The filtration and chlorination equipment at the Borough Council's swimming baths is highly efficient and the
analyses generally give very good results. The Baths Department is advised of the results of the tests in respect of
the Council Controlled establishments and these results are supplementary to the tests undertaken by the staff of
that Department.
Chimney Heights
Nine applications were received under Section 6 of the Clean Air Act 1968. In one instance the proposed height
was not acceptable and revised proposals were agreed after discussion with the engineers.
Of four cases not subject to specific control by Section 6 one chimney proposed was considered to be of
insufficient height and the plans were subsequently modified to the satisfaction of the department.
Furnace Installations
The use of natural gas at six industrial furnaces came to the notice of the Department during the year.
Control of Atmospheric Pollution
Of 96 half-hour observations of industrial chimneys made during the year 6 emissions of smoke were found to be
excessive and were halted following informal action. There were 4 contraventions arising from on-site burning
where buildings were being demolished. Excessive smoke arising from two incinerators was observed. One of these
was replaced by a modern appliance and in the other case, improved management of the appliances prevented
the continuance of the nuisance.
Smoke Control Orders
In two cases it was found that householders in contravention of smoke control orders were causing the emission
of smoke by burning bituminous coal which they had purchased locally and in third case a householder was
found to be burning wood road blocks. Suitable warnings were given and the offences were terminated.
Investigation of Atmospheric Pollution
Up to the end of the year under review Haringey maintained three daily recording instruments for the collection
of data regarding the smoke and sulphur dioxide content of the atmosphere. It was necessary to close down the
Burghley Road station at the end of 1972 because a change of use of the site necessitated the removal of the
measuring equipment. In addition to giving information on local trends, the data forms part of information
collected by the Warren Spring Laboratory to show national distribution and trends in atmospheric pollution. The
readings obtained depend to some extent on varying local meterorological conditions which at times may give
rise to deviations from the general trend.
