Court Cancels Enforcement Order

Court cancels enforcement order; farmer can resume cultivation
By Lucy Ibbotson, on Saturday March 2014
Otago Daily Times

A Hawea Flat farmer can continue cultivating his land after an Environment Court ruling found in his favour yesterday.

The court cancelled an interim enforcement order which had stopped Dougal Innes from carrying out any further vegetation clearance or discing on his property next to the Clutha River since March 3.

The case was brought by the Royal Forest and Bird Protection Society of New Zealand, which said significant native vegetation was being destroyed by the cultivation work.

Resource consent should have been required under the rules of the Queenstown Lakes District Council's district plan, the society said.

In delivering his finding verbally yesterday following a four-day hearing in Queenstown, Judge John Hassan said continuation of the interim order would serve ''no valid resource management purpose''.

Mr Innes could resume developing the area of land he had already cleared and disced, as it was unlikely any indigenous vegetation - as defined by the district plan - remained or could be recovered. [Editor's note: on the contrary, the evidence showed significant indigenous vegetation had survived the discs on the lower terrace, which would recover.]

It was unlikely the district plan would be breached by any further disturbance.

But the court found clearance of indigenous vegetation on the as-yet-uncultivated remaining land would be a restricted discretionary activity.

Mr Innes could not cultivate that area without first getting resource consent, if his proposed activity required it.

The court was satisfied Mr Innes had ''demonstrated at least good intent'', Judge Hassan said.

That was evident in the fact he had not disturbed areas of his land containing historical features while waiting for advice from an archaeological authority and in the patience he had shown during the Forest and Bird legal action.

Forest and Bird had argued environmental effects were the critical consideration, rather than the effects on the parties.

But Judge Hassan said it was relevant to consider financial hardship to a person.

The court considered it unjust to maintain the order for reasons including the ''undue financial hardship'' it would impose on Mr Innes who had acted responsibly and with due diligence before beginning clearance work.

Council officers who advised Mr Innes he did not require resource consent for the activity ''could not be said to have obviously got it wrong either''.

It was ''most unfortunate that due to the council's systems error'' the ecological assessment findings of the property - noting the presence of indigenous vegetation - were not provided.

Mr Innes - who had told the court he invested his family's life savings in the property - expressed relief yesterday, following what he described as a stressful few weeks.

''I'm happy, there's no doubt about that.''

He thanked his supporters, including the large number of farmers who had been present in court throughout the hearing.

Following the decision, Forest and Bird Otago Southland field officer Sue Maturin said a special part of Central Otago had been lost.

''If the Queenstown Lakes District Council had acted to stop the destruction as soon as Forest and Bird alerted it, we may not have lost one of the best and biggest remaining areas of short tussock grasslands, cushion fields, and dry land ecosystems in the Upper Clutha Basin.

''This case highlights the need for councils to be much better at advising landowners about their obligations under district plans; to have clear rules to protect biodiversity; and to strongly uphold the integrity of their plans.''

Forest and Bird would decide on any further action after it had seen the written findings, its lawyer Sally Gepp said.

Ruling Expected Today ...

Ruling expected today on land-clearance caseBy Lucy Ibbotson, on Friday 28 March 2014
Otago Daily Times

Should farming activities or protection of indigenous vegetation take priority on a contentious piece of privately owned land at Hawea Flat?

That is the question the Environment Court will answer today, in a decision Judge John Hassan says is ''by no means an easy one''.

The ruling could have significant implications for the farming industry if an interim enforcement order issued against farmer Dougal Innes earlier this month is upheld, lawyer Graeme Todd submitted to the court in Queenstown yesterday.

The order was obtained by the Royal Forest and Bird Protection Society of New Zealand, which considers protecting the indigenous vegetation on Mr Innes' land a matter of ''national importance''.

Mr Innes had already disced a large part of the site before his farming activities were halted by the order, which he has applied to the court to have cancelled.

In closing submissions, Forest and Bird lawyer Sally Gepp said the consequences of Mr Innes not being able to cultivate his land this year should not override a clear breach of the district plan, the adverse effects already caused at the site and the further effects which would occur if the order was cancelled.

''Protection of significant indigenous vegetation is a matter of national importance which all decision-makers must recognise and provide for,'' Ms Gepp said.

The most appropriate forum for considering Mr Innes' proposed farming activity was a resource consent process where all parties could have a view on the matter through notification.

''[Mr Innes] is required to seek consent for indigenous vegetation clearance like any other person.''

It was ''not an ex-appropriation of his rights'', but rather a normal and legal application of the district plan.
Mr Todd, who is acting for neighbouring landowner and interested party James Cooper, said the significant question if the interim order was upheld was: which landowner in the district would be next?

''If farmers are required to spend thousands of dollars applying for resource consents for every act of clearance of their land and if their ability to cultivate and farm their land is curtailed by a standard that they are not allowed to clear pasture even if a few indigenous species are present on a site, this has significant implications for the farming industry not only in this region but in other regions.''

Mr Innes' lawyer, Jan Caunter, said Mr Innes had ''asked all of the right questions and sought advice from all the right places'' on matters relevant to buying the property and which might have affected his ability to use it.

