The proposed expansion will be built adjacent to (the west of) the existing landfill. The said portion of land is currently mostly wooded and an existing stream originates from this area as shown on Figure 1 (Vicinity Map). Using field survey, desktop review, and previously approved site study for this property, this report will show that the proposed expansion area will not impact public health and welfare and the environment. The author of this report is a qualified environmental professional and has sealed and signed this report. Civil & Environmental Consultants, Inc. -2- Anson Landfill Phase 5 Site Study November 2020 2.0 REGIONAL CHARACTERIZATION STUDY 15A NCAC 13B .1618C(1) The regional characterization study area includes the landfill facility and a two mile perimeter measured from the proposed boundary of the landfill facility. A regional map is presented as Exhibit 1 in Appendix A. 2.1 TOPOGRAPHY AND FEATURES (.1618(C)(1)(A)) The general vicinity and topography of Anson County Landfill (Landfill) is shown on Figure 2 (USGS Topography Map). The figure shows that the existing landfill is situated on a ridge that is bounded on the west by Brown Creek and on the east by Pinch Gut Creek. The CSX Railroad bounds the property to the immediate south and US Highway 74 further south. Features within two (2) miles of the property are shown on Exhibit 1 in Appendix A. Within this buffer, the surrounding area is rural and primarily wooded. The Town of Polkton is located within this buffer to the west. A portion of the Town of Wadesboro is also located within this buffer to the east. Residential, commercial, and industrial properties are scattered throughout the remaining 2-mile buffer area. The topographic features of the site and the immediate adjacent areas as shown in Figure 2 depict series of rolling hills that reach the heights of almost 350 feet above sea level. The lowest elevation is 250 feet above sea level before water drains to Brown Creek and Pinch Gut Creek. For a complete discussion of site topography and surface drainage, the reader is referred to the Design Hydrogeologic Investigation Report, prepared by Civil & Environmental Consultants, Inc. (dated March 2018). A copy of this report (excluding appendices) is presented in Appendix C. Civil & Environmental Consultants, Inc. -3- Anson Landfill Phase 5 Site Study November 2020 2.2 PROPOSED LANDFILL FACILITY LOCATION (.1618(C)(1)(B)) The Landfill is situated in the south-central portion of Anson County, North Carolina, north of US Highway 74. Entrance is at the southern end of the landfill on Dozer Drive, which is accessible from US Highway 74. The Landfill is currently comprised of four phases with a combined area of approximately 133 acres. The proposed expansion, Phase 5, will add approximately 66.90 acres over an area that is presently hilly and wooded southwest of the existing phases. The existing Landfill has been developed incrementally in phases. Within each phase, smaller cells were developed where the timing of construction were dictated by the owner and waste capacity. Phases 1 and 2 were permitted to construct in 2000 and 2008, respectively. Both are currently operational. Phases 3 and 4 were permitted to construct in 2018. Cell 2 of Phase 3, adjacent to Phase 4 (see Engineering Drawing C100 in Appendix B), is most recently constructed and is actively accepting waste. This site study is part of the permit to construct the proposed Phase 5 portion of the Landfill. Phasing and timing of Phase 5 construction will be established as has previously been upheld. Engineering drawings, provided in Appendix B, show the proposed design and progression of the landfill including the expansion area. The drawings depict floor grades, leachate conveyance, waste and final cover grades, erosion and sedimentation control measures, and stormwater management system. The projected life of Phase 5 is approximately 11.61 years based on the anticipated average incoming waste rate of 3,000 tons per day. 2.3 PUBLIC WATER SUPPLY WELLS, SURFACE WATER INTAKES, AND SERVICE AREAS (.1618(C)(1)(C)) Based on the Preliminary Siting Criteria map prepared by GZA Environmental in 1992 for the initial permitting and the GIS data from Anson County website*, public water supply wells, waterlines and fire hydrants are shown within two (2) miles of the property. They are Civil & Environmental Consultants, Inc. 4- Anson Landfill Phase 5 Site Study November 2020 represented as blue dots, black dashed lines, and red open circles, respectively, on Exhibit 1 in Appendix A. *(http://www.co.anson.nc.us/252/GIS-Data-Downloads) The nearest water supply wells are located within the Landfill property. Other water supply wells near the landfill are located outside of the landfill property lines, a minimum 1200 feet distance. 2A RESIDENTIAL SUBDIVISIONS (.1618(C)(1)(D)) Residential subdivisions are identified within 2 miles of the property but are scattered within the two mile buffer. Tighter clusters of residences are located within the Town of Polkton and Wadesboro closer to the outermost limit of the 2-mile buffer. 2.5 WASTE TRANSPORTATION ROUTES (.1618(C)(1)(E)) Waste materials are transported to the site using trucks and other suitable waste transport vehicles. Access to the site is directly from US Highway 74. The site access road is approximately 2,500 feet in length from the intersection of US Highway 74 to the scale area. This provides staging distance for waste transport vehicles arriving simultaneously. Waste loads contained in open top containers are inspected prior to reaching the scale area. If hazardous or other unacceptable waste is detected or observed, the load will be rejected and directed to leave the site without being allowed to deposit the waste material. Waste vehicles transporting acceptable waste will be weighed and allowed to pass the scales. The recycling building, tire processing area, yard waste composting area, and sanitary landfill are accessible from the main road, beyond the scale area. Vehicles will be directed to the appropriate waste processing area by site personnel and informational signs. After waste transport vehicles deposit their loads, they will exit the site using the main access road. All vehicles must pass by the scale area and be logged out. If necessary, vehicles can pass through a tire - Civil & Environmental Consultants, Inc. -5- Anson Landfill Phase 5 Site Study November 2020 wash area to remove mud or dirt prior to reaching US Highway 74. Any mud that reaches the public road will be promptly removed. 