The Government of Hong Kong SAR will develop the Integrated
Waste Management Facilities (IWMF) Phase 1 (hereafter ¡§the Project¡¨) with
incineration to achieve substantial bulk reduction of unavoidable municipal
solid waste (MSW) and to recover energy from the incineration process.
The IWMF will be on an artificial island to be formed by reclamation at the
south-western coast of Shek Kwu Chau. Keppel Seghers ¡V Zhen Hua Joint Venture
(KSZHJV) was awarded the contract under Contract No. EP/SP/66/12 Integrated
Waste Management Facilities Phase 1 to construct and operate the Project.
An environmental impact assessment (EIA) study for the
Project have been conducted and the EIA Report was approved under the
Environmental Impact Assessment Ordinance on 17 January 2012. An Environmental
Permit (EP) (EP No.: EP-429/2012) was granted to EPD on 19 January 2012 for the
construction and operation of the Project. Subsequently, the EP was amended (EP
No.: EP-429/2012/A) and a further EP (FEP) (EP No.: FEP-01/429/2012/A) was
granted to the Keppel Seghers ¡V Zhen Hua Joint Venture (KSZHJV) on 27 December
2017.
Pursuant to Condition 2.14 of the Further Environmental Permit (FEP),
the Keppel Seghers ¡V Zhen Hua Joint Venture (KSZHJV) shall prepare a Vessel Travel Details to minimize the chance of vessel collision and
disturbance to the Finless Porpoise and White-bellied Sea Eagle arising from

The construction and associated vessels are
divided into three categories:
2.4.1 Non self-propelled Vessels
This category includes derrick barge, jack
up barge, spreader pontoon, hopper barge, DCM barge, PVD barge, Marine Site
Investigation barge and vessel to transport precast concrete caisson etc. These
types of vessels will be stationary within the construction site area most of
the time. The positioning / re-positioning of these vessel types shall be
assisted by tug boats and anchor boats at a very low speed, less than 5 knots.
2.4.2 Self-propelled Vessels
This category includes TSHD, pelican barge,
tug boat, anchor boat and connection boat. When moving to and from the
construction site area, these vessels may be able to travel at slow to
intermediate speed (up to around 20 knots). However, within the project site
boundary, they mainly operate at slow moving speed (around 5 knots up to
maximum of 10 knots). These vessels generally have high maneuverability. The
project site boundary is shown in Figure 2.
2.4.3 Vessels Delivering Materials to and
from the Project Site
This category includes TSHD, pelican barge,
derrick barge, hopper barge and flat top barge etc. These are large, slow
moving vessels while the last three types of barges are non self-propelled
vessels that rely on tug boats for maneuvering. These vessels will be travel at
slow moving speed (around 5 knots up to maximum of 10 knots).
3 OUTLINE
OF OPERATIONAL ACTIVITIES DURING OPERATIONAL STAGE
During operation stage, the IWMF shall receive
all the Municipal Solid Waste (MSW) in containers delivered to the Artificial
Island from West Kowloon Transfer Station (WKTS), Island East Transfer Station
(IETS) or Island West Transfer Station (IWTS) using marine transportation
vessels. WKTS, IETS or IWTS vessels will return the empty and clean containers
on their return trip from Artificial Island back to their Refuse Transfer
Station (RTS). In the event that the IWMF obtains the consent of the Employer to
decline the reception of MSW from the WKTS RTS to the Artificial Island during
the Operation Period, the WKTS vessel shall deliver the containers to the
loading/unloading area at WENT Landfill. The WKTS vessels will return the empty
and clean containers on their return trip from WENT Landfill back to their RTS.
Vessels from IETS and IWTS will arrived to IWMF upon request and approval
basis.
It should be noted that the operation of
vessels from the different refuse transfer station (RTS) is not covered under
the KSZHJV¡¦s scope, hence their travelling route will not be part of our study.
Ash and residue containers, accompanied by
up to four (4) sludge containers from the grease trap facility of WKTS and the
recyclable materials containers shall be transported from the Artificial Island
to the loading/unloading area of WENT Landfill. Empty containers will be
delivered on their return trip from WENT Landfill back to Artificial Island.
Non-Dangerous Goods and procurement goods
(e.g. Plant auxiliary equipment) will be transported using the Ash and Residue marine
transportation vessels.
