Suncrest Chip Mill Haywood County ________________________________________________________________________ Dear Mr. Laverty, Powell Industries, Inc. submitted a closure plan to NC Department of Environmental, Division of Water Resources (DWR) on August 14, 2018. The plan was approved on November 5, 2018. The plan described sampling of water and wastewater residuals to be conducted as part of the wastewater pond closure. This report summarizes results of initial stormwater samples collected at the wastewater pond outfalls prior to rerouting of stormwater from the wastewater pond, a wastewater grab sample, and wastewater residuals samples collected from the dewatered wastewater pond (WWP). A temporary stormwater bypass trench was excavated to reroute stormwater from the WWP to the Lower pond. The trench is excavated west of the WWP extending from a concrete junction box located immediately southwest of the WWP, around the west side of the WWP, and discharging into the Lower Pond. A partial breach was excavated by Powell Industries in the dam of the Lower Pond to manage flooding associated with heavy rains last year and reduce the potential of an uncontrolled breach of the Lower Pond dam. The area adjacent to the bypass trench was planted with grass and covered with erosion control matting to stabilize the banks on either side. The partial breach in the Lower Pond dam was stabilized by placing hay bales at intervals in the discharge channel within and below the dam. When the WWP closure is complete, culvert pipe may be placed in the trench and backfilled, or the trench will be maintained with the sidewalls being laid back to a 2:1 slope and stabilized with vegetation and erosion control matting. Figure 1 shows the WWP and the Lower Pond as well as sample locations and temporary stormwater conveyances. June 18, 2019 Page 2 MSGS SAMPLING AND ANALYSIS Over the past six months, stormwater, impounded wastewater and wastewater residuals have been sampled and analyzed to monitor stormwater discharges, and determine how water and sediment will be managed during closure of the pond. Stormwater was sampled October 11, 2018 and a second time in February 2019. The October 11, 2019 sample was analyzed for 13 metals including arsenic, cadmium, calcium, chromium, copper, lead, magnesium, mercury, molybdenum, nickel, selenium, sodium, zinc; volatile organic compounds (VOCs); semi-volatile organic compounds (SVOCs); turbidity; total suspended solids (TSS); BOD; pH; ammonia; total Kjeldahl nitrogen (TKN); nitrogen, NN2/NO3; nitrate; nitrite; total phosphorus; and total phenolics. The February 2019 sample was analyzed for COD and TSS as required in the General Stormwater Discharge Permit for the site. The October 2018 stormwater samples were collected at the site drainage outfall into the WWP. After results were received and the stormwater bypass trench was excavated, the outfalls were disconnected at a concrete junction box and the pipes into the WWP blocked to prevent any additional stormwater from entering into the WWP and preventing backflow of wastewater into the stormwater bypass trench. The February 2019 sample was collected at the discharge from the lower pond. The turbidity concentration detected at 19.9 NTU in stormwater sample SW-02 exceeded the NC 15A NCAC 02B surface water quality standards for classified Trout waters (<10 NTU). Total suspended solids (TSS) detected in sample SW-02 at 99.2 exceeded the Stormwater General Permit benchmark value of 50 mg/L. No VOCs or SVOCs were detected in either sample. Results are summarized in Table 1. Analytical reports are attached. A wastewater sample was collected from the WWP on February 14, 2019 and analyzed for the same parameters as the stormwater samples described above. The results are summarized in Table 2. Wastewater was pumped from the pond into tankers and transported to the local POTW for disposal. After the WWP was dewatered, two wastewater residual samples were composited from eight locations (four per composite) in the WWP. Eight grab samples were collected for analysis of VOCs. From each set of four grab samples, composite samples were prepared for analysis of inorganic and SVOC parameters. Grab samples of each aliquot were collected for analysis of VOC constituents before combining for the two composite samples. The composite samples were analyzed for SVOCs; 13 metals including arsenic, cadmium, calcium, chromium, copper, lead, magnesium, mercury molybdenum, nickel, selenium, sodium, zinc; ammonia nitrogen; total Kjeldahl nitrogen (TKN); nitrogen, NN2/NO3, June 18, 2019 Page 3 MSGS nitrate; nitrite; total phosphorus; and total phenolics. The eight grab samples of residuals were analyzed for VOCs. Sample results were compared to the NCDEQ Protection of Groundwater Preliminary Soil Remediation Goals (PSRGs). Acetone was the only VOC detected in the wastewater residual grab samples. The concentrations range from 434 ug/Kg to 586 ug/Kg. The detected concentrations are below the Protection of Groundwater Standard PSRG. Table 3 summarizes the composite wastewater residual analytical results. A total of 10 metals were detected in wastewater residual composite samples. All were below the Protection of Groundwater PSRGs. Chromium was analyzed as total chromium (unspeciated). The concentrations detected were 59.9 and 66.5 mg/Kg. A TCLP analysis was conducted to ensure that the leachable concentration s were below the TCLP standard for total chromium. The TCLP result for chromium was 0.77 mg/L for sample C-1 and non-detect for C-2. Since the