This
Environmental Monitoring and Audit
(EM&A) Manual (¡§the Manual¡¨) has been prepared by ERM-Hong Kong,
Limited (ERM) on behalf of The Castle Peak Power Company Limited (CAPCO). The Manual is a supplementary document
to the Environmental Impact Assessment (EIA) Report of the Additional Gas-fired
Generation Units Project at the Black Point Power Station (BPPS) (hereafter
referred to as the Project).
The
Manual has been prepared in accordance with the EIA Study Brief (No. ESB-286/2015) and the Technical Memorandum of the Environmental Impact Assessment Process
(EIAO-TM). The purpose of the
Manual is to provide information, guidance and instruction to personnel charged
with environmental duties and those responsible for undertaking EM&A work
during Project construction and operation.
It provides systematic procedures for monitoring and auditing the
environmental performance of the Project.
This
Manual contains the following information:
¡P
Responsibilities
of the Contractor(s) for Project construction, Environmental Team (ET), and the
Independent Environmental Checker (IEC) with respect to the EM&A
requirements during the course of the Project;
¡P
Project
organisation;
¡P
Requirements
with respect to the construction and operational programme schedule and the
necessary EM&A programme to track the environmental impact;
¡P
Details
of the methodologies to be adopted including field, laboratory and analytical
procedures, and details on quality assurance and quality control programme;
¡P
Preliminary
definition of Action and Limit levels;
¡P
Establishment
of Event and Action plans;
¡P
Requirements
for reviewing pollution sources and working procedures required in the event of
exceedances of applicable environmental criteria and/or receipt of complaints;
¡P
Requirements
for presentation of EM&A data and appropriate reporting procedures; and
¡P
Requirements
for review of EIA predictions and the effectiveness of the mitigation
measures/environmental management systems and the EM&A programme.
Black Point, where the BPPS
is situated, is located in the western-most part of the New Territories. It comprises a headland extending from
the east (land) to the west (sea) with granitic soil underneath, typical of the
Tuen Mun and Castle Peak
areas. The major development at
Black Point is the BPPS, which is the first natural gas-fired power plant in
Hong Kong. The BPPS is located to
the north of the headland on reclaimed land. Reclamation in Black Point was completed
in 1993 followed by construction of the BPPS and commencement of operation in
1996. BPPS is surrounded by
mountain to the east and south while to the immediate north and west is the
mouth of Deep Bay.
The proposed location for
the Project is within the existing boundaries of the BPPS site and the location
for each of the additional gas-fired generation units is illustrated in Figure 1.1.
The size of the land reserved for the additional generation units and
the associated facilities (the Project Site) is about 40,000 m2. The reserved land has been used for
material storage in warehouses and temporary structures. The northern half of the reserved land
is not occupied by any buildings or facilities, whereas the southern half is
occupied by a single storey warehouse.
There are no other facilities or utilities within the reserved land
except the surrounding chain link fence.
The scope of the Project
involves the phased construction and operation of up to two additional CCGT
units (with an installed capacity of up to 600 MW each) at the BPPS. The additional generation units will be
of combined
cycle gas turbine (CCGT) configuration using natural gas as the primary fuel,
thereby providing a cleaner source of electricity for Hong Kong. The Project is comprised of the
following key components:
¡P
Up
to two CCGT units;
¡P
Cooling
water intake facility and discharge facility;
¡P
Alternation
of temporary warehouse;
¡P
Civil
works and electrical / mechanical installation works for the CCGT units; and
¡P
Infrastructure
for making connections (fuel gas, fuel oil, electricity supply, water supplies,
auxiliary gas supplies, etc.) from existing plant equipment in BPPS and their
associated engineering works for enhancement / additions of equipment.
The location of these
components is shown in Figures 1.2a and 1.2b.
The
following elements of the Project addressed in this EIA Report are classified
as Designated Projects under the Environmental
Impact Assessment Ordinance (Cap. 499) (EIAO):
¡P
Installation
of additional gas-fired generation unit(s) in phases at the BPPS (Schedule 2,
Part I, Item D.1 - Public utility electricity power plant); and
¡P
If
a second unit is to be installed, a dredging operation less than 100 m from the
BPPS seawater intake location would be required (Schedule 2, Part I, Item
C.12(b) - A dredging operation which is less than 100 m from a seawater intake
point).
The
broad objective of this Manual is to define the procedures of the EM&A
programme for monitoring the environmental performance of the Project during
design, construction and operation.
The construction and operational impacts arising from the implementation
of the Project are specified in the EIA Report. The EIA Report also specifies mitigation
measures and construction practices that may be needed to confirm compliance
with the environmental criteria.
These mitigation measures and their implementation requirements are
presented in the Implementation Schedule of Mitigation Measures (Annex A).
