The proposed widening of Tolo Highway and Fanling Highway
between Island House Interchange and Fanling (the
Project) is a Designated Project under the Environmental Impact Assessment
Ordinance (Cap. 499) (EIAO). An Environmental Impact Assessment (EIA) Report
(the approved EIA Report) together with an Environmental Monitoring and Audit
(EM&A) Manual (the approved EM&A Manual) were completed and approved
under the EIAO on 14 July 2000 (Register Number: EIA-043/2000).
The objective of the Project ¡°Widening of Tolo
Highway / Fanling Highway between Island House
Interchange and Fanling¡± is to widen Tolo Highway and Fanling Highway
to dual 4-lane carriageway in order to alleviate the current traffic congestion
problems and to cope with the increasing transport demands to and from the
urban areas and also cross boundary traffic.
The construction works for this Project will be delivered in 2 stages
i.e. Stage 1 (between Island House Interchange and Tai Hang) and Stage 2
(between Tai Hang and Wo Hop Shek Interchange). Stage 2 would be implemented under two
works contracts. Contract No. HY2012/06 ¡°Widening of Fanling Highway ¨C
Tai Hang to Wo Hop Shek Interchange¡± and the
entrusted portion to CEDD under Contract No. CV/2012/09
¡±Liantang/Heung Yuen Wai Boundary Control
Point Site Formation and Infrastructure Works ¨C Contract 3¡±. This
report focuses on
Contract No. HY2012/06 ¡°Widening of Fanling Highway ¨C Tai Hang to Wo Hop Shek Interchange¡± in Stage 2 of
the Project only.
Pursuant
to the EP (EP-324/2008/A) Condition 2.7, the Capture Survey Trip Report for Ma Wat River Northern Meander (Version 2) for the Project was
submitted on 24 December 2013 by the Environmental Team (ET) and verified by
the Independent Environmental Checker (IEC) on 6 January 2014.
The
construction phase of the Contract under the EP and the Environmental
Monitoring and Audit (EM&A) programme of the contract commenced on 21 November 2013. The impact
environmental monitoring and audit includes air quality and noise monitoring.
This report documents the findings of EM&A works conducted in the period between 1 May 2014 to 31 July 2014. As informed by the Contractor, construction activities in the reporting period were:-
- Ground investigation;
- Tree felling and transplantation;
- Piling works;
- Pipe laying;
- Retaining wall construction;
- Excavation;
- Backfilling; and
- Drainage.
There was no reporting change
required in the reporting month.
Breaches of Action and Limit Levels for Air
Quality
No exceedance of Action and Limit Level was recorded for
1-hour and 24-hour TSP monitoring in the reporting month.
Breaches of Action and Limit Levels for Noise
No Action Level exceedance of construction
noise was recorded in the reporting period since no noise complaints related to
0700 ¨C 1900 hours on normal weekdays were received. Two (2) Limit Level exceedances were recorded on 12 and 18 June 2014
respectively for noise monitoring at M3 in the reporting period. The exceedances were considered non-project-related. The
details of exceedance are given in Appendix M of the
Monthly EM&A Report of June 2014.
