Introduction
1.1
Purpose of The
Manual
This Environmental Monitoring and Audit
(EM&A) Manual (“the Manual”) has been prepared by ERM-Hong Kong, Limited (ERM) on behalf of Sha Lo Tung Development Company Ltd
(SLTDC). The
Manual is a submission as part of the Environmental Impact Assessment (EIA)
Study of the Pilot Project for Public –
Private Partnership Conservation Scheme, Sha Lo Tung
Valley, Tai Po
(hereafter referred to as “the Project”).
The Manual has been prepared with
reference to the EIA Study Brief (No. ESB-206/2009)
and 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 the construction and operation phases of the Project. It provides systematic procedures for monitoring
and auditing of the potential environmental impacts that may arise from the
Project.
1.2
Project Description
1.2.1
The Case for Nature Conservation
The New Nature
Conservation Policy (NNCP) of the Government aims at regulating, protecting and
managing natural resources that are important for the conservation of
biological diversity of Hong Kong in a
sustainable manner, taking into account social and economic considerations, for
the benefit and enjoyment of the present and future generations of the community.
One of the objectives of the NNCP is to
enhance conservation of ecologically important sites under private
ownership. This objective can be
achieved through the present proposal by total surrender of the land with valuable
habitats in the Public-Private Partnership (PPP) site by the project proponent
to the government. This would be solely
for nature conservation purpose and a long term viable and sustainable
conservation management plan prepared and implemented by Green Power, and
associated ecological experts with proven track record in nature conservation
and education, the details of which are outlined in the Conservation Management
Plan (Annex A of the
EIA Report).
The Policy also discusses how the natural environment
provides vital resources for recreation, tourism and educational
activities. There is clear recognition
that providing opportunities for Hong Kong
people to participate in these conservation-led activities is increasingly
important as urbanization continues.
1.2.2
The Project
The Project includes three inter-related components:
Ecological Reserve, Development Site and Sha Lo Tung Road Improvement (Figure 1.1). The
Proponent, the Sha Lo Tung Development Company (SLTDC) and the Conservation
Agent, Green Power (GP), propose to set up an Ecological Reserve (approximately
52.5 ha, accounting for more than 92% of the entire Valley) in Sha Lo Tung
(SLT) Valley. The SLTDC intends to
dedicate their private housing lots (approximately 0.8 ha) and private
agricultural lots (approximately 26 ha) in the Valley and agricultural lots in
the adjacent Country
Park (approximately 2 ha)
for conservation purposes and establish an Ecological Reserve on ecologically
sensitive land dedicated by SLTDC as well as government land. The Ecological Reserve will maintain,
protect, restore and enhance the ecological resources of the SLT Valley. This will be achieved by preventing
unauthorised incompatible activities, managing and restoring habitats at the
“optimal” succession state, and by enhancing grassland and woodland
habitat. Additionally, a Nature
Interpretation Centre providing nature education activities to promote awareness,
appreciation and understanding of the ecological value of the area, will be
built adjacent to the Ecological Reserve in the Development Site. The conservation management and funding of
the SLT Ecological Reserve will be overseen by the Government statutory
fund.
The Ecological Reserve, approximately 52.5 ha,
provides an opportunity to enhance Sha Lo Tung Valley’s environment for the
benefit of the community and boost its ecological value. Biodiversity conservation is the core focus
of the Public Private Partnership (PPP) programme where value-added activities
such as conservation education, will be integrated into the management strategy
of Sha Lo Tung Valley, when and where appropriate. It can be achieved by adopting a Conservation
Management Plan (CMP) which prescribes management measures to assist in
safeguarding the ecological value of the area in perpetuity for the people of
Hong Kong (Figure 1.2). A summary of the CMP is presented in the
following sections.
The Development Site of approximately 4.1 ha is
outside of the Country
Park and Conservation
Area. Besides the Nature Interpretation Centre, the Development Site
accommodates the necessary development concession in the form of a
Multi-Cultural Education Retreat cum Columbarium (with a development footprint
of approximately 1.625 ha or 39.6% of the total area of the Development Site
(includes the Nature Interpretation Centre, public parking, footpaths,
landscaping areas and associated site formation) in a lower ecological value
area at the entrance to the Valley (Figure 1.3). These concession facilities provide revenue
to payback the upfront capital injected by the SLTDC to sustain initial set up
and long term operation funding of the Ecological Reserve.
Sha Lo Tung Road Improvement also lies outside of the
Country Park and Conservation Area. The existing Sha Lo Tung Road (approximately 2.3 km)
will be upgraded to Single Track standard with the minimum required number of
passing bays to meet the requirements of the Transport Department and Fire
Services Department and provide safe public access to the Ecological Reserve,
Development Site and Country
Park.
Indicative Works Programme
The construction works are anticipated to commence
in 2011/2012. The works programme and
the work sequence of the Project will be undertaken as follows:
·
Ecological Reserve – The enhancement work will be undertaken
immediately once the commencement of the Project is confirmed in order to
provide the greatest conservation and ecological benefit. The Conservation Management Plan and the priority of the enhancement
works shall be approved by the Government statutory fund prior to the
commencement of the enhancement works.
The minor improvement to the footpath, construction and installation of
the temporary footbridge and fencing around broken village houses and
structures at Lei Uk will be completed within 3
months (during the dry season).
·
Sha Lo Tung Road Improvement – The road
improvement works will be divided into three phases. Each phase of the road works will be
constructed generally in sequence with each will take approximately 8 to 9 months
and overlap at certain periods of time.
·
Development Site – The site formation works will be carried out in
three stages after Sha Lo Tung Road Improvement: Stage 1 (approximately 6
months), Stage 2 (approximately 5 months) and Stage 3 (approximately 6 months).
The duration of each of the three stages will overlap at certain periods of
time so that the earthworks (soil and excavation and filling works) will only
be undertaken during the dry season (November to March).
1.3
Objectives of the EM&A
Programme
The potential environmental impacts
associated with the Project have been assessed and described in the EIA Report. The EIA
Report also specifies the mitigation measures required to comply with the
environmental criteria. These mitigation
measures and their implementation requirements are presented in the
Implementation Schedule (see Annex
A). The EIA recommends that an
EM&A programme be implemented to assess the effectiveness of measures and
to confirm that there will be no adverse environmental impacts during the
construction and operation of the Project.
It is also recommended that regular site audits be undertaken during
construction and operation phases to check whether good site practices are
properly implemented to prevent adverse environmental impacts. Any activities that have a potential to cause
adverse environmental impacts are identified before the adverse impacts
occurred. Ad-hoc visits to the impacted sites should also be made in response to any
complaints or reported non-compliance with environmental standards to ensure
that prompt actions are taken to address the impacts.
This Manual provides details
of the EM&A requirements that have been recommended in the EIA Report. The main objectives of the EM&A programme
are to:
·
verify the environmental impacts predicted in the EIA Report;
·
monitor the performance of the Project and the effectiveness of
mitigation measures;
·
determine Project compliance with regulatory requirements and
standards;
·
provide an early indication should any of the environmental
control measures or practices fail to achieve the required standards;
·
take remedial action if unexpected problems or unacceptable
impacts arise;
·
provide a database against which any short or long term
environmental impacts of the Project can be determined; and
·
provide data against which environmental audits
may be undertaken.