The
main objectives of the EM&A programme are to:
¡P
provide
a database of environmental parameters against which to determine any short
term or long term environmental impacts;
¡P
provide
an early indication should any of the environmental control measures or
practices fail to achieve the acceptable standards;
¡P
confirm
that the mitigation recommendations of the EIA are included in the design of
the Project;
¡P
clarify
and identify potential sources of pollution, impact and nuisance arising from
the works for the responsible parties;
¡P
confirm
compliance with regulatory requirements, contract specifications and EIA study
recommendations;
¡P
confirm
compliance of environmental designs during the design phase of the Project with
the specifications stated in the EIA Report and the Environmental Permit (EP);
¡P
monitor
performance of the mitigation measures and to assess their effectiveness;
¡P
take
remedial action if unexpected issues or unacceptable impacts arise;
¡P
verify
the environmental impacts predicted in the EIA; and
¡P
audit
environmental performance.
The
scope of this EM&A programme is to:
For
both CCGT Unit No.1 and No.2:
¡P
implement
inspection and audit requirements for waste management;
¡P
liaise
with, and provide environmental advice (as requested or when otherwise
necessary) to construction site staff on the significance and implications of
the environmental monitoring data;
¡P
identify
and resolve environmental issues and other functions as they may arise from the
works;
¡P
check
and quantify the Contractor(s)¡¦s overall environmental performance,
implementation of Event and Action Plans (EAPs), and remedial actions taken to
mitigate adverse environmental effects as they may arise from the works;
¡P
conduct
monthly reviews of monitored impact data as the basis for assessing compliance
with the defined criteria and to verify that necessary mitigation measures are
identified and implemented, and to undertake additional ad hoc monitoring and
auditing as required by special circumstances;
¡P
evaluate
and interpret environmental monitoring data to provide an early indication
should any of the environmental control measures or practices fail to achieve
the acceptable standards, and to verify the environmental impacts predicted in
the EIA;
¡P
manage
and liaise with other individuals or parties concerning other environmental
issues deemed to be relevant to the construction process;
¡P
conduct
regular site inspections and audits of a formal or informal nature to assess:
(i) the
level of the Contractor(s)¡¦s general environmental awareness;
(ii) the
Contractor(s)¡¦s implementation of the recommendations in the EIA and their
contractual obligations;
(iii) the
Contractor(s)¡¦s performance as measured by the EM&A;
(iv) the
need for specific mitigation measures to be implemented or the continued usage
of those previously agreed;
(v) to
advise the site staff of any identified potential environmental issues; and
¡P
produce
monthly EM&A reports which summarise project monitoring and auditing data,
with full interpretation illustrating the acceptability or otherwise of any
environmental impacts and identification or assessment of the implementation
status of agreed mitigation measures.
¡P
establish
baseline water quality levels at specified locations and implement monitoring
requirements for water quality monitoring programme; and
¡P
implement
monitoring requirements for marine mammal monitoring programme.
The
preliminary construction programme is given in Figure 1.3. The locations of works are shown in Figure 1.1.

(1) EM&A
requirements in the design phase shall include confirmation on the compliance
for environmental designs which were specified in the EIA Report and the EP
for all parameters. (2) For
the construction phase of the CCGT Unit No.1, no marine construction works
would be required. Therefore
construction phase marine water quality monitoring exercise is only required
for the construction phase of the CCGT Unit No.2. |
Potential environmental
impacts, which were identified during the EIA study and are associated with the
construction phase of the Project, will be addressed through the monitoring and
controls specified in this EM&A Manual and in the construction contracts.
During the construction
phases of the Project (for both CCGT Units No.1 and
No.2), air
quality, hazard to human life, noise, water quality, waste management, land
contamination, ecology, and landscape and visual will be subject to EM&A,
with environmental monitoring being undertaken for water quality for the
construction phase of the CCGT Units No.2 as determined in the
EIA. Monitoring of the
effectiveness of the mitigation measures will be achieved through the
environmental monitoring programme as well as through site inspections. The inspections will include within
their scope, mechanisms to review and assess the Contractor(s)¡¦s environmental
performance, ensuring that the recommended mitigation measures have been
properly implemented, and that the timely resolution of received complaints are
managed and controlled in a manner consistent with the recommendations of the
EIA Report.
The environmental
monitoring work throughout the Project will be carried out in accordance with
this Manual and reported by the ET.
Monitoring works is only required during the construction phase of CCGT
Unit No.2 and will cover water quality and marine mammal monitoring.
Action and Limit (A/L)
Levels are defined levels of impact recorded by the environmental monitoring
activities which represent levels at which a prescribed response is
required. Since environmental
monitoring is only required for the construction phase of CCGT Unit No.2,
details on these Levels are provided in the Water Quality Section (Section 6).
The purpose of the Event
and Action Plans (EAPs) is to provide, in association with the monitoring and
audit activities, procedures for ensuring that if any significant environmental
incident occurs, the cause will be quickly identified and remediated. This also applies to the exceedances of
A/L criteria identified in the EM&A programme.
In addition to monitoring,
as a means of assessing the ongoing performance of the Contractor(s) for
Project construction, the ET will undertake site inspections of the compliance
with stipulated procedures and on-site practices. The primary objective of the inspection
and audit programme will be to assess the effectiveness of the environmental
controls established by the Contractor(s) and the implementation of the
environmental mitigation measures recommended in the EIA Report. The IEC will undertake site audits on as
need basis to assess the performance of the Contractor(s).