''He sought LIM reports which did not alert him to the presence of indigenous vegetation on the site. It did, however, alert him to activities that had previously been approved on the site, which were in many respects similar to what he wished to do,'' Ms Caunter said.

''[He] received what essentially amounted to 'yes, you can go ahead'.''

Federated Farmers lawyer Richard Gardner said because the land had been used for primary production purposes for a long time and cultivated on occasion for those purposes, Mr Innes' claims to existing use rights were ''well founded''.

''There is no basis upon which the interim enforcement order can be sustained ... Mr Innes and the other farmers in the Queenstown Lakes district who are concerned about the implications of the interim enforcement order should be left to go about their lawful farming activities,'' Mr Gardner said.

Further consideration was given to a compromise, as mooted by Mr Todd on Wednesday.

Judge Hassan asked three ecologists - who were appearing for the council, Mr Innes and Forest and Bird - their view on an appropriate width for a possible buffer zone on the southern boundary of Mr Innes' property, to protect indigenous vegetation on neighbouring land owned by Contact Energy.

Their opinions ranged from 20m to 200m.

Land Compromise Raised

Land compromise raised
By Lucy Ibbotson, on Thursday 27 March 2014
Otago Daily Times

The possibility of a ''compromise situation'' benefiting both sides of a land dispute was raised in the Environment Court sitting in Queenstown yesterday.

Detailed scientific evidence was given by three ecologists on day three of a hearing to consider Dougal Innes' application to cancel an interim enforcement order stopping him from farming his land at Hawea Flat.

The order was obtained by the Royal Forest and Bird Society of New Zealand, which has concerns about the potential loss of important indigenous vegetation on the site, which has already been largely cleared and disced by Mr Innes.

Arrowtown ecological consultant Glenn Davis appeared for the Queenstown Lakes District Council, having surveyed Mr Innes' land as part of an ongoing council project to identify areas of significant indigenous vegetation throughout the district.

During cross-examination by lawyer Graeme Todd - representing neighbouring landowner James Cooper, an interested party in the proceedings - Mr Davis was asked what he believed should happen with the land and whether it should be ''locked up'' in the future from further development.

''I would like to see some effort made to at least restore some of the land or maintain at least some of the disturbed land,'' Mr Davis replied.

Mr Todd said maintaining the interim enforcement order would have ''catastrophic implications'' for Mr Innes, as it would prevent him from gaining any income from the land.

He asked if Mr Davis had therefore considered a ''compromise situation'', where the order would be uplifted and some other means of protection applied.

Mr Davis said he had thought of other options, including leaving aside some of the land that had already been disturbed to provide for a ''sequence of vegetation'' spanning the site from the Clutha River to the upper terraces.

''In doing so, there would need to be some reduction in the area that Mr Innes has available for farming.''

Based on his observations, Mr Davis told the court further physical disturbance of the site would exacerbate the ''significant damage'' that had already occurred, but sowing and irrigating the land, as intended by Mr Innes, would ''fundamentally alter'' the whole site and the important plant communities found there.

The hearing continues in Queenstown today before Judge John Hassan and commissioners John Mills and Ian Buchanan. A decision is expected to be issued verbally by the court today or tomorrow.

The case is attracting a large amount of interest, with members of the farming community present each day in the public gallery and the district's Mayor, Vanessa van Uden, and Waitaki MP Jacqui Dean in attendance yesterday.

Tensions At Hearing

Tensions at hearing
By Lucy Ibbotson, on Wednesday 26th March 2014
Otago Daily Times

The Queenstown Lakes District Council's level of culpability came under the spotlight yesterday in a land debate pitting farmers against conservationists.

Representatives from both sides packed the public gallery on day two of an Environment Court hearing in Queenstown considering the cancellation of an interim enforcement order against Hawea Flat farmer Dougal Innes.

The order was obtained earlier this month by the Royal Forest and Bird Society of New Zealand to prevent Mr Innes carrying out further native vegetation clearance and discing work on his land next to the Clutha River, which is considered to be ecologically important.

During a break in proceedings, tensions were evident between some of the Upper Clutha farmers and Forest and Bird members.

The council's planning and development general manager, Marc Bretherton, said field notes prepared by the QLDC's ecological consultant identifying the site's conservation values had mistakenly not been provided to the council when Mr Innes sought advice on whether his proposed farming operation would require resource consent.

Mr Bretherton and council planner Ian Greaves subsequently advised Mr Innes it appeared there would be no breach of the district plan.

''Based on the information that council held, there was nothing telling me that he needed a resource consent,'' Mr Bretherton said.

''Certainly, if we'd had possession of that [ecological] information, that would have better informed our understanding of the site ... and we would have been better able to advise Mr Innes.''

Mr Innes was advised obtaining further information himself would ''assist him in determining categorically whether resource consent was or was not required'', Mr Bretherton said.

Mr Greaves said he did not tell Mr Innes to seek additional advice from an ecologist.

