Construction Limited (GCL) has been commissioned to design and construct the
Contract No. HY/2012/07 ¡V Tuen Mun Chek Lap Kok Link ¡V Southern Connection
Viaduct Section for the Highways Department (HyD) of the Government of the
Hong Kong Special Administrative Region (HKSARG). The Works to be executed comprise the
construction of a dual 2-lane elevated carriageway between the HZMB HKBCF and
North Lantau Highway (NLH) with associated slip roads, as well as modifications
and realignment of sections of the NLH and
The Spill Response Plan (SRP) has
been developed in accordance with Condition 2.7 of the Environmental Permit
(EP-354/2009/A) for the Highways Department Contract namely Contract No.
HY/2012/07 ¡V Tuen Mun Chek Lap Kok Link ¡V Southern Connection Viaduct Section.
The SRP shall describe the actions to be taken in the event of
accidental spillage of oil or other hazardous chemicals from construction
activities including vessels operating for the Contract, with specific
provisions for protecting marine ecology and the Chinese White Dolphins.
In order to minimize the possibilities of accidental spillage of oil or
other hazardous chemicals at the construction site and on vessels, the
following precautionary measures will be implemented on site as far as
possible:
¡P
Use drip trays for
storage containers of chemical oil fuel tanks and / or generators.
¡P
Reduce the danger of
stacked containers of oil or chemicals falling.
¡P
Provide tightly closed
lids so as to avoid leakage of chemicals and chemical waste especially if
accidentally knocked over.
¡P
Store chemicals and
chemical waste in separate storage areas.
¡P
Inspect the storage area
regularly to detect if any leakage has occurred or if any of the containers
become defective on a regular weekly basis.
¡P
Use suitable containers,
which are resistant to the stored chemicals or the chemical waste so as to
prevent leakage.
¡P
Label the storage
containers and the chemical tanks according to the EPD¡¦s ¡§Code of Practice on
the Package, Labelling and Storage of Chemical Wastes Labelling¡¨.
¡P
Provide adequate
ventilation in the storage area as necessary.
¡P
Prohibit open flames and
smoking near the chemical storage and fuel storage areas.
¡P
Store large and heavy
containers on the floor as far as possible and avoid storing these containers
higher than 0.75m above the floor level (storage in vessel / barges are
exclusive).
¡P
Keep all chemical,
chemical waste and fuel oil storage containers below eye level for easy
inspection.
¡P
Provide adequate space
for safe and easy handling and inspection of the containers.
¡P
Maintain an up-to-date
log of all chemicals, chemical waste and fuel oil stored at site.
¡P
Separate incompatible
chemicals from one another.
¡P
Keep the ingress to the
chemical storage area locked and restrict access.
¡P
Provide a bucket of dry
sand and a suitable fire extinguisher in the storage area.
In order to minimize the chance of accidental spillage occurring during
the transportation of chemicals or containers of chemicals to and from the
construction site, some precautionary measures will be implemented on site.
These precautions are subject to site conditions and constraints. These are:
¡P
Use a suitably sized
container so as to avoid overfilling.
¡P
Use pumps to transfer
chemical waste instead of manually pouring them.
¡P
Provide a containment
structure able to hold any chemical or chemical waste that is accidentally
spilled.
¡P
Use proper, safe and
suitably labelled containers.
¡P
Use suitable carrying
equipment to transfer the chemical and chemical; waste containers from one
location to another.
¡P
Only employ and use
suitably licensed, trained and responsible chemical waste collection persons to
carry out the transportation requirements.
¡P
Small amount of cement
will be used for grouting back of sampling core. However, cement bags will be
stored up with bunding and covered by tarpaulin all the time when over 20 bags
per a location. Spillage would be confined by boom or silt curtain to avoid
further dispersion.
¡P
Bentonite will be stored
in a silo and the capacity to accommodate 110% of the volume of bentonite or
20% by volume of bentonite stored. Connection pipes shall be check and
maintenance frequently to prevent accidental spillage. Spillage would be
confined by boom or silt curtain to avoid further dispersion.
The general response to the spill shall be carried out to minimize the amount
of oil or hazardous chemicals to the marine environment. The location of the spill is also a
consideration. The general
responses are classified in difference scenarios and they are illustrated in a
flowchart as shown in Appendix A.
