A Permanent Aviation Fuel Facility (PAFF) is required
to ensure a secure means to supply aviation fuel during the operational
lifetime of the Hong Kong International Airport (HKIA). The PAFF will replace the existing temporary Aviation
Fuel Receiving Facility (AFRF) adjacent to Sha Chau,
as the existing facility does not have sufficient capacity. The PAFF must meet the capacity demand for
the 2040 planning horizon of the airport and must be able to provide for
strategic storage. The Airport Authority
Hong Kong (AAHK) is committed to provide a replacement facility, after which
the Sha Chau facility will be used for emergency
backup purposes only. The proposed PAFF
with its associated pipeline and jetty is shown in Figure
1.1.
The proposed project is designated under Sections H.2
and L.4 of Schedule 2 of the Environmental Impact Assessment Ordinance (EIAO)
and as such the statutory procedures under the EIAO need to be followed and an
environmental permit is required prior to the commencement of construction.
The AAHK first commissioned Meinhardt
Infrastructure and Environmental Ltd (know as Mouchel
Asia Limited at that time) in June 2001 to provide professional environmental
services in respect of assessing Tuen Mun Area 38 as the location for a PAFF and to proceed with
obtaining an Environmental Permit for the PAFF based on the EIA Study Brief No.
ESB-072/2001 received from the Environmental Protection Department (EPD). An EIA of the PAFF facility (EIAO Register
Number AEIAR-062-2002), based upon the layout detailed in Figure
1.2a, was
prepared in accordance with EIA Study Brief issued by the EPD in May 2001 and
submitted under the EIAO in May 2002 and subsequently Environmental Permit EP-139/2002 was granted on the 28th
August 2002.
However, the decision by EPD to grant the
Environmental Permit was subject to a Judicial Review, with further details
provided in Section 1.1.5 of the EIA Report.
The Judicial Review sided in the favour of the DEP, as did the
subsequent Judgement from the Court of Appeal from the High Court for Judicial
Review in March 2005. However, the DEP’s decision to grant the EP was quashed by the Judgement
of the Court of Final Appeal of July 2006.

As noted above, while the previous EIA Study (April
2002) was undertaken based upon the project layout detailed in Figure
1.2a, the need
for minor changes to the detailed layout of the site and the site boundary were
identified and consequently an Application for Variation to the Environmental
Permit (VEP) (VEP-133/2004) was
submitted to the Director of Environmental Protection (DEP) for approval of the
following changes:
·
A
change in the detailed layout of the site, in particular the designed height
and dimension of the tanks. The height
of the tanks has been reduced in compliance with FSD’s
specific requirements, where as the diameters of some tanks have been increased
as a consequence of compliance with FSD’s tanks
height reduction requirements in order to maintain the designed fuel storage
capacity of the tank farm.
·
To shift
the whole site by 10 metres to the southeast to accommodate Land’s Department’s
commitment of land extension to Shiu Wing Steel.
The variation to the EP (EP-139/2002/A) was granted by EPD in February 2004. Details of the revised layout are provided in
Section 2, Project Description and Figure
1.2b. In addition, the phasing of the tanks has
changed with 8 (eight) to be constructed initially as shown in Figure
1.2c. Indicative cross sections between the tanks
and the lot boundaries with Shiu Wing Steel and the EcoPark are provided in Figures
1.2d and 1.2e respectively with the location of the
cross-sections shown in Figure 1.2c.
The revised EIA (EIAO Register Number AEIAR-107/2007)
for the project recommended comprehensive Environmental Monitoring and Audit
requirements to be undertaken during the construction and operational stages of
the project. This Report constitutes the
Environmental Monitoring and Audit (EM&A) Manual for the proposed Permanent
Aviation Fuel Facility, providing details of the EM&A recommendations and
constitutes an update from the previous EM&A Manual (May 2006).
The revised EIA was submitted in 2007 and the
environmental permit (EP-262/2007) was granted in May 2007. EP-262/2007 has been amended to EP-262/2007/A and issued by the EPD on 30 November 2007. A further Variation to the Environmental
Permit has been approved to allow dredging works to continue until March
2008. As such, EP-262/2007/A has been amended to EP-262/2007/B and issued by the EPD on 27 February 2008.
ERM-Hong Kong, Ltd (ERM) has been commissioned by
LCAL to implement an environmental monitoring and auditing programme for the
Project. In relation to the anticipated
environmental impacts of the Project, respective mitigation measures and
environmental monitoring and audit requirements have been recommended in the
EIA reports. This Environmental
Monitoring and Audit (EM&A) Manual has been prepared in supplement of the
EIA reports to provide details of the EM&A requirements during the Project.
According to Condition
2.5 of the EP (EP-262/2007), an updated EM&A Manual shall been prepared
and submit to the Director of Environmental Protection (DEP) no later than one
month before the commencement of construction of the sub-sea pipelines of the
Project. This EM&A Manual has been
prepared based on the EM&A Manual (February 2007) submitted with the
Revised EIA Report (2007) and the EM&A Manual (May 2006) in operation prior
to suspension of construction works and has been reviewed and updated in regard
to the latest available information (as detailed above). A summary of the changes made is presented in
Table 1.1 below.

