The leachate then passes through another geotextile at the leachate lagoon before entering the proposed leachate pump station wet well. Therefore, solids handling is not a requirement for the proposed pump station. Vertical turbine pumps have been selected due to the high head conditions and a screen will be provided on the intake of the pump as recommended by the manufacturer to prevent solids from entering the pump and causing damage. Additionally, the wet well will be cleaned as needed to remove any grit or sand that settles in the floor of the structure. Since solids are not expected to enter the wet well, fillets and sloped wet well floors are not proposed. The wet well will feature a dual contained HDPE liner attached to the inside of the concrete manhole. Constructability of this installation is best without irregular shapes in the floor of the structure. A variance is requested on solids handling and sloping of the wet well floor to meet the pumping conditions with the highest efficiency and improve constructability since solids will not enter the wet well. Backup Power The landfill currently owns and operates all facilities needed for continuing the pump and haul operations of all existing and future leachate to the wastewater treatment plant. Also the existing leachate storage lagoon, which is hydraulically connected to the wet well, has a storage capacity of approximately 1,000,000 gallons and provides storage for approximately 59 days of the future average leachate production at the landfill. This storage capacity is more than adequate for any anticipated power outage, especially since the landfill owns several gas or diesel operated pumps capable of loading tanker trucks for pumping- and hauling leachate to the wastewater treatment plant, if required. Due to the available storage capacity and the pump and haul operation currently used, the landfill does not intend to install a permanent generator for the proposed pump station at this time. However, the pump station will be designed for emergency power that may be supplied by a temporary generator if conditions at the landfill change. A backup power source could be installed but will provide little benefit or added security against potential overflow. A variance to the requirement for a backup power source is requested due to the other backup and leachate storage available at this facility. 3. Pump Cycle Times The MDC requires the pumps to operate between two and eight times per hour. The proposed vertical turbine pumps are designed for continuous duty. The existing leachate storage lagoon is approximately 10 foot deep and the pumps will be set to start when leachate reaches an approximate depth of 1 foot in the leachate lagoon. This will allow continuous operation of the pumps for 20 — 30 hours and avoid unnecessary starting and stopping. A variance is requested to allow alternate pump cycle times due to the large volume in the leachate storage lagoon. 4. Security The pump station site is located within the landfill property and access to the pump station area will be limited to landfill employees only. Access to the landfill is restricted as required by the solid waste rules. The public is allowed to access the working face of the landfill and the recycling areas during normal operating hours, but are not allowed to free roam the facility. The gate to the landfill is locked after regular operating hours. A security fence is not proposed around the pump station area. Wet well access is intended to remain in a locked position and the main control panel will be locked. A security fence will be difficult to install and would interfere with other landfill operations due to the limited amount of space in and around the proposed pump station area. A variance is requested for the requirement to provide fencing around the pump station site. 5. Valves on Suction Line Valves are typically never used on the suction side of the pump piping and provide no operational value. The introduction of valves into the suction column may cause problems with balance and pump operation. A variance is requested to remove the requirement for valves on the suction piping of the pump. 6. Pump Controls Under normal operating conditions, the City of Albemarle does not desire to have automatic operation of the lag pump. In the event operation of the lag pump is required, the pump will be started manually. Also, backup battery power source for the alarms and telemetry are not specified for the pump station. Due to the significant amount of storage in the leachate storage lagoon and the management practices for leachate on the landfill, these features provide little added benefit. The level of leachate in the lagoon and the status of the pump station will be checked at least daily. Leachate management for the landfill is a constant requirement and cannot be managed such that an overnight power outage or other pump shutdown could lead to a discharge. If the lag pump was programmed to start automatically, unintentionally increasing flow to the wastewater collection system may occur. A variance is requested to allow the lag pump to be started manually when needed in lieu of automatically. 