Workers should be made aware of the emergency telephone numbers,
locations of emergency showers, location of spill kits and emergency evacuation
routes. Medical emergency response
should also be undertaken whenever necessary. The response actions to an incident
should include, but not limit to, the following steps:
1. Immediately inform the Emergency Team of the spill incident occurring.
2. Take all possible measures to reduce or stop the spillage, such as shut
off the valve.
3. Provided it is safe to do so, the area containing the spill shall have
forced ventilation installed in order to make a safe spillage condition.
4. The Emergency Team shall be responsible for organizing the manpower to
identify the spill source and stop or cease it.
5. The Emergency Team as the assigned person shall equip all people
involved in the clean-up works suitable personal protective equipment prior to
the removal of any leaked chemical or chemical waste.
6. If possible and practical, the spilt chemical shall be put back into the
containers of origin. Otherwise a
suitable material like dry sand or sawdust shall be used to absorb the leakage.
7. Any contaminated sand / sawdust / other materials shall be collected and
put into black plastic bags and shall be clearly labelled as "chemical
waste".
8. All collected chemical waste shall be placed in an area designated for
chemical waste storage.
This type of spill is considered the most serious in terms of the
possibility of causing impact to the local cetacean community and other marine
organisms. The notification system is separated into two scenarios, as
determined by the area of spillage of 100m2.
Before commencement of marine works, sufficient standard Spill Kits will
be available on site up to control marine spillage of up to 100m2 in
size. The standard Spill Kits
includes items such as pads, pillow and Secondary Oil Containment (SOC). SOC is used to enclose the spillage area
to contain the spillage spreading outside of the SOC. There are 30 nos. of SOC
to be available on site. The pads and pillow are used for absorbing and
removing the spillage within the SOC.
Standard spill kits are attached in Appendix B.
It is the responsibility of all persons observing the spill to report
this immediately to their immediate supervisor who shall inform the Emergency
Team Leader. A site agent in Emergency Team shall be assigned to lead a working
team and to deploy the Spill Kits to the spillage site. Depending on the scale
of the spillage area of 100m2, there are two scenarios of spill
response procedures to be applied.
¡P
Emergency Team shall inform
all parties such as Environmental Team (ET), Supervisory Officer Representative
(SOR), Highways Department (HyD), Independent Environmental Checker (IEC),
Marine Department (MD), Fire Services Department (FSD), Agriculture, Fisheries
and Conservation Department (AFCD), Environmental Protection Department (EPD)
and the GCL emergency team members immediately. The contacts of the other concerned
parties tabulated are in Appendix C.
¡P
The Emergency Team shall
be responsible for organizing the manpower to identify the spill source and
stop or cease it.
¡P
The Emergency Team is
the assigned persons who shall equip with suitable personal protective
equipment to remove any leaked chemical or chemical waste.
¡P
The spillage area shall
be contained by using secondary oil containment (SOC).
¡P
Pads and pillow of the
spill kit shall be applied to absorb and remove the spillage within the
SOC. They will be collected by
disposal bags as part of the spill kits item.
¡P
The used spill kits will
be treated, stored and disposed of as chemical waste according to the necessary
procedures.
¡P
An incident report will
be submitted to the SOR & ENPO/IEC within 2 working days.
¡P
The Emergency Team shall
inform the parties such as SOR, ENPO/IEC, ETL and the GCL emergency team
members.
¡P

The use of booms is an effective containment method and can also act as
a barrier to dolphins. Deployment of such with concomitant visual and acoustic
observations is appropriate for small and controllable spills that can be dealt
with in the short term.
In the event of larger spills, GCL will provide and deploy physical
barriers (such as silt curtains, 1 no. , approx. size in 10m x 3m) would be an
effective means of keeping dolphins out of the contaminated area until such
times as the area was free of contamination. The physical barrier will be
available on working barge or loading platform.
If dolphins were found within spillage areas, Dolphin Specialist or his
delegates (refer to Table 1) will be consulted via phone call first for this
case. He/she will be on-site to handle such incidence within 2 hours.
An emergency team shall be established for the Contract in order to
dealing with spillage cases promptly. The emergency team shall comprise members
of an emergency coordinator, emergency safety and environmental representatives
and team members. Table 1 lists the
members¡¦ names and contact numbers of the emergency team.
