Introduction
1.1
Purpose of the
Manual
Changjiang
Water Resources Protection Institute (CWRPI 長江水資源保護科學研究所) in association with ERM-Hong Kong Ltd was jointly commissioned by the
Shenzhen River Regulation Office of the Shenzhen Municipal Government (深圳市治理深圳河辦公室) and the Drainage Services Department (DSD) of the HKSAR Government to undertake
an Environmental Impact Assessment (EIA) Study for the Regulation of Shenzhen
River Stage 4 (hereafter referred to as the Project). This Environmental Monitoring and Audit (EM&A)
Manual (hereafter referred to as the Manual) is a supplementary document to the EIA
Report.
The Manual has been prepared in accordance with the EIA Study Brief (No. ESB
- 200/2008) 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 of the Project. It provides systematic procedures for monitoring
and auditing the environmental performance of the Project.

embankment construction, sewage diversion works and landscaping works.
1.3
Objective of the
EM&A
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 described
in the EIA Report. The EIA Report also
specifies mitigation measures and good construction practices that will be needed to comply with the
environmental criteria or further minimise the potential impacts. These mitigation measures and their implementation
requirements are presented in the Implementation Schedule of Mitigation
Measures (see 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 measures recommended in the EIA Report are properly
incorporated into the design of the Project;
·
confirm
that the design complies with the recommendations of EIA Report and the
conditions of Environmental Permit (EP);
·
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;
·
monitor
performance of the mitigation measures and to assess their effectiveness;
·
take
remedial actions if unexpected issues or unacceptable impacts arise;
·
verify
the environmental impacts predicted in the EIA; and
·
audit
environmental performance.
The EIA Study indicates that an EM&A programme
will only be required for the construction and post-construction phases of this
Project. Unacceptable environmental
impacts are not predicted to occur during the operation phase, an EM&A
programme for the operation phase is not considered necessary. A summary of the requirements for each of the
environmental parameters is detailed in Table 1.2.

Arrangement for
Advanced Works and River Modification Works Contract
The Project construction will be undertaken
by two separate contracts, one for the Advanced Works within the HKSAR and one
for the River Modification Works within both the HKSAR and the Shenzhen Municipality. The EM&A organisation and structure for
both contracts shall be the same. Environmental
site audit is recommended for both contracts to ensure that the good
construction site practices are implemented.
As the scale and nature of the Advanced
Works is small and the EIA Report concluded that the construction of the
Advanced Works will not cause adverse environmental impact, environmental
monitoring is not required for the Advanced Works. The environmental monitoring requirement for
the River Modification Works is specified in Sections 3 and 4 of this
Manual.

EM&A
General Requirements
2.1
Introduction
In this section, the general requirements of the
EM&A programme for the Project are presented. The scope of the programme is developed with
reference to the findings and recommendations of the EIA Report.
2.2
Construction
Phase EM&A
2.2.1
General
Potential environmental impacts, 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 Manual and in the construction contracts.
During the construction phases of the Project, air
quality, noise, water quality, ecology, landscape and visual and waste will be
subject to EM&A, with environmental monitoring being undertaken for
construction dust and noise 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.
2.2.2
Environmental Monitoring
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 cover construction dust and noise and will form an important part of the
whole EM&A programme.
2.2.3
Action and Limit (A/L) Levels
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: levels beyond
which there is a clear indication of a deteriorating environmental conditions
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,
Hong Kong Planning Standards and Guidelines (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.
2.2.4
Event and Action Plans (EAPs)
The purpose of the EAPs is
to provide, in association with the monitoring and audit activities, procedures
for ensuring that if any significant environmental incident occurs, the cause
will be quickly identified and remediated.
This also applies to the exceedances of A/L
limits identified in the EM&A programme.
2.2.5
Site Inspections & Audits
In addition to construction dust and noise monitoring
as a means of assessing the ongoing performance of the Contractor(s), the ET
will undertake site inspections of on-site practices and procedures each
month. The primary objective of the
inspection 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 monthly site audits to
assess the performance of the Contractor(s) and the effectiveness of the ET.
Whilst the inspection and audit programme will
complement the monitoring activity, the criteria against which the inspection/
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
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 10 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.
2.2.6
Enquiries, Complaint and Requests for
Information
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.
Enquiries, complaints and requests for information
concerning the environmental effects of the construction works, irrespective of
how they are received, will be reported to DSD and directed to the ET which
will set up procedures for the handling, investigation and storage of such
information. The following steps will
then be followed:
1)
The
ET Leader will notify DSD of the nature of the enquiry.
2)
An
investigation will be initiated to determine the validity of the complaint and
to identify the source(s) of the issue.
3)
The
Contractor(s) will undertake the following steps, as necessary:
·
investigate
and identify source(s) of the issue;
·
if
considered necessary by DSD following consultation with the IEC, undertake
additional monitoring to verify the existence and severity of the alleged
complaint;
·
liaise
with EPD to identify remedial measures;
·
liaise
with the IEC to identify remedial measures;
·
implement
the agreed mitigation measures;
·
repeat
the monitoring to verify effectiveness of mitigation measures; and
·
repeat
review procedures to identify further practical areas of improvement if the
repeat monitoring results continue to substantiate the complaint.
4)
The
outcome of the investigation and the action taken will be documented on a
complaint log (see Annex D). A formal response to each complaint received
will be prepared by the Contractor(s) within five working days and submitted to
DSD, in order to notify the concerned person(s) that action(s) has been taken.
5)
Enquires
which trigger this process will be reported in the monthly EM&A Reports
which will include results of inspections undertaken by the Contractor(s), and
details of the measures taken, and additional monitoring results (if deemed
necessary). It should be noted that the
receipt of complaint or enquiry will not be, in itself, a sufficient reason to
introduce additional mitigation measures.
The complainant will be notified of the findings, and
audit procedures will be put in place to verify that the issue does not recur.
2.2.7
Reporting
Baseline and impact monitoring, monthly, quarterly
and final reports will be prepared by the ET on behalf of DSD and certified by
the ET Leader and verified by the IEC.
The reports will be submitted to the Contractor(s), DSD and EPD. The monthly EM&A Reports will be prepared
and submitted within two weeks of the end of each calendar month.
2.2.8
Cessation of EM&A
The cessation of EM&A programme is subject to the
satisfactory completion of the Final EM&A Report, agreement with the IEC
and approval from EPD.
2.3
Operation Phase
EM&A
As no unacceptable impacts were identified during the
operation phase of the Project, no EM&A programme is considered necessary
for the operation phase. However, should
other operational licenses that require specific monitoring or audit conditions
or practices be required, plans under the respective ordinances/ guidelines
will need to be put in place.
3
Air Quality
3.1
Introduction
Environmental site audit is required for ensuring implementation
of recommended dust control measures and monitoring of dust is required during
the construction phase of the River Modification Works. Since no adverse air quality and odour
impacts are anticipated during the operation phase, no EM&A programme is
required.
The general requirements, methodology, equipment, and
mitigation measures for the monitoring and audit of potential construction
phase air quality impact are described in the following sections. The mitigation measures recommended to control air quality impacts are summarised
in Annex A.
3.2
Monitoring
Parameters
Monitoring of the Total Suspended Particulates (TSP)
levels will be carried out by the ET to ensure that construction works will not
cause adverse dust impacts to identified air sensitive receivers (ASRs). Timely action shall be taken to rectify the
situation if an exceedance is detected. All relevant data including temperature,
pressure, weather conditions, elapsed-time meter reading for the start and stop
of the sampler, identification and weight of the filter paper, any other
special phenomena and work progress of the concerned site shall be
recorded. A sample data log sheet is
shown in Annex B.
3.3
Monitoring
Location
Two locations are proposed for construction dust
monitoring as listed in Table 3.1. The locations of the monitoring station are
presented in Figure 3.1.

