Property owners shall maintain, operate, and repair stormwater drainage systems in compliance with the requirements of the 2021 King County Surface Water Design Manual (KC SWDM). All stormwater systems shall be inspected on a periodic basis as described in the KC SWDM. The King County Stormwater Pollution Prevention Manual (KC SPPM) shall be used to identify best management practices (BMPs) for managing stormwater on commercial properties. In accordance with TMC 14.30.100, maintenance inspections shall be conducted by a third -party inspector. Maintenance agreement(s) for third -party maintenance of this property are provided in Appendix A. A sample Inspection form is provided in Appendix B. 3 Best Management Practices The most effective way to maintain your water quality facility is to prevent pollutants from entering the facility in the first place. Common pollutants include sediment, trash & debris, chemicals, dog wastes, runoff or leaks from stored materials, illicit discharges into the stormwater system (like car wash or pressure washing runoff) and many others. The below measures address these potential contaminants and are used to save time and money in the long run. • Educate property owners/operators to be aware of the onsite stormwater treatment facilities and conveyance system and make them aware of how their actions affect water quality. • Keep impervious areas onsite free of trash, debris, and plant litter. • Ensure the proper handling, storage and disposal of hazardous wastes and chemicals. • Plan landscaping care to minimize the use of chemicals and pesticides. • Sweep paved surfaces and dispose of sweeping waste properly. • Be aware of fluids leaking from vehicles. Stop active leaks and use absorbents to soak up leaked fluids. Dispose of absorbent material properly. • Re -vegetate disturbed and bare areas to maintain vegetative stabilization if soil erosion is causing turbid water to discharge to the stormwater system. • Clean out stormwater system components when necessary including inlets, conveyance lines, lift stations and treatment systems.

Waste wash water must be directed to the sanitary sewer or collected for off-site disposal. Source control best management practices (BMPs) as identified in the KC SPPM are required to reduce or eliminate the release of pollution. See Appendix F for BMPs applicable to this property. 4 Safety Never enter or direct an employee to enter a confined space (vault, manhole, etc.) without proper training and equipment. See WAC 296.809 regarding confined space rules and regulations. There are no site-specific hazards located at the facility. If a toxic or flammable substance is discovered, leave the immediate area, and call 911. Potentially dangerous substance (e.g., fuel, chemicals, hazardous materials) situations must be referred to the local Fire Department immediately for response by the Hazardous Materials Unit. 5 General Location and Description of Stormwater Management Facilities The facility site plan, showing locations of all stormwater infrastructure (i.e. catch basins, conveyance, lift stations and treatment systems) is located in Appendix C. There are two separate conveyance systems onsite. Each conveyance system is routed to the west side of the property where water is pumped through treatment prior to discharging to the Duwamish River. NORTH LIFT STATION: The north treatment system is located in the northwest corner of the property. Water from the north conveyance system enters CB#1 and is routed north to the lift station. The north lift station is a duplex pump system capable of pumping 360 gpm (single pump) and 720 gpm (dual pump). Water is pumped into a Contech Vortex® separator vault where coarse solids and oil is trapped. Water then gravity flows to the west into CAtchrnent LLC Stormwater O&M Manual CenterPoint Tukwila April 19, 2023 3 Instrument Number: 20230605000873 Document:COV Rec: S330.50 Page -23 of 128 Record Date:6/5/2023 4:14 PM King County, WA a Contech StormFilter® with 96 ZPG cartridges capable of treating up to 720 gpm. Treated water enters the outlet chamber before being routed into a pipe that discharges into a still well just to the south. This pipe has a flap gate installed preventing backflow during high tides. The outlet pipe to the Duwamish River is located in the still well. High flow bypass is available through a high outlet in CB#1 and is routed west to the still well. A flap gate on the discharge pipe from CB#1 to the still well is installed to prevent backflow from high tides. CENTRAL LIFT STATION: A 100 -foot shoreline buffer adjacent to the Duwamish River is built with a clay liner. A French drain installed along the eastern portion of the buffer collects excess stormwater from the buffer and is routed to CB#45. The central lift station is a duplex pump system capable of pumping 46 gpm (single pump) and 92 gpm (dual pump). The lift station discharges water through a 3 -inch force main routed to CB#1. SOUTH LIFT STATION: The south treatment system is located on the southwest portion of the property. Water from the south conveyance system enters CB#44 and is routed into a Contech Vortex() separator vault where coarse solids and oil is trapped. Water then gravity flows into the south lift station. The south lift station is a duplex pump system capable of pumping 150 gpm (single pump) and 300 gpm (dual pump). Water is pumped into a Contech StormFilter® with 40 ZPG cartridges capable of treating up to 300 gpm. Treated water discharges to a manhole to the north where the outlet to the Duwamish River is located. High flow bypass is available through an overflow weir in the Vortex® vault. A duckbill backflow preventor from the high flow bypass pipe is installed in the outlet manhole to prevent backflow during high tides. A flap gate is installed on the outlet pipe from the treatment system in the outlet manhole to prevent backflow into the treatment system from high tides. LIFT STATION CONTROL: All three lift stations are automatically operated by separate SJE Rhombus three-phase duplex lift station control panels. The lift stations are float -switch triggered. In Auto mode, as the water level rises above the STOP float, the panel will remain inactive. As the level rises above the LEAD start float, the lead pump will start and remain ON until the level drops below the STOP level. If the level continues to rise past the start LEAD float and above the start LAG float, the second pump will start and both pumps will remain ON until the level drops below the STOP float. If the level continues to rise, the ALARM float will be activated and trigger a horn and red light at the control panel until the water drops below the level of the ALARM float. Appendix D provides literature on the pumps and controllers of the lift stations.

IMPORTANT: BEFORE PROCEEDING TO INSTALLAND WIRE THE CONTROL PANEL, READAND THOROUGHLY UNDERSTAND THESE INSTRUCTIONS. When installed according to these instructions and Article 504 of the National Electrical Code (NFPA 70) this control panel provides intrinsically safe sensing circuits for interface with Class 1, Division 1, Groups C and D hazardous locations. Intrinsically safe wiring must be in accordance with the enclosed control drawing of the specific intrinsically safe relay manufacturer. NEMA 4X enclosures are for indoor or outdoor use, primarily to provide a degree of protection against corrosion, windblown dust, rain, splashing water and hose -directed water. Cable connectors must be liquid -tight in NEMA 4X enclosures. Installation Most Type 324 panels are designed to operate as three or four float systems. The three float system is standard performing the common pump stop, lead pump start, and lag pump start/high level alarm functions. The four float system utilizes separate floats for lag pump start and high level alarm. NOTE: Options ordered may affect the number of floats and their functions. Please reference the schematic provided with the control panel for proper installation. Installation of Floats CAUTION: If control switch cables are not wired and mounted in the correct location, the pump system will not function properly. 1. Use float label kit to identify and label cables on both float and stripped ends (stop, lead, lag, alarm, etc.). See schematic for float options. 2. Determine your normal operating level, as illustrated in Figures 1-2. 3. Mount float switches at appropriate levels as illustrated in Figures 3-5. Be sure that floats have free range of motion without touching each other, or other equipment in the basin. If using the mounting clamp; follow steps 4-6. 4. Place the cord into the clamp as shown in Figure 5. 5. Locate the clamp at the desired activation level and secure the clamp to the discharge pipe as shown in Figure 5. NOTE: Do not install cord under hose clamp. 6. Tighten the hose clamp using a screwdriver. Over tightening may result in damage to the plastic clamp. Make sure the float cable is not allowed to touch the excess hose clamp band during operation. NOTE: All hose clamp components are made of 18-8 stainless steel material.

