3 Construction Noise Monitoring

3.1 Monitoring Requirements, Frequency and Duration

Construction noise is one of the key environmental issues 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 per 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 be carried 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”), three consecutive L_eq(5min)measurements shall be recorded, while complying specific conditions as stipulated on the Construction Noise Permit (CNP). Supplementary information for data auditing and statistical results such as L₁₀ and L₉₀ shall also be obtained for reference. Summary of these monitoring requirements is shown in Table 2.

Table 2: Noise Monitoring Parameters

Monitoring Station	Parameters
NM1A and NM2	● L_eq(30min)on normal working days (Monday to Saturday) 07:00-19:00 except public holiday; ● 3 sets of consecutive Leq(5min) during 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 and 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 must 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.

The construction noise monitoring locations for the Project are shown in Table 4 and Appendix E

Table 4: Impact Monitoring locations

Monitoring location	Descriptions	Type of measurement
NM1A	Slope near Victoria Shanghai Academy (VSA) to replace NM1 of the VSA	Free field

3.3 Monitoring Equipment

Integrating sound level meter in compliance with the International Electrotechnical Commission Publications 651: 1979 (Type 1) and 804: 1985 (Type 1) specifications shall be used for carrying out the noise monitoring. The sound level meter shall be checked using an acoustic calibrator. The wind speed shall be checked with a portable wind speed meter capable of measuring the wind speed in ms^-1. The acoustic calibrator and sound level meter to be used in the impact monitoring will be calibrated yearly.

Noise monitoring equipment used for monitoring is listed in Table 5.

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

3.4 Monitoring Methodology

Field Monitoring

● Sound Level Meter was set up on a tripod at a height of at least 1.2 m 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 to and after each noise measurement, the meter was calibrated using an acoustic calibrator for 94 dB at 1 kHz. The checking was 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 +3 dB(A) was made to the free field measurement.

● Noise measurements were not made in fog, rain, wind with a steady speed exceeding 5 ms^-1 or wind with gust exceeding 10 ms^-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 criterion proposed for construction noise 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 period.

Should non-compliance of the environmental quality criteria occur, remedial actions will be
triggered according to the Event and Action Plan which is 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 be inputted into a computerized database properly maintained by the ET.

3.5 Monitoring Schedule

Monitoring for noise levels due to construction work was undertaken in compliance with the EM&A manual during the Reporting Period. Regular monitoring surveys were carried out on 4, 10, 19 and 26 April 2018 during the Reporting Period and three additional impact monitoring for the construction works held during restricted hour period on 1, 8, 15, 22 and 29 April 2018 to access the compliance with environmental requirements. A total of eighteen 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 70 dB(A). No noise complaints were received in this Reporting Period. No exceedance (Action/Limit Level) of construction noise was 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 ensure 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 ensure 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 by direct observation from a vantage point (i.e., point count method) in the evening from an hour before sunset to nightfall.

Compensation for Ardeid roosting Site

An enhancement area proposed 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 13 April 2018 by the qualified ecologist. The inspection findings are presented below.

Plants of Conservation Interest (Platycodon grandiflorus)

Platycodon grandiflorus is a perennial herb up to 120 cm tall. Stems erect with 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.

On the other hand, the preventive mitigation measures, i.e., erecting of temporary protective fencing and sign post, were found to be effectively implemented for human disturbance (see Photo 3 of Appendix L of this report), and there are no signs or evidence (e.g. dust coating of plant) to prove that the on-going construction activities within the Project Area has affected the health condition of the Platycodon grandiflorus. The new shoots were observed from the underground part in Reporting Period (see Photos 1 and 2 of Appendix L of this report).

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 1st November to 31st March. The last monitoring event for roosting activities of ardeids in Peak Wintering Season 2018’s was undertaken on 16 March 2018.

5 Landscape & Visual Monitoring

5.1 General

Landscape and visual mitigation measures for the construction phase are listed in the Approved EM&A Manual Table 9.1.

The design, implementation and maintenance of landscape and visual mitigation measures shall be checked bi-weekly to ensure that they are fully realized during the construction phase. The scope of the site audit during construction shall include the following:

● The extent of the agreed works areas should be regularly checked. No construction activities or storage shall be undertaken outside the limit of the works;

● The progress of the engineering works should be regularly reviewed on site to identify the earliest practical opportunities for the landscape works to be undertaken;

● All landscaping works are carried out in accordance with the specifications; and

● All new plantings are carried out properly and during the right season.

Any potential conflicts between the proposed landscape and visual mitigation measures and any other project works or operational requirements shall be recorded for the Contractor to resolve in an early stage, without compromising the intention of the mitigation measures.