However, as it was Mr Innes' obligation to ensure he complied with the district plan rule on indigenous vegetation clearance, it would have been prudent to do so, he said.

''So every time a farmer wants to clear his or her land and they're not sure whether they've got any indigenous vegetation on it, they're going to have to secure the assistance of an ecologist?'' Mr Innes' lawyer, Jan Caunter, asked, to which Mr Greaves replied, ''Yes.''

Both Mr Bretherton and Mr Greaves agreed with commissioner John Mills there was nothing to indicate Mr Innes was ''anything but straightforward'' and had acted on the best information available to him.
Earlier, Mr Mills asked Forest and Bird field officer Jen Miller for her view of the council's response to Mr Innes' inquiries.

''To be frank, if I was Mr Innes I would feel less than satisfied. I think it was not really giving him any direction either way ... Perhaps the council might have been more helpful to him in terms of the information they had available,'' Ms Miller said.

Wanaka landscape architect Anne Steven, appearing for Forest and Bird, acknowledged it was ''somewhat unreasonable'' to expect Mr Innes, as a private rural landowner, to be aware of the ecological information relating to the land.

Mr Innes also took the stand.

''I've invested our entire savings in this property . . . and I didn't intend to be in this position we are now,'' he told the court.

Asked by Forest and Bird lawyer Sally Gepp whether he would keep cultivating the land if the interim enforcement order was cancelled, Mr Innes responded: ''I intend to farm the property, so yes, that's the reason I purchased it.''

Mr Innes' planner, Duncan White, told the court the attendance of many farmers at the hearing reflected concerns in the farming community about the wider implications of the interim enforcement order against Mr Innes.

"We Have A Rule In The Plan ..."

We have a rule in the plan
By Lucy Ibbotson, on Tuesday 25 March 2014
Otago Daily Times

A young family facing ''financial ruin'' must be given the same consideration as the protection of ecological values on Hawea Flat land, it was submitted in the Environment Court in Queenstown yesterday.

A hearing is being held this week to consider cancellation of an interim enforcement order requiring farmer Dougal Innes to stop clearance of native vegetation on land he has a purchase agreement on above the Clutha River at Hawea Flat.

Mr Innes has already cleared a large amount of vegetation and carried out discing on the land, which has been assessed by government departments as having high conservation values.

The Royal Forest and Bird Protection Society of New Zealand deemed Mr Innes' actions illegal and successfully applied to the Environment Court for the interim enforcement order.

It was served on Mr Innes, as respondent, and the Queenstown Lakes District Council earlier this month, around the same time the council issued an abatement notice on Mr Innes.

However, in written legal submissions, Mr Innes' lawyer Jan Caunter said her client had consulted the council and was at no stage advised he needed resource consent.

''If we had somebody who had flagrantly breached the [district] plan that would be quite different. But that is not what has occurred here,'' Ms Caunter told the court.

''... It is submitted that the information provided to Mr Innes by the council and the implication that no resource consent was required is relevant to the court's assessment.''

The court needed to consider not only the potential for damage to any indigenous vegetation on the site, but the impact on Mr Innes of not being able to complete the cultivation work, which would leave him with ''no reasonable use of his land'', Ms Caunter said.

''Mr Innes and his young family are facing financial ruin if the land is protected from further development,'' her written summary of background facts stated.

Forest and Bird lawyer Peter Anderson said the effects on the environment of cancelling the interim enforcement order were a ''critical'' consideration and should be the focus, rather than the effects on the parties.

He said if there was a strong case for an enforcement order and if there was likely to be significant irreparable adverse effects if the interim order was cancelled, there would need to be a ''highly compelling reason'' for its cancellation.

Ms Caunter said given the ''significant'' level of disagreement among the lawyers, planners and ecologists involved in the case on how the district plan rules relating to indigenous vegetation should be interpreted, it would be especially difficult for a layperson such as Mr Innes to accurately interpret them.

''There are lots of different ways of looking at the rule and that in itself is causing me great concern, that we have a rule in the plan that nobody understands.''

Judge John Hassan instructed ecologists acting for Mr Innes, Forest and Bird and the council to jointly respond to a series of questions aimed at providing clarity on the definition of indigenous vegetation. They will report back to the court today.

The hearing is expected to continue until Thursday, when the court will issue a verbal decision on whether the interim enforcement order is to be confirmed or cancelled.

Dairy farmer James Cooper, a neighbour of the site, and Federated Farmers are interested parties in the court process.

Court Date For Hearing

Court date for hearing
By Mark Price, on Saturday 15 March 2014
Otago Daily Times

The Environment Court will begin a two-day hearing of a Hawea Flat land dispute in the Queenstown Court on March 24.

The hearing is the result of an enforcement order obtained from the court by the Royal Forest and Bird Protection Society on March 3.

The society objected to the ploughing of the 590ha area of land above the Clutha River at South Hawea Flat, near Wanaka.

Canterbury West Coast field officer Jen Miller told the Otago Daily Times a pre-hearing conference between the parties was held on Thursday.

The action the society has taken is against Dugald Innes, who is understood to have a right to purchase the land in question from Big River Paradise Ltd.

