An underground fire which has been smouldering in Guernsey's landfill site for more than two and a half years could cost £43,000 to extinguish.
The fire at Mont Cuet was discovered in April 2005 when boreholes were dug and abnormally high temperatures were recorded inside the waste.
The fire started when oxygen managed to seep into the landfill.
Public Services Minister Bill Bell said there had been several unsuccessful attempts to put it out.
In 2006, after water failed to douse the fire, arrangements were made to bring a team of specialists from the UK to use nitrogen on the fire.
A States spokesman said constant checks are carried out on the site.
