This Environmental Monitoring and Audit (EM&A)
Manual (“the Manual”) has been prepared by ERM-Hong Kong, Limited (ERM) on
behalf of Water Supplies Department (hereinafter referred to as WSD). The Manual is a supplementary document of the
Environmental Impact Assessment (EIA) Study of the construction and operation
of a desalination plant using Seawater Reverse Osmosis (SWRO) technology in Tseung Kwan O (TKO) Area 137 (hereafter referred to as the
Project).
The Manual has been prepared in accordance
with the EIA Study Brief (No. ESB-266/2013) and the Technical
Memorandum of the Environmental Impact Assessment Process (EIAO-TM). The purpose of the Manual is to provide information,
guidance and instruction to personnel charged with environmental duties and
those responsible for undertaking EM&A work during construction and
operation. It provides systematic
procedures for monitoring and auditing of potential environmental impacts that
may arise from the works.
This Manual contains the following
information:
·
Responsibilities of the Contractor(s),
Environmental Team (ET), and the Independent Environmental Checker (IEC) with
respect to the environmental monitoring and audit requirements during the
course of the project;
·
Project organisation;
·
Requirements with respect to the construction
and operational programme schedule and the necessary environmental monitoring
and audit programme to track the varying environmental impact;
·
Details of the methodologies to be adopted
including field, laboratory and analytical procedures, and details on quality
assurance and quality control programme;
·
Preliminary definition of Action and Limit
levels;
·
Establishment of Event and Action plans;
·
Requirements for reviewing pollution sources
and working procedures required in the event of exceedances of applicable
criteria and/or receive of complaints;
·
Requirements for presentation of
environmental monitoring and audit data and appropriate reporting procedures;
and
·
Requirements for review of EIA predictions
and the effectiveness of the mitigation measures/environmental management
systems and the EM&A programme.
For the purpose of this manual, the ET Leader (ETL), who will be
responsible for and in charge of the ET, will refer to the person delegated the
role of executing the EM&A requirements.
This Manual is considered to be a working document and should be
reviewed periodically and updated if necessary during the course of
implementing the Project.
The
proposed Tseung Kwan O desalination plant will
produce potable water with an initial capacity of 135 million liter per day (MLD),
expandable to an ultimate capacity of 270 Mld in the future to provide a
secure and alternative fresh water resources complying with the World Health
Organization (WHO) standards. The plant
will adopt the Seawater
Reverse Osmosis (SWRO) technology, which dominates the market due to its
reliability and progressive reduction in cost as the technology advances.
The following elements of the Project are
classified as Designated Projects under the Environmental
Impact Assessment Ordinance (Cap. 499)
(EIAO) and are addressed in this EIA Report:
·
Schedule
2, Part I, Item E.2 – Water treatment works with a capacity if more than
100,000 m3 per day.
·
Schedule
2, Part I, Item K.13 – A dangerous good godown with a
storage capacity exceeding 500 tonnes.
·
Schedule
2, Part I, Q.1 – Earthworks partly in an existing country park.
The location of the Project and the
associated works are shown in Figure 1.1.
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 Project during design, construction and
operation. The construction and
operational impacts arising from the implementation of the Project are
specified in the EIA Report. The EIA
Report also specifies mitigation measures and construction practices that may
be needed to confirm compliance with the environmental criteria. These mitigation measures and their
implementation requirements are presented in the Implementation Schedule of
Mitigation Measures (Annex A).
The main objectives of the EM&A programme are to:
·
provide a database of environmental parameters against which to
determine any short term or long term environmental impacts;
·
provide an early indication should any of the environmental control
measures or practices fail to achieve the acceptable standards;
·
confirm that the mitigation recommendations of the EIA are included in
the design of the project;
·
clarify and identify potential sources of pollution, impact and nuisance
arising from the works for the responsible parties;
·
confirm compliance with regulatory requirements, contract specifications
and EIA study recommendations;
·
confirm compliance of environmental designs during the design phase of
the Project with the specifications stated in the EIA Report and the EP;
·
monitor performance of the mitigation measures and to assess their
effectiveness;
·
take remedial action if unexpected issues or unacceptable impacts arise;
·
verify the environmental impacts predicted in the EIA; and
·
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 1.1.

