5.1 Environmental monitoring of air quality (1-hr TSP and 24-hr TSP) for the Project was performed in October 2007. There was no exceedance of 1-hour and 24-hour TSP monitoring recorded in the reporting month.
5.2 Environmental site inspections were conducted 4 times in the reporting month. Due to the dry weather conditions, fugitive dust was occasionally observed during dumping and manual sorting of non-inert waste and during vehicle movement along the haul road in Area A. Improving the water spraying at the non-inert waste stockpile and to provide longer water spraying time to the load of the trucks at the weigh-bridge in Area B1 in order to maintain the load damp prior dumping in Area A
5.3 No environmental complaint, prosecutions or notifications of summons were received in October 2007.
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;
· Undertake water spraying on stockpiling area by water bowers;
· 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
· Remove the stagnant water or provide pesticide for the stagnant water in the permanent desilting chambers, if any.
Chemical and Waste Management
· Remove waste materials from site regularly to avoid accumulation;
· Handle and store chemical wastes properly;
· Remove unwanted material in the existing stockpiles and avoid further dumping of such material;
· Provide and maintain sufficient drip trays for diesel drums, chemical containers, chemical waste storage drums and diesel operated generator set;
· Maintain good housekeeping at the workshop area;
· Ensure sufficient tarpaulin sheets are provided to cover drip trays;
· Avoid soil being polluted during oil filling and equipment maintenance; hence, properly remove and store the contaminated soil, if any, and
· Provide a proper chemical waste store.
Landscape and Visual
· Erect all the site hoardings/chaining fences in accordance with agreed design at proper location.
