S6.7.2	In order to ensure that all waste is disposed of in an appropriate manner, waste shall be separated by category on‑site by the Contractor. It is recommended that waste shall be segregated into the following defined categories and shall then be disposed of as follows: · inert portion of C&D material, that is, public fill, deemed suitable for reclamation or land formation shall be re-used on site as far as possible and the surplus material disposed of at reclamation or public filling areas; · non-inert portion of C&D material, that is, C&D waste, deemed unsuitable for reclamation or land formation shall be disposed of at landfill; · chemical waste as defined by Schedule 1 of the Waste Regulations (Chemical) 1992, shall be stored in accordance with approved methods defined in the Regulations and the chemical waste disposed of at the Chemical Waste Treatment Centre located at Tsing Yi; · excavated sediment shall be disposed of at the East Sha Chau contaminated mud pits in accordance with WBTC No. 3/2000; and · general refuse shall be disposed of at landfill.	Work site / During the construction period	Contractor		3			-
S6.7.3, S6.7.4, S6.7.5	· C&D materials should be recycled or reused wherever possible. Demolition material arising from the site clearance of existing IEC, Rumsey Street Flyover downramp and Hing Fat Street Flyover should be broken down to 250 mm in size in order to facilitate reuse and recycling. Steel reinforcement should be removed from the demolition material prior to disposal and reused or recycled. · The waste management strategy to be employed shall be waste minimisation at source. Where waste generation is unavoidable then the potential for recycling or reuse shall be explored and opportunities taken. If wastes cannot be recycled, then the recommended disposal routes shall be followed. · Waste reduction measures shall be introduced at the design stage and carried through the construction activities, wherever possible, by careful purchasing control, reuse of formwork and good site management. · Training and instruction of construction staff shall be given at the site to increase awareness and draw attention to waste management issues and the need to minimise waste generation. The training requirements shall be included in the site Waste Management Plan.	Work site / During the construction period	Contractor		3			-

Work site / During the construction period	Contractor		3			-
S6.7.7	It is recommended that: · wastes shall be handled and stored in a manner that ensures that they are held securely without loss or leakage thereby minimising the potential for pollution. Release of these potential pollutants into marine waters during storage and handling shall not be permitted as introduction of polluted waters is likely to have detrimental effects on water quality and water sensitive receivers; · only reputable waste hauliers authorised to collect the specific category of waste concerned should be employed; · removal of demolition material shall coincide with the demolition work; · prior to disposal of C&D waste, it is recommended that wood, steel and other metals shall be separated for re-use and / or recycling to minimise the quantity of waste to be disposed of to landfill; · appropriate measures shall be employed to minimise windblown litter and dust during transportation by either covering trucks or transporting wastes in enclosed containers; · the necessary waste disposal permits shall be obtained from the appropriate authorities, if they are required, in accordance with the Waste Disposal Ordinance (Cap. 354), Waste Disposal (Chemical Waste) (General) Regulation (Cap. 354) and the Land Ordinance; · collection of general refuse shall be carried out frequently, preferably daily; · waste shall only be disposed of at licensed sites and the site staff and Contractor shall develop procedures to ensure that illegal disposal of wastes does not occur; · waste storage areas should be well maintained and cleaned regularly; · a recording system for the amount of wastes generated, recycled and disposed of off-site during the implementation of the project.

S6.6.11 S6.7.9	To determine the disposal requirements of the excavated sediments, sediment sampling and testing are required to be carried out at the design phase of the Project. In accordance with WBTC No. 3/2000, the contaminated excavated sediment must be effectively isolated from the environment upon final disposal and shall be disposed of at the East Sha Chau Contaminated Mud Pits that is designated for the disposal of contaminated mud in Hong Kong. During transportation and disposal of the excavated marine sediments, the following measures should be taken to minimise potential impacts on water quality. · Bottom opening of barges shall be fitted with tight fitting seals to prevent leakage of material. Excess material shall be cleaned from the decks and exposed fittings of barges and hopper dredgers before the vessel is moved. · Monitoring of the barge loading shall be conducted to ensure that loss of material does not take place during transportation. Transport barges or vessels shall be equipped with automatic self-monitoring devices as specified by the DEP.	Work site / During the construction period	Contractor		3			WBTC No. 3/2000
