Executive Summary
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.
This is the Monthly EM&A Report presenting the EM&A works carried out during the period from 1 to 30 September 2022 for the Project in accordance with the Updated EM&A Manual. A summary of monitoring and audit activities conducted in the reporting period is listed below:

Environmental auditing works, including regular site inspections of construction works conducted by the Environmental Team (ET), audit of implementation of Waste Management Plan, and review of the acceptability of operating speeds and marine travel routes of working vessels, checking of compliance with the approval conditions given by the Director of Environmental Protection for 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, were conducted in the reporting period, as appropriate. No non-compliance of environmental statutory requirements was identified.
Breaches of Action and Limit Levels
There were no Project-related Action and Limit Level exceedances for marine water quality monitoring for hydrotesting for the BPPS Pipeline and LPS Pipeline in the reporting period.
Since construction phase marine mammal monitoring was completed in November 2021, there were no breaches of Action and Limit Levels for marine mammal monitoring in the reporting period.
Environmental Complaints, Notification of Summons and Successful Prosecution
There was one environmental complaint received on the alleged dumping of waste into sea between Shek Kwu Chau and Tai A Chau in the reporting period. Upon investigation, no construction & demolition (C&D) waste was generated from the Project in the past two weeks upon receipt of complaint (i.e. between 7 and 21 September 2022). There is no evidence showing any unacceptable waste management practice for the Project. Environmental protection / mitigation measures were observed to be implemented properly in accordance with the Implementation Schedule as well as the environmental requirements under the Further Environmental Permits and the approved EIA report (Register No.: AEIAR-218/2018). The complaint is thus considered invalid.
There were no notification of summons and successful prosecutions recorded in the reporting period.
Reporting Changes
There were no reporting changes in the reporting period.

Introduction
1.1
Background
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).
The Environmental Impact Assessment (EIA) Report for the Project was submitted to the Environmental Protection Department (EPD) of the HKSAR Government in May 2018. The EIA Report (EIAO Register No. AEIAR-218/2018) was approved by EPD and the associated Environmental Permit (EP) (EP-558/2018) was issued in October 2018.
An application for Further Environmental Permits (FEP) were made on 24 December 2019 to demarcate the works between the different parties. The following FEPs were issued on 17 January 2020 and the EP under EP-558/2018 was surrendered on 5 March 2020.
§ 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) ([1]) – 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) ([2]) – 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) ([3]) – construction commenced on 13 December 2020.
The location of these components is shown in Figures 1.1, 1.2 and 1.3.

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 inspections for air quality, construction noise, water quality, waste management, marine ecology, landscape and visual, and hazard to life impacts. As presented in Section 1.5, environmental site inspections, audit on waste management practice and marine water quality monitoring for hydrotesting for the LPS Pipeline and BPPS Pipeline were conducted, and the findings are presented below.
2.1
Environmental
Site Inspection
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 for the review on the mitigation measures implemented on 1, 7, 14 and 29 September 2022 ([4]). The Independent Environmental Checker (IEC) attended the environmental site inspections as the IEC audits on 7 and 29 September 2022 during the reporting period. The environmental protection and pollution control mitigation measures were implemented properly. The key observations from site inspections and Contractor’s follow-up actions are summarised in Table 2.1. The environmental mitigation implementation schedule (EMIS) is presented in Annex C.

Marine Water Quality Monitoring for Hydrotesting for
the Subsea Gas Pipelines
2.3.1
Monitoring
Requirements
In accordance with the Updated EM&A Manual, water quality monitoring for hydrotesting for the subsea gas pipelines will 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 2.5. As agreed with IEC, one water quality monitoring event will be conducted within one week prior to hydrotesting discharge for each pipeline the monitoring, water quality monitoring will 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 will be conducted after one week of completion of hydrotesting discharge for both pipeline. For a single water quality monitoring event, two rounds of measurement will be conducted during flood tide and two rounds of measurement will be conducted during ebb tide and each round of monitoring for each tide will 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 were measured in-situ.

