Meridian Street, Suite 1100 Indianapolis, IN 46204 Prepared by: Kimley-Horn and Associates, Inc. 250 East 96th Street, Suite 580 Indianapolis, Indiana 46240 Contact: Connor Strege, PE I affirm, under penalties for perjury, that I have taken reasonable care to redact each Social Security number in this document, unless required by law. – Connor Strege Prepared on: May 15, 2023 Revised on: June 22, 2023 Water Quality BMPs Water Quality Best Management Practices (BMPs) are vegetative, structural, and other measures that reduce or eliminate pollutants that might otherwise be carried by surface runoff. Potential pollutant sources include litter form patrons and automobile fluids on the pavement including heavy metals, oil, grease, and alcohols. The stormwater for the site drains via sheet flow to a proposed storm network that discharges into a proposed underground detention system prior to releasing into an offsite wet pond to the east of Lowe’s Way. The vegetated basin allows pollutants and sediment to settle out prior to stormwater leaving the detention area. BMPs for BJ’s Wholesale Club at Greyhound Commons will include: Hydrodynamic Separators (Aqua-Swirl XC-9, XC-5, & XC-2) Filter System (Aqua-Filter AF-XC.2) Underground Detention with Isolator Row (ADS StormTech System - 115,008 cubic feet of storage provided) See Attachment A for a BMP Location Map for this project. BMP Owner Contact Information and Billing Contact Name: Kite Realty Group Contact: Tony Halsey Address: 30 S. Meridian Street, Suite 1100, Indianapolis, Indiana 46204 Business Phone Number: (317) 577-5600 Party Responsible The BMP owner agrees to pay all the fees required by the City of Carmel, including annual inspection fees, and/or any additional fees required. Routine inspections are the responsibility of the BMP owner. Maintenance is also the responsibility of the owner. The City of Carmel must be notified of any changes in BMP ownership, major repairs, or BMP failures in writing within 30 days. The letter should be addressed to: Storm Water Program Carmel Engineering Dept. One Civic Square Carmel, IN 46032 In the event that the City of Carmel finds a BMP in need of maintenance or repair, the City of Carmel will notify the BMP owner of the necessary maintenance or repairs and give the BMP Owner a timeframe for completing the maintenance or repairs. If the maintenance or repairs are not completed within the designated timeframe, the City shall perform the repairs or maintenance and bill the BMP Owner the actual cost of the work. Submittal of annual inspection reports to the City of Carmel Engineering are due one year after construction is completed, with subsequent reports due each year within the same month of the initial report, any deficiencies found during the inspections should be addressed, and the BMP owner faces enforcement action from the City if the inspection report is not received within the month it is due, if there are deficiencies which were not included in the report, or if any deficiencies included in the report are not addressed in a timely manner. Material Handling Disposal of waste from maintenance of drainage facilities shall be conducted in accordance with federal, state, and local regulations. Removed sediment must be handled and disposed of in the garbage as solid waste. Water should be disposed of in a sanitary sewer after oils are removed using oil absorbent materials or other mechanical means. Used oil absorbents should be recycled or disposed according to the manufacturer’s instructions. Safety Work inside underground structures requires special OSHA-required confined space equipment and procedures. The most practical option to perform maintenance or repairs is to contract with a sewer- cleaning contractor Storm Structure Maintenance and Inspection Storm structures on site are identified within the construction plans set. Storm structures are set at storm sewer pipe connections. Unless you have OSHA approved training and equipment, never enter a manhole. Inspection and maintenance of all storm structures is required per the table below. Storm Structure Maintenance and Inspection Inspection All inlet castings should be inspected every 6 months and after each major rainfall event. More frequent inspections should be performed in areas where there is higher potential for trash or litter and during the fall when leaves are present on the ground. Check the frame and lid for cracks and wear, such as rocking lids or lids moved by traffic. Storm structures and the surrounding areas should be inspected annually for pollutants such as leaks from dumpsters, minor spills, and oil dumping. Take action to have the pollutant source removed. Cleaning Clean structures when there is a blockage of a water flow path