On 15 March 2007, Russia, Greece and Bulgaria signed an inter-governmental agreement on the construction of the Burgas – Alexandroupolis pipeline. The Burgas – Alexandroupolis pipeline is a cross border oil pipeline that will link the Bulgarian Black Sea port of Burgas with the Greek Mediterranean port of Alexandroupolis. The pipeline will be 280 km long, and will transport 35 million tons of crude oil during the first phase and 50 million during the second. It is estimated that construction will be completed by 2009-2010. The European Commission has supported the construction of this pipeline as it is expected to reduce maritime oil transport through the Bosphorus and Dardanel straits, thus reducing the risk of environmental disaster caused by oil spills.
