EXECUTIVE SUMMARY

NTT Com Asia (NTTCA) proposes to install a telecommunication cable (Asia Submarine-cable Express (ASE) cable) of approximately 7,200 km in length, connecting Japan and Singapore with branches to the Philippines, Hong Kong SAR (HKSAR) and Malaysia.  A Project Profile (PP-452/2011) which includes an assessment of the potential environmental impacts associated with the installation of the submarine telecommunications cable system was prepared and submitted to the Environmental Protection Department (EPD) under section 5.(1)(b) and 5.(11) of the Environmental Impact Assessment Ordinance (EIAO) for the application for Permission to apply directly for Environmental Permit (EP).  The Environmental Protection Department, subsequently issued an Environmental Permit (EP- 433/2011). 

This is the Ninth Weekly Site Inspection Report that presents the findings of the site inspection and other EM&A activities undertaken during the period from 26 November 2012 to 2 December 2012.  

Environmental Site Inspection

A weekly joint environmental site inspection was carried out by the representatives of the Contractor and the Environmental Team (ET).  Environmental performance complied with the environmental requirements and all necessary mitigation measures were properly implemented.

Marine Mammal Observation (MMO)

Daily marine mammal exclusion zone monitoring was not carried out in the reporting period as the cable installation works in Zone C and from C to the boundary of HKSAR waters were completed on 24 October 2012.

Environmental Complaints, Non-compliance & Summons

No non-compliance with PP recommendations, EP conditions and other requirements associated with the construction of the Project was recorded in the reporting period.

No environmental complaint was received in this reporting period.

No environmental summons was received in this reporting period.

Upcoming Works for the Next Reporting Period

Works to be undertaken in the coming reporting period would include beach manhole construction and land duct laying works.  Potential environmental impacts arising from these construction activities are mainly associated with dust, construction noise and waste management.

For the submarine cable installation part, cable laying works will continue to be conducted in China waters, which are out of the scope of the current EM&A.

2.1                                          Background

NTT Com Asia (NTTCA) proposes to install a telecommunication cable (Asia Submarine-cable Express (ASE) cable) of approximately 7,200 km in length, connecting Japan and Singapore with branches to the Philippines, Hong Kong SAR (HKSAR) and Malaysia.  NTTCA is responsible for securing the approval to land the ASE cable in Tseung Kwan O, Hong Kong SAR (HKSAR).  The proposed landing site will be at a new Beach Manhole (BMH) and ultimately connect with a Data Centre in Tseung Kwan O (TKO) Industrial Estate which is scheduled for completion in 2012.  From Tseung Kwan O, the cable will extend eastward approaching the Tathong Channel.  Near to Cape Collinson, the cable is approximately parallel to the Tathong Channel until north of Waglan Island where the cable travels eastward to the boundary of HKSAR waters where it enters the South China Sea.  The total length of cable in Hong Kong SAR waters is approximately 33.5 km.  A map of the proposed cable route is presented in Annex A.

A Project Profile (PP-452/2011) which includes an assessment of the potential environmental impacts associated with the installation of the submarine telecommunications cable system was prepared and submitted to the Environmental Protection Department (EPD) under section 5.(1)(b) and 5.(11) of the Environmental Impact Assessment Ordinance (EIAO) for the application for Permission to apply directly for Environmental Permit (EP).  The Environmental Protection Department, subsequently issued an Environmental Permit (EP- 433/2011). 

Under the requirements of Condition 2.4 of the EP, an EM&A programme as set out in the revised Environmental Monitoring and Audit Manual (EM&A Manual) is required to be implemented.  The EM&A programme includes water quality monitoring, marine mammal observation, coral monitoring and weekly site inspection. 

2.2                                          Works Programme and Works Locations

The location of the cable installation works within the boundary of Hong Kong SAR waters is shown in Annex A, while the location of the landing point (ie new Beach Manhole (BMH) in TKO Industrial Estate) is shown in Annex B.  The preliminary construction programme of the Project is given in Figure 2.1.

3                                                Environmental Monitoring

3.1                                          Cable Installation Water Quality Monitoring

Baseline water quality monitoring was completed by the end of September 2012.  Baseline Water Quality Monitoring Reports for Zone A, Zone B and Zone C were submitted on 19 September 2012, 25 September 2012 and 1 October 2012, respectively.

Daily impact water quality monitoring was not conducted in the reporting period as no cable laying works in Zone A, Zone B and Zone C were involved from 26 November 2012 to 2 December 2012.

3.2                                          Marine Mammal Observation (MMO)

Daily marine mammal exclusion zone monitoring is required to be conducted during the cable installation works taking place in daylight hours along the sections outside Zone A to Zone B (ie Zone C and from C to the boundary of HKSAR waters).  This monitoring was not carried out in the reporting period as the cable installation works in Zone C and from C to the boundary of HKSAR waters were completed on 24 October 2012.

3.3                                          Coral Monitoring

Baseline coral monitoring was completed in September 2012.  The Baseline Coral Monitoring Survey Report was submitted on 28 September 2012.  Post-project coral monitoring will be conducted within one month after completion of the jetting works, with the Post-project Coral Monitoring Survey Report to be submitted within one month after completion of the marine works.  Impact monitoring for coral during cable installation works is not required under the Project. 

In the week of 8 October 2012 when the cable installation barge passed the identified coral communities as presented in the Baseline Coral Monitoring Survey Report, the nearest distances between the barge and the identified coral communities in Zone A and Zone B were 230m and 270m respectively, indicating the cable alignment of more than 180m away from the identified coral communities as required in the Environmental Permit (EP- 433/2011). 

3.4                                          Site Inspection and Audit

In accordance with the revised EM&A Manual, a weekly site inspection should be undertaken at the landing point (ie new Beach Manhole (BMH) in TKO Industrial Estate) to ensure that the appropriate environmental protection and pollution control mitigation measures are properly implemented in accordance with the Project Profile (PP-452/2011).  Results of the site inspection in the reporting period are provided in Section 4.

4                                                Site Inspection Results

The weekly site inspection is required to be carried out by the representatives of the Contractor and the Environmental Team (ET).  A Site Inspection Log is completed by the ET representative to record whether the Contractor is compliant with environmental regulations in terms of noise, water quality and housekeeping etc (Annex C).

During the reporting period, the site inspection was conducted on 29 November 2012 by the representatives of the Contractor and the ET.  Construction works of the cable landing point were observed ongoing in the rain.  There was no non-compliance recorded during the site audit.  Major findings and recommendations are summarised as follows:    

(i)         A copy of EP was displayed conspicuously at the vehicular site entrance in accordance with the requirement of Condition 1.5 of the EP.

(ii)        Middle section of the land duct was completed.  For the completed part, excavated materials have been backfilled into the trench and the site has been reinstated to its original status (Annex D Photo No. 1).

(iii)       Impermeable sheets were observed to have been placed in some portions of the stockpiles of excavated soils and rocks, but large portion of stockpiles were still exposed under the rain (Annex D Photo No. 2).  The Contractor was reminded to cover all stockpiles completely during rain events to prevent storm runoff, which would transport the sediment and eventually deposit it in nearby sea water, storm drains or low-lying areas. 

 

5                                                Environmental Non-Conformance

5.1                                          Summary of Environmental Non-compliance
