Like the Belo Monte project, the São Luiz do Tapajós plant project (in the Tapajós river) and the Teles Pires plant project (in the Teles Pires river, which flows into the Tapajós river) have been challenged in court for failing to have adequately consulted local people and for misguided integrated environmental assessments. They have also been accused of carrying out deforestation and agricultural advancement.
A l'igual que el projecte Belo Monte, el projecte de la planta de São Luiz do Tapajós (al riu Tapajós) i el projecte de la planta Teles Pires plant (al riu Teles Pires, que és un afluent del primer) ha estat qüestionat davant dels tribunals per no haver consultat els habitants de la regió i per avaluacions mediambientals integrades poc encertades.
