	Primary Lines Only	Both Primary and Secondary Lines	Primary Lines Only	Both Primary and Secondary Lines
Northeast Lantau	1.4	1.0	4.1	3.1
Northwest Lantau	6.9	5.3	29.6	22.6

Note: Overall dolphin encounter rates (sightings per 100km of survey effort) from all four surveys are conducted in December 2013 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 2013 was 4.13 individuals per group. Six of the eight dolphin groups were composed of only 1-4 animals, while the other two were larger groups with six (6) and twelve (12) animals per group respectively.

During this month of dolphin monitoring, no unacceptab impact from the construction activities of the TM-CLKL Southern Connection Viaduct Section on Chinese White Dolphins was noticeable from general observations

Due to monthly variation in dolphin occurrence within the Study area, it would be more appropriate to draw conclusion on whether any unacceptable 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.

4 Conclusions and recommendations

4.1 Conclusions

This second Monthly EM&A Report presents the findings of the EM&A activities undertaken during the period from 1 to 31 December 2013, in accordance with the Updated EM&A Manual and the requirements of EP-354/2009/A.

Air quality (including 1-hour TSP and 24-hour TSP), noise, water quality and dolphin monitoring were carried out in the reporting period. Two (2) exceedanced of Action Levels for 24-hr TSP were recorded in this reporting month. The review of monitoring data and works activities undertaken suggested that the exceedance was not due to the Contract works. Nevertheless, the Contractor was reminded to ensure all dust mitigation measures are provided at the construction site.

Results for noise, 1-hr TSP monitoring and impact water quality monitoring complied with the Action/ Limit levels in the reporting period.

A total of eight (8) groups of thirty-three (33) dolphins sighting were recorded during the two sets of surveys. All except one sighting were made in NWL during the two sets of surveys with one sighting made in NEL in December 2013. None of the 33 sightings was made in the proximity of the TM-CLKL Southern Connection Viaduct Section. During this reporting period of dolphin monitoring, no unacceptable impact from the construction activities of the TM-CLKL Southern Connection Viaduct Section on Chinese White Dolphins was noticeable from general observations.

Environmental site inspection was carried out four (4) times in December 2013. Recommendations on remedial actions were given to the Contractor for the deficiencies identified during the site audits.

No environmental complaint, notification of summons and prosecution were received in the reporting month.
