Exemption of Premises engaged in Investigation and Research.
Section 21 of the Clean Air Act, 1956, provides for firms engaged
in research with regard to air pollution and the efficiency of furnaces
generally to apply for exemption in the event of emission of smoke
above the prescribed density.
One application for exemption under this Section was received,
and this was granted for one year. No untoward emissions were
observed.
