Project Summary This design-build project includes development of a 21-acre site for the 2"d Radio Battalion located in the Wallace Creek area of Camp Lejeune in the northeast quadrant of the intersection of Holcomb Blvd and Wilson Boulevards. Development includes construction of a 26,000 SIFT Tactical Equipment Maintenance Building, a Hazardous Material Storage Building, a four-bay exterior vehicle wash rack, and a 30,000 SFT tactical vehicle parking area. Development includes access roads, utilities and infrastructure to support the primary building construction as well as development of pad sites and support infrastructure for two future buildings programmed for the area. T / A, SITE / 111 �:yy � I III ,�{ �► __�'���'1'I� (�}. A FIGURE 1: PROPOSED SITE PLAN 2 i Basis of Design wastewater pump station on the 2nd Battalion Access Road which has a rated capacity of 500 gpm. This pump station was previously designed to accommodate the proposed development, I I (Camp Lejeune Pump Station #SWC513). No new capacity improvements at the pump station or Camp Lejeune regional wastewater treatment plant are required to support this project. Appendix A includes detailed wastewater design calculations, including pipe and pump sizing, velocity, pump cycle times and level control settings, pump station buoyancy, wet well storage, surge protection, detention time in the wet well and force main, ability to flush low points in force mains with a pump cycle, and confirmation of the downstream lift station capacity. Appendix B includes and sewer system plans and specifications describing all materials to be j used, methods of construction, and means for assuring the quality and integrity of the finished j project in accordance with NCAC requirements. All utility crossing points are designed to provide edge to edge clearances per NC code 1 requirements with fittings and offsets used as needed to achieve required separation to j underground sanitary sewer and storm drainage piping. D. NC DENR Minimum Pump Station Design Criteria The following is a summary of minimum design criteria incorporated into the proposed pump station design following current Title 15A NCAC Section 2T.0300 requirements: 1. Total dynamic head for the pump station design flow of 65 gpm (one pump running, including minor losses) is 13.5'. 2. System curve indicates flow of 65 p p y gpm is achieved at total head of u to 22' (copy attached in Appendix A). 3. Pump station cycle time indicates 3" force main purge volume (404 gallons is required per pump cycle) and 2.8' normal pump cycle depth provides full flushing of force main each pump cycle (404 gallons per individual pump cycle). 4. Pump station buoyancy based on total site flooding checked, non-buoyant, not located within 100 year floodplain area (ground elevation at pump station NAVD88 = 21.31'; nearest 100yr flood level at Elev. 7.00 600' away from site). 5. Duplex grinder pump station serving one occupied building; provisions for emergency pump and generator connection included in pump station design. Direct wiring of emergency power is not required. Local high level alarm setting provides 231 gallons of storage until gravity invert is reached (provides 29 minutes of response time at ADF of 8 GPM from time lag pump activates until alarm sounds; sufficient for local response with emergency generator or pumping equipment. 6. Minimum self cleaning velocity of 3.1 fps in force main is achieved. 7. MCB Camp Lejeune Utilities staff confirmed receiving pump station was sized for project flow, existing pump station capacity is listed as 500 gpm. 4 Basis of Design 18. Pumps have been selected with motor service factors of 1.25, NEMA Service Class F to ensure resiliency and reliability. 19. Pump wet well cycle and run times result in less than 2 starts per hour at ADF (540 gph). The cycle volume of 404 gallons was selected as the preferred design limitation vs min. 2 cycles per hour to appropriately purge and cleanse full volume of the force main each pump cycle. At ADF the pump station will cycle 4 times every three hours which will be appropriate given the relatively low wastewater flow volumes at this station. At 65 gpm design flowrate the pumps will run for approximately 6 minutes each cycle allowing pumps to reach operating speed and not short cycle. The pumps will remain submerged to reduce corrosion potential and all stainless steel hardware and corrosion resistant materials are included within the pump station. 20. Pump off level is specified to keep the pumps submerged at all times;this will reduce potential for air entrainment or cavitation in accordance with manufacturer's recommended operating levels. f 21. Pump station is designed as a precast concrete structure with watertight joints and cover; top elevation is set 6" above grade to avoid potential for stormwater intrusion. 22. Pump station is located adjacent to paved access road to industrial portion of the site 1 where it will be accessible but not intrusive or create potential nuisance conditions for the site occupants. 