3.5.2 Noise Impact
184.108.40.206 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.
220.127.116.11 The noise impact assessment shall include the following :
(i) Determination of Assessment Area
The "Assessment Area" for the noise impact assessment shall include all areas within 300m from the boundary of the scope of EIA study as defined in section 3.2.1 above and all areas within 300m from proposed road works, e.g. Road P1, Road D1, Road D2, Road D4, etc., that extend beyond the limit of the Outline Concept Plan indicated in Appendix I. 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 boundary of the scope of EIA study as defined in section 3.2.1 above, provides acoustic shielding to those receivers at further distance behind.
(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 involved in the planning standards, e.g. those for planning of fixed noise sources, 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 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.
(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 floors of each and every selected assessment point shall be given. For planned noise sensitive land uses without committed site layouts, the Applicant should use the relevant planning parameters to work out site layouts for operational noise assessment purpose.
(iv) Provision of an Emission Inventory of the Noise Sources
The Applicant shall provide an inventory of noise sources (e.g. construction equipment for construction noise assessment; etc. as appropriate, for operational noise assessment). For roads, the inventory shall include the road traffic data. Confirmation of the validity of the inventory shall be obtained from the relevant government departments/authorities.
(v) Construction Noise Assessment
(a) The Applicant shall carry out assessment of noise impact from construction (excluding percussive piling) of the project 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.
(b) To minimise the construction noise impact, alternative construction methods to replace percussive piling shall be explored and recommended as far as practicable. In case blasting cannot be avoided, it should 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 should be fully assessed and adequate mitigation measures should be recommended to reduce the noise impact as appropriate.
(c) 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 minimise the impact. If the mitigated noise levels still exceed the relevant criteria, the duration of the noise exceedance shall be given.
(d) In case the applicant would like to evaluate whether construction works in restricted hours as defined under the Noise Control Ordinance (NCO) are feasible or not in the context of programming construction works, reference should be made to the relevant technical memoranda issued under the NCO. Regardless of the results of the construction noise impact assessment for restricted hours, the Noise Control Authority will process the 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 should be explicitly stated in the noise chapter and the conclusions and recommendations chapter in the EIA report.
(vi) Operational Noise Assessment
(a) Rail Noise
(a1) The Applicant shall assess the impacts due to the operation of the proposed East Kowloon Line railway and the associated facilities within the "Assessment Area", with respect to the acceptable levels contained in Table 1A in Annex 5 in the TM issued under the EIAO. The assessment methodology including the railway/train design noise level, shall be agreed with the Director prior to the commencement of the assessment.
(a2) In assessing the noise level, the Applicant shall take into consideration of deterioration in rail and rolling stock condition from brand new to an operating level, the worst case scenario and any other planned noise source. Quantitative assessment at the identified NSRs for different alignment of the rail shall be compared against the relevant criteria or limits.
(a3) Based on the above noise assessment result, the Applicant shall define the constraints including assumed configuration of the railway (e.g. underground, viaduct or at grade), and recommend noise mitigation measures to ensure the predicted cumulative noise level at any existing or planned NSR is within the relevant planning criteria and statutory limits in the appropriate design year.

(b4) The Applicant shall propose direct mitigation measures within the project limits in all situations where predicted noise level exceeds criteria set out in Table 1A of Annex 5 of TM to protect affected NSRs.
(c) Road Traffic Noise
(c1) Calculation of Noise Levels
The Applicant shall analyse the scope of the proposed road alignment(s) to identify appropriate new and existing road sections for the purpose of traffic noise impact assessment. When an existing road section in the form of at-grade or elevated road undergoes major extensions or improvements irrespective of whether the extensions or improvements are attaching to or separate from the existing road which will directly result in 25% increase in lanes or substantial changes in alignment or character (e.g. change to a high speed road) of the existing road, it shall be regarded as a new road for the purpose of this noise impact assessment. This is particularly relevant to road links between the proposed SEKD developments and the existing urban areas.
The Applicant shall calculate the 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 the peak hour traffic flow in respect of the maximum traffic projection within a 15 years period upon commencement of operation of the proposed roadwork. The Applicant shall calculate traffic noise levels in respect of each road section and the overall noise levels from combined road sections (both new and existing) at NSRs.
(c2) Presentation of Noise Levels
The Applicant shall present the prevailing and future traffic noise levels in L10, (1hr) at the NSRs in the following formats:-
- on tables and plans of suitable scale at various representative floors levels (in m P.D.);
- on histograms showing the number of dwellings in noise sensitive development areas against the corresponding predicted noise levels of suitable scale; and
- on noise contour maps of predicted noise levels of suitable scale at low, medium and high levels. The preparation of noise contour shall take into account road traffic noise sources and all relevant topographic elements including building, podium, terrain, etc.
Quantitative assessment at NSRs for proposed road alignment(s) shall be carried out and compared against criteria in Table 1A of Annex 5 in the TM. Potential noise impact of proposed road alignment(s) shall be quantified by estimating total number of dwellings, classrooms and other noise sensitive elements that will be exposed to noise levels exceeding criteria in Table 1A of Annex 5 in the TM.
(c3) Proposals for Noise Mitigation Measures
The Applicant shall present the predicted traffic noise levels in L10, (1hr) at the NSRs for various scenarios of noise mitigation measures including alternative land uses in the following formats:-
- on tables and plans of suitable scale at various representative floors levels (in m P.D.);
- on histograms showing the number of dwellings in noise sensitive development areas against the corresponding predicted noise levels of suitable scale; and
- on noise contour maps of predicted noise levels of suitable scale at low, medium and high levels. The preparation of noise contour shall take into account road traffic noise sources, all relevant topographic elements including building, podium, terrain, etc., and proposed noise mitigation measures.
After rounding of the predicted noise levels according to the U.K. Department of Transport's "Calculation of Road Traffic Noise" (1988), the Applicant shall propose direct technical remedies in all situations where the predicted traffic noise level exceeds the criteria set in Table 1A of Annex 5 in the TM by 1 dB(A) or more. Specific 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 the NSRs as far as possible should be clearly quantified and laid down. The total number of dwellings, classrooms and other noise sensitive element that will be benefited by the provision of direct technical remedies should be provided.
The total number of dwellings, classrooms & other noise sensitive elements still exposed to noise above criteria with implementation of all recommended direct technical remedies shall be quantified.
In case where a number of the NSRs cannot all 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 the 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 from the new road 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(1 hr));
(2) the predicted overall noise level 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 to the increase in the predicted overall noise level from the new road must be at least 1.0dB(A).
(d) Helicopter Noise Impacts
(d1) The Applicant shall predict the noise impacts arising from the operation of the proposed helipad and related off site facilities with respect to the criteria set in Table 1A of Annex 5 of the TM issued under the EIAO.