The Hong Kong SAR Government’s applicable environmental regulations for
noise, air quality, ecology, water quality, landscape and visual resources,
waste management and heritage protection, the Hong Kong Planning Standards and
Guidelines and recommendations in the Permanent Aviation Fuel Facility EIA
Report have served as guidance documents in the preparation of this Manual. This EM&A Manual fulfills the requirements
of the EIA Study Brief, Clause 3.3.15, and follows the approach recommended in EPD’s Generic EM&A Manual, Annex 21 of the Technical
Memorandum on the EIA Process and EM&A Guidelines for Development Projects
in
It is proposed that the PAFF
will be located at an undeveloped reclaimed shoreline site at Tuen Mun Area 38. It will consist of the following major
elements:
·
a jetty with two berths, which together will accommodate
a full range of vessels from 10,000 to 80,000 dwt vessels;
·
a tank farm with gross aviation fuel tankage capacity of 264,000m3 on commissioning and an ultimate tankage of
about 388,000m3 as well as pumps
and associated facilities;
·
on site operational facilities including offices; and,
·
500mm diameter twin subsea pipelines to transfer the
fuel to the aviation fuel system at the airport.
The planning, design and
construction of the project is programmed to take in the region of 3-4 years,
with the commissioning date estimated to be in 2009.
The overall study area
showing the location of the proposed site and the proposed pipeline alignment
is provided in Figure 1.1.
While some construction works for the PAFF have been
undertaken from November 2005, they were suspended following the Judgement of
the Court of Final Appeal of July 2006.

The broad objective of this EM&A
Manual is to define the procedures of the EM&A programme for monitoring the
environmental performance of the Permanent Aviation Fuel Facility project
during design, construction and implementation.
The manual
provides details of the environmental monitoring and audit requirements arising
from the EIA for water quality, noise, air, water quality, ecology, landscape
and visual, waste, land contamination, hazard to life and fuel spill risks and
cultural heritage. The purposes of the defined EM&A programme are as
follows:
·
to
ensure the specified mitigation recommendations of the EIA are included in the
design of the project;
·
to
clarify and identify sources of pollution, impact and nuisance arising from the
works;
·
to
confirm compliance with legal, contract specifications and EIA study recommendations;
·
to
provide an early warning system for impact prevention; to provide a database of environmental
parameters against which to determine any short term or long term environmental
impacts;
·
to
propose timely, cost-effective and viable solutions to actual or potential
environmental issues;
·
to
monitor performance of the mitigation measures and to assess their
effectiveness and, whenever necessary, identify any further need for additional
measures; to verify the EIA predicted
impacts;
·
to
collate information and evidence for use in public, District Council and
Government consultation; and
·
to
audit environmental performance.
EM&A
procedures are required during the design, construction and operational phases
of the project implementation and a summary of the requirements for each of the
environmental parameters is detailed in Table
1.4 below.

In this Section, the
various parties involved in the EM&A process are outlined. The structure of the organisations
responsible for implementing the EM&A programme and their key
responsibilities are presented. Figure 2.1 shows the
organisation structure for the Project.
The roles and
responsibilities of the various parties involved in the construction phase
EM&A process are outlined in the following sections. The duties and responsibilities of respective
parties are as described below.
For the purpose
of this EM&A Manual, the Airport Authority Hong Kong appointed Franchisee
is referred to as the “Employer” and the Project “Engineer” defined as the
Franchisee’s Site Representative (FSR), who will be responsible for the
supervision of the construction of the Project.
The
specifications for certain risk and spill control mitigation measures will be
required to be designed during the detailed design phase of the project. These items will include:
·
land
and marine spill response plan; pipeline leak detection and automatic shut-off
system; pipeline rock armour protection;
·
tank
high level shut-off;
·
tank bunding; tank leak drainage isolation and containment
system;
·
on-site
fire fighting equipment;
·
jetty
protection; and,
·
emergency
shut down valves for fuel delivery.
In addition, the
landscape design drawings and dolphin exclusion zone during dredging will
require specifications during the detailed design and could require the input
of specialists such as landscape architect and trained biologist.
In respect of the
design phase EM&A, the Engineer commissioned to undertake the Design and
Construction Assignment will be required to designate an auditor(s) to
undertake an environmental audit of the design of these measures in order to
ensure that the recommendations of the EIA have been fully and properly
specified. Detailed design of the
facility will extend into the construction period and as such EM&A for the
Design Phase refers to audit of the design as and when it is completed and not
necessary pre-construction. As such, the design audit shall be undertaken as
and when the relevant design aspects are produced and the Engineer will be
required to prepare a Design Audit Report at the end of the detailed design
which will confirm that the requirements of the EIA have been fully taken into
account in the project design. The
Engineer shall use suitably qualified staff to undertake the audit
requirements. A flow chart of the design
phase EM&A procedures is shown in Figure 2.2.
