A consortium of companies plans to install a uranium and phosphate mining in Ceará (Brazil), a project that has been called Santa Quitéria Project. The enterprise may bring with it a set of rights violations. Currently, it undergoes an environmental licensing process within the scope of the Brazilian Institute for the Environment and Renewable Natural Resources (IBAMA). Due to lack of public discussion on the project and on its impacts and risks that it can cause to social and environmental rights, this letter aims at summarizing information on its main irregularities and at summoning national and international support in requesting to IBAMA’S DIRECTORS for technical, ethical and political responsibility to reject the environmental licensing of uranium and phosphate mining in Ceará.
