1.1.1
The engineering feasibility study of the Anderson Road Quarry (ARQ)
Development in East Kowloon has been conducted under the Agreement No. CE18/2012
(CE) “Development of Anderson Road Quarry - Investigation” (the FS) to
ascertain the feasibility of implementing the development proposal. The FS was classified as a designated project
under the Schedule 3 of the Environmental Impact Assessment Ordinance (EIAO).
Hence, as a part of the study, an environmental impact assessment (EIA) report
titled “Development of Anderson Road Quarry“ has been submitted and approved
under the EIAO (Register: AEIAR-183/2014) on 28 July
2014.
1.1.2
Community engagement was conducted under the FS and public views were
collected. There was no strong view from the public on the cavern development
and some of the LegCo members recommended promoting
business opportunity or educational purposes in making use of the cavern. It
was recommended in the FS to construct and operate cavern development within
the boundary of the ARQ Development.
1.1.3
Subsequently, a Project Profile No. PP-501/2014 was submitted for the EIA
study brief under section 5(1)(a) of the EIAO. An EIA
Study Brief No. ESB 269/2014 “Development of Anderson Road Quarry Site – Rock
Cavern Developments” was issued to Civil Engineering and Development Department
for carrying the environmental impact assessment for the Project presented in
this EIA Report on 10 March 2014.
1.1.4
This Project comprises the construction of a cavern located on the rock slopes in the northeast
side of the ARQ Development.

2.1.1
In accordance with the EIA Report, with the proposed dust suppression measures in place, no adverse air quality impact is expected during the construction phase
of the Project. The impact from the Project itself
contributed to the cumulative air quality impact is minimal, therefore, environmental
monitoring for construction phase of the Project is considered
unnecessary. However, regular inspections of the construction activities and works
areas should be conducted during the construction phase to ensure proper
implementation of the recommended mitigation measures.
2.2
Audit Requirement
2.2.1
The ET shall conduct site audit to inspect the construction activities and works sites at least on a weekly basis
to ensure the mitigation measures to be properly implemented.
2.2.2
Site audits should be based on the mitigation measures for the air
pollution control as recommended in EIA Report.
In the event that the recommended mitigation measures are not fully or
properly implemented, the ET should report the deficiency to the Engineer and
the Contractor. The Contractor shall
implement the remedial and corrective action immediately. The ET shall re-inspect the site conditions
upon the completion of the remedial and correction action.
2.3.1
Mitigation measures for dust control have been recommended in the EIA
Report. The Contractor shall be
responsible for the design and implementation of these measures. Recommended mitigation measures
to minimise the adverse impacts on air quality during construction phases are
detailed in Section 2.3.2 below.
2.3.2
To ensure compliance with the guideline level and AQO at the ASRs, the
Air Pollution Control (Construction Dust) Regulation should be implemented and
good site practices should be incorporated in the contract clauses to minimize
construction dust impact. A number of below dust suppression measures are
proposed to be implemented.
