[holding answer 27 February 2009]: Emerging results of air quality modelling were delivered over a period of time and reported to the Department's Heathrow Project Board. It was already clear by July 2007 that the air quality limits were likely to be met in the third runway scenarios. Final results, including for the mixed mode scenarios, were reflected in successive drafts of the consultation document reviewed by the board up to its conclusion in October 2007.