This Manual is an evolving
document that should be updated to maintain its relevance as the Project
progresses. The primary focus for these
updates will be to ensure the impacts predicted and the recommended mitigation
measures remain consistent and appropriate to the manner in which the works are
to be carried out.
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, water quality, waste management, land
contamination, landscape and visual and landfill gas hazard will be subject to
EM&A, with environmental monitoring being undertaken for noise and water
quality as determined in the EIA.
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)’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.
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 Levels: 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.
In addition to monitoring; as
a means of assessing the ongoing performance of the Contractor(s), the ET will
undertake site inspections and audits of the compliance with stipulated
procedures and on-site practices. The
primary objective of the inspection and audit programme will be to assess the
effectiveness of the environmental controls established by the Contractor(s)
and the implementation of the environmental mitigation measures recommended in
the EIA Report. The IEC will undertake
site inspection and audit on as need basis to assess the performance of the
Contractor(s).
Whilst the audit and
inspection programme will complement the monitoring activity, 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 EM&A Manual.
The findings of site
inspections and audits will be made known to the Contractor(s) at the time of
the inspection to enable the rapid resolution of identified
non-conformities. Non-conformities, and
the corrective actions undertaken, will also be reported in the monthly
EM&A Reports.
Section 12 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 community
groups.
All enquiries concerning the environmental impacts of the Project,
irrespective of how they are received, should be reported to the Project
Proponent and IEC and directed to the Contractor and ET who should set up
procedures for handling, investigation and storage of such information. The following steps should be followed:
(a)
The ET Leader should
notify the IEC and ER of the nature of the enquiry.
(b)
An investigation should
be initiated to determine the validity of the complaint and to identify the
source(s) of the problem.
(c)
The ET Leader and the
Contractor should undertake the following steps, as necessary:
·
investigate and identify
source(s) of the problem;
·
if considered necessary
by Project Proponent following consultation with the IEC, undertake additional
monitoring to verify the existence and severity of the alleged complaint;
·
identify necessary remedial measures and implement as soon as possible;
·
if the complaint is transferred from EPD, submit interim report
to EPD on status of the complaint investigation and follow-up action within the
time frame assigned by EPD;
·
repeat the monitoring to
verify effectiveness of mitigation measures; and,
·
repeat review procedures to
identify further possible areas of improvement if the repeat monitoring results
continue to substantiate the complaint.
(d)
The outcome of the
investigation and the action taken will be documented on a complaint log (Annex B). A formal response to each complaint received
will be prepared by the Contractor(s) within five working days and submitted to
Project Proponent, in order to notify the concerned person(s) that action has
been taken. All enquiries/complaints
that trigger this process should be reported in the monthly EM&A reports,
which should include results of investigations undertaken by the ET Leader and
the Contractor, and details of the measures taken, and additional monitoring
results (if deemed necessary). It should
be noted that the receipt of complaint or enquiry should not be, in itself, a
sufficient reason to introduce additional mitigation measures.
During the complaint investigation work, the Contractor and ER
shall cooperate with the ET Leader in providing all necessary information and
assistance for completion of the investigation.
If mitigation measures are identified in the investigation, the
Contractor shall promptly carry out the mitigation. The ER shall ensure that the measures have
been carried out by the Contractor.
The EIA study concluded that no air sensitive receivers
(ASRs) will be affected by construction dust through the implementation of
mitigation measures to reduce dust levels.
During the operation phase, emissions will be controlled by integrated
measures, regular inspections and relevant emissions licenses. Emissions from construction or operation
phase are not predicted to yield concentrations that would lead to significant
air quality impacts at the ASRs.
Therefore, no air quality monitoring will be required for either the
construction or operation phase, aside from that required by specific emissions
licenses.
Regular site inspections and audits will be
carried out during the construction phase in order to confirm that the
mitigation measures are implemented and are working effectively. The Contractor(s) will be responsible for the
design and implementation of the mitigation measures which are presented in Annex A.
The mitigation
measures and general requirements, methodology and equipment for monitoring and
audit of noise impacts associated with the Project are described in this
section.
The ET should carry out the baseline noise
monitoring prior to the commencement of the major construction works. The baseline noise levels should be measured
for a continuous period of at least 14 consecutive days at a minimum logging
interval of 30 minutes during daytime between 0700 and 1900 hours. The Leq, L10 and L90 should be recorded
at the specified intervals. A schedule
for the baseline monitoring should be submitted to the IEC for approval before
the commencement of baseline monitoring.
