1                                            Introduction

1.1                                      Purpose of the Manual

This Environmental Monitoring and Audit (EM&A) Manual (“the Manual”) has been prepared by ERM-Hong Kong, Limited (ERM) on behalf of The Hongkong Electric Co Ltd (HEC).  The Manual is a supplementary document of the EIA Study of the project entitled Renewable Energy by a Wind Turbine System on Lamma Island (hereafter referred to as the Project).

The Manual has been prepared with reference to the EIA Study Brief (No. ESB-112/2004) 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 construction and operation.  It provides systematic procedures for monitoring and auditing of potential environmental impacts that may arise from the works.

1.2                                      Project Description

1.2.1                                Background to the Study

The Hongkong Electric Co Ltd (HEC) is committed to providing a high quality power supply to its customers with due care for the environment.  Recognizing the importance of sustainable development, HEC is proposing to install a wind turbine of capacity ranging from 600 to 850kW as a demonstration project to utilize wind energy for renewable power generation on Lamma Island, Hong Kong.

Following the completion of a 12-month wind power monitoring exercise on Lamma Island in November 2002, a wind atlas was developed to assess the wind potential of the Island.  A number of areas were identified as having wind power density over 150W/m2, equivalent to the average wind speed of about 5.5m/s, and generally considered suitable for wind energy utilization.  The existing power supply to Lamma Island is by means of 11kV power lines, high voltage distribution pillar and low voltage distribution cables from HEC’s distribution network.

Following the completion of a site selection exercise the wind turbine has proposed to be located at Tai Ling Tsuen (Figure 1.1).  The output will be connected to the existing power grid for supplying renewable energy to HEC customers.  The operation of the wind turbine will be monitored and controlled through a central monitoring system located in a control room of the Lamma Power Station.  The wind turbine site will be unmanned and will only require attendance of operational personnel during emergency or routine maintenance.

On 23 March 2004, HEC submitted an application (Project Profile No. PP-209/2004) for an EIA Study Brief under Section 5(1) of the Environmental Impact Assessment Ordinance (Cap 499) (EIAO).  The EIA Study Brief (No. ESB-112/2004) was issued on 6 May 2004 under Section 5(7) of the EIAO.

Subsequently, HEC commissioned ERM as the Environmental Consultant to undertake an EIA for this Project.  As part of the Study requirements, this Project specific EM&A Manual has been prepared to provide further details of the specific EM&A requirements that have been recommended during construction and operation of the Project.  In particular, the requirements for ensuring compliance with mitigation measures specified for landscape and visual, noise, dust, water quality and ecological impacts are defined.

1.2.2                                The Project

The Project constitutes a Designated Project by virtue of Item D.1 of Part I of Schedule 2 under the EIAO. 

The works that are the subject of the EIA Study include the construction and operation phases of the Project.  The key components of the Project includes the following:

i.          Erection of a wind turbine (hub height approximately 45m and rotor blade diameter of approximately 52m, overall height of the wind turbine approximately 71m);

ii.        Small-scaled excavation and construction of the wind turbine foundation (affected area approximately 15m by 15m);

iii.      Construction of a site platform and retaining wall (affected area approximately 25 m by 60 m);

iv.      Construction of one stainless steel hut as high voltage distribution pillar (HVDP) (size approximately 4.6 m length, 2.5 m width, 2.8 m height) for housing of switchgear and power conditioning devices.  Transformer will be installed at the bottom of the wind turbine tower;

v.        Underground distribution cables laying for connection to the nearby existing cable route (approximately 50m in length); and

vi.      Operation and maintenance of the wind turbine system.

1.2.3                                Construction Programme

Once the EIA Report has been formally approved by Government, HEC will obtain an Environmental Permit (EP) for construction of the Project.  Once the EP has been obtained the construction of the Project is scheduled to commence in the first quarter of 2005 and will be completed within about 12 months, 8 months for civil works including site preparation, formation and foundation, and 4 months for electrical and mechanical works (such as installation & erection of the wind turbine). 

1.3                                      Objectives of the EM&A Programme

The construction and operational impacts resulting from the implementation of the Project are specified in the EIA Report.  The EIA Report also specifies mitigation measures that need to be implemented to ensure compliance with the required environmental criteria.  These mitigation measures and their implementation requirements are presented in the Implementation Schedule (Annex A).  The EIA recommends that environmental monitoring will be necessary to assess the effectiveness of measures implemented to mitigate potential noise and ecological impacts during operation of the Project.  Regular environmental auditing during construction is also recommended to ensure that potential impacts from other sources are adequately addressed through the implementation of the mitigation measures defined in this EIA Report. 