The standard float functions are common pump stop, lead pump start, lag pump start/alarrn (three floats), or separate lag and alarm floats (four floats). Other float options, such as redundant off, are available. Three Float Operation: When all floats are in the open or OFF position, the panel is inactive. As the liquid level changes and closes the stop float, the panel will remain inactive until the lead float closes. At this point, the lead pump will start. If the liquid level continues changing and closes the lag/alarm float, the lag pump will start and the audio/visual alarm will activate, Both pumps and the alarm will remain active until the liquid level changes and the lag float opens. At this time the alarm will silence, Both pumps will remain on until the liquid level changes to the normal level and all three floats are opened. When both pumps have stopped running, the alternator will switch the lead pump and lag pump operating functions for the next sequence. Four Float Operation: The alarm will activate and remain on only if the alarm float is closed. Alarm System (Horn and Indicator - standard) When an alarm condition occurs, a red light and a horn will be activated. If the tesUnormal/silence switch is moved to the silence position the horn will be silenced. When the alarm condition is cleared, the horn is reset. The alarm system can be tested by moving the test/normal/silence switch to the test position. Motor Protective Switch A motor protective switch is supplied for each pump to provide an adjustable overload, branch circuit protection and pump disconnect. The overload must be set in the field. To set the overload, dial the amp scale to the pump's full load amps (FLA). If the FLA's are unknown, use a calibrated amp meter to measure the pump amperage draw under loaded conditions. An auxiliary contact is wired in series with the magnetic contactor coil so that on an overload trip, the magnetic contactor will be disabled, .1n. the event of an overload trip, the motor protective switch must be reset by first turning the handle counterclockwise to the OFF position and then turning the handle 90° clockwise to the ON position': Pump Run Lights The run light will be ON in either the hand or the automatic mode when the pump is called to run unless other safety measures are employed. FIGURE 5 - Mounting clamp detail HOA Switch A hand-off-automatie switch is provided for each pump. In the hand mode, the pt.imp will turn on unless other safety features are employed.

Seal Failure Circuit and Indicator Light (optional) The seal fail circuit has resistance sensitivity and will sense the presence of water in the pump seal chamber. Upon installation, turn the sensitivity dial on the seal fill module to the point where the light turns on, then dial back slowly until the light turns off. If water enters the seal chamber at the point, the seal failure circuit will sense the change in resistance. After a short time delay, the indicator light will turn on. When the condition is cleared, the relay will de -energize and the indicator light will turn off. The seal fail relay has a sensitivity adjustment so that false readings may be tuned out. Dry Auxiliary Contacts (optional) Normally open - Contacts are open under normal conditions and closed when alarm condition is present. Normally closed - Contacts are closed under normal conditions and open when alarm condition is present. Both types automatically reset once alarm condition is cleared. Thermal Cutout (optional) The thermal cutout is wired in series with the magnetic contactor coil. If the pump's thermal switch opens on high temperature, the contactor will turn off and stop the pump. When the thermal switch cools and closes, the magnetic contactor will turn on if the pump is called to run. NOTE: Some options ordered may not be included in this manual.

If the light does not activate, replace with same type. Alternating Relay or Device The alternation can be sequenced by lifting the float switches or making jumper wires to simulate the floats closing. If the alterna- tor fails during testing, replace with same type. Consult factory at 1 -800 -RHOMBUS (1-800-746-6287) when in doubt about testing procedures or results. Float Controls Check the floats through their entire range of operation. Clean, adjust, or replace damaged floats. Checking the float resistance - The float resistance can be mea- sured to determine if the float is operating correctly or is defective. Use the following procedure to measure the float resistance: 1. Isolate the float by disconnecting one or both of the float leads from the float terminals. 2. Place one ohmmeter lead on one of the float wires, and the other ohmmeter lead on the other float wire. 3. Place the ohmmeter dial to read ohms and place on the R X 1 scale. With the float in the "off' position, the scale should read infinity (high resistance). Replace the float if you do not get this reading. With the float in the ON position, the scale should read nearly zero (very low resistance). Replace the float if you do not get this reading. NOTE: Readings may vary depending on the length of wire and accuracy of the measuring device. Fuses Check the continuity of the fuse, With power OFF, pull the fuse out of the fuse block. With the ohmmeter on the R X 1 scale, mea- sure resistance. A reading of infinity indicates a blown fuse and must be replaced. Replace fuse with same type, voltage and amp rating. Indicator Lights If defective, replace at indicator pilot lights with same type. Magnetic Contactor Coil Contacts - Check the contacts for severely burnt or welded con- tacts. The contactor arm should move freely. Coil - Measure the coil by disconnecting one of the coil leads. Measure the coil resistance by setting the ohmmeter on the R X 1 scale. A defective coil will read zero or infinity, indicating a short or opened coil respectively. If contactor is defective, replace with same type. NOTE: Readings may vary slightly depending on the accuracy of the measuring device. Motor Protective Switch Test by inserting a paper clip or other small device into the test hole and push to the left. The relay should trip.

The control panel must be situated in a nonhazardous area in an appropriate NEMA rated enclosure, where an explosive atmosphere will not exist at any time. If distance exceeds the length of either the float switch cables or the pump power cables, splicing will be required. For outdoor or wet installation, we recommend the use of a SJE-Rhombus® liquid -tight junction box with liquid -tight connectors to make required connections. Use separate junction boxes for intrinsically safe wiring. WARNING: Intrinsically safe wiring must be kept separate from non -intrinsically safe wiring. Intrinsically safe wiring and non -intrinsically safe wiring may occupy the same raceway if they are at least two inches (50 mm) apart and separately tied down. Inside panels, field wiring terminals for intrinsi- cally safe circuits must be separate from non -intrinsically safe wiring. Do not exceed maximum cable length as stated in intrinsically safe relay control drawing. 2. Mount control panel with mounting flanges furnished. Determine conduit entrance for intrinsically safe wiring, Entrance location must be within intrinsically safe barrier area. A separate rigid metallic conduit must be used to enclose the conductors of the intrinsically safe control circuit. NOTE: Be sure that it is of adequate size to pull the switch cables through. 4. Determine conduit entrance for "power -in" and pump cables. The entrance location must be outside of the intrinsically safe barrier area. NOTE: Be sure the power supply voltage, and phase are the same as the pump motor being installed. If in doubt, see the pump identification plate for voltage/phase requirements. Drill proper size hole for "power -in" and pump cable conduit connections. 6. Attach conduit connectors to control panel, FOR INSTALLATION REQUIRING A SPLICE, FOLLOW STEPS 7-10; FOR INSTALLATION WITHOUTA SPLICE, GO TO STEP 11. see FIGURE 5 for mounting clamp detail FIGURE 1 - Three float duplex (pump down installation) 7. Determine location for mounting junction box according to NEC requirements. Separate junction boxes are required for pump wiring and float wiring. Mount junction boxes to proper supports. Do not mount the junction box inside the sump or basin. 8. Run conduit to junction box. Drill proper size holes for the type of conduit used. Attach connectors to junction box. 9, Identify and label each wire before pulling through conduit into control panel and junction box. Make wire splice connections at junction box. 10. Firmly tighten and seal all fittings on junction boxes. 11, If splicing is not required, identify and label pump cable before pulling through conduit into control panel. 12. Bring intrinsically safe circuits (i.e. float switches) through separate rigid metallic conduit into the control panel area marked for intrinsically safe wiring. WARNING: All wiring entering the hazardous location must be sealed by an approved seal in accordance with the National Electric Code article 504. 13. Wire switch cables according to the schematic provided with control panel. 14. Bring pump cables and "power -in" wiring through conduit into the control panel. 15. Wire the pump cables and the "power -in" cables according to the schematic provided with control panel. 16. Connect "power -in" conductors to proper locations: 208/240/ 480 to three position terminal block. Install tagged factory wire to appropriate transformer primary voltage tap. 17. The GROUND LUG (GL) is a redundant system ground terminal and MUST BE CONNECTED TO THE EARTH GROUND BUSS OF THE CONTROL'S AC SUPPLY LINE FEEDER. The resistance between the system ground terminals and the earth must be less than 1 ohm. Connect ground wire from conduit system to ground terminal (GL) in the panel.