Neighbour James Cooper is listed in court documents as an interested party.

Environment Court Halts Development

Environment Court halts development
By Lucy Ibbotson, on Tuesday 4 March 2014
Otago Daily Times

The Environment Court and the Queenstown Lakes District Council have halted further development of a controversial piece of land above the Clutha River at Hawea Flat.

An interim enforcement order was issued by the Environment Court yesterday and served on farmer Dugald Innes, as respondent, and the council, following an application by the Royal Forest and Bird Protection Society on Friday.

Mr Innes had cleared native vegetation and ploughed the land, which has been assessed by government departments as having high conservation values. His actions were deemed illegal by Forest and Bird.

The court order prevents Mr Innes from further clearance of indigenous vegetation as defined by the Queenstown Lakes district plan, or from watering, irrigating, oversowing or top-dressing any part of the subject land.

Environment Court Judge John Hassan said while evidence provided by Forest and Bird was limited, it appeared there was a ''real risk of irreparable environmental damage''.

He said the urgency of the situation, as a result of the recent ploughing of the site, was ''not of the applicant's making''.

''The evidence shows a history of exchanges in recent weeks between the applicant and the council, in terms of which the applicant was urging that the council investigate and act.''

Council general manager, planning and development, Marc Bretherton told the ODT on Friday - the same day the agricultural contractor was seen leaving the site - that based on the council's assessment of the situation and legal advice, it had not issued an abatement notice nor any other form of enforcement proceedings.

However, yesterday, QLDC lawyers advised Forest and Bird the council issued an abatement notice on Mr Innes on Saturday evening and would be serving abatement notices on landowners Big River Paradise Ltd and Sharyn Campbell yesterday afternoon.

QLDC senior communications adviser Michele Poole said because the matter was before the court the council would not make any further comment as it was ''not appropriate to do so''.

Forest and Bird field officer Jen Miller said the society had never undertaken an application for an interim enforcement order before, but ''believed such a serious step was warranted because of the significance of the vegetation and the failure of council to take what it considered appropriate action''.

Mr Innes could challenge the interim order, in which case there would be a hearing at short notice, Ms Miller said.

''The interim order is effectively maintaining the status quo while the court process on whether enforcement orders should be issued ... runs its course. This is likely to involve an evidence exchange and a hearing ... [and] take a few months.''

Forest and Bird had indicated it would modify its enforcement order application once it had more advice on what was needed to rehabilitate the site.

The court decision states the interim order will no longer apply if Mr Innes obtains a resource consent for the prohibited activities, which are considered discretionary under the district plan.

Court Order Sought

Court order sought
By Mark Price, on Monday 3 March 2014
Otago Daily Times

The Royal Forest and Bird Protection Society has gone to the Environment Court to stop further cultivation of 590ha of land above the Clutha River at south Hawea Flat.

Society field officer Jen Miller told the Otago Daily Times yesterday the society regarded the clearance and cultivation of the land last month as illegal.

Lawyers for the society had lodged an application for an interim enforcement order, which compels a landowner to comply with the Resource Management Act or a district plan.

The move follows the society's dissatisfaction with the Queenstown Lakes District Council's handling of the matter.

Clutha Mata-Au River Parkway Group spokesman Lewis Verduyn-Cassels said he watched the agricultural contractor leave the site on Friday morning.

''Most of the site has been trashed,'' Verduyn-Cassels said.

''It's an ecological disaster. That's what it is.''

He recounted to the Otago Daily Times the names of rare native plants that had been ploughed up.

Council general manager, planning and development, Marc Bretherton said in an email to the ODT the council's district plan contained a list of threatened plants, and rules which referred to the list.

''The ecological report specific to the property in question identifies a single species as threatened.

''This species is not included in the district plan.''

Mr Bretherton said also that, contrary to media reports, the council had never said resource consent was not required for the cultivation work.

It investigated the concerns of the society and visited the site last Thursday where it ''confirmed that no breach of the district plan had occurred''.

''Acting on the information available, there was no basis for issuing an abatement notice or commencing enforcement proceedings,'' he said.

''When site-specific ecological advice was subsequently obtained, the landowner was contacted to advise that an ecological report and possibly resource consent would be required.

''At this point, council became aware that the site had been ploughed.''

Mr Bretherton said the council had ''not issued an abatement notice nor any other form of enforcement proceedings''. Forest and Bird lawyer Peter Anderson has written to the council advising it to issue the landowner with an abatement notice to remediate the ''damage''.

He called for a ''thorough'' ecological survey, the site not to be watered, oversown or topdressed, all grazing to cease and rabbit control to be carried out.

The council's website shows the land is owned by Big River Paradise Ltd.

Cultivation Legal Opinion Sought

Cultivation legal opinion sought
By Mark Price, on Friday 28 February 2014
Otago Daliy Times

The Queenstown Lakes District Council is seeking a legal opinion over the cultivation of land at south Hawea Flat, near Wanaka.

Before and after clearance of threatened vegetation
The council initially told landowner Dugald Innes consent was not required and cultivation began.

