Note:

1 Application of Environmental Permit (EP) will be supported by this EIA Study.

2 Application of EP will be supported by a separate Schedule 2 EIA Study or separate Direct Application of EP to be conducted by the respective project proponent.

3 There is no design information for EFs provided from the operator at the time of assessment. The assumption of a 400 kV electricity substation, a Schedule 2 DP under EIAO, is considered in this EIA study.

1.5.1.3 Apart from the Schedule 2 DPs presented in Table 1.1, there are a number of non-DP elements in the RODP as summarised in Table 1.2. Details are presented in Section 2.

1.5.1.4 As confirmed with Fill Management Division of CEDD, control measures would be implemented to restrict the public dumping area at the Public Fill Transfer Facility (PFTF) at TKO 132 to within 2 ha. Hence, PFTF will not constitute a designated project under item C.11, Part I, Schedule 2 of the EIAO.

1.5.1.5 The Concrete Batching Plant (CBP) at TKO 132 would have a total silo capacity of less than 10,000 tonnes, in which cement is handled or produced. Therefore, CBP will not constitute a designated project under Item K.5, Part I, Schedule 2 of the EIAO.

1.5.1.6 If there are any future change(s) after the approval of this EIA Report, the following steps will be taken:

(a) Should the change(s) involve a DP item under Schedule 2 of the EIAO, the requirements under the EIAO will be complied with; and

(b) Should the change(s) not involve any DP items under Schedule 2 of the EIAO, prevailing planning mechanisms and standards will be followed and relevant EIA findings will be conformed to.

1.6 Purpose of the EIA Study

1.6.1.1 The purpose of this EIA study is to provide information on the nature and extent of environmental impacts arising from the construction and operation stages of the Project and associated activities that will take place concurrently.

(b) the conditions and requirements for the detailed design, construction and operation of the Project to mitigate against adverse environmental consequences wherever practicable; and

1.7 Objectives of this EIA Study

1.7.1.1 The objectives of the EIA study as stated in the EIA Study Brief (No. ESB-360/2023) are as follows:
