The EM&A programme also involved weekly site inspections and related auditings conducted by the ET for checking the implementation of the required environmental mitigation measures recommended in the approved EIA Report.

The EM&A programme followed the recommendations presented in the approved EIA Report and the Updated EM&A Manual. A summary of implementation status of the environmental mitigation measures for the construction phase of the Project during the reporting period is provided in Appendix C.

2 Environmental Monitoring and Auditing

2.1 Air Quality Monitoring

Impact 1-hour Total Suspended Particulates (TSP) monitoring was conducted three times every 6 days at two representative monitoring stations during the reporting period. The locations of monitoring stations are described in Table 2.1 and presented in Figure 2.1. The Action and Limit Levels of the air quality monitoring are also provided in Table 2.1 for reference.

Table 2.1: Impact Air Quality Monitoring Stations

Monitoring Station	Location	Action Level (mg/m³)	Limit Level (mg/m³)
AR1A	Man Tung Road Park	306	500
AR2	Village House at Tin Sum	298	500

The graphical plots of impact air quality monitoring results during the reporting period are presented in Graph 1.

Graph 1: Graphical Plot of 1-hour TSP concentration at AR1A and AR2 during the Reporting Period

Three exceedance cases of action level of air quality monitoring were recorded at AR1A on 27 September 2016 in the 1-hour TSP monitoring that started at 08:52am, 09:52am and 10:52am. Actions were taken accordingly based on the established Event and Action Plan as presented in the Updated EM&A Manual. IEC and AAHK were informed of the exceedances.

According to on-site observation by monitoring team, haze weather was observed during monitoring. No major construction dust emission source was observed during monitoring. Based on the information from Hong Kong Observatory, tropical cyclone Megi was approaching Taiwan, its subsidence airstream create unfavourable conditions for the dispersion of pollutants and lead to low visibility to Hong Kong. According to EPD’s pollutant concentration summary at Tung Chung from 08:00 to 12:00 on 27 September 2016, relatively high PM₁₀ ranging from 104 -159 µg/m³was recorded.

Relevant contractors were informed of the exceedances. As informed by the contractors, no major dusty activities were conducted during monitoring. The major land works were related to P560(R) HDD pilot hole drill, stockpiling of excavated materials and site preparation works at Sha Chau.

The exceedances of 1-hr TSP may possibly due to the air quality impact induced by tropical cyclone Megi. As no major project-related dusty construction work was conducted during monitoring, the exceedance was considered not due to 3RS project construction works and therefore, no repeat measurement is required.

No exceedance of the Action and Limit Level was recorded at AR2 in the reporting period.

The weather was varied from fine to rainy in the reporting quarter. Wind direction was mainly northeast or northwest in the reporting quarter.

Key activities of the Project were related to the Contract P560(R) which mainly involved installation of HDD casing and pilot hole drilling at the HDD launching site, stockpiling of excavated materials from HDD operation at stockpiling area, site preparation works and construction of containment pit on Sheung Sha Chau. CLP cable diversion enabling work contract involved site preparation works. The four DCM contracts involved mobilization and off-site plant fabrication. Those works were not likely to cause adverse dust pollution. The active construction works of Contract P560(R) were around 3 km and 900 m away respectively from the nearest monitoring stations in Tung Chung and the villages in North Lantau. The major dust sources during the reporting period were observed to be local air pollution and nearby traffic emissions. It is considered that the monitoring work in the reporting period was effective and there was no adverse impact attributable to the works of the Project.

2.2 Noise Monitoring

Impact noise monitoring was conducted at five representative monitoring stations once per week during 0700 and 1900 during the reporting period. The locations of monitoring stations are described in Table 2.2 and presented in Figure 2.1. The Action and Limit Levels of the noise monitoring are provided in Table 2.2 for reference.

The graphical plots of impact noise quality monitoring results during the reporting period are presented in Graph 2.

Table 2.2: Impact Noise Quality Monitoring Stations

Monitoring Station	Location	Action Level	Limit Level
NM1A	Man Tung Road Park	When one documented complaint is received from any one of the sensitive receivers	75 dB(A)

NM5	Village House in Tin Sum		75 dB(A)
NM6	House No. 1, Sha Lo Wan		75 dB(A)
Note: ⁽ⁱ⁾ reduce to 70dB(A) for school and 65dB(A) during school examination periods.

Graph 2: Graphical Plot of Leq _(30min) at NM1A, NM3A, NM4, NM5 and NM6 during the Reporting Period

No exceedance of the Action and Limit Level was recorded at all monitoring stations in the reporting period.