Then, after taking ''site-specific ecological advice'' on Monday, the council told Mr Innes an ecological report ''and possibly resource consent'' would be required.

In response to an Otago Daily Times request for clarification of the council's position yesterday, general manager, planning and development, Marc Bretherton said the council was seeking a ''more detailed legal opinion''.

''Once we have received it, we will be better placed to determine what, if any, further action is required.''

The Royal Forest and Bird Protection Society of New Zealand has strongly criticised the council for allowing cultivation without resource consent, as it says the land is ecologically important.

It has warned it could take Environment Court action against the council for failing in its district plan obligations.

A visit to the site by the ODT yesterday found cultivation work being carried out. However, a council spokeswoman said later this was on land next to the area the society was concerned about.

Forest and Bird acting Otago-Southland field officer Jen Miller said even this work required the council to be sure resource consent was not required.

''I think what we are witnessing here is an extraordinary litany of council ineptitude.

''On Thursday of last week, they had all the information they needed to at least raise some red flags around the legality of the work that was being carried out.''

Ms Miller said the society had made several attempts to contact the council yesterday but had received no response.

Mr Innes has not responded to ODT messages.

Council Changes View On Cultivation

Council changes view on cultivation of farmland 
By Lucy Ibbotson and Mark Price, on Wednesday 26 February 2014
Otago Daily Times 

The Queenstown Lakes District Council has had a change of heart over allowing the cultivation of land considered to be ecologically important.

Last week, the council told a south Hawea Flat farmer he could plough his land without resource consent, but yesterday, after much of the land had already been ploughed or cleared of vegetation, it said consent could be needed after all.

Concerns were raised last week by the Royal Forest and Bird Protection Society of New Zealand - along with a Landcare Research scientist, the Clutha Mata-Au River Parkway group, Wanaka landscape architect Anne Steven and members of the public - about the alleged ''unlawful'' clearance of native vegetation on the private land on the true left of the Clutha River, upriver of Kane Rd.

They considered the land should be protected because of its rare and threatened ecosystems.

Forest and Bird acting Otago-Southland field officer Jen Miller wrote to the QLDC requesting the clearance work be stopped until the owner had sought consent.

The landowner referred to in email correspondence between QLDC and Forest and Bird was Dugald Innes, who did not return calls yesterday.

In a letter to the QLDC yesterday, Forest and Bird lawyer Peter Anderson said the clearance activity breached the ecological provisions of the district plan, which the council had an obligation to enforce.

''It has failed to fulfil this obligation.''

Forest and Bird could refer the matter to the Environment Court or the Office of the Ombudsman, Mr Anderson wrote, unless the council instructed the landowner to cease the work and reinstate the site as much as possible.

He acknowledged the council could do very little to rectify the situation, as Mr Innes ''will simply and correctly say, I undertook this activity with the council's approval''.

''That the approval was given in error does not alter the fact that highly significant values have been destroyed.''

Yesterday, council general manager, planning and development, Marc Bretherton told the Otago Daily Times the council had investigated the concerns soon as it was aware of them and a site visit last Thursday confirmed there was no breach of the district plan.

''Acting on the information available and in accordance with legal advice, there was no basis for issuing any form of enforcement proceedings prior to the weekend,'' Mr Bretherton said.

However, after site-specific ecological advice was obtained on Monday, the landowner was contacted yesterday morning and told ''an ecological report and possibly resource consent'' would be required.

''At this point the council became aware that the site had been ploughed. We are still assessing whether any further action is appropriate.''

Ms Miller said once dryland farms were converted to irrigated land for more intensive development, rare ecosystems were lost forever.

Contact Undeterred By Hayes Decision

Power companies undeterred by Project Hayes decision
By Lynda Van Kempen, on Tuesday 24 January 2012
Otago Daily Times

In the wake of the Project Hayes decision, it is business as usual for Contact Energy, weighing up options for hydro development on the Clutha River, and Pioneer Generation, looking at small-scale wind farms.

Meridian's decision to shelve its planned $2 billion wind farm on the Lammermoor Range in the Central Otago has had little impact at this stage on Contact and Pioneer's plans.

Contact Clutha hydro project manager Neil Gillespie said the hydro plans were "at a completely different stage to what Meridian was at when it pulled the plug.

They had a consented project.

"We have yet to narrow down the options and decide on a favoured option and we're quite some time away from even having to think about resource consents," Mr Gillespie said.

Contact has been investigating four main hydro options on the upper and lower Clutha, proposing dams at Tuapeka Mouth, Queensberry, Luggate and Beaumont costing between $300 million and $1.5 billion.

The schemes were mooted more than 20 years ago and originated from proposals by Contact's predecessor, the Electricity Corporation of New Zealand.

Ultimately, the Project Hayes decision would have an impact "when we're looking at starting to build, but we're nowhere near that stage", he said.

In the meantime, the company was consulting the community, and analysing options.

The community's views, technical and engineering studies and the effect on the environment were all factors which would be taken into consideration, Mr Gillespie said.

"Nothing's changed for us in what we're doing because of Meridian's decision."