EM&A
General Requirements
2.1
Introduction
The general requirements of
the EM&A programme are described in this section. The scope of the programme is developed with
reference to the findings and recommendations of the EIA Report.
2.2
EM&A
The potential environmental
impacts and the implementation of the recommended mitigation measures for the
construction and operation of the Project should be monitored through the
EM&A programme specified in this Manual.
The EM&A programme will include
regular and ad-hoc site inspections/
audits and environmental monitoring. The
programme also include the mechanisms to review and assess the Contractor’s
environmental performance, ensuring that the recommended mitigation measures have
been properly implemented, and that timely resolution of received complaints
are managed and controlled in a manner consistent with the recommendations of
the EIA Report.
2.2.1
Environmental Monitoring
The environmental monitoring work
throughout the Project period will be carried out in accordance with this
EM&A Manual and should be carried out by the ET/CS. The monitoring should be focused on the
following aspects:
·
construction noise monitoring for two representative NSRs (N1 and N5);
·
baseline, impact, post-project and operation phase monitoring on
water quality;
·
baseline, impact, post-project and operation phase ecological
monitoring; and
·
construction archaeological monitoring and
potential vibration monitoring.
These are discussed further in
Sections 3 to 10 of
this Manual.
2.2.2
Compliance with Action and
Limit Levels
The action and limit levels should be defined for
environmental monitoring at designated monitoring locations exceeding which a
prescribed response should be required. Individual
action and limit levels should be quantitatively defined for the respective
environmental monitoring parameters according to the following basic
principles:
Action Level
Action levels indicate deteriorating ambient
environmental quality potentially due to the Project implementation. It acts as a sign to trigger stepped up
monitoring and appropriate remedial actions in order to rectify any
mal-practices or non-conformance of Project activities thereby preventing the
deterioration of environmental quality and to resume the ambient environmental
quality back to normal levels.
Limit Level
Limit levels are the statutory and/or contractual
levels below which environmental conditions are considered unacceptable. If limit levels were exceeded, the relevant
part of the works should not be continued without implementation of immediate
remedial action, including a critical review of plant and working methods.
2.2.3
Event and Action Plans
The purpose of the Event and Action Plans (EAPs) is to provide, in association with the EM&A
activities, procedures for ensuring that if any significant environmental
incident (either accidental or through inadequate implementation of mitigation
measures) on the part of the Contractor does occur, the cause should be quickly
identified and remediated, and the risk of a similar event recurring is
reduced.
2.2.4
Site Inspections/Audits
In addition to monitoring works as a means of
assessing the ongoing environmental performance of the Project, the ET/CS and
IEC should undertake site inspections and audits of on-site practices and
procedures. The primary objectives of
the site inspection and audit programme are to ensure the good site practices
and mitigation measures recommended in the EIA Report are properly
implemented and to assess the effectiveness of these measures.
The findings of site inspections and audits should be
made known to the Contractor at the time of the inspection to enable the rapid
resolution of identified non-compliances.
Non-compliances, and the corrective actions undertaken, should be
reported in the monthly EM&A reports.
Section 11 of this Manual presents details of the
scope and frequency of on-site inspections and defines the range of issues that
the audit protocols should be designed to address.
2.2.5
Enquiries, Complaints and
Requests for Information
Enquiries, complaints and
requests for information can be expected from a wide range of individuals and organisations
including members of the public, Government departments, the press and
television media and community groups.
All enquiries concerning the
environmental impacts of the Project, irrespective of how they are received,
should be reported to the PP and IEC and directed to the Contractor and ET/CS
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, PP, EPD and C 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 the IEC and EPD, undertake additional
monitoring to verify the existence and severity of the alleged complaint;
·
identify
necessary remedial measures and implement as soon as possible;
·
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 actions taken should be documented on a complaint proforma (see Annex E) and should be verified by the IEC. A formal response to each complaint received
should be prepared by the Contractor within a maximum of five working days and
submitted to the IEC, PP and EPD for review.
The PP will notify the concerned person(s) of the findings of the
complaint investigation and the actions taken, if required.
(e) 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.
In all cases the complainant will be
notified of the findings of the investigation.
2.2.6
Reporting
With respect to the identified potential impacts and
the nature and frequency of the EM&A to be undertaken, it is considered
that real-time reporting of the monitoring data through a dedicated website is
not applicable. However, the monitoring
data should be uploaded to the Project website at regular interval agreed by
the Contractor, EPD and the PP.
Monthly EM&A reports prepared by the
ET/CS should be certified by the IEC prior to submission to the Contractor,
IEC, PP and EPD. The monthly EM&A reports should be prepared and
submitted within 10 working days of the end of each reporting month. Additional details on reporting protocols are
presented in Section 12.
2.2.7
Cessation of EM&A
The cessation of EM&A programme
is subject to the satisfactory completion of the EM&A
Final Review Report, agreement with the IEC and approval from Environmental
Protection Department (EPD), Agriculture, Fisheries and Conservation Department
(AFCD) and Water
Supplies Department (WSD).