Ÿ Watering once per hour on
active construction work areas, and the watering
application intensity is estimated to be 0.152 L/m2 so as to achieve
a dust removal efficiency of 87.5%;
Ÿ Any excavated or stockpile of
dusty material should be covered entirely by impervious sheeting or sprayed
with water to maintain the entire surface wet and then removed or backfilled or
reinstated where practicable within 24 hours of the excavation or unloading;
Ÿ Any dusty material remaining
after a stockpile is removed should be wetted with water and cleared from the
surface of roads;
Ÿ A stockpile of dusty material
should not extend beyond the pedestrian barriers, fencing or traffic cones;
Ÿ The load of dusty materials
on a vehicles leaving a construction site should be covered entirely by
impervious sheeting to ensure that the dusty materials do not leak form the
vehicle;
Ÿ Where practicable, vehicles
washing facilities including a high pressure water jet should be provided at
every discernible or designated vehicle exit point. The area where vehicle
washing takes place and the road section between the washing facilities and the
exit point should be paved with concrete, bituminous materials or hardcores;
Ÿ When there are open
excavation and reinstatement works, hoarding of not less than 2.4m high should
be provided as far as practicable along the site boundary with provision for
public crossing. Good site practice shall also be adopted by the Contractor to
ensure the conditions of the hoardings are properly maintained throughout the
construction period;
Ÿ The portion of any road
leading only to construction site that is within 30m of a vehicle entrance or
exit should be kept clear of dusty materials;
Ÿ Surfaces where any pneumatic
or power-driven drilling, cutting, polishing or other mechanical breaking
operation takes place should be sprayed with water or a dust suppression
chemical continuously;
Ÿ Any area that involves
demolition activities should be sprayed with water or a dust suppression
chemical immediately prior to, during and immediately after the activities so
as to maintain the entire surface wet;
Ÿ Where a scaffolding is
erected around the perimeter of a building under construction, effective dust
screens, sheeting or netting should be provided to enclose the scaffolding from
the ground floor level of the building, or a canopy should be provided from the
first floor level up to the highest level of the scaffolding;
Ÿ Any skip hoist for material
transport should be totally enclosed by impervious sheeting;
Ÿ Every stock of more than 20
bags of cement or dry pulverised fuel ash (PFA) should be covered entirely by
impervious sheeting or placed in an area sheltered on the top and the three
sides;
Ÿ Cement or dry PFA delivered
in bulk should be stored in a closed silo fitted with an audible high level
alarm which is interlocked with the material filling line and no overfilling is
allowed; and
Ÿ Exposed earth should be
properly treated by compaction, turfing, hydroseeding, vegetation planting or sealing with latex,
vinyl, bitumen, shortcrete or other suitable surface
stabiliser within six months after the last construction activity on the
construction site or part of the construction site where the exposed earth
lies.
2.3.3
The implementation schedule for the recommended air quality mitigation
measures is presented in Appendix B.

Noise Impact
3.1.1
The EIA has considered the potential noise impacts associated with the
construction and operational phases of the Project. This section summarises
EM&A requirement on noise.
3.2.1
The EIA Report has predicted no adverse construction noise impacts from
the Project, and therefore construction phase noise monitoring is not necessary
under the EM&A programme. Nevertheless, regular site inspection during
construction phase is recommended to ensure the
effectiveness of implementation of proposed mitigation measures presented in
the implementation schedule in Appendix B.
3.3.1
The maximum permissible sound power levels for the fixed noise sources
of the cavern, i.e. the ventilation shaft(s), were determined in the EIA
Report. To ensure that the noise generated from the fixed plant
operations would comply with the noise standards stipulated in the EIAO-TM, the
specified sound power levels should be strictly observed by the Project
Proponent and/or Contractor and the recommended mitigation measures in Appendix B should be
implemented. To ensure compliance
with the fixed plant noise criteria, a commissioning test for the fixed
plant of the ventilation shaft(s) should be conducted.
3.4.1
The recommended mitigation measures for noise impacts are presented the
implementation schedule in Appendix B.
3.4.2
In the event of complaints, or non-compliance being observed, the ET
and the Contractor should review the effectiveness of these mitigation
measures, design alternative or additional mitigation measures as appropriate
and propose to ER for approval, and implement these alternative or additional
measures.
4.1.1
As recommended in the EIA Report, inland water quality monitoring
should be carried out during the site clearance and slope excavation works of
the Project to ensure that any unacceptable increase in suspended solids /
turbidity and decrease in dissolved oxygen in the nearby inland waters due to
the construction activities could be readily detected and timely action be
taken to rectify the situation. It is
also recommended that regular site inspections during the entire construction
phase should be undertaken to inspect the construction activities and works
areas in order to ensure the recommended mitigation measures are properly
implemented.
4.1.2
Adverse water quality impacts associated with the operation of the
Project are not expected. Thus, no water
quality monitoring and audit programme is required during the Project
operation.
4.1.3
This section describes the requirement of water quality monitoring
during site clearance and slope excavation works of the Project.
