4.2 Spill into the Marine Environment
A spill into the marine environment is considered as serious issue in term of the possibility of causing impact to the ecosystem and marine organisms. The notification system is divided into two scales by the approximate area affected by the spill.
Upon the identification of the spillage, standard spill response equipment (such as absorbent pads and pillows, Secondary Oil Containment, oil dispersant, etc.) will be used to contain the spill. Secondary Oil Containment is used to enclose the spill area and to prevent the spill from migrating outside of the Secondary Oil Containment. The pads and pillows are used for absorbing the spill within the Secondary Oil Containment. The example of the standard spill kits are attached in Appendix C.
Once the spillage is found in the marine environment, the person observing must report the details, such as the spillage area, location to their supervisor, who shall inform the superintendent and site agent as the Emergency Team Leader. Base on the scale of the spillage area, the reporting system is divided into the following two system:
i) For a spill area of greater than 100m2 :
Ø The Emergency Team Leader shall inform all the parties such as the Project Manager, Marine Department, Fire Services Department, Agriculture, Fisheries and Conservation Department, Environmental Protection Department, Environment Team and Independent Environment Checker immediately. The contact list of the mentioned parties is attached in Section 8.0.
Ø The Emergency Team Leader shall organize workers to identify the source of spillage and stop it provide it is safe to do so.
Ø The assigned person to remove the spill shall be well equipped with suitable PPE.
Ø Secondary Oil Containment shall be used to contain the spillage area.
Ø Absorbent pads and pillows shall be used to absorb and remove the spill within the Secondary Oil Containment zone.
Ø The used absorbent pads and pillows will be packed and treated as chemical waste.
Ø An incident report will be submitted to ET, IEC and PM within 2 working days.
ii) For a spill area less than 100m2 :
Ø The Emergency Team Leader shall inform all the parties such as the Project Manager, Environment Team and Independent Environment Checker immediately. The contact list of the mentioned parties is attached in Section 8.0.
Ø The Emergency Team Leader shall organize workers to identify the source of spillage and stop it provide it is safe to do so.
Ø The assigned person to remove the spill shall be well equipped with suitable PPE.

5. Dolphin Contingency Plan During Spill Response
It is not known what specific impacts a spill of chemical or chemical waste will have upon the Chinese White Dolphin and its food supply. Hence, the following approach will be applied to isolate the Chinese White Dolphin from any spill response event which may take place in our construction activities:
i) Initial Response
Ø Observation from high platform will be used to determinate the size of spillage.
Ø In addition to identify the size of spillage, checking any Chinese White Dolphin within or in the vicinity of the spillage will be observed from high platform.
Ø The following course of action shall be decided upon the investigation of size of spillage, the present of any Chinese White Dolphin within the spillage and the likelihood of Chinese White Dolphin entering the spillage.
ii) Isolation of Spillage from Chinese White Dolphin
Ø In case the spillage is a small in scale, absorbent booms shall be used to prevent the spread of a spill and thus help to minimize the potential for Chinese White Dolphin to come into contact with the spillage. Together with the observers, our superintendent will organize workers to remove the small spill in a short time.
Ø In the event of spillage of a larger scale, the deployment of underwater barrier nets (surrounding the absorbent booms) in addition to the measures outline above, could be an effective means of isolating the spill area from Chinese White Dolphin. Trained dolphin watchers shall maintain visual contact with any Chinese White Dolphins sighted in the area to ensure dolphins are not trapped within barrier nets. Qualified ecologist will be notified to give advice for further appropriate actions.
Ø In case of the Chinese White Dolphin is found within the enclosed contaminated area of spillage, the same measures will be applied in the event of injury or of live stranded cetaceans, as described in the Dolphin Watching Plan will be followed (i.e. contact immediately through “1823” marine mammal stranding hotline).
