Environmental Impact Assessment (EIA)

Last updated: 20 January 2011

An Environmental Statement (ES) is a developer's assessment of the environmental impact of a project. It will contain suggestions for mitigation (taking protective measures to reduce or remove this impact).

The requirement for EIA arises from Directive 85/337/EEC as transposed by The Planning (Environmental Impact Assessment) Regulations (Northern Ireland) 1999.

On certain large-scale development proposals the NIEA Development Management Team are asked by Planning Service (PS) to assess whether an EIA is required due to its environmental impact - Screening.

When PS determines that an EIA is required NIEA will advise what types of surveys and other technical information will be needed to assess the environmental impact.
This ensures that the potential impact of development proposals on all sensitive habitats, wildlife, landscapes and earth science features is fully assessed This process is known as Scoping.

To ensure that this process is carried out in an efficient and timely manner the NIEA Development Management Team recommends that:

NIEA are contacted at the earliest possible stage of a development proposal. This will allow us to advise what surveys will be required which allows the developer the opportunity to carry out surveys at the appropriate time of year.

NIEA are consulted at the scoping stage of the process so that we can advise if records are available on the site and what information will need to be provided by the developer.

Professional advice is sought from experienced qualified ecologists and/or geologists on how conservation features may be conserved and ecological enhancements may be provided.

A location plan is submitted that clearly identifies the site area with a grid reference and the site is outlined with a red line on an extract of the ordnance survey map.
