The European Commission urged Bulgaria to assess the possible impact of wind turbines and other projects in protected areas of Kaliakra region, in the northeast of the country.
"Bulgaria has authorised a high number of economic activities in the Kaliakra area without appropriate environmental impact assessment, and is continuing to do so. Thousands of wind turbines and some 500 other projects have been authorised without adequate assessments of their effect on Kaliakra's unique habitats and species," the Commission said in a statement published on its website on Thursday.
According to the commission, no account is being taken of the cumulative effect of the projects, which is a requirement under the Birds, Habitats and Environmental Impact Assessment Directives of the EU.
If Bulgaria fails to comply with the EU nature protection legislation within two months, the commission may refer the case to the Court of Justice and ask for interim measures as well as for the removal of the wind power projects.
