INTRODUCTION This Environmental Management Plan (EMP) is to
describe the environmental issues in this project of Drainage
Service Department (DSD) with the contract no. DC/2007/12, which is
a Designated Project (DP) defined under the Environmental Impact
Assessment (EIA) Ordinance. In this plan, the arrangements for the
environmental nuisances; and avoidance, reuse, recovery and
recycling, storage, collection, treatment and disposal of different
categories of waste to be generated from the construction
activities throughout the construction period are demonstrated. It
is required to comply with all the requirements as specified in the
EIA Report and the conditions specified in the Environmental Permit
(EP) including any variation of the Environmental Permit; and a
Variation Environmental Permit (VEP) if the conditions during
construction are different from that specified in the Approved EIA
Report. The Project has also to implement the EM&A programme in
accordance with the procedures and requirements included in the
Environmental Monitoring and Audit (EM&A) Manual to ensure the
implementation and the effectiveness of the environmental
protection and pollution control measures to be adopted properly.
The approaches of environmental management system is illustrated in
the EMP, which will be implemented that to assure the requirements
stated in the EIA report are effectively fulfilled during the
project. It also demonstrated the management framework and target
that to achieve the continuous improvements, e.g. reduce
environmental nuisances and Construction and Demolition (C&D)
materials arising from Works. The mitigation measures in different
categories of environmental issues are also set out that will be
executed during construction during construction period, to attain
the requirements stated in the EIA report. Awareness of the
environmental responsibilities of Maeda-CREC-SELI Joint Venture
(the JV) environmental management team in the EMP can be
demonstrated that the implementation of EMP comprises not only the
statuary legislation, but also the requirements of contract and the
EIA Report. It will ensure the effective contract specific
implementation and reporting on compliance with the stated
mitigation measures, as well as the monitoring and auditing
requirements and remedial actions defined in the EIA Report In
addition, the implementation of EMP provides evident and records to
the JV to meet the requirements and be granted merit of the
standard of management system, e.g. ISO 9000/18000, from the
profession institutes. This document is cross referenced to the
procedures of Maeda Corporations (Joint Venture Leaders) Quality
and Environmental Manual where appropriate. The contents of the
project EMP will include the following details: A) The commitment
and strategy in implementation of the environmental management on
the site. B) Organization structure and duties and responsibility
of staffs in the environmental management system. C) Details of

Environmental Monitoring and Audit (EM&A) Manual The
Environmental Permit imposes the requirements for monitoring the
environmental impacts of the project for verification of
predictions or the effectiveness of measures to mitigate its
environmental impacts whether such impacts occur within or outside
the physical boundary of the project. The Environmental Permit also
imposes the requirements for the formulation of environmental
audit, including any necessary compliance, in order to review the
environmental monitoring data, assess compliance with regulatory
requirements, policies and standards, and identify any remedial
works required to redress unacceptable or unanticipated
environmental impacts. Before the commencement of construction,
Maeda-CREC-SELI Joint Venture shall undertake baseline monitoring
in accordance with the updated EM&A Manual. The Environmental
Monitoring and Audit (EM&A) Manual is: to guide the set up of
an EM&A programme to ensure compliance with the Environmental
Impact Assessment (EIA) study recommendations, to assess the
effectiveness of and to identify any further need for additional
mitigation measures or remedial action.
The EM&A Manual outlines the monitoring & auditing
protocols which will be necessary to achieve the objective of the
EM&A programme. For details please refer to Section 14 of this
EMP. Implementation of the EM&A programme by the Environmental

