1.1
Background
In October 2015, Mott MacDonald Hong Kong Limited (MMHK) was commissioned 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. The captioned project (i.e. The M+ Museum Mian Works at WKCD) includes part of the abovementioned underpass road located within the site boundary also falls under this same category.
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 1 February to 29 February 2016. The purpose of this report is to summarise the findings in the EM&A of the project over the reporting period.

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. Currently, the works under the captioned project are confined in the western part of the WKCD site. Therefore, only the monitoring stations AM1, AM2 and NM1 were set up. 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 revised proposal of EM&A programme with details has been submitted to EPD on 20 January 2016 for consideration and futher comments was received on 29 January 2016. The preparation of response to comments is in progress.
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, which is at the same location as that of baseline monitoring for consistency. No management approval is required at the ground floor for conducting the air monitoring and a secure electricity supply is available there. 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. However, approval from the management office of the International Commerce Centre has been granted on 29 February 2016 for conducting noise monitoring at the alternative noise monitoring location identified at the podium floor (NM1A) which is free from screening to the construction activities. Therefore, 2 air quality monitoring stations were confirmed for the impact monitoring and 1 noise impact monitoring station will be included for impact monitoring starting from March 2016. The noise monitoring results will be reported in the next reporting month.
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.
The EM&A programme followed the recommended mitigation measures in the EM&A Manual. The EM&A requirements as well as the summary of implementation status of the environmental mitigation measures are provided in Appendix K.

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 ΅m (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 Manufacturers 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
Currently, the works under the captioned project are confined in the western part of the WKCD site. Therefore, only the monitoring station NM1 was set up. However, 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. However, approval from the management office of the International Commerce Centre has been granted on 29 February 2016 for conducting noise monitoring at the alternative noise monitoring location identifed. The noise monitoring will commence in March 2016 and the monitoring results will be reported in the next reporting month.

Recommended Mitigation Measures
The EM&A programme followed the recommended mitigation measures in the EM&A Manual. The EM&A requirements as well as the summary of implementation status of the environmental mitigation measures are provided in Appendix K. In particular, the following mitigation measures were brought to attention during the site inspections:
Chemical and Waste Management
All chemicals store on site should be provided with drip trays.
Drip trays should be kept in good condition.
Chemical waste in drip trays should be frequently removed and ensure no leakage of oil/ chemicals from machines.
Chemical labels should be provided to all chemicals stored on site.
Air Quality
Stockpiles of cement and other construction materials should be kept covered when not being used.
Maintain high standard of housekeeping to prevent emission of fugitive dust.
Water Quality
Silty effluent should be treated/ desilted before discharged. Untreated effluent should be prevented from entering public drain channel.
Stagnant water in site area should be cleared.
The capacity of the wetsep should be reviewed to avoid overflow problem.
Dust suppression spraying for stockpile should be applied appropriately to avoid any leakage of spraying from the site.
No leakage of site runoff from the site near site boundary should be ensured.

7.1
Conclusions
The EM&A programme as recommended in the EM&A Manual has been undertaken since the construction works commenced on 31 October 2015.
Monitoring of air quality with respect to the Project is underway. In particular, the 1-hour TSP, 24-hour TSP under monitoring have been checked against established Action and Limit levels. There was no breach of Action and Limit Levels for 1-hour TSP, 24-hour TSP in the reporting month. Noise monitoring was suspended as the permission and access at podium of the identified noise sensitive receiver could not be granted. However, approval from the management office of the International Commerce Centre has been granted on 29 February 2016 for conducting noise monitoring at the alternative noise monitoring location identifed. The noise monitoring will commence in March 2016 and the monitoring results will be reported in the next reporting month.No environmental complaint and no notifications of summons or successful prosecution were received during the reporting month.
Weekly construction phase site inspections and bi-weekly landscape and visual impact inspections were conducted during the reporting month as required. It was observed that the Contractor had implemented all possible and feasible mitigation measures to mitigate the potential environmental impacts during construction phase works.
7.2
Recommendations
Potential environmental impacts due to the construction activities, including air quality, noise, water quality, waste, landscape and visual, will be monitored or reviewed. The recommended environmental mitigation measures shall be implemented on site and regular inspections as required will be carried out to ensure that the environmental conditions are acceptable.
