Introduction
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 including the Foundation Works (Contract No.: CC/2015/3A/014) and L1 Contract (Contract No. CC/2017/3A/030) 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/B (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 Quarterly EM&A Report is prepared in accordance with the Clause 3.4 of the Environmental Permit No. EP-453/2013/B. This Quarterly EM&A Report presents the monitoring works conducted from 1 February 2019 to 30 April 2019. 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 were set up. However, the electricity supply at AM2 was suspended from 31 August 2016 and was no longer available. In order to have a more secure electricity supply, an alternative air monitoring location (AM2A) was identified at Austin Road West opposite to The Harbourside Tower 1, which is close to Lyric Theatre Complex site entrance. This alternative air monitoring location was approved by EPD on 28 September 2016. Due to works programme, the air monitoring location AM2A has been relocated to the alternative monitoring location AM2B at the 1st floor of Gammons site office, which was approved by EPD on 21 February 2019. Meanwhile, the opportunity of setting up the air monitoring location at The Harbourside is being explored. 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.

Environmental Non-conformance
On 4 February 2019, an exceedance of 24-hr TSP was recorded at monitoring station AM2A. The measured level was at 207 ΅g/m3 while the action level is at 151.1 ΅g/m3. The contractors, IEC and ER were informed of the exceedance. Investigation has been carried out and it is revealed that the contractors of M+ Museum and Lyric Theatre Complex have already implemented dust mitigation measures to reduce the dust impact from their construction works. An observation regarding not providing water spraying for handling dusty materials was recorded during the environmental site inspection at Lyric Theatre Complex on 4 Feb 2019. But the contractor had immediately rectified the observation within 5-10 minutes of noticing this observation, so it is deemed that the contribution to the exceedance was minor. Moreover, it should be noted that there was open trench excavation carried out by another contractor at Austin Road West on 4 Feb 2019, but no dust mitigation measures were provided. This may also have contributed to the 24-hr TSP exceedance during the concerned monitoring period. Nonetheless, the contractors were reminded to strengthen the implementation of the recommended dust control measures.
There was no breach of Limit Level for Air Quality and Action or Limit Levels for Noise monitoring in the reporting month.
No environmental complaints and no notifications of summons or successful prosecution were received in the reporting quarter.
The cumulative statistics on complaints, notifications of summons and successful prosecutions were provided in Appendix G.

Comments, Recommendations and Conclusion
6.1
Comments
Based on the observations made during site audits and landscape inspections, and construction dust and noise monitoring results, no non-compliances and exceedances of air quality and noise limits were recorded.
6.2
Recommendations
Reviewing the implementation of the recommended mitigation measures in the EM&A Manual, it was observed that they were effective and efficient in controlling the potential impacts due to construction of the project during the reporting period. Review of the effectiveness and efficiency of the EM&A programme will continue, and recommendations will be provided to remediate any potential impacts due to the project and to improve the EM&A programme if deficiencies of the existing EM&A programme are identified.
6.3
Conclusion
The EM&A programme as recommended in the EM&A Manual has been undertaken since the construction works of M+ Museum main works commenced on 31 October 2015, and the construction of Lyric Theatre Complex commenced on 1 March 2016.
Monitoring of air quality and noise with respect to the Project is underway. In particular, the 1-hour TSP, 24-hour TSP, noise level (as Leq, 30 minutes) under monitoring have been checked against established Action and Limit levels. One exceedance of Action Level of 24-hour TSP for Air Quality were recorded. There was no breach of Limit levels for Air Quality (1-hour TSP and 24-hour TSP) and Noise in this reporting quarter.
No environmental complaint was received during the reporting quarter. No notification of summons and no successful prosecution were received during the reporting quarter.
Weekly construction phase site inspections and bi-weekly landscape and visual impact inspections were conducted during the reporting quarter 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.
