In the United Kingdom, CEMEX was originally fined £400,000 in October 2006 after hazardous dust was deposited up to three miles (5 km) away from its Rugby works. The fine was the highest ever given under the Integrated Pollution Prevention and Control regulations, and was also the highest for an Environment Agency prosecution for six years. The fine was, however, judged excessive by the Court of Appeal and so reduced to £50,000. In April 2007, CEMEX announced that it had installed a £6.5 million dust abatement system at the same works in Rugby, which had cut particulate emissions by 80%. The site comes under the auspices of the EU Waste Incineration Directive as it burns waste tyres for fuel. There are concerns over the impact on both the environment and human health from this practice, although it is common practice in many cement works.