Noise
Impacts
4.1
Introduction
In accordance with the recommendations of the EIA, mitigation measures
to control impacts from noise generating works have been proposed during the
construction phase of the Project. Details
of the mitigation measures are presented in Annex A - Implementation Schedule.
4.2
Construction
Phase
4.2.1
Development Site
and Sha Lo Tung Road Improvement
Noise monitoring is recommended
to ensure compliance with the noise criterion at the NSR and the monitoring
requirements are detailed below:
Noise mointoring
is recommended at two locations to ensure compliance with the noise
criterion at the NSRs and the details are as follows:
Noise Parameters
The construction
noise level shall be measured in terms of the A-weighted equivalent continuous
sound pressure level (Leq). Leq(30 min)
shall be used as the monitoring parameter for the time period between 0700-1900
hours on normal weekdays. For all other
time periods, Leq(5 min) shall be employed for comparison with the NCO
criteria.
As supplementary
information for data auditing, statistical results such as L10 and L90 shall
also be obtained for reference. A sample
data record sheet is shown in Annex
F for reference.
Monitoring
Equipment
As referred to in
the Technical Memorandum (TM) issued under the Noise Control Ordinance (NCO), sound level meters in compliance
with the International Electrotechnical Commission Publications 651: 1979 (Type
1) and 804: 1985 (Type 1) specifications shall be used for carrying out 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
may 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 accordance with standard
acoustical principles and practices in relation to weather conditions.
Monitoring
Location
The noise
monitoring locations have been shown in Figure 4.1 The status and location of noise sensitive
receiver may change after issuing this manual.
If such cases exist, the ET Leader shall propose updated monitoring locations
and seek approval from ER and agreement from the IEC and EPD of the proposal.
When alternative
monitoring locations are proposed, the monitoring locations shall be chosen
based on the following criteria:
a) at
locations close to the major site activities which are likely to have noise
impacts;
b) close to
the noise sensitive receivers; and
c) for
monitoring locations located in the vicinity of the sensitive receivers, care
shall be taken to cause minimal disturbance to the occupants during monitoring.
The monitoring
station shall normally be at a point 1 m from the exterior of the sensitive
receiver building facade and be at a position 1.2 m above the ground. If there is a problem with access to the
normal monitoring position, an alternative position may be chosen, and a
correction to the measurements shall be made.
For reference, a correction of +3dB(A) shall be made to the free field
measurements. The ET Leader shall agree
with the IEC on the monitoring position and the corrections adopted. Once the positions for the monitoring
stations are chosen, the baseline monitoring and the impact monitoring shall be
carried out at the same position.
Impact Monitoring
Weekly noise
monitoring shall be carried out at all the designated monitoring stations to obtain
one set of 30-minute measurement between 0700-1900 hours.
General
construction work carrying out during restricted hours is controlled by CNP
system under the NCO.
In case of
non-compliance with the construction noise criteria, more frequent monitoring
as specified in the Action Plan in Table
6.2 shall be carried out. This
additional monitoring shall be continued until the recorded noise levels are
rectified or proved to be irrelevant to the construction activities.
Event and Action
Plan for Noise
The Action and
Limit levels for construction noise are defined in Table 4.1. Should
non-compliance of the noise quality criteria occur, actions in accordance with
the Action Plan in Table 4.2 shall be
carried out.

Water quality
5.1
Introduction
In accordance with the
recommendations of the EIA, mitigation measures have been proposed during the construction
and operation of the Project to ensure that the water quality at the WSRs is not impacted by the Project. Details of the mitigation measures are
presented in Annex A - Implementation Schedule.
In addition, baseline water
quality monitoring will be required prior to the commencement of construction
activities. The water quality monitoring
programme will be carried out to ensure that any
deteriorating water quality is readily detected and timely action taken to
rectify the situation.

Construction
Phase
5.2.1
Monitoring Parameters
Measurements of the parameters, as shown in Table 5.1 should be undertaken by the ET/CS at strategic locations
in Sha Lo Tung SSSI Stream (Figure 5.1). This ensures that any
deterioration of water quality will be readily detected and timely action will
be taken to rectify the situation. Since
only works within the Development Site and Phase 3 of Sha Lo Tung Road
Improvement Works have the potential to impact on the Sha Lo Tung SSSI Stream,
water quality impact monitoring will be conducted throughout the construction
period of Phase 3 of Sha Lo Tung Road Improvement works and the construction
period of the Development Site.

In association with the water
quality parameter measurements, relevant data should be recorded, including the
monitoring location, time, weather conditions, sampling water depth (m), water
flow rate (m3/day) and any special phenomena (provided with photographs if appropriate)
and work underway at the construction site.
5.2.2
Monitoring Equipment
Dissolved Oxygen and Temperature Measuring Equipment
The instrument should be a
portable, weatherproof dissolved oxygen measuring instrument complete with
cable, sensor, comprehensive operation manuals, and should be operable from a
DC power source. It should 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 should have a membrane
electrode with automatic temperature compensation complete with a cable of not
less than 25 m in length. Sufficient
stocks of spare electrodes and cable should be available for replacement where
necessary (for example, YSI model 59 meter, YSI 5739 probe, YSI 5795A
submersible stirrer with reel and cable or an approved similar instrument).
Turbidity Measuring Instrument
Turbidity should be measured
in-situ by the nephelometric method. The instrument should be portable and
weatherproof using a DC power source complete with cable, sensor and
comprehensive operation manuals. It
should have a photoelectric sensor capable of measuring turbidity between 0 -
1000 NTU (for example, Hach model 2100P or an
approved similar instrument). The cable should not be less than 25m in
length. The meter should be calibrated
in order to establish the relationship between NTU units and the levels of
suspended solids. The turbidity
measurement should be carried out on a split water sample from the same water
sample collected for suspended solids analysis.
Sampling Equipment for Other Water Quality Parameters
A clean plastic water sampler
with capacity of at least 500 mL should be used to
take the water samples from the stream.
Water samples for SS, total reactive phosphorus and BOD5
measurement should be contained in high density polythene bottles. Water samples for oil and grease measurement
should be collected in glass bottles and preserved by addition of H2SO4. Water samples for ammonia nitrogen
measurement should be collected in high density polythene bottles and preserved
by addition of H2SO4.
All the samples should be packed in ice (cooled to 4°C without being
frozen) and delivered to the laboratory as soon as possible after
collection.
pH Measuring Equipment
A portable pH meter capable
of measuring a range between 0.0 and 14.0 should be provided to measure pH
under the specified conditions (e.g. Orion Model 250A or an approved similar
instrument).
Electromagnetic Flow Meter
A hand-held digital
electromagnetic flow meter (for example model Flo-mate 2000 or an approved
similar instrument) should be provided and used to measure water flow rate
during water quality monitoring. The
measurement should be conducted at fixed sampling points and water depth
throughout the monitoring programme.
Positioning Equipment
A hand-held digital Global
Positioning System (GPS) together with a suitably scaled map should be provided
and used during water quality monitoring.
Calibration of Equipment
All in-situ monitoring
instruments should be checked, calibrated and certified by a laboratory
accredited under HOKLAS or any other international accreditation scheme before
use, and subsequently re-calibrated at monthly intervals throughout all stages
of the water quality monitoring.
Responses of sensors and electrodes should be checked with certified
standard solutions before each use. Wet
bulb calibration for a DO meter should be carried out before measurement at
each monitoring station.
For the onsite calibration of
field equipment, the BS 1427:1998, “Guide to Field and on-site test methods for
the analysis of waters” should be followed.
Back-up Equipment
Sufficient stocks of spare
parts should be maintained for replacements when necessary. Back-up monitoring equipment should also be
available so that monitoring can proceed uninterrupted even when some equipment
is under maintenance, calibration, etc.
5.2.3
Measurement and Analysis
All laboratory works should
be carried out in a HOKLAS accredited laboratory. The determination work should start within 24
hours after the laboratory has collected the water samples. The results of SS laboratory measurements
should be provided to the client within 2 days of the sampling event (48
hours). The analyses should follow the
standard methods as described in APHA Standard Methods for the Examination of
Water and Wastewater, 19th Edition, unless otherwise specified (APHA 2540D for
SS).
The standard methods for the
in-situ and laboratory measurements that should be followed are shown in Table 5.2.