During the
construction phase of the project, an Environmental Team Leader (ETL) shall
ensure the Contractor’s compliance with the project’s environmental performance
requirements during construction and undertake the post construction EM&A
works and his responsibilities will include field measurements, sampling,
analysis of monitoring results, reporting and auditing. The ETL shall be approved by the ER and shall
be competent and shall have at least 7 years relevant environmental monitoring
and audit experience on projects of a similar scale and nature.
The ETL will
require suitably qualified support staff (the Environmental Team, (ET)) to
carrying out the EM&A programme.
Both the ETL and members of the ET shall be independent and shall not be
in any way connected to the Contractor’s company. Due to the specialist nature of some of the
EM&A works required for this project, the ET should comprise professionals
proficient to undertake the tasks involved.
Thus, the ET should include personnel experienced in noise, dust and
water quality monitoring and supervision of waste management.
The qualified
specialists in dolphin survey monitoring, with a minimum of 2 years post
qualification experience and two years practical experience in this field, will
be required as part of the ET to undertake the post construction abundance
monitoring of the dolphins prior to the operation of the facility. In addition, a Registered Landscape
Architect, as defined by the Landscape Architect’s Registration Board, will be
required on the ET to monitor and audit the landscaping installation works.
A qualified marine
archaeologist to the satisfaction of the AMO will be required to undertake the
audit of the potential marine archaeological resources as defined by the Marine
Archaeological Investigation. The qualified archaeologist should possess
professional qualifications such as an academic degree in archaeology, relevant
experience in marine archaeology at a supervision level and be familiar with
the archaeology of Hong Kong and/or
In addition to the
ETL and ET, an Independent Environmental Checker (IEC) shall be employed to
advise the ER on environmental issues related to the project. The role of the IEC shall be independent from
the management of construction works, but the IEC shall be empowered to audit
the environmental performance of the construction activities and operational
mitigation. The IEC shall have project
management experience in addition to the requirements of the ETL specified in Section 2.4 and the appointment of the
ICE will be subject to the approval of the FSR.
A Community
Liaison Group will also be set up as required by the Environmental Permit.
The operational
EM&A works will be the responsibility of the Contractor and will be
undertaken in parallel to the maintenance period after the completion of
construction. The future, operational
stage, EIA review at the planning stage for the future tanks should be
undertaken by an environmental specialist appointed by the Franchisee at that
time.
The Contractor
will:
·
employ
an Environmental Team (ET) to undertake monitoring, laboratory analysis and
reporting of environmental monitoring and audit data;
·
provide
assistance to the ET in carrying out monitoring;

To
clarify the terminology for impact monitoring and audit, key definitions are
specified below and are used throughout this Manual.
Monitoring
refers to the systematic collection of data through a series of repetitive
measurements. The stages of monitoring are defined in this document as follows:
·
Baseline
Monitoring refers to the measurement of parameters, such as noise and air
quality impact parameters, during a representative pre-project period for the
purpose of determining the nature and ranges of natural variation and to
establish, where appropriate, the nature of change; and,
·
Impact
Monitoring involves the measurement of environmental impact parameters, such as
noise and air quality, during Project construction and implementation so as to
detect changes in these parameters which can be attributed to the Project.
Audit
is a term that infers the verification of a practice and certification of data.
The types of audit are defined below:
(i)
Compliance
audit is defined as follows:
·
the
process of verification that all or selected parameters measured by a noise or
air quality impact monitoring programme or levels of an operation are in
compliance with regulatory requirements and internal policies and standards;
and,
·
the
determination of the degree and scope of any necessary remediation in the event
of exceedance of compliance
(ii)
Post
Project Audit is carried out after the implementation and commissioning of a
Project
For
the purpose of noise, air and water quality impact monitoring and audit, the
Action and Limit Levels are defined as follows:
·
The
Action Level is the level defined in which there is an indication of a
deteriorating ambient level for which a typical response could be an increase
in the monitoring frequency; and,
·
The
Limit Level is the level beyond the appropriate remedial pollution control
ordinances, noise and air quality impact objectives or Hong Kong Planning
Standards and Guidelines established by the EPD for a particular project, such
that the works should not proceed without appropriate remedial action,
including a critical review of plant and work methods.
In this section,
the general requirements of the EM&A programme for the Project are
presented with reference to the relevant findings from the EIA Report that have
formed the basis of the scope and content of the programme.
The environmental
issues, which were identified during the EIA process and are associated with
the construction phase of the Project will be addressed through the monitoring
and controls specified in this EM&A Manual and in the construction
contracts.
During the
construction phases of the Project, air quality, noise quality, water quality,
ecology, landscape and visual, waste and cultural heritage will be subject to
EM&A, with environmental monitoring being undertaken for water quality and
marine ecology as determined in the EIA.
The monitoring of
the effectiveness of the mitigation measures will be achieved through the
environmental monitoring programme as well as through site inspections. The inspections will include within their
scope, mechanisms to review and assess the Contractor’s environmental
performance, ensuring that the recommended mitigation measures have been
properly implemented, and that the timely resolution of received complaints are
managed and controlled in a manner consistent with the recommendations of the
EIA Report.
