OBSERVED VIOLATIONS: None. FACILITY COMPLIANCE INSPECTION REPORT Division of Waste Management Solid Waste Section Page 2 of 5 ADDITIONAL COMMENTS This facility is permitted to receive solid waste generated by or at the Dan River Steam Station. Waste types include, but are not limited to: coal combustion residuals, wastewater treatment sludge, vacuum truck waste, waste soils (i.e. from ash removal activities or soil that has contacted petroleum), and small quantities of inert debris from CCR unit decommissioning activities. Additionally, de minimis quantities of vegetative material from basin closure may be placed in the landfill. The Permit to Operate shall expire October 26, 2021. 1. The Permit and Operations Plan must be maintained on-site as required and were reviewed during the site inspection. 2. The facility is operated by Parsons Corporation which is responsible for hauling materials to the landfill, daily operations of the landfill, and conducting other associated activities. 3. Ash disposal began on May 31, 2017. For the period between 1/1/18 and 5/16/18, the facility landfilled 322,394.80 tons. Ash continues to be transported by truck to Roanoke Cement for beneficial reuse. 4. No ash was landfilled between 5/17/18 and the date of the inspection because heavy rainfall late afternoon on 5/16/18 caused slope stability concerns on the western side of the landfill. Nearly an inch and a half of rain fell in less than 30 minutes causing water to pool around a chimney drain on the western side of the landfill, and then to break through the perimeter berm. Silting may have reduced the capacity of the chimney drain. The breach pushed a small quantity protective cover soil, vegetative material and CCR material from Cell 2 into the lined perimeter berm ditch. Materials were excavated from the ditch and placed back into the landfill and slope repairs were completed on May 17, 2018. More detailed information can be found in the Duke Energy Environment Monitoring Report dated May 17, 2018. Landfilling of ash from onsite basin and stockpiles resumed on June 18, 2018. Repaired western side slope The item(s) listed above were observed by Section staff and require action on behalf of the facility in order to come into or maintain compliance with the Statutes, Rules, and/or other regulatory requirements applicable to this facility. Be advised that pursuant to N.C.G.S. 130A-22, an administrative penalty of up to $15,000 per day may be assessed for each violation of the Solid Waste Laws, Regulations, Conditions of a Permit, or Order under Article 9 of Chapter 130A of the N.C. 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.

Parsons personnel are responsible for daily landfill operations; certified staff are always present when the landfill is in operation. Training records were documented and maintained on-site. Onsite operations training occurred on 9/26/17. The following Parsons personnel are NC Certified Landfill Managers: James Morning, 17-02M-00296, expires 5/31/2020 Swaine Skeen, 17-02M-00297, expires 5/31/2020 Anton Bantel, 17-020-00293, expires 5/12/2017 John Thomas, 17-020-00291, expires 5/12/2020 6. No concerns were noted with monitoring wells observed during the inspection. 7. Edge-of-waste markers delineating the permitted disposal area were visible and being maintained. The markers are offset from the edge of the landfill liner. 8. All required signs have been posted. 9. Facility access roads are of all-weather construction and are well maintained. 10. Water trucks are utilized to control road in the landfill and on roads. Water trucks were operating at the time of the inspection. Dust control checks occur daily at 9am and 2pm. Records were reviewed during the inspection. 11. Operational cover is being maintained as approved in the facility Operations Plan. Minimal soil is utilized for cover; landfilled materials are moistened and allowed to crust over to prevent windblown material. Additionally, Gorilla Snot can be used to aid in the process of crusting. 12. Daily Observations Checklists were reviewed during the inspection and appear to be complete. A reoccurring note regarding leachate reporting of meters showed “total out of expected range.” This issue may be related to malfunctioning meters or to need for additional staff training regarding reading meters. The issue needs to be resolved. 13. The initial semi-annual ground water, surface water and leachate monitoring samples were taken on 11/2/17 with report in the on-site records. The second semi-annual sampling event occurred May 2018 where a results report will be submitted within 120 days and copy of the report put in the on-site records. The Water Quality Monitoring Plan, Revision 2 dated June 8, 2018 was in the on-site records. 14. Field density reports were reviewed during the inspection and appear complete; density tests which fail are retested. 15. Leachate and contact water generated by the facility is pumped from the landfill sumps to a leachate tank storage facility and ultimately to the City of Eden publically owned treatment works (POTW) for treatment. The City of Reidsville has reissued the industrial users permit (IUP), Permit No. 1013-Discharge permit: Effective 3/1/2018, Expires 2/28/2019. Leachate records were reviewed during the inspection. Leachate pumps have backup generators to continue pumping in the event of a power failure. 16. Leachate system cleaning and flushing was completed between May 29 and 31, 2018. No issues were reported. FACILITY COMPLIANCE INSPECTION REPORT Division of Waste Management Solid Waste Section Page 4 of 5 17. Cells 1, 2 and 3 were active at the time of the inspection. Ash was not being placed in the landfill during the inspection but was being moved within the landfill for drainage and better slope stability. Ash placement prior to the May 16, 2018 incident had created high elevations in the central portions of Cells 1 & 2 such that the sloping was directing the majority of leachate runoff to chimney drains around the perimeter of the landfill. Slopes were being actively recontoured at the time of the inspection. Section staff request that we be notified during periods of unusual operations. 18. Side slopes and inactive areas have soil cover and have been reseeded in areas with inadequate vegetation. Side slopes were well vegetated and are being well maintained. Vegetative growth on side slopes and facility property are mowed regularly every four to six weeks or as needed. No significant erosion was observed. Completed Cell 3 with interior ramp to Cell 2. 19. Additional chimney drains have been installed to facilitate leachate drainage into the collection system. The chimney drain in Cell 2 which was inundated on May 16, 2018 was being reworked to ensure that it functions as designed. 20. Visible windblown dust from landfill operations was noted during the inspection in the highest elevation of Cell 2. Visible ash did not appear to be leaving the footprint of the landfill. Weather conditions during the inspection were dry, sunny and warm (temperatures in the 80s) with a breeze from the southwest. Ensure that the facility is operating according to the approved Dust Control Plan both during times of active operations and during periods of inactivity (e.g. weekends).
