14                CONCLUSION

14.1          Introduction

The Project is a designated project in accordance with Item C.5 of Part I of Schedule 2 of the EIAO, which specifies “A typhoon shelter designed to provide moorings for not less than 30 vessels”.

14.1.1     This EIA Report has provided an assessment of the potential environmental impacts associated with the construction and operation of the Project, with the consideration of the potential cumulative impact from other projects including the Central Reclamation Phase III (CRIII) and Hong Kong Convention and Exhibition Centre Atrium Link Extension projects. Since the details of the potential future railway projects, i.e. Shatin to Central Link (SCL) and North Hong Kong Island Line (NIL) were not available at the time of this EIA study, the cumulative impacts from these two railway projects could not be addressed. Specific mitigation measures requirements for the Project, as well as an environmental monitoring and auditing programme, have been developed during the assessment of the proposed developments.  The Implementation Schedule of the recommendations is presented in Section 13.  A summary of the environmental impacts associated with the Project are present in Table 14.1. The key assessment assumptions, limitation of assessment methodologies and all obtained relevant prior agreements with the EPD or other authorities on individual environmental media assessment components are given in Appendix 15.1. The key environmental outcomes arising from the EIA study and the principal findings of the study are summarized in Section 14.2.

Water Quality

 

 

 

 

 

 

The major issues would be the potential SS elevations in the water column during dredging for construction of the TBW.  The TBW may also affect the dispersion pattern of the sediment plume potentially generated from dredging under other WDII works including those within the existing CBTS during construction of the CWB tunnel.

All water sensitivity receivers in Victoria Harbour, Western Buffer and Eastern Buffer WCZs

The model results indicate exceedances of WSD water quality (SS) criterion for flushing water intakes (at Kennedy Town, Kowloon South, Quarry Bay, Sai Wan Ho, Sheung Wan, Tai Wan and Wan Chai) and target SS level (at Admiralty Centre and MTRC cooling water intakes). 

WSD water quality criterion for SS: < 10 mg/l

Target SS level at Admiralty Centre and MTRC cooling water intakes: < 40 mg/l

Sedimentation rate at corals: <100g/m2/day

Maximum SS levels predicted at the WSD flushing water intakes ranged from 12.5 mg/l to 51.1 mg/l.

Maximum SS levels predicted at Admiralty Centre and MTRC cooling water intakes ranged from 40.4 mg/l to 100.8 mg/l.

No exceedance for the sedimentation rate was predicted

Restriction on the maximum dredging rates at the sewage pipelines zone, water mains zone, TWB, HKCEC Stage 1 & 3 as well as the western seawall of WCR1 which is close to the WSD intake at Wan Chai;

Deployment of silt curtains around seawall dredging and seawall trench filling in NPR, TCBR, WCR and HKCEC areas.

Deployment of silt screens at selected seawater intakes

Nil

Full compliance with the assessment criterion for sedimentation rate

 

Change of dispersion capacity for polluted storm  water in the existing embayment of CBTS after the placement of the TBW

Cooling water intakes inside the existing CBTS

The TBW operation would not cause unacceptable impacts in the existing embayment of CBTS

Relevant WQO for marine water:

Some local exceedances of the TIN and UIA levels are predicted at the CBTS.  However, these exceedances were not contributed by the Project as similar degree of exceedances was also predicted under the pre-construction scenario.  The associated water quality impact is anticipated to be limited as CBTS has low marine ecological value and the plume of UIA would be confined within the typhoon shelter.

No mitigation measures are considered necessary.

14.2          Environmental Outcomes

14.2.1      The major environmentally sensitive areas within the study area include residential buildings, commercial buildings, hotels, recreational areas, educational institutions, and WSD flushing water intakes and cooling water intakes at the waterfront of Victoria Harbour. With the implementation of the proposed control and mitigation measures, the air, noise and water quality sensitive receivers within the study area would be protected from adverse environmental impacts arising from the Project during both construction and operational phases.  A summary of the key environmental outcomes arising from the EIA study and environmental benefits of the environmental protection measures recommended are presented in Table 14.2 below.

