This Quarterly Environmental Monitoring and Audit (EM&A) Report is prepared for Contract
HY/2013/02 Hong Kong–Zhuhai-Macao Bridge Hong Kong Boundary Crossing Facilities
(HKBCF) – Infrastructure Works Stage I (Western Portion) (hereafter referred to
as “the Contract”) for the Highways Department of Hong Kong Special
Administrative Region (HKSAR). The Contract was awarded to China Harbour
Engineering Co., Ltd. (hereafter referred to as “the Contractor”) and ETS-Testconsult
Limited was appointed as the Environmental Team (ET) by the Contractor.
The
Contract is part of Hong Kong – Zhuhai – Macao Bridge HKBCF which is a
“Designated Project”, under Schedule 2 of the Environmental Impact Assessment
Ordinance (EIAO) (Cap 499) and Environmental Impact Assessment (EIA) Report
(Register No. AEIAR-145/2009) was prepared for the Project. The
current Environmental Permit (EP) No. EP-353/2009/H for HKBCF was issued
on 19 January 2015. These documents are available through the EIA Ordinance Register.
Site preparation works of the Contract was started on 25 July 2014 and the
construction works of the Contract commenced on 24 November 2014.
ETS-Testconsult Limited has been appointed by the Contractor to
implement the Environmental Monitoring & Audit (EM&A) programme for the
Contract in accordance with the Updated EM&A Manual for HKBCF (Version 1.0)
and provide environmental team services to the Contract.
This is the first Quarterly Environmental Monitoring and
Audit (EM&A) Report for the Contract which summaries findings of the EM&A
works conducted during the reporting period from 24 November
2014
to 28 February 2015.
Environmental Monitoring and
Audit Progress
The EM&A programme was undertaken in accordance with the Updated EM&A
Manual for HKBCF (Version 1.0). It should be noted that the air quality and
noise monitoring works for the Contract are covered by Contract No. HY/2010/02 Hong Kong-Zhuhai-Macao Bridge HKBCF – Reclamation Works
and Contract No. HY/2011/03 Hong Kong-Zhuhai-Macao Bridge Hong Kong Link
Road – Section between Scenic Hill and HKBCF. The ET of the Contract or another
ET of the HZMB project is required to conduct impact air quality monitoring at
AMS6 and AMS7 (replaced by AMS7A from 05 February 2015) and noise monitoring at
NMS2 and NMS3B as part of EM&A programme if these monitoring stations are
no longer covered under Contract No. HY/2010/02 and
HY/2011/03. However, this is subject to ENPO’s final decision on which
ET should carry out the monitoring works at these stations.
The dates of environmental site
inspections during the reporting period are listed below:
