The following terms are defined in the Regional Water and Soil Plan for Northland

Applies to any waste or waste water to be treated and or/disposed of.

Animal effluent:
Dung and urine from animals (not human effluent) kept in captivity. This does not include dung and urine deposited by individual animals that have been put out to graze.

Farm wastewater:
All waste water and solid matter leaving:

  • A farm dairy
  • Dairy yard
  • Feedpad
  • Stand-off area
  • Stock, sale and holding yards
  • Wintering barn
  • Loafing pad
  • Calf rearing barn
  • Piggery
  • Poultry farm
  • Adjacent entrance and exit races
  • Farm transit races when used for stand-off
  • Stock underpasses or similar.

Also including:

  • Animal effluent
  • Wash-down water
  • Pit washings
  • Sediment
  • Milk and milk residue
  • Supplementary feed
  • Molasses
  • Detergents
  • Soil
  • Sterilising agents and other residues associated with routine farming practices.

Permitted activities:
The discharge of farm dairy effluent to land is considered a 'permitted activity', provided the application complies with the criteria stated in rule 16.1 of the water and soil plan.

Discretionary activities:
Any system which may discharge treated effluent to water, or does not consistently meet the 'permitted activity' criteria, is considered 'discretionary' and requires resource consent.

Resource consent:
Consents are issued with specific conditions regarding infrastructure and the operation of each individual dairy farm. The purpose of resource consent is to allow for the discharge of well-treated effluent to water when conditions are not suitable for land application, provided the effects on the receiving waters are within prescribed limits.

Prohibited activities:
The discharge of treated animal effluent to high-value dune lakes and their tributaries or to other high value waterways is prohibited (lakes and rivers deemed to have outstanding values can be found in Appendix 18 of the water and soil plan).

The discharge of untreated animal effluent to water is also prohibited.

Resource Management Act (1991):
Section 15 (1)(b) of the act states that no person may discharge any contaminant to water or to land in circumstances which may result in that contaminant entering water; unless the discharge is expressly allowed by a national environmental standard, resource consent or regional rule.

Discharges to water:
The discharge of untreated effluent (or any contaminant) to water is not permitted, unless expressly allowed by resource consent.