Pioneer Generation chief executive Fraser Jonker said its plans for wind farms were on a vastly smaller scale than Meridian's.

The Environment Court decision in 2009, which cancelled resource consents for Project Hayes, saying the wind farm was inappropriate in an outstanding natural landscape, had influenced the type of wind farm proposals Pioneer had been investigating.

"We would never attempt to place a wind farm in that type of a landscape because it would be too much of hurdle to get it consented. "The projects we have under more investigation at the moment have taken that sort of landscape into consideration," Mr Jonker said.

Pioneer was still talking to several Otago and Southland farmers about the possibility of constructing small-scale wind farms on rural properties, along similar lines to its nine-turbine Mt Stuart wind farm in South Otago.

POWER Struggle

POWER Struggle
Saturday 30 October 2010
The Press

Wild river, a raft, a safety briefing.

Glenn Murdoch, our good natured and we hope responsible guide, goes through the drill. Forward paddle, backward paddle, hold, stop. Drambuie for everyone if you lose your paddle.

Then he gives us the worst-case scenario. This is when the raft capsizes with the crew in the river and not necessarily attached to the boat.

"Keep your legs in front of you and your head looking down the river," he instructs.

The chances of tipping our bulky craft seem remote to a rookie like me but Murdoch, I guess, has to go through the motions like a flight attendant giving a spiel about the aircraft crashing.

We are on the Mokihinui River, which is in a remote northern corner of the West Coast, about 40 kilometres north of Westport. The launching point for our expedition is well inland, just below the fork in the river where the North and South branches meet and just above the 16km Mokihinui Gorge.

If state-owned Meridian Energy wins the day, most of the gorge will flooded up to an 85-metre dam to be built about 15km from the river's mouth. The resulting 14km-long lake will inundate 225 hectares of pristine lowland forest and obviously the stretch of wild river we hope to travel.

Meridian has the project on first base by obtaining the required resource consents from the West Coast Regional and Buller District councils. In March, commissioners decided, two to one, to grant the consents. The Department of Conservation (DOC), Forest & Bird and Whitewater NZ are appealing and the Environment Court is expected to hear the case in 2012.

Forest & Bird field officer Debs Martin, who is sharing a raft with Green Party co-leader Russel Norman (among others), explains Meridian faces another difficult hurdle: for the dam to go ahead, Meridian needs either permission from DOC to flood the land or it needs to acquire the DOC land by swapping it for other land which will provide a net benefit to conservation. Meridian has offered 700ha of land, two blocks of which are in the Mokihinui catchment below the dam.

DOC has completed its evaluation and a draft report recommends a firm "no" to Meridian on all counts. The final decision must be made by the conservation minister.

Martin hopes the area will end up in a conservation park, a process that was "on the table" before Meridian began the consent process.

She accepts the minister could direct the department to withdraw but thinks that unlikely because DOC has thrown "unprecedented" resources at the fight.

It all looks very difficult for Meridian but its Mokihinui project manager, Chris Evans (not on the trip), who has worked on the project for four years, says Meridian will persevere, concentrating for the moment on the appeal. Meridian has withdrawn its DOC flooding application so it can enter more open discussions.

The search for land to satisfy DOC continues, he says: "It's not an easy task when DOC already administers 80 per cent of land on the West Coast."

Back at the river, the launch is getting closer. About 120 people have gathered for a 6.30am start on a dull but mercifully dry morning.

Evidence before the commissioners showed only about 300 people use the area each year. We are certainly going to boost the average.

The event has been organised by the Christchurch White Water Canoe Club, more as a statement than a protest. The assemblage has its fair share of greenies but white water people come in all sorts of political stripes. Norman is the only politician on the trip.

The first step is for the rafts and kayaks to be bundled into nets and slung beneath helicopters for the trip up to the forks. One whitebaiter has set his net in the river just below the very site where the gear and people are loaded. In a scene reminiscent of Apocalypse Now, three helicopters flying neatly behind each other descend in an urgent racket of whining rotors.

The white water people are obviously not keen on the power project. The proposed lake does not stop them using the higher and difficult North Branch of the river but it means they face a dull 14km flat paddle on the descent which is currently broken by numerous boulder- strewn rapids, quieter stretches of green water, sandy beaches, striking rock features and healthy bush.

They concede their kayaks and rafts are not often seen on the river. As the day of our adventure shows, getting kayaks and rafts up the river is a major and expensive exercise.

Although the commissioners saw the loss of white water recreation as a "significant effect" they considered the dam would provide "a more diverse range of opportunities to a much wider group of people".

Hugh Canard, a Christchurch economic development and tourism consultant, whose heroic organisational abilities make the Mokihinui statement such a success, doesn't buy that argument.

He likens his white water colleagues to the endangered blue ducks who will be supplanted by the dam lake.

"We have the same rights as anybody else. Numbers shouldn't come into it. We are saying we are the blue ducks who have been using the river and minding their own business. Then along comes whoever and wants to take it away. You're going to displace blue ducks and introduce mallards."

