8.—(1) In this Part—
“agricultural diffuse pollution” means the transportation of the agriculture target substances into the water environment where the transportation occurs by means of soil erosion, runoff or leaching;
“agricultural land” means land used for agriculture for the purposes of a trade or business;
“agriculture” includes—
horticulture, fruit growing, seed growing, dairy farming, livestock breeding and keeping,
the use of land as grazing land, meadow land, osier land, market gardens and nursery grounds, and

“groundwater” means all water which is below the surface of the ground in the saturation zone and in direct contact with the ground or subsoil;
“leaching” means the process by which the agriculture target substances are washed or drained from soil into the water environment by rainwater or other liquid applied to agricultural land;
“poaching” means the trampling or treading of agricultural land by livestock resulting in a layer of compacted soil with overlying mud;
“runoff” means the transportation into the water environment of rainwater or other water running over agricultural land;
“soil erosion” means soil loss caused by—
runoff or degradation over a single area of agricultural land (whether or not crossing permanent boundary features) of at least 1 hectare, or
poaching adjacent to freshwaters or coastal waters over a single stretch of agricultural land (whether or not crossing permanent boundary features) which is at least 2 metres wide and 20 metres long;
“the water environment” means—
freshwaters and groundwater in England, and
coastal waters adjacent to England.
(2) In the definition of the water environment in paragraph (1), coastal waters adjacent to England are such coastal waters adjacent to Great Britain as do not form part of—
(a)the sea adjacent to Scotland, or
(b)Wales.
(3) In paragraph (2)—
(a)the sea adjacent to Scotland has the same meaning as the internal waters and territorial sea of the United Kingdom adjacent to Scotland has by virtue of section 126(2) of the Scotland Act 1998(1);
(b)Wales has the meaning given by section 158 of the Government of Wales Act 2006(2).
1998 c. 46. The boundaries between waters which are to be treated as internal waters or territorial sea of the United Kingdom adjacent to Scotland and those which are not are set out in S.I. 1999/1126.
2006 c. 32. Section 158(1) defines “Wales” as including the sea adjacent to Wales out as far as the seaward boundary of the territorial sea. Section 158(3) makes provision for the determination of any boundary between waters which are to be treated as parts of the sea adjacent to Wales and those which are not. The boundary between the sea adjacent to Wales and that adjacent to England is partly determined by article 6 of, and Schedule 3 to, S.I. 1999/672. By virtue of paragraph 26 of Schedule 11 to the Government of Wales Act 2006, S.I. 1999/672 continues to have effect.