4.2.2 The
levels of DO, turbidity and pH should be measured in situ whereas SS should be determined by laboratory analysis.
4.3.1
One water quality monitoring station, namely Station G, is proposed in
the upstream tributary of Tseng Lan Shue Stream near the Project works as listed in Table
4.1 and also shown in Figure 4.1. As the whole Tseng Lan Shue Main Stream and all its
tributaries are located at the downstream of the Project works, no upstream
control monitoring station can be defined for this Project. The selected monitoring station is
considered the most practical station for water sampling in terms of its
accessibility and water depth. The water
courses further upstream (or closer to the Project site) are only small open
ditches mainly collecting rainwater from the hill side, which are either
difficult to be accessed or have very low flow.
4.3.2
Sampling should be taken at the water surface of Station G. The monitoring station should not be influenced by any local
pollution source so that representative data could be sampled. The ET Leader shall further review the status and suitability of the
water quality monitoring station prior to the commencement of the monitoring
works, and where necessary, propose with justification for changes to monitoring
location or other requirements of the EM&A programme, and seek approval
from the IEC and EPD.

4.4.1
Baseline conditions at the designated monitoring station should be
established and agreed with EPD prior to the commencement of construction
works. The purpose of the baseline monitoring is to establish ambient
conditions prior to the commencement of the works and to demonstrate the
suitability of the proposed monitoring station. The baseline conditions
should normally be established by measuring the water quality parameters
including DO, turbidity, SS and pH as specified in Section 4.2.
4.4.2
The baseline monitoring should be taken at the designated monitoring
station, three days per week, for at least 4 weeks prior to the commencement of
construction works. Temporal and spatial variations should be taken into
account. There should not be any construction activities in the vicinity of the
station during the baseline monitoring. The interval between 2 sets of
monitoring should not be less than 36 hours. Replicate in-situ measures should be carried out in each sampling event.
4.4.3
Baseline monitoring schedule should be submitted to EPD at least 4
weeks prior to the commencement of baseline monitoring. EPD should also be notified immediately for
any changes in schedule.
4.4.4
The baseline monitoring report should be submitted to EPD at least 4
weeks before the commencement of the construction works for agreement. The baseline monitoring report should be
certified by the IEC before submission to EPD.
4.5.1
During the site clearance and slope excavation works of the Project,
impact monitoring should be undertaken three days per week with sampling /
measurement at the designated monitoring station. Upon completion of the
site clearance and slope excavation works, the monitoring exercise at the
designated monitoring location should be continued for four weeks in the same
manner as the impact monitoring. The
interval between two sets of monitoring should not be less than 36 hours except
where there are exceedances of Action and/or Limit Levels, in which case the
monitoring frequency will be increased.
4.5.2
Replicate in-situ
measurements should be carried out in each sampling event. The monitoring probes should be retrieved out
of water after the first measurement and then redeployed for the second
measurement. Where the difference in
value between the first and second readings of DO, turbidity or pH is more than
25% of the value of the first reading, the reading should be discarded and
further readings should be taken.
4.5.3
The water quality monitoring schedule should be submitted to EPD at
least 1 week before the first day of the monitoring month. EPD should be
notified immediately of any changes in schedule. If the monitoring data collected at the
designated station indicate that the Action or Limit Levels as shown in Table
4.3 are exceeded, appropriate actions should be taken in accordance with
the Event and Action Plan in Table 4.4.
4.6.1
Implementation of regular site audits aim to ensure that the
recommended mitigation measures are properly undertaken during proposed
construction works. It can also provide
an effective control of any malpractices and therefore achieve continual
improvement of environmental performance on site.
4.6.2
Site audits shall be carried out by the ET and shall be based on the
mitigation measures for water pollution control recommended in the
implementation schedule as presented in Appendix B. In the event that the recommended mitigation
measures are not fully or properly implemented, deficiency shall be recorded
and reported to the site management.
