Section 4.5 Inorganic chemical processes

Part A

(a) The manufacture of hydrogen cyanide or hydrogen sulphide other than in the course of fumigation.

(b) Any manufacturing process involving the use of hydrogen cyanide or hydrogen sulphide.

(c) Any process for the manufacture of a chemical which may result in the release into the air of hydrogen cyanide or hydrogen sulphide.

(d) The production of any compound containing any of the following—

• antimony

• arsenic

• beryllium

• gallium

• indium

• lead

• palladium

• platinum

• selenium

• tellurium

• thallium

• titanium

• vanadium

where the process may result in the release into the air of any of those elements or compounds or the release into water of any substance listed in Schedule 5 in a quantity which in any 12 month period exceeds the background quantity by more than the amount specified in relation to the description of the substance in column 2 of Schedule 5.

(e) The recovery of any compound referred to in paragraph (d) where the process may result in any such release as is mentioned in that paragraph.

(f) The use in any process of manufacture, (other than the application of a glaze or vitreous enamel), of any element or compound referred to in paragraph (d) where the process may result in such a release as is mentioned in that paragraph.

(g) The production or recovery of any compound of cadmium or mercury.

(h) Any process of manufacture which involves the use of cadmium or mercury or of any compound of either of those elements or which may result in the release into the air of either of those elements or any of their compounds.

(i) The production of any compound of—

• chromium

• manganese

• nickel

• zinc.

(j) The manufacture of any metal carbonyl.

(k) Any process for the manufacture of a chemical involving the use of a metal carbonyl.

(l) The manufacture or recovery of ammonia.

(m) Any process for the manufacture of a chemical which involves the use of ammonia or may result in the release of ammonia into the air other than a process in which ammonia is used only as a refrigerant.

(n) The production of phosphorus or of any oxide, hydride or halide of phosphorus.

(o) Any process for the manufacture of a chemical which involves the use of phosphorus or any oxide, hydride or halide of phosphorus or which may result in the release into the air of phosphorus or of any such oxide, hydride or halide.

(p) The extraction of any magnesium compound from sea water.

Part B

The manufacture of inorganic chemicals not described elsewhere in this Schedule.
