Results and Observations. 2.7.1 The monitoring results for 1-hour TSP and 24-hour TSP are summarized in Table 2.4 and 2.5 respectively. Detailed impact air quality monitoring results are presented in Appendix G.

Results and Observations. 5.7.1 Dolphin surveys were conducted on 4, 5, 18 and 19 December 2014. A total of 219.3 km of transect line was conducted all of which during Beaufort Sea State 3 or better (favourable water conditions). Please note that that some lines were shortened due to works and/or shipping traffic. The effort summary and sightings data are shown in Tables 5.3 and 5.4, respectively. The survey efforts conducted in December 2014 are plotted in Figure 5a-b. For Table 5.3, only on-effort information is included. Transects conducted in all Beaufort Sea State are included. Compared to previous monthly reports, the whole number Beaufort Sea State scale is used so as to ease comparison with other dolphin monitoring reports.

Results and Observations. 5.7.1 Dolphin surveys were conducted on 1, 2, 22 and 23 April 2013. In summary, a total of 205.3km of “on effort“ survey was conducted while 92% of “on effort” survey was conducted under favourable conditions (Beaufort Sea State 3 or better). The details are shown below:-
Results and Observations. 4.7.1 Impact water quality monitoring results and graphical presentations are provided in Appendix J.
Results and Observations. 4.7.1 Impact water quality monitoring was conducted at all designated monitoring stations in the reporting month. Except Impact water quality monitoring at sampling location IS(Mf)9. Sampling location IS(Mf)9 was found enclosed by silt curtain during the reporting month. Samples were taken about 140 meters away from IS(Mf)9. The sampling location‟s coordination (East 813226, North 818708) was recorded. The Contractor was advised to take corrective actions to the temporary arrangement of the perimeter silt curtain as soon as possible.

After investigation, there is no adequate information to conclude the recorded action level exceedances are related to this Contract. No 24-hr TSP Action and Limit Level exceedances were recorded on other monitoring date in the reporting month. All 1-Hour TSP results were below the Action and Limit Level in the reporting month.