Suitable actions are to be carried out to:
Ÿ investigate the problems and the causes;
Ÿ issue action notes to the Contractor who is responsible for the works;
Ÿ implement remedial and corrective actions immediately;
Ÿ re-inspect the site conditions upon completion of the remedial and corrective
actions; and
Ÿ record the event and discuss with the Contractor for preventive actions.
4.7.1
Other relevant data should also be recorded, such as: monitoring
location / position, time, water depth, weather conditions and any special
phenomena underway near the monitoring station.
A sample data record sheet is shown in Appendix C for reference.
Dissolved
Oxygen and Temperature Measuring Equipment
4.8.1
The instrument should be a portable and weatherproof DO measuring
instrument complete with cable and sensor, and use a DC power source. The
equipment should be capable of measuring:
Ÿ a DO
level in the range of 0 ‑ 20 mg/L and 0 ‑ 200% saturation; and
Ÿ a temperature of 0 ‑ 45 degree Celsius.
Turbidity
Measurement Instrument
4.8.2
The instrument should be a portable and weatherproof
turbidity-measuring instrument using a DC power source. It should have a
photoelectric sensor capable of measuring turbidity between 0 - 1000 NTU (for
example, Hach model 2100P or an approved similar
instrument).
pH Measurement Instrument
4.8.3
The instrument should consist of a potentiometer, a glass electrode, a
reference electrode and a temperature-compensating device. It should be
readable to 0.1pH in a range of 0 to 14. Standard buffer solutions of at
least pH 7 and pH 10 should be used for calibration of the instrument before
and after use.
Sampler
4.8.4
A water sampler is required. It should comprise a transparent PVC
cylinder, with a capacity of not less than 2 litres, which can be effectively
sealed with latex cups at both ends. The sampler should 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 (for example, Kahlsico Water Sampler or an approved similar instrument).
Sample
Containers and Storage
4.8.5 Water samples for SS should
be stored in high density polythene bottles with no preservative added, packed
in ice (cooled to 4°C without being frozen) and delivered to the laboratory and
analysed as soon as possible after collection. Sufficient volume of
samples should be collected to achieve the detection limit stated in Table
4.2.
Calibration
of In-Situ Instruments
4.8.6
The DO meter and turbidimeter should be
checked and calibrated before use. DO meter and turbidimeter
should be certified by a laboratory accredited under HOKLAS or any other
international accreditation scheme, and subsequently re-calibrated at three
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 location.
4.8.7
Sufficient stocks of spare parts should be maintained for replacements
when necessary. Backup monitoring equipment should also be made available
so that monitoring can proceed uninterrupted even when some equipment is under
maintenance, calibration, etc.
4.9.1
Analysis of SS should be carried out in a HOKLAS or other international
accredited laboratory. Sufficient water samples should be collected at
the monitoring station for carrying out the laboratory determinations. The
determination work should start within 24 hours after collection of the water
samples. The analyses should follow the American Public Health
Association (APHA) Standard Methods for the Examination of Water and Wastewater
or an equivalent method subject to the approval of EPD. Analytical
methods and detection limits for SS are present in Table 4.2.

4.9.2
The testing of SS should be HOKLAS accredited (or if not, approved by
EPD) and comprehensive quality assurance and control procedures in place in
order to ensure quality and consistency in results.
4.9.3
Detailed testing methods, pre-treatment procedures, instruments use,
Quality Assurance / Quality Control (QA/QC) details (such as blank, spike
recovery, number of replicate samples per batch, etc.), detection limit and
accuracy shall be submitted to EPD for approval prior to the commencement of
monitoring programme. EPD may also
request the laboratory to carry out analysis of known standards provided by EPD
for quality assurance. The QA/QC shall
be in accordance with the requirements of HOKLAS or international accredited
scheme. The QA/QC results shall be
reported. The testing methods and
related proposal should be checked and certified by IEC before submission to
EPD for approval.
4.9.4
Additional replicate samples may be required by EPD for
inter-laboratory calibration. Remaining samples after analysis should be
kept by the laboratory for 3 months in case repeat analysis is required.
