Environmental complaint related to Contract 3 regarding dust at Ying Hei Road (South) was referred by EPD on 24 May 2024. |
Based on the information provided by the Contractor with confirmation by RSS, water trucks and road sweepers have been deployed to clean Ying Hei Road (between Ying Tung Road and Yi Tung Road) for dust control. Wheel washing facilities were also installed and operated at the exit gate of TCE reclamation area for a thorough cleanse of car wheel before leaving the site. The dirt mentioned was likely caused by wear and tear of road pavement. Nevertheless, the Contractor would review the effectiveness of the mitigation measures and introduce enhancement as necessary. |
