Oilspill Update : 2325 tonnes of Rena waste processed so far

English: Waihi Beach, New Zealand

In Tauranga, the oil spill have had ‘gone’ public minds – I have seen public beaches previously ‘closed’ and now ‘back to normal’ . The waste and its impact, however, is still being dealt with ….  This from the Bay of Plenty Times | twitter.com/#!/LearnFromNature & twitter.com/#!/NAEE_UK

 

About 2325 tonnes of waste from the stricken cargo ship Rena has been processed since it ran aground off Tauranga in October, clean-up company Braemar Howells show.

Of that, 1870 tonnes has gone into landfills while 117 tonnes has been liquid waste, mostly blood from meat freezers.

Around 177 tonnes of the rubbish was collected from Waihi Beach and 77 tonnes from Matakana Island.

About 25 tonnes of milk powder has been collected and 120 containers have been processed by Braemar Howells.

The figures include waste which washed ashore and waste collected from the sea.

Braemar Howells spokeswoman Monique O’Connor said the company was prepared to deal with the same amount of waste again, but it was unclear how much more would be washed from the ship.

“A lot of that depends on what’s happening on board, which depends on what’s happening with weather conditions. It’s in the lap of the gods really.

“The clean-up is very much an ongoing operation. Initially it focused on the western Bay of Plenty because debris was focused nearer the Rena but it’s now a far greater area, it’s spread far to the north and south.

“We have vessels and people working constantly targeting different areas at different times.”

One of the aims this week was to recover containers holding timber which had washed up at two secluded beaches north of Waihi Beach, she said.

Beach Busters: Parking tickets a nightmare for the coast

From the New Zealand

The Herald on Sunday is campaigning to get all of New Zealand out on the beaches this summer, keeping them clean for our kids and our grandkids. Starting on Sunday 29 January at Orewa before theSummer Sunday festival, we’ll be out with our rubbish bags – and we want you and your family to join us.

 

You could be contributing to the mess on our beaches and not even know about it.

Recently 90 parking tickets or car registration dockets were picked up by volunteers cleaning up Rangitoto island.

We traced several of them back to their Auckland owners.

Sales rep Oliver Crisford, from Mount Eden, was astonished when a parking ticket issued in the CBD for his car in March last year was among them.

“I don’t remember getting that ticket and I assume it blew off my windscreen,” he said.

An infringement notice from December 2009 and issued in Grey Lynn to a ute registered to Auckland Council also showed up.

“We use a water resistant paper for infringement notices because previous paper-based ticket rolls melted in the rain and ended up being illegible mush,” a spokesman for Auckland Transport said.

Alexis Palacio, 19, from the North Shore, was amazed that a registration docket issued to his car in October, 2004, turned up on Rangitoto.

“I wasn’t even old enough to drive then so I assume I chucked it away when I bought the car at the start of 2010.”

Oilspill Update : Rena sinking inevitable

New Zealand Herald and sources

News that part of the Rena is sinking has been met with a sense of inevitability by local leaders, who say having the ship off the Astrolabe Reef could be a positive thing.

Most of the stern section of the MV Rena has slipped off the Astrolabe Reef this morning.

By 10.38am, the foremost part of the stern was still sticking up out of the water, with the rest – including the bridge – submerged.

The bow section remains unchanged in place on the reef.

Personnel from Maritime New Zealand and Svitzer Salvage have been airborne to monitor the slow progression of the stern into the sea since the vessel’s status began to change rapidly after 8.30am today.

Tauranga Mayor Stuart Crosby said he had been warned there was a “strong possibility” the stern would sink, so the news had not come as a shock.

“There is a small concern about whether it will settle on the sea bed and if this will create extra debris or if this will aid in the possible recovery of the Rena.”

Mr Crosby said his personal view was that the sinking of the stern was positive as it was off the reef.

“If it’s in reasonably deep water it could become a diving attraction. This is just another step in the Rena saga that would eventually happen. Maybe out of sight out of mind but this could be a positive thing for us.”

Tauranga MP Simon Bridges said there was a “sense of inevitability” that part of the Rena had sunk.

“Sadly I wasn’t surprised but in some way there is a silver lining because we now have a certainty about what’s going on because it will sink,” Mr Bridges said.

“We’re not left wondering what might go on and now this has provided clarity for Maritime NZ and the salvors.”

Ngati Ranginui chairman Hui Kakahu Kaue told the Bay of Plenty Timesyesterday there were spiritual, cultural, physical and emotional implications for iwi should part of the Rena sink.