If in-house or non-standard methods are proposed, details of the method
verification may also be required to submit to EPD. In any circumstance,
the sample testing should have comprehensive quality assurance and quality
control programmes. The laboratory should prepare to demonstrate the
programme to DEP or his representatives when requested.
4.10
Event and Action Plan
4.10.1
The water quality criteria, namely action and limit levels, are shown
in Table 4.3. These criteria
should be applied to ensure that any deterioration of water quality is readily
detected and timely action is taken to rectify the situation. Should the
monitoring results of the water quality parameters at any designated monitoring
station exceed the water quality criteria, the actions in accordance with the
Event and Action Plan summarized in Table 4.4 shall be carried out.
4.10.2
The ET Leader should assess the potential impacts on the water
sensitive receiver based on the monitoring data. The performance of the environmental
management system (i.e. of the overall EM&A programme) should be reviewed
by the ET Leader on a quarterly basis.
The findings of this review should be included in the quarterly EM&A
summary reports, together with any recommendations to improve the performance
of the EM&A programme.

5.1.1
The assessment of potential sewerage impacts arising from the proposed
cavern development has been assessed and the details are given in Section 7
of the EIA Report.
5.1.2
The total estimated Average Dry Weather Flow (ADWF) for the cavern is
about 8.4m3/day which is about 0.1% of the total ADWF generated in
ARQ Site. Thus, the additional ADWF of the cavern will not have any discernible
impacts to the trunk sewerage network for the ARQ Site.
5.1.3
Furthermore, no sewage treatment facilities, sewage pumping station and
rising main are proposed to be constructed in the cavern in view of the small
quantity sewage. The sewage flow from the cavern has been taken in account in
the design of ARQ sewerage system. Therefore, sewerage and sewage implications
arising from cavern development are not anticipated and no EM&A requirement
is considered necessary.
6.1.1
Construction and Demolition (C&D) materials, general refuse from
workforce and chemical waste would be generated during the construction phase.
It is the Contractor’s responsibility to ensure all the waste arising from the
Project is handled, stored and disposed of in accordance with good waste
management practices, relevant legislation and waste management guidelines.
Provided that the waste is handled, transported and disposed of using approved
methods and that the recommended good site practices are strictly followed,
adverse environmental impacts would not be expected.
6.2.1
The mitigation measures recommended in EIA Report should from the basis
of the site Waste management Plan (WMP) to be developed by the Contractor
during the construction stage.
6.2.2
It is recommended that the waste generated during the construction
activities should be audited regularly by the ET to determine if waste is being
managed in accordance with approved procedures and the site WMP. The audit
should look at all aspects of on-site waste management practices including
waste management practices including waste generation, storage, recycling,
transport and disposal. Apart from site inspection, documents including
licences, permits, disposal and recycling records should be reviewed and
audited for compliance with the legislation and contract requirements. In
addition, the routine site inspections should check the implementation of the
recommended good site practices and other waste management mitigation measures.
In order to monitor the disposal of C&D material at landfills and public
filling areas, as appropriate, and to control fly tipping, a trip-ticket system
should be included as one of the contractual requirements to be implemented by
an Environmental Team undertaking the Environmental Monitoring and Audit work.
6.2.3
With the appropriate handling, storage and disposal of waste arising
from the construction works as recommended in Appendix B, the potential
of adverse environmental impacts would be minimized. During the site
inspections, the ET should pay special attention to the issues relating to
waste management and check whether the Contractor has implemented the
recommended good site practices and mitigation measures.
6.3.1
Regular audits and site inspections should be carried out during
construction phase by the ER, ET and Contractor to ensure that the recommended
good site practices and the recommended mitigation measures in Appendix B
are properly implemented by the Contractor. The audits should concern all
aspects of on-site waste management practices including waste generation,
storage, recycling, transport and disposal. Apart from site inspection,
documents including licences, permits, disposal and recycling records should be
reviewed and audited for compliance with the legislation and contract
requirements.