The submitted information should include pre-treatment procedures,
instrument use, Quality Assurance/Quality Control (QA/QC) details (such as
blank, spike recovery, number of duplicate samples per-batch etc), detection
limits and accuracy. The QA/QC details
should be in accordance with requirements of HOKLAS or another internationally
accredited scheme. It is recommended
that a minimum of 10% of the samples should be collected and analysed in duplicate for QA/QC purposes. Additional duplicate samples may also be
required by the EPD and WSD for inter-laboratory calibration. Remaining samples after analysis should be
kept by the laboratory for 3 months in case report analysis is required.
5.2.4
Monitoring Locations
Water quality monitoring locations are shown in Figure 5.1 and detailed in Table 5.3 below. A schedule for water quality monitoring
should be prepared by the ET/CS and approved by the EPD and WSD prior to the
commencement of the monitoring.

Note: An active agricultural land was recorded at the
downstream of Control Station (R1-U) and just upstream of the Development
Site. The Reference Station (R1-UM) is
used to monitor any influence of the farming activities on the water quality,
but not for the determination of Event and Action Plan. The Downstream (Gradient) Station (R1-D) is
used to monitor the dilution effect of water pollution and the further
potential influence to downstream sections of Sha Lo Tung Stream, but not for
the determination of Event and Action Plan.
|
The water depth in the stream may not be sufficient to take samples at
different depths and samples will only be taken at mid-depth.
Three replicates (3 samples) at each station from each independent
sampling event are required for all parameters to ensure a robust statistically
interpretable data set.
5.2.5
Monitoring Frequency
Baseline monitoring should be undertaken once every two days for at
least four weeks at the designated stations prior to the commencement of the
construction works. The baseline
monitoring should be scheduled to cover different time slot of a day. Baseline monitoring schedule prepared by the
ET/CS should be faxed to the PP, C, EPD and WSD 1 week prior to the
commencement of baseline monitoring.
Impact monitoring for the in-situ parameters and SS should be undertaken
3 days per week during the course of construction works whereas the monitoring
for other reference parameters (which are not typical parameters used for
construction runoff monitoring but reflect the general water quality
conditions) including oil and grease, ammonia nitrogen, total reactive phosphorus,
BOD5, COD and E. coli
which should be carried out on a monthly basis (refer to Table 5.1). For the
monitoring of the in-situ parameters and SS, the intervals between 2
consecutive sets of monitoring should not be less than 36 hours except where there
are exceedances of Action and/or Limit Level, in
which case monitoring frequency should be increased. The proposed water quality monitoring
schedule prepared by the ET/CS should be faxed to the PP, C, EPD and WSD on or
before the first day of the monitoring month.
The EPD and WSD should be notified immediately of any changes in
schedule by fax.
Post-project monitoring should be undertaken for 3 days at the
designated stations within a week after the completion of the construction
works. The intervals between 2
consecutive sets of monitoring should not be less than 36 hours. Post-project monitoring schedule prepared by
the ET/CS should be faxed to the PP, C, EPD and WSD one week prior to the
commencement of post-project monitoring.
5.2.6
Event and Action Plan
Water quality monitoring results at the Impact Station (R1-D) will be
evaluated against the Action and Limit levels shown in Table 5.4. The Action and
Limit Levels should be reviewed after the completion of the baseline monitoring
and would be amended, if appropriated.
The proposal for the amendment of the action and limit levels should be
submitted to EPD and WSD for agreement.

Operational
Phase
5.3.1
Monitoring
Parameters
Measurements
of the following parameters (considered to be relevant and potentially affected
due to the operational activities) should be undertaken by the Project
Proponent at strategic locations in Sha Lo Tung Stream (Figure 5.1). This ensures that any deteriorating water
quality arising from the operational activities will be readily detected and
timely action be taken to rectify the situation.
Parameters
to be measured in situ are:
• pH;
• water temperature
(°C);
• turbidity (NTU);
• dissolved oxygen (DO) (% saturation and mg
L-1); and
• salinity (0/00).
Parameters
to be measured in laboratory are:
• suspended solids
(SS) (mg L-1);
• oil and grease
(mg L-1);
• ammonia nitrogen
(mg L-1);
• total reactive
phosphorus (mg L-1);
• 5-day biochemical oxygen demand (BOD5)
(mg L-1);
• chemical oxygen
demand (COD) (mg L-1); and
• E.coli (cfu/100mL).
In
association with the water quality parameter measurements, relevant data should
be recorded, including the monitoring location, time, weather conditions, sampling water depth (m), water flow rate (m3/day) and
any special phenomena (provided with photographs if
appropriate) and
operational activities.
5.3.2
Monitoring
Equipment
The
requirements for the monitoring equipment used for operational monitoring are
the same as for the construction monitoring.
5.3.3
Measurement
and Analysis
All
laboratory work for laboratory measurements should be carried out in a HOKLAS
accredited laboratory. The determination
work should start within 24 hours after the laboratory has collected the water
samples. The results of laboratory
measurements should be provided to the client within 1 week of the sampling
event. The analyses should follow the
standard methods as described in APHA Standard Methods for the Examination of
Water and Wastewater, 19th Edition, unless otherwise specified.
The
standard methods for the in-situ and
laboratory measurements that should be followed are shown in Table 5.6.

The
submitted information should include pre-treatment procedures, instrument use, Quality
Assurance/Quality Control (QA/QC) details (such as blank, spike recovery,
number of duplicate samples per-batch etc), detection limits and accuracy. The QA/QC details should be in accordance
with requirements of HOKLAS or another internationally accredited scheme. It is recommended that a minimum of 10% of
the samples should be collected and analysed in duplicate for QA/QC
purposes. Additional duplicate samples
may also be required by EPD and WSD for inter-laboratory calibration. Remaining samples after analysis should be
kept by the laboratory for 3 months in case report analysis is required.
5.3.4
Monitoring
Locations
Water
quality monitoring locations are the same as those for the construction phase,
as shown in Figure
5.1 and detailed in Table 5.7 below. A schedule for water quality monitoring
should be prepared by the Project Proponent and approved by the EPD and WSD
prior to the commencement of the monitoring.