7. Dostrearr Capacity Evaluation The proposed leachate force main will discharge into the City's existing 8" diameter gravity sewer line. The average and peak flows for this 8" diameter line was evaluated with the addition of both 80 gpm and 110 gpm from the proposed leachate force main. Based on a peaking factor of 2.5 on the existing flows and the addition of leachate flows, the existing 8" diameter gravity sewer will only reach 69 to 85 percent capacity. These calculations are provided in Appendix B of the Design Calculations. The existing 8" diameter gravity sewer that will receive leachate ties into an existing 12" diameter gravity sewer that receives flow from an additional portion of the City of Albemarle. This 12" diameter gravity sewer connects to other gravity sewer lines of increasing diameter in route to the wastewater treatment plant. The City of Albemarle Water and Sewer Department advised that the 12" diameter sewer main has available capacity to accept the average leachate flow from the proposed leachate pump station during dry conditions, but is near capacity during wet weather peak flow conditions. Therefore, no leachate will be pumped to the collection system during wet weather conditions determined by the City. There are no pump stations in between the tie-in point of the force main and the wastewater treatment plant. No further evaluation has been performed on the 12" diameter sewer main and other downstream mains. The City of Albemarle owns and operates the landfill, wastewater treatment plant and the wastewater collection system. Since opening of the landfill in 1999, the City has managed the transportation and treatment of leachate at the wastewater treatment plant. Since both the landfill and the wastewater collection and treatment systems are controlled by one owner and the leachate storage lagoon has significant storage capacity, the proposed leachate pump station can be operated under conditions of optimum capacity in the collection system and treatment plant. In order to ensure safe delivery of leachate without exceeding pipe and treatment capacities, the manager of the wastewater collection and treatment system for the City will determine the operational times for the leachate pump station. In the event capacity is not available in the collection system and storage in the leachate lagoon is limited, the landfill will continue to pump and haul leachate to the treatment plant as is currently being executed successfully. The capacity of the existing 12" diameter terracotta gravity sewer at the minimum allowed slope is approximately 696 gpm. Assuming peak hourly flow during wet weather conditions in the existing 12" gravity line is only twice the average daily flow, approximately 348 gpm of capacity will be availableduring normal (off peak periods). This provides sufficient capacity for the proposed leachate pump station during off peak dry weather conditions. Based on the information provided by the City's water and sewer staff, sufficient capacity is not available in the existing downstream gravity sewer to allow uninterrupted leachate flows from the landfill during wet weather conditions. Therefore, flows from the proposed pump station will need to be continually managed by City staff. The pump station will be utilized during dry periods and pump and haul operations will supplement transportation of leachate during wet weather periods if required. A variance is requested to allow operation of the leachate pump station as directed by the City's water and sewer staff in order to successfully manage pipe and treatment capacities.

Flows allocated through interlocal agreements or other contracts not yet contributing flow to the collection system are also included. For POTWs that implement a pretreatment program, include flows allocated to industrial users who may not be using all of their flow allocation. Please contact your Pretreatment Coordinator for information on industrial flow tributary to your WWTP. As of January 15, 2008 the POTW should have reviewed flow allocations made over the last two years and reconciled their flow records, to the best of their ability, so it is known how much flow has been obligated and is not yet been made tributary to the WWTP, in accordance with local policies and procedures employed by the reporting entity. The obligated flow not yet tributary plus actual flow will be reconciled annually for systems at less than 60% of permitted flow used. Annual updates shall be submitted to the appropriate Regional Office by January 15 of each year and cover the previous calendar year. Semi -Annual updates shall be required when the percent of permitted flow used reaches 60%. Semi- annual time period are defined as January 1 through June 30 and July I through December 31. Semi- annual updates shall be submitted to the appropriate Regional Office by July 15 and January 15 of each year. Quarterly updates shall be required when the percent of permitted flow used reaches 80%. Quarters are defined as Qtrl (Jan -Feb -Mar); Qtr2 (Apr -May -Jun); Qtr3 (JuI-Aug-Sep); Qtr4 (Oct -Nov -Dec).