6.3.2
The requirements of the environmental audit programme are set out in Section
8 of this Manual. The audit programme will verify the implementation status
and evaluate the effectiveness of the mitigation measures.
7.1.1
The EIA has recommended landscape and visual mitigation
measures to be undertaken during both the construction and operational phases
of the Project. The design,
implementation and maintenance of landscape mitigation measures should be
checked to ensure that any potential conflicts between the proposed landscape
measures and any other works of the project would be resolved as early as
practical without affecting the implementation of the mitigation measures.
7.2.1
The proposed mitigation measures of landscape and visual
impacts are summarised in the Implementation Schedule of Mitigation Measures in Appendix B. The landscape and
visual mitigation measures proposed should be incorporated in the detailed
landscape and engineering design. The construction phase mitigation measures
should be adopted from the commencement of construction and should be in place
throughout the entire construction period. Mitigation measures for the
operational phase should be adopted during the detailed design and be built as
part of the construction works so that they are in place on commissioning of
the Project.
7.2.2
The landscape and visual mitigation measures are elaborated
in Tables 7.1 and 7.2.
The plan for compensatory tree planting is indicated in Figure 7.1.

for the first 12-month establishment period. In the case that the site is still
not allocated after the establishment period, CEDD would liaise with relevant
government departments to agree on the subsequent maintenance agent of the
interim greening measures. Contractor would be responsible for the maintenance
of the interim greening measures before any agreement is made.
(2)
The
management and maintenance agencies of mitigation measures have been identified
in accordance with ETWB TC 2/2004. The agreement and approval of the
implementation, management and maintenance agencies of the Project will be
sought from relevant parties during detailed design stage of the project.
Contractor would be responsible for maintenance and management of trees,
vegetation and the associated facilities (e.g. irrigation system) within the
permanent site boundary. The maintenance matrix and responsible parties for
trees outside the permanent site boundary are yet to be confirmed. To
facilitate with the confirmation process, CEDD would be responsible for the
maintenance works before any agreement is made.
(3)
Mitigation
measures refer to Good Site Practices.
7.3.1
Site audits should be undertaken
during the construction and operational phase of the Project to check that the
proposed landscape and visual mitigation measures are properly implemented and
maintained as per their intended objectives. Site audits should be undertaken by the ET at least once every two weeks
during the construction period. The audits shall concern tree preservation, transplanting, compensation,
night-time glare control, management of work sites facilities and the
implementation of permanent landscape works in accordance with the proposed mitigation measures in the Table 9.7, Table 9.8
and Figures 9 - 12 of the EIA report and the implementation schedule
in Appendix B.
7.3.2

8.1.1 Site inspection is one of the
most effective tools to enforce the environmental protection requirements at
the works area by providing a direct mean to trigger and enforce specified
environmental protection and pollution control measures. Site inspection should
be undertaken regularly during the construction phase to ensure that
appropriate environmental protection and pollution control mitigation measures
are properly implemented for the activities associated with the Project.
8.1.2 The ET leader should be
responsible for formulating the environmental site inspection programme as well
as the deficiency and remedial action reporting system, and for carrying out
the site inspections. The proposal for rectification, if any, should be
prepared and submitted to the ET Leader and IEC by the Contractor.
8.1.3 Regular site inspections
should be carried out and led by the ER and attended by the Contractor and ET
at least once per week during the construction phase. The areas of inspection
should not be limited to the environmental conditions and the pollution control
and mitigation measures within the works area, it should also review the
environmental conditions of locations that are beyond the boundary of the works
area but are likely to be affected directly or indirectly by the construction
site activities of the Project. During the inspection, the following
information should be referred to:
Ÿ
The EIA Report and EM&A recommendations on environmental protection
and pollution control mitigation measures;
Ÿ
Ongoing results of the EM&A programme;
Ÿ
Works progress and programme;
Ÿ
Individual works methodology proposals (which should include the
proposal on associated pollution control measures);
Ÿ
Contract specifications on environmental protection and pollution
prevention control;
Ÿ
Relevant environmental protection and pollution control legislations;
and
Ÿ
Previous site inspection results undertaken by the ET and others
8.1.4 The Contractor should keep the
ER and ET Leader updated with all relevant environmental related information on
the construction contract necessary for him/her to carry out the site
inspections. Site inspection results and associated recommendations for
improvements to the environmental protection and pollution control efforts
should be recorded and followed up by the Contractor in an agreed time-frame.
