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 First Weekly Site Inspection Report that presents the findings of the site inspection and other EM&A activities undertaken during the period from 4 to 7 October 2012.  

Environmental Site Inspection

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

Marine Mammal Observation

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 has not started.

Summary of Breaches of Action/Limit Levels

Per plan, no marine water quality monitoring was conducted in the reporting period.  Thus, no exceedances of Action and Limit Levels for water quality were recorded during the reporting week.

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 this 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 monitoring period include cable laying works in Zone A, seawall duct work, land duct laying works and beach manhole construction. 

Potential environmental impacts arising from the above construction activities are mainly associated with marine water quality, dust, construction noise and waste management.

2                                            Project Information

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.  It should be noted that Tseung Kwan O is currently the landing site for a number of submarine cables.  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.

No impact water quality monitoring was conducted during the reporting period as the cable laying works has yet to commence.  Mitigation measures to control water quality pollution as recommended in the PP will be checked in due course and summarised in the Weekly Water Quality Impact Monitoring Reports.

3.2                                      Marine Mammal Observation

Daily marine mammal exclusion zone monitoring is required to be conducted during the cable installation works taking place in daylight hours along the section 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 has not started. 

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. 

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 such as noise, water quality and housekeeping etc (Annex C).

During the reporting period, the site inspection was conducted on 5 October 2012 by the representatives of the Contractor, the ET and NTTCA.  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. (Annex D Photo No. 1)

(ii)        A silt curtain was employed around the seawall area in order to reduce the dispersion of sediments from the landing site (Annex D Photo No. 2).

(iii)       Spillage containment such as dip tray was found to have been provided for the equipment (eg generator), which potentially has oil leakage (Annex D Photo No. 3).

(iv)      Housekeeping of the construction site was observed to have been conducted in a proper way.  A portable toilet has been placed on site (Annex D Photo No. 4), and general refuse was not frequently found.  The Contractor was nevertheless recommended to provide enough rubbish bins within the construction site for better rubbish disposal.  Following-up actions by the Contractor will be checked in next week’s site inspection.

(v)       An idling excavator was observed during the site inspection.  The Contractor was reminded to turn off all equipment/ vehicles when they are not actively in use.  The excavator was turned off by the Contractor immediately after the recommendation.

(vi)      The Contractor was suggested to display labels stating the sound power level in dB on all major PME.  The corrective action was being undertaken as observed during the same audit and will be checked in next week’s site inspection.

5                                              Environmental Non-Conformance

5.1                                      Summary of Environmental Non-compliance

No non-compliance event was recorded during the reporting period.  Since construction phase impact water quality monitoring has not commenced, no non-compliance of Action and Limit Levels for water quality was recorded during the reporting week.

5.2                                      Summary of Environmental Complaint

No complaint was received during the reporting period. 

5.3                                      Summary of Environmental Summon and successful prosecution

7                                              Conclusions

This First Weekly Site Inspection Report presents the findings of the site inspection and other EM&A activities undertaken during the period from 4 to 7 October 2012, in accordance with the PP (Register No. PP – 452/2011), revised EM&A Manual and the requirements of Environmental Permit (EP- 433/2011). 

Since there were no jetting activities during the reporting period, no construction phase impact water quality and marine mammal monitoring were deemed necessary and hence none was conducted during the reporting period.  No exceedance of Action and Limit Levels of water quality was reported during the reporting period.

A weekly joint environmental site inspection was conducted in the reporting period.  It confirmed that the environmental mitigation measures recommended in the PP were properly implemented by the Contractor.

No non-compliance event was recorded during the reporting period.

No complaint and summons/prosecution was received during the reporting period.

The ET will keep track on the construction works to confirm compliance of environmental requirements and the proper implementation of all necessary mitigation measures.