The annual average flow for 2007 is 2.7 MGD. There is a proposed flow expansion of 0.015 MGD. The first Form FTSE submitted after January 15, 2008 may have numbers like this: c. = 6.0 MGD d. = 0.5 MGD e.=2.7 MGD f. = 0.015 MGD g. = 3.215 MGD h.=53.6% The next Form FTSE may be updated like this with a proposed flow expansion of 0.102 MGD: c. = 6.0 MGD d. = 0.515 MGD e. = 2.73 MGD f. = 0.102 MGD g. = 3.349 MGD h. = 55.8 % Each subsequent Form FTSE- will be updated in the same manner. Section 1 List the pump station name or number and approximate pump station firm capacity, approximate design average daily flow (A) approximate current average daily flow (B), and the obligated, not yet tributary flow through the pump station (C) for each pump station that will be impacted by the proposed sewer extension project. Calculate the total current flow plus obligated flow (D=B+C) and the available capacity (E=A-D). Include the proposed flow for this project with other obligated flows that have been approved for the pump station but are not yet tributary (C). Firm capacity is the maximum pumped flow that can be achieved with the largest pump out of service as per the Minimum Design Criteria. Design Average Daily Flow is the firm capacity of the pump station divided by a peaking factor (pf) of not less than 2.5. If the available capacity (E) for any pump station is < 0, then prepare a planning assessment for that pump station if the system has future specific plans related to capacity that should be considered in the permitting process.

A planning assessment for Kaw Creek PS (see example data above) may be performed to evaluate whether there is significant likelihood that needed improvements or reductions in obligated flows will be in place prior to activating the flows from the proposed sewer extension project. If the system decides to accept the flow based on a planning assessment addendum, it is responsible to manage the flow without capacity related sanitary overflows and must take all steps necessary to complete the project or control the rate of flow to prevent sanitary sewer overflows. The planning assessment may identify a funded project currently in design or construction, or a planned project in the future not yet funded but in a formal plan adopted by the system. The system should carefully weigh the certainty of successful timely project completion for any expansion, flow management diversion or infiltration and inflow elimination projects that are the foundation of a planned solution to capacity tracking and acceptance compliance. For example: Given that: a. The proportion and amount of obligated, not yet tributary flow accounts for 24 % and 0.080 MGD of the committed flow in Pump Station Kaw Creek; and that b. The rate of activation of this obligated, not yet tributary capacity is currently approximately 0.01 MGD per year; and that c. A funded capital project that will provide the required planned capacity, namely is in design or under construction with planned completion in ; and/or d. The following applies: The master plan and ten year capital plan contain recommended scope and funding for a capital project entitled Kaw Creek Pump Station upgrade with funding planned in July 2014. This project is planned to add 0.100 MGD to the firm capacity of the pump station by October 20I5. Inclusion of this proposed capital project as a condition of this Flow Tracking/Acceptance for Sewer Extension Permit Application elevates this project's priority for funding and construction to be implemented ahead of the activation of obligated, not vet tributary flows in amounts that exceed the firm pump station capacities identified in Section II above. Therefore: Given reasonably expected conditions and planning information, there is sufficient justification to allow this flow to be permitted, without a significant likelihood of over -allocating capacity in the system infrastructure.

