#BALTIMORE WHALE - Nine weeks after the tragic demise of the Baltimore Harbour fin whale, its carcass is still afloat off West Cork, creating a “rancid oil slick” in a special conservation area, according to a local resident.

Tom McCarthy contacted Afloat.ie with the above image of the 65ft whale carcass, which was towed out to the grey seal breeding ground off the Carthys Islands in Roaringwater Bay and has apparently been left to rot.

“It has been left here since the middle of August to decay,” says Tom. “The rancid oil slick is clearly visible and extends for over 1km on relatively still days, the smell is horrendous."

As previously reported on Afloat.ie, plans were afoot to sink the fin whale carcass that was trapped in Baltimore Harbour in mid-August and endured a harrowing few days trapped in Baltimore Harbour before it died from what's presumed to be a combination of illness and injury.

Tom McCarthy claims that the National Parks and Wildlife Service (NPWS) has washed its hands of the situation, considering the enormous marine mammal carcass to be a natural occurrence "even though the animal beached and died several miles [away and] was wrapped in a net and towed to its final resting position".

The location is in a Special Area of Conservation - yet according to Tom, no risk assessment appears to have been carried out beforehand.

"Ten minutes on the internet would show that whales are perhaps the most contaminated animals in the world," he says. "Their blubber is contaminated with persistent organic compounds such as PCBs, DDT, dioxins, etc and the internal organs such as the liver and kidneys are 'high', 'very high' or 'staggeringly high' in mercury, cadmium, chromium, etc.

"Some beached whales are found to be so contaminated the whale itself has to be considered as hazardous waste and disposed of as such."

Tom notes that the area is fished extensively for shrimp, crab, lobster and pollock, and that the rotting carcass is in close proximity to several mussel farms.

"It seems inevitable that as the whale continues to decay and is eaten whatever contaminants were present prior to death will re-enter the food chain."

He compares the current situation to a similar whale carcass disposal in Sligo last year, where the flesh was cut off and sent for incineration while the bones were marked for later skeletal recreation and sent for composting.

Regarding the West Cork whale carcass, Tom says: "Some estimates say it will take three years for the whale to completely decay."

Tom adds that he has been in contact with Cork County Council and hopes to hear on Monday about plans for a more appropriate method of disposal for the whale carcass.

#GALWAY BAY - Galway residents are voicing fears over pollution in Galway Bay due to alleged increase in outfalls from the city's sewage system.

As Galway News reports, locals in the Claddagh area spotted a discharge of raw sewage into the Claddagh Basin in July, which was confirmed by City Councillor Catherine Connolly to be an outfall.

Such releases are triggered automatically, like a safety valve, in emergency circumstances, such as after heavy rainfall which backs up the system.

Cllr Connolly has expressed her concern over an increase in the number of such releases over recent months, and their potential contribution to the degradation of water quality in the area - especially following the temporary closure of Grattan Beach in Salthill last month due to E.coli contamination.

She has also called for a report from the council on the difficulties experiences at the Mutton Island water treatment plant resulting from the inflow of grease and fats into the system from hotels and restaurants.

#FISHING - Environmental campaigners have lambasted the IFA's claims of an "inexplicable delay" in the State's processing of licence applications for fish farms.

In a letter to The Irish Times yesterday, Tony Lowes of Friends of the Irish Environment says that the delay – to allow for proper environmental studies to be conducted – "has been explained again and again" by Minister for the Marine Simon Coveney.

He was responding to a letter last Friday by Richie Flynn of IFA Aquaculture, who highlighted the "suffering" of coastal communities as a result of processes that "hamper development and delay investment in the hundreds of companies involved in farming salmon, oysters, mussels, trout and other species".

Lowes writes in counter that salmon farming "is a highly polluting industry", and that discharge of nitrogen and phosphorous from aquaculture facilities "can fuel toxic algae blooms, which have cost the shellfish industry dear".

He claims that the proposed salmon farm in Bantry Bay in West Cork would have a nitrogen and phosphorous discharge "equivalent to the sewage of a town 10 times the size of Bantry".

Lowes also alleges that the deep-sea "super salmon" farm in Galway Bay - the licence application for which is undergoing statutory consultation till 2 October - would produce the equivalent effluent of a city more than double the size of Galway.

In addition, he makes reference to the threat to native salmon in Irish rivers through sea lice infestations.

"The EU habitats directive requires baseline studies and environmental impact statements," writes Lowes. "Licensees can be granted only if the project will not have adverse impacts on protected species and habitats."

#COASTAL NOTES - The Irish Times reports that Balbriggan Beach was reopened for swimming yesterday 31 August after the latest in a string of E.coli scares around the Irish coast.

