Types of projects that need an EIA

The 2017 regulations divide projects into 2 different types: Schedule I projects and Schedule II projects.

Schedule I projects

Schedule I projects always require an EIA. These include large scale projects with obvious environmental effects, such as:

  • crude oil refineries
  • nuclear generating stations and other nuclear reactors
  • larger scale quarries and open-cast mines

Schedule II projects

Schedule II projects will only require EIA if it's decided that the project is likely to have 'significant' environmental effects. There will usually be a threshold to determine if a case by case screening decision is required.

Examples of Schedule II projects include:

  • industrial estate development projects (threshold - the area of the development exceeds 0.5 hectare)
  • an electric line installed above ground (threshold - with a voltage of 132 kilovolts or more)