The key activities undertaken in the reporting period were not likely to cause adverse noise impact. The active construction works of Contract P560(R) were around 3 km and 900 m away respectively from the nearest monitoring stations in Tung Chung and the villages in North Lantau. The monitoring stations were observed during the construction noise impact monitoring dominated by aircraft noise at NM3A and NM5, aircraft noise and helicopter noise at NM6, road traffic noise at NM1A and school activities at NM4 in the background. It is considered that the monitoring work in the reporting period was effective and there was no adverse impact attributable to the works of the Project.

2.3 Water Quality Monitoring

Although no marine construction works was carried out, water quality monitoring was commenced as scheduled. The monitoring was conducted at a total of 22 water quality monitoring stations, comprising 12 impact stations, seven sensitive receiver stations and three control stations in the vicinity of the water quality sensitive receviers around the airport island in accordance with the Updated EM&A Manual. Table 2.3 describes the details of the monitoring stations. Figure 2.2 shows the locations of the monitoring stations.

2.5.2 Summary of Monitoring Results

Vessel Line-transect Survey

Survey Effort

During the reporting period, four complete sets of vessel line-transect surveys were conducted from August to September 2016 to cover all transects in NEL, NWL, AW, WL and SWL survey area twice per month.

A total of 939 km of survey effort was collected from these surveys, with around 94.5% of the total survey effort being conducted under favourable weather condition (i.e. Beaufort Sea State 3 or below with favourable visibility). Details of the survey effort data were presented in Appendix E.

Sighting Distribution

In August and September 2016, 37 groups of CWD with 142 individuals were sighted. Amongst the sightings of CWD, 31 groups with 128 individuals were made during on-effort search under favourable weather condition.

Distribution of CWD sightings recorded during August 2016 to September 2016 are illustrated in Figure 2.5. CWD sightings were more frequent in WL than in NWL and SWL. In NWL, sightings were mainly recorded to the northeast and to the southwest of Sha Chau and Lung Kwu Chau Marine Park (SCLKCMP). One sighting was recorded in AW near to the existing Hong Kong International Airport, whilst no sightings of CWDs were recorded within the 3RS land-formation footprint. CWD sightings in WL were evenly distributed in both coastal and off-shore areas from Tai O to Fan Lau. In SWL waters, CWD sightings were frequently sighted along the coast from Fan Lau to Lo Kei Wan, with a few scattered sightings further off-shore. Details of the sighting data were presented in Appendix E.

August 2016	3.48	14.17
Running Quarterly of August 2016	4.93	20.57
September 2016	3.50	14.65
Running Quarterly of September 2016	4.29	18.32

Note: For detailed calculations of encounter rates STG and ANI, please refer to the Monthly EM&A Reports No. 8 and No. 9.

Group Size

In August and September 2016, the group size of CWDs ranged from 1 to 10 individuals per group. The average group size of CWDs was 4.1 individuals per group. The numbers of CWD sightings with small group size (i.e. 1-2 individuals) and medium group size (3-9 individuals) were 12 and 18 respectively. The majority of CWD groups encountered in NWL were of medium group size. In WL, medium-sized CWD groups were mainly sighted along the coast. One large CWD group with 10 individuals was sighted in WL. Sighting locations of CWD groups with different group sizes were depicted in Figure 2.6.

Note: Only on-effort sightings under Beaufort 3 or below were presented in the figure.

Activities and Association with Fishing Boats

During August 2016 and September 2016, 19 groups of CWDs were sighted with feeding activities. Two groups amongst 19 were observed in association with operating purse seiners, one in WL and the other in SWL. In NWL waters, the majority of the feeding activities of CWDs were observed around SCLKCMP, while CWDs manily fed along the coast of WL and SWL during the current reporting months. The sighting locations of CWDs engaged in different behaviours during the current reporting months were illustrated in Figure 2.7.

Photo Identification

During August 2016 and September 2016, a total number of 52 different CWD individuals sighted altogether 68 times were identified. Amongst these 52 identified individuals, 13 animals (i.e. NLMM002, NLMM006, NLMM010, NLMM013, NLMM028, NLMM038, SLMM002, SLMM010, SLMM011, SLMM015, WLMM027, WLMM043 and WLMM054) were sighted more than once. A summary of photo identification works is presented in Table 2.10. Representative photos of these individuals may refer to Appendix E.

Re-sighting locations of the identified CWD individuals and further detailed analysis of CWD monitoring results collected by vessel survey during construction phase would be included starting from the next Quarterly EM&A Report when there are more data and photos collected.