or when sediment depth reaches 10% of the pipe diameter. Cleaning should be performed in a way that ensures removed sediment and water is not discharged back into the storm sewer. Materials Handling Disposal of waste from maintenance of drainage facilities shall be conducted in accordance with federal, state, and local regulations. Removed sediment must be disposed in the garbage as solid waste. Water should be disposed of in a sanitary sewer after oils are removed using oil absorbent materials or other mechanical means. Used oil absorbents should be recycled or disposed according to the manufacturer's instructions. Repairs Repair all security and access features so they are fully functional. This includes locking lids, covers, and ladder rungs. Replace broken parts or lids that rock or are moved by traffic. Storm Sewer Maintenance and Inspection Storm sewer pipes convey stormwater. Pipes are built from many materials and are sometimes perforated to allow stormwater to infiltrate into the ground. Storm pipes are cleaned to remove sediment or blockages when problems are identified. Storm pipes must be clear of obstructions and breaks to prevent localized flooding. Storm sewer maintenance and inspection required per the table below. Storm Sewer Maintenance and Inspection Inspection Pipes are difficult to inspect requiring special equipment and training. Usually, if a problem occurs the owner needs to call a sewer or plumbing contractor to inspect, repair or clean pipelines. Cleaning Clean pipes when sediment depth is greater than 10% of the pipe diameter. When cleaning a pipe, minimize sediment and debris discharges from pipes to the storm sewer. Install downstream debris traps (where applicable) before cleaning and then remove material. Generally, use mechanical methods to remove root obstructions from inside storm sewer pipes. Do not put root-dissolving chemicals in storm sewer pipes. If there is a problem, remove the vegetation over the line. Materials Handling Sediment and debris from pipes should be disposed in the garbage as solid waste. Pick out any rocks first. Repairs Repair or replace pipes when a dent or break closes more than 20 percent of the pipe diameter. Repair or replace pipes damaged by deterioration. Hydrodynamic Structure Inspection and Maintenance Aqua-Filter™ Stormwater Filtration System is a post-construction flow-through water quality device custom designed to remove fine-grained sediment, heavy metals bound to particulate matter and residual oil by utilizing a treatment train approach. AquaFilter™ technology incorporates a hydrodynamic separation chamber (Aqua-Swirl™) for pretreatment and a separate chamber to provide filtration treatment. An Aqua-SwirlTM concentrator is a swirl concentrator that removes pollutants from stormwater. These pollutants include anything that is significantly heavier or lighter than water. Such pollutants include sediment and oil from parking lots, Styrofoam cups and food packaging, cigarette butts, and other debris. The AquaSwirlTM will also remove any heavy metals or nutrients (phosphorous and nitrates) that will bond to the sediment and organic material that the AquaSwirlTM removes. The Aqua-SwirlTM is a one-piece plastic, or Fiberglass Reinforced Plastic (FRP), structure that includes a cast iron frame and cover. The cover of the AquaSwirlTM has the company logo on it to make it easy to find for maintenance. The opening has a 30” diameter to provide easy access for maintenance from grade level. There should never be a need for someone to enter the AquaSwirlTM. It is designed so that inspection and maintenance can be easily conducted from grade level. Because Aqua-SwirlTM’s collect pollutants, they need to be inspected and cleaned periodically. The following Operation & Maintenance (O & M) procedures are the specific responsibilities for the owner. Refer to the Tabular Maintenance Schedule included in Appendix D of this report for maintenance requirements. Underground Detention Underground detention chambers are designed to detain the stormwater before being released through outlet control structures. Equalizer pipes will be utilized to connect the underground detention systems, which will need to be maintained in accordance with the storm sewer maintenance and inspection guide located in Appendix C. These chambers need to be cleaned to remove sediment or blockages when problems are identified. These units must be clear of obstructions and breaks to prevent localized flooding. Storm sewer maintenance and inspection required per the table below. Turf Vegetative Coverage All non-paved areas that are not landscaped shall be vegetated to prevent erosion and sediment buildup in storm sewer facilities onsite or downstream of the project site.

