Rule 14 Discharge of stock dip

Updated 23 November 2012 11:42am

The discharge of stock dip effluent onto or into land is a Permitted Activity provided

(a) the discharge is more than 20 metres from any surface water body, farm drain, water supply race, or the coastal marine area; and

(b) the application rate throughout the disposal area does not exceed 0.5 mm per day.

Explanation. The Agrichemical Users’ Code of Practice (NZS 8409:1995) recommends that spent (stripped) dip wash can be spread onto suitable land at low application rates (Appendix GG3 of Part 6). The rate suggested in the Code is less than 5,000 litres per hectare. On a daily basis, this equates to 0.5 mm/day, or two square metres of land for every litre of dip. This application rate is low enough to avoid percolation to groundwater in porous soils and runoff to surface water in non-porous soils.