This Manual provides the EM&A requirements that have been recommended in the EIA Report in order to ensure compliance with the specified mitigation measures.  The main objectives of the EM&A programme are to:

·           provide a database against which any short or long term environmental impacts of the project can be determined; 

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

·           monitor the performance of the project and the effectiveness of mitigation measures;

·           verify the environmental impacts predicted in the EIA Study;

·           determine project compliance with regulatory requirements, standards and government policies;

·           take remedial action if unexpected problems or unacceptable impacts arise; and

·           provide data against which environmental audits may be undertaken.

1.4                                      The Scope of the EM&A Programme

The scope of the EM&A programme is to:

·           implement monitoring inspection and audit requirements for noise monitoring programme;

·           implement monitoring inspection and audit requirements for ecology monitoring programme;

·           implement inspection requirements for mitigation measures;

·           liase with, and provide environmental advice (as requested or when otherwise necessary) to construction site staff on the comprehension and consequences of the environmental audit;

·           identify and resolve environmental issues and other functions as they may arise from the construction works;

·           check and quantify the Contractor's overall environmental performance, and remedial actions taken to mitigate adverse environmental effects as they may arise from the works;

·           conduct monthly reviews of monitored impact data as the basis for assessing compliance with the defined criteria and to ensure that necessary mitigation measures are identified and implemented, and to undertake additional ad hoc monitoring and auditing as required by special circumstances;

·           evaluate and interpret all 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;

·           manage and liase with other individuals or parties concerning other environmental issues deemed to be relevant to the construction process;

·           conduct regular site inspections of a formal or informal nature to assess:

-                 the level of the Contractor's general environmental awareness;

-                 the Contractor's implementation of the recommendations in the EIA;

-                 the Contractor's performance as measured by the EM&A;

-                 the need for specific mitigation measures to be implemented or the continued usage of those previously agreed;

-                 to advise the site staff of any identified potential environmental issues; and

-                 submit 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.

 

1.5                                      Organisation and Structure of the EM&A

1.5.1                                General

The Proponent (HEC) shall appoint an Environmental Team (ET) to conduct the monitoring and auditing works and to provide specialist advice on the undertaking and implementation of environmental responsibilities. 

The ET shall have previous relevant experience with managing similarly sized EM&A programmes, particularly concerning ecological impacts, and the Environmental Team Leader (ET Leader) shall be a recognised environmental professional, preferably with a minimum of seven years relevant experience in impact assessments and impact monitoring programmes.

With the consideration of the reasons listed below, as well asDue to the small-scale nature of the Project and low magnitude of expected impacts, it is not considered necessary to appoint an independent environmental consultants to act as an " Independent Environmental Checker" (IC(E)) to verify and validate the environmental performance of the Contractor and his the Environmental Team appointed by the Proponent:.

·           Low complexity, reliability and implementation experience of the proposed mitigation measures;

·           Low significance, short duration and reversibility of the impacts due to the Project; and

·           No complicated monitoring and auditing exercise and results to validate.

1.5.2                                Project Organisation

·           Section 9 details the EM&A reporting requirements.

The EM&A Manual is an evolving document that should be updated to maintain its relevance as the Project progresses.  The primary focus for these updates will be to ensure the impacts predicted and the recommended mitigation measures remain consistent and appropriate to the manner in which the works are to be carried out.

 

2                                            EM&A GENERAL REQUIREMENT

2.1                                      Introduction

In this section, the general requirements of the EM&A programme are presented with reference to the EIA Study findings that have formed the basis of the scope and content of the programme.

2.2                                      EM&A

Key environmental issues associated with the construction of the Project will be addressed through monitoring and controls specified in the EM&A Manual and construction contract.  Ecology and noise will be subject to EM&A, the details of which are outlined in Sections 3 and 5. 

The monitoring of the effectiveness of the mitigation measures will be achieved through site inspections.  The inspections will include within their scope, mechanisms to review and assess HEC’s environmental performance, ensuring that the recommended mitigation measures have been properly implemented, and that timely resolution of received complaints are managed and controlled in a manner consistent with the recommendations of the EIA Report.

2.2.1                                Environmental Monitoring

Impact and operational monitoring will be carried out by the Environmental Team.  Monitoring work is focussed on ecology, specifically construction phase impacts to the Romer’s Tree Frog and operation phase impacts to birds and to a noise sensitive receiver.  These are discussed in Sections 3 and 5 of this Manual.

2.2.2                                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 (either accidental or through inadequate implementation of mitigation measures on the part of the Contractor) does occur, the cause will be quickly identified and remediated, and the risk of a similar event recurring is reduced. 

2.2.3                                Site Inspections

In addition to monitoring ecology and noise as a means of assessing the ongoing performance of the construction works, the ET Leader shall undertake site inspections and audits of on-site practices and procedures.  The primary objective of the inspection and audit programme will be to assess the effectiveness of the environmental controls established by the construction team(s) and the implementation of the environmental mitigation measures recommended in the EIA Report.