2.6 PUBLIC USE AIRPORTS AND RUNWAYS (.1618(C)(1)(F)) The nearest airport to the Anson County Landfill Solid Waste Management Facility is the Anson County Airport which is located approximately 4 miles northeast of the site. The proposed expansion will not affect public use of airport and runway as it is beyond the 10,000 foot setback requirements for turbine powered aircraft and 5,000 foot setback for the piston powered type aircraft. Civil & Environmental Consultants, Inc. -6- Anson Landfill Phase 5 Site Study November 2020 3.0 LOCAL CHARACTERIZATION STUDY 15A NCAC 13B .1618C(2) Local characterization study includes the landfill facility and a 2,000 feet perimeter from property boundary of the landfill facility. Exhibit 2 in Appendix A presents the 2,000-ft perimeter and an aerial photo as background. 3.1 DISPOSAL SITE (.1618(C)(2)(A)) The limit of waste within the property is shown on Exhibit 2 (Local Characterization Map). It shows the 2,000 foot perimeter as measured from the property boundary as well as the aerial photo which was taken from NCONE Map aerial imagery data, dated 2019. There are no on -site easements identified at the time of study. 3.2 EXISTING LAND USE AND ZONING (.1618(C)(2)(B)) Land use and zoning of the site and surrounding area of the Landfill have not been zoned in local zoning classification systems (Anson County GIS). The original permit included a letter from the Anson County Board of Commissioners stating this fact and is included in this report in Appendix J. However, since the original permit was approved in 2000, the site has been developed as a sanitary landfill. A portion of the site and areas located along US Highway 74 are zoned for light industry, commercial and residential purposes (Anson County GIS). Zoning areas, residences, commercial buildings, utilities, roads, wells, and water courses are shown on Exhibits 1 and 2. 3.3 LOCATION OF PRIVATE RESIDENCES AND SCHOOLS (.1618(C)(2)(C)) Private residences are located within 2,000 feet of the perimeter offset. They are represented as green dots on Exhibits 1 and 2. Local schools are not located within the 2,000 feet perimeter offset. They are represented as red diamonds on Exhibit 1. Civil & Environmental Consultants, Inc. -7- Anson Landfill Phase 5 Site Study November 2020 The expansion is designed to be, at minimum, 500 feet away from all residences and occupied buildings as required by Rule .1624 (b)(3)(B). 3A LOCATION OF COMMERCIAL AND INDUSTRIAL BUILDINGS (.1618(C)(2)(D)) There are no commercial or industrial buildings located within the 2,000 feet perimeter offset. Commercial buildings are shown, as pink dots, outside of this buffer on Exhibit 1. The expansion is designed to be, at minimum, 500 feet away from all residences and occupied buildings as required by Rule .1624 (b)(3)(B) which applies for this condition as well. 3.5 LOCATION OF POTABLE WELLS (.1618(C)(2)(E)) Locations of potable wells are shown on Exhibits 1 and 2 (blue dots). Historical locations were taken from a preliminary siting criteria map prepared by Riley, Park, Hayden & Associates, Inc. for Chambers Development of North Carolina, Inc. in January 1992. The map is presented in this report as a reference in Appendix J. 16 HISTORIC SITE (.1618(C)(2)(F)) A Cultural Resources report is presented in Appendix E. It describes the history of investigations at the site and provides an updated assessment of the sites in the proposed project area. 3.7 EXISTING TOPOGRAPHY FEATURES (.1618(C)(2)(G)) Existing topography of the Landfill is partially developed into the now operational Phases 1, 2, and 3. Surface water runoff from these developed areas are collected by temporary diversion ditches and perimeter channels that flow to existing basins before draining to surface water Civil & Environmental Consultants, Inc. -$- Anson Landfill Phase 5 Site Study November 2020 tributaries to Pinch Gut Creek. The portion of land where the proposed expansion development is currently wooded and drains to tributaries to Brown Creek. The 100-year floodplain is shown on Exhibit 1 and wetland areas as depicted in National Wetlands Inventory is shown on Figure 3. On August 2, 2016, Carolina Wetland Service (CWS) performed a site visit to delineate jurisdictional waters of the US. Wetlands and streams were identified in the project area. Of the jurisdictional streams, Stream A will be impacted by this project, consisting of approximately 1,466 linear feet and 0.08 acres of stream impact. This Stream A is shown on figures in the Jurisdictional Delineation Report in Appendix D. Streams B and C, and the wetlands identified in the CWS report will not be impacted by this project. Based on this proposed impact on Stream A, the Owner is currently preparing permitting documents for an Individual Permit with the United States Army Corps of Engineers (USACE), in accordance with Section 404 of the Clean Water Act. This Permit Application is submitted contingent on the Owner obtaining an Individual Permit for the stream impact area. 3.8 SITE HYDROGEOLOGIC REPORT (.1618(C)(3)) The site Hydrogeologic Report is presented in Appendix C and fulfills the requirements set forth in Rule .1623 (a). Civil & Environmental Consultants, Inc. -9- Anson Landfill Phase 5 Site Study November 2020 4.0 LOCATION RESTRICTIONS (.1618(C)(4)) 4.1 COMPLIANCE WITH RULE .1622 (2)(A) - FLOODPLAINS The proposed expansion is not located in the 100-year floodplain. The limit of waste versus the 100-year floodplain limit are shown on Exhibit 1 in Appendix A. Grading in the proposed expansion maintains positive drainage to stormwater treatment BMPs and then to existing tributaries. All waste materials will be contained within the Landfill by means of cell berms and proper waste compaction. 