Precautions
3.1.
General
Precaution
(i)
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:
- The
storage areas of chemicals and chemical wastes on land should be located
remote from the coast and any other water bodies as far as practicable.
- Use
suitable containers, which are resistant to the stored chemicals or the
chemical waste.
- Store
chemicals and chemical waste in separate storage areas.
- Label the
storage containers and the chemical tanks in accordance with EPD’s “Code
of Practice on the Package, Labeling and Storage of Chemical Wastes
Labeling”.
- Drip trays
shall be used to contain oil and chemical drums on site.
- Provide
adequate ventilation in the storage containers/areas, as necessary.
- Prohibit
open flames and smoking near the chemical storage and fuel storage areas.
- Provide
tightly closed lids so as to avoid leakage of chemicals and chemical waste
especially if accidentally knocked over.
- 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.
- Keep all
chemical, chemical waste and fuel oil storage containers below eye level
for easy inspection.
- Provide
adequate space for safe and easy handling and inspection of the
containers.
- Maintain
an up-to-date log of all chemicals, chemical waste and fuel oil stored at
site.
- Separate
incompatible chemicals from one another.
- Keep the
ingress to the chemical storage area locked and restrict access.
- Provide a
bucket of dry sand and a suitable fire extinguisher in the storage area.

Transfer
& Transport Precautions
(i)
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, especially in marine routine, some
precautionary measures will be implemented on site. These precautions are
subject to site conditions and constraints. These are:
- Use a
suitably sized container so as to avoid overfilling.
- Use
proper, safe and suitably labeled containers.
- Provide a
containment structure which is able to hold any chemicals that is
accidentally spilled.
- Use pumps
to transfer chemical waste instead of pouring manually.
- Use
suitable carrying equipment to transfer the chemical and waste containers
from one location to another.
- Only
employ and use suitably licensed, trained and responsible chemical waste
collection companies/persons to carry out the transportation requirements.
4.
General
Response to Spill Incidents
(i)
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 include the following and they are illustrated in the flowchart
below:
4.1.
Proposed
Quantities of Spillage Mitigation Measures and Required Personnel Protective
Equipment (PPE)
(i)
For incidents preparation, we need to purchase stocks of
preventive materials such as oil spill kit or oil sorbent booms, in order to
carry out mitigation measures at once. The following table shows the proposed
quantities of spillage mitigation measures which help to control the spread of
oil within a predictable period of time. The proposed quantities are sufficient
for handling 2 times of marine spillage of up to 100
m2, and will be restocked
at once after use. The reason of doubling the stock is to prevent the running out
of stock when the spillages appear twice in short time. All of the materials,
also with the required PPE, will be purchased and stored in the construction
site area, and accessible by workers and emergency team.
Table
4.1 Proposed Quantities of Oil
Spill Mitigation Measures
(ii)
Other safety equipment and sanitary expends such as fire
extinguishers, protective cloths, brushes, dustpans, mops and buckets, also
with tissue and towelling will also purchase in reasonable quantities to ensure
the cleanliness of the area and the protection of emergency team members.
(iii)
Furthermore, the specification of spill kits is enclosed in
Appendix A. The specification and the content of spill kits provide evidences
of spill removal and the early preparedness before the emergency really happen.
Other kinds of spill bucket will also consider with its utility, and provide
other options for spillage treatment. All
spill kits will be purchased and checked with the effectiveness, validity and
the expiry date in quarterly basis.
4.2.
Spill
contained on the deck of a vessel
(i)
Workers, including sub-contractors’ staff,
should be made aware of the emergency telephone numbers, locations of emergency
showers, location of Spill Kits and emergency evacuation routes. Specific
tool-box training should be provided for all workers. 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 duty Emergency
Coordinator of the spill incident occurring.
2.
The duty Emergency Coordinator shall assess the
situation and identify the source. He shall immediately notify management and
emergency representatives on the emergency contact list.
3.
Where it is safe to do so, he shall take all
possible measures to reduce or stop the spillage, such as shut off the valve.
4.
Where the spill occurs in an enclosed or
confined space, the duty Emergency Coordinator shall handover the area to
safety or emergency services (e.g. Fire Services) to attain safe access and to
manage the situation. Suitable personal protective equipment, including
breathing apparatus, shall be worn as necessary.
5.
The duty Emergency Coordinator shall equip all personnel
involved in the cleanup 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 spill
kits or absorbent material such as dry sand or sawdust shall be used to absorb
the leakage.
7.
Any contaminated sand, sawdust or other
absorbent materials shall be collected and put into suitable and clearly
labeled plastic bags or containers.
8.
All collected chemical waste shall be placed in
a suitably ventilated container, designated for chemical waste storage.
4.3.
Spill
into the Marine Environment
(i)
Spillage in marine environment is serious, as it
will potentially cause impact to the environment and ecology. It is therefore
essential that workers becoming aware of spills immediately notify their
supervisor, who shall inform the duty Emergency Coordinator of the incident.