23. Chain link fencing (8' height) is provided around the pump station to provide site security. 24. Site lighting is provided as required for maintenance access around the pump station site. 25. OSHA required signage regarding confined spaces and access control contact numbers are provided on entry gate into the pump station area. ! 26. Wetwell is designed with a sloped invert to direct solids into pumping equipment and avoid accumulation of solids within the pump station. 27. Pumps will remain full submerged during operating cycles. 1 i 28. Each pump is rail mounted with watertight bayonet fittings connecting to 3" pipe discharge manifold whereas velocity is maintained between 2-8 fps (3.1 fps at design flow). i 29. Isolation ball valves are provided on each pump so individual pumps can remain in service as alternate pump is taken out for maintenance. Check valves are provided on discharge piping between isolation valve and the pump to control backflow during normal pump operations; check valves are installed in a horizontal orientation within valve vault adjacent to the pump station. 30. Flexible, watertight connections are used for all core-drilled or cast-in-place pipe penetrations in and out of the pump station and to the adjacent valve vault to allow for potential differential settlement between the structures. 6 { Basis of Design F I 3. Piping is specified to be anchored in to structures with stainless steel hardware to limit movement and resist thrust forces. All HDPE piping is integrally restrained as it is thermally fused together; where HDPE piping enters the gravity discharge manhole it is secured using stainless steel hardware designed to match pipe pressure rating (125 psi) which exceeds the 1.25x shutoff operating pressure of the pump shut-off head. 4. The force main is designed with combination air/vacuum relief valves to limit potential for air binding or blockage within the force main; this will also ensure the force main drains out properly during maintenance activity. 5. Water hammer and transients will not be a concern with this force main system due to the low operating pressures, atmospheric discharge pressure and velocities maintained below 5 fps in the force main. ! 6. Force main has been designed with a minimum depth of cover to the crown of the pipe of 3 feet. 7. The force main is routed alongside new road alignments to permit ease of access for maintenance and repair while providing required separation to adjacent utilities in accordance with Title 15A NCAC 2T .0305(f). i 8. Force main routing is buried within road embankment fill section where stream crossing is required; no aerial crossings or exposed sections of the force main piping are included within the project. 9. Commissioning of the force main shall include hydrostatic pressure and leakage testing of the force main and associated appurtenances to minimum pressure of 1.5x maximum operating pressure of the force main (125 psi design pressure of the force main piping)as part of commissioning in accordance with NCAC requirements. 10. Force main leakage test may be conducted simultaneously or separate from the hydrostatic test but shall be at the same test pressure; no visible leakage will be acceptable from the force main; allowable leakage will be limited to measuring the amount of water required to maintain pressure within 5 psi of the test pressure (after pressure has stabilized and all air is j expelled). Allowable volume of leakage shall not exceed based on NCAC leakage formula: L=SD(P)^.5)/133,200 or 0.28 gal/hr based on 1,100 feet of 3" pipe tested to 125 psi. i F. NC DENR Minimum Electrical and Controls Design Criteria The following is a summary of minimum design criteria incorporated into the proposed pump station electrical equipment design following current Title 15A NCAC Section 2T.0300 requirements: 1. All electrical components and systems are designed in accordance with the National Electrical Code (NFPA 70) and applicable federal, state and local codes. I 2. All pump station electrical connections, controls and alarms are located above grade in a stainless steel NEMA 3R rated exterior electrical enclosure. 8 1 I Basis of Design 4.

Good Morning Jordan— This is Phase 2 of the 2"d Radio Battalion campus development and the existing lift station and wastewater collection system were previously designed to support this component during Phase I with design flows at the receiving lift station confirmed at 500 gpm. The design flows on this project will contribute less than 2%of the design flow to this existing lift station. All flows remain internal to MCB-CUN and existing treatment plant and the user group is an existing flow to the plant so our understanding the FTSE was not applicable. If this is something we need to have Camp Lejeune submit please let me know; attached is the e-mail from the base official confirming the downstream lift station capacity we referenced during design. Thanks for your help with this project. Best Regards, Tom THOMAS L.
