In October 2015, Mott MacDonald Hong Kong Limited (MMHK) was commissioned by the Hsin Chong Construction Company Limited (the Contractor) to undertake the Environmental Team (ET) services (including environmental monitoring and audit (EM&A)) for the construction of M+ Museum Main Works at West Kowloon Cultural District (WKCD) (The Project) as part of the WKCD development. The Project Proponent is the West Kowloon Cultural District Authority (WKCDA). The construction works and EM&A programme commenced on 31 October 2015.

The overall works for the WKCD fall under two separate categories of Designated Project (DP) of the Environmental Impact Assessment Ordinance (EIAO), namely an “engineering feasibility study of urban development projects with a study area covering more than 20 ha or involving a total population of more than 100 000” (Item 3 of Schedule 3) and “an underpass more than 100m in length under the built areas” (Item A.9, Part I, Schedule 2). An Environmental Permit No. EP-453/2013/A (EP) was issued with respect to the “Underpass Road and Austin Road Flyover Serving the West Kowloon Cultural District” which specifically includes the abovementioned category of DP under Item A.9, Part I, Schedule 2 of the EIAO.

This Monthly EM&A Report is submitted under the approved EM&A Manual and summarises the findings on EM&A during the period from 31 October to 30 November 2015.

Exceedance of Action and Limit Levels

There was no breach of Action or Limit levels for Air Quality (1-hour TSP and 24-hour TSP) in this reporting month. Noise monitoring was suspected as permission and access to the podium level of the identified noise sensitive receivers could not be granted.

Implementation of Mitigation Measures

1 Introduction

1.1 Background

The M+ museum development aims to provide an iconic presence for the M+ museum, semi-transparent vertical plane, housing education facilities, a public restaurant and museum offices. At ground and lower levels, generous access will be provided to the park and other West Kowloon Cultural District facilities, alongside a public resource centre, theatres, retail and dining, and back-of-house functions. Basement of the M+ museum, which is part of the WKCD integrated basement consists of the underpass road.This report focuses on main works for M+ museum.

The Monthly EM&A Report is prepared in accordance with the Condition 3.4 of the Environmental Permit No. EP-453/2013/A. This Monthly EM&A Report presents the monitoring works conducted from 31 October

to 30 November 2015. The purpose of this report is to summarise the findings in the EM&A of the project over the reporting period.

1.2 Project Organisation

The organisation chart and lines of communication with respect to the on-site environmental management structure together with the contact information of the key personnel are shown in Appendix A.

1.3 Environmental Status in the Reporting Period

During the reporting period, construction works of the Project undertaken include:

¡ Site Formation

The Construction Works Programme of the Project is provided in Appendix B. A layout plan of the Project is provided in Figure 1. Please refer to Table 4.2 on the status of the environmental licenses.

1.4 Summary of EM&A Requirements

The EM&A programme requires environmental monitoring of air quality, noise, landscape and visual as specified in the approved EM&A Manual.

A summary of impact EM&A requirements is presented in Table 1.1.

Table 1.1: Summary of Impact EM&A Requirements

Parameters	Descriptions	Locations	Frequencies
Air Quality	24-Hour TSP	AM1 - International Commerce Centre	At least once every 6 days
	1-Hour TSP	AM1 - International Commerce Centre	At least 3 times every 6 days
	24-Hour TSP	AM2 - The Harbourside Tower 1	At least once every 6 days
	1-Hour TSP	AM2 - The Harbourside Tower 1	At least 3 times every 6 days
Noise	L_eq, 30 minutes	NM1- Podium level of The Harbourside Tower 1	Weekly
Landscape & Visual	Monitor implementation of proposed mitigation measures during the construction stage	As described in Table 9.1 and 9.2 of the EM&A Manual	Bi-weekly

Given that the Project covers only a small part of the whole WKCD area (i.e. M+ Museum, Lyric Theatre Complex and respective portions of underpass road), it was proposed that the EM&A programme for the Project should only require 1 noise monitoring station and 2 air quality monitoring stations located closest to the Project area. Other monitoring locations are too far away (i.e. AM3 to AM5 and NM2 to NM5) are not included in this EM&A programme until the construction of the corresponding area commences. The proposal of EM&A programme with details has been submitted to EPD on 2 December 2015 for consideration.

