2.4.3 Monitoring Parameter, Frequencies and Duration

Dolphin monitoring should cover 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 should be 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.

2.4.4 Monitoring Location

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 2.11 below.

2.4.5 Action & Limit Levels

The Action and Limit levels of dolphin impact monitoring are shown in Appendix D. The Event and Action plan is presented in Appendix L.

2.4.6 Monitoring Schedule for the Reporting Month

Dolphin monitoring was carried out on 2, 9, 15 and 23 of December 2014 (Appendix F).

2.4.7 Results and Observations

A total of 299.10 km of survey effort was collected, with 100% of the total survey effort being conducted under favourable weather conditions (i.e. Beaufort Sea State 3 or below with good visibility) during the surveys in December 2014. Among the two areas, 115.70 km and 183.40 km of survey effort were collected from NEL and NWL survey areas respectively. The total survey effort conducted on primary and secondary lines were 217.18 km and 81.92 km respectively. The survey efforts are summarized in Appendix K.

A total three (3) groups of five (5) Chinese White Dolphins were sighted during the two sets of monitoring surveys in December 2014 (Appendix K). All sightings were made in NWL during the two sets of surveys in December 2014, while no dolphin was sighted at all in NEL in this reporting month. All three (3) sightings were made on primary lines during on-effort search, and none of the dolphin groups was associated with operating fishing vessel. No sighting was made in the proximity of the Project’s alignment. The distribution of dolphin sightings during the reporting month is shown in Figure 2.5.

Encounter rates of Chinese White Dolphins are deduced from the survey effort and on-effort sighting data made under favourable conditions (Beaufort 3 or below) in December 2014 are shown in Tables 2.12 and 2.13.

Table 2.12 Individual Survey Event Encounter Rates

		Encounter rate (STG) (no. of on-effort dolphin sightings per 100 km of survey effort)	Encounter rate (ANI) (no. of dolphins from all on-effort sightings per 100 km of survey effort)

	Primary Lines Only	Both Primary and Secondary Lines	Primary Lines Only	Both Primary and Secondary Lines
Northeast Lantau	0.0	0.0	0.0	0.0
Northwest Lantau	2.1	1.6	3.5	2.7

Note: Overall dolphin encounter rates (sightings per 100km of survey effort) from all four surveys are conducted in December 2014 on primary lines only as well as both primary lines and secondary lines in Northeast and Northwest Lantau

The average group size of Chinese White Dolphins in December 2014 was 1.67 individuals per group, which was much lower than the ones in previous months of dolphin monitoring. All three (3) dolphin groups were composed of only one to three (1-3) animals during the monitoring period. Detailed results of dolphin monitoring in this reporting month are presented in Appendix K.

Due to monthly variation in dolphin occurrence within the study area, it would be more appropriate to draw conclusion on whether any impacts on dolphins have been detected related to the construction activities of the TM-CLKL Southern Connection Viaduct Section in the quarterly EM&A reports, where comparison on distribution, group size and encounter rates of dolphins between the quarterly impact monitoring period and baseline monitoring period will be made.

2.4.8 Marine Mammal Exclusion Zone Monitoring

Daily 250 m marine mammal exclusion zone monitoring was undertaken during the period of marine works activities being undertaken. Passive Acoustic Monitoring (PAM) was implemented when the marine works were carried out outside the daylight hours in this reporting month. No sighting of Indo-Pacific humpback dolphin Sousa chinensis (i.e. Chinese White Dolphin) were recorded in December 2014 during the exclusion zone monitoring.

2.5 EM&A Site inspection

Site inspections were carried out on a weekly basis to monitor the implementation of proper environmental pollution control and mitigation measures under the Contract. In the reporting month, five (5) site inspections were carried out on 3, 10, 17, 24 and 30 December 2014.

Key observations during the site inspections are summarized in Table 2.14.