Floatable debris in the Aqua-Swirl® Aqua-Swirl® Stormwater Treatment System The Aqua-Swirl® Stormwater Treatment System (Aqua-Swirl®) is a vortex-type hydrodynamic separator designed and supplied by AquaShieldTM, Inc. (AquaShieldTM). Aqua-Swirl® technology removes pollutants including suspended solids, trash, floatables and free-floating oil from stormwater runoff. Both treatment and storage are accomplished in the single swirl chamber without the use of multiple or hidden, blind access chambers. Aqua-Swirl® System Maintenance The long term performance of any stormwater treatment structure, including manufactured or land based systems, depends on a consistent maintenance plan. Inspection and maintenance functions are simple and easy for the Aqua-Swirl® allowing all inspections to be performed from the surface. It is important that a routine inspection and maintenance program be established for each unit based on: (a) the volume or load of the contaminants of concern, (b) the frequency of releases of contaminants at the facility or location, and (c) the nature of the area being drained. © AquaShieldTM, Inc. 2022. All rights reserved. Example of Aqua-Swirl® manhole cover Inspection The Aqua-Swirl® can be inspected from the surface thereby eliminating the need to enter the system to determine when cleanout should be performed. AquaShieldTM recommends in most cases that a quarterly inspection take place for the first year of operation to develop an appropriate schedule of maintenance. Based on experience of the system’s first year in operation, we recommend that the inspection schedule be revised to reflect the site-specific conditions encountered. The typical inspection schedule for subsequent years is reduced to semi-annual inspection events. Table 1 below lists the available Aqua-Swirl® models as well their inner diameters, oil/debris storage capacities and the sediment storage capacities. Table 1.

All rights reserved. Sediment inspection using a stadia rod Maintenance The Aqua-Swirl® has been designed to minimize and simplify the inspection and maintenance process. The single chamber of the system can be inspected and maintained entirely from the surface thereby eliminating the need for confined space entry. There are no areas of the structure that are blocked from visual inspection or periodic cleaning. Inspection of any free-floating oil and floatable trash can be directly observed and maintained through the manhole access provided directly over the swirl chamber. If so equipped, the trash screen can be exposed once the water is removed from the unit and inspected. Aqua-Swirl® Inspection Procedure To inspect the Aqua-Swirl®, a hook is typically needed to remove the manhole cover. AquaShieldTM provides a customized manhole cover with our distinctive logo to make it easy for maintenance crews to locate the system in the field. We also provide a permanent metal information plate affixed inside the access riser which provides our contact information, the Aqua-Swirl® model size, and serial number. The only tools needed to inspect the Aqua-Swirl® system are a flashlight and a measuring device such as a stadia rod or pole. Given the easy and direct accessibility provided, floating oil and debris can be observed directly from the surface. Sediment depths can easily be determined by lowering a measuring device to the top of the sediment pile and to the surface of the water. It should be noted that in order to avoid underestimating the volume of sediment in the chamber, the measuring device must be carefully lowered to the top of the sediment pile. Keep in mind that the finer sediment at the top of the pile may offer less resistance to the measuring device than the larger particles which typically occur deeper within the sediment pile. The Aqua-Swirl® design allows for the captured sediment to accumulate in a semi-conical fashion as illustrated below. That is, the depth to sediment as measured below the water surface may be less in the center of the swirl chamber; and likewise, may be greater at the edges of the swirl chamber. 42-48” © AquaShieldTM, Inc. 2022. All rights reserved. Maximum recommended sediment depth prior to cleanout is 14 inches for all Aqua-Swirl® models (not to scale) Aqua-Swirl® Cleanout Procedure Cleaning the Aqua-Swirl® is simple and quick. Free-floating oil and floatable trash can be observed and removed directly through the 30-inch service access riser provided. A vacuum truck is typically used to remove the accumulated sediment and debris. An advantage of the Aqua-Swirl® design is that the entire sediment storage area can be reached with a vacuum hose from the surface reaching all the sides. Since there are no multiple or limited (blind) access chambers in the Aqua-Swirl®, there are no restrictions to impede on-site maintenance tasks. If applicable, the trash screen can be reached from the surface and cleaned with a vacuum hose. Disposal of Recovered Materials AquaShieldTM recommends that all maintenance activities be performed in accordance with appropriate health and safety practices for the tasks and equipment being used. AquaShieldTM also recommends that all materials removed from the Aqua-Swirl® and any external bypass structures (divergent and convergent) be handled and disposed of in full accordance with any applicable local and state requirements. 14” © AquaShieldTM, Inc. 2022.

