Progress
on Investigations into the Location of Permanent Aviation Fuel Receiving
Facility for Hong Kong International Airport (without Attachment
1)
(ACE
Paper 38/2000)
For information
PURPOSE
The purpose of the paper is to update Members on the current position
regarding the search for a suitable site for a permanent aviation
fuel receiving facility for Hong Kong International Airport.
- Members are invited
to note that:
- This paper has
been prepared in response to Members' request for an update
on the current position.
- The Authority
decided in 1999 not to pursue East of Soko Islands and Kau
Yi Chau sites;
- The site search
had failed to find any suitable site in Hong Kong Waters,
other than north of Lantau.
- The Authority
decided to focus its effort north of Lantau and thus the transit
of large aviation fuel vessels through Ma Wan Channel was
revisited by conducting a quantitative risk assessment study
update.
- Results have shown
that the societal and individual risks associated with the
transit of aviation fuel in large tankers through Ma Wan Channel
can now be reduced to ALARP. It is therefore believed that
the Ma Wan Channel can be transited by large aviation fuel
tankers;
- As a result, the
Authority in conjunction with Government has re-evaluated
all possible options north of Lantau and is now focussing
on 3 sites , namely Tuen Mun West , Tuen Mun Area 38 and Sham
Shui Kok and seeks Members' views on these options;
- Item (d) and (e)
above are the reasons why little progress has been made in
identifying a feasible site for the permanent aviation fuel
receiving facility since the Authority last reported to ACE
in 1998.
- It is anticipated
that the permanent aviation fuel receiving facility will be
operational between year 2005 and 2007 depending on the site
selected; and
- The Aviation Fuel
Receiving Facility (AFRF) at Sha Chau will remain under interim
use, but will revert to an emergency back-up facility once
the permanent facility is available.
BACKGROUND
Site
Search since September 1998
- The Authority last
updated Members on the issue in September 1998 (ACE Paper 40/98).
At that time it was decided not to pursue the two options south
of Lantau due to their potential environmental impact, high cost,
long time frame and operationally inferior facilities.
- The position thus
reached in early 1999 was effectively:
- Options south
of Lantau had been ruled out; and
- Tuen Mun West
had been earmarked by the Authority as a potential site.
- At that time the Authority,
in the absence of a suitable site, sought Government's views on
the way forward. It was determined that it would be worthwhile,
due to change in circumstances, to revisit the question of risk
to life associated with Ma Wan Channel being used for the transit
of large aviation fuel tankers. The risk assessment update consultancy
was awarded in early 2000.
Ma Wan
Channel Hazard Assessment Study
- The outcome of the
previous (1993) Ma Wan Channel Hazard Assessment Study was that
the use of the Channel for ocean-going aviation fuel tankers did
not gain Government support. The reason for this was that the
transit of large tankers through the Channel exhibited levels
of risk that could not at that time be mitigated to a level as
low as reasonably practicable (ALARP). Options which did not involve
the use of the Channel (i.e. south of Lantau) were considered
feasible at that time, and therefore options north of Lantau were
shelved.
- The risk assessment
update took note of changes since the 1993 Study, which include
the introduction of vessel traffic control through the Channel
and the introduction of restrictions to transit of vessels during
periods of low visibility. The study update concluded that the
societal and individual risks associated with the transit of aviation
fuel in large tankers through Ma Wan Channel can now be reduced
to ALARP, and are therefore acceptable.
- Government Departments
including EPD, MD and EMSD reviewed the study update and concluded
in October 2000 that there were no insurmountable problems in
allowing large aviation fuel vessels to transit Ma Wan Channel
subject to detailed assessment of mitigation measures to show
compliance with ALARP risk guideline. Thus, sites north of Lantau
making use of Ma Wan Channel, which were excluded in the 1993
Study, are now available for reinvestigation.
Possible
Options
- Three options have
emerged, determined jointly with Government. They are located
in Tuen Mun West, Tuen Mun Area 38 and Sham Shui Kok, as shown
on the plan in Attachment 1. All sites are on Government land/water.
- As soon as one of
these options is selected, it would be subject to full EIA. Currently
it is expected that a final decision on a site will be taken in
2001.
- For Tuen Mun West,
Government would take at least two years to decide whether this
option is available for the aviation fuel facility as the site
is earmarked for port development. A study by Government will
commence late next year. If a green light is given in 2002, reclamation
and construction of the aviation fuel facility would only be completed
by around 2009. This option therefore does not meet the Authority's
time frame. However, if Government were to delink it from the
port development study, which covers about 200 ha, and separately
offer a small part of the site (6 ha) to the Authority, the facility
could be completed around 2007.
