An ICC complaint (Case Ref: 2-4495970766, lodged at 0955hrs on 12 March 2018) was referred to the ET on 27 March 2018. The ICC hotline operator reported that a public complaint was referred by the Police Force regarding noise emanation from road construction works at North Point section Island East Corridor (IEC) near 19 Wharf Road at around 0920hrs on 12 March 2018. Further information regarding the same event was received via ICC hotline (Case ref: 2-449606553, lodged at 1004hrs on 12 March 2018) was referred to the ET on 27 March 2018. The complainant further reported that noise was emanated from road construction works on Island Eastern Corridor (IEC) near Yu Lee Mo Fan Memorial School. Temporary noise barrier observed to be transparent in nature was speculated to be ineffective; and it was observed that only 3 out of the 6 units of temporary noise barrier are installed. The complainant suggested that additional 6 sections of noise barrier shall be installed. The noise emanation was started from 0800hrs and he is a resident at 18 Wharf Road and his rest was adversely affected by the concerned noise emanation. He has contacted the Environmental Protection Department and the Police Force regarding the noise emanation. The Environmental Protection Department has replied that construction works conducted after 0700hrs does not violate statutory requirement while the Police Force has created an ICC complaint case file (2-4495970766) for follow up.

ET confirmed with the Resident Site Staff that Concrete breaking works on IEC Eastbound near Pier F8 and Pier F9 was conducted under Contract HY/2009/19 from 0900hrs to 1000hrs on 12 March 2018. Noise mitigation measure including wrapping of breaking head with acoustic material was implemented. Enhancement measures including provision of 2.5m high temporary noise barrier were subsequent implemented on 12 March 2018.

According to RSS confirmed information, concrete breaking works on IEC Eastbound near Pier F8 and Pier F9 was conducted under Contract HY/2009/19 from 0900hrs to 1000hrs on 12 March 2018. Noise mitigation measure including wrapping of breaking head with acoustic material was implemented. Enhancement measures including provision of 2.5m high temporary noise barrier were subsequent implemented on 12 March 2018.

Based on review on relevant site record, noise impact associated with the breaking works on IECL opposite to the concerned location was observed across March 2018 and project related exceedances were recorded at nearby noise monitoring station at YLMF Memorial School across March 2018. Upon identificaion of the project related exceedance at YLMF memorial school noise monitoring station, the Contractor is requested to adopt remedial and enhancement measures to minimize the noise emanation and avoid noise impact to the nearby sensitive receivers.

According to ET follow up checking, the following enahncement measures were proposed and implemented by the Contractor by 16 March 2018 including provide additional temporary noise barrier and repair damaged or incomplete temporary noise barrier installed for the breaking works, provide additional acoustics screen to the breaking tip in addition to temporary noise barrier installed, provide covering of breaker tip with acoustic material for noise reduction and conduct breaking works intermittently.

Nevertheless, subsequent to 16 March 2018, it was observed at times that the above mitigation measures were not fully implemented by the Contractor throughout the remaining breaking works period. Upon identification of deficiency in mitigation measures, the Contractor has been requested to rectify any deficiency obserbed and ensure relevant noise mitigation measures are implemented and the observed deficiencies are rectified prior to resumption of the concerned impact associated works. According to Contractor information, the concerned breaking works have been completed by 26 March 2018.

In view of the public concern and the identified noise concern, the Contractor of HY/2009/19 was reminded that, shall future breaking works be required to be conducted on IECL (at works area located at the East of the noise enclosure), noise mitigation measure including but not limit to provision of temporary noise barrier with adequate height and extend and additional noise screen shall be proposed for ET/IEC review and confirmation prior to conducting the corresponding works to minimize the potential impact to the surroundings. The Contractor is also advised to review the adopt construction method with consideration on alterative PME with reduced noise emanation to minimize the potential noise impact to the surroundings.

2 Project Background

2.1 Background

2.1.1. “Wan Chai Development phase II and Central-Wan Chai Bypass” and “Central-Wan Chai Bypass and Island Eastern Corridor Link” (hereafter called “the Project”) are Designated Project (DP) under the Environmental Impact Assessment Ordinance (Cap. 499) (EIAO). The Environmental Impact Assessment (EIA) Reports for Central-Wan Chai Bypass and Island Eastern Corridor Link (Register No. AEIAR-041/2001) and Wan Chai Development phase II and Central-Wan Chai Bypass (Register No.: AEIAR-125/2008) have been approved on 31 August 2001 and 11 December 2008 respectively.

