2.             NOISE

MONITORING REQUIREMENTS

2.1.        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.        In accordance with the EM&A Manual, baseline noise level at the noise monitoring stations were established as presented in the Baseline Monitoring Report. Impact noise monitoring will be conducted once per week in the form of 30-minutes measurements Leq, L10 and L90 levels recorded at each monitoring station between 0700 and 1900 on normal weekdays.

 

2.3.        Referring to EM&A manual Section 4.1.2, the impact noise monitoring should be carried out at all the designated monitoring stations when there are contract-related construction activities undertaken within a radius of 300m from the monitoring stations.

 

2.4.        No impact monitoring for noise impact was conducted in the reporting month due to the overly distant monitoring station from the works location, where they were farther than 1 km from the closest monitoring station NSR4 to the works location.

 

2.5.        Impact noise monitoring will be conducted weekly in the reporting period between 0700- 1900 on normal weekdays. Construction works would follow stipulations of the valid Construction Noise Permits if works had to be conducted during restricted hours or public holidays.

 

2.6.        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.

IMPACT MONITORING METHODOLOGY

2.10.    Integrated sound level meter was used for the noise monitoring. The meter was in compliance with the International Electrotechnical Commission Publications 651: 1979 (Type 1) and 804: 1985 (Type 1) specifications. Immediately prior to and following each noise measurement the accuracy of the sound level meter was checked using an acoustic calibrator generating a known sound pressure level at a known frequency. Measurements was accepted as valid only if the calibration levels before and after the noise measurements agree to within 1.0 dB(A). Calibration certificates of the instruments used to be shown at Appendix F are intentionally left blank since no impact monitoring equipment was used in the reporting month.

 

2.11.    Noise measurements were not made in the presence of fog, rain, wind with a steady speed exceeding 5 m/s or wind with gusts exceeding 10 m/s. The wind speed shall be checked with a portable wind speed meter capable of measuring the wind speed in m/s.

 

ACTION AND LIMIT LEVELS

2.12.    The Action/Limit Levels are in line with the criteria of Practice Note for Professional Persons (ProPECC PN 2/93) ¡§Noise from Construction Activities - Non-statutory Controls¡¨ and Technical Memorandum on Environmental Impact Assessment Process issued by HKSAR Environmental Protection Department [¡§EPD¡¨] under the Environmental Impact Assessment Ordinance, Cap 499, S.16 are presented in Table 2.3.

3.           WATER QUALITY

3.1.        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 will be required 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. The water quality monitoring programme will be carried out to allow any deteriorating water quality to be readily detected and timely action taken to rectify the situation. The status and locations of water quality sensitive receivers and the marine works location may change after issuing this Document. If required, the ET in consultation with IEC will propose updated monitoring locations and seek approval from EPD.

3.2.        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.

 

3.3.        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.

3.4.        With the onset of marine dredging activities in late April 2021 at Outfall Shaft Area, a silt curtain efficiency test has been conducted at the Outfall Shaft Area on 16th April 2021 at 6 monitoring intervals (08:00, 10:00, 12:00, 14:00, 16:00, 18:00). The baseline monitoring event has been conducted on 10th April 2021 at 5 monitoring locations. Testing protocols and methodologies had followed the guidelines as presented in the EM&A Manual Annex C. Detailed analysis of in-situ and laboratory data was presented in a separate report which has been submitted to EPD after approval by IEC on 31 May 2021. The overall Silt Removal Effectiveness at Outfall Shaft Area for the combined used of cage and floating type silt curtains was 95.28%.

WATER QUALITY PARAMETERS

3.5.        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 baseline monitoring are listed in Table 3.1.

3.6.        In addition to the water quality parameters, other relevant data were also be measured and recorded in Water Quality Monitoring Logs, including the location of the sampling stations, water depth, time, weather conditions, sea conditions, tidal stage, current direction and velocity, special phenomena and work activities undertaken around the monitoring and works area that may influence the monitoring results.

