Owner Name: Tom Wood, Inc. ATTN: John Wood B. Owner Address: 9820 Association Court Indianapolis, IN 46280 C. Business Phone Number: (317) 574-0143 D. E-mail Address: John_Wood@tomwood.com BMPs: Aqua -Swirl XC-7 and StormTech Isolator Rows The Aqua -Swirl XC-7 model (storm drain insert) is located just east of the renovated building in the front parking lot. The StormTech Isolator Rows (which will act as infiltration trenches) are located within the underground detention system. BMP Inspection and Maintenance: Routine inspections are the responsibility of the BMP owner. Maintenance is also the responsibility of the owner. Sediment removal shall be necessary every 6 months to 1 year. The City of Carmel's Engineering Office must be notified of any changes in BMP ownership, major repairs, or BMP failures in writing within 30 days. The letter should be addressed to: City of Carmel Engineering Department One Civic Square, 1st Floor Carmel, IN 46032 In the event that the City of Carmel's Engineering Office finds a BMP in need of maintenance or repair, the City of Carmel's Engineering Office will notify the BMP owner of the necessary maintenance or repairs and give the landowner a timeframe for completing the maintenance or repairs. If the maintenance or repairs are not completed within the designated time frame, the City shall perform the repairs or maintenance and bill the landowner for the actual cost of the work. The City of Carmel's Engineering Office representatives have the right to enter the property to inspect the BMP. 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. 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-7 & StormTech Isolator Rows. The Aqua -Swirl XC-7 model (storm drain insert) is located just east of the renovated building in the front 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.

BMP Maintenance Information 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, AquaShieldTM, Inc. recommends that for the first year of operation, quarterly inspection of the Aqua-FilterTM 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-SwirITM Installed Above Ground =i 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. Figure 2: Aqua-SwirITM Stormwater Treatment System At ua-Swir1T" � Inspection and Cleanout Procedure Clean out of the Aqua-SwirITM 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 4: Vactoring Aqua-Filtefrm System y r"Lill;- Figure 3: Measuring Sediment Build -Up 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.