 

           Table 14.2       Summary of Key Environmental Outcomes/ Benefits

 

Issue

Environmental Outcomes/Benefits

 

The Project

Requirements:

The construction of the Trunk Road tunnel beneath the existing CBTS will temporarily affect the existing moorings.  To maintain the operation of the CBTS during the construction period, it is necessary to reprovision a temporary typhoon shelter in the vicinity of the existing one.

 

 

Benefits:   

The temporary reprovisioning of the affected CBTS to the temporary typhoon shelter at the north of the existing one maintains the current provision of mooring area at Causeway Bay area.

 

 

Potential consequences without the Project:

Should the temporary typhoon shelter not be temporarily reprovisioned, the existing mooring area at the CBTS will be temporarily lost during construction of the Trunk Road.

In environmental terms, water quality at Victoria Harbour would be similar for both the situations with and without the Project.

 

Development Alternatives

As alternative to temporarily reprovisioning the typhoon shelter to the north of the existing one, which is the nearby available location, affected vessels sheltered at CBTS could be temporarily relocated to other off-site typhoon shelters. These are very far away from the Causeway Bay area.  In view of the inconvenience to CBTS users and the lack of spare mooring space at other off-site typhoon shelters, this alternative option will have serious impacts to the current users and will receive strong objections.  On site like-for-like temporary reprovisioning of the typhoon shelter at the north of the existing one is recommended in lieu of off-site reprovisioning.

 

Construction Air Quality Impact

Environmental benefits of environmental protection measures recommended:

Potential marine traffic emissions from the dredgers would be expected.  However, only two dredgers would be operated at the work site, the associated emission should be limited.  Under normal operation, equipment with proper maintenance is unlikely to cause significant dark smoke emissions and gaseous emissions are expected to be minor. Thus, the AQOs are not expected to be exceeded.  Notwithstanding, plant should be regularly maintained to minimise emissions.

 

 

Compensation areas included:

Not required

 

Population and environmental sensitive receivers protected:

Existing air sensitive receivers within 500m of the project boundary.

 

Operational Air Quality Impact

Environmental benefits of environmental protection measures recommended:

In view of the project nature, no adverse air quality impact during the operation phase would be anticipated.

 

Compensation areas included:

Not required

 

Population and environmental sensitive receivers protected:

Existing and planned air sensitive receivers within 500m of the project boundary.

 

Construction Noise Impact

Environmental benefits of environmental protection measures recommended:

The predicted noise levels at representative NSRs would be in the range of 72 to 74 dB(A) in the absence of mitigation measures. Notwithstanding this, in order to further minimise the noise impacts at the NSRs, mitigation measures such as adopting quiet powered mechanical equipment are recommended.

 

 

Compensation areas included:

Not required.

 

 

Population and environmental sensitive receivers protected:

Noise sensitive receivers within 300m of the project boundary.

 

Operation Noise Impact

Considering the nearest noise sensitive receivers, Marco Polo Mansion and staff quarters of FEHD, are located at approximately 370m and 250m away from the temporary typhoon shelter mooring area, the noise impact during the operation phase of temporary typhoon shelter would not be considered significant.

Water Quality Impact

Environmental benefits of environmental protection measures recommended:

The assessment of hydrodynamic and water quality impacts associated with the proposed TBW have been assessed using the Delft3D model. The major water quality impact associated with dredging for construction of the TBW is the elevation of SS within the marine water column.  The TBW may also affect the dispersion pattern of the sediment plume potentially generated from dredging within the existing CBTS during construction of the CWB tunnel. Provided the recommended mitigation measures are implemented, including restriction on the maximum dredging rates, the deployment of silt curtains at the specified dredging areas, and installation of silt screens at seawater intakes, there would be no unacceptable residual water quality impact due to the proposed dredging works. In terms of the potential change of dispersion capacity for the polluted storm waters in the existing embayment of CBTS after the placement of the TBW, the model results indicated that no unacceptable water quality impacts would be expected during the TBW operation.

Compensation areas included:

Not required.

 

Population and environmental sensitive receivers protected:

Seawater intakes along the waterfront of Victoria Harbour and corals identified in Junk Bay, Green Island and Cape Collinson.

 

Waste Management Implications

Environmental benefits of environmental protection measures recommended:

With the implementation of the recommended mitigation measures and practices, potential air, odour, noise, water quality for the handling, transportation and disposal of the identified waste arisings, no adverse environmental impacts are expected.