Note: An active agricultural land was recorded at the
downstream of Control Station (R1-U) and just upstream of the Development
Site. The Reference Station (R1-UM) is
used to monitoring any influence of the farming activities on the water
quality, but not for the determination of Event and Action Plan. The Downstream (Gradient) Station (R1-D) is
used to monitor the dilution effect of water pollution and the further
potential influence to downstream sections of Sha Lo Tung Stream, but not for
the determination of Event and Action Plan.
|
The
water depth in the stream may not be sufficient to take samples at different depths
and samples will only be taken at mid-depth.
Three
replicates (3 samples) at each station from
each independent sampling event are required for all parameters to ensure a
robust statistically interpretable data set.
5.3.5
Monitoring
Frequency
Monitoring
should be undertaken once per month during the first twelve months of the
operation phase. Two of the monitoring
events should be scheduled on the day just after the Ching Ming Festival Day
and Chung Yeung Festival Day. After the twelve-month monitoring, the
monitoring results will be reviewed by the Project Proponent to determine
whether it is necessary to extend the monitoring programme. The review results should be submitted to EPD
and WSD for agreement. The proposed
water quality monitoring schedule should be faxed to IEC, EPD and WSD before
the commencement of the monitoring. The
IEC, EPD and WSD should be notified immediately of any changes in schedule by
fax.
5.3.6
Event
and Action Plan
Water
quality monitoring results at the Impact Station (R1-D) will be evaluated
against the Action and Limit levels shown in Table 5.8. The Action and
Limit Levels should be reviewed after the completion of the baseline monitoring
and would be amended, if appropriated.
The proposal for the amendment of the action and limit levels should be
submitted to the IEC, EPD and WSD for agreement.

Any
noticeable change to water quality should be recorded in the data record sheets
and should be investigated and remedial actions should be undertaken to reduce
impacts. Particular attention should be
paid to the Operator’s implementation of the recommended mitigation measures.
Should
the monitoring results of the water quality parameters at any designated
monitoring stations indicate that the water quality criteria are exceeded, the
actions in accordance with the Event and Action Plan in Table 5.9 should be carried out.
In addition to monitoring,
regular environmental site audit is required to ensure the implementation of
surface runoff, drainage and sewage control measures detailed in Annex A.

Sewerage and Sewage Treatment IMPLIcations
6.1
Introduction
In accordance with the recommendations of the EIA, mitigation measures
have been proposed during the construction phase of the Project. Details of the mitigation measures are
presented in Annex A - Implementation
Schedule.
6.2
Construction
Phase
With adoption of Option 1 Sewage Disposal
Scheme as described in Section 7.6 of
the EIA Report, the following
mitigation measures are proposed:
·
Installation
of an approximately 2 km long 225 mm
diameter twin sewerage rising mains from the Development Site running along Sha Lo Tung Road to
the existing sewerage network at Ting
Kok Road;
·
Installation
of a stand-by pump (with a 100% standby
pumping capacity) in case of mal-function of the working pump; and
·
Construction
of a storage tank (fitted with a level
indicator and a high level alarm system, designed and constructed to comply
with the Buildings (Standards of Sanitary
Fitments, Plumbing, Drainage Works and Latrines) Regulations (Cap 123I)
reg. 47A) of minimum 180m3 capacity, to give approximately
three days withholding time over maximum visitor attendance over festival
periods to cater for the situation if the pumping facilities malfunctioned.
6.3
Operational Phase
The following measures are recommended to
manage the increase in sewage generation from the operation of the Project:
·
Provision
of adequate permanent water closets and urinals in the complex;
·
Emptying
of the sewage storage tank before and immediately after the festivals;
·
Provision
of portable toilets at the entrance of Sha Lo Tung road, next to Ting Kok Road
for contingency purpose; and
·
Should
the permanent sanitary facilities in the Development Site be closed due to
malfunction or emergency maintenance, additional portable toilets can be
arranged within a short period of time to cater the visitors, ie a total of 10 portable toilets can cater for a maximum
of 380 x 10 x 2 = 7,600 visitors if cleaning exercise is performed.

associated with the construction and operational phases, of the Project have been
identified in the EIA Report. In accordance with the recommendations of the
EIA, mitigation measures have been proposed during the construction and
operational phases of the Project.
Details of the mitigation measures are presented in Annex A - Implementation Schedule.
The works for the
establishment of the Ecological Reserve and the implementation of the
Conservation Management Plan are expected to enhance the conservation value of
Sha Lo Tung Valley. As a consequence,
the proposed Project is expected to bring about long term and sustainable
benefits to the ecology of Sha Lo Tung Valley and the habitats and associated
wildlife.
With the
implementation of good construction practice, no adverse
ecological impact is anticipated for these small scale works. Measures
relate to visitor control and general maintenance works have been recommended
during the operation / maintenance of Ecological
Reserve. Detailed ecological monitoring
on regular basis for the purpose of conservation management of the Ecological
Reserve will be undertaken in accordance with the recommendation of the
Conservation Management Plan.
To avoid ecological risk to
the Sha Lo Tung Valley (includes Sha Lo Tung SSSI and stream downstream, which
are considered to be of high ecological and conservation significance), any
discharge of construction runoff and wastewater from the Development Site Site and Sha Lo Tung Road
Improvement into these sites is prohibited.
The most effective way to check on ecological conditions is through
monitoring the stream habitat conditions, riparian vegetation, adult odonate and freshwater fish (through direct observation)
along Sha Lo Tung Stream. If the stream
habitats are being impacted by construction runoff and wastewater, there will
be some signs to be observed and immediate actions can be undertaken to rectify
the problem. Therefore stream, riparian
vegetation, adult odonate and freshwater fish
monitoring can obtain more useful information to audit the implementation and
effectiveness of the proposed mitigation measures than direct fauna sampling
and is less intrusive. The following
Section provides details of the ecological monitoring during construction and
operation to verify whether the potential exists for any impacts to occur to
Sha Lo Tung SSSI and stream.

