22.214.171.124 The noise impact assessment shall include the following:
(i) Determination of Assessment Area
The study area for the noise impact assessment shall generally include all areas within 300m from the Project shown in Annex A or other Project alignments as identified in the EIA. Subject to the agreement of the Director, the assessment area could be reduced accordingly if the first layer of noise sensitive receivers (NSRs), closer than 300m from the outer Project limit, provides acoustic shielding to those receivers at distances further away from the Project. Subject to the agreement of the Director, the assessment area shall be expanded to include NSRs at distances over 300m from the Project, which are affected by the construction and operation of the Project.
(ii) 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 required for determining the planning standards, e.g. those for planning of fixed noise sources (such as ventilation systems of traffic noise enclosures), no existing noise levels are particularly required.
(iii) Identification of Noise Sensitive Receivers
(a) The Applicant shall refer to Annex 13 of the TM when identifying the NSRs. The NSRs shall include all existing NSRs and all planned/ committed noise sensitive developments and uses, including but not limiting to residential developments at the Airport Express Kowloon Station, future developments at the Comprehensive Development Area next to Airport Express Kowloon station, Man Cheong Street residential area, residential developments along Canton Road & Austin Road, future developments above the KCRC’s West Kowloon Station and noise sensitive uses within the West Kowloon Cultural District, as earmarked on the relevant Outline Zoning Plans, Outline Development Plans, Layout Plans and other relevant published land use plans. Photographs of all existing NSRs shall be appended to the EIA report.
(b) 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 floor of each and every selected assessment point shall be given. For planned noise sensitive land uses without committed site layouts, the Applicant can use the relevant planning parameters to work out representative site layouts for operational noise assessment purpose. However, such assumption together with any site specific constraints identified, such as setback of building, building orientation and extended podium, shall be considered practicable, feasible and agreeable for implementation by relevant parties including the Planning Department and Lands Department as per section 6.3, Annex 13 of EIAO-TM.
(iv) Provision of an Emission Inventory of the Noise Sources
The Applicant shall provide an inventory of noise sources including representative construction equipment for construction noise assessment, and traffic flow/ fixed plant equipment (e.g. ventilation systems of traffic noise enclosures), as appropriate, for operational noise assessment. Confirmation of the validity of the inventory shall be obtained from the relevant government departments/authorities and documented in the EIA report.
(v) Construction Noise Assessment
(a) The assessment shall cover the cumulative noise impacts due to the construction works of the Project and other concurrent projects identified during the course of the EIA study.
(b) The Applicant shall carry out assessment of noise impact from construction (excluding percussive piling) of the Project during daytime, i.e. 7 a.m. to 7 p.m., on weekdays other than general holidays in accordance with the methodology 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.
(c) To minimize the construction noise impact, alternative construction methods to replace percussive piling shall be proposed as far as practicable. In case blasting works is involved, it shall be carried out, as far as practicable, outside the sensitive hours of 7 p.m. to 7 a.m. on Monday to Saturday and any time on a general holiday, including Sunday. For blasting that must be carried out during the above-mentioned sensitive hours, the noise impact from the removal of debris and rocks shall be fully assessed and adequate mitigation measures shall be recommended to reduce the noise impact.
(d) 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 tasks) to minimize the impact. If the mitigated noise levels still exceed the relevant criteria, the duration of the noise exceedance shall be given.
(e) The Applicant shall, as far as practicable, formulate a reasonable construction programme so that no work will be required in restricted hours as defined under the Noise Control Ordinance (NCO). In case the Applicant needs to evaluate whether construction works in restricted hours as defined under the NCO are feasible or not in the context of programming construction works, reference shall be made to relevant technical memoranda issued under the NCO. Regardless of the results of construction noise impact assessment for restricted hours, the Noise Control Authority will process Construction Noise Permit (CNP) application, if necessary, based on the NCO, the relevant technical memoranda issued under the NCO, and the contemporary conditions/situations. This aspect shall be explicitly stated in the noise chapter and the conclusions and recommendations chapter in EIA report.
