PART 7Storage of Organic Manure

Storage of organic manure

31.  An occupier of a holding who stores any organic manure (other than slurry), or any bedding contaminated with any organic manure, must store it—

(a)in a vessel;

(b)in a covered building;

(c)on an impermeable surface; or

(d)in the case of solid manure that can be stacked in a free standing heap and that does not drain liquid from the material, on a temporary field site.

Temporary field sites

32.—(1) A temporary field site must not be—

(a)in a field liable to flooding or becoming waterlogged;

(b)within 50m of a spring, well or borehole or within 10m of surface water or a land drain (other than a sealed impermeable pipe);

(c)located in any single position for more than 12 consecutive months; or

(d)located in the same place as an earlier one constructed within the last two years.

(2) Solid poultry manure that does not have bedding mixed into it and is stored on a temporary field site must be covered with an impermeable material.

Further requirements applicable to temporary field sites from 1 January 2014

33.  Further to regulation 32, from 1 January 2014—

(a)topsoil must not be removed from the ground upon which a temporary field site is to be constructed;

(b)a temporary field site must not be located within 30m of a watercourse on land identified on the risk map as having an incline of greater than 12°; and

(c)the surface area of a temporary field site should be as small as reasonably practicable to minimise the leaching effect of rainfall.

Separation of slurry

34.  Separation of slurry into its solid and liquid fractions must either be carried out mechanically or on an impermeable surface where the liquid fraction drains into a suitable receptacle.

Storage capacity

35.—(1) An occupier of a holding who keeps any of the animals specified in Schedule 1 must provide sufficient storage for all slurry produced on the holding during the storage period, and all poultry manure produced in a yard or building on the holding during the storage period.

(2) The volume of the manure produced by the animals on the holding must be calculated in accordance with Schedule 1.

(3) A slurry store must have the capacity to store, in addition to the manure, any rainfall, washings or other liquid that enters the vessel (either directly or indirectly) during the storage period.

(4) Storage facilities are not necessary for slurry or poultry manure—

(a)sent off the holding; or

(b)spread on land that has a low run-off risk (provided that this is done in accordance with the restrictions on spreading in these Regulations); but in this case storage facilities for an additional one week’s manure must be provided as a contingency measure in the event of spreading not being possible on some dates.

(5) For the purposes of this regulation the “storage period” (“cyfnod storio”) (all dates inclusive) is—

(a)the period between 1 October and 1 April for pigs and poultry;

(b)the period between 1 October and 1 March in any other case.
