Employment of Environmental Monitoring and Audit (EM&A) Personnel

2.1 An Environmental Team (ET) shall be established no later than one month before the commencement of construction of the Project. The ET shall be headed by an ET Leader. The ET Leader shall be a person who has at least 7 years' experience in EM&A or environmental management. The ET and the ET Leader shall be responsible for the implementation of the EM&A programme in accordance with the EM&A requirements as contained in the EM&A Manual. The ET Leader shall keep a contemporaneous log-book of each and every instance or circumstance or change of circumstances which may affect the findings of the EIA Report and each and every non-compliance with the recommendations of the EIA Report or this Permit. This log-book shall be kept readily available for inspection by all persons assisting in supervision of the implementation of the recommendations of the EIA Report and this Permit or by the Director or his authorized officers. Failure to maintain records in the log-book, failure to discharge the duties of the ET Leader as defined in the EM&A Manual or failure to comply with this Condition would entitle the Director to require the Permit Holder by notice in writing to replace the ET Leader. Failure by the Permit Holder to replace the ET Leader, or further failure to keep contemporaneous records in the log-book despite the employment of a new ET Leader may render the Permit liable to suspension, cancellation or variation. The ET shall not be in any way an associated body of the Contractor or the IEC for the Project.

2.2 The Permit Holder shall employ an Independent Environmental Checker (IEC) no later than one month before the commencement of construction of the Project. The IEC shall be a person who has at least 7 years' experience in EM&A or environmental management. The IEC shall be responsible for duties defined in the EM&A Manual, and shall audit the overall EM&A programme, including the implementation of all environmental mitigation measures, submissions required in the EM&A Manual, and any other submissions required under this Permit. In addition, the IEC shall be responsible for verifying the environmental acceptability of permanent and temporary works, relevant design plans and submissions under this Permit. The IEC shall verify the contemporaneous records of the log-book(s) mentioned in Condition 2.1 of this Permit. The IEC shall notify the Director by fax transmission, within 24 hours of receipt of notification from the ET Leader of each and every occurrence, change of circumstances or non-compliance with the recommendations of the EIA Report or this Permit, which might affect the monitoring or control of adverse environmental impacts. Where the IEC fails to so notify the Director of the same, fails to discharge the duties of the IEC as defined in the EM&A Manual or fails to comply with this Condition, the Director may require the Permit Holder by notice in writing to replace the IEC. Failure by the Permit Holder to replace the IEC as directed or further failure to so notify the Director despite employment of a new IEC may render the Permit liable to suspension, cancellation or variation. Notification by the Permit Holder is the same as notification by the IEC for the purpose of this Condition. The IEC shall not be in any way an associated body of the Contractor or the ET for the Project.

3. Submission and Measures During Construction of the Project

Management Organization of Main Construction Companies

3.1 The Permit Holder shall, within two weeks after the commencement of construction of the Project, inform the Director in writing the management organization of the main construction companies and/or any form of joint ventures associated with the construction of the Project, including the portion of the pipelines outside the Hong Kong Special Administrative Region (SAR) boundary. The submitted information shall include at least an organization chart, names of responsible persons and their contact details.

Construction Methods

3.2 The Project shall be constructed by using the appropriate installation techniques for the various sections of the pipelines alignment as described in the EIA Report and this Permit, and as indicated in Figures 1 and 2 of this Permit.

3.2a Jetting works for the pipeline between Location E and Location G shown in Figure 1 of this Permit shall be carried out by completing three jetting passes for each 2 kilometre section before moving onto the next 2 kilometre section along the alignment of the pipeline. The jetting machine shall complete the entire 2 kilometre section in one single pass before returning to the start of the section to begin the next pass, and the next pass shall not commence within 2 hours after the preceding pass has been completed. Jetting works for the next 2 kilometre section shall not commence within 12 hours after completion of the preceding section.

3.2b Jetting works for the pipeline between Location A and Location D shown in Figure 1 of this Permit shall be carried out by completing three jetting passes. Each jetting pass shall be continued and completed for the entire section before retuning to the start of the section to begin the next pass.

3.2c For a section of the pipeline of about 200 metres long between Location H and Location J shown in Figure 1 of this Permit where jetting can only be proceeded to about 1.1 metres to 1.3 metres below seabed level due to the presence of oyster shell deposits in the area, backfilling of armour rock will be replaced by grout mattresses for protection of the submarine pipeline. The method statement for installation of the grout mattresses described in Appendix F of this Permit shall be followed.

