Emergency milk disposal information

Emergency milk disposal information

Following the major disruption to the gas pipeline supply network to the upper North Island, emergency disposal of milk may be required over the coming days.

The Bay of Plenty Regional Council has created the following guidance on how to safely dispose of your milk.

Main points to note are:

  • Irrigation of waste milk to land is the preferred option of disposal
  • Irrigate to land at a dilution of 1:10 with water to avoid damage to pasture
  • Where possible, irrigate onto recently grazed pasture
  • Flush the pasture with clean water to rinse the milk residues from foliage into the soil following irrigation (this will also help to reduce odour)
  • Use as much land area as practically possible and do not apply more than 50,000L/Ha or 5L/m2
  • If possible, use land that can be worked following application
  • Monitor the application to ensure that there is no discharge to water bodies
  • Prevent ponding of wastewater and overland flow into waterways, including drains, when irrigating
  • Try to avoid irrigating near property boundaries to minimise odour potential
  • No more than four days worth of milk should be discharged to your effluent pond system
  • Correctly sized oxidation ponds can cope with milk for a limited time. However odour could be a problem after four or five days. Any odour produced should settle within a week or so of stopping the discharge.

If you're unable to dispose of your milk in accordance with the guide linked above, please contact Bay of Plenty Regional Council Pollution Prevention Team Leader, Steve Pickles on 0800 884 880.
