But the Phase 3 permit application including Facility and C&PC Plans mustreflect the latest changes which, as the basis, will be incorporated into the new permitconditions. Attached is the latest Closure and Post-closure Plan (C&PC Plan) dated December2019 and prepared by LaBella, and you can see the inconsistent info existing in the plan. I received a bond rider/FA amount effective 11/05/2019 which must be the same as theamounts in cost estimates in C/PC & PACA. Please let me know if you have any further questions of the requests.

Send all suspicious email as an attachment to report.spam@nc.gov Ming, While we are finalizing the Coble 3A closure submittal, and reviewing your (below) introduction paragraph, we have questions needing clarification regarding “revised permit renewal application and financial assurance mechanism.” Responses to the permit renewal comments was submitted to the Section in November 1, 2019 and the attached response was received on January 2020 stating “two major issues prevent permit being issued.” 1. Property deed information and financial assurance. Coble provided the deed map on January 17, 2020, and it was acceptable to the Section. 2. Financial assurance was said to be pending the Phase 3A partial closure until the work would be completed, and then the FA would be revised. We have revised closure and post closure plans to be submitted with the 3A Closure report response letter submittal. I had talked about the FA revision with Sarah Rice in March 2020 and it was our understanding that the closure & post-closure plans and FA will be finalized after the phase 3A closure was completed. Coble plans to continue the same financial mechanism as in past with revised acreages closed and active operation.

Please respond the comments in writing and submit a final CQAreport for this 5.6-acre partial closure activity and the revised permit renewal applicationfor Phase 1 thru 3 of the C&DLF including and the rule-required financial assurancemechanism before July 24, 2020. If you have any problem to produce the requesteddocuments by the date of July 24, 2020 for a reasonable cause please contact myself for anew submittal date within five (5) working days (by June 30, 2020) after receiving this e-mail message. The existing permit (DIN 25405) for operating Coble’s C&DLF expired onSeptember 02, 2019, and the Solid Waste Section will revoke the permit and enforce thesite closure on September 02, 2020 if the requested documents/applications are notsubmitted in time for approval. This permit decision was originally sent to your attentionvia an e-mail message on January 08, 2020 (FID 1387209). The comments on the 5.6 acre partial closure CQA Report are: 1. (Sections 1 & 2.2.4) The partial closure report (DIN 24357) and the Phase 3 renewalapplication dated December 2019 (FID 1378626) stated that the disposal area of 9.13acres was partially closed, not 9.8 acres. The total acreage of partial closure areas of theC&DLF shall be 14.73 acres (= 9.13+5.6). Please provide the correct closure acreage. 2. (Section 2.2) This Section states that “the surveyor verified the existing intermediatecover thickness to be a minimum of 12 inches prior to Coble commencing theconstruction of low permeability infiltration soil layer.” There are no survey data inAppendix 3 to confirm that the thicknesses of intermediate cover over the 5.6-acreclosure area meet the specified requirement. Please provide survey data. 3. (Section 2.2.1) According to the CQA plan (including Table 1) and TechnicalSpecifications of the approved Phase 3 PTC application dated March 2008 (DIN 4862),the report does not include the following testing results: i. Construction and QA/QC testing results associated with the test pad of the 18-inch-thick infiltration layer [Sections 02218 & 02229 of the approvedTechnical Specifications (DIN 4862)]. ii. Please explain the discrepancy of number of tests described in Section 2.2.1and those shown in Appendices 1 & 2.

The Engineering Plan and Technical Specification Sections 02224 & 02227and Table 1 (DIN 4862) require the final soil cover system pertaining aminimum friction angle of 26.6 degree by ASTM D4767. Please provide thetesting result in the CQA report. 4. (Section 2.2.2) The results of testing, per requirement listed in Table 1(DIN 4862), onthe protective soil layer/erosion layer are not available in the CQA report. Pleaseprovide the test results. 5. (Section 2.2.3) i. The gas well diameter and the depth deviate from the approved ones (DIN17384). Please explain who approves the deviation and why the approval isacceptable by the Solid Waste Section. ii. This Section states that “for the Phase 3A closure, Coble installed six passivegas vents in a C&D landfill, excavated pits thru the cover and infiltrationlayers to place perforated PVC pipes in the top layer of the waste.” Additionally, the photos in Appendix 2 clearly show that areas for installinggas vent were excavated after the final soil cover was completed installed. Thegas vent construction destroys the constructed soil cover; therefore, the soiltesting (including, but not limited to in-pace density & moisture content andhydraulic conductivity) on each lift per layer must be properly conducted todemonstrate the final cover is successfully restored. 6. (Appendix 1, page 9 of 207) i. The maximum dry density for soil sample CL-1 (Lab ID 2020-019-001-001) is 95.6 pcf. Please correct the typo in the summary table including the % of thecompaction effort. ii. According to Table 1 (DIN 4862), the following soil testing at the frequencyof one test per 10,000 CY is required, but the Lab testing results are notavailable in the CQA report. The required tests are: Particle size (ASTM D422 & D1140), soil classification (ASTM D 2487),moisture content (ASTM D2216), PI (ASTM D4318), Standard Proctor(ASTM D698). 7. (Appendix 2, page 137 of 207) The in-place density test results at the Acre 13 (lift 1) &Acre 12 (Lift 3) that are summarized in Field Daily Report dated 11/26/14 failed to meetthe specified compaction effort - 95% maximum dry density. 8. (Appendix 2, page 150-151) i. The in-place density test results at the Acre 13 (lift 3) are failed to meet thespecified compaction effort - 95% maximum dry density. ii. The density results of sample DC-1 showed on the summary table areinconsistent to those in lab report on page 151. 9. (Appendix 3) i. The survey points to measure the thickness of each layer of the final cover arenot available on the attached drawing sheets. ii. The partial closure activities were not completed until March 09, 2020(Referring Section 2.2), but the as-built survey was certified by the licensedsurvey dated October 10, 2019. Why the as-built survey is permissible? Please contact me if you have any question of the comments.

The Section informed the Cobles via e-mail message dated June 24, 2020 with comments listed below. Section comments are repeated as they appeared on the June 24, 2020 email, and our responses to the comments are in bold font for clarity and ease of reading. After completing a review of the June 2020 CQA report (FID 1416315) for a partial closure of the Coble’s C&DLF, Permit No. 0105-CDLF-1998, the Solid Waste Section has several comments below. Please respond the comments in writing and submit a final CQA report for this 5.6-acre partial closure activity and the revised permit renewal application for Phase 1 thru 3 of the C&DLF including and the rule-required financial assurance mechanism before July 24, 2020.

