17.—(1) Subject to paragraphs (2) and (3) and regulations 18 to 24, the capacity of storage facilities for livestock manure and silage effluent of a holding shall be sufficient and adequate to provide for the storage of all the livestock manure and silage effluent which is likely to require storage on the holding for such period as may be necessary to ensure compliance with these Regulations and the avoidance of water pollution.
(2) For the purposes of paragraph (1), the controller shall have due regard to the storage capacity likely to be needed by the holding during periods of adverse weather conditions when, due to extended period of wet weather, frozen ground or otherwise, the application to land of organic manure is not permitted.
(3) Subject to regulation 18, the total livestock manure storage capacity on holdings shall be sufficient for at least 22 weeks storage.
(4) All storage facilities for livestock manure and silage effluent shall be maintained free of structural defect, shall be of such standard as is necessary and be managed to prevent run-off or seepage, directly or indirectly, into a waterway or water contained in any underground strata and where applicable shall comply with regulations 19 and 24.

(3) On any holding where there is—
(a)a pig enterprise;
(b)a poultry enterprise; or
(c)both a pig and poultry enterprise,
(4) in addition to another livestock enterprise the livestock manure storage capacity on the holding shall be sufficient for at least 26 weeks storage for the pig or poultry enterprise and at least 22 weeks for the other livestock enterprise.
19.—(1) Subject to paragraph (2), an appropriate person having custody or control of slurry shall store it in a slurry storage system in relation to which the requirements of Schedule 6 are satisfied or which is an exempt structure by virtue of paragraph (3).
(2) Paragraph (1) shall not apply to slurry while it is stored temporarily in a tanker with a capacity not exceeding 18,000 litres which is used for transporting slurry on roads or about a holding.
(3) A slurry storage system is an exempt structure if—

23.—(1) In calculating the livestock manure storage capacity of a holding, the following farming practices may be taken into account—
(a)the quantity of farmyard manure stored in a midden or field prior to land application in accordance with regulation 20;
(b)any solids removed from slurry other than pig slurry by means of a slurry separator;
(c)any additional storage available off the holding, by means of a rental agreement;
(d)any valid contract the controller has with a manure processing facility or demonstrable access to an approved treatment or recovery outlet; and
(e)the quantity of poultry litter or anaerobic digestate fibre stored in a midden or field prior to land application in accordance with regulation 21.
(2) Subject to paragraph (4), the livestock manure storage capacity of a holding may be less than the capacity specified in regulation 17 in relation to—
(a)sheep, deer and goats which are out-wintered at a grassland stocking rate which does not exceed 130 kg of nitrogen at any time during the period specified in regulation 7(3) in relation to the application of organic manure as calculated in accordance with paragraph (6);
(b)livestock (other than dairy cows, sheep, deer and goats) which are out-wintered at a grassland stocking rate which does not exceed 85 kg of nitrogen at any time during the period specified in regulation 7(3) in relation to the application of organic manure, as calculated in accordance with paragraph (6), provided the amount of livestock manure produced on the holding does not exceed 140 kg of nitrogen per hectare per year, as calculated in accordance with regulation 9; and
(c)a mixed holding the nitrogen limit in sub-paragraph (b) shall apply except where the controller of the holding demonstrates to the Department that the livestock out-wintered more appropriately reflects the composition of the livestock applicable in sub-paragraph (a).
(3) The livestock manure storage capacity of a holding shall be calculated in accordance with—
(a)the livestock manure production figures specified in Table 6 of Schedule 2; and
(b)any further procedures for calculating such storage capacity which may be specified in any guidance issued in accordance with regulation 5.
(4) A holding falling with paragraph (2) must ensure that—
(a)out-wintered livestock have free access at all times to the land area required for the relevant stocking rate;
(b)land is maintained in good agricultural and environmental condition; and
(c)the reduction in storage capacity is proportionate to the extent of out-wintered livestock on the holding.
(5) Any land used for the purpose of out-wintering under paragraphs (2) and (4) must be under the control of the controller of the holding to which the exemption applies.
(6) In this regulation, a grassland stocking rate of 130 kg or 85 kg of nitrogen, as the case may be, means the stocking of grassland on a holding at any time by such numbers and types of livestock as would in the course of a year excrete waste products containing 130 kg or 85 kg nitrogen, as the case may be, per hectare of the grassland when calculated in accordance with the nitrogen excretion rate of livestock specified in Table 1a of Schedule 2.
(7) In this regulation, mixed holding means a holding where there are sheep, deer, goats or other livestock (other than dairy cows).
24.—(1) Subject to paragraph (3), an appropriate person shall not have custody or control of any crop which is being made into silage, or of any silage, which is being stored unless—
(a)it is kept in a silo in relation to which the requirements of Schedule 7 are satisfied or which is an exempt structure by virtue of paragraph (3);
(b)it is compressed in the form of bales which are wrapped and sealed within impermeable membranes (or are enclosed in impermeable bags) and are stored at least 10 metres from any waterway that effluent escaping from the bales could enter; or
(c)it is made as bulk bagged silage in bags which—
(i)are made of 1000 gauge polyethylene or material of at least equivalent impermeablility and durability;
(ii)are kept sealed to prevent the escape of silage effluent;
(iii)incorporate a facility designed to enable the safe removal of excess effluent when present; and
(d)are stored at a place at least 10 metres from any waterway that effluent escaping from the bales could enter.
(2) Any appropriate person having custody or control of any crop which is being made, or has been made, into silage in the manner described in paragraph (1)(b) or (c) shall not open or remove the wrapping of any bales or open or empty any bulk bags within 10 metres of any waterway that effluent escaping from the bales or bulk bags could enter.
(3) A silo is for the time being an exempt structure if—
(a)its construction for the purpose of making and storing silage was completed before 1st December 2003; and
(b)it has not ceased to be an exempt structure by virtue of paragraph (4).
(4) A structure to which the circumstances set out at paragraph (3) apply shall cease to be an exempt structure if—
(a)any requirement of a notice under regulation 30(1) is not complied with within the period stated in the notice; or
(b)it is substantially enlarged; or
(c)it is substantially reconstructed, unless, it appears to the Department, the risks of pollution will be reduced by such works.
(5) Any reference in paragraph (4) to the period stated in a notice is to that period as extended if it has been extended under regulation 30(5) and any reference in that paragraph to a requirement of a notice is to that requirement as modified if it has been modified under regulation 30(5).
(6) Any appropriate person who proposes to have custody or control of any crop which is being made into silage, or of any silage, which is to be kept or stored on a holding in a silo constructed, substantially enlarged or substantially reconstructed on or after 1st December 2003 shall serve notice on the Department specifying the type of structure to be used and its location at least 28 days before it is to be first used for such purpose.
25. After harvesting a crop other than grass the controller shall ensure that from the date of harvesting to 15th January in the following year, one of the following conditions is met on the land at any time—
(a)the stubble of the harvested crop remains in the land;
(b)the land is sown with a crop which will take up nitrogen from the soil; or
(c)where soil or weather conditions prevent a subsequent crop from being sown, appropriate measures are put in place to limit soil erosion.