While a lake would no doubt increase patronage of the area, by that logic a gondola up Aoraki/Mt Cook would be fine because it would do the same thing for the mountain, he says.

In his view the commissioners overlooked that the Mokihinui is one of only three reasonably accessible rivers on the West Coast that can be used by the majority of competent kayakers.

People who want a lake experience on the coast are spoiled for choice with about 100 naturally formed lakes that are under-utilised, he says.

Canard, 68, who has been kayaking since his late 30s, worries the lake will end up like Lake Dunstan at the head of the Clutha Dam - "dead".

"In my lifetime I've seen one river after another either getting diverted, drained or dammed. We've only got 20 per cent left. That's why the Mokihinui is important."

Clyde Dam Highly Problematic

Since the filling of the Dunstan reservoir behind the Clyde dam was completed in 1993, the Clyde dam controversy has faded in the minds of most New Zealanders. But the woes of the last 'think big' project have not gone away. Despite extensive and costly mitigation measures, issues remain regarding gorge instability, faultlines, and reservoir sediment build-up.

The Cairmuir-Dunstan Fault cuts across the gorge just above the dam, and the River Channel Fault disects the dam and the powerhouse. The discovery of the River Channel Fault came as a surprise to dam workers, who uncovered the micro-fractured rock running in a wide band along the riverbed. Obviously, fissured rock is not suitable for dam foundations. The first solution was to pump vast amounts of slurry concrete into the fault, but concerns mounted over the extent and depth of the faultline, and the likely futility of 'dental' concrete.

Finally, experts were called in to determine the extent of the fault issue. It was calculated that the River Channel Fault was 12-15km deep. This lead to a dam re-design in 1982 (during which a sluice channel was omitted leading to later modifications that reduced the dam's MW output by one-third). Subsequent investigations carried out by a team of some 40 geologists revealed serious instability issues throughout the gorge. The result was an incredibly expensive gorge stabilization programme, costing $936 million dollars (2005 value), resulting in the total cost of the project blowing-out to $1.4-1.8 billion dollars. The exact cost is unavailable or unknown, suggesting the true cost could be even higher.

There was considerable doubt over whether or not the dam would be safe, but in the end the government of the day, under Prime Minister Robert Muldoon, refused to admit that the project had been botched, and it was finished, complete with a controversial 'slip-joint' to accommodate earthquakes up to, supposedly, 7 on the Richter Scale.

The 'slip-joint' was hailed as an engineering achievement, but one of New Zealand's most respected geo-technical scientists at the time, Gerald Lensen, insisted that it was designed incorrectly, because the River Channel Fault is 'tensional' (pulling apart) and not 'lateral' (slipping sideways). Needless to say, this fact has been kept quiet ever since.

Now, according to GNS scientists, the 'big one' is overdue along the Alpine Fault (bigger than the 7.8 Fiordland quake in July 2009). Meantime, the 6,500 measuring and monitoring stations quietly observe the landslide movements, reduced but not stopped, and visible silting up continues in the Kawarau Arm at an alarming rate estimated to be 1.46 million cubic metres per year, building up the reservoir bed profile by an estimated 1.85m annually.

The Decline of Large Hydro

In the 21st century, energy that is "renewable" is defined as energy from a source that is both naturally replenishing and environmentally safe and sustainable. The term “new” renewable energy has also been used to define the latest wave of renewable technologies that are truly environmentally sustainable.

By such standards, hydropower over 10 MW is no longer considered renewable because the negative impacts of large hydropower outweigh the so-called renewable benefits, which have inherent limitations.

In New Zealand, we are told that to maintain our present society and standard of living we need a minimum increase in power availability of 2.5% per annum (peak power), with 170 MW of new generation added each year. Based on this figure, we would need the equivalent of one Luggate dam (86 MW) every 6 months, or one Tuapeka dam (350 MW) every 25 months, or another Clyde dam (432 MW) every 29 months. Clearly, this is not a credible long-term solution.

World-wide, large hydropower declined in the 1990s because of mounting opposition that culminated in the World Commission on Dams report (2000), which acknowledged that large dams do not meet best practice guidelines in the water and energy sector. The global recession spurred more large dam projects, especially in developing countries, but the tide has turned and large hydro is again in decline as new renewable technologies sweep the world.

The intrinsic problems associated with large dams have long been glossed over. Hydroelectricity is often falsely promoted as cheap and reliable. While the operating costs of hydroelectric dams can be relatively low, their construction costs are extremely high, running into the billions of dollars for major projects. They are also prone to cost overruns. The WCD (World Commission on Dams, 2000) found that on average dams cost 56% more than forecast. And 55% of the hydroelectric projects studied by the WCD generated less power than planners promised.

New Zealand's Clyde dam is an obvious example of disastrous cost overruns. According to the public record, the 1982 winning bid from the joint venture of W. Williamson & Co. of Christchurch and Ed. Zublin AG of Stuttgart, was $102.6 million. Ten years later when the dam began producing power, the cost had climbed to $1.4 – 1.8 billion. Conversely, the planned generation of 612 MW had fallen to an actual capacity of 432 MW.

