2.            NOISE

 

2.1.      Monitoring Requirements

To ensure no adverse noise impact, noise monitoring is recommended to be carried out within 300m radius from the nearby noise sensitive receivers (NSRs), during construction phase. The NSRs selected as monitoring station are (i) NSR4 - Creative Secondary School, (ii) NSR24 - PLK Laws Foundation College, and (iii) NSR31 - School of Continuing and Professional Studies - CUHK respectively.

 

2.2.      Monitoring Locations

 

The monitoring locations were normally made at a point 1m from the exterior of the NSRs building façade and be at a position 1.2m above the ground. A correction of +3dB(A) was made to the free- field measurements.

According to the environmental findings detailed in the EIA report and Baseline Monitoring Report, the designated locations for the construction noise monitoring are listed in Table 2.1 below.

2.3.      Monitoring Parameter, frequency and duration

 

Construction noise level were measured in terms of the A-weighted equivalent continuous sound pressure level (LAeq). Leq 30min was used as the monitoring parameter for the time period between 0700 and 1900 on normal weekdays. Table 2.2 summarizes the monitoring parameters, frequency and duration of the impact noise monitoring.

Notes: Limits specified in the GW-TM and IND-TM for construction and operation noise, respectively.

 

If exceedances were found during noise monitoring, the actions in accordance with the Event and Action Plan shall be carried out according to Appendix E.


 

 

2.6.                Monitoring Results and Observations

 

Referring to EM&A manual Section 4.1.2, the impact noise monitoring should be carried out when there are Contract-related construction activities undertaken within a radius of 300m from the monitoring stations. No monitoring station was located within a radius of 300m of the Contract site as shown in Figure 2.4, no impact monitoring for noise impact was conducted in the reporting period.

3.            WATER QUALITY

 

In accordance with the recommendations of the EIA, water quality EM&A is required during dredging for the submarine pipelines and, during operation phase. In addition, baseline water quality monitoring was prior to the commencement of marine construction activities.

The following Section provides details of the water quality monitoring to be undertaken by the Environmental Team (ET) to verify the distance of sediment and brine plume dispersion and to identify whether the potential exists for any indirect impacts to occur to ecological sensitive receivers.

Water quality monitoring for the Contract can be divided into the following stages:

 

-               Dredging activities during construction phase;

 

-               Discharge of effluent from main disinfection during construction phase;

 

-               Operation phase - first year upon commissioning; and,

 

-               Continuous monitoring of effluent quality.

 

In addition, the marine works contractor is required to complete a silt curtain efficiency test for the combined use of floating silt curtain type and cage type silt curtain for dredging at seawater intake to confirm the silt curtain reduction efficiency assumptions of the assessment. The details of testing plan together with the silt curtain deployment plan shall be submitted by the ET to seek approval from the IEC and EPD.

 

3.1.       Water Quality Parameters

 

The parameters that have been selected for measurement in situ and in the laboratory are those that were either determined in the EIA to be those with the most potential to be affected by the construction works or are a standard check on water quality conditions. Parameters to be measured in the impact water quality monitoring are listed in Table 3.1.

3.5.       Monitoring Programme

 

No marine water quality monitoring was conducted between March 2020 to February 2021. Marine construction works and dredging activities for the Project were commencement in March 2021 and April 2021 respectively.

The ET of the Contract had conducted the impact water quality monitoring between 1 March 2021 to 31 March 2021 at the ten designated monitoring stations and the six designated monitoring at waters near TKO in accordance with the EM&A Manual and Contract Specification respectively.


3.6.       Monitoring results and observations

 

The impact water quality monitoring at the designated locations were conducted by the ET as scheduled in the reporting period. The graphical presentation of the water quality monitoring result was shown in Appendix D.

Six (6) of the general water quality monitoring results of SS obtained had exceeded the Action level. One (1) of the general water quality monitoring results of SS obtained during the reporting period had exceeded the Limit Level.

Details of the exceedance could be referring to Appendix O of the Monthly EM&A Report.

 

 

 


4.            WASTE

 

The waste generated from this Project includes inert construction and demolition (C&D) materials, and non-inert C&D materials. Non-inert C&D materials are made up of general refuse, vegetative wastes and recyclable wastes such as plastics and paper/cardboard packaging waste. Steel materials generated from the project are also grouped into non-inert C&D materials as the materials were not disposed of with other inert C&D materials. Details of cumulative waste management data are presented as a waste flow table in Appendix F.

 

 

 


5.            LANDFILL GAS MONITORING

 

5.1.       Monitoring Requirement

In according with Section 11 of the EM&A Manual, monitoring of landfill gas is required for construction works within the 250m Consultation Zone. Part of the desalination plant and the indicative area of natural slope mitigation works fall within the SENT Landfill Extension Consultation Zone; and part of the 1,200 mm diameter fresh water mains along Wan Po Road falls within the SENT Landfill and SENT Landfill Extension Consultation Zones, TKO Stage II/III Restored Landfill and TKO Stage I Restored Landfill Consultation Zones.

For the part of the desalination plant and the indicative area of natural slope mitigation works fall within the SENT Landfill Extension Consultation Zone in this contract, since the SENT Landfill Extension is still under construction, the Landfill gas monitoring will be conducted after the commencement of operation of the SENT Landfill Extension which will be 2021 Quarter 3 according to the latest construction programme shown in the monthly EM&A Report of SENT Landfill Extension. The Contractor¡¦s safety officer will keep review the necessity of landfill gas monitoring during the construction stage. No landfill gas monitoring was conducted in the reporting period.

No noise monitoring was conducted in the reporting period due to the over distant monitoring station from the works location, in which construction activities were not undertaken within a radius of 300m from the monitoring locations.

 

The EM&A works for water quality were conducted during the reporting period in accordance with the EM&A Manual.

Six (6) of the general water quality monitoring results of SS obtained had exceeded the Action level. One (1) of the general water quality monitoring results of SS obtained during the reporting period had exceeded the Limit Level. All Action and Limit Level exceedances were unrelated to the project.

 

Details of the exceedance could be referring to Appendix O of the represent Monthly EM&A Report.

 

No landfill gas monitoring was conducted in the reporting period.

 

Weekly environmental site inspection was conducted during the reporting period. Minor deficiency was observed during site inspection. The environmental performance of the project was therefore considered satisfactory.

 

According to the environmental site inspections performed in the reporting month, the Contractor is reminded to pay attention on maintaining proper materials storage, site tidiness and dust suppression mitigation measures.

 

No environmental complaint was received in the reporting period.

 

No notification of summons or prosecution was received since commencement of the Contract.

 

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