PERFORMANCE MONITORING Environmental Inspections For the purpose
of monitoring environmental performance, the Joint Ventures EMS
includes a monitoring mechanism in addition to the EM&A
programme outlined in the contract specific EM&A Manual which
is specified below. Monitoring of environmental performance shall
be conducted at two principal levels. Firstly, the construction
personnel shall on an ongoing basis, through their normal
surveillance of site operations, ensure the compliance of site
activities, including the operations of subcontractors, with:
Legislative requirements pertaining to the works; Specific
stipulations required by EPD (e.g. conditions of permit or
licences); Approved method statements; and General site
practices
Secondly, the Project Environmental Officer / Supervisor shall
undertake monthly audit checks on all site activities in order to
ensure fulfillment of environmental requirements in the Contract
including licenses or permits. Such checks shall be site-wide and
encompass all pertinent environmental issues applicable to the
ongoing works. In addition, regular environmental management system
audits will be conducted by the Maedas Quality and Environmental
Manager to review the overall environmental performance in
accordance to the Project specific requirements, e. g. EMP, and the
JV EMS that follow ISO 14000:2004 Standard. As according to the
contract requirement, joint weekly environmental inspections will
be required. The inspection team comprises Joint Venture
environmental officer, the Contractors Agent and representative of
the Supervising Officer or Employer. According to the EM&A
Manual, bi-weekly environmental site inspection will be carried out
by ET. Project Specific and comprehensive checklists, namely the
Environmental Monitoring Record (EMR) as attached at Appendix 13
for site inspections, will be developed with the agreement of
Supervising Officer. 8.2 Environmental Non-conformance (NC)
Exceedance cases of monitoring results, complaints, site
deficiencies, violations of legislation or contractual clauses, if
confirmed to be work-related, can be considered as nonconformances.
All suspected incidents of non-conformance whether originated
internally or by others (including the SO, ET, IEC, EPD and the
like) shall be brought to the attention of the Project
Environmental Officer for his/her further action.Page 24 of 67

The Project Environmental Officer shall establish the facts
concerning the suspected incident. Having established a basic fact
of a non-conformance, the Project Environmental Officer shall raise
a non-conformance report (environmental) (NCR(E)) to the concerned
parties for followup action. A copy of the proforma is attached at
Appendix 13. Following the above the Project Environmental Officer
/ Supervisor shall obtain acknowledgement of the NC from the
parties responsible by having them sign the NCR(E). The party
responsible for the NC occurrence shall determine the underlying
reason(s), methods of redressing the occurrence and means of
ensuring similar NC does not happen again. The Project
Environmental Officer / Supervisor shall review the proposed
corrective / preventive actions for adequacy. The proposed
corrective actions and preventive action will be agreed with
Supervising Officer. Upon receipt of a duly approved NCR(E) the
party responsible shall undertake the proposals as approved.
Proposed corrective / preventive actions shall be monitored during
their execution, expedited as necessary, and verified for adequacy
upon completion. The closing of the identified non-compliance will
be subject to the agreement of the Supervising Officer. 8.3 Top
Management Site Safety and Environmental Inspection To show the
commitment of JVs top management to environmental control and
improvement, the top management of the Hong Kong Office will
inspect in person the active construction sites on a half-year
basis. The inspection will focus on areas of housekeeping, surface
runoff / site effluent management, dust control, waste management
and mosquito breeding control. Comments or advice arising from the
inspection will be recorded and conveyed to the project senior
management for follow-up actions. 8.4 Daily Safety &
Environmental Coordination Meeting Chaired by the Construction
Managers or their designated representatives, the site internal
meeting will be held daily at 13:00 to provide an opportunity for
the Joint Venture together and sub-contractors to exchange site
information and report any important issues. Assigned supervisory
staff including sub-contractors will attend the meeting.

REVIEW OF REQUIREMENTS Environmental performance review
comprises the regular assessment of the effectiveness of the EMP,
site practices and procedures to ensure the required mitigation
measures are routinely implemented and that they are being
effective in achieving the required environmental standards. The
criteria of the reviews shall be derived from the following: the
approaches, procedures and commitments given under the EMP of JV;
the clauses contained within the JVs internal and or Contractual
Documentation; and those parts of the JV method statements which
relate to the minimisation of environmental impacts or other
specified environmental protection measures.
The reviews shall focus on the effectiveness of the implemented
measures to achieve the purpose, not simply the fact that a measure
has been implemented. Review protocols shall be developed by the
JVs Project Environmental Officer with the assistance of ET Leader
prior to the commencement of works and it is suggested that the
protocols should include inspection and auditing of the following:
the allocation of responsibility for fulfilling environmental
requirements, and agreed mitigation measures, and the effectiveness
of lines of communication with regard to environmental issues;
compliance with procedures established to enable an effective
response to environmental incidents, exceedances or non-compliance;
the extent and accuracy of record-keeping related to environmental
performance indicators; the effectiveness of staff training in
ensuring high levels of awareness with regard to environmental
requirements; and the effectiveness of environmental management
activities.
The protocols shall comprise checklists of environmental
requirements and shall be amended, throughout the construction
phase as necessary, to focus on areas of frequent non-compliance
and to reflect the potential impacts associated with specific
activities within the construction programme. The JVs Project
Environmental Officer shall review, at the commencement of the
construction project, details of the locations of sensitive
receivers used for air, noise and water that have been identified
in the EIA and any other potential sources of environmental
nuisance arising from the construction works.