Floatable Trash/Debris and Oil 1. Remove manhole lid to expose liquid surface of the Aqua-Swirl®. 2. Remove floatable trash/debris with basket or net if any present. 3. If oil is present, measure its depth. Clean liquids from system if one half (½) inch or more of oil and/or trash is present. 4. If applicable, clean trash screen surface with vacuum hose. Note: Water in Aqua-Swirl® can appear black and similar to oil due to the dark body of the surrounding structure. Oil may appear darker than water in the system and is usually accompanied by oil stained debris (e.g. Styrofoam, etc.). The depth of oil can be measured with an oil/water interface probe, a stadia rod with water finding paste, a coliwasa, or collect a representative sample with a jar attached to a rod. II. Sediment Accumulation 1. Lower measuring device (e.g. stadia rod) into swirl chamber through service access provided until top of sediment pile is reached. 2. Record distance to top of sediment pile from top of standing water: inches. 3. Maximum recommended sediment depth prior to cleanout is 14 inches for all models. Consult system shop drawing for treatment chamber depth as measured from the inlet pipe invert to base of the unit. © AquaShieldTM, Inc. 2022. All rights reserved. III. Diversion Structures (External Bypass Features) If a diversion (external bypass) configuration is present, it should be inspected as follows: 1. Inspect weir or other bypass feature for structural decay or damage. Weirs are more susceptible to damage than off-set piping and should be checked to confirm that they are not crumbling (concrete or brick) or decaying (steel). 2. Inspect diversion structure and bypass piping for signs of structural damage or blockage from debris or sediment accumulation. 3. When feasible, measure elevations on diversion weir or piping to ensure it is consistent with site plan designs. 4. Inspect downstream (convergence) structure(s) for sign of blockage or structural failure as noted above. CLEANING Schedule cleaning with local vactor company to remove sediment, trash, oil and other floatable pollutants. The captured material generally does not require special treatment or handling for disposal. Site-specific conditions or the presence of known contaminants may necessitate that appropriate actions be taken to clean and dispose of materials captured and retained by the Aqua- Swirl®. All cleaning activities should be performed in accordance with property health and safety procedures. AquaShieldTM always recommends that all materials removed from the Aqua-Swirl® during the maintenance process be handled and disposed in accordance with local and state environmental or other regulatory requirements. MAINTENANCE SCHEDULE I. During Construction Inspect the Aqua-Swirl® full capture device every three (3) months and clean the system as needed.