Additionally, there are other general
activities, namely the transportation of visitors and Employer, staff and
subcontractors, fuel and chemicals, mobile and plant equipment material
delivery etc., for vessels travelling to and from the Artificial Island on a
regular basis. The vessels will travel at slow to intermediate speed (up to
around 20 knots) outside the footprint of the IWMF. Within the footprint of the
IWMF, the vessels will operate at slow moving speed (around 5 knots up to
maximum of 10 knots).

4 REGULAR
MARINE TRAVEL ROUTES DURING CONSTRUCTION STAGE
The existing traffic separation scheme and
fairways, such as West Lamma Channel, South Cheung Chau Channel and Adamasta
Channel, will be followed and selected as the major marine travel routes for
mobilization of vessels and delivery of construction materials to the
construction site. The existing traffic separation scheme and fairway plan is
shown in Figure 1.
Most of the non self-propelled vessels
expected to be deployed during construction works are barges associated with
ground improvement works, seawall and breakwater construction, dredging and
reclamation. Most of these vessels and associated tug boats will enter the
construction site area during mobilization periods before commencement of the
relevant phases of the construction works. They will then stay and work within
the construction site area. The associated tug boats will be required to use
the predefined and regular marine routes to maneuver all non self-propelled
vessels when they travel outside the construction site area.
With reference to updated EM&A Manual
Section 6.2.1.11 and Section 6.2.1.12, the regular travel route should avoid
areas with high sighting density of Finless Porpoise as much as possible; and a
speed limit of ten knots should be strictly enforced within areas with high
density of Finless Porpoise. In accordance with the Marine Parks and Marine
Reserves Regulation (Cap. 476A), the same speed limit (10 knots) is required to
be enforced within the existing Sha Chau and Lung Kwu Chau Marine Park and the
Brothers Marine Park. Same condition will be imposed for the planning Marine
Parks (Southwest Lantau Marine Park, South Lantau Marine Park and Marine Park
for three runway system) after their designation.
Also according to updated EM&A Manual
Section 6.2.3.3, a pre-defined practical route to restrict vessel access near
the nest should be adopted to keep vessels and boats as far away from the nest
as possible in order to minimize disturbance on the existing WBSE nest. As an additional precautionary measure to
minimize disturbance on their nestling stage, the vessel travel route should be
adjusted to avoid the foraging ground of the breeding adult birds identified
during White Bellied Sea Eagle monitoring programme. If avoidance of foraging
ground is not feasible, vessel frequency and speed within their foraging ground
near the Project Site should be reduced to minimize any potential impacts.
Therefore, it is not recommended for the vessel travel within 100m from the
White-bellied Sea Eagle¡¦s nest and the vessel travel speed shall less than 10
knots within 100m from the nest of White-bellied Sea Eagle if unavoidable.
Self-propelled vessels and vessels
delivering materials to and from the construction site shall also be required
to use predefined and regular marine routes to reduce disturbance to cetaceans
and White-bellied Sea Eagles due to vessel movement. The construction site area
is illustrated in Figure 2 and separated predefined and regular marine
travel routes shall be described in the below parts with due concerns on the
relevant requirements as stipulated in Updated EM&A Manual and Marine Parks
and Marine Reserves Regulation.
During the inclement weather, the working
vessels will go to Hei Ling Chau Typhoon Shelter by passing the southern tip of
Cheung Chau. The planned marine route shall not pass through the existing and
planning Marine Parks and foraging ground of White-bellied Sea Eagle. The
vessels shall travel less than 10 knots at the hotspot areas of Finless
Porpoise. Please refer to Figure 3 for the marine route.
For disposal of C&D materials, KSZHJV
will deliver the C&D materials to Tuen Mun Area 38 and Tseung Kwan O Area
137. Derrick Barger shall be used to deliver C&D materials off site. The
planned marine route shall not pass through the existing and planning Marine
Parks and foraging ground of White-bellied Sea Eagle. The vessels shall travel
less than 10 knots at the hotspot areas of Finless Porpoise. The marine route
is illustrated in Figure 4.