The environmental
monitoring work throughout the Project period will be carried out in accordance
with this EM&A and reported by the ET.
Monitoring works will comprise of quantitative assessment of physical
parameters such as water quality and marine ecology impacts which also form an
important part of the whole monitoring programme. The monitoring programme will be conducted at
the chosen representative sensitive receivers in the vicinity of the
construction site.
Action and Limit
(A/L) Levels are defined levels of impact recorded by the environmental
monitoring activities which represent levels at which a prescribed response is
required. These Levels are quantitatively
defined later in the relevant sections of this manual and described in
principle below:
·
Action
Limits: beyond which
there is a clear indication of a deteriorating ambient environment for which
appropriate remedial actions are likely to be necessary to prevent
environmental quality from falling outside the Limit Levels, which would be
unacceptable; and
·
Limit
Levels: statutory and/or
agreed contract limits stipulated in the relevant pollution control ordinances,
HKPSG or Environmental Quality Objectives established by the EPD. If these are exceeded, works will not proceed
without appropriate remedial action, including a critical review of plant and
working methods.
The purpose of
the Event and Action Plans (EAPs) is to provide, in
association with the monitoring and audit activities, procedures for ensuring
that if any significant environmental incident (either accidental or through
inadequate implementation of mitigation measures on the part of the Contractor)
does occur, the cause will be quickly identified and remediated, and the risk
of a similar event recurring is reduced.
This also applies to the exceedances of A/L
criteria identified in the EM&A programme.
In addition to
monitoring water quality and marine ecology as a means of assessing the ongoing
performance of the Contractor, the ET will undertake weekly site inspections
and audits of on-site practices and procedures.
The primary objective of the inspection and audit programme will be to
assess the effectiveness of the environmental controls established by the
Contractor and the implementation of the environmental mitigation measures
recommended in the EIA Report.
Whilst the audit
and inspection programme will undoubtedly complement the monitoring activity
with regard to the effectiveness of controlling impacts to water quality and
marine ecology, the criteria against which the audits will be undertaken will
be derived from the Clauses within the Contract Documents which seek to enforce
the recommendations of the EIA Report and the established management systems.
The findings of
site inspections and audits will be made known to the Contractor at the time of
the inspection to enable the rapid resolution of identified
non-compliances. Non-compliances, and
the corrective actions undertaken, will also be reported in the monthly
EM&A Reports.
Section 11 of this Manual presents details of the
scope and frequency of on-site inspections and defines the range of issues that
the audit protocols will be designed to address.
Enquiries,
complaints and requests for information may occur from a wide range of
individuals and organisations including members of the public, Government departments,
the press and television media and community groups.
All enquiries
concerning the environmental effects of the construction works, irrespective of
how they are received, will be reported to the Engineer and via the Contractor
directed to the ET which will set up procedures for the handling, investigation
and storage of such information.
In all cases the
complainant will be notified of the findings, and audit procedures will be put
in place to minimise the change of reoccurrence of the problem, should there be
one.
The following
submissions will required to be certified by the ET Leader and verified by the
IEC:
·
Baseline monitoring report
·
EM&A report (monthly, quarterly and final)
·
Waste
management plan
·
Landscape
plan
·
Design
plan to prevent risk to life, fuel
spillage, land contamination and water quality impact during operation
The monthly
reports will be prepared and submitted within two weeks of the end of each
calendar month.
The
cessation of EM&A programme is subject to the satisfactory completion of
the EM&A Final Review Report, agreement with the IEC and approval from EPD.
The potential for
SO2, NO2 and smoke emitted from the diesel-powered equipment during the construction
phase is expected to be minimal as the number of such plant required on-site
will be limited and under normal operation, equipment with proper maintenance
is unlikely to cause significant dark smoke emissions. Notwithstanding, plant
should be regularly maintained to minimise emissions.
The principal
source of air pollution during the construction phase will be dust from exposed
site areas, stockpiling, movement of vehicles along unpaved roads, excavation
and handling of construction materials, all of which will be particularly
relevant during the dry seasons.
However, the
closest residential sensitive receivers to the proposed PAFF are low rise
residential properties at Lung Kwu Tan and high rise
residential blocks at Melody Gardens in Tuen Mun, both some 2 and 3km away respectively. In addition, the sensitive receivers are
shielded from the PAFF site by topography.
There is also a planned Holiday Camp to the east along
Air quality is regulated through Annex 4
of the Technical Memorandum on EIA Process (TMEIA) which specifies compliance
with the Air Quality Objectives (AQO) and other standards established under the
Air Pollution Control Ordinance (APCO).
The APCO and all regulations specified by this Ordinance, for example
the Air Pollution Control (Construction Dust) Regulation, should be complied
with. The 24 hour Total Suspended
Particulates (TSP) AQO is 260 μg/m3.