There should not be any construction
activities in the vicinity of the monitoring stations during the baseline
monitoring. Any non-project related
construction activities in the vicinity of the monitoring stations during the
baseline monitoring should be noted and the source and location of such
activities should be recorded.
In exceptional cases, when baseline
monitoring data obtained are insufficient or questionable, the ET should liaise
with the IEC and EPD to agree on an appropriate set of data to be used as the
baseline reference.
The impact noise monitoring should be carried
out at all the designated monitoring stations when there are project-related
construction activities undertaken within a radius of 300m from the monitoring
stations. Monitoring of Leq(30min)
should be carried out at each station at 0700-1900 hours on normal weekdays at
a frequency of once a week when construction activities are underway. Any general construction work carried out
during restricted hours is controlled by Construction Noise Permit (CNP) under
the NCO.
In case of non-compliances with the
construction noise criteria, more frequent monitoring as specified in the Event
and Action Plan (Section 4.4) should
be carried out. This additional
monitoring should be continued until the recorded noise levels show that the non-compliance
is rectified or proved to be irrelevant to the project-related construction
activities.
As referred to in the Technical Memorandum (TM) issued under the 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 the 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 should be accepted as valid
only if the calibration level from before and after the noise measurement
agrees to within 1.0 dB.
Noise measurements should not be made in fog, rain, wind with a steady
speed exceeding 5 m s-1 or wind with gusts exceeding 10 m s-1. The wind speed shall be checked with a
portable wind speed meter capable of measuring the wind speed in m s1.
The ET is responsible for the provision of the monitoring equipment to
ensure that sufficient noise measuring equipment and associated instrumentation
are available for carrying out the baseline monitoring, regular impact
monitoring and ad hoc monitoring. All
the equipment and associated instrumentation shall be clearly labelled.
According to the environmental findings detailed in the EIA report, the
designated locations for the construction noise monitoring are listed in Table
4.1 and shown in Figure 4.1.

The status and location of the noise sensitive
receivers (NSRs) may change after this EM&A Manual has been issued. In such case, and if changes to the
monitoring locations are considered necessary, the ET should propose
alternative monitoring locations and seek the agreement from the IEC and EPD on
such proposal. When alternative
monitoring locations are proposed, they should be chosen based on the following
criteria:
(i)
The monitoring locations close to the major construction works
activities that are likely to have noise impacts;
(ii)
The monitoring close to the NSRs as defined in the EIAO-TM; and,
(iii) The assurance of the
minimal disturbance and working under a safe condition to the occupants during
the monitoring in the vicinity of the NSRs.
The monitoring
stations should normally be at a point 1m from the exterior of the facade of
the NSR and be at a position 1.2m above ground.
If there is a problem with access to the normal monitoring position, an
alternative position should be chosen, and a correction to the measurement
results should be made. For reference, a
correction of +3dB(A) should be made to the free-field
measurements. The ETL should agree with
the IEC and EPD on the alternative monitoring position and corrections
adopted. Once the positions for the
monitoring stations are chosen, the baseline and impact monitoring should be
carried out at the same positions.
The action and limit levels for construction noise are defined in Table
4.2. If non-compliance occurred,
actions as stated in Table 4.3 should be undertaken.
According to the EIA report, the construction activities would cause
noise exceedances at various NSRs and, therefore, appropriate mitigation
measures and good site practices are recommended. The Contractor should be responsible for the
design and implementation of these measures.
The Implementation Schedule of the mitigation measures is included in Annex A of this EM&A Manual.

Effluent from
desalination plant shall be collected at a suitable location after all
treatment process before discharge. The sampling
location should be agreed with WSD and EPD, and should fulfil the following
requirements:
·
Effluent
collected at the sampling location is representative to the effluent discharged
at the outfall diffuser
·
Sampling
works at the sampling location would not interfere with the desalination plant
operation
·
Sampling works at the sampling location would not induce safety hazard
(e.g. staff sampling effluent drops into the culvert)
The status and locations of water quality sensitive receivers and the
monitoring sites may change after issuing this Manual. If such cases exist, the ET shall propose
updated monitoring locations and seek approval from the ER, the IEC, and the
IEC.