Whilst the audit and
inspection programme will complement the monitoring activity, the criteria
against which the audits will be undertaken will be derived from the Clauses
within the Contract Documents which seek to enforce the recommendations of the
EIA Report and the EM&A Manual.
The findings of site
inspections and audits will be made known to the Contractor(s) at the time of
the inspection to enable the rapid resolution of identified
non-conformities. Non-conformities,
and the corrective actions undertaken, will also be reported in the monthly
EM&A Reports.
Section
14 of this Manual presents details of
the scope and frequency of on-site inspections and defines the range of issues
that the audit protocols will be designed to address.
Enquiries, complaints and
requests for information may occur from a wide range of individuals and
organisations including members of the public, Government departments, the
press and community groups.
All enquiries concerning
the environmental impacts of the Project, irrespective of how they are
received, will be reported to CAPCO and IEC and directed to the ET who should
set up procedures for handling, investigation and storage of such
information. The following steps
should be followed:
(1) The
ET Leader should notify the IEC and CAPCO of the nature of the enquiry.
(2) An
investigation should be initiated to determine the validity of the complaint
and to identify the source(s) of the problem.
(3) The
ET Leader should undertake the following steps, as necessary:
¡P
investigate
and identify source(s) of the problem, with assistance from CAPCO and relevant
Contractor(s);
¡P
if
considered necessary by CAPCO following consultation with the IEC, undertake
additional monitoring to verify the existence and severity of the alleged
complaint;
¡P
identify
necessary remedial measures and implement as soon as possible;
¡P
if
the complaint is transferred from EPD, submit interim report to EPD on status
of the complaint investigation and follow-up action within the time frame
assigned by EPD;
¡P
repeat
the monitoring to verify effectiveness of mitigation measures; and,
¡P
repeat
review procedures to identify further possible areas of improvement if the
repeat monitoring results continue to substantiate the complaint.
(4) The
outcome of the investigation and the action taken will be documented on a
complaint log (Annex B). A formal response to each complaint
received will be prepared by the Contractor(s) within five working days and
submitted to CAPCO, in order to notify the concerned person(s) that action has
been taken.
(5) 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 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.
The complainant will be
notified of the findings, and audit procedures will be put in place to verify
that the issue does not recur.
Baseline, construction
phase and post-construction phase monitoring, monthly, and annual/final reports
will be prepared and certified by the ET Leader and verified by the IEC. The reports will be submitted to CAPCO
and EPD. The monthly reports will
be prepared and submitted within two weeks of the end of each calendar month.
The cessation of EM&A
programme is subject to the satisfactory completion of the EM&A Final
Report, agreement with the IEC and approval from EPD.
Based on the findings of
the EIA, air and water quality monitoring during operation phase of both CCGT
Units is considered necessary.
Monitoring of any planting works should also continue over their
establishment period, which may extend into the operation phase, and will be
covered by regular site inspections.
Other operational licences will require specific monitoring or audit
conditions or practices, and a non EIA EM&A practice will need to be put in
place.
The EIA study concluded
that no adverse fugitive dust impact is anticipated during the construction of
CCGT Units No.1 and No.2, and dust monitoring is considered not necessary. However, it is recommended to conduct
regular environmental site audit, i.e. on weekly basis, to confirm the
implementation of the dust control measures and good site practices as
recommended in Section 4.10.1 of the
EIA Report throughout the construction of these two units. These measures are also summarised in the
Implementation Schedule provided in Annex A.
Based on the prediction of
the air quality modelling exercise conducted under this EIA study, no adverse
air quality impact is anticipated during the operation of the additional CCGT
units. Air pollutants of the
exhaust gas streams emitted from the stacks of the CCGT units will be
continuously monitored and recorded by means of Continuous Emission Monitoring
System (CEMS) per the licence requirements.
Existing continuous
monitoring of ambient concentrations of SO2, NO and NO2
will be continued at the current CLP¡¦s air quality monitoring stations, as
required by specific emissions licences.
The
EIA study concluded that the individual risk and societal risks posed by the
proposed Project and the existing BPPS facilities for both construction and
operation phases are acceptable and in compliance with risk criteria in Section 2 of Annex 4 of EIAO-TM. No unacceptable risks are foreseen as a
result of the operation of the proposed Project. No mitigation measures are thus deemed
necessary and no monitoring will be required for the construction and operation
phases. Safety management measures
are recommended to further manage and minimise the external hazards from
constructions activities risk during the construction phase of the two
units. They are summarised in the
Implementation Schedule provided in Annex A.
CAPCO
is a registered gas supply company and will periodically review and update the
risk assessment associated with the operations of the natural gas facilities
under the Gas Safety Ordinance to
demonstrate that the members of the public are not exposed to undue risks.
Noise monitoring is considered not necessary during both construction and
operation phases of the proposed Project.
Monthly site inspections and audits are recommended to be carried out
during the construction phase of the two units in order to confirm that
regulatory requirements are being met.
