Appendix C


Measures to Mitigate Environmental Impacts from Waste Generation During Construction



At all parts of all works areas and construction sites, and throughout the full duration of the construction contract(s), the following shall be implemented:


(i)       develop procedures such as a ticketing system to facilitate tracking of marine mud and chemical waste, and to ensure that illegal disposal does not occur;

(ii)       segregate and sort the waste materials into 3 categories:

l             public fill (e.g. concrete and rubble) for re-use on-site or disposal at a public filling area;

l             re-use and/or recycling waste (e.g. steel and other metals); and

l             waste which cannot be re-used and/or recycled (e.g. wood, glass and plastic) for landfill disposal.

The sorting process shall be carefully monitored to avoid missing any of the 3 categories. Different types of wastes shall be stockpiled and stored in different containers / skips to enhance re-use or recycling of materials and their proper disposal; and

(iii)      maintain records of the quantities of wastes generated and disposed off-site for each category of waste.  Chemical waste that is produced, as defined by Schedule 1 of the Waste Disposal (Chemical Waste) (General) Regulation, shall be handled in accordance with “Code of Practice on the Packaging, Handling and Storage of Chemical Wastes” issued by the Environmental Protection Department (EPD).