Equipment damage, which occurs by not foliowing f/iese instructions will void the warranty. SAFETY PRECAUTIONS: On/y trained qualified personnel shall boutilized for installation and xtart-up. The following is a general Iist of safety prec11Jt1)ns that should be foUowed when installation starting -up or servicing the pump. The pump station owner or operator is ultimately responsible for ensuring that all eqwpment is instafled, started up and operated in a safe manner. • Do not work alone. * Double check to make sure that aU lifting equipment is in good working order and that it has adequate fti ng capacity for the weight that it will handle. ° Wear safety helmet, goggles and protective shoes, or appropnate safety materiais required. � Before working on the pump make sure that the power is disconnectecl and cannot be energized by others. Lockout and tag the control panel circuit breaker. • Do not stand under suspended loads! • Never enter or work within a wet weIP without irst checking to make sure sufficient oxygen is present and that there are no explosive or poisonous gases present, � All personnel, who work with sewage pumping equipment and systems shafl be vaccinated against diseases that can occur. If there are any questions or doubts in this area it is strongly suggested that the local heatth agency be contacted. • For Hazardous Area Classifications, only use pumps with suitable Explosion Proof Rating. EQUIPMENT INVENTORY AND INSPECTION: Upon arrivat of pump shipmentcarefully unpack all components and compare with shipping and purchase order docurnents to ensure that the order is complete. Also inspect equipment for any damage that might have occurred in shipment. If any problems are cietecfed contact an avthorized HOMA Pump Technology Representative immediately. TRANSPORTATION AND STORAGE PROCEDURE: Always lift the pump by its lifting bail or eye bolt. Never lift the pump by its power cable! Jacketed pump should never stored or shipped with the pump bythe jacket. Damage to Sealing 0 ring may result. Pumps should be stored in an upright position, taking extreme care to protect the power cable and controt cables from crushing, nicks or tears which would permit water intrusion, Power cable ends m ust be protected from immersion in water as well as moisture intrusion. The cable will vvick water into the pump if it is not protected properly. Power cable leads should be covered with shrink tubing or suitable sealing materiat during storage. Short Terni Storage: Short term storage is defined as any time less than six months. We recommend that pump and accessories be stored in its original shipping container in a dry, temperature controlled area. If climate controlled storage is not possible, all exposed parts should bo inspected before storagE arid alt surfaces that have the paint scratched, d.maged 01 worn should be recoated with air dry enamel paint. The pump should be stored in an upright position. Long Term Storage: Any storage time exceeding six months is considered long term. In addition to the safeguards s pecified above, the impeller should be rotated once a month to prevent the mechanical seals from being damaged, and the pum p shou}d be inspected. The seal chamberoil should be drairied and reptaced prior to commissioning. The pum p should be stored in an upright position.

The voltage supphed at the pum p shall be ptus or minus 1O% ofthe nameplate vaiue, frequency shaH be plus or mirius 5% of the nameptate value, the voltage phase balance shaH be within 1% and the maximum corrected powerfactorshall be 1.0, POWER LEAD WIRING HDMAASeries pumps may be provided with 1 or more cables, depending on motor horsepower and operating voltage. Power leads L1.L2.&L3 may be provided as singte conductor, or as multiple conductors. Multiple conductor configurations may use !eads from separate cables, or may use two conductors within one cable. Please refer to wiring diagram in the appendix for specific connection details. The pump mu.st be connected electrically through a motor starter with proper circuit breaker protectfon in order to validate warranty. Do not splice cables. THERMAL SWITCH WIRING : Pumps are equippd with thermal switches embedded in the stator windings which are normally closed, automatically resetting swftches. Switches will open when the internal temperature rises above the design tem perature, and wilt close when the temperature returns to normat. Thermal switches must be wired to a current regulated .control circuit iri accordance with the NEC. Identify thermal switch leads marked T1 and T3 in the power or control cable. The resistance across the leads will be .5 Ohms. Thermal leads must be connected to the therni al overload relay located in the control panel. Thermal switch leads must be connected to validate warranty. Note: All sizes of Class 1, Div. 1 pumps for hazardous service must have thermal switch Ieads connected to a current regulated coritrol circuit in accordance with NEC' SEAL PROBE WIRING The mechanic& seal leak detector probe utilized in the pump is a conductive probe which is normally open. Theintrusion ofwater into the eoal charnber completes the electrical circuit. Control panel provisions will sense this circuit u|nxuro, and will provide indication or atcrm functions depending on the panel design. Either single or dual wire systems may be provided. Single wire systems utilize one energizing conductor, and the pump casing and neutral lead as the ground or return portion of the circuit. The dual wire systems utilize two separate conductors for each leg of the circuit. With either system, the seal probe leads must be wired into a control circuit provided in the control panel. This control circuit must energize the probe with a regulated power source, and sense the closed circuit in event of water intrusion. lndication and alarm functions must also be provided in the control circuit. Please see control panel wiring diagram for seal probe connection points. IMPORTANT: For Hazardous Area Classffication Pumps, leak detectar circuit must be in conformance with app/icable NEC code.s and regulations, START / RUN CAPACITORS AND RELAYS: All single phase motor:, require start and run capacdors along with a tart relay to operate, Refer to the wiring diagram in the appendix. Capacitors and relays must be sized for the specific motor. Capacitors are sized based on ideal conditions. The run capacitor may need to be resized to match the available field voltage. Each cap kit shipped is supplied witb a wiring diagram and start up procedure.

The inverter circuit design, horsepower required by pump, motor cooling system, power cable length, operating voltage, and anticipated turndown ratio must be fully evaluated during the design stage of the installation. As a minimum, properly sized load reactors and filters must be installed between the inverter and the pump to protect the pump motor from damaging vciltagct spikes. Warranty coverage will not be provided on any pump motor that is operated with a variable frequency drive, unless the load side of the inverter is properly isolated from the pump. ADDITIONAL PUMP PROTECTIVE DEVICES Several optional pump protection devices are available to protect submersible motors from damage, and may have provided in you pump. Temperature Sensing RTD*: PT100 sensors are available in two critical locations on larger machines, the lower bearings and motor windings. N.C. Circuit - 108 ohm Moisture Sensors: Two styles of moisture sensors are available on HOMA pumps. Moisture Detectors*: These are micro float switches designed to detect small amounts of liquid. These are available in the stator housing of 50hp and larger size pumps. N.C. Circuit - 268 ohm Leakage Detectors*: These Normally Open, single or 2 wire probes are used to detect the presence of water in the pump. Single wire probes use the pump ground to complete circuit. Optional leak detectors can be installed as follows: Stator Chamber installation: Probe placed in bottom of stator housing to detect presence of water in the chamber. Stator or Motor cap installation: Probe used to detect the presence of water only into the stator housing or motor cap terminal board. Closed loop cooling Installation: Probe placed in cooling loop to detect the presence of water in the cooling media (Glycol). HOMA Go Switch or approved equivalent relay is required for sensor operation. MECHANICAL INSTALLATION: PUMPS WITH AUTOCOUPLING SYSTEMS The HOMA Auto -Coupling is a quick removal system used in keeping personnel from having to enter the wet well. The pump mounts on a stationary base and operates completely or partially submerged (minimum 10' over volute) in the pumping media. The HOMA Auto -Coupling kit consists of a base, guide claw flange, upper guide rail bracket, profile seal and base anchor bolts. Refer to dimensional drawing for details. For all A Series pumps, attach the guide claw flange to the pump discharge flange with the fasteners and gaskets included with the auto - coupling kit. Use tightening torque's indicated in the table on pg. 5. Do not over tighten! Install the profile gasket (if not already installed at the factory) into the guide claw with the large diameter fitted into the groove inside the claw. Refer to the diagram included with the auto - coupling kit for proper profitE.:, gasket installation. Install suitable lifting chain of an adequate size and length to perm it proper lowering and raising of the pump. Properly locate the base and with anchor bolts provided fasten to the floor of the pump station.

Place the guide rails (supplied by others), cut to Iength in to the rings ofthe base, The rais will be secured at the top of the pump station with the upper guide bar bracket and to extend down to the surnp floor. Install the upper guide bar bracket as shown in the appendix. For stations exceed/ng 15 feet in depth intermediate guide bar brackets are recornmended. One bracket is recommended for each addit/onal 15 feet of station depth. Check that the guide system is properly installed in the vertica! orientation by using levets and a plumb Iine, FuIIy tighten all anchors and mounting bolts. Connect the station riser piping to the outlet flarige of the base. Before lowering the pump, verify the direction of impeller rotation (refer to start-up section for procedure). Make sure to use iifting equipment that has adequate capacity for the pump that will be handled. Before installing pump, check to be certairi the profile seal (rubber ring) is properly positioned in the guide claw fi ange. Then position pump so the guides on the discharge flange engage the ralis. Slowiy lower the pump along the guide rail. Once the pump reaches its bottom Iocation it will autornatically corinect to the base. It is recommended that the stationary base elbow be v/sib/e beforeJowering the unit. If this is not possible, ensure all debris is removed from wet well. Important: Do not install more than one (1) check vaive into any piping system or problems will occur. INSTALLATION OF PUMPS WITH RING STANDS: The ring stand design allows for a free standing, simple economical nstaUation or to be transportab)e from one installation to another. It is intended to operate completely or partially submerged in the pumpirig Iiquid. Install the ring stand to the unders ide of the volute with the supplied fasteners provided. Apply thread locking compound s uch as blue #242 and tighten the bolt s using the torque table ndicated in the tble. Do not over tighten! Install suitable lifting devise of an adequate Iength to ensure proper lowering and raising capabilities. Lower the pump into the area where it is required. Properly position powercable and chain so they stay above pump and cannot enter the pump suction. INSTALLATION OF PUMPS FOR DRY PIT APPLICATIONS: Foundation and Piping Requirements: General The foliowing recommendations are basic guidelines which are intended to outline basic requirernents in the design of the dry pit station. It is essential that a licensed professional engineer be retained by the owner to design the station and all support struciures. Foundations Foundations may consist of any structure heavy enough to provide permanent rigid support for the pump and inlet elbow stand. Concrete foundations built up from the solid ground are the most commonly used. The concrete floor shall be level. The space required by the inlet stand and the location of the foundation anchor bolts are shown on the outli ne dimension drawing. Foundation bolts are to be embedded in the concrete.