the following points shall be noted:
·
a
horizontal platform with appropriate support to secure the samples against
gusty wind shall be provided;
·
no
two samplers shall be placed less than 2m apart;
·
the
distance between the HVS and an obstacle,
such as buildings, must be at least
twice the height that the obstacle protrudes above the HVS;
·
a
minimum of 2m separation from walls,
parapets and penthouses is required for HVS at the rooftop;
·
a
minimum of 2m separation from any supporting structure,
measures horizontally is required;
·
no
furnace or incinerator flue is nearby;
·
airflow
around the sampler is unrestricted;
·
the
HVS is more than 20m from the dripline;
·
any
wire fence and gate to protect the HVS, shall not cause any obstruction during
monitoring;

permission
must be obtained to set up the HVS and to obtain access to the monitoring
stations; and
·
a secured
supply of electricity is needed to operate the HVS.
3.4
Monitoring
Equipment
Continuous 24-hour and 1-hour monitoring shall be
performed using HVS with appropriate sampling inlets installed, located at the designated monitoring station. The performance specification of HVS shall
comply with the standard method “Determination of Suspended Particulate
Matter in the Atmosphere (High Volume Method)” as stipulated in US EPA
Standard Title 40, Code of
Federation Regulations Chapter 1 (Part 50 Appendix B).
The HVS is fitted with a conditioned, pre-weighed filter paper,
at a controlled rate. After sampling for
1 hour or 24 hours, the filter paper
with retained particles shall be collected and returned to the laboratory for
the testing of TSP levels. Continuous
1-hour and 24-hour TSP levels shall be calculated from the ratio of the mass of
particulates retained on the filter paper to the total volume of air
sampled. The analysis process shall
normally take about two days to complete.
HVS in compliance with the following specifications
shall be used for carrying out 24-hour TSP monitoring:
·
0.6 -
1.7 m3 per minute (20 - 60 standard cubic feet per minute)
adjustable flow range;
·
equipped
with a timing/ control device with ± 5 minutes accuracy for 24 hours operation;
·
installed
with elapsed-time meter with ± 2 minutes accuracy for 24 hours operation;
·
capable
of providing a minimum exposed area of 406 cm2 (63 in2);
·
flow
control accuracy: ± 2.5% deviation over 24-hour sampling period;
·
incorporated
with an electronic mass flow rate controller or other equivalent devices;
·
equipped
with a flow recorder for continuous monitoring;
·
provided
with a peaked roof inlet;