In accordance with the
recommendations of the EIA, water quality EM&A is required during dredging
at the cooling water intake and discharge outfall for construction of CCGT Unit
No.2 and operation phase maintenance dredging. In addition, baseline water quality
monitoring will be required prior to the commencement of marine construction
activities of CCGT Unit No.2. The following sections provide details of the
water quality monitoring to be undertaken by the ET to verify the distance of
sediment and thermal plume dispersion and to identify whether the potential
exists for any indirect impacts to occur to ecological sensitive receivers. The water quality monitoring programme
will be carried out to allow any deteriorating water quality to be readily
detected and timely action taken to rectify the situation. The status and locations of water
quality sensitive receivers and the marine works location may change after
issuing this Manual. If required,
the ET in consultation with IEC will propose updated monitoring locations and
seek approval from EPD.
Water quality monitoring
for the Project can be divided into the following stages:
¡P
Marine
water quality monitoring for dredging activities during construction phase of
the CCGT Unit No.2;
¡P
Marine
water quality monitoring on first year of commissioning of the CCGT Unit No.1;
¡P
Marine
water quality monitoring on first year of commissioning of the CCGT Unit No.2;
¡P
Marine
water quality monitoring for maintenance dredging during operation phase of the
CCGT Unit No.2 and
¡P
Regular
monitoring of effluent quality.
The parameters that have
been selected for measurement in situ and in the laboratory are those that were
either determined in the EIA to be those with the most potential to be affected
by the construction works or are a standard check on water quality
conditions. Parameters to be
measured in the construction phase, operation phase and effluent quality
monitoring are listed in Table 6.1.

In addition to the water quality
parameters, other relevant data will also be measured and recorded in Water
Quality Monitoring Logs, including the location of the sampling stations, water
depth, time, weather conditions, sea conditions, tidal stage, current direction
and velocity, special phenomena and work activities undertaken around the
monitoring and works area that may influence the monitoring results. A sample data record sheet is shown in Annex B for reference.
For water quality
monitoring, the following equipment will be used:
¡P
Dissolved
Oxygen and Temperature Measuring Equipment - The instrument will be a portable,
weatherproof dissolved oxygen measuring instrument complete with cable, sensor,
comprehensive operation manuals, and will be operable from a DC power

in length. Sufficient stocks of
spare electrodes and cables shall be available for replacement where necessary
(e.g. YSI model 59 DO meter, YSI 5739 probe, YSI 5795A submersible stirrer with
reel and cable or an approved similar instrument).
¡P
Turbidity
Measurement Equipment
- The instrument will be a portable, weatherproof turbidity-measuring unit
complete with cable, sensor and comprehensive operation manuals. The equipment will be operated from a DC
power source, it will have a photoelectric sensor capable of measuring
turbidity between 0 - 1000 NTU and will be complete with a cable with at least
35 m in length (for example Hach 2100P or an approved
similar instrument).
¡P
Salinity
Measurement Instrument
- A portable salinometer capable of measuring
salinity in the range of 0 - 40 ppt will be provided for measuring salinity of
the water at each monitoring location.
¡P
Water
Depth Gauge
¡V A portable, battery-operated echo sounder (for example Seafarer 700 or a
similar approved instrument) will be used for the determination of water depth
at each designated monitoring station.
This unit will preferably be affixed to the bottom of the work boat if
the same vessel is to be used throughout the monitoring programme. The echo sounder should be suitably
calibrated. The ET shall seek
approval for their proposed equipment with the client prior to deployment.
¡P
Current
Velocity and Direction
¡V No specific equipment is recommended for measuring the current velocity and
direction. The environmental
contractor shall seek approval of their proposed equipment with the client
prior to deployment.
¡P
Positioning
Device
¡V A Global Positioning System (GPS) shall be used during monitoring to allow
accurate recording of the position of the monitoring vessel before taking
measurements. The Differential GPS,
or equivalent instrument, should be suitably calibrated at appropriate
checkpoint (e.g. Quarry Bay Survey Nail) to verify that the monitoring station
is at the correct position before the water quality monitoring commence.
¡P
Water
Sampling Equipment
- A water sampler, consisting of a PVC or glass cylinder of not less than two
litres, which can be effectively sealed with cups at both ends, will be used
(e.g. Kahlsico Water Sampler 13SWB203 or an approved
similar instrument). The water
sampler will have a positive latching system to keep it open and prevent
premature closure until released by a messenger when the sampler is at the
selected water depth.
¡P
Total
Residual Chlorine
- Total residual chlorine (TRC) shall be measured in-situ using approved test
kit.
All in situ monitoring instruments will be checked, calibrated and
certified by a laboratory accredited under the Hong Kong Laboratory
Accreditation Scheme (HOKLAS) ([1])
or any other international accreditation scheme before use, and subsequently re-calibrated
at monthly intervals throughout the stages of the water quality
monitoring. Responses of sensors
and electrodes will be checked with certified standard solutions before each
use.