2.1.2. The key purpose of Wan Chai Development Phase II (WDII) is to provide land at Wan Chai North and North Point for construction of the Central-Wan Chai Bypass and Island Eastern Corridor Link (CWB). Land formed under the project will be developed as a world-class waterfront promenade joining that at the new Central waterfront for public enjoyment.

2.1.3. There is a compelling and present need for the CWB to provide relief to the very congested east-west Connaught Road Central/Harcourt Road / Gloucester Road Corridor (the Corridor) which is currently operating beyond its capacity. The CWB will provide relief to the existing congestion along the Corridor and cater for the anticipated growth of traffic on Hong Kong Island. Without the CWB and its access roads, there will not be sufficient capacity to serve the heavy traffic demands at both strategic and local levels.

2.2 Scope of the Project and Site Description

2.2.1. Design and Construction of Central – Wan Chai Bypass and Island Eastern Corridor Link under the Project involves the construction and operation of a trunk road and its road tunnel more than 800m in length between portals that is shown at Figure 2.1.

2.2.2. The study area encompasses existing developments from Central to North Point. The scope of the Central-Wanchai Bypass (CWB) and Island Eastern Corridor Link (IECL) includes:

· A dual three-lane trunk road, approximately 4.5 km in length, and tunnel approximately 3.7 km in length defined from the connection with the existing Rumsey Street Flyover in Central, through to a connection with the existing Island Eastern Corridor to the east of the Causeway Bay Typhoon Shelter (CBTS);

· The Central Interchange near the Rumsey Street Flyover to provide road connections to the Central area;

· Tunnel control buildings and ventilation buildings;

· Slip roads to connect the CWB to the local road system in the Wan Chai North and Causeway Bay area;

· Associated road lighting, road signing, traffic control and surveillance system; and

· Other associated works.

2.2.3. The project also contains various Schedule 2 DPs that, under the EIAO, require Environmental Permits (EPs) to be granted by the DEP before they may be either constructed or operated. Table 2.1 summarises the five individual DPs under this Project. Figure 2.1 shows the locations of these Schedule 2 DPs.

9 Complaints, Notification of Summons and Prosecution

9.0.1. One environmental complaint was received in the reporting period.

9.0.2. An ICC complaint (Case Ref: 2-4495970766, lodged at 0955hrs on 12 March 2018) was referred to the ET on 27 March 2018. The ICC hotline operator reported that a public complaint was referred by the Police Force regarding noise emanation from road construction works at North Point section Island East Corridor (IEC) near 19 Wharf Road at around 0920hrs on 12 March 2018. Further information regarding the same event was received via ICC hotline (Case ref: 2-449606553, lodged at 1004hrs on 12 March 2018) was referred to the ET on 27 March 2018. The complainant further reported that noise was emanated from road construction works on Island Eastern Corridor (IEC) near Yu Lee Mo Fan Memorial School. Temporary noise barrier observed to be transparent in nature was speculated to be ineffective; and it was observed that only 3 out of the 6 units of temporary noise barrier are installed. The complainant suggested that additional 6 sections of noise barrier shall be installed. The noise emanation was started from 0800hrs and he is a resident at 18 Wharf Road and his rest was adversely affected by the concerned noise emanation. He has contacted the Environmental Protection Department and the Police Force regarding the noise emanation. The Environmental Protection Department has replied that construction works conducted after 0700hrs does not violate statutory requirement while the Police Force has created an ICC complaint case file (2-4495970766) for follow up.

Based on review on relevant site record, noise impact associated with the breaking works on IECL opposite to the concerned location was observed across March 2018 and project related exceedances were recorded at nearby noise monitoring station at YLMF Memorial School across March 2018. Upon identification of the project related exceedance at YLMF memorial school noise monitoring station, the Contractor is requested to adopt remedial and enhancement measures to minimize the noise emanation and avoid noise impact to the nearby sensitive receivers.

According to ET follow up checking, the following enhancement measures were proposed and implemented by the Contractor by 16 March 2018 including provide additional temporary noise barrier and repair damaged or incomplete temporary noise barrier installed for the breaking works, provide additional acoustics screen to the breaking tip in addition to temporary noise barrier installed, provide covering of breaker tip with acoustic material for noise reduction and conduct breaking works intermittently

Nevertheless, subsequent to 16 March 2018, it was observed at times that the above mitigation measures were not fully implemented by the Contractor throughout the remaining breaking works period. Upon identification of deficiency in mitigation measures, the Contractor has been requested to rectify any deficiency observed and ensure relevant noise mitigation measures are implemented and the observed deficiencies are rectified prior to resumption of the concerned impact associated works. According to Contractor information, the concerned breaking works have been completed by 26 March 2018.
