(2) Notification of temporary suspension of noise monitoring has been approved by EPD on 28 August 2019. No construction noise monitoring was scheduled since 28 August 2019.
In general, the average impact noise monitoring results recorded in the impact monitoring period were within the range of the predicted noise levels in the EIA Report and thus suggested that no unacceptable level of construction noise generated from the Contract during the impact monitoring period.
The baseline water quality monitoring undertaken by the HZMB Projects between 6 and 31 October 2011 included all monitoring stations except SR4a for the Project. Thus, the baseline monitoring results except for station SR4a and Action/Limit Level presented in HZMB Baseline Monitoring Report ([3]) are adopted for this Project. Baseline water quality monitoring was conducted at station SR4a from 29 August to 24 September 2013.
Results of water quality monitoring for the period between June and July 2017 were adopted from the published EM&A data of Contract No. HY/2010/02 Hong Kong-Zhuhai-Macao Bridge Hong Kong Boundary Crossing Facilities – Reclamation Works ([4])([5]).
Results of water quality monitoring in July and August 2019 were adopted from the published EM&A data of Contract No. HY/2012/08 Tuen Mun-Chek Lap Kok Link – Northern Connection Sub-sea Tunnel Section ([6]).
In accordance with the Updated EM&A Manual, impact water quality monitoring was undertaken three (3) days per week during mid-ebb and mid-flood tides in the construction period at seven water quality monitoring stations.
The water quality monitoring stations for the Contract are provided in Table 2.11 and is shown in Figure 2.3.
Details of the equipment deployed in water quality monitoring are provided in Table 2.12.
According to the Updated EM&A Manual, a post-construction water quality monitoring was carried out upon completion of all marine-based construction activities. Post-construction water quality monitoring was undertaken three (3) days per week for at least 4 weeks. The proposal for post-construction water quality monitoring was approved by EPD on 19 November 2019. Post-construction water quality monitoring commenced on 27 November 2019 and completed on 23 December 2019.
Operational phase water quality monitoring was undertaken by Contract No. HY/2012/08 Tuen Mun-Chek Lap Kok Link – Northern Connection Sub-sea Tunnel Section.

In general, DO, turbidity and suspended solids levels were varied across the impact monitoring period and these variations were however not consistent throughout the impact monitoring period.
According to the EIA prediction, no SS exceedance was anticipated from this Project at the water sensitive receivers nearby the vicinity of Contract (WSR 22a, WSR 22b and WSR 22c). Although exceedances on depth-averaged SS were recorded in the impact monitoring period, the exceedances were considered not related to this Contract upon further investigation. The impact monitoring results were considered influenced by fluctuation of background regional water quality instead of indicating any unacceptable impacts from this Contract.
During the post-construction water quality monitoring, no non-compliance of the water quality limit for DO, turbidity and suspended solids levels was recorded.
Impact dolphin monitoring is required to be conducted by a qualified dolphin specialist team to evaluate whether there have been any effects on the Indo-Pacific humpback dolphin Sousa chinensis (i.e. Chinese White Dolphin) from the Contract. In order to fulfil the EM&A requirements and make good use of available resources, the impact line transect dolphin monitoring data was collected by HyD’s Contract No. HY/2011/03 Hong Kong-Zhuhai-Macao Bridge. Hong Kong Link Road - Section between Scenic Hill and Hong Kong Boundary Crossing Facilities between November 2013 and September 2019 and Contract No. HY/2012/08 TMCLKL Northern Connection Sub-Sea Tunnel Section between October 2019 and February 2020.
Operational phase dolphin monitoring was undertaken by Contract No. HY/2012/08 Tuen Mun-Chek Lap Kok Link – Northern Connection Sub-sea Tunnel Section.
Table 2.20 summarizes the equipment used for the impact dolphin monitoring.

The dolphin monitoring covered all transect lines in Northeast Lantau (NEL) and the Northwest Lantau (NWL) survey areas twice per month throughout the entire construction period. The monitoring data were compatible with, and should be made available for, long-term studies of small cetacean ecology in Hong Kong. In order to provide a suitable long-term dataset for comparison, identical methodology and line transects employed in baseline dolphin monitoring was followed in the impact dolphin monitoring.
The impact dolphin monitoring was carried out in the NEL and NWL along the line transect as depicted in Figure 2.4. The co-ordinates of all transect lines are shown in Table 2.21 below.