When alternative monitoring locations are proposed, they shall be chosen
based on the following criteria:
·
at locations close to and preferably at the
boundary of the site activities as indicated in the EIA report, which are
likely to have water quality impacts;
·
close to the sensitive receptors which are directly
or likely to be affected;
·
for monitoring locations located in the
vicinity of the sensitive receptors, care should be taken to cause minimal
disturbance during monitoring; and
·
reference stations which are at locations
representative of the project site in its undisturbed condition.
Baseline conditions
for water quality shall be established and agreed with the IEC and the EPD
prior to the commencement of works. The
purpose of the baseline monitoring is to establish ambient conditions prior to
the commencement of the works and to demonstrate the suitability of the
proposed impact and control monitoring stations. The baseline conditions shall
normally be established by measuring the water quality parameters specified
above.
The measurements
shall be taken at all designated monitoring stations including control
stations, once per day for a minimum of 3 days per week for 4 weeks prior to
the commencement of the construction works.
Measurements shall be taken at each station at any time. The interval between two sets of monitoring
shall not be less than 36 hours.
No construction
activities shall be on-going in the vicinity of the stations during the
baseline monitoring. The ET shall be responsible for undertaking the baseline
monitoring and submitting the results within 10 working days from the
completion of the baseline monitoring work.
In exceptional cases
when insufficient baseline monitoring data or questionable results are
obtained, the ET shall seek approval from the IEC and the EPD on an appropriate
set of data to be used as baseline reference.
The baseline
monitoring schedule shall be issued to the IEC and EPD at least 1 week prior to
the commencement of baseline monitoring.
During periods when there are dredging works,
impact monitoring should be undertaken at the monitoring stations as shown in Figure
5.1 and Table 5.1 three times a
week. Monitoring at each station would
be undertaken at both mid-ebb and mid-flood tides on the same day. The tidal range selected for the baseline
monitoring will be at least 0.5 m for both flood and ebb tides as far as
practicable. The interval between two
sets of monitoring would not be less than 36 hours. The monitoring frequency would be increased in
the case of exceedances of Action/Limit Levels if considered necessary by
ET. Monitoring frequency would be
maintained as far as practicable.
The monitoring location/position, time, water
depth, water temperature, salinity, weather conditions, sea conditions, tidal
stage, special phenomena and work underway at the marine works site will be
recorded.
For the discharge of dechlorinated
effluent used after main sterilization, in-situ testing
of total residual chlorine should be conducted every 1 hour (not less than) at
the discharge point(s) should be conducted to ensure the level of total
residual chlorine (TRC) does not exceed < 0.2 mg/L when dechlorinated
effluent is being discharged. If the TRC
level of the dechlorinated effluent exceeds the 0.2
mg/L, discharge should be suspended and the water should be circulated to a
standby tank for further dechlorination and testing
until the TRC level complies with the required discharge standard. The Contractor is required to submit the
details of the chlorination and dechlorination
treatment facilities, treatment processes, treatment capacity, discharge
volume, methodology, chemicals use, implementation programme,
sampling location(s), discharge location(s), monitoring frequency and event and
action plan to the Engineer and verified with IEC before commencement of
sterilization work. This plan should
also be submitted to EPD for approval prior to the commencement of work.
Upon commencement of the desalination plant, an operation phase water
quality monitoring exercise would be carried out for one-year, in the same
manner as the baseline monitoring.
The effluent should be collected in a full 24-hour period. Twenty four-hour flow-weighted composite
effluent sample for subsequent chemical analysis and testing should be prepared
by the following procedures:
·
Collect effluent sub-sample at bi-hourly
interval over a 24 hour period
·
Obtain flow record of the Project for the
24-hour sampling period
·
Calculate the volume of each sub-sample for
preparation of flow-weighted composite sample
·
Transfer the appropriate volume of
sub-samples to a clean container and mix thoroughly
Continuous effluent quality monitoring shall be conducted in in
accordance with the
effluent parameters and standards stipulated by the WPCO Discharge License
conditions and therefore would not be further detailed in this document. The monitoring requirement for the continuous
effluent quality monitoring shall be approved by EPD. The effluent results reflect whether the effluent quality is in
compliance with the Discharge License
requirements. In case of non-compliance,
suitable actions shall be undertaken to notify the plant operator for the
non-compliance and identify the cause for the non-compliance. Corrective and remedial actions shall be
implemented to improve the effluent quality.