The findings of site inspections and audits shall be made known to the Contractor at the time of the inspection to enable the rapid resolution of identified non-compliances.  Non-compliances, and the corrective actions undertaken, shall also be reported in the monthly EM&A Reports.

Section 8 of this Manual presents details of the scope and frequency of on-site inspections and defines the range of issues that the audit protocols should be designed to address.

2.2.4                                Enquiries, Complaints and Requests for Information

Enquiries, complaints and requests for information can be expected from a wide range of individuals and organisations including members of the public, Government departments, the press and television media and community groups.  During construction of the Project, the majority of such correspondence is likely to be received directly by HEC.

All enquiries concerning the environmental effects of the works, irrespective of how they are received, shall be reported to HEC who shall set up procedures for handling, investigation and storage of such information.  The following steps shall then be followed:

1)        The ET Leader shall notify HEC of the nature of the enquiry.

2)        An investigation shall be initiated to determine the validity of the complaint and to identify the source of the problem.

3)        HEC shall undertake the following steps, as necessary:

·         investigate and identify source of the problem;

·         if considered necessary by HEC, undertake additional monitoring to verify the existence and severity of the alleged complaint;

·         identify necessary remedial measures and implement as soon as possible;

·         repeat the monitoring to verify effectiveness of mitigation measures; and

·         repeat review procedures to identify further possible areas of improvement if the repeat monitoring results continue to substantiate the complaint.

4)        The outcome of the investigation and the action taken shall be documented on a complaint proforma (Annex B).  A formal response to each complaint received shall be prepared by HEC within a maximum of five working days, in order to notify the concerned person(s) that action has been taken.

5)        All enquiries which trigger this process shall be reported in the monthly reports which shall include results of inspections undertaken by the contractor, and details of the measures taken, and additional monitoring results (if deemed necessary).  It should be noted that the receipt of complaint or enquiry will not be, in itself, a sufficient reason to introduce additional mitigation measures. 

In all cases the complainant shall be notified of the findings, and audit procedures shall be put in place to ensure that the problem does not recur.

2.2.5                                Reporting

Monthly reports submitted to HEC, EPD and AFCD shall be prepared by the ET.  The monthly reports shall be prepared and submitted within 10 working days of the end of each reporting month.  Additional details on reporting protocols are presented in Section 9.

2.2.6                                Cessation of EM&A

The ET shall continue to carry out environmental monitoring and site inspections until completion of the construction works and the specified operational phase monitoring period.

 

3                                            Ecology

3.1                                      Introduction

Potential ecological impacts associated with the construction and operation of the wind turbine have been identified in the EIA Report.  The following measures have been developed in accordance with this approach to mitigate the impacts. 

3.2                                      Mitigation Measures

3.2.1                                Measures for Romer’s Tree Frog

Undertake Romer’s Tree Frog surveys within the Project Area just before the construction works commence.  Due to the small size of the Project Area and given that there are no optimal habitats for Romer’s Tree Frog, one day-time and one night-time survey is considered sufficient.  The surveyor(s) should actively search within the Project Area paying special attention to the water bodies (ie abandoned containers).  All recorded Romer’s Tree Frog (adults and tadpoles) must be caught by hand and translocated to the stream pools of middle course of Stream S4 near Lo Tik Wan (Figure 3.1), the critical natural habitats for Romer’s Tree Frog within the Study Area, immediately after the survey.  The Romer’s Tree Frog surveys and translocation works shall be undertaken by a qualified ecologist with at least five years of relevant experience in faunal translocation works.

3.2.2                                Measures for Construction Runoff

Surface run-off from the construction site should be directed into existing stream channel via adequately designed sand/silt removal facilities such as sand traps, silt traps and sediment basins.  Channels, earth bunds or sand bag barriers should be provided on site to properly direct stormwater to such silt removal facilities. 

3.2.3                                Good Construction Practice

·           Erect fences along the boundary of the works area before the commencement of works to prevent tipping, vehicle movements, and encroachment of personnel onto adjacent areas. 

·           Avoid any damage and disturbance, particularly those caused by filling and illegal dumping, to the remaining and surrounding natural stream habitats.

·           Regularly check the work site boundaries to ensure that they are not breached and that no damage occurs to surrounding areas.

·           Prohibit and prevent open fires within the site boundary during construction and provide temporary fire fighting equipment in the Project Area.

·           Treat any damage that may have occurred to individual major trees in the adjacent area and along the 275 kV Cable Route (used to transport the construction materials) with surgery.

·           Reinstate temporary disturbed areas immediately after completion of the construction works, ie through on-site tree/shrub planting.  Tree/shrub species used should make reference from those in the surrounding area and/or Annex C of the EIA Report.

3.3                                      Environmental Monitoring and Audit

3.3.1                                Construction

The implementation of the ecological mitigation measures stated in Section 3.3 above should be checked as part of the environmental monitoring and audit procedures during the construction period. 

