In July 2013, the the EIB Complaints Mechanism (EIB-CM) received a complaint concerning the EIB's funding of the Port of Seville in Spain. The EIB had granted a EUR 100 million loan in 2006 to the Autoridad Portuaria de Sevilla to finance their medium term investment programme. This investment programme originally included two components - (i) a new entry lock and (ii) the deep dredging of the Guadalquivir River. The EIB only considered the first component for financing and appraised it as a "standalone project". The complainants alleged that the EIB failed to properly assess the global environmental impact of the project as well as the dredging works of the Guadalquivir River and its impact in the Doriana National Park, an important natural reserve declared a World Heritage Site by UNESCO. According to the complainants, the new entry-lock financed by the EIB and the dredging of the Guadalquivir are under no circumstance two projects independent of each other (as the EIB considered at the time of appraisal), but rather one and the same overall project.