If reducers are utilized they should be of the conical type. If the liquid source level is below the volute horizontal centerline, the reducer must be eccentric and installed with the level side up. If the liquid level is above the pump volute horizontal centerline, either eccentric or concentric reducers may be used. Suction piping should be run as straight as possible. All pipe flange joints s hould be gasketed to prevent air from entering the pipe. High points that may collect vapor are to be avoided. Isolation valves such as gate valve's can be installed in order to facilitate the removal of the pump for maintenance. Any valve installed in the suction line should be installed with the stems horizontal. Discharge Piping A check valve and isolation valve shall be installed in the discharge line. The check valve should be installed between the pump discharge flange and the isolation valve. If pipe increasers are used on the discharge line, they should be placed between the check valve and the pum p. The inlet elbow stand allow s the pump to be installed in a stationary position in a dry pit. Place the inlet stand in position and tighten the anchor nuts. Lower the pump on to the top flange of the inlet stand. DO NOT ALLOW SLACK ON THE LIFTING CABLE UNTIL THE PUMP IS BOLTED DOWN.

It is important this jacket is function properl, or the internal motor components could become damaged. Several cooIin configurations are available depenthrig upon customer preferencence and system requirements. You must know what configuration of cooling system is to be used with the pump prior to installation. In some cases, field test results may indicate a charige of cooling method is required. Consult actory for necessary changes to the pump. Cooling Requirements 1 - Standard Media Cooled — This construction does not require any extemal piping and it is completely self-contained. This design is suitable for the routine collection system application. No pump modifications are required. RequiredHardwane —AutomaUnoirbleodvokm mounted in uvent port cna1/4^or3@^elbow and small block vaive for venting.Alength cf hose routed to the sump should be attached to either air bleed or the block valve outlet. Start Up Requirements — This jacket must be vented at start up. Additional venting may be required after situations where the suction or discharge piping has been removed for maintenance and reinstaHed. Some adverse operating conditions can allow air to become trapped in this jacket. This must be periodically vented off. If thls occurs, it is recommended the small air bleed valve is utilized, 2 -Media Cooled withExte,nu|Fkush-Thio construction roquires an external flow of water, typically Applications which require this option are typically heavy slurry or sludge service often found in the troatment plant. Th[s option routes the externally supplied water into the pumped media. No pump modifications are roquired. Required Hardware — Mounting aregulating vaive, pressure gouge arid automated biock valve belween the water supply and the upper jacket port is required. The supply vaive should be adjusted to allow the supply af water to exceed pump discharge pressure. This assures a positive flow of water into the pump chamber. The biock vaive should be automated to open whonever the pump is operated, StartUnRenuinements—Thinjauko must be vented at start up Additional venling may be required if cooling water supply 15 interrupted. 3'External Fluid Cooled This option requires an external fiow of water like in option 2 above, but is used where dilution ofthe pumped product is not desirable. The supplof water is internally isolated from the puniped media. The water inlet is routed into the jacket's Iowest port and returned out of the highest port. This option does NOT allow water to enler the pumped media and pump must be ordered from factory this way. Required Hardwar— Mounting a regulating valve, pressure gauge and automated biock vaive between the water supply and the upper jacket port is required. The supply vaive should be adjusted to allow for a good supply of water to flow through the jacket. The biock valve should be automated to open whenever the pump is operated. Start Up Requirements — This jacket must be vented at start up. .Additional venting should not be required. Vent Valve Installation HOMA dry pit pumps are supplied with a vaive and filting that must be insta!led and maintained to erisure the proper performance ofthese purnps. The opening for this vaive is Iocated on the base of the motor cap near the mounting screws, The pump is shipped with a plug installed which must be removed prior to start up. This opening is a metric straight thread and requires an adapier inctuded with the vaive and fitting hardware. It is also recommended that a Iength of hose be attached to the vaive and routed back to the sump.

It is recommended that pumps in intermittent operation be inspected twice a year and pumps inoordinuounuporaUonbuinwpeotedevery 1,000 hours. The following is a listing of required inspection ancl marntenance item s. ff any of the probtems described in the foliowing list exists stop operating the pump to avoid damage or personal injury. 1. CABLE ENTRY Make sure that the cable entry flange and strain relief damp are tight. If the cable entry is showing signs of leakage remove cable from omtry, remove grommet, cut a piece of cable off so that the grommet seats on a new portiori of the cable, replace grommet, and reinslall cable assembly, into the top of the motor. Note: Explosion Proof cab/es are sealed with u Factory Mutual Approved potting compound. Please consult facfory for instruction. 2. CABLES Inspect the cable for cuts, scrapes or sharp bends. If the outer jacket is damaged, replace the cable. Splices of the power or control cable within the wet well area are not acceptable. 3. MOTOR INSULATION RESISTANCE Megger the insulation between the phases; and between any phase and ground, Resistance values should begreater than 1Mohm. If abnormal readings are obtained, contact authorized service center immediately. 4. EXTERNAL PARTS ON PUMP Make sure that all screws, botts and nuts are tight. Check the condition of pump Iifting eyes and replace if damaged or worn, Replace any external part that appears worn or damaged. 5. SEAL CHAMBER OIL Note: Use extreme care when removing the seal chamber p/ug, as the chamber may become pressur/zed ifseal failure has occurred, Seal chamber oil should be checked for signs of water intruaion, or other impurities any time the pump is removed from wet well. To check the condition of the oil, remove the oil fill plug. Drain the chamber volume into a transparent container. Visually check sample for impurities or emulsification (oll may appear cream -like if a small amount of water is present). If significant water intrusion has occurred, remove and replace lower mechanical seal. Unless obvious mechanical damage has occurred to the lower seal, it is good practice to replace the upper and lower mechanical seals as a set. Refill seal chamber with fresh oil to the bottom offill plug port (when pump is in vertical position) and replace oil fill plug. 6. IMPELLER Periodically inspect impeUer by turning pump on its side, remove suction strainer nuts and strainer to expose impeller and relocate position of adjusting pate (suction cover) as needed. Replace the impeller if 1 is damaged or worn. SPARE PARTS In orderto obtain spare parts identify the required parts by ooking at the enclosed cross sectional drawing and listing, and contact authorized HOMA PUMP TECHNOLOGY representative with your order. Authentic Homo Pump Technology parts shall be used to maintain warranty. Note: Explosion Proof pumps must boidentified as .such, and fhe pwnp seria/ number must be referenced for proper parts identification. RECOMMENDED TOOLS AND SUPPLIES In addition to ordinary maintenance and lifting devices, ensure that complete set of metric AlIen wrenches, impeller puller, Loctite 242(B|u*)`and Anti -seize compound are on hand.

