20. Chemical Incineration Works
21. Hydrochloric Acid Works
22. Hydrogen Cyanide Works
23. Sulphide Works
Description
Works in which installed capacity exceeds 100 kg per hour and are used for the destruction by burning of wastes produced in the course of organic chemical reactions which occur during the manufacture of materials for the fabrication of plastics and fibres, and works for the destruction by burning of chemical wastes containing combined chlorine, fluorine, nitrogen, phosphorus or sulphur.
Works of the following kinds in which the installed capacity exceeds 1,000 tonnes per annum:
(a) hydrochloric acid works or works where hydrochloric acid gas is evolved either during the preparation of liquid hydrochloric acid or for use in any manufacturing process or as the result of the use of chlorides in a chemical process;
(b) tinplate flux works, works in which any residue or flux from tinplate works is calcined for the utilization of such residue or flux, and in which hydrochloric acid gas is evolved; or
(c) salt works (not being works in which salt is produced by refining rock salt, otherwise than by the dissolution of rock salt at the place of deposit) in which the extraction of salt from brine is carried on, and in which hydrochloric acid gas is evolved.
Works in which the installed capacity exceeds 1,000 tonnes per annum and in which hydrogen cyanide is made or is used in any chemical manufacturing process.
Works in which the processing capacity exceeds 1,000 tonnes (expressed as sulphuretted hydrogen) per annum and in which sulphuretted hydrogen is evolved by the decomposition of metallic sulphides, or in which sulphuretted hydrogen is used in production of such sulphides, or any works in which sulphuretted hydrogen is evolved as part of a chemical process not being a chemical process described in any other specified process.

TERMS AND CONDITIONS SUBJECT TO WHICH A LICENCE MAY BE GRANTED OR AN EXEMPTION CONTINUED
1. The place and times or periods at or during which the emission of air pollutants may take place.
2. The design and construction of any chimney or relevant plant or equipment used in connexion with the emission of any air pollutant.
3. The rate of discharge of any air pollutant or total amount thereof in relation to the matter discharged or any constituent thereof.
4. The nature, composition, colour or temperature of the matter discharged or any constituent thereof.
5. The treatment of any potential air pollutant before it is discharged and the chimney or relevant plant or equipment to be provided, maintained and used therefor.
