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 L_eq, L₁₀, L₉₀ shall be undertaken once every week during the construction phase. Measurement of L_eq(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 L_eq(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

Monitoring Station	Parameters
NM1A and NM2	● L_eq(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

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.

Calibrator	Larson Davis CAL200
Portable Wind Speed Indicator	Anemometer/ Lutron AM-4201

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 (L_eq) 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 (L_eq). L_eq(30min)as the monitoring parameter for the time period between 0700-1900 hours on weekdays; and also L_eq(15min)in three consecutive L_eq(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.

Table 6: Action and Limit Levels for Construction Noise

Monitoring Location	Action Level	Limit Level in dB(A)
	Time Period: 07:00-19:00 hours on normal weekdays
NM1A and NM2	When one or more documented complaints are received	70 dB(A) ^{1, 2}

Note: 1. A correction of +3dB(A) was made to the free field measurement at monitoring station NM1A.
2. No examination has taken place during this reporting month.

Should non-compliance of the environmental quality criteria occur, 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 5^th, 12^th, 19^th and 27^th July 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). No noise complaints were received in this reporting period. No exceedance (Action/Limit Level) of construction noise was thus recorded in this period.

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 8.3.1.1), nested ardeids (EM&A reference 8.3.1.2) and roosted short-nosed fruit bat (EM&A reference 8.3.1.3), 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 21 July 2017 by the qualified ecologist. The inspection findings are presented below.

Plants of Conservation Interest (Platycondon grandiflorus)

Platycodon grandiflorus is a perennial herb 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) that were recorded in 2015’s 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, were 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

No signs or breeding (such as courtship, nest building, brooding, juveniles etc.) of ardeids were noted within the project area during the reporting month.

Roosting Activities of Ardeids in Peak Wintering Season.

In accordance with the approved EM&A Manual, this monitoring parameter would not be required beyond the Peak Wintering season, i.e., from 1^st November to 31^st March.

Compensation for Ardeid roosting Site

To be implemented.

Compensation of Woodland Habitat

To be implemented.

4.4 Conclusion

The implementation of the mitigation measures for the plant species of conservation interest, i.e., the Platycodon grandiflorus, was found to be effective during the reporting period and no sign of activities related to construction work was noted within or in proximity of the fenced up area. The growth of the two groups of Platycodon grandiflorus within the fenced area were found to be vigorous and all of the shoots were all in healthy condition.

On the other hand, no sighting of ardeids or signs of any breeding/nesting activities were noted within the project area during the monitoring.

The tentative ecological inspection and monitoring in the next reporting period is scheduled on 25 August 2017.

9 Implementation Status of Mitigation Measures

9.1 General Requirements

The environmental mitigation measures that were recommended in the Implementation Schedule for Environmental Mitigation Measures in the approved EM&A Manual covered the issues of dust, noise, water and waste and are presented in Appendix N.

The Project shall be implementing the required environmental mitigation measures according to the approved EM&A Manual as subject to the site condition. Environmental mitigation measures generally implemented by the Contractor in this Reporting Month are summarized in Table 10.

Table 10: Environmental Mitigation Measures

Issues	Environmental Mitigation Measures
Construction Noise	● Shut down construction equipment when not using
Ecology	● Wire fencing provided for temporary protect the identified flora species of conservation concern ● Undertake site inspection of the flora species of conservation and the Ardeid of breeding and nesting activities
Landscape & Visual	● Good site management
Air Quality	● Good site management to reduce air quality impact ● Main temporary access road paved with concrete ● Prior to any loading or transfer operation, all dusty materials has sprayed with water to keep its wet ● Any debris has covered entirely by impervious sheeting ● Before debris dumped into a chute, water has sprayed onto the debris to make its wet ● Vehicles has covered with tarpaulin during transporting dusty materials ● When vehicles leaving the construction site, any vehicles loaded dusty materials covered with clean impervious sheeting as prevent fugitive dusty materials emission ● The speed of the trucks passing site areas was controlled to below 10 km/hour ● Water spray has been provided for soil-nailing work
Water Quality	● Portable chemical toilets have provided on site ● A licensed collector has employed to collect effluent and off-site dispose.
Waste and Chemical Management	● A temporary container which located far away from sea shore and drainage channel, has provided for chemical materials and waste storage ● Drip tray is provided for chemical materials which use on the working areas ● Has provided a waste skip for general refuse disposal
General	● The site was generally kept tidy and clean

9.3 Key Issues for the Coming Month

Based on construction activities as undertaken in the coming month, key environment issues consider to be included:

● Potential fugitive dust impact due to the dry/loose/exposure soil surface/dusty material;

● Potential water quality impact due to surface runoff;

● Implement dust suppression measures at the all times;

● Ensure noise and dust mitigation measures are implemented properly;

● Sediment catch-pits and silt removal facilities should be regularly maintained;

● Site effluent discharge shall be fulfilled the discharge license requirements;

● Management of chemical wastes properly implement;

● Follow-up of improvement on general waste management issues; and

● Implementation of construction noise preventative control measures.

10 Recommendation

● All drainage facilities, erosion and sedimentation control structures (including the sedimentation tanks installed on site) should be regularly inspected and maintained in good condition, especially during the wet season.

● Noise mitigation measures, including the use of quiet plants, should be implemented in accordance with the EM&A requirement.
