Secondary containments shall be utilized for equipment not in use. Secondary containments shall meet the latest revision of the CCP supplemental. 14. Ace Clearing will clear, grub and remove vegetation within delineated limits of disturbance as shown on the Project Drawings. A dozer and excavator may be used in the removal of the stumps. A tub grinder will be utilized in the grinding operations of the vegetation and a loader or excavator will be utilized to load grubbed material and debris, which will then be hauled to an offsite disposal location. 15. A portion of the NE work area will be cleared and grubbed, in order to provide access for haul truck traffic to the stockpile area. Additional access road work shall commence in order to allow for safe hauling operations. Hold Point – Exclusion zones will be established at the entrance to the project work area to prohibit access to only approved project personnel. During times of high traffic, a dedicated spotter will be stationed at the exclusion zone to direct traffic and review the JHA as needed. Site Development Sediment Basin 16. Once the sediment basin area has been cleared and grubbed, approximately 6,750 CY of soil will be cut and filled in order to begin constructing the access road. 17. A GPS equipped dozer will be utilized to fine grade the internal and external slopes of the sediment to ensure the 3H:1V slope designs are achieved per engineered drawings. 18. As the grading of the sediment basin is commencing, additional features such as the principal spillway, emergency spillway, manhole, skimmer, and baffles, will be installed to support the functionality of the basin. Once substantially complete, seeding will be applied to the sediment basin to assist with erosion and sediment controls. Access Road 19. The excavated soil material from the sediment basin will be utilized as fill to construct the access road. 20. To complete the construction of the access road, approximately 13,500 CY of soil will be excavated from the cut area of Cell 3 and will be hauled, placed and compacted to finalize the design elevations, and the tie-ins, of the access road. A 2H:1V V-ditch will also be created inside the access road to convey stormwater from around the project site to the sediment basin. 21. Once soil hauling and placement activities are completed, woven geotextile will be installed along with surge stone, No. 4 stone, and ABC stone to depths of 6-inch, 3-inch and 3-inch respectively. 22. Additional features, such as numerous culverts, rip rap channel lining, ditch matting, wattles and hydro-seeding shall be installed to ensure the access road is equipped to manage stormwater runoff as designed. Haul Route Marshall – ILF Cells 3 and 4 Landfill Construction 8 23. In order to efficiently haul soil from the landfill construction to the stockpile modifications are needed to construct a new access road to the stockpile. 24. Once the area NE of the project has been cleared and grubbed, grading shall commence to begin prepare the subgrade for the new access road. The road will be constructed an approximate 30-foot width to allow for safe two-way traffic. 25. Once grading activities are completed, woven geotextile will be install, along with stone, to create an all-weather access to the stockpile area. Refer to Attachment B for layout details regarding the new access road alignment. Cell Construction Cell 3 Construction 26. The topsoil within the Cell 3 portion of the project area will be separated from the suitable clay fill material. The topsoil will be transfer from the cell location to the stockpile area, by utilizing an excavator, GPS dozer and 40 ton articulating trucks. Hold Point – During the topsoil stripping process, any CCR waste identified for removal will be excavated and hauled to the active ILF Cells 1&2. 27. In order to create the subgrade design elevations and the clay liner, approximately 20,000 CY of soil will be utilized as cut-to-fill within Cell 3. This will be accomplished utilizing an excavator, 40 ton articulating dump trucks, GPS dozer, and Sheepsfoot roller Approximately 100,000 CY of Cell 3 soil will be excavated and hauled to the stockpile area. 28. Once the soil excavation has been completed, a roller will compact the clay liner while a GPS dozer fine grades to ensure the subgrade design elevations are achieved. Hold Point – Prior to installing the new liner system onto the subgrade of Cell 3, materials testing will be performed on the soils for density and moisture content as outlined in the Construction Quality Assurance Plan. Additionally, materials testing will be performed on the HDPE liner material to test for strength and resilience of the materials. All testing results will be reviewed with Duke Energy and Charah project teams. Direction on liner installation operations shall be provided prior to commencing. Hold Point – Prior to mobilizing any project material onsite approval shall be received from the EOR of the project. Additionally, when material is delivered, it will be inspected to ensure compliance and consistency with the submittal documents is maintained. 