On-site calibration of
field equipment shall follow the ¡§Guide
to On-Site Test Methods for the Analysis of Waters¡¨, BS 1427: 2009. Sufficient stocks of spare parts shall
be maintained for replacements when necessary. Backup monitoring equipment shall also
be made available so that monitoring can proceed uninterrupted even when
equipment is under maintenance, calibration etc.
All laboratory work shall
be carried out in a HOKLAS accredited laboratory. Sufficient volume of each water sample
shall be collected at the monitoring stations for carrying out the laboratory
analyses. Using chain of custody
forms, collected water samples will be transferred to an HOKLAS accredited
laboratory for immediate processing.
The determination work shall start within the next working day after collection
of the water samples. The
laboratory measurements shall be provided to the client within 5 working days
of the sampling event. Analytical
methodology and sample preservation of other parameters will be based on the
latest edition of Standard Methods for the Examination of Waste and Wastewater
published by American Public Health Association (APHA), American Water Works
Association (AWWA) and methods by USEPA, or suitable method in accordance with
requirements of HOKLAS or another internationally accredited scheme. 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 shall be in accordance with requirements of HOKLAS or
another internationally accredited scheme.
Parameters for laboratory
measurements, their standard methods and their detection limits are presented
in Table 6.2.

Cooling water effluent from
BPPS shall be collected at a suitable location before discharge. The sampling location should be agreed
with CAPCO and EPD, and should fulfil the following requirements:
¡P
Effluent
collected at the sampling location is representative to the effluent discharged
at the outfall diffuser;
¡P
Sampling
works at the sampling location would not interfere with the normal operation of
the BPPS; and
¡P
Sampling
works at the sampling location would not induce safety hazard.
The status and locations of
water quality sensitive receivers and the monitoring sites may change after
issuing this Manual. If such cases
exist, the ET shall propose updated monitoring locations and seek approval from
the IEC and EPD.
When alternative monitoring
locations are proposed, they shall be chosen based on the following criteria:
¡P
at
locations close to and preferably at the boundary of the site activities as
indicated in the EIA Report, which are likely to have water quality impacts;
¡P
close
to the sensitive receptors which are directly or likely to be affected;
¡P
for
monitoring locations located in the vicinity of the sensitive receptors, care
should be taken to cause minimal disturbance during monitoring; and
¡P
control stations which are at locations
representative of the project site in its undisturbed condition.
Baseline conditions for
water quality shall be established and agreed with the IEC and the EPD prior to
the commencement of marine dredging works for CCGT Unit No.2. The purpose of the baseline monitoring
is to establish ambient conditions prior to the commencement of the dredging
works and to demonstrate the suitability of the proposed control monitoring
stations. The baseline conditions shall normally be established by measuring
the water quality parameters specified above.
The measurements shall be
taken at all designated monitoring stations including control stations, at both
mid-ebb and mid-flood tides on the same day for a minimum of 3 days per week
for 4 weeks prior to the commencement of the construction works. Measurements shall be taken at each station
at any time. The interval between
two sets of monitoring shall not be less than 36 hours.
No construction activities
shall be on-going in the vicinity of the stations during the baseline
monitoring. The ET shall be
responsible for undertaking the baseline monitoring and submitting the results
within 10 working days from the completion of the baseline monitoring work.
In exceptional cases when
insufficient baseline monitoring data or questionable results are obtained, the
ET shall seek approval from the IEC and the EPD on an appropriate set of data
to be used as baseline reference.
The baseline monitoring
schedule shall be issued to the IEC and EPD at least 1 week prior to the
commencement of baseline monitoring.
During periods when there
are dredging works, impact monitoring shall be undertaken at the monitoring
stations as shown in Figure 6.1 and Table 6.3 three times a week. Monitoring at each station would be
undertaken at both mid-ebb and mid-flood tides on the same day. The tidal range selected for the
baseline monitoring will be at least 0.5 m for both flood and ebb tides as far
as practicable. The interval
between two sets of monitoring would not be less than 36 hours. The monitoring frequency would be
increased in the case of exceedances of Action/Limit Levels if considered
necessary by ET. Monitoring
frequency would be maintained as far as practicable.
The monitoring
location/position, time, water depth, water temperature, salinity, weather
conditions, sea conditions, tidal stage, special phenomena and work underway at
the marine works site will be recorded.
Upon completion of all
marine construction activities, a post-construction water quality monitoring
exercise would be carried out for four weeks, in the same manner as the
baseline monitoring.
Upon commencement of CCGT
Unit No.1 and No.2, an operation phase water quality monitoring exercise shall
be carried out for one year, in the same manner as the baseline monitoring
except at a frequency of once per week.
Monitoring of cooling water
effluent quality shall be conducted daily for one year at specific location
agreed by IEC prior to the commissioning of the CCGT Unit No.1 or No.2. The monitoring exercise shall be conducted
in accordance with the effluent parameters and standards stipulated by the WPCO
Discharge Licence conditions and therefore would not be further detailed in
this Manual. The monitoring
requirement for the monitoring of cooling water effluent quality shall be
approved by EPD. The effluent results
reflect whether the effluent quality is in compliance with the Discharge
Licence requirements. In case of
non-compliance, suitable actions shall be undertaken to notify the plant
operator for the non-compliance and identify the cause for the non-compliance. Corrective and remedial actions shall be
implemented to improve the effluent quality. The non-compliance events and preventive
measures shall be documented.
