Introduction
This is the fifty-third monthly Environmental Monitoring and Audit (EM&A) report prepared by Maunsell Environmental Management Consultants Limited (MEMCL) for the “Castle Peak Road Improvement between Ting Kau and Sham Tseng, Tsuen Wan” (The Project). This report documented the findings of EM&A Works conducted during the impact period in November 2006.
The construction works had
commenced since July 2002. The Contractor implemented most of the environmental
mitigation measures and effectively minimised the impacts arising from the
construction activities.
The IC(E) verified Marine Water
Quality Baseline Monitoring Report (Rev.2) had been submitted to the EPD on 24
July 2003. Comments were received from EPD on 27 August 2003. Response to
comments was verified by IC(E) via e-mail communication. Revised pages were
issued to the Contractor on 1 September 2003 for their onward submission to
EPD, AFCD, ER and IC(E).
The contract has been
substantially completed on 31 July 2006. The Contractor only carried out
landscape works, remaining road paving and utilities installation in the
reporting month. Remaining marine works has not yet commenced in the reporting
month.
Environmental Monitoring Works
Air Quality
The 1-hour and 24-hour TSP
monitoring had been ceased from 1 November 2006 due to the completion of major
construction works. The approval letters from the engineers and the IEC for the
cessation of monitoring programme is provided in Appendix M.
Construction Noise
The construction phase impact
noise monitoring had been ceased from 1 November 2006 due to the completion of
major construction works. The approval letters from the engineers and the IEC
for the cessation of monitoring programme is provided in Appendix M.
Operational noise monitoring was not carried out in the reporting month.
Water Quality
In the reporting month, thirteen
sessions of water quality monitoring were conducted. A total of 31 action and
26 limit level exceedances were recorded. As no marine works were conducted at
the Reclamation Site in the reporting month, the exceedances were considered
not associated to the Project.
Landscape and Visual
The construction phase landscape and
visual audit had been ceased from 1 November 2006 due to the completion of
major construction works. The approval letters from the engineers and the IEC
for the cessation of landscape and visual audit programme is provided in
Appendix M. Establishment period landscape and visual audit will be carried out
bimonthly and the next audit is scheduled to December 2006.
Complaints, Non-compliance and
Prosecutions
No environmental complaint, non-compliance or prosecution was received in the reporting month.
Permits and Licences
No
new environmental permit and licence was applied or obtained in the reporting
month.
Environmental Site Inspection
Site inspection was carried out by the Environmental Team to ensure proper implementation of environmental mitigation measures specified in the EM&A Manual and compliance with relevant environmental legislation.
As there were no marine works,
the water quality impact was minimal from the reclamation area in the reporting
month. The Contractor was requested to clear the C&D waste along the shore
for disposal.
Future Key Issues
General refuse and C&D waste should be collected properly. The Contractor was advised to maintain on-site sorting of inert and non-inert construction waste. Non-inert construction waste should be timely collected for off-site disposal.
Drainage system inside the site should
be properly maintained and during the marine works, proper coverage to
stockpiles during rainfall, maintain sufficient and utilize wastewater
treatment facilities in works area to prevent any muddy discharge.