3.3.2                                Operation

Monitoring for bird collision during operation is required.  The purpose of the monitoring is to assess the impact (via collisions) of the wind farm on birds, with a particular focus on species of conservation interest (ie Black Kite).  During the operation of the wind turbine, monitoring will be undertaken at monthly intervals for a period of 12 months.  An area of 50 m radius will be searched around the base of the turbine.  After this 12-month period, the monitoring results will be reviewed.  Should any bird mortality or injury be confirmed as due to the wind turbine, relevant government departments (ie Environmental Protection Department (EPD) and Agriculture, Fisheries and Conservation Department (AFCD)) would be notified.  If the bird collision event persists more than 3 times, HEC will discuss remedial action with government and implement any agreed actions to solve the event such as adjustment of wind turbine lighting and the colour of the wind turbine.  The effectiveness of the proposed remedial action will be verified and evaluated with discussion with EPD/AFCD.

A simple Event and Action Plan during the first 12 months of operation of the wind turbine is recommended in Table 3.1.

Bird injury or mortality recorded in the vicinity of the wind turbine (50 m radius from the turbine) and confirmed due to the wind turbine.

1. Notify HEC and check the wind turbine site to find out the cause of the event(s).

1. Identify and report the cause(s) of the event if bird mortality or injury confirmed due to the wind turbine.

 

 

2. Undertake weekly bird monitoring (observing the influence of the wind turbine on the behaviour of birds).  The normal monitoring schedule will be resumed if the cause(s) of the event have been identified.

2. Submit proposals to relevant government departments (ie EPD and AFCD) for remedial action and implement the action to solve the event if the collision event persists more than 3 times.

 

 

3. If the collision event persists more than 3 times, discuss and develop remedial actions with HEC such as adjustment of wind turbine lighting and the colour of the wind turbine.

3. Verify and evaluate the effectiveness of the remedial action with Environmental Team Leader/ Environmental Manager and EPD/AFCD.

If, after the 12-months monitoring period, insignificant number of bird collisions have been reported then monitoring will cease as it will have been demonstrated that the wind turbine is not having an adverse impact on bird species.

 

4                                            Dust

4.1                                      Introduction

For land based construction works, dust suppression measures have been recommended in the EIA Report to reduce potential impacts to sensitive receivers.  Implementation of these measures shall be reviewed during site inspections to ensure compliance with the requirements of the EIA and the effectiveness of these measures.

4.2                                      Dust Generating Activities

Site formation by cutting the hill slope and filling to form the site platform, foundation construction, cable laying, wind turbine erection and landscaping works are the main construction activities.  In them, wind erosion, materials handling and on-site stockpiling are the major dusty activities.

4.3                                      Sensitive Receivers

ASRs have been identified within 500 m from the project site in accordance with the EIA Study Brief (ESB-112/2004) and the criteria set out in Annex 12 of the EIAO-TM and through site inspections and review of land use plans.  Type of Use, height of buildings, their horizontal distance from the worksite boundary and approximate base elevation (in mPD) are summarised in Table 4.1.  The locations of ASRs are shown in Figure 4.1.

4.4                                      Dust Mitigation Measures

In order to reduce the dust emissions during construction phase, the following dust suppression measures stipulated in the Air Pollution Control (Construction Dust) Regulation will be incorporated into the Particular Specification and implemented by the Contractor.

·           Covering entirely by impervious sheet or frequently watering of the on-site stockpile of excavated materials to keep wet always before backfilling;

·           Frequent watering of exposed area or worksite of excavation to maintain surface wet;

·           Provision of vehicle washing to remove any dusting materials from small village trucks’ body and wheel at the exit of worksite;

·           Well-maintained diesel-powered mechanical equipment to avoid black smoke emissions; and

·           Shut-down of diesel-powered mechanical equipment or trucks inside the worksites when they are not in operation.

4.5                                      Environmental Monitoring & Audit

Given the very limited dust emission anticipated due to the small worksites and limited generation of excavated spoils, dust monitoring is not required during the construction stage.  Weekly site audit shall be conducted instead, to ensure the recommended dust suppression measures are properly implemented.

5.1                                      Introduction

In this section, the general requirements, methodology, equipment, and mitigation measures for the monitoring and audit of noise impacts associated with the construction and operation of the Project are described below.

5.2                                      Noise Generating Activities

5.2.1                                Construction Phase

The use of PME during the construction phase will be the main source of noise impact.  The main construction activities are:

·           excavation by cutting and filling to form a site platform;

·           construction of retaining wall around site perimeter;

·           construction of concrete footing for wind turbine foundation;

·           erection of wind turbine and high voltage distribution pillar; and

·           landscaping works including planting of trees and shrubs.

5.2.2                                Operational Phase

The sources of noise emitted from the operating wind turbine include the rotation of mechanical and electrical equipment and aerodynamic noise originating from the flow of air around the blade. 