analytical results for all regulated inorganic analytes are below leachable thresholds and VOCs were not detected except for acetone, which was well below its Protection of Groundwater PSRG, soils beneath the residual layer were not sampled. WWP Closure Based on the analytical results, Powell Industries, Inc. proposes to close the WWP residuals in place. The stormwater that has accumulated in the pond since sampling was completed will be pumped into tankers and transported to the local Publically Owned Treatment Works (POTW) for disposal. The residuals remaining in the pond will be covered with clean backfill. The surface of the backfill will be graded to shed stormwater and planted with grass to control erosion. Stormwater Management Based on stormwater sample results, stormwater management measures will be designed. The preferred option is to the abandon upstream WWP rather than retrofit it as a stormwater detention pond. Instead, in the preferred plan, stormwater would be allowed to flow through lower pond basin, after the downstream dam has been fully breached. Treatment function can be enhanced in the lower pond area by constructing a stable sinuous treatment wetland flow path. Plans for treating stormwater are in process. Stormwater sampling is proposed at two sites as show on Figure 2 and depicted in Photographs 1 and 2. Stormwater constituents required for sampling and testing are summarized in the Closure Plan. The two sample sites selected are as follows: Site 1: Outflow from downstream property limit downstream of lower pond. Site 2: Outflow from piped system, prior to entering June 18, 2019 Page 4 MSGS the temporary diversion channel. Proposed stormwater sampling plan and protocols will be sent to NCDEQ Stormwater Division for review and concurrence prior to commencing sampling. The current temporary bypass channel includes steep side slopes that are subject to erosion as shown in Photographs 3 and 4. Options for stabilizing a permanent bypass system include: a. Installing a pipe along the alignment of the existing temporary bypass channel; b. regrading the channel with 2:1 (H:V) or gentler side slopes, revegetating the channel, and installing erosion control matting as needed. The dam for the downstream pond was recently partially breached shown in Photograph 5. Full breaching of the dam will allow the pond to drain and no longer impound stormwater. A plan for breaching the downstream dam of the lower pond will be developed to minimize the risk of releasing sediment from the downstream pond into Jonathan Creek. This plan will be submitted for approval by NCDEQ. Once the full stormwater treatment system has been implemented, a maintenance plan will be developed and followed for regular maintenance of the downstream treatment wetland. Powell Industries, Inc. requests approval to close the wastewater residuals in-place in the WWP and cover with clean fill. The analytical results do not indicate constituent concentrations above regulatory standards or leachable concentrations of any constituents detected in residual samples. The closure plan is also modified by the proposed stormwater management plan summarized in this report. Approval of the stormwater management concept is requested.

NATIONWIDE.GLOSSARY OF TERMS Guide to Reading and Understanding Your Laboratory Report The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative. Abbreviations and Definitions (dry)Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils]. MDL Method Detection Limit. MDL (dry)Method Detection Limit. RDL Reported Detection Limit. RDL (dry)Reported Detection Limit. Rec.Recovery. RPD Relative Percent Difference. SDG Sample Delivery Group. U Not detected at the Reporting Limit (or MDL where applicable). Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported. Dilution If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor. Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges. Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG. Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable. Result The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte. Uncertainty (Radiochemistry)Confidence level of 2 sigma. Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. Quality Control Summary (Qc) This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material. Sample Chain of Custody (Sc) This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis. Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported. Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis. Qualifier Description B The same analyte is found in the associated blank. J The identification of the analyte is acceptable; the reported value is an estimate. J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low. P1 RPD value not applicable for sample concentrations less than 5 times the reporting limit. 1 Cp 2 Tc 3 Ss 4 Cn 5 Sr 6 Qc 7 Gl 8 Al 9 Sc ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Pace Analytical - Asheville, NC 92425518 L1091257 04/29/19 12:28 9 of 12 ACCOUNT:PROJECT:SDG:DATE/TIME:PAGE: Pace Analytical - Asheville, NC 92425518 L1091257 04/29/19 12:33 9 of 12 Page 64 of 67 ONE LAB.

ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and bias for a specific analyte in a specific matrix. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. Acid preservation may not be appropriate for 2 Chloroethylvinyl ether. A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA Method 8260. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for each analyte is a combined concentration. Pace Analytical is TNI accredited.