“Physically, in terms of food we suffer, especially those in Motiti [Island]. There will be a long-term disadvantage and effect on them.”

Steve Penn, of the Waikato and Bay of Plenty Marine Recreational Fishers Association, said most fishers had accepted it was likely that the ship would sink.

He said he not believe the sunken hull would have a negative effect on the environment.

He did not think it would be much different to incidents in which battleships were deliberately sunk for fishing and diving purposes.

“Probably a lot of fishermen will say `great, a little bit more hapuka’. It could be a good thing,” Mr Penn said.

“Depending on the depth, it will probably be an opportunity for divers.”

The ship would inevitably break down over the years.

Russ Hawkins of Fat Boy Charters said there could be some positive outcomes from the stern being sunk.

The eventual outcome could be of huge benefit for the local marine industry.

“Especially at this time of year. This is a special time of year, where you get the whole food chain out there from kahawai to trevally, kingfish, and marlin and sharks,” Mr Hawkins said.

The sunken Rena could provide a boost to tourism, he said.

Hope wreck could be used for diving

Papamoa Surf Life Saving Club head lifeguard Shaun Smith, who has been looking at the Rena everyday since it ran aground, said the broken part of the stern was still sticking out at about a 45-degree angle.

“The bit of the front half of the boat is still sitting there perfectly and the second half has definitely sunk, but there’s a big hunk of it still sticking out of the water.”

With the wind blowing directly onto the beach, Mr Smith was concerned further containers and debris could come ashore.

There had been earlier discussion over whether the stern would be left where it was or brought back to the surface and removed if it sank.

Green Party MP and oceans spokesman Gareth Hughes said people would have the opportunity to dive to the wreck if it was left where it was.

In its current position, the stern would sink to a depth of about 90m, meaning divers would be able to reach it. Most divers can go to only half that depth.

“Although it would have been ideal if it the stern could have been towed in and cleaned first, the salvors said it wasn’t safe to bring it in. Safety has to be paramount and we have to defer to the experts,” he said.

Sinking closely monitored

Maritime New Zealand confirmed this morning there has been change in the position of the ship’s stern and they are closely monitoring the situation.

A Maritime spokeperson said the accommodation section of the Rena was already completely underwater.

There was no one on board.

“The accommodation section, the white part that sticks up, is beneath the water. The front of the aft part of the ship is still above water and it’s still upright at this stage,” the spokeswoman said.

The aft section is the larger part of the stricken cargo ship, which ran aground on the Astrolabe reef off Tauranga in October.

Salvors noticed the stern moving on the reef about 9am.

MNZ staff and salvors Svitzer have been airborne to monitor the slow progression of the aft section into the sea since the vessel’s status began to change rapidly after 8.30am.

Information about any further release of oil, debris or containers from the Rena would be released as soon as it was available, MNZ said.

Transport Minister Gerry Brownlee is heading to Tauranga and will hold a press conference at 3pm.

Papamoa Surf Life Saving Club head lifeguard Shaun Smith, who has been looking at the Rena everyday since it ran aground, said the broken part of the stern was still sticking out at about a 45-degree angle.

“The bit of the front half of the boat is still sitting there perfectly and the second half has definitely sunk, but there’s a big hunk of it still sticking out of the water.”

With the wind blowing directly onto the beach, Mr Smith was concerned further containers and debris could come ashore.

There had been earlier discussion over whether the stern would be left where it was or brought back to the surface and removed if it sank.

Green Party MP and oceans spokesman Gareth Hughes said people would have the opportunity to dive to the wreck if it was left where it was.

In its current position, the stern would sink to a depth of about 90m, meaning divers would be able to reach it. Most divers can go to only half that depth.

“Although it would have been ideal if it the stern could have been towed in and cleaned first, the salvors said it wasn’t safe to bring it in. Safety has to be paramount and we have to defer to the experts,” he said.

Meanwhile containers and debris from the wrecked Rena could drift as far north as holiday hotspot Whitianga and beachgoers have been warned to look out for timber and other dangerous material that could be hidden in the surf.

Mt Maunganui and Papamoa were yesterday spared the worst of the Rena breaking in two, but several freight containers and hundreds of 20kg bags of milk powder washed up on Waihi Beach – nearly 60km away.

There were also reports of looting of the stranded goods, tyres beaching at Matakana Island and a 3km sheen of oil stretching from the ship which is close to sinking since crashing into the Astrolabe Reef on October 5.

An observation flight this morning found more debris has been found around the Rena, including bits of plastic and wood.