MONITORING EQUIPMENT

3.7.        For water quality monitoring, the following equipment will be used:

 

Dissolved Oxygen and Temperature Measuring Equipment - The instrument was a portable, weatherproof dissolved oxygen measuring instrument complete with cable, sensor, comprehensive operation manuals, and was operable from a DC power source. It was capable of measuring: dissolved oxygen levels in the range of 0 - 20 mg/L and 0 - 200% saturation; and a temperature of 0 - 45 degrees Celsius. It has a membrane electrode with automatic temperature compensation complete with a cable of not less than 35 m in length. Sufficient stocks of spare electrodes and cables were available for replacement where necessary (e.g. YSI model 59 DO meter, YSI 5739 probe, YSI 5795A submersible stirrer with reel and cable or an approved similar instrument).

 


Turbidity Measurement Equipment - The instrument was a portable, weatherproof turbidity-measuring unit complete with cable, sensor and comprehensive operation manuals. The equipment was operated from a DC power source, it has a photoelectric sensor capable of measuring turbidity between 0 - 1000 NTU and complete with a cable with at least 35 m in length (for example Hach 2100P or an approved similar instrument).

Salinity Measurement Instrument - A portable salinometer capable of measuring salinity in the range of 0 - 40 ppt was provided for measuring salinity of the water at each monitoring location.

Water Depth Gauge - A portable, battery-operated echo sounder (for example Seafarer 700 or a similar approved instrument) was used for the determination of water depth at each designated monitoring station. This unit will preferably be affixed to the bottom of the work boat if the same vessel is to be used throughout the monitoring programme. The echo sounder was suitably calibrated.

Positioning Device - A Global Positioning System (GPS) was used during monitoring to allow accurate recording of the position of the monitoring vessel before taking measurements. The Differential GPS, or equivalent instrument, was suitably calibrated at appropriate checkpoint (e.g. Quarry Bay Survey Nail) to verify that the monitoring station is at the correct position before the water quality monitoring commence.

Water Sampling Equipment - A water sampler, consisting of a PVC or glass cylinder of not less than two litres, which can be effectively sealed with cups at both ends, was used (e.g. Kahlsico Water Sampler 13SWB203 or an approved similar instrument). The water sampler has a positive latching system to keep it open and prevent premature closure until released by a messenger when the sampler is at the selected water depth.

Total Residual Chlorine for Discharge of Sterilization Water - Total residual chlorine (TRC) shall be measured in-situ using a handheld colorimeter with its testing toolkits.

SAMPLING / TESTING PROTOCOLS

3.8.        All in situ monitoring instruments were checked, calibrated and certified by a laboratory accredited under HOKLAS or any other international accreditation scheme before use, and subsequently re-calibrated at monthly intervals throughout the stages of the water quality monitoring. Responses of sensors and electrodes were checked with certified standard solutions before each use.

3.9.        On-site calibration of field equipment was follow the ¡§Guide to On-Site Test Methods for the Analysis of Waters¡¨, BS 1427: 2009. Sufficient stocks of spare parts were maintained for replacements when necessary. Backup monitoring equipment was made available so that monitoring can proceed uninterrupted even when equipment is under maintenance, calibration etc.

 


LABORATORY MEASUREMENT AND ANALYSIS

3.10.    All laboratory works were carried out in a HOKLAS accredited laboratory. Sufficient volume of each water sample was collected at the monitoring stations for carrying out the laboratory analyses.

3.15.    During periods when there are dredging works, impact monitoring was undertaken at the monitoring stations as shown in Figure 3.1 and Table 3.3 three days per week during the construction phase after the commencement of marine construction works and dredging activities. Monitoring at each station was undertaken at both mid-ebb and mid-flood tides on the same day. The tidal range selected for the impact monitoring was at least 0.5 m for both flood and ebb tides as far as practicable. The interval between two sets of monitoring was not less than 36 hours. The monitoring frequency would be increased in the case of exceedances of Action/Limit Levels if considered necessary by ET. Monitoring frequency would be maintained as far as practicable.