In case maintenance
dredging at the seawater intake and / or discharge outfall of CCGT Unit No.2 is
required, the same water quality monitoring exercise, including baseline
monitoring (Section 6.3.1), impact monitoring (Section 6.3.2) and post-construction monitoring (Section 6.3.3) shall be conducted to before, during
and after the dredging works.
For baseline, construction
phase and operation phase monitoring, each station will be sampled and
measurements/ water samples will be taken at three depths, 1 m below the sea
surface, mid-depth and 1 m above the seabed. For stations that are less than 3 m in
depth, only the mid-depth sample shall be taken. For stations that are less than 6 m in
depth, only the surface and seabed sample shall be taken. For in
situ measurements, duplicate readings shall be made at each water depth at
each station. Duplicate water
samples shall be collected at each water depth at each station.
The effluent sampling
should be planned carefully to ensure appropriate volume of effluent
sub-samples is collected to prepare sufficient amount of flow-weighted
composite effluent sample for carrying out subsequent chemical analysis and
testing.
Water quality monitoring will
be evaluated against Action and Limit Levels. The key assessment parameters are
dissolved oxygen, temperature, suspended solids and TRC and thus Action and
Limit Levels based on the assessment criteria are identified for these. However turbidity can also provide
valuable instantaneous information on water quality and thus Action and Limit
Levels are also recommended for this parameter to facilitate quick responsive
action in the event of any apparent unacceptable deterioration attributable to
the works. The proposed Action and
Limit Levels are shown in Table 6.4.
Action and Limit levels are
used to determine whether operational modifications are necessary to mitigate
impacts to water quality. In the
event that the levels are exceeded, appropriate actions in Event and Action
Plan (Table
6.5) should be undertaken and a review of
works will be carried out by the Contractor(s).
Any noticeable change to
water quality will be recorded in the monitoring reports and will be
investigated and remedial actions will be undertaken to reduce impacts. Particular attention will be paid to the
Contractor(s)¡¦s implementation of the recommended mitigation measures.
Site audit will be
conducted throughout the construction phase of CCGT Units No.1 and No.2 to
confirm the implementation of the water pollution control measures and good
site practices as recommended in Annex A.

The construction of the
proposed additional CCGT units is expected to generate the following types of
waste during the construction phase:
¡P
Dredged
marine sediment (for CCGT Unit No.2 only);
¡P
Excavated
materials;
¡P
Construction
& demolition (C&D) materials;
¡P
Chemical
waste; and
¡P
General
refuse.
Mitigation measures, where
appropriate, have been recommended as part of the EIA to avoid or reduce
potential adverse environmental impacts associated with handling, collection
and disposal of waste arising from the construction of the proposed Project.
Waste management will be
the Contractor(s)¡¦s responsibility and wastes produced during the construction
phase will be managed in accordance with appropriate waste management practices
and EPD¡¦s regulations and requirements.
Auditing of waste
management practices during regular site inspections will confirm that these
solid and liquid wastes generated during construction are not disposed of into
the surrounding storm drains. The
construction Contractor(s) will be responsible for the implementation of any
mitigation measures to reduce waste or redress issues arising from the waste
materials.
The waste management
practices and recommended mitigation measures will be incorporated into a Waste
Management Plan (WMP) as stated in the ETWB
TC(W) No. 19/2005, Environmental Management on
Construction Sites and C&D Material Management Plan (C&DMMP) for
the Project for managing the different types of wastes by the Contractors on
site. The WMP will become a part of
the Environmental Management Plan (EMP), as required under the quoted ETWB TCW No. 19/2005. The contractor is required to prepare
the EMP and submit it CAPCO for approval and then implement the EMP
accordingly. The WMP will also be
certified by the ET Leader and verified by the IEC as conforming to the
information and recommendations contained in the EIA Report.
The WMP shall describe the
arrangements for avoidance, reuse, recovery and recycling, storage, collection,
treatment, the estimated rate of construction and demolition materials
generation and disposal, and the recommended mitigation measures on waste
management as set out in Section 8.5
of the EIA Report. The WMP shall
indicate the disposal arrangements and locations of C&D materials and other
wastes.
A Trip Ticket system will
be included in the WMP. Surplus
excavated spoil and other wastes will not be disposed at any other designated
disposal locations unless otherwise approved in writing by EPD, Secretary of
Public Fill Committee and/or other authorities as appropriate.
The Implementation Schedule
(Annex A) provides details on the appropriate mitigation
measures for avoiding and preventing adverse environmental impacts associated
with dredged marine mud, C&D materials, chemical wastes, general refuse and
sewage from the workforce. The WMP
will be refined and updated as more detailed information is generated on the
volume of dredged marine mud and the agreed disposal arrangements. Similarly, it will be regularly
reviewed, and updated as appropriate, throughout the course of the construction
works to confirm that it remains current with the latest detailed information
and works practices.