Land-based Theodolite Tracking

Survey Effort

During August 2016 and September 2016, a total of 10 days of land-based theodolite tracking survey effort was completed, including six days on Lung Kwu Chau and four days on Sha Chau. In total, 21 CWD groups were tracked during the surveys. Information on survey effort and CWD groups sighted during these land-based theodolite tracking surveys are presented in Table 2.11. Details on the survey effort and CWD groups tracked are presented in Appendix E. The first sighting locations of CWD groups tracked during land-based theodolite tracking surveys in August 2016 and September 2016 are shown in Figure 2.9.

Progress Update on Passive Acoustic Monitoring (PAM)

An Ecological Acoustic Recorder (EAR) has been deployed and positioned to the south of Sha Chau Island with 20% duty cycle (Figure 2.10) with data from the EAR intended primarily to supplement the data collected from the land-based theodolite station on Sha Chau. The EAR deployment generally lasts around 4-6 weeks followed by a period of data retrieval for subsequent analysis. As the data analysis takes more than two months after retrieval, PAM results are not available for reporting in this quarterly report. Data transfer / analysis of this batch of PAM data is tentatively scheduled for completion by end of November 2016.

2.6 Weekly Environmental Site Inspection

Site inspections of the construction works were carried out on a weekly basis to monitor the implementation of proper environmental pollution control and mitigation measures for the Project. Bi-weekly site inspections were also conducted by the Independent Environmental Checker (IEC). Observations have been recorded in the site inspection checklist and passed to the Contractor together with the appropriate recommended mitigation measures where necessary.

The key observations from site inspection and associated recommendations were related to:

● improvement of efficiency and capacity of wastewater treatment facilities,

● proper maintenance of drip tray;

● provision of wheel washing before leaving the construction site;

● removal of oil stains on ground as chemical waste;

● review of the capacity of chemical waste storage area;

● display of Environmental Permit at site entrance;

● erection of site hoarding;

● provision of sandbags around the gully to prevent surface runoff; and

● improvement of dust mitigation measures.

In addition, CNP compliance check of the use of powered mechanical equipment for Contract P560(R) during restricted hour at the launching site was carried out by the ET on 11 July 2016. The use of powered mechanical equipment was complied with the requirements of CNP.

A summary of implementation status of the environmental mitigation measures for the construction phase of the Project during the reporting period is provided in Appendix C.

2.7 Ecological Monitoring

In accordance with the Updated EM&A Manual, ecological monitoring shall be undertaken monthly at the HDD daylighting location on Sheung Sha Chau Island to identify and evaluate any impacts with appropriate actions taken as required to address and minimise any adverse impact found.

Monthly ecological monitoring was carried out in August and September 2016 on Sheung Sha Chau Island. No encroachment or disturbance to the egretry area at Sheung Sha Chau was recorded during ecological monitoring.

2.8 Audit of the SkyPier Plan

In total, 2,459 ferry movements between HKIA SkyPier and Zhuhai / Macau were audited in the reporting period. The daily movements of all SkyPier HSFs in the reporting period ranged between 10 and 95, which falls within the maximum daily cap number of 125. There are fewer ferry movements on 1^st and 2^nd August 2016 (52 and 10 movements respectively) due to typhoon. Status of compliance with annual daily average of 99 movements will be further reviewed in the annual EM&A Report.

All the HSFs had travelled through the SCZ with prevailing speed within 15 knots (7.8 knots to 14.8 knots), which complied with the SkyPier Plan. 15 ferry movements had minor deviations from the diverted route during the reporting period. Notices were sent to the ferry operators and the cases have been investigated. In July, six cases recorded with the same ferry were not related to public safety / emergency situations. Warning letter has been issued to the concerned ferry operator to prevent reoccurrence. The ferry operator was requested to check the coordinates of SCZ plotted on the radar. Refresher training to the two concerned vessel captains was provided by experienced captain of the concerned ferry operator to ensure the captains are familiarised with the SkyPier Plan requirements. In August, one case was not related to public safety / emergency situations. Investigation found that the SCZ was plotted inaccurately in the radar graph and it was the first time the HSF used the diverted route. The ferry operator had checked and corrected the coordinates of SCZ in both the radar graph and electronic marine chart. The remaining eight cases are related to public safety / emergency situations. The summary of the Skypier Plan monitoring result (June to September 2016) is presented in Graph 3.

Two HSF movements with no transmission of AIS data received were reported during the reporting period. After investigation, it was found that missing of AIS data for concerned ferries were due to interference effect of AIS signal. Vessel captains were requested to provide the radar track photos which indicated the vessel entered the SCZ though the gate access point and no speeding in the SCZ. Ferry operator’s explanation has been accepted.