Action
and Limit Levels for Marine Water Quality Monitoring for Hydrotesting for the Subsea Gas Pipelines
As predicted in the water quality modelling, there would be depletion of DO due to hydrotest discharge and thus the Action and Limit Levels of DO were established. The Action and Limit Levels for marine water quality monitoring for hydrotesting for the subsea gas pipelines were established based on the baseline marine water quality monitoring data. In addition, the representativeness of the data was reviewed with reference to the water quality monitoring data obtained within one week before hydrotest discharge. The water quality monitoring for hydrotesting of BPPS Pipeline before discharge was conducted on 10 September 2022 (raw data in Annex G) and the monitoring results showed that the levels of DO ranged from 6.34-7.76 mg/L (Surface and Middle) and 5.90-6.42 mg/L (Bottom) at the monitoring stations and were within the ranges of DO obtained from the baseline marine water quality monitoring before construction of the Project. It is thus considered that the baseline marine water quality monitoring data for Group 3 where Station IM6 is located are still valid and representative for establishing the Action and Limit Levels. The Action and Limit Levels of DO are presented in Table 2.6.

A total of 9 working vessels were used for construction of the BPPS Pipeline and the LPS Pipeline under FEP-03/558/2018/B and FEP-02/558/2018/A, respectively, and for construction of the Jetty under FEP-01/558/2018/A during the reporting period. All these working vessels were operated at a speed lower than 10 knots when moving within the areas frequented by marine mammals, including the waters near Sha Chau and Lung Kwu Chau Marine Park, the waters at the west of Lantau Island and the waters between Soko Islands and Shek Kwu Chau, and followed the relevant marine travel requirements stipulated in the FEPs. No non-compliance on the operating speeds and marine travel routes of working vessels was identified. Records of operating speeds and marine travel routes of working vessels for construction of the Project provided by the Contractor are presented in Annex M.
The compliance status on approval conditions given by the Director of Environmental Protection for the entry of working vessels (i.e. anchor handling tugs (AHTs)) within marine parks in pursuant to Condition 3.1 of FEP-01/558/2018/A for anchoring activities for construction of the Jetty, Condition 3.4 of FEP-02/558/2018/A and Condition 3.4 of FEP-03/558/2018/B for anchoring activities for pipelaying and/or post-trenching processes for construction of LPS and BPPS Pipelines, respectively, as appropriate within the reporting period was checked. No non-compliance on the approval conditions was identified. Records of entry events of working vessels within marine parks and the SLMP for construction of the Project provided by the Contractor were presented in Table 2.9.

Summary
of Exceedances of the Environmental Quality Performance Limit
There were no Project-related Action and Limit Level exceedances for marine water quality monitoring for hydrotesting for the BPPS Pipeline and LPS Pipeline in the reporting period.
Since construction phase marine mammal monitoring was completed in November 2021, there were no breaches of Action and Limit Levels for marine mammal monitoring in the reporting period.
Cumulative statistics on exceedance is provided in Annex J.
2.7
Summary
of Environmental Complaints, Notification of Summons and Successful
Prosecutions
There was one environmental complaint received on the alleged dumping of waste into sea between Shek Kwu Chau and Tai A Chau in the reporting period. Upon investigation, no construction & demolition (C&D) waste was generated from the Project in the past two weeks upon receipt of complaint (i.e. between 7 and 21 September 2022). There is no evidence showing any unacceptable waste management practice for the Project. Environmental protection / mitigation measures were observed to be implemented properly in accordance with the Implementation Schedule as well as the environmental requirements under the Further Environmental Permits and the approved EIA report (Register No.: AEIAR-218/2018). The complaint is thus considered invalid.
There were no notification of summons and successful prosecutions recorded in the reporting period.
Statistics on environmental complaints, notification of summons and successful prosecutions are summarised in Annex J.
