General Maintenance Procedures The structural and functional integrity of the Facility shall be maintained at all times by removing and preventing drainage interference, obstructions, blockages, or other adverse effects into, through, or out of the system. Periodic silt removal shall occur when standing water conditions occur or the pond's storage volume is reduced by more than 10%. Silt shall be removed and the pond/basin returned to original lines and grades shown on the approved engineering plans. In addition, corrective measures are required any time a basin does not drain completely within 72 hours of cessation of inflow. NO STANDING WATER IS ALLOWED in basins designed for dry detention purposes. Accumulated litter, sediment, and debris shall be removed every 6 months or as necessary to maintain proper operation of the basin. Disposal shall be in accordance with federal, state and local regulations. Detention facilities shall be mowed monthly between the months of April and October or anytime vegetation exceeds 12-inches in height. To prevent debris from entering and clogging the downstream storm sewer system a wire mesh screen or similar screening device shall be installed over the outlet until final acceptance. 4. PREVENTIVE MAINTENANCE/INSPECTION • Visual inspections of all components will be conducted every 6 months. • A log shall be kept of maintenance actions, and inspections. The log should document the condition of the detention system's primary components, mowing, and silt, litter and debris removal dates. Document aeration of the basin bottoms and replanting to prevent the sealing of the basin bottom. • Written maintenance and repair records shall be maintained by the party or parties signing the attached Agreement and shall be provided to the City upon request.

Pre-treatment best management practices can be as simple as deep � pili 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 StormTech as an effective means to minimize maintenance requirements and maintenance costs.

MANHOLE Sediments are captured in the Isolator Row protecting WITH OVERFLOW the storage areas of the adjacent stone and chambers WEIR 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 ECCENTRIC HEADER 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 OPTIONAL ACCESS STORMTECH CHAMBERS as these chambers do not have perforated side walls. 2 Call StormTech at 888.892.2694 or visit our website at www.stormtech.com for technical and product information. ® StormTech- 2.1 INSPECTION The frequency of Inspection and Maintenance varies by location.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,StormTech 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. ter.

Remove lid from floor box frame 1)Bt 2 1)A) ii. Remove cap from inspection riser iii. Using a flashlight and stadia rod, measure depth of sediment and record results on maintenance log. iv. If sediment is at,or above,3 inch --- depth proceed to Step 2. If not a proceed to step 3. B)All Isolator Rows I. Remove cover from manhole at A6 upstream end of Isolator Row ii. Using a flashlight, inspect down Isolator Row through outlet pipe 1.Mirrors on poles or cameras may be used to avoid a confined space entry 2.Follow OSHA regulations for confined space entry if entering manhole iii. If sediment is at or above the lower row of sidewall holes(approximately 3 inches)proceed to Step 2. If not proceed to Step 3. Step 2)Clean out Isolator Row using the JetVac process A)A fixed culvert cleaning nozzle with rear facing nozzle spread of 45 inches or more is preferable B)Apply multiple passes of JetVac until backflush water is clean C)Vacuum manhole sump as required Step 3)Replace all caps, lids and covers, record observations and actions Step 4)Inspect&clean catch basins and manholes upstream of the StormTech system Sample Maintenance Log D 1' 1 11 1 11 I 1 3/15101 none New installation.Fixed point ie Cl frame at grade djm 9/24/01 6.2 0.1 ft.