4.2 COMPLIANCE WITH RULE .1622 (3)(A)(III) - WETLANDS Carolina Wetland Services, Inc (CWS) provided a Jurisdictional Delineation Report on August 10, 2016. This report included the results of the on -site field investigations for jurisdictional waters located within the Anson County Landfill project limits. From this investigation CWS determined there were six jurisdictional waters of the U.S. located within the project limit. The determined waters of the U.S. located consist of three jurisdictional stream channels, two jurisdictional wetland areas, and one jurisdictional pond. The on -Site jurisdictional waters drain to Brown Creek and Pinch Gut Creek. Brown Creek and Pinch Gut Creek are part of the Yadkin Pee Dee River Basin (HUC 03040104) and are classified as "Class C Waters" by the NCDEQ. Class C waters are defined as: "Waters protected for uses such as secondary recreation, fishing, wildlife, fish consumption, aquatic life including propagation, survival and maintenance of biological integrity, and agriculture. Please see Jurisdictional wetlands study presented in Appendix D for full study. The Anson County Landfill permitted the placement of fill material in 1,177 linear feet of jurisdictional stream and 0.125 acre of jurisdictional wetlands to provide solid waste disposal services to Anson County customers. Approval from the U.S. Army Corp was received in a letter dated May 13, 2020 giving Waste Connections permission to place fill material in the above mentioned proposed impacted areas. The Landfill also received 401 Water Quality Certification approval from NCDEQ April 28, 2020 for the same impacts as listed above. Please see Jurisdictional wetlands study presented in Appendix D for full study. Please see U.S. Army Corp Civil & Environmental Consultants, Inc. -10- Anson Landfill Phase 5 Site Study November 2020 Approval and 401 Water Quality Certification approval letters presented in Appendix D for full approval conditions. 4.3 COMPLIANCE WITH RULE .1622 (4)(A) — FAULT AREAS Per Regulation Rule .1622(4)(a): "MSWLF units shall not be located within 200 feet (60 meters) of a fault that has had displacement in Holocene time unless the owner or operator demonstrates to the Division that an alternative setback distance of less than 200 feet (60 meters) will prevent damage to the structural integrity of the MSWLF unit and will be protective of human health and the environment." That region in which the Anson County Landfill is located is not known to be seismically active. A review of the Preliminary Map of Young Faults in the United States As a Guide to Possible Fault Activity (Howard, et al, 1978) suggests the age of the youngest known displacement on the only regional fault noted occurred more than 15 million years ago. In addition, this fault is located a significant distance from the Anson County Landfill. 4.4 COMPLIANCE WITH RULE .1622 (5)(A) — SEISMIC IMPACT ZONES The Anson County Landfill is located in a seismic impact zone as defined in Subpart B of the EPA's MSW Landfill Criteria Technical Manual: "...an area with a ten percent or greater probability that the maximum horizontal acceleration in lithified earth material, expressed as a percentage of earth's gravitational pull (g), will exceed 0.10g in 250 years." The structural components including liners, leachate collection and removal systems, surface water control systems will be designed to resist the maximum horizontal acceleration. The seismic design for landfill components will be presented in the Permit to Construct Application. 4.5 COMPLIANCE WITH RULE .1622 (6)(A) — UNSTABLE AREAS Geotechnical investigations at the Anson County Landfill have demonstrated that site soils are stable. In addition, cell design drawings typically specific that soils are stripped to, or close to, the underlying bedrock, after which structural fill is placed to construct the base grades of new Civil & Environmental Consultants, Inc. -11- Anson Landfill Phase 5 Site Study November 2020 cells. As such, landfill foundations are sound. Further, the area in which the Anson County Landfill is located is not susceptible to mass movement, and is not underlain by karst terrain. 4.6 COMPLIANCE WITH RULE .1622 (8) — STATE NATURE AND HISTORIC PRESERVE Brockingham and Associates, Inc. completed a background literature review of the Anson County Regional Landfill tract located in Anson County, in October 2020. Brockingham and Associates, Inc requested background documents and site records from the Research Center Collections Manager at the Office of State Archaeology (OAR) in Raleigh, NC to identify all previously documented cultural resources and to assess the potential for any historic properties to be impacted by the current expansion and future land use of the landfill. All work was in compliance with Section 106 of the National Historic Preservation Act as administered through regulatory programs of the NC State Historic Preservation Office (SHPO) and USACE. From this review, Brockingham and Associates, Inc found that the Anson County Landfill will not have an adverse impact on any lands included in the State Nature and Historic Preserve. Please see Cultural Resources Literature Review report in Appendix Appendix J for full review. 4.7 COMPLIANCE WITH RULE .1622 (9) — WATER SUPPLY WATERSHEDS The Anson County Landfill will not be located within in the critical area of a water supply watershed or in the watershed for a stream segment classified as WS-I, in accordance with the rules codified at 15A NCAC 2B .0200 - "Classifications and Water Quality Standards Applicable To Surface Waters Of North Carolina." Brown Creek and Pinch Gut Creek are part of the Yadkin Pee Dee River Basin (HUC 03040104) and are classified as "Class C Waters" by the NCDEQ. Class C waters are defined as: "Waters protected for uses such as secondary recreation, fishing, wildlife, fish consumption, aquatic life including propagation, survival and maintenance of biological integrity, and agriculture. The Anson County Landfill with obtain a National Pollution Discharge Elimination System (NPDES) Permit from the Division of Environmental Management pursuant to Section 402 of the United States Clean Water Act prior to discharging Civil & Environmental Consultants, Inc. -12- Anson Landfill Phase 5 Site Study November 2020 II or WS-III, in accordance with the rules codified at 15A NCAC 2B .0200 - "Classifications and Water Quality Standards Applicable To Surface Waters Of North Carolina." 