In addition to the Air Quality Objectives,
the TMEIA stipulates a criteria to meet the hourly TSP concentration of 500
μg/m3 measured at 298°K (25şC) and 101.325 kPa
(1 atmosphere) for construction dust impact assessment.
The Air Pollution Control (Construction
Dust) Regulation defines notifiable and regulatory
works for achieving the purpose of dust control for a number of
activities. The Regulation requires any notifiable work shall require advance notice to EPD. It
also requires the contractor to ensure that the notifiable
work and regulatory work will be carried out in accordance to the Schedule of
the Regulation. Dust control and suppression measures are provided in the
Schedule. Notifiable
works are site formation; reclamation; demolition, foundation and
superstructure construction for buildings; and road construction. Regulatory
works are building renovation, road opening and resurfacing, slope
stabilisation, and other activities including stockpiling, dusty material
handling, excavation, concrete production, etc.
This project is expected to include both notifiable
and regulatory works.
The proposed PAFF is classed as a
specified process under Part IV of the APCO and falls within the category
“Organic Chemical Works” described in Schedule 1 of the Ordinance. The following relevant clause relates to the
tank farm of the proposed PAFF:
“Works, not being a chemical process
described in any other process of the following kinds in which:
(b) any organic liquids, including liquid fuel
are stored in tanks having an installed capacity exceeding 100m3.”
Dust predictions are adjacent sensitive receivers
show that some exceedances of both the 1-hour (500
µg/m3) and 24-hour (260 µg/m3) criteria could arise at Shiu Wing Steel and the EcoPark. As such twice daily watering of the site and
watering of the construction area every 1.5 hours in the vicinity of SR3c
during the works of site formation, stock piling, dusty material handling and
excavation has been recommended. Also,
in accordance with the Air Pollution Control (Construction Dust) Regulation,
the Contractor will be required to ensure that dust control measures stipulated
in the Regulation should be implemented to control dust emissions. Based upon this, the following dust control
measures are recommended. These measures
are also summarised in the Environmental Mitigation Implementation Schedules in
Annex B.
·
watering
of the construction area every 1.5 hours in the vicinity of SR1, SR3a, SR3c and
SR3d during site formation, stock piling, dusty material handling and
excavation works;
·
the
Contractor shall, to the satisfaction of EPD, install effective dust
suppression measures and take such other measures as may be necessary to ensure
that at the site boundary, dust levels are kept to acceptable levels;
·
the
Contractor shall not burn debris or other materials on the works areas;
·
provide
site hoarding not less than 2.4m at site boundary;
·
in hot,
dry or windy weather, a watering programme shall maintain all exposed road
surfaces and dust sources wet;
·
dust
creating activities shall be reprogrammed to avoid periods of high winds;
·
where
breaking of oversize rock/concrete is required, watering shall be implemented
to control dust. Water spray shall be
used in dry conditions during the handling of fill material at the site and at
active cuts, excavation and fill sites where dust is likely to be created;
·
open
dropping heights for excavated materials shall be controlled to a maximum
height of 2m to minimise the fugitive dust arising from unloading;
·
during
transportation by truck, materials shall not be loaded to a level higher than
the side and tail boards, and shall be dampened or covered before transport. Materials having the potential to create dust
shall not be loaded to a level higher than the side and tail boards, and shall
be covered by a clean tarpaulin. The
tarpaulin shall be properly secured and shall extend at least 300mm over the
edges of the side and tail boards;
·
no
earth, mud, debris, dust and the like shall be deposited on public roads. Wheel washing facility shall be usable prior
to any earthworks excavation activity on the site;
·
areas
of exposed soil shall be minimised to areas in which works have been completed
shall be restored as soon as is practicable;
·
all
stockpiles of aggregate or spoil shall be enclosed or covered and water applied
in dry or windy conditions; and,
·
provide
awareness training in the need to minimise dust.
If the above measures are not sufficient to manage
dust generation, upon the advice of the ETL, the Contractor shall liaise with
the ET regarding other mitigation measures and consult the IEC for their
effectiveness, and then propose these measures to the FSR for approval prior to
the implementation of the measures
EM&A is recommended during the construction phase
only and the effective management of dust arisings
during the construction phase will be monitored through the site audit
programme.
The aims of the dust audit are:
·
to
ensure that appropriate measures, including but not limited to those measures
stipulated above, as being implemented with the aim to minimise and control
dust arisings from the site; and,
·
to
encourage good site practices.
The Contractor shall be required to pay attention to
the environmental standard and guidelines detailed in Section 4 and carry out appropriate dust management measures.
During the site inspections and the document review
procedures as mentioned in Chapter 11 of this Manual, the ET shall pay special
attention to the issues relating to dust management and check whether the
Contractor has followed the relevant contract specifications and the procedures
specified under the laws of
The Contractor’s dust management practices should be

Should any ad hoc spot check monitoring be required
of the Total Suspended Particulates (TSP) levels, this shall comprise
monitoring of 1-hour TSP levels measured by direct reading methods. Any ad hoc monitoring shall be carried out by
the Environmental Team Leader (ETL) (see Section 1) to ensure that construction
works are not generating dust which exceeds the acceptable level.
