General Statutes. Further, the facility and/or all responsible parties may also be subject to enforcement actions including penalties, injunction from operation of a solid waste management facility or a solid waste collection service and any such further relief as may be necessary to achieve compliance with the North Carolina Solid Waste Management Act and Rules. FACILITY COMPLIANCE INSPECTION REPORT Division of Waste Management Solid Waste Section Page 2 of 5 dated September 7, 1995. 3. The area adjacent to the closed landfill serves as a convenience center where MSW and C&D waste, white goods, scrap tires, electronics and televisions, used oil, scrap metal, household recyclable materials such as cardboard, plastics and metal cans, and brush and land clearing debris are accepted. The convenience center has signs prominently displayed to direct and inform the public as to materials accepted and disposal locations. 4. All vehicles bringing waste cross the scales upon entering the site. Waste disposal is provided at no charge to Stokes County residents. Businesses using the site are charged a tipping fee. The scale house operator determines whether charges are to be applied to a load, records the weight, and accepts payments. 5. The scale house operator also accepts and approves scrap tire certifications to determine the eligibility of incoming tires for free disposal. Scrap tire certifications for the current calendar year were reviewed and found to be complete. 6. Stokes County currently contracts with the following companies for recycling and disposal of the materials accepted at the convenience center: • New River Tire Recycling – scrap tires; • D. H. Griffin, Inc. – white goods recycling; • Carolina Refrigerant Recover – CFC removal; • Synergy Recycling, LLC – electronics and televisions; • Waste Management – MSW disposal and household recycling. 7. The facility performs the required semi-annual groundwater sampling events on a June and December schedule. Seven monitoring wells are sampled, along with two surface water points and two water supply wells. One of the monitored water supply wells is on a neighboring residential property. Reports covering sampling events for that private well are provided to the property owner and not to Stokes County. Reports for the December 2016 and June 2017 sampling events were verified and reviewed. • The second sampling event of 2016 took place on December 29, 2016. Exceedances of five organic compounds were detected in groundwater monitoring wells; surface water monitoring points and the facility water supply well samples indicated no detections. • The first sampling event of 2017 took place on June 13, 2017. Exceedances of four organic compounds were detected in groundwater monitoring wells; surface water monitoring points and the facility water supply well samples indicated no detections. 8. Landfill gas monitoring began in 2010 and is accomplished through sampling 8 bar hole probe sites and five facility structures on a quarterly basis. All monitoring records, from the program’s inception in 2010 through the latest sampling event on November 29, 2017 were available and reviewed. No exceedances were indicated. 9. All disposal areas are designated by white plastic edge-of-waste markers that are clearly visible. 10. The northern portion of the closed landfill is comprised of Cells 1 and 2, and is the oldest portion of the facility. The top of the landfill had a well-established vegetative cover and appeared to be maintained regularly. At the time of this inspection, repair work was underway on the top of the landfill cap. Mr. Delehant stated that the continual rain and snow events of the season had resulted in an area settling and water accumulating in the resulting depressions. Piles of clean soil had been staged on the landfill top. Mr. France explained that work had stopped due to the recent warm temperatures making the cap soft and muddy. He added that using heavy equipment had become unsafe and destructive to the landfill cap. Mr. France stated his intention to resume the work as soon as the conditions allow. Ensure that repairs to the top of the landfill cap are completed in a timely manner to allow for the sheet flow of storm water off the landfill and to prevent the impoundment of water over waste, as required by the closure permit. 11. Some woody plants, briars and trees were observed in areas of the side slopes of Cells 1 and 2. Most of the trees appeared to be small saplings; however, some trees were mature and exceeded 6” in diameter. Mr. France stated that the slopes would be bush hogged where necessary, the small saplings removed, and the slopes repaired so that the required 24” of soil cover is restored in all areas. Additional clean soil had been stockpiled along the southwest side of cells 1 and 2 and on the top of the adjoining Cell 3 for this purpose, and Mr. France stated his intention to continue maintenance of the side slopes as conditions allow. Ensure that maintenance on the side slopes of Cells 1 and 2 is completed in a timely manner, including the addition of clean soil as needed to achieve the required 24” minimum final cover; and, the seeding of the slopes to establish vegetative cover in areas where it is lacking, as required by 15A NCAC 13B .0505(3)(c) and .0505(6)(a) and (b). FACILITY COMPLIANCE INSPECTION REPORT Division of Waste Management Solid Waste Section Page 3 of 5 12. Mr. Delehant and Mr. France discussed their ongoing plan to manage the trees on the slopes of Cells 1 and 2, stating that any trees over 6” in diameter would be left in place and monitored. If trees were found to be damaged, diseased or dead, they would be removed promptly, along with the stump and root system, and the resulting damage to the cap would be repaired immediately. 13. The southernmost area of the landfill is Cell 3. This is the newest portion of the landfill, having begun accepting waste in 1986. The top of this portion of the landfill is also much lower in elevation than Cells 1 and 2 because it closed in 1994 before being filled to completion. 14. During the previous inspection on August 20, 2009, Cell 3 was observed to be covered in what was described in the inspection report as a pine forest. Since that time, the entire waste disposal area had been cleared and the required soil cover and vegetative cover had been restored on both the top of the landfill and on the side slopes. Vegetative cover was observed to be well-established and well-maintained. Some woody growth was observed in one small area on the top of the landfill cap. Mr. France explained that this vegetative growth was surrounding a slope drain and stated that it would be removed when mowing was able to resume. 15. No erosion or sedimentation was observed in the waste disposal areas. 16. The facility’s groundwater monitoring system is comprised of 10 groundwater monitoring wells, 2 surface water monitoring points and two water supply wells. Three of the groundwater monitoring wells are not currently being sampled, however all of the wells and surface water monitoring points were inspected. All 10 of the monitoring wells were observed to be protected in steel casings set in concrete and fitted with locking caps secured with padlocks. In addition, all the monitoring wells were identified with permanent, rust-proof metal identification plates. Some woody growth was observed sprouting at the base of MW-4. Please ensure that the woody plants and vines observed around the base of MW-4 are removed and that all groundwater monitoring wells are maintained so that they are clear of vegetation and easily accessible. 17. Cells 1, 2 and 3 are served by an all-weather facility access road. Some areas of the road had been damaged by the continuing rain and snow events. Please ensure that maintenance is performed to repair the damaged areas of the access roadway, as required by 15A NCAC 13B .0505(8)(c). 18. Due to soft and muddy conditions at the site, access to some areas was gained on foot so that the facility truck did not damage the landfill roadway and cap system. Some of the monitoring wells and bar hole probe sites are in remote locations that are rarely accessible by vehicle. Discussion ensured concerning the advisability of using a 4-wheeler to inspect the landfills and monitoring system and to perform the landfill gas sampling procedures in lieu of heavy vehicles and equipment. Mr. Delehant expressed his intention to research the purchase of a 4- wheeler for future use at the facility.