VARIANCE REQUEST FROM MINIMUM DESIGN CRITERIA (MDC) 1. Requirement to Pass a Three -Inch Solid and Solids Collection in Wet Well The leachate at the landfill is filtered through the ASTM No. 57 leachate collection stone, perforated pipe and a non -woven geotextile inside the landfill before being delivered to the leachate storage lagoon. The leachate then passes through another geotextile at the leachate lagoon before entering the proposed leachate pump station wet well. Therefore, solids handling is not a requirement for the proposed pump station. Vertical turbine pumps have been selected due to the high head conditions and a screen will be provided on the intake of the pump as recommended by the manufacturer to prevent solids from entering the pump and causing damage. Additionally, the wet well will be cleaned as needed to remove any grit or sand that settles in the floor of the structure. Since solids are not expected to enter the wet well, fillets and sloped wet well floors are not proposed. The wet well will feature a dual contained HDPE liner attached to the Inside of the concrete manhole. Constructability of this installation is best without irregular shapes in the floor of the structure. A variance is requested on solids handling and sloping of the wet well floor to meet the pumping conditions with the highest efficiency and improve constructability since solids will not enter the wet well. 2. Backup Power The landfill currently owns and operates all facilities needed for continuing the pump and haul operations of all existing and future leachate to the wastewater treatment plant. Also the existing leachate storage lagoon, which is hydraulically connected to the wet well, has a storage capacity of approximately 1,000,000 gallons and provides storage for approximately 59 days of the future average leachate production at the landfill. This storage capacity is more than adequate for any anticipated power outage, especially since the landfill owns several gas or diesel operated pumps capable of loading tanker trucks for pumping and hauling leachate to the wastewater treatment plant, if required. Due to the available storage capacity and the pump and haul operation currently used, the landfill does not intend to install a permanent generator for the proposed pump station at this time. However, the pump station will be designed for emergency power that may be supplied by a temporary generator if conditions at the landfill change. A backup power source could be installed but will provide little benefit or added security against potential overflow. A variance to the requirement for a backup power source is requested due to the other backup and leachate storage available at this facility. 3. Pump Cycle Times The MDC requires the pumps to operate between two and eight times per hour. The proposed vertical turbine pumps are designed for continuous duty. The existing leachate storage lagoon is approximately 10 foot deep and the pumps will be set to start when leachate reaches an approximate depth of 1 foot in the leachate lagoon. This will allow continuous operation of the pumps for 20 -- 30 hours and avoid unnecessary starting and stopping. A variance is requested to allow alternate pump cycle times due to the large volume in the leachate storage lagoon. 4. Security The pump station site is located within the landfill property and access to the pump station area will be limited to landfill employees only. Access to the landfill is restricted as required by the solid waste rules. The public is allowed to access the working face of the landfill and the recycling areas during normal operating hours, but are not allowed to free roam the facility. The gate to the landfill is locked after regular operating hours. A security fence is not proposed around the pump station area. Wet well access is intended to remain in a locked position and the main control panel will be locked. A security fence will be difficult to install and would interfere with other landfill operations due to the limited amount of space in and around the proposed pump station area. A variance is requested for the requirement to provide fencing around the pump station site. 5. Valves on Suction Line Valves are typically never used on the suction side of the pump piping and provide no operational value. The introduction of valves into the suction column may cause problems with balance and pump operation. A variance is requested to remove the requirement for valves on the suction piping of the pump. 6. Pump Controls Under normal operating conditions, the City of Albemarle does not desire to have automatic operation of the lag pump. In the event operation of the lag pump is required, the pump will be started manually. Also, backup battery power source for the alarms and telemetry are not specified for the pump station. Due to the significant amount of storage in the leachate storage lagoon and the management practices for leachate on the landfill, these features provide little added benefit. The level of leachate in the lagoon and the status of the pump station will be checked at least daily. Leachate management for the landfill is a constant requirement and cannot be managed such that an overnight power outage or other pump shutdown could lead to a discharge. If the lag pump was programmed to start automatically, unintentionally increasing flow to the wastewater collection system may occur. A variance is requested to allow the lag pump to be started manually when needed in lieu of automatically. 