Sand Fill will be delivered to construction
site from Zhongshan / Zhuhai, Guangdong. The barge will first anchor at the
immigration anchorage area for immigration check at Tuen Mun, then deliver to
the construction site directly. The planned route of working vessels during construction stage shall not travel through the Sha
Chau and Lung Kwu Chau Marine Park. When the vessels are traveling inside the hotspot areas of Chinese
White Dolphin and Finless Porpoise due to safety /
unavoidable reasons, it shall travel less than 10 knots. It is not anticipated for the planned marine route to travel near
the foraging ground of White-bellied Sea Eagle. Please refer to Figure 5
for the detailed marine routing.
Precast concrete caisson will be delivered
to construction site from Shatian / Dongguan, Guangdong directly. Superstructure¡¦s,
Seawall¡¦s and Berth¡¦s precast units will be delivered to construction site from
Xinhui, Guangdong and prefabricated components of incineration plants will be
delivered to construction site from Zhuhai, Guangdong directly. The vessels
will first travel to anchorage ground in the vicinity of Shekou, Guangdong to
go through immigration. The planned route of working vessels during construction stage shall not travel through the Sha
Chau and Lung Kwu Chau Marine Park. When the vessels are traveling inside the hotspot areas of Chinese
White Dolphin and Finless Porpoise due to safety /
unavoidable reasons, it shall travel less than 10 knots. It is not anticipated for the planned marine route to travel near
the foraging ground of White-bellied Sea Eagle. Please refer to Figure 6
for the detailed marine routing.
The connection boats will be used to
transport Supervising Officer¡¦s staff, KSZHJV¡¦s staff and general workers to
and from the construction site. The planned route may
pass through hotspot areas of Finless Porpoise. When the vessels are traveling
inside the hotspot areas of Finless Porpoise, it shall travel less than 10
knots. The planned route is not anticipated to travel
through the marine parks, foraging ground of White-bellied Sea Eagle. The
marine route is shown in Figure 7.
Upon the receipt of Dumping At Sea
Ordinance Permit, the dredged Category L marine sediment shall be disposed of
at the CEDD¡¦s disposal ground at South Cheung Chau. Tug boat and hopper barge
shall be used for disposal of the marine sediment off site. The planned route may pass through hotspot areas of Finless Porpoise.
When the vessels are traveling inside the hotspot areas of Finless Porpoise, it
shall travel less than 10 knots. However, the planned
route is not anticipated to travel through the marine parks, foraging ground of
White-bellied Sea Eagle and hotspot areas of Chinese White Dolphin. The marine
route is shown in Figure 8.
5 REGULAR
MARINE TRAVEL ROUTES DURING OPERATION STAGE
The existing traffic separation scheme and
fairways, such as West Lamma Channel, South Cheung Chau Channel, Adamasta
Channel, Western Fairway, Ma Wan Fairway and Urmston Road Fairway, will be
followed and selected as the major marine travel routes for delivery of ash and
residue between IWMF at Shek Kwu Chau and loading /
unloading area at WENT Landfill.
With reference to updated EM&A Manual
Section 6.2.1.11 and Section 6.2.1.12, the regular travel route should avoid
areas with high sighting density of Finless Porpoise as much as possible; and a
speed limit of ten knots should be strictly enforced within areas with high
density of Finless Porpoise. In accordance with the Marine Parks and Marine
Reserves Regulation (Cap. 476A), the same speed limit (10 knots) is required to
be enforced within the existing Sha Chau and Lung Kwu Chau Marine Park and The Brothers Marine Park. Same condition
will be imposed for the planning Marine Parks (Southwest Lantau Marine Park,
South Lantau Marine Park and Marine Park for three runway system) after their designation.
Also according to updated EM&A Manual
Section 6.2.3.3, a pre-defined practical route to restrict vessel access near
the nest should be adopted to keep vessels and boats as far away from the nest
as possible in order to minimize disturbance on the existing WBSE nest. As an additional precautionary measure to
minimize disturbance on their nestling stage, the vessel travel route should be
adjusted to avoid the foraging ground of the breeding adult birds identified
during White Bellied Sea Eagle monitoring programme. If avoidance of foraging
ground is not feasible, vessel frequency and speed within their foraging ground
near the Project Site should be reduced to minimize any potential impacts.
Therefore, it is not recommended for the vessel travel within 100m from the
White-bellied Sea Eagle¡¦s nest and the vessel travel speed shall less than 10
knots within 100m from the nest of White-bellied Sea Eagle if unavoidable.
The marine travel route is designed with
due concerns on the relevant requirements as stipulated in Updated EM&A
Manual and Marine Parks and Marine Reserves Regulation.