The monitoring frequency should also be increased until the effluent quality
is in compliance with the Discharge License
requirements. The non-compliance events
and preventive measures shall be documented.
For baseline, construction phase and
operation phase monitoring, each station will be sampled and measurements/
water samples will be taken at three depths, 1 m below the sea surface,
mid-depth and 1 m above the seabed. For
stations that are less than 3 m in depth, only the mid depth sample shall be
taken. For stations that are less than 6
m in depth, only the surface and seabed sample shall be taken. For in
situ measurements, duplicate readings shall be made at each water depth at
each station. Duplicate water samples
shall be collected at each water depth at each station.
The effluent sampling should be planned carefully to ensure appropriate
volume of effluent sub-samples is collected to prepare sufficient amount of
flow-weighted composite effluent sample for carrying out subsequent chemical
analysis and testing.
Water quality monitoring will be evaluated
against Action and Limit Levels. The key
assessment parameters are dissolved oxygen and suspended sediment and thus
Action and Limit Levels based on the assessment criteria are identified for
these. However turbidity can also
provide valuable instantaneous information on water quality and thus Action and
Limit Levels are also recommended for this parameter to facilitate quick
responsive action in the event of any apparent unacceptable deterioration
attributable to the works. The proposed
Action and Limit Levels are shown in Table
5.4.
Action and Limit levels are used to determine
whether operational modifications are necessary to mitigate impacts to water
quality. In the event that the levels
are exceeded, appropriate actions in Event and Action Plan (Table
5.5) should be undertaken and
a review of works will be carried out by the Contractor(s).
Any noticeable change to water quality will
be recorded in the monitoring reports and will be investigated and remedial
actions will be undertaken to reduce impacts.
Particular attention will be paid to the Contractor(s)’s implementation
of the recommended mitigation measures.

The
above actions should be taken within 1 working day after the exceedance is
identified during operation phase.
The waste management practices and
recommended mitigation measures will be incorporated into a Waste Management
Plan (WMP) as stated in the “ETWB TC(W)
No. 19/2005, Environmental Management
on Construction Sites” and C&D Material Management Plan (C&DMMP)
for the Project for managing the different types of wastes by the Contractors
on site. The Waste Management Plan (WMP) will become a part of the Environmental
Management Plan (EMP), as required under the quoted ETWB TCW No. 19/2005. The contractor is required to prepare
the EMP and submit it to the Architect/Engineer under the Contract for approval
and then implement the EMP accordingly. The
WMP will also be certified by the ET Leader and verified by the IEC as
conforming to the information and recommendations contained in the EIA
Report.
The WMP shall describe the arrangements for
avoidance, reuse, recovery and recycling, storage, collection, treatment, the
estimated rate of construction and demolition materials generation and
disposal, and the recommended mitigation measures on waste management as set
out in Section 8.5 of the EIA
Report. The WMP shall indicate the
disposal arrangements and locations of C&D materials and other wastes.
A Trip Ticket system will be included in the
WMP. Surplus excavated spoil and other
wastes will not be disposed at any other designated disposal locations unless
otherwise approved in writing by EPD, Secretary of Public Fill Committee and/or
other authorities as appropriate.
The Implementation Schedule (Annex A)
provides details on the appropriate mitigation measures for avoiding and
preventing adverse environmental impacts associated with dredged marine mud,
C&D materials, chemical wastes, general refuse and sewage from the
workforce. The WMP will be refined and
updated as more detailed information is generated on the volume of dredged
marine mud and the agreed disposal arrangements. Similarly, it will be regularly reviewed, and
updated as appropriate, throughout the course of the construction works to
confirm that it remains current with the latest detailed information and works
practices.
The WMP will also outline the requirements
for a waste audit program to verify that the measures outlined in the plan are
effectively implemented and adhered too.
