safety laws during a series of incidents which occurred in 2000. Ineos went to court in April 2008 over claims that it had polluted the River Forth in mid-2007. Ineos industrial disputes In 2008, Ineos proposed that plant workers start contributing a share towards their own pensions (a final salary pension scheme), instead of the existing non-contributory fixed salary pensions. The request would have obliged future new entry employees to pay 6% of their salary, phased in over a six-year period. 97% of the Unite trade union's 1,250 members at Grangemouth voted in favour of strike action. David Watt, of the Institute of Directors in Scotland, stated that the average Grangemouth Refinery plant worker earns £40,000 per year (nearly twice the Scottish average.) This was disputed by the Deputy General Secretary of the Scottish Trades Union Congress, Dave Moxham, who stated that they earn £30,000 per year. The strike began on 27 April 2008, and lasted until 29 April. The petrol supply of Scotland was affected by the strike, as panic buying led some petrol stations across the country to run dry. The Retail Motor Industry Federation stated that there was a stock of fuel that could last 70 days, easily covering the lapse in production so long as no panic buying occurred. With the shutdown of the plant, BP closed the Forties pipeline system as their Kinneil terminal relies on power from the Grangemouth refinery. With the shutdown of Kinneil, 70 North Sea oil platforms were forced to shut down or reduce production, at the cost of . Shutting the pipeline down reduced Britain's petroleum supply (the Forties pipeline provides 30% of the UK's North Sea oil), and cost the UK economy £50 million in lost production every day it remained closed. There was further industrial action in 2013. Ineos stated that the plant was making losses, and offered a survival plan requiring employees to accept worse employment terms, particularly on pensions, which the employees rejected. Ineos stated in October 2013 that the petrochemical works would close. Following negotiations led by Scottish Finance Secretary John Swinney and Scottish Secretary Alistair Carmichael, on 24 October the unions accepted a survival plan put forward from the management of the plant. On 25 October 2013, it was announced the plant will stay open and Unite had agreed to taking no strike action for three years, moving to a new pension scheme and