4.8 COMPLIANCE WITH RULE .1622 (10) — ENDANGERED AND THREATENED SPECIES A Protected Species Assessment was conducted by Carolina Wetland Services (CWS) in August 2016. CWS used North Carolina Natural Heritage Program (NCNHP) to determine if any record occurrences of federally -listed, candidate endangered, threatened species, or critical habitat are located within the project area. Based on this review, there are no current records of federally - protected species within the project limits or within a mile of the project site. CWS also conducted an on -site assessment for federally -protected endangered, threatened, and candidate species, it was determined that there was no suitable habitat for Schweinitz's sunflower, red - cockaded woodpecker, and shortnose sturgeon within the project limits. According to the literature search and on -site assessment performed by CWS the Anson Landfill does not jeopardize the continued existence of endangered or threatened species or result in the destruction or adverse modification of a critical habitat, protected under the Federal Endangered Species Act of 1973. See Protected Species Assessment Report presented in Appendix F for full study. Civil & Environmental Consultants, Inc. -13- Anson Landfill Phase 5 Site Study November 2020 5.0 GOVERNMENT APPROVALS Per the requirement of 15 NCAC 13B .1618 (5), a Franchise Agreement is presented in Appendix G which shows the agreement between Chambers Development of North Carolina with Anson County and provides information regarding public hearings held prior to obtaining said agreement. Civil & Environmental Consultants, Inc. -14- Anson Landfill Phase 5 Site Study November 2020 6.0 PROPOSED FACILITY PLAN 6.1 PURPOSE AND SCOPE 6.1.1 Introduction and Facility Information Anson County Landfill (Landfill) is located in Anson County between Polkton and Wadesboro on US Highway 74. The site is bordered to the northwest by Brown Creek, the east by Pinch Gut Creek, and the south by the CSX railroad. The facility location is presented on Figure 1 Vicinity Map. The Landfill currently operates under Solid Waste Facility Permit Number 0403. 6.2 WASTE STREAM -15A NCAC RULE. 1626 (1) & (9) 6.2.1 Types of Wastes The Landfill will not accept types of waste prohibited by 15A NCAC 13B, which include: • Hazardous wastes as defined within 15A NCAC 13A to include hazardous wastes from conditionally exempt small quantity generators; • Polychlorinated biphenyls (PCBs) wastes as defined in 40 CFR 761; • Liquid wastes except as provided by 15A NCAC 13B .1626(9); • Untreated regulated medical wastes; and • Petroleum contaminated soils. The following waste types will not be accepted for landfilling, but may be accepted at a drop-off for alternative processing: • White goods; • Used oil; • Lead -acid batteries; • Petroleum contaminated waste; Civil & Environmental Consultants, Inc. -15- Anson Landfill Phase 5 Site Study November 2020 • Whole scrap tires; • ABC Container Recycling; • Electronics; • Fluorescent Lights; • Mercury Containing Thermostats; • Oil Filters; • Plastic Bottles; • Wood Pallets; and • Yard waste. The Landfill will accept all types of municipal solid waste (MSW) and special wastes, to include: • Spoiled foods, animal carcasses, abattoir waste, hatchery and other animal wastes; • Asbestos waste; • Treated medical wastes which are not hazardous, liquid, infectious or radioactive; • Wastewater treatment sludges; • Construction/ demolition wastes; • Ash (non -medical); Coal ash may be accepted for disposal after approval of Anson County and the Solid Waste Section; • Industrial process waste; • Off -specification, outdated commercial products; • Barrels and drums which are empty and have been perforated sufficiently to ensure that no liquid or hazardous waste is contained therein, except for fiber drums containing asbestos; • Laboratory waste (non -hazardous); and • Other non-MSW wastes not excluded above. Acceptance of special wastes will be subject to provisions of 15A NCAC 13B, the special waste acceptance procedures defined in the Operations Plan included in this application. Civil & Environmental Consultants, Inc. -16- Anson Landfill Phase 5 Site Study November 2020 The landfill operator shall be responsible for screening wastes to ensure that hazardous or unacceptable wastes are not disposed in the landfill. Screening of special wastes shall be performed in accordance with the Operations Plan. Landfill management reserves the right to establish acceptance criteria and procedures for certain non -municipal solid wastes. These may be more restrictive than required by law based on quantities and characteristics of the waste stream, current operating status of the Landfill, and characteristics of waste streams previously received. Acceptability will be based on judgment of the landfill operator's technical personnel with respect to regulatory requirements, physical and chemical qualities and other technical considerations. 6.2.2 Disposal Rates A March, 2018 Franchise Agreement limited waste acceptance of 6,000 tons per day. The facility will accept only those items listed in 15A NCAC RULE .1626 (1) & (9) that have not come in contact with hazardous constituents, petroleum products, or lead based paints or waste determined as acceptable by the Department based on the submittal of a waste characterization report and will screen the incoming waste in accordance with 1 SA NCAC RULE .1626 (1) & (9). 6.2.3 Service Area In accordance with the agreement between Anson County and WCN, the Landfill will serve Anson County and other parts of North Carolina and South Carolina. 