Limited amount of refuse and debris may be unintentionally brought from the site into the harbour during heavy rains or typhoons. Given that the Project would not worsen the shoreline configuration and the implementation of appropriate control measures during construction phase, it is considered that the future quantity of refuse to be found along the shoreline would be similar if not better than the existing situation. With the implementation of a refuse collection system within the project area, no insurmountable environmental impact with regard to floating refuse would be anticipated during the construction phase, or after completion of the Project.

 

Compensation areas included:

Not required.

Population and environmental sensitive receivers protected:

·       Water quality, air, and noise sensitive receivers at or near the Project site, the waste transportation routes and the waste disposal site.

 

 

Land Contamination Impact

Environmental benefits of environmental protection measures recommended:

No potential contaminative land uses were identified within the Study Area.  As such, adverse land contamination impacts associated with the construction and operation of the Project  is not expected.

 

Compensation areas included:

Not required.

 

Population and environmental sensitive receivers protected:

No construction worker would be affected.

 

Marine Ecological Impact

Environmental benefits of environmental protection measures recommended:

The benthic, intertidal and subtidal habitats within the affected area are of very low ecological value. Hence, adverse direct ecological impact caused from temporary reclamation works is not expected. Water quality and noise control measures (as described above) would minimise indirect impact on marine habitats and associated flora and fauna due to change in water quality and noise environment during the construction phase.   

 

Compensation areas included:

Construction of about 1 km vertical wave absorbing seawall along the coastlines of the newly reclaimed land would provide large area of hard substrata for settlement and recruitment of similar intertidal fauna.

 

Population and environmental sensitive receivers protected:

Ecological resources in the assessment area.

 

Landscape and Visual Impact

Environmental benefits of environmental protection measures recommended:

·       A temporary typhoon shelter of approximately 6ha will be constructed outside existing typhoon shelter.

 

 

·       It is considered that the residual impacts on Victoria Harbour are moderate during construction phase but slight with implementation of mitigation measures and insubstantial during operation phase. 

 

 

·       With implementation of mitigation measures during construction, there will slight negative visual impact on the VSRs in the front row of high rise buildings along the waterfront from Central to North Point.  Residual impacts VSRs further away the Victoria Harbour and from the hinterland will become insubstantial.  During operation, there will be no impacts on all existing and planned VSRs.

 

 

 

Compensation areas included:

Approximately 13.8 ha of new waterfront open space and nine new pedestrian links to the new harbour-front will be provided

 

Population and environmental sensitive receivers protected:

Existing and planned Landscape Resources , Landscape Character Area and VSR at and near the project site.

 

Cultural Heritage Impact

Environmental benefits of environmental protection measures recommended:

Since there are no marine archaeological resources within the study area that would be affected by the project, marine archaeological impact due to the construction activities is not expected. The current project design would avoid the potential impact on the Kellett Island Archaeological Site at RHKYC and Noonday Gun at CBTS.  No environmental protection measure is required.

 

Compensation areas included:

Not required.

 

Population and environmental sensitive receivers protected:

Potential archaeological resources, and historical buildings and structures within the project area.

 

 

14.3          Air Quality Impact

 Construction Phase

14.3.1      Dredging and rock filling are the major construction works.  In view of marine based activities and a large separate distance between the ASRs and the work areas, no adverse dust impact at the nearest ASRs would be expected.  In accordance with the construction programme, there is no other construction activity to be operated concurrently within 500m study area of DP4, no cumulative impact is anticipated. 

14.3.2      Potential marine traffic emissions from the dredgers would be expected.  However, only two dredgers would be operated at the work site, the associated emission should be limited.  Under normal operation, equipment with proper maintenance is unlikely to cause significant dark smoke emissions and gaseous emissions are expected to be minor. Thus, the AQOs are not expected to be exceeded.  

14.3.3      Negligible dust impact and emission impact from dredging and rockfilling would be expected during construction phase of DP4 Project, air quality monitoring is not required.  However, requirements of the Air Pollution Control (Construction Dust) Regulation shall be adhered to during the construction period.  The operated dredgers should also be regularly maintained to minimise emissions.   

