What specific actions, if any, are you taking to ensure that the PM10 daily limit value is met in 2011 at each of the Bexley (Erith); Ealing (Horn Lane); Brent (Neasden Lane) monitoring sites, despite these monitoring sites not being used by Defra to report compliance with PM10 limit values nationally to the EU?

Answer for Air quality monitoring sites (2)

Answered By: 
The Mayor

The monitoring sites at Bexley (Erith), Ealing (Horn Lane) and Brent (Neasden Lane) are all located close to waste management sites where resuspension of particles from vehicles or processes on site can cause high levels of particulate matter (PM). Although regulation of air quality at waste sites in London is a shared responsibility of the Environment Agency and the boroughs, not the GLA, I am aware of the high levels of PM at these locations and my Environment Advisor has discussed this matter at a senior level with the Agency.

Although air quality at these sites has improved over recent years due to the efforts of the Environment Agency and boroughs, more can and should be done. The GLA and boroughs are part of a working group which is chaired by the Environment Agency. The work of this group has resulted in operational improvements at a number of sites, including the installation of wheel washing facilities, moving operations inside buildings, installing water spray systems to damp down sites, regular road sweeping on and off the public highway, operator self-monitoring and even changing the types of waste accepted at the sites. We will continue to work with the Environment Agency and boroughs to improve mitigation measures further.