Note in the permit modified the waste footprints of Phase 1, 2A and 2B. The perimeter road is constructed in the approved waste footprint of Phases 1 (0.5 acres), 2A (0.1 acres), and 2B (0.2 acres). Since no waste has ever been disposed underneath the perimeter road, the areas occupied by the road (approximately 0.8 acres in total) are excluded from the originally approved waste footprint of 66.8 acres (DIN 24357). 2. (Section 2.2) This Section states that “the surveyor verified the existing intermediate cover thickness to be a minimum of 12 inches prior to Coble commencing the construction of low permeability infiltration soil layer.” There are no survey data in Appendix 3 to confirm that the thicknesses of intermediate cover over the 5.6-acre closure area meet the specified requirement. Please provide survey data. Paragraph 2.2 has been revised to state the intermediate layer is part of the operational cover and in order to ensure adequate thickness of the closure cap, Coble constructed the infiltration and cover soil layers thicker than required. The existing intermediate cover thickness was verified and surface was surveyed to establish base grade for the infiltration layer construction. 3. (Section 2.2.1) According to the CQA plan (including Table 1) and Technical Specifications of the approved Phase 3 PTC application dated March 2008 (DIN 4862), the report does not include the following testing results: i. Construction and QA/QC testing results associated with the test pad of the 18- inch-thick infiltration layer [Sections 02218 & 02229 of the approved Technical Specifications (DIN 4862)]. Phase 3A partial closure continued the partial closure of the C&D LF, and Coble continued in 3A closure using the same soil material as in Phases 1 and 2 closure. As a practical matter, each acre first lift meeting permeability requirement was treated as test pad. ii. Please explain the discrepancy of number of tests described in Section 2.2.1 and those shown in Appendices 1 & 2. Test item Section 2.2.1 Appendices 1 & 2 K, from Shelby tube 18 18 K, from remold sample 2 1 PI NA 1 Standard Proctor NA one point method - 1 In-place density & moisture content (nuclear gauge) 30 106 tested and 96 passed In-place density & moisture content (drive cylinder) 18 21 tested and 19 passed 3 Paragraph 2.2.1 has been revised to eliminate discrepancy in testing iii. The Engineering Plan and Technical Specification Sections 02224 & 02227 and Table 1 (DIN 4862) require the final soil cover system pertaining a minimum friction angle of 26.6 degree by ASTM D4767. Please provide the testing result in the CQA report. March 2008 CQA Plan, Table 1 ASTM 4767 one/material for cap construction, unless otherwise approved by engineer. Phase 3A partial closure continued the partial closure of the C&D LF Phases 1 and 2, and Coble continued using the same soil material for the 3A closure. The CQA engineer accepts test results of previously approved material for the subsequent sections continuing closure work. 4. (Section 2.2.2) The results of testing, per requirement listed in Table 1(DIN 4862), on the protective soil layer/erosion layer are not available in the CQA report. Please provide the test results. The infiltration layer testing is required, but protective cover layer field-testing is not required in Table 1. The protective cover soil was spread in two lifts and tracked up and down the slope with the dozer and compactor to achieve a nominal compaction, so that vegetation can develop a proper root system deep in the soil, as stated in the Section B. Engineering Plan, Final Cover System - c. Protective / Erosion Layer. 5. (Section 2.2.3) i. The gas well diameter and the depth deviate from the approved ones (DIN 17384). Please explain who approves the deviation and why the approval is acceptable by the Solid Waste Section. The gas vents were installed according to the 2012 approved method by excavation. When DIN 17384 was approved, Coble having larger pipe on hand asked permission to use larger vent pipe, but this time for 3A closure Coble installed the six-inch vent pipes to comply with the Section approved standard pipe size for LFG vents. ii. This Section states that “for the Phase 3A closure, Coble installed six passive gas vents in a C&D landfill, excavated pits thru the cover and infiltration layers to place perforated PVC pipes in the top layer of the waste.” Additionally, the photos in Appendix 2 clearly show that areas for installing gas vent were excavated after the final soil cover was completed installed. The gas vent construction destroys the constructed soil cover; therefore, the soil testing (including, but not limited to in-pace density & moisture content and hydraulic conductivity) on each lift per layer must be properly conducted to demonstrate the final cover is successfully restored. The excavated infiltration soil was replaced in the pit around the gas vent and compacted with the backhoe bucket. Cover soil was graded and tracked with dozer to restore the closure surface. By restoring the infiltration and protective cover with the 4 excavated material additional soil testing is not necessary in restoring the small area around the vent pipe. 6. (Appendix 1, page 9 of 207) i. The maximum dry density for soil sample CL-1 (Lab ID 2020-019-001-001) is 95.6 pcf. Please correct the typo in the summary table including the % of the compaction effort. Requested correction made in the lab testing summary table. ii. According to Table 1 (DIN 4862), the following soil testing at the frequency of one test per 10,000 CY is required, but the Lab testing results are not available in the CQA report. The required tests are: Particle size (ASTM D422 & D1140), soil classification (ASTM D 2487), moisture content (ASTM D2216), PI (ASTM D4318), Standard Proctor (ASTM D698). During the infiltration layer construction field-testing results are continuously compared to existing Proctor data, moisture content, and visual classification. Particle size and plastic index are closely related with permeability results. Due to material consistency and satisfactory permeability testing results of the infiltration layer construction, the referenced verification testing the CQA engineer considered redundant. 7. (Appendix 2, page 137 of 207) The in-place density test results at the Acre 13 (lift 1) & Acre 12 (Lift 3) that are summarized in Field Daily Report dated 11/26/14 failed to meet the specified compaction effort - 95% maximum dry density. The referenced testing satisfied permeability requirement thus the engineer accepted the field compaction result below 95%. 8. (Appendix 2, page 150-151) i. The in-place density test results at the Acre 13 (lift 3) are failed to meet the specified compaction effort - 95% maximum dry density. The referenced testing satisfied permeability requirement thus the engineer accepted the field compaction result below 95%. ii. The density results of sample DC-1 showed on the summary table are inconsistent to those in lab report on page 151. Requested correction has been made in the lab testing summary table. 9. (Appendix 3) i. The survey points to measure the thickness of each layer of the final cover are not available on the attached drawing sheets. 5 Surveyor revised drawings as requested. ii. The partial closure activities were not completed until March 09, 2020 (Referring Section 2.2), but the as-built survey was certified by the licensed survey dated October 10, 2019. Why the as-built survey is permissible? Surveyor revised the date as requested.