·
capable
of operating continuously for a 24-hour period.
The ET shall provide the monitoring equipment, and ensure that sufficient number of HVS with
appropriate calibration kit is available for carrying out the baseline, regular impact monitoring and ad-hoc
monitoring. The HVS shall be equipped
with an electronic mass flow controller and be calibrated against a traceable
standard at regular intervals, in
accordance with requirements stated in the manufacturers operating manual. All the equipment,
calibration kit, filter papers, etc,
shall be clearly labelled.
The flow rate of each HVS with mass flow controller
shall be calibrated using an orifice calibrator. Initial calibration of the dust monitoring
equipment shall be conducted upon installation and prior to commissioning. Five-point calibration shall be carried out
every two months. The transfer standard
shall be traceable to the internationally recognised primary standard and be
calibrated annually. The concern parties
such as IEC shall properly document the calibration data for future
reference. All the data shall be
converted into standard temperature and pressure condition.
The flow-rate of the HVS before and after the
sampling exercise with the filter in position shall be verified to be constant
and be recorded on the data sheet.
If the ET proposes to use a direct reading dust meter
to measure 1-hour TSP levels, he
shall submit sufficient information to the ER and IEC to prove that the
instrument is capable of achieving a comparable result to the HVS. The instrument shall also be calibrated
regularly, and the 1-hour sampling
shall be determined periodically by the HVS to check the validity and accuracy
of the results measured by direct reading method.
3.4.1
Laboratory Measurement/ Analysis
A clean laboratory with constant temperature and
humidity control, and equipped with
the necessary measuring and conditioning instruments to handle the dust samples, shall be available for sample analysis and
equipment calibration and maintenance.
The laboratory shall be either a HOKLAS-accredited or an internationally
accredited laboratory.
If a site laboratory is set up or a non-HOKLAS
accredited laboratory is hired for carrying out the laboratory analysis, the laboratory equipment shall be approved by the
ER and the measurement procedures shall be witnessed by the IEC. Any measurement performed by the laboratory
shall be demonstrated to the satisfaction of the ER and IEC. IEC shall regularly audit the measurement
performed by the laboratory to ensure the accuracy of measurement results. The ET Leader shall provide the ER with one
copy of the Title 40 of the Code of
Federal Regulations, Chapter 1 (Part
50), Appendix B for his
reference.
Filter paper of size 8”x10” shall be labelled before
sampling. It shall be a clean filter
paper with no pin holes, and shall
be conditioned in a humidity controlled chamber for over 24-hr and be
pre-weighed before use for the sampling.
After sampling,
the filter paper loaded with dust shall be kept in a clean and tightly sealed
plastic bag. The filter paper is then returned to the laboratory for
reconditioning in the humidity controlled chamber followed by accurate weighing
by an electronic balance with a readout down to 0.1 mg. The balance shall be regularly calibrated
against a traceable standard.
All the collected samples shall be kept in a good
condition for 6 months before disposal.
3.5
Monitoring
Frequency
3.5.1
Baseline Monitoring
Baseline monitoring shall be carried out to determine
the ambient 24-hour and 1-hr TSP levels at the designated monitoring stations
prior to the commencement of the construction works. Continuous 24-hour TSP monitoring and 3 sets
of 1-hour TSP monitoring shall be carried out daily for a period of at least
two weeks. General meteorological
conditions and notes regarding any significant adjacent dust producing sources
shall also be recorded throughout the baseline monitoring period.
Before commencing the baseline monitoring, the ET
shall inform the Contractor, ER, IEC
and EPD of the baseline monitoring schedule such that relevant parties may
conduct on-site audit of the baseline monitoring.
During the baseline monitoring,
there shall not be any construction or dust generating activities in the
vicinity of the monitoring stations.
In case the baseline monitoring could not be carried
out at the designated monitoring location during the baseline monitoring period, the ET shall carry out the monitoring at alternative
location which could effectively represent the baseline conditions at the
impact monitoring locations. The
alternative baseline monitoring location shall be agreed with the ER, IEC and
EPD.
In exceptional cases,
when insufficient baseline monitoring data or questionable results are obtained, the ET shall liaise with the ER, IEC and EPD to
agree on an appropriate set of data to be used as a baseline reference.
The baseline monitoring shall provide data for the
determination of the appropriate Action Levels with the Limit Levels set
against statutory or otherwise agreed limits.
3.5.2
Impact Monitoring
The ET shall carry out impact monitoring throughout
the construction works. 24-hour TSP
monitoring shall be conducted at least once in every six days at all the
designated monitoring stations. For
1-hour TSP monitoring, the sampling
frequency of at least three times in every six-days shall be undertaken when
the highest dust impact occurs. Before
commencing the monitoring, the ET shall inform the IEC of the monitoring
schedule such that the IEC can conduct on-site audit to ensure accuracy of the
monitoring results.
The specific time to start and stop the 24-hour TSP
monitoring shall be clearly defined for each location and be strictly followed
by the operator.
In case of non-compliance with the air quality
criteria, more frequent monitoring, as specified in the EAP shall be conducted.
This additional monitoring shall be continued until
the excessive dust emission or the deterioration in air quality is rectified.
3.6
Environmental
Compliance and EAP
The baseline monitoring results form the basis for
determining the A/L Levels for the impact monitoring. The ET shall compare the impact monitoring
results of 24-hour TSP and 1-hour TSP against the agreed A/L Levels as listed
in Table 3.2.

NOISE
4.1
Introduction
The requirements, methodology, equipment, monitoring
locations, criteria and protocols for the monitoring and audit of noise impacts
during construction of the Project are presented in this section. Noise monitoring is required during the
construction phase of the River Modification Works. The mitigation measures recommended to control
noise impacts are summarised in Annex A.
4.2
Methodology and
Criteria
Noise measurements should be carried out in
accordance with the guidelines given in Annex
– General Calibration and Measurement Procedures of Technical Memorandum on Noise from Construction Work other than
Percussive Piling (GW-TM).
Whilst the Noise
Control Ordinance (NCO) does not
provide for the statutory control of construction activities occurring on
weekdays during normal working hours (ie Monday to
Saturday inclusive 0700-1900 hours), a daytime standard of Leq(30min)
75dB(A) as stipulated in Annex 5 of the Technical
Memorandum on Environmental Impact Assessment Process (EIAO-TM) will be adopted as the noise criterion for all residential
dwellings; while a daytime standard of Leq(30min)
70dB(A) will be adopted for all educational institutions during normal school
days and Leq(30min) 65dB(A)
during examination periods.
The construction noise levels
will be measured in terms of A-weighted equivalent continuous sound pressure level (Leq)
measured in decibels dB(A). Leq(30min) should be used as the
monitoring parameter for the time period between 0700-1900 hours on normal
weekdays.
Supplementary information for data auditing, two
statistical sound levels L10
and L90; the levels
exceeded for 10 and 90 percent of the time respectively, should also be recorded
during the monitoring for reference. A
sample data record sheet is shown in Annex C for reference.
Noise measurements should generally not be made in
the presence of fog, rain, wind with a steady speed exceeding 5m s-1
or wind with gusts exceeding 10m s-1. The wind speed should be checked with a
portable wind speed meter capable of measuring the wind speed in ms-1.
4.3
Monitoring
Equipment
As referred to the GW-TM, sound level
meters in compliance with the International
Electrotechnical Commission Publications 651:1979
(Type 1) and 804:1985 (Type 1) Specifications should be used for carrying
out the noise monitoring. Immediately
prior to and following each noise measurement the accuracy of the sound level meter should 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 levels
from before and after the noise measurement agree to within 1.0 dB.
The ET should ensure that the equipment is maintained
in a good working order in accordance with the manufacturer's recommendations
with sufficient spare equipment available in the event
of breakdown to maintain the planned monitoring programme.
The ET is responsible for the provision of the
monitoring equipment and will ensure that sufficient noise measuring equipment
and associated instrumentation are available for carrying out the baseline
monitoring and impact monitoring. All
the equipment and associated instrumentation will be clearly labelled.
4.4
Monitoring
Locations
Representative locations were selected to monitor the
noise levels from the construction
of the Project. The noise monitoring
stations are listed in Table 4.1 and
presented in Figure 3.1.
Table 4.1 Noise
Monitoring Stations
for Construction Noise