 


Operational Phase

14.3.4      In view of the project nature, no adverse air quality impact during the operation phase would be anticipated.

 

14.4          Noise Impact

Construction Phase

14.4.1      This assessment has predicted the construction noise impacts of the Project during normal daytime working hours, taking into account other concurrent projects including other Schedule 2 DPs. The predicted unmitigated noise levels would range from 72 to 74 dB(A) at the representative NSRs. Notwithstanding this, use of quiet PME and implementation of good site practices are recommended  for the Project to further minimise the noise impact at the NSRs.

14.4.2      No noise exceedances have been predicted at representative NSRs, the construction noise monitoring is therefore not considered required. However, weekly site inspection shall be carried out throughout the construction phase to ensure that appropriate noise control measures would be properly implemented with a view to minimizing the construction noise impact.

 

Operational Phase

14.4.3    Considering the nearest noise sensitive receivers, Marco Polo Mansion and staff quarters of FEHD, are located at approximately 370m and 250m away from the temporary typhoon shelter mooring area, the noise impact during the operation phase of temporary typhoon shelter would not be considered significant. 

 

14.5          Water Quality Impacts

14.5.1      The assessment of hydrodynamics and water quality impacts associated with the proposed TBW have been assessed by numerical modelling. The major water quality impact associated with dredging for construction of the TBW is the elevation of SS within the marine water column.  The TBW may also affect the dispersion pattern of the sediment plume potentially generated from dredging within the existing CBTS during construction of the CWB tunnel. Provided the recommended mitigation measures are implemented, including restriction on the maximum dredging rates, the deployment of silt curtains at the other specified areas within the WDII and CWB work site, and installation of silt screens at seawater intakes, there would be no unacceptable residual water quality impact due to the proposed dredging works. In terms of the potential change of dispersion capacity for the polluted storm waters in the existing embayment of CBTS after the placement of the TBW, the model results indicated that no unacceptable water quality impacts would be expected during the TBW operation.

 

14.6          Waste Management Implications

14.6.1      A review of the sediment quality data from the marine ground investigation indicated that the majority of marine sediments to be dredged for the project are classified as contaminated.  The total dredged volume is estimated as approximately 0.118 Mm3, of which 0.07 Mm3 is classified as contaminated (Category M and H) requiring Type 2 confined marine disposal, and 0.048 Mm3 is classified as Category L and would be suitable for Type 1 open sea disposal.  With the implementation of the recommended mitigation measures in accordance with the requirements of ETWB TCW No. 34/2002, no adverse residual impact is predicted.

14.6.2      Wastes generated by the construction activities will include C&D material, general refuse from the workforce and chemical waste from the maintenance of construction plant and equipment.  Surplus material would require disposal to designed public filling facilities (approximately 0.156Mm3).  Provided that these identified waste arisings are handled, transported and disposed of using approved methods and that recommended good site practice are strictly followed, adverse environmental impacts of air and odour emissions, noise, potential hazards, wastewater discharge and transport would not be expected during the construction phase.

14.6.3      Floating refuse is an existing waste and the Project itself will not generate floating refuse. Owing to the project area in close proximity to or within Victoria Harbour, limited amount of refuse and debris may be unintentionally brought from the site into the harbour during heavy rains or typhoons. Given that the Project would not worsen the shoreline configuration and with the implementation of appropriate control measures during construction phase, it is considered that the future quantity of refuse to be found along the shoreline would be similar if not better than the existing situation. Specialised refuse collection vessels currently operate in Victoria Harbour to provide a refuse scavenging and collection service. During the construction phase, the project proponent’s contractor will be responsible for the collection of any refuse within their works area. With the implementation of the refuse collection system within the project area, no insurmountable environmental impact with regard to floating refuse would be anticipated during the construction phase.  

 

14.7          Land Contamination Impact

14.7.1      No potential contaminative land uses were identified within the Study Area.  As such, no adverse land contamination impacts associated with the construction and operation of the Project is expected.

 

14.8          Marine Ecological Impact

14.8.1      Literature reviews of existing information supplemented with the results of recently undertaken field surveys on marine ecological resources indicated that identified marine habitats within the Assessment Area are of low ecological value.  There are no ecological sensitive receivers, such as SSSIs, Marine Parks and / or Reserves and other areas of ecological importance or conservation interest, in and within the immediate vicinity of the Assessment Area.