The construction
Contractor(s) must confirm that the necessary disposal permits or licences are
obtained from appropriate authorities in accordance with the various
Ordinances. In addition to the monthly
joint inspections/ audits, each construction Contractor(s) will designate a
member of staff as being responsible for routine inspections and audits of
on-site waste management practices, with reference to the relevant legislation
and guidelines as well as the recommendations given in the Implementation

To review
the WMP including the quantities and types of C&D materials generated,
reused and disposed of off-site; the amount of fill materials exported
from/imported to the site and the quantity of timber used in temporary works
construction for each process/activity;
·
To confirm
that the wastes arising from works are handled, stored, collected, transferred
and disposed of an environmentally acceptable manner and comply with the relevant
requirements under the Waste Disposal
Ordinance (WDO) and its regulations;
·
To confirm
that the construction Contractor(s) properly implements the appropriate
environmental protection and waste pollution control mitigation measures, as
outlined in the WMP and the Implementation Schedule and presented in Annex
A, to reduce and control the potential for waste impacts;
·
To monitor
the implementation and achievement of the WMP on site to assess its
effectiveness; and
·
To monitor
the follow-up action on deficiencies identified.
Weekly audits of the waste management practices
will be carried out during the construction phase to determine if wastes are
being managed in accordance with the recommended good site practices, WMP and
C&DMMP. Joint site inspections and
audits by the ET, the IEC and the contractor will be undertaken once per
month. The inspection/ audit will look
at all aspects of on-site waste management practices including waste
generation, storage, recycling, transport and disposal. Particular attention will be given to the
contractor’s provision of sufficient spaces, adequacy of resources and
facilities for on-site sorting and temporary storage of C&D materials. The C&D materials to be disposed of from
the site will be visually inspected. The
public fill for delivery to the off-site stockpiling area will contain no
observable non-inert materials (e.g. general refuse, timber, etc). Furthermore,
the waste to be disposed of at refuse transfer stations or landfills will as
practicable contains no observable inert or reusable/recyclable C&D
materials (e.g. soil, broken rock, metal, and paper/cardboard packaging, etc). Apart from
site inspection, documents including licences,
permits, disposal and recycling records will be reviewed and audited for
compliance with the legislation and Contract requirements. Any irregularities observed during the site
audits will be raised promptly to the contractor for rectification.
The findings
of the waste audits will be reported in the Monthly EM&A Reports, Quarterly
EM&A Reports and Annual/Final EM&A Reports.
The land
contamination assessment has examined the potential contaminating land uses
within the Project area and investigated the potential impacts of the
contamination on future use. A site
reconnaissance was conducted on 7 August 2014 and potential land contaminating
risks were identified at the generator room and the waste chemical drum storage
at the side of the vehicle access road.
Based on assessment result, only the area covered by the TMS Site was
identified with low risk of potential land contamination.
Before the
hand-over of the TMS Site to WSD for further development, the owner of TMS Site
and its contractor shall ensure the TMS site is properly cleaned up before
handover to CEDD. After the TMS Site is
handed over to WSD and before the commencement of any construction work, the
contractor of WSD shall prepare a Contamination Assessment Plan (CAP) for EPD
endorsement prior to the commencement of site investigation. A Contamination
Assessment Report (CAR) shall be prepared to summarise
the results of the site investigation.
If land contamination is identified, a Remediation Action Plan (RAP)
shall be prepared to identify feasible remediation methods and a Remediation
Report (RR) shall be prepared to demonstrate completion of remedial actions for
EPD endorsement. In addition, mitigation
measures to minimize the potential adverse effect to the environment due to the
handling of contaminated materials shall be properly implemented (Annex A).
Visual
inspection at all facilities during construction stage of the Project is
recommended as best practice during construction activities associated with
disturbed soil (Annex A).

Design Phase
-
Cut-off barrier to seal any service trench
entering the buildings within the Project Site and LFG consultation zones. Figure
B.6 in the Guidance Note provides details of a suitable design; and
-
Grilled metal covers are required to be used for the
below grade cable trenches entering the buildings within the Project Site and LFG
consultation zones.
·
Construction Phase
-
All workers should be aware of potential
presence of LFG;
-
Train and provide breathing apparatus and gas
detection equipment for confined spaces or deep trenching;
-
Impact monitoring should be conducted before
excavations of 1m depth or more and/ or drilling operations within the Project
Site and LFG consultation zones;
-
Safety precautions should be made available
during trenching, excavation and creation of confined spaces near to or below
ground level; and
-
Provision of Safety officers, specifically trained with regard to
landfill gas and leachate related hazards and the appropriate actions to take
in adverse circumstances, on the site throughout the works.
