IT IS <br />SUGGESTED THAT ALL JOINTS BELOW PIPE INVERTS ARE GROUTED. <br />N 0 T E <br />Stormceptor system cleaning shall meet the following minimum requurements: <br />1. Documented inspection of Stormceptor system shall be performed quarterly with annual cleonout and maintenance. <br />2. Inspections should be available to provide to the municipality within 48 hours of request. <br />3. Inspection and maintenance records shall be kept for a minimum of 10 years. <br />4. Both liquid and solid cleonout materials from the Stormceptor system are not permitted to be discharged into <br />municipal storm or combined sewer. Cleanout materials must be removed by vacuum truck and disposed of at the <br />South Bend Wastewater Treatment Plant. <br />Adjustment of the Stormceptor can be performed by lifting the upper sections free of the excavated area, re -leveling the base and re- <br />installing the sections. Damaged sections and gaskets should be repaired or replaced as necessary. Once the Stormceptor has been <br />constructed, any lift holes must be plugged with mortar. <br />12. Maintenance <br />12.1. Health and Safety <br />The Stormceptor System has been designed considering safety first. It is recommended that confined space entry protocols be followed if <br />entry to the unit is required. In addition, the fiberglass insert has the following health and safety features: <br />• Designed to withstand the weight of personnel <br />• A safety grate is located over the 24 inch (600 mm) riser pipe opening <br />• Ladder rungs can be provided for entry into the unit, if required <br />12.2. Maintenance Procedures <br />Maintenance of the Stormceptor system is performed using vacuum trucks. No entry into the unit is required for maintenance (in most <br />cases). The vacuum service industry is a well- established sector of the service industry that cleans underground tanks, sewers and catch <br />basins. Costs to clean a Stormceptor will vary based on the size of unit and transportation distances. <br />The need for maintenance can be determined easily by inspecting the unit from the surface. The depth of oil in the unit can be determined <br />by inserting a dipstick in the oil inspection/cleanout port. <br />Similarly, the depth of sediment can be measured from the surface without entry into the Stormceptor via a dipstick tube equipped with <br />a ball valve. This tube would be inserted through the riser pipe. Maintenance should be performed once the sediment depth exceeds the <br />guideline values provided in the Table 4. <br />Table 4.

Alternatively oil could be removed <br />from the 24 inches (600 mm) opening if water is removed from the lower chamber to lower the oil level below the drop pipes. <br />The following procedures should be taken when cleaning out Stormceptor: <br />1. Check for oil through the oil cleanout port <br />2. Remove any oil separately using a small portable pump <br />3. Decant the water from the unit to the sanitary sewer, if permitted by the local regulating authority, or into a separate containment tank <br />4. Remove the sludge from the bottom of the unit using the vacuum truck <br />5. Re -fill Stormceptor with water where required by the local jurisdiction <br />Stormceptor" Operation and Maintenance Guide 19 <br />12.3. Submerged Stormceptor <br />Careful attention should be paid to maintenance of the Submerged Stormceptor System. In cases where the storm drain system is <br />submerged, there is a requirement to plug both the inlet and outlet pipes to economically clean out the unit. <br />12.4. Hydrocarbon Spills <br />The Stormceptor is often installed in areas where the potential for spills is great. The Stormceptor System should be cleaned immediately <br />after a spill occurs by a licensed liquid waste hauler. <br />12.5. Disposal <br />Requirements for the disposal of material from the Stormceptor System are similar to that of any other stormwater Best Management <br />Practice (BMP) where permitted. Disposal options for the sediment may range from disposal in a sanitary trunk sewer upstream of a sewage <br />treatment plant, to disposal in a sanitary landfill site. Petroleum waste products collected in the Stormceptor (free oiVchemicavfuel spills) <br />should be removed by a licensed waste management company. <br />12.6. Oil Sheens <br />With a steady influx of water with high concentrations of oil, a sheen may be noticeable at the Stormceptor outlet. This may occur because a <br />rainbow or sheen can be seen at very small oil concentrations (<10 mg/L). Stormceptor will remove over 98% of all free oil spills from storm <br />sewer systems for dry weather or frequently occurring runoff events. <br />The appearance of a sheen at the outlet with high influent oil concentrations does not mean the unit is not working to this level of removal. <br />In addition, if the influent oil is emulsified the Stormceptor will not be able to remove it. The Stormceptor is designed for free oil removal <br />and not emulsified conditions. <br />SUPPORT <br />Drawings and specifications are available at www.ContechES.com. <br />Site -specific design support is available from our engineers. <br />@2020 Contech Engineered Solutions LLC, a QUIKRETE Company <br />Contech Engineered Solutions LLC provides site solutions for the civil engineering industry.