- Sham Shui Kok poses
similar problems. It also requires reclamation. The earliest completion
date for this option is 2007.
- In terms of timeframe,
Tuen Mun Area 38 appears to be a better option, as it could be
completed as early as 2005. The area is currently earmarked for
the 4th Industrial Estate Development. The total available area
is 40 ha, of which about half has already been reclaimed. The
Authority is now working with Government to investigate the possibility
of using about 6 ha of the reclaimed land for the aviation fuel
facility.
- AA would consult ACE
during the EIA process.
Environmental
Issues at Tuen Mun West, Sham Shui Kok and Tuen Mun Area 38
- The proposed aviation
fuel facility is classified as a "Designated Project" under the
EIA Ordinance and an environmental permit is required prior to
project commencement for either of the three options.
- It is expected that
items to be covered in the EIA will be largely similar for each
of the three options identified, albeit with different emphasis
on certain items dependent on location. Common areas to be addressed
would include noise (including underwater noise), air, visual
impact, risk to life, water quality and marine ecological impacts
covering both the construction and operational phases. Aviation
fuel spill modelling and forecasting studies might also be required.
- A key issue is the
potential impact on marine mammal population and this aspect will
be fully addressed for the selected option. The design and construction
methodology proposed for jetty construction is of key concern
and this will be carefully considered. Cumulative impacts arising
from all proposed developments in the vicinity of each option
will also be considered, as will the construction and operational
impacts of proposed pipeline routes. Two alternative pipeline
routing options would be considered at the EIA stage for either
of the Tuen Mun options, one connecting directly to the existing
facility at Sha Chau (reducing the requirement for new submarine
pipeline by 50%), and one extending to the western side of the
airport.
- The Authority would
be mindful of the impacts on the marine park when assessing the
feasibility of the various options.
- Based on an initial
understanding of each of these potential impacts, and the likely
mitigation measures required, it is anticipated that none of the
three options should present any insurmountable problems within
the context of a full EIA, bearing in mind the Authority's previous
construction and operational experience of the AFRF at Sha Chau.
- Nevertheless, the
environmental benefits and disbenefits of the three options will
be compared and carefully considered in the selection of a preferred
option. There will be public consultation on the selected site
within the EIA process.
Other
Studies and Approvals required for Tuen Mun West, Sham Shui Kok
and Tuen Mun Area 38
- Other studies and
approvals for the three options are expected to be similar, viz,
Marine Traffic Impact Assessment, and for meeting requirements
under OZP in compliance with the Town Planning Ordinance and the
Foreshore and Seabed Ordinance.
Performance
of Environmental Mitigation Measures in Place at Sha Chau
- Members are advised
that the AFRF at Sha Chau continues to function very well. Operational
mitigation measures continue to be implemented in full by AFSC
Operations Limited with all activities regularly audited by the
Authority's environmental team. Mitigation measures include:
- enforcement of
a zero discharge policy for solid and liquid wastes from the
AFRF at Sha Chau;
- maintenance of
a comprehensive spill response capability, including regular
staff training as well as combined spill response training
exercises involving EPD's Marine Pollution Control Unit, AFCD,
FSD and other Statutory Authorities; and
- continued use
of dedicated fuel vessels with enhanced manoeuvrability and
piloted by crews briefed on 'dolphin friendly' operations
in a Marine Park.
- Members may also wish
to know that two additional six-month phases of dolphin monitoring
have been completed by AFSC Operations Limited's consultants in
waters around the operational facility. The most recent study
concluded that estimates of dolphin abundance do not show any
decreasing trend in north Lantau waters and dolphin populations
now appear to be stable in the area (Attachment 2).
- The Authority also
recently commissioned an assessment of underwater noise levels
in waters around Sha Chau in order to confirm whether the noise
performance of aviation fuel delivery vessels meets the requirements
stipulated by the Authority. The study concluded that the stipulation
is being met (Attachment 3).
- The Authority will
continue to pay for the operating costs of the Lung Kwu Chau and
Sha Chau Marine Park, until the AFRF at Sha Chau reverts to an
emergency back-up facility. The Way Forward
- The Authority remains
committed to expediting completion of a permanent aviation fuel
facility.
- Selection of a site
will be from the three options, namely, Tuen Mun West, Sham Shui
Kok and Tuen Mun Area 38. Environmental merits and demerits of
each of these options will be a major consideration in the selection.
A decision on the selection of a site is expected in year 2001.
- As soon as the site
is selected, the Authority will inform Members of the time frame
for completion of the project, aiming to fast track it, so that
the AFRF at Sha Chau can revert to an emergency back-up facility
as soon as possible.
