1 Introduction

1.1 Introduction

On 27 August 2014, the Environment Impact Assessment (EIA) Report and Environmental Monitoring and Audit (EM&A) Manual (Register No.: AEIAR-184/2014) for the “Tai Shue Wan Development at Ocean Park” (the Project) was approved and an Environmental Permit (EP) (Permit No.: EP-487/2014) was issued to the Ocean Park Corporation (Project Proponent).

The current valid EP (Permit No.: EP-487/2014/A) was issued on 10 January 2018 based on the Variation of Environmental Permit No. VEP-539/2017 which comprised variation of project boundary, location of sump pit and size of rising main. The Project location is indicated in Appendix A.

Baseline monitoring for the required parameters including background noise, landscape & visual baseline review and baseline ardeid inspection were carried out between 24 October 2014 and 10 December 2014 by the environmental consultants of Ocean Park Corporation. Furthermore, the baseline monitoring report verified by the previous Independent Environmental Checker (IEC) was submitted to the EPD and endorsed in December 2014.

The previous contract (Contract No. TSW-C004) of Site Formation and Foundation Works has been completed since 31 May 2017, while the Project site was handed over to Gammon Engineering & Construction Company Limited on 31 May 2017 for the Main Building Works (Contract No. TSW-C006, the Contract). Mott MacDonald Hong Kong Ltd. (MMHK) has been commissioned by Gammon Engineering & Construction Company Limited to undertake the Environmental Team (ET) services to carry out environmental monitoring and audit for the Ocean Park Tai Shue Wan Water World Project.

The major construction works have been completed by May 2021 with the Occupation Permit obtained on 7 May 2021. The proposal for suspension of the construction phase environmental monitoring (including weekly noise monitoring and environmental site audits) by end of June 2021 was justified by the ET Leader and verified by the IEC on 23 June 2021, approved by EPD on 6 July 2021 and implemented on 6 July 2021.

The termination of construction EM&A Programme by 31 August 2021 was proposed by the Contractor on 30 August 2021 and is supported by ET and endorsed by IEC and ER as conforming the requirements set out in the EM&A Manual. It was accepted by EPD on 29 September 2021.

Meteorological information including temperature, humidity, wind direction and wind speed was extracted from “the Hong Kong Observatory Wong Chuk Hang Station” to provide background weather information. The meteorological data during the monitoring period is summarised in Appendix G.

4.2 Ecology Monitoring

Monthly ecological monitoring has been conducted from June 2017 to June 2021 during the construction period. Monitoring has been carried out by inspections of preservation of the plant of conservation interest, ardeid nest, ardeid night roost and ecological enhancement area within the Project Area.

Monitoring of Plant Species of Conservation Interest (Platycondon grandiflorus)

Platycodon grandiflorus is a perennial herb up to 120 cm tall. Stems erect with scarcely any branches. It is often found on sunny grassy hillslopes in bushes. Two groups of Platycodon grandiflorus were recorded in 2015’s growing season within the fenced area.

During the construction period, the preventive mitigation measures, i.e., erecting of temporary protective fencing and sign post, were found to be effectively implemented to protect the Platycodon grandiflorus from human disturbance, and there was no signs or evidence (e.g. dust coating of plant) suggesting the on-going construction activities within the Project Area has affected the health condition of the Platycodon grandiflorus. In general, the Platycodon grandiflorus was in good health condition and has been growing according to the natural life cycle. Table 4.3 summarised the special observations on the growth of Platycodon grandiflorus related to typhoon events during the construction period.

Table 4.3: Summary of special observations of Platycodon grandiflorus

Month	Special Observation
August 2017	It was observed that the whole plant prostrated on the ground due to severe typhoon HATO battered Hong Kong on 23 August 2017. The Hong Kong Observatory issued the highest Tropical Cyclone Warning Signal – Hurricane Signal No.10 and the sea level rose above normal chart datum. It was expected that severe typhoon and high sea water level caused adverse impact to the Platycodon grandiflorus because of the strong wind and its low salt tolerant. Close monitoring on the Platycodon grandiflorus was recommended.
September 2017	It was observed that new branches were grown from the stem in both two groups after the severe typhoon HATO battered Hong Kong on 23 August 2017.
October 2018	No Platycodon grandiflorus was observed due to super typhoon Mangkhut battered Hong Kong on 16 September 2018. The Hong Kong Observatory issued the Hurricane Signal No.10 and sea level rose above normal chart datum. It was expected that super typhoon and high sea water level caused adverse impact to the Platycodon grandiflorus because of the strong wind and its low salt tolerant. Close monitoring on the Platycodon grandiflorus was recommended.
November 2018	It was observed that new stems were grown in both two groups after the super typhoon Mangkhut battered Hong Kong on 16 September 2018.

