Box 576 Badin, NC 28009 Tel: 1 704 422 5865 January 27, 2022 ATTN: Derek Denard Division of Water Resources WQ Permitting Section – NPDES 1617 Mail Service Center Raleigh, NC 27699-1617 Re: Response to Information Request Badin Business Park LLC NPDES No. NC0004308 Stanly County Mr. Denard: Please find attached Badin Business Park LLC’s responses to the Division of Water Resources request for information regarding the recent soil removal project, dated December 20, 2021. As you will see in the detailed responses below, this effort was part of our ongoing efforts to investigate and address potential sources of constituents on the site, particularly with regard to Outfall 005. For ease of discussion and mutual understanding, each request raised by your office is presented below in bold and italics and is followed by Badin Business Park’s (BBP) response. We hope you find the following sufficient to address your concerns. Please contact me should you have additional questions or concerns regarding this project. 1. Provide a map depicting the footprint of the excavated area and reasons and supporting data for the removal of the soils. Response: The excavation of soils from an area near the former Bath Mill (Building 204H) was conducted during the week of October 11, 2021 as a positive step towards BBP’s commitment to investigate and address potential sources of constituents quantified in aqueous samples collected at Outfall 005. A depiction of the excavated area is provided on Figures 1 & 2 as Attachment 1. The basis for pursing the project is as follows. In March 2020, an electromagnetic (EM) geophysical evaluation was performed to assess for the presence of previously unknown sources and/or pathways for constituents to enter the Outfall 005 storm sewer system. The geophysical survey was conducted on an approximate eleven-acre area west of the former potrooms and an approximate seven-acre area north of the former potrooms. The EM method was selected due to its ability to detect variations in shallow subsurface soil conductivity, variations in shallow groundwater conductivity, and metallic materials. Results from the EM evaluation were suggestive of potential buried structures, materials, and conductive porewater and/or groundwater. One EM response corresponded to the location of the Mr. Derek Denard January 29, 2022 Page 2 former Bath Mill where recovered bath material, a fluoride-bearing mixture from the aluminum reduction pots, was crushed and repurposed. This location is also near the Outfall 005 storm sewer system. In June 2020, four test pits (TP-205 through TP-208, See Attachment 2 for location) were installed at the former Bath Mill and samples of soil and water were collected for analysis. The results of the soil and water analysis are presented in Tables 1 and 2 respectively. Additionally, the laboratory reports are included as Attachment 3. These sample results and the corresponding proximity to the Outfall 005 storm sewer network confirmed that the former Bath Mill area had a potential to contribute to constituents quantified in aqueous samples collected at Outfall 005.