Typically, construction and mitigation costs are under-estimated, long-term costs are ignored, the value of the proposed dam and mitigation measures are inflated, while the value of the current and potential benefits from the existing environment are under-reported.

The proponents of large dams also invariably claim that large hydropower is "green" energy. However, the carbon footprint of a large-scale hydro project is anything but "green". A comparative study at the University of Auckland found that large hydro has a full-life carbon footprint that is 2.5 times larger than that of tidal energy.

A similar comparative study in the U.K. found that in terms of grams of CO2 equivalent per kWh of electricity generated, large hydro in the U.K. comes in with a carbon footprint 2 to 6 times larger than that of wind power. Specifically, large hydro has been measured at 10-30gCO2eq/kWh while wind has been measured at only 4.64gCO2eq/kWh, the lowest except for nuclear (Carbon Footprint of Electricity Generation, 2006).

It is easy to understand why large dams rate so poorly. For example, the Clyde dam contains 1 million cubic metres of concrete, equivalent to about 3 million tonnes. Manufacturing one tonne of cement requires 4.7 million BTU’s of energy, which is the amount contained in about 170 litres of oil or 190 kilograms of coal. Obviously, this combined with emissions from machinery involved in earthworks for foundations, roading, terrain forming, landslide mitigation, and through the loss of river corridor carbon sink forests or vegetation, adds up to an enormous carbon footprint.

There are over 54,000 large dams in the world, some 5,000 of which are over 50 years old. The typical design-life of such dams is 80 years, and an increasing number of old dams are being classified as high risk. It is a telling fact that more dams are being decommissioned than built in the U.S., but dam owners typically avoid decommissioning issues and try to evade the considerable costs associated with dam removal and river restoration. This scenario points to a looming dam safety crisis.

In the past, the benefits of large dams were viewed as outweighing their obvious short and long-term environmental impacts. That has changed.

Large hydropower once represented the epitome of 20th Century technology and a passport to prosperity, projecting a misguided belief that Nature could be controlled without consequences. In the 21st Century, we face a new reality, for which 20th Century energy solutions are unacceptable.

Roxburgh Dam Decommissioning?

The Roxburgh dam was commissioned in 1956, and it is New Zealand's oldest concrete gravity dam. Such dams have a design lifespan of 80-100 years, but the actual lifespan of a dam depends on the rate at which its reservoir fills with sediment. Assessing the remaining life of a dam and reservoir is complex, but reservoir flooding events indicate that time is running out.

When other issues are added to the picture, questions must be asked.

The Roxburgh dam - like the Clyde dam, has faultine and landslide issues that are potentially catastrophic (something which has been kept quiet). However, when the Roxburgh dam was built, there was minimal geotechnical investigation and mitigation undertaken, despite obvious evidence of major landslides in the Roxburgh Gorge, notably at Island Basin.

But reservoir sedimentation is the most problematic issue. In fact, within 15 years of the dam's commissioning, the dam's two low level sluice gates were inoperable, and since then the silt burden has filled much of the Roxburgh reservoir reaching back to Alexandra. In 1995, ECNZ estimated that 1.5 million cubic metres of silt had entered the Roxburgh reservoir every year before the Clyde dam was built, and that a total 50 million cubic metres of silt had accumulated in the reservoir, raising the bed profile 'considerably'. Attempts to 'flush' the silt have had little effect, and have not reversed this process. This is probably because of the 'Gates of the Gorge,' a narrow bottleneck just below Alexandra.

As a result, Alexandra has become flood-prone, and has installed flood defence walls along the river. But even these will not be high enough to prevent future flooding, because the riverbed will gradually keep rising. It was thought that by building the Clyde dam that this sedimentation problem would be largely solved, but some silt still gets through to continue choking the reservoir and river, and the Manuherikia River still contributes silt when it is high.

Efforts continue to "buy time" for the Roxburgh dam. More "flushing" will only move some of the sediment load further toward the dam. (Flushing has failed to remove sediment wherever it has been tried, including on the Colorado.) Physically removing millions of cubic metres of sediment is not practicable because of the costs involved. An interim measure is to remove some sediment from the Manuherikia confluence, and also from the Galloway area, but this does not address the major constriction at the 'Gates of the Gorge.'

The most desperate strategy is to raise the operating level of the Roxburgh reservoir, and this was done in 2009 when a rise of .6m was consented. While this allows water to reach the dam more easily, it also increases the risks associated with flooding events, both at Alexandra and the dam. In the life cycle of a dam, this is the "Russian roulette phase."

The dam owners and the Crown must face up to the fact that the Roxburgh dam and reservoir will not last forever, and that enormous risks are imposed on communities in the meantime. A feasibility study is needed to determine the most effective decommissioning and de-silting methodology. Where such dam removal projects have been undertaken overseas, the costs as a proportion of construction, range from 35% to 150%.

However, since there has been no provision for the ultimate decommissioning of the Roxburgh dam (typical of the hydropower industry), there is something of a head-in-the-sediment policy on this issue.

Questions should be asked, including the most difficult question of all ... when the time comes to decommission the dam, who will pay?