5.3                                      Noise Sensitive Receivers

All NSRs, as defined by EIAO-TM, have been identified within an area of 300 m of the Study Area boundary.  For NSRs outside the 300m Study Area boundary, such as Tai Wan Kau Tsuen and Lo Tik Wan are also identified.Noise Sensitive Receivers (NSRs) as defined by the EIAO-TM have been identified within an area of 500 m of the Study Area boundary.  Their approximate horizontal distances from the proposed site boundary are presented in Table 5.1 and  Tthe locations of the NSRs have been shown in Figure 5.1.  No planned NSRs are identified in the study boundary.

5.4.1                                Methodology and Criteria

Construction Phase

As the predicted construction noise levels at the identified NSRs comply with the stipulated noise criterion, noise monitoring is not required during the construction stage.  Methodology and criteria related to EM&A is therefore not applicable for the construction phase.

Operational Phase

The EIAO-TM and Technical Memorandum on Noise From Places Other than Domestic Premises, Public Places or Construction Sites (IND-TM) specifies the applicable Acceptable Noise Levels (ANLs) for operational noise of wind turbine system.  The ANLs are dependent on the Area Sensitivity Rating (ASR) and the time of the day and are presented in Table 5.2.

Fixed Plant Noise

Noise associated with the operation of wind turbine is controlled under Section 13 of the NCO and the predictions will be undertaken in accordance with the IND-TM.  The criteria noise limits are set out in the EIAO-TM as follows:

·           the total fixed source noise level at the facade of the nearest NSR is at least 5 dB(A) lower than the appropriate ANL (as shown in Table 5.4) as specified in the Technical Memorandum on Noise from Places other than Domestic Premises, Public Places or Construction Sites (IND-TM); or,

·           where the prevailing noise level in the area is 5 dB(A) or more below the appropriate ANL, the total fixed source noise level must not exceed this noise level. 

The criteria noise limits stipulated in the IND-TM are dependent on the Area Sensitivity Rating (ASR) of the NSRs as shown in Table 5.24.

As the site is located in a rural area and no influencing factors affect the NSRs, an ASR “A” has been assumed for the NSRs located within 300 m of study boundary.  Background noise measurements have been conducted by HEC during 2004 to investigate the prevailing noise level in the study area.  The 48-hour continuous measurements of prevailing free field noise levels in the vicinity of No. 1 Tai Ling Tsuen are in the range of 45 – 80 dB(A) LAeq, 30min.  With the inclusion of façade correction, the measured prevailing noise level will be higher than the (ANL-5) criterion, and therefore the (ANL – 5) criterion, i.e. 45 dB(A) LAeq, 30min for night-time period will be considered as the stipulated noise limit for the assessment of operational noise impact.

In any event, the Area Sensitive Rating assumed in this Report is for indicative assessment only given that there are currently no influencing factors assumed in the vicinity of the NSRs.  It should be noted that fixed noise sources are controlled under Section 13 of the NCO.  At the time of investigation, the Noise Control Authority shall determine noise impact from concerned fixed noise sources on the basis of prevailing legislation and practices being in force, and taking account of contemporary conditions / situations of adjoining land uses.  Nothing in this Report shall bind the Noise Control Authority in the context of law enforcement against all the fixed noise sources being assessment. As the site is located in a rural area and no influencing factors affect the NSRs, an ASR “A” has been assigned to the NSRs located within 300 m of study boundary.  Background noise measurements have been conducted by HEC during 2004 to investigate the prevailing noise level in the study area.  The 48-hour continuous measurements of prevailing free field noise levels in the vicinity of No. 1 Tai Ling Tsuen are in the range of 45 – 80 dB(A) LAeq, 30min.  With the inclusion of façade correction, the measured prevailing noise level will be higher than the (ANL-5) criterion, and therefore the (ANL – 5) criterion, i.e. 45 dB(A) LAeq, 30min for night-time period will be considered as the stipulated noise limit for the assessment of operational phase. 

5.4.2                                Monitoring Equipment

The ET Leader shall be responsible for providing and maintaining a sufficient number of sound level meters to conduct the necessary impact monitoring and ad hoc monitoring at the agreed monitoring location.

Sound level meters and calibrators shall comply with the International Electrotechnical Commission (IEC) Publication 651 : 1979 (Type 1) and 804 : 1985 (Type 1) specification as referred to in the GW-TM & IND-TM.  The sound level meters shall be supplied and used with the manufacturers recommended wind shield and with a tripod.

The calibration of the sound level meters shall be carried out in accordance with the manufacturer's requirements.  The sound level meters, including the calibrators, shall be verified by the manufacturers once every two years to ensure that they perform to the same level of accuracy as stated in the manufacturers specifications.  Calibrated hand-held anemometers capable of measuring the wind speed in ms-1 shall also be supplied for the measurement of wind speeds during noise monitoring periods. The anemometers shall be used and calibrated in accordance with the manufactures recommendations.

