After the floods = before the floods

Last winter saw some of the most dramatic floods in Ireland’s history. The rainy season is about to start. Will we see half the country under water again? We don’t know what the weather will be like. We do know, however, that everything else is much the same as last year.

It takes time to build or reinforce flood defenses. Monies have been allocated to the OPW to do that, and we’ll see the results in years to come. Other matters should take less time, but our dear leaders have been otherwise occupied.

An Oireachtas committee concluded that too many agencies were part-responsible for flood management. They still are. The same committee argue that a single minister should be in charge in case of an emergency. He is still not. Last winter, it was not clear who should call in the army and when. It still is not.

One of last year’s problems was that there was no early warning system. There is still no national one at either floodmaps or flooding, and the county councils do not seem to have put anything in place either. Hydrometric data are still incomplete and out of date. Last year, ESB filled up its reservoirs just before the rainy season. Did they do so again? The latest data I could find on the river Lee are from 2008, and do not cover the reservoirs.

The ESB is still in charge of these reservoirs. In last year’s panic over potential dam failure, the dam operators did not warn the people in Cork. Do the authorities now have automatic access to data on water levels and releases? If they do, they have kept silent about it.

So, Ireland is still as vulnerable to flooding as it was a year ago. Let’s hope it won’t rain as much.

Environmental regulation and enforcement

Two weeks ago, the Irish Times reported that MoneyPoint regularly breached its IPPC license but failed to inform the EPA. I was waiting for a follow-up article, like “Plant Closed, Chief Engineer Jailed, Company Fined”, but then I realized that I’m in Ireland still.

If a coal-fired boiler runs in steady state, it emits little more than water vapour (white smoke) and carbon dioxide (invisible). However, if it is starting up or winding down, combustion is incomplete and smoke turns black. Black smoke contains a mix of chemicals which not only twist your tongue but also cause respiratory problems, cancer, degenerative diseases, and other mayhem. Such emissions are therefore strictly regulated, and rightly so.

The report and the lack of follow-up is disconcerting for a number of reasons. First, the ESB knew but did not tell the EPA. Second, the EPA got into action after complaints by locals. This does not help against nightly emissions or invisible ones. Third, there were two more incidents after the ESB was audited (and presumably warned) by the EPA. Fourth, there is no sign of remedial or punitive action.

(There is a side issue. Power plants should not do this. The boilers are either in much worse condition than their age suggests, or the engineers in charge are not doing their job as they should.)

Regulation is only as strong as its enforcement. For a plant the size of MoneyPoint, the EPA (and the public) should be able to monitor emissions in real time. We should not rely on voluntary disclosure or complaints. The EPA should have the right to intervene in the running of the plant, and shut it down if necessary. The owners and operators of the plant do not have the right incentives.

IPPC licenses were put in place to please Brussels, but they in fact protect our health and environment.

Luas needs joined-up thinking

A guest post by Donal Ó Brolcáin

The property-induced economic crisis has given us an opportunity to scrap Metro North and the proposed Dart Interconnector, and instead expand the Luas system in Dublin. Within the next few weeks, the Railway Procurement Agency (RPA) will open the Luas Green line extension to Cherrywood. This includes two fully equipped stations that will not be used. Recently, Iarnrod Eireann said it will not open a newly built station on the Kildare line. In both cases, the reason is that expected property development did not take place.

Metro North and the Interconnector are also predicated on development assumptions that no longer hold. Meanwhile, the government has dropped plans to link the two existing Luas lines for passenger services. This perpetuates the folly of the decision made in 1998 to build two separate Luas lines.

To meet the aims of government transport policy – to ensure the provision of a well-functioning, integrated public transport system that enhances competitiveness and contributes to social cohesion – I propose an integrated Luas, which would create an on-street loop around the central business district; access Dublin airport from all parts of the network, including a link to Dart; and fill the transport void in north Dublin with three Luas lines, all on the surface and cheaper per kilometre than Metro North.