All rights reserved. Introduction to Aqua-FilterTM Stormwater Treatment System The highest priority of AquaShieldTM, Inc. (AquaShieldTM) is to protect waterways by providing stormwater treatment solutions to businesses across the world. These solutions have a reliable foundation based on over 20 years of water treatment experience. Local regulators, engineers, and contractors have praised the AquaShieldTM systems for their simple design and ease of installation. All the systems are fabricated from high performance, durable and lightweight materials. Contractors prefer the quick and simple installation of our structures that saves them money. The patented Aqua-FilterTM Stormwater Filtration System provides a high level of performance using a “treatment train” approach that includes the following components:  Pretreatment Hydrodynamic Separator Chamber (HDS), which provides a highly effective means for the removal of sediment, floating debris and free-floating oil  Filtration Chamber, which polishes the water and is capable of removing gross contaminants, suspended sediments, waterborne hydrocarbons, heavy metals and total phosphorous. Pretreatment HDS Chamber Filtration Chamber of Aqua-FilterTM system Page 4 of 19 © AquaShieldTM, Inc. 2017. All rights reserved. Aqua-Filter™ Stormwater Filtration System The patented Aqua-FilterTM system utilizes a unique “treatment-train” approach that includes a pretreatment hydrodynamic separator chamber (HDS) followed by a filtration chamber for secondary treatment. A variety of natural filter media are used in order to complete the treatment process by polishing the stormwater prior to discharge. Independent laboratory and field performance verifications have shown that the Aqua-FilterTM system achieves over 80% suspended solids removal efficiency on a net annual basis using perlite filter media. The Aqua-FilterTM Stormwater Filtration System is designed for sites that require advanced treatment of runoff stormwater to meet stringent discharge requirements. Each Aqua-FilterTM system is custom engineered and utilizes a unique approach for pollutant removal. This patented configuration begins with the removal of sediment, debris and free-floating oil by the pretreatment hydrodynamic separator (HDS) chamber, followed by the removal of fine sediments and other waterborne pollutants by the filtration chamber. The system can be designed for new construction projects or be used for retrofit applications. Inspection and maintenance are simplified by providing oversized risers that allow for both examination and cleanout. An ingress/egress ladder is provided for the filtration chamber to better facilitate maintenance. Each Aqua-FilterTM is constructed of high performance, lightweight and durable materials including polymer coated steel (PCS) or high density polyethylene (HDPE) where allowed. These materials eliminate the need for heavy lifting equipment during installation. Third party performance and functionality testing has demonstrated Total Suspended Solids (TSS) removals of greater than 80% on a net annual basis using perlite filter media.

All rights reserved. the Aqua-FilterTM is effective for the removal of other pollutants including petroleum hydrocarbons, total phosphorus and various heavy metals when bound to particulate material. System Operation The Aqua-FilterTM Stormwater Filtration System operates under gravitational and hydrodynamic forces with no moving parts or valves which simplifies the treatment process. The Aqua-FilterTM system is installed to operate in an off-line configuration. AquaShieldTM recommends that local guidelines be confirmed during the site design process to ensure the proper installation rules for an Aqua-FilterTM system. Step 1: Pretreatment by Hydrodynamic Separator (HDS) Chamber Peripheral pretreatment of stormwater is not necessary when using the Aqua-FilterTM. In fact, each Aqua-FilterTM is custom engineered to utilize a unique treatment train approach. Operation begins when stormwater enters the pretreatment HDS chamber through a tangential inlet pipe that produces a circular (swirl or vortex) flow pattern that causes contaminates to settle to the base of the unit. Since stormwater flow is intermittent by nature, the HDS chamber retains water between storm events providing both dynamic and quiescent settling of solids. The dynamic settling occurs during each storm event while the quiescent settling takes place between successive storms. A combination of gravitational and hydrodynamic drag forces encourages the solids to drop out of the flow and migrate to the center of the HDS chamber where velocities are the lowest. The treated flow then exits the pretreatment HDS chamber behind the arched outer baffle. The top of the baffle is sealed across the treatment channel, thereby eliminating floatable pollutants from escaping the system. A vent pipe is extended up the riser to expose the backside of the baffle to atmospheric conditions, preventing a siphon from forming at the bottom of the baffle.

