In response to Section 4.4.2(h) of the TM, the Applicant shall review and consider any lessons learnt from other similar projects for incorporation in the current proposal to minimise potential noise impacts.
188.8.131.52 The study area shall include all areas within a distance of 300m from the Project boundary and of all work sites proposed under the Project. The study area may 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 located further away. In this case, the study area shallbe agreed with the Director. Subject to the agreement of the Director, the assessment area shall be expanded to include NSRs at greater distance which would be affected by the construction and operation of the project.
184.108.40.206 Provision of Background Information and Existing Noise Levels:
(i) The Applicant shall provide all background information relevant to the Project, including relevant previous or current studies. Unless required for determining the planning standards, such as those for planning of fixed noise sources, no existing noise levels are required except as set out below.
(ii) For ground-borne noise impact, the background information and existing noise levels shall be measured and described in a way sufficient for identification and prediction of noise impacts, and for formulation of noise criteria. Where necessary, baseline noise surveys shall be carried out to determine the existing noise conditions inside NSRs likely to be affected during the construction and operation of the Project. The type and duration of baseline surveys shall define the existing conditions by collecting/ including adequate information to take full account of natural variations. Where appropriate, results from relevant past studies should be used.
220.127.116.11 Identification of Noise Sensitive Receivers
(i) 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 earmarked on the relevant Outline Zoning Plans, Outline Development Plans and Layout Plans. For planned noise sensitive land uses without committed site layouts for operational noise assessment purpose, based on the relevant planning parameters.
(ii) The Applicant shall select assessment points to represent all identified NSRs for carrying out quantitative noise assessment as described below. The assessment points shall be agreed with the Director prior to the quantitative noise assessment. A map shall be given showing the location of each and every selected assessment points.
18.104.22.168 An inventory of noise sources including representative construction equipment assumed for assessing construction noise associated with, for example tunneling and other construction works, and plant/ equipment/ railway/ rolling stock for operation noise assessment shall be provided. The inventory shall assume appropriate railway traffic data for the purpose of assessment.
22.214.171.124 Construction Noise Assessment:
(i) Based on best information, the assessment shall cover the cumulative noise impacts due to the construction works of the Project and other projects in the vicinity, such as but not limited to, the proposed Optimized Shatin to Central Link (SCL) Conforming Scheme - North South Railway Corridor (Mong Kok to Central South), Harbour Area Treatment Scheme (HATS), and the Drainage Improvement in Northern Hong Kong Island Project.
(ii) 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.
(iii) For ground-borne noise impacts, the criteria and assessment methodology shall be agreed with the Director (with reference to Section 4.4.2(c) of the TM. Site measurements at appropriate locations may be required in order to obtain the empirical input parameters required in the ground-borne noise model.
(iv) To minimize the construction noise impact, alternative construction methods to replace percussive piling and blasting shall be proposed as far as practicable. In case blasting cannot be avoided, it should be carried out, as far as practicable, outside the sensitive hours (7pm to 7am 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 associated with the removal of debris and rocks should be fully assessed and adequate mitigation measures should be recommended to reduce the noise impact as appropriate. Also, a mechanism should be recommended in the EIA Report such that the blasting schedule should be submitted to the concerned authority for approval prior for its implementation.
(v) For tunneling, noise impact (including air-borne noise and ground-borne noise) associated with the operation of powered mechanical equipment, in particular, tunnel boring machines or equivalent, shall be assessed. If the equipments, such as a tunnel boring machine, is used and it is likely that NSRs in the vicinity will be affected by the resultant ground-borne noise, the methodology/ model for assessing ground-borne noise shall be agreed with the Director prior to obtaining the empirical parameters required in the ground-borne noise model. Cumulative impacts with other projects shall be covered if appropriate.
(vi) If the unmitigated construction noise levels are found to exceed the relevant criteria, the Applicant shall propose practicable direct mitigation measures (including but not limited to movable barriers, enclosures, quieter alternative methods, re-scheduling and restricting hours of operation of noisy tasks), particularly at open-cut areas and tunnel portal, to minimize the impact. If the mitigated noise levels still exceed the relevant criteria, the duration of the noise exceedance shall be given.
(vii) The Applicant shall formulate a reasonable construction programme as far as practicable such that no work wil be required in the restricted hours as defined under the Noise Control Ordinance (NCO). In case the Applicant needs to evaluate whether construction works during restricted hours as defined under the 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 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 condition/situations of adjoining land uses and any previous complaints against construction activities at the site before making his decision in granting a CNP. This should be explicitly stated in the noise chapter and the conclusions and recommendations chapter in the EIA report.

(iv) The Applicant shall make recommendations for noise amelioration/direct technical remedies for any existing or planned NSR which would be subject to predicted cumulative noise level in excess of the relevant planning criteria or 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.

Best management practices shall be recommended to reduce any potential impacts arising from stormwater runoff during both construction and operation phases.
* Note: The model areas specified in the modelling specification focus on the Aberdeen typhoon shelter where no new effluent discharge is allowed. The project profile submitted by MTRC did not indicate location of discharge, flow rate or chemical dosing regime of the cooling system. Therefore if modelling assessment is needed, at least the aspect of model coverage has to be reviewed.
