The Industrial Pollution Control (Prescribed Processes and Substances) Regulations (Northern Ireland) 1998

Part A

(a)

The extraction or recovery from any material—

(i)

by chemical means or the use of heat of any non-ferrous metal or alloy of non-ferrous metal or any compound of a non-ferrous metal; or

(ii)

by electrolytic means, of aluminium,

if the process may result in the release into the air of particulate matter or any metal, metalloid or any metal or metalloid compound or in the release into water of a substance described in Schedule 5 and is not a process for the separation of copper, aluminium, magnesium or zinc from mixed scrap by differential melting.

In this paragraph “material” includes ores, scrap and other waste.

(b) The mining of zinc or tin where the process may result in the release into water of cadmium or any compound of cadmium.

(c) The refining of any non-ferrous metal (other than the electrolytic refining of copper) or non-ferrous metal alloy except where the process is related to a process falling within one or more of the following descriptions—

(i) the making or melting of any non-ferrous metal or non-ferrous metal alloy where the designed holding capacity of molten metal is less than 5 tonnes;

(ii) melting zinc or a zinc alloy in conjunction with a galvanising process; or

(iii) melting zinc, aluminium or magnesium or an alloy of one or more of these metals in conjunction with a die casting process.

(d) Any process, for making or melting any non-ferrous metal or non-ferrous metal alloy where the designed holding capacity of molten metal is 5 tonnes or more other than any of the following processes—

(i) melting zinc, aluminium or magnesium or any alloy of one or more of these metals in conjunction with a die casting process;

(ii) melting zinc or a zinc alloy in conjunction with a galvanising process; or

(iii) the separation of copper, aluminium, magnesium or zinc from mixed scrap by differential melting.

(e) Any process for producing, melting or recovering by chemical means or by the use of heat, lead or any lead alloy, if—

(i) the process may result in the release into the air of particulate matter or smoke which contains lead; and

(ii) in the case of lead alloy, the percentage by weight of lead in the alloy in molten form exceeds 23 per cent. if the alloy contains copper and 2 per cent. in other cases.

(f) Any process for recovering any of the elements listed below if the process may result in the release into the air of particulate matter or smoke which contains any of those elements—

• gallium

• indium

• palladium

• tellurium

• thallium.

(g) Any process for producing, melting or recovering (whether by chemical means or by electrolysis or by the use of heat) cadmium or mercury or any alloy containing more than 0.05 per cent. by weight of either of those metals or of both of those metals in aggregate.

(h) Any manufacturing or repairing process involving the manufacture or use of beryllium or selenium or an alloy of one or both of those metals if the process may occasion the release into the air of any substance described in Schedule 4; but a process does not fall within this paragraph by reason solely of its involving the melting of an alloy of beryllium if that alloy contains less than 0.1 per cent by weight of beryllium in molten form and the process falls within one or more of the following descriptions—

(i) the making or melting of any non-ferrous metal or non-ferrous metal alloy where the designed holding capacity of molten metal is less than 5 tonnes; or

(ii) the melting of zinc, aluminium or magnesium or an alloy of one or more of these metals in conjunction with a die casting process.

(i) The heating in a furnace or other appliance of any non-ferrous metal or non-ferrous metal alloy for the purpose of removing grease, oil or any other non-metallic contaminant (including such operations as the removal by heat of plastic or rubber covering from scrap cable), if related to another process described in this Part of this Section.

(j) Any foundry process (including ancillary foundry operations such as the manufacture and recovery of moulds, the reclamation of sand, fettling, grinding and shot-blasting) if related to another process described in this Part of this Section.

(k) Pelletising, calcining, roasting or sintering any non-ferrous metal ore or any mixture of such ore and other materials.
