		DUAP Condition 73/4 Protocol This document has been developed to establish a protocol outlining the procedure for deciding how an exceedance due to the M5 East Motorway Ventilation Stack is determined. M5 East air quality data Due to technical difficulties, some air quality monitoring data from the period 2-3 July 2004 and 17-18 July 2004 was unable to be forwarded to the website within the specified data collection time window. The website displayed no values at times, however the raw air quality monitoring data was continuously logged and it is now available for viewing.