Other relevant data including weather conditions and
any other special phenomena and work progress of the concerned site shall be
recorded in detail by the ETL. A sample
data sheet is shown in Annex C.
The Contractor is responsible for provision of the
monitoring equipment if required and shall ensure that direct reading samplers
with an appropriate calibration kit are available for carrying out ad hoc
measurements if required. Calibration of dust monitoring equipment shall be
conducted by the ETL in accordance with the manufacturer’s
recommendations. The calibration data
shall be properly documented for future reference by concerned parties, such as
the IEC.
Wind data monitoring equipment shall also be provided
for logging wind speed and wind direction near to the dust monitoring locations
if monitoring is required. The equipment
installation location shall be proposed by the Contractor in consultation with
the ETL and agreed with the FSR, in consultation with the IEC. For installation and operation of wind data
monitoring equipment, the following points shall be observed.
·
the
wind sensors should be installed on masts at an elevated level 10 m above
ground so that they are clear of obstructions or turbulence caused by the
buildings;
·
the
wind data should be captured by a data logger to be down-loaded for processing
at least once a month;
·
the
wind data monitoring equipment should be re-calibrated at least once every six
months; and,
·
wind
direction should be divided into 16 sectors of 22.5 degrees each.
In exceptional situations, the ETL may propose
alternative methods to obtain representative wind data upon approval from the
FSR and agreement from the IEC.
When selecting sites for ad hoc monitoring, the
following preferred locations and factors shall be considered:
·
the
site boundary or locations close to the major dust emission source; and,
·
the
prevailing meteorological conditions.
The ETL shall agree with the FSR, in consultation
with the IEC, the position of the ad hoc monitoring.
Powered mechanical equipment will be used
to form the tank farm, jetty and lay the pipeline for the PAFF. However, the Tuen Mun Area 38 site is located on newly formed reclaimed land
in an area zoned for industrial use. The
existing land adjacent to the site is occupied by the cement plant and Shui Wing Steel Mill, with Castle Peak Power Station
further to the west. To the east, a
further lot of reclaimed land is proposed for use as an EcoPark,
and this is bordered by a sea area earmarked for formation in the near
future. The River Trade Terminal is
located further down the coast. The
alignment of the pipeline passes through open sea away from the land. None of
these are classed as noise sensitive receivers.
The closest noise sensitive receivers to
the proposed PAFF are low rise residential properties at Lung Kwu Tan and high rise residential blocks at Butterfly Beach
in Tuen Mun, both about 2km
and 3km away respectively. In addition,
these sensitive receivers are shielded from the PAFF site by topography and
there will be no line of sight to the facility. There is also a planned Holiday Camp to the
east along
Non restricted hours include the daytime hours on
working days which are not a Sunday or a public holiday between 07:00-19:00.
The noise generated by the construction of the Project during the
non-restricted daytime hours will be assessed with reference to Table 1B of
Annex 5 of the TMEIA. 4
If construction works during restricted hours are
specified in the construction programme or percussive piling is to be
undertaken, a Construction Noise Permit (CNP) will be required for the works
and the noise impacts will be assessed to ensure compliance with the relevant
Noise Control Ordinance (NCO) noise limits as specified in Annex 5 of the
TMEIA. Once applied for, the CNP will be
assessed by the Noise Control Authority based upon the contemporary situation
at the time of the application.
An application for a CNP for percussive piling is
assessed in accordance with the Technical Memorandum on Noise from Percussive
Piling under the NCO.
The CNP may contain permitted hours of operation as a
condition with reference to the predicted noise levels at noise sensitive
receivers. However, it is not
anticipated that percussive piling works will be required during the
construction of this project.
The NCO construction noise limits during restricted
hours are determined with reference to the type of area within which a Noise
Sensitive Receiver (NSR) is located. For
village and low-density residential areas not affected by noise, an Area
Sensitivity Rating (ASR) of ‘A’ is applied, while a low-density residential
areas in which traffic noise is noticeable but not dominant, an ASR of ‘B’ is
employed. For a similar area in which
noise from a major road is readily noticeable and dominates the noise
environment, an ASR of ‘C’ is applied.
The definition of a major road is provided in the Technical Memorandum
on Noise from Construction Work Other than Percussive Piling. The construction
noise criteria for each NSR are applied to the noise arising from operation of
construction equipment.
There are no sensitive receivers within designated
300m of the proposed site and works, with the closest being the proposed
Holiday Camp some 550m away and other sensitive receivers are about 2km
away. As such significant noise impacts
during the construction phase are not predicted. Notwithstanding, measures to
minimise noise levels as far as possible are recommended as follows. As no
sensitive receivers will be affected by the project, the mitigation measures
are advisory in nature only.
