In order to maintain water quality within the BMP, light maintenance activities will be needed to manipulate hydrology. This document defines responsibilities for operating, inspecting and maintaining the stormwater system at the Zotec Partners Tech Village. 3.0 STORMWATER & DETENTION MAINTENANCE Storm sewer pipes, detention pond, and outlet control weir structure should be regularly maintained and cleaned of debris. All piping should be inspected monthly and after each rainfall event, especially during the autumn season. Weir plate (STR 200 outlet control structure) should be inspected more regularly when falling leaves are present. Refer to Appendix B for Maintenance Map and Details. Sample inspection logs are included in Appendix D. Disposal of all sediment must be in accordance with all federal, state and local requirements. Additionally, Zotec Partners will perform annual compliance inspections of all permanent BMPs. -2- Zotec Partners Tech Village April 2020 4.0 WATER QUALITY SYSTEM MAINTENANCE The City of Carmel reserves the right to enter the property at any time to inspect the operation of any Best Management Practices (BMP) onsite. The following is a list and description of the three BMPs at the Zotech Partners Tech Village: · Aqua-Swirl AS-7 & AS-5. · Native planted Extended Dry Detention Pond: Vegetated dry detention ponds are depressed basins that temporarily store a portion of stormwater runoff following a storm event. The objective of these systems is to remove particulate pollutants with plantings and to reduce maximum runoff values that typically result from site development. The pond is located at the south end of the property and restricts water discharge before releasing to the storm sewer system in Illinois Street. See Appendix B for the location and details of all infrastructure and water quality BMPs. 4.1 WATER QUALITY DEVICES INSPECTIONS The BMPs require certain items to be inspected on a monthly or annual basis during the existence of the BMPs. This is the responsibility of Zotec Partners. More frequent inspections may need to take place during periods of heavy rainfall. For each drainage system listed below, the following details shall be inspected monthly and after major rainfall events (>1 inch in 24 hours). Also refer to sample inspection logs in Appendix D. · Underdrains– Remove all debris to ensure openings are clear and operating properly. Cleanouts (C.O.) at the end of underdrain pipes should be utilized for debris removal. Water and sediment from cleaning procedures should NOT be dumped into a sanitary sewer. · BMP inlets and outlets (piping) – Remove all debris to ensure openings are clear and operating properly. The maximum sediment depth should be no more than ¼ of the pipe diameter and up to a maximum depth of 6”. Check for rip rap stone displacement and erosion of the apron surrounding pipe end section. Repair immediate failure. Water and sediment from cleaning procedures should NOT be dumped into a sanitary sewer. · BMP native vegetation – This area includes all turf vegetation within the boundary of the BMPs. Some species of plants are considered invasive and should be eradicated. Species such as reed canary grass (Phalaris arundinacea), purple loosestrife (Lythrum salicaria), common reed (Phragmites australis), and cattails (Typha spp.) would be considered fast colonizing and invasive species. Remove as necessary. See desired planting list & schedule in Appendix C. A protective cover of vegetation shall be established on all exposed surfaces of the pond embankment, spillway, borrow and spoil areas and to a minimum of 50 feet on all sides of pond and 100 feet upstream of the pool area. Open areas to be vegetated will be limed, fertilized, seeded and mulched -3- Zotec Partners Tech Village April 2020 according to the construction specification. No woody vegetation shall be planted on or within 25 feet of the pond embankment or spillway. See Appendix B for the location and details of all infrastructure and water quality BMPs. If these maintenance guidelines are not followed, the BMP’s may fail to attain water quality objectives set forth in the regulations. The BMP shall be owned by the developer/property owner; any and all maintenance and repair activities shall be paid for by the owner. Documentation of all repairs should be kept on file by the owner for review by City of Carmel inspectors. Sample inspection logs are included in Appendix D. Right of Entry - The City of Carmel may inspect the premises at any time necessary to determine the functionality of any BMPs onsite. City of Carmel Note- The BMPs shall be owned by the developer/property owner; any and all maintenance and repair activities shall be paid for by Indiana Montessori Academy. The requirements of the O&M Manual shall remain in effect regardless of change in ownership of the development. Furthermore, it shall be the responsibility of the BMP owner to provide the O&M Manual to future parties who will assume responsibility for the operation and maintenance of the post-construction storm water quality measures. Zotec Partners will perform annual compliance inspections of all onsite BMPs and provide the reports to City of Carmel Engineering Department. The first report is due one year after construction is completed, with subsequent reports due each year within the same month of the initial report. If there are any deficiencies found during the inspection, these should be addressed. 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, the BMP owner faces enforcement action from the City. Refer to Agreement in Appendix A. 5.0 SUMMARY The objective of the operation and maintenance manual is to allow the owner of the storm management system to manage the system to the City of Carmel specifications. The City requires minimal information for their records: -4- Zotec Partners Tech Village April 2020 1. Maintenance agreement. The agreement requires the owner to comply with the maintenance set forth in the manual. 2. Monthly and annual data sheets and repair documentation must be kept on site for the City Inspectors to review during their annual inspection of the site.