(vi) Operational Noise Assessment
(a) Road Traffic Noise
(a1) Calculation of Noise Levels
The Applicant shall analyse the scope of the proposed road alignment(s) to identify road sections within the meaning of Item A.1 of Schedule 2 of EIAO and other road sections for the purpose of traffic noise impact assessment. Figures showing extents of road sections within the meaning of Item A.1 of Schedule 2 of EIAO and other road sections shall be provided in the EIA report. In determining whether the traffic noise impact due to a road improvement project/ work is considered significant, detailed information with respect to factors including change of nature of road, change of alignment and change of traffic capacity or traffic composition etc. shall be assessed. The traffic noise impact shall be considered significant if the traffic noise level with the road project is greater than that without the road project at the design year by 1.0 dB(A) or more.
The Applicant shall calculate expected road traffic noise using methods described in the U.K. Department of Transport's “Calculation of Road Traffic Noise” (1988). Calculations of future road traffic noise shall be based on peak hour traffic flow in respect of maximum traffic projection within a 15 years period upon commencement of operation of the Project. The Applicant shall calculate traffic noise levels in respect of each road section and the overall noise levels from combined road sections (road sections within the meaning of Item A.1 of Schedule 2 of EIAO and other road sections ) at NSRs.
The EIA report shall contain sample calculations and input parameters for at least 10 assessment points as requested by the Director. Also, the Applicant shall provide the input data set of the traffic noise model in the format of electronic files in the EIA. The Applicant shall prepare and provide drawings (i.e., road-plots of the traffic noise model) of appropriate scale to show the road segments, topographic barriers, and assessment points of sensitive receivers input into the traffic noise model.
The Applicant shall provide input data sets of traffic noise prediction model adopted in the EIA study as requested by the Director for the following scenarios:
(1) unmitigated scenario at assessment year;
(2) mitigated scenario at assessment year; and
(3) prevailing scenario for indirect technical remedies eligibility assessment;
The data shall be in electronic text file (ASCII format) containing road segments, barriers and noise sensitive receivers information. The data structure of the above file shall be agreed with the Director. CD-ROM(s) containing the above data shall be attached in the EIA report.
(a2) Presentation of Noise Levels
The Applicant shall present the existing and future noise levels in L10 (1 hour) at the NSRs at various representative floor levels in (m P.D.) on tables and plans of suitable scale.
A quantitative assessment at the NSRs for road sections within the meaning of Item A.1 of Schedule 2 of EIAO shall be carried out and compared against the criteria set out in Table 1A of Annex 5 of the TM. The potential noise impact of road sections within the meaning of Item A.1 of Schedule 2 of EIAO shall be quantified by estimating the total number of dwellings, classrooms and other noise sensitive elements that will be exposed to noise levels exceeding the criteria set in Table 1A of Annex 5 in the TM.
(a3) Proposals for Noise Mitigation Measures
The Applicant shall propose, in accordance with Section 6 in Annex 13 of the TM, direct technical remedies in all situations where predicted traffic noise level due to the road sections within the meaning of Item A.1 of Schedule 2 of EIAO, exceeds the criteria in Table 1A of Annex 5 in the TM by 1 dB(A) or more, and, under section 4.4.3 of the TM, noise from the road sections within the meaning of Item A.1 of Schedule 2 of EIAO has significant contribution to the cumulative environmental impacts which would exceed the criteria when considered in conjunction with the existing or potential impacts from other projects. The direct mitigation measures listed under Section 6.1, Annex 13 of the EIAO-TM, including the option of alternative land use arrangement, shall be thoroughly explored and evaluated with a view to reducing the noise level at the NSRs concerned to the level meeting the relevant noise criteria. Also, the feasibility, practicability, programming and effectiveness of the recommended mitigation measures should be assessed in accordance with section 4.4.2(k) of the EIAO-TM. Reasons for not adopting certain direct technical remedies in the design to reduce the traffic noise to a level meeting the criteria in the TM or to maximize the protection for NSRs as far as possible shall be clearly and specifically quantified and laid down in the EIA report.
