Shell E&P Ireland has welcomed the outcome of two court rulings in relation to planning approval for its Corrib gas terminal at Bellanaboy, north Mayo.
It has also denied that there are any difficulties with water quality in Carrowmore lake as a result of run-off from the terminal site.
On Thursday, Ms Justice Fidelma Macken turned down a Supreme Court appeal application by Martin Harrington over her earlier High Court decision to refuse leave for a judicial review. She also refused to refer the case to the European Court of Justice.
"This means that no further challenge to the gas terminal planning permission can now be brought by way of judicial review," Shell E&P Ireland said in a statement.
The company also welcomed a separate High Court ruling by Mr Justice Thomas Smyth last Tuesday, which confirmed that Shell had not breached the conditions of its planning permission for the Bellanaboy gas terminal.
Andy Pyle, Shell E&P Ireland's managing director, said that the company was fully committed to following due process in relation to the Corrib gas project and "takes very seriously its responsibility to comply with planning conditions and all consents it has obtained in relation to the project".
"Shell has worked closely with Mayo County Council to implement the planning conditions set by An Bord Pleanála when it granted permission for the gas terminal and will continue to do so in the future."
The company has emphatically denied claims by the Shell to Sea campaign that water quality in Carrowmore lake is being affected by run-off from the Bellanaboy terminal site.
A company spokesman said that Mayo County Council had also denied these claims. The spokesman described the protest on the site this week by objectors as "provocative" and in breach of health and safety regulations.
The Minister for the Marine is still deliberating on recommendations drawn up by his advisory group on the safety of the onshore pipeline. Mediation involving objectors to the pipeline and Shell is also currently suspended.
