The Corrib gas project entails exploiting a natural gas deposit off the northwest coast of Ireland. The field is located about 80 km off Erris Head in County Mayo, in water depths of 355 metres. The natural gas field, discovered in 1996, was the first reported commercial natural gas discovery in Ireland since the Kinsale Head gas field in 1973. The gas is from Triassic strata. The company set up to exploit the field is a conventure of Shell E&P Ireland (operator 45%), Statoil Exploration (Ireland) Limited (36.5%), and Marathon International Petroleum Hibernia Limited (18.5%). Reserves in the field are believed to be about 30 billion cubic metres (1 trillion ft³) 70% the volume of the Kinsale field.

The Shell to Sea campaign opposes the current plans for the project, which it regards as dangerous, despite assurances from Shell^[1]. The level of opposition to the current configuration of the project has led to a large amount of security at the refinery building site at Bellanaboy.

Shell have proposed to develop the Corrib field as a sub-sea production facility with onshore processing. This method of development is claimed by Shell to be in line with best industry practice for gas fields of this type, but no other refinery in the developed world is both as close to a residential community and regional water supply. Many people, including local residents, are concerned about the health, safety and environmental impact of the onshore aspects of the scheme, and, citing Shell's record ^{[2] [3] [4] [5] [6]}, do not believe the company's assurances. Others are concerned with alleged irregularities and precedents surrounding the project. Sinn Féin called for an inquiry into the Corrib deal as early as 2001. Protests by residents have been ongoing daily at the refinery site since the summer of 2005, when five local men were jailed for contempt of court after refusing to obey a court injunction to allow Shell workers on their lands.

The Shell to Sea campaign, which is attempting to have the gas refined at sea rather than inland, was created during their imprisonment. A poll conducted throughout the county by TNS/MRBI on behalf of RTÉ's Nuacht in September 2006^[7] 60% felt the terminal should be located offshore at sea, with less than a quarter supporting the current plans. The offshore alternative has strongest support amongst those aged under 49 years, and those residing in Castlebar/Ballinrobe/ Claremorris and Westport/Belmullet areas."

[edit] Project proposal

There are four parts to the proposed Corrib project:

1. the offshore operations including the wells and subsea facilities
2. the offshore section of the pipeline
3. the onshore section of the pipeline
4. the gas processing plant at Bellanaboy

The second two have proved extremely contentious, and were objected to by both An Taisce ^[8]and Dúchas (Dúchas was abolished not long after this objection). Planning permission for the refinery was originally refused unequivocally, and the onshore section of the pipeline was not subject to any planning regulation due to a loophole.

[edit] Controversy

[edit] Political opponents

Michael Ring was the highest-profile Fine Gael opponent of the onshore refinery until performing a U-turn on the issue. No Fine Gael or Progressive Democrat elected representative now opposes the inland terminal. Newport councillor, former Senator, Frank Chambers and Belmullet councillor Tim Quinn are the only Fianna Fáil politicians in support of refining offshore. Sinn Féin backs the Shell to Sea campaign as policy, though local Sinn Féin member Paddy Ruddy has been employed by Shell^[9], as did the Green Party until they entered government with Fianna Fáil and the PDs. Much of the Labour Party opposes the current project configuration, with party president Michael D. Higgins being the most prominent opponent.

[edit] Safety and Environmental Concerns

[edit] Refinery Site

Planning permission for the refinery was refused unequivocally by Senior Planning Inspector Kevin Moore, of An Bord Pleanála (the Irish planning authority). His report stated: "From a strategic planning perspective, this is the wrong site; from the perspective of Government policy which seeks to foster balanced regional development, this is the wrong site; from the perspective of minimising environmental impact, this is the wrong site; and consequently, from the perspective of sustainable development, this is the wrong site. At a time when the Board is now required, in accordance with the Local Government (Planning and Development) Act, 2000, to have regard to the proper planning and sustainable development of an area in which a development is proposed to be constructed, it is my submission that the proposed development of a large gas processing terminal at this rural, scenic, and unserviced area on a bogland hill some 8 kilometres inland from the Mayo coastland landfall location, with all its site development works difficulties, public safety concerns, adverse visual, ecological, and traffic impacts, and a range of other significant environmental impacts, defies any rational understanding of the term “sustainability”. It is an irony that this large industrial proposal is linked with a natural gas resource, the exploitation of which adheres to the concept of sustainability."

The cleaning terminal will require in excess of 120 Megawatts of power to operate^{[citation needed]}, the power would coming from burning off the uncleaned gas condensate, containing oxides of carbon and nitrogen, sulphur dioxide, methane and ozone^{[citation needed]}. There will be nine chimneys, four of them approximately 140 feet (43 m) high^{[citation needed]}. These would release carbon dioxide and methane equivalent to the global warming potential of 27,000 dairy cows.^{[citation needed]}

The waste water problem is twofold:

1. There is a pipe to take waste impurities to sea and a perforated perimeter ditch which would surround the drainage from the site.
2. The waste water storage sump is designed to withstand only a few hours of continuous rainfall, though nearby Crossmolina had 106 days of consecutive rainfall during the autumn of 2004. Overflow from the sump will flow into Carrowmore Lake, the drinking water supply of 10,000 Erris residents^[10].