Page 1 LaBella Associates C&D LF Partial Closure July 2020 CQA Certification Report 1.0 INTRODUCTION This report, prepared by LaBella Associates (LaBella) on behalf of Cobles Sandrock, Inc. (Cobles) addresses the quality assurance procedures and activities conducted during partial closure construction of the Phase 3A at the Cobles C&D landfill in Alamance County, North Carolina. The documents comprising this report were compiled for the C&D landfill closure construction with North Carolina Solid Waste Management Regulations, 15A NCAC 13B and the Phase 3 Permit to Construct # 01-05. Landfill partial closure report submitted to the Solid Waste Section by Joyce Engineering, Inc. (now LaBella Associates) in August 2013 included 11 areas of the landfill Phases 1 and 2 in total area of 9.8 acres. Parts of Phase 1 and 2 west side toe area were subtracted from closure in 2014 to reduce the closure to 9.13 acres. This report covers the continuing closure construction Coble has completed in areas 12 thru 17 of the Phase 3A during 2014, 2016, 2019, and 2020. This report covers 5.6 acres of closure. Cobles acted as the General Contractor and performed all closure construction earthwork during the period from 2014 through 2020. LaBella provided third party construction quality assurance program services. Geotechnics assisted LaBella in the field soil testing and collected samples for soil materials laboratory testing. The soils laboratory testing was conducted at Geotechnics, Inc. in Raleigh, NC. Allred Land Surveying of Snow Camp, NC provided survey for the Phase 3A partial closure. 2.0 CONSTRUCTION QUALITY ASSURANCE PROGRAM 2.1 Roles and Responsibilities Cobles retained LaBella to provide construction quality assurance during the Phase 3A landfill partial closure construction. As an independent consultant from the Owner/Contractor, LaBella, along with the construction field representative Geotechnics provided documentation of the infiltration layer construction. A representative of Geotechnics visited the site to follow the closure work progression by testing each acre-lift in the field compaction and collecting soil samples for laboratory permeability testing. Coble retained a surveyor to provide periodic survey of the work to establish and maintain lines and grades. 2.2 Earthwork Coble continued the landfill partial closure construction in April 2014 by grading Area 12 on north side of the landfill Phase 3A to prepare for closure. The existing intermediate cover surface was surveyed to establish base grades prior to Coble commencing the Cobles Sandrock, Inc. Page 2 LaBella Associates C&D LF Partial Closure July 2020 CQA Certification Report construction of low permeability infiltration soil layer. The surveyor verified the intermediate cover layer thickness in random locations presented in the drawing titled “Intermediate Layer Boring Checks.” The intermediate layer is part of the operational cover and in order to ensure adequate thickness of the closure cap, Coble constructed the infiltration and cover soil layers thicker than required. The total section thickness of the infiltration and vegetative layer section is a minimum of three feet. Following the grading and survey of the intermediate cover, Coble proceeded with low permeability soil infiltration layer construction. Area 12 closure construction was finalized in November 2014. Area 13 closure work began in October 2016 and the work was completed in December 2016. Coble continued Areas 14, 15 and 16 closure as part of the Phase 3A partial closure in 2019. In 2020 Coble finished the 3A partial closure work completing the area 17. Total of the areas 12 thru 17 closure is 5.6 acres. The work was conducted utilizing the landfill heavy equipment; excavator, track loader, compactor, and truck or a pan to deliver the soil to each area under closure construction. 2.2.1 Infiltration Layer Testing and Results Construction soil samples were collected and submitted to laboratory testing for identifying index properties of the soil proposed for the landfill partial closure work in 2013. The laboratory testing results are compiled in Appendix 1. The field-testing of each lift included moisture and density testing with nuclear methods, and a drive cylinder test to verify the nuclear gauge readings. Two Shelby tubes were pushed into the soil to collect undisturbed soil samples of the low-permeability material for laboratory testing. At the beginning of each closure area, Coble constructed the first lift and treated it as a test pad. With satisfactory permeability results, the closure could proceed to the next lift construction. The infiltration layer was constructed in three lifts, each a minimum of six inches in compacted thickness. The field testing records of the infiltration layer construction including nuclear gauge testing, drive cylinder, undisturbed permeability sample (Shelby tube), and daily field reports are included in Appendix 2. Soil infiltration layer construction CQA testing included in-place wet density, moisture content by nuclear method (ASTM D6938), calculated dry density and percent compaction with a Troxler Model 3440 portable nuclear gauge. A density of soil in place by drive cylinder method (ASTM D 2937) was used to collect a sample of soil to verify the nuclear gauge test results for each acre lift. If the nuclear gauge moisture readings were found to deviate significantly from the moisture percentage by direct heating method, the dry density and in- place compaction percentage were re-calculated to verify compaction of the soil. If the placed soils were found not to meet the specification in a given area, Coble was informed of the test results and asked to re-work the soil. Following the soil re-work, the area was subjected to CQA testing verification. With satisfactory nuclear gauge readings at the randomly selected test locations the CQA field personnel pushed a drive cylinder to collect Cobles Sandrock, Inc. Page 3 LaBella Associates C&D LF Partial Closure July 2020 CQA Certification Report the moisture-density verification sample and a Shelby tube to collect the undisturbed sample for laboratory hydraulic conductivity test (ASTM D5084). The partial closure construction was divided into areas each approximately one acre in size to track the construction and field-testing. The field and laboratory testing included 3-acre lifts. Each lift was tested at a minimum of five randomly selected locations by nuclear method, one drive cylinder, and one Shelby tube. The infiltration layer testing results met the moisture-compaction with the permeability requirement. Appendix 1 includes laboratory testing results and summary table. 2.2.2 Protective Cover – Erosion Layer An 18-inch thick protective cover soil layer was placed over the completed infiltration layer. The soil was spread in two lifts and tracked up and down the slope with the dozer and compactor to achieve a nominal compaction so that vegetation can develop a proper root system deep in the soil. Following placement of the erosion layer, the closed side slopes were seeded to establish a vegetative cover during 2020 growing season. 2.2.3 Passive Gas Vents Due to C&D LF waste content, drilling using traditional bucket auger methods for the construction of passive gas vents is impossible. This installation modification to the landfill gas vents was submitted October 1, 2012 to the SWS for review and approval (Section authorization was given on October 9, 2012, Doc. ID 17384). For the Phase 3A closure, Coble installed six passive gas vents in the C&D landfill, excavated pits thru the cover and infiltration layers to place perforated PVC pipes in the top layer of the waste. The 6-inch perforated segment of the vent pipes were installed in waste to a minimum depth of 6 feet below the infiltration cap. Coble used for the excavation a backhoe, and filling it with #57 stone. The excavated low-permeability soil was then replaced back in the pit and compacted tamping with the excavator bucket to close the infiltration layer. Protective soil was replaced and graded over the worked area to provide a continuous layer of the closure cover. 2.2.4 Construction Survey Coble retained Jeff Allred Land Surveying of Snow Camp, NC to provide survey for the landfill partial closure work. After grading the intermediate cover, the prepared surface was surveyed. The surveyor verified the intermediate cover layer thickness in random locations presented in the drawing titled “Intermediate Layer Boring Checks.” The top of intermediate cover thus served as base grades for the infiltration layer construction. At the completion of the three lifts of infiltration layer a minimum of 18-inches in thickness, the surface was then graded and surveyed. Protective cover a minimum of 18-inches in thickness was placed over the infiltration layer. Once again, Coble graded the surface to final grades and the surface was surveyed. The three surveys and the survey data point records are included in Appendix 3. Cobles Sandrock, Inc. Page 4 LaBella Associates C&D LF Partial Closure July 2020 CQA Certification Report The infiltration layer thickness meets or exceeds the minimum required thickness of 1.5 feet. In order to ensure adequate thickness of the infiltration layer and closure cap, some areas were constructed thicker than required. The total section thickness of the infiltration and protective cover soil layer section is a minimum of three feet. Coble used the same soil material for both layers and this report reflects our acceptance of the extra clay layer thickness replacing possible shortage of erosion layer in certain areas. In LaBella’s professional opinion, this condition will not compromise the performance of the cap in any way nor be detrimental to the establishment of grass or long-term maintenance of the cover. The closure of areas 12, 13, 14, 15, 16 and 17 construction was conducted on assumed acre basis on 6 acres. The closure construction survey encompasses total area of 5.6 acres. The C&D landfill partial closure report for phases 1 and 2 August 2013 included 11 areas equaling 9.13 acres. This report covers partial closure of the Phase 3A C&D landfill of 6 areas equaling 5.6 acres. Total areas closed to date encompasses 9.13 + 5.6 = 14.73 acres based on the combined closure surveys. Financial assurance will be revised based on the reported acreage of closure and remaining active area. END OF REPORT Project 2191087.00.02 LaBella Associates, P.C.