Step 2: Secondary Treatment by Filtration Chamber The filtration chamber in the Aqua-FilterTM is designed to refine and enhance the stormwater quality prior to discharge. As the pretreated water enters the filtration chamber, it is evenly distributed across the filter bed and allowed to permeate by gravity flow through the filter media. A downflow configuration is used for the filtration chamber. The filter media is contained in individual and durable polyproylene mesh containers (bags) positioned in such manner to avoid short circuiting (see Filter Replacement). The natural filter media used for filtration is capable of removing the remaining waterborne pollutants such as fine-grained sediment, oil, total phosphorus, and heavy metals (e.g., copper, lead, zinc). The most commonly used media is coarse perlite to remove suspended sediment from stormwater runoff. Other filter media such as zeolite, granulated activated carbon, leaf compost, bone char and various proprietary media blends are available where allowed to target site- specific pollutant treatment goals and discharge limits. AquaShield™ Product System Maintenance The long term performance of any stormwater treatment structure, including manufactured or land based systems, depends on a consistent maintenance plan. Inspection and maintenance functions are simple and easy for AquaShieldTM Stormwater Treatment Systems allowing all inspections to typically be performed from the surface. It is important that a routine inspection and maintenance program be established for each unit based on: (a) the volume or load of the contaminants of concern, (b) the frequency of releases of contaminants at the facility or location, and (c) the nature of the area being drained. In order to ensure that our systems are being maintained properly, AquaShieldTM offers a maintenance solution to all of our customers. On request, we will arrange to have maintenance performed.

Inspection All AquaShieldTM products can be inspected from the surface, eliminating the need to enter the systems to determine when cleanout should be performed. In most cases, AquaShieldTM recommends a quarterly inspection for the first year of operation to develop an appropriate schedule of maintenance. Based on experience of the system’s first year in operation, we recommend that the inspection schedule be revised to reflect site-specific conditions being encountered. Typically, the inspection schedule for subsequent years is reduced to semi-annual inspection events.

Pretreatment HDS Chamber Maintenance The pretreatment hydrodynamic separator (HDS) chamber has been designed to minimize and simplify the inspection and maintenance process. The open access HDS chamber can be inspected and maintained entirely from the surface thereby eliminating the need for confined space entry. Inspection of any free-floating oil and floatable debris can be directly observed and maintained through the manhole access provided directly over the swirl chamber. HDS Chamber Inspection Procedure To inspect the pretreatment HDS chamber, a hook is needed to remove the manhole cover. AquaShieldTM provides a customized manhole cover with our distinctive logo to make it easy for maintenance crews to locate a system in the field. We also provide a permanent metal information plate affixed inside the access riser which provides our contact information, the model size and serial number. The only tools needed to inspect the HDS chamber are a flashlight and a measuring device such as a stadia rod or pole. Given the easy and direct accessibility provided, floating oil and debris can be observed directly from the surface. Sediment depths can easily be determined by lowering a measuring device to the top of the sediment pile and to the surface of the water. The maintenance trigger for 3.5 foot to 13 foot diameter HDS chambers (HDS-3 through HDS- 13) occurs when the sediment pile is within 42 to 48 inches of the standing water surface. Page 9 of 19 © AquaShieldTM, Inc. 2017. All rights reserved. Maintenance trigger for 3.5 to 13 foot diameter HDS chamber (HDS-3 through HDS-13) occurs when sediment pile is 42-48 inches below water surface. It should be noted that in order to avoid underestimating the volume of sediment in the chamber, the measuring device must be carefully lowered to the top of the sediment pile. Keep in mind that the finer sediment at the top of the pile may offer less resistance to the measuring device than the larger particles which typically occur deeper within the sediment pile. The HDS chamber design allows for the sediment to accumulate in a semi-conical fashion as illustrated above. That is, the depth to sediment as measured below the water surface may be less in the center of the HDS chamber; and likewise, may be greater at the edges of the HDS chamber. So be careful to make measurements from the center of the HDS chamber, not the edges. HDS Chamber Cleanout Procedure Cleaning the pretreatment HDS chamber is simple and quick. Free-floating oil and floatable debris can be observed and removed directly through the 30-inch service access riser provided. A vacuum truck is typically used to remove the accumulated sediment and debris. An advantage of the HDS chamber design is that the entire sediment storage area can be reached with a vacuum hose from the surface (reaching all the sides). Since there are no multiple or limited (hidden or “blind”) chambers in the pretreatment hydrodynamic separator, there are no restrictions to impede on-site maintenance tasks. Disposal of Recovered Materials from HDS Chamber Disposal of recovered material is typically handled in the same fashion as catch basin cleanouts. AquaShieldTM recommends that all maintenance activities be performed in accordance with appropriate health and safety practices for the tasks and equipment being used. AquaShieldTM also recommends that all materials removed from the HDS chamber and any external structures (e.g, bypass features) be handled and disposed in full accordance with any applicable local and state requirements. 42-48” Page 10 of 19 © AquaShieldTM, Inc. 2017.

