A fire broke out at approximately 11:30 a.m. in an operating cell of a non-hazardous waste landfill site. The alert was raised by a local resident. The fire involved 2,000 t of common industrial waste (plastics, mattresses, etc.) over an area of 3,200 m² and to a depth of 4 m. A large column of black smoke was visible from several kilometres away. About forty firefighters arrived at the scene with a dozen or so vehicles, including high-powered foam trucks. The waste was sprayed down with 3 nozzles. A public works company cleared out the stock of waste with a power shovel and a bulldozer and transferred it to another cell. Air quality measurements were carried out. The results of these tests led people to equip themselves with cartridge masks during the intervention. A firefighter, having sustained a knee injury, was taken to the hospital. The intervention ended on 16/09 at the end of the day, but the fire resumed on 17/09 around 8 p.m. on 350 m² of waste. The fire brigade was able to bring the flames under control at around 9:30 p.m. They were able to extinguish yet another fire which had started again the next morning.

The acceptance of the work on the new cell (including the cell impacted by the fire), undertaken for a cost of 1.7M Euros, was scheduled for early October.

The waste collection site associated with the landfill site continued to operate normally. Major rehabilitation work is required at the landfill site.

The community operating the site filed a complaint, and the gendarmerie conducted an investigation.

A series of fires already occurred on the site in July 2012 (ARIA 42950) and more recently in the spring with a rapidly contained fire. According to the Inspection authorities for classified facilities, self-heating and deep self-ignition could have been the cause of the fire.
