"Harm" means harm to the health of living organisms or other interference with the ecological systems of which they form part and, in the case of man, includes offence caused to any of his senses or harm to his property; and "harmless" has a corresponding meaning.

"Process" means any activities carried on in Great Britain, whether on premises or by means of mobile plant, which are capable of causing pollution of the environment and "prescribed process" means a process prescribed under section 2(1) below.

For the purposes of subsection (5) above—

"activities" means industrial or commercial activities or activities of any other nature whatsoever (including, with or without other activities, the keeping of a substance);
"Great Britain" includes so much of the adjacent territorial sea as is, or is treated as, relevant territorial waters for the purposes of [Part III of the Water Resources Act 1991] or, as respects Scotland, Part II of the Control of Pollution Act 1974; and
"mobile plant" means plant which is designed to move or to be moved whether on roads or otherwise.

The "enforcing authority", in relation to England and Wales, is the Environment Agency or the local authority by which, under section 4 below, the functions conferred or imposed by this Part otherwise than on the Secretary of State are for the time being exercisable in relation respectively to releases of substances into the environment or into the air; and "local enforcing authority" means any such local authority.

In relation to Scotland, references to the "enforcing authority" and a "local enforcing authority" are references to the Scottish Environment Protection Agency (in this Part referred to as "SEPA").

"Authorisation" means an authorisation for a process (whether on premises or by means of mobile plant) granted under section 6 below; and a reference to the conditions of an authorisation is a reference to the conditions subject to which at any time the authorisation has effect.

A substance is "released" into any environmental medium whenever it is released directly into that medium whether it is released into it within or outside Great Britain and "release" includes—

in relation to air, any emission of the substance into the air;

in relation to water, any entry (including any discharge) of the substance into water;

in relation to land, any deposit, keeping or disposal of the substance in or on land;

and for this purpose "water" and "land" shall be construed in accordance with subsections (11) and (12) below.

For the purpose of determining into what medium a substance is released—

the sea or the surface of the seabed,

any river, watercourse, lake, loch or pond (whether natural or artificial or above or below ground) or reservoir or the surface of the riverbed or of other land supporting such waters, or

is a release into water;

any release into—

is a release into land; and

any release into a sewer (within the meaning of [the Water Industry Act 1991] or, in relation to Scotland, of the Sewerage (Scotland) Act 1968) shall be treated as a release into water;

but a sewer and its contents shall be disregarded in determining whether there is pollution of the environment at any time.
