Management of Waste Disposal

The construction contractor will open a billing account with the EPD.  Every construction waste or public fill load to be transferred to the Government waste disposal facilities such as public fill reception facilities, sorting facilities, landfills will required a valid “chit” which contains the information of the account holder to facilitate waste transaction recording and billing to the waste producer.  A trip-ticket system will also be established to monitor the disposal of construction waste at the SENT Landfill and to control fly-tipping.  The trip-ticket system will be included as one of the contractual requirements and implemented by the contractor.

A recording system for the amount of waste generated, recycled and disposed of (including the disposal sites) will be established.

Measures for the Reduction of Construction Waste Generation

Inert and non-inert construction waste will be segregated and stored in different containers or skips to facilitate reuse or recycling of the inert waste and proper disposal of the non-inert construction waste.  Specific areas of the work site will be designated for such segregation and storage if immediate use is not practicable.

The following precautionary measures have been recommended to protect workers from potential risks:

·       During all works, safety procedures will be implemented to minimise the risks of fires and explosions and asphyxiation of workers (especially in confined space).

To protect workers from landfill gas risk

All construction works area

Extension Contractor

 

 

 

Paragraphs 8.3 to 8.49 of EPD’s Landfill Gas Hazards Assessment Guidance Note

EIAO-TM Annex 7

 

 

 

·       Safety officers, specifically trained with regard to landfill gas related hazards and the appropriate actions to take in adverse circumstances, will be present on all worksites throughout the works.

 

 

 

 

 

 

 

 

 

 

 

·       All personnel who work on site and all visitors to the site will be made aware of the possibility of ignition of gas in the vicinity of the works, the possible presence of contaminated water and the need to avoid physical contact with it.

 

 

 

 

 

 

 

 

 

 

 

·       Those staff who work in, or have responsibility for 'at risk' areas, including bore piling and excavation works, will receive appropriate training on working in areas susceptible to landfill gas.

 

 

 

 

 

 

 

 

 

 

 

·       Any offices/quarters set up on site will take precautions against landfill gas ingress, such as being raised off the ground.  Other storage premises, e.g. shipping containers, where this is not possible will be well ventilated prior to entry.

 

 

 

 

 

 

 

 

 

 

 

·       Adequate precautions to prevent the accumulation of landfill gas under site buildings and within storage shed will be taken by raising buildings off the ground where appropriate and 'airing' storage containers prior to entry by personnel and ensuring adequate ventilation at all times.

 

 

 

 

 

 

 

 

 

 

 

·       Smoking and naked flames will be prohibited within confined spaces.  'No Smoking' and 'No Naked Flame' notices in Chinese and English will be posted prominently around the construction site.  Safety notices should be posted warning of the potential hazards.

 

 

 

 

 

 

 

 

 

 

 

·       Welding, flame-cutting or other hot works may only be carried out in confined spaces when controlled by a 'permit to work' procedure, properly authorised by the Safety Officer.  The permit to work procedure will set down clearly the requirements for continuous monitoring of methane, carbon dioxide and oxygen throughout the period during which the hot works are in progress.  The procedure will also require the presence of an appropriately qualified person who shall be responsible for reviewing the gas measurements as they are made, and who shall have executive responsibility for suspending the work in the event of unacceptable or hazardous conditions.  Only those workers who are appropriately trained and fully aware of the potentially hazardous conditions which may arise will be permitted to carry out hot works in confined areas.

 

 

 

 

 

 

 

 

 

 

 

·       During the construction works, adequate fire extinguishers and breathing apparatus sets will be made available on site and appropriate training given in their use. 

 

 

 

 

 

 

 

 

 

8.6.2

LFG2

Monitoring will be undertaken when construction works are carried out in confined space within the consultation zone.  The monitoring requirements and procedures specified in Paragraphs 8.23 to 8.28 of EPD’s Guidance Note will be followed.

In the event of the trigger levels being exceeded, it is recommended that a person, such as the Safety Officer, is nominated, with deputies, to be responsible for dealing with any emergency which may occur due to landfill gas.  In an emergency situation, the nominated person, or his deputies, whall have the necessary authority and shall ensure that the confined space is evacuated and the necessary works implemented for reducing the concentrations of gas.  The appropriate organisations shall be contact.

The design of the landfill gas management system and the landfill gas precautionary measures to be adopted on-site will be done by a landfill gas specialist consultant appointed by the Extension contractor, who has comprehensive knowledge on landfill characteristics, potential landfill gas hazards and appropriate precautionary measures to minimise hazards.  Moreover, the landfill gas management system and landfill gas precautionary measures will be checked and certified by a qualified independent consultant.

During the detailed design stage, a review of this preliminary qualitative risk assessment will be carried out, a detailed qualitative landfill gas risk assessment will be prepared and the report together with the detailed design of gas protection measures will be submitted to EPD for vetting.

Good Construction Practice:

·            Fences along the boundary of the Extension Site will be erected before the commencement of works to prevent vehicle movements, and encroachment of personnel, onto adjacent areas. 

·           The work site boundaries will be regularly checked to ensure that they are not breached and that damage does not occur to surrounding areas.

·            The quantity of explosive used and the dimensions and spacings of shotholes will be carefully designed to minimise air overpressure, flyrock generation and ground-borne vibration.

·           Use of fine blast nets, screens and other protective covers to prevent the projection of flying fragments and material resulting from blasting.  The loose material and stones in the site will be removed before blasting to minimise flying fragments affecting the surrounding areas and the blasting area will also be wetted prior to blasting to minimise dust.

Indigenous plant species of shallow root system, softwood in nature and adaptive to sea shore habitat are recommended to be used in the restoration plan, which can establish well in coastal area with exposure to strong wind and salt spray, with sand soil base.  Taking consideration of the relative poor substrate and the difficulties of establishment of some native trees in Hong Kong, it is recommended to include approximately 20% of non-native tree species in the compensatory woodland.  The non-native tree species can serve as a nurse species to facilitate the establishment of the native tree species, especially the shading, and it can be replaced by established native tree species progressively.  Plant species can also make reference to food plants of butterfly species (in particularly butterfly species of conservation interests recorded within the CWBCP).

It is also recommended that a trial nursery for native plant species be set up to fine tone the planting matrix and management intensity of the recommended indigenous tree species for the restoration of the Extension.  It should be noted that native shrubs and tree species had been used for restoration of the existing SENT Landfill, native plant species that could not successfully be established on the existing SENT Landfill should be reviewed before the preparation of the compensatory planting list.  Special care and intensive management of native plant should be implemented in order to ensure proper establishment of the native plants.
