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 31 October 2021 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:

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 are presented in Annex D. No non-compliance with environmental statutory requirements was identified.
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, marine water quality monitoring, marine mammal monitoring (i.e. vessel-based line transect survey and passive acoustic monitoring) and marine mammal exclusion zone monitoring were conducted, and the findings are presented below.
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, four (4) sessions of environmental site inspection were carried out on 6, 12, 21 and 27 October 2021. The Independent Environmental Checker (IEC) attended the environmental site inspections as the IEC audits on 6, 21 and 27 October 2021 during the reporting period. 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.

In accordance with the Updated EM&A Manual, marine water quality monitoring shall be undertaken at the monitoring stations as shown in Figure 2.1 and Table 2.5 three times a week at both mid-ebb and mid-flood tides during periods when there are dredging / jetting operations during construction phase of BPPS Pipeline or LPS Pipeline. The interval between two sets of monitoring would not be less than 36 hours. Two replicates of in-situ measurements and samples were 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 whereas the level of suspended solids (SS) were determined by a HOKLAS accredited laboratory. The detailed methodology is presented in the Updated EM&A Manual.

The monitoring results and graphical presentations are provided in Annex G. No Action and Limit Level exceedances were recorded for marine water quality monitoring in the reporting period.
In accordance with the Updated EM&A Manual, vessel-based marine mammal survey by means of systematic line-transect boat survey was undertaken to examine the distribution and encounter rate of Finless Porpoise (FP) in southern Lantau where a majority of Project construction works would take place. Survey transects covered three survey areas for line-transect boat surveys, namely Southwest Lantau (SWL), Southeast Lantau (SEL) and Lamma (LM) are presented in Figure 2.2. The methodology of the survey is consistent and compatible with that adopted in the EIA baseline surveys as well as the long-term marine mammal monitoring programme conducted by AFCD since 1995 to allow potential comparisons and pooling data for analysis. Vessel-based line transect marine mammal surveys are conducted during construction of the LNG Terminal. Each transect line is surveyed twice per month. The detailed methodology is presented in the Updated EM&A Manual.
In accordance with the Updated EM&A Manual, underwater PAM survey using C-POD (Cetacean-Porpoise Detector) was conducted at five locations as presented in Figure 2.3. C-PODs are left in place during construction of the LNG Terminal. Such duration should allow for a robust record of marine mammal usage of the area to be obtained and allow for the inter-seasonal differences already known for finless porpoises. The C-PODs have to be serviced every two to four months, subject to review on an as-needed basis, to download accumulated data and replace batteries.
The Action and Limit Levels for marine mammal monitoring are established using encounter rate calculated from the six-month baseline vessel-based line transect surveys from the three survey areas as a whole in accordance with the Updated EM&A Manual. The combined baseline encounter rate will be used to compare with the encounter rate obtained during construction phase monitoring calculated from last three month’s monitoring data (i.e. running quarterly value). This approach would allow natural seasonal fluctuations in FP encounter rate to be accounted for, and allow data to be reviewed every month such as appropriate remedial actions could be taken timely if the threshold values are triggered. The Action and Limit Levels are provided in Table 2.9.

The Event and Action Plan for marine mammal monitoring is provide in Annex K.
The schedule for marine mammal monitoring for the reporting period is provided in Annex M.
Vessel-based line transect surveys were conducted on 5, 11, 15, 22, 26 and 28 October 2021. A total of 436.10 km of survey effort was collected from the surveys, which included 142.06 km in SWL, 135.80 km in SEL and 158.24 km in LM. The total survey effort conducted on primary and secondary lines were 361.44 km and 74.66 km respectively. 21.97% of the total survey effort was conducted in condition of Beaufort Sea State 2 or below with good visibility, and such data can be utilised for the encounter rate analysis.
Two FPs were sighted during on-effort search. One FP was sighted in the vicinity of Shek Kwu Chau and the other one was sighted at the southernmost line in LM (see Figure 2.4). Of these FP sightings, none were sighted at Beaufort Sea State 2 or below and they were not utilised for encounter rate analysis.
The monthly STG and ANI for the combined survey areas from SWL, SEL and LM during the reporting period are summarised in Table 2.10.