3.16.    The monitoring location/position, time, water depth, water temperature, salinity, weather conditions, sea conditions, tidal stage, special phenomena and work underway at the marine works site were recorded.

SAMPLING DEPTHS & REPLICATION

3.17.    For Impact monitoring, each station was sampled and measurements/ water samples was taken at three depths, 1 m below the sea surface, mid-depth and 1 m above the seabed. For stations that are less than 3 m in depth, only the mid depth sample was taken. For stations that are less than 6 m in depth, only the surface and seabed sample were taken. For in situ measurements, duplicate readings were made at each water depth at each station. Duplicate water samples were collected at each water depth at each station. All observations and results were recorded in the data record sheets in Appendix L.

ACTION AND LIMIT LEVELS

3.18.    The Action and Limit Levels have been set based on the derivation criteria specified in the EM&A Manual, as shown in Table 3.4 below. Based on the baseline water quality monitoring data and the derivation criteria specified in Table 3.4, the Action/Limit Levels have been derived and are presented in Table 3.5.

MONITORING PROGRAMME

3.19.    The ET of the Contract had conducted the baseline water monitoring between 12 May 2020 to 6 Jun 2020 at the thirteen designated monitoring stations and the six designated monitoring at waters near TKO in accordance with the EM&A Manual and Contract Specification respectively. The monitoring results was presented in Baseline Water Quality Monitoring Report separately.

3.20.    The commencement of marine construction and dredging activities for the Contract have been conducted in March and April 2021 respectively.

MONITORING RESULTS AND OBSERVATIONS

3.21.    General water quality monitoring at the ten monitoring stations (CE, CF, WSR1, WSR2, WSR3, WSR4, WSR16, WSR33, WSR36 and WSR37) were conducted on 4, 8, 10, 12, 15, 17, 19, 22, 24 and 26 February 2022.

3.22.    Fifty-four (54) of the general water quality monitoring results of suspended solids (SS) obtained had exceeded the Action Level. Thirty-eight (38) of the general water quality monitoring results of SS obtained during the reporting period had exceeded the Limit Level. Details of the exceedance are presented in Appendix O.

3.23.    Investigation on the reason of exceedance has been carried out, where the exceedances of SS 4, 8, 10, 12, 15, 17, 19, 22, 24 and 26 February 2022 were concluded to be unrelated to the Contract as detailed in the Incident Reports on Action Level or Limit Level Non-compliance along with supporting materials in Appendix O.

3.24.    Monitoring results of 6 key parameters: Salinity, DO, turbidity, SS, pH and temperature in this reporting, are summarized in Table 3.6 and Table 3.7, and detailed results are presented in Appendix L.

5.1.        In accordance 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.

MONITORING LOCATION

5.2.        Monitoring of oxygen, methane, carbon dioxide and barometric pressure would be performed for excavations at 1m depth or more within the consultation Zone.

5.3.        During construction of works within the consultation zones, excavations of 1m depth or more was monitored:

 

-  At the ground surface before excavation commences;

-  Immediately before any worker enters the excavation;

-  At the beginning of each working day for the entire period the excavation remains open; and

-  Periodically through the working day whilst workers are in the excavation.

 

5.4.        For excavations between 300mm and 1m deep, measurements were carried out:

 

-  Directly after the excavation has been completed; and

-  Periodically whilst the excavation remains open.

 

MONITORING PROGRAMME

5.5.        Since part of the desalination plant (Wan Po Road and MIC compound/Basketball Court) and the indicative area of natural slope mitigation works fall within the SENT Landfill Extension Consultation Zone in this contract (Figure 5.1), landfill gas monitoring would be required for Wan Po Road and MIC compound/Basketball Court (Figure 5.2) if excavations were conducted at more than 300mm deep. Although SENT Landfill Extension has commenced operation since November 2021, no excavation works were conducted at MIC compound/Basketball Court. Hence no landfill gas monitoring would be scheduled for MIC compound/Basketball Court at the current stage. In this reporting period, 18 time of landfill gas monitoring was recorded at Wan Po Road (Ch1+625 - Ch1+513). No exceedance of action and limit levels for oxygen, methane and carbon dioxide was observed. Monitoring was conducted during excavations at 1m depth or more within the consultation zone and whenever workers entered the excavation on the day.

