3        Construction Noise Monitoring

3.1        Monitoring Requirements, Frequency and Duration

Construction noise is one of the key environmental issue during the construction phase of the Project in accordance to the approved EM&A Manual. Following the requirements in the EM&A Manual, continuous noise monitoring for A-weighted levels Leq, L10, L90 shall be undertaken once every week during the construction phase. Measurement of Leq(30min) between 07:00-19:00 hours on normal weekdays.

If construction works are necessary to carry out at other time periods, i.e. restricted time period (19:00-07:00 the next morning and whole day on public holidays) (hereinafter referred as “the restricted hours”), 3 consecutive Leq(5min) measurements shall be recorded, while complying specific conditions as stipulated on the Control Noise Permit (CNP). Supplementary information for data auditing, statistical results such as L10 and L90 shall also be obtained for reference. Summary of these monitoring requirements is listed in Table 2.

Table 2: Noise Monitoring Parameters

NM1A and NM2

      Leq(30min) in normal working days (Monday to Saturday) 07:00-19:00 except public holiday;

      3 sets of consecutive Leq(5min) on restricted hours i.e. 19:00 to 07:00 next day, and whole day of public holiday or Sunday when applicable, and

      Supplementary information for data auditing, statistical results such as L10 and L90 shall also be obtained for reference

The baseline results form the basis for determining the environmental acceptance criteria for the impact monitoring. According to the approved EM&A Manual with baseline monitoring results, construction noise criterion, namely Action and Limit levels proposed are listed in Table 3.

Note:      1. Acceptable noise levels for school should be reduced to 65 dB(A) during examination period
2. If works are to be carried out during restricted hours, the conditions stipulated in the CNP have to be followed.

3.2        Monitoring Locations

Two designated noise monitoring locations as established in the EM&A Manual is shown in Appendix D.  After the baseline monitoring, alternative location NM1A has been proposed by MMHK due to rejection of the monitoring location set up at NM1. The proposal was verified and agreed by EPD in the Baseline Monitoring Report.

Table 4 and Appendix E respectively list and show the construction noise monitoring locations for the Project.

3.4        Monitoring Methodology

Field Monitoring

    Sound Level Meter was set on a tripod at a height of at least 1.2m above ground.

    Noise measurements were taken in terms of the A-weighted equivalent sound pressure level (Leq) measured in decibels (dB). Supplementary statistical results (L10 and L90) were also obtained for reference.

    Free field measurement was made at NM1A while facade measurement was made at NM2.

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

    Prior of and after each noise measurement, the meter is calibrated using an acoustic calibrator for 94dB at 1kHz. The checking is performed before and after the noise measurement.

    During the monitoring, all noise measurements would be performed with the meter with Fast time weighting and on the A-weighted equivalent continuous sound pressure level (Leq). Leq(30min) as the monitoring parameter for the time period between 0700-1900 hours on weekdays; and also Leq(15min) in three consecutive Leq(5min) measurements would be used as monitoring parameter for other time periods (e.g. during restricted hours), if necessary. In addition, any site observations and noise sources were recorded on a standard record sheet.

    A correction of +3dB(A) was made to the free field measurement.

    Noise measurements were not made in fog, rain, wind with a steady speed exceeding 5ms-1 or wind with gust exceeding 10ms-1.

Equipment calibration

    The sound level meter and calibrator are calibrated and certified by a HOKLAS accredited laboratory at yearly intervals.

    Calibration records of sound level meter and calibrator, together with the Anemometer used for impact monitoring program in the Reporting Period are shown in Appendix F.

Meteorological Information

Meteorological information was extracted from “the Hong Kong Observatory Wong Chuk Hang Station” to provide the humidity, wind speed, wind direction and temperature etc. as background weather information. The meteorological data throughout the impact monitoring period is summarized in Appendix K.

Derivation of Action/Limit (A/L) Levels

According to the approved EM&A Manual and baseline monitoring results, Action and Limit levels proposed on construction noise criterion monitoring are listed in Table 6.

Note:    1. A correction of +3dB(A) was made to the free field measurement at monitoring station NM1A.
2. Limit level of the construction noise monitoring for school was reduced to 65 dB(A) during examination period at HKJCC on 14th June to 20th June.

Should non-compliance of the environmental quality criteria occurs, remedial actions will be 
triggered according to the Event and Action Plan which presented in
Appendix G. 

Data Management and Data QA/QC Control 

All monitoring data will be handled by the ET’s in-house data recording and management system. The monitoring data recorded in the equipment will be downloaded directly from the equipment at the end of each monitoring day.  The downloaded monitoring data will input into a 
computerized database properly maintained by the ET. 