(ii)
There are two levels of severity, based on the
size of the affected area (i.e. above or below the 100m2 limit). The
response of the duty Emergency Coordinator will be governed by this.
4.3.1. For spillage area larger than 100 m2
·
The duty Emergency Coordinator shall inform all
parties such as Environmental Team (ET), Supervisory Officer’s 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 DBJV emergency team members immediately. The contacts of the other
concerned parties tabulated are in Appendix B.
·
The Emergency Coordinator shall be responsible
for organizing the manpower to identify the spill source and stop it.
·
The Emergency Coordinator shall mobilize a team
to clean up the spill. He shall ensure that the clean-up team is equipped with
suitable PPE for the works.
·
The spillage area shall be contained by using
booms or other separation devices.
·
Pads and Pillow of the Spill Kit shall be
applied to absorb and remove the spillage within the containment. They will be
collected by disposal bags as part of the spill kits item.
·
The used spill kits will be treated, stored and
disposed of as chemical waste according to the necessary procedures.
·
An incident report will be submitted to the SOR
within 2 working days, and also be copied to ENPO/IEC.
4.3.2. For spillage area smaller than 100 m2
·
The duty Emergency Coordinator shall inform the
parties such as Supervisory Officer’s Representative (SOR) and the DBJV
emergency team members.
·
The Emergency Coordinator shall be responsible
for organizing the manpower to identify the spill source and stop or cease it.
·
The Emergency Coordinator is the assigned
persons who shall equip with suitable personal protective equipment to remove
any leaked chemical or chemical waste.
·
The spillage area shall be contained by using
booms or other separation devices.
·
Pads and Pillow of the Spill Kit shall be
applied to absorb and remove the spillage within the containment. They will be
collected by disposal bags as part of the spill kits item.
·
The used spill kits will be treated, stored and
disposed of as chemical waste according to the necessary procedures.
·
An incident report will be submitted to the SOR
within 2 working days, and also be copied to ENPO/IEC.
4.4.
All
Reasonable Attempts to be Made to Keep Dolphins Away from Contaminated Areas
(i)
The use of oil absorbing booms is an effective contamination
management method for small spills within the marine environment. It will
prevent the spread of a spill and thus help to minimize the potential for
Chinese White Dolphins to come into contact with the spill, and can act as a visual
barrier to deter dolphins from entering the site. Deployment of such absorbent
booms, together with concomitant visual and acoustic observations is
appropriate for small and controllable spills that can be dealt with in the
short term.
(ii)
In the event of larger spills, the deployment of
underwater barrier nets at the periphery of the spill area (such as silt
curtains) as physical barriers, and in addition to the measures outline above,
could be an effective means of isolating the spill area from Chinese White
Dolphins.
(iii)
Silt curtain, in addition to the EP required
quantity, will be kept on site for deployment in case of emergencies.
(iv)
If dolphins were found coming into the contained
spillage areas, the environmental representative would inform the Environmental
Team Leader and the dolphin expert (Dr. Samuel Hung) or his representative and
seek their view for appropriate actions. All necessary response action will be
provided by the Contractor before the arrival of the dolphin expert or his
representative, after consulting the dolphin expert’s opinions. We anticipated
that the dolphin expert or his representing dolphin specialist(s) should arrive
on site within 2 hours once they received the reporting of such incidence.
(v)
Emergency response personnel and boat operators
shall be trained by the Environmental Officer or his assigned Environmental
Supervisor in the “Code of Conduct for Dolphin Watching Activities”,
promulgated by the Agriculture, Fisheries and Conservation Department. They
shall follow these codes of conducts while carrying out their duties.
4.5.
Cement
and Bentonite Leakage during Grouting Works and D-wall Construction
(i)
Grouting and D-wall construction works will take
place on the reclaimed land of Northern Landfall (Figure 2) and Southern
Landfall (Figure 3). The Southern Landfall will be reclaimed by others and the
site handed over to HY/2012/08 in a few years’ time, likely from 2016 to 2017. The
site design of the reclaimed land is yet to be developed and not available at
the moment.
(ii)
There will be no floating concrete batching
plants under this Contract.
(iii)
Grouting and D-wall construction works will be
entirely land-based. Any spillage of
cement and bentonite will also likely be land-based.
(iv)
Any spilled cement during the course of
construction of D-walls and grouting works will be left to solidify and cleaned
away as solid waste.
(v)
Any spilled bentonite during the course of
construction of D-walls will be collected at sump-pits at low point within the
site and pumped away for disposal at suitable facility or recycle at slurry
treatment plant when available after 2014.
(vi)
In case of cement or bentonite contaminated
water, they will be managed by the following standard facilities/design which
will be incorporated into the site design:
a.
The site will be sloped inwards from the sea
such as spillage will be retained within the site boundary;
b.
Perimeter u-channels along the site boundary;
c.
Sump-pits within the site;
d.
Wastewater treatment facilities;
e.
Slurry treatment plant for the TBM works (available
after 2014).
(vii)
The contaminated water will be treated to meet
the discharge license standards before discharge.
