§ Mr. Levitt
To ask the Chancellor of the Exchequer what assessment he has made of the effect of the aggregates levy on(a) companies in the extraction industries, (b) the environment in the vicinity of quarries and (c) the quantity of recycled building materials being used. 
§ John Healey
The aggregates levy has only been operational since 1 April 2002. Although Customs and Excise, who have responsibility for administering the levy, are monitoring its economic and environmental impacts, it is too early for an assessment to be made. Customs' monitoring takes account of data from specific research as well as information from business organisations, individual companies and environmental organisations.
