To support the increased use of natural gas in Hong Kong from 2020 onwards, Castle Peak Power Company Limited (CAPCO) and The Hongkong Electric Co., Ltd. (HK Electric) have identified that the development of an offshore liquefied natural gas (LNG) receiving terminal in Hong Kong using Floating Storage and Regasification Unit (FSRU) technology (‘the Project’) presents a viable additional gas supply option that will provide energy security through access to competitive gas supplies from world markets. The Project will involve the construction and operation of an offshore LNG import facility to be located in the southern waters of Hong Kong, a double berth jetty, and subsea pipelines that connect to the gas receiving stations (GRS) at the Black Point Power Station (BPPS) and the Lamma Power Station (LPS). To demarcate the works between different parties, the following Further Environmental Permits (FEPs) were issued for the Project:
§ the double berth jetty at LNG Terminal under the Hong Kong LNG Terminal Limited (HKLTL), joint venture between CAPCO and HK Electric (FEP-01/558/2018/A) – construction commenced on 27 November 2020;
§ the subsea gas pipeline for the BPPS and the associated GRS in the BPPS under CAPCO (FEP-03/558/2018/B) – construction commenced on 23 September 2020; and
§ the subsea gas pipeline for the LPS and the associated GRS in the LPS under HK Electric (FEP-02/558/2018/A) – construction commenced on 13 December 2020.

The environmental licenses and permits, including further environmental permits, registration as chemical waste producer, construction noise permits, wastewater discharge license, marine dumping permits, etc., which were valid in the reporting period. No non-compliance with environmental statutory requirements, including FEP conditions (status of submission) under the EIA Ordinance was identified. The status of statutory environmental requirements is presented in Annex D.
The potential environmental impacts arising from the major construction activities undertaken in the reporting period provided in Table 1.3 were mainly associated with dust emission from construction activities, waste management, and disturbance to marine mammals due to marine-based works. There were no Project-related Action and Limit Level exceedances and no non-compliance of environmental statutory requirements identified for the environmental monitoring and auditing works conducted in the reporting period, including regular site inspections of construction works conducted by the ET, audit of implementation of Waste Management Plan, review of the acceptability of operating speeds and marine travel routes of working vessels, and checking of compliance with the approval conditions given by EPD for allowing the entry of working vessels within marine parks in pursuant to Condition 3.1 of FEP-01/558/2018/A, Condition 3.4 of FEP-02/558/2018/A and Condition 3.4 of FEP-03/558/2018/B, as appropriate. The recommended environmental mitigation measures were properly implemented in the reporting period. Excessive variation between the EIA study predictions and the EM&A monitoring results was not found and therefore no investigation and follow-up procedures were considered necessary.
The
environmental mitigation implementation schedule (EMIS) is presented in Annex C.
The EM&A programme for the Project required environmental monitoring for marine water quality and marine mammals as well as environmental site inspections for air quality, construction noise, water quality, waste management, marine ecology, landscape and visual, and hazard to life impacts. As presented in Section 1.6, environmental site inspections, audit on waste management practice and marine water quality monitoring for hydrotesting for the LPS Pipeline and BPPS Pipeline were conducted during the reporting period, and the findings are presented below. In addition, as marine-based construction activities were completed in October 2022, the post-construction monitoring for marine water quality was conducted between 7 November and 2 December 2022 in accordance with the Updated EM&A Manual and the results are reported in the post-construction water quality monitoring report. The post-construction monitoring for marine mammals has been conducted since November 2022 in accordance with the Updated EM&A Manual and the results will be reported in the post-construction marine mammal monitoring reports upon completion of the monitoring.
Regular environmental site inspections were 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 inspections were carried out on 5, 12, 26 October, 9 November and 20 December 2022. The Independent Environmental Checker (IEC) attended the environmental site inspections as the IEC audits on 5, 26 October, 9 November and 20 December 2022 during the reporting period. The environmental protection and pollution control mitigation measures were implemented properly. There were no key observations from site inspections and thus no Contractor’s follow-up actions were necessary for the reporting period. The environmental mitigation implementation schedule (EMIS) is presented in Annex C.
Waste management audits were performed with reference to the Waste Management Checklists for the corresponding Waste Management Plans detailed in Annex E of the associated Monthly EM&A Reports during the regular environmental site inspections carried out in the reporting period. No non-compliance for Contractor’s waste management practices was identified during the audits.
The quantities of different types of waste and marine sediment generated for the three FEPs are summarised in Tables 2.1, 2.2 and 2.3 with reference to the waste flow tables prepared by the Contractor. General refuse was generated under FEP-01/558/2018/A and FEP-03/558/2018/B, and inert C&D materials (public fill) were also generated under FEP-03/558/2018/B in the reporting period. Detailed waste flow tables can be referred to Annex F of the associated Monthly EM&A Reports for the reporting period.

In accordance with the Updated EM&A Manual, water quality monitoring for hydrotesting for the subsea gas pipelines would be conducted before, during and after discharge of hydrotest water for the two subsea gas pipelines at the nearest sensitive receiver (i.e. IM6) and nearby control station(s) (i.e. E2 and / or F3 depending on the tidal state) as shown in Figure 2.1 and Table 2.4. As agreed with IEC, one water quality monitoring event would be conducted within one week prior to hydrotesting discharge for each pipeline the monitoring, water quality monitoring would be conducted at a frequency of three times per week capturing the timing of hydrotesting discharge as far as practicable, and only one water quality monitoring event would be conducted after one week of completion of hydrotesting discharge for both pipelines. For a single water quality monitoring event, two rounds of measurement would be conducted during flood tide and two rounds of measurement would be conducted during ebb tide and each round of monitoring for each tide would be separated by at least an hour. Two replicates of in-situ measurements and samples would be collected at each monitored water depth of each monitoring stations. Levels of dissolved oxygen (DO), pH value, salinity, temperature and turbidity would be measured in-situ.

The Event and Action Plan for marine water quality monitoring can be referred to the Updated EM&A Manual.
A total of 8 monitoring events for marine water quality monitoring for hydrotesting for the BPPS and LPS Pipelines during discharge were conducted in the reporting period. One water quality monitoring event was conducted on 29 October 2022 after one week of completion of hydrotesting discharge for both pipelines. The monitoring results were presented in the respective Monthly EM&A Reports. There were no Project-related Action and Limit Level exceedances for marine water quality monitoring for hydrotesting for the BPPS and LPS Pipelines in the reporting period. The results of water quality monitoring after completion of hydrotesting discharge for both pipelines also indicated that there was no unacceptable change on the levels of DO and thus the hydrotest discharges for both pipelines did not result in unacceptable change in water quality.
The operating speeds and marine travel routes of working vessels for construction of the Project within the reporting period were checked and reviewed for the reporting period.