The beach at the north Co Dublin coastal town was closed to bathers after a pumping station malfunction caused raw sewage to be pumped into the sea for up to 24 hours earlier this week.

E.coli levels were subsequently recorded at five times the maximum EU safety limit, and as much as 100 times the Blue Flag standard for European beaches.

The incident raised concerns among campaigners opposed to the proposed new water treatment 'super plant' for Fingal.

As previously reported on Afloat.ie, worries have been expressed by locals in the towns of Skerries, Loughskinny and Rush about the effects of the planned outfall pipe in their area.

The Balbriggan swimming ban marked the second beach closure in north Dublin during August, after the waters at Rush South were found to be contaminated with E.coli over the bank holiday weekend.

A bathing ban was also imposed on seven beaches in Cork last month due to high levels of the bacteria, while a breach of safe levels at Salthill in Galway last week caused concern ahead of tomorrow's Ironman 70.3 triathlon.

#COASTAL NOTES - The bathing ban imposed last week on seven Cork coastal beaches has been lifted, according to RTÉ News.

As previously reported on Afloat.ie, the seven beaches had been closed to swimming over concerns at elevated E.coli levels in the water, resulting from water runoff after the recent heavy rainfall in the county.

Cork County Council took the decision to lift restrictions after tests this week showed E.coli levels had "significantly descreaed" below the EU mandatory safety level.

The seven affected beaches included three in the Youghal area. Redbarn at Youghal joins Garretsown near Kinsale and Garryvoe in the beaches that can fly their Blue Flags once more.

#COASTGUARD - The Irish Coast Guard is ill-prepared to respond to any major pollution incident off our coastline, according to a report commissioned by the Government.

As Lorna Siggins writes in The Irish Times on Friday, the report identified weaknesses in communication within the coastguard and in the training of volunteer crews, as well as deficiencies in the Marine Survey Office.

Minister for Transport Leo Varadkar, whose office commissioned the 'value for money' studies, said he would begin an action plan due in October to deal with such issues, which may require "tough decisions" - including the closure of a coastguard radio station at Malin or Valentia.

The studies by Fisher Associates highlighted the lack of a dedicated polluton control team within the coastguard, despite staff having "sufficient knowledge to respond".

Auditing of various pollution response plans was also found to be lax, while problems were also identified in management and training of the coastguard's 1,000 volunteers.

#INLAND WATERWAYS - The Tyrone Times reports that Clogher and District Angling Club has been awarded £1,000 (€1,196) by the Northern Ireland Environment Agency (NIEA) for an environmental project with local schools.

The Water Environment Community Awards recognised the club for its work with St McCartan's Primary School in Clogher and Augher Central Primary School to "investigate the signs and impact of pollution in the River Blackwater" over the coming months.

“Clogher and District Angling Club have demonstrated their commitment to protecting and improving their local water environment," said the NIEA's Dave Foster.

"I hope that their efforts over the next few months will inspire others to do their bit too and I would urge people to follow these projects and share what they see.”

#NEWS UPDATE - The Irish Petroleum Industry Association (IPIA) has proposed a suite of measures aimed at tackling the problem of illegal diesel washing in Ireland.

In a statement, the industry body for Ireland's fuel industry says that the practice is costing the Exchequer as much as €155 million annually in lost fuel duty.

"While other jurisdictions have to tackle this sort of fraud, the sheer scale of criminal washing of diesel is a particularly Irish disease," it said.

The IPIA's recommendations include the introduction of "a strong regulatory regime" to control the sale of rebated fuel, a new market for off-road diesel that is harder to disguise or remove, the closure of unlicenced filling stations, and a "radical overhaul" of the currently "absurd" penalties for offending retailers.

The Irish Angling Development Alliance (IADA) has fully backed the IPIA's proposals, citing the dangers of toxic waste byproducts from diesel washing operations.

"This toxic waste has been dumped illegally across the country, where it can enter the water table, not only seriously polluting water courses but also clean drinking water supplies."

#INLAND WATERWAYS - Officials at the Northern Ireland Environment Agency (NIEA) are attempting to find the source of a pollutant that resulted in a fish kill on the Threemilewater river in recent weeks.

The Newtownabbey Times reports that more than 120 trout and salmon parr have been found dead on the short stretch of river between Mossley Mill and Doagh Road in Newtownabbey, Co Antrim.

John Webster of the Threemilewater Conservation and Angling Association speculated that the pollutant may have entered the water from any of a number of pipes that flow into the waterway near the railway line at Mossley Mill.

