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 second 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 01 March 2015 to 31 May 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 AMS7A 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.

(a)       10 April 2015 (Log No. 001)

There was a complaint received by EPD and forwarded to Highways Department from the EPD by email on 10 April 2015 and then forwarded through the R.E. (AECOM) to the Contractor of Contract No. HY/2013/02 (China Harbour) and then the ET (ETS-Testconsult Ltd.) on 15 April 2015. The above mentioned complaint follow-up inspection was performed by the ET of Contract No. HY/2013/02 on 16 April 2015.The complaint investigation report (Log No. 001) was issued by the ET of Contract No. HY/2013/02 and verified by the IEC/ENPO on 21 April 2015.The complainant complained that he was disturbed by noise from construction activities of HZMB Project during weekends and holidays. According to the inspection, since no abnormal construction works was carried out and all construction equipment was operated in accordance with the condition(s) under the valid CNP No. GW-RS0128-15 for the works of Contract No. HY/2013/02 during the holiday period (03 to 07 April 2015) and all data of the weekly noise levels measured at the monitoring stations (NMS2 and NMS3B) by the ET of Contract No. HY/2010/02 on 08 and 13 April 2015 were found satisfactory without exceedance of the limit level, this reveals that the Contractor of Contract No. HY/2013/02 has implemented suitable mitigation measures to reduce the noise impact during the construction works. The complaint was found non-related to Contract No. HY/2013/02.

 

(b)      21 May 2015 (Log No. 002)

There was a complaint received by EPD from a public via EPD’s hotline on 21 May 2015 and was forwarded by EPD to Highways Department and then the ENPO on 22 May 2015. Then the ENPO forwarded the complaint by email to the R.E. (AECOM), the Contractor (China Harbour) and the ET (ETS-Testconsult Ltd.) of Contract No. HY/2013/02 on 22 May 2015. The above mentioned complaint follow-up inspection was performed by the ET of Contract No. HY/2013/02 on 23 May 2015.The complaint investigation report (Log No. 002) was issued by the ET of Contract No. HY/2013/02 and verified by the IEC/ENPO on 2 June 2015. The complainant complained that noise generation and dark smoke emission produced from plants undertaking at night-time works at HKBCF Project. According to the investigation, the construction works of the Contractor of Contract No. HY/2013/02 during 18 May 2015 to 23 May 2015 was carried out from 08:00 to 18:00 and no any works and PME operation were undertaken at night-time. The complaint was found non-related to Contract No. HY/2013/02.

 

Although the above mentioned two complaints were non-related to Contract No. HY/2013/02, the Contractor of Contract No. HY/2013/02 was reminded to provide appropriate noise and smoke mitigation measures, such as switched off vehicles and equipment while not in use, scheduled the construction works to minimize noise nuisance and well-maintained plant operated on-site to minimize noise nuisance and dark smoke emission produced etc

 

4.2.2  There were no notifications of summons or prosecutions received during the reporting period.

 

4.2.3 Statistics on environmental complaints, notifications of summons and successful prosecutions are summarized in Appendix I.