29. Once all material testing has been completed and approval received, the engineered liner system will be installed. Utilizing Chesapeake Containment Systems, the liner system for Cell 3 will be installed. The liner system consists of a geosynthetic clay liner (GCL), secondary 60-mil textured geomembrane, leak detection system (LDS) Marshall – ILF Cells 3 and 4 Landfill Construction 9 geocomposite drainage layer, primary 60-mil textured geomembrane, leachate collection system (LCS) geocomposite drainage layer, and a 2-foot protective cover. 30. The new Cell 3 liner system shall be tied into the existing liner system of the active Cell 1. The existing anchor trench of Cell 1 shall be potholed, to determined depths, and an excavator with a smooth-edge bucket shall be utilized to expose the liner edges. The two liner systems will be connected by utilizing extrusion welding techniques. 31. The protective cover layer will be bottom ash produced from the Marshall plant operations. Bottom ash will be hauled by on-road dump trucks and placed using a LGP dozer. These operations will continue until all of the liner within Cell 3 is covered with a 2-foot layer of bottom ash. 32. Once the liner system is installed, the LCS and LDS sump riser piping will be installed in the NW portion of the cell, as shown on the engineered plans. As the sump piping is installed, the cell’s LDS and LCS collection piping will be installed, along with the pipe bedding and filtration features, as shown on the LCS/LDS corridor details. 33. Once the LCS/LDS piping and filtration systems are installed, the chimney drains and infiltration zones will be installed in locations as detailed by the engineered plans. Cell 4 Construction 34. The topsoil within the Cell 4 portion of the project area will be separated from the suitable clay fill material. The topsoil will be transferred from the cell location to the stockpile area by an excavator, GPS dozer and 40-ton articulating trucks. Hold Point – During the topsoil stripping process, if CCR waste is identified for removal it will be excavated and hauled to the active ILF Cells 1&2. 35. Utilizing an excavator, 40-ton articulating dump trucks, GPS dozer, and Sheepsfoot roller, approximately 23,000 CY of soil will be utilized as cut-to-fill within Cell 4, in order to create the subgrade design elevations and the clay liner. 36. Approximately 53,500 CY of Cell 4 soil will be excavated, and hauled to the stockpile area, utilizing an approved haul route. 37. Once the soil excavation has been completed, a roller will be utilized to compact the clay liner, while a GPS dozer will fine grade to ensure the subgrade design elevations are achieved. Hold Point – Prior to installing the new liner system onto the subgrade of Cell 4, materials testing will be performed on the soils to test for density and moisture content in accordance with the Construction Quality Assurance Plan for the project. Additionally, materials testing will be performed on the HDPE liner material to test for strength and resilience of the materials. All testing results will be reviewed by Duke Energy and Charah project teams. Direction on liner installation operations will be provided prior to commencing. Marshall – ILF Cells 3 and 4 Landfill Construction 10 Hold Point – Prior to mobilizing any project material onsite approval shall be received from the EOR of the project. Additionally, when material is delivered, it will be inspected to ensure compliance and consistency with the submittal documents is maintained. 38. Once all material testing has been completed and approved, the engineered liner system will be installed. Utilizing Chesapeake Containment Systems, the liner system for Cell 4 will be installed. The liner system consists of a geosynthetic clay liner (GCL), secondary 60-mil textured geomembrane, leak detection system (LDS) geocomposite drainage layer, primary 60-mil textured geomembrane, leachate collection system (LCS) geocomposite drainage layer, and a 2-foot protective cover. 39. The new Cell 4 liner system shall be tied into the existing liner system of the active Cell 2. The existing anchor trench of Cell 2 shall be potholed, to determined depths, and an excavator with a smooth-edge bucket shall be utilized to expose the liner edges. The two liner systems will be connected by utilizing extrusion welding techniques. 40. The protective cover layer will be bottom ash produced from the Marshall plant operations. Bottom ash will be hauled by on-road dump trucks and placed using a LGP dozer. These operations will continue until all of the liner within Cell 3 is covered with a 2-foot layer of bottom ash. 41. Once the liner system is installed, the LCS and LDS sump riser piping will be installed in the NW portion of the cell, as shown on the engineered plans. As the sump piping is installed, the cell’s LDS and LCS collection piping will be installed, along with the pipe bedding and filtration features, as shown on the LCS/LDS corridor details. 42. 