6.2.4 Waste Segregation Incoming waste will be observed to verify it is acceptable in content and origin. Accurate and current records will be maintained for all accepted waste and all Landfill operations. Waste handling procedures and normal operating procedures will be implemented to prevent disposal of unauthorized waste. Civil & Environmental Consultants, Inc. -17- Anson Landfill Phase 5 Site Study November 2020 6.2.4.1 Types of Waste The Landfill will only accept solid waste as described in 1 SA NCAC 13B and will not accept wastes as described in Section 2.2.1. The Landfill may accept special wastes and handling procedures will be implemented by waste type. The special wastes that may be accepted include: o Bulky Waste- Bulky waste such as furniture, appliances, and other over -sized items will be handled such that compaction is maximized and management at the working face is prompt. Bulky wastes will typically be crushed on the ground prior to disposal. If crushing or other size reduction is not possible, bulky wastes will be placed at the base of the working face and run over with the landfill compactor to reduce their size. The bulky waste will then be placed at the toe of the working face and covered with other waste. o Low -Density Wastes- Waste types such as agricultural wastes, loose plastic film, foam rubber, plastic scraps, and plastic shavings require special handling. These materials present problems because they rebound after being compacted by the equipment. In order to achieve maximum densities, light -weight materials should be spread into layers between one (1) and two (2) feet deep before being covered with regular waste and compacted as usual into the base of the cell. o Powdery Waste- The Landfill may accept powdery waste such as ash, sawdust or exhaust trappings. Since these wastes are dry and powdery, they require special management to minimize dusting and blowing. The principal means of controlling these wastes will be wetting or quickly covering with other waste. If conditions warrant, landfill workers managing these wastes will wear protective clothing and respirators as determined by the site safety officer. o Sludges -The Landfill will accept neither municipal sewer sludge nor sludges containing free liquids, as determined by the Paint Filter Liquids test. The Landfill will accept all other sludges subject to the requirement of the Operations Plan's Special Waste Quality Assurance Plan. Sludges that are determined to be acceptable will be mixed/ bulked with municipal solid waste or other solid waste at the working face. Sludges will be stabilized, digested, or heat treated prior to disposal. Civil & Environmental Consultants, Inc. -18- Anson Landfill Phase 5 Site Study November 2020 The amount of sludge managed on a daily basis will be dictated by operating conditions. A maximum ratio of one (1) ton of sludge to five (5) tons of solid waste for daily intake of sludges will be employed. o Free Liquids- The Landfill will not accept solid wastes that contain free liquids as determined by the Paint Filter Liquids Test. However, liquid waste may be treated by solidification, or thickening, to make the waste suitable for landfill disposal. Solidification of liquid waste will be conducted in leak -resistant containers or steel tanks partially buried within an active landfill cell. Incoming liquid waste will be deposited directly into the containers with a solidification agent. Solidification may be accomplished using soil, mulch, wood chips, etc. The liquid waste will be mixed with the solidifying agent in the tanks using a backhoe or other appropriate equipment until free liquid is no longer observed. The solidified waste will then be removed from the tanks and disposed at the working face. The number and location of mixing tanks will be dictated by the Landfill operations. The requirements of this section do not apply to leachate recirculation or landfill gas condensate management. o Putrescible Waste- Animal carcasses, in small volumes, may be managed at the Landfill. If a large volume is delivered to the Landfill, they will be accepted in a designated area away from the working face and promptly covered. o Asbestos Containing Material- The Landfill will contain areas designated for the management of asbestos waste. The management of asbestos waste will follow the procedures described in Appendix D and Appendix E of the Operations Plan. o Tires- The Landfill will not accept whole tires for disposal. Tires pulled from waste loads delivered to the landfill will be temporarily stockpiled in piles not exceeding five (5) feet high, or in trailers. Proper management of collected tires will be arranged as needed. Civil & Environmental Consultants, Inc. -19- Anson Landfill Phase 5 Site Study November 2020 6.2.4.2 Weighing and Control of Waste Volumes All landfill users entering the disposal area must stop on the scales at the entrance gate for security check -in. The load weight, customer, and charges will be recorded for all trucks delivering waste to the disposal area. The Landfill will promptly repair any malfunctioning scales. Vehicles will be directed to the appropriate disposal area by signs. However, verbal or other instructions may be given if necessary. All open topped waste loads will be inspected for hazardous or otherwise unacceptable wastes by the gatekeeper from the observation platform above the gate house. All other waste loads will be inspected at the active face by the equipment operators 6.2.4.3 Inspection A plan will be implemented by the Site Manager to prevent the onsite disposal of unauthorized hazardous wastes. The plan will contain an inspection program to be staffed by personnel who have been trained to recognize unauthorized hazardous wastes. At a minimum, the following shall be included in the inspection program: • Periodic vehicle inspection of loads at the gate and at the landfill face that document all suspicious materials, the hauler, and if possible, the generator; • Random monitoring