The Contractor should follow the procedures and time-frame stipulated in the
environmental site inspection, and the deficiency and remedial action reporting
system to be formulated by the ET Leader, to report on any remedial measures
subsequent to the site inspections.
8.1.5 The ER, ET and the Contractor
should also carry out ad hoc site inspections if significant environmental
problems are identified. Inspections may also be required subsequent to receipt
of an environmental complaint, or as part of the investigation work, as
specified in the Event and Action Plan for the EM&A programme.
8.2.1 There are statutory and
contractual requirements on environmental protection and pollution control with
which construction activities must comply.
8.2.2 To ensure that the workers
are in compliance with the contractual requirements, all method statements of
works should be submitted by the Contractor to the ER for approval and to the
ET Leader for vetting to determine if sufficient environmental protection and
pollution control measures have been included. The implementation schedule of
mitigation measures is summarized in Appendix B.
8.2.3 The ER and ET Leader should
also review the progress and programme of the works to check that relevant
environmental legislations have not been violated, and that any foreseeable
potential for violating laws can be prevented.
8.2.4 The Contractor should provide
the update of the relevant documents to the ET Leader so that works checking
could be carried out effectively. The document should at least include the
updated Works Progress Reports, updated Works Programme, any application
letters for licences / permits under the environmental protection legislations,
and copies of all valid licences / permits. The site diary should also be
available for the inspection by the relevant parties.
8.2.5 After reviewing the
documentation, the ET Leader should advise the Contractor of any non-compliance
with contractual and legislative requirements on environmental protection and
pollution control so that they can timely take follow-up actions as
appropriate. If the follow-up actions may still result in violation of
environmental protection and pollution control requirements, the ER and ET
should provide further advice to the Contractor to take remedial actions to
resolve the problem.
8.2.6 Upon receipt of the advice,
the Contractor should undertake immediate action to remedy the situation. The
ER and ET should follow up to ensure that appropriate action has been taken in
order to satisfy contractual and legal requirements.
8.3.1 The following procedures
should be undertaken upon receipt of any environmental complaint:
i)
The Contractor to log complaint
and date of receipt onto the complaint database and inform the ER, ET and IEC
immediately;
ii) The Contractor to investigate, with the ER and ET, the complaint to
determine its validity, and assess whether the source of the problem is due to
construction works of the Project with the support of additional monitoring
frequency and stations, if necessary;
iii) The Contractor to identify remedial measures in consultation with
the IEC, ET and ER if a complaint is valid and due to the construction works of
the Project;
iv) The Contractor to implement the remedial measures as required by the
ER and to agree with the ET and IEC any additional monitoring frequency and
stations, where necessary, for checking the effectiveness of the remedial
measures;
v) The ER, ET and IEC to review the effectiveness of the Contractor’s
remedial measures and the updated situation;
vi) The ET/Contractor to undertake additional monitoring and audit to
verify the situation if necessary, and oversee that circumstances leading to
the complaint do not recur;
vii) If the complaint is referred by the EPD, the Contractor to prepare
interim report on the status of the complaint investigation and follow-up
action stipulated above, including the details of the remedial measures and
additional monitoring identified or already taken, for submission to EPD within
the time frame assigned by the EPD; and
viii) The ET to record the details of the complaint, results of the
investigation, subsequent actions taken to address the complaint and updated
situation including the effectiveness of the remedial measures, supported by
regular and additional monitoring results in the monthly EM&A reports.
