York Moors National Park. The third producer, Irish Salt Mining and Exploration Co Ltd, operates the Kilroot mine at Carrickfergus in Northern Ireland and produced an estimated 250 000 tonnes in 2005. A proportion of the rock salt from this mine is exported to the eastern seaboard of the USA. The Winsford mine, with some 26 million cubic metres of space, has a constant temperature and humidity and is dry and gasfree. Part of the mine is currently being used for secure document storage. In addition, the mine’s Minosus waste disposal project cleared a final legal challenge in the High Court in December 2004. Limited hazardous waste disposal commenced in August 2005, pending the completion of simulated mine condition test methods that have to be approved by the Environment Agency. Approval was reached in March 2006 meaning that Minosus can now accept the full range of 42 different waste types it was designed for. To date input has been running at around 15% of capacity but is expected to double during the course of this year. Strict criteria will be used for the type of material stored, which will be dry waste that is non-flammable, non-biodegradable and non-radioactive. In addition to the extraction of rock salt by underground mining, large quantities of salt are also produced by controlled solution mining. Production is now confined to Cheshire, where controlled solution mining is undertaken by two companies, Ineos Chlor Ltd and British Salt Ltd. Ineos Chlor supplies brine from the Holford brinefield for its own plant at Runcorn for the production of chlorine and caustic soda by the electrochemical process. The company also supplies brine to two plants operated by Brunner Mond in Northwich for the production of soda ash by the ammonia-soda process. Ineos has recently acquired Salt Union’s vacuum (white) salt operations at Runcorn, which also uses brine from Holford. British Salt Ltd also produces brine from the Warmingham brinefield in Cheshire for the production of white salt at its plant near Middlewich. British Salt is a wholly-owned subsidiary of US Salt Holdings. New Cheshire Salt Works Ltd extracts natural brine at the Wincham brinefield, near Northwich for the production of small quantities of white salt. Total UK production of white (brine) salt is estimated to be about one million tonnes and salt-in-brine for use as a chemical feedstock, 2.8 million tonnes. At the Warmingham brinefield, specially created salt cavities have been produced for natural gas storage and a proposal by Scottish Power for gas storage at the Holford brinefield has recently been granted permission. A similar proposal has been made to create an underground natural gas storage facility to the east of the Wyre Estuary in the Preesall saltfield in Lancashire. Twenty cavities are being proposed by solution mining at depths of up to 350 m. Brine produced by creating new cavities will be discharged into the sea. Brine extraction ceased at the Preesall saltfield in 1993 because of the closure of the Hillhouse chlorine plant in Fleetwood. Portland Gas Ltd, a wholly owned subsidiary of Egdon Resources Plc, is planning to create a salt cavity for natural gas storage beneath the Isle of Portland in Dorset. united Kingdom summary 2000–2004 Commodity 2000 2001 2002 2003 2004 2000 2001 2002 2003 2004 88 Tonnes £ thousand salt Production Salt, rock (a) 1 700 000 1 900 000 1 500 000 1 700 000 2 000 000 Salt from brine (a) 1 100 000 1 100 000 1 000 000 1 000 000 1 000 000 Salt in brine (a) (b) 3 000 000 3 000 000 3 200 000 3 200 000 2 800 000 Imports (c) 201 400 (c) 234 900 306 488 217 009 219 437 ... ... 12 870 10 928 13 713 Exports 307 899 299 607 326 760 537 497 691 010 16 548 17 466 20 135 23 202 26 638 (a) BGS estimate.
