Jones Street Raleigh, NC 27603 ming.chao@ncdenr.gov RE: City of High Point - Kersey Valley MSW Landfill (Permit No. 41-04) Leachate Management System Modifications Response to Review Comments Dear Mr. Chao: On behalf of the City of High Point, Smith Gardner, Inc. (S+G) would like to respond to the comments in your email dated and received by S+G via email on December 14th, 2018 (see attached). These comments are repeated below in italics followed by our response in bold. Leachate Pond Closure 1. Please provide a detailed soil sampling plan including sampling depth at each location, the sampling scheme – composite or discrete samples, sampling tools and decontamination procedures, etc., and the proposed nine (9) soil sample locations should be shown on a drawing. A sampling and analysis plan, including a figure, has been prepared and is provided as an enclosure. 2. After closing the leachate pond, will the pond be backfilled with clean fill and re- graded/reseeded to match surrounding grades for facilitating surface drainage? Or the pond will be converted into a sedimentation basin. Please provide the post-closure land use at this location. Upon closure the pond will be backfilled with clean soils, graded to drain to a new culvert (which will drain to an existing sediment basin), and the area will be revegetated. The area may be utilized in the future as a stockpile area for clean soils or materials. 3. (Drawing No. S2) Regarding the sediment/sludge removal from the leachate pond prior to removing the pond liner, please add the liquid restriction requirement for the sediment / sludge disposal to the Note 3. Prior to disposal, the sludge/sediment must be examined & documented to ensure it either is free of liquid or passes the test - the SW-846 Test Method 9095B: Paint Filter Liquids Test. Note 4 has been added to address this. A copy of revised Drawing S2 is provided as an enclosure. DocuSign Envelope ID: 96D9208A-5169-49D5-B8C1-063960EF2171 Mr. Ming-Tai Chao, P.E. January 17, 2019 Page 2 of 3 4. 1,4-dioxane exceedance is detected in the monitoring well, MW-9 in 2018 groundwater sampling report (FID 1261073). Since the well is in the close vicinity of the leachate pond which is receiving leachate from Phase 3, a potential source of the chemical of concern (COC), to confirm if this COC exists, it is recommended to test soil samples underneath the leachate pond for 1,4-dioxane, in addition to the components in the Appendix I. Analysis for 1, 4 dioxane is included in the enclosed sampling and analysis plan. Phase 3 Sump Improvements 5. The proposal states that “the Phase 3 sump is not operating by gravity as intended and the connection to the gravity pipe leading away from the landfill is believed to be clogged.” For the clarity, please mark/note this clogged pipe on the drawing. Phase 3 was designed with a vertical drop into a pipe underneath the landfill leading to the existing leachate manhole. The vertical section is the portion which is believed to be clogged. Enclosed are copies of two drawings from construction of Phase 3 with notation added showing the location of the clog. 6. The approved Closure and Post Closure Plan (DIN 21805) stated that leachate flow rate in closed Area 1 unit is about 100 gallons/acre/day. The new proposed flow rate at Phase 3 sump is 50 gallons/acre/day, which is a half of the originally estimated amount. Is this new proposed flow rate based on any historical leachate record or just an engineer judgement? The assumed 50 gallons/acre/day (gpad) flow rate is believed to be conservative based on the approximate quantity of leachate periodically pumped by the City from the Phase 3 sump. The 100 gpad value assumed in the Closure and Post-Closure Plan, is a typical rule-of-thumb/engineering judgement used by S+G for recently closed areas. Even at the higher flow rate of 100 gpad (approximately 1,300 gallons/day for Phase 3), the capacity of the proposed pump is more than sufficient. 7. The proposed force main must pass hydro-static pressured test. Please add the test specification/criterion to the proposal. Pressure testing of the force main is planned. The project specifications are provided as an enclosure (reference Section 02614, HDPE Pipe). 8. The referenced survey drawing – Kersey Valley Landfill Storm Drainage, Leachate Main& Sanitary Sewer dated October 25, 2016 can’t be located in the SWS file system. Please provide a copy for our record. A copy of the requested drawing prepared by Schneider, Inc. is provided as an enclosure.

