No environmental non-compliance was found during the reporting period.
No environmental complaint was received during the reporting period. A statistical summary of environmental complaints since project commencement is presented in Annex D.
No summons was received in this reporting
period. A statistical summary of legal
proceeding since project commencement is presented in Annex D.
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 the 20th, 27th April 2006 and 4th, 12th May 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
·
No noticeable dust emission
was observed during the stockpile loading activity and vehicle movement within
the site, except during the site inspection on the 20th April 06 of
which dust emission during loading and concrete breaking activities were
observed. The Contractor was should
spray water regularly to the dusty activities;
·
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, except the above;
·
Earth mounds (surcharge) 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; and,
·
Hydroseedings were applied to the large stockpile and the landscape bunds
during the 12th May 06 site inspection.
Noise
·
No noisy activity was found
during the audit;
Water Quality
·
The capacity of the
sedimentation tank and site drainage system was found inadequate for treating
the wastewater generated on site after the heavy rainstorm, during the site
inspection on the 27th April 06.
The Contractor was reminded not to discharge the effluent which
contained high level of suspended solids as it would not comply with the
effluent discharge standard stated in the effluent discharge license. The Contractor re-constructed the site
drainage and wastewater treatment system with larger capacity during the 4th
May 06 site inspection;
·
Water pondings
were found after rainstorm during the site inspections on 27th April
and 4th May 06. The
Contractor should remove the water pondings soon
after the rainstorm;
·
The site hoarding near the
access road was sealed during the 12th May site inspection, to
prevent potential wastewater runoff during the rainy days in the wet season;
·
The wastewater generated
from the wheel-washing facility was reused ;
·
Manholes outside the site
were free of sand; and,
·
Chemical 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.
Waste Management
·
A Chemical Drum (with extracting equipment) was
found without drip tray and label near the seaside
during the site inspection on the 20th April 06. Surrounded soil was found contaminated. The Contractor should provide a drip tray for
the drum and clear up the contaminated soil as chemical waste. The drum was removed during the 27th
April site inspection;
·
Chemical waste drums were found without labels in
the chemical waste store near the seaside.
In addition, water was found accumulated in the drip tray of the waste
stores on site during the 27th April, 4th & 12th
May 06 site inspections. The Contractor was
reminded to provide labels for all the chemical waste containers and should
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. The chemical waste drums were labeled during
the 12th May site inspection; and,
·
Chemical (purple liquid) was found in a non-sealed
container on top of a chemical waste drum in the chemical waste store next to
the site office. The Contractor should
store all chemical waste properly and keep the chemical waste stores tidy.
Landscape and Visual
·
The transplanted trees at the new site were in good
and healthy conditions; and,
·
Hydroseeding was
applied to the landscape bunds at the edge of the site.
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.
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.
Air and Noise monitoring was not required for the project.
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 sampling has not yet conducted during the reporting period.
Auditing the Contractor’s Waste Management Plan (WMP) is part of the EM&A requirements. The Revision 1 of the WMP was submitted to EPD on 27th February 06. Comments regarding the above WMP were issued by EPD on the 27th March 06. The revised WMP (Revision 2) was certified by the ET and IEC, and submitted to the EPD on 3rd May 06.
As no dredging activity was conducted along the pipe trench during the reporting period, marine archaeological monitoring was not required.
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 the 12th May 06. The ET will review the plan.
The weekly site inspections included audits on landscape and visual issues to ensure that the site was in orderly acceptable manner.
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 the 24th April 06. The review of the submissions by ET and IEC is still in progress.
Weekly site inspection covered the waste management aspects which included measures to prevent land contamination by chemical wastes.
No dolphin monitoring was conducted as there was no piling or dredging activities implemented during the reporting period.
Key issues to be considered in the next one month will include:
· Wastewater discharge;
· Noise from operating machinery and equipment;
· Dust release and suppression.
Provided that environmental mitigation measures including good on-site practises are properly implemented, it is not expected that unacceptable adverse impact will arise.
Work programme for the next one month includes pile internal works (non-piling) and site works. Weekly site inspections will be undertaken.