As recorded during the last ecological inspection event in June 2021, it was observed that Group 2 of Platycodon grandiflorus was found to be vigorous and was in good health condition. However, Group 1 of Platycodon grandiflorus could not be found within the fenced area due to natural life cycle of this perennial herbaceous species, and new shoots would be expected to emerge from the underground part in the next growing season. The latest photo of the Platycodon grandiflorus is shown in Appendix H.

Nesting Activities of Ardeids in Breeding Season

No signs or breeding (such as courtship, nest building, brooding, juveniles etc.) of ardeids were noted within the Project Area during the monitoring period throughout the construction phase.

Roosting Activities of Ardeids in Peak Wintering Season

No ardeids were noted roosting within or in the vicinity of the project area in the evening from an hour before sunset to nightfall during the monitoring period throughout the construction phase.

Compensation for Ardeid roosting Site

The site of proposed Ecological Enhancement Area was prepared in the first phase of construction in early 2020. In accordance with the approved Ecological Enhancement Plan, the tree planting within the Ecological Enhancement Area was being implemented and completed in July 2021. Monitoring of the compensation at the Ecological Enhancement Area will be implemented during the operation phase.

Compensation of Woodland Habitat

The establishment of woodland compensation will be implemented after the commencement of operation.

4.3 Landscape and Visual Monitoring

Bi-weekly landscape and visual site inspection has been conducted from June 2017 to June 2021 during the construction period. Throughout the construction period, the Contractor complied with the intended aims of mitigation measures. Non-compliance was not recorded, and the Event and Action Plan for landscape and visual impact was not triggered. Only a few observations related to typhoon events were being recorded as summarised in Table 4.4, where recommended actions have been undertaken by the Contractor immediately after the events.

Table 4.4: Summary of Observations on Landscape and Visual Impact

Month	Observation
August 2017	On 23 August 2017, severe typhoon HATO battered Hong Kong. The Hong Kong Observatory issued the Hurricane Signal No.10 and sea level rose above normal chart datum, some of the trees including A0090 and A0091 were observed with yellowing of normally green leaves and large portion of drooping leaves on 25 August 2017. Close monitoring of these trees was recommended. Also, loose wire was observed, tighten up of the wire is recommended.
September 2017	On 22 September 2017, A0090 and A0091 were observed with new leaves. Although new leaves observed on these trees, close monitoring was still recommended.
October 2018	Crown damage was observed on Royal Palm due to super typhoon Mangkhut battered Hong Kong on 16 September 2018. Close monitoring of these Royal Palm was recommended.
November 2018	A few Royal Palm were found dead during reporting period due to super typhoon Mangkhut battered Hong Kong on 16 September 2018. Removal of the dead trees and tree replacement were recommended.
December 2018	Dead Royal Palms due to super typhoon Mangkhut battered Hong Kong on 16 September 2018 were removed. Tree replacement for dead Royal Palms and regular weeding in the tree protection zone were recommended.

In accordance with the approved Visual and Landscape Plan, the landscape planting and related greening works of the Project has been implemented and completed in August 2021. The monitoring of landscape planting will be conducted in operation phase.

4.4 Waste Management

The Contractor has been registered as a chemical waste producer for the Project. Construction and demolition (C&D) material sorting was carried out on site. Reuse of inert C&D material was adopted as far as practicable. Recyclable non-inert C&D materials were sorted and sent to recycling facilities. Sufficient number of receptacles were available for general refuse collection. The summary of waste generated during the construction period is presented in Appendix I.

4.5 Site Inspection

Site inspection has been undertaken by the PMR, ET and the Contractor weekly and site inspection and audit were performed by the IEC monthly from June 2017 to June 2021 during the construction period. In view of the completion of construction activities which may potentially cause significant environmental impact, the weekly site inspection has been suspended from July 2021 as approved by the EPD. During the site inspections, non-compliance was not observed by ET and IEC.

5 Summary of Environmental Quality Performance Limits

5.1 Summary of Non-compliance of Action and Limit Levels

No exceedance of Action or Limit Levels of construction noise or triggering of Event and Action Plan for visual and landscape impact were recorded in this period.

5.2 Summary of Environmental Complaints Received

During the construction period, a total of four cases of environmental complaints were received regarding construction noise issue. Three of the complaints were considered unlikely to be related to the construction works of the Project, while one of the complaints was considered as project related. The complaint investigations are summarised in Table 5.1.