5.2 Inspection Findings

In the Reporting Period, bi-weekly landscape and visual site inspections were conducted on 6 and 20 April 2018.

According to the bi-weekly site inspections, it was observed that the Contractor complied with the intended aims of the mitigation measures, for example, neither construction activities nor materials storage conducted and placed outside of the working site boundary.

6 Waste Management

6.1 General Waste Management

Waste management was carried out by an on-site Environmental Officer or an Environmental Supervisor from time to time.

6.2 Records of Waste Quantities

All types of waste arising from the construction work are classified into the following:

● Construction & Demolition (C&D) Material;

● Chemical Waste;

● General Refuse; and

● Excavated Soil.

Monthly Summary Waste Flow Table provided by the Contractor is shown in Appendix M. Materials were reused on-site as far as practicable.

7 Site Inspection

7.1 Requirements

According to the approved EM&A Manual, the environmental site inspection shall be formulated by the ET Leader. Weekly environmental site inspections should be carried out to confirm the environmental performance.

7.2 Findings / Deficiencies During the Reporting Period

During site inspections, non-compliance was not observed by the ET and IEC. However, a total of three observations were recorded in the Reporting Period. The findings / deficiencies of the Project observed during the weekly site inspections are listed in Table 9.

Table 9: Summary of findings / deficiencies

Date	Findings / Deficiencies	Follow-up Status
13 Apr 2018	Fugitive dust was observed, appropriate mitigation measures should be undertaken.	Mitigation measures (water spraying) for fugitive dust were undertaken and the mixing shelter was removed.
20 Apr 2018	Chemical and oil containers observed without drip tray at L1 corridor next to EVA, at L2 next to EVA and L3.	Drip tray has been provided for chemical container at L1 near EVA and the chemical container were removed from the area at L2 next to EVA L3
27 Apr 2018	Oil container observed without drip tray at L2 grout station	The chemical container without drip tray was removed from L2 grout station

The Contractor has rectified the above deficiencies immediately or within deadline. Therefore, the environmental performance of the Project managed by the Contractor with OPC was considered satisfactory.

Special attention shall be paid on the proper implementation of mitigation measures to prevent runoff flow to public area.

As a general reminder, dust mitigation measures should be enforced to prevent fugitive dust from haul road, idle slope work and construction activities; and the site tidiness should be maintained. Furthermore, all chemical materials shall be stored in the designated area after use with drip tray.

8 Environmental Complaint, Summons and Prosecution

8.1 Environmental Complaint, Summons and Prosecution

No environmental complaint, summons and prosecution were received in the Reporting Period.

The statistical summary for environmental complaints is presented in Table 10.

Table 10: Statistics for complaints, notifications of summons and successful prosecutions

Reporting Period	Cumulative Statistics
	Complaints	Notifications of summons	Successful prosecutions
This report month	0	0	0

The complaints received in relation to the environmental impact during March 2018 was investigated as follows:

Case 1: The complaint was about noise generated by construction equipment and construction vehicles movement at midnight from the construction site of Ocean Park Tai Shue Wan Water World Project.

Result of investigation:

As informed by the Contractor:

● As Shum Wan Road, the only access to the construction site, experienced congested traffic during daytime, the planned concreting works had been extended beyond 19:00.

● Referring to the information provided by the site team, no works was carried out during the incident period.

● It is noted that the Contractor obtained a valid Construction Noise Permit (CNP No. CW-RS1024-17) permitting the use certain powered mechanical equipment (PME) including PME for concreting works during restricted hours between 23 November 2017 and 16 May 2018. The listed PME and no. of units have been strictly followed to CNP.

This complaint is unlikely to be related to the construction works on the project site due to no construction works was carried out during the incident period.

Case 2: The complaint was about traffic noise at Nam Long Shan Road related to Ocean Park night time operation.

According to the complainant, construction vehicles travelled along Nam Long Shan Road in the direction of Ocean Park for the past few years between the hours of 01:00 and 04:00. Furthermore, the complaint suspect that some of the vehicles were garbage trucks but according to FEHD’s reply, no garbage pick-up was conducted during this period.

Result of investigation:

As informed by the Contractor:

● No construction vehicles were accessed from Nam Long Shan Road to Project Site since the commencement of this contract (TSW-C006).

● The site entrance at Nam Long Shan Road leading to the upper part of the sewage rising main under this project. However, there are no night works for this area since the commencement of this contract (TSW-C006).

Based on the above information, the complaint is considered unlikely to be related to the construction works at the project site.
