§ Mr. Randall
To ask the Secretary of State for Transport what steps his Department will take to instigate levels of nitrogen dioxide consistently within EU limits by 2010 at Heathrow Airport. 
§ Mr. McNulty
Heathrow Airport lies within an Air Quality Management Area declared by adjacent local authorities. Various emissions sources may contribute to potential NO2 exceedances in 2010. In the vicinity of Heathrow Airport mitigation strategies could apply to aircraft, airside and road traffic sources, although general 'background' levels of NO2 are also a major contributor (as elsewhere). BAA plc is required to produce and review an Action Plan to minimise emissions from Heathrow Airport as a condition of the planning permission for the Fifth Terminal.
