Contaminant behaviour

  • Nitrogen – “elusive”
  • Phosphorus – “sticky”
  • Diffuse vs point source

SLIDE 3

The proposed Plan

  • Two stage process for the proposed

Plan

  • Ruamahanga Whaitua Committee to

identify f/w objectives, values and attributes

slide-4
SLIDE 4

Policy summary

  • Progressively reduce wastewater

discharges directly to water

  • Minimise discharges of sediment to

water

  • Reduce and minimise contaminant

discharges from agricultural land use

slide-5
SLIDE 5

Policy summary continued

  • Rural land use managed through good

practice

  • Riparian management is encouraged
  • Farm planning is encouraged
  • Sub-catchments prioritised for further

investigation (nutrients)

Rule summary

  • Community wastewater discharges

require resource consent

  • Direct discharges of sediment directly

to water usually requires consent

  • Agricultural land uses are usually

permitted

Non regulatory: Nutrients

  • Non-reg nutrient management

programme is recent

  • 31 plans in whaitua
  • Structure of plans
  • Positive relationships with landowners

SLIDE 8

Key issues for sediment policy

  • Scale of work required to reduce

sediment

  • Quantifying sediment loss and links to

policy

  • Sediment and P links

Non-reg approaches: sediment

  • Voluntary hill country erosion

programme

  • Farm plans: what’s in them?
  • Coverage of hill country work

programme

Non-reg approaches: sediment

  • Grant rate that subsidises cost of pole

planting and afforestation / reversion

  • Changes in grant rate over time
  • Targeting high priority LUC classes
  • Other methods

Discussion sediment

  • Rate of work: scale
  • Erosion vs sediment reduction
  • Will all erosion prone land be managed

with this approach. Equity

  • Measuring, monitoring, and tracking

changes
