The UK's largest supplier of ready-mixed concrete have been fined £110,000 at their site in Ealing for a string of environmental offences.
Hanson Concrete, who have operated from their site in Horn Lane, Acton, Ealing, for 50 years, were found guilty of five offences between May 2014 and April 2015.
Officers from Ealing Council found that permit conditions relating to dust emission, spillages, storage of waste and inadequate maintenance had not been met.
Hanson Quarry Products Europe Limited, trading as Hanson Concrete, was sentenced at Uxbridge Magistrates' Court on February 2.
The company was fined £110,000, ordered to pay the council's costs of £9,286 plus a victim surcharge of £120.
It has operated from the Horn Lane site for half a century, but in 2010 the old site was demolished, including a wheel washing facility.
The following year permission was given to re-open but the company was issued with an environmental permit designed to cut pollution a limit the impact on Acton residents.
Conditions included no visible dust emitted from the site, spillages to be cleaned immediately, no waste spilled in the local area and that lorry wheels are cleaned before they leave the site.
Officers visited the site in 2013 after they measured an increase in air pollution and residents had started to complain.
The company also breached an enforcement notice in April 2015 that required it to clean lorry wheels.
Councillor Julian Bell , leader of the council, said: “This judgement is a great result for local people and for our officers.
"It sends out a clear message that Ealing Council takes any environmental breaches very seriously and we will pursue companies that fail to operate responsibly.
"Horn Lane is a residential area and all of the companies around there, including Hanson Concrete, have a duty towards the families that live nearby.
"Hanson Concrete pleaded guilty to these charges, but if they had taken appropriate measures in the first instance they would have avoided this action and improved air quality for local people sooner."
The company has now made a number of changes to the site, including new wheel washing equipment and additional pollution moniter.
They were found guilty of:
Contravention of permit condition 6 (immediate cleaning up of spillages) - fine of £16,000
Two contraventions of permit condition 8 (no spillage into areas surrounding designated waste areas) - fines of £16,000 each = £32,000
Dust emitted from the yard surface by a moving vehicle, in contravention of permit condition 3 - fine of £16,000
Contravention of an enforcement notice on wheel cleaning - fine of £46,600
