II. Site Drawings III. BMP Maintenance Information BMP Purpose and Specific Narrative Urban Stormwater runoff contains many types and forms of pollutants. When compared to stormwater run-off from pre-developed conditions, high concentrations and some contaminates that are not naturally present in surface runoff from undeveloped local lands are found. Runoff from undeveloped watersheds contains sediment particles, oxygen-demanding compounds, nutrients, metals, and other constituents. Once developed, constituent loads increase because surface runoff volumes increase and the sources of many of these pollutants also increase. Supplemental applications of compounds, such as fertilizers, also tend to increase the availability of some pollutants to stormwater runoff. With this in mind, non-coal tar based sealants must be used if needed during the asphalt resurfacing and sealing. Best management practices (BMP’s), both structural and non-structural, can reduce the pollutants in stormwater. More specifically, we are proposing the Aqua-Swirl XC- 4 On-Line and StormTech Isolator Rows. The Aqua-Swirl XC-4 On-Line model (storm drain insert) is located just southeast of the service building addition in the eastern parking lot. The StormTech Isolator Rows (which will act as infiltration trenches) are located within the underground detention system. The Aqua-Swirl and Isolator Rows remove oil and sediment from the stormwater. Inspections Responsibilities: 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 the City of Carmel Stormwater Technical Standards Manual, and the terms and conditions of the approved stormwater permit, 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. Following construction completion, inspection and maintenance of stormwater quality facilities shall be the long-term responsibility of the Owner. The City of Carmel Engineering department and/or the Hamilton County Surveyor’s Office 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 the City of Carmel Stormwater Technical Standards Manual 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. The Owner shall submit an annual BMP Maintenance Report to the 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 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. This report should be submitted to: Carmel Engineering Department Attn: Stormwater Administrator One Civic Square Carmel, IN 46032 Maintenance Responsibilities: Routine Maintenance: The BMP owner will also be required to perform any maintenance specified at the County’s discretion. The following criteria shall be considered the minimum routine maintenance to be performed: 1. See Aqua-Swirl Stormwater Filtration System - Inspection & Maintenance Manual 2. See StormTech’s Isolator Row O&M Manual Remedial Maintenance: Remedial maintenance shall occur whenever deemed necessary either by the BMP owner or the City of Carmel Engineering Department. Statements and Responsibilities The City of Carmel Engineering Department representatives have the right to enter the property and inspect the BMP at their discretion. The BMP owner is responsible for all maintenance and maintenance costs as outlined in Chapter 7 of the City of Carmel Stormwater Technical Standards.

It is important that a routine inspection and maintenance program is established for each unit based on the volume or load of the contaminants of concern, the frequency of releases of contaminants at the facility or location, and the nature of the area being drained. In most cases, AquaShield™, Inc. recommends that for the first year of operation, quarterly inspection of the Aqua-Filter™ be performed in order to develop an appropriate schedule of maintenance for the site (typically, semi-annual or annual cleanout is required in colder climates where street sanding occurs). We have included a sample inspection worksheet and inspection/maintenance log for your use. Figure 1: Seattle, WA – Aqua-Swirl™ Installed Above Ground Figure 2: Aqua-Swirl™ Stormwater Treatment System Based upon experience from the system’s first year in operation, we recommend the inspection schedule be revised to reflect the site-specific conditions encountered. Again, typically the inspection schedule for subsequent years is reduced to semi-annual inspection. Aqua-Swirl™ Inspection and Cleanout Procedure Clean out of the Aqua-Swirl™ is simple. The chamber can be inspected and maintained completely from the surface (see Figure 3). Free-floating oil and floatable debris can be directly observed and removed through the 28” service access provided. Cleanout of accumulated sediment only needs to be performed when the usable sediment storage volume has been occupied. Specifically, when the sediment pile is within 24” of the water surface, the system should be vactored clean (see Figure 4). Sediment depths can easily be determined by lowering a measuring device (i.e. stadia rod) to the top of the sediment pile and to the water’s surface. Figure 3: Measuring Sediment Build-Up Figure 4: Vactoring Aqua-Filter™ System A vactor truck can be used to remove the accumulated sediment and debris. Disposal of the material is typically treated in the same fashion as catch basin cleanouts. The sediment can be recycled as loose fill material, recycled at an asphalt plant or brick kiln, or used as cover for municipal landfills.