Notes: Only data collected at Beaufort Sea State 2 or below were included for encounter rate analysis. Running STG and Running ANI were calculated by combining three consecutive survey months data (i.e. running STG/ANI for Oct 2021 were calculated by combining the data in Aug – Oct 2021). |
|||||||
The running quarterly values of encounter rate in terms of STG and ANI were 1.12 and 3.97, respectively. Therefore, there were no breaches of Action and Limit Levels for marine mammal monitoring in the reporting period.
Five C-POD units have been deployed at the five locations since the commencement of construction for FEP-01/558/2018/A on 27 November 2020. These units are serviced every two to four months, subject to review on an as-needed basis, to download accumulated data and replace batteries. The latest round of C-POD servicing was conducted in early July 2021.
According to Condition 3.7 of FEP-01/558/2018/A, Condition 3.7 of FEP-02/558/2018/A, Condition 3.8 of FEP-03/558/2018/B, Section 9.11.3 of the approved EIA Report and Section 7 of the Updated EM&A Manual, marine mammal exclusion zone monitoring with 250m radius and that with 500m radius are required during the course of dredging / jetting operations for construction of BPPS Pipeline or LPS Pipeline, and percussive piling works for construction of the Jetty, respectively. Marine mammal exclusion zone requirements for marine dredging or jetting operations for construction of BPPS Pipeline or LPS Pipeline, and percussive piling works for construction of the Jetty are presented in Table 2.12.
Table 2.12 Marine Mammal Exclusion Zone Requirements
|
Activity |
Exclusion Zone |
Requirement |
|
Marine dredging or jetting operations |
250m |
Before pipeline dredging or jetting commence, the exclusion zone must have been continuously clear of marine mammals for 30 minutes. During pipeline dredging / jetting, if marine mammals are spotted within the exclusion zone, pipeline dredging/ jetting works will cease and will not resume until the observer confirms that the zone has been continuously clear of marine mammals for a period of 30 minutes. |
|
Percussive piling works for construction of the Jetty |
500m |
Before percussive piling commences, the exclusion zone must have been continuously clear of marine mammals for 30 minutes. During percussive piling, if marine mammals are spotted within the exclusion zone, percussive piling works will cease and will not resume until the observer confirms that the zone has been continuously clear of marine mammals for a period of 30 minutes. |
Marine mammal exclusion zone monitoring with 250m radius was conducted between 1 and 2 October 2021 for marine jetting operation undertaken at South of Shek Kwu Chau to West Lamma Channel (KP5.0 – 14.5) for the LPS Pipeline. Marine mammal exclusion zone monitoring with 250m radius was conducted on 1 to 4 and 18 to 31 October 2021 for marine jetting operation undertaken at West of Tai O to West of HKIA (KP21.3 – 31.5) for the BPPS Pipeline. Marine mammal exclusion zone monitoring with 500m radius was conducted on 2, 4 to 7, 15, 19 to 23 and 27 to 30 October 2021 for percussive piling works undertaken for construction of the Jetty. No sightings of marine mammals were observed during marine mammal exclusion zone monitoring in the reporting period.
The operating speeds and marine travel routes of working vessels for construction of the Project within the reporting period were checked and reviewed. 13 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 except a working vessel (Zhong You Hai 281) which was operated at a speed higher than 10 knots within the area frequented by marine mammals south to Southwest Lantau Marine Park on 30 October 2021. However, this incident was caused by current influence upon investigation. 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 O.
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 and the proposed South Lantau Marine Park (SLMP) in pursuant to Condition 3.1 of FEP-01/558/2018/A for anchoring activities for piling operation and jacket installation 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 2.13.

· For anchor relocation and anchorage monitoring for main construction vessel working on pipelaying works for BPPS Pipeline, the AHT will transit through and stop over Sha Chau and Lung Kwu Chau Marine Park (SCLKCMP) with a frequency of 5 times per day for a duration of 30 days,
· For pipeline transportation for pipelaying works for BPPS Pipeline, flat-top barge will transit through and stop over SCLKCMP with a frequency of 1 time per day for a duration of 30 days,
Notes:
(1) Strong wind signal No. 3 and gale or storm signal No. 8 were in force from 4:40 AM on 8 October 2021 to 6:40 AM on 9 October 2021 and from 6:40 AM on 9 October 2021 to 4:40 AM on 10 October 2021, respectively.
(2) Working vessels unavoidably entered into and transited through SCLKCMP adjacent to Lung Kwu Chau with respect to the fact that relatively shallow water depth (< 5m) in the western waters of SCLKCMP compared to the drafts of the working vessels (~3.5-4m for Zhong You Hai 101; ~ 4.5m for Zhong You Hai 281) imposes the risk of ship grounding, taking concerns of marine traffic and safety into consideration.
(3) Current influence on working vessels during anchor recovery.
