2.3        MAINTENANCE CREW REQUIREMENTS


Table 4 lists the anticipated crew requirements for maintenance operations. Removal of water and sediments

during major maintenance activities can be accomplished using either a pump and water truck or a vacuum
truck. All applicable safety (OH & S) and disposal regulations should be followed. A general description of the
maintenance activities follows.

2.4        MAINTENANCE METHODS


2.4.1      Minor Maintenance/Inspection (Twice A Year)


Minor maintenance typically will involve the steps below, however if it appears that a spill of some type has

occurred, the local hazard control agency and Stormwater360 should be notified immediately. In the case of a
spill, the worker should abort maintenance activities until the proper guidance has been obtained.


Steps for Minor Maintenance

1.         Maintenance to be performed by a skilled worker familiar with Storm Filter units.


2.         If applicable, set up safety equipment to protect pedestrians from fall hazards presented          by open
           doors. Also set up appropriate safety equipment for work near roadways.


3.         Inspect the external condition of the unit and take notes concerning defects/problems.

4.         Open the doors to the vault and allow the system to air out for 5-10 minutes.

5.         Without entering the vault, inspect the inside of the unit, including components.


6.         Take notes about the external and internal condition. This includes inspecting pit penetrations, walls,
           lids, ladders & grates etc.

7.         Give particular attention to recording the level of sediment build-up on the floor of the vault in the

           forebay (or pre-treatment bay), and on top of the internal components. If flow is occurring, note the
           level of water and estimate the fi w rate per drainage pipe. Record allobservations.


8.         Remove large loose debris and trash using a pole with a grapple or net on the end.