Several lines of connection boat shall be
operated between IWMF at Shek Kwu Chau and Cheung Chau, between Shek Kwu Chau
and Central and between Shek Kwu Chau and Tsim Sha Tsui. The planned route of working vessels during operation stage should
not travel through the existing marine parks and planned marine parks in the
western waters and the vessels shall travel less than 10 knots when travelling inside the hotspot
areas of Chinese White Dolphin and Finless Porpoise and foraging ground of
White-bellied Sea Eagle due to safety / unavoidable reasons. The marine route
during operational stage is shown in Figure 9.
Up to the current moment, the delivery
route of Dangerous Goods, Fuel, Vehicular ferry and other consumables
transportation route to Shek Kwu Chau is not yet confirmed. Such marine routing
will be provided once available to avoid the vessel
travel through the existing marine parks and planned marine parks in the
western waters.
6 VESSEL
CAPTAIN TRAINING
6.1
Vessel Captain Training
KSZHJV shall provide training (e.g. by Environmental
Officer/Environmental Supervisor) to vessel captains to
ensure vessel operation poses minimal risks to Chinese White Dolphin, Finless Porpoise
and minimal disturbance to White-bellied Sea Eagles. The training shall include
briefings on predefined routes, general education on local cetaceans and
white-bellied sea eagles, the required environmental practices / measures while
operating construction and associated vessels under the Project, guideline for
operating vessel safely in the presence of Chinese White Dolphin and Finless
Porpoise and guideline of restriction on vessel access near the nest of White
bellied Sea Eagle. KSZHJV shall also schedule the training with individual
marine contractors and shall ensure all marine vessel captains working on the
Project are adequately briefed and trained prior to marine construction or
prior to operating vessels within the construction site area.
The same arrangement shall be adopted for
vessel captains during operation stage. The training record shall be kept on
site / office for both construction stage and operation stage. Participant
shall sign his name and title on the training record.
6.2
General education on local cetaceans and white-bellied Sea Eagles
The appearance, distribution and hotspots
areas, behavior and conservation status of the local cetacean species and
White-bellied Sea Eagles will be described in the training sessions. The
seasonal variation patterns of the local cetaceans and the location of nest of
White-bellied Sea Eagles and the sensitivity of White-bellied Sea Eagles to
human disturbance during breeding season will be mentioned in the training
sessions.
6.3
Marine Parks and Hotspot Areas of Chinese White Dolphin and Finless Porpoise
The proposed marine travel routes for
vessels to be operated during construction and operational stages shall avoid
all existing Marine Parks in the western waters (including Sha Chau and Lung Kwu
Chau Marine Park, The Brothers Marine Park) and the proposed Marine Parks in
the western waters (including Southwest Lantau Marine Park, South Lantau Marine
Park, and Marine Park for three runway system) and the Chinese White Dolphin and
Finless Porpoise Hotspot Areas.
The location of Marine Parks in the western
waters and Chinese White Dolphins and Finless Porpoise hotspot areas are
attached in Appendix B.
6.4
Speed Limits and Guidelines for Safe Vessel Operations in the Presence of
Chinese White Dolphin / Finless Porpoise
One of the major human-caused threats to
Chinese White Dolphins / Finless Porpoise is injury / death due to marine
vessel collision. Locations with frequent Chinese White Dolphin / Finless
Porpoise sightings near the proposed vessel routes should be traversed with
more caution to avoid impact on Chinese White Dolphins / Finless Porpoise.