ENVIRONMENTAL EMERGENCY PROCEDURE Emergency procedures for
dealing with exceptional circumstance, outside normal operational
parameters, resulting in heightened environmental impacts such as:
Fire with extinguishing fluids and fire-damaged materials arising;
Spillage of fuels and chemicals, or loss of containment thereof;
Discharge of significant amounts of wastewater and construction
run-off to any Public drainage system or out of the Site
particularly during adverse weather. Receiving any complaint on the
environmental aspects from external parties including the Employer,
Government Departments and the Public.
Fire Initially, the Project Safety Plan shall be followed in
order to summons the emergency services and provide for the orderly
evacuation of personnel from affected areas. Throughout the fire
fighting operations the principal concerns must necessarily be the
preservation of life and the extinguishing of the fire. Spillage
Spillage may occur for a number of reasons despite various
precautions. Where spillage of liquid occurs on an impermeable
surface, it shall be covered with sand or proprietary soak-up
materials where available until such time as it has been absorbed
and may then be removed. If spillage on permeable surface, then
contaminated material will be removed where necessary to do so, and
reinstated with clean material. Thereafter, the spillage or
contaminated materials shall be suitably contained for disposal as
chemical waste. To ensure all workers are aware of the proper
procedures to handle spillage, drills will be conducted regularly.
In addition, a spill control and response plan has been prepared
for works at the Intakes and work sites specified in the EIA
Report. Rainstorm In addition to the foregoing precautions the
following are to be taken at any time of year when rainstorms are
likely: Temporarily exposed surfaces will be covered e.g. by
tarpaulin. Temporary access roads will be protected by crushed
stone or gravel. Trenches will be dug and backfilled in short
sections. Measures will be taken to minimize the ingress of
rainwater into trenches.Page 29 of 67

Discipline In-service Training Workshop EN-C023 Construction
Environmental Management Plan
Actions to be taken when a rainstorm is imminent or forecast:
Silt removal facilities, will be checked to ensure that they can
function properly. Open stockpiles of construction materials on
site will be covered with tarpaulin or similar fabric. All
temporary covers to slopes and stockpiles will be secured. Actions
to be taken during or after rainstorms: Silt removal facilities
will be checked and maintained to ensure satisfactory working
conditions.
Flooding To avoid the potential discharge of significant amounts
of wastewater to any public drainage system and out of the Site
area, regular inspections are required on the stomewater drains,
surface channels or temporary drainage systems within and adjacent
to the works site, particularly if there is adverse weather
forecast, In the event of flooding, we will immediately bund off
the source of discharge or the outlets with sufficient sandbags;
and try to block the source and stop the related operations. If the
situation continues, then we will divert or pump the discharge to
the waste water treatment facilities. External Complaints To
facilitate the immediate response to external complaints relating
to environmental issues, the Environmental Officer and/or the
Project Manager, whoever is available, should be contacted for
handling and resolving the event. A non-conformance report will be
raised to monitor the closing and settlement of the issues
following the procedure as specified at section 8.2 above.
Reporting In any of the above cases including any complaints
received on the environmental aspects from external parties, all
site personnel shall be aware that the Project Manager and the
Environmental Officer are to be notified of such occurrence of
environmental incidents. The Project Manager shall then notify the
Supervising Officer as soon as practicable and furnish a detail
report, if required.

site are required to run on Ultra-Low-Sulphur Diesel (ULSD) fuel
that contains not more than 0.005% by weight of sulphur. All
deliveries and consumption of ULSD diesel on site shall be recorded
by the Environmental Officer/ Supervisor with details of date of
delivery, name of supplier, quantity and plants used etc. on the
Summary for Delivery of ULSD form, which is included in Attachment
13. The summary is required to be submitted to the Supervisor
Officer monthly for review. 12.2 Noise Tunneling works are expected
to be undertaken over the 24 hours period each day. The depth of
the tunnel ranges from 7m to 200m below ground level. With regard
to 24-hour working, a Construction Noise Permit (CNP) will be
necessary for the construction during restricted period as the main
tunnel will be driven by TBM (Working 24 hours). During restricted
hours, construction activities will be contained within the tunnel.
All material excavated during restricted hours will be stockpiled
and will be removed off site only during normal working hours (7am
to 7pm). These measures will significantly reduce noise generated
from tunnel construction during night time.