The proposal should also address the following health & safety matters, such as OSHA trench safety & confined space entry, and potential methane exposure including fire result from a spark, and interference the existing LFGCCS operation, etc. The contract for the project requires the contractor to comply with all applicable safety and health requirements and to provide a copy of their safety program. The project specifications also note various safety requirements (for example, reference Paragraph M.3 (LFG Hazards) of Section 01010). Additionally, each of the project drawings includes a safety note.

Environmental Engineer NC DEQ Division of Waste Management 217 W. Jones Street Raleigh, NC 27603 ming.chao@ncdenr.gov RE: Leachate Pond Removal Soil Investigation Plan High Point Kersey Valley Landfill High Point, North Carolina Dear Mr. Chao: On behalf of the City of High Point, Smith Gardner, Inc. (S+G) has prepared this Leachate Pond Removal Soil Investigation Plan in response to comments regarding the removal of the leachate storage pond on the south side of Area 1 at the Kersey Valley Landfill Facility. Removal of the pond is scheduled to begin in March 2019. To evaluate potential impact resulting from the presence of the pond, S+G will perform the following scope of work. Sampling Plan Soil Sample Collection and Analysis After removal of the existing HDPE geomembrane liner and any visibly stained soils that may be beneath, S+G personnel will collect eight (8) discreet soil samples from the area shown on the attached Figure 1. Due to the naturally occurring inorganic metals in the soils of North Carolina, S+G will also collect a background sample from a location upgradient of the landfill (not pictured in Figure 1) to compare the results from the pond samples to background soil conditions. Each soil sample will be collected from a depth between one (1) and two (2) feet below (excavated) grade. Soil samples will be analyzed for the Appendix I list of constituents (40 CFR 258 Appendix I) and for 1,4 dioxane by EPA Method 8260 SIM by a North Carolina certified laboratory. Reporting After receipt of the laboratory analytical data, S+G will submit a report to the NCDEQ summarizing sample collection techniques and laboratory analytical data results. Analytical data will be compared to site background conditions (Upgradient soil analysis) and relevant standards (NC Soil Preliminary Soil Remediation Goals). This report will also include a map of sampling locations, conclusions, and recommendations.

If the submittals contain any departures from the Contract Documents, specific mention thereof shall be made in the Contractor's letter of transmittal. Otherwise, the review of such submittals shall not constitute approval of the departure. C. Procedure for Review 1. Submittals will be reviewed and annotated by the Engineer in one of the following ways: “Furnish as Submitted” - no exceptions are taken. “Furnish as Noted” - minor corrections are noted and shall be made. “Revise and Resubmit” - major corrections are noted and a resubmittal is required. “Rejected” - Based on the information submitted, the submission is not in conformance with the Contract Documents. The deviations from the Contract Documents are too numerous to list and a completely revised submission of the proposed equipment or a submission of other equipment is required. 2. If a submittal is satisfactory to the Engineer, the Engineer will annotate the submittal “Furnish as Submitted” or “Furnish as Noted” and transmit electronically to the Contractor. For hard copy submittals, the Engineer will transmit two (2) copies to the Contractor. 3. If a resubmittal is required, the Engineer will annotate the submittal “Revise and Resubmit” or “Rejected” and transmit electronically to the Contractor for appropriate action. For hard copy submittals, the Engineer will transmit four (4) copies to the Contractor for appropriate action. 4. The Contractor shall revise and resubmit submittals as required by the Engineer until submittals are acceptable to the Engineer. 5. No materials or equipment shall be ordered, fabricated, shipped, or any work performed until the Engineer returns to the Contractor the submittals, herein required, annotated either “Furnish as Submitted” or “Furnish as Noted”. 6. The Engineer's review of the Contractor's submittals shall in no way relieve the Contractor of any of their responsibilities under the Contract. An acceptance of a submittal shall be interpreted to mean that the Engineer has no specific objections to the submitted material, subject to conformance with the Contract Drawings and Specifications. 7. The Engineer's review will be confined to general arrangement and compliance with the Contract Drawings and Specifications only, and will not be for the purpose of checking dimensions, weights, clearances, fittings, tolerances, interferences, coordination of trades, etc. DocuSign Envelope ID: CA50BB9A-22B5-4870-92C9-D0CACA192D80DocuSign Envelope ID: E4043B89-ADEF-4F01-8265-986C8B70AD64 Kersey Valley Landfill –Leachate Management Modifications General Specifications October 2018 Submittals Page 01300-3 8.