Sound level meters shall be calibrated using a portable calibrator before and after each measurement.  The calibration levels shall be noted with the measurement results and where the difference between the calibration levels is greater than 1 dB(A) the measurement shall be repeated.

The ET Leader shall ensure the equipment shall be kept in a good state of repair in accordance with the manufacturer's recommendations and maintained in proper working order with sufficient spare equipment available in the event of breakdown to maintain the planned monitoring programme.

Noise measurements should not be made in the presence of fog, rain, wind with a steady speed exceeding 5 ms-1 or wind with gusts exceeding 10 ms-1.  The wind speed shall be checked with the hand-held anemometers.

5.4.3                                Monitoring Location

The ET Leader will be responsible for conducting noise monitoring at the following representative monitoring location, as defined in Table 5.3 and shown in Figure 5.2.

Table 5.3         EM&A Representative Monitoring Location

NSR No.

Identity/Description

NM1

No. 1 Tai Ling Tsuen (N1)

The monitoring location shall normally be at a point 1 m from the exterior of the sensitive receiver building façade and at a height approximately 1.2 m above the ground or at the height that has the least obstructed view of the construction activity in relation to the receiver.  For reference, a correction of +3 dB(A) shall be made to the free field measurements. 

5.4.4                                Baseline Monitoring

To investigate the prevailing noise levels at the nearest NSR (NM1) , a continuous 48-hour noise measurement has been conducted from 1200 hours on 25 May 2004 to 1200 hours on 27 May 2004.  As there were problems in gaining access to the nearest NSR (NM1), free-field noise measurement has been made at a close proximity to NM1.  In addition, as the measurements are conducted off-site from the nearest NSR NM1, potential community noise associated with the residents will not be included in the measurement.  Therefore, the measured levels are considered to represent the lowest ambient noise levels. 

The chirps of the insect “cicadas” were identified as the dominant noise sources during the noise measurement.  Although the chirps are seasonal in nature, the cicadas only chirps in early morning and day-time, such that the measured noise levels during night-time would not be affected by the chirps.  Therefore the background noise measurement would represent the typical acoustic environment in the vicinity of the NSRs.  The noise measurement results with facade correction are summarised in Table 5.4.  A timeline chart showing the prevailing noise levels is presented in Figure 5.3.

Without potential noise sources in the vicinity of the nearest NSR, it is anticipated that the measured prevailing noise levels can represent the results of baseline monitoring, and hence baseline monitoring is not necessary.

5.4.5                                Impact Monitoring

Construction Phase

Given that compliance with the stipulated noise criterion is predicted, noise monitoring is not required during the construction stage.  Weekly site audits will be conducted to ensure that the plant inventory used on site are consistent with the assumptions and mitigation measures used in the EIA report.

 


Operational Phase

During the operation of the wind turbine, noise monitoring shall be carried out during the night-time period at the agreed monitoring location once every fourteen days for a period of six consecutive months.  A sample data sheet is shown in Annex C.  Two types of measurement shall be carried out:

a)    Broadband measurement of LAeq (t).  Note that the measurement period (t) shall normally be 30 minutes (six consecutive 5-minute measurement).  However, if it can be demonstrated that the noise level is constant, then a shorter measurement period (no less than 5 minutes) may be used.

b)    Frequency analysis between 31.5 and 16 kHz measured at 1/3 octave intervals.  If the noise emanating from the wind turbine is found to be tonal (as defined in IND-TM) then an appropriate tonal correction should be applied to the measured noise level (MNL) to achieve the corrected noise level (CNL).  This CNL shall be compared with the noise specifications.

5.4.6                                Mitigation Measures

Construction Phase

Though the predicted construction noise levels comply with the stipulated noise criterion, good site practice and noise management is recommended for minimising the construction noise impact on nearby NSRs.  The measures include:

·           Only well-maintained plant should be operated on-site and plant should be serviced regularly during the construction works;

·           Machines and plant that may be used intermittently, such as vibratory poker, should be shut down between work periods or should be throttled down to a minimum;

·           Plant known to emit noise strongly in one direction, should, where possible, be orientated to direct noise away from nearby NSRs; and

·           Mobile plant should be sited as far away from NSRs as possible.

 

In the event of exceedances or complaints, upon the advice of the ET Leader, the Contractor shall liaise with the ET Leader to agree further mitigation measures, propose the recommended measures to HEC for approval, and then implement the mitigation measures.

Operational Phase

 

In the design stage, the allowable maximum sound power level of 100dB(A) with no pure tones shall be included in the tender specification of wind turbine.the maximum allowable sound power level of 100 dB(A) shall be included in the tender specification of wind turbine.   