Pilot Test on Jetting Performance

3.3 A pilot test on the jetting technique as described in Appendix A of this Permit shall be fully and properly carried out for the purpose of verifying the water quality modelling predictions in the supporting assessment submitted with the application for variation of an Environmental Permit (Application No. VEP-191/2005) and the EIA Report. The results of the pilot test shall provide the basis to determine any remedial actions during the subsequent jetting operation. If the results indicate that the modelling predictions are being exceeded, remedial action, such as reduction in jetting speed, shall be taken immediately after the pilot test to ensure that exceedance of the Action and Limit levels for impact monitoring as defined in the EM&A Manual will not occur. The remedial action, including any reduction in jetting speed, shall be certified by the ET Leader and verified by the IEC as conforming to the predicted environmental performance in the EIA Report.

Pilot Test on Grouting Performance

3.3a A pilot test shall be carried out in accordance with the testing method as described in Appendix C of this Permit for the purpose of verifying the environmental performance of the grouting operation during installation of the grout mattress. If the grouting operation causes more than three or more consecutive exceedances in the water quality parameters being monitored during the pilot test, modifications to the subsequent operation shall be made and remedial actions shall be taken before continuing the remaining grout mattress installation works. The modifications and remedial actions shall be certified by the ET Leader and verified by the IEC as conforming to the environmental performance assessment submitted with the application for variation of an Environmental Permit (Application No. VEP 211/2006).

Mitigation Measures

3.4 To mitigate water quality impact arising from the construction works of the Project, the forward speed of the jetting machine for the construction of pipelines section between Location A to Location C, as shown in Figure 1 of this Permit, shall not exceed 67.5 metres per hour and 1.08 kilometres per day; and that for the construction of pipelines section between Location C to Location G shall not exceed 67.5 metres per hour and 1.62 kilometres per day.

3.5 Silt curtain shall be installed as indicated in Figure 3 of this Permit and properly maintained when works are being carried out at the Tai Po landing point site and the shore approach section, and when jetting works are being carried out within 2 kilometres from the proposed landing point at the seawall of the Tai Po Industrial Estate, except during the pilot test on jetting performance as required in Condition 3.3 above. Any proposal to modify the length of silt curtain shall be supported by EM&A results and submitted for the agreement by the Director before implementation. The environmental acceptability of such modification shall also be certified by the ET Leader and verified by the IEC before submission to the Director.

3.6 Grab dredger shall be used for the dredging works between Location D to Location E as shown in Figure 1 of this Permit, and no more than three grab dredgers operating with a separation distance of no less than 1,000 m between each other shall be allowed to dredge at any one time along the pipelines route.

3.7 The dredging rate for each grab dredger during dredging between Location D to Location E, as shown in Figure 1 of this Permit, shall not exceed 250 cubic metres per hour and 6,000 cubic metres per day.

3.8 To avoid localised aesthetic impacts at the sea surface due to escape of marine mud from the ascending grab to the upper layer of the water column, frame type silt curtain with details shown in Figure 4 and Figure 5 of this Permit shall be employed at each grab dredger for dredging between Location D to Location E as shown in Figure 1 of this Permit. The silt curtains shall be properly maintained throughout the dredging operation.

3.9 All barges used for the transport of dredged materials shall be fitted with tight bottom seals and filled to an appropriate level to ensure that dredged materials do not spill over during transport to the disposal site, and adequate free board shall be maintained to ensure that the decks are not washed by wave action.

3.10 Dredging works and jetting works of the Project shall not be carried out simultaneously.

3.11 The Measures for Pollution Prevention and Control in Appendix E of this Permit shall be fully and properly implemented during the grout mattress installation works. Amongst other measures, an appropriate number of experienced and properly equipped divers shall be deployed to observe and monitor the underwater works for any abnormalities throughout the whole grouting process. Effective communication between the divers and the operators on board the construction vessel shall be maintained. The maximum grout pumping rate shall not be greater than 1cubic metre per ten minutes (1 cu.m/10 min). Should there be any signs of leakage or spillage, the grouting operation shall be stopped immediately. Appropriate remedial actions and/or mitigation in Appendix E of this Permit shall be implemented.

4. Environmental Monitoring and Audit (EM&A) Requirements During Construction Period

4.1 Subject to amendments as stated in Appendix B of this Permit, the EM&A programme for the construction of the Project shall be implemented in accordance with the procedures and requirements set out in the EM&A Manual. The EM&A programme for the grout mattress installation works of the Project shall also be implemented in accordance with the procedures and requirements set out in Appendix D of this Permit. Any changes to the EM&A programme shall be justified by the ET Leader and verified by the IEC as conforming to the requirements set out in the EM&A Manual, and shall be submitted to the Director for approval.

