Environmental Impact Assessment Study Brief No. ESB-035/1999

Project Title : Dredging Works for Cruiser Operation in North Point
Name of Applicant : Super Winner Development Limited

1. BACKGROUND

1.1 An application (No. ESB-035/1999) for an Environmental Impact Assessment (EIA) study brief under section 5(1) of the Environmental Impact Assessment Ordinance (EIAO) was submitted by the Applicant on 16 June 1999 with a project profile (No. PP-051/1999) .

1.2 The Applicant proposes to carry out dredging works in order to allow cruisers with a maximum length of approximately 280m access to a proposed cruise pier in North Point. The proposed dredging area is located in Victoria Harbour off North Point as shown in Figure 1 of the Project Profile (No. PP-051/1999). The "designated project" is on the proposed dredging works which will involve removal of more than 500,000m3 of material as well as less than 100m from a seawater intake point. As described in the Project Profile, the proposed pier does not constitute a "designated project" as dredging is not required during the construction and the area-coverage is less than 1 ha. Therefore the EIA study brief will not cover the proposed pier.

1.3 Pursuant to section 5(7)(a) of the EIAO, the Director of Environmental Protection (the Director) issues this EIA study brief to the Applicant to carry out an EIA study.

1.4 The purpose of this EIA study is to provide information on the nature and extent of environmental impacts arising from the construction and operation of the proposed designated project and related activities taking place concurrently. This information will contribute to decisions by the Director on :

  1. the overall acceptability of any adverse environmental consequences that are likely to arise as a result of the proposed project;

  2. the conditions and requirements for the detailed design, construction and operation of the proposed project to mitigate against adverse environmental consequences wherever practicable; and

  3. the acceptability of residual impacts after the proposed mitigation measures are implemented.

2. OBJECTIVES OF THE EIA STUDY

2.1 The objectives of the EIA study are as follows:

  1. to describe the proposed project and associated works together with the requirements for carrying out the proposed project;

  2. to identify and describe the elements of the community and environment likely to be affected by the proposed project and/or likely to cause adverse impacts to the proposed project, including both the natural and man-made environment;

  3. to identify and quantify emission sources and determine the significance of impacts on sensitive receivers and potential affected uses;

  4. to propose the provision of infrastructure or mitigation measures so as to minimize pollution, environmental disturbance and nuisance during construction and operation of the project;

  5. to identify, predict and evaluate the residual (i.e. after practicable mitigation) environmental impacts and the cumulative effects expected to arise during the construction and operation phases of the project in relation to the sensitive receivers and potential affected uses;

  6. to identify, assesses and specify methods, measures and standards, to be included in the detailed design, construction and operation of the project which are necessary to mitigate these environmental impacts and reducing them to acceptable levels;

  7. to investigate the extent of side-effects of proposed mitigation measures that may lead to other forms of impacts;

  8. to identify constraints associated with the mitigation measures recommended in the EIA study;

  9. to design and specify the environmental monitoring and audit requirements, if required, to ensure the implementation and the effectiveness of the environmental protection and pollution control measures adopted.

3. DETAILED REQUIREMENTS OF THE EIA STUDY

3.1 The Purpose

The purpose of this study brief is to scope the key issues of the EIA study. The Applicant has to demonstrate in the EIA report that the criteria in the relevant sections of the Technical Memorandum on the Environmental Impact Assessment Process of the Environmental Impact Assessment Ordinance (thereafter referred to as the TM), are fully complied with.

3.2 The Scope
The scope of this EIA study covers the proposed project mentioned in section 1.2 above.

3.3 Technical Requirements

The Applicant shall conduct the EIA study to address all environmental aspects of the activities as described in the scope as set out above. The EIA study shall include the following technical requirements on specific impacts:

3.3.1 Noise Impact

3.3.1.1 The Applicant shall follow the criteria and guidelines for evaluating and assessing noise impact as stated in Annexes 5 and 13 of the TM, respectively.

3.3.1.2 The noise impact assessment shall include the following :

  1. Determination of Assessment Area

    The area for the noise impact assessment shall include all areas within 300m from the project boundary. Subject to the agreement of the Director, the assessment area could be reduced accordingly if the first layer of noise sensitive receivers, closer than 300m from the project boundary, provides acoustic shielding to those receivers at further distance behind.

  2. Provision of Background Information and Existing Noise Levels

    The Applicant shall provide all background information relevant to the project, e.g. relevant previous or current studies. Unless involved in the planning standards, e.g. those for planning of fixed noise sources, no existing noise levels are particularly required.

  3. Identification of Noise Sensitive Receivers

    1. The Applicant shall refer to Annex 13 of the TM when identifying the noise sensitive receivers (NSRs). The NSRs shall include all existing NSRs and all planned/committed noise sensitive developments and uses earmarked on the relevant Outline Zoning Plans, Outline Development Plans and Layout Plans.

    2. The Applicant shall select assessment points to represent all identified NSRs for carrying out quantitative noise assessment described below. The assessment points shall be agreed with the Director prior to the quantitative noise assessment. A map showing the location and description such as name of building, use, and floors of each and every selected assessment point shall be given.

  4. Provision of an Emission Inventory of the Noise Sources

    The Applicant shall provide an inventory of all noise sources from the proposed dredging works. Confirmation of the validity of the inventory shall be obtained from the relevant government departments/authorities.

  5. Noise Assessment

    1. The Applicant shall carry out assessment of noise impact from the proposed dredging works during day time, i.e. 7 a.m. to 7 p.m., on weekdays other than general holidays in accordance with the methodology stipulated in paragraphs 5.3. and 5.4 of Annex 13 of the TM. The criteria in Table 1B of Annex 5 of the TM shall be adopted in the assessment.

    2. If the unmitigated construction noise levels are found exceeding the relevant criteria, the Applicant shall propose practicable direct mitigation measures (including movable barriers, enclosures, quieter alternative methods, re-scheduling and restricting hours of operation of noisy task) to minimize the impact. If the mitigated noise levels still exceed the relevant criteria, the duration of the noise exceedance shall be given.

    3. In case the applicant would like to evaluate whether the proposed dredging works in restricted hours as defined under the Noise Control Ordinance (NCO) are feasible or not in the context of programming works schedule, reference should be made to the relevant technical memoranda issued under the NCO. Regardless of the results of construction noise impact assessment for restricted hours, the Noise Control Authority will consider a well-justified Construction Noise Permit (CNP) application, once filed, based on the NCO, the relevant technical memoranda issued under the NCO, and the contemporary conditions/situations of adjoining land uses and any previous complaints against construction activities at the site before making his decision in granting a CNP. This aspect should be explicitly stated in the noise chapter and the conclusions and recommendations chapter in the EIA report.

  7. prediction and quantification, by mathematical modelling or other technique subject to approval of the Director, of impacts on the water system(s) and the sensitive receivers due to those alterations and changes identified in (v) above and the pollution sources identified in (vi) above. Possible impacts include changes in hydrology, flow regime, sediment erosion or deposition, water and sediment quality and the effects on the aquatic organism due to such changes. The prediction shall include possible different construction stages or sequences, and different operation stages;