The castings shall be constructed of class 30 cast iron. The motor housing shall be oil filled to dissipate heat. Air filled motors shall not be considered equal since they do not properly dissipate heat from the motor. All mating parts shall be machined and sealed with Buna-N 0 - rings. All fasteners exposed to the liquid shall be stainless steel. The upper and lower bearing of the motor shall be capable of handling all radial and thrust loads. The pump is protected with a dual seal configuration with an oil cavity between the two seals. A leak sensor is housed in this chamber to detect the presence of water and will activate an alarm at the control panel indicating service is required. Both seals are silicon carbide / silicon carbide with stainless steel housings and springs, however the lower seal is of a two piece design to facilitate service. 4.01 ELECTRICAL POWER CORD The submersible pump shall be supplied with 25, 35, or 50 feet of a multi -conductor cord of type SOOW. The power cord shall be sized for the rated full load amps of the pump in accordance with the National Electric Code. A separate control cord SOOW of equal length will also exit the pump. Both cords are located within a casting configured for 1-1/2" conduit if the application requires. The cords are secured with a rubber seal ring and potted — the individual strands are exposed to the epoxy to prevent any wicking through the conductors. 5.01 MOTORS Single phase motors shall be oil filled, permanent split capacitor, class F insulated, NEMA B design, rated for continuous duty. Three phase motors shall be oil filled, class F insulated NEMA B design, rated for continuous duty. At maximum load the winding temperature shall not exceed 130 degrees C unsubmerged. Since air filled motors are not capable of dissipating heat they shall not be considered equal. Single phase pump motors shall have an integral thermal / current overload switch in the windings for protecting the motor. A capacitor is required and shall be mounted in the control panel. Three phase motors shall have a thermal overload device mounted on the windings which is connected to a motor control relay located in the control panel. 6.01 BEARINGS AND SHAFT Upper and lower ball bearings shall be required. The bearings shall be a single ball / race type bearing. Both bearings shall be permanently lubricated by the oil which fills the motor housing. The motor shaft shall be made of 300 series stainless steel and have a minimum diameter of .625". 7.01 SEALS The pump shall have two shaft seals with an oil chamber between them. A leak detection probe is positioned in the oil chamber and continuously monitors for water that would indicate the lower seal has failed. The lower seal is a two piece design and can be serviced in the field. The upper is a unitized design, both seals are silicon carbide / silicon carbide seal faces with stainless steel housings and springs. All other seals are of an 0 -ring design of Buna —N material. 8.01 IMPELLER The impeller shall be a class 25 cast iron or bronze with pump out vanes on the back shroud to keep debris away from the seal area. It shall be threaded to the motor shaft. 9.01 CONTROLS All XLE50 series pumps require a control panel. Single phase units utilize a Permanent Split Capacitor, PSC, type motor and require a specific run capacitor. Three phase motor are equipped with a thermal overload that must be connected in the control panel to protect against overheating. Control panels must include intrinsically safe float circuits when pumps are installed in hazardous locations. XLE50-P5 R8/2/2016 °Copyright 2016 Liberty Pumps Inc. All rights reserved.

In addition to implementing required BMPs listed herein, property owners must maintain drainage facilities to meet King County Standards, as required by King County Code 9.04.120. BMPs are required by King County Water Quality Code 9.12. Ifthe BMPs included here are not enough to prevent contamination of stormwater, you will be required to take additional measures. Required BMPs Clean and Maintain Stormwater Drainage System • Evaluate the condition of the catch basin by checking the amount of sediment in the bottom of the catch basin (sump). Catch basins must be cleaned out when the solids, trash and debris in the sump reaches one—half of the depth between the bottom of the sump and the bottom of the lowest inflow or outflow pipe connected to the catch basin or is at least 6 inches below this point. • Clean and maintain catch basins annually. Sites with activities generating sediments and other debris will have to inspect and clean out their catch basins more often. Frequent sweeping of paved parking and storage areas will save time and money in maintaining the stormwater drainage system. • Hire a professional drainage contractor to inspect and maintain your stormwater drainage system or clean the system yourself. If there is sediment or other debris in the drainage pipes, then a professional contractor must be hired to flush or jet out the pipes. Confined space entry should only be conducted by individuals trained to do so. For information on confined spaces refer to www.osha.gov/confined-spaces • Soak up small amounts of floating oil with absorbent pads. The pads and nonhazardous sediments can be bagged up and disposed of as solid waste. Up to one cubic yard of nonhazardous solid material may be disposed of as solid waste in your regular garbage. For additional information please call King County Solid Waste Division at 206-477-4466. If you exceed this threshold hire a professional drainage contractor. For information on how to use absorbent pads please watch Seattle Public Utility's video How to Use Your Spill Kit (https://www.youtube.com/watch?v=NeH98Rx7d0E). • All of the solids and stagnant water collected from catch basin sumps must be disposed of properly. None of the sump contents can be flushed into the catch basin outflow pipe. Contractors who perform catch basin clean-out services are required to follow appropriate disposal requirements.

If this maintenance is beyond your ability, contractors are available to complete this work. Label All Storm Drain Inlets on Your Property • Stencil or apply catch basin/storm drain markers adjacent to storm drains to help prevent the improper disposal of pollutants. If the catch basin grate is stamped with warnings against polluting, then additional marking may not be required if there is no evidence of pollutants being dumped or washed into the storm drain. • When painting stencils or installing markers, temporarily block the storm drain inlet so that no pollutants are discharged from labelling activities. • Maintain the legibility of markers and signs. • Contact King County Stormwater Services at 206-477-4811 for a free stencil or catch basin marker. Eliminate Illicit Connections to the Storm Drainage System • Connections to the stormwater drainage system that convey substances other than stormwater are prohibited. • Illicit connections must be removed immediately, permanently plugged or re - plumbed. • If the connection is re -plumbed, the line must discharge to the proper receiver, such as the sanitary sewer, a septic system, an on-site treatment system, or a holding tank for off-site disposal. There are restrictions on what can be disposed of to the sanitary sewer and septic systems. Contact your sewer authority or Public Health - Seattle and King County. • Unknown connections may require additional investigation to determine where all stormwater and non-stormwater discharges go. This may include smoke, dye or chemical testing, or closed-circuit television inspection. Contact King County Stormwater Services at 206-477-4811 for further assistance. Maintain Drainage Facilities • Drainage facilities must meet the standards and requirements set forth in King County's Surface Water Design Manual for continual performance, operation, and maintenance.

Storage of reactive, combustibles or flammable liquids must comply with the King County Fire Code (KCC 17). The local fire district must be consulted for limitations on clearance of roof covers over containers used to store flammable materials. Potential pollutants can include but are not limited to hydrocarbons, metals, nutrients, oil and grease, oxygen demanding substances, PCBs, pH, and other pollutants. BMPs are required by King County Water Quality Code 9.12. If the BMPs included here are not enough to prevent contamination of stormwater, you will be required to take additional measures. Required BMPs • Place tight—fitting lids on all containers. • Enclose or cover the containers. • Raise containers off the ground with a spill containment pallet or similar method to contain the material in the event of a spill or accident. • Place drip pans or absorbent materials under all potential drip and spill locations during filling and unloading of containers. Properly dispose of collected liquids and used absorbent materials. Turn over empty drip pans when not in use or move under cover. • Do not use metal drums for liquid chemicals that are corrosive. • Label all containers with the product name and associated hazards (e.g., flammable, corrosive, toxic or reactive). • Have spill cleanup materials/spill kit located nearby. • Have a spill plan with current contact information. • Train all employees on spill response methods and procedures. Required Routine Maintenance • Sweep and clean the container storage areas as needed. Do not hose down the area to the stormwater drainage system. • Routinely check containers and replace any compromised ones. Check nearby catch basins to ensure nothing spilled into them. Dispose of all spilled liquids properly. • Inspect spill control devices routinely and properly remove and dispose of accumulated oil and debris.

For washing of parking lots, driveways, or other areas where automotive fluid (e.g., oil, gasoline) are present, see activity sheet A-31: Parking Lots, Driveways, and Outside Storage Areas. For washing of docks, wharves, piers, floats, and boat ramps, see activity sheet A-30: Marine Activities. Potential pollutants can include but are not limited to hydrocarbons, metals, nutrients, oil and grease, oxygen demanding substances, pH, sediment, and other pollutants. Best Management Practices (BMPs) are required by King County Water Quality Code (KCC 9.12). If the BMPs included here are not enough to prevent contamination of stormwater, you will be required to take additional measures. Required BMPs • If soaps, detergents, or any other chemicals are used, use a sump pump, wet vacuum or similar device that enables collection of wash water and associated solids so they can be disposed of properly. The wash water must not go to the stormwater drainage system, groundwater, or surface water. This may require temporarily blocking or disconnecting downspouts from the stormwater drainage system in order to prevent illicit discharges. • Wash water runoff does not have to be collected if: o No soaps, detergents, or any other chemical (including pesticides) are used; o Only cold water is used. Heated water cannot be discharged to the stormwater drainage system; and • the wash water can be diverted to a nearby vegetated area to infiltrate into the ground, or • the wash water is filtered through media (e.g., filter fabric) to trap solid materials, prior to entering a stormwater drainage system. The area must be swept prior to washing, in order to remove all fines (e.g., silts and clay) that may otherwise clog or bypass the filtering process. • Oil stains must be removed with absorbent materials prior to washing • Wash water is not allowed to flow off-site. • If the surface being washed has lead or other heavy metal -bearing paint or dust (such as chromium or cadmium), you must use a commercial washing service that will collect, test, and properly dispose of the wash water.

