Class B
Permitted development	B.	The winning and working on land held or occupied with land used for the purposes of agriculture of any minerals reasonably necessary for agricultural purposes within the agricultural unit of which it forms part.
Development not permitted	B.1	Development is not permitted by Class B if any excavation is within 24 metres of the nearest part of a special road or within 24 metres of the middle of a trunk or a first or second-class road or 9 metres from the middle of other classes of road.
Conditions	B.2	Development is permitted by Class B subject to the conditions— (a) that no mineral extracted during the course of the operation shall be moved to any place outside the land from which it is extracted, except to land which is held or occupied with that land and is used for the purposes of agriculture; (b) the surface of the land shall be levelled and any topsoil replaced as the uppermost layer; (c) the land shall so far as practicable be restored to its former condition before the extraction took place.
Interpretation of Class B	B.3	For the purposes of Class B the expression “purposes of agriculture” includes fertilizing the land used for the purposes of agriculture, and the maintenance, improvement or alteration of any buildings, structures or works occupied or used for such purposes on land so used.

Development not permitted	C.1	Development is not permitted in Class C if— (a) it is required in connection with development for which a planning application is necessary under Part 3 of the 2011 Act; or (b) the land is within a site of archaeological interest.
Class D
Permitted development	D.	The carrying out on agricultural land comprised in an agricultural unit of works for the erection, extension or alteration of a building or structure for the purpose of— (a) the generation (including the co-generation) of energy from anaerobic digestion of biomass; or (b) the storing of digestate; including works for the installation, alteration or replacement of a flue forming part of the anaerobic digestion system.
Development not permitted	D.1	Development is not permitted by Class D if— (a) the development is on agricultural land less than 0.5 hectares in area; (b) it consists of or includes the erection, extension or alteration of a dwelling; (c) a building, structure or works not designed for the purposes of anaerobic digestion is provided on the land; (d) the nearest part of any building or structure so erected or extended is more than 75 metres from the nearest part of a group of principal farm buildings; (e) the nearest part of any building or structure so erected or extended is less than 75 metres from a dwellinghouse (other than a dwellinghouse of any person engaged in agricultural operations on that unit); (f) the ground area to be covered by any building or structure erected or any building or structure as extended or altered, would exceed 500 square metres, calculated as described in paragraph D.2(a); (g) the height of any part of the building, structure or works within 3 kilometres of the perimeter of an airport exceeds 3 metres, or 12 metres in any other case; (h) any part of the development is within 24 metres from the nearest part of a special road, or within 24 metres of the middle of a trunk or a first or second-class road or 9 metres from the middle of other classes of road; (i) the total capacity of the anaerobic digestion system exceeds— (i) 200 kilowatts in relation to the generation of electricity; and (ii) 285 kilowatts thermal in relation to the production of heat; (j) feedstock not produced on land within the agricultural unit is used in the anaerobic digestion system; (k) feedstock not produced on land within the agricultural unit is stored within that unit; (l) it would result in more than one anaerobic digestion system within the agricultural unit.