|
The status and locations of noise sensitive receivers
(NSRs) may change after issuing this Manual and the
location of the noise monitoring station may need to be adjusted
accordingly. If such changes occur, the
ET should propose an updated monitoring location for the agreement from the ER,
IEC and EPD.
When alternative monitoring location is proposed, the
following criteria, as far as practicable, should be followed:
·
At
locations close to the major site activities which are likely to have noise
impacts;
·
Close
to the NSRs; and
·
For
monitoring locations located in the vicinity of the NSRs,
care should be taken to minimise disturbance to the occupants during
monitoring.
The monitoring station will normally be at a point 1m
from the exterior of the NSR building façade and at a height of approximately
1.2m above ground or at the height that has the least obstructed view of the
construction activities in relation to the NSR.
If access to the normal monitoring position cannot be obtained, an
alternative position will be chosen, and a correction to the measurements
should be made, if appropriate. For
instance, a correction of +3 dB(A) should be made to free-field
measurements. The ET should agree with
the ER, IEC, EPD and the owners/occupants of the premises on the monitoring
position. Once the positions for the
monitoring stations are chosen, the baseline monitoring and the impact
monitoring should be carried out at the same positions.
4.5
Baseline
Monitoring
The ET should carry out baseline noise monitoring
prior to the commencement of any construction works. The baseline monitoring shall be measured for
a continuous period of at least 14 consecutive days at a minimum logging
interval of 30 minutes for day-time and 15 minutes (as three consecutive Leq(5min) readings) for evening, holidays and night-time.
Before commencing the baseline monitoring, ET shall
inform the Contractor(s), IEC, ER and the EPD of the baseline monitoring
schedule programme such that relevant parties could conduct on-site audit to ensure
accuracy of the baseline monitoring results.
During the baseline monitoring, there should not be
any construction activities in the vicinity of the monitoring stations. Any non-Project related construction
activities in the vicinity of the stations during the baseline monitoring
should be noted and the source(s) and location(s) be recorded.
In case the baseline monitoring could not be carried
out at any of the designated monitoring locations during the baseline
monitoring period, the ET shall carry out the monitoring at alternative
location which could effectively represent the baseline conditions at the
impact monitoring locations. The
alternative baseline monitoring locations shall be agreed with the ER, Contractor(s)
and IEC and approved by EPD.
In exceptional cases, when insufficient baseline
monitoring data or questionable results are obtained, the ET shall liaise with
the ER, IEC and EPD to agree on an appropriate set of data to be used as a
baseline reference.
4.6
Impact Monitoring
Noise monitoring shall be carried out at all the
designated monitoring stations. An
initial guide on the monitoring is to obtain one set of 30-minute measurement
at each station between 0700 and 1900 hours on normal weekdays at a frequency
of once a week when construction activities are underway.
If construction works are extended to include works
during the hours between 1900 and 0700 hours of the following day, or on
general holidays and Sundays, applicable Construction Noise Permits (CNPs) will be obtained by the Contractor(s) under the NCO requirements, and the frequency and
scope of monitoring will be determined by EPD in the capacity of the Noise Control Authority (NCA).
4.7
Environmental
Quality Performance Limits
A/L Levels
provide an appropriate framework for the interpretation of monitoring
results. Interpretation of monitoring
results is undertaken through checking them against the A/L Levels defined in Table
4.2.

periods.
(b)
If works are to be carried out during restricted hours,
the conditions stipulated in the construction noise permit issued by the NCA
have to be followed.
|
To account for cases where ambient noise levels, as identified by baseline monitoring,
approach or exceed the stipulated Limit Level
prior to commencement of construction, a Maximum Acceptable Impact Level, which incorporates the baseline noise level and the identified construction noise Limit Level, might be defined upon agreement with the
EPD. This amended level will, therefore, be greater than 75 dB(A) and
will represent the maximum acceptable noise level
at a specific monitoring station.
For compliance checking, after taking into account
any adjustments agreed with EPD, comparison with either the Limit or the
Maximum Acceptable Impact Level will
represent the governing criteria for noise impact assessment during impact
monitoring.
4.8
Event and Action
Plan
The ET should compare the impact monitoring results
with the noise criteria as defined in Table
4.2. In cases where exceedance of these criteria occurs, actions should be
carried out in accordance with the EAP shown in Table 4.3.

Audit
Requirements
It is necessary to undertake regular environmental
audits and site inspections to ensure those recommended mitigation measures
were properly implemented. The
requirements of the environmental audit programme were set out in Section 10 of the Manual.
The audit programme will verify the implementation
status and evaluate the effectiveness and stability of the mitigation measures.