3.5        Monitoring Schedule

Monitoring for noise levels due to construction work was undertaken during the reporting month in compliance with the EM&A manual in the reporting period. Regular monitoring surveys were carried out on 7th, 14th, 22nd and 28th June 2017 during the reporting month to access the compliance with environmental requirements. A total of 8 occasions of noise monitoring surveys were carried out at the two noise monitoring locations.

3.6        Results of Impact Monitoring

As shown in Table 7, results of the noise monitoring measurement were below 70bB(A), or 65dB(A) for examination period. No noise complaints were received in this reporting period. No exceedance (Action/Limit Level) of construction noise was thus recorded in this period.

Note:      1. A correction of +3dB(A) was made to the free field measurement at monitoring station NM1A.
2. Limit level of the construction noise monitoring for school was reduced to 65 dB(A) during examination period at HKJCC on 14th June to 20th June.

Summary of data and the supplementary information for data auditing is presented in Appendix I. Graphical plots of the monitoring data are as shown in Appendix J.


4        Ecology Monitoring

4.1        General

As required under the Section 8.3.2 of the approved EM&A Manual, the implementation of ecological mitigation measures as detailed in the Section 15 of the EIA report and Appendix C of the approved EM&A Manual shall be routinely audited during the routine environmental audit; and any observations and recommendations shall be reported in periodic EM&A reports.

Among those mitigation measures recommended to avoid or minimize the disturbance to any plants of conservation interest (EM&A reference, nested ardeids (EM&A reference and roosted short-nosed fruit bat (EM&A reference, the required inspection has already been undertaken in August/September 2014 with the results presented in the submitted respective baseline report.  Therefore, the following sections only address those applicable to this stage of the project, i.e., Section 8.3.2 of the approved EM&A Manual.

4.2        Monitoring Requirement

Monitoring of Plants of Conservation Interest (Platycondon grandiflorus) 

According to Condition 2.6 of Environmental Permit No. EP-487/2014, The Detailed Vegetation Survey Report has located two groups of the protected Platycodon grandiflorus and recommended that the plants should be protected with temporary protective fencing to avoid potential impact from construction activities (such as material storage), and monitor the identified Platycodon grandiflorus on a monthly basis throughout the construction phase to make sure that they are not affected by the construction works of the Project. Accordingly, the following monitoring parameters will be undertaken on a monthly basis during the construction period.

    Effective implementation of the protection measures as recommended in the Section 4.1 of the Detailed Vegetation Survey Report 

    Monitoring of the two groups of Platycodon grandiflorus identified during the detailed vegetation survey to make sure that they are not affected by the construction works

Monitoring of Nesting Activities of Ardeids in Breeding Season

The project area should be checked monthly in breeding season (April to July) for any potential breeding and nesting activities, and if required suitably sized buffer area will be recommended to avoid human or machinery disturbance until the nest is abandoned.

Monitoring of Roosting Activities of Ardeids in Peak Wintering Season

The existing ardeid night roost within the project area should be monitored monthly during peak wintering season (November to March) during the construction phase using direct observation from a vantage point (i.e., point count method) at evening time from an hour before sunset, and last until the nightfall.

Compensation for Ardeid roosting Site

An enhancement area provided as an alternative roosting site for ardeids should be developed during the first phase of the construction.

Compensation of Woodland Habitat

Mitigation measures recommended in the approved Woodland Compensation Plan should be fully and properly implemented, including but not limited to the creation of 0.84 ha woodland compensation on-site and 0.78 ha on-site woodland reinstatement, to mitigate for permanent loss of woodland habitat.

4.3        Inspection Findings

The ecological inspection was undertaken on 14 June 2017 by the qualified ecologist. The inspection findings are presented below.

Plants of Conservation Interest (Platycondon grandiflorus)

Platycodon grandiflorus is a perennial herb and up to 120 cm high. Stems erect and scarcely any branches. It is often found on sunny grassy hillslopes in brushes. Two groups of Platycodon grandiflorus (see Figure 1 of Appendix L for their locations) were recorded in the 2015s’ growing season within the fenced area were found to be healthy without in the reporting month (see Photos 1 and 2 of Appendix L of this report).

On the other hand, the preventive mitigation measures, i.e., erecting of temporary protective fencing and sign post, are found to be effectively implemented (see Photo 3 of Appendix L of this report), and there is no signs or evidence (e.g. dust coating of plant) to suggest that the on-going construction activities within the Project Area has affected the health condition of the Platycodon grandiflorus.

Nesting Activities of Ardeids in Breeding Season
