The following table illustrates this SO2 problem. Given are the daily average figures
which are so far available over recent years. These figures relate to the three stations
monitoring air pollution levels at Barnes, Hampton and Whitton and operated by this
Department. Two other stations in Teddinszton and Kew are ooerated bv the Denartment
of the Environment.
of the Environment. It will be seen that whilst the concentration of smoke continues to
lessen, the levels of SO2 are on the increase.

During the year two Exemption Orders were made in respect of coal burning
domestic appliances. The Smoke Control Areas (Exempted Fireplaces) Order, 1972
permits the installation, on conditions, of the Parkway Coalmaster, and the Smoke Control
Areas (Exempted Fireplaces) (No. 2) Order, 1972 permits, on conditions, the
installation of the Trianco TGB17.
The coal miner's strike in February created difficulties for the fuel merchants but
they managed to supply all who were in need and there was never any need to suspend
smoke control orders.
Six applications were made for approval of proposed chimney heights as required by
Section 6 of the Clean Air Act, 1968. One was refused because the height was inadequate
having regard to the amount of SO2 which it was intended to discharge from the chimney.
Two occupiers of buildings in smoke control areas were found to be emitting smoke
from fuels other than those authorised. Both complied with the Acts upon an informal
request.
In all 86 complaints were received concerning smoke emissions, approximately a
30% reduction on last year. All nuisances were abated on an informal approach. The
fact that no prosecutions were necessary indicates the strength of public support for a
cleaner environment.
