§ Mr. John Morrisasked the Secretary of State for Wales what details he has of the atmospheric pollution at Port Talbot; what is the authorised level; and whether he is satisfied with the position.
§ Mr. Peter ThomasI have the seasonal averages based on monthly reports made by the local authority to Warren Springs Laboratory of the Department of Trade and Industry on levels of smoke, sulphur dioxide, grit and dust, together with the reports of my district alkali inspector. For many processes which give rise to atmospheric pollution, authorised levels of emission are not laid down but the best practicable means are required to render emissions harmless and inoffensive. Where authorised levels of emission have been laid down, the standards are being met in the Port Talbot area.
