OFFENSIVE TRADES
There is only one offensive trade business established in the
Borough, and during the year no complaints were received.
ATMOSPHERIC POLLUTION
CLEAN AIR ACT, 1956
THE SMOKE CONTROL AREAS (AUTHORISED FUELS)
REGULATIONS, 1956
The Clean Air Act, 1956 (Appointed Day) Order, 1956, brought
into operation on the thirty-first day of December, 1956, certain
provisions of the Clean Air Act, 1956, including provisions relating
to smoke from furnaces, smoke control areas, the extension of the
Alkali, etc., Works Regulations Act, 1906 to cover the emission of
smoke, grit and dust from premises controlled, or to be controlled,
under that Act, colliery spoilbanks and the constitution of the
Clean Air Council.
The Smoke Control Areas (Authorised Fuels) Regulations,
1956, also came into operation on the thirty-first day of December,
1956, and declared certain fuels to be authorised fuels for the
purpose of the Act, Section 11 of which makes it an offence to emit
smoke from any building in a smoke control area, unless it can be
shewn that the emission of smoke was not caused by the use of
any fuel other than an authorised fuel.
As the Act and Regulations only came into operation on the
last day of the year, there is, of course, nothing to report on its
implementation, although certain preparatory work and discussion
took place.
During the year another deposit gauge and lead peroxide instrument
were erected in a residential area some distance from
industry for comparison purposes with the other three sites, and
the results of the analyses taken at all four sites are appended.
Site No. 1 is at Carterhatch Road, Site No. 2 is at Bilton Way,
Site No. 3 is near the Royal Small Arms Factory, and site No. 4 is
at Bell Road, Baker Street.
The dissolved solids, suspended solids and total solids are
recorded in tons per square mile and, for comparative purposes only,
the sulphur dioxide in the atmosphere is expressed in milligrammes
of sulphur trioxide per day per 100 sq. cm. of lead peroxide exposed.
On an average throughout the year there is little difference
in the recordings at the four sites, the low figures for total solids
for February, March and November coinciding with the three
lowest monthly recordings of rainfall during the year. Comparisons
with a number of districts in Greater London, are in favour of
Enfield.