43. Once the LCS/LDS piping and filtration systems are installed, the chimney drains and infiltration zones will be installed in locations as detailed by the engineered plans. Erosion and Sediment Controls 44. Once all operations are completed, approximately 10 acres will be hydro-seeded to protect against erosion within the site. 45. All temporary erosion and sediment control measures will be left in place. Marshall – ILF Cells 3 and 4 Landfill Construction 11 3.0 Operational Experience Proper Emergency Communication Description:  Charah communicates closely with all employees to address changing conditions during operations. Recently, while performing E&S repairs on the Industrial Landfill at Marshall Steam Station, an operator was utilizing a skid steer to repair rilling on the side slopes when the subsurface of the side slope began to move. All work stopped and immediate alert was made to Charah management to begin investigating that area. Duke CCP management was notified and began conducting an engineering investigation of the area. Controls:  All project personnel will alert the Project Management, who will then immediately alert Duke Energy of any hazards encountered within the work area.  When operators encounter hazardous conditions they will stop operating the equipment and leave it in place and notify Duke Energy, who will then notify the Project Management to move equipment to a safe place or continue to work.  Charah Project Management will assess situation and provide guidance to operators to alleviate hazards.  No changes to Job Hazard Analysis or procedures are allowed unless approved in writing by Duke Energy.  Charah Project Management will work together to implement necessary changes and address emergency situations by following established communication protocol. . Mechanical Breakdown Communication Description:  Charah has had multiple incidents where mechanical breakdowns have occurred when heavy equipment was operational. Recently, while performing a stone overlay on a dike at Allen Steam Station, a wheel loader experience transmission issues. The operator communicated to the project manager of the issue. The machine was able to be transported to the designated laydown area, placed within the secondary containment, and called the rental company for mechanical support. These efforts were completed without impacting the safety of any personnel within the working area nor did these efforts impact the designated scope of work. Marshall – ILF Cells 3 and 4 Landfill Construction 12 Controls:  In the event of a mechanical failure operator shall make equipment safe and implement all measures necessary (spill kits, etc.) to contain a spill should it arise.  Operators will alert the Project Management immediately of any breakdowns, who will then notify Duke Energy.  Operators should not exit stalled equipment until traffic conditions are controlled.  Prompt contact with wrecking companies or mechanics is critical to quickly removing equipment and returning to service.  Duke Energy shall determine if the repairs will be on site or if the equipment should be moved.  In no case should equipment be moved if there is the potential for an oil, fuel, or hydraulic leak.  Any residue or sheen shall be reported to Duke Energy, who will then determine if a release has occurred. Operator Behavior Monitoring Description:  Charah Project Management responsibilities are to ensure that all equipment operators are “fit for duty”. Recently, at the Belews Creek landfill operations, a truck driver was suspected to have hearing difficulties. After further monitoring and communication with the truck driver, it was determined that the driver was in need of a hearing aid device. Charah assisted the employee with obtaining a hearing aid device and received medical clearance that the driver could return back to work. Controls:  Charah will perform a random route inspection daily to ensure all physical attributes of the equipment operators are fully functional  Charah will conduct morning briefs with each operator to ensure no one is operating equipment that is not “fit for duty”  Charah Project Management will monitor radio communication to ensure proper communication is being achieved Operating Near Obstructions Description: Marshall – ILF Cells 3 and 4 Landfill Construction 13  Everyday within the landfill operations, truck drivers come into close proximity of obstructions while entering and exiting loading areas. These areas are typically silos, gypsum pads, water truck filling stations, WWTS press stations and other stationary obstructions around power stations. Controls:  Designated spotters who are familiar with surroundings and equipment limitations/clearances will be utilized to direct equipment maneuvers. Operators will communicate with clear 3-part communication during all operations.  When directions are unclear or other potential hazards are encountered, operators will STOP and confirm conditions before proceeding Safe Dumping/Operating Practices Description:  Charah performed dumping operations within the Belews Creek Ash Basin to construct four access roads for monitoring wells. These operations consisted of loading, hauling and dumping approximately 9,000 CY of bottom ash within the basin and required close attention to safe dumping and operating techniques. Controls:  Trucks are not allowed to dump side by side.  Dumping is not allowed on slick or soft surfaces or a suspect surface that could result in a truck becoming stuck.  Any conditions or surfaces in question will not be operated on without written approval from Duke Management. If a suspect surface is encountered, stop work and follow Job Hazard Analysis procedure  Charah employees, the public and project team members’ safety is paramount and Charah will sacrifice productivity to maintain safety and well-being of all parties.