 


MONITORING LOCATION

5.6.        The area required to be monitored for landfill gas in the reporting period is shown in Figure 5.2.


 

Figure 5.1         Overview of the SENT Extension Consultation Zone and the Contract Site Area

S12.7

The manholes and utility pits within the Project Site and along the fresh water mains. Each manhole/ utility pit should be monitored with two measurements (at mid depth and base). Each measurement should be monitored for a minimum of 10 minutes. A steady reading and peak reading should be recorded at each manhole/ utility pit and for each measurement. The need for venting the manhole/ utility pit and further monitoring will be reviewed after the initial monitoring.

S12.7

All construction, operation and maintenance personnel working on-site as well as visitors should be made aware of the hazards of landfill gas and its possible presence on-site. This should be achieved through a combination of posting warning signs in prominent places and also by access to detailed

information on landfill gas hazards and the designs and procedural means by which these hazards are being minimized on-site.

Note:

* - Due to safety concern of vessel transportation earlier than 0700, Water Quality Monitoring would start at 0800.

$ - Since predicted tide is shorter than 3.5 hours, method of 90% tidal period as monitoring time is adopted.

& - Due to safety concern for sampling event in night-time, method of 90% tidal period as monitoring time is approached and end at 1900.

# - Prioritized routing: Mid-Ebb: CE¡÷WSR16¡÷WSR37¡÷WSR36¡÷WSR33¡÷Remaining stations and Mid-Flood: CF¡÷WSR1¡÷WSR2¡÷WSR3¡÷WSR4¡÷Remaining stations

Possible reason for Action or Limit Level Non-compliance

Outfall Shaft Area: marine construction activities, namely 1) N/A Intake Shaft Area: marine construction activities, namely 1) N/A Marine construction activities with contact with water: 1) N/A

Marine vessels on 04 February 2022:

-          N/A (Intake Shaft)

-          N/A (Outfall Shaft)

 

Dominating sea current direction was found to be from Southeast to Northwest at waters to the west side of Tit Cham Chau; and from Northeast to Southwest at waters to the east side of Tit Cham Chau.

 

Station WSR3 was located distant from the construction site and the possibility of being affected by marine construction activities was considered limited. SS exceedance was

however observed at WSR3 (6.8 mg/L). According to the construction work schedule provided by Main Contractor, no marine activities were conducted at both Intake and


 

 

Outfall shafts on 04 February 2022. All vessels were out of the Works area and no water pumping/ rock breaking work at Outfall on the day. Hence the SS exceedances at WSR3 maybe resulted from other natural factors.

 

According to the field observation by sampling team during sampling event, no silt plume was observed at the Contract site on 04 February 2022.

 

Conditions of the protective silt curtain at the inland water outfall was satisfactory on 04 February 2022.

According to the construction work schedule provided by Main Contractor, no marine construction work with contact with water was conducted at WSR36 (Intake Shaft) on 26 February 2022. SS exceedances were observed at WSR36 (5.5mg/L). Although concrete the Blinding layer inside the caisson was conducted at WSR37 (Outfall shaft) on 26 February 2022, the SS level at WSR37 (4.2mg/L) was lower than WSR36 (5.5mg/L), where WSR36 was located downstream during mid-ebb tide, which would be expected no cause of SS exceedance by the construction works at WSR37 (Outfall Shaft). WSR33 was also located downstream during mid-ebb tide, but the SS level at WSR33 (5.2mg/L) was similar to that at WSR36 (5.5mg/L). the observed SS exceedances maybe caused by other natural factors.

 

According to the field observation by sampling team during sampling event, no silt plume was observed at the Contract site on 26 February 2022.
