3.1 Environmental Site Inspections
Environmental site inspections are required to inspect the construction activities of the Development of EcoPark in order to ensure that appropriate environmental protection and pollution control mitigation measures are properly implemented.
Site inspections were conducted on 5, 11, 19 and 27 December 2007.
A detailed checklist of each site
inspection together with comments, relevant photos and maps have been filed and
kept.
The findings and results of site inspections are provided in Table 3.1:

3.2 Air Dust
Water spraying by water truck on site area such as Road A, Road C, Road D, Road F and unpaved site area beside marine front for dust mitigation was observed.
Excavation work at Road F near site office was finished and the site exit at Road F was closed. The site exit at Road A remained and manual wheel washing was used.
3.3 Noise
The major noise source was vehicle movement, machinery and rock
excavation in the EcoPark. Since the nearby NSRs were remote, the noise impact
was minimal. There was no specific observation noted regarding noise issue. The
Contractor has obtained the Construction Noise Permit on 07 August 2007.
3.4 Surface Water Quality
Since there was no water discharge at manhole, the Contractor removed the silt curtain installed at discharge point on 4 April 2007, as agreed by the Engineer¡¦s Representative. No muddy water was observed at discharge point.
Chemical toilets (3 nos.) have been provided by a licensed contractor, of which sewage generated is collected every three to five days without causing contamination on surface water. The Effluent Discharge Licence was issued to the Contractor on 20 November 2006.
The temporary storage tank was used to store the effluent of aerobic wastewater treatment system and the stored effluent was pumped away regularly. As checked by the ET, there was no effluent discharge into the stormwater drain.
3.5 Visual and Landscape Impact
Hoarding was erected at the site egress and aligned along the site boundary along Lung Mun Road. Hoardings were specially designed to be movable for future re-use in other locations.
During site clearance, trees were relocated to be replanted for landscaping in the future in EcoPark.
3.6 Waste / Chemical Waste
Waste was found in site area beside Site Entrance. The Contractor rectified by removing waste for better house keeping.
Waste was found in site area beside Administration Building. The Contractor rectified by removing waste for better house keeping.
Inadequate refuse collection bins in Administration Building was observed. The Contractor rectified by establishing more refuse collection bins in Administration Building for better house keeping.
Accumulated water was found at the bottom of oil and chemical waste storage cabinet. The Contractor was reminded to remove accumulated water.
The Contractor implemented visual inspection and distributed flyers/ notices to ensure all dump trucks have mechanical covers closed when leaving EcoPark site.
Separate waste collection bins were made available for
collecting aluminum cans, waste paper and plastic bottles etc. The Contractor
has provided the revised site layout plan for refuse collection points as shown
in Appendix 3.
Waste dumpers were used for the collection and storage of general
waste. Temporary storage areas for waste metals and waste tyres were
established.
The Contractor has provided sufficient drip trays for all temporary electricity generators at site. These drip trays should be covered by tarpaulin sheet to minimize rainfall accumulation.
Excavated materials are reused as back-fill material to balance cut
and fill and hence reduce the generation of materials. Surplus materials are
returned to stock in centralized area with suitable protective measures. The
Contractor was reminded to comply with the requirements and conditions for
disposal at public fill facility and all oversized aggregates should be crushed
to less than 250mm before delivering to the public fill.
Materials are recycled and re-used at site as much as practicable to minimize waste generation. Timbers are recycled to make temporary tools and assess ladders etc. Excavated rocks, concrete and asphalts are stored for future re-use in land formation and structural construction etc.
Registered waste collectors will be
arranged to collect and transport the wastes whenever necessary.
Table 3.4 provides a summary table of waste disposal in December 2007. The Contractor has been reminded to keep good record at site in order to have a clear presentation of waste disposal.