Following the guiding principles set out in the Legislative Council Paper (LC Paper no. CB(1)755/02-03(01), copy in Appendix C) prepared by ETWB in January 2003, sections of barriers proposed to protect existing NSRs shall be differentiated clearly from those proposed for the protection of future or planned NSRs as the latter is only required to be constructed before the occupation of the planned NSRs. To facilitate the phased implementation of the barriers under this principle, a barrier inventory showing intended NSRs (i.e. existing NSRs as distinct from planned NSRs) to be protected by different barrier sections to achieve different extent of noise reduction (by how many dB(A)) should be provided.
The total number of dwellings, classrooms and other noise sensitive element that will benefit from, and be protected by the provision of direct technical remedies shall be provided. In order to clearly present the extents/locations of recommended noise mitigation measures, plans prepared from 1:1000 or 1:2000 survey maps showing the mitigation measures (e.g., enclosures/barriers, low noise road surfacing, etc.) shall be included in the EIA report.
The total number of dwellings, classrooms and other noise sensitive elements that will still be exposed to noise levels above the criteria with the implementation of all recommended direct technical remedies shall be quantified.
The Applicant shall provide, in the EIA report information of recommended noise mitigation measures (to include as least barrier types, nominal dimensions at different cross-sections, extents/locations, lengths, mPD levels of barriers) in the format as agreed by the Director (including electronic format).
In case where a number of NSRs cannot be protected by the recommended direct technical remedies, the Applicant shall identify and estimate the total number of existing dwellings, classrooms and other noise sensitive elements which may qualify for indirect technical remedies under the Executive Council Directive “Equitable Redress for Persons Exposed to Increased Noise Resulting from the Use of New Roads”, the associated costs and any implications for such implementation. For the purpose of determining eligibility of the affected premises for indirect technical remedies, reference shall be made to the following set of three criteria :
(1) the predicted overall noise level at the NSR from the road sections within the meaning of Item A.1 of Schedule 2 of EIAO together with other traffic noise in the vicinity must be above a specified noise level ( e.g. 70 dB(A) for domestic premises and 65 dB(A) for education institutions, all in L10(1hr) );
(2) the predicted overall noise level at the NSR is at least 1.0 dB(A) more than the prevailing traffic noise level, i.e. the total traffic noise level existing before the works to construct the road were commenced; and
(3) the contribution from the road sections within the meaning of Item A.1 of Schedule 2 of EIAO to the increase in predicted overall noise level at the NSR must be at least 1.0dB(A).
(b) Fixed Noise Sources
If the Project will cause any fixed noise sources, such as the ventilation systems of enclosed road sections, if any, the following assessment shall be followed.
(b1) Assessment of Fixed Source Noise Levels
The Applicant shall calculate the expected noise using standard acoustics principles. Calculations for the expected noise shall be based on assumed plant inventories and utilization schedule for the worst-case scenario. The Applicant shall calculate noise levels taking into account correction of tonality, impulsiveness and intermittency in accordance with Technical Memorandum for the Assessment of Noise from Places other than Domestic Premises, Public Places or Construction Sites issued under the NCO.
(b2) Presentation of Noise Levels
The Applicant shall present the existing and future noise levels in Leq (30 min) at the NSRs at various representative floor levels (in m P.D.) on tables and plans of suitable scale. A quantitative assessment at the NSRs for the 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.
(b3) Proposals for Noise Mitigation Measures
The Applicant shall propose direct technical remedies within the Project limits in all situations where the predicted noise level exceeds the criteria set out in Table 1A of Annex 5 of the TM to protect the affected NSRs.