of organic vapors from open top loads using suitable instruments; • Thorough inspection of suspicious loads; • Training of personnel to recognize regulated hazardous wastes; and • Establishment of specific procedures for notification of proper authorities if a regulated hazardous waste is discovered. Civil & Environmental Consultants, Inc. -20- Anson Landfill Phase 5 Site Study November 2020 6.2.4.4 Equipment and Staffing The Landfill will provide the appropriate level of equipment and staff to address the needs of a landfill that accepts a maximum of 6,000 tons per day. If waste acceptance changes, the equipment and staff levels will change accordingly. All employees associated with the waste management operations will be properly trained for their respective duties. Additional geotechnical testing and analysis throughout construction and operations will confirm the quantities and types of materials required as construction commences and operations continue. 6.3 CONTAINMENT AND ENVIRONMENTAL CONTROLS - 15A NCAC RULE .1619(E) (3) 6.3.1 Leachate Migration Leachate migration will be controlled by a base liner system, leachate collection system (LCS), and final cover system. Daily and intermediate cover may be removed to the extent possible prior to placing additional refuse vertically during operation of the landfill to promote percolation downward to the LCS. Downward migration of leachate into natural ground will be prevented by the base liner system and LCS. The base liner system complies with the requirements of I5A NCAC Rule .1624(b) (1) (A), comprising of a composite liner system and an LCS. 6.3.2 Landfill Gas Management A LFG management system minimizes gas pressure exerted on the closure cap system, eliminates uncontrolled emissions, reduces the potential for odor conditions to develop, and reduces the potential for subsurface migration of landfill gas. The Landfill's LFG management is based on a Landfill Gas Master Plan prepared by SCS Engineers dated November 20, 2007 and revised by Civil & Environmental Consultants, Inc. for this Permit Application. The Landfill Civil & Environmental Consultants, Inc. -21- Anson Landfill Phase 5 Site Study November 2020 Gas Master Plan has been updated for the entire Landfill facility, Phases 1 through 5. LFG management will use an active gas extraction and collection system with auxiliary gas management features. The LFG will be collected using vertical extraction wells installed in the waste which will be connected to collection piping under a constant vacuum generated by a dedicated blower system. Collected LFG will be combusted in the onsite landfill gas flare(s), which will consume the hydrocarbons present in the LFG, reducing hydrocarbon emissions and global warming potential. Vertical extraction well installation will begin once the closure cap is constructed. However, wells may be installed prior to final grades, if the operator determines they will provide effective gas collection capability. Gas migration monitoring is required at the perimeter of the Landfill property line and must be performed in accordance with the requirements of 15A NCAC 13B .1626. 6.3.3 Soil Resources Cut and fill soil volumes were calculated for construction, operations, and closure for Phase 5. The cut and fill soil volumes include construction of base grades, compacted soil liner, protective cover, daily and intermediate cover, perimeter roads, and closure final cover. Approximately 5,415,641 cubic yards of soil fill material will be needed to complete the construction, operations, and closure of the Landfill. An existing onsite soil borrow area and other areas that could be used as borrow areas are available for production of the required soils. Chambers Development of North Carolina, Inc. has recently purchased an adjoining parcel of approximately 300 acres that could be utilized for soil resources in the future. Alternatively, alternate daily cover approved by DEQ may be used to reduce the amount of daily intermediate cover required. Civil & Environmental Consultants, Inc. -22- Anson Landfill Phase 5 Site Study November 2020 7.0 TRAFFIC STUDY The Anson County Landfill is not proposing or anticipating any increase in daily tonnage coming to the site, therefore no traffic increase is anticipated. This site study is for an expansion to increase the total capacity for the landfill and daily volumes will not change. CEC coordinated with NCDOT with the above information and per the attached electronic correspondence letter from the Division Engineer of the North Carolina Department of Transportation located in Appendix H, NCDOT will not be requiring a new driveway permit or any roadway improvements from the expansion. With this documentation the landfill meets the requirements in accordance to NCGS 130A-295.5 (a) and (b).

PURPOSE: TO REDUCE EROSION AND DECREASE SEDIMENT YIELD FROM DISTURBED AREAS, AND TO PERMANENTLY STABILIZE SUCH AREAS IN A MANNER THAT IS ECONOMICAL, ADAPTS TO SITE CONDITIONS, AND ALLOWS SELECTION OF THE MOST APPROPRIATE PLANT MATERIALS. G E a 0 N C N a ■:3 SEEDBED REQUIREMENTS: ESTABLISHMENT OF VEGETATION SHOULD NOT BE ATTEMPTED ON SITES THAT ARE UNSUITABLE DUE TO INAPPROPRIATE SOIL TEXTURE (NC EROSION AND SEDIMENT CONTROL PLANNING AND DESIGN MANUAL, 1988), POOR DRAINAGE, CONCENTRATED OVERLAND FLOW, OR STEEPNESS OF SLOPE UNTIL MEASURES HAVE BEEN TAKEN TO CORRECT THESE PROBLEMS. TO MAINTAIN A GOOD STAND OF VEGETATION, THE SOIL MUST MEET CERTAIN MINIMUM REQUIREMENTS AS A GROWTH MEDIUM. THE EXISTING SOIL SHOULD HAVE THESE CRITERIA: — ENOUGH FINE—GRAINED (SILT AND CLAY) MATERIAL TO MAINTAIN ADEQUATE MOISTURE AND NUTRIENT SUPPLY (AVAILABLE WATER CAPACITY OF AT LEAST .05 INCHES WATER TO 1 INCH OF SOIL). — SUFFICIENT PORE SPACE TO PERMIT ROOT PENETRATION. — SUFFICIENT DEPTH OF SOIL TO PROVIDE AN ADEQUATE ROOT ZONE. THE DEPTH TO ROCK OR IMPERMEABLE LAYERS SUCH AS HARDPANS SHOULD BE 12 INCHES OR MORE, EXCEPT ON SLOPES STEEPER THAN 2:1 WHERE THE ADDITION OF SOIL IS NOT FEASIBLE. — A FAVORABLE PH RANGE FOR PLANT GROWTH, USUALLY 6.0 — 6.5. — FREE FROM LARGE