When this new Order becomes operative a total of 11,835
premises and 8,292 acres of the Borough will be included in Smoke
Control Areas.
Prior Approval of Furnaces—Section 3.
Ten applications for Prior Approval of new furnaces were
received during the year. These varied from small central heating
boilers to medium sized industrial plant. Of these, eight were
oil fired installations, one coal fired by means of an underfeed
stoker and one incinerator for the destruction of domestic waste.
The latter applicant was advised on an alternative method of refuse
disposal and agreed not to proceed with the installation of the
incinerator. The other nine applications were all given approval.
Advice was given in a number of other instances where new
furnaces were being considered.
Chimney Heights—Section 10.
Approval of plans, where new chimneys were proposed, were
sought from fourteen applicants in accordance with Section 10 of
the act relating to the minimum height of chimneys. In five
instances the proposed height as shown on the plan was deemed to
be sufficient. On the basis of fuel consumption, etc., the other
nine chimneys planned were of insufficient height and were required
to be raised considerably. In one instance a height of 32 feet was
proposed against a requisite 60 feet. Another had to be raised
to 104 feet from a proposed 71 feet.
Offences.
There was one successful prosecution for a contravention of
the Act relating to business premises situated in a Smoke Control
Area. Smoke was seen to be emitted from a chimney on the premises
which on investigation was seen to be produced from coal.
A fine of £5, and £l, 1s. costs were imposed on the occupier by the
magistrates.
National Survey of Pollution.
Estimations of daily smoke and sulphur dioxide concentrations
were continued at the four sites in the Borough throughout the year
