure 1 attached has been modified to include new and confirmed well locations. The questionnaires were designed to collect information regarding whether a water well or spring is present on the property, its use, and whether the property is serviced by a municipal water supply. If a well is present, the property owner was also asked to provide information regarding the well location and construction information. Summary of Questionnaire Responses as of October 31, 2014 No. of No. of Previously Previously Identified No. of New Identified Wells Wells or No. of No. of Wells Confirmed Springs No. of Return No. of Questionnaires Confirmed by NOT present Identified by Questionnaires Receipts Questionnaires Returned as Property by Property Property Sent Received Received Undeliverable Owner Owner Owner 36 32 19 0 5 0 5 (89%) (53%) (0%) Based upon the previous survey and the questionnaire information, approximately 22 wells may be located within the survey area (reported wells, observed wells and possible wells). The designation for the wells previously assumed to be present (referred to as possible wells, not previously observed or reported) that have been confirmed based upon the survey questionnaire results have been changed from' PRW- _' to 'DW-_' on the table and the figure. The newly reported wells, not previously observed or suspected, are also sequentially identified as 'DW-_'. The survey information indicates 17 reported or observed wells, 'DW-_' and five remain as possible 'PRW-' in the survey area.
