§ Mr. Harold Walkerasked the Secretary of State for the Environment (1) how frequently checks are made on the sulphur dioxide levels at Bessacarr, Doncaster; at what hours of the day or night these checks are made; and how the peak periods of pollution compare with the peaks prior to the establishment of the Coalite plant;
(2) what are the arrangements for monitoring pollution of the air in the vicinity of the Coalite plant at Rossington, Doncaster.
§ Mr. Eldon GriffithsContinuous measurements are being made of smoke and sulphur dioxide at several sites within a two-mile radius of the works including one at Bessacarr. These monitor the average emissions of these pollutants over each 24-hour period but it is as yet too early for meaningful comparisons to be drawn between the situation before and that since the plant started working.
