Environmental Impact Assessment Study Brief No. ESB-054/2000
Project Title: Construction of Lung Kwu Chau Jetty
Name of Applicant : Civil Engineering Department, the Government of the HKSAR?span class="x-font-size-2">
1.1 An application (No.ESB-054/2000) for an Environmental Impact Assessment (EIA) study brief under section 5(1) of the Environmental Impact Assessment Ordinance (EIAO) was submitted by the captioned Applicant on 23 May 2000 with a project profile (No.PP-090/2000).
1.2 A Doppler VHF Omni-directional Range/Distance Measuring Equipment (DVOR/DME) Station is being operated at Lung Kwu Chau to provide bearing and distance information to the approaching aircraft to and from the Chek Lap Kok Airport. Currently, the transportation of equipment for servicing the DVOR/DME is carried out by helicopters as the existing jetty at Lung Kwu Chau is considered too small for Civil Aviation Department's vessels to carry out the transportation work by sea. However, helicopter works are prohibited during nighttime and adverse weather conditions hence emergency repairing work is not possible under these conditions.
1.3 The applicant proposes to reconstruct an existing jetty at Lung Kwu Chau to facilitate transportation of servicing equipment for the DVOR/DME by sea. The proposed site is located at the eastern coast of Lung Kwu Chau as shown in the attached Figure 1. The proposed project is classified as a designated project under Item Q.1 of Part I of Schedule 2 of the EIAO as the proposed work site is located wholly within the Sha Chau and Lung Kwu Chau Marine Park and the adjacent Site of Special Scientific Interest (SSSI) at Lung Kwu Chau, Tree Island and Sha Chau, location of which are shown in the attached Figure 2. The proposed scope of work are as follows:-
(i) construction of a precast concrete blockwork jetty of 10m by 20m with a single berth;
(ii) construction of a concrete catwalk of approximately 62m long;
(iii) dredging of an approach channel of about 8500 m2 in size to a level of -2.5mCD in front of the berth;
(iv) installation of miscellaneous facilities on the jetty, including lighting, navigation light, fendering, handrails, tide gauge, etc., and;
(v) demolition of the existing jetty upon completion of the proposed jetty.
1.4 Pursuant to section 5(7)(a) of the EIAO, the Director of Environmental Protection (the Director) issues this Environmental Impact Assessment (EIA) study brief to the Applicant to carry out an EIA study.
1.5 The purpose of this EIA study is to provide information on the nature and extent of environmental impact arising from the construction and operation of the proposed designated project and related activities taking place concurrently.

(ii) the conditions and requirements for the detailed design, construction and operation of the proposed project to mitigate against adverse environmental consequences wherever practicable; and
(iii) the acceptability of residual impacts after the proposed mitigation measures are implemented.
2. OBJECTIVES OF THE EIA STUDY

(A) Proposed Aviation Fuel Receiving Facility at Sha Chau: EIA Volume 1 & 2 (EIAO Register ref. EIA-053/BC)
(B) EIA Study for Disposal of Contaminated Mud in the East Sha Chau Marine Borrow Pit (EIAO Register ref. EIA-107/BC)
(C) Jefferson T (1998) Population Biology of the Indo-Pacific Hump-backed Dolphin (Sousa chinensis Osbeck, 1765) in Hong Kong Waters: Final Report, submitted to Agriculture and Fisheries Dept., Hong Kong SAR Government 15 April 1998
(D) Study on Tonggu Waterway: Final Report July 1999 Scott Wilson (Hong Kong) Ltd. to the Civil Engineering Dept., Hong Kong SAR Government
Guidelines for Marine Archaeological Investigation (MAI)
The standard practice for MAI should consist of four separate tasks, i.e., (1) Baseline Review, (2) Geophysical Survey, (3) Establishing Archaeological Potential and (4) Remote Operated Vehicle (ROV)/Visual Diver Survey/Watching Brief.
1. Baseline Review
1.1 A baseline review should be conducted to collate the existing information in order to identify the potential for archaeological resources and, if identified, their likely character, extent, quality and value.
1.2 The baseline review will focus on known sources of archive data. It will include:-
(a) Geotechnical Engineering Office (GEO) - the Department holds extensive seabed survey data collected from previous geological research. (b) Marine Department, Hydrographic Office - the Department holds a substantial archive of hydrographic data and charts. (c) The Royal Naval Hydrographic Department in the UK - the Department maintains an archive of all survey data collected by naval hydrographers.
1.3 The above data sources will provide historical records and more detailed geological analysis of submarine features which may have been subsequently masked by more recent sediment deposits and accumulated debris.
2. Geophysical Survey
2.1 Extensive geophysical survey of the study area should deploy high resolution boomer, side scan sonar and an echo sounder. The data received from the survey would be analyzed in detail to provide:-
(a) Exact definition of the areas of greatest archaeological potential.
(b) Assessment of the depth and nature of the seabed sediments to define which areas consist of suitable material to bury and preserve archaeological material.
(c) Detailed examination of the boomer and side scan sonar records to map anomalies on the seabed which may be archaeological material.
3. Establishing Archaeological Potential
3.1 The data examined during Tasks 1 and 2 will be analyzed to provide an indication of the likely character and extent of archaeological resources with the study area. This would facilitate formulation of a strategy for investigation.
3.2 The results would be presented as a written report and charts. If there is no indication of archaeological material there would be no need for further work, subject to the agreement of the Antiquities and Monuments Office (AMO).
4. Remote Operated Vehicle (ROV)/Visual Diver Survey/Watching Brief
4.1 Subject to the outcome of Tasks 1, 2 and 3, accepted marine archaeological practice would be to plan a field evaluation programme to acquire more detailed data on areas identified as having archaeological potential. The areas of archaeological interest can be inspected by ROV or divers. ROV or a team of divers with both still and video cameras would be used to record all seabed features of archaeological interest.
4.2 Owing to the heavy marine traffic in Hong Kong, the ROV/visual diver survey may not be feasible to achieve the target. If that is the case, an archaeological watching brief is the most appropriate way to monitor the dredging operations in areas of identified high potential to obtain physical archaeological information.
4.3 A sampling strategy for an archaeological watching brief would be prepared based on the results of Tasks 1, 2 and 3 to focus the works on areas of greatest archaeological potential. Careful monitoring of the dredging operations would enable immediate identification and salvage of archaeological material. If archaeological material is found, the AMO should be contacted immediately to seek guidance on its significance and appropriate mitigation measures would be prepared.
5.1 If Task 4 is undertaken, the results would be presented in a written report with charts. ?span>
