Will the Tukituki get better?

Will the Tukituki get better?

Maybe. Maybe not.

The Board of Inquiry (BOI), in its final decision, appears to think it has rescued the Tukituki.

It has required Farm Environmental Management Plans (FEMPs) in which farmers must commit to how they will meet specified nutrient (nitrogen) leaching limits deemed acceptable for their soil conditions (as indicated by the so-called LUC system). Farmers will need to use farming practices that best enable them to meet the limits.

In turn, the cumulative nutrient load in the river (measured most critically in terms of dissolved inorganic nitrogen, DIN) associated with all farming cannot exceed 0.8 mg/L. This compares to DIN limits of 0.44 mg/L set for the Manawatu-Wanganui and Otago regions. So it’s a good limit, not the best.

This limit – opposed by HBRC – was accepted by the BOI on the basis of evidence from environmentalists, who argued that the overall biological health of the river ecosystem was already harmfully affected by current nutrient run-off in the river. HBRC had argued for significantly higher nitrogen limits based on a more narrow measure – fish toxicity. The higher HBRC limit was seen as an enabler of farming intensification in the catchment (i.e., an enabler of the dam).

That the BOI accepted the case for a DIN limit is a victory for the health of the Tukituki.

Some measuring points in the Tukituki catchment presently exceed the 0.8 DIN limit; some do not. In its own calculations, the BOI considered that a small amount of ‘headroom’ for more nitrogen in the river presently existed and therefore the DIN limit was not unduly harsh.

The individual on-farm leaching limits and the overall catchment DIN limit are intended to work together. As the BOI sees it:

“Effective nitrogen management requires a two-pronged approach. The first component involves the setting of on-land root zone leaching limits which will serve as an important control at the source of the leaching process (the fence at the top of the cliff). The other component involves the setting of in-stream nitrate-nitrogen and DIN limits which will serve as a check as to the effectiveness of the LUC leaching rate control.”

Will this approach improve water quality in the Tukituki?
Environmental advocates believe the on-farm leaching limits will ultimately need to be ratcheted lower and embedded in consents in order to meet the DIN limit … and that the DIN limit itself might need to be lowered.

In its final decision, the BOI seemed to anticipate that outcome, saying:

“It is the responsibility of HBRC to avoid the exceedence of DIN limits in the receiving water by regulating the level of nitrogen discharged at the root zone by the farmer and monitoring subsequent DIN concentration in the receiving water. If observed DIN levels are too high then future adjustment by HBRC of the LUC root zone leaching rates may be required.”

And further, in its reasoning for not now setting a lower/tougher DIN limit, the BOI says:

“As water quality science advances a different DIN limit may emerge as a more appropriate level. In the meantime the Board sees the DIN limit of 0.8 mg/L as a pragmatic level that appropriately protects ecological health while enabling more intensive land use.”

But can we, as the “pragmatic” BOI hopes, both have our cake and eat it too? Or has the BOI simply pushed back the day of reckoning when we finally actually decide whether, as Councillor Rex Graham says, “It’s time for farmers to adapt to the river instead of the river adapting to the farmers”?

In all likelihood, if the BOI-ordered regime stands (at this writing, the involved parties have 10 more working days to file legal appeals), sooner or later the Regional Council will have the same political hot potato back on its hands.

If the DIN limit is exceeded a few years down the road, environmentalists will argue for ratcheting down the on-farm leaching rates, as the BOI foresees. But the HBRC, if it maintains its historic and current mindset, can be expected to say: NO, we can’t do that … we’ve already built a dam and farmers have borrowed millions to irrigate and intensify. We must raise the DIN limit instead … or better still, toss that approach entirely, and switch to more accommodating fish toxicity limits.

Surely, you say, that’s not a possibility. Hasn’t the BOI, having studied the matter for over a year, definitively ordered a regime based on DIN limits?

Yes, they did. But, for all practical purposes, the BOI is already history. The political wheel is already turning.

Today, the Government announced its new National Policy Statement for Freshwater Management (download here). It’s a wimpy disappointment, as expected. And what measure does this NPS adopt for assessing and protecting water quality – fish toxicity! Exactly what the BOI rejected.

So stay tuned folks, the Tukituki ain’t getting better yet. And that’s without the farming intensification a potential dam will encourage.

The BOI might well turn out to be a minor bump in the road — mere road kill — for the dam juggernaut.

Patience: Drive Safe

Be patient before passing is the AA's message for drivers this Labour weekend.

"People taking crazy risks to get past other vehicles is one of the most dangerous things on the road,” says AA spokesperson Dylan Thomsen.

“The weather is looking good for the long weekend so the roads will be busy. Unfortunately, that also increases the chances of people getting frustrated and trying a risky passing manoeuvre. When they get past, there will probably be more traffic up ahead anyway so it won’t get people there faster.” More>>
