Through the use of these Best Management Practices, the sediment and pollutant load in stormwater runoff is reduced, and in many cases the quantity of stormwater water runoff generated is also reduced. The use of Best Management Practices also helps to reduce hydrocarbons, trash and debris from entering waterways. OWNER RESPONSIBILITY The BMP Owner shall be responsible for all maintenance and costs associated with the proposed BMPs. In addition, it is the owner’s responsibility to perform and/or pay for inspections and maintenance as recommended below. RIGHT OF ENTRY The City of Carmel representatives have the right to enter the property to inspect and, if required, maintain the BMPs at any time. ANNUAL INSPECTION REPORTS Annual inspection reports shall be submitted to The City of Carmel for each BMP. 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 of Carmel.

SECTION II SITE INFORMATION The site contains 2 Best Management Practices (BMP) for the purpose of sediment removal. The BMP’s are a First Defense Optimum and an Isolator Row for the developed basin. The First Defense and isolator row are located downstream of the storm network system prior to the underground detention system.. See the attached site exhibits for BMP and storm sewer locations. The City of Carmel will require annual inspection reports of the water quality BMPs. 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 nor received within the month it is due, if there are deficiencies which are nor included in the report, of if any deficiencies included in the report are not addressed in a timely manner, the BMP owner faces enforcement action from the City. SECTION III STORM STRUCTURE MAINTENANCE Storm structures are set at storm sewer pipe connections. Unless you have OSHA approved training and equipment, never enter a manhole. Inspection All inlet castings should be inspected monthly and after each rainfall event. More frequent inspections should be performed in areas where there is higher potential for trash or litter (e.g. retail establishments) 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 6”. Cleaning should be performed in a way that ensures removed sediment and water is not discharged back into the storm sewer. Safety Work inside underground structures requires special OSHA-required confined space equipment and procedures. The most practical option may be to contract with a sewer cleaning contractor. 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. SECTION IV CONVEYANCE MAINTENANCE (STORM SEWER) 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. 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 ¼ of pipe diameter, with a maximum sediment depth of 6”. 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. Safety Work inside underground structures requires special OSHA-required confined space equipment and procedures. The most practical option may be to contract with a sewer--cleaning contractor. 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. SECTION V FIRST DEFENSE SYSTEMS The site contains a First Defender Optimum unit located at the downstream end of the storm sewer system prior to the underground detention system. Swirl concentrators are designed to remove sediment, debris, and free oil from entering the sewer system. After construction the swirl concentrator should be inspected every six months and cleaned as needed or once a year regardless of whether it has reached full pollutant storage capacity. Disposal of all sediment, in addition to local requirements, must be in accordance with all federal and state requirements. See the attached O&M Manual for the swirl concentrator for complete details of inspection and cleaning. Inspection Inspect the unit every six months. The inspection should determine sediment depth, accumulation of trash and litter, and the specific maintenance and repairs needed. Annually check for cracks large enough to let soil enter the vault, broken or defective plates and baffles, and crushed or damaged pipes. Cleaning Remove trash and litter from the vault, inlet and piping when present. Remove sediment when it accumulates to the manufacturer’s maximum recommended depth. Cleaning should be performed in a way that ensures removed sediment and water is not discharged back into the storm sewer. Safety Work inside underground structures requires special OSHA-required confined space equipment and procedures 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 any cracked or defective plates or baffles. 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. SECTION VI UNDERGROUND DETENTION SYSTEM The site contains an underground detention system on the southwest side of the proposed building. Underground detention is located under the eastern side of the parking lot. It will be used as a stormwater quality BMP for the area shown on the Utility Plan C400. The system will be comprised of ADS StormTech MC-7200 chambers. Inspection Identify and report pollutant sources to the Owner and the City of Carmel Engineering - Stormwater. Inspect the Stormtech MC-7200 Chambers for oil and other pollutants and remove any pollutants greater in volume than a surface sheen. Structures that contain a sump or elevated bypass manifold are to be inspected to ensure flow is not obstructed from sediment build-up. Cleaning The JetVac process is a sufficient process to clean the underground detention chambers. A fixed floor cleaning nozzle with rear facing nozzle spread of 45 inches or more is preferable. Apply multiple passes of JetVac until backflush water is clean. Vacuum manhole sump as required. Refer to Section X for the manufacturer’s operation and maintenance guide. Material Handling Disposal of waste from maintenance of drainage facilities shall be conducted in accordance with federal, state, and local regulations. SECTION VII ISOLATOR ROWS Underground detention along with the Isolator Row (s) are located under the parking lot of the site. The Isolator Rows are a combination of the MC-7200 underground chambers wrapped with filter fabric. Refer to the attached Utility Exhibit on sheet C400 for locations. Inspection Identify and report pollutant sources to the Owner and the City of Carmel Engineering - Stormwater. Inspect the Isolator Rows for oil and other pollutants and remove any pollutants greater in volume than a surface sheen. Inspection ports are located along the Isolator Rows. Refer to the Utility Exhibit on sheet C400 for locations. Cleaning The JetVac process is a sufficient process to clean the Isolator Row PLUS.