He described the fish kill as "an absolute diasaster", especially coming as it did at the opening of the fishing season on 1 March.

#LARNE LOUGH - Larne Council has looked into the concerns of local residents over a proposed £250 million (€300 million) natural gas plant at Larne Lough, the Larne Times reports.

Islandmagee Storage Limited (IMSL) has applied for planning permission for a 500 million cubic metre natural gas storage facility in Permian salt beds almost a mile beneath the lough, which is claimed would satisfy the North's peak demand for gas for over 60 days.

But locals have spoken out with their fears over noise levels, health and safety, pollution and the potential effect on tourism in the area.

Larne Council’s environmental health department carried out its own research into the proposed facility, taking these concerns into consideration.

It found that there was "no huge issue in terms of noise levels" where similar facilities are established throughout the UK and that the effect on tourism would be negligable.

However the department was “not yet happy” with data supplied by IMSL regarding noise levels and would be seeking more detailed information.

Ireland's Offshore Renewable Energy

Because of Ireland's location at the Atlantic edge of the EU, it has more offshore energy potential than most other countries in Europe. The conditions are suitable for the development of the full range of current offshore renewable energy technologies.

Offshore Renewable Energy FAQs

Offshore renewable energy draws on the natural energy provided by wind, wave and tide to convert it into electricity for industry and domestic consumption.

Offshore wind is the most advanced technology, using fixed wind turbines in coastal areas, while floating wind is a developing technology more suited to deeper water. In 2018, offshore wind provided a tiny fraction of global electricity supply, but it is set to expand strongly in the coming decades into a USD 1 trillion business, according to the International Energy Agency (IEA). It says that turbines are growing in size and in power capacity, which in turn is "delivering major performance and cost improvements for offshore wind farms".

The global offshore wind market grew nearly 30% per year between 2010 and 2018, according to the IEA, due to rapid technology improvements, It calculated that about 150 new offshore wind projects are in active development around the world. Europe in particular has fostered the technology's development, led by Britain, Germany and Denmark, but China added more capacity than any other country in 2018.

A report for the Irish Wind Energy Assocation (IWEA) by the Carbon Trust – a British government-backed limited company established to accelerate Britain's move to a low carbon economy - says there are currently 14 fixed-bottom wind energy projects, four floating wind projects and one project that has yet to choose a technology at some stage of development in Irish waters. Some of these projects are aiming to build before 2030 to contribute to the 5GW target set by the Irish government, and others are expected to build after 2030. These projects have to secure planning permission, obtain a grid connection and also be successful in a competitive auction in the Renewable Electricity Support Scheme (RESS).

The electricity generated by each turbine is collected by an offshore electricity substation located within the wind farm. Seabed cables connect the offshore substation to an onshore substation on the coast. These cables transport the electricity to land from where it will be used to power homes, farms and businesses around Ireland. The offshore developer works with EirGrid, which operates the national grid, to identify how best to do this and where exactly on the grid the project should connect.

The new Marine Planning and Development Management Bill will create a new streamlined system for planning permission for activity or infrastructure in Irish waters or on the seabed, including offshore wind farms. It is due to be published before the end of 2020 and enacted in 2021.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE. Is there scope for community involvement in offshore wind? The IWEA says that from the early stages of a project, the wind farm developer "should be engaging with the local community to inform them about the project, answer their questions and listen to their concerns". It says this provides the community with "the opportunity to work with the developer to help shape the final layout and design of the project". Listening to fishing industry concerns, and how fishermen may be affected by survey works, construction and eventual operation of a project is "of particular concern to developers", the IWEA says. It says there will also be a community benefit fund put in place for each project. It says the final details of this will be addressed in the design of the RESS (see below) for offshore wind but it has the potential to be "tens of millions of euro over the 15 years of the RESS contract". The Government is also considering the possibility that communities will be enabled to invest in offshore wind farms though there is "no clarity yet on how this would work", the IWEA says.

Based on current plans, it would amount to around 12 GW of offshore wind energy. However, the IWEA points out that is unlikely that all of the projects planned will be completed. The industry says there is even more significant potential for floating offshore wind off Ireland's west coast and the Programme for Government contains a commitment to develop a long-term plan for at least 30 GW of floating offshore wind in our deeper waters.

There are many different models of turbines. The larger a turbine, the more efficient it is in producing electricity at a good price. In choosing a turbine model the developer will be conscious of this ,but also has to be aware the impact of the turbine on the environment, marine life, biodiversity and visual impact. As a broad rule an offshore wind turbine will have a tip-height of between 165m and 215m tall. However, turbine technology is evolving at a rapid rate with larger more efficient turbines anticipated on the market in the coming years.

