It may be necessary to adjust the Presently, procedures have been developed maintenance activity schedule depending for two levels ot maintenance: on the actual operating conditions • Inspectionlminur maintenance encountered by the system. • Major maintenance. In general, minor maintenance activities wiil occur late in the rainy season, and major Inspectionlminor maintenance activities are maintenance will occur in late summer to combined since minor maintenance does early (all when flows into the system are not not require special equipme�t and typically likely to be present. little or no materials are in need of disposal. Maintenance Activity Frequency Inspectionlminor maintenance typically involves: The primary factor conirolling timing of maintenance for the StormFilter is • Inspection of the vault itself sedimentation. • Removal of vegetation and trash and debris. Major maintenanc2 typically includes: • Cartridge replacement • Sediment remo:al Important: Applicable safety (CSHA) and disposal regulations should be followed during all maintenance activities.