Filtration Chamber Maintenance The filter media is also easily observed from the surface. Manhole covers are spaced over the entire filtration bed to provide easy access. AquaShieldTM provides a customized manhole cover with our logo to make it easy for maintenance crews to locate a system in the field. An entry riser provides direct access into the filtration chamber with a permanent ladder welded into the downstream section of the filtration chamber for systems larger than the AF-3.48 model. This additional access allows for the vacuuming of any standing water and an unobstructed access to the downstream side of the filter bed. Permanent ladders are welded to the side of the AF-3.48 model. Page 11 of 19 © AquaShieldTM, Inc. 2017. All rights reserved. Spent filter media can often be recycled or sent to a permitted lined landfill. Always check local regulations to ensure proper disposal of spent filter media. Initially, perlite filter media is light tan or white in color. When the media color turns black or dark brown, it has become saturated due to pollutant loading and requires replacement. Call toll free (888) 344-9044 to order replacement filters. Replacement of the filtration media typically requires entry into the filtration chamber by one of a minimum two-member maintenance crew. Confined space entry methods should be followed by the maintenance crew when removing and replacing the filters. The spent filter containers are normally retrieved from the filter chamber by a second crewmember at the surface through the multiple 30-inch risers spaced across the top of the filter bed. In addition, the filter containers can be accessed directly from within the filtration chamber via a vertical removable panel (bulkhead door) at the rear of the filter bed and directly across from the ladder. The AF-3.48 system utilizes a single manhole with a permanent ingress/egress ladder welded to the side. For larger Aqua-FilterTM systems, and in addition to the ladder, one manhole is typically used for every three rows of filter media. Site-specific conditions may dictate manhole spacing along the length of filtration chambers (models larger than AF-3.48). Filter Media Disposal Disposal of recovered material is typically handled in the same fashion as catch basin cleanouts. AquaShieldTM recommends that all maintenance activities be performed in accordance with appropriate health and safety practices for the tasks and equipment being used. AquaShieldTM also recommends that all materials removed from the pretreatment HDS chamber and any external structures (e.g, bypass features) be handled and disposed in full accordance with any applicable local and state requirements. Filter Media Replacement Filter media containers are installed in two layered courses. Aqua-FilterTM systems (except the AF-3.48) utilize rectangular shaped filter containers. The top layer of filter containers are offset by 90 degrees to that of the bottom layer in order to minimize short-circuiting. Instructions and photographs are provided on page 12 showing the procedures to install fresh rectangular filter media containers. The bottom layer is placed on the fiberglass grates end to end. The top layer is Page 12 of 19 © AquaShieldTM, Inc. 2017. All rights reserved. shown as offset from the bottom layer. Cargo netting is used across the top course of the filter containers to secure them in place.