These observations are intended to be in addition to the procedures established as part of the Health and Safety Plan, Execution Plan and other established written plans. Effective communication (see Communication matrix for details) of safe and unsafe behaviors/conditions, environmental protection, is paramount to making this a successful Observation Plan. Behavior based safety is a process that provides a higher level of safety excellence by promoting proactive involvement, building ownership, and fostering communication that relates to employee safety. A primary concept is that most accidents are due to at‐risk behaviors and behavioral changes may be made that significantly reduce incident potential. Implementation: Charah’s dedicated team will make formal observations of site contractor personnel during performance of various field activities at the site. Team members are responsible for making site observations. The observer will utilize the Behavior Based Safety Checklist included as Attachment A of the Health and Safety Plan. Any unsafe acts or condition shall be corrected immediately and reported to the Duke Energy CCP Project Management. Incipient acts or conditions shall be noted and corrected but need not be reported at Duke Energy CCP Project Management’s discretion. Attachment D: Observations will include personnel actions/behavior, site conditions, environmental protection practices, and quality workmanship. Observations will be classified according to the list below: Positive Observations Unsafe Acts Unsafe Conditions Observations should be made at various work locations (Excavation and stockpile location, truck haul route locations, access road construction and employee break area). Any unsafe observation will result in immediate stop work and corrective action of unsafe act/condition. The observer will also provide coaching as needed and positive feedback when crews are observed working safely. Marshall – ILF Cells 3 and 4 Landfill Construction 23 To provide a successful observation plan, those responsible for observations cannot at any time condone unsafe behaviors. In the event of an incident and/or injury, the incident management plan and reporting procedures detailed in the Safety Plan will be followed. Observations and trending are critical components of a behavior based program. All team members are encouraged to provide observations throughout the project work. Definitions Unsafe Behavior: An individual’s actions that increase the chance of injury, despite knowledge of the hazard (i.e. excessive speed, improper PPE, etc.) Behaviors: Actions on the part of the individuals that can be characterized as safe or unsafe (i.e. smoking while operating, cell phone use, etc.). Corrective Action: Actions aimed at eliminating root cause(s) and preventing future similar events. To be effective corrective actions must satisfy three objectives: (DUKE HS‐007 Health and Safety Incident Reporting and Investigation): Prevent reoccurrence Be within the assigned organization’s control Meet business objectives (safety, reliability, economics and environment) Near Miss: A work related incident that could have, but did not cause injury or property damage if circumstances had been different (DUKE HS‐007 Health and Safety Incident Reporting and Investigation). Health and Safety Incident: An unplanned sequence of events with the potential for undesirable consequences. This includes: near miss, occupational injury/illness, industrial hygiene overexposure, fatality, vehicle or mobile equipment crash, fire, explosion, or any property damage because of the previously identified events (DUKE HS‐007 Health and Safety Incident Reporting and Investigation). Serious Injury/Fatality (SIF): Work related injury that results in one of these outcomes: Fatality Amputation (involving bone) Concussion and/or cerebral hemorrhages Injury to internal organs Bone fractures (including fingers and toes) Tendon and ligament tears Herniated disk (neck or back) Marshall – ILF Cells 3 and 4 Landfill Construction 24 Lacerations (resulting in severed tendons or a deep wound requiring internal stitches) 2nd degree burn (<10% body surface) or 3rd degree burns Eye injuries resulting in damage or loss of vision Injections of foreign materials (e.g. hydraulic fluid) Severe heat exhaustion and all heat stroke cases Dislocation of a major joint (hip, shoulder, elbow, etc.) Environmental Incident: An unplanned sequence of events with the potential for an adverse environmental effect: Chemical spill or leak Encountering an artesian water flow while excavating Discovering ash during an excavation Silt release into a body of water Observation Frequency Marshall Steam Station and Duke Energy CCP Safety team members may request or perform additional observations.

