The Retortillo uranium mine project near Salamanca is looking to expand its area. Opposition includes very active municipalities, and two local ejos working together against the project. ENUSA and Berkeley signed an agreement in December 2008 according to which Berkeley should make a report about the viability of the exploitation of uranium in the territories of Villavieja de Yeltes and Retortillo, Salamanca, Spain, near the frontier with Portugal. In October 2011, Berkeley signed an agreement of cooperation with the town halls of Retortillo and Villavieja de Yeltes about the mine exploitation of uranium deposit and regarding a project of construction of a factory of uranium concentrates. Berkeley has deeply divided the local inhabitants opinions with the promise of offering local people between 100–200 jobs, which was appreciated by them, considering the high share of unemployed people. On September 25th 2013, the Junta (regional government) of Castilla y León issued a favourable Environmental Impact Statement of the Uranium mining project. The Nuclear Spanish Safety Council on 5th March 2014 informed Berkeley that the company submitted dossier was incomplete because the waste is radioactive and it must be treated as such, but finally Berkeley obtained the authorization as first category radioactive installation. The first category radioactive installations activities imply the highest potential radiological risk, such as the facilities producing uranium, thorium and their compounds; the facilities that produce natural uranium; the facilities that use radioactive sources for industrial irradiation uses and the complex facilities that use high radioactive substances stocks or produce irradiation bunches with such a high frequency energy that causes a significant radiological impact.