9.1.1 Types of reports that the ET
should prepare and submit include Baseline Monitoring Report, Monthly EM&A
Reports and Final EM&A Review Report. In
accordance with Annex 21 of the EIAO-TM, a copy of the monthly and final review
EM&A reports should be made available to the Director of Environmental
Protection.
9.1.2 Reports can be provided in an
electronic medium upon agreeing the format with the ER and EPD.
9.2.1 The ET should prepare and
submit a Baseline Environmental Monitoring Report for water quality at least 4
weeks before the commencement of construction works for the Project. Copies of

9.6.1 The EM&A programme should
be terminated upon completion of those construction activities that have the
potential to result in a significant environmental impact.
9.6.2 Prior to the proposed
termination, the proposed termination should be implemented after the proposal
has been endorsed by the IEC, the Engineer and the Project Proponent followed
by final approval from the Director of Environmental Protection.
9.6.3 The ET Leader should prepare
and submit the Final EM&A Report which should contain at least the
following information:
i)
Executive summary (1-2 pages);
ii)
Drawings showing the Project area,
environmental sensitive receivers and locations of the monitoring stations;
iii)
Basic project information
including a synopsis of the project organisation, contacts of key management,
and a synopsis of works undertaken during the course of the Project;
iv)
A brief summary of EM&A
requirements including;
Ÿ
Environmental mitigation measures, as recommended in the EIA Report;
Ÿ
Environmental impact hypotheses tested;
Ÿ
Environmental quality performance limits (Action and Limit levels);
Ÿ
All monitoring parameters; and
Ÿ
Event and Action Plans;
v)
A summary of the implementation
status of environmental protection and pollution control / mitigation measures,
as recommended in the EIA Report, summarised in the updated implementation
schedule;
vi)
Graphical plots and the statistical
analysis of the trends of monitoring parameters over the course of the Project,
including the post-project monitoring for all monitoring stations annotated
against:
Ÿ
The major activities being carried out on site during the reporting
period;
Ÿ
Weather conditions during the reporting period; and
Ÿ
Any other factors which might affect the monitoring results;
vii)
A summary of non-compliance
(exceedances) of the environmental quality performance limits (Action and Limit
levels);
viii)
A review of the reasons for and
the implications of non-compliance including review of pollution sources and
working procedures as appropriate;
ix)
A description of the actions
taken in the event of non-compliance;
x)
A summary record of all
complaints received (written or verbal) for each media, liaison and
consultation undertaken, actions and follow-up procedures taken;
xi)
A summary record of
notifications of summons and successful prosecutions for breaches of the
current environmental protection / pollution control legislation, locations and
nature of the breaches, investigation follow-up actions taken and results;
xii)
A review of the validity of EIA
predictions and identification of shortcomings of the recommendations proposed
in the EIA Report; and
xiii)
Comments (for example, a review
of the effectiveness and efficiency of the mitigation measures and of the
performance of the environmental management system, that is, of the overall
EM&A programme);
xiv)
Recommendations and conclusions
(for example, a review of success of the overall EM&A programme to
cost-effectively identify deterioration and to initiate prompt effective
mitigation action when necessary).
9.7.1 No site-based documents (such
as monitoring field records, laboratory analysis records, site inspection
forms, etc) are required to be included in the
EM&A reporting documents. However, any such document should be properly
maintained by the ET and be ready for inspection upon request. All relevant
information should be clearly and systematically recorded in the document.
Monitoring data should also be recorded in magnetic media form, and the
software copy must be available upon request. All documents and data should be
kept for at least one year following the completion of the construction phase EM&A for each construction contract.
9.8.1 With reference to the Event
and Actions Plans, when the environmental quality performance limits are
exceeded and if they are proven to be valid, the ET should immediately notify
the IEC and EPD, as appropriate. The notification should be followed up with
advice to the IEC and EPD on the results of the investigation, proposed actions
and success of the actions take, with any necessary follow-up proposals. A
sample template for interim notification is presented in Appendix D.