7. Downstream Capacity Evaluation The proposed leachate force main will discharge into the City's existing 8" diameter gravity sewer line. The average and peak flows for this 8" diameter line was evaluated with the addition of both 80 gpm and 110 gpm from the proposed leachate force main. Based on a peaking factor of 2.5 on the existing flows and the addition of leachate flows, the existing 8" diameter gravity sewer will only reach 69 to 85 percent capacity. These calculations are provided in Appendix B of the Design Calculations. The existing 8" diameter gravity sewer that will receive leachate ties into an existing 12" diameter gravity sewer that receives flow from an additional portion of the City of Albemarle. This 12" diameter gravity sewer connects to other gravity sewer lines of increasing diameter in route to the wastewater treatment plant. The City of Albemarle Water and Sewer Department advised that the 12" diameter sewer main has available capacity to accept the average leachate flow from the proposed leachate pump station during dry conditions, but is near capacity during wet weather peak flow conditions. Therefore, no leachate will be pumped to the collection system during wet weather conditions determined by the City. There are no pump stations in between the tie-in point of the force main and the wastewater treatment plant. No further evaluation has been performed on the 12" diameter sewer main and other downstream mains. The City of Albemarle owns and operates the landfill, wastewater treatment plant and the wastewater collection system. Since opening of the landfill in 1999, the City has managed the transportation and treatment of leachate at the wastewater treatment plant. Since both the landfill and the wastewater collection and treatment systems are controlled by one owner and the leachate storage lagoon has significant storage capacity, the proposed leachate pump station can be operated under conditions of optimum capacity in the collection system and treatment plant. In order to ensure safe delivery of leachate without exceeding pipe and treatment capacities, the manager of the wastewater collection and treatment system for the City will determine the operational times for the leachate pump station. In the event capacity is not available in the collection system and storage in the leachate lagoon is limited, the landfill will continue to pump and haul leachate to the treatment plant as is currently being executed successfully. The capacity of the existing 12" diameter terracotta gravity sewer at the minimum allowed slope is approximately696 gpm. Assuming peak hourly flow during wet weather conditions in the existing 12" gravity line is only twice the average daily flow, approximately 348 gpm of capacity will be available during normal (off peak periods). This provides sufficient capacity for the proposed leachate pump station during off peak dry weather conditions. Based on the information provided by the City's water and sewer staff, sufficient capacity is not available in the existing downstream gravity sewer to allow uninterrupted leachate flows from the landfill during wet weather conditions. Therefore, flows from the proposed pump station will need to be continually managed by City staff. The pump station will be utilized during dry periods and pump and haul operations will supplement transportation of leach ate during wet weather periods if required. A variance is requested to allow operation of the leachate pump station as directed by the City's water and sewer staff in order to successfully manage pipe and treatment capacities. FT.

PROJECT SUMMARY Fhe City of Albemarle owns and operates a Municipal Solid Waste (MSW) landfill, a Construction and Demolition (C&D) Landfill and a recycling center. The landfill is located on Stony Gap Road approximately one mile east of NC State Highway South Business 52, The landfill generates an average of 13,900 gallons of leachate per day. The leachate is treated at the City of Albemarle \Vastewater 'Treatment Plant (WIAITP). The City operates f Commerce Boulevard, Suite 110 • Savannah, (eorgia. 31 405 • (9.12) 298-0230 • Fax (912) 298,-0234 • www..h.hn.tcont NiAcoN • ATLANTA • Savannah • STATHRop.o•BRuNswicK Mr. Barry Lose June 3, 2016 Page 2 of 2 the WWTP and maintains a wastewater collection system that collects and transports wastewater to the W'TP. 'rhe City anticipates that the landfill will continue to operate for 50 years or longer. Currently, leachate generated by the 1 uid fi 11 drains to a leachate storage lagoon designed with a composite liner system to contain all leachate. The leachate is stored in the lagoon until taken to the WWTP for treatment. The City utilizes a "pump and haul." operation to deliver leachate to the WWIP or to a gravity manhole location Within the City's collection system. This operation consists of pumping the stored leachate from a set well located adjacent to the leachate storage lagoon into tanker trucks positioned adjacent to the pump manhole. Once loaded, the tanker trucks transport the leachate to a manhole within the City's wastewater collection system. The leachate is discharged to the manhole Which allows some mixing of the leachate with other wastewater in the system. Landfill leachate may contain metals and other parameters not typically contained in municipal. wastewater; therefore, it is best that the plant not receive large slugs of leachate at one time that may disrupt plant operations. '1 he City proposes to supplement the pump and haul operation with a new force main and pump station adjacent to the leachate storage lagoon. 'The proposed .force main will traverse the landfill property until reaching Stony Gap Road, 'Fhe force main will he constructed in the right-of-way of Stony Gap Road and South Business 52 until reaching a gravity manhole within the City's Wastewater collection system„ The new force main will reduce operating- cost for the landfill and significantly improve the landfill's leachate handling, capabilities. The force main will allow the City to better control the -flows and timing for the delivery of the leachate to the WWTP„ Additionally the 'force main will eliminate approximately 900 tanker trips per year and reduce the potential for leachate spills from the tanker truck during loading, unloading and transporting.
