General guidelines regarding consents for discharges to air are as follows:
- Small intensive poultry farms (of less than 30,000 poultry) generally do not require consent under the Regional Air Plan for Taranaki.
- All poultry operations must ensure discharge does not result in objectionable odour, or dust at or beyond the boundary of the property.
- Operations larger than 30,000 poultry kept at one time require resource consent to discharge contaminants to air.
Pig farms of 25 pigs or fewer do not require resource consent. However, Plan rules state that discharge must not result in objectionable odour, or dust at or beyond the boundary of a property.
Farm dairy effluent
All discharges of treated farm dairy effluent require resource consent for discharge to land or water under the Regional Freshwater Plan for Taranaki. In terms of air quality, you do not need resource consent as long as:
- The spray irrigation or the ponds contain effluent from your farm only.
- No spray or offensive smells drift onto neighbouring properties.
- The spray or the ponds are more than 150m from any house (or other inhabited building).
- Surface ponding does not occur for more than three hours.
If you cannot meet any of these requirements, you will need to apply for resource consent (an air discharge permit).
