1.1
Background
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 (Contract No.: CC/2015/3A/022) and Lyric Theatre Complex Foundation Works (Contract No.: CC/2015/3A/014) 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 for M+ Museum and Lyric Theatre Complex commenced on 31 October 2015 and 1 March 2016 respectively.
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 projects include 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.
The 1,200-seat Lyric Theatre Complex will be Hong Kongs first world-class facility for dance performances, including ballet, contemporary and Chinese dance forms. In the run up to the opening of further major performing arts venues in the WKCD, it will also be used for a wide variety of performing arts events including drama, opera and musical performances. The Lyric Theatre Complex will act as a platform for Hong Kongs leading arts organisations, and be a new major venue to show programmes from Asia and worldwide.
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 at both the main works of M+ Museum and foundation works of Lyric Theatre Complex conducted from 1 July to 31 July 2016. The purpose of this report is to summarise the findings in the EM&A of the project over the reporting period.

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.

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 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. 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. 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 and 1 noise impact monitoring station were confirmed for the impact monitoring.
The Environmental Quality Performance Limits for air quality and noise are shown in Appendix C.
The Event and Action Plan for air quality, construction noise. landscape and visual are shown in Appendix D.
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 J.

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 F.

Monitoring
Methodology
Field Monitoring
The microphone of the Sound Level Meter was set at least 1.2 m above the ground.
Free Field measurement was made at the monitoring locations.
The battery condition was checked to ensure the correct functioning of the meter.
Parameters such as frequency weighting, the time weighting and the measurement time were set as follows:
- frequency weighting: A
- time weighting: Fast
- time measurement: 30 minutes intervals (between 0700-1900 on normal weekdays)
Prior to and after each noise measurement, the meter was calibrated using a Calibrator for 94 dB at 1 kHz. If the difference in the calibration level before and after measurement was more than 1 dB, the measurement would be considered invalid and has to be repeated after re-calibration or repair of the equipment.
During the monitoring period, the Leq, L10 and L90 were recorded. 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 measurements.
Maintenance and Calibration
The microphone head of the sound level meter and calibrator is cleaned with soft cloth at quarterly intervals.
The sound level meter and calibrator are sent to the supplier or HOKLAS laboratory to check and calibrate at yearly intervals.
Calibration records are shown in Appendix F.
