Law 21/2013 establishes two environmental assessment procedure—one for those projects with lower environmental impact and another for those activities with a greater environmental impact. In addition, there are two procedures for each type of assessment—a regular procedure and a simplified procedure. Generally a regular environmental impact assessment procedure is required for projects listed in Annex I to Law 21/2013, and a simplified environmental impact statement is required for projects listed in Annex II to Law 21/2013. The regular environmental impact procedure ends with an Environmental Impact Statement (Declaracion de Impacto Ambiental) that includes conditions for project development as well as monitoring conditions. The simplified procedure ends with an Environmental Impact Report (Informe de Impacto Ambiental), which also contains performance conditions and monitoring conditions.
