Title: Inspection on farms


1
Inspection on farms experiences from
DenmarkThe danish approach to IPPC on livestock
farming
  • by Peter 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)
Species Average emission Worst case (summer)
Cattle 25 40
Poultry 80 120
Pigs Piglet Fattening pig Sow 140 100 40 210 150 60
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
Monday Friday 7.00-18.00 Saturday 7.00-14.00 Monday Friday 18.00-22.00 Saturday 14.00-22.00 Sunday 7.00-22.00 All days 22.00-7.00
55 dB (A) 45 dB (A) 45 dB (A) (max. 55 dB (A) )
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/i
    lf_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
  • gt 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
  • lt 4200 pigs ? 25
  • 4200 - 8750 pigs ? 60
  • gt 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)
