During 1958, 11 notifications were received concerning the proposed discharge of
trade effluents. In 7 cases notices of proposed conditions were issued by this Council
and in none of these cases were counter proposals received. In one case the effluent
was such as not to warrant a notice. In the remaining three cases, the premises concerned
were connected to the London County Council's sewers, and the notifications
were dealt with by that authority.
Clean Air Act, 1956
During the year 38 complaints were received regarding smoke emissions and 374
observations were made. In most cases, it was found that the nuisance was caused by
unsatisfactory stoking, and conditions were remedied following advice being given by the
District Public Health Inspectors.
The routine of making special observations from the roofs of four tall buildings was
continued, and as in previous years these observations were helpful in checking the
behaviour of boiler plant, especially in connection with plant installed in the many new
buildings which have been erected. Most of the new installations however, are oil fired
and consequently little trouble from smoke is experienced.
Measurement of Deposited Matter and Sulphur Dioxide
Since 1953 these forms of pollution have been recorded each month by means of
apparatus installed on the roof of the British Museum. The apparatus consists of a
deposit gauge for collecting rainwater and deposited matter, and a lead peroxide instrument
for recording the amount of sulphur dioxide in the atmosphere.
