Pyramid Environmental Inc. was retained to perform the required stormwater sampling. The location of our site is shown on the maps in Attachment A. A qualitative monitoring report for Outfall A taken at the time of the sampling event is presented in Attachment B. Laboratory results are presented in Table 1, Attachment C,which lists all results since the installation of Weir A. Table 2, in Attachment C, shows the historical laboratory results for Outfall #1 and #2, which preceded Weir A. The completed Semi-Annual Stormwater Discharge Monitoring Report is included as Attachment D. The analysis of the September 17th sampling event from Weir A recorded the COD at 55 mg/L and the TSS at 14.3 mg/L,therefore,the September 17th sampling event concluded all parameters were below the benchmark concentrations per general permit NCG1200000. Additionally,the sampling event reported a Fecal Coliform value of>12,000 col/100mL,which is above the benchmark. It should be noted however,the landfill was relieved of the compliance requirement for this benchmark because the landfill contains a single waste stream, alkaline batteries,which cannot contribute to this benchmark. If you have any questions,please call Julia Bowman,the Environmental Coordinator for Energizer's Asheboro facilities, at 336/672-4546. Sincerely, Steve Hall Plant Manager 'p.

September 30, 2020 Ms. Julia Bowman Energizer Battery Manufacturing, Inc. 419 Art Bryan Boulevard Asheboro,NC 27203 RE: Semi-Annual Stormwater Sampling and Analytical Results—2nd Half 2020 Energizer Battery Landfill at Randolph County Landfill,Asheboro,NC Pyramid Project#2020-191 Energizer PO#7000046465 Dear Ms. Bowman: As requested by Energizer, Pyramid Environmental & Engineering, P.C. has completed the stormwater sampling and analysis for the referenced site. The site is shown on the site location map included in Attachment A. The Energizer Landfill is located within the Randolph County solid waste landfill and includes one outfall (Weir A). An aerial photograph showing the location of the outfall is included in Attachment A. Corrective Action Plan and Re-Grading of Energizer Landfill In November 2011, Energizer completed corrective actions at the landfill to direct all stormwater run-off from the active and inactive landfill cells to a retention pond on the east side of the property. Areas of the property were graded, and soil berms were constructed to direct all stormwater to the retention pond. The purpose of the corrective actions was to improve the quality of the stormwater run-off that leaves the property. As part of the corrective actions, the two previously used outfalls were eliminated, and a new outfall was created (Weir A). The v- notch weir that was previously located at outfall #02 was moved and installed on the down gradient side of the retention pond in the riprap energy dissipation zone. Sample Collection and Laboratory Analysis On September 17, 2020, the stormwater samples were successfully collected at the site by Tim Leatherman of Pyramid during a representative rain event. The qualitative monitoring report was completed for Weir A by Pyramid and is included in Attachment B. The qualitative monitoring report describes the visual appearance of the stormwater run-off at the time of the sampling event.No unusual conditions were observed by Pyramid. The stormwater samples were placed on ice and transported to Research and Analytical Laboratories, Inc. in Kernersville,North Carolina. The samples were analyzed for fecal coliform, total suspended solids (TSS),chemical oxygen demand(COD) and pH. In 2019,the NC Division of Water Quality added pH to the list of required parameters for General Permit NCG120000.

As shown in Table 1,the detected concentrations of TSS and COD at Weir A do not exceed the benchmark values specified in General Permit NCG120000 and laboratory pH reading was within the specified range of 6.0—9.0. The detected concentration of fecal coliform at Weir A (>12,000 colonies/100 milliliter) exceeds the benchmark value of 1,000 colonies/100 milliliter (ml) specified in the general permit. Energizer has received an exemption from the DEQ for monthly sampling of fecal coliform. Regardless of the results, the fecal coliform analysis is only required as part of the normal semi- annual sampling events. For comparison purposes, a table of historical analytical results for the former outfalls (Table 2) is also presented in Attachment.C. A copy of the laboratory report for the September 17, 2020 sampling event is also included in Attachment C. Based on the results of the September 2020 semi-annual stormwater sampling event, monthly sampling and analysis is not required at Weir A at this time. Pyramid also completed the stormwater discharge monitoring report for Weir A as specified in General Permit NCG120000. The completed monitoring report is included as Attachment D. A representative of Energizer is required to sign page two of the monitoring report and send the original and one copy to the address shown on page two. The next semi-annual sampling event will be performed between January 1 and June 30, 2021. The samples will be analyzed for the compounds as specified in the general permit. Please review this information and call me at 336-335-3174 if you have any questions. Sincerely, alb gr4V)25, Brett S.

(See information below.) Yes ❑ No Please verify whether Qualitative Monitoring must be performed during a "representative storm event"or"measureable storm event"(requirements vary,depending on the permit). j Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be performed during a"representative storm event"or during a"measureable storm event." However, some permits do not have this requirement. Please refer to these definitions,if applicable. A"representative storm event"is a storm event that measures greater than 0.1 inches of rainfall and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than 0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no precipitation. A"measurable storm event"is a storm event that results in an actual discharge from the permitted site outfall. The previous measurable storm event must have been at least 72 hours prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter interval is representative for local storm events during the sampling period,and the permittee obtains approval from the local DWQ Regional Office.