This plan includes drawings, which present the long-term, general design concepts related to construction, operation, and closure of the C&DLF unit(s). Additional solid waste management activities located at the C&DLF facility are identified in the plan to meet the requirements of the SWMP .0537 Subchapter. The facility plan defines the waste stream proposed for management at the C&DLF facility, different types of landfill units or non-disposal activities included in the facility design, and describe general waste acceptance procedures. The facility will accept construction and demolition (C&D) debris, and other wastes similar to those typically found in the accepted waste streams such as roofing shingle waste from the manufacturer, waste building materials from mobile home manufacturers and wooden pallets for disposal. No municipal solid waste, hazardous waste, industrial waste, liquid waste, or waste not characterized as LCID or C&D, shall be accepted for disposal. II - Facility Plan Labella Associates, PC. C&D LF 5-Year Permit Renewal/LOS August, 2019 Coble Sandrock, North Carolina Revised July 2020 2 The areal limits of the C&DLF unit(s), total capacity of the C&DLF unit(s), and the proposed waste stream must be consistent with the Division's approval set forth in accordance with Rule .0536 (a)(1). Revised Facility and Engineering Plans Drawings (FP-01, FP-02 and EP- 04, EP-05) provide the information required in Section .0537(d). 1. Waste Stream Types of Waste Specified for Disposal: Only construction/demolition debris will be accepted at the C&D landfill. Construction and demolition debris defined in NC General Statutes is waste or debris resulting solely from construction, remodeling, repair, or the demolition of pavement, buildings, or other structures. Service Area: The Alamance County Franchise Agreement, provided in Appendix 1, limits the service area to be served by the Coble’s Sandrock Landfill to customers within 25 miles from the site. Existing customers outside the 25-mile service limitation are grandfathered under the Franchise Agreement and Coble's Sandrock may continue to accept wastes from these customers. Coble's Sandrock may also accept waste from new customers outside the 25-mile service area to replace existing customers outside the service area; however, first priority in terms of disposal capacity is to be given to waste generated within Alamance County. The Counties from which the facility has previously taken waste include Alamance, Cabarrus, Caswell, Chatham, Davidson, Forsyth, Green, Guilford, Lee, Orange, Randolph, Rockingham, and Wake. Alamance County recognizes that the Coble Sandrock C&D landfill currently accepts waste from customers outside the 25-mile radius, and these existing customers are grandfathered under the Franchise Agreement. New customers outside the 25-mile radius may be accepted to replace the existing customers in accordance with Section 4 of the Franchise Agreement. Segregation Management Procedures: Recyclable material will be segregated from the waste stream and temporarily stored in containers or stockpiles prior to removal from the site. Recyclable material may include wood, metals, concrete, plastic, cardboard, and other materials with appropriate recycling markets. Scrap metal is removed from the site frequently and taken to a metal recycling facility. Cardboard is stored in a 40-yard container that is removed from the site by various vendors when full. Coble’s Sandrock deconstructs mobile trailer homes at the working face of the C&D landfill. Identified C&D waste material removed from the deconstruction process is placed into the landfill. The franchise agreement requires monitoring waste and to reject any significant levels of asbestos. The locations of the mobile trailer home deconstruction area and the recyclables storage areas follow the location of the working face as it progresses across the landfill.

