to Russia. On 29 July 2006 Russia shut down oil export to Mažeikių oil refinery in Lithuania after an oil spill on the Druzhba pipeline system occurred in Russia's Bryansk oblast, near the point where a line to Belarus and Lithuania branches off the main export pipeline. Transneft said it would need one year and nine months to repair the damaged section. Although Russia cited technical reasons for stopping oil deliveries to Lithuania, Lithuania claims that the oil supply was stopped because Lithuania sold the Mažeikių refinery to Polish company PKN Orlen. Impact All IEA member countries who are net oil importers have legal obligation to hold emergency oil reserves, which is equivalent to at least 90 days of net oil imports of the previous year. Furthermore, under the EU regulations there is obligation to hold reserves equivalent to 90 days of consumption, so unlike the gas dispute with Ukraine in 2006, consumers were not affected. Poland had an 80-day oil reserve. The Czech Republic reported drawing oil from its 100-day reserves. Had the dispute prolonged, it is likely that alternative supplies would have been secured. International oil prices were not significantly affected. The involved countries have, however, expressed concerns about the reliability of the Russia-Belarus oil pipeline and Belarus as an oil middleman supplier. The events have also provoked renewed discussion on the government policy of phasing out nuclear power in Germany. Reaction The European Union has demanded an "urgent and detailed" explanation, according to a spokesman for Energy Commissioner Andris Piebalgs. Piotr Naimski, Poland's deputy economics minister who is responsible for energy security, stated "This shows once again that arguments among various countries of the former Soviet Union between suppliers and transit countries mean that these deliveries are unreliable from our perspective." German Economy Minister Michael Glos stated that the dispute showed that "one-side dependencies must not be allowed to develop." Following a meeting with European Commission President José Manuel Barroso in Berlin, German Chancellor Angela Merkel condemned the action, stating "It is not acceptable when there are no consultations about such actions". Commenting on the importance of trust in energy security, she said "That always destroys trust and no trusting, undisturbed cooperation can be built on that." Merkel continued by saying "We will certainly say to our Russian partners but also to Belarus that such consultations are the minimum when there are problems, and I think that
