The dust fell on properties up to two miles away from the Rugby Cement plant in March 2007. Cemex UK admitted a charge of breaking its permit conditions in a case brought by the Environment Agency. It apologised for the incident which involved dust escaping from a silo.
The Environment Agency said it received nearly 100 complaints when the incident happened. Cemex was fined £20,000 and ordered to pay UK£13, 500 in costs. In a statement a spokesman said the dust was unlikely to have caused anyone any harm but apologised for the inconvenience caused.