Water Quality
5.1
Introduction
This section presents details of the water quality monitoring to
be undertaken during the construction and operation of the Project. Water quality assessment carried out for the
EIA indicates that the potential water quality impacts associated with the
construction and operation of the Project will be within acceptable levels and
no adverse water quality impacts are expected.
However, the monitoring programme is designed to verify the predictions
of the EIA and ensure compliance with the assessment criteria.
In accordance with the recommendations of the EIA, mitigation measures
have been proposed during the construction and operation phases of the
Project. Details of the mitigation
measures are presented in Annex A - Implementation Schedule.
5.2
Construction
Phase
5.2.1
General
Based on the construction
methodology, the sediment will be excavated in dry within cofferdam. Water quality monitoring is thus recommended during
the foundation pit drainage and cofferdam demolition activities where there is
a potential for the release of suspended solids (SS).
Water quality assessment for
the construction phase of the Project indicates that the above construction
activities may potentially lead to dispersion of suspended sediments to area
downstream of the Project Site and hence causing elevated concentration of SS
in river water. However, the level of SS
is predicted to be within acceptable levels (SS concentrations
caused by construction activity at 500 m upstream and 1,000 m downstream of the
work area would be less than 130% of baseline SS concentrations ) and will not
lead to any adverse water quality impacts to the identified water sensitive
receivers (WSRs).
The Water Quality Impact Monitoring which will be undertaken during
construction of the Project will be designed to verify these predictions.
In addition to the Water Quality Impact
Monitoring, Baseline Water Quality Monitoring will also be undertaken for the
Project to determine the Action and Limit Levels for the monitoring programme.
5.2.2
Water Quality Impact
Monitoring
During construction phase of the Project,
Water Quality Impact Monitoring will be undertaken at the following locations
when construction works mentioned in Section
5.2.1 above are in progress:
During Foundation Pit Drainage and
Cofferdam Demolition at Work Area I and Work Area II
·
500 m
upstream of Work Area I; and
·
1,000
m downstream of Work Area II.
During Foundation Pit Drainage and
Cofferdam Demolition at Work Area III and Work Area IV
·
500 m
upstream of Work Area III; and
·
1,000
m downstream of Work Area IV.
There will be one monitoring station at
each location (ie a total of four monitoring
stations). Monitoring will be conducted
for three times per week during the construction period. The interval between two sampling surveys
will not be less than 36 hours. During
each sampling survey, water samples for laboratory analysis and in situ measurements will be taken at
all monitoring stations for the following water quality parameters:
·
Dissolved
Oxygen (mg L-1) (in situ);
·
pH (in situ);
·
Turbidity
(NTU) (in situ); and
·
Suspended
Solids (mg L-1) (laboratory analysis).
Duplicate water samples and in situ measurements of the above parameters will be taken at mid-depth
of each station during a sampling survey.
In addition to the above water quality parameters, other relevant data
will also be measured and recorded in the Water Quality Impact Monitoring Logs,
including the location of the sampling stations, water depth, time, weather
conditions, special phenomena and work activities undertaken around the
monitoring and works area that may influence the monitoring results.
Upon completion of all construction activities, a post-project
water quality monitoring will be carried out for four weeks in the same manner
as the Water Quality Impact Monitoring.
5.2.3
Baseline Water Quality Monitoring
Baseline Water Quality Monitoring will be
conducted for a period of four weeks prior to the commencement of construction
works mentioned in Section 5.2.1
above in order to gather representative water quality data for the EM&A
programme. Location and number of
baseline monitoring stations will be the same as the Water Quality Impact
Monitoring.
Baseline Water Quality Monitoring will be
undertaken for three days per week at all stations. The interval between two sampling surveys
will not be less than 36 hours.
The following suite of parameters will be
measured as part of the Baseline Water Quality Monitoring:
·
Dissolved
Oxygen (mg L-1) (in situ);
·
pH (in situ);
·
Turbidity
(NTU) (in situ); and
·
Suspended
Solids (mg L-1) (laboratory analysis).
Duplicate water samples and in situ measurements of the above parameters will be taken at
mid-depth of each station during a survey.
In addition to the above water quality parameters, other relevant data
will also be measured and recorded in the Baseline Water Quality Monitoring,
including the location of the sampling stations, water depth, time, weather
conditions, special phenomena and work activities undertaken around the
monitoring and works area that may influence the monitoring results.
5.2.4
Water Quality Compliance and Event &
Action Plan
Results of the Water Quality Impact
Monitoring will be evaluated against Action and Limit Levels. Suspended solids (SS) will be the key
parameter under evaluation and Action and Limit Levels will be determined for
this parameter. However, turbidity and
dissolved oxygen can also provide valuable instantaneous information on water
quality and thus Action and Limit Levels are measured for these parameters to
facilitate quick responsive action in the event of any apparent unacceptable
deterioration attributable to the works.
The Action and Limit Levels for SS,
turbidity and dissolved oxygen will be determined according to the criteria
shown in Table 5.1. Action and Limit Levels are used to determine
whether modifications are necessary to mitigate impacts to water quality. In the event that the levels are exceeded,
appropriate actions in the Event and Action Plan (Table 5.2) should be undertaken.

