1.3 Project Description

1.3.1 Project Background

GT2, GT3, GT4, GT57 and GT6, with a total power generation capacity of 845MW, are located within the Gas Turbine Compound (GT Compound) of LPS. These units have been in operation since 1989 and are approaching the end of their service life. Therefore, HK Electric proposes to decommission and demolish these units sequentially from 2022 onwards, and to construct and commission up to four new OCGTs with a capacity of up to 130 MW each (i.e. the proposed GT8, GT9, GT10 and GT11, with a total power generation capacity of 520 MW) within the GT Compound. These proposed new OCGTs serve to take over the function of the aforementioned existing units in providing additional power generation during peak-lopping and maintaining back-up power supply in case of emergency situations for the continuous operation of the LPS.

1.3.2 Project Scope and Location

The scope of the Project involves the decommissioning/ demolition of the existing units and auxiliary equipment, and subsequent construction and operation of the proposed new OCGTs within the GT Compound. Key project activities are summarised below:

§ Decommissioning and demolition of existing OCGTs/Combined Cycle Gas Turbine (CCGT) (i.e. GT2, GT3, GT4, GT57 and GT6), the black start gas turbine (BSGT) and the adjacent miscellaneous storage shed, and the lube oil storage tank near GT5;

§ Construction of the new GT8, GT9, GT10 and GT11, and installation of the new BSGT and Battery Energy Storage System (BESS);

§ Construction of new cable trenches and the new staircase and lift, and reconstruction of the GT57 Auxiliary Building (GTAB) to a new 132kV Switching Station; and

§ Operation of the new GT8, GT9, GT10 and GT11.

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):

§ Demolition of four existing OCGTs and one existing CCGT at LPS (Schedule 2, Part II, Item 4 A public utility --- electricity power plant); and

§ Installation of up to four new OCGTs at LPS (Schedule 2, Part I, Item D.1 Public utility electricity power plant).

1.4 Objective of the EM&A

The broad objective of this Manual is to define the procedures of the EM&A programme for evaluating the environmental performance of the Project during design, decommissioning/ demolition, construction and operation phases. The decommissioning/ demolition, construction and operational impacts arising from the implementation of the Project are described in the EIA Report. The EIA Report has also recommended mitigation measures and good construction practices to avoid or minimise the potential environmental impacts associated with the Project and comply with the appropriate environmental criteria. These mitigation measures and their implementation requirements are presented in the Implementation Schedule of Mitigation Measures (Appendix A).

The main objectives of the EM&A programme are to:

§ provide a database of environmental parameters against which to determine any short-term or long-term environmental impacts;

§ provide an early indication should any of the environmental control measures or practices fail to achieve the acceptable standards;

§ confirm that the mitigation measures recommended in the EIA Report are properly included in the design of the Project;

§ clarify and identify potential sources of pollution, impact and nuisance arising from the works for the responsible parties;

§ confirm compliance with regulatory requirements, contract specifications and EIA study recommendations;

§ 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);

§ monitor performance of the mitigation measures and to assess their effectiveness;

§ take remedial action(s) if unexpected issues or unacceptable impacts arise;

§ verify the environmental impacts predicted in the EIA; and

§ audit environmental performance.

This EM&A Manual is a working document which will be reviewed periodically and updated if necessary during the implementation of the Project.

1.5 Scope of the EM&A Programme

The scope of this EM&A programme is to:

§ implement inspection and audit requirements for waste management;

The EIA study concluded that no adverse noise impact is anticipated during the decommissioning/ demolition and construction of the Project, and thus noise monitoring is considered not necessary. However, it is recommended to conduct regular environmental site inspections, i.e. on weekly basis, to confirm the implementation of the good site practices as recommended in Section 4.7.1 of the EIA Report throughout the decommissioning/ demolition and construction phases of the Project. These good site practices are also summarised in the Implementation Schedule provided in Appendix A.

3.2 Operation Phase

The EIA study concluded that no adverse noise impact is anticipated during the operation of the Project. EM&A during operation phase of the Project is considered not necessary.

4. Water Quality

4.1 Decommissioning/ Demolition and Construction Phases

The EIA study concluded that no adverse water quality impact is anticipated during the decommissioning/ demolition and construction of the Project, and thus water quality monitoring is considered not necessary. However, it is recommended to conduct regular environmental site inspections, i.e. on a weekly basis, to confirm the implementation of the water quality mitigation measures and good site practices as recommended in Section 5.5 of the EIA Report throughout the decommissioning/ demolition and construction phases. These measures are also summarised in the Implementation Schedule provided in Appendix A.

4.2 Operation Phase

The EIA study concluded that there will be no adverse water quality impact associated with the operation of the Project. EM&A during the operation phase of the Project is considered not necessary.

5. Waste Management

5.1 Decommissioning/ Demolition and Construction Phases

5.1.1 Introduction

The decommissioning/ demolition and construction of the Project are expected to generate the following types of waste:

§ Excavated materials;

§ Construction & demolition (C&D) materials;

§ Chemical waste; and

§ 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 decommissioning/ demolition and construction of the Project.