Waihi Beach residents and holidaymakers awoke to fine weather yesterday and a number of containers and hundreds of bags of milk powder that littered the coast for hundreds of metres.

Gerard North, visiting from Dunedin, was looking forward to his first swim of “a really crappy summer” before fire firefighters cleared him and dozens of others from the popular beach.

“It’s the best day we’ve had in ages and this is what we get – milk powder, containers and no beach,” he said.

“It’s bad, the milk powder stinks … it’s been a really crappy summer.”

The beach was closed for some hours yesterday morning as decontamination crews converged and police reported receiving calls about a group taking bags of what appeared to be milk powder.

Twelve containers have now washed up on Waihi Beach, and another 25 have made landfall at Matakana Island.

Sergeant Dave Litton of Waihi police urged people not to take anything from the containers. He appealed to the group who took the goods to return them to the beach, where they can be managed by the clean-up crews.

Waihi Beach was reopened in the afternoon but people were cautioned about swimming and the area around containers and debris will be restricted if necessary.

Claudine Sharp, of recovery specialist Braemar Howells, said initial estimates of up to 300 containers being washed overboard on Saturday night were incorrect and based on photographs it was now calculated that about 150 were drifting in the sea.

By yesterday afternoon, 12 containers had come ashore between Waihi Beach, Bowentown and Matakana Island with timber, recycled paper and polypropylene ropes among the cargo.

A further 20 containers with the toxic substance cryolite had also spilled overboard but were likely to be in water surrounding the ship, because of the heavy weight of the cargo.

Cryolite is a by-product of the aluminium smelting process, which is considered low risk unless ingested or inhaled directly in its dry powdered form.

Experts say the cryolite on board Rena is low risk, given that it is only slightly soluble in water, and is expected to dissolve slowly.

Ms Sharp said the recovery teams were battling against the weather, but based on trajectory models debris would continue to wash up around Waihi Beach and possibly as far as Whitianga, about 160km north in the Coromandel Peninsula.

The Herald understands some debris was spotted off Whiritoa Beach, south of Whangamata yesterday.

“Our main plan for recovery is through our marine assets. We want to retain this through the ocean … we prefer not to have them come ashore,” said Ms Sharp.

“We are trying to trawl the debris where we can and reclaim the debris and try to keep the containers off the land.”

Transport Minister Gerry Brownlee said the debris in the wrong circumstances could be difficult to deal with.

“Imagine loose lengths of timber sloshing about inside the surf alongside large sheets of plywood, it could be quite damaging for people who get in the road of it.

“So the advice that people should stay away from that debris, I think is advice that should be well-heeded.”

Maritime New Zealand also reported small oil spills at Matakana Island, Mount Maunganui and Leisure Island after earlier reports of a 3km long sheen of oil that was about 10 metres wide leaking from the ship.

Maritime New Zealand salvage expert Jon Watson said there was still oil trapped in the vessel but authorities did not know how much and could not measure it.

Mr Watson said the Rena’s stern section, which has listed to starboard by a further one to two degrees, was pivoting around a particular point on the Astrolabe Reef.

He said it was unclear how far it was from the reef’s edge or what it would take to knock it off .

“We don’t know what strength that point is on the reef. It may be a small bit of movement may knock it over.”

Mr Watson said the ship will still be salvaged if it sinks, along with the containers that have sunk.

Maritime New Zealand salvage unit manager Dave Billington said salvors landed on the front section of the ship on Sunday but could not board the stern section as the salvage master deemed it too dangerous.

It was “highly likely” the remaining containers on the vessel would spill if the ship sank.

“The hatch covers are removed, if the ship does sink and turn upside down the containers will discharge from the ship,” he said.

Maritime New Zealand national on-scene commander Alex Van Wijngaarden said there were reports of five oiled penguins, but investigations showed that just two were affected.

Quake Update : Magnitude 4.7 quake strikes Christchurch, New Zealand

Pegasus Bay, South Island, New Zealand

Image via Wikipedia

From Stuff.co.nz

A magnitude-4.7 earthquake hit Christchurch at 8.04pm, hours after a magnitude-5 quake interrupted a special briefing on aftershocks.

The earthquake was centred 20km east of Christchurch at a depth of 11km.

The magnitude-5 quake, which struck at 2.20 this afternoon, was centred 5 kilometres underground and 10km north-east of Christchurch.

Only a minute before it struck, there was also a magnitude-3.5 shake, which was at a depth of 10km and centred 20km east of the city.