 

The supplier shall guarantee this noise level by providing certificate of measurement and verify the overall noise level during commissioning and testing in accordance to international standard procedures such as IEC 61400-11.  Whenever necessary, the supplier shall apply attenuation measures to achieve the guaranteed noise level during detailed design stage.

 

During the operational phase of the wind turbine, in the event of exceedances, HEC shall liaise with the ET Leader to investigate the cause of noise exceedances taking into account background noise levels.  Whenever necessary, the supplier of the wind turbine will be requested to provide attenuation measures to achieve the guaranteed noise level during detailed design stage.

 

6                                            Water Quality

6.1                                      Introduction

This section presents the EM&A recommendations for auditing the water quality mitigation measures during the construction phase of the Project.

6.2                                      Construction Phase

As stated in the EIA report, no water quality monitoring is required for the construction phase.  However, as part of the regular audit procedures, it is recommended that the ET Leader confirms that the Contractor has implemented the mitigation measures, as described in Section 8.6 of the EIA Report. 

6.2.1                                Mitigation Measures

The Contractor shall implement the following on-site measures to minimise potential water quality impacts associated with land based construction.

Surface Run-off

·           Surface run-off from the construction site should be directed into stream channel via adequately designed sand/silt removal facilities such as sand traps, silt traps and sediment basins.  Channels, earth bunds or sand bag barriers should be provided on site to properly direct stormwater to such silt removal facilities. 

·           Silt removal facilities should be maintained and the deposited silt and grit should be removed regularly, at the onset of and after each rainstorm to ensure that these facilities are functioning properly at all times.

·           During excavation in the wet season, temporarily exposed soil surfaces should be covered, eg by tarpaulin, and temporary access roads should be protected by crushed stone or gravel, as excavation proceeds.  Intercepting channels should be provided (eg along the crest/edge of the excavation) to prevent storm runoff from washing across exposed soil surfaces.  Arrangements should always be in place to ensure that adequate surface protection measures can be safely carried out well before the arrival of a rainstorm.

·           Earthworks final surfaces should be well compacted and the subsequent permanent work or surface protection should be carried out as soon as practical after the final surface are formed to prevent erosion caused by rainstorms.  Rainwater pumped out from trenches or foundation excavations should be discharged into storm drains via silt removal facilities.

·           Open stockpiles of construction materials (eg aggregates and sand) on site should be covered with tarpaulin similar fabric during rainstorms.  Measures should be taken to prevent the washing away of construction materials, soil, silt or debris into any drainage system.

Wastewater from Site Facilities

·           The use of chemical toilets will be necessary and these should be provided by a licensed contractor, who will be responsible for appropriate disposal and maintenance of these facilities.

In addition to implementing the specified mitigation measures, the Contractor will also be required to obtain a WPCO discharge licence should any wastewater discharges be released from the site.  This may require the Contractor to undertake monitoring of the quality/quantity of the discharges to show compliance with the conditions of the licence; however, at this stage, this does not form part of the EM&A programme.

6.2.2                                Operation Phase

No monitoring of water quality or mitigation measures are required during the operational phase of the Project.

 

7                                            Waste Management

The construction works will involve some site formation which will necessitate the removal of small quantities of spoil (approximately 1,300 m3 of excavated materials).  The quantity of waste materials arising from the construction phase is not expected to be high as most of the spoil (95% of the excavated materials) will be used as backfill, but practical measures will be taken to avoid, minimise and recycle wastes.  Good construction practices, including limiting activities within the site boundary and avoiding of filling and illegal dumping by site management and audit, and provision of impermeable floor for the site are recommended to ensure that adverse environmental impacts are prevented.

During the construction phase, weekly site audit shall be conducted to ensure the good construction practice, waste management and disposal are properly implemented.

 

8                                            Landscape Visual

8.1                                      General

Details of all mitigation measures should be further developed at the detail design stage.  The recommended mitigation measures should be included into the Contract Document where the Contractor is responsible for their implementation as recommended in the EIA Study.  During the site environmental audit inspections, the Environmental Team (ET) Leader should be responsible for ensuring that landscape and visual mitigation measures are fully implemented by the Contractor, as per the approved construction programme. The following key mitigation measures are recommended.Details of all mitigation measures should be further developed at the detail design stage.  The recommended mitigation measures should be included into the Contract Document where the Contractor is responsible for their implementation as recommended in the EIA Study.  During the site environmental audit inspections, the Environmental Team (ET) Leader should be responsible for ensuring that landscape and visual mitigation measures are fully implemented by the Contractor, as per the approved construction programme.

New cut and fill slopes and other land affected by construction works would be reinstated to natural land form and topography of the natural slope as far as practical. Grading of these slopes to resemble a natural, rolling landform similar to that of adjacent topography would be carried out. Approximately 1,400 sq.m. of disturbed areas would be reinstated.

