4. Monitoring Results

4.1 Noise Monitoring

Monitoring methodology

4.1.1 Monitoring Procedure

(a) The impact noise monitoring should be carried out at all the designated monitoring stations when there are project-related construction activities undertaken within a radius of 300m from the monitoring stations.

(b) The monitoring station shall normally be at a point 1m from the exterior of the sensitive receiver’s building façade and be at a position 1.2m above the ground.

(c) Façade measurements were made at the monitoring locations. For free-field measurement, a correction factor of +3 dB (A) would be applied.

(d) The battery condition was checked to ensure the correct functioning of the meter.

(e) Parameters such as frequency weighting, the time weighting and the measurement time were set as follows:

(f) Frequency weighting: A, Time weighting: Fast, Measurement time set: continuous 5 mins

(g) Prior and after to the noise measurement, the meter was checked using the acoustic calibrator for 94dB (A) at 1000 Hz. If the difference in the calibration level before and after measurement was more than ±1 dB (A), the measurement would be considered invalid and repeat of noise measurement would be required after re-calibration or repair of the equipment.

name of laboratory and equipment used and calibration details

4.1.2 Noise monitoring was performed using sound level meter at the designated monitoring locations. The sound level meters shall comply with the International Electrotechnical Commission Publications 651:1979 (Type 1) and 804:1985 (Type 1) specifications. Acoustic calibrator shall be deployed to check the sound level meters at a known sound pressure level. Brand and model of the equipment is given in Table 4.1.

4.1.5 The construction noise level shall be measured in terms of the A-weighted equivalent continuous sound pressure level (L_eq). L_{eq (30min)} should be used as the monitoring parameter. Supplementary information for data auditing, statistical results such as L₁₀ and L₉₀ shall also be obtained for reference.

4.1.6 For impact monitoring for construction of village sewers / rising main, noise monitoring should be undertaken on weekly basis. One set of L_{eq (30min)} noise level as six consecutive L_{eq (5min)} between 07:00-19:00 hours on normal weekdays.

4.2.9 In construction phase, the levels of dissolved oxygen (DO), temperature, turbidity and salinity should be measured in situ while suspended solids (SS) is determined by laboratory analysis.

MONITORING STATIONS

4.2.10 Water quality monitoring involves 6 monitoring stations. Reviewing the location of the outfall constructed under the scope of Contract DC/2020/02, water quality impact of the localized dredging works during construction phase can be effectively monitored around the nearfield stations SR4, SR5, SR15 within 500m radius of the outfall location and SR6 is already outside the 500m radius together with CE and CF can effectively act as control stations to monitor the extent of the dredging impact, whereas the farfield SR9, SR10 and SR12 are located at least 3km away from the sewage outfall location. As such, water quality monitoring at Station SR9, SR10 and SR12 were cancelled. The locations of water quality monitoring station are shown in Table 4.4.

Table 4.4 Marine Water Quality Stations for Water Quality Monitoring

Station	Description	Easting	Northing
CE	Upstream control station at ebb tide	810900	807690

Remarks (1): Fine adjustment of water quality monitoring stations at SR4, SR9 and SR12 was proposed as per EP Condition 3.1, and baseline monitoring was conducted at corresponding fine adjusted locations.

Monitoring date, time, Frequency and Duration

4.2.11 The levels of dissolved oxygen (DO), temperature, turbidity and salinity were measured in situ while suspended solids (SS) is determined by laboratory analysis at all the monitoring stations in Table 4.4 three times a week.

4.2.12 In association with the water quality parameters, other relevant data shall also be recorded, such as monitoring location / position, time, water temperature, DO saturation, weather conditions, and any special phenomena underway near the monitoring station.

4.2.13 Impact Monitoring shall be carried out three days per week, at mid-flood and mid-ebb tides (within ± 1.75 hour of the predicted time). The interval between two sets of monitoring shall not be less than 36 hours. The monitoring period should avoid concurrent marine project in the vicinity.

4.2.14 The sampling frequency of at least three days per week should be undertaken when the highest dust impact occurs. Upon completion of the construction works, the monitoring exercise at the designated monitoring locations should be continued for four weeks in the same manner as the impact monitoring. In case exceedance of Action/Limit Level is recorded, the frequency shall be increased as per the Event and Action Plan.

4.2.15 To ensure the robustness of in-situ measurement, parameters shall be measured in duplicate. In case the difference between duplicates is larger than 25%, a third set of measurement shall be carried out.