The StormTech Isolator Row is a patented technique to inexpensively enhance Total Suspended Solids (TSS) removal and provide easy access for inspection and maintenance. Looking down the Isolator Row from the manhole opening, woven geotextile is shown between the chamber and stone base. 1.2 THE ISOLATOR ROW The Isolator Row is a row of StormTech chambers, either SC-3!0. SC-310-3, SC-740, DC-780, MC-3500 or MC- 4500 models, that is surrounded with filter fabric and con- nected to a closely located manhole for easy access. The fabric-wrapped chambers provide for settling and filtra- tion of sediment as storm water rises in the Isolator Row and ultimately passes through the filter fabric. The open bottom chambers and perforated sidewalls (SC-310, SC- 310-3 and SC-740 models) allow storm water to flow both vertically and horizontally out of the chambers. Sediments are captured in the Isolator Row protecting the storage areas of the adjacent stone and chambers from sediment accumulation. Two different fabrics are used for the Isolator Row. A woven geotextile fabric is placed between the stone and the Isolator Row chambers. The tough geotextile provides a media for storm water filtration and provides a durable surface for maintenance operations. It is also designed to prevent scour of the underlying stone and remain intact during high pressure jetting. A non-woven fabric is placed over the chambers to provide a filter media for flows passing through the perforations in the sidewall of the chamber. The non-woven fabric is not required over the DC-780, MC-3500 or MC-4500 models as these chambers do not have perforated side walls. The Isolator Row is typically designed to capture the "first flush" and offers the versatility to be sized on a vol- ume basis or flow rate basis. An upstream manhole not only provides access to the Isolator Row but typically includes a high flow weir such that storm water flowrates or volumes that exceed the capacity of the Isolator Row overtop the over flow weir and discharge.through a manifold to the other chambers. The Isolator Row may also be part of a treatment train. By treating storm water prior to entry into the chamber system, the service life can be extended and pollutants such as hydrocarbons can be captured. Pre-treatment best management practices can be as simple as deep sump catch basins, oil-water separators or can be inno- vative storm water treatment devices. The design of the treatment train and selection of pretreatment devices by the design engineer is often driven by regulatory requirements. Whether pretreatment is used or not, the Isolator Row is recommended by Storm Tech as an effective means to minimize maintenance requirements and maintenance costs. Note: See the Storm Tech Design Manual for detailed information on designing inlets for a Storm Tech system, including the Isolator Row.

A routine inspection schedule needs to be established for each individual location based upon site specific variables. The type of land use (i.e. industrial, commercial, residential), anticipated pollutant load, per- cent imperviousness, climate, etc. all play a critical role in determining the actual frequency of inspection and maintenance practices. At a minimum, Storm Tech recommends annual inspec- tions. Initially, the Isolator Row should be inspected every 6 months for the first year of operation. For subsequent years, the inspection should be adjusted based upon previous observation of sediment deposition. The Isolator Row incorporates a combination of standard manhole(s) and strategically located inspection ports (as needed). The inspection ports allow for easy access to the system from the surface, eliminating the need to perform a confined space entry for inspection purposes. If upon visual inspection it is found that sediment has accumulated, a stadia rod should be inserted to deter- mine the depth of sediment. When the average depth of sediment exceeds 3 inches throughout the length of the Isolator Row, clean-out should be performed. 2.2 MAINTENANCE The Isolator Row was designed to reduce the cost of periodic maintenance. By "isolating" sediments to just one row, costs are dramatically reduced by eliminating the need to clean out each row of the entire storage bed. If inspection indicates the potential need for main- tenance, access is provided via a manhole(s) located on the end(s) of the row for cleanout. If entry into the manhole is required, please follow local and OSHA rules for a confined space entries.

(These are not Storm Tech products.) Maintenance is accomplished with the JetVac process. The JetVac process utilizes a high pressure water noz- zle to propel itself down the Isolator Row while scouring and suspending sediments. As the nozzle is retrieved, the captured pollutants are flushed back into the man- hole for vacuuming. Most sewer and pipe maintenance companies have vacuum/JetVac combination vehicles. Selection of an appropriate JetVac nozzle will improve maintenance efficiency. Fixed nozzles designed for cul- verts or large diameter pipe cleaning are preferable. Rear facing jets with an effective spread of at least 45" are best. Most JetVac reels have 400 feet of hose allow- ing maintenance of an Isolator Row up to 50 chambers long. The JetVac process shall only be performed on StormTech Isolator Rows that have AASHTO class 1 woven geotextile (as specified by StormTech) over their angular base stone. 2 LAYERS OF AO$ 31(; WOVEN GEOTEXTJLE iOR EQUAL) BETWEEN STONE BASE AND CHAMBERS MC-4500 • 10.J' {3.1 m) WIDE STRIP (ADS 315\oVTM) MC-3500 • 8..25' i2.5 m) WIDE STRIP [ADS 315WTM) SC-740 & OC-780 • 5' {1.5 m) WIDE STRIP (ADS 315WTK) SC·J10 & SC-310-3 • 4' (1.2 rn) WIDE STRIP (ADS 315WTK) NOTE: NON-WOVEN FABRIC IS ONLY REQUIRED OVER THE INLET PIPE CONNECTION INTO THE END CAP FOR DC-780, MC-3500 AND MC-4500 CHAMBER MODELS AND IS NOT REQUIRED OVER THE ENTIRE ISOLATOR ROW.
