The Request alleges various economic and environmental harms related to the construction, operation and maintenance of the Project, in particular:i) Economic harm linked to the expropriation process, which has limited the access to water sources on the property of the Requesters affecting their productive activities and quality of life. They also point out that the expropriation process did not correctly consider the value of land at market price.ii) Environmental harm linked to the risk of collapse of areas in the property of the Requestersthat may have been provoked or encouraged by the extraction of material from the slopes of the Reventazín River. Likewise, they point harm caused by the generation of greenhouse gases given that vegetation had not been removed prior to filling the Project reservoir.iii) Harm to the biodiversity of the area linked to the risk of collapse of the Lancaster Lagoons as an alleged consequence of the extraction work carried out on the slopes near those wetlands.
