This report documents the findings of EM&A works conducted in the
quarter between 1 May 2020 and 31 July 2020.
The impact stage EM&A programme for the Project includes air quality
and noise monitoring.
The EM&A programme was carried out by the ET in accordance with the
EM&A Manual requirements. It is
concluded from the environmental monitoring and audit works that adequate
environmental mitigation measures have been implemented by the civil works
contractors where appropriate in the reporting quarter.
In the reporting quarter, no exceedance event was recorded. No necessary
remedial actions have been taken.
No environmental
non-compliance was recorded in the reporting
quarter. No environmental complaint was received in
the reporting quarter. No
environmental related prosecution or notification of summons was received in
the reporting quarter.
The box culvert works have been partially
completed by the end of March 2014 except the last construction activity,
installation of a base slab at Box Culvert ID4. The installation of the base
slab at Box Culvert ID4 was commenced in December 2016 and has been completed
in March 2017.
The 4-week post construction water quality
monitoring has been commenced and completed in April 2017.
As informed by the contractor, all major construction activities of the
Entrusted Portion Project of Section 1A and 1B were substantially completed on
28 September 2018 and 3 October 2018 respectively. In such regard, the EM&A
Programme of the captioned project, including monthly EM&A reporting and
the corresponding environmental monitoring and audit works, is no longer
required and we have submitted the termination proposal to EPD on 4 April 2018.
And EPD replied the Final EM&A Report need to be provided to facilitate the
consideration of cessation of construction phase EM&A Programme and the
EM&A monitoring and audit works will not be terminated without prior
approval of EPD.
1.1.1 The Project is a Designated Project under the Environmental Impact Assessment Ordinance (EIAO) (Cap. 499). An Environmental Impact Assessment (EIA) Report together with an Environmental Monitoring and Audit (EM&A) Manual were approved on 14 July 2000 (Register Number: EIA-043/2000). The Project is governed by an Environmental Permit (EP) (EP-324/2008) which was granted on 23 December 2008. A variation of EP (VEP) was applied and the VEP (EP-324/2008/A) was subsequently granted on 31 January 2012. An additional VEP has been applied on 24 February 2014 and the VEP (EP-324/2008/B) was subsequently granted on 17 March 2014. Furthermore, an additional VEP has been applied on 9 March 2015 and the VEP (EP-324/2008/C) was subsequently granted on 27 March 2015. The previous VEP (EP-324/2008/D) was granted on 27 August 2015. The current VEP (EP-324/2008/E) was granted on 26 January 2017.
