  1. Inspection on farms – experiences from DenmarkThe danish approach to IPPC on livestock farming byPeter Dorff Hansen Environmental Division Ringsted Municipality

  2. Main environmental problems • Odour problem (from the farm or the field) • Noise (animals, transport, field) • Surface water (manure/slurry) • Groundwater (pesticides, oil, manure/slurry) • Emissions of ammonia gas (nature) • Emissions of greenhouse gases (CO2, CH4)

  3. Regulation in relation to….. • Regional planning - County Council • Terms in approval - Municipality • BREF-note (Best Available Techniques) • National legal notice – EPA • Case to case assessment and decision in relation to pollution prevention

  4. Regional Planning • Assesment of environmental impact from project in relation to: Nature, culture/landscape, groundwater, rivers/lakes etc. • Council Directive 85/337/EEC of 27 June 1985 on the assessment of the effects of certain public and private projects on the environment

  5. Environmental approval • Size, type and composition of livestock • Activities and techniques • Odour assesment • Noise assesment • Wastewater treatment

  6. Size and composition of livestock • Capacity of farm - size of buildings • Production level • Composition of animals (weight, number) • Documentation on production level (deliverance to slaughtery)

  7. Activities and techniques • Map of location (buildings, size, function) • Housing system – heating, ventilation • Feeding system • Drinkwater supply • Storagesystem for manure/slurry

  8. Odour assesment Emission on odour depends on: • Type of livestock • Size of livestock • Outside temperature (climate) • (Feeding system, technology, handling…)

  9. Odour emissions from livestock (unit/sec pr. 1000 kg)

  10. Differencies in tolerance • Area no. I: Town areas (1 unit/m3) • Area no. II: Villages (3 unit/m3) • Area no. III: Rural areas (10 unit/m3) • Example on odour assessment based on ”Guidelines on assessment of odour and reducing of inconviniences from livestocks”

  11. Noise assesment – guidelines on accepted noiselevel in rural areas

  12. Wastewater treatment • Individual approval on wastewater • Oil separated and led to closed tank • Spread on fields – on certain conditions

  13. Applied techniques and BAT • The intensive Rearing of Poultry and Pigs BREF (Best Available Techniques reference document), July 2003 • http://europa.eu.int/comm/environment/ippc/brefs/ilf_final_0703.pdf

  14. Danish EPA - Legal notice on livestock farming • Limits on distance • Restrictions on handling and storage of manure and slurry • Limits on density of animals pr. hectare • Restrictions on handling and storage of chemicals • Obligation on inform in case of changes/expanding

  15. Limits on distance • > 50 meters to neighbors • Only in rural areas (not town/village areas) • More than 300 m to village • Demands on distance to watersupply, rivers, public roads, buildings, food industry

  16. Handling and storage of manure/slurry • Min. 9 month storage capacity • Demands on storage construction and control • Cover on storage • Restriction on spreading (not in weekends, not from harvest to february) • Demands to spreading equipment

  17. Limits on density of animals Demands on owned field area: • < 4200 pigs  25 % • 4200 - 8750 pigs  60 % • > 8750 pigs  100 % Demands on harmonie livestock/field size: • Max. 49 pigs pr. hectare

  18. Restrictions in relation to chemicals • Education and certificate for user • Updated list on approved pesticides • Safe storage • Cleaning in field

  19. New techniques – coming up • Acid additives to slurry – Saving nutrient (Ammonia – NH3) • Biofilter – air cleaning system • Ozone – air cleaning system

  20. Final Remarks • To day - Most environmental problems can/must be solved at the moment of location and/or changes • In future – assesment on effect of new techniques (experiences and documentation)