14.8.2      Direct and indirect ecological impacts arising from this designated project during construction phase were identified and evaluated. The designated project would result in the temporary loss of approximately 2.4 hectares of soft bottom benthic and subtidal habitats. Considering that the benthic and subtidal habitats within affected area are of very low ecological value, no adverse direct ecological impact is expected. 

14.8.3      Indirect disturbance impact on the associated waterbirds and other avifaunal species of conservation interest in the CBTS and Victoria Harbour was expected to occur during the construction phase of this project. Considering the existing background of intense human activities in these areas, the affected wildlife are considered already well adapted to human disturbance and therefore no adverse indirect impact is expected to occur.

14.8.4      Other impacts arsing from this project would be temporary and minimised with implementation of proper mitigation measures. Overall, no adverse ecological impacts on marine resources are anticipated.   

 


14.9          Landscape and Visual Impact

14.9.1      The proposed development and associated works follow in principle the planning intentions from the Metroplan, Visions and Goals for Victoria Harbour prepared by Town Planning Board and the views of the public received during the engagement exercises of the HER that was carried out under the steer of HEC Sub-committee on WDII Review.  In respond to the CFA judgment on the PHO, the extent of reclamation has been reduced to the minimum.  With the new waterfront development proposals together with enhanced connectivity to the waterfront from the hinterland and east-west linkages along the northshore, the landscape planning framework of the waterfront from Wan Chai to North Point is strengthened and reinforced by the proposed project.

14.9.2      A temporary typhoon shelter (DP4) with mooring area of approximately 4ha will be constructed in Victoria Harbour just outside existing typhoon shelter.  It is considered that the residual impacts on Victoria Harbour are moderate during construction phase but slight with implementation of mitigation measures and insubstantial during operation phase of the proposed WDII scheme.

14.9.3      The proposed temporary typhoon shelter (DP4) is temporary in nature. With implementation of mitigation measures during construction, there will slight negative visual impact on the VSRs in the front row of high rise buildings along the waterfront from Central to North Point.  Residual impacts VSRs further away the Victoria Harbour and from the hinterland will become insubstantial.  During operation of the proposed WDII scheme, there will be no impacts on all existing and planned VSRs.

 

14.10      Cultural Heritage Impact

14.10.1   The results of the MAI in 2001 (Report No. SDA8827) are applicable to the current study since they cover the same seabed area.  There have not been any significant changes to the seabed since 2001 which would have affected its archaeological potential. According to the MAI in 2001, it was concluded there were no archaeological resources within the project area of the temporary typhoon shelter.

 

14.11      Environmental Monitoring and Audit

14.11.1  Environmental monitoring and audit (EM&A) are recommended for construction dust monitoring, construction and operation noise, and water quality.  Site inspection / audit is also recommended for waste management during construction and also for implementation of landscaping measures during operation.  Details of the recommended mitigation measures, monitoring procedures and locations will be presented in a stand-alone EM&A Manual.  This will enable the Contractor to have early warning and provide necessary action to reduce impacts at specific areas if the assessment criteria are approached.  The effectiveness of on-site control measures could also be evaluated through the monitoring exercise.  All the recommended mitigation measures should be incorporated into the EM&A programme for implementation.


14.12      Overall Conclusion

14.12.1  The EIA has been conducted based on currently available information. and has been adequately addressed the environmental impacts of this Schedule 2 designated project. No outstanding issues were identified and hence further detailed EIA study was considered not necessary. The findings of this EIA have provided information on the nature and extent of environmental impacts arising from the construction and operation of the Project.  The EIA has, where appropriate, identified mitigation measures to ensure compliance with environmental legislation and standards.

14.12.2  Overall, the EIA Report for this DP has predicted that the Project will generally comply with the environmental standards and legislation after the proposed construction and operational stage mitigation measures are implemented.  This EIA has also demonstrated the general acceptability of the residual impacts from the Project and the protection of the population and environmentally sensitive resources.  Environmental monitoring and audit mechanisms have been recommended before and during construction and operation, where necessary, to verify the accuracy of the EIA predictions and the effectiveness of recommended mitigation measures.