Contractor shall ensure conditions are proper for the use of those technologies. Prior to survey work commencing Surveyors shall provide training documentation/certifications on the surveying equipment to be used to ensure they are technically qualified to perform all task associated with survey scope. The following questions should be asked: Yes No ☐ ☐ Have drawings been reviewed for underground services and piping in the designated area for Trenching and Excavation? And has site operations been questioned to determine if additional utilities exist that are not on current drawings? ☐ ☐ Has a walk down of the designated area for Trenching and Excavation been performed to identify visual evidence of underground services or piping? Have Electro-Magnetic (EM) Technologies been utilized to; ☐ ☐ EM technology should be used to trace the route of metal pipe or power cables first. A signal generator should be used to trace the route of known conductive utilities. Marshall – ILF Cells 3 and 4 Landfill Construction 40 ☐ ☐ EM technology should also be used following two person parallel scanning patterns of 30 to 40 feet apart across the investigative area (smaller distance if area is smaller). See Figure 1. Four series of parallel scanning patterns should be performed (original direction, perpendicular to the original, 45 degrees from original and perpendicular to the 45 degree pattern). The two man scan should consist of one person using the signal transmitter/generator, and the second person using the receiver/detector. The end of each straight route of the scan shall be marked by some method (paint dot, flag, etc.) that can be verified by Duke Energy or designee. Have Ground Penetrating Radar (GPR) Technology been utilized to; ☐ ☐ Within 40 ft. of a building or structure that is served by underground utilities (water, sewage, electricity or data cable) Surveyor should perform a parallel scanning pattern using GPR technology no more than 4 feet apart. See Figure 2. The end of each straight route shall be marked by some method (paint dot, flag, etc.) that can be verified by Duke Energy or designee. Surveyor shall perform a parallel scanning pattern using GPR technology, no more than 4 feet apart, in a direction 90 degrees from the first pattern. The end of each straight route shall be marked by some method (paint dot, flag, etc.) that can be verified by Duke Energy or designee. ☐ ☐ Beyond 40 ft. of a building or structure. Surveyor shall perform a parallel scanning pattern using GPR technology no more than 10 feet apart. The end of each straight route shall be marked by some method (paint dot, flag, etc.) that can be verified by Duke Energy or designee. Surveyor shall perform a parallel scanning pattern using GPR technology no more than 10 feet apart, in a direction 90 degrees from the first set pattern. The end of each straight route shall be marked by some method (paint dot, flag, etc.) that can be verified by Duke Energy or designee ☐ ☐ Have all reasonable means been exhausted to determine if an underground service or piping could be present in the designated area for Trenching and Excavation? If any of the previous questions are answered as no:  Contact Station or Project Management (as applicable)  Consider performing a soft dig around the perimeter of and through the designated area for excavation and trenching to provide further inspection of underground services and piping.