Reference may be made to the ¡§Code of Conduct for Dolphin Watching Activities¡¨
published by AFCD and other relevant sources. A code of conduct for
construction and associated vessels in the presence of Chinese White Dolphin /
Finless Porpoise is provided in Appendix C. The following measures are
also considered to be helpful to minimize the chance of a vessel striking
Chinese White Dolphin / Finless Porpoise and will be covered in training
sessions:
ŸAll vessels will travel at a speed no greater than 10 knots in the
construction site area, which is demarcated by yellow marker buoys;
ŸThe vessel captain should always remain a vigilant for the presence
of Chinese White Dolphin / Finless Porpoise and make sure they slow down prior
to passing known Chinese White Dolphin / Finless Porpoise hotspot areas, and
take actions, e.g. never chases and cut across the course of Chinese White Dolphin
/ Finless Porpoise, to avoid disturbance to or collisions with Chinese White
Dolphin / Finless Porpoise, the vessel shall travel less than 10 knots within
the hotspot areas of Chinese White Dolphin / Finless Porpoise if unavoidable;
ŸConstruction and associated vessels should avoid traversing through all
existing Marine Parks in the western waters (including Sha Chau and Lung Kwu
Chau Marine Park, The Brothers Marine Park) and the planned Marine Parks in the
western waters (including Southwest Lantau Marine Park, South Lantau Marine
Park, and the proposed marine park for three runway system);
ŸAll working vessels used for the construction and operational stages
(including construction and associated vessels, operation vessels and
transportation vessels) shall not anchor or stopover
within the existing and all planned Marine Parks, as aforementioned, in the western
waters;
6.5
Guideline of Restriction on vessel access and speed limit near the nest of
White-bellied Sea Eagle
White bellied Sea Eagle are known to be
sensitive to human disturbance during breeding season, and may even desert a
nest if disturbed. A pre-defined practical marine route to restrict vessel
access near the nest should be adopted to keep vessels and boats as far away
from the nest as possible. As an additional precautionary measure to minimize
disturbance on their nestling stage, the vessel travel route should be adjusted
to avoid the foraging ground of the breeding adult birds identified during
White Bellied Sea Eagle monitoring programme. If avoidance of foraging ground
is not feasible, vessel frequency and speed within their foraging ground near
the Project Site should be reduced to minimize any potential impact. The vessel
travel speed should be less than 10 knots within 100m from the nest of
White-bellied Sea Eagle, if unavoidable. As the location of White-bellied Sea
Eagle¡¦s nest is not facing the Project Site, it is not anticipated for the vessels
for both construction and operational stages to travel near the nest.
Nonetheless, it is still recommended the frequency of vessel within the
foraging ground shall be less than 10 numbers of vessels per day.
The location plan of the nest of
White-bellied Sea Eagle and the 100m boundary from the nest is attached in Appendix
D.
6.6
Required environmental practices / measures
The vessel shall travel less than 10 knots
inside the Project Area, inside the hotspots areas of Chinese White Dolphin and
Finless Porpoises, within 100m from the nest of White-bellied Sea Eagles and
the vessel shall avoid to pass through the existing Marine Parks. Some good
environmental practices such as no release of foam, oil grease or other
objectionable matter into the waters, minimize wastewater generation and treat
all effluent before discharge and no dumping of rubbish, food, oil or chemicals
into the waters.
7 MONITORING
KSZHJV will maintain records of the use of
the connection boats under control. Such records will include, inter alia,
details, times and purpose of journeys including the vessel number. The person
using the works boats authorizing the journey will be required to sign his name
and title against the entries. KSZHJV will present current log books for
inspection by the SOR when required. The following monitoring measures will be
adopted.
ŸSelf propelled Vessels including THSD, pelican barge, tug boats,
anchor boat and connection boat will be installed with Automatic Identification
System (AIS) for the purposes
of recording and tracking
marine travel routes on website during operation;
ŸNon self-propelled Vessels including Derrick barges, hopper barge,
flat top barges, jack up barges etc. will be steered by the tug boats which are
installed with AIS. As such,
their travel routes can be followed;
ŸAdministrative control such as AIS system will be taken, one route will be randomly selected and
checked once per month; and
ŸFront End Mobile Units had been installed in the barges for
disposing marine sediment in CEDD dump pit at South of Cheung Chau.
KSZHJV will ensure
that self propelled vessels involved during construction and operation phases
would be equipped with AIS or GPS.
The daily record of marine travel route of
offsite working fleets will be collected and filed by the supervising staff for
inspection monitoring purposes. Record shall be submitted upon SOR¡¦s request.
Warning will be noticed to the captain and his shipping company or material
suppliers if vessel track log showed the approved marine travel route is not
followed.
All vessels used for the construction and
operational stages will comply with all the relevant regulations and
requirements of the Marine Department, including:
ŸThe Shipping and Port Control Regulation (Cap. 313A)
ŸThe Merchant Shipping (Miscellaneous Craft) Regulations (Cap. 313F)
ŸThe Merchant Shipping (Safety) (Signals of Distress and Prevention
of Collisions) Regulations (Cap. 369N)