For storage and use of pesticides and fertilizers see activity sheet A-5: Storage and Use of Pesticides and Fertilizers. Potential pollutants can include but are not limited to fecal coliform bacteria, metals, nutrients, oil and grease, oxygen demanding substances, PCBs, and sediment. BMPs are required by King County Water Quality Code (KCC 9.12). If the BMPs included here are not enough to prevent contamination of stormwater, you will be required to take additional measures. Required BMPs — Landscaping and Vegetation Management • Do not dispose of collected vegetation into surface waters or stormwater drainage systems. • Do not blow vegetation or other debris into the stormwater drainage system, sidewalks, or street. Dispose of collected vegetation by recycling or composting. • Use mulch or other erosion control measures when soils are exposed for more than one week during the dry season (May 1 to September 30) or two days during the rainy season (October 1 to April 30). • Ensure sprinkler systems do not "overspray" vegetated areas resulting in the excess water discharging into the stormwater drainage system. • Ensure that plants selected for planting are not on the noxious weed list. Remove, bag, and dispose of class A and B noxious weeds in the garbage immediately. Make reasonable attempts to remove and dispose of class C noxious weeds. Do not compost noxious weeds as it may lead to spreading through seed or fragment if the composting process is not hot enough. • New and expanding golf courses must have a Golf Course Management Plan as described in addressed in the King County Golf Course BMP Manual Required BMPs - Irrigation • Ensure sprinkler systems do not overspray vegetated areas resulting in runoff discharging into surface waters or stormwater drainage systems. Adjust watering times and schedules to ensure that the appropriate amount of water is being used to minimize runoff. Consider factors such as soil structure, grade, time of year, and type of plant material in determining the proper amounts of water for a specific area. • Inspect irrigated areas regularly for signs of erosion and/or discharge. King County Stormwater Services 68 July 2021 Instrument Number: 20230605000873 Document:COV Rec: S330.50 Page -100 of 128 Record Date:6/5/2023 4:14 PM King County, WA Stormwater Pollution Prevention Manual • Do not irrigate plants during or immediately after fertilizer application. The longer the period between fertilizer application and irrigation, the less fertilizer runoff occurs. • Do not irrigate plants during or immediately after pesticide application (unless the pesticide label directs such timing). • Reduce frequency and/or intensity of watering as appropriate for the wet season (October 1 to April 30). Supplemental BMPs - Landscaping and Vegetation Management • Select the right plants for the planting location based on proposed use, available maintenance, soil conditions, sun exposure, water availability, height, sight factors, and space available. • Use native plants in landscaping. Native plants do not require extensive fertilizer or pesticide applications. • Install engineered soil/landscape systems to improve the infiltration and regulation of stormwater in landscaped areas. • Use at least an eight -inch "topsoil" layer with at least 8 percent organic matter to provide a sufficient vegetation -growing medium. o Organic matter is the least water-soluble form of nutrients that can be added to the soil. Composted organic matter generally releases only between 2 and 10 percent of its total nitrogen annually, and this release corresponds closely to the plant growth cycle. Return natural plant debris and mulch to the soil, to continue recycling nutrients indefinitely. • Select the appropriate turfgrass mixture for the climate and soil type. o Certain tall fescues and rye grasses resist insect attack because the symbiotic endophytic fungi found naturally in their tissues repel or kill common leaf and stem -eating lawn insects. ■ The fungus causes no known adverse effects to the host plant or to humans. ■ Tall fescues and rye grass do not repel root -feeding lawn pests such as Crane Fly larvae. ■ Tall fescues and rye grass are toxic to ruminants such as cattle and sheep. o Endophytic grasses are commercially available; use them in areas such as parks or golf courses where grazing does not occur. o Local agricultural or gardening resources such as Washington State University Extension office can offer advice on which types of grass are best suited to the area and soil type. • Adjusting the soil properties of the subject site can assist in selection of desired plant species. Consult a soil restoration specialist for site-specific conditions.

If herbicides are used, refer to activity sheet A-5: Storage and Use of Pesticides and Fertilizers for required BMPs. • Conduct mulch -mowing whenever practicable. • Till a topsoil mix or composted organic material into the soil to create a well -mixed transition layer that encourages deeper root systems and drought -resistant plants. • Apply an annual topdressing application of 3/8" compost. Amending existing landscapes and turf systems by increasing the percent organic matter and depth of topsoil can: o Substantially improve the permeability of the soil. o Increase the disease and drought resistance of the vegetation. o Reduces the demand for fertilizers and pesticides. Disinfect gardening tools after pruning diseased plants to prevent the spread of disease. • Prune trees and shrubs in a manner appropriate for each species. • If specific plants have a high mortality rate, assess the cause, and replace with another more appropriate species. • When working around and below mature trees, follow the most current American National Standards Institute (ANSI) ANSI A300 standards, http://www.tcia.org/TCIA/BUSINESS/ANSI A300 Standards /TCIA/BUSINESS/A3 00 Standards/A300 Standards.aspx7hkey=202ff566-4364-4686-b7c1- 2a365af59669, and International Society of Arboriculture BMPs to the extent practicable (e.g., take care to minimize any damage to tree roots and avoid compaction of soil). • Monitor tree support systems (stakes, guys, etc.). o Repair and adjust as needed to provide support and prevent tree damage. o Remove tree supports after one growing season or maximum of 1 year. o Backfill stake holes after removal. When continued, regular pruning (more than one time during the growing season) is required to maintain visual sight lines for safety or clearance along a walk or drive, consider relocating the plant to a more appropriate location. o Re -seed bare turf areas until the vegetation fully covers the ground surface. Watch for and respond to new occurrences of especially aggressive weeds such as Himalayan blackberry, Japanese knotweed, morning glory, English ivy, and reed canary grass to avoid invasions. Aerate lawns regularly in areas of heavy use where the soil tends to become compacted. Con -duct aeration while the grasses in the lawn are growing most vigorously. Remove layers of thatch greater than 3A -inch deep.

Generally mowing only 1/3 of the grass blade height will prevent stressing the turf. o Mowing is a stress -creating activity for turfgrass. o Grass decreases its productivity when mowed too short and there is less growth of roots and rhizomes. The turf becomes less tolerant of environmental stresses, more dis-ease prone and more reliant on outside means such as pesticides, fertilizers, and irrigation to remain healthy. Supplemental BMPs - Irrigation • Repair broken or leaking sprinkler nozzles as soon as possible. • Water deeply, but infrequently, so that the top 6 to 12 inches of the root zone is moist. Appropriately irrigate lawns based on the species planted, the available water holding capacity of the soil, and the efficiency of the irrigation system. o The depth from which a plant normally extracts water depends on the rooting depth of the plant. Appropriately irrigated lawn grasses normally root in the top 6 to 12 inches of soil; lawns irrigated on a daily basis often root only in the top 1 inch of soil. • Irrigate with the minimum amount of water needed. Never water at rates that exceed the infiltration rate of the soil. • Maintain all irrigation systems so that irrigation water is applied evenly and where it is needed. • Place sprinkler systems appropriately so that water is not being sprayed on impervious surfaces instead of vegetation. • Place irrigation systems to ensure that plants receive water where they need it. For example, do not place irrigation systems downgradient of plant's root zones on hillsides. • Use soaker hoses or spot water with a shower type wand when an irrigation system is not present. o Pulse water to enhance soil absorption, when feasible. o Pre -moisten soil to break surface tension of dry or hydrophobic soils/mulch, followed by several more passes. With this method, each pass increases soil absorption and allows more water to infiltrate prior to runoff. • Add a tree bag or slow-release watering device (e.g., bucket with a perforated bottom) for watering newly installed trees when irrigation system is not present. • Identify trigger mechanisms for drought -stress (e.g., leaf wilt, leaf senescence, etc.) of different species and water immediately after initial signs of stress appear. + Water during drought conditions or more often if necessary, to maintain plant cover. • Adjust irrigation frequency / intensity as appropriate after plant establishment. • Annually inspect irrigation systems to ensure: King County Stormwater Services 71 July 2021 Instrument Number: 20230605000873 Document:COV Rec: S330.50 Page -103 of 128 Record Date:6/5/2023 4:14 PM King County, WA Stormwater Pollution Prevention Manual o That there are no blockages of sprayer nozzles. o Sprayer nozzles are rotating as appropriate. o Sprayer systems are still aligned with the plant locations and root zones. • Consult with the local water utility, King Conservation District, or Cooperative Extension office to help determine optimum irrigation practices. • Do not use chemigation and fertigation in irrigation systems. This will help avoid over application of pesticides and fertilizers.