Landfill Capacity Overall Facility Life The available airspace for waste, operational cover soil and intermediate cover material for the entire facility is 6,935,903 cy. Assuming that 10% of that volume will be soil, 6,242,313 cy are available for waste material. Utilizing in-place waste density of 1050 lbs/cy, the remaining tonnage capacity of the landfill is 3,277,214 tons. The in-place waste density stated above is within the typical range of densities measured for C&D debris. Based on excerpt from the historical record (Table 1), Coble’s C&D landfilled an average of 14,004.85 tons/year during the previous five-year period 2016-2020; cumulative in-place waste volume as of July 2020 is 719,433 tons or 1,131,537 cy. Using the recent five-year landfilled average, the remaining capacity calculates approximately 124,426 cy until 2024 in the permitted Phases 1-3A (1,255,963 cy). Subsequently, when permitted to operate, Phase 3B added capacity 349,213 cy, the full date for Phases 1-3B is estimated until 2037 (1,605,176 cy).

The perimeter road is constructed in the approved waste footprint of Phases 1 (0.5 acres), 2A (0.1 acres), and 2B (0.2 acres). Since no waste has ever been disposed underneath the perimeter road, the areas occupied by the road (approximately 0.8 acres in total) are excluded from the originally approved waste footprint of 66.8 acres (DIN 24357). The gross capacities were not reduced from the originally permitted volumes. On the next page Table 1. Future Tonnage Projections are based on recent five-year average tonnage landfilled.

Cumulative volume includes weekly cover soil. Utilization factor 0.53 is representative for the industry . Future phases 4-8 approved for development require permits to construct and operate. Overall Facility Soil Balance The base grading plan, including access roads, for the entire remaining facility yields a net 1,537,784 cy of cut. Approximately 325,871 cy of soil will be needed for final cap (3 feet thick) construction. Assuming 10% of the permitted landfill volume 693,590 cy of soil will be needed for cover soil material. Subtracting the estimated soil requirements from the calculated available material leaves an excess of 518,323 cy of soil. Phase 3B To evaluate the air space requirement for a 5-year phase, assuming an average annual tonnage of 14,004.85 tons/year, the projected total tonnage for the next 5-year phase is 70,024 tons. Assuming an average (UF 0.53 tn/cy) annual consumed air space of 37,112 cy/year, the projected annual volume for next 5-year phase would be 185,564 cy. Closure II - Facility Plan Labella Associates, PC. C&D LF 5-Year Permit Renewal/LOS August, 2019 Coble Sandrock, North Carolina Revised July 2020 6 cap soil volume for 3B is estimated 28,072 cy. Phase 3B permitted gross capacity is 349,213 cu. Assuming the waste disposal at the recent five-year average rate, the capacity would be reached some time during 2037 as shown in the Table 1. Phase 3B has been under construction and the grading was completed in June 2019. In order to keep active working face under 4 acres in accordance with the Permit to Operate, Coble postpones the Phase 3B application of 5.8 acre footprint until later date. At that time the 3B Construction report will be submitted to the Section for review and issuance for Permit to Operate. 3. Special Engineering Features Containment and Environmental Control Systems Cap System: The cap system is described from bottom to top in the following paragraphs. Infiltration Barrier: The infiltration barrier is proposed to consist of either (1) 18 inches of compacted soil with a permeability no greater than 1x10-5 cm/sec; or (2) a geosynthetic clay liner. The low-permeability soil barrier, or the GCL, will lie directly above an intermediate soil cover layer of at least 12 inches in thickness. GCL stability analysis and specifications are included in Appendix 2 of this Plan. Erosion Control Components (Protective Layer and Erosion Layer): A protective layer consisting of at least 12 inches of local soil will be placed on top of the infiltration barrier. The erosion and protective layers will not be heavily compacted to promote vegetative growth. Vegetative Cover: After placement of the protective layer, the area that has been closed will be seeded with a grass mixture. Mulch and erosion control matting will be used as needed to further minimize erosion and promote vegetative growth. Leachate Management Systems: Leachate collection and management systems are not designed or permitted for this construction and demolition unlined waste disposal facility. Base Liner Systems: The base of the landfill is excavated to designed base grades and remaining native soil will serve as the base of the landfill, with the condition that the upper two feet of the base soils consist of the following soil types: SC, SM, ML, CL, MH, or CH (according to Unified Soil Classification System). II - Facility Plan Labella Associates, PC. C&D LF 5-Year Permit Renewal/LOS August, 2019 Coble Sandrock, North Carolina Revised July 2020 7 Gas Management System: Passive gas vents will be installed to a minimum depth of 10-feet below surface in the waste mass at a frequency of one vent per acre. 4. Partial Closure of the Landfill The west side of the landfill Phases 1 and 2 Coble closed in 2012-2013 and the CQA report was submitted to the Section in August 2013. Coble continued the partial closure of Phase 3A in the areas 14 thru 17 since 2014 and completed the work in 2020. At completion of the closure efforts, the partial closure CQA report includes the areas 12-17. Partial closure surveys are included in the Figures attachment of this Plan. The financial assurance for the C&D landfill will be revised in accordance with rule .01628.

Description of Cap System: The cap system to be used is designed to minimize infiltration and erosion. The cap system will consist of: • A low-permeability infiltration layer of at least 18 inches with a permeability not greater than 1.0 x 10-5 cm/sec; or geosynthetic clay liner (GCL); • An erosion layer that contains a minimum of 12 inches of earthen material that is capable of sustaining native plant growth. Approved Alternate Cover Material (ACM) mulch/soil mixture in accordance Operations Plan Section 4 Cover Materials Requirements. Construction of the cap system was prepared in accordance with Rule .0540 of this Section and the following requirements: (A) post-settlement surface slopes will be a minimum of five percent and a maximum of 33 percent; and (B) a gas venting or collection system will be installed below the low- permeability barrier to minimize pressures exerted on the barrier. The construction of the closure cap will be in accordance with the Volume 2 Application for Permit to Construct Phase 3 and the specifications provided in Appendix IV. The Application to Construct Phase 3 was approved by the SWS on 2/19/2009. Procedures for Cap Installation The construction of the cap will be in accordance with the specifications provided in Appendix IV. 2. Closure Area Portions of Phases 1, 2A/B and 3A are active for landfill operations. Summary table below shows current status of the landfill phases open and closed acreages. Active landfill closure applies to the top area of Phases 1 and 2A/B piggyback and 3A.