The Harbourside management office formally rejected our proposal of setting up air quality and noise monitoring equipment on its premises at the podium level of Tower 1 (AM2/NM1) on 10 November 2015. Alternative noise monitoring location was identified at The Arch (NM2), however The Arch management office formally rejected our proposal of setting up noise monitoring equipment on its premises on 23 November 2015. Correspondence from The Harbourside and The Arch management offices is attached in Appendix C for reference. Nevertheless, suitable air quality monitoring location at AM2 was identified on the ground floor in front of The Harbourside Tower 1 and noise monitoring at G/F of Harbourside will not be representative and thus NM1 will be suspended until permission and access is granted by The Harbourside management office. Therefore, 2 air quality monitoring stations were confirmed for the impact monitoring.

The Environmental Quality Performance Limits for air quality and noise are shown in Appendix D.

The Event and Action Plan for air quality, construction noise. landscape and visual are shown in Appendix E.

2 Impact Monitoring Methodology

2.1 Introduction

For air quality and noise, the monitoring methodology, including the monitoring locations, monitoring equipment used, monitoring parameters, and frequency and duration etc., for air quality and noise are detailed in this Section. The environmental monitoring schedules for the reporting period and the tentative monitoring Schedule for the coming month are provided in Appendix F.

For landscape and audit impact, the relevant EM&A monitoring requirements and details are also presented in this Section.

2.2 Air Quality

2.2.1 Monitoring Parameters, Frequency and Duration

Table 2.1 summarizes the monitoring parameters, frequency and duration of the TSP monitoring.

Table 2.1: Air Quality Monitoring Parameters, Frequency and Duration

Parameter	Frequency	Duration
24-hour TSP	At least once in every six-days	24 hours
1-hour TSP	At least 3 times every six-days	60 minutes

2.2.2 Monitoring Locations

The monitoring station was set up at the proposed location in accordance with updated EM&A Manual. Location of the monitoring station is given in Table 2.2 and shown in Figure 1.

Table 2.2: Air Quality Monitoring Station

Monitoring Station	Location
AM1	International Commerce Centre (ICC)
AM2	The Harbourside Tower 1

2.2.3 Monitoring Equipment

Continuous 24-hour TSP air quality monitoring was conducted using High Volume Sampler (HVS) (Model: TE-5170) located at the designated monitoring station. The HVS meets all the requirements stated in of the EM&A Manual. Portable direct reading dust meter was used to carry out the 1-hour TSP monitoring. Table 2.3 summarizes the equipment used in the impact air quality monitoring. Copies of the calibration certificates for the HVS, calibration kit and portable dust meters are attached in Appendix G.

Table 2.3: TSP Monitoring Equipment

Equipment	Model
24-hour TSP monitoring
High Volume Sampler	TE-5170 (Serial No.: 0767 and 8919)
Calibrator	TE-5025A (Serial No.: 0438320)
1-hour TSP monitoring
Portable direct reading dust meter	Sibata LD-3B (Serial No.: 2Z6240)

Calibration of the HVS (five point calibration) using Calibration Kit was carried out every two months. The HVS calibration orifice will be calibrated annually. Calibration certificate of the TE-5025A Calibration Kit and the HVS are provided in Appendix G.

The 1-hour TSP monitoring should be determined periodically (e.g. annually) by the HVS to check the validity and accuracy of the results measured by direct reading method.

2.2.4 Monitoring Methodology

24-hour TSP Monitoring

Installation

The HVS was installed at the site boundary. The following criteria were considered in the installation of the HVS.

– A horizontal platform with appropriate support to secure the sampler against gusty wind was provided.

– The distance between the HVS and any obstacles, such as buildings, was at least twice the height that the obstacle protrudes above the HVS.

– A minimum of 2 metres separation from walls, parapets and penthouse was required for rooftop sampler.

– A minimum of 2 metres separation from any supporting structure, measured horizontally was required.

– No furnace or incinerator flues or building vent were nearby.

– Airflow around the sampler was unrestricted.

– The sampler has been more than 20 metres from any drip line.

– Permission was obtained to set up the sampler and to obtain access to the monitoring station.

– A secured supply of electricity is needed to operate the sampler.

