l The Waste Management Plan (WMP) shall prepared by the Contractor
to describe arrangements for waste avoidance, re-use and recycling, including
all handling, storage and transfer requirements. l The WMP should be refined and updated as more detailed information is generated on the volume of dredged marine mud. Similarly, it should be regularly reviewed and updated at least monthly throughout construction. |

material shall be cleaned from the decks and exposed fittings of barges and
dredgers before the vessel is moved. l 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 EPD. l Barges or hopper barges shall not be filled to a level that would cause the overflow of materials or sediment-laden water during loading or transportation. |

from chemical wastes. The general
refuse storage area shall be regularly maintained by a reputable waste
collector, with waste to be disposed at a designated refuse transfer station. l The Contractor shall be responsible for identifying which
materials can be recycled / reused, whether on site or off site. In the event
of the latter, the Contractor shall make arrangements for the collection of
the recyclable materials. Separate
labelled bins for their deposit shall be provided if feasible. l The Contractor is required to maintain a clean and hygienic site
throughout the Project. |