Best management practices (BMPs) are required by King County Water Quality Code (KCC 9.12). If the BMPs included here are not enough to prevent contamination of stormwater, you will be required to take additional measures. Required BMPs • Remove solids from associated curbs and gutters before flushing water. Use erosion and sediment control BMPs such as those found in the King County Surface Water Design Manual (straw wattles, D.2.1.2.5; and catch basin inlet protection, C.3.9) to collect any solids resulting from flushing activities. • Discharge water to the sanitary sewer if super chlorination or chemical treatment is used as part of flushing. If sanitary sewer is not available, the water may be infiltrated to the ground as long as it: o is dechlorinated to a total residual chlorine concentration of 0.1 ppm or less; o meets water quality standards; o is discharged through a diffuser to prevent erosion; and o does not cross property lines. • Discharging water (chlorinated to any degree or dechlorinated) to a stormwater drainage system requires approval from King County Stormwater Services. The water must be: o dechlorinated to a total residual chlorine concentration of 0.1 ppm or less; o pH adjusted if necessary; and o volumetrically and velocity controlled to prevent resuspension of sediments in the municipal separate storm sewer system. • Do not over apply dechlorination products. This can deplete the dissolved oxygen concentration and reduce the pH in discharge/receiving waters. Dechlorination products can include ascorbic acid/sodium ascorbate, calcium thiosulfate, sodium sulfite tablets, sodium thiosulfate, sodium bisulfite or other alternate dechlorination products. Supplemental BMPs • If possible, design flushing to convey accumulated materials to strategic locations such as a treatment facility, preventing resuspension and overflow of the solids during storm events. • If possible, conduct flushing and tank maintenance activities on non -rainy days and during the time of the year that poses the least risk to aquatic biota.

In addition to implementing required BMPs listed herein, property owners must maintain drainage facilities to meet King County Standards, as required by King County Code 9.04.120. BMPs are required by King County Water Quality Code 9.12. If the BMPs included here are not enough to prevent contamination of stormwater, you will be required to take additional measures. Required BMPs Clean and Maintain Stormwater Drainage System • Evaluate the condition of the catch basin by checking the amount of sediment in the bottom of the catch basin (sump). Catch basins must be cleaned out when the solids, trash and debris in the sump reaches one—half of the depth between the bottom of the sump and the bottom of the lowest inflow or outflow pipe connected to the catch basin or is at least 6 inches below this point. • Clean and maintain catch basins annually. Sites with activities generating sediments and other debris will have to inspect and clean out their catch basins more often. Frequent sweeping of paved parking and storage areas will save time and money in maintaining the stormwater drainage system. Hire a professional drainage contractor to inspect and maintain your stormwater drainage system or clean the system yourself. If there is sediment or other debris in the drainage pipes, then a professional contractor must be hired to flush or jet out the pipes. Confined space entry should only be conducted by individuals trained to do so. For information on confined spaces refer to www.osha.gov/confined-spaces • Soak up small amounts of floating oil with absorbent pads. The pads and nonhazardous sediments can be bagged up and disposed of as solid waste. Up to one cubic yard of nonhazardous solid material may be disposed of as solid waste in your regular garbage. For additional information please call King County Solid Waste Division at 206-477-4466. If you exceed this threshold hire a professional drainage contractor. For information on how to use absorbent pads please watch Seattle Public Utility's video How to Use Your Spill Kit (https://www.youtube.com/watch?v=NeH98Rx7d0E). All of the solids and stagnant water collected from catch basin sumps must be disposed of properly. None of the sump contents can be flushed into the catch basin outflow pipe. Contractors who perform catch basin clean-out services are required to follow appropriate disposal requirements.

If this maintenance is beyond your ability, contractors are available to complete this work. Label All Storm Drain Inlets on Your Property • Stencil or apply catch basin/storm drain markers adjacent to storm drains to help prevent the improper disposal of pollutants. If the catch basin grate is stamped with warnings against polluting, then additional marking may not be required if there is no evidence of pollutants being dumped or washed into the storm drain. • When painting stencils or installing markers, temporarily block the storm drain inlet so that no pollutants are discharged from labelling activities. • Maintain the legibility of markers and signs. o Contact King County Stormwater Services at 206-477-4811 for a free stencil or catch basin marker. Eliminate Illicit Connections to the Storm Drainage System • Connections to the stormwater drainage system that convey substances other than stormwater are prohibited. • Illicit connections must be removed immediately, permanently plugged or re - plumbed. • If the connection is re -plumbed, the line must discharge to the proper receiver, such as the sanitary sewer, a septic system, an on-site treatment system, or a holding tank for off-site disposal. There are restrictions on what can be disposed of to the sanitary sewer and septic systems. Contact your sewer authority or Public Health - Seattle and King County. • Unknown connections may require additional investigation to determine where all stormwater and non-stormwater discharges go. This may include smoke, dye or chemical testing, or closed-circuit television inspection. Contact King County Stormwater Services at 206-477-4811 for further assistance. Maintain Drainage Facilities • Drainage facilities must meet the standards and requirements set forth in King County's Surface Water Design Manual for continual performance, operation, and maintenance.

Catch basin inserts fit into existing catch basins and are configured to remove one or more of the following contaminants: coarse sediment, oil and grease, and litter and debris. Some units may be able to remove dissolved pollutants and pollutants associated with fine sediments. When selecting an insert, ensure that your specific pollutant -removal needs are met. As with any treatment BMP, catch basin inserts should never be used in place of source control practices. Debris and pollutants drop out TWO PEOPLE LIFTING INSERT Oil and Grease Removal: Inserts designed for the removal of oil and grease contain, and depend on, oil -absorbing media. The King County Surface Water Design Manual (KCSWDM) requires specific materials/media to be used in catch basin inserts to ensure oils are not re- released during storm flows. These inserts are appropriate for use in any area in which vehicles are used, maintained, or stored. Because of the small storage capacity of these inserts, they are not acceptable as the sole line of defense against actual oil spills in areas where large amounts of oil could be released. Large amounts of sediment entering the catch basin significantly reduce the effectiveness and longevity of the oil absorbing media. Under these conditions, an oil/water separator with a pre -settling chamber may be more appropriate. Sediment Removal: Inserts designed for sediment removal may be used at construction sites and in situations where stockpiles or unpaved areas are likely to contribute high sediment loads. They may also be appropriate for small (low traffic) businesses. They are not considered a substitute for other source control BMPs. Debris Removal: Inserts can also be used for the removal of litter and debris, particularly leaf and tree material. Design and Maintenance Unlike most other treatment BMPs, which must be designed and constructed specifically for your site, catch basin inserts may be purchased directly from a vendor and installed by the user. While standardized insert units are available, most vendors are able to customize their systems for your site. Before purchasing a catch basin insert, the following factors must be considered. Conveyance Capacity: The conveyance capacity refers to the amount of water that the insert can pass without causing flooding. This capacity is equal to the amount of water that is able to pass through the insert's treatment area, plus the amount that can pass through King County Stormwater Services 141 July 2021 Instrument Number: 20230605000873 Document:COV Rec: S330.50 Page -112 of 128 Record Date:6/5/2023 4:14 PM King County, WA Stormwater Pollution Prevention Manual the built-in overflow. Over time, the treatment area begins to clog and the total conveyance capacity is reduced. If maintenance is neglected or if an unusually high amount of sediment or debris is captured by the insert, the treatment capacity may drop to zero and all of the water will have to drain through the overflow (routine inspections help prevent this problem). In order to minimize the chance of flooding, the insert should function as designed and be able to handle flow from the area draining to the catch basin. The vendor should be able to tell you what the conveyance capacity is. Don't allow employees to poke holes in the insert to drain flooded areas.

