The Environmental Protection (Prescribed Processes and Substances) Regulations 1991

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 or does not fall within paragraph (b) of Part B of this Section.

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 or non-ferrous metal alloy except where the process is related to a process falling within a description in paragraphs (a), (c) or (d) of Part B of this Section.

(d)

Any process other than a process described in paragraphs (b), (c) or (d) of Part B of this Section for making or melting any non-ferrous metal or non-ferrous metal alloy in a furnace, bath or other holding vessel if the furnace, bath or vessel employed has a designed holding capacity of 5 tonnes or more.

(e)

Any process for producing, melting or recovering by chemical means or by the use of heat any of the elements listed below or any alloy whatsoever, if the percentage by weight of any of those elements which the alloy, in molten form, contains exceeds the relevant percentage specified below, and the process may result in the release into the air of particulate matter or smoke which contains any of those clements—

antimony	1 %
arsenic	1%
beryllium	0.1 %
chromium	2%
lead when alloyed with copper	23%
lead when alloyed with any metal other than copper	2%
magnesium	10%
manganese, when alloyed with copper	15%
manganese when alloyed with any metal other than copper	4%
phosphorus	1%
platinum	1%
selenium	0.5%

(f)

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 those metals in aggregate.

(g)

Any manufacturing or repairing process involving the 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.

(h)

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 cable), if related to another process described in this Part of this Section.

(i)

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.

(j)

Any process otherwise falling within a description in paragraph (a), (b), (d), (e) or (f) of Part B of this Section if the carrying on the process by the person concerned at the location in question is likely to produce 1000 tonnes or more of special waste in any 12 month period.