ROOTS, BRANCHES, STONES, LARGE CLODS OF EARTH, OR TRASH OF ANY KIND. CLODS AND STONES MAY BE LEFT ON SLOPES STEEPER THAN 3:1 IF THEY ARE TO BE HYDROSEEDED. IF ANY OF THE ABOVE CRITERIA ARE NOT MET — I.E., IF EXISTING SOIL IS TOO COARSE, DENSE, SHALLOW OR ACIDIC TO FOSTER VEGETATION — SPECIAL AMENDMENTS ARE REQUIRED. THE SOIL CONDITIONERS DESCRIBED BELOW MAY BE BENEFICIAL OR, PREFERABLY, TOPSOIL MAY BE APPLIED. SEEDBED PREPARATION INSTALL NECESSARY MECHANICAL EROSION AND SEDIMENTATION CONTROL PRACTICES BEFORE SEEDING, AND COMPLETE GRADING ACCORDING TO THE APPROVED PLAN. LIME AND FERTILIZER NEEDS SHOULD BE DETERMINED BY SOIL TESTS. SOIL TESTING IS PERFORMED FREE OF CHARGE BY THE NORTH CAROLINA DEPARTMENT OF AGRICULTURE SOIL TESTING LABORATORY. DIRECTIONS, SAMPLE CARTONS, AND INFORMATION SHEETS ARE AVAILABLE THROUGH COUNTY AGRICULTURAL EXTENSION OFFICES OR FROM NCDA. BECAUSE THE NCDA SOIL TESTING LAB REQUIRES 1-6 WEEKS FOR SAMPLE TURN —AROUND, SAMPLING MUST BE PLANNED WELL IN ADVANCE OF FINAL GRADING. TESTING IS ALSO DONE BY COMMERCIAL LABORATORIES. WHEN SOIL TESTS ARE NOT AVAILABLE, FOLLOW RATES SUGGESTED IN THE SEEDING SPECIFICATIONS SHOWN AT RIGHT. APPLICATION RATES USUALLY FALL INTO THE FOLLOWING RANGES: GROUND AGRICULTURAL LIMESTONE: — LIGHT —TEXTURED, SANDY SOILS: 1 TO 1-1/2 TONS/ACRE — HEAVY —TEXTURED, CLAYEY SOILS: 2-3 TONS/ACRE FERTILIZER: — GRASSES: 800-1200 LB/ACRE OF 10-10-10 (OR THE EQUIVALENT) — GRASS —LEGUME MIXTURES: 800-1200 LB/ACRE OF 5-10-10 (OR THE EQUIVALENT) APPLY LIME AND FERTILIZER EVENLY AND INCORPORATE INTO THE TOP 4-6 INCHES OF SOIL BY DISKING OR OTHER SUITABLE MEANS. OPERATE MACHINERY ON THE CONTOUR. WHEN USING A HYDROSEEDER, APPLY LIME AND FERTILIZER TO A ROUGH, LOOSE SURFACE. ROUGHEN SURFACES PRIOR TO SEEDING. COMPLETE SEEDBED PREPARATION BY BREAKING UP LARGE CLODS AND RAKING INTO A SMOOTH, UNIFORM SURFACE (SLOPES LESS THAN 3:1). FILL IN OR LEVEL DEPRESSIONS THAT CAN COLLECT WATER. BROADCAST SEED INTO A FRESHLY LOOSENED SEEDBED THAT HAS NOT BEEN SEALED BY RAINFALL. TEMPORARY SEEDING SPECIFICATIONS AREAS LEFT DISTURBED FOR LONGER THAT 30 DAYS BUT LESS THAN ONE (1) YEAR: Time Period Item Rate of Application (lb./acre) January Ito May 1 Rye (Grain) 120 Annual Lespedeza (Kobe) 50 Limestone 2,000 10-10-10 Fertilizer 750 Nitrogen (March only) 50 Mulch 4,000 May 1 to August 15 German Millet 40 Limestone 2,000 10-10-10 Fertilizer 750 Mulch 4,000 August 15 to December 30 Rye (Grain) 120 Limestone 2,000 10-10-10 Fertilizer 750 Mulch 4,000 If it is necessary to extend temporary cover beyond June 15, the area should be overseeded with 50 lb/acre of Kobe lespedeza in latter February or early March. SOIL AMENDMENTS FOLLOW RECOMMENDATIONS OF SOIL TESTS OR APPLY 2,000 LB/ACRE GROUND AGRICULTURAL LIMESTONE AND 750 LB/ACRE 10-10-10 FERTILIZER. MULCH APPLY 4,000 LB/ACRE STRAW. ANCHOR MULCH BY TACKING WITH ASPHALT, ROVING OR A MULCH ANCHORING TOOL. A DISK WITH BLADES SET NEARLY STRAIGHT CAN BE USED AS A MULCH ANCHORING. TOOL. MAINTENANCE REFERTILIZE IF GROWTH IS NOT FULLY ADEQUATE. RESEED, REFERTILIZE AND MULCH IMMEDIATELY FOLLOWING EROSION OR OTHER DAMAGE. SEEDING SEEDING DATES GIVEN IN THE SEEDING MIXTURE SPECIFICATIONS ARE DESIGNATED AS "BEST" OR "POSSIBLE". SEEDINGS PROPERLY CARRIED OUT WITHIN THE "BEST" DATES HAVE A HIGH PROBABILITY OF SUCCESS. IT IS ALSO POSSIBLE TO HAVE SATISFACTORY ESTABLISHMENT WHEN SEEDING OUTSIDE THESE DATES. HOWEVER, AS YOU DEVIATE FROM THEM, THE PROBABILITY OF FAILURE INCREASES RAPIDLY. SEEDING ON THE LAST DATE SHOWN UNDER "POSSIBLE" MAY REDUCE CHANGES OF SUCCESS BY 30-50%. ALWAYS TAKE THIS INTO ACCOUNT IN SCHEDULING LAND —DISTURBING ACTIVITIES. USE CERTIFIED SEED FOR PERMANENT SEEDING WHENEVER POSSIBLE. CERTIFIED SEED IS INSPECTED BY THE NORTH CAROLINA CROP IMPROVEMENT ASSOCIATION. IT MEETS PUBLISHED NORTH CAROLINA STANDARDS AND SHOULD BEAR AN OFFICIAL "CERTIFIED SEED" LABEL. LABELING OF NON —CERTIFIED SEED IS ALSO REQUIRED BY LAW. LABELS CONTAIN IMPORTANT INFORMATION ON SEED PURITY, GERMINATION, AND PRESENCE OF WOOD SEEDS. SEEDS MUST MEET STATE STANDARDS FOR CONTENT OF NOXIOUS WEEDS. DO NO ACCEPT SEED CONTAINING "PROHIBITED" NOXIOUS WEED SEED. INOCULATE LEGUME SEED WITH THE RHIZOBIUM BACTERIA APPROPRIATE TO THE SPECIES OF LEGUME. APPLY SEED UNIFORMLY WITH A CYCLONE SEEDER, DROP —TYPE SPREADER, DRILL, CULTIPACKER SEEDER, OR HYDROSEEDER ON A FIRM, FRIABLE SEEDBED. WHEN USING A DRILL OR CULTIPACKER SEEDER, PLANT SMALL GRAINS NO MORE THAN 1 INCH DEEP, GRASSES AND LEGUMES NO MORE THAN 1 /2 INCH. EQUIPMENT SHOULD BE CALIBRATED IN THE FIELD FOR THE DESIRED SEEDING RATE. WHEN USING BROADCAST —SEEDING METHODS, SUBDIVIDE THE AREA INTO WORKABLE SECTIONS AND DETERMINE THE AMOUNT OF SEED NEEDED FOR EACH SECTION. APPLY ONE—HALF THE SEED WHILE MOVING BACK AND FORTH ACROSS THE AREA, MAKING A UNIFORM PATTERN: THEN APPLY THE SECOND HALF IN THE SAME WAY, BUT MOVING AT RIGHT ANGLES TO THE FIRST PASS. MULCH ALL PLANTINGS IMMEDIATELY AFTER SEEDING. HYDROSEEDING: SURFACE ROUGHENING IS PARTICULARLY IMPORTANT WHEN HYDROSEEDING, AS A ROUGHENED SLOPE WILL PROVIDE SOME NATURAL COVERAGE FOR LIME, FERTILIZER, AND SEED. THE SURFACE SHOULD NOT BE COMPACTED OR SMOOTH. FINE SEEDBED PREPARATION IS NOT NECESSARY FOR HYDROSEEDING OPERATIONS: LARGE CLODS, STONES, AND IRREGULARITIES PROVIDE CAVITIES IN WHICH SEEDS CAN LODGE. RATE OF WOOD FIBER (CELLULOSE) APPLICATION SHOULD BE AT LEAST 2,000 LB/ACRE. APPLY LEGUME INOCULATES AT FOUR TIME THE RECOMMENDED RATE WHEN ADDING INOCULATE TO A HYDROSEEDER SLURRY. IF A MACHINERY BREAKDOWN OF 1 /2 TO 2 HOURS OCCURS, ADD 50% MORE SEED TO THE TANK, BASED ON THE PROPORTION OF THE SLURRY REMAINING. THIS SHOULD COMPENSATE FOR DAMAGE TO SEED. BEYOND 2 HOURS, A FULL RATE OF NEW SEED MAY BE NECESSARY. LIME IS NOT NORMALLY APPLIED WITH A HYDRAULIC SEEDER BECAUSE IT IS ABRASIVE. IT CAN BE BLOWN ONTO STEEP SLOPES IN DRY FORM. MAINTENANCE: GENERALLY, A STAND OF VEGETATION CANNOT BE DETERMINED TO BE FULLY ESTABLISHED UNTIL SOIL COVER HAS BEEN MAINTAINED FOR ONE FULL YEAR FROM PLANTING, INSPECT SEEDED AREAS FOR FAILURE AND MAKE NECESSARY REPAIRS AND RESEEDINGS WITHIN THE SAME SEASON, IF POSSIBLE. RESEEDING: IF A STAND HAS INADEQUATE COVER, RE—EVALUATE CHOICE OF PLANT MATERIALS AND QUANTITIES OF LIME AND FERTILIZER. RE—ESTABLISH THE STAND AFTER SEEDBED PREPARATION OR OVER— SEED THE STAND. CONSIDER SEEDING TEMPORARY, ANNUAL SPECIES IF THE TIME OF YEAR IS NOT APPROPRIATE FOR PERMANENT SEEDING. IF VEGETATION FAILS TO GROW, SOIL MUST BE TESTED TO DETERMINE IF ACIDITY OR NUTRIENT IMBALANCE IS RESPONSIBLE. FERTILIZATION: ON THE TYPICAL DISTURBED SITE, FULL ESTABLISHMENT USUALLY REQUIRES REFERTILIZATION IN THE SECOND GROWING SEASON. FINE TURF REQUIRES ANNUAL MAINTENANCE FERTILIZATION. USE SOIL TESTS IF POSSIBLE OR FOLLOW THE GUIDELINES GIVEN FOR THE SPECIFIC SEEDING MIXTURE.