The perimeter road is constructed in the approved waste footprint of Phases 1 (0.5 acres), 2A (0.1 acres), and 2B (0.2 acres). Since no waste has ever been disposed underneath the perimeter road, the areas occupied by the road (approximately 0.8 acres in total) are excluded from the originally approved waste footprint of 66.8 acres (DIN 24357). 3. Waste Inventory As of July 2020 annual facility reporting, the cumulative tonnage received and landfilled was 719,433 tons since the beginning of operations (1999). At an average density of 1050 pounds/cubic yard, this equates to approximately 1,131,537 cubic yards of consumed airspace. 4. Schedule The Phases 1, 2 and 3A permitted capacity is 1,255,963 cy. Subtracting current approximately consumed 1,131,537 cy of airspace, the balance is estimated 124,426 cubic yards. The three-foot thick closure cap is expected to consume 4,840 cy/acre. Following landfill Phase 1 and 2 closure of 9.13 acres and Phase 3A closure of 5.6 acres, the remaining active area shown in the above table is approximately 3.7 acres. The remaining area to be closed is expected to take 17,910 cy reducing landfilling airspace (124,426 – 17,910) to 106,516 cubic yards. Based on the recent five-year landfilled average of 26,676 cu/year the remaining airspace is estimated 4 years or some time in 2024. Prior to beginning final closure, Coble’s Sandrock must notify the Division that a Notice of Intent to close the facility has been placed in the operating record. Phase 3B is pending completion and permit to operate (PTO). Phases 4 through 8 approved for future development require submittals of PTC/PTO applications.

Deed Recordation Following closure, the owner or operator will record a notation on the deed to the landfill facility property at the local county Register of Deeds office, or some other instrument that is normally examined during title search, and notify the Division that the notation has been recorded and a copy has been placed in the operating record. The notation on the deed shall in perpetuity notify any potential purchaser of the property that the land has been used as a C&D landfill unit or facility and its use is restricted under the closure plan approved by the Division. POST CLOSURE Post-closure activities must be conducted at the landfill for a period of 30 years following closure of the landfill. However, the length of the period can be increased or decreased in accordance with Division directives. 1. Contact Coble’s Sandrock, Inc. will handle questions and/or problems, which might occur during the post-closure care period. CONTACT PERSON: Mr. Kent Coble OWNER: Mr. Kent Coble ADDRESS: 5833 Foster Store Road Liberty, North Carolina 27298 PHONE NUMBER: (336) 565-4750 FAX: (336) 565-4752 2. Security Control access to the site by the use of barriers and gates at roadway entrances. Maintain these control devices throughout the post-closure care period, and inspected as part of the monthly inspection program. Mark all barriers and gates clearly with signs stating the name and nature of the facility and the person to contact in case of emergency or breach of security. 3. Post-Closure Maintenance Post-closure maintenance and monitoring will be conducted at the landfill for a period of 30 years after final closure. The Division may decrease the length of the post-closure period if the owner or operator demonstrates that the reduced period is sufficient to protect human health and the environment, and the Division approves this demonstration. The period might be increased by the Division if the Division determines that the lengthened period is necessary to protect human health and the environment. V – Closure & Post-Closure Care Plan Labella Associates, PC C&D LF 5-Year Permit Renewal/LOS 6 August 2019 Coble’s Sandrock, North Carolina Revised July 2020 Monitoring will include semi-annual sampling of groundwater and surface water, quarterly gas monitoring, and quarterly inspection of the final cover and monitoring and control systems. Maintenance needs identified through the monitoring program must be initiated no later than 60 days after the discovery, and within 24 hours if a danger or eminent threat to human health or the environment is indicated. Minor cap maintenance may be deferred until there is a sufficient amount of work to justify the mobilization of equipment and personnel. Add soil to the cap as necessary to correct the effects of settlement and subsidence of the landfill and to prevent run-on and run-off from eroding the final cap. Protect and maintain stormwater control devices, surveyed benchmarks, groundwater monitoring wells, surface water monitoring/sampling gauges and LFG wells. If seeps are discovered, an investigation of why there is a seep and if the cap integrity has been compromised shall be performed. If the clay cap has released leachate the cap will be repaired and recompacted to closure CQA required levels and the vegetative layer will be reestablished. Mow vegetation twice per year. Cost for routine maintenance assumes 10% of the cap area will require reseeding and fertilizing each year. Maintain and repair security fencing, gates, and access roads as necessary. 4. Inspection Plan Routine inspections will be conducted throughout the post-closure care period. These inspections will be carried out quarterly unless problems are detected that indicate that more frequent visits are warranted. Potential impacts to the public and environment will be considered in determining the inspection frequency. Items to be included in the monthly inspection will be as follows: • Access and security control, • Stormwater management, • Erosion and sediment control, • Edge markers of the landfill waste footprint/disposal boundary, • Gas management, • Groundwater and landfill gas monitoring systems, and • Vector control. The quarterly inspections will be carried out by someone properly trained and knowledgeable about landfills, such as the landfill owner, operator or engineering consultant. The results of the inspections will be documented in Post Closure Inspection Form. If inspections indicate that repairs are necessary, repairs will be initiated as soon as practicable. If a leachate seep or outbreak is observed in the routine inspection tasks as noted in Appendix B, a verbal notice to the SWS within 24 hours and within 15 days a written V – Closure & Post-Closure Care Plan Labella Associates, PC C&D LF 5-Year Permit Renewal/LOS 7 August 2019 Coble’s Sandrock, North Carolina Revised July 2020 notification with the assessment sampling plan must be submitted to the SWS. The leachate releases assessment/sampling guidance that can be found in the following web link should be appended to the plan: https://edocs.deq.nc/gov/WasteManagement/0/edoc/1319075/MSW%20Leachate_Relea ses_Sampling_Guide.pdf?searchid=22b91c58-be48-4f48-97ecae3766e88565 In addition to the routine quarterly inspections, special inspections will be performed and documented after events, which may cause damage to the integrity of the landfill cover, such as heavy rainfall. Inspection may also be necessary following written or verbal complaints, vandalism or fires. Following special inspections, any necessary repairs will be initiated as soon as practicable. Maintain records of all inspections in the operating record. 5. Post-Closure Land Use The primary land use for the site after closure of the landfill will be open dormant green space. No raising of animals shall be allowed after final closure per Rule 15A NCAC 13B .0543(f)(3) without written approval of DEQ. 6.