Waste management will be the Contractor(s)’s responsibility and wastes produced during the decommissioning/ demolition and construction phases 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 decommissioning/ demolition and construction are not disposed of into the surrounding storm drains. The Contractor(s) will be responsible for the implementation of any mitigation measures to reduce waste or redress issues arising from the waste materials.

5.1.2 Waste Management Practices

The waste management practices and recommended mitigation measures will be incorporated into a Waste Management Plan (WMP) as stated in the Practice Notes for Authorised Persons, Registered Structural Engineers and Registered Geotechnical Engineers (PNAP) ADV-19 Construction and Demolition waste for the Project for managing the different types of wastes by the Contractor(s) on site. The WMP will become a part of the Environmental Management Plan (EMP). The Contractor(s) is/ are required to prepare the EMP and submit it to the Project Proponent for approval and then implement the EMP accordingly.

The WMP shall describe the arrangements for avoidance, reuse, recovery and recycling, handling, collection, transport, the estimated rate of C&D materials generation and disposal, and the recommended mitigation measures on waste management as set out in Section 6.5 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 Contractor(s) shall ensure all necessary waste disposal permits or licences are obtained prior to the commencement of the decommissioning/ demolition and construction works. The Contractor(s) shall also open a billing account with EPD in accordance with the Waste Disposal (Charges for Disposal of Construction Waste) Regulation.

The Implementation Schedule (Appendix A) provides details on the appropriate mitigation measures for avoiding and preventing adverse environmental impacts associated with C&D materials, chemical wastes, general refuse and sewage from the workforce. The WMP will be regularly reviewed, and updated as appropriate, throughout the course of the decommissioning/ demolition and 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.

5.1.3 Methodology and Criteria

The Contractor(s) must confirm that the necessary disposal permits or licences are obtained from appropriate authorities in accordance with the various Ordinances. In addition to the regular 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 Appendix A of this Manual, and defined below:

6. Land Contamination

6.1 Decommissioning/ Demolition and Construction Phases

The EIA study has recommended to conduct site investigation and sampling at five hotspot locations (i.e. 4 boreholes and 1 trial pit) to assess the potential land contamination impacts within the Project site in accordance with the Contaminated Assessment Plan (CAP). As the Project site area is still in active operation, the proposed sampling locations are not accessible during the course of the EIA study. Site investigation and soil and groundwater sampling will be undertaken in accordance with the CAP under the supervision of a Land Contamination Specialist when the proposed sampling locations are made available after the demolition of the existing units and structures.

A Land Contamination Specialist shall also be engaged to oversee the removal/ demolition process of the Project and review the need to include additional sampling locations, as per recommendations in the CAP.

During the decommissioning/ demolition and construction phases, good housekeeping practices shall be maintained by the Contractor(s) to minimise the risk of land contamination associated with the decommissioning, demolition and construction activities, including but not limited to the following:

§ Minimise the chemical stock within the Project site, only store the amount of chemicals needed;

§ 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;

§ Provision of impermeable lining or absorbent materials to contain leaks;

§ Provision of spill control materials and equipment;

§ Regular visual inspections to detect any early signs of fuel leakage prior to demolition;

§ Conduct regular maintenance and inspection on plants and equipment, particularly those involve the use of fuel, hydraulic oil or any sort of chemicals; and

§ Divert rainfall and surface run-off around construction areas.

To ensure that these recommendations are properly implemented by the Contractor(s), weekly site inspections during decommissioning/ demolition and construction phases of Project shall be conducted. The visual inspections/audits will look at all aspects of construction activities that disturb soil. The recommended good housekeeping practices for decommissioning/ demolition and construction phases are summarised in the Implementation Schedule provided in Appendix A.

6.2 Operation Phase

Monitoring or audit related to land contamination during the operation phase is considered not necessary.

7. Environmental Site Inspection

7.1 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 decommissioning/ demolition and construction phases of the Project 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 week. 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:

§ the EIA and EM&A recommendations on environmental protection and pollution control mitigation measures;

§ ongoing results of the EM&A programme;

§ work progress and programme;

§ individual works methodology proposals;

§ the contract specifications on environmental protection;

§ the relevant environmental protection and pollution control laws; and

§ previous site inspection results.

The Contractor(s) 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, HK Electric and the Contractor(s) in two working days. 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, HK Electric 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. 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.

7.2 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 decommissioning/ demolition and construction activities will comply.

In order that the works are in compliance with the contractual requirements, the works method statements (where relevant to environmental measures) submitted by the Contractor(s) to HK Electric for approval should 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 HK Electric and the Contractor(s) of any non-compliance from the contractual and legislative requirements on environmental protection and pollution control for follow-up actions.

Upon receipt of the advice, the Contractor(s) will undertake immediate action to remedy the situation. The ET will follow up to confirm that appropriate action will be taken by the Contractor(s) in order to satisfy the environmental protection and pollution control requirements.

7.3 Environmental Complaints

The ET will undertake the following procedures (see Figure 7.1) 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 HK Electric 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), HK Electric 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) undertake additional monitoring (if required) and audit to verify the situation if necessary and confirm that any valid reason for complaint does not recur;

(7) if the complaint is referred by 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;

(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 HK Electric 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. HK Electric will approve the proposed mitigation measures and the ET and IEC will check that the measures have been carried out by the Contractor(s).

7.4 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.
