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 three 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¡±. In addition, Contract No. ¡°Provision of
Bus-Bus Interchange on Fanling Highway Kowloon Bound¡± was carried out within
the site boundary of Contract No. 02/HY/2015. This report focuses on Contract No. HY/2012/06 ¡°Widening of Fanling Highway ¨C Tai Hang to
Wo Hop Shek Interchange¡± in Stage
2 of the Project and ¡°Provision of
Bus-Bus Interchange on Fanling Highway Kowloon Bound¡± under Works Order Nos.
CB128520-5 and CB128519-0 in Contract No. 02/HY/2015 ¡°Highway Department Term
Contract (Management and Maintenance of Roads in Tai Po and North District
excluding High Speed Roads 2016-2022)¡±.
Pursuant to
the EP (EP-324/2008/E) 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 November 2017 and 31 January 2018. As informed by the Contractor,
construction activities of Contract No. HY/12012/06 in the reporting period
were as follows:
- Ground investigation
- Pipe laying
- Retaining wall construction
- Noise barrier
- Excavation
- Backfilling
- Drainage
- Footbridge demolition
- Bridge construction
-

Future Key Issues
Key issues to be
considered in the coming month include:
-
Properly
store and label oils and chemicals on site;
-
Chemical,
chemical waste and waste management;
-
Collection
of construction waste should be carried out regularly;
-
Properly
maintain all drainage facilities and wheel washing facilities on site;
-
Exposed
slopes should be covered up properly if no temporary work will be conducted;
-
Quieter
powered mechanical equipment should be used;
-
Suppress
dust generated from excavation activities and haul road traffic; and
-
Tree
protective measures for all retained trees should be well maintained.
