Construction
Site Runoff and Drainage · Before commencing any site formation work, all sewer and drainage connections shall be sealed to prevent debris, soil, sand etc. from entering public sewers/drains. · Provision of perimeter channels to intercept storm-runoff from outside the site. These shall be constructed in advance of site formation works and earthworks. · Temporary ditches such as channels, earth bunds or sand bag barriers shall be included to facilitate runoff discharge into the stormwater drain, via a sand/silt basin/trap. · Works programmes shall be designed to minimise works areas at any one time, thus minimising exposed soil areas and reducing the potential for increased siltation and runoff. · Sand/silt removal facilities such as sand traps, silt traps and sediment basins shall be provided to remove the sand/silt particles from run-off. These facilities shall be properly and regularly cleaned and maintained. These facilities shall be carefully planned to ensure that they would be installed at appropriate locations to capture all surface water generated on site. · Careful programming of the works to minimise excavation works during the rainy season. · Temporary access roads shall be protected by crushed gravel and exposed slope surfaces shall be protected when rainstorms are likely. · Open stockpiles of construction materials on-site shall be covered with tarpaulin or similar fabric during rainstorms to prevent erosion. |

must be dredged and transported with great care. Mitigation measures, including the use of closed-grab dredgers,
shall be incorporated. · The dredged contaminated sediment must be effectively isolated from the environment upon final disposal and shall be disposed of at the East Sha Chau Contaminated Mud Pits. During
transportation and disposal of the dredged marine sediments, the following
measures shall 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. ·

nomination
of an approved personnel, such as a site manager, to be responsible for good
site practice, arrangements for collection and effective disposal to an
appropriate facility, of all wastes generated at the site; ·
training
of site personnel in proper waste management and chemical handling
procedures; ·
provision
of sufficient waste disposal points and regular collection for disposal; ·
appropriate
measures to minimise windblown litter and dust during transportation of waste
by either covering trucks or by transporting wastes in enclosed containers; ·
separation
of chemical wastes for special handling and appropriate treatment at the
CWTF; ·
regular
cleaning and maintenance programme for drainage systems, sumps and oil
interceptors; · a recording system for the amount of wastes generated, recycled and disposed of (including the disposal sites); · In order to monitor the disposal of C&D and solid wastes at public filling facilities and landfills, and control fly-tipping, a trip-ticket system should be included as one of the contractual requirements and implemented by the Environmental Team. One may make reference to WBTC No. 5/99 for details; and · A Waste Management Plan (WMP) should be prepared and this WMP should be submitted to the Engineer for approval.

Waste
reduction is best achieved at the planning and design stage, as well as by
ensuring the implementation of good site practices. Recommendations to achieve waste reduction include: ·
segregation
and storage of different types of waste in different containers, skips or
stockpiles to enhance reuse or recycling of materials and their proper
disposal; ·
to
encourage collection of aluminium cans by individual collectors, separate
labelled bins shall be provided to segregate this waste from other general
refuse generated by the work force; ·
any
unused chemicals or those with remaining functional capacity shall be
recycled; ·
use
of reusable non-timber formwork to reduce the amount of C&D material; ·
·
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; ·
proper
storage and site practices to minimise the potential for damage or
contamination of construction materials; and · plan and stock construction materials carefully to minimize amount of waste generated and avoid unnecessary generation of waste. |

Construction and
Demolition (C&D) Waste · Careful design, planning and good site management can minimize over-ordering and generation of waste materials such as concrete, mortar and cement grouts. The design of formwork should maximize the use of standard wooden panels so that high reuse levels can be achieved. Alternatives such as steel formwork or plastic facing should be considered to increase the potential for reuse. · The contractor should use as much of the C&D material as possible on-site. Proper segregation of waste types on site will increase the feasibility of certain components of the waste stream by recycling contractors. · Inert C&D material (public fill) are directed to reclamation areas, where they have the added benefit of offsetting the need for removal of materials from borrow areas for reclamation purposes, or to an approved public filling area (PFA). |

Chemical Wastes
After use, chemical wastes should be handled according to the Code of Practice on the Packaging, Labeling and Storage of Chemical Wastes. Spent chemicals should be stored and collected by an approved operator for disposal at the Chemical Waste Treatment Facility or other licensed facility in accordance with the Chemical Waste (General) Regulation. · Containers used for the storage of chemical waste should: · Be suitable for the substance they are holding, resistant to corrosion, maintained in good condition, and securely closed; · Have a capacity of less than 450 litres unless the specifications have been approved by the EPD; and · Display a label in English and Chinese in accordance with instructions prescribed in Schedule 2 of the Regulations. The storage area for chemical waste should: · Be clearly labeled and used solely for the storage of chemical waste; · Be enclosed on at least 3 sides; · Have an impermeable floor and bunding, of capacity to accommodate 110% of the volume of the largest container or 20% by volume of the chemical waste stored in that area, whichever is the greatest; · Have adequate ventilation; · Be covered to prevent rainfall entering (water collected within the bund must be tested and disposal as chemical waste if necessary); and · Be arranged so that incompatible materials are adequately separated. Disposal of chemical waste should: · Be via a licensed waste collector. ·
Be a facility licensed to receive
chemical waste, such as the Chemical Waste Treatment Facility which offers a
chemical waste collection service and can supply the necessary storage
containers; or be a reuser of the waste, under approval from the EPD. ·

General Refuse · General refuse should be stored in enclosed bins or compaction units separate from C&D and chemical wastes. A reputable waste collector should be employed by the contractor to remove general refuse from the site, separately from C&D and chemical wastes, on a daily or every second day basis to minimize odour, pest and litter impacts. ·
Office waste can be reduced through
recycling of paper if volumes are large enough to warrant collection. Participation in a local collection scheme
should be considered if one is available. |