The insert unit should be sized to ensure that most of the water entering the drain inlet is treated even as the treatment area starts to clog. The ability of the insert to remove pollutants will be reduced if water is able to seep between the catch basin grate and the edge of the pavement. Ensure that this gap is sealed. The vendor should provide you with information on how to prevent this situation and information on the treatment capacity of the system. Maximum Weight: The maximum weight of the insert/filter will be equal to the weight of the insert/unit when new, plus the weight of the sediment and water trapped in the unit. Under the most extreme cases, the treatment area of the insert/unit may become King County Stormwater Services 142 July 2021 Instrument Number: 20230605000873 Document:COV Rec: S330.50 Page -113 of 128 Record Date:6/5/2023 4:14 PM King County, WA Stormwater Pollution Prevention Manual completely clogged, and the unit may be full of water when it comes time to service it. It is essential the maximum weight of the insert be less than what can be lifted by the people or equipment to be used during maintenance. Before ordering a system, or having a system customized to your site, be sure the vendor knows how you will be removing the insert/unit for maintenance. Maintenance: Since the installation of one or more catch basin inserts represents a long- term commitment to maintenance, it is important that the unit selected be easy to use and maintain, and that it is built to last. Be sure to have the vendor provide a complete demonstration of the product at your site, and if possible, ask to try an insert before committing to its purchase. Catch basin inserts are ineffective without adequate maintenance. Frequent inspection of the insert is necessary. Actual maintenance will generally consist of removing the insert from the catch basin, emptying accumulated sediments, cleaning or replacing the filter media (if applicable), and reinstalling the insert. In most cases these materials may be disposed of as regular solid waste, however, media used for oil and grease removal may require special treatment. See the Disposal information sheet for more information. Maintenance frequency will vary depending on the site and on the amount and type of pollutant targeted for removal. All units should be inspected every one to two weeks (except during periods of dry weather), and complete maintenance performed whenever necessary. The simplest way to determine whether the units need maintenance is to inspect them during a rainstorm and see whether water is exiting the overflow.

There are generally five options for disposal depending on the types and quantity of materials. These options are: 1. Sanitary sewer system 2. Septic system 3. Municipal solid waste disposal facilities 4. Recycling 5. Off-site waste transportation and disposal services. Ordinary stormwater runoff is not considered to be contaminated, but stormwater that is mixed with concentrated wastes requires special disposal, as discussed below. Discharge to Sanitary Sewer System Wastewater generated by commercial and industrial processes (depending on the nature of the wastewater) may be put into the sanitary sewer, subject to approval by the local sewer authority and the King County Industrial Waste Program. It may be necessary to pretreat the wastewater in order to remove pollutants. Sewer fees may be collected on such discharges. The local sewer authority and King County must be contacted prior to the installation of any permanent connection to the sanitary sewer. Process wastewater may be recycled on-site as an alternative to discharge to the sanitary sewer. There are numerous products on the market that are designed to recycle wash water. It is not an option to discharge stormwater to the sanitary sewer in place of implementing adequate best management practices to prevent contamination. Local Sewer Agency Contact your local sewer agency for information on allowable discharges and the location of your side sewer. The name of your local sewer agency is identified on your water and sewer bill. King County Wastewater Division — Industrial Waste Program The Industrial Waste Program provides information on what can be discharged to the sanitary sewer. Industrial Waste can also assist with information regarding the rerouting of illicit storm water connections/discharges. (206) 263-3000, www.kingcounty.gov/environment/wastewater/IndustrialWaste Discharge to Septic System If your site is not serviced by a sanitary sewer system, you probably have a septic system. Only waste that is comparable to residential sewage may be disposed of into septic systems. Hazardous chemicals and process wastewater cannot be disposed of into septic King County Stormwater Services 153 July 2021 Instrument Number: 20230605000873 Document:COV Rec: S330.50 Page -116 of 128 Record Date:6/5/2023 4:14 PM King County, WA Stormwater Pollution Prevention Manual systems. Furthermore, the septic system must be designed to accommodate the volume of wastewater generated. Any changes in waste volume and constituency from those which existed when the system was permitted must be approved by Public Health — Seattle & King County. Stormwater, whether contaminated or not, may not be disposed of in septic systems. Animal waste may not be disposed of in a septic system unless specifically designed for this purpose.

They do not accept liquid wastes. Hazardous and dangerous wastes and many liquid wastes must be properly transported and disposed of at an appropriate offsite facility. Contact your local solid waste disposal facility or contact King County Solid Waste Division to find out how to dispose of garbage and other materials. King County Solid Waste Division The Solid Waste Division (SWD) provides garbage transfer, disposal and recycling services for residents and businesses in all of King County, except for Seattle and Milton.

There are a number of private businesses that accept materials for recycling. There is also an Industrial Material Exchange clearinghouse which facilitates the transfer of unwanted materials from the generator to another business that can use them.

(206) 263-8465, www.lhwmp.org/home/IMEX/index.aspx Offsite Waste Transportation and Disposal Services Depending on the nature of the waste, it may not be possible to dispose of it in the sewer or municipal landfill. The Seattle -King County Department of Public Health's Waste Characterization Program serves hazardous waste generators in Seattle and King County. Information supplied by the generator on questionable wastes such as sludge, sandblast waste, treated wood, and contaminated soils is reviewed by the Health Department. Permits are issued for wastes that will be allowed in the garbage. The State of Washington's dangerous waste regulations as well as other criteria are used in the decision process. Sumps, holding tanks or other temporary storage devices may be useful for storing relatively small volumes of liquid wastes on a temporary basis if you cannot discharge to a sanitary sewer or septic system. There are commercial services that can help you identify, quantify, transport, and dispose of any waste that you may generate. They can pump out your sump or holding tank and haul the waste to authorized disposal locations. These can be found in the yellow pages under the headings "Sewer Contractors and Cleaners" and "Tank Cleaning," or on the King County Stormwater Services website at www.kingcounty.gov/stormwater. Holding tanks must be pumped out or drained before the tank is full. Septic system pump out and hauling contractors may only dispose of domestic sewage and cannot haul industrial wastes. Costs of disposal vary considerably depending on the types of materials, quantities, methods of collection and transport, and whether the wastes are mixed. The rate the contractor charges will generally reflect the costs of testing and/or treating waste materials (if necessary) and the subsequent disposal. It is important to keep different types of wastes separated, so that the disposal contractors can take them to the appropriate place without causing inadvertent contamination problems elsewhere, and so that you are not paying too much for disposal of materials that are not contaminated (e.g. regular garbage). It is essential to be familiar with disposal alternatives and the different types of contractors for each disposal option so that all wastes are disposed of properly.

Before agreeing to let a company handle your waste, it is recommended that you check the company's references. All waste collected by the company should be delivered to an authorized site. Transfer of waste to a vendor does not release a generator from legal obligation for disposal to a licensed disposal facility. Generators of wastes to be hauled off-site should keep copies of all transactions, including waste manifests and receipts.

A spill plan identifies the materials of concern and outlines the steps to be taken when responding to a spill. Plans are customized to each site and can be prepared in-house or by consultants. A template for a sample spill plan follows. There are numerous resources and templates for spill prevention and clean-up plans that can be found online. The nature of the business, the type and amount of liquid materials transferred and stored on-site, and the potential for spills will dictate the scope and detail of a spill plan. It is critical that the plan be kept up to date to reflect personnel and procedural changes and to have a regular, ongoing review of the plan by all affected employees. Spill plans should include the following elements: • Identification of materials of concern • Spill prevention methods (if you don't have a site pollution prevention plan) • Likely areas for spill or leaks to occur • Site plan that identifies the locations of liquid material storage and spill control equipment • Spill control techniques • Evacuation procedures (if necessary) • Cleanup procedures • Designated responsible employees • Spill reporting protocols • Emergency contact numbers Even if unsure whether a spill presents a threat to human health, welfare, or the environment, go ahead and report it. This will ensure that you have complied with state and federal spill reporting laws. The sooner the agencies know about an incident, the quicker they can deploy resources and assistance to reduce damage to the environment and protect natural resources.
