Proposed Bus Ingress/ Egress Routeing
Although the predicted levels of construction dust are well within the limits stipulated in the HKAQO, continuous surveillance of the implementation of dust mitigation measures will be carried on a weekly basis to ensure effective control of dust emissions.
As the predicted construction noise levels are within the limits stipulated in the EIA-TM, only a limited amount of daytime noise monitoring will be carried out for 30 active minutes on a bi-weekly basis. The preferred locations for noise monitoring will be at the HK Technical College (Chai Wan) and Staff Quarters, Heng Fa Chuen and Tsui Wan Estate.
EM&A for land contamination and hazard are considered not necessary during the construction phase.
The predicted off-site traffic noise impacts are insignificant provided that the following measures are taken by NWFB to reduce adverse noise impacts on the NSRs during the operational phase of the bus depot:-
- buses that run through the nearby roads will adhere to the suggested routeing prepared by the Traffic Consultant (MVA (HK) Ltd) (Figure 3.1); and
The predicted operational noise levels caused by the depot are well within the limits stipulated in the EIA-TM. However, monitoring of operational plant will be undertaken to ensure that the source terms derived for the operational noise predictions are achieved both in terms of the vendor’s sound power specifications and the operational and maintenance assumptions.
A waste management plan will be employed to minimise potential adverse impacts associated with the solid waste and wastewater arising from operation of the depot.
Auditing of each waste stream will be carried out annually by an IC (Environmental) to determine if wastes are being managed in accordance with approved procedures and the site waste management plan and to see if waste reduction could be enhanced. The audits will cover all aspects of waste management including waste generation, storage, recycling, transport and disposal.
A contamination avoidance plan will be employed to prevent land contamination associated with contaminants arising from the operation of the depot. It is proposed that leak detection equipment to monitor the interstitial space in the double skinned fuel tank will be provided.
Auditing will be carried out annually by the IC (Environmental) to determine if procedures and instructions in the contamination avoidance plan have been followed. Regular inspection, testing and checks are to be carried out on the following :
The establishment of safety management and emergency response systems for the depot operation will be adequate to reduce the likelihood of undesirable events and provide for their effective management.
With the proper design of the depot and bus routeing, the operation of the depot will not cause adverse air emission impacts on the ASRs. EM&A for air quality is considered not necessary during operational phase.