CLEAR, GRUB, AND STRIP THE AREA UNDER THE EMBANKMENT OF ALL VEGETATION AND ROOT MAT. REMOVE ALL SURFACE SOIL CONTAINING HIGH AMOUNTS OF ORGANIC MATTER AND STOCKPILE OR DISPOSE OF IT PROPERLY. HAUL ALL OBJECTIONABLE MATERIAL TO THE DESIGNATED DISPOSAL AREA. PLACE TEMPORARY SEDIMENT CONTROL MEASURES BELOW BASIN AS NEEDED. 2. ENSURE THAT FILL MATERIAL FOR THE EMBANKMENT IS FREE OF ROOTS, WOODY VEGETATION, ORGANIC MATTER, AND OTHER OBJECTIONABLE MATERIAL. PLACE THE FILL IN LIFTS NOT TO EXCEED 9 INCHES, AND MACHINE COMPACT IT. OVER FILL THE EMBANKMENT 6 INCHES TO ALLOW FOR SETTLEMENT. 3. SHAPE THE BASIN TO THE SPECIFIED DIMENSIONS. PREVENT THE SKIMMING DEVICE FROM SETTLING INTO THE MUD BY EXCAVATING A SHALLOW PIT UNDER THE SKIMMER OR PROVIDING A LOW SUPPORT UNDER THE SKIMMER OF STONE OR TIMBER. 4. PLACE THE BARREL (TYPICALLY 4—INCH SCHEDULE 40 PVC PIPE) ON A FIRM, SMOOTH FOUNDATION OF IMPERVIOUS SOIL. DO NOT USE PERVIOUS MATERIAL SUCH AS SAND, GRAVEL OR CRUSHED STONE AS BACKFILL AROUND THE PIPE. PLACE THE FILL MATERIAL AROUND THE PIPE SPILLWAY IN 4—INCH LAYERS AND COMPACT IT UNDER AND AROUND THE PIPE TO AT LEAST THE SAME DENSITY AS THE ADJACENT EMBANKMENT. CARE MUST BE TAKEN NOT TO RAISE THE PIPE FROM THE FIRM CONTACT WITH ITS FOUNDATION WHEN COMPACTING UNDER THE PIPE HAUNCHES. 5. ASSEMBLE THE SKIMMER FOLLOWING THE MANUFACTURERS INSTRUCTIONS, OR AS DESIGNED. 6. LAY THE ASSEMBLED SKIMMER ON THE BOTTOM OF THE BASIN WITH THE FLEXIBLE JOINT AT THE INLET OF THE BARREL PIPE. ATTACH THE FLEXIBLE JOINT TO THE BARREL AND POSITION THE SKIMMER OVER THE EXCAVATED PIT OR SUPPORT. BE SURE TO ATTACH A ROPE TO THE SKIMMER AND ANCHOR IT TO THE SIDE OF THE BASIN. THIS WILL BE USED TO PULL THE SKIMMER TO THE SIDE FOR MAINTENANCE. 7. EARTHEN SPILLWAYS — INSTALL THE SPILLWAY IN UNDISTURBED SOIL TO THE GREATEST EXTENT POSSIBLE. THE ACHIEVEMENT OF PLANNED ELEVATIONS, GRADE, DESIGN WIDTH, AND ENTRANCE AND EXIT CHANNEL SLOPES ARE CRITICAL TO THE SUCCESSFUL OPERATION OF THE SPILLWAY. THE SPILLWAY SHOULD BE LINED WITH LAMINATED PLASTIC OR IMPERMEABLE GEOTEXTILE FABRIC. THE FABRIC MUST BE WIDE AND LONG ENOUGH TO COVER THE BOTTOM AND SIDES AND EXTEND ONTO THE TOP OF THE DAM FOR ANCHORING IN A TRENCH. THE EDGES MAY BE SECURED WITH 8—INCH STAPLES OR PINS. THE FABRIC MUST BE LONG ENOUGH TO EXTEND DOWN THE SLOPE AND EXIT ONTO STABLE GROUND. THE WIDTH OF THE FABRIC MUST BE ONE PIECE, NOT JOINED OR SPLICED; OTHERWISE WATER CAN GET UNDER THE FABRIC. IF THE LENGTH OF THE FABRIC IS INSUFFICIENT FOR THE ENTIRE LENGTH OF THE SPILLWAY, MULTIPLE SECTIONS, SPANNING THE COMPLETE WIDTH, MAY BE USED. THE UPPER SECTION(S) SHOULD OVERLAP THE LOWER SECTION(S) SO THAT WATER CANNOT FLOW UNDER THE FABRIC. SECURE THE UPPER EDGE AND SIDES OF THE FABRIC IN A TRENCH WITH STAPLES OR PINS. 8. INLETS — DISCHARGE WATER INTO THE BASIN IN A MANNER TO PREVENT EROSION. USE TEMPORARY SLOPE DRAINS OR DIVERSIONS WITH OUTLET PROTECTION TO DIVERT SEDIMENT —LADEN WATER TO THE UPPER END OF THE POOL AREA TO IMPROVE BASIN TRAP EFFICIENCY. 9. EROSION CONTROL — CONSTRUCT THE STRUCTURE SO THAT THE DISTURBED AREA IS MINIMIZED. DIVERT SURFACE WATER AWAY FROM BARE AREAS. COMPLETE THE EMBANKMENT BEFORE THE AREA IS CLEARED. STABILIZE THE EMERGENCY SPILLWAY EMBANKMENT AND ALL OTHER DISTURBED AREAS ABOVE THE CREST OF THE PRINCIPAL SPILLWAY IMMEDIATELY AFTER CONSTRUCTION. 10. INSTALL POROUS BAFFLES. 11. AFTER ALL THE SEDIMENT —PRODUCING AREAS HAVE BEEN PERMANENTLY STABILIZED, REMOVE THE STRUCTURE AND ALL THE UNSTABLE SEDIMENT. SMOOTH THE AREA TO BLEND WITH THE ADJOINING AREAS AND STABILIZE PROPERLY. 12.

INSPECT SKIMMER SEDIMENT BASINS AT LEAST WEEKLY AND AFTER EACH SIGNIFICANT (ONE—HALF INCH OR GREATER) RAINFALL EVENT AND REPAIR IMMEDIATELY. REMOVE SEDIMENT AND RESTORE THE BASIN TO ITS ORIGINAL DIMENSIONS WHEN SEDIMENT ACCUMULATES TO ONE—HALF THE HEIGHT OF THE FIRST BAFFLE. PULL THE SKIMMER TO ONE SIDE SO THAT THE SEDIMENT UNDERNEATH IT CAN BE EXCAVATED. EXCAVATE THE SEDIMENT FROM THE ENTIRE BASIN, NOT JUST AROUND THE SKIMMER OR THE FIRST CELL. MAKE SURE VEGETATION GROWING IN THE BOTTOM OF THE BASIN DOES NOT HOLD DOWN THE SKIMMER. 2. REPAIR THE BAFFLES IF THEY ARE DAMAGED. RE —ANCHOR THE BAFFLES IF WATER IS FLOWING UNDERNEATH OR AROUND THEM. 3. IF THE SKIMMER IS CLOGGED WITH TRASH AND THERE IS WATER IN THE BASIN, USUALLY JERKING ON THE ROPE WILL MAKE THE SKIMMER BOB UP AND DOWN AND DISLODGE THE DEBRIS AND RESTORE FLOW. IF THIS DOES NOT WORK, PULL THE SKIMMER OVER TO THE SIDE OF THE BASIN AND REMOVE THE DEBRIS. ALSO CHECK THE ORIFICE INSIDE THE SKIMMER TO SEE IF IT IS CLOGGED; IF SO REMOVE THE DEBRIS. 4. IF THE SKIMMER ARM OR BARREL PIPE IS CLOGGED, THE ORIFICE CAN BE REMOVED AND THE OBSTRUCTION CLEARED WITH A PLUMBER'S SNAKE OR BY FLUSHING WITH WATER. BE SURE AND REPLACE THE ORIFICE BEFORE REPOSITIONING THE SKIMMER. 5. CHECK THE FABRIC LINED SPILLWAY FOR DAMAGE AND MAKE ANY REQUIRED REPAIRS WITH FABRIC THAT SPANS THE FULL WIDTH OF THE SPILLWAY. CHECK THE EMBANKMENT, SPILLWAYS, AND OUTLET FOR EROSION DAMAGE, AND INSPECT THE EMBANKMENT FOR PIPING AND SETTLEMENT. MAKE ALL NECESSARY REPAIRS IMMEDIATELY. REMOVE ALL TRASH AND OTHER DEBRIS FROM THE SKIMMER AND POOL AREAS. 6. FREEZING WEATHER CAN RESULT IN ICE FORMING IN THE BASIN. SOME SPECIAL PRECAUTIONS SHOULD BE TAKEN IN THE WINTER TO PREVENT THE SKIMMER FROM PLUGGING WITH ICE. NORTH CAROLINA BOARD OF EXAMINERS FOR ENGINEERS AND SURVEYORS LICENSE NO.
