EXECUTIVE SUMMARY

i. This Quarterly Environmental Monitoring and Audit (EM&A) Summary Report is prepared for Contract No. SPW 07/2020 “Environmental Team for Construction of Yuen Long Effluent Polishing Plant Stage 1”. Drainage Services Department (DSD) has appointed Fugro Technical Services Limited (FTS) to undertake the Environmental Team services for the project and implement the EM&A works.

ii. This is the 2nd Quarterly EM&A Summary Report for the Contract which summaries findings of the EM&A programme during the reporting period from 1 July 2021 to 30 September 2021. As informed by the Contractor, major activities in the reporting period shown in section 1.4.1.

iii. The EM&A methodology has been effective in monitoring the environmental impacts of the Project and the effectiveness of the mitigation measures. The data collected were useful in determining whether the Project had caused unacceptable impacts on the sensitive receivers. Analysis of all EM&A data collected throughout the baseline and the impact periods demonstrated the environmental acceptability of the Project.

Breaches of Action and Limit Levels

iv. No Action and Limit Level exceedance was recorded for air quality monitoring and construction noise monitoring in the reporting period.

v. No Action Level exceedance but three (3) Limit Level exceedances were recorded for water quality in the reporting period. It was found that these exceedances were not project-related.

vi. No Action / Limit exceedance was recorded for noise levels at stations (NMS1 and NMS2) in close proximity to the active ardeid night roosts during the monitoring period.

vii. A total of two (2) Action Level exceedances were recorded for the ecological monitoring of birds during the reporting period. However, these exceedances were not project-related.

Land Contamination

viii. Regular site inspection was carried out to ensure the recommended mitigation measures are properly implemented. No specific observation associated with land contamination was identified in the reporting period.

Complaint Log

ix. No complaints were received in the reporting period.

Notifications of any Summons and Successful Prosecutions

x. No notifications of summons and prosecutions were received in the reporting period.

Reporting Change
