1.2                                    Project Description

1.2.1                              Site Location

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.

1.2.2                              Project Scope

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).

1.3                                    Objective of the EM&A

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.

1.4                                    Scope of the EM&A Programme

The scope of this EM&A programme is to:

For both CCGT Unit No.1 and No.2:

Notes:

¡§ (SI) ¡¨= Site Inspection forms the main checking method;  ¡§- ¡§ = no EM&A required

(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.

 

2.2                                    Construction Phase EM&A

2.2.1                              General

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.

2.2.2                              Environmental Monitoring

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.

2.2.3                              Action and Limit Levels

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).

2.2.4                              Event and Action Plans

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.

2.2.5                              Site Inspections

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.

2.2.6                              Enquiries, Complaints and Requests for Information

Enquiries, complaints and requests for information may occur from a wide range of individuals and organisations including members of the public, Government departments, the press and 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.

2.2.7                              Reporting

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.

2.2.8                              Cessation of EM&A

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.

2.3                                    Operation Phase EM&A

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.

3                                          Air Quality

3.1                                    Construction Phase

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.

3.2                                    Operation Phase

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.

4                                          Hazard to Human Life

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.

 

 

 

5                                          Noise

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.

6                                          Water Quality

6.1                                    Introduction

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;

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.

6.2.2                              Monitoring Equipment

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 source.  It will be capable of measuring: dissolved oxygen levels in the range of 0 - 20 mg L-1 and 0 - 200% saturation; and a temperature of 0 - 45 degrees Celsius.  It shall have a membrane electrode with automatic temperature compensation complete with a cable of not less than 35 m 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.

6.2.3                              Sampling / Testing Protocols

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.

6.2.4                              Laboratory Measurement and Analysis

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.

6.3                                    Sampling Frequency

6.3.1                              Baseline Monitoring

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.

6.3.2                              Construction Phase

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.

6.3.3                              Post-Construction Phase

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.

6.3.4                              First-year of Additional CCGT Commissioning

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.

6.3.5                              Maintenance Dredging

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.

6.4                                    Sampling Depths & Replication

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.

6.5                                    Water Quality Compliance

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.

7                                          Waste Management

7.1                                    Introduction

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.

7.2                                    Waste Management Practices

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.

7.3                                    Methodology and Criteria

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:

8                                          Land Contamination

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.

9                                          Ecology

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).

10                                       Fisheries

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.

11                                       Landscape and Visual

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.

12                                       Cultural Heritage

As no impacts to terrestrial and marine cultural heritage resources are expected, no mitigation measure and environmental monitoring is required.

13                                       Health

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.

14                                       Environmental Site Inspection

14.1                                 Site Inspections

Site inspections provide a direct means to assess and confirm that the Contractor(s)¡¦s environmental protection and pollution control measures are in compliance with the contract specifications.  The site inspection 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.

14.2                                 Compliance with Legal & Contractual Requirements

There are contractual environmental protection and pollution control requirements as well as environmental protection and pollution control laws in Hong Kong with which the construction activities will comply.

In order that the works are in compliance with the contractual requirements, the works method statements submitted by the Contractor(s) to 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.

14.3                                 Environmental Complaints

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).

14.4                                 Log-Book

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.
