Results and Observations Sample Clauses

Results and Observations. 5.7.1 Dolphin surveys were conducted on 3, 5, 16 and 17 June 2014. A total of 220.1 km of transect line was conducted under favourable conditions. The total length travelled was also 220.1km, 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 June 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. 4.7.1 Impact water quality monitoring results and graphical presentations are provided in Appendix J. Note: S: Surface; and M: Mid-depth. 4.7.2 For water quality, one (1) action level and one (1) limit level exceedace were recorded at IS(Mf)9 and IS17 respectively on 5 December 2014 during mid ebb tide. No exceedance was recorded at all other monitoring stations in the reporting month. 4.7.2.1 Layout map below shows active works conducted on 5 December 2014 during ebb tide. 4.7.2.2 Exceedances recorded at IS17 and IS(Mf)9 during ebb tide are unlikely due to marine based construction activities of the Project because: 4.7.2.3 With refer to monitoring record, appearance of water was relatively more turbid at IS17 and IS(Mf)9 when compared with the appearance of water at IS(Mf)11, IS10, IS(Mf)16, IS7 and IS8 during monitoring at ebb tide on 05 December 2014. 4.7.2.4 However, with refer to the layout map attached, only public fill was being transferred as surcharge at near Portion A and since no marine filling was conducted during ebb tide on 5 December 2014, therefore, they are unlikely contribute to the exceedance of SS at IS17 and IS(Mf)9. 4.7.2.5 The location and type of active works conducted were almost the same on 5 and 8 December 2014 during ebb tide but no exceedance was recorded a IS17 and IS(Mf)9 on 8 December 2014. This indicates that the exceedances at monitoring station IS17 and IS(Mf)9 were unlikely to be contributed by active works. 4.7.2.6 In addition, with referred to monitoring record, no sediment plume has been observed to flow from the inside of the perimeter silt curtain to the outside of the perimeter silt curtain during ebb tide on 5 December 2014. (Please refer to photo record taken during ebb tide on 5 December 2015) 4.7.2.7 Photo record which shows the sea condition near Portion B, the southeast part of the HKBCF reclamation works at ebb tide on 5 December 2014. 4.7.2.8 Photo record which shows the sea condition near Portion E, the northeast part of the HKBCF reclamation works at ebb tide on 5 December 2014 4.7.2.9 Turbidity level recorded at IS17, IS(Mf)11, IS(Mf)16, IS(Mf)9, IS7 and IS8 on 5 December 2014 were below the action and limit level. This indicates the turbidity level at area near IS17 and IS(Mf)9 were not adversely affected. 4.7.2.10 The exceedances were likely due to local effects in the vicinity of IS17 and IS(Mf)9. 4.7.2.11 As such, the exceedances recorded at IS17 and IS(Mf)9 are unlikely to be project related. 4.7.2...

One (1) 24-hour TSP result exceeded the Limit Level on 08 April 2013 monitoring station AMS3A in the reporting month. 2.7.5 For the one (1) 24-hour TSP result exceeded the Limit Level on 8 April 13 at monitoring station AMS3A, according to information provided by the Contractor, land-based construction activity such as using canvas to cover sand material and stitching geotextile were being undertaken at Works Area WA2 during the monitoring period. 2.7.5.1 Functional checking on HVS at AMS3A was done. Air flow of the HVS was checked and the flow was steady during the 24-hr TSP sampling at AMS3A. The filter paper was re-weighted by the assigned HOKLAS laboratory and the result was reconfirmed. 2.7.5.2 As informed by the Contractor, construction activities like sheet piling and percussive piling, were carrying out by nearby private development project during the course of monitoring, which are close to the monitoring station AMS3A but beyond the site boundary of Works Area WA2. Traffics were observed passing exposed soil surfaces at those construction sites of nearby private development project. Please also see photo and layout map attached for reference of site conditions. 2.7.5.3 As refer to the wind data collected at wind station at Works Area WA2 during the monitoring period on 08 and 09 April 13 (as attached) East winds was prevailing during the monitoring period.
