working of their oil burning muffle furnaces and have
carried out certain modifications to reduce the emission
of smoke into the atmosphere other modifications are, I
understand being considered. Also grit arrestors have
been fitted to the cupola stacks in the foundry- At the
present time works are in progress which should be completed
during 1957 on the construction of entirely new
types of cupola stacks which are stated to incorporate
much improved grit arresting appliances
It would appear that many of the difficulties experienced
in this area by residents can be attributed to the
absence of effective Town Planning legislation in the
past which allowed the siting of residential properties
in close proximity to a factory which is carrying out
heavy industrial processes,
Towards the end of the year the Council obtained the
advice of the Department of Scientific and Industrial
Research as to the siting of the atmospheric deposit gauge
and acting on this advice the Council authorised one
deposit gauge and a lead peroxide instrument to be erected
in the Greenford Green area and one deposit gauge and a
lead, peroxide instrument in the neighbourhood of the Town
Hall Ealing. These were placed in position in November
1956 and the readings for November and December were as
follows

The Clean Air Act 1956 came into operation on the
31st December, 1956 and I hope to be in a position to
include information on the administration of this Act in
Ealing in my next year s report.
During the year 185 smoke observations were made on
industrial premises in the Borough and in 3 cases it was
necessary for the Inspector to make representations to
the factories concerned regarding the emission of smoke.
In each case the necessary work was carried out and the
nuisances were satisfactorily abated.
