Most storm drain inserts reduce oil and grease, debris, and suspended solids through gravity, centrifugal force, or other methods. BMPs such as these can be particularly useful in areas susceptible to spills of petroleum products, such as gas stations. Figure PC-107A illustrates one of many different types of storm drain inserts. Trapped sediments and floatable oils must be pumped out regularly to maintain the effectiveness of the units. ADVANTAGES 1.Prefabricated for different standard storm drain designs. 2.Require minimal space to install. LIMITATIONS 1.Some devices may be vulnerable to accumulated sediments being resuspended during heavy storms. 2.Can only handle limited amounts of sediment and debris. 3.Maintenance and inspection of storm drain inserts are required before and after each rainfall event. 4.High maintenance costs. 5.Hydraulic losses. DESIGN CRITERIA 1.Calculate the minimum flow rate to be mitigated by the storm drain insert using the methods in Section 701-05. 2.Select unit which meets Ordinance-required TSS removal rate for design flow rate. 3.Provide an overflow to bypass flows greater than the water quality treatment rate.

Outlet Inlet AppendixC MaintenanceandManagementInspection Checklist Inspection TM All AquaShield products can be inspected from the surface, eliminating the need to enter the TM systems to determine when cleanout should be performed. In most cases, AquaShield recommends a quarterly inspection for the first year of operation to develop an appropriate schedule of maintenance. recommend that the inspection schedule be revised to reflect the site-specific conditions encountered. Typically, the inspection schedule for subsequent years is reduced to semi-annual inspection. ® Aqua-Swirl Maintenance ® The Aqua-Swirl 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 free- floating oil and floatable debris can be directly observed and maintained through the manhole access provided directly over the swirl chamber. ® Aqua-Swirl Inspection Procedure ®TM To inspect the Aqua-Swirl, a hook is needed to remove the manhole cover. AquaShield provides a customized manhole cover with our distinctive logo to make it easy for maintenance crews to locate the system in the field. We also provide a permanent metal information plate 714 Page of TM © AquaShield, Inc. 2014. All rights reserved. ® affixed inside the access riser which provides our contact information, the Aqua-Swirl model size, and serial number. ® The only tools needed to inspect the Aqua-Swirl system are a flashlight and a measuring device such as a stadia rod or pole. Given the easy and direct accessibility provided, floating oil 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. Sediment inspection using a stadia rod in a single chamber ® The maintenance trigger for Aqua-Swirl Models AS-3 through AS-13 occurs when the ® sediment pile is within 42 to 48 inches of the standing water surface. For the Aqua-Swirl Model AS-2, maintenance is needed when the top of the sediment pile is measured to be 30 to 32 inches below the standing water surface. AS-2: 42- 30-32 ®® Maintenance trigger for Aqua-Swirl Models AS-Maintenance trigger for Aqua-Swirl Model 3 through AS-13 occurs when sediment pile is AS-2 occurs when sediment pile is 30 to 32 42-48 inches below water surface. inches below water surface. 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. 814 Page of TM © AquaShield, Inc. 2014. All rights reserved. ® The Aqua-Swirl design allows for the sediment to accumulate in a semi-conical fashion as illustrated above. That is, the depth to sediment as measured below the water surface may be less in the center of the swirl chamber; and likewise, may be greater at the edges of the swirl chamber. ® Aqua-Swirl Cleanout Procedure ® Cleaning the Aqua-Swirl is simple and quick. Free-floating oil and floatable 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 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 (hidden or ® -Swirl, there are no restrictions to impede on-site maintenance tasks. Disposal of Recovered Materials Disposal of recovered material is typically handled in the same fashion as catch basin cleanouts. TM AquaShield recommends that all maintenance activities be performed in accordance with appropriate health and safety practices for the tasks and equipment being used. TM® AquaShield also recommends that all materials removed from the Aqua-Swirl and any external structures (e.g, bypass features) be handled and disposed in full accordance with any applicable local and state requirements. ® Vacuum truck quickly cleans the Aqua-Swirl from a single chamber ® Aqua-Swirl Inspection and Maintenance Work Sheets on following pages 914 Page of TM © AquaShield, Inc. 2014.