Table 5.1: Summary of Complaint Investigations

Date of Complaint	Descriptions	Result of investigation	Actions / Recommendations
3 March 2018	The complaint was about noise generated by construction equipment and construction vehicles movement at midnight from the construction site of Ocean Park Tai Shue Wan Water World Project.	● As Shum Wan Road experienced congested traffic during daytime, the planned concreting works had been extended beyond 19:00. ● Referring to the information provided by the site team, no works was carried out during the incident period. ● It is noted that the Contractor obtained a valid Construction Noise Permit (CNP) permitting the use certain powered mechanical equipment (PME) including PME for concreting works during restricted hours between 23 November 2017 and 16 May 2018. The listed PME and no. of units have been strictly followed to CNP. ● The complaint was unlikely to be related to the construction works on the Project site due to no construction works was carried out during the incident period.

5.3 Summary of Notifications of Summons and Successful Prosecutions

No notifications of summons or successful prosecution were received during the construction period of the Project.

6 Review of the Validity of EIA Predictions

6.1 Construction Noise

It was predicted in the EIA report that with the implementation of good site practices and mitigation measures including the use of quiet PME and movable noise barriers in place, there would be no residual construction noise impact exceeding the relevant noise criteria at all noise sensitive receivers (NSRs).

Throughout the construction phase, construction site mitigation measures were properly implemented without any non-compliance observation during site inspections. The construction noise monitoring results remained below 70 dB(A) demonstrating that no Limit Level exceedance was recorded throughout the construction EM&A programme. This is in-line with the EIA predictions.

6.2 Ecological Monitoring

The potential ecological impacts of the Project as predicted in EIA include habitat loss, impact on plant species of conservation interest, impact on ardeid’s breeding and roosting, and disturbance impact on fauna. It was predicted that with implementation of the recommended mitigation measures for the project, all residual ecological impacts were anticipated as minor to negligible.

During the construction phase, mitigation measures proposed in the EIA report were implemented as inspected during site audits for ecological monitoring, such as erection of the protective fencing for the plant species of conservation interest. It was observed that the ecological impacts have been minimised as per the EIA predictions. Monitoring on the effectiveness of the compensatory measures would be conducted during the operation phase in accordance with the relevant approved submissions/plans under the EP.

6.3 Landscape and Visual Monitoring

The EIA report has predicted that with the implementation of proposed landscape and visual mitigation measures, the anticipated impacts would be generally moderate adverse to insubstantial during construction phase. Overall, the EIA report concluded that the landscape and visual impacts are acceptable with mitigation measures.

During the construction phase, the landscape and visual mitigation measures were compiled by the Contractor as observed from site inspection for landscape and visual monitoring. No major environmental deficiency in landscape and visual mitigation measures or triggering of Event and Action Plan for landscape and visual impact were recorded throughout the construction period. The landscape and visual impacts were mitigated by provisional of planting and greening upon completion of construction as predicted in the EIA.

7 Review of EM&A Programme

The EM&A programme requires construction phase monitoring for noise, ecology, landscape and visual aspects. All monitoring works were conducted as scheduled. The EM&A programme is effective in monitoring impacts arising from the Project. The overall performance and cost effectiveness of the monitoring methodology adopted were deemed effective.

Throughout the construction phase, observations and deficiencies recorded during site inspections were reflected to the Contractor immediately and relevant follow-up actions were being implemented timely. This effectively prevented potential significant environmental impacts from the construction activities. The weekly environmental site inspections also ensured that all the environmental mitigation measures recommended were effectively implemented. With implementation of the recommended environmental mitigation measures, the environmental impacts of the Project were considered environmentally acceptable.

The recommended environmental mitigation measures, as included in the EM&A programme, effectively minimised the potential environmental impacts from the Project as no environmental non-compliances were recorded. Also, the EM&A programme monitored the environmental impacts from the construction activities effectively and ensured proper implementation of the mitigation measures. There is no recommendation for the improvement of the EM&A programme.

8 Conclusion

The EM&A programme for construction of the subject works was performed from 1 June 2017 to 31 August 2021. Monitoring of construction noise, ecology, landscape and visual impacts for the Project were conducted as scheduled in the construction period. All monitoring and audit results and findings in the construction period were checked and reviewed.

Construction noise monitoring results revealed that the noise levels at NSRs during construction were similar with that recorded during baseline monitoring. No exceedance of Action or Limit Levels of construction noise was recorded. On the other hand, ecological monitoring inspections revealed that mitigation measures proposed in the EIA were implemented and ecological impacts were minimised as per EIA predictions. For visual and landscape impact monitoring, there was no triggering of Event and Action Plan during the reporting period. No notification of summons of successful prosecutions were received or made against the subject works of the Project during the construction period.

Environmental complaints received during the construction period are related to construction noise. The complaint investigation results have shown that most complaints were considered unlikely to be related to the construction works of the Project. For the single complaint that was considered as project related, the investigation result demonstrated that the Contractor complied with the relevant EP conditions or the CNP conditions.

The overall EM&A programme to examine the potential environmental impacts of the Project and evaluate the predictions of the EIA report has provided solid proof that it has been working well according to the intention of the EIA framework in Hong Kong.