This map, or information in support of the map, must indicate the area of onsite excavation, include the dimensions of the excavated area, the total volume of soils excavated, and any pre- activity topographic survey of the excavated area that may exist, as well as a topographic survey of the post excavation area. Response: The approximate boundaries of the excavation area are shown on Figures 1 and 2. The dimensions of the excavated area were approximately 80 feet (north/south) by 50 feet (east/west). The pre-excavation topography is shown on Figure 1; the excavation area and adjacent areas are generally flat. Soils to a depth of eight feet below grade (~1,200 In-Situ Cubic Yards) were excavated and loaded to trucks. A total of 102 truckloads containing approximately 1,893 tons of solid materials were sent offsite for disposal. An additional three to four feet of soils below the base of the excavation were excavated to be mixed with quick lime at an approximate 5-10% dosing ratio by mass. The remaining excavation was backfilled to match surrounding grade with native soils supplied from a local property (61608 Hwy 740 in Badin NC). 3. Explain how much surface area was disturbed (including access roads), detail what stabilization measures/erosion control measures were used and if there were any erosion/turbidity issues with the area of disturbance. Response: See previous response for description of excavation area. Truck traffic was limited to existing paved access roads. No erosion/turbidity issues were identified as construction occurred during a brief period of time with no precipitation. Further, the excavation was performed such that potential runoff would be directed inward into the excavation. 4. Detail how the excavated area was stabilized, if the area was back filled or capped, and where this back fill material came from. Also, explain how the work area was ultimately managed such that soils, turbidity, solids or other waste did not erode or otherwise course from the area of disturbance to surface waters. Response: See previous responses. Mr. Derek Denard January 29, 2022 Page 4 5. Detail how this work and the ultimate stabilization of the area was monitored during this effort. Response: Monitoring of the construction activity was conducted periodically by both Site personnel and a consultant. 6. A DWR NPDES file review did not reveal notification of this soil removal activity for the project starting on October 12th. Please provide any prior notifications (e.g. including plans for this material removal, information on truck traffic, ultimate disposal, or of this work occurring on October 12, 2021). Response: Notification of the investigation activity leading to the decision to remove this material was first reviewed with DWR personnel during a meeting (conducted remotely) on February 18, 2021 to review the Outfall 005 compliance status. The plan to remove the material was later discussed with DWR personnel during a follow up meeting (conducted remotely) on June 15, 2021. The slides shared during the meetings along with the respective meeting invitations are attached for reference as Attachment 2. During both meetings, there was a general recognition that the removal could be a self- implemented activity given the facts of the matter. A courtesy call was made to the Division of Waste Management (DWM) the week prior to keep the DWM apprised of on-site activity. 7. Include a photographic record of the excavation area prior to excavation (if one exists) and a photographic record of the current site conditions. Response: Three photos are provided. One prior to excavation, one during excavation, and one post excavation. Pre-Excavation Photo (Taken June 2020) Mr. Derek Denard January 29, 2022 Page 5 Representative Open Excavation Photo (Taken Oct 14, 2021) Post Excavation Photo (Taken Jan 10, 2022) 8. Provide all sampling results and laboratory analytical documentation of the excavated soils. Response: See previous response for a summary table of investigative results and reference to the laboratory reports. 9. Provide a complete record of the NPDES monitoring that occurred during and after the excavation activities and identify any changes that may have occurred because of the soil disturbance. Mr. Derek Denard January 29, 2022 Page 6 Response: No changes were observed correlated to this activity. NPDES monitoring prior, during, and after the excavation activity has been documented in routine discharge monitoring reports (DMRs). 10. Provide documentation that the soil excavation did not impact an existing RCRA solid waste management unit or area of concern. Response: The excavation area is not associated with an existing RCRA solid Waste Management Unit or Area of Concern. See the following figure which shows the location of the excavation area compared to the location of the identified SWMUs (shown in blue). Mr. Derek Denard January 29, 2022 Page 7 11. Finally, please provide any data/information you provided and explain in your written response the information you provided to the landfill, (Republic Services' Uwharrie Landfill in Montgomery County, NC) as to the sample results and sources of this material for use as cover material. Response: A verbal inquiry for disposal of the soil and crushed concrete was first made to the landfill representative by telephone in early March 2021 followed by the submittal of analytical results by email accompanied with the following text, “Attached is the analytical for the 1900 tons of soil and crushed concrete. Can you provide a profile and disposal cost per ton for this material. They will deliver this material over the course of one week approximately 80 -85 loads.” The analytical results, included as Attachment 4, are of a representative sample composited from several grab samples collected from the soils returned to the test pit locations at the bath mill area as previously described. The landfill provided a Waste Profile by email for review and signature (see Attachment 5). Sincerely, Robyn L.

In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In the event of interference or analytes present at high concentrations, samples may be diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. EXCEPTIONDuring the Fluoride distillation for method 4500 of ABP-TP-207(2.0), a violent reaction took place that caused the distillation apparatus to explode. The laboratory determined they would be unable to distill the remaining samples, due to EHS concerns. As a result, he following samples were not analyzed for Fluoride using Fluoride distillation method 4500: ABP-TP-206 (4.0) (680-185778-8), ABP-TP-207 (2.0) (680-185778-9), ABP-TP-207 (9.5) (680-185778-10), ABP-TP-208 (2.0) (680-185778-11) and ABP-TP-208 (9.5) (680-185778-12).

In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In the event of interference or analytes present at high concentrations, samples may be diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. REVISION Sample ID prefix was revised to ABP RECEIPT The samples were received on 07/01/2020; the samples arrived in good condition, properly preserved and on ice. The temperature of the coolers at receipt was 2.5 C. ANIONS BY ION CHROMATOGRAPHY (28 DAY) Samples ABP-TP-202W (680-185779-1), ABP-TP-204W (680-185779-2) and ABP-TP-205W (680-185779-3) were analyzed for Anions by Ion Chromatography (28 Day) in accordance with EPA Method 300.0. The samples were analyzed on 07/04/2020 and 07/10/2020. Sample ABP-TP-205W (680-185779-3)[5X] required dilution prior to analysis. The reporting limits have been adjusted accordingly. No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. CYANIDE Samples ABP-TP-202W (680-185779-1), ABP-TP-204W (680-185779-2) and ABP-TP-205W (680-185779-3) were analyzed for cyanide in accordance with D7511-12. The samples were analyzed on 07/13/2020. The following samples were found to contain residual chlorine: ABP-TP-202W (680-185779-1), ABP-TP-205W (680-185779-3) and ABP-TP-204W (680-185779-2). The chlorine was treated and removed prior to preparation/analysis.