AF-3.48 ingress/egress ladder and wedge-shaped filter containers. Cargo netting also shown. Cargo Netting Installation Cargo netting is used to secure filter containers in place after containers are installed in the appropriate orientation within the filtration chamber. Cargo netting is placed on top of the top course of filter containers and stretched into place using the provided heavy duty cable ties. The netting is cable-tied to anchor blocks and attached to the side walls of the filtration chamber. It is important to install the netting in such a way as to both cover the entire surface area of the containers while stretching netting snuggly to minimize container movement under high flow conditions. Netting installation is complete when all surface area of filter containers are covered with netting and the netting is secured with cable ties to anchor blocks.

I. Floatable Debris and Oil in HDS Chamber 1. Remove manhole lid to expose liquid surface of the HDS chamber. 2. Remove floatable debris with basket or net if any present. 3. If oil is present, measure its depth. Clean liquids from system if one half (½) inch or more oil is present. AquaShieldTM recommends that any oil be removed as soon as feasible. Note: Water in HDS chamber can appear black and similar to oil due to the dark body of the surrounding structure. Oil may appear darker than water in the system and is usually accompanied by oil stained debris (e.g. Styrofoam, etc.). The depth of oil can be measured with an oil/water interface probe, a stadia rod with water finding paste, a coliwasa, groundwater sampling bailer, or an unspecified improvised method. II. Sediment Accumulation in HDS Chamber 1. Lower measuring device (e.g. stadia rod) into HDS chamber through service access provided until top of sediment pile is reached. 2. Record distance to top of sediment pile from top of standing water: inches 3. For HDS chambers 3.5 to 13 feet in diameter (HDS-3 through HDS-13), schedule cleaning if value in Step #2 is 48 to 42 inches or less. Page 15 of 19 © AquaShieldTM, Inc. 2017. All rights reserved. III. Filtration Chamber 1. Remove manhole lid(s) to expose filter media bed and access ingress/egress ladder. At a minimum, one manhole lid will be present to access ladder. Larger filtration chamber sizes typically have one or more manhole lids to access filter media bed (one manhole per three rows of filter media. 2. Enter filtration chamber via ladder or through access riser(s) over filter bed. Note that water may be present at minimal depths in the filtration chamber prior to clean-out during inspection. 3. Remove bulkhead door (gate) at downstream end of filtration chamber and across from ladder (Figure 1). 4. Remove cargo nets and filters through access risers located along filtration chamber length or through ingress/egress ladder manhole. 5. Visually inspect filter media noting color and saturation or contaminants. 6. If (perlite) media is dark brown or black, the media is fully spent and should be replaced (Figure 2). 7. Contact AquaShieldTM for replacement filter media containers at (888) 344-9044, or info@aquashieldinc.com. 8. Schedule cleaning as described below. IV. Diversion Structures (External Bypass Features) Diversion (external bypass) structures should be inspected as follows: 1. Inspect weir or other bypass feature for structural decay or damage. Weirs are more susceptible to damage than off-set piping and should be checked to confirm that they are not crumbling (concrete or brick) or decaying (steel). 2. Inspect diversion structure and bypass piping for signs of structural damage or blockage from debris or sediment accumulation. Figure 1. Removable bulkhead door across from ingress/egress ladder at rear of filtration chamber. Figure 2. Perlite filter media needs replacement. Page 16 of 19 © AquaShieldTM, Inc. 2017. All rights reserved. 3. When feasible, measure elevations on diversion weir or piping to ensure it is consistent with site plan designs. 4. Inspect downstream (convergence) structure(s) for sign of blockage or structural failure as noted above. CLEANING Schedule cleaning with local vactor company or AquaShieldTM to remove sediment, oil and other floatable pollutants. The spent filter containers and captured material generally does not require special treatment or handling for disposal. Site-specific conditions or the presence of known contaminants may necessitate that appropriate actions be taken to clean and dispose of materials captured and retained by the Aqua-FilterTM system. All cleaning activities should be performed in accordance with proper health and safety procedures. AquaShieldTM always recommends that all materials removed from the Aqua-FilterTM system (HDS chamber and filtration chamber) during the maintenance process be handled and disposed in accordance with local and state environmental or other regulatory requirements.
