 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 StormFilter 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 ofthe 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 u nit, 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 flow rate per drainage pipe. Record all observations.


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