This untreated waste water would contain many toxic substances, including lead, nickel, magnesium, phosphorus, chromium, arsenic, mercury and the radioactive gas radon^{[citation needed]}. Aluminium levels in the lake (due to runoff from the construction) are far in excess of World Health Organisation limits^[11]. Carrowmore Lake was declared unsafe in early summer of 2007.^{[citation needed]}

The refinery would be constructed on blanket bog. Shell’s plan to stabilise this involves mixing in cement to form a hard surface. This process has not previously been used on such a large scale and creates a reaction which produces the very toxic hexavalent chromium.^{[citation needed]}

The Environmental Protection Agency awarded a licence to operate the refinery in November 2007, more than two years after construction began.

[edit] Pipeline Route

The upstream high pressure gas pipeline that connects the well to the inland refinery site runs through the area of Rossport, close to local residences. The pressure inside the pipeline is comparable to that of the highest pressure Bord Gáis pipelines and will be going through boggy land with a recent history of serious landslides. The gas pipeline would also have adjoining pipelines carrying hydraulic fluid, cleansing acids and a waste pipe, as well as electric cables. The Accufacts report by Dr. Richard Kupriewicz (acknowledged by the government as legitimate) said "the terrain makes escape routes for the clustered population essentially impossible in the event of a rupture" ^[12]. He went on to say "that the pipeline re-route option difficulties have been substantially overstated".

Frequently described as a "high pressure" pipeline, it is claimed the pipeline will have a usual operating pressure of 120 Bar while the maximum expected is 345 Bar. The raw gas from the field is odorlesss. In contrast, in Kinsale the gas is refined at sea and piped ashore at a much lower pressure and odorised^{[citation needed]}. The highest pressure Bord Gáis pipelines, in the transmission network, bringing gas under the sea from Scotland, runs at up to 150 Bar pressure^[13].

The large pressure is necessary as the pipeline would be pumping the gas straight out of the field to the onshore refinery, whereas normally the refining takes place out at sea. Current legislation applies only to offshore upstream pipelines and to onland ones with similar levels of pressure to those used by Bord Gáis. The Irish government decreed the pipeline was not to be subject to planning permission as they considered it an offshore development, though it runs inland for over 9 km.

[edit] Broadhaven Bay

Broadhaven Bay is the proposed area to discharge toxic waste from the refining process^[14] Due to the bay’s circular tidal pattern and semi-enclosed nature this toxic waste is more likely to stay within the bay rather than be washed out to sea.^{[citation needed]}

A UCC research team found that the bay was an important breeding and rearing area for whales and dolphins ^[15]. They recorded over 220 sightings of seven whale and dolphin species including sightings of the relatively rare Risso's Dolphin, plus sightings of two seal species and marine mammals such as basking sharks and a sea turtle in Broadhaven Bay and north-west Mayo waters.

Broadhaven Bay is a Special Area of Conservation under European Union regulations. According to state heritage agency Dúchas “Broadhaven Bay supports an internationally important number of Brent Goose” as well as regionally important populations of other birds. The pipeline would also pass through the machair sand dunes/coastal grasslands at one end of Broadhaven Bay.

[edit] Shell's reputation

Aside from the immediate safety and environmental concerns, many Erris residents have serious qualms about having Shell as a neighbour given their past record, especially in Nigeria ^[16] (see controversies surrounding Royal Dutch Shell and Ken Saro-Wiwa).

[edit] Safety reviews

The Minister for Communications, Marine and Natural Resources, Noel Dempsey, commissioned a company to produce what was called an "Independent Safety Review" of the pipeline. After the company produced its report, it emerged that it was jointly owned by Shell and British Petroleum. Dempsey denied the report was compromised but agreed to commission another. The second review was strongly criticised by those opposed to the project for failing to consider alternatives to refining the gas onshore. Another company, Accufacts Inc., also produced a report on the pipeline^[17] for the Centre for Public Inquiry, it was highly critical of the current plans for the pipeline, and skeptical of the assurances given. It said:

"It should be fairly obvious by now that past information on this project has been less than complete. Much of this information appears to be of a propaganda nature intended to spin public relations to an ill informed or misinformed public or government. In today’s information age this is a tactic fraught with risks as the deceptions are uncovered. Regarding the proposed onshore pipeline route, serious challenges should be raised as to any risk analysis that fails to adequately address the issues raised by the production pipeline, as the thermal impact zones for this very unique high pressure pipeline are quite large with a high probability of mortality..."

"If the Gas Processing Plant site location were to remain as proposed, we advise a reroute of the proposed pipeline incorporating safety buffer zones of 200 metres for dwellings and at least 400 metres for unsheltered individuals."

"Placement of a Gas Process Plant on a shallow offshore platform would substantially reduce production pipeline rupture impact zones associated with specific pipeline design modifications. A transmission pipeline from such an offshore facility could be operated at lower pressures, move much higher quality gas, and permit appropriate cleaning and smart pigging programs that would reduce the potential impact zone associated with a gas transmission pipeline failure."

Other experts have also cast doubt on Advantica's claims. Some contend that the safety zone around the pipeline should be at least 500 metres (the norm in the United States) from any dwellings [1]. Philip McGrath, jailed for three months for his opposition to the original pipeline route, lives within 70 metres of it. In Scotland, which has a long history of regulating refineries, it is unheard of that a refinery should be built within the catchment area of a drinking water supply, as Shell intends for Bellanaboy [2].

In an effort to resolve issues, the OECD is to host talks between Pobal Chill Chomáin and Shell EP Ireland, mainly centred on a complaint by Pobal Chill Chomáin that the project violates OECD guidelines for multinational companies. ^[18]