(AquaShield™) 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 AquaShield™ 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 line of AquaShield™ stormwater treatment products that provide high levels of stormwater treatment include the following: Aqua-Swirl® Stormwater Treatment System: hydrodynamic separator, which provides a highly effective means for the removal of sediment, floating debris and free- oil. Aqua-FilterTM Stormwater Filtration System: treatment train stormwater filtration system capable of removing gross contaminants, fine sediments, waterborne hydrocarbons, heavy metals and total phosphorous. Aqua-Swirl® Stormwater Treatment System Aqua-Filter™ Stormwater Filtration System Page 4 of 15 Aqua-Swirl® Stormwater Treatment System The patented Aqua-Swirl® Stormwater Treatment System is a single chamber hydrodynamic separator which provides a highly effective means for the removal of sediment, free oil, and floating debris. Both treatment and storage are accomplished in the swirl chamber without the use of multiple or “blind” chambers. Independent laboratory and field performance verifications have shown that the Aqua-Swirl® achieves over 80% suspended solids removal efficiency on a net annual basis. The Aqua-Swirl® is most commonly installed in an “off-line” configuration. Or, depending on local regulations, an “in-line” (on-line) conveyance flow diversion (CFD) system can be used. The CFD model allows simple installation by connecting directly to the existing storm conveyance pipe thereby providing full treatment of the “first flush,” while the peak design storm is diverted and channeled through the main conveyance pipe. The patented Aqua-Swirl® Stormwater Treatment System provides a highly effective means for the removal of sediment, floating debris, and free oil. Swirl technology, or vortex separation, is a proven form of treatment utilized in the stormwater industry to accelerate gravitational separation. Page 5 of 15 Floatable debris in the Aqua-Swirl® Each Aqua-Swirl® is constructed of high performance, lightweight and durable materials including polymer coated steel (PCS), high density polyethylene (HDPE), or fiberglass reinforced polymer (FRP). These materials eliminate the need for heavy lifting equipment during installation. System Operation The treatment operation begins when stormwater enters the Aqua-Swirl® through a tangential inlet pipe that produces a circular (or vortex) flow pattern that causes contaminates to settle to the base of the unit. Since stormwater flow is intermittent by nature, the Aqua-Swirl® 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 chamber where velocities are the lowest. The treated flow then exits the Aqua-Swirl® 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. Custom Applications The Aqua-Swirl® system can be modified to fit a variety of purposes in the field, and the angles for inlet and outlet lines can be modified to fit most applications. The photo below demonstrates the flexibility of Aqua-Swirl® installations using a “twin” configuration in order to double the Page 6 of 15 Custom designed AS-9 Twin Aqua-Swirl® water quality treatment capacity. Two Aqua-Swirl® units were placed side by side in order to treat a high volume of water while occupying a small amount of space. Retrofit Applications The Aqua-Swirl® system is designed so that it can easily be used for retrofit applications. With the invert of the inlet and outlet pipe at the same elevation, the Aqua-Swirl® can easily be connected directly to the existing storm conveyance drainage system. Furthermore, because of the lightweight nature and small footprint of the Aqua-Swirl®, existing infrastructure utilities (i.e., wires, poles, trees) would be unaffected by installation. 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 the AquaShieldTM Stormwater Treatment Systems 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. In order to ensure that our systems are being maintained properly, AquaShieldTM offers a maintenance solution to all of our customers. We will arrange to have maintenance performed. Page 7 of 15 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 the site-specific conditions encountered. Typically, the inspection schedule for subsequent years is reduced to semi-annual inspection. Aqua-Swirl® Maintenance The Aqua-Swirl® has been designed to minimize and simplify the inspection and maintenance process. The single chamber system can be inspected and maintained entirely from the surface thereby eliminating the need for confined space entry. Furthermore, the entire structure (specifically, the floor) is accessible for visual inspection from the surface. There are no areas of the structure that are blocked from visual inspection or periodic cleaning. 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. Aqua-Swirl® Inspection Procedure To inspect the Aqua-Swirl®, 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 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. Page 8 of 15 Sediment inspection using a stadia rod in a single chamber Maintain system when sediment is 42-48 inches below water surface. Maximum sediment storage capacity reached when sediment is 30 inches below water surface. 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. When the sediment pile is within 42 to 48 inches of the water surface (or sediment pile thickness is 18 to 24 inches as measured from the base), the system should be maintained. The maximum sediment storage capacity of the Aqua-Swirl® is reached when the sediment pile is within 30 inches of the water surface (or sediment accumulation is 36 inches thick as measured from the base). 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 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 swirl chamber; and likewise, may be greater at the edges of the swirl chamber. Aqua-Swirl® Cleanout Procedure Cleaning the Aqua-Swirl® 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 ” Page 9 of 15 Vacuum truck quickly cleans the Aqua-Swirl® from a single chamber 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 (hidden or “blind”) chambers in the Aqua-Swirl®, there are no restrictions to impede on-site maintenance tasks. Disposal of Recovered Materials 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 Aqua-Swirl® and any external structures (e.g, bypass features) be handled and disposed in full accordance with any applicable local and state requirements.

Floatable Debris and Oil 1. Remove manhole lid to expose liquid surface of the Aqua-Swirl®. 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. 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 (Figure 1). From a reference point at the top of the service access: 2. Record distance to top of sediment pile (Figure 2): inches 3. Record distance to top of water surface: inches 4. Calculate distance to sediment minus distance to water: inches 5. Schedule cleaning if value in Step #4 is 48 to 42 inches or less. The sediment storage capacity is exceeded when the depth to sediment is within 30 inches of the water surface and maintenance should be performed immediately. Page 11 of 15 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 or AquaShieldTM to remove sediment, 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. Figure 2. Maintain system when sediment is 42 to 48 inches below water surface to ensure proper system operation and performance. Maximum sediment storage capacity is reached when sediment is 30 inches below water surface. Figure 1. Measuring sediment in swirl chamber using stadia rod.
