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 Carmel Clay Library. 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, Carmel Clay Library will perform annual compliance inspections of all permanent BMPs. 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 Carmel Clay Library: 10/07/20 -2- Carmel Clay Library Renovation May 2020 · Aqua-Swirl XC-7 · 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 west of the Library and restricts water discharge before releasing to the storm sewer system in the Morrow-Follett legal drain. · Native Vegetated Swales: Vegetated swales are shallow vegetated channels to convey stormwater where pollutants are removed by filtration through grass and infiltration through soil. They look similar to, but are wider than a ditch that is sized only to transport flow. These are located west of the proposed parking garage and drains to the detention pond. 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 Carmel Clay Library. 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 10/07/20 -3- Carmel Clay Library Renovation May 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 Carmel Clay Library. 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. Carmel Clay Library 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: 10/07/20 -4- Carmel Clay Library Renovation May 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. 10/07/20 APPENDIX A SAMPLE INSPECTION LOGS 10/07/20 Post-Construction BMP Inspection Checklist Vegetated Swale Stormwater Ordinance Technical Standards Veg.

Clean air filters, new fuel, oil & filter change, perhaps tune-up, etc. · Check on supplies of materials such as fertilizer, herbicide, garden equipment, etc. March/April/May · Cut down and remove dead leaves, stems and seed heads from perennials and grasses. · Mulch where needed to reduce weeding and maintain moisture. · Plant trees, shrubs, vines, perennials and grasses through May. Recycle all plastic pots. · Prune winter-damaged branches on shrubs or trees that have not begun to grow by late April/early May. · In late April and early May cut back tall grasses by 50% to promote fuller and more compact growth. · Water new transplants and newly planted shrubs and trees unless rainfall is abundant. June/July/August · Vigorous, unwanted limbs should be removed or shortened on new trees. · Cultivate and mulch. Mulching will reduce about 70% of the summer yard maintenance. · Remove diseased plant material by digging entire plant and disposing in trash. Composting will spread the virus. · Water all key planting areas thoroughly unless rainfall has been adequate. · Trim back any groundcover overhanging curbs or sidewalks. September/October · Check plants for signs of water stress, nutrient deficiency or disease. Fertilize only when necessary. · Mulch where needed to reduce weeding and maintain moisture and protect from winter freezing and drought. · September and October are best months to kill invasive species. Cut and spray stumps with 10% glyphosate. Properly dispose of cuttings if they contain berries to prevent spreading the seeds and reinfesting the newly cleared area. · Trim back any groundcover overhanging curbs or sidewalks. November/December · Continue to seek out and remove invasive species. · Clean tree leaves and debris out gutters after tree leaves have fallen. · Winterize hoses and outside water sources. Clean out rain barrels. Add fuel stabilizer to engines before winter storage. Drain and store water hoses. Clean up all tools. · Review the year’s schedule and make plans for next year’s improvements. 10/07/20 APPENDIX D AQUA SWIRL MANUFACTURERS RECOMMENDATIONS 10/07/20 © AquaShieldTM, Inc. 2019.

All rights reserved. Version_0419 Floatable trash & debris in the Aqua-Swirl ® Aqua-Swirl® XCelerator Stormwater Treatment System The Aqua-Swirl® XCelerator Stormwater Treatment System (Aqua-Swirl® XCelerator) is a vortex-type hydrodynamic separator designed and supplied by AquaShieldTM, Inc. (AquaShieldTM). Aqua-Swirl® XCelerator technology removes pollutants including suspended solids, debris, and floatables from stormwater runoff. Both treatment and storage are accomplished in the single swirl chamber without the use of multiple or hidden, blind access chambers. System Operation The treatment operation begins when stormwater enters the Aqua-Swirl® XCelerator 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® XCelerator 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. 10/07/20 © AquaShieldTM, Inc. 2019. All rights reserved. Version_0419 Aqua-Swirl® XCelerator 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® XCelerator 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. Inspection The Aqua-Swirl® XCelerator can be inspected from the surface, eliminating the need to enter the system to determine when cleanout should be performed. In most cases, AquaShieldTM recommends a quarterly inspection during construction and for the first year of operation to develop an appropriate schedule of maintenance. The Aqua-Swirl® XCelerator should be inspected and cleaned at the end of construction regardless of whether it has reached its sediment storage capacity and/or other captured materials. 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 once per year. Maintenance The Aqua-Swirl® XCelerator 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 floatable debris can be directly observed and maintained through the manhole access provided directly over the swirl chamber. Inspection Procedure To inspect the Aqua-Swirl® XCelerator, 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.

The only tools needed to inspect the Aqua-Swirl® XCelerator system are a flashlight and a measuring device such as a stadia rod or pole. Given the easy and direct accessibility provided, floating trash 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. AquaShieldTM recommends that the units be cleaned when sediment depth reaches 6 inches, representing 50% sediment storage capacity. The full sediment storage depth in the Aqua-Swirl® XCelerator is 12 inches. 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. Aqua-Swirl® XCelerator Cleanout Procedure Cleaning the Aqua-Swirl® XCelerator is simple and quick. Floatable trash 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 Aqua-Swirl® XCelerator 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® XCelerator there are no restrictions to impede on-site maintenance tasks. 8” 10/07/20 © AquaShieldTM, Inc. 2019.

Version_0419 Aqua-Swirl® XCelerator Inspection and Maintenance Manual 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 and Debris 1. Remove manhole lid to expose liquid surface of the Aqua-Swirl® XCelerator. 2. Remove floatable debris with basket or net if any present. 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 12 inches for all models. Consult system shop drawing for treatment chamber depth as measured from the inlet pipe invert to base of the unit. 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. 10/07/20 © AquaShieldTM, Inc. 2019. All rights reserved. Version_0419 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, trash, 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® XCelerator. 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® XCelerator 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® XCelerator every three (3) months and clean the system as needed. The Aqua-Swirl® XCelerator 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 unit(s) 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 or floatable pollutant storage capacity. III. Second and Subsequent Years Post-Construction If the system did not reach full sediment or floatable pollutant capacity in the First Year Post-Construction period, the system can be inspected and cleaned once annually. If the Aqua-Swirl® XCelerator reached full sediment or floatable pollutant capacity in less than 12 months in the First Year Post-Construction period, the system should be inspected once every six (6) months and cleaned as needed. The unit should be cleaned annually regardless of whether it reaches its sediment or floatable pollutant capacity. IV. Bypass Structures Bypass structures should be inspected whenever the Aqua-Swirl® XCelerator is inspected. Maintenance should be performed on bypass structures as needed. 10/07/20 © AquaShieldTM, Inc. 2019. All rights reserved.
