The complaint was in relation to construction noise nuisance in the vicinity of Tung Chung New Development Pier. According to the complainant, construction noise was generated at the HKBCF site near Hong Kong SkyCity Marriott Hotel during night-time period of the past 10 days. After investigation, it was concluded that the complaint was not relevant to Contract No. HY/2013/04. Nevertheless, the Contractor is reminded that no construction site activities during restricted hours are permitted without a valid construction noise permit issued for the specific works, and that application to EPD for such permit is required in advance.
No notification of summons or prosecutions was received during the reporting period.
Statistics on notifications of summons and successful prosecutions are summarized in Appendix I.
According to the environmental site inspections undertaken during the reporting period, the following recommendations were provided:
ˇ The Contractor was reminded to provide water spraying for the haul road regularly to prevent fugitive dust emission.
ˇ The Contractor was reminded to provide maintenance to a drilling machine to prevent emission of black smoke.
ˇ The Contractor was reminded to provide drip trays for chemical containers.
ˇ The Contractor was recommended to clear any soil contaminated by oil stain and handle it as chemical waste.
ˇ The Contractor was reminded to clear the stagnant water regularly or implement measures for prevention of stagnant water accumulation to prevent mosquito breeding.
A summary of the Implementation Schedule of Environmental Mitigation Measures (EMIS) is presented in Appendix E. Most of the necessary mitigation measures were implemented properly.
With implementation of the recommended environmental mitigation measures, the contract’s environmental impacts were considered environmentally acceptable. The weekly environmental site inspections ensured that all the environmental mitigation measures recommended were effectively implemented.
The recommended environmental mitigation measures, as included in the EM&A programme, effectively minimize the potential environmental impacts from the contract. Also, the EM&A programme effectively monitored the environmental impacts from the construction activities and ensure the proper implementation of mitigation measures. No particular recommendation was advised for the improvement of the programme.
