3                                            Environmental Issues and Actions

3.1                                      Previous Environmental Deficiencies and Follow-up Actions

As no environmental complaint was received over the last reporting period, no follow-up action was required.

Weekly site inspections were carried out by the ET on 16th, 23rd, 30th June and 7th, 14th July 2006.Overall, the site was in good orderly manner and no non-compliance was found.Environmental deficiencies and follow-up actions/mitigation measures were identified during the inspections, as follows:

Air Quality

            Dust emission, caused by vehicle movement within the site was observed during 14th July site inspection.Although water tanker was used, the Contractor should increase the water spraying frequency on a dry and windy day.No noticeable dust emission was observed during the stockpile loading activity and vehicle movement during other site inspections;

            Unpaved road appeared to be regularly wetted during the dry days.The site in general was also regularly wetted with water sprayed to the dust generating activities;

            Earth mounds and large stockpiles were covered to avoid dust emission;

            Site entrance/exit was paved and wheel-washing facility was provided at the site exit to avoid dust deposit in the access road;

            Main access road within the site (between site office and exit) was paved to avoid dust emission.Other sections of the major access road in the construction area were paved with stones; and,

            Hydro-seed was applied to the large stockpile and the landscape bunds.Hydro-seed will be applied to the new section of the large stockpile.

Noise

            No noisy activity was found during the audit; and,

            An air compressor at the Workshop was operated without noise label.The Contractor was reminded to provide noise labels for all air compressors before they can be used.

 

Water Quality

            Water pondings were found after rainstorm during the site inspections on 16th, 30th June and 7th July 06.The Contractor should remove the water pondings soon after the rainstorm;

            Water was found accumulated in the constructed sump pit during the site inspection on 14th July 06.The Contractor should either remove the water in the pit or to spray the water ponding with mosquito oil regularly;

            The wastewater generated from the wheel-washing facility was reused.However, the wastewater from the wheel-washing facility was seen flooded onto the road surface causing water ponding during 16th June site inspection.The Contractor should clear the flooded water and control the flooding;

            Manholes outside the site were free of sand;

            Site toilets were provided on site.Septic tank was installed to treat the sewerage from the site toilets.No sewerage effluent discharge out of the site was made; and,

            For the wastewater generated from the site canteen, a tank/pit was installed to contain all wastewater generated from the canteen.The wastewater was collected by licensed operator regularly.

Waste Management

            A bucket filled with brownish muddy water (probably the wastewater removed from the drip tray of the generator) was found in the chemical waste store near the site office during 30th June site inspection.The bucket had no label and not sealed.The Contractor should ensure that all chemical waste should be stored properly in the chemical waste containers with proper labeling.In addition, water was found accumulated in the drip trays of the chemical waste stores on site during 30th June, 7th and 14th July 06 site inspections.The Contractor was reminded to ensure that the drip trays are free of water/chemical waste.If the water within the drip tray appeared contaminated, such should be treated as chemical waste for disposal.As water was found accumulated in the drip trays of the chemical waste stores during several site inspections, the ET recommended the Contractor to use metal doors instead of curtain/screen that are currently using, to prevent rainwater dripping into the stores.The Contractor replied that they will consider installing metal doors for the chemical waste stores; and,

            A stand-alone chemical drum (probably diesel oil for the air compressor) without drip tray was found standing in the water ponding next to the air compressor next to the operational building area during 7th July site inspection.The Contractor should provide drip trays to contain all chemical drums on site, which should also be located away from water ponding area;

Landscape and Visual

            The transplanted trees at the new site were in good and healthy conditions; and,

            Grass appeared to grow well at the landscaping bund.

Overall, the site was in a good orderly manner.Suitable mitigation measures, such as the use of water truck regularly and tarpaulin covers should continuous be used to ensure dust emission is avoided on site.

The ET will keep track on the EM&A programme to ensure compliance of environmental requirements and the proper implementation of all necessary mitigation measures.

3.2                                      Implementation Status on Environmental Protection Requirements

The implementation status of environmental mitigation measures and requirements as stated in the EIA Report, Environmental Permits and EM&A Manual during the reporting period is summarized in Annex C.

3.3                                      Environmental Monitoring

3.3.1                                Air and Noise

Air and Noise monitoring was not required for the project.

3.3.2                                Water Quality

Water quality monitoring at the monitoring stations was not required as no dredging activity was taken place.

According to the wastewater discharge license (industrial trade effluent) issued by the EPD on 15th March 06, the Contractor is required to conduct grab sampling/analysis on SS at the discharge point(s) quarterly.The Contractor indicated that the sampling was conducted in mid July.

3.3.3                                Waste Management

The Contractorís revised WMP (Revision 2) was certified by the ET and IEC, and submitted to the EPD on 3rd May 06.

3.3.4                                Cultural Heritage

As no dredging activity was conducted along the pipe trench during the reporting period, marine archaeological monitoring was not required.

3.3.5                                Landscape and Visual

According to the EIA report and EM&A manual, mitigation measures and site inspection are required during the landscaping/planting works. Hydroseeding of landscape bunds was conducted on site during the reporting period. The transplanted trees were in good and healthy conditions.

The final version of landscaping plan was received by the ET on 12th May 06.The ET and IEC have reviewed the plan and comments were issued.The revised Final Landscape Plan was submitted to EPD on 5th July 06.

The weekly site inspections included audits on landscape and visual issues to ensure that the site was in orderly acceptable manner.

3.3.6                                Land Contamination, Hazard to Life and Fuel Spill Risk

According to the EIA report and EM&A manual, mitigation measures and design phase audit are required to minimise the risk of fuel spill and hazards.

The Contractor submitted the Environmental Designs for the tank farm and fuel pipelines to the ET on 24th April 06. The ET and IEC have reviewed the designs and comments were issued to the Contractor.The revised designs were submitted to EPD on 5th July 06.

Weekly site inspection covered the waste management aspects which included measures to prevent land contamination by chemical wastes.

3.3.7                                Ecology

Dolphin Visual Monitoring

No dolphin monitoring was conducted as there was no piling or dredging activities implemented during the reporting period.

 

4                                            Future Key Issues

4.1                                      Key Issues for the Next One Month

Key issues to be considered in the next one month will include:

 

       Noise from operating machinery and equipment;

 

       Dust release and suppression.

4.2                                      Impact Prediction for the Next One Month

Provided that environmental mitigation measures including good on-site practises are properly implemented, it is not expected that unacceptable adverse impact will arise.

4.3                                      Works and Monitoring Schedule for the Next One Month

Work programme for the next one month includes pile internal works (non-piling) and site works. Weekly site inspections will be undertaken.††