Luas cannot be a network without integrating the Green and Red lines. This means a full interchange at the O’Connell Street-Abbey Street junction. This is no more radical a suggestion than the RPA-Iarnrod Eireann proposal to uproot St Stephen’s Green as part of their plans for two lines (Metro North, Dart Interconnector) underneath that part of Dublin.

Integrating the Green and Red lines needs two tracks on-street from Stephen’s Green to Broadstone, as RPA proposes. It would transfer to the unused line that joins the Western line (Maynooth, with the new Dunboyne line) at Broombridge.

Last Friday, An Bord Pleanála was due to hold a preliminary hearing on RPA’s application to build another Luas line, one that will not connect the existing lines for passenger services. The plan includes a bridge across the Liffey, joining Marlborough Street and Hawkins Street. This is silly, as it ignores the Samuel Beckett bridge, designed to take Luas vehicles. Why build yet another bridge that does not extend the Luas catchment area? Such a proposal goes against the notion of cost-effective improvement of public transport in the built-up parts of the capital.

The Docklands loop that I am proposing would use the Samuel Beckett bridge to integrate this new city quarter. Running on-street, it would connect the catchment areas of the Green line (Sandyford- Cherrywood) to the docklands, linking up the newly opened National Conference Centre, O2, Busaras, Connolly station and the Abbey theatre. It would connect the Red line (Tallaght-O2) to the south docklands, allowing easier access to the Grand Canal theatre, Shelbourne Park, the Aviva stadium, the Eye and Ear Hospital and National Concert Hall. It would require a new Dart interchange at Barrow Street on the southside, complementing Connolly Station on the northside.

The North Dublin loop would start from the joined-up Luas lines in O’Connell Street, run up Dorset Street, Drumcondra, Whitehall, Collins Avenue/DCU to Ballymun, onto the airport and back through Finglas to join the extended Green line at Broombridge. The airport can be linked to the Dart at Clongriffin, with a Luas line taking in Coolock, Beaumont Hospital and the North Fringe. That would put Dublin airport on a loop connecting it to the central business district from two directions. The airport can be also linked to the Dart at Clongriffin, with a Luas line taking in Coolock, Beaumont Hospital and the North Fringe.

Our governing classes love grand gestures, usually involving the feuding public-sector baronies of CIE companies, the RPA, National Roads Authority, local authorities, government departments and the newly created National Transport Authority. They refuse to learn from the mistakes made when railways were first built in Ireland.

Spin, hype and bluster cannot disguise the fact that quiet competence is missing. Dublin needs an integrated Luas network to show the “joined-up thinking” of which we have heard so much, and to get us out of the crisis caused by reliance on property development.

Geothermal energy in Ireland

GT Energy has applied for permission for a deep geothermal power plant in South Dublin. This has attracted some media attention (here, here, here) and Paul Cunningham cast me in my standard naysayer/party-pooper role.

The media attention is overblown. The project is small. It is only an application for planning permission. The legal framework for exploiting these resources has yet to be designed. Subsidies for geothermal power are zero at present.

The cost of geothermal energy depends, to a large extent, on the depth of the hole that needs to be drilled to get to the heat below our feet. In Iceland, Mother Nature nicely brings the hot water to the surface. GT Energy plans to drill 4 kilometers deep in South Dublin.

Unfortunately, Ireland is at a geological disadvantage in this regard (although mercifully free of volcanoes by the same token). As shown on this map (peer-reviewed version here, but in B&W and behind a pay wall), you’d need to drill deeper in Ireland than elsewhere in Europe to get to the hot stuff.

Therefore, if GT Energy can get this to work at a profit in Ireland, they’d be best advised to apply the technology elsewhere and make buckets of money. I will not invest in their company, but others are free to try their luck.

Landfilling waste

The EPA has released a new report on landfill, showing that environmental and nuisance management is much, much better than it used to be. It also contains an action plan to further improve things.

In an interview with the Irish Times, Dara Lynott adds that Ireland is likely to meet its landfill target for 2010 (I disagree) but not after that (I agree) as too little effort is made to provide alternatives to landfill.
