2. EM&A Results

The EM&A programme for the Project required environmental monitoring for marine water quality and marine mammals as well as environmental site inspection for air quality, construction noise, water quality, waste management, marine ecology, landscape and visual, and hazard to life impacts. As marine-based construction activities have been completed, the post-construction monitoring for marine water quality was completed on 2 December 2022 and the results were reported in the post-construction water quality monitoring report. The post-construction monitoring for marine mammals was conducted in this reporting period and the results will be reported in the post-construction marine mammal monitoring reports upon completion of the monitoring. As presented in Section 1.5, environmental site inspection and audit on waste management practice were conducted, and the findings are presented below.

2.1 Environmental Site Inspection

Regular environmental site inspection was carried out with the Contractor and Project Proponents to confirm the implementation of appropriate environmental protection and pollution control mitigation measures for air quality, construction noise, water quality, waste management, marine ecology, landscape and visual, and hazard to life impacts under the Project. In the reporting period, environmental site inspection was carried out for the review on the mitigation measures implemented for the double berth jetty under FEP-01/558/2018/A on 23 February 2023. No construction works were conducted for FEP-02/558/2018/A and FEP-03/558/2018/B during the reporting period and thus environmental site inspection was not undertaken for FEP-02/558/2018/A and FEP-03/558/2018/B in the reporting period. The Independent Environmental Checker (IEC) attended the environmental site inspection as the IEC audit on 23 February 2023 during the reporting period. The environmental protection and pollution control mitigation measures were implemented properly. The key observation from site inspection and Contractor’s follow-up action are summarised in Table 2.1. The environmental mitigation implementation schedule (EMIS) is presented in Annex C.

Table 2.1 Key Observations from Site Inspections and Contractor’s Follow-up Actions