The WMP will also outline
the requirements for a waste audit program to verify that the measures outlined
in the plan are effectively implemented and adhered too.
The construction
Contractor(s) must confirm that the necessary disposal permits or licences are
obtained from appropriate authorities in accordance with the various
Ordinances. In addition to the
monthly joint inspections/ audits, each construction Contractor(s) will
designate a member of staff as being responsible for routine inspections and
audits of on-site waste management practices, with reference to the relevant
legislation and guidelines as well as the recommendations given in the
Implementation Schedule contained in Annex A of this Manual, and defined below:

Note:
ET ¡V Environmental Team, IEC ¡V Independent Environmental Checker
Based on the result of the
SI conducted under this EIA, no land contamination was identified within the
Site. Therefore, no adverse environmental
impact in respect of land contamination within the Site is expected. No mitigation measures are recommended.
During construction stage,
good house-keeping practices shall be maintained by the contractor(s) to
minimise the risk of land contamination due to construction activities,
including but not limited to the following:
¡P
Minimise
the chemical stock within the Site, only store the amount of chemicals needed;
¡P
Designated
chemical/ chemical waste storage shall be established on concrete paved ground,
as far as practicable. Secondary
containments shall be provided for storage of chemicals/ chemical wastes;
¡P
Conduct
regular maintenance and inspection on plants and equipment, particularly those
involve the use of fuel, hydraulic oil or any sort of chemicals; and
¡P
Divert
rainfall and surface run-off around construction areas.
To ensure that the
construction contractor(s) has (have) implemented these recommendations,
regular site inspections and audits during construction phase of the two units
shall be conducted. The visual
inspections/audits will look at all aspects of construction activities that
disturb soil. The first
inspection/audit will be conducted at the commencement of the construction
works. The recommended good
house-keeping practices for construction phase are summarised in the
Implementation Schedule provided in Annex A.
The assessment indicates
that unacceptable construction phase impacts and operation phase impacts are
not expected to occur to terrestrial and marine ecological resources. Appropriate mitigation measures are
proposed in the EIA to control the environmental impacts to ecology to within
acceptable levels. Impacts of
construction activities will be monitored through impacts to water
quality. Measures recommended to
minimise impacts on water quality are also expected reduce impacts on marine
ecological resources. Therefore no
ecology specific EM&A activities are considered necessary for both
construction and operation phases.
In accordance with the
recommendations of the EIA, specific measures and additional precautionary
measures will be instituted for marine mammals during the construction works of
CCGT Unit No.2. These are
summarised in the Implementation Schedule of Mitigation Measures (Annex A).
As no unacceptable impacts
have been predicted to occur during the construction and operation of this
Project, monitoring of fisheries resources during these project phases is not
considered necessary.
Monitoring activities
designed to detect and mitigate impacts to water quality during construction
and operation phases are also expected to serve to protect against impacts to
fisheries. The details of the water
quality monitoring programme are presented in the EM&A Manual.
The
LVIA recommended a series of measures for the design, construction and
operation phase to mitigate the landscape and visual impacts of the Project and
help enhance these aspects of the site.
Details of all the recommended mitigation measures are summarised in the
Implementation Schedule provided in Annex A.
Measures
to mitigate impacts from the Project on landscape and visual resources
recommended in the EIA Report should be implemented as early as possible. Any soft landscaping works, in
particular relocating moveable planters to agreed locations, are recommended to
be implemented prior to construction works and overseen by the qualified
landscape professional who should ensure re-location to suitable location and if
any planted vegetation within the moveable planters deteriorate in health
during the construction period, suitable measures are taken to rectify this,
including replacement of any plants that die. Landscape and visual mitigation will be
monitored through the site inspection and audit programme during the
construction phase. No operation
phase EM&A programme is required.
As no impacts to
terrestrial and marine cultural heritage resources are expected, no mitigation
measure and environmental monitoring is required.
No unacceptable health
impacts associated with the operation of the proposed Project is anticipated
from the Project. No EM&A
activities related to health impact at the representative Human Sensitive
Receivers are required.
Site inspections provide a
direct means to assess and confirm that the Contractor(s)¡¦s environmental
protection and pollution control measures are in compliance with the contract
specifications. The site inspection
will be undertaken routinely by the ET throughout the construction phases of
CCGT Unit No.1 and No.2 to verify that appropriate environmental protection and
pollution control mitigation measures are properly implemented in accordance
with the EIA. In addition, the ET
will be responsible for defining the scope of the inspections, detailing any
deficiencies that are identified, and reporting any necessary action or
additional mitigation measures that were implemented as a result of the
inspection.
Regular site inspections
will be carried out by the ET each month.
The IEC will also undertake monthly site audit to assess the performance
of the Contractor(s). The areas of
inspection will not be limited to the site area and should also include the
environmental conditions outside the site which are likely to be affected,
directly or indirectly, by the site activities. The ET will make reference to the
following information while conducting the inspections:
¡P
the
EIA and EM&A recommendations on environmental protection and pollution
control mitigation measures;
¡P
ongoing
results of the EM&A programme;
¡P
work
progress and programme;
¡P
individual
works methodology proposals;
¡P
the
contract specifications on environmental protection;
¡P
the
relevant environmental protection and pollution control laws; and
¡P
previous site inspection results.