Equipment
The following equipment will be supplied
and used by the contractor for the water quality monitoring:
·
Positioning
Device - A hand-held digital Global Positioning System
(GPS) with way point bearing indication or other equivalent instrument of
similar accuracy will be provided and used during monitoring to ensure the
monitoring team is at the correct location before taking measurements.
·
Dissolved
Oxygen and Temperature Measuring Equipment - The instrument will
be a portable, weatherproof dissolved oxygen measuring instrument complete with
cable, sensor, comprehensive operation manuals, and will be operable from a DC
power source. It will be capable of
measuring: dissolved oxygen levels in the range of 0 - 20 mg L-1 and
0 - 200% saturation; and a temperature of 0 - 45 degrees Celsius.
It
will have a membrane electrode with automatic temperature compensation complete
with a cable. Sufficient stocks of spare
electrodes and cables will be available for replacement where necessary (for
example, YSI model 59 metre, YSI 5739 probe, YSI 5795A submersible stirrer with
reel and cable or an approved similar instrument).
·
Turbidity

pH
meter – A portable pH meter capable of
measuring a range between 0.0 and 14.0 will be provided to measure pH in marine
waters.
·
Water
Sampler- A
water sampler (eg Kahlsico
Water Sampler), which is a transparent PVC cylinder (capacity not less than 2
litres) and can be effectively sealed with latex cups at both ends, will be
used for sampling. The sampler will 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. Water samples for suspended solids
measurement will be collected in high density polythene bottles, packed in ice
(cooled to 4 ºC without being frozen), and delivered to the
laboratory in the same day as the samples were collected.
·
Water
Depth Gauge - A portable, battery-operated echo
sounder will be used for the determination of water depth at each designated
monitoring station.
5.2.6
Sampling / Testing Protocols
All in situ monitoring
instruments will be checked, calibrated and certified by a laboratory
accredited under HOKLAS or any other international accreditation scheme before
use, and subsequently re-calibrated at three month intervals throughout the
stages of the water quality monitoring.
Responses of sensors and electrodes will be checked with certified
standard solutions before each use.
On-site calibration of field equipment
will follow the “Guide to Field and
On-Site Test Methods for the Analysis of Waters”, BS 1427: 1993. Sufficient stocks of spare parts will be
maintained for replacements when necessary.
Backup monitoring equipment will also be made available so that
monitoring can proceed uninterrupted even when equipment is under maintenance,
calibration etc.
Water
samples for SS measurements will be collected in high density polythene
bottles, packed in ice (cooled to 4° C without being
frozen), and delivered to a HOKLAS laboratory as soon as possible after
collection.
5.2.7
Laboratory Procedures
The
analytical techniques to be adopted for this Project must conform to HOKLAS (or
similar overseas) accreditation. Using
chain of custody forms, collected water samples will be transferred directly to
laboratory for immediate processing.
Laboratory analysis for SS will started within 24 hours after collection
of water samples.
5.2.8
QA/QC
Field Logs
Field
logs will be maintained for all survey work, noting the date of the survey,
equipment used, survey manager and a record of all activities and
observations. Field logs will be
retained for the duration of the Project and archived on completion.
In
situ measured data will be digitally recorded
from the instruments and converted into Microsoft Excel format, or manually
noted. Both disc copy and hard copy will
be retained for the file records. Any
deviation from the standard procedure will be noted in the log and the reason
for the deviation recorded. In addition,
field logs will contain notes of events or activities in the vicinity of the
monitoring location which might give rise to anomalous data being recorded.
Sampling
The
Contractor will record all data from in situ testing and from any
analysis carried out in a Field Log. All
samples will be identified with a unique date/time/location/depth/sample-type
code which will be attached to the sample container or written in indelible ink
directly on the container. In order to
avoid contamination of the samples, all containers will be new and unused and
of analytical grade quality. Sources of
contamination will be isolated from the working area and any sample
contaminated by local material will be discarded and the sampling
repeated.
Measurement Procedures
All
in situ monitoring instruments will be checked, calibrated and certified
and subsequently re-calibrated at three monthly intervals throughout all stages
of the water quality monitoring, or as required by the manufactures
specification. Certificate(s) of
Calibration specifying the instrument will be attached to the monitoring
reports.
Transport of Samples
All
samples transferred from one sub-contractor to another will be accompanied by
Chain of Custody (COC) forms. Any
missing or damaged samples require notification to ET Leader following logging
in the laboratory QA system. The number
of samples, the parameters to be tested and the time of delivery should be
clearly stated on the COC forms to ensure that samples are analysed for the
correct parameters and suitable time is provided to the analytical laboratory
for provision of resources required in the analyses.
5.3
Operation Phase
Adverse water quality impact is not expected during operation phase and
hence monitoring is not considered necessary.
In fact the water quality will be monitored through the existing
monitoring programme along Shenzhen River.

Ecology
6.1
Introduction
In
accordance with the recommendations of the EIA, good construction practices
have been proposed during the construction of the Project. Details of the good practices are presented
in Annex A
- Implementation Schedule. Regular site inspections during the construction phase will confirm the
implementation of these practices and the adaptation of ecological design in the
landscape work after the completion of construction.
6.2
Construction
Phase
No ecological mitigation measures apart from the
adoption of good construction practise are required to be checked as part of
the EM&A procedures during the construction phase. The list of good construction practices is
provided in Annex A.
6.3
Operation Phase
The completed landscape works adopting ecological
design on the Hong Kong side will be monitored
during the one year establishment period.
Although no adverse residual impacts are envisaged
based on the results of impact assessment, wetland dependent bird monitoring
for one year is recommended after the establishment of the landscape plantings
of the Project. The purpose of the
operation monitoring is to review the performance of the reprovisioned/reinstated
habitats. Particular focus will be made
on bird species of conservation interest (especially ardeid
species including Chinese Pond Heron, Black-crowned Night Heron, Grey Heron,
Great Egret, Intermediate Egret and Little Egret, and two wetland dependant
species Common Teal and White-breasted Waterhen).
Standard, quantitative point count surveys will be
undertaken at designated sampling locations at once per month after the establishment
of the landscape plantings of the Project.
The necessity for further ecological monitoring would be reviewed after
the first year ecological monitoring programme.
Locations of sampling transects shall include reprovisioned/reinstated
habitats including riverbank landscape areas, floodplains and watercourse, and
other reference locations within Hong Kong
boundary. Details of the monitoring
programme will be formulated and further submitted under the Project.

