To ask the Secretary of State for Scotland, pursuant to his answer of 19 May, Official Report, column 218, what prosecutions have been undertaken resulting from breach of the prescribed process regulations since 31 July 1992.

[holding answer 14 June 1993]: The results of a survey on the operation of local authority air pollution control in Scotland during its first year (1 April 1992 to 31 March 1993) are currently being analysed. From 54 returns so far received from the 56 district and islands councils, the survey indicates that no prosecutions were undertaken during that period.