The Contractor(s) will
update the ET with relevant information on the construction works prior to
carrying out the site inspections.
The site inspection results will be submitted to the IEC, CAPCO and the
Contractor(s) within 24 hours.
Should actions be necessary, the ET will follow up with recommendations
on improvements to the environmental protection and pollution control works and
will submit these recommendations in a timely manner to the IEC, CAPCO and the
Contractor(s).
They will also be presented, along with the remedial actions taken, in
the monthly EM&A report. The
Contractor(s) will follow the procedures and time frame stipulated in the
environmental site inspection for the implementation of mitigation proposal and
the resolution of deficiencies in the Contractor(s)¡¦ EMS. An action reporting system will be
formulated and implemented to report on any remedial measures implemented
subsequent to the site inspections.
Ad hoc site inspections
will also be carried out by the ET and site audits by the IEC if significant
environmental issues are identified.
Inspections and audits may also be required subsequent to receipt of an environmental
complaint or as part of the investigation work as specified in the Action Plan
for environmental monitoring and audit.
There are contractual
environmental protection and pollution control requirements as well as
environmental protection and pollution control laws in Hong Kong with which the
construction activities will comply.
In order that the works are
in compliance with the contractual requirements, the works method statements
submitted by the Contractor(s) to CAPCO for approval will be sent to the ET for
review.
The ET will also review the
progress and programme of the works to check the regulatory compliance.
The Contractor(s) will
regularly copy relevant documents to the ET so that the checking and auditing
work can be carried out. The
relevant documents are expected to include at a minimum the updated Work
Progress Reports, the updated Works Programme, the application letters for
different licence/permits under the environmental protection laws and all valid
licences/permits. The site diary will also be available for the ET inspection
upon request.
After reviewing the
document, the ET will advise the IEC, CAPCO and the Contractor(s) of any
non-compliance from the contractual and legislative requirements on environmental
protection and pollution control for follow-up actions. The ET will also advise the IEC, the
Contractor(s) and CAPCO on the current status on licence/permit applications
and any environmental protection and pollution control preparation works that
may not be suitable for the works programme or may result in potential
nonconformity of environmental protection and pollution control requirements.
Upon receipt of the advice,
the Contractor(s) will undertake immediate action to remedy the situation. The ET, IEC and CAPCO will follow up to
confirm that appropriate action will be taken by the Contractor(s) in order
that the environmental protection and pollution control requirements are
fulfilled.
The ET will undertake the
following procedures (see Figure 14.1)
upon receipt of a complaint:
(1) log
complaint and date of receipt into the complaint database and inform the IEC
immediately;
(2) investigate
the complaint and discuss with the Contractor(s) and CAPCO to determine its
validity and to assess whether the source of the issue is due to works
activities;
(3) if
a complaint is considered valid due to the works , the ET will identify
mitigation measures in consultation with the Contractor(s), CAPCO and IEC;
(4) if
mitigation measures are required, the ET will advise the Contractor(s)
accordingly;
(5) review
the Contractor(s)'s response on the identified mitigation measures and the
updated situation;
(6) if
the complaint is transferred from EPD, an interim report will be submitted to
EPD on the status of the complaint investigation and follow-up action within
the time frame assigned by EPD;
(7) undertake
additional monitoring and audit to verify the situation if necessary and
confirm that any valid reason for complaint does not recur;
(8) 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
(9) record
the complaint, investigation, the subsequent actions and the results in the
Monthly EM&A Reports.
During the complaint
investigation work, the ET, Contractor(s) and CAPCO will cooperate with the IEC
in providing the necessary information and assistance for completion of the
investigation. If mitigation
measures are identified in the investigation, the Contractor(s) will promptly
carry out the mitigation measures.
CAPCO will approve the proposed mitigation measures and the ET and IEC
will check that the measures have been carried out by the Contractor(s).
The ET Leader will keep a
contemporaneous log-book of each and every instance or circumstance or change
of circumstances which may affect the EIA and every
non-compliance from the recommendations of the EIA Report or the
EP. The ET Leader will notify the
IEC within one working day of the occurrence of any such instance or
circumstance or change of circumstance.
The ET Leader¡¦s log-book will be kept readily available for inspection
by persons assisting in supervision of the implementation of the EIA Report
recommendations (such as CAPCO, IEC and Contractor(s)) and the EP or by EPD or
his authorised officers.
Reports can be provided in
an electronic medium upon agreeing the format with CAPCO and EPD. The monitoring data (baseline and
impact) will also be made available through a dedicated internet website that
would be agreed with relevant authority.
Types of reports that the
ET Leader will prepare and submit include baseline monitoring report,
post-construction water quality monitoring report, monthly EM&A report,
quarterly EM&A summary report, final EM&A review report, and water