Waste Management
7.1
Introduction
The Project is expected to generate the following
types of waste during the construction phase:
·
Dredged
river sediment;
·
Construction
and demolition (C&D) materials;
·
Chemical
waste;
·
Sewage;
and
·
General
refuse.
Dredged river sediment will be generated from maintenance
dredging during the operation phase.
Mitigation measures, where appropriate, have been
recommended in the EIA Report to avoid
or reduce potential adverse environmental impacts associated with handling,
collection and disposal of waste arising from the construction and operation of
the Project.
Waste management will be the Contractor(s)’s
responsibility and wastes produced during the construction phase will be
managed in accordance with appropriate waste management practices and EPD’s regulations and requirements.
Auditing of waste management practices during regular
site inspections will confirm that these solid and liquid wastes generated
during construction are not disposed of into the surrounding stormwater drains/river.
The Contractor(s) will be responsible for the implementation of any
mitigation measures to reduce waste or redress issues arising from the waste
materials.
7.2
Waste Management
Practices
The Contractor(s) shall incorporate the recommended
mitigation measures into a Waste Management Plan (WMP) for managing the
different types of wastes on site. The
Contractor(s) shall submit the WMP to DSD and the Engineer for approval prior
to the commencement of the construction works.
The WMP will be prepared and implemented in accordance with ETWB TC(W) No. 19/2005 and shall be
certified by the ET Leader and verified by the IEC as conforming to the
information and recommendations contained in the Waste Management Impact Assessment and this Manual.
The WMP shall describe the arrangements for
avoidance, re-use, recover and recycling, storage, collection, treatment and
disposal of different categories of waste to be generated from construction
activities and shall include the recommended mitigation measures on waste
management detailed in Annex A of this
Manual. The WMP shall indicate the
disposal location(s) of all surplus excavated spoil and other wastes.
Prior to the commencement of dredging activities, the
disposal strategy for the dredged sediment shall be determined in accordance
with the ETWB TC(W) No. 34/2002: Management of Dredged/Excavated Sediment.
A Trip Ticket system shall be included in the
WMP. Surplus excavated spoil and other
wastes shall not be disposed of 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 (see Annex A) provides details on
the appropriate mitigation measures for avoiding and preventing adverse
environmental impacts associated with dredged river sediment, C&D
materials, chemical wastes, general refuse and sewage from the workforce. The WMP shall be refined and updated as more
detailed information is generated on the volume of dredged river sediment and
the agreed disposal arrangements.
Similarly, it should 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 shall also outline the requirements for a
waste audit programme to verify that the measures outlined in the plan are
effectively implemented and adhered too.
7.3
Waste Management
EM&A
To facilitate monitoring and control over the
contractors’ performance on waste management, a waste inspection and audit
programme will be implemented throughout the construction phase. The programme shall look at the aspects of
waste management including waste generation, storage, recycling, transport and
disposal. An appropriate audit programme
shall be undertaken with the first audit conducted at the commencement of the
construction works.
The aims of the waste inspection and audit programme
are:
·
To
review the Contractor’s WMP including the quantities and types of C&D
materials generated, reused on-site 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 in an environmentally acceptable manner and comply
with the relevant requirements under the Waste
Disposal Ordinance (WDO) and its regulations;
·
To
confirm that the Contractor(s) properly implements the appropriate
environmental protection and waste pollution control mitigation measures, as
outlined in the Implementation Schedule (see 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(s) on deficiencies identified.
Joint site inspections and audits by the ET, IEC and Contractor(s) shall
be undertaken each month. Particular
attention will be given to the Contractor(s)’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 shall be visually inspected. The public fill for delivery to the
government public fill reception facilities shall contain no observable
non-inert materials (e.g. general refuse, timber, etc). As a good practice, the waste to be disposed
of at landfills should minimise any inert or reusable/recyclable C&D
materials (e.g. soil, broken rock, metal, and paper/cardboard packaging, etc). Any irregularities observed during the site
audits will be raised promptly to the Contractor(s) for rectification.
The findings of the waste audits will be reported in
the Monthly EM&A Reports.
7.3.1
Methodology and Criteria
The 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 Contractor(s)
shall 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 Schedule contained in Annex A of this Manual, and defined below:
General Legislation

Cultural Heritage
8.1
Introduction
In
accordance with the recommendations of the EIA, mitigation measure has been proposed
during the construction phase of the Project where applicable.
8.2
Archaeology
The archaeological survey
identified only the secondary archaeological deposits at Chuk
Yuen and Pak Fu Shan sections (i.e. Sections 2 and 4) of the Project. The chance of finding in situ archaeological
deposits is very low. Thus no impact on
significant archaeological resources is anticipated and no archaeological monitoring is required. Other sections (i.e. Sections 1, 3 and 5)
have been identified with no archaeological potential where no impact is
anticipated. Thus no archaeological
monitoring is required. Pursuant to the
Antiquities and Monuments Ordinance, the project proponent should inform the
AMO immediately in case of discovery of antiquities or supposed antiquities in
the course of soil excavation works in construction stage.
However, it should be noted that the archaeological
impact assessment covered only the works area assigned as at the date of this
report. If the works boundary changes in
later stage to cover additional area not covered in the EIA, the need for
further archaeological survey and subsequent impact assessment should be
reviewed and AMO should be consulted.
8.3
Built
Heritage
As no direct or indirect
impacts on the identified built heritage sites are anticipated due to their
large separation distance from the Project Site, no mitigation measures are
considered necessary. As such, no built
heritage monitoring and audit is required.
9
Landscape & visual
9.1
Introduction
The EIA has recommended that checking of
implementation of the mitigation measures for landscape and visual resources
shall be undertaken as part of the site inspections. The implementation and maintenance of
mitigation measures (see Annex A) shall be checked
to confirm that they are fully realised and that potential conflicts between
the proposed landscape measures and any other project works and operational
requirements are resolved at the earliest practical date and without compromise
to the intention of the mitigation measures.
9.2
Construction
Phase
In
accordance with the recommendations of the EIA, landscape and visual mitigation
measures have been proposed during the construction phase of the Project. Details of the mitigation measures are
presented in Annex A - Implementation
Schedule which shall be
checked as part of the EM&A procedures during the construction phase.
9.3
Operation Phase
The completed landscape works adopting ecological