MM2

Appropriate landscape planting including trees, shrubs and grasses (approx. 1,400 sq.m.) will be provided to soften the ground level appearance of the proposed wind turbine site.

MM3

A light grey non-reflective colour scheme will be used to enable the proposed wind turbine to blend in well with natural surroundings and minimize the visual intrusion.

MM4

Existing soil resources on site from the cut slope will be re-used for backfilling at site as far as practicable to minimize the need to import or export soils.

MM5

Selection of low rotating speed machine to minimize the visual disturbance.

·                                      Appropriate colour scheme and non-reflective paints should be made to enable the proposed wind turbine to blend in well with natural surroundings and minimise the visual intrusion;

·                                      The shape of the maintenance platform should be adjusted so that the site formation works could be planned to avoid disturbance to the existing two trees within the site; and

·                                      In order to minimize the visual disturbance, a low rotating speed machine should be chosen.

8.3                                      Construction Stage

Mitigation measures recommended in the EIA Report for landscape and visual impacts during the construction stage are the same as those in the construction stage and these would be implemented by the contractor.

Mitigation measures recommended in the EIA Report for landscape and visual impacts during the construction stage are summarised below:

·                                      New cut and fill slopes and other land affected by construction works should be reinstated to natural land form and topography of the natural slope as far as practical;

·                                      Appropriate compensatory planting including trees, shrubs and grasses should be provided within the project site;

·                                      Screening of site construction works by use of temporary hoarding that is appropriate to its site context;

·                                      Tree protective measures should be implemented to ensure trees identified as to be retained are satisfactorily protected during the construction phases; and

·                                      Conservation of soil resources for reuse.

8.4                                      Operation Stage

A landscape architect should make regular on-site visits within the establishment period to monitor the condition of newly planted vegetation.  

A landscape architect should make regular on-site visits within the establishment period to monitor the condition of newly planted vegetation before handling over the responsibility of maintenance to the Hongkong Electric Co., Ltd.

 

9                                            Site Environmental Audit

9.1                                      Site Inspection

Site inspections provide a direct means to track and ensure the enforcement of specified environmental protection and pollution control measures.  The inspections should be undertaken weekly by the Environmental Team (ET) Leader to ensure that appropriate environmental protection and pollution control mitigation measures are properly implemented.  Additionally, the ET Leader shall be responsible for defining the scope of the inspections, detailing any deficiencies that are identified, and reporting any necessary action or mitigation measures that were implemented as a result of the inspection; the results of the inspections shall be made available to HEC. 

The areas of inspection should include the general environmental conditions in the vicinity of the site and pollution control and mitigation measures within the site; it should also review the environmental conditions outside the site area which are likely to be affected, directly or indirectly, by site activities.  The ET Leader shall make reference to the following information in conducting the inspections:

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

·           ongoing results of the EM&A programme;

·           works progress and programme;

·           individual works method statements which shall include proposals on associated pollution control measures;

·           the contract specifications on environmental protection; and

·           the relevant environmental protection and pollution control laws.

The ET Leader’s inspection results and their associated recommendations on improvements to the environmental protection and pollution control works shall be submitted to HEC within 24 hours, for reference and for taking immediate action.  They shall also be presented, along with the remedial actions taken, in the monthly EM&A report.  HEC and their contractors shall follow the procedures and time-frames stipulated in the environmental site inspection for the implementation of mitigation proposals and the resolution of deficiencies in the Environmental Management system.  An action reporting system shall be formulated and implemented to report on any remedial measures implemented subsequent to the site inspections.

 

Ad hoc site inspections shall also be carried out by the ET Leader if significant environmental problems are identified.  Inspections may also be required subsequent to receipt of an environmental complaint, or as part of the associated investigation work.

9.2                                      Compliance with Legal and Contractual Requirements

There shall be contractual environmental protection and pollution control requirements as well as Hong Kong’s environmental protection and pollution control laws which HEC shall comply with.

The ET Leader shall review the progress and programme of the works to check that relevant environmental laws have not been violated, and that any foreseeable potential for violating the laws can be prevented.

HEC shall also regularly copy relevant documents to the ET Leader so that the checking work can be carried out.  The relevant documents are expected to include the updated Work Progress Reports, the updated Works Programme, the application letters for different licences/permits under the environmental protection laws, and all the valid licences/permit.  The site diary shall also be available, upon request, to the ET Leader during his site inspection.

After reviewing the documentation, the ET Leader shall advise HEC of any non-compliance with the contractual and legislative requirements on environmental protection and pollution control for them to take follow-up actions.  If the ET Leader's review concludes that the current status on licence/permit application and any environmental protection and pollution control preparation works is incompatible with the works programme or may result in potential violation of environmental protection and pollution control requirements by the works in due course, he shall also advise HEC accordingly.

Upon receipt of the advice, HEC shall undertake immediate action to remedy the situation.
