5.     CONCLUSIONS AND RECOMMENDATIONS

 

Conclusions

 

5.1               Environmental monitoring of air quality (1-hr TSP and 24-hr TSP) for the Project was performed in April 2008. There was no exceedance of 1-hour and 24-hour TSP monitoring recorded in the reporting month.

 

5.2               Environmental site inspections were conducted 5 times in the reporting month. Minor fugitive dust was occasionally observed during vehicle movement along the haul road in Area B2 near the access bridge. The Contractor was reminded to provide water spraying at the area, particularly during sunny and dry weather The Contractor was also reminded to properly maintain the plants on site to prevent any oil leakage.

 

5.3               No environmental complaint, non-compliance or prosecutions or notifications of summons were received in the reporting month.

 

Recommendations

 

5.4               According to the environmental site inspections performed in the reporting month, the following recommendations were provided:

 

Air Quality

 

·         Ensure the frequency of water spraying on haul roads, unloading areas and stockpiles to be sufficient to suppress the dust sources;

·         Provide proper maintenance for the powered mechanical equipment and barges to avoid emission of dark smoke;

·         Provide water spraying onto the truckloads during inspection of fill material;

·         Conduct road sweeping on the public road and the main haul roads outside and near the site egress by the road sweeper;

·         Erect adequate speed limit signs to advise the truck drivers of the speed limit;

·         Operate mist spraying systems and automatic water sprinklers in the temporary CWSF;

·         Implement the dust mitigation measures for the construction activities;

·         Designate proper haul roads to ensure effective water spraying; and

·         Ensure all vehicles to be washed before leaving the site egress by provision, operation and maintenance of automatic wheel washing facilities.

 

Construction Noise

 

·         Conduct noisy activities at a farther location from the NSR.

 

Water Quality

 

·         Maintain the drainage system, including the trapezoidal channels;

·         Operate and maintain the treatment system for the site toilet; and