Environmental Site Inspection
10.1
Site Inspections
Site inspections provide a direct means to assess and
confirm that the Contractor(s)’s environmental protection and pollution control
measures are in compliance with the contract specifications. The site inspection shall be undertaken
routinely by the ET to verify that appropriate environmental protection and
pollution control mitigation measures are properly implemented in accordance with
the EIA. In addition, the ET shall be
responsible for defining the scope of the inspections, detailing any
deficiencies that are identified, and reporting any necessary action or
additional mitigation measures that were implemented as a result of the
inspection.
Regular site inspections shall be carried out by the
ET each month. The IEC shall also
undertake monthly site audit to assess the performance of the
Contractor(s). The areas of inspection
shall not be limited to the site area and shall also include the environmental
conditions outside the site which are likely to be affected, directly or
indirectly, by the site activities. The
ET shall make reference to the following information while conducting the
inspections:
·
the
EIA and EM&A recommendations on environmental protection and pollution
control mitigation measures;
·
ongoing
results of the EM&A programme;
·
work
progress and programme;
·
individual
works methodology proposals;
·
the
contract specifications on environmental protection;
·
the relevant
environmental protection and pollution control laws; and
·
previous
site inspection results.
The Contractor(s) shall update the ET with relevant
information on the construction works prior to carrying out the site
inspections. The site inspection results
shall be submitted to the IEC, DSD and the Contractor(s) within 24 hours. Should actions be necessary, the ET shall
follow up with recommendations on improvements to the environmental protection
and pollution control works and shall submit these recommendations in a timely
manner to the IEC, DSD and the Contractor(s).
They shall also be presented, along with the remedial actions taken, in
the monthly EM&A Report. The
Contractor(s) shall follow the procedures and time frame stipulated in the
environmental site inspection for the implementation of mitigation proposal and
the resolution of deficiencies in the Contractor(s)’ EMS. An action reporting system shall be
formulated and implemented to report on any remedial measures implemented
subsequent to the site inspections.
Ad hoc site inspections shall also be carried
out by the ET and site audits by the IEC if significant environmental issues
are identified. Inspections and audits
may also be required subsequent to receipt of an environmental complaint or as
part of the investigation work as specified in the EAPs
for EM&A programme.
10.2
Compliance with
Legal & Contractual Requirements
There are contractual environmental protection and
pollution control requirements as well as environmental protection and pollution
control laws in Hong Kong with which the
construction activities will comply.
In order that the works are in compliance with the
contractual requirements, the works method statements submitted by the
Contractor(s) to DSD for approval will be sent to the ET for review.
The ET shall also review the progress and programme
of the works to check the regulatory compliance.
The Contractor(s) shall regularly copy relevant
documents to the ET so that the checking and auditing work can be carried
out. The relevant documents are expected
to include at a minimum the updated Work Progress Reports, the updated Works
Programme, the application letters for different licence/permits under the
environmental protection laws and all valid licences/permits. The site diary
shall also be available for the ET inspection upon request.
After reviewing the document, the ET shall advise the
IEC, DSD and the Contractor(s) of any non-compliance from the contractual and
legislative requirements on environmental protection and pollution control for
follow-up actions. The ET shall also
advise the IEC, the Contractor(s) and DSD on the current status on
licence/permit applications and any environmental protection and pollution
control preparation works that may not be suitable for the works programme or
may result in potential nonconformity of environmental protection and pollution
control requirements.
Upon receipt of the advice, the Contractor(s) shall
undertake immediate action to remedy the situation. The ET, IEC and DSD shall follow up to
confirm that appropriate action(s) shall be taken by the Contractor(s) in order
that the environmental protection and pollution control requirements are
fulfilled.
10.3
Environmental
Complaints
The ET shall undertake the following
procedures upon receipt of a complaint:
(i) log complaint and date of receipt into the
complaint database and inform the IEC immediately;
(ii) investigate the complaint and discuss with the Contractor(s) and
DSD to determine its validity and to assess whether the source of the issue is
due to works activities;
(iii) if a complaint is considered valid due to
the works , the ET will identify mitigation measures in consultation with the
Contractor(s), DSD and IEC;
(iv) if mitigation measures are required, the ET shall advise the
Contractor(s) accordingly;
(v) review the Contractor(s)'s response on the identified mitigation
measures and the updated situation;
(vi) if the complaint is transferred from EPD, an interim report shall
be submitted to EPD on the status of the complaint investigation and follow-up
action within the time frame assigned by EPD;
(vii) undertake additional monitoring and audit to
verify the situation if necessary and confirm that any valid reason for
complaint does not recur;
(viii) report the investigation results and the
subsequent actions on the source of the complaint for responding to
complainant. If the source of complaint
is EPD, the results shall be reported within the time frame assigned by EPD;
and
(ix) record the complaint, investigation, the subsequent actions and
the results in the monthly EM&A Reports.
During the complaint investigation work, the ET,
Contractor(s) and DSD shall cooperate with the IEC in providing the necessary
information and assistance for completion of the investigation. If mitigation measures are identified in the
investigation, the Contractor(s) shall promptly carry out the mitigation
measures. DSD will approve the proposed
mitigation measures and the ET and IEC shall check that the measures have been
carried out by the Contractor(s).
10.4
Log-Book
The ET Leader shall keep a contemporaneous log-book
of each and every instance or circumstance or change of circumstances which may
affect the environmental impact assessment and every non-compliance from the
recommendations of the EIA Report or the conditions of the EP. The ET Leader shall 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 shall be kept readily
available for inspection by persons assisting in supervision of the
implementation of the EIA Report recommendations (such as DSD, IEC and
Contractor(s)) and the EPs or by EPD or his authorised officers.