Construction Noise Permits for any works in restricted To be
processed upon contract hours award Noise impacts that arise from
general construction works during normal working hours (i.e. 0700
to 1900 hours on any day not being a Sunday or public holiday) at
the openable windows of noise sensitive buildings are to be
assessed as per the guidelines contained in the TMEIA. The
recommended noise standards are 75dB(A) for domestic premises,
70dB(A) for educational institutions, 65dB(A) during examinations,
which shall be measured immediately 1 metre outside the external
wall/ window of the closest sensitive noise receiver, like
residential building and school. If construction works cannot be
carried out in normal working hours construction with the use of
Powered Mechanical Equipment (PME) Construction Noise Permit (CNP)
shall be obtained from the EPD. The EPD is guided by the GW-TM when
assessing such an application. EPD will compare the Acceptable
Noise Levels ANLs, as promulgated in the GW-TM, and the Corrected
Noise Level (CNLs) (after accounting for factors such as barrier
effects and reflections) associated with the proposed PME
operations. A CNP will be issued if the CNL is equal to or less
than the ANL. The ANLs are related to the noise sensitivity of the
area in question and different Area Sensitivity Ratings (ASR) have
been drawn up to reflect the background characteristics of
different areas.

Determination of the Area Sensitivity Ratings for the NSRs in
the EIA report has been made with reference to relevant TMs. For
the NSRs at Intake 1 and outfall 1, an Area Sensitivity Rating of C
is assigned as the area is classified as the urban area and
directly influenced by road traffic noise from major roads (i.e.
Cheung Pei Shan Road and Tuen Mun Road). For the NSRs at Intakes 2
and 3, an Area Sensitivity Rating of A is assigned as the area is
classified as low density area and not influenced by road traffic
noise from main roads. Ground-borne Noise and Vibration TBM and
breaking activities will be used to excavate rock. The interaction
between the operation of equipment and the rock will induce ground
borne noise and vibration, the varying extent depending on the
geological conditions and equipment used. TM for the Assessment of
Noise from Places other than Domestic Premises, Public Places or
Construction Sites (PL-TM) under the NCO stipulates that noise
transmitted primarily through the structural elements of building,
or buildings, shall be 10 dB(A) less than the relevant ANLs. Based
on the principle for ground borne noise criteria (i.e. taking
account of the minus 10dB (A) requirement under the NCO PL-TM),
ground borne construction noise levels inside domestic premises and
schools relying on open window for ventilation will be limited to
65dB(A) and 60dB(A) respectively, with reference to the daytime
airborne noise criterion of 75dB(A) and 70dB(A) in accordance with
TMEIA. In the evening (1900 2300hrs) and during night time (2300
0700hrs), ground borne noise level will be limited to 10dB(A) below
the respective ANLs for the Area Sensitivity Rating category of A,
B and C at the NSRs along the proposed project. A summary of these
criteria is

All works shall be stopped immediately if the maximum noise
level exceeds the limit and necessary mitigation measures shall be
taken to reduce the noise levels to within the acceptable range. In
the assessment, practicable direct noise mitigation measures have
been identified and recommended to achieve the noise criteria as
far as practicable. Provision of indirect technical remedies in the
form of noise insulation, shield, barriers or enclosure is
considered. List of activities on the Sites that will cause noise
pollution 1) Tunneling and its backup system, e.g. conveyor belt
system, hopper 2) Site formation at Outfall O-1 & Intake I-3
including bulk excavation, soil nailing and removal of boulders; 3)
Piling work at Outfall O-1, Intake I-1, I-2 & I-3 including
temporary & permanent soldier piles & temporary pipe piles;
4) Pipes jacking at Intake I-2; 5) Excavation at the Outfall and
Intake sites including temporary / permeation grouting; 6)
Operation of ancillary equipment, e.g. air compressor, generator,
bulk material Loading/unloading and feeding system. Particular site
abetment measures corresponding to the above activities: For 1)
tunneling and its back-up system, A noise enclosure constructed
with noise absorbent acoustic materials as the internal lining will
be provided to enclose the portal, gantry crane system and the
spoil hoppers. The set-up will be adequate to reduce noise level to
enable tunneling work at night. For activities 2) to 6), (i) (ii)
(iii) Movable noise barriers will be provided to enclose / screen
the noise generating activities as far as practicable; Noise labels
will be displayed on each noise concern areas where the noise level
at these areas may be exceeding required level from time to time
during operation; All staff are required to wear a proper ear
protectors at the noise concerned workingPage 42 of 67

