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 4th Quarterly EM&A Summary Report for the Contract which summaries findings of the EM&A programme during the reporting period from 1 January 2022 to 31 March 2022. As informed by the Contractor, major activities in the reporting period were 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 Environmental Quality Performance Limits (AL 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 and Limit Level exceedance was recorded for water quality in the reporting period.

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

vii. No Action / Limit Level exceedance for the ecological monitoring of birds during the reporting period.

viii. No corrective actions were required according to the Event and Action Plans for the Monitoring Parameters.

Land Contamination

ix. Regular site inspection was carried out to ensure the recommended mitigation measures are properly implemented. Site investigation (SI) work was completed by 6 January 2022 and the signed final Contamination Assessment Report (CAR) for Main Storeroom & Workshops was submitted to EPD on 1 November 2021. The signed final Contamination Assessment Report (CAR) for Mechanical Workshop was submitted to EPD on 23 November 2021. No contaminated soil and ground water was found within the Main Storeroom & Workshop and the Mechanical Workshop, and no remedial action is required for both locations. While the laboratory results of sampling works show that there is no contaminated soil or groundwater within the Waste Storage Area, the findings are summarized in the draft CAR for the area which is under review and will be submitted to EPD.

Complaint Log

x. No complaints were received in the reporting period.

Notifications of any Summons and Successful Prosecutions

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

Reporting Change

xii. There were no reporting changes during the reporting period.