The briefing by GNS scientists to councillors, MPs, and the media, was called following concerns about the frequency and magnitude of aftershocks centred on Pegasus Bay since December 23.

The second bigger quake struck about an hour after scientists told the briefing that the city would definitely be hit by another magnitude 5.0 tremor.

Both this afternoon’s quakes were centred in the Pegasus Bay area.

Twitter users said the magnitude-5 shake was a “long wobble” and “lengthy shake”.

QUAKES TO DECAY OVER DECADES

Kelvin Berryman of GNS Science said the sequence of quakes will decay over decades rather than years.

“Christchurch city has had a lot of quake activity. A lot of the stress must have been released in the city area, but around Canterbury there may well be an ongoing sequence over a period of a few decades.”

Berryman said there are still some imperceptible remnants of the Inangahua quakes in 1968.

“They are still there, but they are not detectable or stopping people from getting on with their lives. We are getting into a period that is damaging to people’s confidence. It is mental rather than physical.”

“These are very upsetting events rather than dangerous or damaging.”

Berryman stressed the sequence would decay over the decades and become imperceptible.

“It decays away to something that is imperceptible”

“It is not a one to five year period, it is a period of many decades.”

TSUNAMI WARNING SYSTEM

Earlier,  mayor Bob Parker told the briefing that a tsunami warning system was likely to be in place in Christchurch by the end of June.

The audience was told that a probability of a magnitude-7.0 quake striking Christchurch and triggering a tsunami was “very low” but further liquefaction remained a possibility.

Berryman said quakes of a magnitude-6 did not produce tsunamis of any significance.

But if a quake of magnitude 7.0 hit, “don’t wait to be told by Civil Defence to move off the beach”. Berryman said those living in seaside suburbs should “self evacuate”.

However, a tsunami was more likely to be triggered by a quake off the coast of South America, and New Zealand would have 12 hours warning of its arrival.

Berryman said the recent spate of quakes was “very rare”.

However, the magnitude-6.0 which struck on December 23 was close to that which had been forecast.

GNS had forecast a 50-50 probability of a mag-5.0-5.9 striking the region. ” So this was at or a little bit above what we had forecast.”

“The probability of a 7 is low. . . it’s not zero but it’s very low,” said Berryman.

Berryman said the quakes at a depth of 8 to 10km were in “very old rock” which had broken up into many faults.

The recent spate of quakes centred off the Christchurch coast were reaching towards the relatively large Kaiapoi Fault “but they’re not there yet”.

The Kaiapoi Fault may be up to 30km long, and potentially capable of producing a magnitude-7.0 quake but the current earthquakes were not “anywhere near” it.

“Our expectation is [the current sequence of quakes] will go into the same decay sequence as we saw post-February and post-June.

“There is almost certainly still a 5.0 out there and we would guess quite a few 4′s and 3s on a daily basis,” said Berryman.

“We are progressing into a period where quakes are not damaging but they can affect people mentally.”

LIQUEFACTION RISK REMAINS

Berryman said if a magnitude-6 quake, close to the city, struck then liquefaction was likely. “5s don’t really produce significant liquefaction.”

Larger quakes further away, such as a magnitude-7.0 in Hanmer or a magnitude-8.0 on the Alpine Fault may also cause liquefaction in Christchurch.

The audience was told that the amount of liquefaction silt spewed out of the ground meant some parts of Christchurch were now “hundreds of millimetres” lower than they were two years ago.

Research seismologist Stephen Bannister said the ground accelerations of the recent earthquakes were less than the city had suffered early last year.

In the February quake ground accelerations of more than 2G were felt in many places, including Heathcote Valley.

“As we move through the June event … we still got high horizontal acceleration in some areas, and lower acceleration in the city centre,” said Bannister.

“As we move to the current events in December, we are having much lower acceleration through the city.”

More than 9500 shakes have hit Canterbury since the magnitude-7.1 quake on September 4, 2010.

Councillor Helen Broughton asked the scientists if all 9600 shakes were “aftershocks” or if three or four could be classified as earthquakes.

Bannister said the thousands of events could all be be described as “aftershocks” to the September 4 earthquake. This Darfield earthquake had altered the stress field across the greater Canterbury region .

Mayor Bob Parker said earlier this week said he was keen to provide information on the “unusual” quake sequence.

“People are asking more and more questions around, ‘What is going on?”‘ he said.

“People have said to me that they feel like they’re not getting the full story.

“I don’t believe that is the case, but I also believe that it’s important for our scientists to front up for us to have a chance to get a full briefing as a community.”