(vii) Assessment of Side Effects and Constraints
The Applicant shall identify, assess and propose means to minimize any side effects and to resolve any potential constraints due to the inclusion of any recommended direct technical remedies.
(viii) Evaluation of Constraints on Planned Noise Sensitive Developments/ Land uses
For planned noise sensitive uses which will still be affected even with all practicable direct technical remedies in place, the Applicant shall propose, evaluate and confirm the practicability of additional measures including building setback within the planned noise sensitive uses and shall make recommendations on how these noise sensitive uses will be designed for the information of relevant parties.
The Applicant shall take into account agreed environmental requirements / constraints identified by the EIA study to assess the development potential of concerned sites which shall be made known to the relevant parties and/or potential developers.

(c) The Applicant shall calculate the cumulative air quality impact at the identified ASRs and compare these results against the criteria set out in section 1 of Annex 4 in the TM. The predicted air quality impacts (both unmitigated and mitigated) shall be presented in the form of summary table and pollution contours, to be evaluated against the relevant air quality standards and on any effect they may have on the land use implications. Plans of a suitable scale shall be used to present pollution contour to allow buffer distance requirements to be determined properly.
(d) If there are any direct technical noise remedies recommended in the study, the air quality implication due to these technical remedies shall be assessed. For instance, if barriers that may affect dispersion of air pollutants are proposed, then the implications of such remedies on air quality impact shall be assessed. If noise enclosure is proposed, then portal emissions of the enclosed road section and air quality inside the enclosed road section shall also be addressed. The Applicant shall highlight clearly the locations and types of agreed noise mitigating measures (where applicable), be they noise barriers, road enclosures and their portals, and affected ASR's, on contour maps for easy reference.
(vi) Mitigation Measures for Non-compliance

Any guidelines on landscape strategies, landscape frameworks, urban design concepts, building height profiles, special design areas, landmarks, designated view corridors, open space networks, landscape links that may affect the appreciation of the Project shall also be reviewed. The aim is to gain an insight to the future outlook of the area so as to assess whether the project can fit into surrounding setting. Any conflict with statutory town plan(s) and any published land use plans shall be highlighted and appropriate follow-up action shall be recommended.
188.8.131.52 The Applicant shall assess the visual impacts of the Project, in particular the visual impact of any noise barrier proposed by the EIA Study. Clear illustrations including mapping of visual impact is required. The assessment shall include :
(i) identification and plotting of visual envelope of the Project;
(ii) identification of the key groups of sensitive receivers within the visual envelope with regard to views from both ground level and elevated vantage points;
(iii) description of the visual compatibility of the Project with the surrounding and the existing and planned setting, and its obstruction and interference with the key views of the adjacent areas;
(iv) description of the severity of visual impacts in terms of nature, distance and number of sensitive receivers; and
(v) recommendation of mitigation measures to minimize adverse effects identified, including provision of a landscape design.
184.108.40.206 Annotated illustration materials such as coloured perspective drawings, plans and section/elevation diagrams, oblique aerial photographs, photographs taken at vantage points, and computer-generated photomontage shall be adopted to fully illustrate the landscape and visual impacts of the Project. In particular, the landscape and visual impacts of the Project with and without mitigation measures shall also be properly illustrated in existing and planned setting by computer-generated photomontage so as to demonstrate the effectiveness of the proposed mitigation measures. All computer graphics shall be compatible with Microstation DGN file format or as agreed with the Director. The Applicant shall record the technical details such as system set-up, software, data files and function in preparing the illustration, which may need to be submitted for verification of the accuracy of the illustrations.
3.6.6 Summary of Environmental Outcomes
The EIA report shall contain a summary of the key environmental outcomes arising from the EIA study, including the population and environmentally sensitive areas protected, environmentally friendly designs recommended, key environmental problems avoided, and the environmental benefits of environmental protection measures recommended.
4. ENVIRONMENTAL MONITORING & AUDIT (EM&A) REQUIREMENTS
