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

4. to identify any negative impacts on sites of cultural heritage and to propose measures to mitigate these impacts;

5. to identify any potential landscape and visual impacts and to propose measures to mitigate these impacts;

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

7. 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 projects in relation to the sensitive receivers and potential affected uses;

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

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

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

11. 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.

For any additional and potential cumulative impacts identified by the review, the procedures listed below shall be followed:

1. Determination of Assessment Area

   The area for the noise impact assessment shall include all areas within 300m from the project boundaries. 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 projects boundaries, 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 projects, 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

Confirmation of the validity of the inventory shall be obtained from the relevant government departments/authorities.

5. Construction Noise Assessment
   1. The Applicant shall carry out assessment of noise impact from construction (excluding percussive piling) of the projects 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.

If the mitigated noise levels still exceed the relevant criteria, the duration of the noise exceedance shall be given.

6. Operational Noise Assessment
   1. The Applicant shall assess the impacts during the operational phase of the proposed railway and the associated facilities, involving worst case scenario, normal, abnormal, transient and emergency operations, with respect to the acceptable levels contained in Table 1A in Annex 5 in the TM.

   3. The Applicant shall make recommendations for noise amelioration for all existing or planned NSRs, which would be subject to predicted cumulative noise level in excess of the relevant planning criteria and statutory limits in the appropriate design year. A manual detailing the schedule of maintaining/capping the wheel/rail noise to suit the design specification shall be provided.

   4. For fixed noise sources (ventilating systems and fixed plants at stations and termini), the Applicant shall calculate the expected noise using standard acoustic principles. Calculations for the expected noise shall be based on assumed plant inventories and utilisation schedule for the worst case scenario. The Applicant shall calculate the noise levels taking into account of correction of tonality, impulsiveness and intermittency in accordance with the Technical Memorandum for the Assessment of Noise from Places other than Domestic Premises, Public Places or Construction Sites. The Applicant shall present the existing and future noise levels in Leq (30 min) at the NSRs on tables and plans of suitable scale. Quantitative assessment at the NSRs for proposed fixed noise source(s) shall be carried out and compared against the criteria set out in Table 1A of Annex 5 of the TM.

3.8.1 Baseline Study

A baseline study shall be conducted in accordance with the requirements set out in Annex A.

3.8.2 Impact Assessment

1. Cultural heritage impact assessment must be undertaken to identify the impacts of the sites of cultural heritage which will be affected by the proposed development subject to the result of desktop research and field evaluation. The prediction of impact and an evaluation of their significance must be undertaken by an expert in cultural heritage. During the assessment, both the direct impacts such as loss or damage of important features as well as indirect impacts such as change of water table levels which may affect the preservation of the archaeological and built heritage in situ should be stated. A detailed description and plans should be provided to elaborate to what extent the site of cultural heritage will be affected.

3.8.3 Mitigation Measures

1. It is always a good practice to recognise the site or monument early in the planning stage and site selection process, and to avoid it, i.e. preserve it in – situ, or leaving a buffer zone around the site. Built heritage, sites and landscapes are to be in favour of preservation unless it can be shown that there is a need for a particular development, which is of paramount importance and outweighs the significance of the heritage feature.

2. If avoidance of the cultural heritage is not possible, amelioration can be achieved by reduction of the potential impacts and the preservation of heritage features, such as physical relocating it. Measures like amendments of the sitting, screening and revision of the detailed design of the development are required to lessen its degree of exposure if it causes visual intrusion to the cultural heritage and affecting its character.

3. All the assessment should be conducted by an expert in cultural heritage.

4. Besides referring to paragraph 4.3.1(d), items 2.10 to 2.14 of Annex 19 and other relevant parts of the TM, proposals for mitigation measures should be accompanied with a master layout plan together with all detailed treatment, elevations, and landscape plan. A rescue programme, when required, shall be proposed which may involve preservation of the historical building or structure together with the relics inside, and its historic environment through relocation, detailed cartographic and photographic survey or preservation of an archaeological site "by record", i.e. through excavation to extract the maximum data as the very last resort.

5. The programme for implementation of agreed mitigation measures should be able to be implemented, and clearly stated in the EIA report, as required in Annex 20 of the TM. In particular, item 6.7 of Annex 20 requires the Applicant to define and list out clearly the proposed mitigation measures to be implemented, by whom, when, where, to what requirements and the various implementation responsibilities. A comprehensive plan and programme for the protection and conservation of the partially preserved Site of Cultural Heritage, if any, during the planning and design stage of the proposed project must be detailed.