Construction
Phase
8.2.1
Transplantation and
Compensatory Planting
Common Tutcheria
Tutcheria championii, Incense
Tree Aquilaria sinensis, Lamb of Tartary Cibotium barometz,
Hong Kong Pavetta Pavetta hongkongensis, Cycad Fern Brainea insignis, Rhodoleia Rhodoleia championii, Bamboo
Orchid Arundina graminifolia
and Willow-leaved Camellia Camellia salicifolia were identified as being of conservation
interest within the Development Site and along the Sha Lo Tung Road (for details refer to Section 9
Ecology of the EIA Report). As a mitigation measure, the affected
individuals (if confirmed as necessary during detailed engineering design) will
be transplanted prior to commencement of construction work to suitable nearby
habitats prior to the construction phase as far as practicable.
A detailed vegetation survey
will be conducted within the Development Site and along the Sha Lo Tung Road impacted
areas by a suitably qualified
botanist/ ecologist to identify and record the affected individuals of any
plant species of conservation interest (including, but not limited to, Common Tutcheria, Incense
Tree, Lamb of Tartary, Hong Kong Pavetta,
Cycad Fern, Rhodoleia and Willow-leaved Camellia) prior to
the commencement of site clearance works.
The survey
will also serve to identify any other plants of conservation interest which may
be present in the Development Site (eg Viburnum hanceanum)
which also need transplanting. Feasibility and suitability of transplanting the affected plant species
will be carefully studied and suitable receptor sites will be identified. A detailed transplantation proposal providing
information on transplantation methodology, recipient site, implementation programme, watering requirement, post-transplantation
monitoring and personnel involved shall be submitted to and approved by EPD, AFCD and District Lands
Office. Transplantation will be supervised by a
suitably qualified botanist/ horticulturist.
After transplantation, monitoring will be undertaken to check the
performance and health conditions of the transplanted individuals on a weekly
basis for the first month after transplantation and on a monthly basis for an
additional eleven months. Remedial
actions will be discussed with EPD, AFCD and District Lands Office in the event of unsuccessful transplantation.
The EIA Report has recommended provision
of approximately 2 ha of on-site compensatory tree and shrub planting for the loss of secondary woodland
(approximately 0.03 ha due to the Development Site and approximately 0.2 ha due
to the Sha Lo Tung Road Improvement) and plantation (approximately 0.43 ha due
to the Sha Lo Tung Road Improvement). The compensatory planting will be planted
on-site, either within the Development Site or the Ecological Reserve. The
concept of the proposed compensatory planting at the Development Site is
presented in Figures
9.1-9.3. The proposed
planting areas within the Ecological Reserve is recommended in grassland shrubland mosaic to the north of the Study Area and
presented in Figure 9.2. The
location and size of the compensatory planting should be approved by the EPD
and AFCD. The selection of planting
species shall be made with reference to the species identified in Annex
F2 and be native to Hong Kong or the South China
region. The arrangement of the
on-site compensatory planting, ie tree/ shrub mix and
exact location, will be subject to the detailed landscape design. The cut
slopes along the improved Sha Lo
Tung Road (with approximately 0.47 ha in total)
will also be planted with native shrubs and trees or hydroseeded
subject to the gradients. After
compensatory tree and shrub planting, twelve months monitoring will be undertaken
to check the performance and health condition of the planted tree and shrub
individuals on a monthly basis. Remedial
actions will be discussed with AFCD in the event of unsuccessful planting.
8.2.2
Stream Monitoring
Stream
monitoring should be undertaken by a qualified person along the Sha Lo Tung
Stream next to the Development Site (the stream monitoring section) as shown in
Figure
5.1 daily for working days during the
construction phase. No more than three
weeks prior to the commencement of the construction phase and the impact
monitoring, baseline stream monitoring will be undertaken on three occasions
(days) within a week. Within a week
after the completion of the construction works, a post-project stream
monitoring will be carried out on three occasions (days).
The
qualified person (Environmentalist/ Ecologist with at least 3 years relevant
experience in field surveys) should walk along the stream bank of the stream monitoring
section as far as is possible, to identify the signs of the impact. Stream photographic records at five fixed
locations along the stream should be established during baseline, impact and
post-project monitoring. The stream
photographic records should be reviewed and compared; during the construction
phase monitoring, this will enable identification of any daily changes of the
stream condition. Should any signs of
the impact observed during the stream monitoring be confirmed or suspected to
be related to the construction work activities, the construction works should
be halted immediately until the pollution source(s) can be identified. A Preliminary Daily Stream Monitoring
Checklist is presented in Annex C.
The major potential water quality impact
and signs of abiotic impacts associated with specific
construction activities are summarised in Table
8.1.

silt/ sediment covering the stream bed (particularly the rocky bottom);
rubbish observed along the stream banks and in the stream
|
|
Spillages of liquid stored on-site, such as oil, diesel and solvents
|
Decrease stream water DO level and pollution of the stream

|
Bad smelling and turbid water
|
The
signs of the abiotic impacts and the pollution
source(s) are easily identified by an Environmental Specialist/ Ecologist who
is experienced in field surveys. Inspection
of the stream conditions is therefore recommended as a sensitive, non-intrusive
and effective monitoring method. Should
any signs of the impact be observed during the stream monitoring, the actions
listed in the Event and Action Plan in Table
8.2 should be carried out.
Baseline
stream hydrology monitoring, including stream water level, stream wet width and
flow rate, should be conducted at least 5 days in wet season
and 5 days in dry season
at Stations R1-U, R1-M and R1-D (Figure 5.1)
prior to the commencement of any construction works. Impact stream hydrology monitoring should be
conducted quarterly (5 monitoring days per quarter) during construction
phase. A permanent marker is recommended
to install at the four stations (prefer to install at the middle stream pool)
so as to monitor the stream water level and wet width more accurate and
effectively. The baseline and impact
monitoring days are preferred to be conducted in different weather conditions (ie rainy day, sunny day or after long period of sunny/rainy
days). Should adverse impact (ie reduction in the stream flow) be identified during the
stream hydrology monitoring, the actions listed in the Event and Action Plan in
Table 8.2 should be carried out.
8.2.3
Biological Monitoring
The species composition and relative
abundance of riparian vegetation, adult odonate and
fish communities along Sha Lo Tung perennial stream, (particularly in the
proximity to the development site) and the wet abandoned agricultural land are
considered as the key biological indicators of the aquatic habitat
conditions. Any water pollution due to
uncontrolled surface runoff from the proposed development would influence the
water quality of Sha Lo Tung perennial streams and / or pools within the wet
abandoned agricultural land at the northeast of the Development Site, and
therefore also the associated floral and faunal communities.
A baseline biological monitoring for the
riparian vegetation, adult odonate and fish
communities should be conducted once during the wet season (at least 5 days)
and once during the dry season (at least 5 days) along the Sha Lo Tung stream
and the pools located in the wet abandoned agricultural land (exact location
refer to Figure 5.1) prior to the commencement of any
construction works. The monitoring
should also be undertaken at the upstream and down stream of the Impact Stream
Monitoring Section. Upstream of the
Impact Stream Monitoring Section is considered as the control station and the
down stream of the Impact Stream Monitoring Section is considered as the
gradient station.
The species diversity, relative abundance
and community structure of the riparian vegetation, adult odonate
and fish in the pools located in the wet abandoned agricultural land and along
the control, impact and gradient stream sections, should be recorded during the
monitoring. Riparian vegetation, either
side of the pools, the control, impact and gradient Stream Sections as well as
the aquatic plants beside the pools and along the stream sections, encountered
and their relative abundance will be recorded with special attention to the
signs of pollution, ie mud, observed on the leave
surface. Adult odonate
(with particular focus on stream specialists) will be surveyed using the
transect count method along the stream (Figure
5.1). Any adult odonate within 10 m from either
side of the survey transect (stream monitoring section as shown in Figure
5.1)
will be identified and counted. The fish
(with particular focus on Hong Kong Paradise Fish, Small Snakehead and
Predaceous Chub) will be surveyed by direct observation and active searching if
necessary. The fish encountered and
their relative abundance will be recorded along the stream monitoring
sections. The biological monitoring
shall be conducted by experienced ecologist(s) of more than 3 years experience
on riparian vegetation, adult odonate and fish
communities. More updated methodology, monitoring frequency, action and limit levels,
and personnel involved shall be submitted to and approved by EPD and AFCD prior
the commencement of the baseline monitoring.
The impact biological monitoring for the
riparian vegetation, adult odonate and fish
communities should be conducted biweekly throughout the construction
period. Baseline and impact monitoring
data, in particular the species composition, diversity and relative abundance,
should be compared, any substantial differences in habitat characteristics
(e.g. water quality, riparian and aquatic vegetation), difference between the
pool and along the control, gradient and impact stream sections and the
seasonality of the fauna should be noted.
8.2.4
Event and Action Plan
Ecological monitoring results at the pools
located in the wet abandoned agricultural land at the northeast of the
Development Site and the Impact Stream Monitoring Section will be evaluated
against the Action and Limit levels shown in Table 8.2. The Action and
Limit Levels should be reviewed after the completion of the baseline monitoring
and would be amended, if appropriated.
The proposal for the amendment of the action and limit levels should be
submitted to the EPD and AFCD for agreement.