·
use
quiet equipment with suitable noise levels and labels;
·
regular
maintenance of equipment;
·
ensure
noise attenuation devices are fitted to plant and equipment such as:
·
fitting
more efficient exhaust sound reduction equipment and ensuring the Manufacturers’
enclosure panels are kept closed on dump trucks, lorries, excavators and
cranes;
·
fitting
suitably designed muffler or sound reduction equipment and using dampened bit
to eliminate ringing on breakers; and,
·
ensure
all leaks in air lines are sealed on all pneumatic equipment.
·
use
temporary noise barriers where applicable;
·
restrict
or modify working hours to minimise high noise activities;
·
provide
awareness training in the need to minimise noise; and,
·
proper
planning of work area; and good site
practice to limit noise emissions at source.
If additional measures are deemed necessary by the
ETL, the Contractor shall liaise with the ETL regarding other mitigation
measures and consult the IEC for their effectiveness, and then propose these
measures to the ER for approval prior to the implementation of the measures.
Management of noise during the construction phase
will be monitored through the site audit programme.
The
aims of the noise audit are:
·
to ensure
that appropriate measures, including but not limited to those measures
stipulated above, as being implemented with the aim to minimise and control
noise from the site; and,
·
to
encourage good site practices.
The
Contractor shall be required to pay attention to the environmental standard and
guidelines detailed in Section 5.2
and carry out appropriate noise mitigation measures.
During
the site inspections and the document review procedures as mentioned in Chapter
11 of this Manual, the ETL shall pay special attention to the issues relating
to noise mitigation and check whether the Contractor has followed the relevant
contract specifications and the procedures specified under the laws of
The
action level for construction noise is defined in Table 5.1. Should non-compliance of the criteria occur, the ETL,
the IEC, the ER and the Contractor shall undertake their specified actions in
accordance with the Action Plan shown in Table
5.2.

0700
– 1900 hrs on normal weekdays |
When
one documented complaint is received |
Should
any ad hoc noise monitoring be required in the even of a complaint, the construction
noise level shall be monitored by the ET and shall be measured in terms of the
A-weighted equivalent continuous sound pressure level (Leq).
Leq (30 min) shall be used as the monitoring
parameter for the time period between 0700-1900 hours on normal weekdays. In respect of all other time periods, Leq(5 min) shall be employed for comparison with the Noise
Control Ordinance criteria. A sample data record sheet is shown in Annex C for reference.
As
referred to in the Technical Memorandum (TM) issued under the Noise Control
Ordinance (NCO), sound level meters in compliance with the International Electrotechnical Commission Publications 651: 1979 (Type 1)
and 804: 1985 (Type 1) specifications shall be used for carrying out any noise
monitoring.
Immediately
prior to and following each noise measurement the accuracy of the sound level
meter shall be checked using an acoustic calibrator generating a known sound
pressure level at a known frequency.
Measurements may be accepted as valid only if the calibration level from
before and after the noise measurement agree to within 1.0dB.
Noise
measurements shall not be made in fog, rain, wind with a steady speed exceeding
5m/s or wind with gusts exceeding 10m/s.
The wind speed shall be checked with a portable wind speed meter capable
of measuring the wind speed in m/s. The
Contractor shall ensure that noise measuring equipment and associated
instrumentation are available for carrying out any ad hoc monitoring if required.
The
locations for noise monitoring, if required shall be proposed by the Contractor
in consultation with the ETL and verified with the Franchisee’s Site
Representative (FSR), the IEC and Environmental Protection Department
(DEP).
The
monitoring station shall normally be at a point 1m from the exterior of a
building facade or in the case the measurement is not being carried out at a
building, be at a position 1.2m above the ground.
For
reference, a correction of +3dB(A) shall be made to the free field
measurements. Noise levels shall be
corrected in accordance with Section 2.10, 2.11 and 2.13 of the “Technical
Memorandum on Noise From Construction Works Other Than Percussive Piling”. The ETL shall agree with the IEC on the
monitoring position and the corrections adopted prior to the commencement of
the works.

In accordance with the recommendations of the EIA and
conditions of approval from Country and Marine Parks Authority (CMPA), water
quality EM&A is required when construction works are being undertaken
within 1000m of the Lung Kwu Chau and
Sampling for water quality will be conducted for both
standard water quality parameters as well as Persistant
Organic Pollutants (POPs). Due to the different schedules associated
with each monitoring programme, monitoring for water quality parameters are
discussed in Section 6.2.1 with
monitoring of POPs in Section 6.2.2.
In accordance with the recommendations of the EIA,
construction phase water quality EM&A is required when marine construction
works are being undertaken within 1000m of the Lung Kwu
Chau and
Baseline measurements shall be undertaken for a
period of one week prior to construction on both flood and ebb tides. The baseline data shall be reviewed to
identify any pre-project variability in the dataset and to confirm the suitability
of the control stations to represent conditions at the impact stations in the
absence of any construction activity associated with the project.
Concurrently with the water quality parameter
measurements, associated data shall also be recorded, including the monitoring
location, time, water depth, water temperature, salinity, pH, DO saturation,
weather conditions, sea conditions and tidal stage. Observations on any special
phenomena and work underway at the construction site at the time of sampling
shall also be recorded. Water
temperature, salinity, pH and DO saturation shall be measured in-situ using direct reading
instrumentation. A sample monitoring
record sheet is shown in Annex C.
