“Nature Group Seeks More Information on Impact of Cross Island Site Investigations" from Today Online, nature enthusiasts groups are inviting the community to submit queries to the Land Transport Authority (LTA), hoping to get more information on the results of drilling works done at Macritchie forest for the upcoming Cross Island MRT line(CRL) (Neo, 2018). Earlier, LTA stated that camera traps spotted the presence of animals.According to Ms Chole Tan, project manager of Love Our Macritchie Forest, nine parties have submitted questions about the possibility of LTA publicly releasing the outcomes of their monitoring programmes (Neo, 2018). Drilling of boreholes are used find out soil and rock conditions influencing the decision of the tracks going under the nature reserve or around it. An assessment was done before works started determining the environmental impact if mitigation measures were taken. But there is a lack of evidence on the effectiveness of mitigation measures. Second phase of the assessment was done to foresee the outcome of constructing and operating the MRT line. Based on the points elaborated, LTA has done the necessary measures mitigating the impact on the environment therefore LTA should go ahead with their construction plans.
Firstly, LTA have emphasized that mitigation measures will be a necessity for contractors doing site investigations. Mitigation measures which includes having enclosures to reduce the impact of noise. According to the Straits Times, Mr Chong Kee Sen, president of The Institution of Engineers said the measures implemented could successfully alleviatewater, noise, soil and other environmental impacts (Tan, 2019). In my opinion, since LTA highlighted the reduced impact with mitigation measures, the CRL construction plans can be safety carried out. LTA also reported that environmental impacts will mostly be contained to the outside of Central Catchment Nature Reserve (CCNR) and parts of the tunnel (Mahmud, 2019).
Secondly, LTA have done their necessary environmental impact assessment. As stated in LTA website, Environmental Resources Management (ERM) assesses that the environmental impact for both options can be adequately managed with comprehensive mitigation measures and monitoring plans in place (LTA, 2019). With this environmental impact assessment done, this clearly shows that LTA have evaluated their options clearly before coming to a final decision. An International Panel of Advisors (IPA), comprising industry experts in tunnelling and underground construction have analysed that with mitigation measures in place, both alignment options are safe (LTA, 2019).
Lastly, LTA have been taking all steps in making sure to mitigate potential environmental impact. According to The Straits Times, 3 hector of forest needs to be cleared to tunnel under the CCNR which will cause a loss of habitat for the wildlife (Tan, 2019). LTA said that, if mitigation measures are carried out, such as safety barriers made wildlife-friendlyand trees being re-planted, the effect of the upcoming train line on CCNR would be reduced(Tan, 2019). With this statement, LTA have showed that they will continue to make sure that environmental impact on CCNR will be taken care of even after the end of constructing of CRL. Today Online also reported that mitigation measures also includes identifying flora species so as to be able to preserve or salvaged for relocation and wildlife shepherding(Cheng, 2019).
LTA have taken all necessary mitigation measure to reduce the impact of CRL on the CCNR. LTA have also displayed that they will be responsible for the environmental impact. With these, LTA should go ahead with their construction plans.
