Cross City Tunnel: modifications to the tunnel control centre: review of environmental factor

It has been determined that the building proposed for the tunnel control centre cannot be constructed on site 3A and after assessment of options the Roads and Traffic Authority (RTA) has decided to seek modification of the approved Cross City Tunnel project. The proposed modification is to relocate two of the three stories proposed for site 3A which would accommodate the tunnel control centre supervisory facilities onto the adjacent site 2A. A singe storey building would be constructed on site 3A to primarily accommodate maintenance facilities. This review of environmental factors considers the environmental impacts of the proposed modification. It presents details of the proposal assesses the existing natural and social environments, describes the potential impacts on the environment and presents safeguards to minimise and or avoid these identified impacts.

经核实，拟用于隧道控制中心的建筑无法在3A场地内修建；经对多个方案进行评估后，道路与交通管理局（Roads and Traffic Authority，RTA）已决定申请对已获批的跨城市隧道工程进行变更。本次拟实施的变更内容为：将原计划在3A场地修建、用于安置隧道控制中心监控设施的三层建筑中的两层，搬迁至相邻的2A场地。同时将在3A场地修建一座单层建筑，主要用于安置运维设施。本次环境因素审查将针对本次拟变更方案的环境影响展开：本报告将详述该变更方案，评估项目周边现有自然与社会环境，分析其可能对环境造成的潜在影响，并提出用于最小化乃至规避上述已识别环境影响的防护措施。
