Kennel to challenge T5 over construction dust

NEWS

CONSTRUCTION OF Heathrow airport's £2.5bn Terminal 5 was this week under threat as a local quarantine kennel announced that it was seeking an Appeal Court ruling to quash planning permission.

Willowslea Farm Kennels' appeal will be heard in the next three months.

Its argument against the £2.5bn scheme is centred on the air pollution expected from construction activity that will soon surround its buildings.

Problems will be compounded, it says, by a lorry park to be built on green belt land on the other side of the kennels also as part of the T5 project.

'We are concerned that the measures planned to monitor air pollution will not be effectively managed and do not include very fine dust particles, ' said John Tenconi, an independent business consultant acting on behalf of the kennels.

This type of dust, PM2.5, has particle matter with a diameter of less 0.0025mm for which there is currently no legal limit, unlike the larger and commonly monitored PM10.

But the kennel claims that the smaller particles are potentially more damaging.

World Health Organisation Guidelines for Air Quality 2000.

states that 'particle size is a critical factor in internal dose distribution'. This means that the smaller the particle size the more likely it is to reach the lower respiratory tract - where it can cause most harm.

A T5 spokesman said: ' Monitoring PM2.5 is not a problem should we have to do it.' But he added that it would be crucial to set the right benchmark level and find the best method of setting this level.