Clean liquids from system if one half (½) inch or more oil is present. ® Note: Water in Aqua-Swirl can appear black and similar to oil due to the dark body of the surrounding structure. Oil may appear darker than water in the system and is usually accompanied by oil stained debris (e.g. Styrofoam, etc.). The depth of oil can be measured with an oil/water interface probe, a stadia rod with water finding paste, a coliwasa, or collect a representative sample with a jar attached to a rod. 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.For Aqua-Swirl Models AS-3 through AS-13, schedule cleaning if value in Step #2 is 48 to 42 inches or less. ® 4.For Aqua-Swirl Model AS-2, schedule cleaning if value in Step #2 is 32 to 30 inches or less. 1014 Page of TM © AquaShield, Inc. 2014. All rights reserved. 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. 4.Inspect downstream (convergence) structure(s) for sign of blockage or structural failure as noted above. CLEANING TM Schedule cleaning with local vactor company or AquaShield to remove sediment, oil 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. All cleaning activities should be performed in accordance with property health and safety procedures. TM® AquaShield always recommends that all materials removed from the Aqua-Swirl 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 every three (3) months and clean the system as needed. The ® Aqua-Swirl should be inspected and cleaned at the end of construction regardless of whether it has reached its maintenance trigger.

Ò SNOUT Stormwater Quality System Maintenance Considerations Background: Ò The SNOUT system from Best Management Products, Inc. (BMP, Inc.) is based on a vented hood that can reduce floatable trash and debris, free oils, and other solids from Ò stormwater discharges. In its most basic application, a SNOUT hood is installed over the outlet pipe of a catch basin or other stormwater quality structure which incorporates Ò a deep sump (see Figure 1). The SNOUTforms a baffle in the structure which collects floatables and free oils on the surface of the captured stormwater, while permitting heavier solids to sink to the bottom of the sump. The clarified intermediate layer is Ò forced out of the structure through the open bottom of the SNOUT by displacement from incoming flow. The resultant discharge contains considerably less unsightly trash and other gross pollutants, and can also offer modest reductions of free-oils and finer solids. As with any structural stormwater quality BMP (Best Management Practice), design and Ò maintenance considerations will have a dramatic impact on SNOUT system performance over the life of the facility. The most important factor to consider when Ò designing structures which will incorporate a SNOUT is the depth of the sump (the sump is defined as the depth from beneath the invert of the outlet pipe to the bottom of the structure) . Simply put, the deeper the sump, the more effective the unit will be both in terms of pollutant removals and reducing frequency of maintenance. More volume in a structure means more quiescence, thus allowing the pollutant constituents a better chance to separate out. Secondly, more volume means fewer cycles between maintenance operations, because the structure has a greater capacity. Maintenance Recommendations: · Monthly monitoring for the first year of a new installation after the site has been stabilized. · Measurements should be taken after each rain event of .5 inches or more, or monthly, as determined by local weather conditions. · Checking sediment depth and noting the surface pollutants in the structure will be Ò helpful in planning maintenance. The pollutants collected in SNOUT equipped structures will consist of floatable debris and oils on the surface of the captured water, and grit and sediment on the bottom of the structure. · It is best to schedule maintenance based on the solids collected in the sump. Optimally, the structure should be cleaned when the sump is half full (e.g. when 2 feet of material collects in a 4 foot sump, clean it out). · Structures should also be cleaned if a spill or other incident causes a larger than normal accumulation of pollutants in a structure. · Maintenance is best done with a vacuum truck. · If oil absorbent hydrophobic booms are being used in the structure to enhance hydrocarbon capture and removals, they should be checked on a monthly basis, and serviced or replaced when more than 2/3 of the boom is submerged, indicating a nearly saturated state. · All collected wastes must be handled and disposed of according to local environmental requirements. · Ò To maintain the SNOUT hoods themselves, an annual inspection of the anti- siphon vent and access hatch are recommended. A simple flushing of the vent, or gentle rodding with a flexible wire are all that’s typically needed to maintain the anti-siphon properties. Opening and closing the access hatch once a year ensures a lifetime of trouble-free service.