In addition, the Franchisee shall undertake some
routine monitoring of water quality in the vicinity of the PAFF site during the
operation phase to check the effectiveness of the proposed precautionary
measures implemented for on-site spill control.
The details of the monitoring to be undertaken, including the parameters,
frequency and monitoring locations, shall be prepared by the Franchisee as part
of the PAFF Operations Manual and the details will be agreed with the relevant
authorities prior to the commencement of operation of the PAFF. However, the monitoring should include but
not be limited to the parameters of TPH and PAH and reference should be made to
the existing monitoring programme undertaken for the fuel tank farm on the HKIA
platform. As such, the details of this
monitoring are not specified in this Manual.
For water quality monitoring, the following equipment
will be supplied and used by the Contractor:
·
Dissolved
Oxygen and Temperature Measuring Equipment
The
instrument shall be a portable, weatherproof dissolved oxygen measuring
instrument connected with cable and use a DC power source. It shall be capable
of measuring:-
-
a
dissolved oxygen level in the range of 0-20 mg/l and 0-200% saturation; and,
-
a
temperature of 0-45 degree Celsius
It shall have a membrane electrode with automatic
temperature compensation complete with a cable (e.g. YSI model 59 meter, YSI
5739 probe, YSI 5795A submersible stirrer with reel and cable or an approved
similar instrument). Sufficient stocks of spare electrodes and cables shall be
available for replacement where necessary.
Should salinity compensation not be
integrated in the DO equipment, in-situ
salinity shall be measured to calibrate the DO equipment prior to each DO
measurement.
·
Turbidity
Measurement Equipment
The instrument shall be a portable, weatherproof
turbidity-measuring instrument complete with comprehensive operation manual.
The equipment shall use a DC power source. It shall have a photoelectric sensor
capable of measuring turbidity between 0-1000 NTU and be connected with a cable
(e.g. Hach model 2100P or an approved similar
instrument).
·
Salinity
Measurement Instrument
A portable salinometer
capable of measuring salinity in the range of 0-40 ppt
shall be provided for measuring salinity and, if necessary, setting salinity compensation
on the Dissolved Oxygen Meter.
·
Suspended Solid Measurement
Equipment
The
equipment for measuring suspended solids shall be provided as follows:
-
A water sampler comprising a transparent
PVC cylinder with a capacity of not less than 2 litres (e.g. Kahlsico Water Sampler or an approved similar instrument)
and which can be effectively sealed with latex cups at both ends. The sampler
shall have a positive latching system to keep it open and prevent premature
closure until released by a messenger when the sampler is at the selected water
depth; and,
-
Water samples for suspended solids
measurement shall be collected in high density polythene bottles, packed in ice
(cooled to 40C without being frozen) and delivered to the laboratory
as soon as possible after collection.
·
Water
Depth Gauge
A portable, battery-operated echo sounder
shall be used for the determination of water depth at each designated
monitoring station. This unit can either
be handheld or affixed to the bottom of the work boat, if the same vessel is to
be used throughout the monitoring programme.
·
pH
Measuring Equipment
A portable pH meter capable of measuring a
range between 0.0 and 14.0 shall be provided to measure pH under the specified
conditions (eg. Orion Model 250A or an approved
similar instrument).
·
Positioning
Device
A hand-held or boat-fixed type
differential Global Positioning System (dGPS) or
other equivalent instrument of similar accuracy shall be provided and used
during monitoring to ensure the monitoring vessel is at the correct location
before taking measurements. Marine anchors shall not be used when sampling the
impact stations within or on the boundaries of the marine park.
·
Calibration
of Equipment
All in-situ
monitoring instrument shall be checked, calibrated and certified by a
laboratory accredited under HOKLAS or any other international accreditation
scheme before use, and subsequently re-calibrated at 3 monthly intervals
throughout all stages of the water quality monitoring. Responses of sensors and
electrodes shall be checked with certified standard solutions before each use.
Wet bulb calibration for the DO meter shall be carried out before measurement
at each monitoring location.
For the on site calibration of field
equipment, the BS 1427:1993, "Guide
to Field and on-site test methods for the analysis of waters" shall be
followed.
·
Backup
Equipment
Sufficient stocks of spare parts shall be
maintained for replacements when necessary.
Back-up monitoring equipment shall also be available so that monitoring
can proceed uninterrupted even when some equipment is under maintenance,
calibration, etc.
Analysis of suspended
solids shall be carried out in a HOKLAS or other international accredited
laboratory. Water samples of about 500ml shall be collected at the monitoring
stations for carrying out the laboratory SS determination. The SS determination work shall start within
24 hours after collection of the water samples.
The SS determination shall follow TSS-SM25400 or equivalent methods
subject to approval of the DEP.
The limits of
detection for the in-situ and
laboratory measurements that shall be obtained are shown in Table 6.1.