4.2 Samples, measurements and necessary remedial actions shall be taken in accordance with the requirements of the EM&A Manual and Appendix D of this Permit by:

(a) conducting baseline environmental monitoring on water quality and marine ecology;

(b) conducting impact monitoring on water quality and marine ecology;

Appendix A

Pilot Test on Jetting Performance

In order to verify the modelling predictions in the EIA Report and the supporting assessment submitted with the application for variation of an Environmental Permit (Application No. VEP-191/2005), a pilot test will be conducted during jetting works commencing from either the Tai Po landing point or the Hong Kong Special Administrative Region (HKSAR) waters boundary. If the jetting operation commences at the Tai Po landing point, the pilot test will be conducted in accordance with Section 3.2.5 of the EM&A Manual. If the jetting operation commences at the HKSAR boundary, the procedure and requirements for the pilot test as set out in the following paragraphs below shall supersede the corresponding parts in Section 3.2.5 of the EM&A Manual.

Commencement of Jetting at the HKSAR Boundary

The pilot test will consist of intensive water quality monitoring of all three jetting passes along the first 2-km section. The sea area to be monitored will cover 400 metres perpendicular to the first 2-km section on both sides of the pipeline alignment.

Stations

A set of monitoring stations will be arranged perpendicularly to the jetting alignment. Monitoring locations will be fixed throughout the whole monitoring. The locations of the stations are illustrated in Figure A1.

Monitoring Programme

The jetting works in Mirs Bay between Location E and Location G, shown in Figure 1 of this Permit will be carried out 24 hours per day and the expected jetting programme is outlined in Table A1 below:

Table A1 Jetting Programme in Mirs Bay

Day Number	Time^**	Activity
Day 1	00:00 - 24:00	First 1.62km of Pass 1
Day 2	00:00 – 05:40	Remaining 0.38km of Pass 1
	05:40 - 07:40	Dredger relocates to the start of the 2km section
	07:40 - 24:00	First 1.1km of Pass 2
Day 3	00:00 - 13:20	Final 0.9km of Pass 2
	13:20 - 15:20	Dredger relocates to the start of the 2km section
	15:20 - 24:00	First 585m of Pass 3
Day 4	00:00 - 21:00	Final 1.4km of Pass 3

Note: ** Works will proceed continuously for 24 hours each day. The start time on Day 1 is assumed to be 00:00 for the purposes of presentation of the programme. The actual start time should be confirmed by the contractor.

The water quality impact of all three jetting passes will be monitored. For each jetting pass, the monitoring line will be located 100m from the start of the 2 km section. Monitoring will begin when the pass commences and continue until the completion of the pass. The monitoring will be repeated when the next pass begins after relocation of the jetting machine.

Frequency

The same requirements as set out in Section 3.2.5 of the EM&A Manual shall apply.

Reporting

The same requirements as set out in Section 3.2.5 of the EM&A Manual shall apply.

Actions

The results of the pilot test will indicate how the jetting works are performing in comparison with the modelling predictions presented in the supporting assessment submitted with the application for variation of an Environmental Permit (Application No. VEP-191/2005). If the results indicate that the modelling predictions are being exceeded, the Contractor will take remedial actions, such as reduction in jetting speed, to ensure that exceedances of the appropriate Action and Limit levels for the Impact Monitoring will not occur during subsequent jetting works. For the purpose of checking whether the jetting machine is performing according to the modelling predictions, the following protocols should be adopted to analyse the monitoring results.

The monitoring results refer to the pilot test stations as presented in Figure A1.

Step 1 Analyse the results of monitoring for the three jetting passes of the 2 km section to determine the range of SS values recorded at the monitoring stations. The data analysis should focus on bed layer results at the stations located 400m from the jetting alignment as these are most relevant to the impact assessment on the key sensitive coral sites.

Step 2 The recorded values should then be compared against the coral tolerance criterion of an elevation of 10 mg L^-1 above ambient.

Step 3 If the SS elevations are less than the coral tolerance criterion then no further actions are required as a result of the pilot test. If the SS elevations are greater over three consecutive monitoring events on any one jetting pass then the percentage deviations should be determined. For example if the pilot test indicates that the 400m stations record three consecutive elevations of 12 mg L^-1 then the performance of the jetting machine can be seen to differ consistently by + 20 % from the predictions in the supporting assessment submitted with the application for variation of an Environmental Permit (Application No. VEP-191/2005). The data from the other monitoring stations should be examined to determine whether the jetting machine is the cause of the exceedance. If the 400m stations record higher values than the stations closer to the jetting machine then it may indicate that other factors have caused the exceedances.

Step 4 Based on the findings of Step 3 the Contractor in conjunction with the ET Leader and IEC should decide on appropriate reductions to the jetting rate. Remedial actions associated with exceedances of Action and Limit levels are discussed in Section 3.3 of the EM&A Manual.