11 Action Level and 19 Limit Level exceedances were recorded for dolphin monitoring during the impact monitoring period. Detailed investigation reports on exceedances were presented in First to Twenty-fifth Quarterly EM&A Reports.
According to the baseline results of the approved EIA Report, the dolphin groups were largely sighted near waters around Lung Kwu Chau and Sha Chau. There was no dolphin sighted along the alignment of this Contract. Dolphins are observed heavily utilized area around Lung Kwu Chau and less frequently in the North Lantau region where the works area of this Contract is situated. The monitoring results in the impact monitoring period are considered to be in line with the EIA predictions, and the review of monitoring data suggested that no unacceptable impacts was noted from the marine works under this Contract.
Daily marine mammal exclusion zone monitoring was undertaken between November 2013 and June 2019 during the period of marine works under this Contract. No marine works were undertaken since July 2019, therefore, daily 250 m marine mammal exclusion zone monitoring was not undertaken since July 2019.
Passive Acoustic Monitoring (PAM) was undertaken between September 2014 and September 2015 as marine piling works was carried out outside the daylight hours.
During the exclusion zone monitoring, one sighting of the Indo-Pacific humpback dolphin Sousa chinensis within the 250 m marine mammal exclusion zone of the landing platform workfront nearby Viaduct D was recorded on 23 January 2014 by the marine mammal observer during the daylight hours, and the marine construction work was subsequently suspended. The Dolphin Intrusion Report is presented in the Appendix K of the Third Monthly EM&A Report.
Baseline bored piling monitoring, including land-based theodolite tracking, underwater noise monitoring and acoustic behavioural monitoring, were undertaken from September to October 2013 by qualified dolphin specialist. Detailed baseline monitoring results and Action/ Limit Level are presented in the Baseline Monitoring Report ([7]) under this Contract.
Impact monitoring of bored piling monitoring was conducted from 3 March to 25 April 2014. Schedule of bored piling monitoring are detailed in the Fifth and Sixth Monthly EM&A Reports. Due to rare occurrence of dolphin in the study area, no impact associated from bored piling works could be identified. Action and Limit Level Exceedances were however recorded in the Underwater Noise and Acoustic Behavioural Monitoring. Actions were taken according to the Event Action Plan (Appendix G). The detailed results of impact bored piling monitoring are presented in the Impact Monitoring Report for Underwater Noise and Dolphin Acoustic Behavioural Monitoring and Impact Monitoring Report for Land-based Dolphin Behavioural and Movement Monitoring submitted under separate covers.
4 events of Post-Translocation Coral Monitoring were conducted on 17 January, 16 April, 24 July and 23 October 2014 and no exceedance of Action nor Limit Levels was recorded. The results were detailed in the First to Fourth Quarterly Post-Translocation Coral Monitoring Reports. The findings indicated that no Action or Limit Levels exceedances was recorded for coral monitoring as increase in percentage of partial mortality was not detected for both the tagged translocated and natural coral colonies when comparing to the pre-translocation dataset.
The result is in a line with the EIA prediction as the impact on coral was predicted minor.
Site inspections were carried out on weekly basis to monitor the implementation of proper environmental pollution control and mitigation measures under the Contract. A total of 330 site inspections were carried out in the impact monitoring period. Key observations were summarized in the section of EM&A Site Inspection in the First to Seventy-seventh Monthly EM&A Reports. The Contractor has rectified all of the observations identified during environmental site inspections in the impact monitoring period.
Wastes generated during the impact monitoring period include construction wastes (inert and non-inert), imported fill, recyclable materials, chemical waste and marine sediments. The summary of waste generation amount is presented in Appendix H.
Waste
monitoring and audit programme has been undertaken during the impact monitoring
period. Wastes arising from this Contract have been managed in
accordance with the recommendations in the EIA Report, the EM&A Manual, the
Waste Management Plan and other relevant statutory requirements.