area as needed, e.g. during breaking of rock; Noise measuring
devices will be provided at the sensitive locations to monitor the
noise levels; Alert, alarm and action system is adopted;
General Noise Minimisation and Mitigation Measures
The construction of Works may lead to noise generation if noise
mitigation measures are not undertaken. It is predicted that
various construction activities associated with the earthworks,
excavation and construction may cause temporary impacts without
mitigation. Best practice measures, Quiet plant and mobile noise
barriers are recommended to suppress noise emissions from
construction activities where noise exceedance is anticipated.
Appropriate mitigation measures such as the use of quiet equipment
and movable barriers will be developed to ensure that noise can be
reduced to acceptable levels without causing programme delays. 1.
Good site practice and noise management can significantly reduce
the impact of construction site activities on nearby NSRs. The
following package of measures will be followed during
construction:
Only well-maintained plant will be operated on-site and plant
will be serviced regularly during the construction period; Machines
and plant that may be in intermittent use will be shut down between
work periods or will be throttled down to a minimum; Plant known to
emit noise strongly in one direction, should, where possible, be
orientated to direct noise away from the NSRs; mobile plant should
be sited as far away from NSRs as possible; and Material stockpiles
and other temporary structures should be effectively utilised,
where practicable, to screen noise from on-site construction
activities. All hoods cover panels and inspection hatches of
powered mechanical plant such as generator, air compressors etc.
shall be closed during operation. Application of properly designed
silencers, mufflers, acoustically dampened panels and acoustic
mats/ sheds consider being adapted to operating noisy plants.
Summary of noise emission labels for QPME used on site will be
maintained updated by the Environmental Engineer or Supervisor.
Temporary/ movable full height noise barriers, will be constructed
to block the line of sight to the sensitive receivers if found
necessary. The barriers will be constructed using acoustic
materials or materials to achieve the best noise reduction
performance. Please refer to Attachment 7 for the sketch of Typical
Noise Barrier.

3. Tunnel Excavation Work
For the tunnel excavation, it is anticipated that excavation
will be carried out well within the main tunnel within the initial
length (approx. 25m for the Launching Chamber), and at the openings
leading to the connection adits tunnels, however, appropriate noise
enclosures will be also provided to further minimize the noise
nuisance to the nearby receivers if necessary. To alleviate the
construction noise impact at the tunnel Portal located at Outfall
O-1 where 24-hour working is to be undertaken, noise enclosures
shall be constructed with appropriate dimensions, approximately
10mH x15mW x 45mL will be extended to cover the openings of the
tunnel structure and temporary ancillary structures. To enhance the
noise reduction effect, absorbent acoustic panels with noise
absorbent acoustic materials as the internal lining or for noise
enclosure will be used. It is envisaged that the noise impact can
be reduced by max. 35dB. Major plant and equipment like the TBM,
Overhead Crane, Belt Conveyor, Diesel Loco, Gravel Loader (Small
belt conveyor) including the tunnel ventilation system and the muck
pit area will be housed inside the noise enclosure. Please refer to
Attachment 8 for the layout and sketch of the acoustic noise
enclosure at the Tunnel portal. Prior to the erection of noise
enclosure for the TBM, temporary noise barriers shall be erected to
mitigate noise impact for construction of access road from Castle
Peak Road leading to the Outfall O-1, site formation, tunnel portal
formation, and various ancillary works.
Preventive Action 1. Regular site inspections and surveillance
will be conducted throughout the construction period to monitor the
construction noise conditions especially at the work areas where
noisy equipment is in operation. The inspection details are
mentioned in Section 8.1 above. 2. A Permit to Work System will be
implemented strictly in accordance with the JVs standard procedure
for all works within restricted hours , i.e. from 1900-07:00 hours
and all time on Sundays and general holidays for general works
other than percussive piling. We will ensure that works are
executed with proper supervision under a valid CNP and in
compliance with the conditions specified under the CNP. 3. Ad hoc/
un-announced inspections will be arranged by the Environmental
Officer/ Supervisor to verify and ensure the compliance of permits
condition in respect of plant and work schedules during restricted
works hours. Non-conformance reports will be raised for any
deficiencies. Please refer to Section 8.2 above. 4. Before the
commencement of any work that may generate a significant noise
impact, method statements shall be submitted to the Supervising
Officer for approval providing details such as methods of working,
equipment and sound-reducing measures (e.g. uses of silenced type
of equipment, etc.) intended to be used.Page 44 of 67
