(2) The occupier of a holding must ensure that the total amount of nitrogen in organic manure exclusively in the form of certified compost applied to any given hectare on the holding does not exceed—

(a)1000 kg in any four year period if it is applied as mulch to orchard land, or

(b)500 kg in any two year period if it is applied to any other land.

(3) For the purposes of paragraphs (1) and (2), the total amount of nitrogen in organic manure must be calculated by reference to the methods described in regulation 9 for establishing nitrogen content.

(4) In this regulation—

(a)“orchard land” means land on which any fruit listed in Schedule 2 is grown;

(b)“certified compost” means green compost or green/food compost in relation to which the supplier confirms in writing that it meets the standards set out in the publication PAS 100:2011 on composted materials dated January 2011 and contains no livestock manure;

(c)the occupier must retain written confirmation that the organic manure complies with sub-paragraph (b).

PART 3Crop requirements

Planning the spreading of nitrogen fertiliser

6.—(1) An occupier of a holding who intends to spread nitrogen fertiliser must—

(a)calculate the amount of nitrogen in the soil that is likely to be available for uptake by the crop during the growing season (“the soil nitrogen supply”),

(b)calculate the optimum amount of nitrogen that should be spread on the crop, taking into account the amount of nitrogen available from the soil nitrogen supply, and

(c)produce a plan for the spreading of nitrogen fertiliser for that growing season.

(2) In the case of any crop other than permanent grassland, the occupier must comply with paragraph (1) before spreading any nitrogen fertiliser for the first time for the purpose of fertilising a crop planted or intended to be planted.

(3) In the case of permanent grassland the occupier must comply with paragraph (1) each year beginning 1 January before the first spreading of nitrogen fertiliser.

(4) The plan must be in permanent form.

(5) The plan must record—

(a)the reference or name of the relevant field,

(b)the area of the field planted or intended to be planted, and

(c)the type of crop.

EXPLANATORY NOTE

(This note is not part of the Regulations)

These Regulations revoke and replace—

(a)the Nitrate Pollution Prevention (Wales) Regulations 2013 (S.I. 2013/2506 (W. 245)) which control the application of nitrogen fertiliser in nitrate sensitive areas, and

(b)the Water Resources (Control of Pollution) (Silage and Slurry) (Wales) Regulations 2010 (S.I. 2010/1493 (W. 136)) which regulate the custody and control of silage and slurry and provided the design and construction standards applicable for its storage.

These Regulations make provision concerning the protection of waters against pollution by nitrates from agricultural sources.

Principal Changes

Whereas the requirements under the Nitrate Pollution Prevention (Wales) Regulations 2013 applied only to holdings situated in designated Nitrate Vulnerable Zones, these requirements will now apply to all holdings in Wales. The majority of the measures in the Water Resources (Control of Pollution) (Silage and Slurry) (Wales) Regulations 2010 will continue to apply under these Regulations but the capacity requirements for the storage of organic manure and silage in those Regulations are superseded and mirror those in the Nitrate Pollution Prevention (Wales) Regulations 2013.

Furthermore, persons proposing to build or improve their storage facility for slurry or silage will be required to notify the Natural Resources Body for Wales (“NRBW”) 14 days before construction work is begun, replacing the previous requirement for notification prior to the storage facility’s actual use.

Occupiers of organic holdings wishing to benefit from the exemption to the closed periods for spreading organic manure with high readily available nitrogen (regulation 20) must now submit an undertaking to the control system referred to in Article 27 of Council Regulation (EC) 834/2007 rather than register with the Advisory Committee on Organic Standards which has now been dissolved.

The Regulations

Part 1 of these Regulations contains introductory provisions including transitional provision for all holdings not previously within a Nitrate Vulnerable Zone which are now required to comply with the relevant provisions and requirements under these Regulations.

Part 2 of these Regulations imposes annual limits on the amount of nitrogen from organic manure that may be applied or spread.

Part 3 establishes requirements relating to the amount of nitrogen to be spread on a crop, and requires an occupier to plan in advance how much nitrogen fertilizer will be spread.

Part 4 requires an occupier to provide a risk map of the holding, and imposes conditions on how, where and when to spread nitrogen fertilizer.

Part 5 establishes closed periods during which it is prohibited to spread nitrogen fertilizer.

Part 6 makes provision for the storage of organic manure and prescribes the capacity and construction requirements for such storage systems. It provides for exemptions from the requirements for certain storage systems; for NRBW to serve notices requiring the carrying out of works or precautions for reducing the risk of pollution to controlled waters and provides an appeal process against such notices. It also requires NRBW to be notified of certain works to be carried out to such storage systems.

Part 7 specifies what records must be kept.

Part 8 requires the Welsh Ministers to review these Regulations within set time scales, including a review after two years to consider any submissions on an alternative suite of measures to those in these Regulations for preventing or reducing pollution caused by agriculture.

Part 9 of these Regulations provides for enforcement and for contravention of certain regulations to be a criminal offence. These Regulations are enforced by NRBW.

Part 10 contains miscellaneous provisions including revocations.

These Regulations repeal and re-enact (without modification) technical regulations in the Water Resources (Control of Pollution) (Silage and Slurry) (Wales) Regulations 2010.

1991 c. 57. Section 92 was amended by the Environment Act 1995 (c. 25) section 120 and paragraph 128 and 144 of Schedule 22 to that Act, and by S.I. 2010/675 and S.I. 2013/755 (W. 90). There are amendments to section 219 which are not relevant to these Regulations. By virtue of article 2 of, and Schedule 1 to, the National Assembly for Wales (Transfer of Functions) Order 1999 (S.I. 1999/672) functions of the Secretary of State under section 92 were transferred to the National Assembly for Wales in relation to those parts of Wales which are outside the catchment areas of the rivers Dee, Wye and Severn. In relation to those parts of Wales which are within those catchment areas, functions under section 92 are exercisable by the National Assembly for Wales concurrently with the Secretary of State. By virtue of section 162 of, and paragraph 30 of Schedule 11 to, the Government of Wales Act 2006 (c. 32) functions under sections 92 and 219 now vest in the Welsh Ministers.