Any
noticeable change to stream water quality and biological parameters should be
recorded in the data record sheets and should be investigated and remedial
actions should be undertaken to reduce impacts.
Particular attention should be paid to the Contractor’s implementation
of the recommended mitigation measures.
Should
the monitoring results of the stream water quality, stream hydrology and
biological parameters at the Impact Stream Monitoring Section and/ or
pools located in the wet abandoned agricultural land at the northeast of the
Development Site indicate
that the stream water quality, stream hydrology and biological criteria are
exceeded, the actions in accordance with the Event and Action Plan in Table 8.3 should be carried out.

Landscape and Visual Impact
9.1
Introduction
The EIA Report has recommended that EM&A for landscape
and visual resources is undertaken during both construction and initial
operational phases (post –construction) of the project. The implementation and maintenance of
landscape mitigation measures (Annex A) should be checked
to ensure 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
Design
Phase
The following measures are recommended to mitigate the
landscape and visual impacts:
·
DM1- Design of Structures. The structures shown in the photomontages are
to illustrate the mass of the structures only.
During the design phase of the development, architectural features such
as the eaves, cladding materials and finishes etc. will be detailed. All of these elements will greatly improve
the appearance of the structures. Built
structures will utilise appropriate designs to complement the surrounding
landscape, including a stepped form that respects the site contours;
·
DM2- Colours. Colours for the structures can be used to
complement the surrounding area. Lighter
colours such as shades of light grey, off-white and light brown may be utilised
to reduce the visibility of the structures; and
·
DM3-Green Roofs. Green roofs and vertical greening shall be
designed and constructed to integrate the new buildings into the surrounding
environment.
9.3
Construction
and Initial Operational Phases
A specialist Landscape Sub-Contractor should be
employed by the Contractor for the construction of landscape works and
subsequent maintenance operations during a 24-month establishment period. A Registered Landscape Architect should be
employed as a member of the ET to supervise the specialist Landscape
Sub-contractor for the implementation of landscape works, both
hard and soft, involved.
Measures undertaken by both the Contractor(s) and the
specialist Landscape Sub-Contractor during the construction phase and first
year post-construction will be audited by the Registered Landscape Architect of
the ET, to ensure compliance with the intended aims of the measures. Site inspections should be undertaken at
least once every two weeks throughout the landscaping plants establishment
period when planting works are being undertaken.
A tree survey update should be prepared, for DLO
submission, and for the purpose of existing trees protection. Removal of existing trees should be minimised.
Post-construction phase auditing will be restricted to
the 24-month establishment works of the landscaping proposals and thus only the
items in the list below related to this period are relevant to the
post-construction (initial operational phase) audit; the remainder is for the
construction phase site inspections. The
broad scope of the audit/inspections is detailed below but should also be
undertaken with reference to the more specific checklist provided in Table 9.1.
·
the extent of the agreed works areas should
be regularly checked during the construction phase. Any trespass by the Contractor(s) outside the
limit of the works, including any damage to existing trees will be noted;
·
the progress of the engineering works should be regularly reviewed
on site to identify the earliest practical opportunities for the landscape
works to be undertaken;
·
existing trees and vegetation within the study area which are not
directly affected by the works are retained and protected to the extent safely
practical;
·
the methods of protecting existing vegetation proposed by the
Contractor(s) are acceptable and enforced;
·
preparation, lifting transport and re-planting operations for any
transplanted trees;
·
landscaping works are carried out in accordance with the
specifications;
·
the planting of new trees, shrubs, groundcover, climbers, ferns,
grasses and other plants, together with the replanting of any transplanted
trees are carried out properly and within the right season; and
·
necessary horticultural operations and replacement
planting are undertaken throughout the Establishment Period to ensure the
healthy establishment and growth of both transplanted trees and newly
established plants.
Table 9.1 Construction/Post-Construction Phase Audit Checklist

Measures
|
|
CM1
|
Car Park Tree Planting. Advanced trees are to be planted to provide
shade to the car park areas and to reduce the mass of the paved areas.
|
|
CM2
|
Retention of Existing Trees. Existing trees without conflict with the
building structures will be retained to reduce impacts on the site.
|
|
CM3
|
Compensatory Planting. Where vegetation must be removed, the
felled trees within the Development Site and along Sha Lo Tung Road will be compensated
with new planting tree numbers at a ratio of 3:1.
|
|
CM4
|
Columbarium Courtyard
Plantings. The internal courtyards and
areas surrounding the new development will be landscaped to integrate the
buildings into the landscape.
|
|
CM5
|
Open Grassland and Lawn Areas. Areas of open grassland/lawns will be
created to provide areas for passive recreation and to complement the surrounding
grassland areas.
|
|
CM6
|
Buffer Planting. Trees and shrubs will be planted around
much of the site boundaries to screen the development and help integrate the
development into the surrounding landscape.
|
|
CM7
|
Stream Creation. Streams containing pools and riffles will
be created to create a natural and harmonious landscape within the
development. It must be noted that
these features will not be connected in any way to the natural stream
bordering the site.
|
|
CM8
|
Early Planting Works. New plantings are to be installed in
available and formed lands during the construction works to reduce landscape
impacts.
|
|
CM9
|
Transplantation of Plants. In addition, plant materials that are in conflict with the development, that are in
suitably good condition and of ecological value will also be transplanted.
|
|
CM10
|
Soil
Stabilisation and Embankment Planting. During the design process a soil
stabilisation and embankment planting strategy should ensure that land
affected by slope excavation can be replanted. Soil preparation and the selection and
provision of suitable growing medium is to be completed in accordance with
the relevant best practice guidelines
|
|
CM11
|
Cut
Stabilisation Areas of cut to be stabilized for operational requirements. Materials and finishes of stabilization to
be selected to complement the surrounding landscape. All landscape stabilisation measures must
conform to GEO 1/2000 – Technical Guidelines on
Landscape Treatment and Bio-engineering of Man-made Slopes and Retaining
Walls.
|
|
CM12
|
Colour of
Site Hoardings. In order to mitigate
the visual impact of these temporary hoardings, it is recommended that the
hoardings be erected at a uniform height, with a uniform colour that complements
the existing landscape.
|
The landscape mitigation measures are shown in Figures 9.1-9.4. Additional
good site practices are also recommended to mitigate the impacts:
·
Cultivation of areas impacted during
construction - Areas impacted
during the construction phase that are not required during the operation phase,
are to be cultivated to a depth of 300mm in accordance with accepted Hong Kong practice and guidelines. The cultivation shall
involve ripping of compacted soil by mechanical means. Great care must be taken to avoid any run-off
into the existing streams. Therefore this mitigation measure is not to be
adopted in areas sloping towards any existing watercourses.
·
Quality control of imported materials - Appropriate quality control measures
are to be used to ensure that all imported materials including but not limited
to soils, mulches, plants etc. are to be free of pests and contaminants that
may adversely affect the surrounding environment. All landscape construction works are to be
supervised by suitably trained professionals.
In the event of non-compliance with the
recommendations of the EIA Report, the EM&A Manual and the Landscape Plan,
the responsibilities of the relevant parties is detailed in the Event /Action
plan provided in Table 9.2.