(Section 2.2) This Section states that “the surveyor verified the existing intermediate cover thickness to be a minimum of 12 inches prior to Coble commencing the construction of low permeability infiltration soil layer.” There are no survey data in Appendix 3 to confirm that the thicknesses of intermediate cover over the 5.6-acre closure area meet the specified requirement. Please provide survey data. 3. (Section 2.2.1) According to the CQA plan (including Table 1) and Technical Specifications of the approved Phase 3 PTC application dated March 2008 (DIN 4862), the report does not include the following testing results: i. Construction and QA/QC testing results associated with the test pad of the 18-inch-thick infiltration layer [Sections 02218 & 02229 of the approved Technical Specifications (DIN 4862)]. ii. Please explain the discrepancy of number of tests described in Section 2.2.1 and those shown in Appendices 1 & 2. Test item Section 2.2.1 Appendices 1 & 2 K, from Shelby tube 18 18 K, from remold sample 2 1 PI NA 1 Standard Proctor NA one point method - 1 2 In-place density & moisture content (nuclear gauge) 30 106 tested and 96 passed In-place density & moisture content (drive cylinder) 18 21 tested and 19 passed iii. The Engineering Plan and Technical Specification Sections 02224 & 02227 and Table 1 (DIN 4862) require the final soil cover system pertaining a minimum friction angle of 26.6 degree by ASTM D4767. Please provide the testing result in the CQA report. 4. (Section 2.2.2) The results of testing, per requirement listed in Table 1(DIN 4862), on the protective soil layer/erosion layer are not available in the CQA report. Please provide the test results. 5. (Section 2.2.3) i. The gas well diameter and the depth deviate from the approved ones (DIN 17384). Please explain who approves the deviation and why the approval is acceptable by the Solid Waste Section. ii. This Section states that “for the Phase 3A closure, Coble installed six passive gas vents in a C&D landfill, excavated pits thru the cover and infiltration layers to place perforated PVC pipes in the top layer of the waste.” Additionally, the photos in Appendix 2 clearly show that areas for installing gas vent were excavated after the final soil cover was completed installed. The gas vent construction destroys the constructed soil cover; therefore, the soil testing (including, but not limited to in-pace density & moisture content and hydraulic conductivity) on each lift per layer must be properly conducted to demonstrate the final cover is successfully restored. 6. (Appendix 1, page 9 of 207) i. The maximum dry density for soil sample CL-1 (Lab ID 2020-019-001-001) is 95.6 pcf. Please correct the typo in the summary table including the % of the compaction effort. ii. According to Table 1 (DIN 4862), the following soil testing at the frequency of one test per 10,000 CY is required, but the Lab testing results are not available in the CQA report. The required tests are: Particle size (ASTM D422 & D1140), soil classification (ASTM D 2487), moisture content (ASTM D2216), PI (ASTM D4318), Standard Proctor (ASTM D698). 7. (Appendix 2, page 137 of 207) The in-place density test results at the Acre 13 (lift 1) & Acre 12 (Lift 3) that are summarized in Field Daily Report dated 11/26/14 failed to meet the specified compaction effort - 95% maximum dry density. 8. (Appendix 2, page 150-151) i. The in-place density test results at the Acre 13 (lift 3) are failed to meet the specified compaction effort - 95% maximum dry density. ii. The density results of sample DC-1 showed on the summary table are inconsistent to those in lab report on page 151. 9. (Appendix 3) i. The survey points to measure the thickness of each layer of the final cover are not available on the attached drawing sheets. ii. The partial closure activities were not completed until March 09, 2020 (Referring Section 2.2), but the as-built survey was certified by the licensed survey dated October 10, 2019. Why the as- built survey is permissible? 3 Please contact me if you have any question of the comments.         From: Chao, Ming‐tai   Sent: Friday, June 19, 2020 2:57 PM  To: Deanna Coble Martin <deanna@coblesinc.com>  Cc: Kirchner, Chuck <chuck.kirchner@ncdenr.gov>; Stanley, Sherri <Sherri.Stanley@ncdenr.gov>; Kemppinen, Hannu  <HKemppinen@LaBellaPC.com>  Subject: RE: [External] 0105‐CDFL‐1998 2020619 Phase 3A Partial closure Report    Dear Mrs. Martin: The Solid Waste Section receives the electronic copy of the CQA report for Phase 3A partial closure; this report is uploaded to Laserfiche with a FID 1416315.

