4.                  Environmental Complaint and Non-Compliance

4.1              Environmental Exceedances

In February 2007 and April 2007:

No exceedances in 1-hour and 24-hours TSP was recorded at the City Hall monitoring station during the reporting period.

Noise exceedances were recorded on the 9 and 19 February 2007 at the City Hall monitoring station. On 9 February 2007, the noise exceedance was caused by ground works involving hand-held breakers carried out by EMSD in front of the city hall. On 19 February 2007, there were no construction activities carried out at CR3 during the Chinese New Year holiday and hence the exceendance was not works related.

Exceedances of the LL for DO were observed on the 16-Apr 2007. All exceedances observed were not expected to have been directly related to project works as no marine works nor run-off from the site were observed during the days. The exceedances could be attributed to natural variation in ambient conditions rather than the project works.

Exceedances of the AL for SS were observed at M1A (on 23-Feb 2007), M6 (on 21-Mar 2007), M10 (on 16-Apr 2007) and M12 (on 5-Mar 2007). 

 

4.2              Non-Compliance

4.3              Summary of Actions Taken by the Contractor

The Contractor has implemented the following measures to prevent air and water quality impacts:

·         Contractor has implemented their Drainage Management Plan to Control Site Run-off for the wet season – actions completed and underway include: repair and improvement of existing bunds/sandbags on the edge of the reclamation; installation of additional bunds; compaction of soil surface and pathing where possible to prevent erosion, creation of drainage channels and soak pits. 

·         Provision a single WetSep flocculation based water treatment plant and additional settlement tanks to remove suspended solids from discharge waters;

·         Provision of catch pits to collect spill over from wheel washing facilities; increased frequency of cleaning of catch-pits;

·         Water browsing of haul roads and other areas of the site and covering of stockpiles.


4.4              Environmental Enquiries

5.                  Conclusion

During the environmental site inspections conducted within the reporting quarter, no non-compliances were noted and no prosecutions were received during the reporting quarter.

No exceedances in 1-hour and 24-hours TSP were recorded at the City Hall monitoring station during the reporting period.

Noise exceedances were recorded on the 9 and 19 February 2007 at the City Hall monitoring station. On 9 February 2007, the noise exceedance was caused by ground works involving hand-held breakers carried out by EMSD in front of the city hall. On 19 February 2007, there were no construction activities carried out at CR3 during the Chinese New Year holiday and hence the exceendance was not works related.

Exceedances of the AL for DO were observed on the 14, 23, 26-Feb 2007, 7, 9, 16, 19, 26, 28, 30-Mar 2007, 2, 6, 9, 11, 13, 16, 18, 20, 23, 25, 27 and 30-Apr 2007. Exceedances of the LL for DO were observed on the 16-Apr 2007. All exceedances observed were not expected to have been directly related to project works as no marine works nor run-off from the site were observed during the days. The exceedances could be attributed to natural variation in ambient conditions rather than the project works.

Exceedances of the SS were observed at M1A (on 23-Feb 2007), M6 (on 21-Mar 2007), M10 (on 16-Apr 2007) and M12 (on 5-Mar 2007).  All exceedances were not considered to have been related to project works.
