    4.   Emergency Procedures

4.1 Spill Procedures



In the event of a spill discharging into any gully pit all sediment is to be extracted and the filter bags are to be
removed and replaced with rejuvenated filter bags. Normal operation procedures apply to additional cleaning
as a result of   spills.



4.2 Blockages

In the unlikely event of surface flooding around a gully pit fitted with an Enviropod the following steps should

be carried out:


Check Enviropod over flow bypass. The Enviropod filter has been designed with an overflow mechanism built
into the filter box. If surface flooding still exists check the overflow slots underneath the rubber seal. If debris
is lodged in the overflow slots these can be easily cleared by hand or steel rod.


If overflow is clear and surface flooding still exists remove Enviropod and check outlet pipe for blockages.


Removal of the Enviropod may be difficult if the filter is clogged and the Enviropod is holding water. If the
filter is clogged, brush the side walls of the filter with a yard broom or similar. This will dislodge particles

trapped at the interface allowing contained water to flow through the filter.

If the outlet pipe is blocked, it is likely that a gully sucker truck will be required to unblock it. Debris should be
removed from the Enviropod with the gully sucker truck before removal of the Enviropod filter.


If a gully sucker truck is not available and the Enviropod needs to be removed by hand, follow the steps below:
.   Remove excess debris by hand or brush the side of the filter.
.   Lift and place filter ring through the filter box and into cage.
.   Remove Filter box.
.   Lift cage containing filter bag and ring out ofthe pit.
.   Unblock outlet pipe.
