Decree 74/2011, from the Government of Aragon, modifies the annexes of Law 7/2006, on environmental protection in Aragon. These modifications are made to adapt the law to the new environmental and technical requirements that have arisen since its approval. The most significant changes include the introduction of new cases in the annexes related to the environmental assessment of plans, programs, projects, and installations. Additionally, modifications are made to the annexes that contain activities requiring environmental impact assessment, and new cases are added to the annex of activities exempt from environmental licensing. The decree came into effect on April 6, 2011. [Extracted from the article]
