§ Mr. Maclean
The main polluting industries are controlled under part I of the Environmental Protection Act 1990, the Health and Safety at Work etc. Act 1974 and the Alkali etc. Works Regulation Act 1906. The emphasis is on operators of these industries monitoring their own emissions. The relevant enforcing authorities have powers to check that this monitoring is undertaken satisfactorily and to carry out their own monitoring in order to substantiate the operator's results or to investigate matters not covered by the operator's monitoring programme.
