9 Conclusions

9.01 The TLEM was started operated by Dragages at March 2016 and closed after 17 August 2017 due to the blasting work for Liantang/Heung Yuen Wai Boundary Control Point Project – Contract 2 was completed. The decommissioning phase for TLEM was scheduled in Mid of November 2017. However, due to the contractor arrangement, decommission of the magazine was idled until 21 January 2018. The actual decommission works of TLEM was commenced on 22 January 2018 and completed on 28 March 2018.

9.02 According to the approved EIA Report, operation of the existing facility will remain similar to the existing operation as described in the XRL EIA and the decommissioning works will only affect the existing TLEM which classified as developed areas of negligible ecological value, and therefore is not considered to cause any direct ecological impacts to habitats including streams or to species.

9.03 After the decommission works was completed, reinstatement planting works was undertaken according to the XRL EIA Vegetation Survey Report for Tai Shu Ha Road West and the Tree Planting and Landscape Plan TLP-10: Works in Yuen Long District (Tai Shu Ha) (Completion of Project Phase) to restore the habitat back to borrow area reinstatement plantation, as it was prior to the construction of the TLEM for the MTRC’s use.

9.04 Reinstatement planting works was commenced on 23 April 2018 and completed in July 2019 and the TLEM site had been handover to Land’s Department on 24 July 2019.

9.05 The current Project extends the operating time of the TLEM, it cause the reinstatement planting needed to be postponed by three years. The reinstatement of the TLEM is principally in order to restore the habitat back to borrow area reinstatement plantation and relative to the whole borrow area reinstatement plantation, it is a very small area. With regard to the impact of postponing the reinstatement planting by three years on habitat, this time period is relatively small with regards to vegetation succession and establishment of soils. Therefore, no adverse impact is expected on habitats.

9.06 During the operation, decommissioning and completion of project phase, 48 events of environmental site inspections were undertaken by the ET to evaluate the site environmental performance and there were no incidences of non-compliance recorded .Observations of minor deficiencies were found during regular site inspections or monthly site audits.