First Defense® by Hydro International Page | 3 Introduction The First Defense® is an enhanced vortex separator that combines an effective and economical stormwater treatment chamber with an integral peak flow bypass. It efficiently removes total suspended solids (TSS), trash and hydrocarbons from stormwater runoff without washing out previously captured pollutants. The First Defense® is available in several model configurations to accommodate a wide range of pipe sizes, peak flows and depth constraints. The two product models described in this guide are the First Defense® High Capacity and the First Defense® Optimum; they are inspected and maintained identically. Operation The First Defense® operates on simple fluid hydraulics. It is self- activating, has no moving parts, no external power requirement and is fabricated with durable non-corrosive components. No manual procedures are required to operate the unit and maintenance is limited to monitoring accumulations of stored pollutants and periodic clean-outs. The First Defense® has been designed to allow for easy and safe access for inspection, monitoring and clean-out procedures. Neither entry into the unit nor removal of the internal components is necessary for maintenance, thus safety concerns related to confined-space- entry are avoided. Pollutant Capture and Retention The internal components of the First Defense® have been designed to optimize pollutant capture. Sediment is captured and retained in the base of the unit, while oil and floatables are stored on the water surface in the inner volume (Fig.1). The pollutant storage volumes are isolated from the built-in bypass chamber to prevent washout during high-flow storm events. The sump of the First Defense® retains a standing water level between storm events. This ensures a quiescent flow regime at the onset of a storm, preventing resuspension and washout of pollutants captured during previous events. Accessories such as oil absorbent pads are available for enhanced oil removal and storage. Due to the separation of the oil and floatable storage volume from the outlet, the potential for washout of stored pollutants between clean-outs is minimized. • Inlet options include surface grate or multiple inlet pipes • Integral high capacity bypass conveys large peak flows without the need for “offline” arrangements using separate junction manholes • Long flow path through the device ensures a long residence time within the treatment chamber, enhancing pollutant settling • Delivered to site pre-assembled and ready for installation Advantages • Stormwater treatment at the point of entry into the drainage line • Sites constrained by space, topography or drainage profiles with limited slope and depth of cover • Retrofit installations where stormwater treatment is placed on or tied into an existing storm drain line • Pretreatment for filters, infiltration and storage Applications Oil Max Oil Storage Depth Sediment StorageSediment Fig.1 Pollutant storage volumes in the First Defense®.

Periodic removal of these captured pollutants is essential to the continuous, long-term functioning of the First Defense®. The First Defense® will capture and retain sediment and oil until the sediment and oil storage volumes are full to capacity. When sediment and oil storage capacities are reached, the First Defense® will no longer be able to store removed sediment and oil. The First Defense® allows for easy and safe inspection, monitoring and clean-out procedures. A commercially or municipally owned sump-vac is used to remove captured sediment and floatables. Access ports are located in the top of the manhole. Maintenance events may include Inspection, Oil & Floatables Removal, and Sediment Removal. Maintenance events do not require entry into the First Defense®, nor do they require the internal components of the First Defense® to be removed. In the case of inspection and floatables removal, a vactor truck is not required. However, a vactor truck is required if the maintenance event is to include oil removal and/or sediment removal. Maintenance Equipment Considerations The internal components of the First Defense® have a centrally located circular shaft through which the sediment storage sump can be accessed with a sump vac hose. The open diameter of this access shaft is 15 inches in diameter (Fig.3). Therefore, the nozzle fitting of any vactor hose used for maintenance should be less than 15 inches in diameter. Determining Your Maintenance Schedule The frequency of clean out is determined in the field after installation. During the first year of operation, the unit should be inspected every six months to determine the rate of sediment and floatables accumulation. A simple probe such as a Sludge-Judge® can be used to determine the level of accumulated solids stored in the sump. This information can be recorded in the maintenance log (see page 9) to establish a routine maintenance schedule. The vactor procedure, including both sediment and oil / flotables removal, for First Defense® typically takes less than 30 minutes and removes a combined water/oil volume of about 765 gallons. Fig.3 The central opening to the sump of the First Defense®is 15 inches in diameter. 15-in Maintenance Access First Defense® Operation and Maintenance Manual Hydro International (Stormwater), 94 Hutchins Drive, Portland ME 04102 Tel: (207) 756-6200 Fax: (207) 756-6212 Web: www.hydro-int.com Inspection Procedures 1. Set up any necessary safety equipment around the access port or grate of the First Defense® as stipulated by local ordinances. Safety equipment should notify passing pedestrian and road traffic that work is being done. 2. Remove the grate or lid to the manhole. 3. Without entering the vessel, look down into the chamber to inspect the inside. Make note of any irregularities. Fig.4 shows the standing water level that should be observed. 4. Without entering the vessel, use the pole with the skimmer net to remove floatables and loose debris from the components and water surface. 5. Using a sediment probe such as a Sludge Judge®, measure the depth of sediment that has collected in the sump of the vessel. 6. On the Maintenance Log (see page 9), record the date, unit location, estimated volume of floatables and gross debris removed, and the depth of sediment measured. Also note any apparent irregularities such as damaged components or blockages. 7. Securely replace the grate or lid. 8. Take down safety equipment. 9. Notify Hydro International of any irregularities noted during inspection. Floatables and Sediment Clean Out Floatables clean out is typically done in conjunction with sediment removal. A commercially or municipally owned sump- vac is used to remove captured sediment and floatables (Fig.4). Floatables and loose debris can also be netted with a skimmer and pole. The access port located at the top of the manhole provides unobstructed access for a vactor hose to be lowered to the base of the sump. Scheduling • Floatables and sump clean out are typically conducted once a year during any season. • Floatables and sump clean out should occur as soon as possible following a spill in the contributing drainage area. Recommended Equipment • Safety Equipment (traffic cones, etc) • Crow bar or other tool to remove grate or lid • Pole with skimmer or net (if only floatables are being removed) • Sediment probe (such as a Sludge Judge®) • Vactor truck (flexible hose recommended) • First Defense® Maintenance Log Fig.4 Floatables are removed with a vactor hose Page | 6 First Defense® Operation and Maintenance Manual Floatables and Sediment Clean Out Procedures 1.