·
Operational Phase
-
Alert workers and visitors of possible LFG
hazards;
-
Prohibit smoking and open fires on site; and
-
Conduct regular LFG monitoring at buildings,
manholes, utility pits within the Project Site and consultation zones, etc.
· at the
ground surface before excavation commences;
· immediately
before any worker enters the excavation;
· at the
beginning of each working day for the entire period the excavation remains
open; and
· periodically through the
working day whilst workers are in the excavation.
For excavations between 300mm and 1m deep,
measurements should be carried out:
· directly
after the excavation has been completed; and
· periodically whilst the
excavation remains open.
In
the case that drilling operations are required to be carried out within any of the
landfill consultation zones, the following additional recommendations
should also be adopted, including:
· Proceed
drilling with adequate care and precautions against the potential hazards which
may be encountered;
· Prior to the
commencement of the site works, the drilling contractor should devise a
'method-of-working' statement covering all normal and emergency procedures
(including but not limited to number of operatives, experience and special
skills of operatives, normal method of operations, emergency procedures,
supervisors responsibilities, storage and use of safety equipment, safety
procedures and signs, barriers and guarding).
The site supervisor and all operatives must be familiar with this
statement.
For the
manholes and utility pits within the Project Site and along the fresh water
mains, each manhole/ utility pit should be monitored with two measurements (at
mid depth and base). Each measurement
should be monitored for a minimum of 10 minutes. A steady reading and peak reading should be
recorded at each manhole/ utility pit and for each measurement. The need for venting the manhole/ utility pit
and further monitoring will be reviewed after the initial monitoring. As the exact location of these will be
dependent upon the detailed design of the desalination plant and fresh water
mains, these locations cannot be specified prior to completion of the detailed
design.
The Limit levels and
EAP for LFG detected in excavations, utilities and any enclosed on-site areas
are shown in Table 11.1 below.

There will be contractual
environmental protection and pollution control requirements as well as
The ET Leader should review the
progress and programme of the works to check that relevant
environmental laws have not been violated, and that any foreseeable potential
for violating the laws can be prevented.
The Contractor should also
regularly copy relevant documents to the ET Leader, IEC, ER and Project
Proponent so that the checking work can be carried out. The relevant documents are expected to
include the updated Work Progress Reports, the updated Works Programme, application letters for
different licences/permits under the environmental
protection laws, and all the valid licences/permit. The site diary should also be available, upon
request, to the ET Leader during his site inspection.
After reviewing the
documentation, the ET should advise IEC, ER, Project Proponent, EPD and
Contractor of any non-compliance with the contractual and legislative
requirements on environmental protection and pollution control for them to take
follow-up actions. If the ET Leader's
review concludes that the current status on licence/permit
application and any environmental protection and pollution control preparation
works is incompatible with the works programme or may
result in potential violation of environmental protection and pollution control
requirements by the works in due course, he should also advise the Contractor
accordingly.
Upon receipt of the advice, the
Contractor should undertake immediate action to remedy the situation. The ET, IEC and ER should follow up to ensure
the appropriate actions have been taken by the Contractor in order that the
environmental protection and pollution control requirements are fulfilled.
The ET Leader should
undertake the following procedures upon receipt of a complaint:
During the complaint
investigation work, the Contractor and ER shall cooperate with the ET Leader in
providing all necessary information and assistance for completion of the
investigation. If mitigation measures
are identified in the investigation, the Contractor should promptly carry out
the mitigation measures. EPD will
approve the proposed mitigation measures and the ET Leader and IEC should check
that the measures have been carried out by the Contractor.
The ET Leader should keep a
contemporaneous log-book of each and every instance or circumstance or change
of circumstances which may affect the findings of the environmental impact
assessment and non-compliance with the Environmental Permit. The ET Leader should notify the IEC within
one working day of the occurrence of any such instance or circumstance or
change of circumstance. The ET Leader’s
log-book should be kept readily available for inspection by persons (such as
IEC and Contractor) assisting in supervision of the implementation of the
recommendations of the EIA Report and the conditions set out in the Environmental
Permit, or by EPD or his authorised officers.
The ET Leader shall prepare and submit a Baseline Environmental
Monitoring Report within 10 days of completion of the baseline monitoring. The Baseline Monitoring Report will be submitted
to the Contractor, IEC, ER and EPD. The
baseline monitoring report will include at least the following:
(a) up to half a page executive summary;