Each Charah impoundment excavation project will be equipped with the following list of extraction equipment, well maintained, inspected on a regular basis, and dedicated to equipment extraction or OPS 2500-02 equipment towing and pulling only. (4) 6x37 Class IWRC 1 ½” x 20’ wire rope cable (4) 6x37 Class IWRC 1 ½” x 8’ wire rope cable (6) 35 Ton load rated screw pin anchor shackles (6) 25 Ton load rated screw pin anchor shackles (6) Recovery damper blankets (10) 4’x16’ (8”x8”) timber mats (2) 8’x8’ Steel road plates (10) Sheets 4’x8’ CDX plywood (6) Pair safety body harnesses and retractable lanyards The following operating requirements and guidelines highlight abnormal conditions requiring extraction of immobilized equipment. The first step in preventing heavy equipment from becoming immobilized within an impoundment, is by utilizing well trained Equipment Operators that understand the complexities of working on ash surfaces, including active or inactive. All Operators are required to complete the Charah Ash Basin Excavation Strategies and Safety Program. 2.0 Responsibilities Site Managers and Operators are responsible to maintain equipment and tools required to perform an extraction. Safety Specialists will verify this procedure is being followed to insure the safest possible outcome. 3.0 Definitions Immobilized equipment – equipment that is no longer capable of moving under its own power, due to mechanical failure or lodged in ash surface. 4.0 Recommended Equipment 4.1 Equipment Sizing Maximum operating weight of excavation equipment is conducive to specific impoundment conditions, with heavier weights acceptable as conditions permit. Best practices have proven machine operating weight under 100,000 lbs. is best suited for usual impoundment conditions. 5.0 Equipment Extractions 5.1 Response Charah responds to severe heavy equipment extraction with a specialized team of experienced internal personnel, including incident managers, qualified riggers, heavy equipment operators, and safety professionals. 5.2 Immobilized Equipment Marshall – ILF Cells 3 and 4 Landfill Construction 44 Due to the operating conditions at many sites, from time to time equipment may become stuck and/or mechanical failure causing it to be unable to be driven out under its own power. Excessive spinning of tracks or wheels can cause conditions to worsen or cause extensive damage to driveline components. When equipment becomes immobilized the operator shall stop and notify their supervisor for instruction. Charah standard operating procedure is to use appropriately sized cables, slings, and approved rigging. Appropriately sized machine(s) should be used to pull the equipment out of the stuck position. Place approved chocks or blocks on the recovery machine(s), as needed, to prevent it from moving forward/backward while attaching approved tow cables or approved rigging. Care should be taken to ensure the recovery machine(s) does not become stuck also. Only tow cables, slings, and approved rigging that are long enough to keep the recovery machine(s) on solid ground should be used. Cables, slings, and approved rigging should also be inspected and determined to be in good repair and of adequate load rating. 5.3 Towing Towing shall only be accomplished using the normally installed tow eyes and hooks on equipment. Under no circumstances will attachment be to bumpers, axles, or other non- approved locations. A trained operator shall be in each machine, and if conditions safely allow, one person off to the side to view and direct the operators actions. All personnel on the ground shall be a minimum distance equal to twice the length of the cable, approved rigging, or sling from the machines to prevent injury from a broken tow cable or sling. After retrieval of the lodged machine, it shall be thoroughly inspected for damage before being returned to service. Each site will locate and have available a qualified heavy wrecker/recovery service for on call as needed. As each project site is diverse and geographically separated it will be the responsibility of site management to determine the adequate service for their respective site. 6.0 Related Policies & Forms OPS-2500-00 Equipment Operations SAF-3300-00 Task Specific Compliance General SAF-5005-00 Management Compliance: Training Functional/Department Mgr Date VP of Operations Date President Date Marshall – ILF Cells 3 and 4 Landfill Construction 45 Attachment K – Equipment Towing Plan 1.0 Purpose To provide guidance in the towing and pulling of negligibly stranded or grounded heavy equipment.
