Improving the quality can mean: decreasing the amount of total suspended solids (as from sediment laden water), lowering the temperature of runoff, removing trash & debris, as well as other improvements. BMP’s are classified as structural or non-structural. Structural BMPs are mechanical units that treat stormwater at a point. Non-structural BMPs are often ‘green infrastructure’ solutions such as filter strips, bio-retention, porous pavement, etc. The treatment for non-structural BMPs typically occurs over a larger area than that of structural BMPs. However, the non-structural BMPs are typically able to be an integrated part of the site landscape and therefore serve more than one purpose – thus often providing more cost efficiency. 3.1 Right of Inspections: After the approval of the stormwater management permit by the City of Carmel and the commencement of construction activities, the City of Carmel has the authority to conduct inspections of the work being done to ensure full compliance with the provisions of this chapter, this document, and the terms and conditions of the approved permit. 3.2 Maintenance Commitment by Owner of BMP: Stormwater quality facilities shall be maintained in good condition, in accordance with the Operation and Maintenance procedures and schedules listed in the Indiana Stormwater Quality Manual or this document, and/or the terms and conditions of the approved stormwater permit and the Carmel City Code, and shall not be subsequently altered, revised, or replaced except in accordance with the approved stormwater permit, or in accordance with approved amendments or revisions in the permit. Checklists must be completed and maintained by the owner. It is required that the Owner submit annual BMP inspection reports to the City of Carmel. Reports may be submitted to: City of Carmel Storm Water Program One Civic Square Carmel, IN 46032 The first BMP inspection 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 inspections, 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 of Carmel. 3.3 Right of Entry: The City of Carmel also has the authority to perform long-term, post-construction inspection of all public or privately owned stormwater quality facilities. The inspections will follow the operation and maintenance procedures included in this document and/or permit application for each specific BMP. The inspection will cover physical conditions, available water quality storage capacity and the operational condition of key facility elements. Noted deficiencies and recommended corrective action will be included in an inspection report. 4.0 BMP Inspection, Monitoring and Maintenance The following BMPs are included in the proposed site: Mechanical BMP Wet Pond See the sheets attached for more information about these BMPs and the required inspection forms. 4.1 Mechanical BMP The following inspection and maintenance procedures should occur on an annual or as needed basis: See proprietary Aquaswirl Inspection and Maintenance Manual, included herein. 4.2 Wet Pond BMP The wet pond BMP is designed to detain and treat the stormwater runoff from the site. The following inspection, monitoring and maintenance schedule was developed to ensure that the BMPs are functioning in accordance with the design parameters. Seasonal Aquatic Management Plan: Refer to Seasonal Aquatic Management Plan within this Manual for detailed aquatic management and aerator maintenance schedules. In addition to the specific seasonal requirements, the following routine inspection, monitoring and maintenance requirements apply to the wet pond BMP. Wet Pond Monthly Inspections: Routine monthly and annual inspections, as well as monitoring of the BMP IS the responsibility of the owner. Sample monthly inspection logs are included in this document and are to be completed and maintained by the owner. The following areas should be inspected on a monthly basis for the first two years after construction of the BMP: Vegetation: Vegetation should cover greater than 85% of the BMP area above the normal pool of water. Vegetation should be healthy. Vegetation species should be consistent with the plans. Document any invasive species and eradicate within one month of discovery. Pollutants: Remove all floatable debris. Remove visible pollution such as oily sheens, discoloration and cloudy or muddy water. Accumulated sediment depth should be documented. When sediment reaches approximately 50% of the water depth, the pond should be dredged to the original design depth so that the BMP may continue to function as designed. There should be no exposed earth areas on the banks. If any exist, it is critical that they be repaired immediately. Note any other areas where erosion exists. Areas of severe erosion or other conditions that may constitute a public hazard should be corrected as soon as possible and prior to the next monthly inspection. Wet Pond Annual Monitoring: Annual monitoring will be performed for three (3) years after construction to document the development of the BMP in accordance with the construction documents. The following information will be collected as part of the annual monitoring: The results of any past maintenance or corrective actions shall be assessed and documented. A letter report shall be issued that includes monitoring forms, photos, a summary of monthly inspections, and recommendations for routine or special maintenance activities. Wet Pond Maintenance: Maintenance responsibilities shall remain in effect for the life of the BMP from the date the construction is completed. If regular inspection and maintenance guidelines are not followed, the BMP may fail to attain water quality objectives set forth in the City of Carmel regulations. Vegetation: Although the BMP is expected to develop into a dynamic ecosystem that will eventually require little or no vegetation maintenance, some vegetation maintenance will be required in the first 2 years following construction in order to give the new vegetation communities a chance to become well established. If the inspection and monitoring indicates the presence of invasive species, measures will need to be taken to prevent these species from establishing themselves at the new BMP. These species should be either physically removed or treated with herbicide by qualified native plant maintenance professional. The pond banks should be mowed to a height of 8”, once per year, either in the early spring or late fall. Physical removal is strongly preferred above the application of herbicide. If herbicide is used, application must be conducted in compliance with federal, state, and local laws and regulations. Vegetation shall be replanted or reseeded when damaged, vandalized or removed in compliance to original planting specifications. Debris: Debris shall be removed from the BMP in order to maintain a functioning and aesthetically pleasing landscape feature. Nuisance Animals: Burrowing mammals should be controlled when present in densities that endanger the integrity of the embankment. Damage caused by their burrowing must be repaired as soon as possible. Any burrowing mammal control effort will need to be carefully planned and executed to avoid negative impacts to adjacent habitats and wildlife. Such measures will be confined to the embankment. Control of burrowing mammals in other areas of the BMP may not be necessary. The vegetation proposed is not expected to be an attractive habitat for geese since they typically prefer open water and mowed vegetation. Inlet and Outlet Pipes: All inlets and outlets shall be inspected and checked for debris and obstructions which may disrupt flow within the BMP. If any pipes are obstructed, they must be cleared as soon as possible. Sediment accumulation should be monitored annually, and sediment accumulating near inlets should be removed using shovels. The basin should be cleaned out after the construction phase is completed, specifically areas near inlets with visible signs of sediment accumulation. 5.0 Inspection and Maintenance Schedule Type Inspection Maintenance Storm Structure Maintenance Monthly and after significant rain events Accumulation 6” of sediment Storm Pipe Maintenance Monthly and after significant rain events Accumulation 6” of sediment Wet Pond Every 6 months When trash and litter are Visibly present Aqua-Swirl Every 6 months As recommended by manufacturer Stormwater Treatment System Inspection and Maintenance Manual AquaShieldTM, Inc. 2733 Kanasita Drive Suite 111 Chattanooga, TN 37343 Toll free (888) 344-9044 Phone: (423) 870-8888 Fax: (423) 826-2112 Email: info@aquashieldinc.com www.aquashieldinc.com June 2022 © AquaShieldTM, Inc. 2022.

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.

Aqua-Swirl® Inspection and Maintenance Work Sheets SITE and OWNER INFORMATION Site Name: Site Location: Date: Time: Inspector Name: Inspector Company: Phone #: Owner Name: Owner Address: Owner Phone #: Emergency Phone #: INSPECTIONS I. 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. The Aqua-Swirl® should be inspected and cleaned at the end of construction regardless of whether it has reached its maintenance trigger. II. First Year Post-Construction Inspect the Aqua-Swirl® every three (3) months and clean the system as needed. Inspect and clean the system once annually regardless of whether it has reached its sediment, trash or floatable pollutant storage capacity. III.
