§ Mr. Hooleyasked the Minister of Housing and Local Government what is the estimated quantity of grit sulphur and other pollutants deposited over the surrounding area by a conventional coal-fired power station in the course of 12 months.
§ Mr. GreenwoodThe quantity of dust deposited within a radius of five miles of a typical coal-fired power station of 1,000 M.W. to. 2,000 M.W. capacity, equipped with modern dust arrestment plant and a suitable chimney or chimneys, is about 40 tons a year. Typical annual rates of dust deposition in areas of similar size remote from power stations are 4,000 tons in a wholly rural area and 18,000 tons in a wholly industrial area. Thus the power station adds only 0.2 per cent. to 1.0 per cent. to the dust fall in its locality.
There is no deposit of sulphur, but emissions of sulphur dioxide from modern power stations add very little to ground-level pollution in their vicinity. A recent long-term survey in an essentially rural