Introduction
In accordance
with the recommendations of the EIA, mitigation measures have been proposed
during the construction phase of the Project.
Details of the mitigation measures are presented in Annex A
- Implementation Schedule.
10.2
Construction
Phase
During the construction stage of the southern section
of the Sha Lo Tung Road Improvement, an archaeological
monitoring covering the area as shown in Figure 10.1 is recommended
to preserve potentially impacted archaeological resources by record. The monitoring should be conducted by a
professional archaeologist, who should obtain a Licence to Excavate and Search for Antiquities under the Antiquities
and Monuments Ordinance and be engaged by the
project proponent or environmental team. The need and scope of archaeological
monitoring is subject to the detailed design of construction works.
If laying of drainage pipes
is required adjacent to an earth shrine located at the southern section of Sha
Lo Tung Road (LF01) and sheet piling works cannot be avoided, a construction
vibration monitoring is recommended to be conducted by the construction
contractor during the construction work adjacent to LF01. The monitoring should include:
·
A pre-condition survey for LF01 conducted by a structural engineer
to record the state of the feature (including all cracks) before construction
work commences;
·
Trial test of vibration generated from ground borne vibration
related works;
·
Evaluation and review of the construction method to avoid and
minimise the potential impact; and
·
Recommendation for vibration monitoring and protection
measures. This would include the
establishment of a vibration limit, monitoring frequency and protective measures
to be agreed with the Engineer and AMO.
In addition, during the construction stage of the Sha
Lo Tung Road Improvement adjacent to LF01, the construction contractor should
ensure visitors’ safe access to the shrine.
A temporary fence with access entrance should be erected to prevent any
direct impact to LF01 during the construction work.
10.3
Operational
Phase
No EM&A programme is
required.
11
Site environmental Audit
11.1
Site
Inspection
Site
inspections provide a direct means to track and ensure the
enforcement of specified environmental protection and pollution control
measures. The inspections should be
undertaken on a daily basis by the CS, and weekly basis by ET/CS, Contractor
and the IEC during the construction and operational phases to ensure that
appropriate environmental protection and pollution control mitigation measures
are properly implemented, in particular the temporary
drainage system and runoff control measures. The
CS will have the authority to stop the construction works should the
implementation and effectiveness of the proposed mitigation measures cannot be
satisfied. Additionally, the ET will be responsible
for defining the scope of the inspections, detailing any deficiencies that are
identified, and reporting any necessary action or mitigation measures that were
implemented as a result of the inspection; the results of the inspections
should be made available to the Contractor, IEC, AFCD and EPD.
The areas of inspection should include the general environmental
conditions in the vicinity of the Site and pollution control and mitigation
measures within the Site; it should also review the environmental conditions
outside the site area which are likely to be affected, directly or indirectly,
by site activities. The CS/ ET should
make reference to the following information in conducting the inspections:
·
the EIA and EM&A recommendations on environmental protection
and pollution control mitigation measures;
·
ongoing results of the EM&A programme;
·
works progress and programme;
·
individual works method statements which will include proposals on
associated pollution control measures;
·
contract specifications on environmental protection; and
·
relevant environmental protection and pollution
control laws.
The CS/ET’s inspection findings and their
associated recommendations on improvements to the environmental protection and
pollution control works should be submitted to the IEC, EPD, AFCD and the
Contractor within 24 hours, for comment and for taking immediate action. They should also be presented, along with the
remedial actions taken, in the monthly EM&A reports. The Contractor should follow the procedures
and time-frames stipulated in the environmental site inspection for the
implementation of mitigation proposals.
An action reporting system should be formulated and implemented to
report on any remedial measures implemented subsequent to the site inspections.
Ad hoc site inspections should also
be carried out by the CS/ET and IEC if significant environmental problems are
identified. Inspections may also be
required subsequent to receipt of an environmental complaint, or as part of the
associated investigation work.
11.2
Compliance with Legal and Contractual
Requirements
There will be contractual environmental
protection and pollution control requirements as well as Hong
Kong’s environmental protection and pollution control laws which
the construction activities will comply with.
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, AFCD and EPD 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, AFCD, 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, AFCD and EPD 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.
11.3
Environmental
Complaints
The complaints handling
procedure should be as follows:
The ET Leader should undertake
the following procedures upon receipt of a complaint:
·
log complaint and date of receipt into the complaint database and
inform the Contractor, PP, EPD and IEC immediately;
·
investigate the complaint jointly with the Contractor and the IEC
and discuss with the Contractor and IEC to determine its validity and to assess
whether the source of the issue is due to construction activities;
·
if a complaint is considered valid due to
the construction activities, the ET Leader should identify mitigation measures
in consultation with the Contractor, and submitted to the IEC and EPD for
review. If mitigation measures are
required, the ET Leader should advise the Contractor accordingly;
·
review the Contractor's response on the identified mitigation
measures and the updated situation;
·
if the complaint is transferred from EPD, an interim report should
be submitted to EPD on the status of the complaint investigation and follow-up
action within the time frame assigned by EPD;
·
undertake additional monitoring and audit to verify the situation
if necessary and ensure that any valid reason for complaint does not recur;
·
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 should be reported within the time frame assigned by EPD;
and
·
record the complaint, investigation, the
subsequent actions and the results in the monthly EM&A reports.
During the complaint
investigation work, the ET Leader and Contractor should cooperate with the IEC
and EPD in providing the 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.
11.4
Log-Book
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
assessment. The ET Leader should notify
the IEC and EPD 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, EPD, WSD, ACE EIA Subcommittee and Contractor)
assisting in supervision of the implementation of the recommendations of the EIA Report or his authorised officers.
12