2.9 Audit of Construction and Associated Vessels

The audit of construction and associated vessels has been started in August. ET has conducted weekly audit of relevant information including AIS data, vessel tracks and other relevant records to ensure sufficient information has been provided by the contractors to the Marine Traffic Control Center (MTCC) and the contractors are complied with the requirements of the MTRMP-CAV. The contactors have been reminded to submit the endorsed vessel 3-month programme to MTCC for the review of keeping the number of construction vessels to a practicable minimum. The IEC has also performed audit on the compliance of the requirements as part of the EM&A programme.

A total of 11 skipper training workshops have been held in August and September with concerned captains of construction vessels associated with Contract P560(R) Aviation Fuel Pipeline Diversion Works and the four DCM contracts to familiarise them with the predefined routes, general education on local cetaceans, guidelines for avoiding adverse water quality impact, the required environmental practices / measures while operating construction and associated vessels under the Project, and guidelines for operating vessels safely in the presence of CWDs. Trainings have also been held in September with the 4 DCM and P560(R) contractor senior management staff to strengthen the communication between senior management and the sub-contractor and facilitating them in familiarise with the requirements of the MTRMP-CAV. In addition, a Marine Management Liaison Group (MMLG) has been set up and provided a forum to assist and resolve any marine issues which may be encountered under 3RS project. The 2nd MMLG meeting was held on 26 September 2016.

2.10 Review of the Key Assumptions Adopted in the EIA Report

With reference to Appendix E of the Updated EM&A Manual, it is noted that the key assumptions adopted in approved EIA report for the construction phase are still valid and no major changes are involved. The environmental mitigation measures recommended in the approved EIA Report remain applicable and shall be implemented in undertaking construction works for the Project.

4 Conclusion and Recommendation

In this quarterly period from 1 July 2016 to 30 September 2016, the EM&A programme has been implemented as planned, including 99 sets of air quality measurements, 65 sets of construction noise measurements, two ecological monitoring on Sheung Sha Chau Island, as well as environmental site inspections, landscape & visual and waste monitoring for the Project’s construction works.

Twenty-five sets of water quality measurements, four complete sets of vessel line-transect surveys and ten days of land-based theodolite tracking survey effort for Chinese White Dolphin (CWD) monitoring were completed as scheduled although no marine construction works was carried out during the reporting period.

Key activities of the Project carried out in the reporting period were related to Contract P560(R) which involved installation of HDD casing and drilling of HDD pilot hole at launching site, stockpiling of excavated materials from HDD operation at stockpiling area, site preparation works and construction of containment pit at Sheung Sha Chau. Works under the four DCM contracts involved mobilization and off-site plant fabrication, and CLP cable diversion enabling work involved site preparation works. Some other site investigation works were also carried out during the reporting period.

Three exceedance cases involving Action Level of 1-hour TSP monitoring were recorded during the reporting period. The investigation results indicated that the exceedances were likely related to background air quality level but not project-related.

No breach of the Action or Limit Levels in relation to the construction noise and waste monitoring were recorded in the reporting month. All site observations made by the ET were recorded in the site inspection checklists and passed to the Contractor together with the recommended follow-up actions. No encroachment or disturbance to the egretry area on Sheung Sha Chau was recorded during monthly ecological monitoring.

In total, 2,459 ferry movements between HKIA SkyPier and Zhuhai / Macau were audited in the reporting period. All the HSFs had travelled through the SCZ with prevailing speed within 15 knots, which complied with the SkyPier Plan. Fifteen ferry movements had minor deviation from the diverted route during the reporting period. Among the 15 cases, eight cases are related to public safety / emergency situations. Follow-up actions such as checking of electronic marine chart / radar graphs and refresher training have been taken for the remaining non-public safety / emergency cases.

The audit of construction and associate vessels has been started in August. ET has conducted weekly audit of relevant information to ensure sufficient information has been provided by the contractors to the Marine Traffic Control Center (MTCC) and the contractors are fully complied with the requirements of the MTRMP-CAV. A total of 11 skipper training workshops have been held in August and September with concerned captains of construction vessels associated with Contract P560(R) Aviation Fuel Pipeline Diversion Works and the four DCM contracts to familiarise them with the MTRMP-CAV.

The recommended environmental mitigation measures, as included in the EM&A programme, have been effectively implemented during the reporting period. Also, the EM&A programme implemented by the ET has effectively monitored the construction activities and ensure the proper implementation of mitigation measures.
