Sludge (Use in Agriculture) Regulations (Northern Ireland) 1990 (S.I. No. 245 of 1990).

These Regulations implement for Northern Ireland Council Directive No. 86/278/EEC on the protection of the environment, and in particular of the soil, when sewage sludge is used in agriculture. They, among other things- prohibit sludge from sewage plants from being used in agriculture unless specified requirements are fulfilled; specify precautions which must be taken after sludge from sewage plants or septic tanks is used on agricultural land; impose certain obligations regarding data on sludge producers and occupiers of agricultural land. The sludge shall be used in such a way that account is taken of the nutrient needs of the plants and that the quality of the soil and of the surface and ground water is not impaired.
