The site will also generate general domestic waste (for example, food and<br />

packaging) and office waste (mainly paper). The quantities of general waste<br />

generated during the operation will be relatively small because of the small<br />

numbers of staff employed on each shift.<br />

The incorrect disposal of these wastes could result in contamination of surface<br />

water and ground water resources and soils, which could have negative<br />

impacts on ecosystem functioning and also on human health for those living<br />

close to the dump sites. The disposal of wastes at existing dumpsites will<br />

exacerbate associated environmental problems such as windblown litter,<br />

vermin and other disease vectors. There are also health impacts related to the<br />

direct contact of waste scavengers with the disposed waste.<br />

<strong>Impact</strong> Significance<br />

The impacts during operation are likely to be experienced beyond the Project<br />

site and the immediate surroundings and are therefore considered to be<br />

regional. The impacts will be permanent, and they may persist after the<br />

operational phase. The impact magnitude is considered to be moderate.<br />

The sensitivity of the receptors is considered to be low as the receptors will be<br />

able to adapt with relative ease and maintain pre-impact status as the volumes<br />

of waste are very low.<br />

The overall impacts during operation are therefore assessed to be minor prior<br />

to the implementation of mitigation measures.<br />

7.8.3 <strong>Impact</strong> Description and Significance: Decommissioning<br />

A variety of different types of wastes will be generated by the<br />

decommissioning and demolition of infrastructure and buildings. These<br />

wastes include machinery, metal (mainly ferrous) and demolition waste<br />

including rubble and used concrete.<br />

It may be possible to sell much of the redundant machinery and electrical<br />

equipment, including cabling, from the power plant. Equipment that it is not<br />

possible to sell for reuse elsewhere will probably be sold for scrap. The<br />

majority of the ferrous metals could be sold for scrap.<br />

Lubricating, hydraulic and transformer oils from machinery, fuel and<br />

chemical containers and sludge residues may need to be removed prior to<br />

transport and disposal of the machinery. The incorrect handling and disposal<br />

of these wastes may result in the contamination of soils and water resources.<br />

Demolition wastes will comprise mainly inert materials from the fabric of the<br />

buildings but will also include wood, plastics, metals. It is possible to recycle<br />

demolition waste (rubble etc) if there is a suitable construction project or road<br />

building scheme nearby. If there are no such projects that can utilise the<br />

rubble, it may be possible to use it to form access roads or as daily cover for<br />
