EIA/SEA - Basic Information and Legislation

Defined plans and conceptions whose implementation could seriously impact the environment are subject to the Environmental Impact Assessment process. The purpose of this process is to obtain an objective, professional foundation for issuing decisions and, where appropriate, measures on the basis of separate regulations such as the Construction Act, and to thereby contribute to sustainable development.

The Environmental Impact Assessment, or EIA – the assessment process evaluates all expected direct and indirect effects of a given project (structures, technology) on all parts of the environment. The method and the assessment process are governed by the Environmental Impact Assessment Act. More information can be found at EIA/SEA – information on assessed activities.

The Strategic Environmental Assessment, or SEA is likewise governed by the Environmental Impact Assessment Act. The principle behind the SEA is to find the most acceptable solution in terms of an area’s comprehensive development, meaning socio-economic development in line with maintaining high environmental quality. It thus is an assessment of strategic decisions – programs, policies, plans and designs for the given area’s development, setting the framework for subsequent completion of specific structures and projects. More information can be found at EIA/SEA – information on assessed activities.

Legislation and Competences

Assessments of the environmental impact of plans and concepts are governed by Act 100/2001 Coll., on Environmental Impact Assessment, and amendments to other laws ( Environmental Impact Assessment Act), as amended.

Impact on public health and the environment is assessed, including impact on animals and plants, ecosystems, soil, the mineral environment, water, air, climate and landscape, natural resources, property and cultural heritage and their interactions and interconnections.


The Regional Authority’s competences are governed by Sec. 22 of the Environmental Impact Assessment Act. The Regional Authority assesses those projects set out in Column B of Annex 1 to the Environmental Impact Assessment Act, and changes to them. Furthermore, it assesses projects listed in Annex 1 to the Act which are below relevant limits, if they are mentioned, and projects which the nature conservation authority believes, according to an opinion that they have issued pursuant to separate legislation, can separately or in conjunction with other elements significantly impact Sites of Community Importance or Special Protection Areas. It assesses conceptions in cases where the affected area lies entirely within the Region.

The Regional Authority:

  • Maintains records of statements it has issued and forwards one copy of each of its conclusions from fact-finding procedures and each of its statements to the Ministry of Environment for summary archival.
  • Publishes, for each calendar year, a list of expert opinions and who prepared them and also a list of concepts and who considered them
  • Issues an environmental impact assessment for the master plan and is the concerned authority when it is prepared

The EIA process is described in detail in the “Get Things Done” section.