Page 1 LaBella Associates C&D LF Partial Closure June 2020 CQA Certification Report 1.0 INTRODUCTION This report, prepared by LaBella Associates (LaBella) on behalf of Cobles Sandrock, Inc. (Cobles) addresses the quality assurance procedures and activities conducted during partial closure construction of the Phase 3A at the Cobles C&D landfill in Alamance County, North Carolina. The documents comprising this report were compiled for the C&D landfill closure construction with North Carolina Solid Waste Management Regulations, 15A NCAC 13B and the Phase 3 Permit to Construct # 01-05. Landfill partial closure report submitted to the Solid Waste Section by Joyce Engineering, Inc. (now LaBella Associates) in August 2013 included 11 areas of the landfill Phases 1 and 2 in total area of 9.8 acres. This report covers the continuing closure construction Coble has completed in areas 12 thru 17 of the Phase 3A during 2014, 2016, 2019, and 2020. This report covers 5.6 acres of closure. Cobles acted as the General Contractor and performed all closure construction earthwork during the period from 2014 through 2020. LaBella provided third party construction quality assurance program services. Geotechnics assisted LaBella in the field soil testing and collected samples for soil materials laboratory testing. The soils laboratory testing was conducted at Geotechnics, Inc. in Raleigh, NC. Allred Land Surveying of Snow Camp, NC provided survey for the Phase 3A partial closure. 2.0 CONSTRUCTION QUALITY ASSURANCE PROGRAM 2.1 Roles and Responsibilities Cobles retained LaBella to provide construction quality assurance during the Phase 3A landfill partial closure construction. As an independent consultant from the Owner/Contractor, LaBella, along with the construction field representative Geotechnics provided observation and documentation of the closure earthwork construction. A representative of Geotechnics visited the site to follow the closure work progression by testing each acre-lift in the field and collecting soil samples for laboratory testing. In accordance with the approved CQA Plan, Coble retained a surveyor to provide periodic survey of the work to establish and maintain lines and grades. 2.2 Earthwork Coble began the landfill partial closure construction in April 2014 by grading Area 12 on north side of the landfill Phase 3A to prepare for closure. The surveyor verified the existing intermediate cover thickness to be a minimum of 12 inches prior to Coble commencing the construction of low permeability infiltration soil layer. Cobles Sandrock, Inc. Page 2 LaBella Associates C&D LF Partial Closure June 2020 CQA Certification Report Following the grading and survey of the intermediate cover, Coble proceeded with low permeability soil infiltration layer construction. Area 12 closure construction was finalized in November 2014. Area 13 closure work began in October 2016 and the work was completed in December 2016. Coble continued Areas 14, 15 and 16 closure as part of the Phase 3A partial closure in 2019. In 2020 Coble finished the 3A partial closure work completing the area 17. Total of the areas 12 thru 17 closure is 5.6 acres. The work was conducted utilizing the landfill heavy equipment; excavator, track loader, compactor, and truck or a pan to deliver the soil to each area under closure construction. 2.2.1 Infiltration Layer Testing and Results Pre-construction soil samples were collected and submitted to laboratory testing for identifying index properties of the soil proposed for the landfill partial closure work. The laboratory testing results are compiled in Appendix 1. The field-testing of each lift included moisture and density testing with nuclear methods, and a drive cylinder test to verify the nuclear gauge readings. Two Shelby tubes were pushed into the soil to collect undisturbed soil samples of the low-permeability material for laboratory testing. The infiltration layer was constructed in three lifts each a minimum of six inches in compacted thickness. The field testing records of the infiltration layer construction including nuclear gauge testing, drive cylinder, undisturbed permeability sample (Shelby tube), and daily field reports are included in Appendix 2. Soil infiltration layer construction CQA testing included in-place wet density, moisture content by nuclear method (ASTM D6938), calculated dry density and percent compaction with a Troxler Model 3440 portable nuclear gauge. A density of soil in place by drive cylinder method (ASTM D 2937) was used to collect a sample of soil to verify the nuclear gauge test results for each acre lift. If the nuclear gauge moisture readings were found to deviate significantly from the moisture percentage by direct heating method, the dry density and in- place compaction percentage were re-calculated to verify compaction of the soil. If the placed soils were found not to meet the specification in a given area, Coble was informed of the test results and asked to re-work the soil. Following the soil re-work, the area was subjected to CQA testing verification. With satisfactory nuclear gauge readings at the randomly selected test locations the CQA field personnel pushed a drive cylinder to collect the moisture-density verification sample and a Shelby tube to collect the undisturbed sample for laboratory hydraulic conductivity test (ASTM D5084). The partial closure construction was divided into areas each approximately one acre in size to track the construction and field-testing. The field and laboratory testing included 3-acre lifts. Each lift was tested at a minimum of 5 randomly selected locations by nuclear method, one drive cylinder and one Shelby tube. A total 30 nuclear tests, 18 drive cylinders and 18 low-permeability tests were performed. The infiltration layer testing results met the Cobles Sandrock, Inc. Page 3 LaBella Associates C&D LF Partial Closure June 2020 CQA Certification Report moisture-compaction and the permeability requirement. Appendix 1 includes laboratory testing summary table. 2.2.2 Protective Cover – Erosion Layer An 18-inch thick protective cover soil layer was placed over the completed infiltration layer. The soil was spread in two lifts and tracked up and down the slope with the dozer to achieve a nominal compaction of about 90 percent so that vegetation can develop a proper root system deep in the soil. Following placement of the erosion layer, the closed side slopes were seeded to established a vegetative cover during 2020 growing season. 2.2.3 Passive Gas Vents Due to C&D LF waste content, drilling using traditional bucket auger methods for the construction of passive gas vents was impossible in 2012. This installation modification to the landfill gas vents was submitted October 1, 2012 to the SWS for review and approval (Section authorization was given on October 9, 2012, Doc. ID 17384). For the Phase 3A closure, Coble installed six passive gas vents in a C&D landfill, excavated pits thru the cover and infiltration layers to place perforated PVC pipes in the top layer of the waste. The 6-inch perforated segment of the vent pipes were installed in waste to a depth 5 to 6 feet below the infiltration cap. The excavated gas vent pit was filled with #57 stone. Low permeability soil was then placed over the stone to close the infiltration layer. Top soil was placed over the worked area to provide a continuous layer of the protective cover. 2.2.4 Construction Survey Coble retained Jeff Allred Land Surveying of Snow Camp, NC to provide survey for the landfill partial closure work. After grading the intermediate cover, the prepared surface was surveyed. The top of intermediate cover thus served as base grades for the infiltration layer construction. At the completion of the three lifts of infiltration layer a minimum of 18-inches in thickness, the surface was then graded and surveyed. Protective cover a minimum of 18- inches in thickness was placed over the infiltration layer. Once again, Coble graded the surface to final grades and the surface was surveyed. The three surveys and the surveys data point records are included in Appendix 3. The infiltration layer thickness meets or exceeds the minimum required thickness of 1.5 feet. In order to ensure adequate thickness of the infiltration layer and closure cap, some areas were constructed thicker than required. The total section thickness of the infiltration and vegetative layer section is a minimum of three feet. Coble used the same soil material for both layers and this report reflects our acceptance of the extra clay layer thickness replacing the shortage of erosion layer in certain areas. In LaBella’s professional opinion, this condition will not compromise the performance of the cap in any way nor be detrimental to the establishment of grass or long-term maintenance of the cover. Cobles Sandrock, Inc. Page 4 LaBella Associates C&D LF Partial Closure June 2020 CQA Certification Report The closure of areas 12, 13, 14, 15, 16 and 17 construction was conducted on assumed acre basis on 6 acres. The closure construction survey encompasses total area of 5.6 acres. The C&D landfill partial closure report for phases 1 and 2 August 2013 included 11 areas equaling 9.8 acres. This report covers partial closure of the Phase 3A C&D landfill of 6 areas equaling 5.6 acres. Total areas closed to date encompasses 9.8 + 5.6 = 15.4 acres based on the combined closure surveys. Financial assurance will be revised based on the reported acreage of closure and remaining active area.