 

The Renewable Electricity Support Scheme is designed to support the development of renewable energy projects in Ireland. Under the scheme wind farms and solar farms compete against each other in an auction with the projects which offer power at the lowest price awarded contracts. These contracts provide them with a guaranteed price for their power for 15 years. If they obtain a better price for their electricity on the wholesale market they must return the difference to the consumer.

Yes. The first auction for offshore renewable energy projects is expected to take place in late 2021.

Cost is one difference, and technology is another. Floating wind farm technology is relatively new, but allows use of deeper water. Ireland's 50-metre contour line is the limit for traditional bottom-fixed wind farms, and it is also very close to population centres, which makes visibility of large turbines an issue - hence the attraction of floating structures Do offshore wind farms pose a navigational hazard to shipping? Inshore fishermen do have valid concerns. One of the first steps in identifying a site as a potential location for an offshore wind farm is to identify and assess the level of existing marine activity in the area and this particularly includes shipping. The National Marine Planning Framework aims to create, for the first time, a plan to balance the various kinds of offshore activity with the protection of the Irish marine environment. This is expected to be published before the end of 2020, and will set out clearly where is suitable for offshore renewable energy development and where it is not - due, for example, to shipping movements and safe navigation.

YEnvironmental organisations are concerned about the impact of turbines on bird populations, particularly migrating birds. A Danish scientific study published in 2019 found evidence that larger birds were tending to avoid turbine blades, but said it didn't have sufficient evidence for smaller birds – and cautioned that the cumulative effect of farms could still have an impact on bird movements. A full environmental impact assessment has to be carried out before a developer can apply for planning permission to develop an offshore wind farm. This would include desk-based studies as well as extensive surveys of the population and movements of birds and marine mammals, as well as fish and seabed habitats. If a potential environmental impact is identified the developer must, as part of the planning application, show how the project will be designed in such a way as to avoid the impact or to mitigate against it.

A typical 500 MW offshore wind farm would require an operations and maintenance base which would be on the nearby coast. Such a project would generally create between 80-100 fulltime jobs, according to the IWEA. There would also be a substantial increase to in-direct employment and associated socio-economic benefit to the surrounding area where the operation and maintenance hub is located.

The recent Carbon Trust report for the IWEA, entitled Harnessing our potential, identified significant skills shortages for offshore wind in Ireland across the areas of engineering financial services and logistics. The IWEA says that as Ireland is a relatively new entrant to the offshore wind market, there are "opportunities to develop and implement strategies to address the skills shortages for delivering offshore wind and for Ireland to be a net exporter of human capital and skills to the highly competitive global offshore wind supply chain". Offshore wind requires a diverse workforce with jobs in both transferable (for example from the oil and gas sector) and specialist disciplines across apprenticeships and higher education. IWEA have a training network called the Green Tech Skillnet that facilitates training and networking opportunities in the renewable energy sector.

It is expected that developing the 3.5 GW of offshore wind energy identified in the Government's Climate Action Plan would create around 2,500 jobs in construction and development and around 700 permanent operations and maintenance jobs. The Programme for Government published in 2020 has an enhanced target of 5 GW of offshore wind which would create even more employment. The industry says that in the initial stages, the development of offshore wind energy would create employment in conducting environmental surveys, community engagement and development applications for planning. As a site moves to construction, people with backgrounds in various types of engineering, marine construction and marine transport would be recruited. Once the site is up and running , a project requires a team of turbine technicians, engineers and administrators to ensure the wind farm is fully and properly maintained, as well as crew for the crew transfer vessels transporting workers from shore to the turbines.

The IEA says that today's offshore wind market "doesn't even come close to tapping the full potential – with high-quality resources available in most major markets". It estimates that offshore wind has the potential to generate more than 420 000 Terawatt hours per year (TWh/yr) worldwide – as in more than 18 times the current global electricity demand. One Terawatt is 114 megawatts, and to put it in context, Scotland it has a population a little over 5 million and requires 25 TWh/yr of electrical energy.

Not as advanced as wind, with anchoring a big challenge – given that the most effective wave energy has to be in the most energetic locations, such as the Irish west coast. Britain, Ireland and Portugal are regarded as most advanced in developing wave energy technology. The prize is significant, the industry says, as there are forecasts that varying between 4000TWh/yr to 29500TWh/yr. Europe consumes around 3000TWh/year.

The industry has two main umbrella organisations – the Irish Wind Energy Association, which represents both onshore and offshore wind, and the Marine Renewables Industry Association, which focuses on all types of renewable in the marine environment.
