two state enterprises in transportation of oil "Main oil pipeline "Druzhba" and "Cisdnieper main oil pipeline". The pipelines were often used by Russian companies, but after Ukraine built connecting pipeline Odessa – Brody (Black Sea coast – West Ukraine) Russian companies installed an alternative pipe route Sukhodolnaya–Rodionovskaya. In 2001 several Ukrainian parliamentarians made inquiry to the Prosecutor's General Office, Tax Agency, and Security Service requesting to open a criminal case against the head of Presidential Administration Volodymyr Lytvyn, the former chairman of Naftogaz Ihor Bakai, the administration chairmen of joint-stock company "Ukrgasprom" Bohdan Kliuk, the director of state enterprise "Ukrgasprom" Illia Fik, and others. Those parliamentarians were Hryhoriy Omelchenko, Anatoliy Yermak, and Viktor Shyshkin. As of 31 December 2008, Naftogaz with its subsidiaries had a total of 172,000 employees. Naftogaz received more than $6 billion of subsidies in domestic bonds from 2009 to 2012 as regulated gas prices and expensive Russian energy imports led to heavy losses. 2014–present In August 2014, Ukrtransgaz, the operator of the Ukrainian gas transport system, along with its Slovakian counterpart "Eustream", launched natural gas supplies from Slovakia to Ukraine after signing a Memo of mutual understanding in April. This initiative was driven by Russia's decision in June to cease gas supplies to Ukraine in retaliation for the country seeking closer ties with the European Union. By launching reverse flows, Ukraine claims it is seeking no concessions – only implementation of existing EU law on EU territory. The Third Energy Package was proposed by the European Commission in 2007 and adopted by the European Parliament and the Council of the European Union in July 2009. This legislation clearly allows for gas to be traded like other commodities, thus creating a more efficient market which is less vulnerable to political pressure. In October 2014 the EU further committed to better connecting its energy grids, saying countries should be able to export 15% of their generation capacity by 2030. The consultancy firm Strategy& (formerly Booz & Co) believes the EU could save €40bn a year by 2030 if it integrates its energy grids. Slovakia can provide more gas than Ukraine needs. In 2013, Ukraine imported 25.8bcm. Slovakia could provide Ukraine with 30bcm. Ukraine is asking that the EU fully support west-to-east exports to Ukraine, which would eliminate the scope for Russia to use gas as a weapon to achieve its political aims in Ukraine.
