DCAN 10: Environmental Impact Assessment

Other projects

Permanent racing and test tracks for motorised vehicles

A33 Particular consideration should be given to the size, noise impacts, emissions and the potential traffic generation. EIA is more likely to be required for developments with a site area of 20 hectares or more.

Installations for the disposal of non-hazardous waste

A34 The likelihood of significant effects will generally depend on the scale of the development and the nature of the potential impact in terms of discharges, emissions or odour. For installations (including landfill sites) for the deposit, recovery and/or disposal of household, industrial and/or commercial wastes (as defined by the Waste and Contaminated Land ( Northern Ireland ) Order 1997 Opens link in a new browser window ) EIA is more likely to be required where new capacity is created to hold more than 50,000 tonnes per year, or to hold waste on a site of 10 hectares or more. Sites taking smaller quantities of these wastes, sites seeking only to accept inert wastes (demolition rubble etc.), or Civic Amenity sites, are unlikely to require EIA.

Sludge-deposition sites (sewage sludge lagoons)

A35 Similar considerations will apply for sewage sludge lagoons as for waste disposal installations. EIA is more likely to be required where the site is intended to hold more than 5,000 cu.m of sewage sludge.

Storage of scrap iron, including scrap vehicles

A36 Major impacts are likely to be discharges to soil, site noise and traffic generation. EIA is more likely to be required where it is proposed to store scrap on an area of 10 hectares or more.

Waste-water treatment plants

A37 Particular consideration should be given to the size, treatment process, pollution and nuisance potential, topography, proximity of dwellings, and the potential impact of traffic movements. EIA is more likely to be required if the development would be on a substantial scale (e.g. site area of more than 10 hectares) or if it would lead to significant discharges (e.g. capacity exceeding 100,000 population equivalent). EIA should not be required simply because a plant is on a scale which requires compliance with the Urban Water Treatment Directive 91/271/EEC.