Preparation of Filter Papers

– Glass fibre filters were labelled and sufficient filters that were clean and without pinholes were selected.

– The filters used are specified to have a minimum collection efficiency of 99 percent for 0.3 µm (DOP) particles.

– All filters were equilibrated in the conditioning environment for 24 hours before weighing. The conditioning environment temperature was around 25 °C and not variable by more than ±3 °C with relative humidity (RH) < 50% and was not variable by more than ±5 %. A convenient working RH was 40%. All preparation of filters was done by Hong Kong Laboratory Accreditation Scheme (HOKLAS) accredited laboratory.

Field Monitoring Procedures

– The power supply was checked to ensure the HVS works properly.

– The filter holder and the area surrounding the filter were cleaned.

– The filter holder was removed by loosening the four bolts and a new filter, with stamped number upward, on a supporting screen was aligned carefully.

– The filter was properly aligned on the screen so that the gasket formed an airtight seal on the outer edges of the filter.

– The swing bolts were fastened to hold the filter holder down to the frame. The pressure applied should be sufficient to avoid air leakage at the edges.

– The shelter lid was closed and was secured with the aluminium strip.

– The HVS was warmed-up for about 5 minutes to establish run-temperature conditions.

– A new flow rate record sheet was set into the flow recorder.

– The flow rate of the HVS was checked and adjusted at around 1.3 m³/min. The range specified in the EM&A Manual was between 0.6-1.7 m³/min.

– The programmable timer was set for a sampling period of 24 hours, and the starting time, weather condition and the filter number were recorded.

– The initial elapsed time was recorded.

– At the end of sampling, the sampled filter was removed carefully and folded in half length so that only surfaces with collected particulate matter were in contact.

– It was then placed in a clean plastic envelope and sealed.

– All monitoring information was recorded on a standard data sheet.

– Filters were sent to a Hong Kong Laboratory Accreditation Scheme (HOKLAS) accredited laboratory for analysis.

Maintenance and Calibration

– The HVS and its accessories are maintained in good working condition, such as replacing motor brushes routinely and checking electrical wiring to ensure a continuous power supply.

– HVSs were calibrated upon installation and thereafter at bi-monthly intervals. The calibration kits were calibrated annually.

– Calibration records for HVS and calibration kit are shown in Appendix G.

1-hour TSP Monitoring

Field Monitoring

The measuring procedures of the 1-hour dust meter are in accordance with the Manufacturer’s Instruction Manual as follows:

– Turn the power on.

– Close the air collecting opening cover.

– Push the “TIME SETTING” switch to [BG].

– Push “START/STOP” switch to perform background measurement for 6 seconds.

– Turn the knob at SENSI ADJ position to insert the light scattering plate.

– Leave the equipment for 1 minute upon “SPAN CHECK” is indicated in the display.

– Push “START/STOP” switch to perform automatic sensitivity adjustment. This measurement takes 1 minute.

– Pull out the knob and return it to MEASURE position.

– Setting time period of 1 hour for the 1-hour TSP measurement.

– Push “START/STOP” to start the 1-hour TSP measurement.

– Regular checking of the time period setting to ensure monitoring time of 1 hour.

Maintenance and Calibration

– The 1-hour dust meter would be checked at 3-month intervals and calibrated at 1-year intervals throughout all stages of the air quality monitoring.

– Calibration records for direct dust meters are shown in Appendix G.

Weather Condition

– Meteorological data extracted from Hong Kong Observatory for the reporting month is provided in Appendix I.

2.3 Noise

The Harbourside management office formally rejected our proposal of setting up noise monitoring equipment on its premises at the podium level of Tower 1 (NM1) on 10 November 2015. Alternative noise monitoring location was identified at The Arch (NM2), however The Arch management office formally rejected our proposal of setting up noise monitoring equipment on its premises on 23 November 2015. Since noise monitoring at G/F of Harbourside will not be representative and thus NM1 is being suspended until permission and access is granted by The Harbourside management office.

2.4 Landscape and Visual

2.4.1 Monitoring Program

Table 2.4 details the monitoring program (as proposed in the WKCD EIA report) for landscape and visual impact during the construction phase.

Table 2.4: Monitoring Program for Landscape and Visual Impact during Construction Phase
